+## 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).
+
+---
+
+## v0.7 Architecture (Fraternal Groups Foundation)
+
+This section appends the v0.7 component map. v0.7 introduces a NEW module
+`x/cover` (D-084, D-039 precedent) and extends 4 existing modules. No
+breaking schema changes to locked-const firewall; G-003 production firewall
+intact; G-006 go.mod unchanged (`x/cover` uses existing cosmos-sdk substrate).
+
+### v0.7 Component Index (new + extended modules)
+
+| # | Component | Vision § | v0.7 Module | New/Ext | Phase | v0.7 Runtime Depth |
+|---|---|---|---|---|---|---|
+| 8 | Cover Pool Factory (Pact #4 Cover graduated) | §16 | `x/cover` | New | P1-P5 | CoverPool + CoverCharter + CoverCall + CoverFeeTag structs + Factory keeper + Anti-Crowding-Out firewall + Anti-Capture Bill of Rights (13 rights) + Cover Claims Voucher role + Pool governance hybrid + category staging; simtest-grade runtime (D-020) |
+| 8 | Mutual Aid Bond (Pact #5 Bonds extended) | §17 | `x/bond` | Extended | P4 | MAB struct (anonymous embed of Bond) + CouponDenom enum (CoverCall/MutualAidCredit/Bread-rejected) + 3× annual surplus ceiling + tagged streaming use-of-proceeds (D-080); simtest |
+| 10 | Chapter Federation (Orgs extended) | §12 | `x/guild` | Extended | P3 | ParentGuildID + IsChapter + SecessionTermsHash + GoodStandingLiens fields on Guild + SecessionTerms struct + cooling consts (21d/14d) + Household simplified + Confederation Voice; simtest |
+| 6 | Shadow vouch weight + Cover Claims Voucher slash | §9.1, §9.4 | `x/standing` | Extended | P4 | ShadowVouchWeightMultiplier=0.5 const + IsShadow field on Vouch + SlashReasonFraudulentCoverCall const; simtest |
+| 10 | Stand→Pier boundary + Household/Confederation keeper logic | §11, §13 | `x/stand` | Extended | P3, P5 | StandPierEscalationAnnualPassVolumeCents const + Household one-tap exit + Confederation Voice aggregation (switch on existing StandType, no struct change); simtest |
+| 8 | Pact Cover cross-reference (no change) | §16 | `x/pact` | Unchanged | — | PactCover enum value stays as cross-reference (D-084, mirrors PactHubAPI ↔ x/hub); ExecuteCover() stub stays |
+
+> The Cover Pool Factory is Pact #4 (Cover) per REQ-020/D-027. v0.2 stubbed
+> it as a PactType enum value inside `x/pact`; v0.7 promotes it to its own
+> `x/cover` module for the Factory + Charter + Bill of Rights + Voucher
+> runtime (D-084). The `x/pact` PactCover enum value stays as a
+> cross-reference; `x/cover` owns the runtime surface. This mirrors the
+> D-039 precedent (`x/hub` split from `x/pact`'s PactHubAPI in v0.3).
+
+### v0.7 Cross-Component Dependencies (within v0.7)
+
+Per the G-003 invariant (by-ID-string inter-module references; no struct
+imports across `x/<module>/types`), v0.7 components reference each other and
+the v0.2-v0.6 baseline by ID string only. The dependency edges that affect
+v0.7 phase ordering:
+
+```
+x/cover   ──(StandingKeeper shim)──►  x/standing   (P1: gate query; G-003 expected_keepers.go)
+x/cover   ──(WatcherKeeper shim)──►  x/watcher    (P1: attestation pipeline; P4: MAB release witness)
+x/cover   ──(BondKeeper shim)──►    x/bond       (P4: MAB issuance ceiling query)
+x/bond    ──(CoverKeeper shim)──►   x/cover      (P4: MAB MsgDebitMABProceeds queries CoverKeeper.GetPoolReserveAccount; D-089(2) reverse edge — no import cycle, interface only)
+x/bond    ──(Stand by id)──►        x/stand      (v0.2 baseline; MAB issuer-stand-id, unchanged)
+x/guild   ──(Stand by id)──►        x/stand      (v0.2 baseline; Guild StandAffiliationID, unchanged)
+x/guild   ──(Cover Pool by id)──►   x/cover      (P3: Chapter Federation liens reference Cover Pool covenants)
+x/cover   ──(StillKeeper stub)──►   x/still      (P1: auto-pause on below-floor; P4: auto-Still on MAB misuse; D-089(1) simtest-local stub, NOT a real x/still keeper — x/still is NOT extended this milestone)
+x/cover   ──(PactCover by id)──►    x/pact       (cross-reference only; no struct import)
+```
+
+**Phase-ordering implication (informs D-082):** `x/cover` P1 lands the
+Factory + firewall + locked floors + gates + tagging first (firewall-first
+pattern). P2 extends `x/cover` with Charter + governance + staging. P3
+extends `x/guild` (Chapter Federation depends on Cover Pool existing for
+lien/covenant references). P4 extends `x/bond` (MAB depends on Cover Pool
+reserve existing for use-of-proceeds) + `x/standing` (Shadow vouch + Voucher
+slash). P5 lands the Anti-Capture Bill (cross-cutting; constrains all prior
+surfaces) + secession cooling + Pier boundary. Confidence 0.82.
+
+### v0.7 Interface Contracts (6 cross-component — extended this milestone)
+
+The six cross-component interfaces are EXTENDED in v0.7:
+
+- **Standing API** — `x/cover` Factory queries Standing via expected-keeper
+  shim (StandingKeeper.GetStandingBucket) for the Cover Pool Standing gate
+  (REQ-049, D-077). By-ID-string at type level (G-003).
+- **Watcher Attestation Interface** — `x/cover` Factory + MAB release invoke
+  Watcher attestation via WatcherKeeper shim. Cover-Charter signed by Pool
+  Host + witnessed by Watcher (REQ-052). MAB proceeds release requires
+  Watcher quorum (D-080).
+- **Window Lifecycle Interface** — unchanged in v0.7 (Cover-Charter
+  amendments cooling uses the existing Window Duration semantics; secession
+  cooling is a separate const-based mechanism, not a Window).
+- **Fee Covenant Interface** — unchanged in v0.7 (Cover-Fees are a separate
+  tagging surface, not a Fee-Covenant route; the Anti-Crowding-Out firewall
+  enforces the separation).
+- **Voice/Council Interface** — `x/cover` Pool governance hybrid (REQ-062)
+  = Pool Host + 3 elected Masons + Watcher observer. No Anchor seat (§5
+  Anchor no-Voice). MAB holders have NO Voice (REQ-063). Confederation Voice
+  (REQ-058) aggregates one-per-Stand.
+- **Forge/Fold** — unchanged in v0.7.
+
+### v0.7 Locked-Const Firewall Additions (GRILL-ratified D-086..D-090)
+
+Per oy-state §3 + GRILL D-087, v0.7 adds 12 new locked consts (all net-new, no amendments to existing consts):
+
+| Const | Value | Module | REQ |
+|-------|-------|--------|-----|
+| CoverReserveFloorAnnualContribX | 1.5 | x/cover | REQ-047 (locked) |
+| CoverReserveCeilingAnnualContribX | 2.5 | x/cover | REQ-048 (not locked) |

