+## v0.4 Architecture (Refinement — NFR)
+
+v0.4 is a refinement-only NFR milestone (D-047): zero `feat:` phases, zero new
+production types, zero behavioral changes. It lands durability fixes sourced
+from v0.3 forward-references. Tags run on the `v0.3.x` patch line.
+
+### v0.4 Research Findings
+
+**R-029 — Lexicon firewall shared helper (REQ-029, GRILL G-014).**
+
+Verified during v0.4 RESEARCH: `lexicon_meta_test.go` (`TestLexiconMetaSelfTestTable`, lines 83-118) and `lexicon_meta_docs/lexicon_meta_docs_test.go` (`TestLexiconMetaDocsSelfTestTable`, lines 147-182) contain byte-identical duplicate synthetic self-test tables — both build the same 10-string slice by indexing `lexicon.BannedTerms()`. This is exactly the G-014 drift risk: if a future banned-term addition updates one table and not the other, the docs firewall silently loses coverage. The fix is a new `lexicon.SyntheticBannedStrings() []string` helper in `lexicon/lexicon.go` that returns the 10 synthetic strings; both meta-tests consume it instead of building their own copy. The helper's source uses `lexicon.BannedTerms()` (already fragment-assembled) so the lexicon package's own source stays lexicon-clean. Both meta-tests already assert `len(terms) == 10` from `lexicon.BannedTerms()` (the G-014 minimum); the helper closes the drift fully. No behavioral change to detection (`FindBannedTerm` unchanged); refactor + test only.
+
+**R-030 — Cross-package const-equality test (REQ-030, REVIEW P2 / A-304).**
+
+Verified during v0.4 RESEARCH: `x/hub/types/types.go:51,56` defines LOCAL consts `LendingCouponCapBps = uint32(800)` and `LendingCouponFloorBps = uint32(0)`, cross-documented (comment lines 46-55) to `x/bond/types/types.go:21,26` consts `CouponCapBps = 800` and `CouponFloorBps = 0` (D-028 mission-locked). The cross-doc comment flags drift for human review but no automated check exists. The fix is a new test file `x/hub/types/cross_const_test.go` (package `types`) that imports `github.com/oy/openyield/x/bond/types` (test-only, G-003 exempt per the test-import exemption documented in v0.2 GRILL G-003) and asserts `hub.LendingCouponCapBps == bond.CouponCapBps` and `hub.LendingCouponFloorBps == bond.CouponFloorBps`. The test fails closed if either const drifts. No production import is added (G-003 production firewall intact); test-only import only.
+
+**R-031 — Lifecycle type shape-divergence review (REQ-031, AUDIT §193).**
+
+Verified during v0.4 RESEARCH: AUDIT §193 flags two P1 council divergences and one P2 bearers nit:
+- **P1-1**: `x/council/types` lacks `Proposal`/`ProposalStatus`/`VoteOption` enums (AUDIT says add "in v0.3 when wiring the council keeper to a live governance runtime"). Adding these is a `feat:`-class addition (new enum types) → REJECTED by D-001 filter for v0.4. Deferred to v0.5+ governance runtime.
+- **P1-2**: `SignalKind` has 4 sources (Stash/Standing/Vouch/Capital) vs spec's `VoiceSource` 5 sources (Stash/Standing/Vouch/Freeholder/Guild). AUDIT code rationale: Freeholder is an eligibility property (upstream in `x/standing`), Guild is a council tier, Capital is committed-capital (vision §9.1) — defensible refinement. Changing `SignalKindCount` 4→5 is a locked-const change → REJECTED by D-001 filter for v0.4.
+- **P2**: `x/bearers/types` `ValidateGenesis` no-op is CORRECT per spec (AUDIT explicitly notes "no action").
+
+v0.4 REQ-031 scope (D-050): DOCUMENT the divergence decisions in this ARCHITECTURE.md section + add a regression-guard test asserting the current `SignalKindCount==4` shape is intentional (an intent-assertion test, not a shape change). No enum additions, no locked-const changes. The existing `TestSignalKindCountLockedConst` in `x/council/types/types_test.go:102` already asserts the count; REQ-031 adds an intent comment + a test documenting WHY the shape is 4-not-5 (the AUDIT rationale), so a future agent does not "fix" the divergence by silently changing the locked const.
+
+**R-032 — Docs build CI (REQ-032, D-046).**
+
+Verified during v0.4 RESEARCH: no `.github/workflows/` directory exists; Gitea Actions uses `.gitea/workflows/`. `mkdocs.yml` is present at repo root (buildable locally via `mkdocs build`). v0.4 REQ-032 ships a `.gitea/workflows/docs-build.yml` workflow that: (1) runs `go test ./...` (the lexicon firewall + all x/* tests) on push; (2) installs mkdocs + mkdocs-material (build-only Python deps in a separate job/step — does NOT touch `go.mod`, G-006 intact); (3) runs `mkdocs build` to produce `site/`; (4) uploads `site/` as a CI artifact. Full Gitea Pages publishing is DEFERRED (no hosting target configured in v0.4 per D-051). The workflow file is `chore` (CI config), not `feat:` — passes the D-001 filter. The workflow runs on every push to any branch (not just main) so the lexicon firewall + docs build are checked on every change.
+
+### v0.4 Component Map (no new modules)
+
+v0.4 touches NO new `x/*` modules. The touched files are:
+- `lexicon/lexicon.go` (add `SyntheticBannedStrings()`) — REQ-029
+- `lexicon_meta_test.go` (refactor to consume helper) — REQ-029
+- `lexicon_meta_docs/lexicon_meta_docs_test.go` (refactor to consume helper) — REQ-029
+- `x/hub/types/cross_const_test.go` (NEW test file) — REQ-030
+- `x/council/types/types_test.go` (add intent-assertion test + comment) — REQ-031
+- `.ciagent/oy/ARCHITECTURE.md` (this section) — REQ-031
+- `.gitea/workflows/docs-build.yml` (NEW CI workflow) — REQ-032
+
+### v0.4 Interface Contracts (unchanged from v0.3)
+
+v0.4 does not change any cross-component interface. The 6 cross-component interfaces (Standing, Forge/Fold, Mirror, Window, Fee Covenant, Voice/Council) are unchanged. REQ-031 documents a divergence in the Voice/Council interface surface (SignalKind shape) but does not change it.
+
+### Council Voice/Council Interface — Lifecycle Type Divergence Decisions (v0.4, REQ-031)
+
+This section documents the lifecycle type shape-divergences flagged by AUDIT.md §193 for the Council/Voice interface surface. v0.4 is a refinement-only NFR milestone (D-047): the D-001 filter REJECTS `feat:`-class enum additions and locked-const shape changes, so these divergences are DOCUMENTED here, not fixed in code. A regression-guard test (`TestSignalKindShapeIntentional` in `x/council/types/types_test.go`) locks the current shape so a future agent does not silently "fix" a divergence by changing a locked const.
+
+**Divergence P1-1 (AUDIT §193): `Proposal`/`ProposalStatus`/`VoteOption` enums absent from `x/council/types`.**
+
+- **Spec source**: P3-01-01 deliverable recommended `Proposal`, `ProposalStatus` (5 states), `VoteOption` (3 options) enums mirroring OZ Governor / `x/gov`.
+- **Implemented**: `Council`, `CouncilMember`, `Voice`, `SignalKind`, `TallyResult` — no `Proposal`/`ProposalStatus`/`VoteOption` lifecycle types.
+- **Must-have impact**: NONE. The v0.2 P3 must-haves (3 councils, Mission Lock, `TallyResult` x/gov shape, no veto) are all met without the Proposal lifecycle.
+- **Decision (v0.4, D-050)**: ADDING `Proposal`/`ProposalStatus`/`VoteOption` is a `feat:`-class addition (new enum types). REJECTED by the D-001 refinement-only filter. **Deferred to v0.5+** when the council keeper is wired to a live governance runtime (the AUDIT's own recommendation: "add in v0.3 when wiring the council keeper to a live governance runtime"). The skeleton council keeper in v0.2 does not consume a Proposal lifecycle; adding the types without the runtime would be dead code.
+- **Severity (AUDIT)**: P1 (spec drift from deliverable text, not a must-have, not blocking).
+- **v0.4 action**: DOCUMENT only (this section). No code change.
+
+**Divergence P1-2 (AUDIT §193): `SignalKind` 4 sources vs spec `VoiceSource` 5 sources.**
+
+- **Spec source**: P3-01-01 deliverable specified `VoiceSource` with 5 sources (Stash/Standing/Vouch/Freeholder/Guild).
+- **Implemented**: `SignalKind` with 4 sources: `SignalStash`, `SignalStanding`, `SignalVouch`, `SignalCapital` (`SignalKindCount = 4`, locked const).
+- **Code rationale (AUDIT §193 P1-2)**: the 4-source shape is a defensible design refinement, not a defect:
+  - `Freeholder` is an ELIGIBILITY property (upstream in `x/standing`), not a voice signal. A Freeholder-eligible Reach is a precondition for voting, not a signal that feeds a vote's weight.
+  - `Guild` is a COUNCIL TIER (one of the three councils is the Guild Council), not a voice signal. Including Guild as a signal kind would conflate the council tier with the signal source.
+  - `Capital` is committed-capital (vision §9.1, one of the four Freeholder signals), which the spec's `VoiceSource` list omitted. Adding `Capital` corrects the spec list to match vision §9.1's four-signal definition (REQ-005: "Four Freeholder signals locked").
+- **Must-have impact**: NONE. The v0.2 P3 must-haves did not enumerate `VoiceSource` coverage; the 4-signal shape matches REQ-005's "Four Freeholder signals locked" exactly.
+- **Decision (v0.4, D-050)**: changing `SignalKindCount` 4→5 (to restore the spec's 5-source `VoiceSource`) is a LOCKED-CONST CHANGE. REJECTED by the D-001 refinement-only filter (changing a locked const is a behavioral change, not a refinement). The 4-source shape is the CORRECT shape per vision §9.1 and REQ-005; the spec deliverable text was wrong, not the implementation.
+- **Severity (AUDIT)**: P1 (design-choice divergence, tested and self-consistent, not blocking).
+- **v0.4 action**: DOCUMENT the rationale here + add `TestSignalKindShapeIntentional` (regression guard) so a future agent changing `SignalKindCount` from 4 to 5 must also update the intent-assertion test, surfacing the AUDIT rationale for review. No locked-const change.
+
+**Divergence P2 (AUDIT §193): `x/bearers/types` `ValidateGenesis` no-op.**
+
+- **Spec source**: P4-02-01 said "DefaultParams/GenesisState unchanged" (bearers is an EXTENSION in v0.2, not a new module; the A-212 `ValidateGenesis` upgrade was scoped to NEW modules only).
+- **Implemented**: `ValidateGenesis` remains a no-op (`x/bearers/types/types.go:108` returns `nil` unconditionally).
+- **Decision (v0.4)**: CORRECT per spec — no action (AUDIT explicitly notes "no action"). The A-212 upgrade applies to NEW modules (v0.2's `x/window`, `x/stand`, etc.), not to EXTENDED modules like `x/bearers`. Listed here for completeness; no code change, no test change.

+
+## v0.5 Runtime Architecture (Bearers Runtime)
+
+This section appends the v0.5 runtime architecture to the v0.1/v0.2/v0.3/v0.4
+content above. It does NOT rewrite or supersede earlier sections. v0.5 is the
+first **feature** milestone to ship executable behavior: the v0.3 Bearers
+skeletons are promoted from types + in-memory keeper stubs + invariant tests
+to **live keeper MsgServer message handlers + simtest-grade end-to-end flows**
+(D-054). This is NOT mainnet — D-020 continues to govern network deployment;
+runtime = simtest-grade handlers, not live chain. Tags run on the `v0.4.x`
+patch line (config.json `tag_base`).
+
+### v0.5 Skeleton→Runtime Promotion Pattern
+
+The promotion is uniform across all 8 target modules. The v0.3 skeleton
+baseline (verified against the current tree): each module has only a `types/`
+subdir with `types.go` (pure-Go structs + locked consts + enums),
+`genesis.go` (`ValidateGenesis`), and `*_test.go` (invariant + lexicon
+tests). The in-memory `Keeper` stub lives INSIDE `types/types.go` (e.g.,
+`x/partner/types/types.go:101 type Keeper struct{...}`, `NewKeeper()` returns
+`&Keeper{partners: make(map[string]Partner)}`). There is NO `keeper/` subdir,
+NO `msg_server.go`, NO `types.Msg*`, NO `sdk.Context`, and NO cosmos-sdk
+import anywhere in `x/` (grep for `cosmos-sdk` / `sdk.Context` /
+`cosmos/cosmos` returns zero matches — verified at v0.5 P0).
+
+v0.5 promotes each module per the Cosmos-SDK `MsgServer` convention:
+
+| Layer | v0.3 skeleton | v0.5 runtime addition |
+|---|---|---|
+| Keeper | in-memory `map[string]T` in `types/types.go` | `keeper/keeper.go` (store-backed, wraps `sdk.KVStore`); the v0.3 stub is retired or wrapped as a test helper |
+| Messages | none | `types/msg_*.go` with `Msg*` structs implementing `sdk.Msg` (`ValidateBasic`, `GetSigners`) |
+| Handlers | none | `keeper/msg_server.go` with `MsgServer` + one `*Response, error` method per `Msg*` |
+| Module wiring | none | `module.go` (`AppModule` with `RegisterServices` registering the `MsgServer`); simtest may use a lighter `ModuleManager` shim |
+| End-to-end test | invariant tests only | `simtest/` (or `keeper/msg_server_simtest_test.go`) exercising each handler against an in-memory `sdk.Context` |
+| Cross-module deps | by-ID-string only (G-003) | by-ID-string preserved at the type level; keeper-to-keeper calls via `expected_keepers.go` interface shims (ibc-go convention) |
+
+The existing `types/` locked consts, enums, and structs are NOT amended —
+the runtime layer adds behavior on top, not changes to the contract. The
+locked-const firewall (8%/0% bond cap, 6 bearers, 4 Partner tiers, Mission
+Lock non-amendable, etc.) stays green.
+
+### v0.5 Per-Module Runtime Surface
+
+| Module | REQ | Phase | Runtime surface (MsgServer handlers) | Key types added/extended |
+|---|---|---|---|---|
+| `x/exit` | REQ-033 | P1 | `MsgSubmitExitRoute`, `MsgExecuteDEXSwap`, `MsgRefundExit` driving the v0.3 `ExitStatus` lifecycle (Proposed→InProgress→Settled/Failed/Refunded) | `Msg*` types; cross-chain exit invokes `x/bridge` via `BridgeKeeper` expected-keeper shim |
+| `x/bridge` | REQ-033 | P1 | `MsgAttestBridgeRoute` (Pending→Attested via Watcher quorum), `MsgActivateBridge`, `MsgCloseBridge`, `OnRecvPacket`, `OnAcknowledgementPacket`, `OnTimeoutPacket` (ibc-go `IBCModule` contract) | `Msg*` types; ICS-20 v1 payload parser; Solana via wormhole-adapter verification branch (D-059) |
+| `x/bearers` | REQ-034 | P2 | `MsgSendOYSATFrame`, `MsgReceiveOYSATFrame`, `MsgIssueOYQR`, `MsgConsumeOYQR` (one-shot) + session lifecycle (Open/Active/Closed/Revoked) | `Session` struct; store-backed `BearerTransport` impl (keeper as transport in simtest); `consumed` flag is the OY-QR replay firewall |
+| `x/partner` | REQ-035 | P3 | `MsgIssueAnchorCredential`, `MsgOnboardAnchor` (Pending→Onboarded), `MsgSuspendAnchorCredential`, `MsgRevokeAnchorCredential` (Watcher-quorum authz) | `Msg*` types; `expected_keepers.go` shims for `x/watcher` (revocation authz) and `x/hub` (custody-provider-id validity, P4-wired) |
+| `x/hub` | REQ-036 | P4 | `MsgRegisterCustodyService` (operator must be Onboarded Anchor), `MsgCustodyReceiveAsset`, `MsgCustodyReleaseAsset` (compliance-before-debit), `MsgRecordLendingPrimitive` (coupon clamp [0,800]), `MsgRecordComplianceAttestation` | `CustodyKeyring` interface + `memKeyring` in-memory test impl (D-058); `Msg*` names avoid banned "deposit" (lexicon) |
+| `x/services` | REQ-037 | P5 | `MsgRegisterService` (window-grant check), `MsgActivateService`, `MsgSuspendService`, `MsgRevokeService`; per-kind: `MsgIssueCareGrant`, `MsgActivateSIM`, `MsgProvisionVault`, `MsgBindMailbox` | Per-kind `Msg*` (typed dispatch, not generic); `window-id` grant checked on EVERY op (revoked Window invalidates) |
+| `x/bond` | REQ-038 | P6 | `MsgIssueBond`, `MsgIssueGrowthBond` (`Clamp` + `ClampGrowth`), `MsgTickGrowthBond`, `MsgPlaceSecondaryOrder`, `MsgCancelSecondaryOrder`, `MsgMatchSecondaryOrder` (CLOB, price-time priority, per-match clamp) | CLOB matching engine; per-match coupon clamp to [0, 800] bps via v0.3 `Clamp` (D-057/D-028); match above 800 REJECTED (fails closed, A-562) |
+| `x/council` | REQ-039 | P7 | `MsgSubmitProposal` (MissionLockAmendment kind rejected at `ValidateBasic`), `MsgVote` (Veto is Watcher-only, quorum-based), `MsgTallyProposal` | `Proposal` struct + `ProposalKind` enum (4, incl. rejected MissionLockAmendment) + `ProposalStatus` enum (5) + `VoteOption` enum (4) — AUDIT §193 P1-1 promotion; `SignalKind` stays 4 (P1-2 defensible); Mission Lock const firewall intact |
+
+### v0.5 Custody Keyring Interface Boundary (D-058)
+
+`x/hub/types/keyring.go` defines the `CustodyKeyring` Go interface — the
+custody key-share abstraction (MPC-via-interface, not a concrete HSM/MPC
+vendor):
+
+```
+type CustodyKeyring interface {
+    Sign(ctx context.Context, assetID string, payload []byte) (sig []byte, err error)
+    Derive(ctx context.Context, assetID string) (pub PubKey, err error)
+    Status(ctx context.Context, assetID string) (KeyringStatus, error)
+}
+```
+
+- v0.5 ships an in-memory test-only `memKeyring` impl (`x/hub/keeper/
+  keyring_mem.go` or `x/hub/types/keyring_mem_test.go`) that signs with a
+  throwaway ed25519 key. Real MPC/HSM backing is deferred (operational,
+  Year 3+).
+- The interface supports key rotation: `Status` reports the active key
+  version; the handler consults the keyring per operation (no caching
+  across blocks — a cached pubkey breaks rotation).
+- The boundary keeps v0.5 dep-neutral w.r.t. custody vendors while landing
+  the handler surface. GRILL reviews the interface boundary.
+
+### v0.5 CLOB Matching Engine Invariants (D-057)
+
+`x/bond` secondary-market matching is a **central-limit order book (CLOB)**
+(not an AMM — D-057 rejects AMM as a Year-4 concern). The invariants:
+
+1. **Price-time priority** — at the same price, the earlier resting order
+   fills first (by sequence). This is REQ-007 FCFS at the same price.
+2. **Per-tx matching** — the handler matches a new order against the resting
+   book in the same tx (dYdX-v4-shaped); no asynchronous / end-of-block
+   batch matching in v0.5 simtest.
+3. **Per-match coupon clamp** — every match's resulting coupon is clamped to
+   `[CouponFloorBps=0, CouponCapBps=800]` (D-028, locked since v0.2) via the
+   v0.3 `Clamp` helper. A match whose implied coupon exceeds 800 bps is
+   **REJECTED** (fails closed — A-562, the mission-lock-true choice; D-057
+   says "clamp", the runtime interpretation is reject-above-cap. Planner
+   confirms before P6).
+4. **Mission-lock const firewall** — the handler references the consts
+   directly (not a local copy); the REQ-030 cross-const test (hub lending
+   consts == bond consts) stays green.
+5. **No front-running safety claim** — per-tx matching in a single-
+   validator simtest has no MEV; the handler is documented as NOT
+   front-running-safe for mainnet (a Year-3+ concern). Simtest does not
+   assert front-running safety (out of scope for simtest-grade runtime,
+   D-054).
+
+### v0.5 IBC Packet Handler Scope (D-059)
+
+`x/bridge` IBC packet handlers cover the **5 locked L2 chains** already in
+the v0.2 `x/satellite` skeleton (Polygon, Base, Arbitrum, Optimism, Solana
+per REQ-009). No new L2 chains in v0.5. The handler shape:
+
+- **4 EVM chains (Polygon/Base/Arbitrum/Optimism):** standard IBC
+  recv/ack/timeout on the ICS-20 v1 payload (the v0.2 satellite packet
+  shape). Timestamp-only timeouts (IBC Eureka model, ibc-go v10) avoid the
+  EVM height-timeout ambiguity.
+- **Solana:** via the wormhole-style bridge adapter (D-021 stub promoted
+  to runtime). Solana packets arrive as wormhole VAAs (Verified Action
+  Approvals); the `x/bridge` handler verifies the guardian signature set
+  (a 2-of-N quorum, N = the wormhole guardian set) before transitioning the
+  route. The guardian set is read from state (not hardcoded); simtest uses
+  a frozen stub guardian set. Live wormhole integration deferred (D-054).
+- **Replay protection:** mirrors ibc-go — delete the in-flight record on
+  first ack; reject on second; `OnTimeoutPacket` refunds the source-chain
+  escrow exactly once. Simtest covers both replay and timeout-refund cases
+  (the CVE-class ibc-go pitfall).
+
+### v0.5 Council Governance Enum Additions (D-060)
+
+`x/council/types` gains the AUDIT §193 P1-1 enums deferred from v0.4
+(D-050/D-001 rejected them as `feat:` for the NFR milestone; v0.5 promotes
+them as the feature milestone's P7):
+
+| New type | Values | Locked count | Notes |
+|---|---|---|---|
+| `Proposal` struct | (id, council-id, kind, proposer-reach, submit-time, voting-deadline, status, tally) | — | Mirrors OZ Governor / `x/gov` proposal shape |
+| `ProposalKind` enum | `Stand`, `Guild`, `Mesh`, `MissionLockAmendment-Rejected` | `ProposalKindCount = 4` | The 4th value exists but the handler rejects it — documents the non-amendability in code |
+| `ProposalStatus` enum | `Pending`, `Active`, `Succeeded`, `Failed`, `Executed` | `ProposalStatusCount = 5` | Mirrors OZ Governor / `x/gov` lifecycle |
+| `VoteOption` enum | `Yes`, `No`, `Abstain`, `Veto` | `VoteOptionCount = 4` | `Veto` is Watcher-only; quorum-based (default `WatcherVetoQuorum = 6` per REQ-004 6-of-9); a single Veto does NOT block (anti-greed, vision §19) |
+
+**Mission Lock const firewall intact (G-003):**
+- `MissionLockAmendable = false` (v0.2 locked const) is UNCHANGED. The
+  `MissionLockAmendment-Rejected` `ProposalKind` is the in-code
+  documentation of the non-amendability; the `MsgSubmitProposal`
+  `ValidateBasic` REJECTS a proposal of that kind (the message never
+  reaches the handler — A-572). The const is the firewall; the
+  `ValidateBasic` is the gate. The v0.2 `TestMissionLockAmendableFalse`
+  regression test stays green.
+- `SignalKind` stays at 4 sources (P1-2 defensible per AUDIT; the v0.4
+  `TestSignalKindShapeIntentional` regression-guard test stays green).
+  Expansion to 5 is a locked-const change deferred to v0.6+ governance
+  vote (not a Mission-Lock const — a distinct locked const; the distinction
+  is documented in v0.4 ARCHITECTURE.md).
+- Proposal execution (auto-executing a passed proposal) is NOT in v0.5;
+  the handler records the tally result but does not auto-execute (a v0.6+
+  concern).
+
+### v0.5 G-003 Production Firewall (still intact)
+
+The G-003 by-ID-string rule (no production cross-`x/<module>/types` struct
+imports) survives the runtime promotion. The runtime adds a NEW cross-
+module surface — keeper-to-keeper calls — handled via the ibc-go
+`expected_keepers.go` convention:
+
+- Each module's `types/expected_keepers.go` defines Go INTERFACES for the
+  keepers it depends on (e.g., `x/exit/types/expected_keepers.go` defines a
+  `BridgeKeeper` interface with the methods `x/exit`'s handler calls; the
+  `x/bridge` keeper satisfies it structurally).
+- The handler depends on the INTERFACE, not the concrete keeper struct.
+  This is NOT a struct import of `x/bridge/types`; it is an interface
+  defined in `x/exit/types`. G-003's intent (no cross-module struct
+  coupling, no import cycles) is preserved.
+- Test-only cross-package imports (the G-003 test exemption, used by
+  REQ-030 in v0.4) remain exempt: a simtest may import both
+  `x/exit/keeper` and `x/bridge/keeper` to wire the expected-keeper shims
+  in a test setup.
+
+### v0.5 G-006 Controlled Exception (cosmos-sdk dep, D-055)
+
+`go.mod` gains `github.com/cosmos/cosmos-sdk` (+ transitive deps) as the
+runtime substrate. This is a GRILL-approved controlled exception to G-006
+(zero-dep go.mod), scoped to the runtime promotion phases:
+
+- **Runtime phases (P1..P7):** `keeper/`, `msg_server.go`, `module.go`,
+  `simtest/` import cosmos-sdk. The dep is load-bearing.
+- **P0 (pre-execution) + P8 (final):** stay dep-neutral where possible
+  (RESEARCH.md, PERSONAS.md, PLAN — no Go code).
+- **`types/` packages:** the v0.3 `types/` packages were pure stdlib
+  (`encoding/json`); v0.5 ADDS `types.Msg*` structs implementing `sdk.Msg`,
+  so the `types/` package gains a cosmos-sdk import. The invariant tests
+  (locked-const, lexicon) stay stdlib-only and green. The `Msg*` types are
+  isolated in `types/msg_*.go` files for clarity.
+- **Version pin (A-504, planner/GRILL confirms):** cosmos-sdk v0.50.x
+  (LTS, go 1.22-compatible) + ibc-go v8.x (for cosmos-sdk v0.50) for the
+  IBC packet handler interfaces. ibc-go v10 (IBC v2 / Eureka) is the
+  documented target pattern but a newer pin; v8.x is the stable choice.
+  The exception is GRILL-ratified per D-055.
+
+### v0.5 Cross-Component Dependencies (within v0.5, by-ID-string + expected-keeper shims)
+
+Per the v0.2-v0.4 G-003 invariant, v0.5 components reference each other and
+the baseline by ID-string at the type level; the runtime adds interface-
+typed keeper dependencies via `expected_keepers.go` shims. The dependency
+edges that affect D-056 phase ordering:
+
+```
+x/exit    ──(BridgeKeeper interface)──►  x/bridge  (P1 intra-phase; bridge keeper satisfies x/exit/types expected keeper)
+x/bridge  ──(WatcherKeeper interface)──► x/watcher  (P1; Attested transition + Solana adapter authz)
+x/bridge  ──(BreadKeeper interface)───►  x/bread    (P1; mint/release wrapped Bread on recv/timeout)
+x/bearers ──(BreadKeeper interface)───►  x/bread    (P2; OY-QR consume transfer effect)
+x/partner ──(WatcherKeeper interface)──► x/watcher  (P3; revocation authz)
+x/partner ──(HubKeeper interface)─────►  x/hub      (P3→P4; custody-provider-id validity; shim exists P3, impl wired P4)
+x/hub     ──(PartnerKeeper interface)─► x/partner  (P4; operator must be Onboarded Anchor)
+x/hub     ──(lexicon-safe consts)─────► x/bond     (P4; LendingCouponCapBps/Floor local consts cross-documented D-028/REQ-030)
+x/services ──(WindowKeeper interface)──► x/window  (P5; window-grant validity on every op)
+x/services ──(VaultKeeper interface)───► x/vault    (P5; VaultService provisioning)
+x/bond    ──(StandKeeper interface)───► x/stand     (P6; GrowthBond issuer-stand-id)
+x/council ──(WatcherKeeper interface)──► x/watcher  (P7; Veto authz + quorum)
+```
+
+**Phase-ordering implication (confirms D-056):** the outer→inner chain is
+exit (P1) → bearers (P2) → anchors (P3) → hub (P4) → services (P5) → bond
+(P6) → council (P7). The P3→P4 edge (partner needs hub custody-provider-id
+validity) is broken by the `expected_keepers.go` shim: the hub keeper
+INTERFACE exists in P3 (in `x/partner/types/expected_keepers.go`); the real
+hub keeper impl is wired in P4. This is the ibc-go convention for breaking
+cross-module dep cycles and lets P3 ship before P4 without a forward struct
+dependency.
+
+### v0.5 Interface Contracts (6 cross-component — extended, not replaced)
+
+The six cross-component interfaces (Standing, Forge/Fold, Mirror, Window,
+Fee Covenant, Voice/Council) are EXTENDED at runtime in v0.5 (they were
+skeleton-only in v0.3):
+
+- **Window Lifecycle Interface** — `x/services` handlers check the
+  Window status on every operation (not just registration); a revoked
+  Window invalidates the service (A-552).
+- **Fee Covenant Interface** — `x/exit`/`x/bridge` exit-fee-bps fields
+  are clamped by the Fee Covenant ceiling/floor at runtime (the v0.3
+  field was typed but the Clamp was not invoked; v0.5 invokes it).
+- **Voice/Council Interface** — `x/council` gains the `Proposal`/
+  `VoteOption` enums + Voice lifecycle handlers; the `TallyResult`
+  `NoWithVeto` field (v0.2 zero-locked) is now populated by Watcher
+  Vetos (quorum-based, not single-veto).
+- **Watcher Attestation** — `x/bridge` `Attested` state is driven by a
+  Watcher quorum via the `WatcherKeeper` expected-keeper shim; `x/council`
+  Veto authz uses the same shim.
+- **Standing API** — `x/hub` compliance service checks a partner's
+  Standing by reach-id at runtime (the v0.3 by-ID-string field becomes a
+  query).
+- **Forge/Fold** — unchanged in v0.5 (no forge/fold runtime promotion this
+  milestone).

