+## 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 |
+| P1 | a780884 | v0.2.1 | complete | [REQ-028] | [REQ-027] | PASS |
+| P2 | d09c613 | v0.2.2 | complete | [] (nomads docs) | [REQ-027] | PASS |
+| P3 | 2ef3f2e | v0.2.3 | complete | [REQ-027] | [] | PASS |

+| P5 | c1aa274 | v0.2.5 | complete | [REQ-024, REQ-025, REQ-026] | [] | 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". ✓
+
+**Reconstruction test verdict: PASS** (6/6 phase blocks well-formed; 6/6 tags present; 6/6 REQ-coverage sets match; CHECKPOINT current).
+
+### File Discipline — **PASS** (after fix)
+
+`.ciagent/oy/` contains: PROJECT.md, ROADMAP.md, REQUIREMENTS.md, ARCHITECTURE.md, RESEARCH.md, PERSONAS.md, PLANS.md, GRILL.md, REVIEW.md, AUDIT.md. Plus historical P1_SHIP_VERIFICATION.md..P4_SHIP_VERIFICATION.md (v0.2 audit artifacts; not orphan — referenced by v0.2 AUDIT.md).

+
+**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).
+
+### Branch Hygiene — **PASS**
+
+- `git branch -a` lists: `main`, `oy/milestone/v0.3-bearers-docs`, `oy/phase/06-final-review-ship` (current), `remotes/origin/main`, `remotes/origin/oy/milestone/v0.3-bearers-docs`.

+- Multi-project `project: oy` field present in every `---ci---` block. ✓
+- No malformed blocks, no missing closing tags, no orphan phase markers.
+
+**Commit discipline verdict: PASS.**
+
+### Build/Test Sanity — **PASS**
+
+- `go build ./...` → GREEN (exit 0). ✓
+- `go test ./...` → 26 packages GREEN, 4 packages `[no test files]` (identity/processing/rootpool/vault — pre-existing v0.1 layout), zero FAIL. ✓

+# 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.

+v0.4.8 -> ABSENT (correct — final phase P8 creates it at ship)
+```
+All 8 tags pushed to `origin` (verified by `git ls-remote --tags origin`). The milestone release tag `v0.4.8` is NOT yet present — correctly deferred to the P8 ship step (P8-03-02).
+
+**REQ coverage vs. expected (P1: REQ-033; P2: REQ-034; P3: REQ-035; P4: REQ-036; P5: REQ-037; P6: REQ-038; P7: REQ-039): exact match on all 7 execution phases.** REQ-033..REQ-039 (the v0.5 requirement set per REQUIREMENTS.md §"v0.5 Milestone Requirements") are all covered; no REQ is double-counted, no REQ is missing.
+
+**CHECKPOINT.json** reflects: `phase: 1`, `stage: complete`, `milestone: v0.5`, `tag_base: v0.4.x`, `milestone_type: feature`, `phase_role: execution`, `project: oy`, `phase_release_tag: v0.4.1`, `release_id: 754`, `requirements_covered: [REQ-033]`. Valid JSON. NOTE: `phase: 1` reflects the last checkpoint-written execution phase (the checkpoint was last advanced at the P1 ship); P2..P7 did not write intermediate checkpoints (they used the `Merge phase/NN` squash pattern instead of `checkpoint(pN)` advance commits, except P0 and P1). This is a minor checkpoint-cadence deviation (P2..P7 checkpoint writes skipped), not a reconstruction blocker — the phase-ship `---ci---` blocks carry the authoritative phase/status/REQ state. The P8 ship step will advance the checkpoint to `phase: 8, stage: ship` (per P8-03-02).
+
+**Reconstruction test verdict: PASS.** The git log + `---ci---` blocks + tags fully reconstruct the v0.5 phase progression, REQ coverage, and milestone state. A reader can reconstruct the entire v0.5 milestone from commit messages alone.
+
+### 1.2 Commit structure observation (not a reconstruction failure)
+
+The 8 `Merge phase/NN into milestone/v0.5-bearers-runtime ...` commits are **single-parent commits**, not true 2-parent merges (`git cat-file -p` shows one `parent` line each; `c97e18f^2` is undefined). The phase work was committed directly onto the milestone branch as squash commits labeled "Merge phase/NN". This diverges from the plan's documented branch model (PLANS.md says phases ship on separate `phase/NN-*` branches then merge), but the `---ci---` blocks, tags, and REQ coverage are all correct and reconstructable. See §4 (commit discipline) and §8 (critical issues) for the feature-purity-gate consequence.

+
+## 2. `.ciagent` File Discipline — **PASS** (with one discipline deviation: ROADMAP v0.5 section absent — see §8)
+
+**All 9 canonical files present in `.ciagent/oy/`:**

+Plus historical artifacts: `P1_SHIP_VERIFICATION.md`..`P4_SHIP_VERIFICATION.md` (v0.2 phase-ship records; referenced by the v0.2 AUDIT.md; not orphan).
+
+**config.json — valid JSON, all required settings correct:**
+
+| Setting | Required | Actual | Verdict |
+|---|---|---|---|
+| `milestone_type` | `feature` | `feature` ✓ | PASS |
+| `tag_base` | `v0.4.x` | `v0.4.x` ✓ | PASS |
+| `ship.per_phase` | `true` | `true` ✓ | PASS |

+| `projects[]` length | >0 (multi-project) | 1 (`oy`) ✓ | PASS |
+| `milestone` | `v0.5` | `v0.5` ✓ | PASS |
+
+**Per-file v0.5 section presence:**
+- PLANS.md: v0.5 plan present (`# Plans: OpenYield (oy) — v0.5 (Bearers Runtime)` at line 1050; 8 phases P1..P7 + P8; task-count summary 36 tasks across 8 phases) ✓
+- GRILL.md: v0.5 grill present (G-017..G-024; 5 decision ratifications D-055, D-062, D-063, D-064, D-065; 8 binding fixes) ✓
+- REVIEW.md: v0.5 review present (PASS-WITH-FIXES → SHIP; 8 GRILL fixes landed; 0 P0; 5 P1+/P2 flagged) ✓
+- REQUIREMENTS.md: v0.5 table present (REQ-033..REQ-039, all class `feat`, status `pending` — correct per the brief: "will be marked Complete at milestone ship; for now they are the v0.5 requirements") ✓
+- ROADMAP.md: **NO v0.5 milestone section** (✗ — see §8 Critical-2). Prior milestones (v0.2, v0.3, v0.4) all had their sections added during P0 planning; v0.5 omitted this. The P8-03-01 ship task is responsible for adding it at ship, but the in-progress status should have been present during the milestone.
+
+**No stale `.ciagent/` files** — all referenced files exist. No orphan files detected.
+
+**File discipline verdict: PASS** (with one deviation documented in §8: ROADMAP.md v0.5 section absent — the ship step P8-03-01 must add it; the auditor is constrained from modifying ROADMAP.md per run constraints).

+
+## 3. Branch Hygiene — **PASS**
+
+| Check | Result | Verdict |
+|---|---|---|
+| `main` exists | at v0.4 milestone release (pre-v0.5) ✓ | PASS |
+| `main` is at v0.4 (pre-v0.5) | merge-base(main, milestone/v0.5) == main ✓ | PASS |
+| `milestone/v0.5-bearers-runtime` exists | local + `remotes/origin/milestone/v0.5-bearers-runtime` ✓ | PASS |
+| `milestone/v0.5-bearers-runtime` contains all P0-P7 work | 8 phase-ship commits P0-P7 + P8 verify ✓ | PASS |
+| `phase/08-final-review-ship` exists (current) | checked out, HEAD == `5d9ac3c` (verify(P8)) ✓ | PASS |
+| NO leftover execution phase branches | `git branch` lists only `main`, `milestone/v0.5-bearers-runtime`, `phase/08-final-review-ship` ✓ | PASS |
+
+`git branch` returns exactly three local branches: `main`, `milestone/v0.5-bearers-runtime`, `phase/08-final-review-ship` (current). The execution phase branches `phase/01-exit-bridge-runtime`..`phase/07-council-governance-runtime` are NOT present locally — consistent with the single-parent squash model (§1.2): phase work was committed directly to the milestone branch, so there were no separate phase branches to delete. Only the final-phase branch `phase/08-final-review-ship` remains (the active phase). The P8 ship step (P8-03-02) will delete it post-merge.
+
+**Branch hygiene verdict: PASS.**
+
+---
+
+## 4. Commit Discipline — **PASS** (with one deviation: feature-purity-gate subject convention — see §8 Critical-1)
+
+**`---ci---` block discipline:**
+- All 10 v0.5-scope commits (P0..P7 ship + P0/P1 checkpoint + P8 verify) carry `---ci---` blocks ✓
+- `project: oy` present in every block (multi-project discipline) ✓
+- `milestone: v0.5` present in every block ✓
+- `phase: N` correct integer (0..8) ✓
+- `status` field present and correct (`complete` on ships, `verify` on P8) ✓
+- `requirements.covered` present and correct on all phase-ship commits ✓
+- No malformed blocks, no missing closing `---/ci---` tags ✓
+
+**Conventional commit subjects:**
+- P0..P7 ship commits: `Merge phase/NN into milestone/v0.5-bearers-runtime ...` (conventional-ish; uses the `Merge` prefix) ✓
+- Checkpoint commits: `checkpoint(p0): ...`, `checkpoint(p1): ...` (conventional) ✓
+- P8 verify commit: `verify(P8): v0.5 final code review ...` (conventional `verify` prefix) ✓
+- No `docs(PNN):` / `feat:` / `refactor:` / `chore:` subjects in the v0.5 range on the first-parent line (the phase work was squashed into the `Merge phase/NN` commits rather than committed as `feat(PNN): ...`)
+
+**Feature purity gate (v0.5 is a FEATURE milestone — requires ≥1 `feat:` phase):**
+- **Substance gate: PASS.** v0.5 ships executable runtime behavior (8 modules promoted to live keeper MsgServer handlers + simtest; the cosmos-sdk v0.50.8 + ibc-go v8.2.1 dep D-055/D-062; CLOB matching D-057; CustodyKeyring D-058; Proposal/VoteOption enums D-060). This is unambiguously feature-class work, not NFR/refactor. The v0.3 `types/` contracts are NOT amended (runtime adds behavior on top — no breaking schema changes). The v0.5 P7 enums (`ProposalKindCount=4` / `ProposalStatusCount=5` / `VoteOptionCount=4`) are ADDITIVE (new types), not amendments to existing locked consts.
+- **Subject convention gate: DEVIATION.** `git log v0.3.4..HEAD --format="%s" | grep -E "^feat:"` returns ZERO matches. The phase work is committed under `Merge phase/NN` subjects (single-parent squash commits), not `feat(PNN): ...` subjects. The plan (PLANS.md Milestone Summary) says "all execution phases P1..P7 are `feat`" — the subject convention diverges from this. See §8 Critical-1 for the full analysis and disposition.
+- **No breaking schema changes: PASS.** Verified by reading the v0.3 `types/` files — the v0.5 runtime adds `keeper/`, `types/msg_*.go`, `types/expected_keepers.go`, `module.go` on top of the unchanged v0.3 `types/types.go` contracts. The locked-const firewall is intact (§6).
+
+**G-003 production firewall intact across all new v0.5 code:**
+- `grep -rn "openyield/x/" x/*/types/*.go` (non-test, excluding `expected_keepers.go`) → ZERO cross-module struct imports (GREP_EXIT=1) ✓
+- The keeper files (`x/*/keeper/*.go`, `x/*/module.go`) import their OWN module's `types` package (intra-module, expected and correct — G-003 governs CROSS-module struct imports in `types/` packages, not a keeper importing its own module's types)
+- Cross-module keeper coupling is via `expected_keepers.go` interface shims (8 files, one per module: BridgeKeeper, HubKeeper, BreadKeeper, WatcherKeeper, StandKeeper, GuildKeeper, ComplianceKeeper, PartnerKeeper) — INTERFACES only, no struct imports ✓
+- The existing G-003 import-invariant test (`x/window/types/types_test.go:437` `TestG003NoCrossModuleStructImportsInProduction`) auto-covers the new v0.5 files and passes ✓
+
+**Commit discipline verdict: PASS** (substance + `---ci---` blocks + conventional subjects all green; the `feat:` subject-convention deviation is documented in §8 Critical-1 as a non-blocking documentation defect — the substance is feature work; history is tagged/pushed and cannot be rewritten).
+
+---
+
+## 5. Test + Coverage Discipline — **PASS**
+
+| Check | Command | Result | Verdict |
+|---|---|---|---|
+| Build | `go build ./...` | exit 0, GREEN | PASS |
+| Tests | `go test ./...` | exit 0, 34 packages `ok` (13 `[no test files]` — pre-existing v0.1 layout), zero FAIL | PASS |
+| Lexicon firewall (x/) | `go test -run TestLexiconMeta ./...` | GREEN (both firewalls: x/ + docs/) | PASS |
+| G-003 invariant | `go test -run TestG003NoCrossModuleStructImportsInProduction ./x/window/types/` | GREEN | PASS |
+| G-024 stdlib-only types tests | `grep -rln "cosmos-sdk\|sdk.Msg\|sdk.Context" x/*/types/*_test.go` | exit 1 (ZERO hits — invariant/lexicon tests remain stdlib-only) | PASS |
+
+**Coverage on all 8 keeper packages (≥80% required, D-033; verified by `go test -cover`):**
+
+| Package | Coverage | Verdict |
+|---|---|---|
+| `x/exit/keeper` | 85.0% | PASS |
+| `x/bridge/keeper` | 82.1% | PASS |
+| `x/bearers/keeper` | 91.2% | PASS |
+| `x/partner/keeper` | 87.6% | PASS |

+| `x/services/keeper` | 91.5% | PASS |
+| `x/bond/keeper` | 92.5% | PASS |
+| `x/council/keeper` | 90.3% | PASS |
+
+All 8 keeper packages exceed the ≥80% target. Floor = 82.1% (`x/bridge/keeper`); ceiling = 92.5% (`x/bond/keeper`). D-033 satisfied with margin. The simtest files (`msg_server_simtest_test.go` in each keeper) exercise the MVP/UX flows: bridge IBC recv/ack/timeout, bearers OY-QR one-shot consume, partner anchor credential lifecycle, hub custody release + lending clamp, services lifecycle, bond CLOB match, council proposal/vote/tally.
+
+**Test + coverage verdict: PASS.**

+
+## 6. Locked-Const Firewall — **PASS** (all v0.1..v0.5 consts verified unchanged in source)
+
+Verified by direct `grep` of every const listed in the audit brief against the source files:

+| `WatcherVetoQuorumDefault` (NEW v0.5, param-tunable NOT locked-const) | 6 | `x/council/types/types.go:60` | `= 6` (default; `Params.Validate` bounds [2,9] at lines 199-204 — G-020) ✓ | PASS |
+
+**All v0.1..v0.4 locked-consts unchanged.** The v0.5 additions are ADDITIVE only:
+- `AnchorCredentialStatusCount = 4` (new in `x/partner/types/anchor_credential.go` — a new enum for the Anchor credential lifecycle; does not amend `PartnerTierCount` or `PartnerStatusCount`)
+- `WatcherVetoQuorumDefault = 6` (new in `x/council/types/types.go` — a DEFAULT for the `Params.WatcherVetoQuorum` field, NOT a locked const; G-020 bounds [2,9] enforced in `Params.Validate`; param-tunable per D-065)
+- P7 council governance enums (`ProposalKindCount` / `ProposalStatusCount` / `VoteOptionCount`) — new types added per D-060 (AUDIT §193 P1-1 closure); additive, no existing enum amended.
+
+**Locked-const firewall verdict: PASS.** No v0.1..v0.4 locked-const was amended. The v0.5 additions are additive (feature purity gate substance: no breaking schema changes).
+
+---
+
+## 7. `go.mod` Discipline — **PASS** (G-006 controlled exception GRILL-ratified)
+
+| Check | Expected | Actual | Verdict |
+|---|---|---|---|
+| `go` directive | 1.22 (G-018, not bumped) | `go 1.22` (go.mod line 3) ✓ | PASS |
+| cosmos-sdk pin | v0.50.8 (D-062) | `github.com/cosmos/cosmos-sdk v0.50.8` (direct require) ✓ | PASS |
+| ibc-go pin | v8.2.1 (D-062) | `github.com/cosmos/ibc-go/v8 v8.2.1` (direct require) ✓ | PASS |
+| G-006 controlled exception | GRILL-ratified (D-055/D-062) | D-055 ratifies the cosmos-sdk + ibc-go dep as the G-006 controlled exception; D-062 pins the versions; GRILL §1 "Decision Ratifications" confirms both ✓ | PASS |
+| G-018 hard build gate | `go build ./...` exits 0 under go 1.22 | `go build ./...` exit 0 ✓ | PASS |
+| Only deps added in v0.5 | cosmos-sdk + ibc-go (D-055) | The direct `require` block adds `cosmossdk.io/store v1.1.0`, `cosmos-sdk v0.50.8`, `ibc-go/modules/capability v1.0.0`, `ibc-go/v8 v8.2.1` — all part of the cosmos-sdk v0.50.x + ibc-go v8.x transitive tree (D-062 pin). No OTHER deps added outside this exception ✓ | PASS |
+
+**`go.mod` discipline verdict: PASS.** The G-006 controlled exception (D-055/D-062) is the only dep addition in v0.5. The go directive remains 1.22 (G-018 hard gate green). The cosmos-sdk v0.50.8 + ibc-go v8.2.1 pins match D-062 exactly.
+
+---
+
+## 8. Critical Issues Found
+
+**Initial critical issue count: 2.** Both are in surfaces the auditor is constrained from modifying (ROADMAP.md / REQUIREMENTS.md per run constraints; commit history per no-rewrite + no-tag constraints). Neither is a code/source defect — `go build ./...` + `go test ./...` are green, all locked-consts intact, G-003/G-018/G-024 firewalls green. Both are documentation/commit-hygiene defects flagged for the P8 ship step to address.
+
+### Critical-1: Feature purity gate — zero `feat:` commit subjects in the v0.5 range
+
+- **Spec**: PLANS.md v0.5 Milestone Summary — "Type: Feature (all execution phases P1..P7 are `feat`; P8 is `final`)". The feature purity gate requires ≥1 `feat:` commit subject.
+- **Pre-fix state**: `git log v0.3.4..HEAD --format="%s" | grep -E "^feat:"` returns ZERO matches. The 7 execution-phase work units (P1..P7) are committed as single-parent squash commits with subjects `Merge phase/NN into milestone/v0.5-bearers-runtime (PN complete → v0.4.N)`. None use the `feat:` conventional prefix.
+- **Impact**: A reader auditing commit subjects alone would NOT see the `feat:` signal that distinguishes a feature milestone from an NFR milestone. The v0.4 NFR purity gate used the subject-only check (`git log --format="%s" | grep -E "^feat:"` → zero = GREEN for NFR); applying the same check to v0.5 yields zero, which is GREEN for an NFR but RED for a feature. The substance IS feature work (8 modules promoted to runtime MsgServer handlers + simtest; cosmos-sdk dep; CLOB matching; CustodyKeyring; governance enums) — the subject convention diverges from the substance.
+- **Root cause**: The phase work was squashed directly onto the milestone branch as `Merge phase/NN` commits (single-parent, not true 2-parent merges — verified by `git cat-file -p`) rather than committed on separate `phase/NN-*` branches with `feat(PNN): ...` subjects then merged.
+- **Disposition**: **DOCUMENTED, NOT FIXED in this phase.** The history is tagged (v0.4.0..v0.4.7) and pushed to `origin`; rewriting it would require force-pushing tagged history, which violates the run constraints ("Do NOT tag, merge, or modify CHECKPOINT.json" + the git safety protocol forbids force-pushing tagged history). The auditor is read-only on commit history. **The substance of the feature purity gate is satisfied** (the work is unambiguously feature-class; no breaking schema changes; v0.5 P7 enums additive; locked-const firewall intact). The subject-convention deviation is a non-blocking documentation/commit-hygiene defect. **Recommendation for the orchestrator/ship step**: (a) the P8-03-02 ship commit (`docs(milestone): complete v0.5`) should reference the feature-class substance in its body; (b) future feature milestones should use `feat(PNN): ...` subjects on phase branches before merging, per the PLANS.md convention.
+
+### Critical-2: ROADMAP.md has NO v0.5 milestone section
+
+- **Spec**: PLANS.md P8-03-01 — "Update ROADMAP.md: mark v0.5 milestone COMPLETE; add the tag-line note that v0.5 shipped on the `v0.4.x` patch line". Prior milestones (v0.2, v0.3, v0.4) all had their ROADMAP sections added during P0 planning (in-progress status), then marked COMPLETE at ship.
+- **Pre-fix state**: `grep -n "v0.5\|Bearers Runtime" ROADMAP.md` returns ONE match (line 88: a forward-reference note "v0.3 Bearers skeletons are deferred to v0.5+"). There is NO `## Milestone v0.5 — Bearers Runtime` section. The ROADMAP jumps from `## Milestone v0.4 — Refinement (COMPLETE)` directly to `## Phase 3 — The Bearers (Year 3) — v0.3 PARTIAL SKELETON` (the vision narrative). A reader of ROADMAP.md cannot see that v0.5 is in progress or what it ships.
+- **Impact**: A reader cannot reconstruct the v0.5 milestone's existence, phase plan, or tag-line from ROADMAP.md alone (the reconstruction test in §1 relies on the git log + PLANS.md, not ROADMAP.md). This is a file-discipline defect — every prior milestone added its ROADMAP section during planning.
+- **Root cause**: The v0.5 P0 planning stage did not append a ROADMAP.md v0.5 section (unlike v0.2/v0.3/v0.4 P0 stages). The P8-03-01 ship task is responsible for adding it at ship, but the in-progress status should have been present during the milestone.
+- **Disposition**: **DOCUMENTED, NOT FIXED in this phase.** The run constraints explicitly forbid the auditor from modifying ROADMAP.md ("Do NOT touch PROJECT.md, REQUIREMENTS.md, ROADMAP.md, RESEARCH.md, ARCHITECTURE.md, PERSONAS.md, GRILL.md, PLANS.md, REVIEW.md — only AUDIT.md + source fixes"). **The P8-03-01 ship step MUST add the v0.5 ROADMAP section** (header `## Milestone v0.5 — Bearers Runtime (COMPLETE; feature type; tags v0.4.x)` with P0..P8 checkbox list + tag-line note + component-mapping table mirroring the v0.3/v0.4 section format) and mark it COMPLETE at ship.
+
+**Post-fix verification**: N/A — neither critical issue is fixed in this phase (both are out-of-surface for the auditor). `go build ./...` + `go test ./...` re-confirmed GREEN after the AUDIT.md append (documentation-only change; no source touched). **Remaining critical issue count after this audit: 2** (both deferred to the P8 ship step, which owns ROADMAP.md/REQUIREMENTS.md updates and the ship commit).
+
+---
+
+## 9. P1+ Issues from REVIEW.md (acknowledged — 5 flagged for v0.6+)
+
+The v0.5 REVIEW.md (§4) flagged 5 P1+/P2 issues for post-hoc review. None block the v0.5 ship (all are mainnet-readiness concerns for v0.6+, consistent with D-054 simtest grade). The audit acknowledges and endorses these flags:
+
+| # | Severity | Issue | Disposition |
+|---|---|---|---|
+| 1 | P1 (security) | No proposal deposit/bond at v0.5 simtest grade — `MsgSubmitProposal` does not bond a deposit; a mainnet spammer could flood Pending proposals | Flag for v0.6+ (add deposit gate, standard `x/gov` pattern) — not a v0.5 blocker (simtest grade) |
+| 2 | P1 (adversarial) | CLOB per-tx matching is front-running-exposed at mainnet — no batch auction; tx-ordering advantage could sandwich | Flag for v0.6+ (evaluate batch auction / commit-reveal) — not a v0.5 blocker (simtest grade) |
+| 3 | P1 (maintainability) | Simtest does NOT exercise real IBC light-client verification — in-memory `sdk.Context` + stub keepers (G-022) | Flag for v0.6+ mainnet-readiness milestone — not a v0.5 blocker (D-054 simtest grade explicit) |
+| 4 | P2 (performance) | CLOB `restingBookForBond` is O(n) over all resting orders (loads `AllRestingOrders` then filters) | Flag for v0.6+ (prefix-key the book store by `BondID`) — not a v0.5 blocker (simtest depth) |
+| 5 | P2 (maintainability) | `emitMatchEventHook` package-level mutable var in `clob.go` — pragmatic split but a testability smell | Flag for v0.6+ (pass emitter as Keeper field / constructor injection) — not a v0.5 blocker (simtest is serial) |
+
+All 5 are post-hoc, non-blocking, and consistent with the D-054 simtest-grade scope. The audit confirms REVIEW.md's verdict: **PASS-WITH-FIXES → SHIP** (all 8 GRILL fixes G-017..G-024 landed with evidence; 0 P0; 5 P1+/P2 flagged).
+
+---
+
+## 10. Overall Audit Verdict
+
+### **PASS** (with 2 documentation/commit-hygiene issues deferred to the P8 ship step)
+
+The v0.5 (Bearers Runtime) milestone is **shippable**. The 2 critical issues (§8) are both in surfaces the auditor cannot modify (ROADMAP.md per run constraints; tagged/pushed commit history per no-rewrite constraints) and both are the P8 ship step's responsibility (P8-03-01 adds the ROADMAP v0.5 section; P8-03-02 creates the `v0.4.8` ship commit). Neither is a code/source defect — the build is green, tests are green, all locked-consts are intact, all firewalls (G-003/G-018/G-024/lexicon) are green.

+
+**Critical issues: 2 found → 0 fixed in this phase (both out-of-surface) → 2 deferred to P8 ship step.**
+- Critical-1 (feature purity gate `feat:` subject convention): DOCUMENTED — substance is feature-class; subject convention diverged; history tagged/pushed, cannot rewrite.
+- Critical-2 (ROADMAP.md v0.5 section absent): DOCUMENTED — P8-03-01 ship step must add it; auditor constrained from modifying ROADMAP.md.

+
+| Category | Finding | Severity | Disposition |
+|---|---|---|---|
+| Spoofing | No new auth surface added in v0.5 (runtime handlers use expected-keeper interface shims; no identity assertion logic); Anchor revocation authz via WatcherKeeper 6-of-9 quorum shim (REQ-004) | Low | Accept |
+| Tampering | Mission Lock const firewall intact (`MissionLockAmendable=false` in council + pact); D-064 adds `ValidateBasic` gate rejecting `MissionLockAmendment-Rejected` proposal kind (defence in depth — const + ValidateBasic + handler kind-switch); CLOB per-match REJECT above 800 bps (D-063 — fails closed, no usury violation); locked-const regression tests all green | Low (improved) | Accept |
+| Repudiation | All runtime handlers emit events after state mutation (state-machine ordering: ValidateBasic → keeper authz → state mutation → event emit); IBC in-flight records deleted on first ack (A-513 replay protection); OY-QR `consumed` flip is state-write-first (A-521) | Low | Accept |
+| Info Disclosure | OY-SAT surveillance-resistant invariant (`OYSATSurveillanceResistant=true` LOCKED); handler emits NO geolocation fields (negative test); no secrets in code; lexicon firewall green on all new runtime files | Low | Accept |
+| Denial of Service | No proposal deposit/bond at simtest grade (REVIEW P1-1 — flagged for v0.6+ mainnet); CLOB per-tx matching front-running-exposed (REVIEW P1-2 — flagged for v0.6+); simtest grade does not model mempool ordering (D-054) | Low (simtest grade; mainnet DoS surface is v0.6+) | Accept |
+| Elevation of Privilege | G-003 production firewall intact (zero cross-module struct imports; expected_keepers.go interfaces); WatcherVetoQuorum bounds [2,9] (G-020 — no single-Veto-block, no unsatisfiable quorum); MissionLockAmendment unproposable at ValidateBasic (D-064) | Low | Accept |
+
+No threat exceeds the low/accept threshold. No escalations. The v0.5 runtime promotion introduces simtest-grade message handlers with no mainnet attack surface (D-054); all security-relevant invariants (Mission Lock, Bond Clamp, G-003 import firewall, surveillance-resistance, IBC replay/timeout) are compile-time consts + tested firewalls + simtest-verified handlers.

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.

The v0.3 OYSATLink (surveillance-resistant=true locked) and OYQRCode (one-shot consumed flag) become the handler state objects. 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.

 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.

-    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 |
+|-------|----------|------|

+| P7 (council governance runtime) | backend-engineer + cosmos-engineer + security-engineer | REQ-039: Proposal/VoteOption enums (AUDIT §193 P1-1); Voice lifecycle handlers; MissionLockAmendment-Rejected rejected at ValidateBasic (A-572); Watcher Veto quorum (A-574, default 6); SignalKind stays 4 |
+| P8 (final review/audit/ship) | lead-developer + ci-security-auditor (activated) | feature purity gate audit; locked-const firewall verification; G-003 + G-006 (D-055 exception) verification; milestone ship |
 
-### 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
-v0.3 — Bearers & Documentation (active milestone; feature type; tags run on the v0.2.x patch line)
+v0.6 — Nomad Web UI (in progress; feature type; tags run on the v0.5.x patch line)
+
+### v0.6 Scope (Nomad Web UI MVP — generated test data, no real chain)
+
+v0.6 is the project's first UI milestone. It delivers a working prototype Web
+UI where a person can sign up to be a Nomad (create a Reach + open a Stash)
+and exercise basic functionality around the (Reach, Stash) components, plus
+Window authorization, Standing progress, and Bloom accrual views. All data is
+generated as test fixtures — there is no real blockchain interaction, no live
+chain launch, no real bearer transports (D-020 continues to govern network
+deployment). The UI is a greenfield Go `html/template` + HTMX layer served by a
+Go mock HTTP server that instantiates the real `x/*/types` structs (Reach,
+Stash, Window, FreeholderSignals, BloomRecord) populated from in-memory
+fixtures. No keeper, no Cosmos runtime, no `app.go` (none exists in the repo).
+
+This milestone is the prerequisite for real-world MVP testing: it makes the
+Nomad path visible and exercisable in a browser. Wiring the UI to a real `oyd`
+daemon (once one exists) is deferred to v0.7+ (no `app.go`, `cmd/`, or `main.go`
+exists in the repo today).
+
+- **REQ-040** Nomad Reach signup Web UI — Go HTTP mock server (`web/`) + "Create a Reach" form + Reach list/detail; grounds the UI in `x/identity/types.Reach`. "Sign up" maps to "Create a Reach" (the word "account" is banned per REQ-012).
+- **REQ-041** Stash dashboard Web UI — balance in Grain + Bread-scale conversion (using `x/bread/types.BreadScaleAll()`) + 90-day maturity progress bar (`x/stash/types.StashActivity.IsMature`).
+- **REQ-042** Window authorization Web UI — form to open a Window (scope + duration + rate-limit), lifecycle view (Open→Active→Revoked/Expired via `x/window/types.Window.Activate/Revoke/Expire`), audit log.
+- **REQ-043** Standing + Freeholder signals progress Web UI — computed from mock `Rating`/`Vouch`/`Slash` records using the locked constants + `GetStandingBucket`/`ComputeDiversityBonus`/`GetVoucherWeight`; 4-signal progress (`FreeholderSignals.IsFreeholderEligible`).
+- **REQ-044** Bloom accrual Web UI — per-Stash `BloomRecord` view (`AccruedGrain`, `RateBasisPoints`), computed from mock data; shows the 4.5% target rate.
+- **REQ-045** Extend REQ-012 lexicon firewall to scan `web/templates/**` + `web/static/**` (new `lexicon_meta_web_test.go`). Firewall-first: lands in P1 before content.
+
+### Milestone Type
+Feature (all execution phases are `feat` except REQ-045 which is `test`). Phase 0 → `v0.5.0`; execution phases `v0.5.1..v0.5.5`; final phase patch `v0.5.6` IS the v0.6 milestone release. No separate minor tag. The final-phase audit enforces the feature purity gate (no breaking schema changes; G-003 production firewall intact; G-006 go.mod unchanged unless a runtime dep is GRILL-approved — HTMX is a vendored static asset, not a Go dep).
+
+### Out of Scope (v0.6)
+- Real blockchain interaction / mainnet / IBC / real bearer transports (D-020 continues)
+- A real `oyd` daemon / `app.go` / `cmd/oyd` (no chain runtime exists; deferred to v0.7+)
+- Real Anchors onboarding / Hub API B2B / real custody (simtest/mock only)
+- Authentication / sessions / real key management (mock; a Reach is created by form submission, stored in-memory)
+- Persistence (mock store is in-memory; resets on restart)
+- i18n / multi-language UI
+- Real Standing oracle / real Bloom accrual engine (computed from fixtures using locked constants)
+- The 5 P1+ mainnet-readiness items deferred from v0.5 (governance spam deposit, CLOB front-running, real IBC simtest, CLOB perf, emitMatchEventHook testability) — those are v0.7+ mainnet-readiness, not UI work
+
+### Prior Milestones
+- v0.1 — OpenYield Foundation Init (COMPLETE; pre-MVP foundation skeleton; released as v0.0.9)
+- v0.2 — The Mesh (COMPLETE; skeleton + tests; released as v0.1.5)
+- v0.3 — Bearers & Documentation (COMPLETE; feature; released as v0.2.6)
+- v0.4 — Refinement (COMPLETE; NFR; released as v0.3.4)
+- v0.5 — Bearers Runtime (COMPLETE; feature; released as v0.4.8)
+
+## Prior Milestone
+v0.5 — Bearers Runtime (complete; feature type; tags ran 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.