-| NO leftover execution phase branches | `git branch \| grep "oy/phase"` → only `oy/phase/05-final-review-ship` ✓ | PASS |
-
-`git branch | grep "oy/phase"` returns exactly one line: `* oy/phase/05-final-review-ship`. The execution phase branches `oy/phase/01-orgs-window-foundation`, `oy/phase/02-pacts-partners`, `oy/phase/03-councils-forex`, `oy/phase/04-bonds-bearers-l2` are all correctly deleted after their respective phase ships. Only the final-phase branch remains (as expected — it is the active phase).
-
-### 1.4 Commit Discipline — **PASS**
-
-**Every commit on the milestone branch has a `---ci---` block with `project: oy`:**
-
-All 5 commits (P0-P4) carry `---ci---` blocks. Verified `project: oy` present in each (see §1.1 table). Multi-project mode discipline observed.
-
-**Phase ship commits have `status: complete` + `requirements: covered`:**
-
-All 5 commits have `status: complete` ✓. All 5 have a `requirements:` block with a `covered:` list (see §1.1 table) ✓. P3 also honestly declares `partial: [REQ-009]` (Forex oracle is consumed by Piers — soft ordering note; REQ-009 is fully covered by P4's `x/satellite`). No phase falsely claims full coverage.
-
-**Task commits have `plan:`/`task:`/`status: execute`:**
-
-The milestone branch uses a **one-commit-per-phase** squash model (each `docs(PNN): complete ...` commit is the phase ship commit). There are no intermediate per-task commits on the milestone branch — per-task commits were made on the per-phase execution branches (`oy/phase/01-*`..`04-*`), then squashed into the single phase-ship commit on the milestone branch. This is a valid CIAgent ship pattern (vertical-slice integrity preserved at the phase granularity). The `---ci---` blocks correctly carry `phase: N`, `status: complete`, `phase_role: execution` (on P1-P4), and the covered REQ list. The final-phase branch (`oy/phase/05-final-review-ship`) is the active phase; its commit will carry `phase: 5`.