+## v0.3 Final Audit (P6)
+
+### Reconstruction Test — **PASS**
+
+**Git log matches `.ciagent/` files.** `git log v0.1.5..HEAD --oneline` returns 13 commits across P0-P5 (6 phase-ship `docs(P##):` commits, 5 `checkpoint(P##):` advance commits, 1 v0.2 milestone marker inherited via v0.1.5). The 6 `docs(P##): complete ...` commits each carry a `---ci---` block with `status: complete` and the correct phase integer.
+
+**Per-phase `---ci---` block verification:**
+
+| Phase | Commit | Tag | `status` | `requirements.covered` | `requirements.partial` | Verdict |
+|---|---|---|---|---|---|---|
+| P0 | 23de3c5 | v0.2.0 | complete | [] (pre-execution) | [] | PASS |

+
+- Phase `---ci---` blocks: 6 (one per phase P0-P5). Each phase's final block shows `status: complete`. ✓
+- Tag count: 6 (v0.2.0..v0.2.5). Each tag exists and points at the matching `docs(P##): complete ...` commit. ✓
+- REQ coverage vs. expected (P0: none; P1: REQ-028; P2: partial REQ-027; P3: REQ-027; P4: REQ-010/022/023; P5: REQ-024/025/026): **exact match on all 6 phases**. ✓
+- IDEATE traceability (REQUIREMENTS.md §"IDEATE Traceability"): 8 IDEATE-NN → REQ-ID mappings present (IDEATE-01→REQ-027 ... IDEATE-08→REQ-026). ✓
+- CHECKPOINT.json matches state: `phase: 5`, `stage: complete`, `milestone: v0.3`, `tag_base: v0.2.x`, `milestone_complete: false`, `phase_release_tag: v0.2.5` — consistent with "P5 complete, advancing to P6 final review/audit/ship". ✓

+
+**Stale-content fixes applied during this audit:**
+- REQUIREMENTS.md v0.3 table: all 8 REQs were marked `Pending` despite P1-P5 shipping them. Updated REQ-010/022/023/024/025/026 → `Skeleton`, REQ-027/028 → `Complete` to match the `---ci---` coverage blocks.
+- ROADMAP.md v0.3 milestone: header read `ACTIVE` with no per-phase completion markers; P0-P5 shipped. Added `[x]` markers for P0-P5 and `[ ]` for P6-in-progress, plus a status line.
+
+No orphan files detected. REVIEW.md exists (v0.2 content; review agent may append v0.3 section concurrently — tracked as pending, non-blocking).
+
+**File discipline verdict: PASS** (after REQUIREMENTS + ROADMAP freshness fixes).

+# Audit: OpenYield (oy) — v0.4 (Refinement — NFR) Final Phase
+
+> **Auditor**: CIAgent security-auditor (read-only on source; writes only to `.ciagent/`)
+> **Date**: 2026-08-17
+> **Target**: v0.4 milestone (main..oy/milestone/v0.4-refinement) + `.ciagent/oy/` files
+> **Milestone**: v0.4 — Refinement (NFR)
+> **Autonomy**: full
+
+## 1. Reconstruction Test (git log ↔ `.ciagent/` files)
+
+### 1.1 Phase progression
+
+The v0.4 milestone progresses through 5 phases, each with a `---ci---` block and a tag:
+
+| Phase | Stage commits | Tag | Release ID | `.ciagent/` evidence |
+|-------|---------------|-----|-----------|----------------------|
+| P0 (pre-execution) | specify→clarify→research→plan→grill→mvp_ux_check→complete | v0.3.0 | 748 | PROJECT.md v0.4 section, REQUIREMENTS.md v0.4 table, ARCHITECTURE.md v0.4 section, PERSONAS.md v0.4, PLANS.md v0.4 plan, GRILL.md v0.4 section |
+| P1 (lexicon+const) | execute→verify→complete | v0.3.1 | 749 | REVIEW.md (P1), `lexicon/lexicon.go` helper, `x/hub/types/cross_const_test.go` |
+| P2 (lifecycle docs) | execute→verify→complete | v0.3.2 | 750 | ARCHITECTURE.md divergence section, `x/council/types/types_test.go` intent test |
+| P3 (docs CI) | execute→verify→complete | v0.3.3 | 751 | `.gitea/workflows/docs-build.yml`, `.gitignore` site/ |
+| P4 (final review+ship) | in progress | v0.3.4 (pending) | — | this AUDIT.md section + REVIEW.md v0.4 section |
+
+Reconstruction: the git log subject lines match the `.ciagent/` file state. Each phase's `---ci---` block is present in the commit messages. Tags v0.3.0..v0.3.3 exist. **PASS.**
+
+### 1.2 `.ciagent/` file discipline
+
+14 files in `.ciagent/oy/` (ARCHITECTURE, AUDIT, GRILL, P1-P4_SHIP_VERIFICATION [P1-P3 from v0.2/v0.3, P4 pending], PERSONAS, PLANS, PROJECT, REQUIREMENTS, RESEARCH, REVIEW, ROADMAP). All present and updated for v0.4. CHECKPOINT.json reflects the current phase. config.json has `milestone: v0.4`, `milestone_type: nfr`, `tag_base: v0.3.x`. **PASS.**
+
+### 1.3 Branch hygiene
+
+Local: `main`, `oy/milestone/v0.4-refinement`, `oy/phase/04-final-review-ship` (current). Remote: `origin/main`, `origin/oy/milestone/v0.4-refinement`. All merged execution phase branches (P1, P2, P3) deleted locally. No leftover phase branches. The P4 final phase branch will be deleted at milestone ship. **PASS.**
+
+### 1.4 Commit discipline
+
+All 20 milestone commits have `---ci---` blocks with `project: oy`, `phase: N`, `milestone: v0.4`, `status: <stage>`, `tag_base: v0.3.x`, `milestone_type: nfr`. Commit subjects use conventional prefixes (docs, refactor, test, chore, verify, decision, checkpoint, Merge). No `feat:` subjects. **PASS.**
+
+### 1.5 Build / test / coverage sanity
+
+- `go build ./...`: clean.
+- `go test ./...`: green (26 packages, all ok).
+- `go vet ./...`: clean on touched packages.
+- Coverage: `x/hub/types` 93.3% (v0.3 floor preserved; new cross-const test adds coverage). `x/council/types` 96.4% (improved from v0.3). Both above the 80% target (D-033). `go.mod` unchanged (zero deps, G-006). **PASS.**
+
+## 2. NFR Purity Gate (v0.4 mandatory)
+
+The NFR purity gate (D-047, D-001 filter) requires zero `feat:` commits in the v0.4 milestone range. The gate is checked on COMMIT SUBJECTS (not bodies), because `git log --grep` over-matches commit bodies that mention "feat:" in prose (e.g., the verify commits say "zero feat: commits in P2" in the body).
+
+**Gate command**: `git log --format="%s" main..HEAD | grep -E "^feat:"`
+
+**Result**: exit 1 (zero matches). The 20 commit subjects are: `docs(init)`, `docs(P00)` ×3, `docs(P00)` grill, `decision(P00)`, `Merge` ×3, `refactor(lexicon)`, `verify(P1)`, `checkpoint(p1)` ×3, `docs(arch)`, `verify(P2)`, `checkpoint(p2)`, `chore(ci)`, `verify(P3)`, `checkpoint(p3)`. None start with `feat:`.
+
+**NFR purity gate: GREEN.** ✓
+
+## 3. Non-Critical Observations (P1+ flags, not blocking)
+
+### P2-1: mkdocs build warnings (pre-existing v0.3 docs links)
+- **Files**: `docs/index.md`, `docs/shared/vision.md` (link to `../README.md` / `../../README.md`)
+- **Note**: `mkdocs build` produces 2 warnings about README.md not being in the docs tree. The build SUCCEEDS (warnings, not errors). These are pre-existing v0.3 docs content links, NOT introduced by v0.4. v0.4's REQ-032 is the CI workflow (which runs `mkdocs build` and succeeds despite the warnings), not the docs content.
+- **Recommendation**: post-hoc fix in v0.5+ (either include README.md in mkdocs nav, or fix the relative links). Not a v0.4 ship blocker.
+
+### P2-2: Gitea Actions `actions/upload-artifact@v4` compatibility
+- **File**: `.gitea/workflows/docs-build.yml`
+- **Note**: the workflow uses `actions/upload-artifact@v4`. Gitea Actions (which reimplements GitHub Actions) supports most `actions/*` but v4 of upload-artifact has had compatibility quirks. If the upload step fails, the `mkdocs build` step (the higher-priority check) would still have succeeded.
+- **Recommendation**: post-hoc verify on the first real CI run; downgrade to v3 or use Gitea-native upload if needed. Not a ship blocker (the build is the gate, the artifact is a bonus).
+
+### P2-3: NFR purity gate precision (documented in REVIEW.md P1+ #3)
+- **Note**: `git log --grep "^feat:"` over-matches commit bodies. The audit uses the subject-only gate (`--format="%s" | grep -E "^feat:"`). This is documented for future milestones.
+- **Recommendation**: bake the subject-only gate into the next milestone's PLAN. Not a ship blocker.
+
+## 4. Overall Audit Verdict
+
+### **PASS**
+
+The v0.4 (Refinement — NFR) milestone is **shippable**.
+
+**Per-check summary:**
+
+| # | Check | Verdict |
+|---|-------|---------|
+| 1.1 | Reconstruction (phase progression, tags, `.ciagent` evidence) | PASS |
+| 1.2 | `.ciagent` file discipline (14 files, CHECKPOINT, config.json) | PASS |
+| 1.3 | Branch hygiene (no leftover phase branches; P4 final pending) | PASS |
+| 1.4 | Commit discipline (`---ci---` blocks; conventional subjects; no feat:) | PASS |
+| 1.5 | Build / test / coverage sanity (build, test, ≥80%, lexicon, G-006) | PASS |
+| 2 | **NFR purity gate** (zero `feat:` commit subjects) | **GREEN** |
+
+**Critical issues: 0.**
+**Non-critical observations: 3** (all P2, post-hoc, non-blocking).
+**Confidence in overall verdict: 0.90.**
+
+## STRIDE security summary (per ci-auditor role, read-only)
+
+| Category | Finding | Severity | Disposition |
+|---|---|---|---|
+| Spoofing | No auth surface added (v0.4 is refactor+test+docs+CI; no new identity logic) | Low | Accept |
+| Tampering | The cross-const test (REQ-030) HARDENS tamper-resistance: a future change to `x/bond.CouponCapBps` or `x/hub.LendingCouponCapBps` is now detected by an automated test (was comment-only before v0.4). The absolute-value assertion (G-015) catches paired drift. Mission Lock (8%/0%) is MORE defended after v0.4. | Low (improved) | Accept |
+| Repudiation | No audit-log changes in v0.4 | Low | Accept |
+| Info Disclosure | The CI workflow (REQ-032) does NOT publish (build+artifact only, D-051); no secret exposure in the workflow YAML; `GITEA_TOKEN` is resolved via `resolveSecret()` from `.ciagent/.env.secrets` for release creation, never via shell-env `curl` | Low | Accept |
+| Denial of Service | No network surface added; the CI workflow runs on push but does not expose a service | Low | Accept |
+| Elevation of Privilege | No privilege surface added; the lexicon helper is a pure function; the regression guard only asserts existing consts | Low | Accept |
+
+No threat exceeds the low/accept threshold. No escalations. v0.4 hardens the mission-locked const firewall (REQ-030) and the lexicon firewall (REQ-029) without introducing any new attack surface.

+## Grill Review: OpenYield (oy) — v0.4 (Refinement — NFR) Phase 0
+
+> **Reviewer**: CIAgent adversarial grill (red-team, full autonomy)
+> **Date**: 2026-08-17
+> **Target**: Phase 0 artifacts (PROJECT.md v0.4 section, REQUIREMENTS.md v0.4 table, ARCHITECTURE.md v0.4 section, PERSONAS.md v0.4, PLANS.md v0.4 plan, config.json) + v0.3 codebase baseline
+> **Milestone**: v0.4 — Refinement (NFR)
+> **Autonomy**: full (decision_confidence_threshold = 0.60)
+> **Mode**: multi-project (slug `oy`)
+
+### Methodology
+
+Each of nine axes was scored against concrete evidence. The v0.4 scope is small (4 REQs, 12 tasks, 5 phases including P0+P4) so the grill is correspondingly focused. The central question: **is v0.4 a legitimate NFR milestone or is it a scope-creep / busywork milestone that should be a single patch or deferred?**
+
+### Evidence baseline (verified against the actual repo)
+
+- v0.3 milestone COMPLETE: checkpoint `milestone_complete: true`, release `v0.2.6` (id 739), HEAD on `main`. Verified.
+- v0.3 forward-references for v0.4 scope: REVIEW.md P2 (A-304 cross-const), AUDIT.md §193 (P1-1/P1-2 council divergences, P2 bearers no-op), GRILL.md G-014 (lexicon helper). Verified — all four REQ-029..REQ-032 map to a real v0.3 forward-reference.
+- The two synthetic self-test tables are byte-identical duplicates: `lexicon_meta_test.go:93-104` and `lexicon_meta_docs/lexicon_meta_docs_test.go:157-168`. Verified by diff — G-014 drift risk is REAL, not theoretical.
+- `x/hub/types/types.go:51,56` defines `LendingCouponCapBps = uint32(800)` and `LendingCouponFloorBps = uint32(0)`; `x/bond/types/types.go:21,26` defines `CouponCapBps = 800` and `CouponFloorBps = 0`. No automated cross-check exists (only a cross-doc comment). Verified — A-304 drift risk is REAL.
+- `SignalKindCount = 4` is already a locked-const test (`x/council/types/types_test.go:102`). The AUDIT P1-2 rationale (Freeholder is eligibility, Guild is council tier, Capital is committed-capital) is in AUDIT.md but NOT in ARCHITECTURE.md. Verified — the documentation gap is REAL.
+- No `.github/workflows/` and no `.gitea/workflows/` directory exists. Verified — REQ-032 is net-new CI, not a modification.
+
+### Forcing Questions and Verdicts
+
+**1. Is v0.4 a legitimate milestone, or should these fixes be a single v0.3.x patch?**
+The four fixes are independent (lexicon helper, cross-const test, lifecycle docs, CI). Bundling them into a milestone with per-phase ship (P1..P3 each ship a patch) gives each fix its own release tag and audit trail. The alternative (one v0.3.1 patch with all four) loses the per-fix release boundary. D-052 phase ordering keeps each phase independently shippable. **Verdict: legitimate milestone** — the per-phase ship cadence (D-052) is the value, not the milestone label. Confidence 0.82.
+
+**2. Does REQ-031 violate the D-001 refinement-only filter by documenting a divergence that mentions `Proposal`/`VoteOption` (which are `feat:`-class types)?**
+No. DOCUMENTING a deferred `feat:` in ARCHITECTURE.md is `docs`, not `feat:`. REQ-031 adds NO enum types and changes NO locked consts. The regression-guard test asserts the CURRENT shape (4-signal) is intentional — it does not ADD a type. The D-001 filter rejects the `feat:` (adding Proposal/VoteOption) but accepts the `docs` (documenting why they are absent). **Verdict: passes D-001**. Confidence 0.85.
+
+**3. Does REQ-030's test-only import of `x/bond/types` into `x/hub/types` violate G-003?**
+No. G-003 forbids PRODUCTION cross-module struct imports. The import is in `x/hub/types/cross_const_test.go` (a `_test.go` file). The v0.2 GRILL G-003 explicitly documented the test-import exemption (and `x/bearers/types/types_test.go:7` already imports `x/processing/types` as a test-only precedent). The plan's P1-02-01 verification includes a grep confirming no PRODUCTION `.go` file in `x/hub/types/` imports `x/bond/types`. **Verdict: G-003 intact**. Confidence 0.88.
+
+**4. Does REQ-032 (CI workflow with mkdocs) violate G-006 (zero Go deps)?**
+No. The CI workflow installs mkdocs + mkdocs-material in a SEPARATE CI job (`docs-build`), not in `go.mod`. `go.mod` is not modified by the workflow (Python deps are isolated to the CI runner). The plan's P3-99-01 verification confirms `go.mod` diff is empty. **Verdict: G-006 intact**. Confidence 0.90.
+
+**5. Is the NFR purity gate enforceable?**
+Yes. The gate is `git log --grep "^feat:" <milestone-range>` returns zero. The v0.4 plan explicitly rejects `feat:`-class work (D-050 rejects Proposal/VoteOption; D-051 rejects Pages publish as a feature). The P4 audit (P4-02-01) runs the gate. The only risk: a commit MESSAGE accidentally using `feat:` prefix — the gate checks the prefix, not the content. **Verdict: enforceable**. Confidence 0.85.

+
+## Methodology
+
+v0.5 is the first milestone to ship executable behavior beyond invariant tests: 8
+v0.3 skeleton modules are promoted to live keeper `MsgServer` handlers + simtest.
+This is a load-bearing change of the project's character: `go.mod` gains
+`cosmos-sdk` + `ibc-go` (D-055 — the first break of G-006), `types/` packages gain
+`sdk.Msg` imports (the first break of the v0.1-v0.4 zero-dep `types/` property),
+and keeper-to-keeper cross-module calls appear (a NEW G-003 surface). The grill
+treats each of these as a forcing question, not a narrative.
+
+### Evidence baseline (verified against the actual repo, not the docs)
+
+- `go.mod`: `module github.com/oy/openyield`, `go 1.22`, **zero dependencies**
+  (confirmed — no require lines). D-055 will make cosmos-sdk the FIRST external
+  Go dep in the project's history. This is a one-way door for `go.mod` hygiene.
+- `x/` module count: **29 entries** under `x/` (one is `README.md`; 28 actual
+  modules — verified). The 8 v0.5 targets (exit, bridge, bearers, partner, hub,
+  services, bond, council) all exist as `types/`-only packages from v0.3.
+- **Zero cosmos-sdk imports** in `x/` today (grep `cosmos-sdk|cosmos/cosmos|
+  sdk.Context` → empty). v0.5 P1-01-01 introduces the first.
+- **Empty `keeper/` subdirs exist for 5 v0.1 baseline modules** (`x/mirror/keeper`,
+  `x/forge/keeper`, `x/still/keeper`, `x/watcher/keeper`, `x/bread/keeper`) —
+  all EMPTY (no `.go` files). RESEARCH §1.1 says "there is NO `keeper/` subdir"
+  for the v0.3 targets, which is correct; but the claim "NO `keeper/` subdir
+  anywhere" is imprecise — v0.1 baseline has empty keeper dirs. Not blocking, but
+  the v0.5 "promote to runtime" pattern should NOT touch the 5 v0.1 baseline
+  keepers (out of scope; D-056 scopes P1..P7 to the 8 v0.3 modules). **Noted.**
+- **G-003 import-invariant test** exists: `x/window/types/types_test.go` scans
+  non-test `x/**/*.go` via `go/parser`. **Confirmed: zero cross-module struct
+  imports in production x/ today** (`grep -rn "openyield/x/" x/ --include="*.go"
+  | grep -v "_test.go"` → empty). The v0.5 `expected_keepers.go` shims must keep
+  this green (interfaces, not struct imports).
+- **Locked consts verified present and unchanged**:
+  - `x/bond/types/types.go:21,26`: `CouponCapBps = 800`, `CouponFloorBps = 0`
+    (D-028).
+  - `x/bond/types/types.go:239`: `ClampGrowth` has the **G-012 guard**
+    (`if currentBps >= CouponCapBps { return 0 }`) — the v0.3 grill fix landed.
+  - `x/council/types/types.go:25`: `MissionLockAmendable = false`.
+  - `x/council/types/types.go:30`: `SignalKindCount = 4`.
+  - `x/partner/types/types.go:18`: `PartnerTierCount = 4`.
+  - `x/hub/types/types.go:42,51,55`: `HubServiceCount = 3`,
+    `LendingCouponCapBps = uint32(800)`, `LendingCouponFloorBps = uint32(0)`.
+- **Proposal / VoteOption / ProposalStatus / WatcherVetoQuorum ABSENT** from
+  `x/council/types` today (correct — P7 adds them). `TallyResult.NoWithVeto`
+  field EXISTS (`types.go:142`) with an explicit comment "always 0 — no veto
+  option (anti-greed)".
+- **CRITICAL FINDING (feature purity gate)**: `x/council/types/types_test.go:233-
+  239` contains `TestTallyResultNoWithVetoAlwaysZero` which asserts
+  `tr.NoWithVeto != 0` → error "expected 0 (no veto option — anti-greed)". v0.5
+  P7 (D-060, ARCHITECTURE.md v0.5 Voice/Council Interface, RESEARCH §2.7)
+  **populates `NoWithVeto` with Watcher Vetos** ("the v0.2 `NoWithVeto` field,
+  zero-locked in v0.2, is now populated by Watcher Vetos"). This is a
+  **contradiction**: the v0.2 regression test says NoWithVeto is ALWAYS 0
+  (anti-greed); the v0.5 plan says NoWithVeto is populated by Vetos. The plan
+  lists P7-03-01 as extending `types_test.go` but does NOT call out that
+  `TestTallyResultNoWithVetoAlwaysZero` must be REPLACED, not extended. This is a
+  breaking change to a locked-invariant test that the feature purity gate
+  ("no breaking schema changes") must reconcile. **Binding fix G-017** (below).
+- **Cross-const test** (REQ-030/G-015) exists at `x/hub/types/cross_const_test.go`
+  with `TestConstsAreMissionLocked800And0` asserting absolute 800/0 (G-015
+  landed). The v0.5 P4 lending clamp must keep this green.
+- **Both lexicon firewalls** present (`lexicon_meta_test.go`,
+  `lexicon_meta_docs/lexicon_meta_docs_test.go`).
+- **git history**: v0.4 milestone COMPLETE (`4369b3e checkpoint(milestone): v0.4
+  complete`). HEAD on `phase/00-pre-execution` off `milestone/v0.5-bearers-
+  runtime`. P0 for v0.5 is in progress (PLAN committed at `a0145e4`).
+
+These baseline facts confirm the v0.5 plan's architecture claims against the
+actual codebase, with one material contradiction (the NoWithVeto regression test
+vs. the P7 Veto population).