+
+| 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). No separate minor tag. | The candidate work set (REQ-029..REQ-032) is entirely refactor/test/quality/chore. 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. Each phase independently shippable; P1 lands the firewall durability fixes first (highest-severity regression risk). | P1 bundles the two lexicon/const firewall fixes (same territory); P2 is documentation+test; P3 is CI config. Vertical slices. | 0.80 | [different wave ordering] |
+| D-053 | **No IDEATE stage in v0.4** (no `--ideate` flag this run). The NFR scope was pre-seeded from v0.3 forward-references and ratified at CLARIFY. If `--ideate` is passed on a later v0.4 run, the D-001 refinement-only filter applies. | run.md §IDEATE is conditional on `--ideate`. This invocation has no `--ideate`. | 1.00 | [run IDEATE anyway] |

+## Clarification Decisions (Phase 0 v0.5 — CLARIFY, autonomy=full)
+
+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. No new L2 chains in v0.5. Solana IBC uses the wormhole-style bridge adapter (already stubbed in `x/bridge` per D-021). | The 5 L2 chains are the locked-const set (REQ-009). Adding new chains is a Year-4 concern. Solana IBC was a v0.1 deferred item (D-021) now promoted. | 0.82 | [add 3+ new L2 chains (Year 4); defer Solana IBC again (stalls)] |
+| D-060 | **Council governance shape (AUDIT §193 P1-1)**: add `Proposal` and `VoteOption` enum types to `x/council/types` (currently absent per AUDIT). `ProposalKind` enum = {Stand, Guild, Mesh, MissionLockAmendment-Rejected} (Mission Lock non-amendable → the enum value exists but the handler rejects it; documents the non-amendability in code). `VoteOption` enum = {Yes, No, Abstain, Veto} (Veto = Watcher-only, quorum rule). SignalKind stays at 4 sources (P1-2 defensible per AUDIT; expansion deferred to v0.6+ governance vote). Mission Lock const firewall (G-003) intact. | AUDIT P1-1 flagged the absence as a divergence. Adding the enums is `feat:` (deferred from v0.4 by D-001). P1-2 (SignalKind 4→5) is a locked-const change rejected by the audit rationale, so it stays at 4. | 0.82 | [add SignalKind 5th source (locked-const change, rejected); defer Proposal/VoteOption again (stalls)] |
+| D-061 | **No IDEATE stage in v0.5** (no `--ideate` flag this run). The feature scope was pre-seeded from PROJECT.md v0.4 out-of-scope + AUDIT §193 P1-1 + D-050 and ratified at CLARIFY. The D-001 refinement-only filter does NOT apply (v0.5 is a feature milestone, not NFR). | run.md §IDEATE is conditional on `--ideate`. This invocation has no `--ideate`. | 1.00 | [run IDEATE anyway] |
+
+## Clarification Decisions (Phase 0 v0.6 — CLARIFY, autonomy=full)
+
+Auto-decided defaults logged per clarify workflow Step 4 (full autonomy → accept defaults, log decisions). `--ideate` flag IS present this run; v0.6 is the project's first UI milestone. The D-001 refinement-only filter does NOT apply (v0.6 is a feature milestone). User-validated stack choices recorded via interactive questions: Go `html/template` + HTMX (frontend stack), Go mock API server (mock data layer), all 5 screens (Reach signup, Stash dashboard, Window authorization, Standing + Freeholder signals, Bloom accrual), new top-level `web/` dir (UI code location).
+
+| ID | Decision | Rationale | Confidence | Alternatives |
+|----|----------|-----------|------------|--------------|
+| D-066 | **Frontend stack = Go `html/template` + HTMX.** HTMX is a single vendored JS file served as a static asset — no node toolchain, no `package.json`, no build step. Go `html/template` is stdlib. **G-006 (zero-dep) is preserved** — this is the decisive factor vs. a React/Svelte SPA. Sufficient for Reach/Stash/Window/Standing/Bloom screens (progressive enhancement over server-rendered HTML). Weakest for rich dashboards, but adequate for an MVP prototype. | User-validated. Project has a strong zero-dep ethos (G-006); v0.5 took a controlled G-006 exception for cosmos-sdk only after GRILL ratification. A node toolchain + `package.json` would be a far larger exception for a UI MVP that can be served by stdlib + one vendored JS file. | 0.88 | [React/Vite SPA (adds node toolchain, breaks Go-only convention); SvelteKit (same tradeoff); pure static HTML/CSS/vanilla JS (most fragile)] |
+| D-067 | **Mock data layer = Go HTTP server in `web/` instantiating real `x/*/types` structs.** New top-level `web/` dir holds `main.go`, HTTP handlers, an in-memory mock store seeded from fixtures, and `static/` + `templates/`. The mock store imports `x/identity/types`, `x/stash/types`, `x/window/types`, `x/standing/types`, `x/bread/types`, `x/bloom/types` and populates them with test values. **No keeper, no Cosmos runtime, no `app.go`** (none exists in the repo). This grounds the UI in the actual locked data shapes (Reach, Stash, Window, FreeholderSignals, BloomRecord) — the UI does not exercise a chain but does exercise the real Go type definitions. | User-validated. The four modules the Nomad UI primarily surfaces (identity, stash, window, standing) are types-only skeletons with no keeper/MsgServer. A Go mock server reuses the type definitions as the source of truth, so the UI is grounded in the locked constants (GrainsPerBread=10000, MaturityThresholdDays=90, standing formula) rather than mirroring them in TS/JSON. | 0.85 | [frontend-only TS/JSON fixtures (UI would not exercise any Go code path); Go mock API + in-memory keepers (more code, premature)] |
+| D-068 | **UI code location = new top-level `web/` dir.** Clean separation from `x/` protocol modules; does not touch the `go.mod` module path; does not pretend to be a Cosmos module. `web/` contains `main.go` (or `cmd/oyd-ui/main.go`), handlers, mock store, fixtures, `static/`, `templates/`. | User-validated. The Mesh Experience component is ROADMAP Phase 2, not a v0.6 deliverable; coupling the UI to Cosmos module conventions (a new `x/meshexperience`) is premature. A top-level `web/` dir matches the project's existing convention of non-`x/` top-level dirs (`docs/`, `lexicon/`, `lexicon_meta_docs/`). | 0.90 | [new `x/meshexperience` Cosmos module (couples UI to Cosmos conventions prematurely); `cmd/oyd-ui` + `web/` split (more files, clearer build)] |
+| D-069 | **Lexicon firewall extension to `web/`.** REQ-012 currently scans `x/` + `docs/`. A new sibling meta-test `lexicon_meta_web_test.go` (package `lexicon_meta_web`) scans `web/templates/**/*.html` + `web/static/**/*.js` for the 10 banned terms, using the same `lexicon.FindBannedTerm` + word-boundary regex. Self-exclusion + fragment pattern preserved. **"Sign up" maps to "Create a Reach"** — the word "account" is banned (REQ-012). Firewall-first: lands in P1 before content (P2..P5) so UI strings are lexicon-clean by construction. | REQ-012 is `All` phases and UI strings are user-facing; the firewall must cover the UI to be durable. Extending the existing meta-test pattern (not modifying it) preserves v0.2/v0.3 coverage. Firewall-first (D-044 pattern) ensures UI content is lexicon-clean by construction, not by retrofit. | 0.88 | [skip (REQ-012 is All phases); single combined meta-test scanning x/ + docs/ + web/ (loses isolation)] |
+| D-070 | **G-003 firewall scope: `web/` importing `x/*/types` is app-layer consumption, not a cross-`x/` production import.** G-003 (production import firewall) prohibits production struct imports across `x/<module>/types` packages. `web/` is not an `x/` module — it is the application layer that consumes protocol types, exactly as a future `cmd/oyd` would. The G-003 firewall stays intact: no `x/` module gains a production import of another `x/` module's types via `web/`. GRILL reviews this boundary. | G-003's intent is to prevent cross-module coupling inside the protocol layer. The application layer consuming types is the intended consumption direction. `web/` importing `x/identity/types` is no different from `cmd/oyd` importing it (when one exists). | 0.85 | [treat `web/` as an `x/` module (wrong — it is not protocol); forbid `web/` from importing `x/*/types` (would force TS/JSON fixtures, losing the grounding in locked constants)] |
+| D-071 | **"Sign up" = create a Reach + open a Stash atomically.** The Nomad entry path per `docs/nomads/reach.md` is "a Nomad starts with a Reach and a Stash". The signup form creates both atomically: a `Reach` with `IsNomad=true` + a `Stash` with `HolderID` matching the Reach's `HolderID` and `BalanceGrain` seeded to a test value (e.g., 500,000 Grain = 50 Bread). No KYC, no custodian (REQ-001 self-service principle). The UI labels this "Create a Reach" (lexicon-clean; "account" is banned). | The docs define the Nomad starting state as Reach + Stash. Creating only a Reach would leave the Nomad unable to view a Stash dashboard (P2) — the atomic creation matches the docs and makes the happy path contiguous. | 0.82 | [create Reach only, defer Stash creation to a separate flow (fractures the happy path); create Reach + Stash + Window all at signup (over-scope for an MVP)] |
+| D-072 | **Phase ordering** (provisional, planner finalizes): P1 Web foundation + Reach signup + lexicon firewall extension (REQ-040 + REQ-045 — same `web/` territory, vertical slice, firewall-first) → P2 Stash dashboard (REQ-041, depends on Reach existing) → P3 Window authorization (REQ-042, depends on Stash existing) → P4 Standing + Freeholder signals (REQ-043, depends on Reach existing) → P5 Bloom accrual (REQ-044, depends on Stash existing) → P6 final review + audit + milestone ship. Each phase independently shippable; P1 lands the foundation + firewall first (lexicon-clean by construction). | P1 bundles the web foundation + Reach signup + the firewall extension (same `web/` territory, vertical slice). P2..P5 each add one screen, ordered by the Nomad happy path (Reach → Stash → Window → Standing → Bloom). Vertical slices, each phase shippable. | 0.82 | [different wave ordering; bundle Stash + Window in one phase] |
+| D-073 | **Bread-scale source of truth = `x/bread/types` code constants, NOT `docs/shared/bread-scale.md`.** The code constants (`GrainsPerBread=10000`, `BreadScaleAll()` table) are the locked, tested values; the docs table is aspirational/outdated (states 1,000× ratios that do not match the code). The UI uses the code constants for all Bread-scale conversions. A doc-fix for `docs/shared/bread-scale.md` is flagged as a P1+ follow-up (not a v0.6 deliverable — docs were a v0.3 deliverable; this is a doc-drift fix, not a UI feature). | The code constants are tested (`x/bread/types/types_test.go` asserts them); the docs are not. Using the code as the source of truth keeps the UI consistent with the protocol layer. | 0.90 | [use the docs table (wrong — not tested, disagrees with code); fix the docs in v0.6 (out of scope — doc-drift fix, not a UI feature)] |

-## IDEATE Traceability (Phase 0 — IDEATE stage, autonomy=full)
+## v0.4 Milestone Requirements (Refinement — NFR)
+
+v0.4 is a refinement-only NFR milestone: zero `feat:` phases. Scope sourced
+from v0.3 forward-references (REVIEW.md, AUDIT.md §193, GRILL.md G-014).
+Live-runtime promotions are out of scope (deferred to v0.5+). The D-001
+refinement-only filter applies to any IDEATE stage.
+
+| ID | Requirement | Source | Class | Priority | Status | Phase |
+|----|-------------|--------|-------|----------|--------|-------|
+| REQ-029 | Lexicon firewall: shared `lexicon.SyntheticBannedStrings()` helper — 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 source so a future banned-term addition updates both firewalls from one place | GRILL G-014 | refactor/test | High | Complete | v0.4/P1 |
+| 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 | test | High | Complete | v0.4/P1 |
+| REQ-031 | x/* lifecycle type shape-divergence review + alignment fixes — audit non-must-have lifecycle types across modules flagged by AUDIT §193; align shapes where divergent (no behavioral change) | AUDIT.md §193 | refactor/quality | Medium | Complete | v0.4/P2 |
+| REQ-032 | Docs build CI — Gitea Actions workflow that runs `go test ./...` (lexicon firewall) + `mkdocs build` on every push; upload the built `site/` as a CI artifact.

+
+## Milestone v0.4 Summary (Refinement — NFR) — COMPLETE
+
+- 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 Milestone Requirements (Bearers Runtime — Feature)
+
+v0.5 promotes the v0.3 Bearers skeletons from type+keeper-stub layers to
+live runtime behavior (keeper message handlers + simtest-grade end-to-end
+flows). No live chain launch (D-020 continues to govern network deployment);
+runtime = keeper handlers + simtest, not mainnet. Sourced from the v0.3/v0.4
+deferred items (D-050, PROJECT.md v0.4 out-of-scope, ROADMAP Phase 3 runtime).
+
+| ID | Requirement | Source | Class | Priority | Status | Phase |
+|----|-------------|--------|-------|----------|--------|-------|
+| REQ-033 | Exit layer runtime — `x/exit` DEX swap routing + `x/bridge` L2↔L1 IBC packet handlers; promotes REQ-010 from skeleton → runtime (simtest-grade message handlers; live DEX/IBC channels deferred) | PROJECT.md v0.4 OOS / D-050 | feat | High | Complete | v0.5/P1 |
+| REQ-034 | Bearers transport runtime — OY-SAT + OY-QR bearer transport message handlers in `x/bearers` (extends REQ-019/REQ-022); session lifecycle in simtest (hardware integration deferred) | PROJECT.md v0.4 OOS | feat | Medium | Complete | v0.5/P2 |
+| REQ-035 | Anchors onboarding runtime — `x/partner` Anchor tier credential issuance + revocation handlers (extends REQ-018/REQ-023); credential lifecycle in simtest (real institutional onboarding deferred) | PROJECT.md v0.4 OOS | feat | Medium | Complete | v0.5/P3 |
+| REQ-036 | Hub API B2B runtime — `x/hub` custody, lending primitive, compliance message handlers; keeper handlers + simtest (real B2B suite deferred) | PROJECT.md v0.4 OOS | feat | High | Complete | v0.5/P4 |
+| REQ-037 | Services runtime — `x/services` Care / SIM / Vault / Mail service lifecycle handlers; runtime handlers + simtest (live service integrations deferred) | PROJECT.md v0.4 OOS | feat | Medium | Complete | v0.5/P5 |
+| REQ-038 | Bond market depth runtime — `x/bond` Growth Bonds + secondary-market matching handlers (extends REQ-021/REQ-026); matching engine + simtest (live market depth deferred) | PROJECT.md v0.4 OOS | feat | High | Complete | v0.5/P6 |
+| REQ-039 | Council governance runtime — `x/council` Proposal/VoteOption enum types (AUDIT §193 P1-1, deferred from v0.4) + Voice lifecycle handlers; governance message handlers + simtest (Mission Lock const firewall intact per G-003; SignalKind 4→5 expansion deferred to v0.6+) | AUDIT §193 P1-1 / D-050 | feat | Medium | Complete | v0.5/P7 |
+
+> REQ-033..REQ-039 are NEW in v0.5. All are `feat`-class (runtime promotion
+> from skeleton). No breaking schema changes; locked-const firewall intact
+> (Mission Lock non-amendable). The final-phase audit enforces the feature
+> purity gate (no breaking schema changes; G-003 production firewall intact;
+> G-006 go.mod unchanged unless a runtime dep is GRILL-approved).
+
+## Milestone v0.5 Summary (Bearers Runtime — Feature) — COMPLETE
+
+- 7 v0.5-scope REQs shipped as feature (runtime promotion from skeleton): REQ-033, REQ-034, REQ-035, REQ-036, REQ-037, REQ-038, REQ-039
+- 8 modules promoted to runtime (keeper MsgServer handlers + simtest-grade end-to-end flows): x/exit, x/bridge, x/bearers, x/partner, x/hub, x/services, x/bond, x/council
+- cosmos-sdk v0.50.8 + ibc-go v8.2.1 added (D-055/D-062, G-006 controlled exception — scoped to runtime phases; types/ packages stay dep-free)
+- G-003 production firewall intact (expected_keepers.go interfaces; no production struct imports across x/<module>/types)
+- Locked-const firewall intact: all v0.1..v0.4 consts unchanged (ExitStatusCount=5, BridgeStatusCount=4, BearerTypeCount=6, OYSATLink.SurveillanceResistant=true, PartnerTierCount=4, HubServiceCount=3, LendingCouponCapBps=800, LendingCouponFloorBps=0, ServiceKindCount=4, CouponCapBps=800, CouponFloorBps=0, CouncilKindCount=3, SignalKindCount=4, MissionLockAmendable=false); v0.5 additions additive (AnchorCredentialStatusCount=4, WatcherVetoQuorum default 6 param-tunable)
+- 5 GRILL decisions ratified: D-055 (cosmos-sdk dep), D-062 (version pin), D-063 (bond CLOB REJECT above 800bps), D-064 (MissionLockAmendment reject-at-ValidateBasic), D-065 (Watcher Veto quorum default 6)
+- 8 binding fixes landed: G-017 (NoWithVeto test reconciled), G-018 (go 1.22 build gate), G-019 (ImpliedCoupon helper + boundary test), G-020 (WatcherVetoQuorum bounds [2,9]), G-021 (IBC replay ERROR), G-022 (baseline stubs documented), G-023 (keeper/msg_server.go ownership split), G-024 (types/ tests stdlib-only)
+- Coverage ≥80% on all 8 keeper packages: x/exit/keeper 85.0%, x/bridge/keeper 82.1%, x/bearers/keeper 91.2%, x/partner/keeper 87.6%, x/hub/keeper 90.0%, x/services/keeper 91.5%, x/bond/keeper 92.5%, x/council/keeper 90.3%
+- 34 packages green (no regression on v0.1..v0.4 baseline)
+- Tags: v0.4.0 (P0) -> v0.4.1 (P1) -> v0.4.2 (P2) -> v0.4.3 (P3) -> v0.4.4 (P4) -> v0.4.5 (P5) -> v0.4.6 (P6) -> v0.4.7 (P7) -> v0.4.8 (P8 = v0.5 milestone release)
+- Tag-line note: v0.5 (feature) ships on the v0.4.x patch line (config tag_base). The v0.4.8 milestone release IS the deliverable (D-008 — final phase patch IS the milestone release; no separate minor tag).
+- 5 P1+ issues flagged for v0.6+ mainnet-readiness (governance spam deposit, CLOB front-running/batch auction, real IBC light-client simtest, CLOB prefix-key perf, emitMatchEventHook testability)
+
+## v0.6 Milestone Requirements (Nomad Web UI — Feature)
+
+v0.6 is the project's first UI milestone. It delivers a working prototype Web
+UI where a person can sign up to be a Nomad (create a Reach + open a Stash)
+and exercise basic functionality around the (Reach, Stash) components, plus
+Window authorization, Standing progress, and Bloom accrual views. All data is
+generated as test fixtures — no real blockchain interaction (D-020 continues).
+The UI is a greenfield Go `html/template` + HTMX layer served by a Go mock HTTP
+server (`web/`) that instantiates the real `x/*/types` structs from in-memory
+fixtures. No keeper, no Cosmos runtime, no `app.go`.
+
+| ID | Requirement | Source | Class | Priority | Status | Phase |
+|----|-------------|--------|-------|----------|--------|-------|
+| REQ-040 | Nomad Reach signup Web UI — Go HTTP mock server (`web/main.go`, Go 1.22 `net/http.ServeMux`, mock store) + "Create a Reach" form (POST) + Reach list/detail views; grounds the UI in `x/identity/types.Reach`. "Sign up" maps to "Create a Reach" (the word "account" is banned per REQ-012). Signup atomically creates a Reach (`IsNomad=true`) + a Stash (per D-071, Nomad starts with both). | user `--ideate` request + D-066/D-067/D-068/D-071 | feat | High | Pending | v0.6/P1 |
+| REQ-041 | Stash dashboard Web UI — balance in Grain + Bread-scale conversion (using `x/bread/types.BreadScaleAll()` + `GrainsPerBread=10000`, per D-073 code constants are the source of truth) + 90-day maturity progress bar (`x/stash/types.StashActivity.IsMature`, `MaturityThresholdDays=90`). | user `--ideate` request + D-073 | feat | High | Pending | v0.6/P2 |
+| REQ-042 | Window authorization Web UI — form to open a Window (scope + duration + rate-limit) delegating to a service, lifecycle view (Open→Active→Revoked/Expired via `x/window/types.Window.Activate/Revoke/Expire`), audit log (`AuditEntry`). | user `--ideate` request | feat | Medium | Pending | v0.6/P3 |
+| REQ-043 | Standing + Freeholder signals progress Web UI — computed from mock `Rating`/`Vouch`/`Slash` records using the locked constants + `GetStandingBucket`/`ComputeDiversityBonus`/`GetVoucherWeight`; 4-signal progress (`FreeholderSignals.IsFreeholderEligible` — StashMaturity, MultiDomainStanding, CommittedCapital, CommunityEndorsement). | user `--ideate` request | feat | Medium | Pending | v0.6/P4 |
+| REQ-044 | Bloom accrual Web UI — per-Stash `BloomRecord` view (`AccruedGrain`, `RateBasisPoints`, `LastAccrualBlock`), computed from mock data; shows the 4.5% target rate (`TargetBloomRateBasisPoints=450`). | user `--ideate` request | feat | Low | Pending | v0.6/P5 |
+| REQ-045 | Extend REQ-012 lexicon firewall to scan `web/templates/**` + `web/static/**` + `web/**/*.go` (new `lexicon_meta_web_test.go`, package `lexicon_meta_web`, subdir `lexicon_meta_web/`). Mirrors the `lexicon_meta_docs` pattern with G-013 walk-coverage + G-009 self-test + G-014 shared `SyntheticBannedStrings()`. Firewall-first: lands in P1 before content (P2..P5). | D-069 + RESEARCH D-075 | test/quality | High | Pending | v0.6/P1 |
+
+> REQ-040..REQ-045 are NEW in v0.6. REQ-040..REQ-044 are `feat`-class (UI
+> screens); REQ-045 is `test` (lexicon firewall extension). No breaking schema
+> changes; G-003 production firewall intact (`web/` is app-layer, not an `x/`
+> module); G-006 go.mod unchanged (HTMX is a vendored static asset, not a Go
+> dep). The final-phase audit enforces the feature purity gate.
+
+## IDEATE Traceability (Phase 0 v0.6 — IDEATE stage, autonomy=full)
 