-## 2. Critical Issues Found (MUST fix before milestone ship)
-
-**Initial critical issue count: 2** — both from the P5-01-03 deliverable (REQ-coverage audit + ROADMAP tag-line reconciliation), which is part of the P5 must-haves but had NOT been executed at audit time (HEAD was still the P04 ship commit; P5 doc work was pending).
-
-### Critical-1: REQUIREMENTS.md status column NOT updated (P5-01-03 obligation)
-
-- **Spec**: PLANS.md P5-01-03 — "update REQUIREMENTS.md status column (Pending → Skeleton)" for all v0.2 REQs.
-- **Pre-fix state**: all 8 v0.2-scope REQs (REQ-009, REQ-011, REQ-015, REQ-016, REQ-017, REQ-018, REQ-020, REQ-021) still showed `Pending | Future`. Two v0.2 components beyond the REQ list (Bearers OY-LR/Beacon per D-029, Forex v1 per D-030) were not represented at all.
-- **Impact**: the milestone's own requirement-coverage audit deliverable was unmet. A reader of REQUIREMENTS.md would conclude v0.2 shipped nothing, contradicting the 5 phase-ship commits and the 10 new/extended packages in the codebase.
-- **Disposition**: FIXED in this final phase. Status column updated: all 8 v0.2 REQs → `Skeleton` with `v0.2/PN` phase tags; Bearers OY-LR/Beacon and Forex v1 added as explicit rows; v0.1 summary test count corrected to 53 (G-001); a v0.2 Milestone Summary block added documenting the 10 packages, locked-const invariants, coverage, tag chain, and the G-010 tag-line note.
-
-### Critical-2: ROADMAP.md tag-line reconciliation (G-010) NOT done; Phase 2 not marked complete
-
-- **Spec**: PLANS.md P5-01-03 + GRILL.md G-010 — "reconcile ROADMAP.md's v0.0.x → v0.1.x tag-line note so the milestone release (`v0.1.5`) is not confused with the v0.0.x pre-MVP line"; PLANS.md P5-02-01 — "update ROADMAP.md Phase 2 checkbox".
-- **Pre-fix state**: ROADMAP.md Phase 2 section had no skeleton-status note, no module mapping, no tag-line reconciliation note, and no completion marker. The v0.0.x (pre-MVP) vs v0.1.x (Mesh) patch-line distinction existed only implicitly (line 15 mentions a deferred "v0.1.0 MVP" tag, which collides with v0.2's P0 tag `v0.1.0` — exactly the confusion G-010 was raised to prevent).
-- **Impact**: a reader could confuse the v0.2 P0 tag `v0.1.0` with the ROADMAP's deferred "v0.1.0 MVP" tag (line 15), and could not see from ROADMAP.md that v0.2 had shipped any skeleton work.
-- **Disposition**: FIXED in this final phase. Phase 2 header marked `— v0.2 SKELETON COMPLETE`; the deliverable table extended with `v0.2 Skeleton Module` and `Phase` columns mapping each Year-2 deliverable to its shipped `x/<module>`; a G-010 tag-line reconciliation note added explicitly distinguishing the `v0.0.x` pre-MVP line (lines 4-13) from the `v0.1.x` Mesh line, listing the full tag chain `v0.1.0..v0.1.5`, and stating that `v0.1.5` is the milestone release (not the deferred MVP tag).
-
-**Post-fix verification**: `go test ./...` re-run after the doc edits — still GREEN (exit 0). The fixes are documentation-only in `.ciagent/oy/`; no source code under `x/` was touched (auditor is read-only w.r.t. source; the critical fixes are `.ciagent` doc updates, which is the P5-01-03 deliverable surface).
-
-**Remaining critical issue count after fixes: 0.**