+
+## 1. Decision Ratifications (D-055, D-062, D-063, D-064, D-065)
+
+### D-055 — cosmos-sdk + ibc-go dep as G-006 controlled exception
+
+**Verdict: RATIFY (confidence 0.82)**
+
+**Evidence**: `go.mod` is zero-dep today (verified). The v0.3 skeleton keepers
+are in-memory `map[string]T` stubs (verified: `x/partner/types/types.go` Keeper
+stub). Promoting to `MsgServer` (`sdk.Msg`, `sdk.Context`, `sdk.KVStore`,
+`RegisterServices`) is impossible without cosmos-sdk — hand-rolling store +
+message routing would duplicate the SDK and is the rejected alternative in
+D-055's rationale. The exception is genuinely scoped: runtime phases P1..P7
+import cosmos-sdk; P0 (this PLAN) and P8 stay dep-neutral; `types/` packages
+gain `sdk.Msg` imports isolated in `types/msg_*.go`. The G-006 *intent*
+(durability of skeleton types) is preserved by keeping the v0.3 `types/` contract
+structs/enums/consts unamended — runtime adds behavior on top (D-054).
+
+**One caveat**: the `types/` packages losing zero-dep status is a one-way door.
+Once `x/bond/types` imports cosmos-sdk for `Msg*`, the v0.1-v0.4 property
+"`types/` compiles with stdlib only" is gone. RESEARCH §3.1 acknowledges this and
+isolates `Msg*` to `types/msg_*.go`. The invariant/lexicon tests in `types/`
+MUST stay stdlib-only and green (they don't need `Msg*`). **Binding fix G-017
+family** (below) does not block D-055 but records the constraint: P1-01-01 must
+add a CI assertion that invariant/lexicon tests pass WITHOUT the cosmos-sdk
+build tag (or that they remain in stdlib-only `_test.go` files that don't import
+`sdk.Msg`). Confidence holds.
+
+### D-062 — cosmos-sdk v0.50.x + ibc-go v8.x version pin
+
+**Verdict: RATIFY (confidence 0.80)**
+
+**Evidence**: cosmos-sdk v0.50.x is the LTS line compatible with go 1.22
+(RESEARCH §3.1, A-504). ibc-go v8.x is the stable pairing for v0.50
+(Osmosis/dYdX-v4 lineage). The alternative (ibc-go v10 / IBC v2 Eureka) is newer
+and risks churn in a runtime-promotion milestone; the v0.5 impl uses the v8
+stable `OnRecvPacket`/`OnAcknowledgementPacket`/`OnTimeoutPacket` contract
+(ARCHITECTURE.md v0.5 IBC Packet Handler Scope). The RESEARCH §2.1 Eureka
+timestamp-only-timeout pattern is DOCUMENTED but the v8 interfaces suffice for
+the 5 locked L2 chains (D-059). Pinning v8 now and upgrading to v10 in a later
+milestone is lower-risk than pinning v10 in a milestone whose primary goal is
+runtime promotion, not IBC-v2 migration.
+
+**One caveat**: cosmos-sdk v0.50.x and ibc-go v8.x have large transitive dep
+trees (hundreds of modules). P1-01-01 (`go mod tidy`) will produce a `go.sum`
+that is orders of magnitude larger than the zero-dep baseline. This is
+expected and acceptable (D-055 ratifies), but the P1-99-01 verification must
+confirm `go build ./...` succeeds under go 1.22 with the new tree (a
+transitive dep requiring go 1.23+ would block). The plan's P1-01-01 verification
+says "go version compatible (go 1.22+)" — **binding fix G-018** makes this a
+HARD gate: if `go build ./...` fails under go 1.22, P1 does not ship (escalate
+to a go version bump, which is out of scope for v0.5). Confidence holds.
+
+### D-063 — Bond CLOB match above 800 bps = REJECT (fails closed)
+
+**Verdict: RATIFY (confidence 0.78)**
+
+**Evidence**: D-057 says "hard clamp on each match"; the runtime interpretation
+(D-063) is REJECT above cap. The rationale is sound: the 8% cap is a Mission-
+Lock invariant (D-028), not a soft cap. A match above 800 bps is a usury
+violation, not a clampable excess. REJECT fails closed (the resting order
+stays; the incoming order rests or is cancelled) — no refund path, no
+partial-clearing ambiguity. The Fee Covenant `Clamp` shape (clamp, not reject)
+applies to ISSUANCE (a coupon set by the issuer), where clamping is the
+mission-lock-true choice; MATCHING is market-determined, where reject is the
+mission-lock-true choice. The distinction is defensible and documented in
+D-063's rationale.
+
+The alternative (clamp-with-refund) adds a refund path — a new state
+transition with its own failure modes (what if the refund fails? does the
+match revert?). REJECT is simpler and safer for the highest-severity locked
+const. Simtest (P6-03-01) covers the reject-above-cap case explicitly.
+
+**One caveat**: the "implied coupon" computation must be unambiguous. The
+match's implied coupon is derived from the trade price (fraction of principal
+in bps) — the plan does not specify the exact formula (price → implied coupon).
+If two implementers compute it differently, the reject threshold is
+inconsistent. **Binding fix G-019**: P6-02-01 (`clob.go`) MUST define a single
+`ImpliedCoupon(priceBps, principal) uint32` helper (or equivalent) used by
+BOTH the match and the clamp check, with a unit test covering the boundary
+(price implying exactly 800, 801, 799 bps). Confidence holds after the fix.
+
+### D-064 — MissionLockAmendment-Rejected rejected at ValidateBasic
+
+**Verdict: RATIFY (confidence 0.85)**
+
+**Evidence**: `MissionLockAmendable = false` is a v0.2 locked const
+(`x/council/types/types.go:25`, verified). `TestMissionLockAmendableConstFalse`
+and `TestMissionLockAmendableCannotBeSetTrue` (types_test.go:67-88) guard the
+const. D-064 rejects `MissionLockAmendment-Rejected` ProposalKind at
+`MsgSubmitProposal.ValidateBasic` — the message never reaches the handler. This
+is the cleanest firewall: the const is the firewall, `ValidateBasic` is the
+gate, and no state record is created for an unproposable proposal. The
+alternative (propose-then-fail) would create dead state (a Pending proposal that
+auto-transitions to Failed) — unnecessary state growth and a misleading
+on-chain record. The Mission-Lock-non-amendable design intent is
+"unproposable", not "propose-then-fail" (RESEARCH §2.7).
+
+P7-03-01 simtest asserts `MsgSubmitProposal` with the rejected kind fails
+`ValidateBasic` with a Mission-Lock error and the keeper's Proposal store is
+empty. This is a concrete, testable firewall. Confidence holds.
+
+### D-065 — Watcher Veto quorum default = 6
+
+**Verdict: RATIFY (confidence 0.78)**
+
+**Evidence**: REQ-004 fixes the Watcher quorum at 6-of-9. The Veto quorum
+mirrors it (a Watcher-coordinated veto requires the same quorum as a Watcher
+attestation). A single Veto blocking would violate the anti-greed principle
+(vision §19 — no single-actor veto gate). Defaulting to 6 as a PARAM (not a
+locked const) lets a future governance vote adjust without a Mission-Lock-class
+amendment — defensible, since Veto quorum is NOT a Mission-Lock const (the
+distinction is documented in v0.4 ARCHITECTURE.md). The `Params` struct is
+currently empty (`types.go:148` `type Params struct{}`); P7-01-01 adds
+`WatcherVetoQuorum` defaulting to 6.
+
+**Two caveats**:
+1. **Param validation**: a `WatcherVetoQuorum` param of 0 (no quorum needed —
+   any single Veto blocks) or 10 (more than the 9 Watchers — veto impossible)
+   would violate the anti-greed / REQ-004 semantics. The plan's P7-01-01 does
+   NOT specify `Params.Validate()` bounds. **Binding fix G-020**: P7-01-01 MUST
+   add a `Params.Validate()` (or `ValidateBasic` on the param) asserting
+   `WatcherVetoQuorum` is in `[1, 9]` (or `[2, 9]` to forbid single-veto-block
+   even if the param is mis-set). The default 6 is correct; the validation
+   bounds are the missing piece.
+2. **The NoWithVeto contradiction** (see G-017) is the bigger Veto concern —
+   the v0.2 regression test asserts NoWithVeto is ALWAYS 0. P7 populates it.
+   This must be reconciled regardless of the quorum value.
+
+Confidence holds after G-017 and G-020.
+
+---
+
+## 2. Nine-Axis Adversarial Scorecard
+
+### Axis 1 — Feasibility (8 modules × MsgServer + simtest at full autonomy) — **PASS** (confidence 0.80)
+
+36 tasks across 8 phases for 8 module promotions is proportionate. Each module
+gets a types+msg task, a keeper+msg_server task, a simtest task, and a
+verification task — the same 4-task vertical-slice shape, repeated. v0.3
+shipped 50 tasks / 6 phases at full autonomy and closed clean; v0.5's 36 is
+smaller. The MsgServer promotion is the standard pre-mainnet Cosmos-SDK step
+(every ibc-go/Osmosis/Celestia/dYdX module follows it). The simtest grade (D-054
+— in-memory `sdk.Context` + dbm, no real IBC/MPC/hardware) is genuinely
+achievable, not a half-finished mainnet. No axis-1 risk reaches escalation.
+
+The one feasibility risk is **cosmos-sdk v0.50.x build under go 1.22**: the
+transitive tree is large and may pull a module requiring go 1.23+. G-018
+makes this a hard P1 gate. Confidence holds.
+
+### Axis 2 — Scope (8 modules, outer→inner chain) — **PASS** (confidence 0.78)
+
+D-056's phase ordering (P1 exit+bridge → P2 bearers → P3 anchors → P4 hub → P5
+services → P6 bond → P7 council → P8 final) follows the dependency graph
+correctly: exit needs nothing internal; bearers route through exit; anchors
+ride bearers; hub custody backs anchors; services sit on hub; bond uses hub
+lending; council is cross-cutting. The P3→P4 hub dep is broken by the
+`expected_keepers.go` shim (the hub keeper INTERFACE exists in P3, impl wired
+in P4 — ibc-go convention, A-532). The out-of-scope list is explicit (no
+mainnet, no real IBC, no real MPC, no real bearer hardware, no real
+institutional onboarding — D-054). Scope is not over-scoped for a runtime-
+promotion milestone.
+
+The one scope concern: **P7 adds 3 new enums + 1 struct to `x/council/types`**
+(ProposalKind, ProposalStatus, VoteOption, Proposal). This is `feat:`-class
+new-type work (correctly deferred from v0.4 by D-050/D-001). The feature
+purity gate ("no breaking schema changes") must distinguish "adding new
+types" (allowed) from "amending existing types/consts" (forbidden). The
+`TallyResult.NoWithVeto` field is the gray area: the FIELD exists in v0.2 (zero-
+locked), v0.5 POPULATES it. Is populating an existing field a "breaking schema
+change"? No — the struct shape is unchanged; the SEMANTIC invariant
+("NoWithVeto always 0") changes. **G-017** forces the plan to reconcile the
+v0.2 regression test explicitly. Confidence holds after the fix.
+
+### Axis 3 — Cost / Effort (36 tasks, cosmos-sdk onboarding) — **CONDITIONAL** (confidence 0.72)
+
+36 tasks is proportionate to the deliverable (8 module promotions). The hidden
+cost is the **cosmos-sdk onboarding** in P1-01-01: `go mod tidy` will pull a
+large transitive tree, and the FIRST `go build ./...` with cosmos-sdk will
+surface any go-version / module-replace / cometbft-separation issues. This is
+a one-time cost concentrated in P1. If P1-01-01 takes more than 1 task's worth
+of effort (likely — cosmos-sdk dep resolution is notoriously finicky), the
+plan's single P1-01-01 task underestimates it. **Not blocking** (the task is
+scoped correctly; the risk is effort, not feasibility), but P1 may absorb
+spillover. No binding change — record the risk.
+
+The other cost driver is **simtest coverage ≥80% on 8 keeper packages**. v0.3
+hit ≥95.9% on type packages (trivial structs). Keeper packages with MsgServer
+handlers + state machines + replay/timeout logic have higher cyclomatic
+complexity; 80% is achievable but requires table-driven handler tests per
+`Msg*` (the plan specifies this). Not a cost cliff.
+
+### Axis 4 — Architecture (expected_keepers, G-003 survival, IBC contract) — **CONDITIONAL** (confidence 0.75)
+
+The G-003 by-ID-string rule survives the runtime promotion via
+`expected_keepers.go` interface shims (ibc-go convention) — verified: the
+existing G-003 import-invariant test in `x/window/types/types_test.go` scans
+non-test `x/**/*.go` and will auto-cover the new `keeper/` + `msg_*.go` +
+`expected_keepers.go` files. The shims are INTERFACES defined in the consuming
+module's `types/` (e.g., `x/exit/types/expected_keepers.go` defines
+`BridgeKeeper`); the concrete keeper satisfies it structurally. This is NOT a
+struct import — G-003 intent (no cross-module struct coupling, no import
+cycles) is preserved. Correct.
+
+Two architecture concerns:
+1. **The G-003 import-invariant test scans `x/**/*.go`** — but `expected_keepers
+   .go` defines an interface that REFERENCES another module's types by NAME in
+   comments (not imports). The test uses `go/parser` ImportsOnly, so interface
+   method signatures that mention `x/bridge` types by STRING (e.g., return
+   `(status, bridgeType, err)`) are fine; but if an implementer writes a
+   method returning `x/bridge.BridgeRoute` (a struct import) to satisfy the
+   shim, the test catches it. Good — the test is the firewall. No binding
+   change, but P8-01-01 (REVIEW) must explicitly probe this.
+2. **IBC `OnRecvPacket` / `OnAcknowledgementPacket` / `OnTimeoutPacket`
+   contract**: the plan pins the ICS-20 v1 payload shape (v0.2 satellite) and
+   timestamp-only timeouts for EVM chains (ibc-go v8 supports this). The Solana
+   wormhole-adapter branch verifies a 2-of-N guardian sig set from state. The
+   replay protection (delete-on-ack, refund-on-timeout) mirrors ibc-go (A-513,
+   the CVE-class pitfall). This is the highest-risk architecture surface in
+   v0.5. The simtest (P1-06-01) MUST cover both replay and timeout-refund
+   explicitly — the plan says it does. **Binding fix G-021**: P1-06-01 simtest
+   MUST include a NEGATIVE assertion that a SECOND `OnAcknowledgementPacket`
+   with the same packet commitment is REJECTED (not silently no-op'd) — the
+   distinction between "no-op" and "reject" matters for relayer error handling.
+   Confidence holds after the fix.
+
+### Axis 5 — Risk (top 3 assumptions, pre-mortem) — **CONDITIONAL** (confidence 0.72)
+
+**Top 3 assumptions the plan rests on:**
+1. **A-504** (cosmos-sdk v0.50.x builds under go 1.22) — confidence 0.78. The
+   dep tree is large; a single transitive module requiring go 1.23+ blocks P1.
+   G-018 makes this a hard gate. Evidence: RESEARCH §3.1 confirms go 1.22
+   compatibility for v0.50.x, but does not enumerate the transitive tree.
+2. **A-513** (IBC ack/timeout replay protection mirrors ibc-go) — confidence
+   0.90. This is the highest-severity runtime invariant (CVE-class pitfall).
+   The simtest covers it; G-021 strengthens the assertion. Evidence: RESEARCH
+   §2.1, P1-06-01.
+3. **A-521** (OY-QR one-shot: `consumed` flipped BEFORE transfer effect) —
+   confidence 0.88. The atomicity argument (SDK store is atomic per tx; a panic
+   rolls back the whole tx) is sound. Evidence: RESEARCH §2.2, P2-02-01.
+
+**Pre-mortem (12 months from now, v0.5 failed — why?):**
+- Most likely: **P1 cosmos-sdk dep resolution spirals** — `go mod tidy` pulls a
+  module requiring go 1.23+, or a cometbft/tendermint replace directive conflict
+  blocks `go build`. P1 stalls, the milestone slips. Mitigation: G-018 hard
+  gate + escalation to a go version bump (out of scope, but visible).
+- Second: **the NoWithVeto regression test (G-017) is discovered at P7, not P0**
+  — the P7 implementer finds `TestTallyResultNoWithVetoAlwaysZero` fails, does
+  not know whether to delete it (breaking a v0.2 locked-invariant test) or
+  keep it (blocking Veto population). The plan did not flag this. Mitigation:
+  G-017 forces the reconciliation NOW, with a binding fix that specifies
+  exactly how the test evolves (rename + re-scope, not delete).
+- Third: **the CLOB per-match clamp's "implied coupon" is ambiguous** (G-019) —
+  two implementers compute it differently, the reject threshold is
+  inconsistent, and the simtest passes with one formula while mainnet would
+  use another. Mitigation: G-019 forces a single `ImpliedCoupon` helper.
+
+### Axis 6 — Dependency graph (P3→P4 shim, outer→inner chain) — **PASS** (confidence 0.80)
+
+The cross-phase dependency map (PLANS.md) is complete and correct:
+- P1-01-01 (cosmos-sdk dep) blocks ALL runtime work (no `Msg*` compiles without
+  it). D-062 GRILL ratification is the gate.
+- P1-03-01 (x/bridge keeper) blocks P1-05-01 (x/exit keeper — BridgeKeeper shim
+  wired to real bridge keeper in simtest).
+- P3-01-01 (x/partner expected-keepers incl. HubKeeper shim) breaks the P3→P4
+  hub dep. P4-04-01 wires the real hub keeper to the PartnerKeeper shim.
+- P4-99-01 blocks P5-01-01 (services sit on hub) AND P6-01-01 (bond uses hub
+  lending). P5 and P6 could parallelize but config `parallelization.enabled:
+  false` — serial. Correct.
+- P6-99-01 blocks P7-01-01 (council cross-cutting, lands last).
+
+No hidden edges. The v0.1 baseline keepers (mirror/forge/still/watcher/bread)
+have EMPTY `keeper/` dirs — v0.5 does NOT promote them (out of scope). The
+expected-keeper shims reference the baseline keepers by INTERFACE (e.g.,
+`BreadKeeper.MintWrappedBread`), but the baseline keepers are empty stubs —
+the shims will be wired to STUB implementations in simtest (G-003 test
+exemption), not real keepers. This is correct for simtest grade (D-054) but
+**the plan does not explicitly state that the v0.1 baseline keepers remain
+empty stubs**. **Binding fix G-022**: P1-06-01 (and each simtest wiring a
+baseline keeper shim) MUST document that the baseline keeper is a STUB
+returning sentinels, not a real implementation — so a future agent does not
+mistakenly promote a v0.1 baseline keeper in v0.5. Confidence holds.
+
+### Axis 7 — Risk surface (CustodyKeyring, CLOB, IBC, Mission-Lock) — **PASS** (confidence 0.78)
+
+The four security-critical surfaces (PERSONAS.md security-engineer):
+1. **CustodyKeyring** (D-058): interface + in-memory `memKeyring`. Key rotation
+   via `Status` reporting active key version; no cross-block caching. Simtest
+   covers rotation. The interface boundary keeps v0.5 dep-neutral w.r.t.
+   custody vendors. Sound.
+2. **CLOB per-match clamp** (D-057/D-063): REJECT above 800 (G-019 implies-
+   coupon helper). The 8%/0% consts referenced directly (A-563, verified: the
+   v0.3 `Clamp` uses the consts). REQ-030 cross-const test stays green.
+3. **IBC replay/timeout** (A-513): delete-on-ack, refund-on-timeout. G-021
+   strengthens the replay assertion. Sound.
+4. **Mission-Lock const firewall** (D-064): `ValidateBasic` rejects
+   `MissionLockAmendment-Rejected` kind; the const + the gate are the dual
+   firewall. v0.2 `TestMissionLockAmendableFalse` stays green (verified: the
+   const is unchanged; P7 does NOT touch `MissionLockAmendable`). Sound.
+
+The risk surface is well-identified and the mitigations are concrete. The one
+gap is the NoWithVeto contradiction (G-017) — the v0.2 regression test
+`TestTallyResultNoWithVetoAlwaysZero` is a "locked-invariant test" that v0.5
+must reconcile, not silently break. This is the single most material risk the
+plan misses.
+
+### Axis 8 — Persona coverage (backend + lead + security + cosmos + mesh + data) — **PASS** (confidence 0.80)
+
+The roster is coherent:
+- **backend-engineer** spans all P1..P7 handler + simtest work (the bulk).
+- **lead-developer** owns P0 + P8 + coordination + GRILL-ratification follow-
+  through.
+- **security-engineer** (REACTIVATED) owns CustodyKeyring, CLOB clamp, IBC
+  replay, Mission-Lock firewall — the four security-critical surfaces. Correct
+  reactivation; v0.5 has higher invariant density than v0.3.
+- **cosmos-engineer** (REACTIVATED) owns MsgServer/expected-keepers/simtest
+  scaffolding — correct, since cosmos-sdk is now load-bearing (D-055).
+- **mesh-engineer** (REACTIVATED, P2 phase-specific) owns bearer session
+  lifecycle. Correct scoping (P2 only; removed after).
+- **data-engineer** (REACTIVATED, P4 phase-specific) owns hub custody state
+  (in-memory test store). Correct scoping (P4 only; removed after).
+- **ci-security-auditor** activated in P8 for the feature purity gate.
+
+Territory globs are non-overlapping (backend-engineer's `x/{exit,bridge,...}
+/**` vs cosmos-engineer's `keeper/**`, `types/msg_*.go`, `expected_keepers.go`,
+`module.go`). The overlap risk is `keeper/msg_server.go` — both backend and
+cosmos could claim it. The plan assigns cosmos-engineer to `keeper/**` and
+backend-engineer to `x/<module>/**` (which includes keeper/). This is a glob
+overlap. **Binding fix G-023**: clarify in PERSONAS.md that for v0.5,
+cosmos-engineer owns the Cosmos-convention scaffolding (`keeper/keeper.go`,
+`keeper/msg_server.go` skeleton, `module.go`, `types/msg_*.go`,
+`types/expected_keepers.go`); backend-engineer owns the handler LOGIC (the
+business rules inside `msg_server.go` methods, the simtest). This mirrors the
+v0.2 G-007 split. Warn-mode (config), non-blocking, but ambiguous. Confidence
+holds.
+
+### Axis 9 — Verification coverage (simtest, locked-const, feature purity gate) — **CONDITIONAL** (confidence 0.73)
+
+Each phase has a verification task (P1-99-01..P7-99-01) running `go build ./...
++ go test ./...` + coverage ≥80% + lexicon + G-003. The P8 audit (P8-02-01)
+runs the feature purity gate: no breaking schema changes, locked-const
+firewall intact, G-003 intact, G-006 GRILL-ratified. This is concrete.
+
+Two verification gaps:
+1. **The feature purity gate does not define "breaking schema change" precisely
+   enough for the NoWithVeto case.** Populating an existing zero-locked field is
+   a SEMANTIC change to a v0.2 locked-invariant test, but NOT a struct-shape
+   change. The gate as written ("v0.3 `types/` contracts NOT amended") would
+   pass (the struct is not amended), but `TestTallyResultNoWithVetoAlwaysZero`
+   would FAIL. The gate must be extended to "no v0.1..v0.4 locked-invariant
+   TEST is broken without an explicit, documented reconciliation". **G-017**
+   forces this reconciliation. The P8 audit (P8-02-01) must explicitly verify
+   that the v0.2 `TestTallyResultNoWithVetoAlwaysZero` is either (a) renamed and
+   re-scoped to "default is 0, but Watcher Vetos populate it" with a new test,
+   or (b) explicitly deleted with a replacement test asserting the quorum-based
+   Veto semantics. **Binding fix G-017** specifies (a).
+2. **The v0.1 baseline keeper stubs are not verified to remain empty.** The
+   feature purity gate should assert that v0.5 does NOT promote the 5 v0.1
+   baseline keepers (mirror/forge/still/watcher/bread). **G-022** records this.
+3. **The `types/` stdlib-only property is not verified.** v0.5 breaks it (by
+   design — `Msg*` needs `sdk.Msg`), but the invariant/lexicon TESTS in `types/`
+   must stay stdlib-only. **Binding fix G-024**: P1-99-01 MUST add a CI
+   assertion (or a test) that `go test ./x/<module>/types/...` passes WITHOUT
+   importing cosmos-sdk in the test files (i.e., the invariant/lexicon tests
+   remain stdlib-only; only `msg_*.go` imports `sdk.Msg`). This protects the
+   v0.1-v0.4 invariant-test durability.
+
+Confidence holds after G-017, G-022, G-024.
+
+---
+
+## 3. Feature Purity Gate Verification
+
+v0.5 is a **feature** milestone (not NFR). The gate (P8-02-01) verifies:
+
+- **At least one `feat:` phase exists**: YES — all P1..P7 are `feat` (confirmed:
+  each phase's task table header says `Type: feat`). P8 is `final`. ✅
+- **No breaking schema changes (locked-consts unchanged)**:
+  - `CouponCapBps=800` / `CouponFloorBps=0` (D-028) — unchanged (verified;
+    P6 references directly, A-563). ✅
+  - `SignalKindCount=4` — unchanged (P1-2 defensible; P7 does NOT change it;
+    `TestSignalKindShapeIntentional` stays green). ✅
+  - `MissionLockAmendable=false` — unchanged (P7 does NOT touch the const;
+    `TestMissionLockAmendableFalse` stays green). ✅
+  - `BearerTypeCount=6`, `PartnerTierCount=4`, `HubServiceCount=3`,
+    `BridgeStatusCount=4`, `ExitStatusCount=5`, `ServiceKindCount=4`,
+    `CouncilKindCount=3`, `OrderSideCount=2`, `OrderStatusCount=3` — all
+    unchanged (each phase's Must-Haves assert regression). ✅
+  - **`LendingCouponCapBps=800` / `LendingCouponFloorBps=0`** — unchanged
+    (P4 references directly; REQ-030 cross-const test stays green). ✅
+  - **New locked-consts added in P7** (per D-060): `ProposalKindCount=4`,
+    `ProposalStatusCount=5`, `VoteOptionCount=4`. These are ADDITIVE (new
+    types), not amendments to existing consts. Allowed under the feature
+    purity gate. ✅
+  - **`TallyResult.NoWithVeto` field**: the FIELD is unchanged (v0.2 shape); the
+    SEMANTIC invariant ("always 0") changes. The v0.2 regression test
+    `TestTallyResultNoWithVetoAlwaysZero` MUST be reconciled (G-017). This is
+    the gray area the gate must explicitly address. **CONDITIONAL → fixed by
+    G-017**.
+- **G-003 production firewall intact**: expected_keepers.go are INTERFACES (not
+  struct imports); the existing G-003 import-invariant test auto-covers new
+  files. P8-01-01 probes this. ✅ (with G-021 strengthening the IBC replay
+  assertion).
+- **G-006 controlled exception genuinely scoped**: cosmos-sdk + ibc-go in
+  `go.mod` (D-055/D-062), scoped to runtime phases P1..P7; P0 + P8 dep-neutral;
+  `types/` gain `sdk.Msg` in `msg_*.go` only; invariant/lexicon tests stay
+  stdlib-only (G-024). ✅ (with G-018 build gate + G-024 stdlib-test assertion).
+
+**Feature purity gate verdict: PASS WITH FIXES** (G-017, G-018, G-021, G-022,
+G-024). The gate is enforceable after the fixes land.
+
+---
+
+## 4. Binding Grill Fixes (G-017..G-024)
+
+These are **binding** — the orchestrator MUST apply them before the affected
+phase ships. Numbered G-017..G-024 (continuing from the v0.4 grill G-016).
+
+| ID | Binding Fix | Rationale | Confidence | Affects (phase / task) |
+|----|-------------|-----------|------------|------------------------|
+| **G-017** | **Reconcile the v0.2 `TestTallyResultNoWithVetoAlwaysZero` regression test with the v0.5 Veto population.** The v0.2 test (`x/council/types/types_test.go:233-239`) asserts `NoWithVeto == 0` "always" (anti-greed). v0.5 P7 (D-060) populates `NoWithVeto` with Watcher Vetos (quorum-based, D-065). The plan does NOT flag this contradiction. **Binding fix**: P7-03-01 MUST (a) RENAME `TestTallyResultNoWithVetoAlwaysZero` to `TestTallyResultNoWithVetoDefaultZero` (asserting the DEFAULT `TallyResult` has `NoWithVeto==0`, i.e., a proposal with zero Vetos has zero NoWithVeto — still true), and (b) ADD `TestTallyResultNoWithVetoPopulatedByQuorum` asserting that Watcher Vetos populate `NoWithVeto` and the proposal fails only at `NoWithVeto >= WatcherVetoQuorum` (default 6). The v0.2 anti-greed invariant ("no SINGLE-veto block") is preserved by the quorum rule; the "always 0" wording was v0.2's way of saying "no Veto option existed yet". The P8 feature purity gate (P8-02-01) MUST explicitly verify this reconciliation (the v0.2 test is not silently deleted; it is renamed + re-scoped). | The v0.2 test is a locked-invariant regression firewall. Silently breaking it at P7 violates the feature purity gate ("no breaking schema changes" extended to "no locked-invariant TEST broken without reconciliation"). The contradiction is real (verified: `types_test.go:233` asserts always 0; RESEARCH §2.7 / ARCHITECTURE.md v0.5 say NoWithVeto is populated). The fix preserves the anti-greed invariant (default 0; quorum-based population) while documenting the v0.2→v0.5 evolution. | 0.88 | **P7-03-01** (simtest + types_test.go extend); **P8-02-01** (feature purity gate must verify the reconciliation). Must land before P7 ships. |
+| **G-018** | **P1-01-01 cosmos-sdk dep is a HARD build gate under go 1.22.** `go mod tidy` + `go build ./...` MUST succeed under `go 1.22` (the `go.mod` declared version). If the cosmos-sdk v0.50.x + ibc-go v8.x transitive tree requires go 1.23+, P1 does NOT ship — escalate (a go version bump is out of scope for v0.5). P1-01-01 verification MUST assert `go version` reports 1.22+ and `go build ./...` exits 0 with no module-replace hacks for go-version conflicts. If a `replace` directive is needed for cometbft/tendermint separation, it MUST be documented in P1-01-01's deliverable. | cosmos-sdk v0.50.x is documented as go 1.22-compatible, but the transitive tree is large (hundreds of modules). A single transitive module requiring go 1.23+ blocks P1 and cascades to all P2..P7. The plan's P1-01-01 verification says "go version compatible" — this makes it a HARD gate, not advisory. | 0.82 | **P1-01-01** (go.mod + go.sum). Must land before P1 ships. |
+| **G-019** | **P6-02-01 (`x/bond/keeper/clob.go`) MUST define a single `ImpliedCoupon(priceBps, principal) uint32` helper (or equivalent) used by BOTH the CLOB match and the per-match clamp check.** The "implied coupon" derivation from trade price (fraction of principal in bps) is not specified in the plan. If two implementers compute it differently, the D-063 REJECT threshold (above 800) is inconsistent. The helper MUST have a unit test covering the boundary: price implying exactly 800, 801, 799 bps (reject at 801, clamp at 800, pass at 799). | D-063 ratifies REJECT above 800, but the "implied coupon" formula is the unstated precondition. A latent ambiguity in the highest-severity locked-const clamp is a real defect. A single helper + boundary test closes it. | 0.80 | **P6-02-01** (clob.go). Must land before P6 ships. |
+| **G-020** | **P7-01-01 MUST add a `Params.Validate()` (or `ValidateBasic` on the param) asserting `WatcherVetoQuorum` is in `[1, 9]` (recommended `[2, 9]` to forbid single-veto-block even if the param is mis-set).** The default 6 (D-065) is correct; the validation bounds are the missing piece. A param of 0 (any single Veto blocks) or 10 (veto impossible — more than 9 Watchers) would violate REQ-004 / anti-greed semantics. The v0.2 `Params` struct is empty (`types.go:148`); P7-01-01 adds the field + MUST add the validation. | D-065 ratifies the default 6 but does not bound the param. An unbounded param is a governance footgun: a future vote could set 0 (single-veto-block, violating anti-greed) or 10 (veto impossible). Validation bounds are the standard Cosmos-SDK `Params.Validate` pattern. | 0.78 | **P7-01-01** (Params + Validate). Must land before P7 ships. |
+| **G-021** | **P1-06-01 (`x/bridge` simtest) MUST include a NEGATIVE assertion that a SECOND `OnAcknowledgementPacket` with the same packet commitment is REJECTED (returns an error), not silently no-op'd.** The distinction between "no-op" and "reject" matters: ibc-go returns an error on a duplicate ack (the relayer sees the failure and does not retry); a silent no-op could mask a relayer bug. The simtest MUST assert the second ack returns a non-nil error. | A-513 mandates replay protection (delete-on-ack, reject-on-second). The plan says "reject on second" but the simtest verification says "deletes the in-flight record on first ack and rejects the second" — the "reject" must be an ERROR, not a silent no-op. A silent no-op is the CVE-class pitfall (the relayer cannot distinguish a bug from idempotency). | 0.80 | **P1-06-01** (bridge simtest). Must land before P1 ships. |
+| **G-022** | **Each simtest wiring a v0.1 baseline keeper shim (BreadKeeper, WatcherKeeper, WindowKeeper, VaultKeeper, StandKeeper) MUST document that the baseline keeper is a STUB returning sentinels, NOT a real implementation.** v0.5 promotes 8 v0.3 modules; the 5 v0.1 baseline keepers (mirror/forge/still/watcher/bread) remain EMPTY stubs (verified: their `keeper/` dirs are empty). The expected-keeper shims reference baseline keepers by interface; in simtest they are wired to STUB impls (G-003 test exemption). The P8 feature purity gate MUST assert the 5 v0.1 baseline keepers are NOT promoted in v0.5 (no new `.go` files in their `keeper/` dirs). | The plan does not explicitly state the baseline keepers remain stubs. A future agent might "helpfully" promote a baseline keeper while wiring a shim, breaking the v0.5 scope boundary (D-056 scopes P1..P7 to the 8 v0.3 modules). Documenting the stub expectation + a P8 gate assertion prevents scope creep. | 0.75 | **P1-06-01, P2-03-01, P3-03-01, P5-03-01, P6-03-01, P7-03-01** (all simtests wiring baseline keeper shims); **P8-02-01** (feature purity gate asserts baseline keepers unchanged). Must land before each simtest phase ships; P8 gate before milestone ship. |
+| **G-023** | **Clarify `keeper/msg_server.go` ownership between backend-engineer and cosmos-engineer in PERSONAS.md.** Both personas' territory globs overlap on `keeper/**` (cosmos-engineer's explicit list) and `x/<module>/**` (backend-engineer's glob, which includes `keeper/`). **Binding fix**: for v0.5, cosmos-engineer owns the Cosmos-convention SCAFFOLDING (`keeper/keeper.go` skeleton, `keeper/msg_server.go` method signatures, `module.go`, `types/msg_*.go`, `types/expected_keepers.go`); backend-engineer owns the handler LOGIC (the business rules inside `msg_server.go` method bodies, the simtest). This mirrors the v0.2 G-007 split (Cosmos-mirroring vs bespoke modules). Warn-mode (config), non-blocking, but ambiguous. | Territory enforcement is `warn` (non-blocking), but ambiguous ownership on the highest-effort files (`msg_server.go` method bodies) risks edit conflicts. The split mirrors v0.2 G-007 and aligns with the actual task assignments (cosmos-engineer scaffolds, backend-engineer implements logic). | 0.72 | **PERSONAS.md** (v0.5 roster). Apply before P1 begins. |
+| **G-024** | **P1-99-01 MUST add a CI assertion (or a test) that the invariant/lexicon tests in `x/<module>/types/` pass WITHOUT importing cosmos-sdk.** v0.5 breaks the v0.1-v0.4 `types/`-is-stdlib-only property by adding `sdk.Msg` to `types/msg_*.go` (D-055). The invariant tests (locked-const counts, enum round-trips) and lexicon assertions in `types/*_test.go` MUST remain stdlib-only — they should not import `sdk.Msg` or `sdk.Context`. The assertion: `grep -L "cosmos-sdk\|sdk.Msg\|sdk.Context" x/<module>/types/*_test.go` (or a `go/parser` scan) confirms the invariant/lexicon test files do not import cosmos-sdk. | The v0.1-v0.4 invariant tests are durable because they compile with stdlib only. If v0.5 silently lets an invariant test import `sdk.Msg`, the test breaks if cosmos-sdk is removed (e.g., a future skeleton revert). Keeping invariant/lexicon tests stdlib-only preserves their durability across dep changes. The `msg_*.go` isolation (RESEARCH §3.1) is the intent; G-024 makes it a tested invariant. | 0.78 | **P1-99-01** (and each phase's 99-01 verification). Must land before P1 ships; carries through P2..P7. |

+---
+
+## 5. Escalations
+
+**None.** All nine axes resolved at confidence ≥ 0.60 after the binding fixes
+G-017..G-024 are applied. No axis required escalation to the human. At full
+autonomy, the orchestrator applies the binding decisions and proceeds to P1.
+
+The single most material finding is **G-017** (the NoWithVeto regression-test
+contradiction): the v0.2 `TestTallyResultNoWithVetoAlwaysZero` test and the v0.5
+P7 Veto-population design are in direct conflict. This is not an escalation
+(the fix is mechanical: rename + re-scope the test, add a quorum-population
+test), but it is the finding most likely to cause a P7 stall if not surfaced
+now. The grill surfaces it; the orchestrator applies G-017 before P7.
+
+---
+
+## 6. Overall Verdict
+
+### **SHIP Phase 0 WITH FIXES** (confidence 0.78)
+
+The v0.5 Phase 0 plan is fundamentally sound and well-grounded: the runtime-
+promotion pattern (MsgServer + simtest, not mainnet — D-054) is the standard
+Cosmos-SDK pre-mainnet step; the 8-module scope is proportionate (36 tasks /
+8 phases); the outer→inner dependency chain (D-056) is correct; the
+`expected_keepers.go` shim convention preserves G-003; the locked-const
+firewall is intact (all v0.1..v0.4 consts unchanged; new P7 enums are
+additive). The plan's architecture claims were verified against the actual
+codebase (zero cosmos-sdk imports today; locked consts present; G-003 test
+green; ClampGrowth has the G-012 guard; cross-const test has the G-015 absolute
+assertion).
+
+The 5 decision ratifications (D-055, D-062, D-063, D-064, D-065) are all
+**RATIFIED**: the cosmos-sdk dep is necessary and scoped (D-055); the v0.50.x
++ ibc-go v8.x pin is the stable choice (D-062); REJECT above 800 is the
+mission-lock-true choice (D-063); `ValidateBasic` rejection is the cleanest
+Mission-Lock firewall (D-064); Veto quorum 6 as a param (not a const) is the
+governance-tunable choice (D-065).
+
+The 8 binding fixes (G-017..G-024) are **correctness and verification
+hardening**, not scope rework:
+- **G-017** (NoWithVeto reconciliation) — the single real contradiction; a
+  v0.2 regression test that v0.5 must reconcile, not silently break. Must
+  land before P7 ships.
+- **G-018** (go 1.22 build gate) — the cosmos-sdk dep's transitive tree is
+  the highest feasibility risk; a hard gate prevents a P1 stall from
+  cascading. Must land before P1 ships.
+- **G-019** (ImpliedCoupon helper) — the CLOB per-match clamp's unstated
+  formula; a single helper + boundary test closes the ambiguity. Must land
+  before P6 ships.
+- **G-020** (WatcherVetoQuorum validation bounds) — the param is unbounded
+  in the plan; validation bounds prevent a governance footgun. Must land
+  before P7 ships.
+- **G-021** (IBC replay reject-not-noop) — the CVE-class pitfall's simtest
+  assertion must require an ERROR, not a silent no-op. Must land before P1
+  ships.
+- **G-022** (baseline keeper stub documentation + P8 gate) — the 5 v0.1
+  baseline keepers must remain stubs; document + gate. Must land before each
+  simtest phase; P8 gate before milestone ship.
+- **G-023** (msg_server.go ownership split) — backend vs cosmos territory
+  overlap on the highest-effort files; clarify before P1. Apply before P1.
+- **G-024** (types/ invariant-test stdlib-only assertion) — the v0.1-v0.4
+  invariant-test durability must survive the cosmos-sdk onboarding; a CI
+  assertion protects it. Must land before P1 ships; carries through P2..P7.
+
+None of these rise to "RETHINK" or "REDUCE SCOPE" — the architecture, scope,
+ordering, and persona assignments are correct. Apply the 8 binding fixes and
+proceed to Phase P1.
+
+**Confidence in overall verdict: 0.78**

+    decision: RATIFY — bond CLOB match above 800 bps = REJECT (fails closed)
+    rationale: 8% cap is Mission-Lock invariant (D-028); match above cap is usury violation, not clampable excess; REJECT simpler (no refund path); G-019 ImpliedCoupon helper closes formula ambiguity

+  - id: D-064
+    decision: RATIFY — MissionLockAmendment-Rejected ProposalKind rejected at ValidateBasic

+  - id: D-065
+    decision: RATIFY — Watcher Veto quorum default = 6 (param, not locked const)

The v0.2 cosmos-engineer/security-engineer split is collapsed back into backend-engineer for v0.3 because the Cosmos-convention-alignment load is lower (no new IBC/governance/capability modules — x/bridge reuses the v0.2 satellite ICS-20 shape, x/hub is a fresh B2B scaffold). v0.3 is bespoke-type skeleton + tests work, which is backend-engineer's core territory.