 The IDEATE stage ran the three ideation tiers (mechanical, backend-enriched,
-cross-project) on the v0.3 milestone scope and ratified 8 ideas (IDEATE-01..
-IDEATE-08) at full autonomy. Each IDEATE-NN maps to a REQ-ID in the v0.3
-requirements table above. Mechanical tier: no `lessons:`/`compound:` tags in
-v0.1/v0.2 history (convention unused); one historical escalation (milestone
-release pending — no remote) resolved in v0.2; v0.2 closed clean (9/9 REQs,
-303 tests, ≥95.9% coverage). Backend-enriched + cross-project tiers confirmed
-the docs deliverable + Bearers skeleton bundle (D-034) and the firewall-first
-ordering (D-044). Defaults accepted per full autonomy.
+cross-project) on the v0.6 milestone scope and ratified 6 ideas (IDEATE-09..
+IDEATE-14) at full autonomy. Each IDEATE-NN maps to a REQ-ID in the v0.6
+requirements table above. The user pre-validated the 5 screens + stack via
+interactive questions during CLARIFY (Go html/template + HTMX, Go mock API
+server, new `web/` dir, all 5 screens); IDEATE ratifies that validation.
+
+Mechanical tier: v0.5 closed clean (7/7 REQs, 8 keeper packages ≥80% coverage,
+G-003/locked-const firewalls intact, 5 P1+ flagged for v0.7+ mainnet-readiness);
+no `lessons:`/`compound:` tags in v0.1..v0.5 history (convention unused).
+Backend-enriched tier: confirmed the mock-server-over-real-Go-types approach
+grounds the UI in the locked constants (D-067/D-073). Cross-project tier: no
+applicable cross-project patterns (this is the project's first UI; no prior UI
+conventions to inherit). Defaults accepted per full autonomy.

 Notes:
-- IDEATE-01/02 (docs deliverable + firewall) are the user's `--ideate` request
-  ratified via D-042/D-043/D-045.
-- IDEATE-03..08 (Bearers skeleton) are the ROADMAP Phase 3 subset bundled into
-  v0.3 per D-034.
-- IDEATE-02 lands in P1 (firewall-first) BEFORE IDEATE-01 content (P2/P3) per
-  D-044 — docs are lexicon-clean by construction.
-- IDEATE-03..05 ship in P4 (Bearers skeleton I); IDEATE-06..08 ship in P5
-  (Bearers skeleton II) — vertical slices, each phase independently shippable.
+- IDEATE-09/14 ship in P1 (web foundation + firewall-first, same `web/` territory — vertical slice).
+- IDEATE-10..13 ship in P2..P5 (one screen per phase, ordered by the Nomad happy path: Reach → Stash → Window → Standing → Bloom).
+- The D-001 refinement-only filter does NOT apply (v0.6 is a feature milestone, not NFR).

+

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

+| x/hub/types | 93.3% | ✓ | 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**
+**P1+ findings: 0 P1, 3 P2 (all nits, post-hoc, non-blocking)**

+# 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**

+### Coverage detail (8 keeper packages — D-054 simtest grade)
+
+| Package | Coverage |
+|---|---|
+| x/exit/keeper | 85.0% |
+| x/bridge/keeper | 82.1% |
+| x/bearers/keeper | 91.2% |
+| x/partner/keeper | 87.6% |

+| x/services/keeper | 91.5% |
+| x/bond/keeper | 92.5% |
+| x/council/keeper | 90.3% |
+
+All 8 keeper packages exceed the ≥80% target (D-033); floor is 82.1% (x/bridge).
+
+---
+
+## 1. Per-Lens Findings
+
+### 1.1 Correctness (backend-engineer lens) — **PASS** (confidence 0.88)
+
+**MsgServer state-machine ordering.** All 8 keepers follow the mandated ordering
+`ValidateBasic → keeper authz → state mutation → event emit`. Verified by reading
+the handler headers + bodies in `x/{exit,bridge,bearers,partner,hub,services,bond,
+council}/keeper/msg_server.go` — each handler's doc comment enumerates the ordering
+and the body implements it. No handler mutates state before `ValidateBasic`.
+
+**IBC handlers (x/bridge).** `OnRecvPacket` writes the in-flight record after mint
+(A-513 replay protection). `OnAcknowledgementPacket` deletes the in-flight record on
+first ack and **returns ERROR** on a second ack (`ibc_module.go:314-316` — G-021 landed).
+`OnTimeoutPacket` refunds exactly-once via the `Refunded` flag guard (`ibc_module.go:
+349-353` — A-513 landed). The `Refunded` flip is state-write-first (A-521 idempotency
+pattern).
+
+**CLOB matching (x/bond).** Price-time priority FCFS via `sortRestingBook` (sort by
+price, then sequence — `clob.go:229-249`). Per-match REJECT above 800 bps via
+`ImpliedCoupon > CouponCapBps` (`clob.go:174-179` — D-063 landed). The G-019
+`ImpliedCoupon` helper is the single formula used by both match and clamp
+(`clob.go:108-115`). Boundary unit test covers 800/801/799 bps
+(`msg_server_simtest_test.go:830+`).
+
+**Council governance (x/council).** `MsgSubmitProposal.ValidateBasic` rejects the
+`MissionLockAmendment-Rejected` kind (`types_test.go:760-777` — D-064 landed). The
+handler ALSO rejects it at the kind-switch as defence-in-depth (`msg_server.go:141-
+144`). Veto quorum default 6 with `Params.Validate` bounds [2,9] (`types.go:194-204`
+— D-065 + G-020 landed). Single-Veto-no-block is enforced by the quorum rule.
+
+**OY-QR one-shot (x/bearers).** `ConsumeOYQR` flips `consumed=true` BEFORE the
+`BreadKeeper.TransferGrain` effect (`msg_server.go:354-355` — A-521 landed). A replay
+finds `consumed==true` and returns an error (`msg_server.go:336-337`). A failed
+transfer rolls back the consumed flip (SDK store atomicity — `msg_server.go:365-369`).
+
+**Compliance-before-custody (x/hub).** `CustodyReleaseAsset` consults the
+ComplianceKeeper shim's `IsCompliant` BEFORE releasing custody (`msg_server.go:220-
+226` — A-544 landed).
+
+**Lending coupon clamp (x/hub).** `RecordLendingPrimitive` clamps the coupon to
+`[LendingCouponFloorBps=0, LendingCouponCapBps=800]` via `ClampLendingCoupon`
+(`msg_server.go:268+` — A-543 landed).
+
+**Locked-const firewall verified** (all v0.1..v0.4 consts unchanged; v0.5 P7
+additive enums ProposalKindCount=4 / ProposalStatusCount=5 / VoteOptionCount=4):
+ExitStatusCount=5, BridgeStatusCount=4, BearerTypeCount=6 (via `len(AllBearers())`),
+OYSATLink.SurveillanceResistant=true, PartnerTierCount=4,
+AnchorCredentialStatusCount=4, PartnerStatusCount=4, HubServiceCount=3,
+LendingCouponCapBps=uint32(800), LendingCouponFloorBps=uint32(0), ServiceKindCount=4,
+CouponCapBps=800, CouponFloorBps=0, OrderSideCount=2, OrderStatusCount=3,
+CouncilKindCount=3, SignalKindCount=4, MissionLockAmendable=false (council + pact).
+All match the spec values.
+
+### 1.2 Testing (security-engineer lens) — **PASS** (confidence 0.87)
+
+**Coverage.** All 8 keeper packages ≥80% (82.1%..92.5% — verified by `go test -cover`).
+
+**G-017 reconciliation.** `TestTallyResultNoWithVetoDefaultZero` (renamed from the
+v0.2 `TestTallyResultNoWithVetoAlwaysZero`) and the new
+`TestTallyResultNoWithVetoPopulatedByQuorum` BOTH pass
+(`x/council/types/types_test.go:255-304` — verified by running both with `go test
+-v`). The v0.2 regression protection is preserved (renamed + re-scoped, NOT
+deleted); the v0.5 populated case is covered by the new test.
+
+**G-019 boundary test.** `TestImpliedCouponBoundary` covers price-bps 9200 (→800,
+at cap), 9199 (→801, REJECTED), 9201 (→799, in-band) at
+`x/bond/keeper/msg_server_simtest_test.go:830+`. Plus
+`TestImpliedCouponBoundaryAtCapClears` and `TestImpliedCouponBoundaryAboveCapRejected`
+exercise the full match path at the boundary.
+
+**G-024 stdlib-only invariant tests.** `grep -rln "cosmos-sdk\|sdk.Msg\|sdk.Context"
+x/*/types/*_test.go` returns ZERO hits — invariant/lexicon tests remain stdlib-only.
+
+**Replay/timeout/negative tests.** `x/bridge/keeper/msg_server_simtest_test.go`
+exercises the second-OnAck-ERROR (G-021) and timeout-refund-exactly-once (A-513).
+`x/bearers/keeper/msg_server_simtest_test.go` exercises the consumed-before-transfer
+(A-521) + replay reject. `x/council/keeper/msg_server_simtest_test.go` exercises the
+MissionLockAmendment reject + Veto quorum. All green.
+
+**Simtest happy-path scenarios.** The 8 simtest files cover the MVP/UX flows: bridge
+ICS-20 recv/ack/timeout, bearers OY-QR consume, partner anchor credential issuance,
+hub custody release + lending, services lifecycle, bond CLOB match, council
+proposal/vote/tally.
+
+### 1.3 Security (security-engineer lens) — **PASS** (confidence 0.86)
+
+**G-003 production firewall.** A sed-based by-module scan of all non-test `.go`
+files under `x/` returns ZERO cross-module `openyield/x/<other>/{types,keeper}`
+imports. All cross-module coupling is via `expected_keepers.go` interfaces (8 files,
+one per module). The existing G-003 import-invariant test (`x/window/types/
+types_test.go:437`) auto-covers the new files and passes.
+
+**Locked-consts unchanged.** Verified by direct `grep` of every const listed in the
+review brief (see §1.1). The v0.5 P7 enums are ADDITIVE (new types), not amendments
+— feature purity gate satisfied.
+
+**G-018 go.mod go directive.** `go.mod` line 3: `go 1.22` (NOT bumped). The cosmos-sdk
+v0.50.8 + ibc-go v8.2.1 transitive tree builds under go 1.22 (G-018 hard gate green —
+`go build ./...` exits 0).
+
+**G-020 WatcherVetoQuorum bounds.** `Params.Validate()` rejects `< 2` and `> 9`
+(`x/council/types/types.go:199-204`). The bounds [2,9] forbid single-Veto-block
+(min 2) and unsatisfiable quorum (max 9 — the Watcher set size per REQ-004).
+
+**Lexicon firewall green.** `go test -run TestLexiconMeta ./...` green across all
+new runtime files (no banned terms in x/ or docs/).
+
+**IBC denom trace parser pinned to ICS-20 v1.** `ValidateDenomTrace` +
+`ParseDenomTrace` (`x/bridge/keeper/ibc_module.go:101-132`) parse the
+`transfer/channel-N/<denom>` shape (ICS-20 v1). No IBC-v2/Eureka parsing.
+
+### 1.4 Performance (backend-engineer lens) — **PASS** (confidence 0.80)
+
+**CLOB matching.** `matchTaker` sorts the resting book once (`sortRestingBook`, O(n
+log n)) then walks in price-time order, stopping at the first non-crossing price
+(`clob.go:155-207`). No quadratic scan. The book load (`restingBookForBond`) is
+O(n) over resting orders for the bond; acceptable for simtest-grade depth. A
+production keeper would use prefix-key iteration; the simtest-grade `AllRestingOrders`
++ filter is O(n) and adequate (no hot-path concern at simtest depth).
+
+**Keeper stores.** All keepers use prefix-keyed store access (StoreKey + per-entity
+prefixes). No full-table scans in the handler hot paths (the CLOB book load is the
+only O(n) walk and it is bounded by resting orders for one bond).
+
+**Hot-path allocations.** No obvious hot-path allocations in the match loop (the
+`filledOrderIDs` slice grows by append; the resting book is a single allocation).
+Acceptable for simtest grade.
+
+### 1.5 Maintainability (lead-developer lens) — **PASS** (confidence 0.85)
+
+**Code style consistency.** The 8 runtime modules follow the v0.1..v0.4 skeleton
+conventions: `types/` package owns structs/enums/consts/ValidateBasic; `keeper/`
+owns the MsgServer + state; `module.go` owns RegisterServices; `expected_keepers.go`
+owns the cross-module interface shims. Consistent across P1..P7.
+
+**expected_keepers.go interface pattern.** All 8 modules ship a `types/
+expected_keepers.go` defining the cross-module keeper INTERFACES (BridgeKeeper,
+HubKeeper, BreadKeeper, WatcherKeeper, StandKeeper, GuildKeeper, ComplianceKeeper).
+No struct imports. The pattern is uniform.
+
+**Commit discipline.** All 8 phase merges carry `---ci---` blocks (verified by `git
+log --grep "---ci---"`). The phase commits follow the `checkpoint(pN): v0.5 phase N
+complete → v0.4.N` pattern.
+
+### 1.6 Adversarial (ci-security-auditor lens) — **PASS** (confidence 0.82)
+
+**What would break at mainnet?**
+- **Simtest vs real IBC light clients.** The bridge simtest uses in-memory
+  `sdk.Context` + stub BreadKeeper/WatcherKeeper (G-022 — baseline keepers remain
+  empty stubs). Real IBC light-client verification (client state, consensus state,
+  proofs) is NOT exercised — this is D-054 simtest grade, not mainnet. Mainnet
+  rollout requires wiring real ibc-go light clients (out of v0.5 scope). FLAG for
+  post-hoc (P1, maintainability) — the simtest does NOT prove IBC proof verification.
+- **Custody key rotation.** `x/hub/keeper/keyring_mem.go` is an in-memory keyring
+  (D-058). Rotation is modelled via `Status` reporting active key version; no
+  cross-block caching. Mainnet requires a real KMS-backed keyring (out of scope).
+- **CLOB front-running.** The CLOB is per-tx matching (no batch auction); a
+  front-runner with tx-ordering advantage could sandwich. D-054 simtest grade does
+  not model mempool ordering. FLAG for post-hoc (P1, adversarial) — a per-tx CLOB is
+  front-running-exposed at mainnet; a batch auction or commit-reveal is a v0.6+
+  design decision.
+- **Governance proposal spam.** `MsgSubmitProposal.ValidateBasic` checks fields +
+  kind but does NOT bond a deposit. A spammer could flood Pending proposals. The
+  keeper `SubmitProposal` does not charge a fee. FLAG for post-hoc (P1, security) —
+  no proposal deposit/bond at v0.5 simtest grade; mainnet needs a deposit gate
+  (standard x/gov pattern).
+
+**Mission-Lock const firewall bypass?** `MsgSubmitProposal.ValidateBasic` rejects
+the `MissionLockAmendment-Rejected` kind (D-064). The handler ALSO rejects it at
+the kind-switch (`msg_server.go:141-144` — defence in depth). No custom message can
+reach the handler with that kind: the MsgServer registration
+(`x/council/module.go:49` `RegisterServices`) wires only `types.MsgServer`
+(scaffolding) + the backend-implemented handler bodies (G-023 ownership split). A
+custom message would need a new `Msg*` type + a new `ValidateBasic` — both are
+additive and would be caught at code review. The const `MissionLockAmendable=false`
+is the firewall; `ValidateBasic` + the handler switch are the gates. Sound.
+
+**Double-spend via IBC replay?**
+- **Second OnAck (G-021).** Returns ERROR (not silent no-op) — `ibc_module.go:314-
+  316`. The in-flight record is deleted on first ack; a second ack finds no record
+  and errors. The relayer sees the failure. No double-mint (mint happens once on
+  OnRecv; the ack path only deletes the in-flight record).
+- **Timeout refund (A-513).** `OnTimeoutPacket` refunds via the `Refunded` flag
+  guard. A second timeout finds `Refunded==true` and no-ops (benign — the refund
+  already happened). A timeout on an already-acked packet finds no in-flight record
+  and no-ops (benign — the ack path already finalized). The `Refunded` flip is
+  state-write-first. No double-refund. Sound.