-## 3. Non-Critical Observations (P1+ flags, not blocking)
-
-These are design-shape divergences in a single module's non-must-have lifecycle types, carried over from REVIEW.md §3. They do NOT block the milestone ship. They are flagged for post-hoc review by the orchestrator / a future v0.3 PLAN phase.
-
-### P1-1: Council module — Proposal/VoteOption lifecycle enums absent
-- **File**: `x/council/types/types.go` (entire file)
-- **Spec drift**: 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/VoteOption lifecycle.
-- **Must-have impact**: NONE. P3 must-haves (3 councils, Mission Lock, TallyResult x/gov shape, no veto) all met.
-- **Recommendation**: add `Proposal`/`ProposalStatus`/`VoteOption` in v0.3 when wiring the council keeper to a live governance runtime.
-- **Severity**: P1 (spec drift from deliverable text, not a must-have, not blocking).
-
-### P1-2: Council VoiceSource → SignalKind (4 sources, not 5)
-- **File**: `x/council/types/types.go` (`SignalKind` enum)
-- **Spec drift**: P3-01-01 deliverable specified `VoiceSource` (Stash/Standing/Vouch/Freeholder/Guild — 5 sources). Implemented: `SignalKind` (Stash/Standing/Vouch/Capital — 4 sources; Freeholder + Guild dropped, Capital added).
-- **Code rationale**: Freeholder is an eligibility property (upstream in `x/standing`), Guild is a council tier — neither is a voice signal. Capital is committed-capital (vision §9.1). Defensible design refinement, but diverges from deliverable text.
-- **Must-have impact**: NONE. P3 must-haves did not enumerate VoiceSource coverage.
-- **Recommendation**: confirm intended v0.2 shape, or restore 5-source `VoiceSource` for v0.3 wiring. The `SignalKindCount=4` locked-const test currently locks the 4-source shape; changing it is a deliberate locked-const update.
-- **Severity**: P1 (design-choice divergence, tested and self-consistent, not blocking).
-
-### P2 (nit): Bearers ValidateGenesis remains a no-op
-- **File**: `x/bearers/types/types.go:108`
-- **Note**: CORRECT per spec — P4-02-01 said "DefaultParams/GenesisState unchanged" (bearers is an EXTENSION, not a new module; the A-212 ValidateGenesis upgrade was scoped to NEW modules only). Recording for completeness, not a defect. No action.
-
-### Observation: CHECKPOINT.json `phase: 4` (not 5)
-- **Note**: CHECKPOINT.json reflects the last-completed execution phase (P4). The active P5 phase will bump `phase: 5` and `stage` on the P5 ship commit. This is the expected state mid-P5 (audit in progress, ship not yet committed). Not a defect.
-
-### Observation: P3 commit lists REQ-009 as `partial`
-- **Note**: P3's `---ci---` block declares `partial: [REQ-009]`. This is honest soft-ordering accounting (Forex oracle is consumed by Piers; P3 ships the Forex half, P4 ships the L2 satellite half). REQ-009 is fully covered by P4's `x/satellite`. The `partial` flag is informational, not a coverage gap. Not a defect.