This is the bulk of the milestone: the v0.3 skeletons were types + in-memory keeper stubs (verified — e.g. `x/partner/types/types.go:101 type Keeper struct{...}` with `NewKeeper()` returning `&Keeper{partners: make(map[string]Partner)}`, zero cosmos-sdk imports in `x/`). v0.5 adds `keeper/keeper.go` (store-backed), `keeper/msg_server.go` (one handler per `Msg*`), `types/msg_*.go` (`sdk.Msg` impls), `module.go` (RegisterServices), and a simtest exercising each handler against an in-memory `sdk.Context`. backend-engineer is the single persona that spans all seven runtime phases (P1..P7) plus the lexicon/locked-const regression guards that carry forward from v0.4.

Key mesh-specific invariants: (1) OY-QR is one-shot — MsgConsumeOYQR flips consumed BEFORE the transfer effect (replay rejected idempotently, A-521); (2) the surveillance-resistant const is a runtime invariant — the handler must NOT emit geolocation or sender physical location (simtest asserts the event set has NO geolocation fields, a negative test); (3) the BearerTransport interface gains a store-backed impl (the keeper acts as the transport in simtest; no hardware/RF dep, D-054).

The custody asset records are the closest thing to a data store in v0.5; there is NO real database and NO migration (the SDK in-memory store is the substrate). data-engineer's role is narrow: ensure the custody state shape (assetID → custody entry + sig ref + key version) is consistent with the CustodyKeyring interface and supports rotation. Removed after P4 (the hub runtime ships; later phases do not touch custody state shape). This mirrors the v0.3 data-engineer pattern (genesis schemas) but scoped to the P4 custody store.
+    frameworks: [Go 1.22, cosmos-sdk v0.50.x store, Go testing]
+    territory: ["x/hub/keeper/keyring_mem*.go", "x/hub/keeper/custody_state*.go"]
+    constraints: ["in-memory test store ONLY — no real database, no migration (D-054 simtest grade)", "custody state shape consistent with CustodyKeyring interface (assetID → custody entry + sig ref + key version); supports rotation", "removed after P4 (hub runtime ships; later phases do not touch custody state shape)"]
 
 deactivated:
-  - id: data-engineer
-    reason: INACTIVE for v0.3. The project has zero external deps and no database; the v0.2 data-engineer owned genesis.go schema helpers, which are a thin layer in v0.3's new modules (x/exit, x/bridge, x/hub, x/services each get a small GenesisState + ValidateGenesis following the v0.2 A-212 pattern). That work is owned by backend-engineer in v0.3 (the genesis schema is part of the skeleton type authoring, not a separate schema-design discipline). Reactivate if a future milestone adds a real store/migration.
-  - id: cosmos-engineer
-    reason: The v0.2 custom persona is NOT reactivated for v0.3. v0.3's new modules do not map onto new Cosmos SDK modules the way v0.2's did (x/gov, x/group, x/authz, x/capability, x/ibc-transfer). x/bridge reuses the v0.2 satellite ICS-20 shape (already aligned); x/hub/x/services/x/exit are bespoke B2B/service scaffolds with no direct Cosmos analog. The Cosmos-convention-alignment load drops below the threshold that justified a separate persona. backend-engineer absorbs the work.
-  - id: security-engineer
-    reason: The v0.2 custom persona is NOT reactivated for v0.3. v0.3's invariant density is lower than v0.2's (no Mission Lock, no new fee/bond clamp — the 8%/0% consts are reused unchanged from v0.2; the new locked-consts are enum counts: HubService=3, ServiceKind=4, BridgeStatus, ExitStatus). The locked-const + invariant tests are absorbed by backend-engineer's per-package test authoring. The docs firewall (lexicon_meta_docs_test.go) is frontend-engineer's territory. Reactivate in v0.4 if a new Mission-Lock-class invariant lands.
-  - id: ci-security-auditor
-    reason: Default deactivated; activate in P6 (review/ship) for the v0.3 milestone audit.
-  - id: mesh-engineer
-    reason: Still not needed in v0.3 (OY-SAT/OY-QR are type stubs only; no hardware/RF runtime). Activate in v0.4+ for real bearer runtime.
-
-custom_personas:
+  - id: frontend-engineer
+    reason: INACTIVE for v0.5. The v0.3 docs site (docs/**, mkdocs.yml) is COMPLETE; v0.5 has no UI/docs-content work. The docs build CI (REQ-032, v0.4) already covers docs-build on every push. Reactivate in v0.6+ if docs content is restructured or i18n is added.
   - id: docs-writer
-    rationale: v0.3's docs deliverable (~20-25 pages across 4 audiences per D-045) is a substantial content-authoring load distinct from the docs toolchain work. A dedicated docs-writer keeps the content-vs-toolchain boundary explicit: frontend-engineer owns mkdocs.yml/nav/theme/firewall-wiring; docs-writer owns the page content. This split means a toolchain PR (e.g., adding a markdown extension) does not entangle a content review (e.g., a nomads Reach-page rewrite), and vice versa. Distinct from frontend-engineer because content authoring (prose, audience voice, lexicon-safe phrasing) is a different skill from toolchain config (YAML, theme, nav, Go test wiring). Removed after P3 when the docs site is complete.
+    reason: INACTIVE for v0.5. Same reason as frontend-engineer — v0.3's docs-writer owned page content authoring; v0.5 has zero new docs pages. The only documentation work is the ARCHITECTURE.md v0.5 runtime section + this PERSONAS.md + RESEARCH.md, which is lead-developer/researcher architecture territory, not audience-content authoring. Reactivate if a future milestone adds docs pages.
+  - id: ci-security-auditor
+    reason: Default deactivated; activate in P8 (final review/audit/ship) for the v0.5 milestone audit and feature purity gate enforcement (no breaking schema changes; locked-const firewall intact; G-003 production firewall intact; G-006 controlled exception GRILL-ratified).

 ## Active Roster
 
-### backend-engineer
-- **Domain**: All Bearers skeleton Go modules in v0.3 — `x/exit`, `x/bridge`, `x/hub`, `x/services` (new); `x/bearers`, `x/partner`, `x/bond` (extended). Owns the D-020 skeleton+tests pattern (D-035 continues): Go types + keeper stubs + invariant tests, no live chain. Absorbs the v0.2 cosmos-engineer/security-engineer split because v0.3's Cosmos-convention and invariant density are lower.
-- **Frameworks**: Go 1.22 stdlib, Cosmos-style types (zero-dep).
-- **Territory**: `x/exit/**`, `x/bridge/**`, `x/hub/**`, `x/services/**`, `x/bearers/**`, `x/partner/**`, `x/bond/**`, `x/**/types/**`, `x/**/keeper/**`. (`go.mod` is read-only per G-006.)
-- **Constraints**: zero external deps (G-006), D-020 skeleton+tests (D-035), ≥80% coverage on new/extended packages, per-package lexicon assertion (REQ-012), by-ID-string inter-module refs (G-003), locked-const invariants (HubService/ServiceKind/BridgeStatus/ExitStatus counts + Anchor credential fields), no live chain/IBC/bearer/B2B runtime.

-### lead-developer
-- **Domain**: v0.3 phase decomposition (P1 firewall+docs foundation → P2 nomads → P3 freeholders → P4 Bearers I → P5 Bearers II → P6 review/ship), territory enforcement (warn mode), final review. Owns the cross-component dependency finding that constrains phase ordering: `x/exit`→`x/bridge` (same phase P4); `x/partner`-Anchor→`x/hub` (P4 before P5).
-- **Frameworks**: cross-cutting.
-- **Territory**: `.ciagent/**`, `**`.
-- **Constraints**: D-044 phase ordering (firewall-first; P4→P5 for Anchor→hub dep), milestone versioning (v0.3 / tag_base v0.2.x), lexicon gate on merge (REQ-012 extends to docs/), persona territory warn-mode, zero Go deps (G-006; docs build-deps allowed per D-042).
+## Phase-Persona Matrix
 
-### frontend-engineer (phase-specific: P1-P3 only)
-- **Domain**: v0.3 docs TOOLCHAIN — `mkdocs.yml` (site_name, nav, theme: material, markdown_extensions), the audience-based nav structure (nomads/freeholders/shared/reference per D-042), and the docs firewall test wiring (`lexicon_meta_docs_test.go` mirroring `lexicon_meta_test.go` with `lexicon.FindBannedTerm` + word-boundary regex + self-test table + self-exclusion, scanning `README.md` + `docs/**/*.md`). Owns the firewall landing in P1 BEFORE content (D-044 firewall-first). Removed after P3.
-- **Frameworks**: MkDocs Material, Markdown, Go testing (for the firewall test).
-- **Territory**: `docs/**` (toolchain), `mkdocs.yml`, `README.md`, `lexicon_meta_docs_test.go`.
-- **Constraints**: lexicon-clean by construction (REQ-012 extended via D-043; 10 banned terms absent from docs; "yield" banned standalone, "OpenYield" safe), audience-organized nav, ~20-25 pages total (D-045), no publishing CI in v0.3 (D-046), mkdocs.yml build-only Python dep (go.mod stays zero-dep per G-006).
-- **Removed after**: P3.
+| Phase | Personas | Work |
+|-------|----------|------|
+| P0 (pre-execution) | lead-developer (spec/clarify/research/plan/grill/mvp-ux + ship) | this file + RESEARCH.md + ARCHITECTURE.md v0.5 sections; planner-escalation items surfaced |
+| P1 (exit + bridge runtime) | backend-engineer + cosmos-engineer + security-engineer | REQ-033: `x/exit` DEX swap routing + `x/bridge` L2↔L1 IBC packet handlers (5 L2 chains, D-059); ibc-go IBCModule contract; Solana wormhole-adapter branch; replay/timeout simtest |

-### docs-writer (custom, phase-specific: P1-P3 only)
-- **Domain**: v0.3 docs CONTENT — the actual Markdown pages across the four audiences (nomads: Reach/Stash/bearers/Maps-Pay/Pacts/standing-basics; freeholders: 4-signals/Bayesian-Standing/Stands-Guilds/Councils-Voice/Bonds/Partner-spectrum; shared: Six-Principles/Bread-Scale/Storage-pools/Watchers-Mirror/Lexicon-glossary/Vision-overview; reference: architecture-index/component-map). Split from frontend-engineer so content review and toolchain review do not entangle. Removed after P3.
-- **Frameworks**: Markdown, MkDocs Material (content authoring only).
-- **Territory**: `docs/nomads/**/*.md`, `docs/freeholders/**/*.md`, `docs/shared/**/*.md`, `docs/reference/**/*.md`.
-- **Constraints**: lexicon-clean by construction (same REQ-012 extension; "real production"/"real return" not "real yield"; "Holder"/"Reach" not "account"; "Stash"/"Vault"/"Root-Pool" not "bank"/"deposit"/"savings"), audience-organized (each page in exactly one audience dir), page-count budget per D-045, no banned-term literals in page source (docs firewall scans .md directly, unlike .go fragment assembly).
-- **Removed after**: P3.
+## Constraints Carried Forward
 
-## Deactivated
+- **G-003 production firewall intact**: keeper-to-keeper cross-module calls use `expected_keepers.go` interface shims (ibc-go convention), NOT struct imports of `x/<module>/types`. The by-ID-string rule is preserved at the type level. Test-only cross-package imports remain exempt (the G-003 test exemption, used by REQ-030 in v0.4; simtest may import multiple `x/*/keeper` packages to wire shims).
+- **G-006 controlled exception (D-055)**: `go.mod` gains `cosmos-sdk v0.50.x` + `ibc-go v8.x` (GRILL-ratified). Scoped to runtime phases P1..P7; P0 + P8 stay dep-neutral where possible. `types/` packages gain `sdk.Msg` imports for `Msg*` types (isolated in `types/msg_*.go`); invariant/lexicon tests stay stdlib-only and green. Exact version pin is A-504 (planner/GRILL confirms).
+- **Locked-const invariants unchanged**: v0.5 ADDS `ProposalKind` (4) / `ProposalStatus` (5) / `VoteOption` (4) enums to `x/council/types` (AUDIT §193 P1-1 promotion, D-060) but does NOT change existing locked consts — `CouponCapBps=800` / `CouponFloorBps=0` (D-028), `BearerTypeCount=6`, `PartnerTierCount=4`, `MissionLockAmendable=false`, `SignalKindCount=4` (P1-2 defensible; v0.4 `TestSignalKindShapeIntentional` stays green), `BridgeStatusCount=4`, `ExitStatusCount=5`, `ServiceKindCount=4`, `HubServiceCount=3`, `CouncilKindCount=3`, etc. The REQ-030 cross-const test (`hub.LendingCouponCapBps==bond.CouponCapBps`) stays green.
+- **Lexicon firewall stays green**: the `lexicon_meta_test.go` (x/**/*.go) + `lexicon_meta_docs_test.go` (docs) automatically cover the new `keeper/`, `msg_server.go`, `simtest/` files. The new `Msg*` struct names are the lexicon surface — AVOID "deposit" in `x/hub` custody message names (use `MsgCustodyReceiveAsset`/`MsgCustodyReleaseAsset`, A-542); "coupon" not "interest"/"yield" in `x/bond`; "session"/"frame" safe in `x/bearers`; "veto" safe in `x/council`. Per-module lexicon assertions added to each new `keeper/` package.
+- **Simtest NOT mainnet (D-054)**: handlers exercised against in-memory `sdk.Context` + dbm in-memory store; no real IBC light clients, no real MPC, no real bearer hardware, no real DEX venues, no real Watcher attestations (all stubbed). The simtest does NOT assert front-running safety (out of scope for simtest-grade runtime; the CLOB handler is documented as NOT front-running-safe for mainnet, a Year-3+ concern).
+- **≥80% coverage on runtime packages (D-033 carries forward)**: every `keeper/msg_server.go` + simtest must hit the bar; table-driven handler tests per `Msg*`.
 
-- **data-engineer** — INACTIVE for v0.3. Zero deps + no database; the v0.2 genesis.go schema work is a thin layer absorbed by backend-engineer in v0.3's new modules. Reactivate if a future milestone adds a real store/migration.
-- **cosmos-engineer** (v0.2 custom) — NOT reactivated. v0.3's new modules do not map onto new Cosmos SDK modules (x/bridge reuses v0.2 satellite shape; x/hub/x/services/x/exit are bespoke). Cosmos-convention load drops below the threshold for a separate persona; backend-engineer absorbs.
-- **security-engineer** (v0.2 custom) — NOT reactivated. v0.3's invariant density is lower (no new Mission-Lock/fee-clamp; 8%/0% consts reused unchanged; new locked-consts are enum counts). Locked-const + invariant tests absorbed by backend-engineer's per-package test authoring; docs firewall is frontend-engineer's. Reactivate in v0.4 if a new Mission-Lock-class invariant lands.
-- **ci-security-auditor** — Default deactivated; activate in P6 (review/ship) for the milestone audit.
-- **mesh-engineer** — Still not needed (OY-SAT/OY-QR are type stubs only). Activate in v0.4+ for real bearer runtime.
+## Planner-Escalation Items (low-confidence assumptions, surfaced through the normal decision flow)
 
-## Custom Personas
+These are NOT auto-decided; the planner must resolve them before the corresponding phase lands:
 
-- **docs-writer** — v0.3's docs deliverable (~20-25 pages, D-045) is a substantial content-authoring load distinct from the docs toolchain. A dedicated docs-writer keeps the content-vs-toolchain boundary explicit: frontend-engineer owns mkdocs.yml/nav/theme/firewall-wiring; docs-writer owns page content. This split means a toolchain PR does not entangle a content review and vice versa. Distinct from frontend-engineer because prose/audience-voice/lexicon-safe-phrasing is a different skill from YAML/theme/nav/Go-test wiring. Removed after P3 when the docs site is complete.
+1. **A-504** — cosmos-sdk / ibc-go version pin (proposed: cosmos-sdk v0.50.x + ibc-go v8.x; alternative: ibc-go v10 IBC-v2/Eureka). GRILL review. Confidence 0.78.
+2. **A-562** — bond CLOB match above 800 bps: REJECT (fails closed, proposed) vs CLAMP-with-refund (D-057 says "clamp"). Resolve before P6. Confidence 0.70.
+3. **A-572** — `MissionLockAmendment-Rejected` ProposalKind: reject at `ValidateBasic` (proposed, the message never reaches the handler) vs propose-then-fail (record Pending → auto-transition Failed with event). Resolve before P7. Confidence 0.80.
+4. **A-574** — Watcher Veto quorum value (proposed default: 6, matching REQ-004 6-of-9). Resolve before P7. Confidence 0.75.
 
-## Framework Alignment
-- **Go 1.22** — backend-engineer targets Go 1.22 (`go.mod`); zero external deps (G-006).
-- **MkDocs Material** — frontend-engineer + docs-writer target MkDocs Material (D-042); build-only Python dep, NOT a Go dependency. No publishing CI in v0.3 (D-046).
+## Removal Notes
 
-## Territory Alignment
-- backend-engineer owns all `x/*` Bearers-skeleton modules (new: exit/bridge/hub/services; extended: bearers/partner/bond) + shared `types/`+`keeper/` authoring.
-- frontend-engineer owns the docs toolchain (`docs/**` config, `mkdocs.yml`, `README.md`, `lexicon_meta_docs_test.go`).
-- docs-writer owns docs content (`docs/<audience>/**/*.md`).
-- lead-developer owns `.ciagent/**` + `**` for cross-cutting coordination.
-- `go.mod` is read-only in v0.3 (G-006) — no persona may modify it; docs build-deps are allowed (D-042) but live outside `go.mod`.
-
-## Constraint Alignment
-- **Lexicon (REQ-012)** — every active persona carries it; backend-engineer asserts per test file (x/*); frontend-engineer asserts via the docs firewall (docs/* + README.md). The firewall extension is a sibling test, NOT a modification of the v0.2 meta-test (D-043).
-- **Skeleton + tests (D-020/D-035)** — backend-engineer enforces.
-- **≥80% coverage** — backend-engineer owns the gate for x/* packages.
-- **Phase ordering (D-044)** — lead-developer enforces; firewall-first (P1) before content (P2/P3); P4 (exit/bridge/bearers/partner) before P5 (hub/services/bond) for the Anchor→hub dependency.
-- **Locked-const invariants** — backend-engineer owns; HubService=3, ServiceKind=4, BridgeStatus count, ExitStatus count, Anchor credential fields, 8%/0% bond consts (reused).
-
-## Phase-Specific Personas
-- **frontend-engineer** — phase-specific to v0.3 P1-P3 (docs phases). Removed after P3; the Bearers skeleton phases (P4/P5) are pure Go (backend-engineer). Reassess at v0.4 if new docs work is queued.
-- **docs-writer** — phase-specific to v0.3 P1-P3 (docs content). Removed after P3 with frontend-engineer.
+- frontend-engineer and docs-writer were deactivated in v0.4 (no docs-content phase); they remain deactivated in v0.5 for the same reason (the docs site is complete from v0.3; the docs build CI is complete from v0.4). They will reactivate in v0.6+ if docs content is restructured or i18n is added.
+- cosmos-engineer, security-engineer, and mesh-engineer were deactivated in v0.3/v0.4 (lower Cosmos-convention / invariant density, no bearer hardware runtime); they are REACTIVATED in v0.5 because cosmos-sdk is now load-bearing (D-055), the runtime introduces new security-critical invariant surfaces (CustodyKeyring, CLOB clamp, IBC replay, Mission-Lock const firewall), and the bearer transport gets live handlers (P2).
+- data-engineer is reactivated as a P4-phase-specific persona (hub custody state, in-memory test store only) and removed after P4. This mirrors the v0.3 genesis-schema pattern but scoped narrowly to the P4 custody store.
+- ci-security-auditor is default off; activate in P8 for the final audit + feature purity gate.

+## Milestone v0.4 — Refinement (NFR) — Phase Plan
+
+### Milestone Summary
+
+- **Milestone**: v0.4 — Refinement (NFR)
+- **Type**: NFR (zero `feat:` phases by construction; D-047). Final-phase audit enforces the NFR purity gate (`git log --grep "^feat:"` on the milestone range returns zero).
+- **Tag base**: `v0.3.x` patch line. P0 ships as `v0.3.0`; execution phases `v0.3.1..v0.3.3`; final phase P4 patch `v0.3.4` IS the milestone release. No separate minor tag (D-008).
+- **Phases**: 4 execution + 1 final = 5. Phase 0 (this PLAN) is pre-execution.
+- **Depth**: refinement-only — refactor + test + docs + chore. No new production types, no new enum types, no behavioral changes. All work passes the D-001 refinement-only filter.
+- **Coverage target**: ≥80% on any modified package; do NOT reduce existing coverage (v0.3 floor is 93.3%).
+- **New modules**: ZERO. Touched files: `lexicon/lexicon.go` (add helper), `lexicon_meta_test.go` + `lexicon_meta_docs/lexicon_meta_docs_test.go` (refactor to consume helper), `x/hub/types/cross_const_test.go` (NEW test file), `x/council/types/types_test.go` (add intent test), `.ciagent/oy/ARCHITECTURE.md` (docs), `.gitea/workflows/docs-build.yml` (NEW CI).
+- **Phase ordering** (D-052): P1 lexicon+const hardening → P2 lifecycle divergence docs+guard → P3 docs build CI → P4 final review/audit/ship. P1 is firewall-first (highest-severity regression risk); each phase independently shippable (vertical slices).
+- **Personas**: backend-engineer (P1, P2 code), lead-developer (P2 docs, P3 CI, P4 review/ship). v0.3 frontend-engineer + docs-writer deactivated.
+
+### Cross-Phase Dependency Map
+
+```
+P1 (lexicon helper, cross-const test) ──► P4 (review)
+P2 (lifecycle docs + regression guard)  ─► P4 (review)
+P3 (docs build CI)                       ─► P4 (review)
+```
+
+No hard cross-phase blockers (all three execution phases are independent vertical slices). P4 depends on P1+P2+P3 completion only.
+
+### D-001 Refinement-Only Filter (governs every v0.4 task)
+
+- **Accept**: refactor, test, docs, chore, quality, architecture (drift fix only).
+- **Reject**: `add_requirement` + `feat:`-class signal (new enum type, new production type, new capability, new CLI, new distribution channel).
+- **Pre-seeded NFR REQs** (REQ-029..REQ-032) are exempt — already in REQUIREMENTS.md before PLAN.
+
+---
+
+## Phase P1 — Lexicon + Const Hardening
+
+- **Slug**: `lexicon-const-hardening`
+- **Branch**: `oy/phase/01-lexicon-const-hardening`
+- **REQs covered**: REQ-029 (lexicon shared helper), REQ-030 (cross-const test)
+- **Tag**: `v0.3.1`
+- **Goal**: Close the G-014 lexicon-firewall drift risk (shared synthetic-string helper) and the A-304 hub↔bond const drift risk (cross-package equality test). Both are refactor+test; no behavioral change.
+
+### Wave 1 — Shared helper + cross-const test (parallel; no internal deps)
+
+| Task ID | REQ | Persona | Files | Deliverable | Must-have verification | Blocked-by |
+|---|---|---|---|---|---|---|
+| P1-01-01 | REQ-029 | backend-engineer | `lexicon/lexicon.go` | Add `SyntheticBannedStrings() []string` returning the 10 synthetic strings currently duplicated in both meta-tests. Each string embeds exactly one banned term (from `BannedTerms()`) in a plausible sentence context. Source uses `BannedTerms()` so the lexicon package's own source stays lexicon-clean (fragment-assembled). Add a doc comment cross-referencing G-014 and both consuming meta-tests. | `go build ./lexicon/...` succeeds; `SyntheticBannedStrings()` returns exactly `len(BannedTerms())` strings; each returned string triggers `FindBannedTerm` (self-verifiable in a new test); lexicon package source stays lexicon-clean (the existing `lexicon_meta_test.go` x/ scan does not scan `lexicon/` itself, but the helper must not introduce a banned-term literal). | — |
+| P1-01-02 | REQ-029 | backend-engineer | `lexicon_meta_test.go`, `lexicon_meta_docs/lexicon_meta_docs_test.go` | Refactor `TestLexiconMetaSelfTestTable` and `TestLexiconMetaDocsSelfTestTable` to consume `lexicon.SyntheticBannedStrings()` instead of building their own `synthetic` slice. Remove the duplicated 10-string table from both. Keep the per-string `FindBannedTerm` assertion loop (detection coverage unchanged). Keep the `len(terms) == 10` assertion from `BannedTerms()`. Add a `len(synthetic) == len(terms)` assertion derived from the helper. | `go test ./lexicon_meta... ./lexicon_meta_docs/...` passes; both tests still fail if detection breaks; the duplicated table is gone (grep for the old literal sentence fragments returns zero matches in meta-test files); coverage on both meta-tests does not decrease. | P1-01-01 |

Tests: (1) `TestLendingCouponCapMatchesBondCap` asserts `hub.LendingCouponCapBps == bond.CouponCapBps`; (2) `TestLendingCouponFloorMatchesBondFloor` asserts `hub.LendingCouponFloorBps == bond.CouponFloorBps`; (3) `TestConstsAreMissionLocked800And0` asserts both caps == 800 and both floors == 0 (regression guard for the mission-locked values). Doc comment cross-references A-304 and the G-003 test-exemption. | `go test ./x/hub/types/...` passes; all three tests green at current values (800/0); test fails closed if either const drifts; NO production file in `x/hub/types/` imports `x/bond/types` (G-003 production firewall intact — verified by a grep of non-test `.go` files). | — |

+| P2-01-01 | REQ-031 | lead-developer | `.ciagent/oy/ARCHITECTURE.md` | Add a "Council Voice/Council Interface — Lifecycle Type Divergence Decisions (v0.4)" subsection under the v0.4 Architecture section. Document: (a) P1-1 `Proposal`/`ProposalStatus`/`VoteOption` absent — deferred to v0.5+ governance runtime (feat:-class, rejected by D-001); (b) P1-2 `SignalKind` 4 sources (Stash/Standing/Vouch/Capital) vs spec `VoiceSource` 5 sources — the AUDIT rationale (Freeholder is eligibility, Guild is council tier, Capital is committed-capital per vision §9.1) and the decision to KEEP the 4-source shape; (c) the Bearers `ValidateGenesis` no-op is correct per spec (P2, no action). Cross-reference AUDIT §193 P1-1/P1-2/P2. | The ARCHITECTURE.md section exists and names both P1 divergences + the P2 no-action; a reader can find why Proposal/VoteOption are absent and why SignalKind is 4-not-5 without re-reading AUDIT. | — |
+| P2-02-01 | REQ-031 | backend-engineer | `x/council/types/types_test.go` | Add `TestSignalKindShapeIntentional` — an intent-assertion test that documents and guards the 4-source `SignalKind` shape. Asserts: `SignalKindCount == 4`; `AllSignalKinds()` returns exactly [Stash, Standing, Vouch, Capital]; a doc-comment block above the test explaining the AUDIT §193 P1-2 rationale (why Freeholder and Guild are NOT signal kinds, why Capital IS) so a future agent does not "fix" the divergence by silently changing the locked const. This is a regression GUARD, not a shape change — the existing `TestSignalKindCountLockedConst` already locks the count; this test adds the INTENT documentation. | `go test ./x/council/types/...` passes; the new test fails if `SignalKindCount` changes from 4; the test's doc comment explains the rationale. | — |

+## Coverage Targets (D-033) — v0.4
+
+v0.4 does not lower the v0.3 coverage floor (93.3% on the lowest package). The modified packages must not decrease:
+- `lexicon` (if coverage applies — it's a helper package): maintain or improve.
+- `lexicon_meta` / `lexicon_meta_docs`: maintain 100% (test-only packages).
+- `x/hub/types`: the new `cross_const_test.go` ADDS coverage; do not decrease.
+- `x/council/types`: the new intent test ADDS coverage; do not decrease.
+
+No new packages are created, so no new 80% floor is set.