+## 2. GRILL Fix Verification (G-017..G-024)
+
+| ID | Fix | Landed? | Evidence |
+|---|---|---|---|
+| **G-017** | NoWithVeto regression-test reconciliation (rename + new test) | ✅ LANDED | `x/council/types/types_test.go:255` `TestTallyResultNoWithVetoDefaultZero` (renamed); `:271` `TestTallyResultNoWithVetoPopulatedByQuorum` (new). Both pass (`go test -v`). |
+| **G-018** | cosmos-sdk dep is a HARD go 1.22 build gate | ✅ LANDED | `go.mod:3` `go 1.22` (NOT bumped); `go build ./...` exits 0 under go 1.22 with cosmos-sdk v0.50.8 + ibc-go v8.2.1 transitive tree. |
+| **G-019** | CLOB ImpliedCoupon helper + boundary test (800/801/799) | ✅ LANDED | `x/bond/keeper/clob.go:108` `ImpliedCoupon(priceBps, principalGrain)`; `msg_server_simtest_test.go:830` `TestImpliedCouponBoundary` covers 9200/9199/9201 → 800/801/799. |
+| **G-020** | WatcherVetoQuorum Params.Validate bounds [2,9] | ✅ LANDED | `x/council/types/types.go:199-204` rejects `< 2` and `> 9`; `types_test.go:735` `TestParamsValidateBounds` covers 0/1/2..9/10. |
+| **G-021** | IBC second OnAck returns ERROR (not silent no-op) | ✅ LANDED | `x/bridge/keeper/ibc_module.go:314-316` returns `fmt.Errorf("bridge: replay detected — no in-flight record ... (already acknowledged)")`. |
+| **G-022** | Baseline keeper stubs documented + not promoted | ✅ LANDED | `x/{mirror,forge,still,watcher,bread}/keeper/` dirs all EMPTY (verified by `ls`). Each runtime keeper's msg_server.go documents the "nil-shim behavior (simtest wiring)" pattern. |
+| **G-023** | keeper/msg_server.go ownership (cosmos scaffolds, backend implements) | ✅ LANDED | Structural check: `module.go` (cosmos scaffolding) wires RegisterServices; `keeper/msg_server.go` holds the backend-implemented handler bodies. Pattern consistent across all 8 modules. |
+| **G-024** | types/ invariant tests stdlib-only (no cosmos-sdk import) | ✅ LANDED | `grep -rln "cosmos-sdk\|sdk.Msg\|sdk.Context" x/*/types/*_test.go` returns ZERO hits. Invariant/lexicon tests remain stdlib-only; only `msg_*.go` imports `sdk.Msg`. |
+
+**All 8 GRILL fixes (G-017..G-024) LANDED with evidence.**
+
+---
+
+## 3. P0 Issues (auto-applied in this phase)
+
+**0.** No P0 (critical) issues found. The milestone ships clean:
+- `go build ./...` green
+- `go test ./...` green (729 tests)
+- All 8 GRILL fixes landed with evidence
+- All locked-consts unchanged
+- G-003 production firewall intact
+- G-018 go 1.22 build gate green
+- Coverage ≥80% on all 8 keeper packages
+
+No source edits were required; no `fix(P8): ...` commits were created.
+
+---
+
+## 4. P1+ Issues (flagged for post-hoc review — do NOT block ship)
+
+**1.** [P1, security] **No proposal deposit/bond at v0.5 simtest grade.** `MsgSubmitProposal.ValidateBasic` checks fields + kind but does NOT bond a deposit; the keeper does not charge a fee. A mainnet spammer could flood Pending proposals. Recommend post-hoc: add a deposit gate (standard `x/gov` pattern) in a v0.6+ milestone before mainnet. Not a v0.5 ship blocker (simtest grade does not model spam economics).
+
+**2.** [P1, adversarial] **CLOB per-tx matching is front-running-exposed at mainnet.** The CLOB matches per-tx (no batch auction); a tx-ordering-advantaged actor could sandwich. D-054 simtest grade does not model mempool ordering. Recommend post-hoc: evaluate a batch auction or commit-reveal for v0.6+ before mainnet. Not a v0.5 ship blocker (simtest grade).
+
+**3.** [P1, maintainability] **Simtest does NOT exercise real IBC light-client verification.** The bridge simtest uses in-memory `sdk.Context` + stub BreadKeeper/WatcherKeeper (G-022). Real IBC client state / consensus state / proof verification is NOT exercised. Mainnet rollout requires wiring real ibc-go light clients (out of v0.5 scope). Recommend post-hoc: a v0.6+ mainnet-readiness milestone exercises real light clients. Not a v0.5 ship blocker (D-054 simtest grade is explicit).
+
+**4.** [P2, performance] **CLOB `restingBookForBond` is O(n) over all resting orders.** The keeper loads `AllRestingOrders` then filters by `BondID` in Go. Acceptable for simtest depth; a production keeper would use a prefix-keyed store iteration scoped to the bond. Recommend post-hoc: prefix-key the book store by `BondID` for mainnet depth. Not a v0.5 ship blocker.
+
+**5.** [P2, maintainability] **`emitMatchEventHook` indirection in clob.go.** `clob.go` uses a package-level `var emitMatchEventHook func(...)` set by `msg_server.go` to avoid importing the sdk event package in `clob.go`. This is a pragmatic split but the package-level mutable var is a minor testability smell (a parallel test could race the hook). Recommend post-hoc: pass the event emitter as a Keeper field or a constructor injection. Not a v0.5 ship blocker (simtest is serial).
+
+---
+
+## 5. Overall Verdict
+
+### **PASS-WITH-FIXES** → **SHIP** (all GRILL fixes landed; no P0; P1+ flagged for post-hoc)
+
+The v0.5 (Bearers Runtime) milestone delivers the runtime promotion of 8 v0.3
+skeleton modules to live keeper `MsgServer` handlers + simtest-grade end-to-end
+flows (D-054). All 8 GRILL binding fixes (G-017..G-024) landed with evidence:
+
+- G-017 NoWithVeto reconciliation: renamed + new test, both pass.
+- G-018 go 1.22 hard build gate: `go.mod` go directive unchanged; build green.
+- G-019 ImpliedCoupon helper + boundary test (800/801/799): landed + tested.
+- G-020 WatcherVetoQuorum Validate bounds [2,9]: landed + tested.
+- G-021 IBC second-OnAck ERROR (not silent no-op): landed.
+- G-022 baseline keeper stubs documented + NOT promoted: 5 v0.1 keeper dirs empty.
+- G-023 keeper/msg_server.go ownership split: cosmos scaffolds, backend implements.
+- G-024 types/ invariant tests stdlib-only: zero cosmos-sdk imports in types tests.
+
+`go build ./...` + `go test ./...` green across all packages (729 tests). Coverage
+≥80% on all 8 keeper packages (82.1%..92.5%). All v0.1..v0.4 locked-consts unchanged;
+v0.5 P7 enums are additive (feature purity gate satisfied). G-003 production firewall
+intact (zero cross-module struct imports; expected_keepers.go interface pattern
+uniform). G-018 go 1.22 build gate green. Lexicon firewall green on all new files.
+
+No P0 (critical) issues found — no source fixes applied. 5 P1+/P2 issues flagged for
+post-hoc review (proposal deposit gap, CLOB front-running, simtest vs real IBC light
+clients, CLOB book O(n) load, emitMatchEventHook indirection) — none block the v0.5
+ship (all are mainnet-readiness concerns for v0.6+, consistent with D-054 simtest
+grade).
+
+**P0 fixes auto-applied: 0**
+**P1+ findings: 2 P1, 3 P2 (all post-hoc, non-blocking)**
+**Confidence in overall verdict: 0.86**

+generated as test fixtures — no real blockchain interaction (D-020 continues).
+Greenfield Go `html/template` + HTMX layer served by a Go mock HTTP server
+(`web/`) that instantiates the real `x/*/types` structs from in-memory
+fixtures. No keeper, no Cosmos runtime, no `app.go` (none exists in the repo).

+# OpenYield
+
+OpenYield is a jurisdiction-light, public-good mesh for **real production** — a
+protocol organized around Holders, Stands, and the Six Principles, designed to
+hold real value without the words or the shapes that invite capture. The mesh
+runs on OY Chain (Layer 1), a canonical state layer for the Bread unit, the
+Storage Pools (Stash, Vault, Root-Pool), Standing, Watcher attestations, and
+the Pact / Council / Partner surface. It is anti-greed by construction: Mission
+Lock fixes the Six Principles and fee covenant so no council can amend them,
+and the 8% coupon cap on bonds is a mission-locked ceiling, not a parameter.
+
+## The Six Principles
+
+1. **Real value** — the mesh holds real production, not speculation.
+2. **Sustainability** — fees are floored and capped; the protocol cannot drain its users.
+3. **Mission-lock** — the Six Principles and fee covenant are immutable; no council can amend them.
+4. **Openness** — anyone may join; the mesh is a public good.
+5. **Ownership** — Holders own their Stash and their Reach; custody is theirs.
+6. **Self-service** — a Holder can act without a custodian; the mesh is jurisdiction-light.
+
+## Bread unit & scale
+
+The unit of value is **Bread**, scaled in 11 tiers: **Grain → Crumb → Bread →
+Loaf → Batch → Cake → Bakery → Granary → Mill → Harvest → Earth.**
+
+## Status
+
+**v0.6 (Nomad Web UI) — in progress.** v0.5 shipped the Bearers Runtime
+(simtest-grade keeper handlers for 8 x/ modules). v0.6 adds the project's
+first UI: a Go `html/template` + HTMX prototype Web UI in `web/` where a
+visitor can sign up to be a Nomad (create a Reach + open a Stash) and
+exercise basic functionality around Reach, Stash, Window, Standing, and
+Bloom. All data is generated test fixtures — no real chain. See
+`.ciagent/oy/ROADMAP.md` for the phase plan and `.ciagent/oy/PROJECT.md`
+for governance.
+
+## Build & test
+
+OpenYield is pure Go with **zero external dependencies** (`go.mod` has no
+`require` lines; `go 1.22`). From the repo root:
+
+```sh
+go build ./...
+go test ./...
+```
+
+## Web UI
+
+The Nomad Web UI (v0.6) is a Go `html/template` server with HTMX progressive
+enhancement, served by a mock HTTP server in `web/` that instantiates the
+real `x/*/types` structs from in-memory fixtures. No node, no build step,
+no real chain. To run it:
+
+```sh
+go run ./web
+# opens on http://localhost:8080 (PORT env var overridable)
+```
+
+Five screens, all reachable from the home nav:
+
+- `/reach` — create a Reach (sign up to be a Nomad) + Reach list/detail
+- `/stash/{holderID}` — Stash dashboard (Grain balance + Bread scale + 90-day maturity)
+- `/window` — Window authorization (open/lifecycle/audit log)
+- `/standing/{reachID}` — Standing + Freeholder signals progress
+- `/bloom/{stashID}` — Bloom accrual view
+
+HTMX is a single vendored JS file (`web/static/htmx.min.js`), NOT a Go
+dependency — `go.mod` stays unchanged (G-006).
+
+## Docs
+
+The docs site is [MkDocs Material](https://squidfunk.github.io/mkdocs-material/)
+(a build-only Python dep; **not** a Go dep — `go.mod` is unchanged). To
+preview locally:
+
+```sh
+mkdocs serve
+# or build to a static site/ dir:
+mkdocs build
+```
+
+The site lives under `docs/` (see `mkdocs.yml` for the nav). Publishing CI is
+deferred to v0.4 (D-046); v0.3 ships the source.
+
+## Lexicon firewall
+
+OpenYield bans 10 financial terms as standalone words (REQ-012) across all Go
+source (`x/**/*.go`), all docs (`README.md` + `docs/**/*.md`), and all web UI
+files (`web/**/*.{html,js,go}`). The banned terms are the words you would
+expect a legacy financial institution to use; this README and the docs describe
+them only by their **safe replacements**, so the firewall itself never trips.
+The firewall is enforced in code by three sibling Go tests:
+
+- `lexicon_meta_test.go` (v0.2) — scans `x/**/*.go`.
+- `lexicon_meta_docs/lexicon_meta_docs_test.go` (v0.3) — scans `README.md` +
+  `docs/**/*.md`.
+- `lexicon_meta_web/lexicon_meta_web_test.go` (v0.6) — scans
+  `web/templates/**` + `web/static/**` + `web/**/*.go`.
+
+All three use `lexicon.FindBannedTerm` (word-boundary, case-insensitive), so
+"OpenYield" is safe (word-boundary does not match the banned term inside an
+identifier) but the standalone banned term is not — docs say **"real
+production"** / **"real return"**, and a Holder's identity is **Holder** /
+**Reach**, never the banned word for a custodial position. See
+`docs/shared/lexicon.md` for the glossary of safe replacements.
+
+## Governance
+
+- `.ciagent/oy/PROJECT.md` — full vision, decisions (D-0xx), assumptions.
+- `.ciagent/oy/PLANS.md` — phase plans (v0.1, v0.2, v0.3).
+- `.ciagent/oy/REQUIREMENTS.md` — REQ coverage matrix.
+- `.ciagent/oy/ROADMAP.md` — release roadmap.

+# Anchor Preview
+
+An **Anchor** (REQ-023) is the fourth and highest tier of the
+[Partner Spectrum](partner-spectrum.md) (REQ-018) — the first **institutional**
+Partner tier. Anchors are coming in v0.3 P4. This page previews what an Anchor
+is and what the v0.3 skeleton will deliver; the runtime behavior is deferred
+to v0.4+.
+
+## What an Anchor is
+
+An Anchor is a Partner that carries an **AnchorCredential**: a jurisdiction
+(e.g., "EU-MiCA"), a custody provider, and a set of attestation references.
+The Anchor tier is how the jurisdiction-light mesh interfaces with
+jurisdiction-bound institutional actors without becoming them. An Anchor
+holds a credential; the [Holder](../nomads/reach.md) still holds their
+[Stash](../nomads/stash.md). The mesh says **custody**, **compliance**, and
+**jurisdiction** — never the legacy institutional words banned by the
+[lexicon](../shared/lexicon.md).
+
+## What is coming in v0.3 P4
+
+v0.3 P4 (REQ-023) extends `x/partner` with the `AnchorCredential` struct and
+a `Partner.AnchorCredential()` accessor (returns nil for non-Anchor tiers).
+The four-tier `PartnerTier` enum (Op, Master Op, Pier, Anchor) is **unchanged**
+— v0.3 adds Anchor-specific fields, not a new tier. The custody-provider-id
+field is a by-ID-string reference to `x/hub` (the Hub API, coming in v0.3 P5),
+empty in the v0.3 skeleton because the Hub is not live until P5/v0.4. This is
+the P4→P5 ordering edge: `x/hub` in P5 references Anchor partner-ids from P4.
+
+## Why Anchors matter to a Freeholder
+
+A Freeholder engaging an Anchor gets a Partner with a verifiable credential
+and a custody/compliance relationship — useful for cross-jurisdiction routes
+and institutional [bonds](bonds.md). The Anchor's [Standing](standing.md) and
+attestations are visible so the Freeholder can verify the Anchor is real
+before opening a [Window](../nomads/window.md). See
+[Partner Spectrum](partner-spectrum.md) for the other three tiers, and
+[Councils & Voice](councils-voice.md) for how the Mesh Council can suspend or
+revoke an Anchor.
+
+## What v0.3 does not deliver
+
+The v0.3 skeleton is types + tests only (D-035): the `AnchorCredential`
+struct, the accessor, and the `ListAnchors()` keeper alias. Live custody
+routing, attestation verification, and the Hub API integration are v0.4+
+runtime work. See [Components](../reference/components.md) for the full
+module map.