-## 4. Overall Audit Verdict
-
-### **PASS** (after critical fixes applied)
-
-The v0.2 (The Mesh) milestone is **shippable**.
-
-**Per-check summary:**
-
-| # | Check | Verdict |
-|---|---|---|
-| 1.1 | Reconstruction test (git log ↔ .ciagent, tags, milestone-not-released) | PASS |
-| 1.2 | .ciagent file discipline (9 files, CHECKPOINT.json, config.json) | PASS |
-| 1.3 | Branch hygiene (main, milestone, final-phase, no leftover branches) | PASS |
-| 1.4 | Commit discipline (`---ci---` blocks, project: oy, status, requirements) | PASS |
-| 1.5 | Build / test / cover sanity (build, test, ≥80% coverage, lexicon, invariants) | PASS |
-
-**Critical issues: 2 found → 2 fixed → 0 remaining.**
-- Critical-1 (REQUIREMENTS.md status column): FIXED.
-- Critical-2 (ROADMAP.md G-010 tag-line reconciliation + Phase 2 completion): FIXED.
-
-**Non-critical observations: 3** (2× P1 council spec drift + 1× P2 nit) — flagged for post-hoc review, do not block ship.
-
-**STRIDE security summary** (per ci-auditor role, read-only):
-
-| Category | Finding | Severity | Disposition |
-|---|---|---|---|
-| Spoofing | No auth surface (skeleton-only, zero deps); Reach IDs are opaque strings, no identity assertion logic | Low | Accept |
-| Tampering | Locked consts are compile-time `const` (Mission Lock, Bond cap/floor, Guild fee 0); `ValidateGenesis` rejects dup IDs + out-of-bounds bond coupons at genesis load | Low | Accept |
-| Repudiation | Append-only audit log (Window) with non-decreasing timestamp + entry-id uniqueness enforced; no tx log in skeleton (deferred Phase 3) | Low | Accept |
-| Info Disclosure | Zero secrets in code; lexicon firewall prevents leaking banned financial terms into the codebase (REQ-012); no PII handling in skeleton | Low | Accept |
-| Denial of Service | Rate-limit primitive (Window) is a simple counter (A-206); no network surface (zero deps, no relayer, no live oracle); DoS surface is Phase 3+ | Low | Accept |
-| Elevation of Privilege | Mission Lock (`const false`) prevents governance amending the covenant; Bond clamp prevents coupon above 8% cap; G-003 invariant prevents import-cycle privilege escalation via struct imports | Low | Accept |
-
-No threat exceeds the low/accept threshold. No escalations. The skeleton+tests scope (D-020) intentionally has no runtime attack surface; all security-relevant invariants are compile-time consts + tested firewalls.
-
-**Confidence in overall verdict: 0.90**