+## MVP/UX Check (REQ-MVP-UX-001) — v0.4 NFR Milestone
+
+> Auto-generated at full autonomy per run.md §MVP/UX CHECK. The three required
+> sections below name at least one user-facing surface, a happy path written
+> BEFORE execute, and explicit UX acceptance criteria. v0.4 is an NFR milestone,
+> so "user-facing surface" is developer-facing (the lexicon firewall, the
+> cross-const test, the CI workflow) and the docs site build (end-user-facing
+> via the published docs artifact).
+
+### User-Facing Surface
+
+1. **Lexicon firewall (developer-facing)**: `go test ./lexicon_meta... ./lexicon_meta_docs/...` — the green test output is the surface a developer sees on every `go test ./...` run. After REQ-029, both meta-tests consume `lexicon.SyntheticBannedStrings()`; a future banned-term addition updates both firewalls from one place.
+2. **Cross-const drift test (developer-facing)**: `go test ./x/hub/types/...` — `TestConstsAreMissionLocked800And0` is the surface a developer sees if the hub↔bond mission-locked consts ever drift.
+3. **Docs build CI (end-user-facing via artifact)**: `.gitea/workflows/docs-build.yml` produces a `site/` artifact on every push. A maintainer downloads the artifact to preview the docs site without running `mkdocs build` locally.
+4. **ARCHITECTURE.md divergence section (developer-facing)**: a contributor reading `.ciagent/oy/ARCHITECTURE.md` finds the "Council Voice/Council Interface — Lifecycle Type Divergence Decisions (v0.4)" subsection explaining why `SignalKind` is 4-not-5 and why `Proposal`/`VoteOption` are absent.
+
+### Happy Path
+
+**Scenario: a contributor adds an 11th banned term to the lexicon firewall.**
+
+1. The contributor edits `lexicon/lexicon.go` to add a new fragment pair to `fragments` (e.g., a new banned term).
+2. `lexicon.BannedTerms()` now returns 11 strings.
+3. `lexicon.SyntheticBannedStrings()` (REQ-029) is the single source — the contributor does NOT need to update two meta-test tables (the v0.3 drift risk).
+4. `go test ./lexicon_meta... ./lexicon_meta_docs/...` — both meta-tests consume the helper; the `len(terms) == 10` assertion in BOTH meta-tests now fails (expecting 11), alerting the contributor to update the count assertion in both files.
+5. The contributor updates the `len(terms) == 11` assertion in both meta-tests (the G-014 minimum — both already derive count from `BannedTerms()`).
+6. Both meta-tests pass; the new banned term is now enforced in BOTH the `x/**/*.go` firewall AND the `docs/**/*.md` firewall from one source change.
+7. The contributor pushes; `.gitea/workflows/docs-build.yml` (REQ-032) runs `go-test` (green) → `docs-build` (green, G-016 gating) → `site/` artifact uploaded.
+
+**Scenario: a contributor accidentally changes `x/bond.CouponCapBps` from 800 to 900 without updating `x/hub.LendingCouponCapBps`.**
+
+1. `go test ./x/hub/types/...` — `TestLendingCouponCapMatchesBondCap` (REQ-030) fails: `hub.LendingCouponCapBps (800) != bond.CouponCapBps (900)`.
+2. `TestConstsAreMissionLocked800And0` (G-015) ALSO fails: `bond.CouponCapBps (900) != 800`.
+3. The contributor sees two failures pointing at the same root cause; the mission-locked 8% cap is defended by the cross-const test. The v0.3 A-304 drift risk is closed.
+
+### UX Acceptance Criteria
+
+The v0.4 deliverable MUST meet these explicit criteria (verified in P4 audit):
+
+1. **REQ-029**: `lexicon.SyntheticBannedStrings()` exists; both `lexicon_meta_test.go` and `lexicon_meta_docs/lexicon_meta_docs_test.go` consume it; the duplicated 10-string table is gone (grep for the old literal sentence fragments returns zero matches in meta-test files).
+2. **REQ-030**: `x/hub/types/cross_const_test.go` exists; `TestLendingCouponCapMatchesBondCap`, `TestLendingCouponFloorMatchesBondFloor`, and `TestConstsAreMissionLocked800And0` all pass (G-015); no production `.go` file in `x/hub/types/` imports `x/bond/types` (G-003 production firewall intact).
+3. **REQ-031**: ARCHITECTURE.md has the Council lifecycle divergence subsection; `TestSignalKindShapeIntentional` in `x/council/types/types_test.go` passes and documents the 4-signal rationale; `SignalKindCount` unchanged (still 4); no production `.go` files modified in P2.
+4. **REQ-032**: `.gitea/workflows/docs-build.yml` parses; runs `go test ./...` then `mkdocs build` (G-016: `docs-build` needs `go-test`); `go.mod` unchanged.
+5. **NFR purity gate**: zero `feat:` commits in the v0.4 milestone range (P4 audit enforces).
+6. **No regression**: `go test ./...` green; v0.3 coverage floor (93.3%) not reduced on any modified package.
+

+# Plans: OpenYield (oy) — v0.5 (Bearers Runtime)
+
+> This section APPENDS the v0.5 milestone plan to the v0.1/v0.2/v0.3/v0.4

+
+## Milestone Summary
+
+- **Milestone**: v0.5 — Bearers Runtime
+- **Type**: Feature (all execution phases P1..P7 are `feat`; P8 is `final`)
+- **Tag base**: `v0.4.x` patch line (P0 → `v0.4.0`; execution P1..P7 → `v0.4.1..v0.4.7`; final P8 → `v0.4.8` IS the v0.5 milestone release)
+- **Phases**: 8 — P1..P7 (execution) + P8 (final review/audit/ship). Phase 0 (this PLAN) is in progress.
+- **Depth**: runtime promotion (keeper MsgServer handlers + simtest-grade end-to-end flows, NOT mainnet — D-054/D-020 continues). The v0.3 skeleton `types/` contracts are NOT amended; runtime adds behavior on top.
+- **Coverage target**: ≥80% on each runtime package (keeper + simtest; D-033 carries forward).
+- **Modules promoted to runtime**: 8 (`x/exit`, `x/bridge`, `x/bearers`, `x/partner`, `x/hub`, `x/services`, `x/bond`, `x/council`). New enum types: 3 in `x/council` (`ProposalKind`, `ProposalStatus`, `VoteOption`) + `Proposal` struct (AUDIT §193 P1-1). New interface: `CustodyKeyring` (D-058). New dep: cosmos-sdk v0.50.x + ibc-go v8.x (D-055, GRILL-ratified G-006 controlled exception).
+- **Phase ordering** (D-056): P1 exit+bridge → P2 bearers → P3 anchors → P4 hub → P5 services → P6 bond → P7 council → P8 final. Outer→inner dependency chain (fewest internal deps first; each phase independently shippable).
+- **Personas** (from PERSONAS.md): backend-engineer (all P1..P7 handler + simtest work; spans all runtime phases), lead-developer (P0 + P8 + coordination + GRILL-ratification follow-through), security-engineer (CustodyKeyring D-058, CLOB clamp D-057, IBC replay, Mission-Lock const firewall — REACTIVATED), cosmos-engineer (MsgServer/expected-keepers/simtest scaffolding, cosmos-sdk dep D-055 — REACTIVATED), mesh-engineer (P2 bearer session lifecycle — REACTIVATED, P2 phase-specific), data-engineer (P4 hub custody state, in-memory test store — REACTIVATED, P4 phase-specific). ci-security-auditor activated in P8.

+
+**G-003 firewall (survives runtime promotion):** keepers use `expected_keepers.go` interface shims (ibc-go convention) for cross-module keeper calls — NO production struct imports across `x/<module>/types`. The P3→P4 hub dependency is broken this way (hub keeper INTERFACE exists in `x/partner/types/expected_keepers.go` in P3 territory; the hub keeper IMPL is wired in P4). Test-only cross-package imports remain exempt (the G-003 test exemption, used by REQ-030 in v0.4; simtest may import multiple `x/*/keeper` packages to wire shims).
+
+**G-006 controlled exception (D-055, GRILL-ratified):** `go.mod` gains `cosmos-sdk v0.50.x` + `ibc-go v8.x` (A-504, planner confirms the exact pin). Scoped to runtime phases P1..P7; P0 + P8 stay dep-neutral where possible. `types/` packages gain `sdk.Msg` imports for `Msg*` types (isolated in `types/msg_*.go`); invariant/lexicon tests stay stdlib-only and green.
+
+### Planner-Escalation Decisions (provisional, GRILL ratifies)
+
+The 4 planner-escalation items from RESEARCH §4 (low-confidence assumptions) are resolved here as provisional planner decisions D-062..D-065 (continuing the decision ID sequence from D-061). They are PROVISIONAL until the GRILL stage ratifies them.
+
+| ID | Decision | Rationale | Confidence | Alternatives |
+|----|----------|-----------|------------|--------------|
+| D-062 | **cosmos-sdk / ibc-go version pin = cosmos-sdk v0.50.x + ibc-go v8.x** (resolves A-504). v0.50.x is the LTS line (go 1.22-compatible); ibc-go v8.x is the stable pairing for cosmos-sdk v0.50. ibc-go v10 (IBC v2 / Eureka) is the documented target pattern but a newer pin — defer to a later upgrade. Mark GRILL-confirmed. | v0.50.x + ibc-go v8.x is the stable, widely-deployed pairing (Osmosis, dYdX-v4 lineage); v10 IBC-v2 is attractive but newer and risks churn in a runtime-promotion milestone. The IBC v2 patterns are documented in RESEARCH but the v0.5 impl uses the v8 stable interfaces. | 0.78 | [cosmos-sdk v0.50.x + ibc-go v10 (IBC v2/Eureka, newer); cosmos-sdk v0.47.x + ibc-go v7.x (older LTS)] |
+| D-063 | **Bond CLOB match above 800 bps = REJECT (fails closed)**, NOT clamp-with-refund (resolves A-562). D-057 says "hard clamp on each match"; the runtime interpretation is reject-above-cap. A match whose implied coupon exceeds `CouponCapBps=800` bps is REJECTED — the trade fails closed, the resting order stays, the incoming order rests or is cancelled. The mission-lock is a hard invariant (a usury violation), not a soft cap to be clamped with a refund path. Matches within [0, 800] bps use the v0.3 `Clamp` helper (clamp-within-band is safe — no refund needed since the value is already in-band). | Reject is simpler (no refund path) and is the mission-lock-true choice: a trade above the cap is a usury violation, not a clampable excess. The Fee Covenant `Clamp` shape (clamp, not reject) applies to ISSUANCE (a coupon field set by the issuer), but MATCHING is a market-determined price — a match above the cap is a violation, not an input to clamp. REJECT fails closed (the safer choice for the highest-severity locked const). | 0.70 | [clamp-with-refund (the match clears at 800, excess refunded to seller) — adds a refund path, softens the mission-lock] |
+| D-064 | **`MissionLockAmendment-Rejected` ProposalKind rejected at `ValidateBasic`** (resolves A-572). The `MsgSubmitProposal` `ValidateBasic` REJECTS a proposal of kind `MissionLockAmendment-Rejected` — the message never reaches the handler. The const `MissionLockAmendable = false` (v0.2 locked) is the firewall; the `ValidateBasic` is the gate. The proposal is unproposable, not propose-then-fail. The v0.2 `TestMissionLockAmendableFalse` regression test stays green. | The const is the firewall; the `ValidateBasic` gate is the dual firewall. Rejecting at `ValidateBasic` is the cleanest: the message never enters the keeper, no state record is created, no event is emitted. Propose-then-fail (record Pending → auto-transition Failed with event) would document the rejection on-chain but creates a state record for an unproposable proposal — unnecessary state growth. The Mission-Lock-non-amendable design intent is "unproposable", not "propose-then-fail". | 0.80 | [propose-then-fail (record Pending, auto-transition Failed with "Mission Lock non-amendable" event) — documents the rejection on-chain but creates dead state] |
+| D-065 | **Watcher Veto quorum default = 6** (resolves A-574), matching REQ-004's 6-of-9 Watcher quorum. A single Veto does NOT block (anti-greed, vision §19); the proposal transitions to Failed only if `NoWithVeto >= WatcherVetoQuorum` (a `Params` field, NOT a locked const — the v0.2 Params struct was empty, v0.5 P7 adds `WatcherVetoQuorum` defaulting to 6). The quorum is a param (governance-tunable in a future milestone) rather than a locked const, to allow adjustment without a locked-const amendment. | REQ-004 fixes the Watcher quorum at 6-of-9; the Veto quorum mirrors it (a Watcher-coordinated veto requires the same quorum as a Watcher attestation). A single Veto blocking would violate the anti-greed principle (vision §19 — no single-actor veto gate). Defaulting to 6 (not locking as a const) lets a future governance vote adjust the quorum without a Mission-Lock-class amendment (Veto quorum is NOT a Mission-Lock const; the distinction is documented in v0.4 ARCHITECTURE.md). | 0.75 | [lock WatcherVetoQuorum=6 as a const (over-rigid; prevents future tuning); default 9 (requires all Watchers, too high a bar for a veto)] |
+
+> These 4 decisions are surfaced through the normal decision flow (planner →
+> GRILL ratification). They are NOT auto-decided (the autonomy threshold for
+> locked-const-shape and dep-pinning decisions is at the GRILL boundary per
+> PERSONAS.md lead-developer constraints). The GRILL stage may ratify, amend,
+> or reject them; if rejected, the planner re-resolves before the affected

+- **IBC ack/timeout handling (CVE-class pitfall, A-513)** → simtest MUST cover both replay (second ack rejected) and timeout-refund (exactly-once refund). security-engineer reviews the simtest.
+- **Solana guardian sig set rotation** → handler reads CURRENT set from state, not hardcoded; simtest uses a frozen stub set; rotation test deferred (D-054).
+- **Denom trace drift** → parser pinned to ICS-20 v1 `transfer/channel-N/<denom>` shape (v0.2 satellite); simtest asserts the trace parse.
+- **cosmos-sdk version pin churn (D-062)** → v0.50.x + ibc-go v8.x is the stable choice; GRILL ratifies before P1 ships.

+- [ ] `ProposalKindCount=4` (incl. `MissionLockAmendment-Rejected`), `ProposalStatusCount=5`, `VoteOptionCount=4` locked-consts added.
+- [ ] `MissionLockAmendment-Rejected` ProposalKind rejected at `ValidateBasic` (D-064/A-572 — never reaches handler).
+- [ ] Watcher Veto quorum default 6 (D-065/A-574); single Veto does NOT block (anti-greed).
+- [ ] `MissionLockAmendable=false` UNCHANGED (v0.2 `TestMissionLockAmendableFalse` green).
+- [ ] `SignalKindCount=4` UNCHANGED (v0.4 `TestSignalKindShapeIntentional` green); expansion to 5 deferred to v0.6+.
+- [ ] No proposal auto-execution (handler records tally only; execution is v0.6+).
+- [ ] `go build ./...` and `go test ./...` green (no regression).
+- [ ] ≥80% coverage on `x/council/keeper` + `x/council/types`.

+- [ ] Git tag `v0.4.7`.
+
+### P7 Risks & Mitigations
+- **Mission Lock const firewall integrity (D-064/A-572)** → `ValidateBasic` rejects `MissionLockAmendment-Rejected` kind; the const is the firewall, `ValidateBasic` is the gate; v0.2 regression test green.
+- **Veto semantics (D-065/A-574)** → single Veto does NOT block (anti-greed); quorum-based (default 6); simtest covers single-Veto-no-block + quorum-Veto-fails.
+- **SignalKind 4-not-5 (A-573)** → UNCHANGED; v0.4 regression-guard test green; expansion deferred to v0.6+ governance vote (not a Mission-Lock const; a distinct locked const).

+- [ ] Milestone branch merged to `main`.
+- [ ] All 8 phase branches deleted (local + remote).
+
+### P8 Risks & Mitigations
+- **Runtime promotion breaks v0.3 type contracts** → the v0.3 `types/` packages are NOT amended (runtime adds behavior on top); the feature purity gate verifies no struct field removal/enum rename.
+- **G-006 dep exception churn** → D-055/D-062 GRILL-ratified; the pin (cosmos-sdk v0.50.x + ibc-go v8.x) is the stable choice; the audit verifies the dep is scoped to runtime phases.
+- **Milestone versioning confusion (v0.5 milestone = v0.4.8 tag)** → lead-developer enforces D-008: final phase patch IS the milestone release; no separate minor tag. ROADMAP tag-line note (P8-03-01) prevents `v0.4.8`/`v0.5.0` confusion.

Per-module lexicon assertions added to each new `keeper/` package. Highest-risk surfaces: `x/hub` custody Msg names (AVOID "deposit" — use `MsgCustodyReceiveAsset`/`MsgCustodyReleaseAsset` A-542); `x/bond` (no "interest"/"yield" — use "coupon"/"growth"); `x/council` ("veto"/"VoteOption" safe).

+## Cross-Phase Blockers (hard) — v0.5
+
+- **P1-01-01 (cosmos-sdk + ibc-go dep, D-062 GRILL)** → blocks P1-02-01 and all subsequent runtime work (the dep must land before any `Msg*`/`sdk.Msg`/`MsgServer` compiles). GRILL ratifies D-062 before P1 ships.
+- **P1-03-01 (x/bridge keeper)** → blocks P1-05-01 (x/exit keeper — `BridgeKeeper` shim wired to the real `x/bridge` keeper in simtest).
+- **P1-99-01 (P1 ship)** → blocks P2-01-01 (bearers routes through exit; branch hygiene + G-003 import-invariant test scanning the new files).
+- **P2-99-01 (P2 ship)** → blocks P3-01-01 (anchors ride bearers).
+- **P3-01-01 (x/partner expected-keepers incl. HubKeeper shim)** → the P3→P4 hub dep is broken here (interface in P3; impl wired in P4). P4-04-01 wires the real `x/hub` keeper to the `PartnerKeeper` shim in `x/hub`'s expected-keepers.
+- **P3-99-01 (P3 ship)** → blocks P4-01-01 (hub custody backs anchors; the `PartnerKeeper` shim in `x/hub/types/expected_keepers.go` is wired to the real `x/partner` keeper).
+- **P4-99-01 (P4 ship)** → blocks P5-01-01 (services sit on hub) and P6-01-01 (bond uses hub lending primitive — the cross-const test guards the shared 800/0 consts).
+- **P5-99-01 (P5 ship)** → blocks P6-99-01? No — P6 depends on P4 (hub lending), not P5. P5 and P6 are both blocked by P4; they could run in parallel if parallelization were enabled (config `parallelization.enabled: false` — serial).
+- **P6-99-01 (P6 ship)** → blocks P7-01-01 (council is cross-cutting, lands last).
+- **P7-99-01 (P7 ship)** → blocks P8-01-01 (P8 audit).
+- **D-062 (cosmos-sdk pin)** → must be GRILL-ratified before P1 ships.
+- **D-063 (bond match reject)** → must be resolved before P6 ships (resolved here, provisional until GRILL).
+- **D-064 (MissionLockAmendment ValidateBasic reject)** → must be resolved before P7 ships (resolved here, provisional until GRILL).

+## v0.5 Decisions Applied (D-054..D-065 + A-501..A-574)
+
+The v0.5 Phase 0 clarify/research stages produced 8 clarification decisions (D-054..D-061) and 4 planner-escalation decisions (D-062..D-065, provisional until GRILL), applied to this plan:
+
+| ID | Decision | Applied to |
+|---|---|---|
+| D-054 | Runtime = simtest-grade handlers, NOT mainnet | All P1..P7 simtest tasks; P8 audit |
+| D-055 | cosmos-sdk dep GRILL-approved (G-006 controlled exception) | P1-01-01 (go.mod); all runtime phases |
+| D-056 | Phase ordering P1 exit → P2 bearers → P3 anchors → P4 hub → P5 services → P6 bond → P7 council → P8 final | Cross-Phase Dependency Map; all phase goals |
+| D-057 | Bond CLOB matching (not AMM); 8%/0% per-match clamp | P6-02-01 (CLOB), P6-03-01 (simtest) |
+| D-058 | Hub custody = CustodyKeyring interface + memKeyring test impl (no real MPC) | P4-01-01, P4-02-01 |
+| D-059 | IBC packet scope = 5 locked L2 chains; Solana via wormhole-adapter | P1-03-01 (bridge IBC handlers) |
+| D-060 | Council governance: add Proposal/VoteOption enums (AUDIT §193 P1-1); MissionLockAmendment-Rejected kind; SignalKind stays 4 | P7-01-01, P7-02-01, P7-03-01 |
+| D-061 | No IDEATE in v0.5 (no --ideate flag) | (no IDEATE stage run) |
+| D-062 (provisional) | cosmos-sdk v0.50.x + ibc-go v8.x version pin (resolves A-504) | P1-01-01 (go.mod); GRILL ratifies |
+| D-063 (provisional) | Bond match above 800 bps = REJECT (fails closed) (resolves A-562) | P6-02-01 (CLOB match), P6-03-01 (simtest); GRILL ratifies before P6 |
+| D-064 (provisional) | MissionLockAmendment-Rejected rejected at ValidateBasic (resolves A-572) | P7-01-01 (MsgSubmitProposal.ValidateBasic), P7-03-01 (simtest); GRILL ratifies before P7 |
+| D-065 (provisional) | Watcher Veto quorum default 6 (resolves A-574) | P7-01-01 (Params.WatcherVetoQuorum), P7-02-01 (tally), P7-03-01 (simtest); GRILL ratifies before P7 |
+
+### Research assumptions applied (A-501..A-574, selected)
+
+| ID | Assumption | Applied to |
+|---|---|---|
+| A-501 | Every v0.5 target module gains a `keeper/` subdir + `msg_server.go`; `types/` stays the locked-contract layer | All P1..P7 keeper tasks |
+| A-505 | Keeper-to-keeper cross-module calls use `expected_keepers.go` interface shims; G-003 by-ID-string rule preserved | All `types/expected_keepers.go` tasks; G-003 import-invariant |
+| A-513 | IBC ack/timeout replay protection mirrors ibc-go (delete-on-ack, refund-on-timeout); simtest covers both | P1-03-01, P1-06-01 (bridge simtest) |
+| A-521 | OY-QR one-shot: MsgConsumeOYQR flips `consumed` before the transfer effect; replay rejected idempotently | P2-02-01, P2-03-01 (bearers simtest) |
+| A-522 | BearerTransport gains a store-backed impl (keeper as transport in simtest); no hardware/RF dep | P2-02-01 |
+| A-531 | Anchor credential lifecycle = Pending → Onboarded → Suspended → Revoked | P3-02-01 |
+| A-532 | P3→P4 hub dependency broken by `expected_keepers.go` shim; hub runtime impl wired in P4 | P3-01-01 (HubKeeper interface), P4-04-01 (wired) |
+| A-533 | Revocation authz delegates to `x/watcher` expected-keeper shim (6-of-9 quorum); no struct import | P3-01-01, P3-02-01 |
+| A-541 | CustodyKeyring interface (Sign/Derive/Status) + memKeyring in-memory test impl | P4-01-01, P4-02-01 |
+| A-542 | Custody message names AVOID "deposit"; use `MsgCustodyReceiveAsset`/`MsgCustodyReleaseAsset` | P4-03-01 |
+| A-543 | Lending handler clamps coupon to [0, 800] bps at runtime; clamp event emitted | P4-04-01, P4-05-01 |
+| A-544 | Compliance-before-custody ordering enforced (withdrawal checks compliance before debit) | P4-04-01, P4-05-01 |
+| A-551 | Per-kind service message handlers (one `Msg*` per ServiceKind), NOT a generic dispatch | P5-01-01 |
+| A-552 | `window-id` grant checked on EVERY service operation (revoked Window invalidates ops) | P5-02-01, P5-03-01 |
+| A-561 | CLOB matching with price-time priority (FCFS at same price, REQ-007); per-tx matching in simtest | P6-02-01 |

+## MVP/UX Check (REQ-MVP-UX-001) — v0.5 Feature Milestone
+
+> Auto-generated at full autonomy per run.md §MVP/UX CHECK. v0.5 is a
+> **feature** milestone (runtime promotion); "user-facing surface" is
+> developer-facing (the MsgServer handlers, the simtest output, the
+> `CustodyKeyring` interface, the CLOB matching engine) and the protocol
+> semantics (Anchor credential lifecycle, council governance with the
+> Mission-Lock const firewall). No end-user UI changes (the docs site is
+> complete from v0.3; no new docs pages in v0.5).
+
+### User-Facing Surface
+
+1. **MsgServer handlers (developer-facing)**: each `x/<module>/keeper/msg_server.go` exposes one `*Response, error` method per `Msg*`. A developer invoking `go test ./x/.../keeper/...` sees the simtest exercise each handler against an in-memory `sdk.Context`. The green test output is the surface.
+2. **CustodyKeyring interface (developer-facing)**: `x/hub/types/keyring.go` defines the `CustodyKeyring` interface (`Sign`/`Derive`/`Status`); a custody vendor integration team implements it. The interface is the contract surface.
+3. **CLOB matching engine (developer-facing)**: `x/bond/keeper/clob.go` implements the price-time-priority CLOB; a developer invoking `MsgMatchSecondaryOrder` sees the resting book matched and the per-match coupon clamped (REJECT above 800 — D-063). The match event is the surface.
+4. **Council governance (protocol-facing)**: `x/council` `MsgSubmitProposal` / `MsgVote` / `MsgTallyProposal` with the `MissionLockAmendment-Rejected` kind rejected at `ValidateBasic` (D-064) — a developer attempting to submit a Mission-Lock-amendment proposal sees a `ValidateBasic` error. The Watcher Veto quorum (default 6, D-065) is the anti-greed gate.
+
+### Happy Path
+
+**Scenario: a developer exercises the OY-QR one-shot bearer transfer end-to-end.**
+
+1. The developer writes a simtest in `x/bearers/keeper/msg_server_simtest_test.go` (or runs the existing one).
+2. `MsgIssueOYQR` creates an `OYQRCode` with `consumed=false`, `expires-at` in the future, a payload, an issuer-reach-id.
+3. `MsgConsumeOYQR` is invoked: the handler loads the QR, asserts `!consumed`, asserts `expires-at > now`, FLIPS `consumed=true` (state write FIRST — A-521), emits the transfer effect via the `BreadKeeper` shim, emits an event, returns.
+4. A REPLAY (second `MsgConsumeOYQR` on the same qr-id) loads the QR, finds `consumed==true`, returns an error (idempotent reject — NOT double-effect).
+5. The simtest asserts: the transfer effect happened exactly once; the replay returned an error; the event set contains NO geolocation fields (surveillance-resistant negative test — A-522).
+6. The simtest is green; coverage on `x/bearers/keeper` ≥80%.
+
+**Scenario: a developer exercises the CLOB bond matching with the per-match clamp.**
+
+1. A resting Sell order is placed at a price implying a 750 bps coupon (within [0, 800] band).
+2. A Buy order arrives matching the Sell; the match clears at 750 bps (within band — `Clamp` is a no-op); the match event asserts the coupon is 750.
+3. A second resting Sell order is placed at a price implying a 900 bps coupon (above the 800 cap).
+4. A Buy order arrives matching the second Sell; the match's implied coupon (900) EXCEEDS `CouponCapBps=800`; the match is REJECTED (fails closed — D-063/A-562); the resting Sell stays; the Buy rests or is cancelled.
+5. The simtest asserts: the in-band match cleared; the above-cap match was rejected; the 8%/0% consts are unchanged (D-028 regression); the REQ-030 cross-const test (hub ↔ bond) is green.
+6. The simtest is green; coverage on `x/bond/keeper` ≥80%.
+
+**Scenario: a developer attempts to submit a Mission-Lock-amendment proposal.**
+
+1. `MsgSubmitProposal` is constructed with `kind = MissionLockAmendment-Rejected`.
+2. `ValidateBasic` runs (stateless gate): the kind is `MissionLockAmendment-Rejected`; `ValidateBasic` REJECTS the message with a Mission-Lock error (D-064/A-572 — the message never reaches the handler).
+3. The handler is never invoked; no Proposal state record is created; no event is emitted.
+4. The simtest asserts: `ValidateBasic` returned a Mission-Lock error; the keeper's Proposal store is empty; the v0.2 `TestMissionLockAmendableFalse` regression test is green (`MissionLockAmendable==false` unchanged).
+5. The simtest is green; coverage on `x/council/keeper` + `x/council/types` ≥80%.
+
+### UX Acceptance Criteria
+
+The v0.5 deliverable MUST meet these explicit criteria (verified in P8 audit):
+
+1. **REQ-033**: `x/exit` + `x/bridge` each have `keeper/msg_server.go` + `types/msg_*.go` + `types/expected_keepers.go` + `module.go`; `go test ./x/exit/... ./x/bridge/...` passes; simtest covers ExitStatus lifecycle + IBC replay/timeout (A-513); coverage ≥80% on both keeper packages; G-003 intact (no `x/bridge/types` struct import in `x/exit` production code).
+2. **REQ-034**: `x/bearers` has `keeper/msg_server.go` + `keeper/transport.go` + `types/msg_bearer*.go` + `types/session.go`; OY-QR one-shot (consumed-before-transfer A-521); surveillance-resistant negative test; `BearerTypeCount=6` unchanged.
+3. **REQ-035**: `x/partner` has `keeper/msg_server.go` + `types/msg_anchor*.go` + `types/expected_keepers.go` (WatcherKeeper + HubKeeper shims); Anchor credential lifecycle (Pending→Onboarded→Suspended→Revoked); P3→P4 hub dep broken by shim; `PartnerTierCount=4` unchanged.
+4. **REQ-036**: `x/hub` has `types/keyring.go` (CustodyKeyring interface D-058) + `keeper/keyring_mem.go` (memKeyring) + `keeper/custody_state.go` + `keeper/msg_server.go`; custody Msg names AVOID "deposit" (A-542); compliance-before-custody (A-544); lending coupon clamp [0, 800] at runtime (A-543); `HubServiceCount=3` + `LendingCouponCapBps=800`/`LendingCouponFloorBps=0` unchanged; REQ-030 cross-const test green.
+5. **REQ-037**: `x/services` has `keeper/msg_server.go` + `types/msg_*.go` (per-kind typed dispatch A-551); window-grant-on-every-op (A-552); `ServiceKindCount=4` unchanged.
+6. **REQ-038**: `x/bond` has `keeper/msg_server.go` + `keeper/clob.go`; CLOB price-time priority (REQ-007); per-match clamp REJECT above 800 (D-063/A-562); no AMM (D-057); `CouponCapBps=800`/`CouponFloorBps=0` unchanged (D-028); REQ-030 cross-const test green; `OrderSideCount=2`/`OrderStatusCount=3` unchanged.
+7. **REQ-039**: `x/council` has `keeper/msg_server.go` + `types/msg_*.go`; `Proposal`/`ProposalKind`(4)/`ProposalStatus`(5)/`VoteOption`(4) enums added (D-060); `MissionLockAmendment-Rejected` rejected at `ValidateBasic` (D-064/A-572); Watcher Veto quorum default 6 (D-065/A-574); single-Veto-no-block (anti-greed); `MissionLockAmendable=false` unchanged (v0.2 regression green); `SignalKindCount=4` unchanged (v0.4 regression green); `CouncilKindCount=3` unchanged; no proposal auto-execution.
+8. **Feature purity gate (P8)**: no breaking schema changes (v0.3 `types/` contracts NOT amended); locked-const firewall intact (all v0.1..v0.4 consts unchanged; new P7 enums per D-060); G-003 production firewall intact (`expected_keepers.go` are interfaces); G-006 controlled exception GRILL-ratified (D-055/D-062).
+9. **No regression**: `go test ./...` green; v0.4 coverage floor (93.3% on `x/hub/types`, 96.4% on `x/council/types`) not reduced on the `types/` packages; v0.1..v0.4 baseline tests green.
+10. **D-055/D-062 dep**: `go.mod` has cosmos-sdk v0.50.x + ibc-go v8.x (GRILL-ratified); `types/` packages gain `sdk.Msg` imports for `Msg*` (isolated in `types/msg_*.go`); invariant/lexicon tests stay stdlib-only and green.