+# Bonds
+
+A **Mesh Bond** (REQ-021, vision §17) is a [Stand](stands-guilds.md)-issued
+instrument that pays a **coupon** to its holder over a term and returns the
+principal at maturity. The coupon is bounded by a **mission-locked cap and
+floor**: 8% upper cap, 0% floor (locked `CouponCapBps = 800` and
+`CouponFloorBps = 0` in `x/bond`). The cap exists so the mesh cannot become a
+speculative market; the floor exists so the coupon cannot go negative.
+
+## The coupon clamp
+
+The coupon is clamped to `[floor, cap]` by the `Clamp` helper in `x/bond`
+(same shape as the [Fee Covenant](../shared/six-principles.md) clamp): a
+coupon above 8% is reduced to 8%; a coupon below 0% is raised to 0%; a coupon
+in range is unchanged. The clamp is a tested invariant: below floor → floor,
+above cap → cap, in range → unchanged. This is the Mission Lock's expression
+in the capital layer.
+
+## Why a cap
+
+OpenYield is a public-good mesh for **real production**, not a speculation
+engine. An uncapped coupon market would let a Stand offer arbitrarily high
+coupons to attract Bread, turning the mesh into a speculative race. The 8%
+cap bounds the coupon at a level consistent with real production returns, and
+the [Mission Lock](councils-voice.md) makes the cap non-amendable — no Council
+vote can raise it. The mesh says **coupon** and **real return**, never the
+passive-value or standalone-metric words banned by the
+[lexicon](../shared/lexicon.md).
+
+## The bond lifecycle
+
+A Bond moves through five states (locked `BondStatus` enum in `x/bond`):
+Issued → Active → Matured, with Defaulted and Repaid as terminal paths. The
+issuer is a Stand (referenced by stand-id); the principal is denominated in
+[Grain](../shared/bread-scale.md). The bond market is governed by the
+[Stand Council](councils-voice.md) for the issuing Stand.
+
+## Coming in v0.3 P5
+
+v0.3 P5 (REQ-026) extends the bond market with **Growth Bonds** (a coupon that
+grows over the term, still clamped to the 8% cap) and a **secondary market**
+(Buy/Sell orders on issued bonds). The 8% / 0% consts are unchanged — the
+D-028 regression firewall guarantees v0.3 cannot alter the v0.2 mission-locked
+ceiling. See [Partner Spectrum](partner-spectrum.md) for how Partners relate
+to the bond market, and [Anchor Preview](anchor-preview.md) for the
+institutional tier.

+# Councils & Voice
+
+OpenYield governs itself through three **Councils** (REQ-011, vision §19):
+the Mesh Council, the Guild Council, and the Stand Council. Each Freeholder
+participates through the Councils, weighted by **Voice** — a multi-source
+weight that combines [Stash](../nomads/stash.md), [Standing](standing.md),
+Vouch, Freeholder status, and Guild membership. The **Mission Lock** makes
+the covenant non-amendable: no Council can vote to change the
+[Six Principles](../shared/six-principles.md) or the fee covenant.
+
+## The three Councils
+
+- **Mesh Council** — the mesh-wide Council. Handles protocol-level proposals
+  that affect every Holder and every [Stand](stands-guilds.md).
+- **Guild Council** — the Council for [Guilds](stands-guilds.md). Handles
+  Guild-scope proposals, referenced by guild-id.
+- **Stand Council** — the Council for a single Stand, referenced by stand-id.
+  Handles Stand-scope proposals (e.g., Vault use, [Bond](bonds.md) issuance).
+
+The three-tier shape mirrors the three [Storage Pools](../shared/storage-pools.md):
+a Council exists at each layer where custody is held.
+
+## Multi-source Voice
+
+Voice is not one number. It is a weighted tally from five sources (locked as
+the `VoiceSource` enum in `x/council`): Stash, Standing, Vouch, Freeholder,
+and Guild. A Freeholder with high [Standing](standing.md) and a long-held
+Stash carries more Voice than a freshly-minted one. The
+[TallyResult](../reference/components.md) mirrors the Cosmos SDK `x/gov`
+shape so the governance layer can wire to standard tooling. The VoteOption
+enum is **Yes / No / Abstain** — there is no "no-with-veto", an anti-greed
+design choice.
+
+## Mission Lock
+
+The Mission Lock is a locked `const bool` in `x/council`
+(`MissionLockAmendable = false`). The Six Principles, the fee covenant
+(ceiling 0.1% / floor 0.01% / 1-Grain minimum), and the bond coupon cap
+([8% / 0%](bonds.md)) cannot be amended by any Council vote. This is the
+firewall that keeps the mesh a public good: governance can act *within* the
+covenant, never *on* the covenant.
+
+## How a Freeholder participates
+
+A Freeholder submits or votes on proposals in the Councils they belong to.
+Each vote is weighted by multi-source Voice; the tally follows `x/gov`
+semantics. See [Bonds](bonds.md) for the coupon cap the Mission Lock protects,
+and [Standing](standing.md) for the metric that weights a Freeholder's Voice.

+# Freeholders
+
+A **Freeholder** is a Holder who has earned all four Freeholder signals (REQ-005):
+a 90-day [Stash](../nomads/stash.md), a [Standing](standing.md) threshold of
+4.5★ or higher in 3 categories, the Capital signal, and the Vouch signal. A
+Freeholder is the active participant in the OpenYield mesh — they sit in
+[Stands & Guilds](stands-guilds.md), vote in the three
+[Councils & Voice](councils-voice.md), issue [Bonds](bonds.md), and relate to
+the four-tier [Partner Spectrum](partner-spectrum.md).
+
+## The four signals
+
+The signals are the gate to Freeholder participation. They are deliberately
+heterogeneous — no single input can be pumped — so the path resists gaming:
+
+- [Signals](signals.md) — the four Freeholder signals (REQ-005): 90-day Stash,
+  4.5★+ in 3 categories, Capital, Vouch.
+- [Standing](standing.md) — the Bayesian anti-gaming formula (REQ-006):
+  Bayesian prior + time-decay + diversity + voucher-weighting − slashes.
+- [Stands & Guilds](stands-guilds.md) — the nine Stand types (REQ-016) and
+  Guilds with free Hand-Passes (REQ-017).
+- [Councils & Voice](councils-voice.md) — the three Councils and the
+  non-amendable Mission Lock (REQ-011).
+- [Bonds](bonds.md) — the Mesh Bond Market, the 8% coupon cap / 0% floor
+  (REQ-021).
+- [Partner Spectrum](partner-spectrum.md) — the four Partner tiers (REQ-018):
+  Op, Master Op, Pier, Anchor.
+- [Anchor Preview](anchor-preview.md) — the first institutional Partner tier
+  (REQ-023), coming in v0.3 P4.
+
+## What a Freeholder does
+
+A Freeholder is a Holder who has crossed the signal gate. From there the mesh
+opens: a Freeholder joins a [Stand](stands-guilds.md) (or forms a Guild), votes
+in the [Councils](councils-voice.md) with multi-source Voice, issues or holds
+[Bonds](bonds.md) under the mission-locked coupon cap, and engages the
+[Partner Spectrum](partner-spectrum.md) — including the Anchor tier coming in
+v0.3. The covenant is the same for every audience; the Freeholder pages
+describe how it shows up in governance and capital.

+# Partner Spectrum
+
+OpenYield defines a four-tier **Partner Spectrum** (REQ-018, vision §13):
+**Op**, **Master Op**, **Pier**, and **Anchor**. Partners are the external
+actors a [Freeholder](index.md) interacts with through the mesh — service
+operators, route providers, and institutional bridges. The four tiers are
+locked as the `PartnerTier` enum in `x/partner` (exactly 4, regression-tested).
+
+## The four tiers
+
+- **Op** — a service operator. Runs a service a Holder uses through a
+  [Window](../nomads/window.md) (e.g., a Maps provider). The lightest tier.
+- **Master Op** — a senior operator. Coordinates multiple Ops or runs a
+  higher-trust service. "Op" is the safe short form; the full word is not
+  used as a standalone term.
+- **Pier** — a routing Partner. Connects the mesh to external venues (e.g.,
+  a DEX or an off-mesh service) and sources [Forex](../reference/components.md)
+  rates. Piers route; they do not custody Holder value.
+- **Anchor** — the first institutional Partner tier. Carries a credential
+  (jurisdiction, custody provider, attestations). See
+  [Anchor Preview](anchor-preview.md) for what is coming in v0.3 P4.
+
+## How Freeholders relate to Partners
+
+A Freeholder authorizes a Partner to act on their behalf through a scoped,
+time-limited, revocable [Window](../nomads/window.md) — never by handing over
+custody. The Partner holds a credential, not the Holder's [Stash](../nomads/stash.md).
+A Partner's [Standing](standing.md) is visible so a Freeholder can choose an
+operator with a real history over a freshly-spun-up alternative (see
+[Maps & Pay](../nomads/maps-pay.md)).
+
+## Partner status
+
+Each Partner has a status (locked `PartnerStatus` enum in `x/partner`):
+Pending → Active, with Suspended and Revoked as the governance paths. The
+[Mesh Council](councils-voice.md) can suspend or revoke a Partner. The four
+tiers and the status enum are unchanged by v0.3 — v0.3 only *extends*
+`x/partner` with the Anchor credential shape (REQ-023), not a new tier.
+
+See [Storage Pools](../shared/storage-pools.md) for why the mesh says
+"Holder" and "Reach" rather than the legacy custodial words, and
+[Bonds](bonds.md) for the coupon market a Partner may route to.

+# The Four Freeholder Signals
+
+The four **Freeholder signals** (REQ-005) are the gate to Freeholder
+participation. A [Holder](../nomads/reach.md) who earns all four becomes a
+[Freeholder](index.md) — eligible to join [Stands & Guilds](stands-guilds.md),
+vote in the [Councils](councils-voice.md), and issue [Bonds](bonds.md). The
+signals are deliberately heterogeneous: no single input can be pumped, so the
+path resists gaming.
+
+## 1. The 90-day Stash
+
+A Holder must hold a [Stash](../nomads/stash.md) continuously for 90 days
+(REQ-014). The signal is about **continuity, not size** — a small Stash held
+steadily counts. This filters out transient actors who spin up a position to
+game a vote and then leave. See [Storage Pools](../shared/storage-pools.md)
+for the three-pool model.
+
+## 2. Standing of 4.5★ or higher in 3 categories
+
+A Holder must earn a [Standing](standing.md) of 4.5★ or higher in **three
+distinct categories** (REQ-006). The diversity requirement is the anti-gaming
+core: a Holder cannot reach Freeholder by repeating the same action with the
+same counterparty. Three categories force breadth.
+
+## 3. Capital
+
+The Capital signal requires a Holder to hold a meaningful amount of
+[Bread](../shared/bread-scale.md) in their Stash. The threshold is set by the
+mesh [Councils](councils-voice.md) and is a stake, not a fee: the Holder keeps
+the Bread. Capital aligns the Freeholder's stake with the mesh.
+
+## 4. Vouch
+
+The Vouch signal requires another Freeholder to vouch for the Holder. A
+vouch from a high-[Standing](standing.md) Freeholder carries more weight
+(voucher-weighting), so a single colluding vouch cannot carry a Holder over
+the gate. Vouch is the social signal that ties the other three together.
+
+## Why four, not one
+
+Each signal covers a different attack surface: continuity (90-day Stash),
+breadth (3-category Standing), stake (Capital), and social trust (Vouch).
+Earning all four is the proof a Holder is a participant, not a transient
+gamer. See [Standing](standing.md) for the anti-gaming math, and
+[Bonds](bonds.md) for what a Freeholder can do once the signals are earned.

+# Bayesian Standing
+
+**Standing** (REQ-006) is a Holder's measured history on the mesh — the
+anti-gaming metric that gates [Freeholder](index.md) participation and weighs
+[Voice](councils-voice.md) in the [Councils](councils-voice.md). Standing is
+not a count of transactions and not a reputation score you can farm. It is a
+Bayesian score that resists the obvious attacks: volume spam, self-dealing,
+fake vouches.
+
+## The formula, at conceptual depth
+
+Standing combines four signals and a penalty:
+
+- **Bayesian prior + updates.** The mesh starts with a prior for each Holder
+  and updates it from each observed action. A burst of activity cannot
+  inflate Standing because the prior anchors it.
+- **Time-decay.** Old evidence decays, so a Holder cannot rest on a burst
+  from years ago. Standing reflects *recent, sustained* real production.
+- **Diversity weighting.** A Holder who acts across many services, many
+  [Stands](stands-guilds.md), and many [bearers](../nomads/bearers.md) accrues
+  more Standing than one who repeats the same action with the same
+  counterparty. Diversity is the anti-collusion lever.
+- **Voucher-weighting.** A vouch from a high-Standing Freeholder counts for
+  more than a vouch from a low-Standing one. This makes fake vouches expensive:
+  the voucher must themselves have Standing to lose.
+- **Minus slashes.** Bad behavior (failed attestations, broken Pacts) removes
+  Standing. Slashes are the penalty that bounds the upside of gaming.
+
+> The full sub-tables (priors, decay rates, diversity categories, slash
+> conditions) are deferred per PROJECT.md Q2. This page gives the conceptual
+> depth; the [nomads Standing page](../nomads/standing.md) gives the plain-
+> language version.
+
+## Why it cannot be gamed
+
+There is no single input a Holder can pump. Volume is bounded by the Bayesian
+prior; recency is bounded by time-decay; breadth is bounded by diversity;
+social trust is bounded by voucher-weighting; and any attempt that misfires
+costs Standing via slashes. The four signals (the [90-day Stash](signals.md),
+3-category threshold, Capital, Vouch) sit on top of this metric, so the
+Freeholder gate inherits the same anti-gaming property.
+
+## What Standing is not
+
+Standing is not a custodial position, a tier you buy, or legacy history. It
+is a measured, decayed, diversified Bayesian score. See
+[Storage Pools](../shared/storage-pools.md) for why the mesh says "Stash"
+rather than the legacy custodial words, and [Councils & Voice](councils-voice.md)
+for how Standing weights a Freeholder's vote.

+# Stands & Guilds
+
+A **Stand** is a governed group of Holders that holds a [Vault](../shared/storage-pools.md)
+in common (REQ-016). A **Guild** is a looser association of Holders that can
+pass value among its members for free (REQ-017). Both are the organizational
+layer a [Freeholder](index.md) joins after earning the four
+[signals](signals.md).
+
+## The nine Stand types
+
+OpenYield defines exactly nine Stand types (REQ-016, vision §11), locked as a
+const in `x/stand`:
+
+1. **Household** — a family-scale group.
+2. **Crew** — a working team.
+3. **Entity** — a single legal actor.
+4. **Co-op** — a cooperative.
+5. **Circle** — an affinity group.
+6. **Trust** — a trust arrangement.
+7. **Foundation** — a purpose-bound entity.
+8. **Confederation** — a federation of Stands.
+9. **Shadow** — a privacy-preserving Stand.
+
+A Stand's decision policy (threshold or weighted, mirroring the Cosmos SDK
+`x/group` shape) governs how its Vault is used. A Stand can also issue
+[Bonds](bonds.md) — the bond issuer is a Stand, referenced by stand-id.
+
+## Guilds and Hand-Passes
+
+A **Guild** is a looser association: it may affiliate with a Stand or stand
+alone. Inside a Guild, a **Hand-Pass** moves [Bread](../shared/bread-scale.md)
+between members at a **0% protocol fee** (REQ-017, locked `HandPassFeeBps = 0`
+in `x/guild`). The 0% fee is mission-locked: the mesh does not tax the social
+transfer of value among a self-organized group. See the
+[Fee Covenant](../shared/six-principles.md) for the broader fee shape.
+
+## How a Freeholder joins
+
+A Freeholder joins a Stand by becoming a member (the Stand's policy admits
+them) or forms a Guild as a founder. Membership is recorded in `x/stand`
+and `x/guild` respectively, by stand-id / guild-id and the member's
+[Reach](../nomads/reach.md). From a Stand a Freeholder gains Vault access and
+the ability to issue [Bonds](bonds.md); from a Guild a Freeholder gains free
+Hand-Passes with other members.
+
+See [Councils & Voice](councils-voice.md) for how Stands and Guilds each get a
+Council, and [Storage Pools](../shared/storage-pools.md) for the Vault layer.

+# Bearers
+
+The **bearers** (REQ-019) are how a Nomad reaches the mesh. OpenYield ships
+six bearers through a single **Unified Bearer Layer**: the mesh does not
+care which bearer a Holder uses — first-to-deliver-wins, and a Nomad can
+switch bearers without switching identity. The [Mirror](../shared/watchers-mirror.md)
+mirrors the canonical state to every bearer so a Nomad can read the mesh's
+real return on any of them.
+
+## The six bearers
+
+| Bearer | Live in v0.2 | What it is |
+|---|---|---|
+| **Internet** | yes | the default bearer; OY Chain over the open internet. |
+| **OY-BLE** | yes | Bluetooth Low Energy; short-range, peer-to-peer, no phone plan. |
+| **OY-WiFi-Direct** | yes | WiFi Direct; local mesh without an access point. |
+| **OY-LR** | yes | Long Range radio (LoRa-class); long-distance, low-bandwidth, surveillance-resistant. |
+| **OY-SAT** | coming (v0.3 P4) | satellite; offline coverage via a satellite constellation. |
+| **OY-QR** | coming (v0.3 P4) | signed QR code; one-shot offline transfer scanned by a peer. |
+
+## What this means for a Nomad
+
+A Nomad does not pick "the right bearer". The four already-live bearers
+(Internet, OY-BLE, OY-WiFi-Direct, OY-LR) cover the everyday situations:
+on the open internet, in a room with another Holder, in a local group with
+no router, or kilometers away with no infrastructure. OY-SAT and OY-QR
+extend that to true-offline paths and are coming in the next phase.
+
+## Surveillance resistance
+
+OY-LR, OY-BLE, OY-WiFi-Direct, OY-SAT, and OY-QR are designed to be
+surveillance-resistant: a Nomad can send or receive value without a
+phone plan, a SIM, or a custodial on-ramp. The bearer is the transport; the
+[Reach](reach.md) is the identity; the [Stash](stash.md) is the storage. None
+of them depends on a custodial position.
+
+## First-to-deliver-wins
+
+The Unified Bearer Layer is first-to-deliver-wins: if a Nomad sends a
+transfer over two bearers at once, the mesh accepts the first one that
+arrives and drops the duplicate. This is why a Nomad can switch bearers
+mid-transfer without double-spending.
+
+See [Watchers & Mirror](../shared/watchers-mirror.md) for how the canonical
+state is mirrored to every bearer, and [Maps & Pay](maps-pay.md) for how a
+Nomad uses a bearer to find and pay for services.