-## 5. Ship Readiness Confirmation
-
-The milestone is ready for the final ship step (P5-02-01):
-1. `go build ./...` GREEN ✓
-2. `go test ./...` GREEN (25 packages, no regression) ✓
-3. Coverage ≥80% on all 10 new/extended packages (floor 95.9%) ✓
-4. Lexicon firewall green (zero banned terms; meta-test + self-test table pass) ✓
-5. All locked-const invariants green ✓
-6. G-003 by-ID-string import invariant green ✓
-7. go.mod unchanged (G-006) ✓
-8. Tags v0.1.0..v0.1.4 exist and map to correct commits ✓
-9. v0.1.5 NOT yet present (correct — final phase creates it) ✓
-10. REQUIREMENTS.md + ROADMAP.md reconciled (Critical-1, Critical-2 fixed) ✓
-
-**Remaining P5 ship actions** (for the orchestrator, not the auditor):
-- Commit the P5 final-phase work (this AUDIT.md + the REQUIREMENTS.md/ROADMAP.md fixes + REVIEW.md).
-- Create the `v0.1.5` tag (= v0.2 milestone release per D-008/D-020).
-- (Optional) Update CHECKPOINT.json `phase: 5`, `stage: ship` on the P5 commit.
-- (If release_blocking were true) push tags to remote. config.json `ship.release_blocking: false`, so local tag is sufficient; remote push is at orchestrator discretion.

The Cosmos-convention-alignment load drops below the threshold that justified a separate persona. backend-engineer absorbs the 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).

-- **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).
-
-### 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.

-### 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.
-
-## Deactivated
-
-- **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.
-
-## Custom Personas
-
-- **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.
-
-## 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).
-
-## 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.