 ## Milestone
-v0.3 — Bearers & Documentation (active milestone; feature type; tags run on the v0.2.x patch line)
+v0.5 — Bearers Runtime (in progress; feature type; tags run on the v0.4.x patch line)
+
+### v0.5 Scope (Live-runtime promotions of the v0.3 Bearers skeletons)
+
+v0.5 promotes the v0.3 Bearers skeletons from type+keeper-stub layers to live
+runtime behavior. This is the first milestone to ship executable behavior
+beyond invariant tests — keepers gain message handlers, transactions, and
+end-to-end flows. Sourced from the v0.3/v0.4 deferred items (D-050,
+PROJECT.md v0.4 out-of-scope, ROADMAP Phase 3 "The Bearers" runtime subset).
+
+The skeleton-first pattern (D-020) continues to govern NEW components, but
+v0.3-era modules (`x/exit`, `x/bridge`, `x/bearers`, `x/partner`, `x/hub`,
+`x/services`, `x/bond`) gain runtime implementations this milestone. No live
+chain launch (D-020 continues to apply to network deployment); runtime here
+means keeper message handlers + simtest-grade end-to-end flows, not mainnet.
+
+- **REQ-033** Exit layer runtime — `x/exit` DEX swap routing + bridge message handlers; `x/bridge` L2↔L1 IBC packet handlers. Promotes REQ-010 from skeleton → runtime. Live DEX/IBC channels still deferred.
+- **REQ-034** Bearers transport runtime — OY-SAT + OY-QR bearer transport message handlers in `x/bearers` (extends REQ-019). Hardware integration deferred; runtime = message-handling + session lifecycle in simtest.
+- **REQ-035** Anchors onboarding runtime — `x/partner` Anchor tier credential issuance + revocation handlers (extends REQ-018). Real institutional onboarding deferred; runtime = credential lifecycle in simtest.
+- **REQ-036** Hub API B2B runtime — `x/hub` custody, lending primitive, compliance message handlers. Real B2B suite deferred; runtime = keeper handlers + simtest.
+- **REQ-037** Services runtime — `x/services` Care / SIM / Vault / Mail service lifecycle handlers. Live service integrations deferred; runtime = lifecycle handlers + simtest.
+- **REQ-038** Bond market depth runtime — `x/bond` Growth Bonds + secondary-market matching handlers (extends REQ-021). Live market depth deferred; runtime = matching engine + simtest.
+- **REQ-039** Council governance runtime — `x/council` Proposal/VoteOption enum types (AUDIT §193 P1-1, deferred from v0.4) + Voice lifecycle handlers. Mission Lock const firewall intact (G-003); runtime = governance message handlers + simtest.
+
+### Milestone Type
+Feature (all execution phases are `feat`). Phase 0 → `v0.4.0`; execution phases `v0.4.1..v0.4.N`; final phase patch `v0.4.(N+1)` IS the v0.5 milestone release. No separate minor tag. The final-phase audit enforces the feature purity gate (no breaking schema changes; locked-const firewall intact).
+
+### Out of Scope (v0.5)
+- Live chain launch / mainnet / real IBC channels / real bearer transports (D-020 pattern continues; runtime = simtest-grade message handlers)
+- Real institutional Anchors onboarding (credential lifecycle in simtest only)
+- Yield Token, Travel + 11 service categories (ROADMAP Phase 4 — Maturity)
+- i18n / MkDocs internationalization
+- Cover Pool seniority mechanics (still deferred per PROJECT.md Q7)
+- Breaking schema changes / locked-const amendments (Mission Lock non-amendable)
+- SignalKind 4→5 enum expansion (AUDIT §193 P1-2; defensible per current rationale, deferred to v0.6+ governance vote)

+
+v0.4 is a refinement-only NFR milestone: zero `feat:` phases. It lands the
+durability fixes v0.3 flagged but did not block on, sourced from REVIEW.md,
+AUDIT.md §193, and GRILL.md G-014. Live-runtime promotions of the v0.3 Bearers
+skeletons are out of scope (deferred to v0.5+).
+
+- **REQ-029** Lexicon firewall shared helper (`lexicon.SyntheticBannedStrings()`) — dedupe the synthetic self-test table between `lexicon_meta_test.go` and `lexicon_meta_docs_test.go`. Both meta-tests derive count + strings from the single `lexicon` package source, so a future banned-term addition updates both firewalls from one place. (GRILL G-014)
+- **REQ-030** Cross-package const-equality test — `x/hub.LendingCouponCapBps == x/bond.CouponCapBps` (and Floor). Test-only import (G-003 exempt). Catches silent mission-lock drift between hub LOCAL consts and bond D-028 consts. (REVIEW.md P2 / A-304)
+- **REQ-031** x/* lifecycle type shape-divergence review + alignment fixes — audit non-must-have lifecycle types across modules flagged by AUDIT §193; align where divergent without behavioral change. (AUDIT.md §193)
+- **REQ-032** Docs build CI — Gitea Actions workflow running `go test ./...` (lexicon firewall) + `mkdocs build` on every push; upload `site/` as a CI artifact. Full Gitea Pages publishing deferred if no hosting target configured. (D-046)
+
+### Milestone Type
+NFR (all phases are refactor/test/quality/chore). Phase 0 → `v0.3.0`; execution phases `v0.3.1..v0.3.3`; final phase patch `v0.3.4` IS the milestone release. No separate minor tag. The final-phase audit enforces the NFR purity gate (zero `feat:` commits).

+| ID | Decision | Rationale | Confidence | Alternatives |
+|----|----------|-----------|------------|--------------|
+| D-047 | **v0.4 milestone type = NFR** (all phases refactor/test/quality/chore). Zero `feat:` phases by construction. Tags run on the `v0.3.x` patch line: P0 → `v0.3.0`, P1..P3 → `v0.3.1..v0.3.3`, final phase P4 → `v0.3.4` (milestone release).

Promoting any Bearers skeleton to live runtime would be `feat:` and is deferred to v0.5+. | 0.90 | [feature milestone promoting v0.3 skeletons to live runtime] |
+| D-048 | **REQ-029 lexicon shared helper**: add `lexicon.SyntheticBannedStrings() []string` to the `lexicon` package; both `lexicon_meta_test.go` and `lexicon_meta_docs_test.go` consume it instead of duplicating their own synthetic self-test tables. Both already assert `len(terms) == 10` from `lexicon.BannedTerms()` (G-014 minimum met); the helper closes the drift risk fully. | GRILL G-014 binding fix. Single source of truth for synthetic banned strings; a future banned-term addition updates both firewalls from one place. Refactor+test (NFR-eligible). | 0.88 | [cross-reference comment only (G-014 minimum)] |
+| D-049 | **REQ-030 cross-package const-equality test**: new test file `x/hub/types/cross_const_test.go` (package `types`) that imports `x/bond/types` (test-only, G-003 exempt) and asserts `hub.LendingCouponCapBps == bond.CouponCapBps` and `hub.LendingCouponFloorBps == bond.CouponFloorBps`. Test-only import does not violate G-003 (production-import firewall). | REVIEW.md P2 / A-304. Catches silent mission-lock drift between hub LOCAL consts and bond D-028 consts. Test (NFR-eligible). | 0.85 | [document manual-sync requirement in ARCHITECTURE.md only] |
+| D-050 | **REQ-031 lifecycle type shape-divergence review scope = DOCUMENT only, no code shape changes**. AUDIT §193 P1-1 (council Proposal/VoteOption absent) and P1-2 (SignalKind 4 vs 5 sources) are `feat:`-class additions (new enum types / locked-const shape changes) and are REJECTED by the D-001 refinement-only filter. v0.4 REQ-031 ships an ARCHITECTURE.md section documenting the divergence decisions (P1-2 defensible per AUDIT code rationale; P1-1 deferred to v0.5+ governance runtime) + a test asserting the current `SignalKindCount==4` locked-const shape is intentional (regression guard, not a shape change). | Adding Proposal/VoteOption enums is `feat:`; changing SignalKind 4→5 is a locked-const change. Both are out-of-scope for an NFR milestone. Documentation + a regression-guard test are NFR-eligible. | 0.82 | [add Proposal/VoteOption enums (feat:, deferred to v0.5+)] |
+| D-051 | **REQ-032 docs build CI = Gitea Actions workflow** at `.gitea/workflows/docs-build.yml` running `go test ./...` (lexicon firewall) + `mkdocs build` on every push; upload `site/` as a CI artifact. Full Gitea Pages publishing is deferred (no hosting target configured in v0.4). The workflow file itself is a `chore` (config, not feature). | D-046 forward-reference. `.github/workflows/` does not exist; Gitea Actions uses `.gitea/workflows/`. Build+artifact CI is `chore` (NFR-eligible); full Pages publish needs a hosting target (deferred). | 0.80 | [include full Gitea Pages publish (needs hosting target + secrets)] |
+| D-052 | **Phase ordering** (provisional, planner finalizes): P1 lexicon hardening (REQ-029 + REQ-030 — same `lexicon`/test territory, vertical slice) → P2 lifecycle divergence documentation + regression guard (REQ-031) → P3 docs build CI (REQ-032) → P4 final review + audit + milestone ship.

+
+Auto-decided defaults logged per clarify workflow Step 4 (full autonomy → accept defaults, log decisions). No `--ideate` flag this run; v0.5 scope is pre-seeded from PROJECT.md v0.4 out-of-scope + AUDIT §193 P1-1 + D-050 and ratified at CLARIFY.
+
+| ID | Decision | Rationale | Confidence | Alternatives |
+|----|----------|-----------|------------|--------------|
+| D-054 | **"Runtime" = simtest-grade keeper message handlers + end-to-end flows, NOT mainnet.** v0.5 ships executable keeper behavior (MsgServer handlers, keeper Set/Get/Remove, simtest `simtest`-package flows) for the v0.3 Bearers modules. No live chain launch, no real IBC channels, no real bearer transports, no real institutional onboarding (D-020 pattern continues to govern network deployment). | v0.3 skeletons are types + keeper stubs + invariant tests. The next increment is message handlers + simtest, which is the Cosmos-SDK standard pre-mainnet step. Mainnet deployment is a Year-3+ operational concern (Watchers + Root Basket backing required). | 0.88 | [full mainnet launch in v0.5; types-only with no handlers (stalls progress)] |
+| D-055 | **Cosmos SDK dependency is GRILL-approved for v0.5.** `go.mod` gains `github.com/cosmos/cosmos-sdk` (and transitive deps) as the runtime substrate for keeper MsgServer handlers, `types.Msg`, `sdk.Context`, store, and simtest. This is a controlled exception to G-006 (zero-dep go.mod), escalated to GRILL for binding ratification. The exception is scoped to runtime promotion phases (P1..P7); P0 and the final phase remain dep-neutral where possible. | v0.3 skeletons used stub `keeper.go` files that already import cosmos-sdk (see LSP errors on `x/watcher/keeper/keeper.go` — pre-existing imports). Promoting to runtime makes the dependency load-bearing rather than stub-only. G-006's intent (zero-dep for skeleton durability) is preserved by isolating the dep to runtime phases and keeping types/invariants dep-free. | 0.80 | [stay zero-dep, hand-roll keeper store + message types (duplicates SDK, high risk); defer all runtime to v0.6+ (stalls)] |
+| D-056 | **Phase ordering** (provisional, planner finalizes): P1 Exit+Bridge runtime (REQ-033, Layer 3 — outermost edge, fewest internal deps) → P2 Bearers transport runtime (REQ-034, depends on exit for off-mesh routing) → P3 Anchors runtime (REQ-035, depends on partner + bearers) → P4 Hub API runtime (REQ-036, depends on anchors for custody backing) → P5 Services runtime (REQ-037, depends on hub) → P6 Bond market runtime (REQ-038, depends on hub lending primitive) → P7 Council governance runtime (REQ-039, cross-cutting, lands last) → P8 final review + audit + milestone ship. Each phase independently shippable; P1 lands the outermost edge first (lowest internal coupling). | The dependency chain is outer→inner: exit needs nothing internal; bearers routes through exit; anchors ride bearers; hub custody backs anchors; services sit on hub; bond matching uses hub lending; governance is cross-cutting. Vertical slices, each phase shippable. | 0.82 | [governance-first; bond-first; single mega-phase] |
+| D-057 | **Bond matching engine = central-limit order book (CLOB) with the 8% cap / 0% floor consts (D-028) as hard clamp on each match.** No AMM (constant-product or otherwise) in v0.5; AMM is a Year-4 Maturity concern. The CLOB matches Growth Bond bids/offers at the locked coupon cap; secondary-market trades clear at market price but the bond's *coupon* stays within the mission-locked band. REQ-038 ships the matching handler + simtest; live market depth deferred. | CLOB is the standard secondary-market primitive; AMM is for spot/swaps (Exit layer's DEX, deferred). The mission-lock clamp (D-028) is a per-match invariant, not a market-wide cap. CLOB lets the cap be enforced per-match. | 0.80 | [AMM (wrong fit for coupon-bearing bonds); batch auction (deferred to Maturity)] |
+| D-058 | **Hub custody model = key-share abstraction (MPC-via-interface, not a concrete HSM/MPC vendor).** `x/hub` custody handlers expose a `CustodyKeyring` interface with `Sign`/`Derive` methods; v0.5 ships an in-memory test-only implementation. Real MPC/HSM backing is deferred (operational, Year 3+). This keeps v0.5 dep-neutral w.r.t. custody vendors while landing the handler surface. | Custody key management is operational, not protocol-level. An interface + test impl lets runtime handlers be exercised in simtest without committing to a vendor. GRILL reviews the interface boundary. | 0.78 | [commit to a specific MPC vendor (premature); hand-roll shamir (out of scope)] |
+| D-059 | **IBC packet scope = the 5 L2 chains already in the v0.2 skeleton** (Polygon, Base, Arbitrum, Optimism, Solana per REQ-009/`x/satellite`). v0.5 `x/bridge` handlers implement IBC packet recv/ack for these 5 chains' `BridgeStatus` transitions.

+- 4 v0.4-scope REQs shipped as NFR (refactor/test/docs/chore): REQ-029, REQ-030, REQ-031, REQ-032
+- Closes 3 real v0.3 forward-references: GRILL G-014 (lexicon drift), REVIEW P2/A-304 (const drift), AUDIT §193 (council divergence docs)
+- Lands the D-046 docs-CI forward-reference (.gitea/workflows/docs-build.yml, build+artifact, no Pages publish per D-051)
+- NFR purity gate GREEN: zero `feat:` commit subjects in the milestone (20 commits, all docs/refactor/test/chore/verify/decision/checkpoint/Merge)
+- `go.mod` unchanged (G-006 — zero Go deps; Python deps isolated to CI docs-build job)
+- G-003 production firewall intact (no production import of `x/bond/types` in `x/hub/types`; cross-const test is test-only)
+- Coverage: x/hub/types 93.3% (v0.3 floor preserved), x/council/types 96.4% (improved); both above 80% target
+- Tags: v0.3.0 (P0) -> v0.3.1 (P1) -> v0.3.2 (P2) -> v0.3.3 (P3) -> v0.3.4 (P4 = v0.4 milestone release)
+- Tag-line note: v0.4 (NFR) ships on the v0.3.x patch line (config tag_base). The v0.3.4 milestone release IS the deliverable (D-008 — final phase patch IS the milestone release; no separate minor tag).

+## v0.5 Scope Recap (from D-054..D-061)
+
+v0.5 promotes seven v0.3-era skeleton modules to runtime, plus the council
+governance enum additions deferred from v0.4 (AUDIT §193 P1-1, D-050). The
+promotion pattern is uniform: each module gains a `keeper/` subdir with a
+Cosmos-SDK-style `MsgServer` (message handlers consuming `sdk.Context` +
+the store), `types.Msg*` message types implementing `sdk.Msg` (ValidateBasic +
+GetSigners), and a `simtest/` (or module-internal `*_simtest_test.go`) end-to-
+end flow exercising the handler against an in-memory keeper. The existing
+`types/` packages stay as the lexicon-locked type contracts (their locked
+consts, enums, and structs are NOT amended — the runtime layer adds behavior
+on top, not changes to the contract).
+
+| REQ | Module(s) | Promotion (skeleton → runtime) | Phase (D-056) |
+|---|---|---|---|
+| REQ-033 | `x/exit`, `x/bridge` | DEX swap routing handlers + L2↔L1 IBC packet recv/ack/timeout handlers for the 5 locked L2 chains | P1 |
+| REQ-034 | `x/bearers` | OY-SAT + OY-QR message handlers; session lifecycle in simtest | P2 |
+| REQ-035 | `x/partner` | Anchor tier credential issuance + revocation handlers | P3 |
+| REQ-036 | `x/hub` | Custody / LendingPrimitive / Compliance message handlers; `CustodyKeyring` interface + in-memory test impl | P4 |
+| REQ-037 | `x/services` | Care / SIM / Vault / Mail service lifecycle handlers | P5 |
+| REQ-038 | `x/bond` | Growth Bond issuance + secondary-market CLOB matching handlers; 8% cap / 0% floor per-match clamp (D-057) | P6 |
+| REQ-039 | `x/council` | `Proposal` + `VoteOption` enum types (AUDIT §193 P1-1) + Voice lifecycle handlers; Mission Lock const firewall intact | P7 |
+
+**Dependency direction (D-056):** P1 exit (outermost edge, fewest internal
+deps) → P2 bearers (routes through exit) → P3 anchors (rides bearers) → P4
+hub (custody backs anchors) → P5 services (sits on hub) → P6 bond (uses hub
+lending primitive) → P7 council (cross-cutting, lands last) → P8 final
+review/audit/ship. Each phase independently shippable (vertical-slice
+integrity, same as v0.1..v0.4).
+
+---
+
+## v0.5 §1. Runtime Promotion Pattern — Skeleton-to-Runtime Delta
+
+The v0.3 skeleton baseline (verified against the current tree): each target
+module has only a `types/` subdir containing `types.go` (pure-Go structs +
+locked consts + enums), `genesis.go` (ValidateGenesis), and `*_test.go`
+(invariant + lexicon tests). The in-memory `Keeper` stub lives INSIDE
+`types/types.go` (e.g., `x/partner/types/types.go:101 type Keeper struct{...}`,
+`NewKeeper()` returns `&Keeper{partners: make(map[string]Partner)}`). There
+is NO `keeper/` subdir, NO `msg_server.go`, NO `types.Msg*`, NO `sdk.Context`,
+and NO cosmos-sdk import anywhere in `x/` (grep for `cosmos-sdk` /
+`sdk.Context` / `cosmos/cosmos` returns zero matches — verified).
+
+### v0.5 §1.1 The MsgServer promotion pattern (Cosmos SDK convention)
+
+**Prior art / ecosystem references:**
+- **Cosmos SDK `MsgServer`** — the canonical pattern since cosmos-sdk v0.40+
+  (the Stargate refactor). Each module's `keeper/` package exposes a
+  `MsgServer` struct that wraps the module `Keeper` and implements one method
+  per message type (e.g., `func (ms msgServer) Send(ctx, msg) (*MsgSendResponse,
+  error)`). The `types.Msg*` structs implement `sdk.Msg` (`ValidateBasic()`,
+  `GetSigners()`), are registered with the module's codec, and routed by the
+  base app's `MsgServiceRouter`. This is the universal pre-mainnet step in the
+  Cosmos-SDK module lifecycle (every ibc-go, Osmosis, Celestia, dYdX module
+  follows it).
+- **`types.Msg*` + `ValidateBasic`** — the message validation gate runs
+  statelessly before the handler; `ValidateBasic` rejects malformed messages
+  early (negative amounts, empty ids, invalid enums). The handler then does
+  stateful validation against `sdk.Context` (duplicate-id checks, authz,
+  capacity).
+- **`sdk.Context` + store** — the keeper reads/writes the module's prefixed
+  `sdk.KVStore` via `ctx.KVStore(ms.storeKey)`. The v0.3 in-memory
+  `map[string]T` keeper is replaced by (or wrapped behind) a store-backed
+  keeper; simtest exercises it against an in-memory `commit-db` (the SDK's
+  `dbm` in-memory backend), not a real CometBFT store.
+
+**Skeleton-to-runtime delta (uniform across all 8 target modules):**
+
+| Aspect | v0.3 skeleton | v0.5 runtime |
+|---|---|---|
+| Keeper location | `types/types.go` (in-memory `map[string]T`) | `keeper/keeper.go` (store-backed, wraps `sdk.KVStore`); the v0.3 in-memory stub may stay as a test helper or be retired |
+| Message types | none | `types/msg_*.go` with `Msg*` structs implementing `sdk.Msg` (`ValidateBasic`, `GetSigners`, proto-ish `ProtoMessage` via legacy amino or the SDK's `codec.JSONCodec`) |
+| Message handlers | none | `keeper/msg_server.go` with `MsgServer` + one `*Response, error` method per `Msg*` |
+| Module wiring | none | `module.go` (` AppModuleBasic` / `AppModule` with `RegisterServices` registering the `MsgServer`) — simtest may use a lighter `ModuleManager` shim |
+| End-to-end test | invariant tests only | `simtest/` (or `keeper/msg_server_simtest_test.go`) exercising each handler against an in-memory `sdk.Context` |
+| Dependency | stdlib only | `github.com/cosmos/cosmos-sdk` (+ transitive) per D-055 (GRILL-approved controlled exception to G-006) |
+
+**Pitfall — state machine ordering:** the handler must do stateful validation
+in a stable order (authz → capacity/lock → state transition → event emit).
+Reordering causes double-spend / replay. The Cosmos-SDK convention is:
+(1) `ValidateBasic` (stateless, in the msg), (2) keeper authz check, (3)
+state mutation under the store, (4) `ctx.EventManager().EmitEvent(...)`. Each
+v0.5 handler follows this order; simtest asserts the event is emitted and the
+state is durably written.
+
+**Pitfall — replay protection:** `sdk.Msg` carries `GetSigners()`; the base
+app deduplicates by tx hash + sequence. For messages that MUST be one-shot
+(e.g., OY-QR consume, Anchor credential revocation, bond matching fill), the
+handler additionally flips an idempotency flag in state (e.g., `consumed =
+true` on the OYQRCode, already in the v0.3 skeleton) so a replayed tx is a
+no-op rather than a double-effect. This mirrors ibc-go's packet-replay
+protection (the sequence + packet-commitment pair).
+
+**Confidence (planner-relevant):**
+- A-501: every v0.5 target module gains a `keeper/` subdir + `msg_server.go`,
+  leaving the existing `types/` package as the locked-contract layer. **0.92**
+- A-502: the v0.3 in-memory `Keeper` stub (in `types/types.go`) is retained
+  as a test-only construct or replaced by the store-backed keeper; the
+  `types/` package's public API is NOT broken (no struct field removal). **0.80**
+- A-503: simtest uses the SDK in-memory store (not a real CometBFT node);
+  no live chain, no real IBC light clients (D-054). **0.90**
+
+---
+
+## v0.5 §2. Per-REQ Runtime Research
+
+### v0.5 §2.1 REQ-033 — Exit + Bridge runtime (P1)
+
+**What it is:** `x/exit` gains DEX swap routing handlers
+(`MsgSubmitExitRoute` → status transitions through the v0.3 `ExitStatus`
+enum; `MsgExecuteDEXSwap` → venue-hop execution producing a `DEXSwap` record
+and a `Settled`/`Failed`/`Refunded` terminal state). `x/bridge` gains L2↔L1
+IBC packet handlers for the 5 locked L2 chains (Polygon/Base/Arbitrum/
+Optimism/Solana per REQ-009/D-059): `OnRecvPacket`, `OnAcknowledgementPacket`,
+`OnTimeoutPacket` driving the v0.3 `BridgeStatus` lifecycle (Pending →
+Attested → Active → Closed).
+
+**Prior art / ecosystem references:**
+- **ibc-go `IBCModule` / `applications/transfer`** — the canonical
+  application-layer pattern: a module implements
+  `ibcapp.PacketExecutor` (v2) or the legacy `IBCModule` interface
+  (`OnRecvPacket`, `OnAcknowledgementPacket`, `OnTimeoutPacket`,
+  `OnChanOpenInit/Confirm/Ack`). IBC v2 (ibc-go v10, D-021's reference) uses
+  typed `Payload`s and timestamp-only timeouts; the recv handler returns an
+  acknowledgement byte sequence (the "ack"); a failed ack is non-replayable.
+  OY's `x/bridge` recv handler mirrors this contract but operates on the
+  v0.3 `BridgeRoute` + a payload shape pinned to ICS-20 v1 (the v0.2
+  satellite packet shape).
+- **IBC Eureka** — ibc-go v10's Eureka path (Cosmos↔Ethereum-style) is
+  relevant for the 4 EVM L2 chains (Polygon/Base/Arbitrum/Optimism); the
+  timestamp-only timeout model avoids the height-timeout ambiguity that
+  breaks EVM chains without a reliable block-height clock.
+- **Wormhole-style adapter for Solana** — Solana lacks native IBC (v0.1
+  RESEARCH §1.1; D-021). D-059 promotes the v0.1 stubbed wormhole-style
+  adapter to a runtime handler: Solana packets are recv'd via a
+  wormhole-portal-shaped envelope (VAA — Verified Action Approval) and the
+  `x/bridge` handler verifies the guardian signature set (a 2-of-N quorum,
+  N being the wormhole guardian set) before transitioning the route. The
+  adapter is typed in v0.3 (bridge-type opaque string "wormhole"); v0.5
+  adds the verification handler. No live wormhole integration (D-054) — the
+  simtest uses a stub guardian set.
+- **DEX routing** — 1inch / 0x API / Paraswap path optimization is the off-
+  chain analog; the on-chain handler executes a PRE-COMPUTED hop sequence
+  (the v0.3 `ExitRoute.venue-hops []string`), it does not run an off-chain
+  pathfinder. dYdX v4 / Sei v2 execute pre-routed swaps similarly.
+
+**Skeleton-to-runtime delta:**
+- `x/exit`: v0.3 had `ExitRoute` + `DEXSwap` structs + `ExitStatus` enum +
+  keeper stub (AddExitRoute/GetExitRoute/ListByHolder). v0.5 adds
+  `MsgSubmitExitRoute`, `MsgExecuteDEXSwap`, `MsgRefundExit` (on Failed)
+  implementing `sdk.Msg`; a `keeper/msg_server.go` with the three handlers
+  driving status transitions; a simtest asserting the full
+  Proposed→InProgress→Settled/Failed/Refunded path. The `bridge-route-id`
+  field (by-ID-string ref to x/bridge per G-003) is now ACTED on: a cross-
+  chain exit invokes the `x/bridge` recv path (via the module's keeper
+  interface, NOT a struct import — the G-003 by-ID-string rule survives the
+  runtime promotion; the keeper-to-keeper call uses a typed interface defined
+  in a shared `types/expected_keepers.go` shim, the ibc-go convention).
+- `x/bridge`: v0.3 had `BridgeRoute` + `BridgeStatus` enum + keeper stub.
+  v0.5 adds `MsgAttestBridgeRoute` (Watcher-quorum-driven transition
+  Pending→Attested, referencing `x/watcher` by ID), `MsgActivateBridge`,
+  `MsgCloseBridge`, and the IBC trio `OnRecvPacket` / `OnAcknowledgementPacket`
+  / `OnTimeoutPacket`. The recv handler parses the ICS-20 v1 payload
+  (denom, amount, sender, receiver), validates the denom trace against the
+  v0.2 `WrappedBreadDenom`, and mints/releases wrapped Bread via the
+  `x/bread` keeper interface (expected-keeper shim). Solana packets go
+  through the wormhole-adapter verification branch.
+
+**Pitfalls:**
+- **IBC ack/timeout handling:** a timeout MUST revert the escrow (ibc-go's
+  `OnTimeoutPacket` refunds the source-chain escrow). Forgetting the refund
+  is a classic ibc-go bug class (CVE-class). The simtest MUST include a
+  timeout-replay case asserting the escrow is refunded exactly once.
+- **Ack idempotency:** a duplicate ack (relayer replay) must be a no-op;
+  ibc-go tracks the packet commitment and deletes it on ack, so a second ack
+  finds no commitment and returns. v0.5's handler must mirror this (delete
+  the in-flight record on first ack; reject on second).
+- **Denom trace drift:** if the `WrappedBreadDenom` parsing diverges from
+  ibc-go's `Denom.Trace` path-split, the bridge mis-attributes wrapped
+  tokens. Pin the trace parser to the v0.2 satellite shape (ICS-20 v1,
+  `transfer/channel-N/<denom>`).
+- **Solana adapter signature-set rotation:** the wormhole guardian set
+  rotates; the handler must read the CURRENT guardian set from state, not a
+  hardcoded one. Simtest uses a frozen guardian set; a rotation test is a
+  later concern (deferred, D-054).
+
+**Confidence-scored conclusions:**
+- A-511: `x/bridge` IBC handlers implement the ibc-go `OnRecvPacket` /
+  `OnAcknowledgementPacket` / `OnTimeoutPacket` contract operating on the
+  v0.3 `BridgeRoute` + ICS-20 v1 payload; Solana via the wormhole-adapter
+  branch. **0.82**
+- A-512: keeper-to-keeper cross-module calls use `expected_keepers.go`
+  interface shims (ibc-go convention), NOT struct imports — G-003 by-ID-
+  string rule is preserved at the type level; the runtime adds interface-
+  typed keeper dependencies. **0.85**
+- A-513: IBC ack/timeout replay protection mirrors ibc-go (delete-on-ack,
+  refund-on-timeout); the simtest MUST cover both replay and timeout-refund
+  cases. **0.90**
+
+---
+
+### v0.5 §2.2 REQ-034 — Bearers transport runtime (P2)
+
+**What it is:** `x/bearers` gains OY-SAT and OY-QR message handlers
+(`MsgSendOYSATFrame`, `MsgReceiveOYSATFrame`, `MsgIssueOYQR`, `MsgConsumeOYQR`)
+and a session-lifecycle keeper. Hardware integration is deferred (D-054);
+runtime = message-handling + session lifecycle in simtest. The v0.3
+`OYSATLink` / `OYQRCode` structs (with the `surveillance-resistant` locked
+flag and the one-shot `consumed` flag) become the handler state objects.
+
+**Prior art / ecosystem references:**
+- **Session lifecycle in messaging transports** — XMTP / Session /
+  Matrix (DTN-style store-and-forward) model a session as a sequence of
+  frames bound by a session-id, with send/receive/deliver states. OY's
+  bearer session is closest to a DTN bundle (RFC 5050) with a ttl + a
+  delivery-confirmation ack. The `BearerTransport` interface (v0.2 stub)
+  gains a `Send`/`Receive`/`Status` runtime impl backed by the keeper store.
+- **Bearer token revocation** — OAuth 2.0 token revocation (RFC 7009):
+  a token can be revoked before expiry. OY's session has a `Revoke` handler
+  (mirrors the v0.2 Window `Revoke`); a revoked session rejects further
+  `Receive` calls. Macaroon caveat revocation (Google macaroons) is the
+  closest ocap analog.
+- **One-shot QR / NFC bearer** — Bolt Card (NFC + QR Lightning) is the
+  closest production analog: a QR/NFC payload is consumed on first scan;
+  a replay is rejected. The v0.3 `OYQRCode.consumed` flag is the runtime
+  idempotency gate; the `MsgConsumeOYQR` handler flips it atomically.
+- **Surveillance-resistant transports** — Helium (LoRa coverage, public),
+  Nodle (BLE mesh), B.A.T.M.A.N. routing. OY-LR/OY-SAT are surveillance-
+  resistant (vision §14, locked flag); the handler does NOT log
+  geolocation or sender identity beyond the reach-id (the lexicon-clean
+  holder identifier). The `surveillance-resistant` const is a runtime
+  invariant (a handler that emits geolocation data violates it).
+
+**Skeleton-to-runtime delta:**
+- v0.3: `OYSATLink` + `OYQRCode` structs + `BearerTransport` interface
+  (shape stubs, no impl) + locked-const test that `BearerOYSAT` /
+  `BearerOYQR` are in `AllBearers()` (6 bearers, locked since v0.1).
+- v0.5: a `keeper/` with `MsgServer` implementing the four messages; a
+  `Session` struct (session-id, bearer-type, initiator-reach, peer-reach,
+  status [Open/Active/Closed/Revoked], frames []Frame, ttl, opened-at,
+  closed-at) stored under the keeper; the `BearerTransport` interface gains
+  a store-backed impl (the keeper IS the transport for simtest purposes —
+  no hardware). `MsgConsumeOYQR` is the canonical one-shot handler: it
+  loads the QR, asserts `!consumed`, asserts `expires-at > now`, flips
+  `consumed`, emits the transfer effect (a `x/bread` grain transfer via
+  the expected-keeper shim), emits an event, returns. A replay finds
+  `consumed == true` and returns an error (idempotent reject, not double-
+  effect).
+
+**Pitfalls:**
+- **Session state machine ordering:** Open → Active (on first frame ack) →
+  Closed (on last frame or ttl expiry) → Revoked (out-of-band). A frame
+  received on a Closed/Revoked session MUST be rejected. Simtest covers all
+  four transitions + the rejected-frame case.
+- **One-shot replay:** the `consumed` flag is the only replay firewall for
+  OY-QR. If the handler does the transfer BEFORE flipping `consumed`, a
+  crash between the two leaves a double-spend window. The handler MUST flip
+  `consumed` FIRST (state write), THEN do the transfer (the SDK store is
+  atomic per tx — a panic rolls back the whole tx, so the order is safe;
+  but the order documents intent and matches the ibc-go delete-before-mint
+  convention).
+- **Surveillance-resistance invariant:** the `surveillance-resistant`
+  const is a compile-time lock; a runtime handler that emits a
+  geolocation event or logs the sender's physical location violates the
+  spirit. Simtest asserts the event set contains NO geolocation fields
+  (a negative test).
+- **Lexicon:** "session", "frame", "bearer", "QR", "SAT" are lexicon-safe.
+  Avoid "account"/"deposit" (use reach-id/Stash by ID).
+
+**Confidence-scored conclusions:**
+- A-521: OY-QR is one-shot; `MsgConsumeOYQR` flips `consumed` before the
+  transfer effect; replay is rejected idempotently. **0.88**
+- A-522: the `BearerTransport` interface gains a store-backed impl (the
+  keeper acts as the transport in simtest); no hardware/RF dep is added
+  (D-054). **0.85**
+- A-523: session lifecycle mirrors Window's lifecycle (Open/Active/Closed/
+  Revoked) for consistency with the v0.2 Window primitive. **0.78**
+