+# Nomads
+
+A **Nomad** is a person using the OpenYield mesh through a **Reach** — the
+protocol-level identity a Holder uses to act on the mesh without a
+custodian, a gatekeeper, or a legacy financial position. The Nomad path
+is the entry path: a Nomad is a Holder who has a Reach and a [Stash](stash.md)
+and is on the way to earning the four Freeholder signals, but has not yet
+earned all four.
+
+## The Nomad path
+
+The pages here cover what a Nomad does day-to-day on the mesh:
+
+- [Reach](reach.md) — the identity; the first Freeholder signal (REQ-005).
+- [Stash](stash.md) — the personal [Storage Pool](../shared/storage-pools.md)
+  where a Nomad holds Bread (REQ-014).
+- [Bearers](bearers.md) — how a Nomad reaches the mesh (REQ-019): Internet,
+  OY-BLE, OY-WiFi-Direct, OY-LR live now; OY-SAT and OY-QR coming.
+- [Maps & Pay](maps-pay.md) — finding services and paying for them.
+- [Pacts](pacts.md) — the six contract shapes a Nomad encounters
+  (REQ-020): Pause, Ground, Stance, Cover, Stand Registry, Hub API.
+- [Standing](standing.md) — the Bayesian anti-gaming metric (REQ-006),
+  and why the mesh cannot be gamed.
+- [Window](window.md) — the delegation primitive (REQ-015): scope,
+  duration, rate-limit, audit-log, revoke.
+
+## Where a Nomad starts
+
+A Nomad starts with a Reach and a Stash — that is enough to begin. From
+there the bearers carry value to the Stash, Maps finds services, Pay and
+the Window let a Nomad use them without giving up custody, and Standing
+accrues as the Nomad acts. A Nomad who earns the 90-day Stash signal, the
+Standing threshold, the Capital signal, and the Vouch signal becomes a
+Freeholder (see the Freeholders section).
+
+## Shared concepts
+
+The Nomad path rests on the [shared concepts](../shared/index.md): the
+[Six Principles](../shared/six-principles.md), the [Bread scale](../shared/bread-scale.md),
+the [Storage Pools](../shared/storage-pools.md), the [Watchers & Mirror](../shared/watchers-mirror.md),
+and the [Lexicon](../shared/lexicon.md). The covenant is the same for
+every audience; the Nomad pages describe how it shows up in everyday use.

+# Maps & Pay
+
+**Maps** and **Pay** are the day-to-day Mesh Experience a Nomad uses on the
+mesh. Maps finds services; Pay settles them. Both run over the
+[bearers](bearers.md) and read the [Mirror](../shared/watchers-mirror.md) so a
+Nomad can find and pay for a service on a surveillance-resistant bearer
+without an internet connection to OY Chain.
+
+## Maps
+
+Maps is the directory of services a Nomad can reach. A service is anything
+a Partner or a Stand exposes to the mesh: a Care service, a SIM, a Vault,
+a Mailbox (preview of v0.3 P5 — see [Pacts](pacts.md) for the Hub API). Maps
+is sorted by geographic proximity (REQ-007): a Nomad physically closer to a
+service or its operator is shown that service first. There is no paid
+ranking; the order is proximity, not promotion.
+
+## Pay
+
+Pay is how a Nomad settles a service. A payment is a transfer of Bread
+from the Nomad's [Stash](stash.md) to the service operator's Stash, signed
+by the Nomad's [Reach](reach.md). The fee covenant floors and caps the fee;
+inside a Guild, a Hand-Pass is free at the protocol level (REQ-017). Pay
+runs over any bearer, first-to-deliver-wins.
+
+## Authorize, don't hand over
+
+For recurring services a Nomad does not re-sign every payment. Instead
+the Nomad opens a [Window](window.md) to the service: a scoped,
+time-limited, rate-limited, revocable capability that lets the service pull
+value from the Stash within bounds the Nomad set. The Window is audited;
+the Nomad can revoke it at any time. This is the self-service principle in
+practice: the Nomad delegates a capability, not custody.
+
+## Find, pay, verify
+
+A Nomad's loop is:
+
+1. **Find** a service on Maps.
+2. **Pay** once, or **authorize** a [Window](window.md) for recurring use.
+3. **Verify** the service against the Watcher attestations on the Mirror
+   (see [Watchers & Mirror](../shared/watchers-mirror.md)).
+
+See [Stash](stash.md) for where the Bread comes from, [Window](window.md)
+for the delegation primitive, and [Standing](standing.md) for how a
+service operator's history is measured.

docs/nomads/pacts.md

+# Pacts
+
+The **six Pacts** (REQ-020) are the contract shapes a Nomad encounters on
+the mesh. A Pact is a typed, mission-locked agreement between parties; the
+core terms of the Pause, Ground, and Stance Pacts are **non-amendable** —
+no Council can rewrite them after the fact. A Nomad mostly interacts with
+Pacts through [Maps & Pay](maps-pay.md) and the [Window](window.md)
+primitive, but it helps to know what each one is.
+
+## The six Pacts
+
+| Pact | What it does for a Nomad |
+|---|---|
+| **Pause** | A temporary hold. A Nomad can pause a recurring payment or a Window without voiding it; the Pause core terms are non-amendable. |
+| **Ground** | A baseline obligation the mesh enforces by default — the "ground rules" between a Nomad and a service operator. Non-amendable. |
+| **Stance** | A stated position a party commits to (e.g., a service operator's Stance on jurisdiction-light operation). Non-amendable. |
+| **Cover** | A flat commitment a Stand or a Partner offers to cover a Nomad against a defined failure; a Nomad reads Cover when choosing a service. |
+| **Stand Registry** | The registry of the nine [Stand](../shared/storage-pools.md) types (Household, Crew, Entity, Co-op, Circle, Trust, Foundation, Confederation, Shadow) a Nomad can join. |
+| **Hub API** | The B2B backbone (preview of v0.3 P5) — the Hub Pact exposes custody, a lending primitive, and compliance to service operators. A Nomad sees the Hub through Maps, not directly. |
+
+## What a Nomad actually does with Pacts
+
+A Nomad does not draft Pacts by hand. The flow is:
+
+1. **Find** a service on [Maps & Pay](maps-pay.md).
+2. The service's terms are backed by one or more Pacts (e.g., a recurring
+   payment is a Pause-able Window; a Stand's service is registered in the
+   Stand Registry).
+3. The Nomad **authorizes** a [Window](window.md) scoped to those terms.
+
+## Mission Lock
+
+The Pause, Ground, and Stance core terms are mission-locked: a `const`
+flag in the Pact module marks them non-amendable, and an invariant test
+asserts that flag can never flip. A Nomad can rely on the ground rules
+not changing. See [Six Principles](../shared/six-principles.md) for the
+mission-lock covenant.
+
+See [Window](window.md) for the delegation primitive the Pacts are
+delivered through, and [Standing](standing.md) for how a service
+operator's history is measured.

+# Reach
+
+A **Nomad** is a person using the OpenYield mesh through a **Reach** — the
+protocol-level identity that lets a Holder act on the mesh without a
+custodian, a gatekeeper, or a legacy financial position. The Reach is the
+first of the four Freeholder signals (REQ-005), and it is the baseline every
+Nomad starts from: a Nomad is a Holder who has a Reach and a Stash but has not
+yet earned all four Freeholder signals.
+
+## What a Reach is
+
+A Reach is an identity, not a custodial position. It is the by-ID-string a
+Holder uses to receive value, open a [Window](window.md), join a Stand, or
+pay for a service. The protocol does not require KYC at the protocol layer;
+the Reach is the unit of self-service (see [Six
+Principles](../shared/six-principles.md)).
+
+## How a Nomad starts
+
+A Nomad starts with two things:
+
+1. **A Reach** — the identity.
+2. **A [Stash](stash.md)** — the personal [Storage Pool](../shared/storage-pools.md)
+   where the Holder holds Bread.
+
+That pair is enough to begin. From there a Nomad can use the [bearers](bearers.md)
+to reach the mesh, find services on [Maps & Pay](maps-pay.md), authorize a
+[Window](window.md) to a partner, and accrue [Standing](standing.md).
+
+## Geographic proximity
+
+The mesh processes actions first-come, first-served with a
+geographic-proximity preference (REQ-007) — a Nomad physically closer to a
+service or a Stand's region is served first. The Reach is how the mesh
+identifies the Nomad for that ordering; there is no separate tier to buy into.
+
+## The four Freeholder signals
+
+The Reach is the first Freeholder signal. The four signals (REQ-005) are
+earned over time: the 90-day [Stash](stash.md) signal, the Standing
+threshold, the Capital signal, and the Vouch signal. A Nomad who earns all
+four becomes a Freeholder (see the Freeholders section). The pages here cover
+the Nomad path — everything up to that point.
+
+See [Stash](stash.md) for the Storage Pool a Reach holds Bread in,
+[Bearers](bearers.md) for how to reach the mesh, and
+[Standing](standing.md) for the anti-gaming metric that accrues as a Nomad
+acts on the mesh.

+# Standing
+
+**Standing** (REQ-006) is a Holder's measured history on the mesh. It is
+the anti-gaming metric: a Bayesian score with time-decay, diversity
+weighting, and voucher-weighting, minus slashes for bad behavior. For a
+Nomad, the headline is that the mesh **cannot be gamed** — Standing
+rewards real production and resists the obvious attacks (volume spam,
+self-dealing, fake vouches).
+
+## What Standing is, in plain language
+
+Standing is not a count of transactions. It is a Bayesian score: the mesh
+starts with a prior, updates it from each observed action, and decays
+old evidence so a Holder cannot rest on a burst of activity from years
+ago. Diversity weighting means a Nomad who acts across many services,
+many Stands, and many bearers accrues more Standing than a Nomad who
+repeats the same action with the same counterparty. Voucher-weighting
+means a vouch from a Holder with high Standing counts for more.
+
+## Why it matters to a Nomad
+
+A Nomad mostly reads Standing, not computes it. Two places it shows up:
+
+- **Choosing a service.** Maps shows a service operator's Standing so a
+  Nomad can pick an operator with a real history over a freshly-spun-up
+  alternative (see [Maps & Pay](maps-pay.md)).
+- **The Freeholder path.** Earning a Standing threshold in 3 categories
+  is one of the four Freeholder signals (REQ-005). A Nomad who accrues
+  Standing over time is on the path to becoming a Freeholder.
+
+## What Standing is not
+
+Standing is not a custodial position, a tier you buy, or a reputation
+score you can farm. It is not legacy custodial history. The
+Bayesian + time-decay + diversity design is exactly what makes it hard to
+game: there is no single input a Holder can pump.
+
+## The math, deferred
+
+The full Bayesian formula (priors, decay rates, diversity sub-tables,
+slash conditions) is documented in the Freeholders section — a Nomad does
+not need the math to use the mesh. See
+[Six Principles](../shared/six-principles.md) for the covenant Standing
+enforces, and [Reach](reach.md) for the identity a Standing accrues to.

+# Stash
+
+A **Stash** is a Holder's personal [Storage Pool](../shared/storage-pools.md)
+(REQ-014). It is the place a Nomad holds Bread, and it is the second thing a
+Nomad needs after a [Reach](reach.md) to begin. The Stash is the unit of
+self-service: the Holder owns it, controls it, and can delegate a scoped,
+time-limited, revocable [Window](window.md) to a partner or a service
+without giving up custody.
+
+## What a Stash is
+
+The Stash is the Holder-level layer of the three Storage Pools (Stash,
+Vault, Root-Pool). It is a storage layer, not a custodial position: the
+protocol holds the canonical state that records who owns what; the Holder
+holds the value. There is no custodian between a Nomad and their Stash.
+
+## How a Nomad uses a Stash
+
+A Nomad moves Bread into a Stash through the [bearers](bearers.md) — a
+Holder on a surveillance-resistant bearer can receive value without an
+internet connection to OY Chain. From the Stash a Nomad can:
+
+- **Hold** Bread (the unit of value — see [Bread scale](../shared/bread-scale.md)).
+- **Pass** value to another Reach (the Hand-Pass, free at the protocol
+  level inside a Guild).
+- **Pay** for a service via [Maps & Pay](maps-pay.md).
+- **Authorize** a [Window](window.md) so a partner or service can read the
+  Stash within bounds the Holder set.
+
+## The 90-day Freeholder signal
+
+Holding a Stash continuously for 90 days is the first of the four
+Freeholder signals (REQ-005). The Stash does not need to hold a large
+amount — the signal is about continuity, not size. A Nomad who keeps a
+Stash for 90 days and earns the other three signals (Standing, Capital,
+Vouch) becomes a Freeholder.
+
+## Delegation, not custody
+
+The Stash stays the Holder's. When a Nomad opens a Window to a service,
+the service gets a scoped capability (e.g., "read Stash balance for the
+next hour", "spend up to N Grain on this service this week") — it does not
+get custody. The Window is revocable, rate-limited, and audited. See
+[Window](window.md) for the primitive.
+
+See [Storage Pools](../shared/storage-pools.md) for the full three-pool
+model, and [Bearers](bearers.md) for how value reaches a Stash over a
+surveillance-resistant bearer.

+# Window
+
+A **Window** (REQ-015) is the primitive a Nomad uses to delegate a
+capability without delegating custody. It is scoped, time-limited,
+rate-limited, audited, and revocable. A Nomad opens a Window so a partner
+or a service can act on the Nomad's [Stash](stash.md) within bounds the
+Nomad set — the partner never gets custody, and the Nomad can close the
+Window at any time.
+
+## The five parts of a Window
+
+| Part | What it bounds |
+|---|---|
+| **Scope** | what the grantee can do (e.g., read Stash balance, spend up to N Grain on a specific service). |
+| **Duration** | when the Window starts and ends (a start time and an end time). |
+| **Rate limit** | how many actions per duration window (e.g., at most 10 reads per hour). |
+| **Audit log** | an append-only log of every action the grantee took under the Window. |
+| **Revoke** | the Nomad can revoke the Window at any time; revoke after expiry is a no-op. |
+
+## Why a Nomad opens one
+
+A Nomad opens a Window for the same reason a Nomad uses [Maps & Pay](maps-pay.md):
+to let a service do something on the Nomad's behalf without handing over
+the Stash. Common examples:
+
+- A recurring service (e.g., a Care service) pulls a capped amount of
+  Bread from the Stash each week, within a rate limit the Nomad set.
+- A partner reads the Stash balance for a compliance check, scoped to
+  read-only, time-limited to one hour.
+- A Stand operator processes a Pass-Act on the Nomad's behalf inside a
+  scoped, audited Window.
+
+## Lifecycle
+
+A Window moves through a fixed lifecycle: **Open → Active → Revoked** or
+**Expired**. A Nomad can revoke at any point; revoking after expiry is a
+no-op (idempotent). The lifecycle is mission-locked: a partner cannot
+extend a Window past its end time — the Nomad must open a new one.
+
+## Self-service, by design
+
+The Window is the self-service principle in code. The protocol records
+the Window on OY Chain; the partner holds only the capability, never the
+value. See [Six Principles](../shared/six-principles.md) for the covenant,
+and [Pacts](pacts.md) for the contract shapes delivered through Windows.

+# Bread scale
+
+The unit of value in OpenYield is **Bread** (REQ-013). Bread is scaled in 11
+tiers, each 1,000× the previous, so a Holder can reason about a Crumb and a
+Granary in the same mental model:
+
+| Tier | Name | Multiple |
+|---|---|---|
+| 1 | **Grain** | 1 |
+| 2 | **Crumb** | 1,000 Grain |
+| 3 | **Bread** | 1,000 Crumb |
+| 4 | **Loaf** | 1,000 Bread |
+| 5 | **Batch** | 1,000 Loaf |
+| 6 | **Cake** | 1,000 Batch |
+| 7 | **Bakery** | 1,000 Cake |
+| 8 | **Granary** | 1,000 Bakery |
+| 9 | **Mill** | 1,000 Granary |
+| 10 | **Harvest** | 1,000 Mill |
+| 11 | **Earth** | 1,000 Harvest |
+
+## Why 11 tiers
+
+The 11-tier scale gives the mesh a single unit for everything from a
+1-Grain internal minimum (the Fee Covenant floor) to the Earth-tier totals
+held in the Root-Pool. There is no separate "small unit" and "large unit":
+the Bread scale is the unit. The 1-Grain minimum prevents dust games; the
+tier names keep human-readable values at every scale.
+
+## Where Bread lives
+
+Bread is held in the three [Storage Pools](storage-pools.md): the Stash
+(Holder-level), the Vault (Stand-level), and the Root-Pool (treasury). The
+Watchers attest to the state of the pools daily; the Mirror mirrors the
+canonical state to the bearers. See [Watchers & Mirror](watchers-mirror.md)
+for the attestation layer.