 ## Milestone
-v0.3 — Bearers & Documentation (active milestone; feature type; tags run on the v0.2.x patch line)
+v0.7 — Fraternal Groups Foundation (in progress; feature type; tags run on the v0.6.x patch line)
+
+### v0.7 Scope (Fraternal Groups Foundation — Cover Pools + Chapter Federation + Mutual Aid Bonds + Anti-Capture Bill v0.2)
+
+v0.7 adapts the 1890–1930 fraternal benefit-society model for borderless
+digital service. It delivers Cover Pools (insurance-like commitment pools
+with mission-locked reserve floors + Standing gates), Chapter Federation
+(Parent/Chapter Guild model with secession terms + good-standing liens
+declared at founding), Mutual Aid Bonds (Cover-Call-couponed bonds with
+issuance ceiling 3× annual surplus, use-of-proceeds locked to reserve
+build-out), and the Anti-Capture Bill of Rights v0.2 (13 rights codified,
+non-amendable, non-waivable by any Charter). This is the milestone that
+unblocks the v0.1 Q7 "Cover Pool seniority mechanics" deferred item —
+REQ-046..REQ-050 supply the seniority/gate math and promote `x/pact` Cover
+from skeleton to a dedicated `x/cover` module runtime (D-039 precedent:
+`x/hub` split out of `x/pact`'s `PactHubAPI` in v0.3).
+
+Simtest-grade runtime (D-020 pattern continues — no live chain launch, no
+mainnet). Cover Pool "live on testnet" (§7 acceptance) = `x/cover` keeper
+message handlers + simtest-grade end-to-end flows, not mainnet deployment.
+No `app.go`/`cmd/oyd` exists in the repo; v0.7 does not create one.
+
+New module: `x/cover` (Cover Pool Factory + Anti-Crowding-Out firewall +
+Anti-Capture Bill of Rights). The existing `x/pact` `PactCover` enum value
+remains as a cross-reference (G-003 by-ID-string pattern).
+
+- **REQ-046** Cover Pool Factory runtime — Factory rejects category launches below in-force reserve floor; supports Cover-Charter deployment; Watcher attestation pipeline operational; category staging per REQ-065.
+- **REQ-047** Cover Pool reserve target floor 1.5× annual contributions — LOCKED; mission-lock semantic enforced; below-floor auto-pause of Cover-Fee routing.
+- **REQ-048** Cover Pool reserve target ceiling 2.5× (governance-tunable within 1.5×–2.5×) — Watcher escalation after 12 months; Pool Council MAY vote within bounded range.
+- **REQ-049** Cover Pool Standing gate minimums — LOCKED; Travel ≥ Trusted 4.0; Health-MCS ≥ Preferred 4.5; Pool MAY tighten but NEVER loosen below protocol minimum. Binds at Factory runtime (D-077).
+- **REQ-050** Cover-Fee tagging at protocol layer — LOCKED; Cover-Fee Grains carry `category_tag`; settlement rejects category-mismatched Calls (FR-COVER-11); Pool-level fungibility preserved for net-reserve accounting.
+- **REQ-051** Guild Charter + Common Bond requirement — LOCKED; at formation: Common Bond declared + hash-pinned; Public Profile published (bond summary, disclaimers, Mason count or "private", Pier wrapper if any).
+- **REQ-052** Cover-Charter (SoB, dispute path, gate, holding period) — LOCKED; distinct from governance charter; signed by Pool Host + witnessed by Watcher at deployment; amendments require Pool supermajority + 7-day cooling + Watcher + Counsel; protocol does NOT enforce SoB content (FR-CHTR-5).
+- **REQ-053** Chapter Federation (Parent/Chapter, secession terms, liens at founding) — Parent Guild + Chapters; Chapters inherit + may tighten but not loosen; secession terms coded at founding; good-standing liens at founding (not freely increasable); Chapter retains mesh-level Voice (Pier does NOT carry Voice per FR-VOICE-6).
+- **REQ-054** Mutual Aid Bond (issuance ceiling 1×–3×, coupons in Cover Calls) — LOCKED; issuance ceiling mission-locked at 3× annual surplus; coupons payable in Cover Calls or mutual-aid credits (NEVER Bread); coupon rate bounded by `CouponCapBps=800`; use-of-proceeds locked to reserve build-out; default recapture per FR-MAB-7; Watcher attestation at deployment + quarterly audit. Enforcement: tagged streaming + Watcher-witnessed release (D-080, defense in depth).
+- **REQ-055** Cover Claims Voucher role + bond + slashing — Specialization of Voucher role; bond default 10× avg Call size per Pool; reviews each Call independently (no self-adjudication, FR-CPCV-2); slashing via §9.4 mechanism with cross-Pool applicability (NFR-SEC-8); bounded earnings.
+- **REQ-056** Anti-Capture Bill of Rights v0.2 — LOCKED; 13 rights codified in code; cannot be amended or waived by any Charter; covers one-tap exit, no tax on personal Stash, audit-able Voice, cooling, Watcher inspection, Freeholder voucher, Counsel escalation, Anchored-Bread conversion, Wayfarer's Record, secession (founding terms), non-Cover-access, category-mismatch refusal.
+- **REQ-057** Household simplified — no formal Council, one-tap exit — Household Stand may operate without formal Council; one-tap exit is the dispute path.
+- **REQ-058** Confederation Voice — one-Stand-one-Vote, internal bundle — LOCKED; Confederation aggregates member Stand Voice one-per-Stand; member Stands may bundle delegated Voice internally via §19 delegation.
+- **REQ-059** Stand→Pier-customer boundary — escalation rule ($100k per D-074) — When annual Pass volume > $100k, Stand is invited to Hub API; soft upgrade, not a ban.
+- **REQ-060** Shadow vouch partial credit — 50% weight in Freeholder signal — LOCKED; Shadow vouch weight = 0.5× in Community Endorsement signal (vs 1.0× for non-Shadow vouch).
+- **REQ-061** Disclaimer cadence — per charter signing — LOCKED; jurisdictional disclaimer surfaced at every charter signing; not session-bounded.
+- **REQ-062** Pool governance hybrid (Host + 3 elected + Watcher observer) — LOCKED; Cover Pool Council = Pool Host + 3 Masons elected by Pool-eligible Masons + Watcher observer seat; Cover Calls require majority with Watcher observer present. No Anchor seat (Anchor no-Voice §5).
+- **REQ-063** MAB holder — surplus seniority only, no Voice at dissolution — LOCKED; Mutual Aid Bond holders rank after Cover-Fee contributors but before Bread holders in Pool-surplus distributions (FR-MAB-4); NO Voice in Pool dissolution decisions (claimants, not Masons).
+- **REQ-064** Secession cooling — 21d Cover-active / 14d non-Cover — LOCKED; Chapter secession cooling: 21 Mesh-days if Cover-active, 14 Mesh-days if non-Cover; secured at founding, not reducible; lien audit required; Cover Call / Bond covenant clearance required before secession completes.
+- **REQ-065** Cover Pool category staging — Phase 2/3/4 — LOCKED; Phase 2: Travel + Health-MCS + Income-Pause; Phase 3: Equipment/Loss + Life-Burial + Road-Side; Phase 4: Cyber-Skimming + Guild-Internal-Mutual-Aid; Factory respects staging and rejects out-of-phase launches.
+- **REQ-066** Pier selection — Guild Council chooses, reversible, Pier Selection Index — Guild Council chooses Pier at formation; reversible by Cover Pool supermajority + Counsel witness; mesh maintains Pier Selection Index; Pier-Routed Legal Wrapper OPTIONAL (§5 default-no-wrapper).
+
+### Milestone Type
+Feature (REQ-046..REQ-066 are feat-class primitives + test adjuncts for the firewall). Phase 0 → `v0.6.0`; execution phases `v0.6.1..v0.6.5`; final phase patch `v0.6.6` IS the v0.7 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 — `x/cover` keeper uses existing cosmos-sdk runtime substrate).
+
+### Out of Scope (v0.7)
+- Real blockchain interaction / mainnet / IBC / real bearer transports (D-020 continues; runtime = simtest-grade keeper handlers)
+- A real `oyd` daemon / `app.go` / `cmd/oyd` (no chain runtime exists; deferred to v0.8+)
+- Sovereign Anchor SPEC (`oy-sovereign-anchors` forthcoming; experimental, not load-bearing per §5/D-076)
+- USZ classification runtime (v0.8 — depends on Anchor pre-commitment framework, REQ-095)
+- Cluster A–E + Infrastructure Economics (REQ-067..REQ-097, all v0.8 per D-081)
+- Pier-Routed Legal Wrapper (OPTIONAL per §5; default-no-wrapper; not implemented as code)
+- Authentication / sessions / real key management (mock; deferred to v0.8+)
+- Persistence (mock store; deferred to v0.8+)