+
+### v0.5 §2.3 REQ-035 — Anchors onboarding runtime (P3)
+
+**What it is:** `x/partner` Anchor tier gains credential issuance and
+revocation handlers. The v0.3 `AnchorCredential` struct (partner-id,
+jurisdiction, custody-provider-id, attestation-refs, onboarded-at) becomes
+the state object of a credential lifecycle: `Pending → Onboarded →
+Suspended → Revoked` (reusing the v0.2 PartnerStatus 4-state shape).
+
+**Prior art / ecosystem references:**
+- **Verifiable Credential lifecycle** — W3C VC Data Model ( issuance →
+  verification → revocation); the revocation is the highest-risk operation
+  (a revoked credential used post-revocation is a fraud vector). OY's
+  revocation handler flips the status; downstream consumers (hub custody,
+  services) check the status before acting.
+- **Institutional onboarding** — MakerDAO RWA arrangers (legal repr +
+  off-chain agreements), Centrifuge tier sponsors, Maple underwriting,
+  Ondo institutional wrappers. OY's Anchor is the protocol-level abstraction;
+  the v0.5 runtime is the credential lifecycle, NOT the real off-chain
+  legal onboarding (deferred).
+- **Credential revocation lists** — CRL (X.509), OCSP (online status),
+  Verifiable Credential revocation (BitstringStatusList). OY's keeper
+  stores the status in-state; downstream queries check the keeper (an
+  OCSP-like online check, no separate CRL distribution).
+
+**Skeleton-to-runtime delta:**
+- v0.3: `AnchorCredential` struct + `Keeper.AddAnchorCredential` /
+  `ListByTier(TierAnchor)` stub (in-memory).
+- v0.5: `MsgIssueAnchorCredential` (issuer must be a Watcher-authorized
+  onboarding party — checked via the `x/watcher` expected-keeper shim by
+  ID; the credential starts `Pending`), `MsgOnboardAnchor` (transitions to
+  `Onboarded` after attestation-refs are populated + custody-provider-id is
+  set — the hub custody service must exist, checked via the `x/hub`
+  expected-keeper shim by ID), `MsgSuspendAnchorCredential`, `MsgRevokeAnchor
+  Credential` (only a Watcher quorum or the issuing party can revoke —
+  authz via the watcher shim). Simtest covers the full lifecycle and the
+  post-revocation rejection (a downstream custody action on a revoked
+  credential returns `ErrCredentialRevoked`).
+
+**Pitfalls:**
+- **Revocation race:** a credential revoked while a custody action is in-
+  flight. The handler checks status at tx start; the SDK store is atomic
+  per tx, so a concurrent revocation is serialized (one tx wins). Simtest
+  covers the revoked-during-action case (the action sees the post-revocation
+  status because txs are serial).
+- **Authz:** who can issue / revoke is a Watcher concern (6-of-9 quorum,
+  REQ-004). The handler delegates the authz check to the `x/watcher`
+  expected-keeper interface; it does NOT import `x/watcher/types` (G-003
+  intact). The interface is defined in `x/partner/types/expected_keepers.go`.
+- **Custody-provider-id validity:** the `OnboardAnchor` handler asserts
+  the custody-provider-id references a live `x/hub` custody service. This
+  is a P3→P4 cross-phase edge (anchors P3 depend on hub P4). D-056 orders
+  P3 before P4, so the hub custody keeper interface must EXIST (as a shim)
+  before P3, even if the hub runtime lands in P4. The shim is a typed
+  interface in `x/partner/types/expected_keepers.go`; the real impl is
+  wired in P4. This is the standard ibc-go "expected keepers" pattern for
+  breaking cross-module dep cycles.
+
+**Confidence-scored conclusions:**
+- A-531: Anchor credential lifecycle = Pending → Onboarded → Suspended →
+  Revoked (reusing the v0.2 PartnerStatus 4-state shape). **0.82**
+- A-532: the P3→P4 hub dependency is broken by an `expected_keepers.go`
+  interface shim (ibc-go convention); the hub runtime impl is wired in P4.
+  **0.85**
+- A-533: revocation authz delegates to the `x/watcher` expected-keeper
+  shim (6-of-9 quorum check); no `x/watcher/types` struct import (G-003
+  intact). **0.88**
+
+---
+
+### v0.5 §2.4 REQ-036 — Hub API B2B runtime (P4)
+
+**What it is:** `x/hub` gains custody / lending-primitive / compliance
+message handlers. The v0.3 `HubService` enum (3 services) + per-service
+struct stubs become the state objects of service lifecycle + per-service
+operations. The custody service introduces the `CustodyKeyring` interface
+(D-058) with an in-memory test-only impl.
+
+**Prior art / ecosystem references:**
+- **Custody keyring abstractions** — Fireblocks / Anchorage / BitGo expose
+  MPC / HSM-backed signing via an API; the chain-side abstraction is a
+  `Keyring` interface (`Sign`, `Derive`, `PubKey`). Cosmos SDK has a
+  `crypto.Keyring` interface (used for validator keys) — OY's
+  `CustodyKeyring` is a sibling interface scoped to custody assets, NOT
+  validator keys. The MPC vendor abstraction is the same shape: the chain
+  does not hold the private key; it holds a handle that delegates signing
+  to the MPC cluster. OY's v0.5 ships the interface + an in-memory test
+  impl (a `memKeyring` that signs with a throwaway ed25519 key); real MPC
+  is operational, Year 3+.
+- **B2B API backbones** — Stripe API (modular resources), Plaid (the
+  anti-bank analog is structural only), Coinbase Prime (institutional
+  custody + prime). OY's hub is the on-chain B2B service registry; the
+  handlers are the on-chain operations, the off-chain B2B integration is
+  deferred.
+- **Lending primitive** — Aave / Compound protocol-level lending; OY's
+  lending primitive is a Hub-service type, the protocol-level primitive
+  (not a live market). The 8% cap / 0% floor (D-028) is cross-documented as
+  the local consts `LendingCouponCapBps = 800` / `LendingCouponFloorBps = 0`
+  (v0.3, A-304); v0.5's lending handler CLAMPS the coupon to this band per
+  operation (the REQ-030 cross-const test already guards drift between hub
+  and bond consts; the v0.5 handler asserts the clamp at runtime too).
+- **Compliance** — on-chain compliance attestations (TRM Labs, Elliptic,
+  Chainalysis). OY's compliance service handler records an attestation ref
+  (opaque URI) against a partner; a downstream custody action checks the
+  compliance status before acting.
+
+**Skeleton-to-runtime delta:**
+- v0.3: `HubService` enum (3) + `HubServiceInfo` + per-service structs
+  (`CustodyService`, `LendingPrimitiveService`, `ComplianceService`) +
+  keeper stub (AddService/GetService/ListByKind) + local consts
+  `LendingCouponCapBps`/`LendingCouponFloorBps` (cross-documented to
+  D-028).
+- v0.5: `CustodyKeyring` Go interface in `x/hub/types/keyring.go`:
+  ```go
+  type CustodyKeyring interface {
+      Sign(ctx context.Context, assetID string, payload []byte) ([]byte, error)
+      Derive(ctx context.Context, assetID string) (PubKey, error)
+      Status(ctx context.Context, assetID string) (KeyringStatus, error)
+  }
+  ```
+  + `memKeyring` impl (test-only, in `x/hub/keeper/keyring_mem.go` or
+  `x/hub/types/keyring_mem_test.go`). Handlers: `MsgRegisterCustodyService`
+  (operator must be an Onboarded Anchor — checked via `x/partner`
+  expected-keeper shim), `MsgDepositCustodyAsset` (delegates signing to the
+  `CustodyKeyring` — the in-memory impl returns a stub signature; the
+  handler records the custody entry + the sig ref), `MsgWithdrawCustodyAsset`
+  (authz: only the holder or an authorized Window grantee; checks
+  compliance status via the compliance expected-keeper shim),
+  `MsgRecordLendingPrimitive` (clamps coupon to [LendingCouponFloorBps,
+  LendingCouponCapBps] — the runtime echo of the D-028 / REQ-030 firewall),
+  `MsgRecordComplianceAttestation`.
+
+**Pitfalls:**
+- **Custody key rotation:** the `CustodyKeyring` interface MUST support a
+  rotation (a new key takes over for an assetID). The in-memory impl can
+  rotate trivially (swap the keymap entry); the interface shape must allow
+  it (the `Status` method reports the active key version). A handler that
+  caches the pubkey across txs breaks rotation — keepers are per-tx, so
+  the keyring is consulted per operation (no caching across blocks).
+- **Compliance-before-custody ordering:** a withdrawal on a non-compliant
+  partner MUST be rejected. The handler checks compliance status BEFORE the
+  custody debit; reversing creates a withdrawal-then-reject race (the debit
+  lands, the reject fires after). Same state-machine-ordering pitfall as
+  the general handler pattern (§1.1).
+- **Coupon clamp at runtime:** the lending handler clamps the coupon; if a
+  later change moves the consts (a locked-const amendment, which is
+  rejected by the Mission Lock firewall), the handler's clamp silently
+  uses the new value. The REQ-030 cross-const test catches drift between
+  hub and bond consts; the v0.5 handler additionally emits an event with
+  the clamped value so simtest can assert the clamp ran.
+- **Lexicon:** "custody", "lending", "coupon", "compliance" are safe.
+  "interest"/"yield"/"deposit"/"savings" banned (use coupon/lending/
+  custody/grain). The `MsgDepositCustodyAsset` name is borderline —
+  "deposit" is banned. **Rename to `MsgCustodyReceiveAsset`** to keep the
+  message type name lexicon-clean. (This is a v0.5 discovery; the v0.3
+  struct fields use "custody" safely, but the message name must not import
+  "deposit".)
+
+**Confidence-scored conclusions:**
+- A-541: `CustodyKeyring` interface (`Sign`/`Derive`/`Status`) +
+  `memKeyring` in-memory test impl; real MPC/HSM deferred. **0.88**
+- A-542: the custody message names AVOID the banned "deposit" (use
+  `MsgCustodyReceiveAsset` / `MsgCustodyReleaseAsset`); the v0.3 struct
+  fields stay (they already use "custody"). **0.85**
+- A-543: lending handler clamps the coupon to [0, 800] bps at runtime
+  (D-028/REQ-030 runtime echo); the clamp event is emitted for simtest. **0.82**
+- A-544: compliance-before-custody ordering is enforced (the withdrawal
+  handler checks compliance status before the custody debit). **0.85**
+

+
+### v0.5 §2.5 REQ-037 — Services runtime (P5)
+
+**What it is:** `x/services` gains Care / SIM / Vault / Mail service
+lifecycle handlers. The v0.3 `ServiceKind` enum (4) + `ServiceInfo` + per-
+service structs become the state objects of a service lifecycle: `Pending →
+Active → Suspended → Revoked` (reusing the 4-state shape from v0.2
+PartnerStatus / v0.3 HubServiceStatus).
+
+**Prior art / ecosystem references:**
+- **Service registry patterns** — Kubernetes Service (a logical name +
+  endpoints), Consul / etcd service discovery, Cosmos SDK `x/params` (a
+  light registry). OY's services are a typed registry: a service has a
+  kind, an operator, a status, and a window-id grant (the v0.3
+  `ServiceInfo.window-id` field, by-ID-string ref to `x/window`).
+- **Care / mutual-aid** — Gitcoin Grants rounds (care as public-good
+  funding); OY Care is a community-care service a Stand/Guild operates.
+- **SIM / connectivity** — Helium Mobile (DePIN connectivity), Pollen,
+  Andrena. OY SIM is a connectivity service; the handler records a SIM
+  activation against a window-grant.
+- **Vault / storage** — the v0.2 `x/vault` is the Stand-level storage pool;
+  the OY Vault service (ServiceKind=Vault) is a higher-level storage
+  offering (backup, attested storage). The handler references `x/vault`
+  by ID-string (G-003).
+- **Mail / messaging** — Session, Status, XMTP (decentralized messaging);
+  OY Mail is a bearer-routed messaging service. The handler records a
+  mailbox binding against a window-grant.
+
+**Skeleton-to-runtime delta:**
+- v0.3: `ServiceKind` enum (4) + `ServiceInfo` + per-service structs +
+  keeper stub.
+- v0.5: `MsgRegisterService` (operator-reach-id must be valid; the
+  `window-id` must reference an Active Window — checked via the `x/window`
+  expected-keeper shim), `MsgActivateService`, `MsgSuspendService`,
+  `MsgRevokeService` (revocation requires the Window grantor or a
+  Watcher quorum). Per-kind handlers: `MsgIssueCareGrant` (Care),
+  `MsgActivateSIM` (SIM), `MsgProvisionVault` (Vault, references `x/vault`
+  by ID), `MsgBindMailbox` (Mail). Simtest covers the lifecycle + the
+  window-grant check (a service registered against a non-existent or
+  Revoked Window is rejected).
+
+**Pitfalls:**
+- **Window-grant validity:** the `window-id` is the service's authority
+  boundary; a revoked Window invalidates the service. The handler checks
+  the Window status on every operation (not just registration) — a service
+  operating after its Window expired is a Window-violation. Simtest covers
+  the expired-window-during-operation case.
+- **Service-kind dispatch:** the per-kind handlers are distinct messages
+  (`MsgActivateSIM` vs `MsgBindMailbox`); a generic `MsgInvokeService(kind,
+  payload)` would be a type-unsafe dispatch (a kind mismatch is a runtime
+  error, not a compile-time one). The v0.5 handlers are per-kind (one Msg
+  per ServiceKind) to keep the dispatch typed. This mirrors the v0.3
+  per-service struct pattern.
+- **Coverage:** services are the lowest-priority REQ (Medium); the
+  ≥80% coverage target (D-033 carries forward) is achievable with table-
+  driven handler tests per kind.
+
+**Confidence-scored conclusions:**
+- A-551: per-kind message handlers (one `Msg*` per ServiceKind), NOT a
+  generic dispatch — keeps the dispatch typed. **0.80**
+- A-552: the `window-id` grant is checked on EVERY service operation, not
+  just registration (a revoked Window invalidates ongoing service ops). **0.82**
+- A-553: Vault service references `x/vault` by ID-string (G-003); the
+  handler uses an `expected_keepers.go` shim for the vault keeper. **0.85**
+

+
+### v0.5 §2.6 REQ-038 — Bond market depth runtime (P6)
+
+**What it is:** `x/bond` gains Growth Bond issuance handlers and a
+secondary-market **central-limit order book (CLOB)** matching engine
+(D-057). The 8% cap / 0% floor consts (D-028, locked since v0.2) are a
+**hard per-match clamp**: every match's resulting coupon stays within
+[0, 800] bps. No AMM (D-057 rejects AMM as a Year-4 concern).
+
+**Prior art / ecosystem references:**
+- **CLOB matching engines** — dYdX v4 (a fully on-chain CLOB in a Cosmos
+  app-chain, price-time priority, batch matching), Sei v2 (order-book
+  matching with parallel execution), 0x Mesh (off-chain order relay +
+  on-chain settlement). OY's CLOB is closest to dYdX v4's per-tx matching
+  (the handler matches a new order against the resting book in the same
+  tx; no asynchronous matching). The matching is price-time priority (FCFS
+  at the same price — REQ-007 FCFS principle).
+- **Fixed-income secondary markets** — Centrifuge Tinlake secondary
+  (tokenized tranches trade on an order book); OY's secondary market
+  trades issued bonds (the v0.3 `SecondaryOrder` struct, Buy/Sell side).
+- **Coupon caps as per-match clamp** — the 8% cap (D-028) is mission-
+  locked; the matching engine enforces it PER MATCH (the matched
+  coupon is clamped to [0, 800] before the trade record is written). This
+  is distinct from a market-wide price cap: the secondary-market TRADE
+  PRICE (the fraction of principal) is market-determined, but the bond's
+  COUPON stays in the locked band. A trade that would imply a coupon
+  above 800 bps is rejected (or the coupon is clamped to 800 and the
+  excess is refunded — design choice, see pitfall below).
+- **Growth Bond coupon growth** — the v0.3 `GrowthBond.GrowthRateBps` +
+  `ClampGrowth` helper ensure the post-growth coupon ≤ 800. v0.5's
+  issuance handler invokes `ClampGrowth` at issuance and on each growth
+  tick (a `MsgTickGrowthBond` handler, simtest-driven, not real-time).
+
+**Skeleton-to-runtime delta:**
+- v0.3: `Bond` + `GrowthBond` + `SecondaryOrder` structs + `OrderSide`/
+  `OrderStatus` enums + `Clamp`/`ClampGrowth` helpers + keeper stub
+  (AddOrder/GetOrder/ListByBond/CancelOrder — no matching).
+- v0.5: `MsgIssueBond`, `MsgIssueGrowthBond` (invokes `Clamp` on the
+  coupon, then `ClampGrowth` if a growth rate is set), `MsgTickGrowthBond`
+  (applies the growth, clamped), `MsgPlaceSecondaryOrder` (Buy/Sell side,
+  price in bps, quantity in grain), `MsgCancelSecondaryOrder`,
+  `MsgMatchSecondaryOrder` (the CLOB match: loads the resting book for
+  the bond, matches the new order against the best opposing price until
+  filled or the book is empty, writes `Filled` orders, emits a match
+  event with the matched coupon clamped to [0, 800]). The matching is
+  price-time priority (FCFS at the same price — REQ-007). Simtest covers:
+  full fill, partial fill + rest, no-match (order rests), cancel, and the
+  clamp-on-match (a match that would imply coupon > 800 is clamped, the
+  excess refunded or rejected — see pitfall).
+
+**Pitfalls:**
+- **CLOB front-running:** in a single-validator simtest there is no MEV;
+  but the handler design must not ENABLE front-running in a real chain.
+  The dYdX v4 pattern (batch matching at end-of-block) mitigates MEV; OY's
+  v0.5 is per-tx matching (simtest only), but the handler MUST be
+  documented as NOT front-running-safe for mainnet (a Year-3+ concern).
+  The simtest does NOT assert front-running safety (it's out of scope for
+  simtest-grade runtime per D-054).
+- **Per-match clamp semantics:** two designs — (a) REJECT a match whose
+  implied coupon exceeds 800 (the trade fails, the order rests), or (b)
+  CLAMP the coupon to 800 and refund the excess to the seller. D-057 says
+  "hard clamp on each match"; "clamp" suggests (b), but rejecting is
+  simpler and safer (no refund path). **Recommendation: REJECT** (the
+  match fails closed; the resting order stays). This matches the Fee
+  Covenant's `Clamp` shape (which clamps, not rejects) for issuance, but
+  for matching the reject is the mission-lock-true choice (a trade above
+  the cap is a usury violation, not a clampable excess). Flag as a
+  planner decision (D-057 is "clamp"; the runtime interpretation is
+  "reject above cap, clamp within band"). **Confidence 0.70** — the
+  planner should resolve reject-vs-clamp before P6.
+- **Mission-lock const firewall:** the 8%/0% consts (D-028) are the
+  highest-severity locked consts in the bond module. The matching handler
+  MUST reference the consts (not a local copy); the v0.3 `Clamp` already
+  uses the consts; the v0.5 match handler reuses `Clamp` on the matched
+  coupon. The REQ-030 cross-const test (hub lending consts == bond consts)
+  stays green.
+- **FCFS at same price:** REQ-007 mandates FCFS. The CLOB matches at
+  price-time priority: at the same price, the earlier resting order
+  fills first (by sequence). The keeper stores the resting book ordered
+  by (price, sequence); the match iterates in that order.
+- **Lexicon:** "coupon", "growth", "secondary", "order", "match", "fill",
+  "cancel" are safe. "interest"/"yield"/"deposit"/"savings" banned. The
+  `MsgTickGrowthBond` handler is the lexicon risk ("growth" is safe;
+  "tick" is safe).
+
+**Confidence-scored conclusions:**
+- A-561: CLOB matching with price-time priority (FCFS at same price per
+  REQ-007); per-tx matching in simtest (dYdX-v4-shaped, no batch
+  end-of-block matching in v0.5). **0.82**
+- A-562: per-match coupon clamp to [0, 800] bps via the v0.3 `Clamp`
+  helper; a match above 800 is REJECTED (fails closed), not clamped-with-
+  refund (the safer mission-lock-true choice). **0.70** — planner to
+  confirm reject-vs-clamp before P6.
+- A-563: the 8%/0% consts are referenced directly (not copied); the
+  REQ-030 cross-const test stays green. **0.90**
+- A-564: no AMM (D-057); the CLOB is the only matching engine in v0.5. **0.95**

+
+### v0.5 §2.7 REQ-039 — Council governance runtime (P7)
+
+**What it is:** `x/council` gains `Proposal` and `VoteOption` enum types
+(AUDIT §193 P1-1, deferred from v0.4 by D-050/D-001) and Voice lifecycle
+handlers. `SignalKind` stays at 4 sources (P1-2 defensible per AUDIT;
+expansion to 5 deferred to v0.6+ governance vote). Mission Lock const
+firewall (G-003) intact — `MissionLockAmendable = false` is unchanged.
+
+**Prior art / ecosystem references:**
+- **Governance proposal lifecycle** — OpenZeppelin Governor (Pending →
+  Active → Succeeded → Queued → Executed → Defeated), Compound Bravo,
+  Cosmos SDK `x/gov` (`ProposalStatus`: DepositPeriod → VotingPeriod →
+  Passed → Rejected → Failed). OY's council governance is a federated
+  variant (three councils, each with its own voter base); D-060 specifies
+  `ProposalKind` = {Stand, Guild, Mesh, MissionLockAmendment-Rejected}
+  (the last value exists but the handler REJECTS it — documenting the
+  non-amendability in code). This mirrors `x/gov`'s `ProposalType` but
+  with the Mission-Lock rejection encoded as a kind.
+- **VoteOption enum** — `x/gov` uses {Yes, No, NoWithVeto, Abstain};
+  OZ Governor uses {For, Against, Abstain}. D-060 specifies {Yes, No,
+  Abstain, Veto} where Veto is Watcher-only (a quorum rule). The
+  `TallyResult` (v0.2, already x/gov-shaped with `NoWithVeto` kept as a
+  zero-locked field) is reused; the Veto option populates the
+  `NoWithVeto` field (it was zero-locked in v0.2 because there was no
+  VoteOption enum; v0.5 un-locks it to a Watcher-only option, but the
+  ANTI-GREED principle means a single Veto does NOT block — it requires
+  a Watcher quorum, not a single veto). This is a careful un-locking:
+  the v0.2 `NoWithVeto` field was `0` always; v0.5 lets Watchers cast
+  it, but the tally rule is quorum-based, not single-veto.
+- **Mission Lock const firewall** — MakerDAO's immutable governance
+  pauses (the "End" / "ESM" emergency shutdown is one-way); Compound's
+  governor has a `Guardian` that can pause. OY's Mission Lock is a
+  compile-time `const bool MissionLockAmendable = false` (v0.2); the v0.5
+  `ProposalKind.MissionLockAmendment-Rejected` handler asserts the
+  const is false and rejects the proposal (the const is the firewall; the
+  handler is the documentation). A future agent flipping the const breaks
+  the v0.2 `TestMissionLockAmendableFalse` test (the regression firewall).
+- **DAO dao / Aragon** — modular governance with proposal + vote + tally
+  + execution; the execution step is the key (OY's v0.5 ships up to the
+  tally; execution of a passed proposal is a v0.6+ concern, deferred —
+  the v0.5 handler records the result but does NOT auto-execute).
+
+**Skeleton-to-runtime delta:**
+- v0.3/v0.4: `Council` + `CouncilMember` + `Voice` + `SignalKind` (4) +
+  `TallyResult` + `MissionLockAmendable = false` const. NO `Proposal` /
+  `ProposalStatus` / `VoteOption` (AUDIT §193 P1-1 absence).
+- v0.5: ADD `Proposal` struct (proposal-id, council-id, kind
+  (ProposalKind), proposer-reach, submit-time, voting-deadline, status
+  (ProposalStatus), tally (TallyResult)). ADD `ProposalKind` enum {Stand,
+  Guild, Mesh, MissionLockAmendment-Rejected} with a locked-const
+  `ProposalKindCount = 4` (the last value is the rejected kind — its
+  existence documents the non-amendability; the handler rejects it). ADD
+  `ProposalStatus` enum {Pending, Active, Succeeded, Failed, Executed}
+  with `ProposalStatusCount = 5` (mirrors OZ Governor / x/gov). ADD
+  `VoteOption` enum {Yes, No, Abstain, Veto} with `VoteOptionCount = 4`
+  (Veto is Watcher-only; the handler checks the signer is a Watcher via
+  the `x/watcher` expected-keeper shim). ADD handlers: `MsgSubmitProposal`
+  (validates kind; MissionLockAmendment-Rejected kind is recorded as
+  Pending but auto-transitions to Failed with an event "Mission Lock
+  non-amendable" — OR the ValidateBasic rejects it; design choice, see
+  pitfall), `MsgVote` (cast a Voice with a VoteOption; Veto requires
+  Watcher authz), `MsgTallyProposal` (closes the voting deadline,
+  computes the tally, transitions Succeeded/Failed). `SignalKind` stays
+  at 4 (P1-2 defensible; the v0.4 regression-guard test
+  `TestSignalKindShapeIntentional` stays green; the count is NOT changed
+  to 5).
+
+**Pitfalls:**
+- **Mission Lock const firewall integrity:** the
+  `MissionLockAmendment-Rejected` ProposalKind is the highest-risk
+  addition. Two designs: (a) `ValidateBasic` rejects the message (the
+  proposal never enters the keeper; cleanest), or (b) the handler accepts
+  it, records it as Pending, auto-transitions to Failed with an event
+  (documents the rejection on-chain). **Recommendation: (a)** — reject
+  at `ValidateBasic` so the message never reaches the handler (the const
+  is the firewall; the ValidateBasic is the gate). This matches the
+  Mission-Lock-non-amendable design (the proposal is unproposable, not
+  propose-then-fail). Flag as a planner decision. **Confidence 0.80**.
+- **Veto semantics:** a single Veto must NOT block (anti-greed; vision
+  §19). The Veto option is Watcher-only and the tally rule is a Watcher
+  quorum (e.g., 6-of-9 Watchers casting Veto transitions the proposal to
+  Failed; a single Veto is recorded but does not fail the proposal). The
+  handler enforces this: a Veto is counted in `NoWithVeto`, but the
+  proposal fails only if `NoWithVeto >= WatcherVetoQuorum` (a param, NOT a
+  locked const — defer the exact value to a v0.5 planner decision; the
+  v0.2 Params struct was empty, v0.5 adds a `WatcherVetoQuorum` param
+  defaulting to 6 to match REQ-004's 6-of-9). **Confidence 0.75** — the
+  quorum value is a planner decision.
+- **Proposal lifecycle ordering:** a vote on a non-Active proposal MUST be
+  rejected (the voting-deadline check). A tally on an Active proposal
+  before the deadline MUST be rejected. The handler checks status +
+  deadline in order (authz → status → deadline → tally). Simtest covers
+  the vote-after-deadline and tally-before-deadline rejections.
+- **SignalKind 4-not-5:** the AUDIT P1-2 rationale (Freeholder is
+  eligibility, Guild is a council tier, Capital is the 4th signal) is
+  documented in v0.4 ARCHITECTURE.md + the regression-guard test. v0.5
+  does NOT change `SignalKindCount`; the 4-source shape stays. A v0.6+
+  governance vote could expand it, but that requires a locked-const
+  amendment (a `feat:` that the Mission Lock firewall does NOT block
+  because SignalKind is not a Mission-Lock const — it's a locked-const
+  but not the Mission-Lock const; the distinction is documented in v0.4).
+- **Coverage:** the council runtime is the cross-cutting P7; ≥80%
+  coverage on the new enum types + handlers.
+
+**Confidence-scored conclusions:**
+- A-571: `Proposal` + `ProposalKind` (4, including the rejected
+  MissionLockAmendment kind) + `ProposalStatus` (5) + `VoteOption` (4)
+  are ADDED to `x/council/types` (AUDIT §193 P1-1 promotion); locked-const
+  tests added. **0.85**
+- A-572: `MissionLockAmendment-Rejected` proposals are rejected at
+  `ValidateBasic` (the message never reaches the handler); the const
+  firewall + the ValidateBasic gate are the dual firewall. **0.80** —
+  planner to confirm reject-at-ValidateBasic vs propose-then-fail.
+- A-573: `SignalKind` stays at 4 (P1-2 defensible; v0.4 regression-guard
+  test stays green); 5-source expansion deferred to v0.6+ governance
+  vote. **0.95**
+- A-574: Veto is Watcher-only, quorum-based (default `WatcherVetoQuorum
+  = 6` matching REQ-004 6-of-9); a single Veto does NOT block (anti-greed).
+  **0.75** — the quorum param value is a planner decision.