+# Lexicon
+
+OpenYield bans 10 financial terms as standalone words (REQ-012). The firewall
+scans every Go file under `x/` and every Markdown file under `README.md` +
+`docs/`, and fails the build on any standalone occurrence. This page documents
+**why** the terms are banned and **what to say instead** — the replacements,
+not the banned literals.
+
+## Why a lexicon
+
+The words a legacy financial institution uses carry the shapes of that
+institution: custodial positions, jurisdiction-bound units, and
+speculation-language. OpenYield is a jurisdiction-light, public-good mesh for
+real production; using the old words would import the old shapes. The
+lexicon firewall keeps the mesh's language aligned with its covenant. The
+firewall is enforced in code by two sibling Go tests
+(`lexicon_meta_test.go` for `x/**/*.go`;
+`lexicon_meta_docs/lexicon_meta_docs_test.go` for `README.md` +
+`docs/**/*.md`), both using `lexicon.FindBannedTerm` (word-boundary,
+case-insensitive). Word-boundary matching means "OpenYield" is safe — the
+firewall bans standalone words, not substrings.
+
+## The 10 banned terms and their safe replacements
+
+The firewall bans 10 standalone words. This page does not write the banned
+words as literals (the firewall scans this page); it describes them by the
+concept each belongs to, and gives the safe replacement.
+
+### 1. The custodial-position word
+
+A legacy institution holds your value in a custodial position. OpenYield
+does not: a Holder owns their **Stash**, a Stand owns its **Vault**, the mesh
+owns the **Root-Pool**. The Holder's identity is a **Reach**, and the Holder
+themselves is a **Holder** — never the banned custodial-position word.
+
+- Banned: the word for a custodial position.
+- Safe: **Holder**, **Reach**, **Stash**, **Vault**, **Root-Pool**.
+
+### 2. The legacy-institution word
+
+The legacy financial institution itself is banned as a concept. OpenYield is
+a **mesh**, a **public good**, a **protocol** — not that word.
+
+- Banned: the word for a legacy financial institution.
+- Safe: **mesh**, **protocol**, **public good**.
+
+### 3. The place-value word
+
+The word for a place to hold value under custody is banned. Use the
+**Stash** (Holder-level), the **Vault** (Stand-level), or the **Root-Pool**
+(treasury).
+
+- Banned: the word for a place value is held.
+- Safe: **Stash**, **Vault**, **Root-Pool**, **Storage Pools**.
+
+### 4. The put-in word
+
+The verb for putting value into a custodial position is banned. Use **hold**,
+**store**, **move**, or **transfer**.
+
+- Banned: the verb for placing value under custody.
+- Safe: **hold**, **store**, **move**, **transfer**, **Pass-Act**.
+
+### 5. The passive-value word
+
+The word for value earned passively on a custodial position is banned. For
+bonds, use **coupon**. For the mesh's metric, use **real production** or
+**real return**.
+
+- Banned: the word for passive value on a custodial position.
+- Safe: **coupon**, **real production**, **real return**.
+
+### 6. The standalone metric word
+
+The standalone word for a return metric is banned (it is the same concept as
+#5 in verb form). Use **real production**, **real return**, or **coupon**
+(for bonds). "OpenYield" is safe — word-boundary matching does not flag the
+banned term inside an identifier.
+
+- Banned: the standalone return-metric word.
+- Safe: **real production**, **real return**, **coupon**. **OpenYield** is safe.
+
+### 7. The medium-of-exchange word
+
+The word for a national medium of exchange is banned. The mesh's unit is
+**Bread** (see [Bread scale](bread-scale.md)). For a foreign-exchange pair,
+use **Forex** (allowed) with **base-asset** / **quote-asset** labels, or
+**Bread / Asset**.
+
+- Banned: the word for a national medium of exchange.
+- Safe: **Bread**, **asset**, **Forex**, **base-asset**, **quote-asset**.
+
+### 8. The first national-unit word
+
+The word for the first major national unit is banned. Use **Bread** or
+opaque chain names (e.g., "Polygon", "OY-Chain").
+
+- Banned: the first national-unit word.
+- Safe: **Bread**, **asset**, chain names.
+
+### 9. The second national-unit word
+
+The word for the second major national unit is banned (the firewall bans it
+as a standalone word; "european" is safe by word-boundary). Use **Bread** or
+opaque chain names.
+
+- Banned: the second national-unit word.
+- Safe: **Bread**, **asset**, chain names. **European** is safe (word-boundary).
+
+### 10. The set-aside word
+
+The word for value set aside under custody is banned. Use **Stash**,
+**Vault**, or **Root-Pool**.
+
+- Banned: the word for value set aside.
+- Safe: **Stash**, **Vault**, **Root-Pool**.
+
+### 11. The holder-of-value word
+
+The word for the person who holds value under custody at a legacy
+institution is banned. Use **Holder**, **Freeholder**, or **Nomad**.
+
+- Banned: the word for a custodial-position holder.
+- Safe: **Holder**, **Freeholder**, **Nomad**, **Reach**.
+
+> **Note**: the firewall bans 10 standalone words; this page lists 11
+> replacements because two of the banned words (the passive-value word and
+> the standalone metric word) share a concept and get the same replacement
+> family (**coupon** / **real production** / **real return**).
+
+## How the firewall works
+
+The firewall uses `lexicon.FindBannedTerm` — a word-boundary, case-insensitive
+regex match — so:
+
+- "OpenYield" is **safe**: the standalone banned term inside an identifier
+  does not match (word-boundary).
+- "european" is **safe**: the standalone national-unit word inside a larger
+  word does not match.
+- The standalone banned word in prose **is** matched and fails the build.
+
+The firewall's own source (`lexicon/lexicon.go`) assembles the banned terms
+at runtime from two-character fragments, so the firewall's own code does not
+contain any banned term as a literal substring. The two sibling meta-tests
+(`lexicon_meta_test.go` and `lexicon_meta_docs/lexicon_meta_docs_test.go`)
+each include a self-test table that verifies detection of all 10 banned
+terms from the single source `lexicon.BannedTerms()` (G-014 drift
+prevention).

+# Six Principles
+
+The Six Principles are the immutable covenant of OpenYield (REQ-001). They
+are **Mission-locked**: no Council can amend them, and the fee covenant is
+locked alongside them. The mesh exists to hold real production, not
+speculation; everything else follows from that.
+
+## 1. Real value
+
+The mesh holds **real production**. The Bread unit is the unit of real value
+held in the Storage Pools; the bond market caps coupons so the mesh cannot
+become a speculation engine. "Real return" is the metric, not a nominal rate.
+
+## 2. Sustainability
+
+Fees are floored and capped. The fee covenant fixes a ceiling and a floor
+(see the Fee Covenant module), and the 1-Grain internal minimum prevents dust
+games. The protocol cannot drain its users, and it cannot starve its
+Watchers.
+
+## 3. Mission-lock
+
+The Six Principles and the fee covenant are immutable. No Council — Mesh,
+Guild, or Stand — can amend them. Mission Lock is a `const` in the council
+module, and an invariant test asserts it can never be set to amendable. The
+coupon cap on bonds is a mission-locked ceiling, not a parameter a Council
+can tune.
+
+## 4. Openness
+
+Anyone may join. The mesh is a public good. A Holder needs only a Reach (an
+identity) and a Stash (a storage pool) to begin; there is no gatekeeper and
+no custodian.
+
+## 5. Ownership
+
+Holders own their Stash and their Reach. Custody is theirs: the Stash is the
+Holder-level storage pool, the Vault is the Stand-level pool, and the
+Root-Pool is the treasury. The protocol does not custody user value; it
+holds the canonical state that records who owns what.
+
+## 6. Self-service
+
+A Holder can act without a custodian. The Window primitive lets a Holder
+delegate a scope-bounded, time-limited, revocable capability to a partner or
+a service; the bearers (OY-LR, OY-BLE, OY-WiFi-Direct, OY-SAT, OY-QR) let a
+Holder reach the mesh without a phone plan or a custodial on-ramp. The mesh
+is jurisdiction-light by design.
+

+See the [Vision](vision.md) for the covenant in brief, or the
+[Lexicon](lexicon.md) for why the docs say "real production" and "Holder"
+rather than the words a legacy financial institution would use.

+# Storage Pools
+
+OpenYield has three Storage Pools (REQ-014). Each is a layer of custody
+responsibility, and none of them is a custodial position — the protocol holds
+the canonical state that records who owns what; the Holder, the Stand, and
+the mesh treasury each hold their own pool.
+
+| Pool | Level | Held by | Purpose |
+|---|---|---|---|
+| **Stash** | Holder | a single Holder | the personal storage pool; the unit of self-service |
+| **Vault** | Stand | a Stand (a governed group) | the Stand-level pool; the unit of shared ownership |
+| **Root-Pool** | Mesh | the mesh treasury | the canonical treasury; the unit of the public good |
+
+## The Stash
+
+The Stash is the Holder-level storage pool. A Holder needs only a Reach (an
+identity) and a Stash to begin. The Stash is the unit of self-service: the
+Holder owns it, controls it, and can delegate a scoped, time-limited,
+revocable Window to a partner or a service without giving up custody. See
+[Watchers & Mirror](watchers-mirror.md) for the attestation layer that
+records Stash state.
+
+## The Vault
+
+The Vault is the Stand-level storage pool. A Stand is a governed group
+(one of the nine Stand types: Household, Crew, Entity, Co-op, Circle,
+Trust, Foundation, Confederation, Shadow) that holds a Vault in common. The
+Stand's decision policy (threshold or weighted, mirroring the Cosmos SDK
+`x/group` shape) governs how the Vault is used. See the Freeholders section
+for Stands & Guilds.
+
+## The Root-Pool
+
+The Root-Pool is the mesh treasury. It holds the canonical state of the
+Bread unit, the Watcher bonds, and the Root Basket. The Root-Pool is the
+unit of the public good: the Watchers attest to its state daily, and the
+Mirror mirrors it to the bearers so a Holder can verify the mesh's real
+return without trusting a single custodian.
+
+## Custody, not custody
+
+The three pools are storage layers, not custodial positions. The protocol
+does not custody user value; it holds the canonical state that records who
+owns what. A Holder's Stash is theirs; a Stand's Vault is the Stand's; the
+Root-Pool is the mesh's. The Window primitive lets a Holder delegate a
+capability without delegating custody. See the [Lexicon](lexicon.md) for
+why the docs say "Stash", "Vault", and "Root-Pool" rather than the words a
+legacy financial institution would use.

+# Vision
+
+OpenYield is a jurisdiction-light, public-good mesh for **real production**.
+The vision is a covenant, not a product: the mesh holds real value, the Six
+Principles are immutable, and the protocol cannot become a custodial
+platform. This page is the brief overview; the full vision source lives in
+`.ciagent/oy/PROJECT.md`.
+
+## The covenant
+
+OpenYield exists to hold **real production** — the real return of real work,
+held in the Bread unit, in the three Storage Pools, attested by the Watchers,
+mirrored by the Mirror. The covenant is anti-greed by construction:
+
+- **Mission Lock** fixes the Six Principles and the fee covenant. No Council
+  — Mesh, Guild, or Stand — can amend them. The coupon cap on bonds is a
+  mission-locked ceiling, not a parameter.
+- **Jurisdiction-light** — the bearers (OY-LR, OY-BLE, OY-WiFi-Direct, OY-SAT,
+  OY-QR) let a Holder reach the mesh without a phone plan or a custodial
+  on-ramp. A Holder needs only a Reach and a Stash to begin.
+- **Public good** — the mesh is open to all. The Watchers attest daily; the
+  Mirror mirrors the state; anyone can verify the mesh's real return without
+  trusting a single custodian.
+
+## The layers
+
+1. **OY Chain** (Layer 1) — the canonical state: the Bread unit, the
+   Storage Pools, Standing, Watcher attestations, the Pact / Council /
+   Partner surface.
+2. **Satellites** (Layer 2) — wrapped Bread propagates to satellite chains
+   (Polygon active; Base, Arbitrum, Optimism, Solana as enum placeholders)
+   via IBC.
+3. **Bearers** — the surveillance-resistant transport layer: OY-LR (LoRa,
+   long-range), OY-BLE (Bluetooth), OY-WiFi-Direct, OY-SAT (satellite),
+   OY-QR (paper / QR code). The Mirror mirrors canonical state to them.
+4. **Exits** — the Layer 3 exit layer: Holder-initiated DEX swaps and
+   off-mesh service exits, with bridge routes for cross-chain exits.
+
+## The actors
+
+- **Holders** (Nomads) — the everyday participants, each with a Reach and a
+  Stash.
+- **Freeholders** — the active participants who run Stands, Guilds, and
+  Councils.
+- **Partners** — the four-tier spectrum (Op, MasterOp, Pier, Anchor) that
+  processes Pass-Acts and provides credentials and institutional backing.
+- **Watchers** — the 9 attesters with 6-of-9 quorum and 100,000 Bread bonds.
+
+## The units
+
+- **Bread** — the unit of real value (see [Bread scale](bread-scale.md)).
+- **Standing** — the reputation layer (the four signals, Bayesian Standing).
+- **Voice** — the governance input (multi-source: Stash, Standing, Vouch,
+  Freeholder, Guild).
+- **Coupon** — the bond-market term (capped at 8% / floored at 0%, mission-locked).
+
+## Where to go next
+
+- [Six Principles](six-principles.md) — the immutable covenant.
+- [Storage Pools](storage-pools.md) — the three pools.
+- [Watchers & Mirror](watchers-mirror.md) — the attestation layer.
+- [Lexicon](lexicon.md) — why the docs say "real production" and "Holder".

+# Watchers & Mirror
+
+OpenYield is attested by **9 Watchers** with a **6-of-9 quorum** (REQ-004).
+The Watchers make daily attestations to the canonical state, and each posts
+a 100,000 Bread bond. The **Mirror** mirrors the canonical state to the
+bearers so a Holder can verify the mesh's state without trusting a single
+Watcher.
+
+## The 9 Watchers
+
+The Watchers are the attestation layer of the mesh. There are exactly 9, and
+the quorum is 6-of-9: any 6 Watchers can attest to a state transition, but no
+5 can. Each Watcher posts a 100,000 Bread bond, which is at risk if the
+Watcher attests to a false state. The 9/6 split is a mission-locked
+parameter — no Council can lower the quorum or the bond.
+
+## Daily attestations
+
+The Watchers attest to the state of the three [Storage Pools](storage-pools.md)
+daily: the Stash totals, the Vault totals, and the Root-Pool. The
+attestation is a signed statement that the canonical state recorded by OY
+Chain matches the state the Watcher observed. A Holder who wants to verify
+the mesh's real return can read the attestations and check that the
+Watchers agree.
+
+## The Mirror
+
+The Mirror mirrors the canonical state to the bearers (OY-LR, OY-BLE,
+OY-WiFi-Direct, OY-SAT, OY-QR). A Holder on a surveillance-resistant bearer
+can read the mirrored state without an internet connection to OY Chain; the
+Mirror is the read-side of the bearer layer. The Mirror is read-only: it
+mirrors state, it does not author it. Authoritative state lives on OY Chain
+and is attested by the Watchers.
+
+## Why 6-of-9
+
+The 9/6 split is a balance: 9 is large enough that no single adversary can
+easily capture a quorum, and 6 is large enough that no small cabal can
+attest to a false state. The 100,000 Bread bond per Watcher makes
+capturing a quorum expensive. The split is locked by Mission Lock — no
+Council can change it. See [Six Principles](six-principles.md) for the
+mission-lock covenant.

+// x/council depends on (G-003 firewall — ibc-go expected-keepers convention).
+//
+// The Council Proposal lifecycle (REQ-039, D-060) depends on TWO cross-module
+// keepers:
+//
+//  1. x/watcher (WatcherKeeper) — the Veto authz for the Vote handler. The
+//     VoteOption.Veto is the Watcher-only block signal (anti-greed, vision
+//     §19). The handler consults the WatcherKeeper shim to assert the
+//     voter-reach is a Watcher BEFORE recording a Veto; a non-Watcher
+//     casting Veto is REJECTED at the handler. The handler does NOT consult
+//     the quorum on the Veto payload (unlike x/partner's
+//     IsQuorumSigned-on-payload pattern); the Veto quorum is a TALLY-time
+//     check (NoWithVeto >= WatcherVetoQuorum in the Params, default 6 per
+//     D-065/A-574), NOT a VOTE-time check. The single-Veto-no-block rule
+//     (anti-greed) means a single Veto is recorded but does NOT block; the
+//     quorum (default 6) must be met at tally to FAIL the proposal.
+//
+//  2. x/stand (StandKeeper) — the proposal-target validation for a
+//     Stand-kind Proposal. The handler asserts the council-id references a
+//     Stand Council whose stand-id-ref references a real Stand BEFORE
+//     creating the Proposal. The interface is the by-ID-string boundary
+//     (G-003 — no struct import of x/stand/types).
+//
+//  3. x/guild (GuildKeeper) — the proposal-target validation for a
+//     Guild-kind Proposal (mirrors StandKeeper). The handler asserts the
+//     council-id references a Guild Council whose guild-id-ref references
+//     a real Guild.
+//
+// All three dependencies are expressed as INTERFACES defined HERE (in
+// x/council/types), NOT as struct imports of x/watcher/types,
+// x/stand/types, or x/guild/types. The concrete keepers satisfy these
+// interfaces structurally; the handler depends on the interface, preserving
+// G-003's intent (no cross-module struct coupling, no import cycles).
+//
+// Test-only cross-package imports (the G-003 test exemption) remain
+// exempt: a simtest may import both x/council/keeper and x/watcher/keeper
+// (or x/stand/keeper, x/guild/keeper) to wire the expected-keeper shims in
+// a test setup.
+
+// WatcherKeeper is the expected-keeper interface for x/watcher (G-003).
+// The council Vote handler calls it for:
+//   - Vote (Veto authz): a Vote with Option == VoteOptionVeto must come
+//     from a Watcher. The handler consults the WatcherKeeper shim to

+//     non-Watcher casting Veto is REJECTED at the handler. The Veto
+//     quorum (default 6 per D-065/A-574) is a TALLY-time check, NOT a

+//     quorum must be met at tally to FAIL the proposal.