+
+## v0.5 §3. Cross-Cutting Concerns
+
+### v0.5 §3.1 G-006 controlled exception (cosmos-sdk dep, D-055)
+
+`go.mod` gains `github.com/cosmos/cosmos-sdk` (+ transitive deps) as the
+runtime substrate. This is a GRILL-approved controlled exception to G-006
+(zero-dep go.mod). The exception is scoped:
+- **Runtime phases (P1..P7):** `keeper/`, `msg_server.go`, `module.go`,
+  `simtest/` import cosmos-sdk. The dep is load-bearing.
+- **P0 (pre-execution) + P8 (final):** stay dep-neutral where possible
+  (this RESEARCH.md, PERSONAS.md, the planner's PLAN — no Go code).
+- **`types/` packages:** stay dep-free where possible. The v0.3 `types/`
+  packages are pure stdlib (`encoding/json`); v0.5 ADDS `types.Msg*`
+  structs which MUST implement `sdk.Msg`, so the `types/` package gains a
+  cosmos-sdk import for the message types. **Pitfall:** this breaks the
+  v0.1-v0.4 property that `types/` is zero-dep. Mitigation: isolate the
+  `Msg*` types in a `types/msg_*.go` file set and accept the `types/`
+  package now imports cosmos-sdk (the dep is already in `go.mod` for the
+  runtime; the `types/` import is consistent, not a new dep tree). The
+  invariant tests (locked-const, lexicon) stay stdlib-only and green.
+- **Version pin:** cosmos-sdk v0.50.x (LTS, go 1.22-compatible) is the
+  target; ibc-go v8.x (for cosmos-sdk v0.50) for the IBC packet handler
+  interfaces. ibc-go v10 (IBC v2 / Eureka) is attractive but requires
+  cosmos-sdk v0.50+ and is newer; the v0.5 pin should be cosmos-sdk v0.50.x
+  + ibc-go v8.x for stability (the IBC v2 patterns are documented in
+  RESEARCH but the v0.5 impl can use the v8 stable interfaces; v10 is a
+  later upgrade). **Confidence 0.78** — the planner confirms the version
+  pin; a GRILL review of the version is part of the controlled-exception
+  ratification.
+
+### v0.5 §3.2 G-003 production firewall (still intact)
+
+The G-003 by-ID-string rule (no production cross-`x/<module>/types` struct
+imports) survives the runtime promotion, BUT the runtime adds a NEW
+cross-module surface: keeper-to-keeper calls. The ibc-go convention for
+this is the `expected_keepers.go` shim: a module's `types/expected_keepers.go`
+defines Go INTERFACES for the keepers it depends on (e.g.,
+`x/exit/types/expected_keepers.go` defines a `BridgeKeeper` interface with
+the methods `x/exit`'s handler calls; the `x/bridge` keeper satisfies it
+structurally). The handler depends on the INTERFACE, not the concrete
+keeper struct. This is NOT a struct import of `x/bridge/types`; it is an
+interface defined in `x/exit/types`. G-003's intent (no cross-module struct
+coupling, no import cycles) is preserved.
+
+Test-only cross-package imports (the G-003 test exemption, used by REQ-030)
+remain exempt: a simtest may import both `x/exit/keeper` and `x/bridge/keeper`
+to wire the expected-keeper shims in a test setup.
+
+### v0.5 §3.3 Lexicon firewall (still green, extended surface)
+
+The lexicon firewall (`lexicon_meta_test.go` scanning `x/**/*.go` +
+`lexicon_meta_docs_test.go` scanning docs) automatically covers the new
+`keeper/`, `msg_server.go`, `simtest/` files. The highest-risk v0.5
+additions:
+- `x/hub` custody message names: AVOID "deposit" (banned) — use
+  `MsgCustodyReceiveAsset` / `MsgCustodyReleaseAsset` (A-542).
+- `x/bond` matching: "match"/"fill"/"cancel" safe; "interest"/"yield"
+  banned.
+- `x/council` Veto: "veto" is safe (not in the banned list); "VoteOption"
+  safe.
+- The `Msg*` struct names are the lexicon surface (they appear in the Go
+  source the firewall scans). A per-module lexicon assertion test
+  (`TestLexiconNoBannedTermsIn<Module>Package`) is added to each new
+  `keeper/` package or extended in the existing `types/` test.
+
+### v0.5 §3.4 Simtest grade (not mainnet)
+
+D-054 ratifies: runtime = simtest-grade handlers, NOT mainnet. The simtest:
+- Uses the SDK in-memory store (`dbm` in-memory backend), NOT a real
+  CometBFT node.
+- Exercises each handler against an in-memory `sdk.Context` (constructed
+  via `sdk.NewContext(store, header, true, logger)` or the
+  `simtestutil` helpers).
+- Asserts state transitions + event emission + idempotency (replay
+  rejection).
+- Does NOT test: real IBC light clients, real relayers, real MPC, real
+  bearer hardware, real DEX venues, real Watcher attestations (all
+  stubbed).

+
+## v0.5 §4. Assumptions (logged with confidence scores)
+
+| ID | Assumption | Confidence | Rationale |
+|----|-----------|------------|-----------|
+| A-501 | Every v0.5 target module gains a `keeper/` subdir + `msg_server.go`; the `types/` package stays as the locked-contract layer (no struct field removal). | 0.92 | Cosmos SDK MsgServer convention; D-054 ratifies. |
+| A-502 | The v0.3 in-memory `Keeper` stub (in `types/types.go`) is retired or wrapped by the store-backed keeper; the `types/` public API is not broken. | 0.80 | SDK migration; the stub may stay as a test helper. |
+| A-503 | Simtest uses the SDK in-memory store; no live chain, no real IBC light clients (D-054). | 0.90 | D-054 explicit. |
+| A-504 | `go.mod` gains cosmos-sdk v0.50.x + ibc-go v8.x (GRILL-approved D-055); `types/` packages gain the sdk.Msg import for `Msg*` types. | 0.78 | D-055 controlled exception; version pin is a planner/GRILL decision. |
+| A-505 | Keeper-to-keeper cross-module calls use `expected_keepers.go` interface shims (ibc-go convention); G-003 by-ID-string rule preserved at the type level. | 0.85 | ibc-go standard pattern; breaks import cycles. |
+| A-511 | `x/bridge` IBC handlers implement `OnRecvPacket`/`OnAcknowledgementPacket`/`OnTimeoutPacket` on the v0.3 `BridgeRoute` + ICS-20 v1 payload; Solana via wormhole-adapter branch. | 0.82 | ibc-go + D-059. |
+| A-512 | IBC ack/timeout replay protection mirrors ibc-go (delete-on-ack, refund-on-timeout); simtest covers both. | 0.90 | ibc-go CVE-class pitfall; simtest must cover. |
+| A-521 | OY-QR is one-shot; `MsgConsumeOYQR` flips `consumed` before the transfer effect; replay rejected idempotently. | 0.88 | v0.3 `consumed` flag; one-shot QR analog (Bolt Card). |
+| A-522 | `BearerTransport` interface gains a store-backed impl (keeper as transport in simtest); no hardware/RF dep (D-054). | 0.85 | D-054. |
+| A-531 | Anchor credential lifecycle = Pending → Onboarded → Suspended → Revoked (reuses v0.2 PartnerStatus 4-state shape). | 0.82 | v0.2 shape reuse. |
+| A-532 | P3→P4 hub dependency broken by `expected_keepers.go` shim; hub runtime impl wired in P4. | 0.85 | ibc-go convention; D-056 ordering. |
+| A-533 | Revocation authz delegates to `x/watcher` expected-keeper shim (6-of-9 quorum); no `x/watcher/types` struct import (G-003 intact). | 0.88 | REQ-004 + G-003. |
+| A-541 | `CustodyKeyring` interface (`Sign`/`Derive`/`Status`) + `memKeyring` in-memory test impl; real MPC/HSM deferred (D-058). | 0.88 | D-058 explicit. |
+| A-542 | Custody message names AVOID "deposit" (banned); use `MsgCustodyReceiveAsset`/`MsgCustodyReleaseAsset`. | 0.85 | Lexicon firewall; v0.5 discovery. |
+| A-543 | Lending handler clamps coupon to [0, 800] bps at runtime (D-028/REQ-030 runtime echo); clamp event emitted for simtest. | 0.82 | D-028 + REQ-030. |
+| A-544 | Compliance-before-custody ordering enforced (withdrawal checks compliance before debit). | 0.85 | State-machine ordering pitfall. |
+| A-551 | Per-kind service message handlers (one `Msg*` per ServiceKind), NOT a generic dispatch. | 0.80 | Typed dispatch. |
+| A-552 | `window-id` grant checked on EVERY service operation, not just registration (revoked Window invalidates ops). | 0.82 | Window lifecycle pitfall. |
+| A-561 | CLOB matching with price-time priority (FCFS at same price, REQ-007); per-tx matching in simtest (dYdX-v4-shaped). | 0.82 | D-057 + REQ-007. |
+| A-562 | Per-match coupon clamp to [0, 800] bps via v0.3 `Clamp`; a match above 800 is REJECTED (fails closed), not clamped-with-refund. | 0.70 | D-057 says "clamp"; runtime interpretation is reject. Planner to confirm. |
+| A-563 | 8%/0% consts referenced directly (not copied); REQ-030 cross-const test stays green. | 0.90 | D-028 + REQ-030. |
+| A-564 | No AMM in v0.5 (D-057); CLOB is the only matching engine. | 0.95 | D-057 explicit. |
+| A-571 | `Proposal` + `ProposalKind` (4, incl. rejected MissionLockAmendment) + `ProposalStatus` (5) + `VoteOption` (4) ADDED to `x/council/types` (AUDIT §193 P1-1). | 0.85 | D-060 + AUDIT P1-1. |
+| A-572 | `MissionLockAmendment-Rejected` proposals rejected at `ValidateBasic` (never reach handler); const firewall + ValidateBasic gate are dual firewall. | 0.80 | Mission-Lock non-amendable; planner to confirm reject-at-ValidateBasic. |
+| A-573 | `SignalKind` stays at 4 (P1-2 defensible; v0.4 regression-guard test stays green); 5-source expansion deferred to v0.6+. | 0.95 | D-060 + v0.4 AUDIT rationale. |
+| A-574 | Veto is Watcher-only, quorum-based (default `WatcherVetoQuorum = 6` per REQ-004 6-of-9); single Veto does NOT block (anti-greed). | 0.75 | Vision §19 anti-greed + REQ-004; quorum value is a planner decision. |

+|---|---|---|---|
+| x/bridge/types | 100.0% | ✓ | PASS |
+| x/exit/types | 100.0% | ✓ | PASS |
+| x/bearers/types | 100.0% | ✓ | PASS |

+| x/services/types | 100.0% | ✓ | PASS |
+| x/bond/types | 95.1% | ✓ | PASS |
+
+All packages exceed the ≥80% coverage requirement. The two sub-100% packages (hub 93.3%, bond 95.1%) have gaps only in defensive genesis error-branches (e.g., `validateComplianceServices` 87.5%, `Clamp`/`ClampLendingCoupon` 80% — the upper-bound and floor branches each exercised by ≥1 test but not every permutation). No must-have is uncovered; G-012 boundary cases (`currentBps==cap`, `currentBps>cap`, underflow guard) are all explicitly tested (`TestClampGrowthCurrentAtCapReturnsZero`, `TestClampGrowthCurrentAboveCapReturnsZero`, `TestClampGrowthInvariantPostGrowthLeCap`).
+
+### Per-axis verdicts
+
+#### 1. Correctness (backend-engineer) — PASS (0.92)
+
+Locked-const invariants all enforced and tested:
+- `BridgeStatusCount = 4` (x/bridge/types/types.go:18) — `AllBridgeStatuses()` returns 4 in REQ-015 order. ✓
+- `ExitStatusCount = 5` (x/exit/types/types.go:18) — `AllExitStatuses()` returns 5 in vision §7 order. ✓
+- `HubServiceCount = 3` (x/hub/types/types.go:42) — `AllHubServices()` returns 3 (Custody/LendingPrimitive/Compliance). ✓
+- `ServiceKindCount = 4` (x/services/types/types.go:37) — locked count asserted. ✓
+- `OrderSideCount = 2` (x/bond/types/types.go:171) — Buy/Sell. ✓
+- `OrderStatusCount = 3` (x/bond/types/types.go:174) — Open/Filled/Cancelled. ✓
+- `PartnerTierCount = 4` (x/partner/types/types.go:18) — regression intact. ✓
+- `BondStatusCount = 5` (x/bond/types/types.go:31) — regression intact. ✓
+- `CouponCapBps = 800` / `CouponFloorBps = 0` (x/bond/types/types.go:21,26) — D-028 LOCKED, regression firewall in types_test.go asserts both values. ✓
+
+**G-012 (ClampGrowth underflow guard) — CORRECT.** The guard at x/bond/types/types.go:239 (`if currentBps >= CouponCapBps { return 0 }`) runs BEFORE the `CouponCapBps - currentBps` subtraction (line 243), so the uint32 underflow path is unreachable. Five boundary/invariant tests cover: currentBps==0 (full room), currentBps==cap (return 0), currentBps>cap (return 0, NOT wrapped huge), growth>room (clamp to room), growth<room (unchanged), and a meta-assert `current + ClampGrowth(current, growth) <= max(current, cap)` across a fuzz table.
+
+The hub `LendingCouponCapBps`/`LendingCouponFloorBps` LOCAL consts (A-304) mirror x/bond's LOCKED values (800/0) without importing x/bond (G-003 preserved). Genesis-side clamp enforcement present in both `validateLendingPrimitives` (hub) and `ValidateBonds`/`ValidateGrowthBonds` (bond).
+
+#### 2. Testing (backend-engineer) — PASS (0.90)
+
+All new packages ≥93.3% (above 80% threshold). Per-package lexicon assertions present in every new package's types_test.go (TestLexiconNoBannedTermsIn<Pkg>Package + TestLexiconNoBannedTermsIn<Pkg>TestFile) — confirmed in x/bridge, x/exit, x/bearers, x/partner, x/hub, x/services, x/bond. G-012 boundary cases (currentBps==cap, currentBps>cap) explicitly tested. Locked-const regression tests present (Test<Const>LockedConst pattern) for every locked const enumerated above.
+
+#### 3. Security (security) — PASS (0.93)
+
+Both lexicon firewalls green:
+- x/ firewall (`lexicon_meta_test.go`, package `lexicon_meta`): `go test -run TestLexiconMeta ./` PASS.
+- docs/ firewall (`lexicon_meta_docs/lexicon_meta_docs_test.go`, package `lexicon_meta_docs`): `go test -run TestLexiconMeta ./lexicon_meta_docs/` PASS. Scans README.md + docs/**/*.md.
+
+Adversarial verification: confirmed `lexicon.FindBannedTerm` catches all 10 banned terms (bank, deposit, interest, yield, currency, dollar, euro, account, savings, depositor) via direct injection test. The docs firewall self-test table (G-009 for docs), walk-coverage test (G-013), and self-test drift assertion (G-014) all present and passing — the firewall provably CATCHES banned-term regressions rather than silently scanning nothing.
+
+**G-003 (by-ID-string, no struct imports between x/*) — INTACT.** `grep -rn "oy/openyield/x/"` across all new package non-test .go files returns ZERO struct imports. The only cross-package import in a test file is `x/bearers/types/types_test.go` importing `x/processing/types` (a test-only import for a stub reference; G-003 governs production struct imports, not test imports). All cross-module references in production types use ID-string fields (issuer-stand-id, reach-id, holder-reach-id, custody-provider-id, anchor-id, bond-id, operator-partner-id, etc.) with explicit G-003 doc-comments.
+
+#### 4. Performance (backend-engineer) — PASS (0.95)
+
+`go.mod` UNCHANGED since v0.1.5 (`git diff v0.1.5..HEAD -- go.mod go.sum` is empty) — zero external deps preserved (G-006). The mkdocs build deps (mkdocs + mkdocs-material) are Python-only and documented as non-Go (mkdocs.yml header comment). Skeleton stubs use O(1) maps for registry lookups (x/partner Keeper); no N+1 patterns in the stub code. The genesis validators iterate slices once (O(n) per set) with map-backed uniqueness checks — appropriate for skeleton scale.
+
+#### 5. Maintainability (lead-developer) — PASS (0.91)
+
+**Pattern consistency:** All new modules follow the v0.1/v0.2 file structure (types.go + types_test.go, genesis.go where genesis validation exists). The Params/GenesisState/DefaultGenesisState/ValidateGenesis pattern is uniform across x/bridge, x/exit, x/bearers, x/partner, x/hub, x/services, x/bond. G-008 split (data-engineer's genesis.go schema helpers composed by ValidateGenesis in types.go) is present in x/bond and x/hub. The new modules use the same ModuleName/StoreKey/RouterKey/QuerierRoute const block and the same JSON/YAML struct-tag convention as v0.1/v0.2 modules.
+
+**Docs cross-reference (G-011):** `mkdocs.yml` nav lists ALL 26 pages (1 Home + 8 Nomads + 8 Freeholders + 7 Shared + 2 Reference = 26), matching the 26 .md files under docs/. `docs/reference/components.md` cross-references the new modules (10 mentions of x/* packages). All docs pages are lexicon-clean (firewall green).
+
+**.ciagent/oy/* updates:** PROJECT, ROADMAP, REQUIREMENTS, ARCHITECTURE, RESEARCH, PERSONAS, PLANS, GRILL all updated to reflect v0.3 scope (Bearers & Documentation, REQ-024..REQ-028, D-037..D-046, A-304..A-313, G-011..G-014).
+
+#### 6. Adversarial (adversarial) — PASS (0.88)
+
+Adversarial probes attempted and their outcomes:
+1. **Banned term slipped into docs** — the firewall self-test table (`TestLexiconMetaDocsSelfTestTable`, G-009 for docs) injects synthetic banned-term strings and asserts FindBannedTerm detects each; the walk-coverage test (`TestLexiconMetaDocsWalkCoverage`, G-013) injects a real .md fixture under docs/.lexicon_fixture/ and asserts the walk FINDS it. Catches the "silently scans nothing and reports green" failure mode. ✓
+2. **Locked-const regression** — every locked const has a `Test<Const>LockedConst` regression test asserting the exact value AND the All<Enum>() entry count/names. A regression (e.g., BridgeStatusCount→5) fails the test. ✓
+3. **Struct import breaks G-003** — no production .go file in the new packages imports another x/* package; verified by grep. ✓
+4. **ClampGrowth underflow** — the guard returns 0 BEFORE the subtraction; the underflow path is unreachable; tested with currentBps>cap (e.g., 801) asserting return 0 (NOT 4294967295). ✓
+5. **Hub A-304 drift from x/bond D-028** — the LOCAL consts are documented as cross-referenced (comment "also 800") and a regression test asserts LendingCouponCapBps==800. A future x/bond cap change without a matching hub change is flagged by the cross-doc comment (not a test — appropriate since they are LOCAL to hub). Note P2 below.
+
+### P0 fixes auto-applied
+
+**0.** No P0 (critical) issues found. The milestone ships clean.
+
+### P1+ flags (post-hoc review — do NOT block ship)
+
+**1.** [P2 nit, maintainability] x/hub `LendingCouponCapBps`/`LendingCouponFloorBps` (A-304) are LOCAL consts cross-documented to x/bond's D-028 consts (both 800/0) but there is no automated cross-check that they stay in lockstep. If a future mission-locked change to x/bond.CouponCapBps does not update the hub LOCAL const, the two packages silently drift. The cross-doc comment in types.go:46-50 flags this for human review, but a shared-const test (e.g., asserting `LendingCouponCapBps == x/bond.CouponCapBps` — though that would require a test-only import, acceptable per G-003 test exemption) would be more robust. Recommend post-hoc: add a cross-package const-equality test OR document the manual-sync requirement in ARCHITECTURE.md. Not a ship blocker — both are currently 800/0.
+
+**2.** [P2 nit, testing] x/hub coverage 93.3% and x/bond coverage 95.1% leave defensive error-branches in `ClampLendingCoupon` (80%), `Clamp` (80%), `validateComplianceServices` (87.5%), `ValidateGrowthBonds` (85.7%) partially exercised. All must-have paths are tested; the uncovered lines are error-return branches for malformed genesis inputs. Recommend post-hoc: add 2-3 negative-case genesis tests per package to close the gaps to 100%. Not a ship blocker (both above the 80% threshold).
+
+**3.** [P2 nit, docs] `docs/reference/architecture.md` has 0 cross-references to x/* packages (vs `docs/reference/components.md` which has 10). The architecture page is conceptual; the components page is the cross-ref hub. Acceptable as-is, but post-hoc adding 1-2 module cross-refs to architecture.md would improve discoverability. Not a ship blocker.
+
+### Overall verdict
+
+**SHIP.**
+
+All verification commands pass. All locked-const invariants enforced and tested. Both lexicon firewalls green (x/ and docs/). G-003 (by-ID-string, no struct imports) intact across all new packages. G-012 (ClampGrowth underflow guard) correctly implemented with explicit boundary tests. Zero external deps (go.mod unchanged). Coverage ≥93.3% on all new/extended packages (above 80% threshold). mkdocs.yml nav complete (26/26 pages, G-011). No P0 issues. Three P2 nits flagged for post-hoc review (none blocking).
+
+**P0 fixes auto-applied: 0**

+# Review: OpenYield (oy) — v0.4 (Refinement — NFR) Final Phase
+
+> **Reviewer**: CIAgent multi-persona code review (lead-developer + backend-engineer lenses)
+> **Date**: 2026-08-17
+> **Target**: All v0.4 milestone commits (main..oy/milestone/v0.4-refinement) across P1..P3
+> **Milestone**: v0.4 — Refinement (NFR)
+> **Autonomy**: full
+
+## Scope Reviewed
+
+The v0.4 milestone ships 4 REQs across 3 execution phases (P1..P3) + phase 0 (pre-execution). 20 commits, 15 files changed (+764 / -157). The review covers the execution-phase deliverables:
+
+- **P1** (v0.3.1): REQ-029 lexicon shared helper, REQ-030 cross-const test
+- **P2** (v0.3.2): REQ-031 lifecycle divergence docs + regression guard
+- **P3** (v0.3.3): REQ-032 docs build CI
+
+## Adversarial Probes
+
+1. **Does the shared helper actually dedupe?** Probe: `grep -rn 'open a.*here\|make a.*now\|compounding.*rate' lexicon_meta_test.go lexicon_meta_docs/` — returns ZERO matches (the old duplicated table is gone; both meta-tests now call `lexicon.SyntheticBannedStrings()`). Verified at `lexicon_meta_test.go:93` and `lexicon_meta_docs/lexicon_meta_docs_test.go:155` (both consume the helper). ✓
+
+2. **Does the cross-const test fail closed on drift?** Probe: the test imports `bondtypes "github.com/oy/openyield/x/bond/types"` in `x/hub/types/cross_const_test.go:28` and asserts `LendingCouponCapBps != bondtypes.CouponCapBps` would fail the test. The absolute-value test `TestConstsAreMissionLocked800And0` (G-015) catches paired drift (both consts → 900). Both paths verified by reading the test. ✓
+
+3. **Does the regression guard lock the 4-signal shape?** Probe: `TestSignalKindShapeIntentional` at `x/council/types/types_test.go` asserts `SignalKindCount == 4` with a `t.Fatalf` (not `t.Errorf`) and checks `AllSignalKinds()` returns `[SignalStash, SignalStanding, SignalVouch, SignalCapital]` in order. The doc comment includes the AUDIT §193 P1-2 rationale. Changing `SignalKindCount` to 5 fails this test AND `TestSignalKindCountLockedConst`. ✓
+
+4. **Does the CI workflow YAML parse and enforce G-016?** Probe: `python3 -c "import yaml; doc=yaml.safe_load(open('.gitea/workflows/docs-build.yml')); assert doc['jobs']['docs-build']['needs'] == 'go-test'"` — passes. The `needs: go-test` line is present at `.gitea/workflows/docs-build.yml` in the `docs-build` job. ✓
+
+5. **Is `go.mod` really unchanged across the whole milestone?** Probe: `git diff main..HEAD -- go.mod` — empty. The CI workflow's Python deps are in a separate job; the lexicon helper adds no Go deps; the cross-const test adds no Go deps (test-only import of an internal package). G-006 intact. ✓
+
+6. **NFR purity gate — zero `feat:` commit SUBJECTS?** Probe: `git log --format="%s" main..HEAD | grep -E "^feat:"` — exit 1 (no matches). All 20 subjects are `docs(`, `refactor(`, `test(`, `chore(`, `verify(`, `decision(`, `checkpoint(`, or `Merge`. NOTE: `git log --grep "^feat:"` matches commit BODIES too (the v0.4 verify commits mention "feat:" in prose like "zero feat: commits in P2"); the correct gate uses subject-only check via `--format="%s"`. This is a documented refinement for the audit. ✓
+
+7. **Does G-003 hold — no production cross-module struct imports added?** Probe: `grep -rn "x/bond/types" x/hub/types/ --include="*.go" | grep -v "_test.go"` — zero matches. The only import of `x/bond/types` in `x/hub/types/` is in `cross_const_test.go` (a `_test.go` file, G-003 test-exempt). Production firewall intact. ✓
+
+## P0 fixes auto-applied
+
+**0.** No P0 (critical) issues found. The milestone ships clean.
+
+## P1+ flags (post-hoc review — do NOT block ship)
+
+**1.** [P2 nit, maintainability] The `mkdocs build` local run produced 2 warnings about README.md links (`docs/index.md` links to `../README.md`, `docs/shared/vision.md` links to `../../README.md`). These are pre-existing v0.3 docs links (not introduced by v0.4); the warnings are non-blocking (mkdocs builds successfully). Recommend post-hoc: either configure `mkdocs.yml` to include README.md in the nav, or fix the relative links. Not a v0.4 ship blocker (the docs site builds; v0.4's REQ-032 is the CI workflow, not the docs content).
+
+**2.** [P2 nit, CI] The `docs-build.yml` workflow uses `actions/upload-artifact@v4` with `retention-days: 14`. Gitea Actions may have a different artifact retention default; the explicit `retention-days: 14` is defensive. If Gitea Actions does not support v4 of the upload-artifact action, the workflow would fail at the upload step (the `mkdocs build` itself would have succeeded). Recommend post-hoc: verify Gitea Actions supports `actions/upload-artifact@v4`; if not, downgrade to v3 or use the Gitea-native artifact upload. Not a ship blocker (the build itself is the higher-priority check; the artifact upload is a bonus).
+
+**3.** [P2 nit, audit-gate precision] The NFR purity gate (`git log --grep "^feat:"`) over-matches commit bodies. The correct gate is subject-only (`git log --format="%s" | grep -E "^feat:"`). The P4 audit uses the subject-only check. Recommend post-hoc: document the subject-only gate in the next milestone's PLAN so future audits do not over-count. Not a ship blocker (the subject-only gate is green).
+
+## Overall verdict
+
+**SHIP.**
+
+All four REQs (REQ-029..REQ-032) delivered. The three real v0.3 forward-references (G-014 lexicon drift, A-304 const drift, AUDIT §193 council divergence) are closed; the D-046 docs-CI forward-reference is landed. `go test ./...` green across all 26 packages. `go.mod` unchanged (G-006). G-003 production firewall intact. NFR purity gate GREEN (zero `feat:` commit subjects). No P0 issues. Three P2 nits flagged for post-hoc review (none blocking).
+
+**P0 fixes auto-applied: 0**
+**P1+ findings: 0 P1, 3 P2 (all nits, post-hoc, non-blocking)**
+**Confidence in overall verdict: 0.90**

+//	  - Guild is a COUNCIL TIER (one of the three councils is the Guild

+//     OnboardAnchor (Pending → Onboarded). The handler asserts the
+//     custody-provider-id on the AnchorCredential references a live Hub
+//     custody service BEFORE transitioning to Onboarded. This is the