+
+## Prior Milestone
+v0.6 — Nomad Web UI (complete; feature type; tags ran 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

+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).

+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

No separate minor tag. | The candidate work set (REQ-029..REQ-032) is entirely refactor/test/quality/chore.

+| 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/`.

+| 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.

+|----|----------|-----------|------------|--------------|
+| 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)] |

+## Clarification Decisions (Phase 0 v0.7 — CLARIFY, autonomy=full)
+
+Auto-decided defaults logged per clarify workflow Step 4 (full autonomy → accept defaults, log decisions). No `--ideate` flag this run; v0.7 scope is pre-seeded from oy-spec v3 §7 (Fraternal Groups Foundation, REQ-046..REQ-066) and ratified at CLARIFY. All 8 §8 open questions resolved by accepting PO recommendations as binding (D-074..D-081). The D-001 refinement-only filter does NOT apply (v0.7 is a feature milestone). Three scope-shaping questions were validated interactively with the user before CLARIFY:
+
+1. **v0.7 scope (§7 vs §8 Q4)** — user ruled: §7 only (REQ-046..REQ-066, 21 REQs). Cluster A+B+C are v0.8 (D-081).
+2. **Accept all other PO recommendations** — user ruled: yes, accept all 7 (D-074..D-080) as binding.
+3. **Generate oy-state v2 at P0 start** — user ruled: yes (done at SPECIFY).
+
+| ID | Decision | Rationale | Confidence | Alternatives |
+|----|----------|-----------|------------|--------------|
+| D-074 | **TBD-X = $100k annual Pass volume** for Stand→Pier-customer boundary escalation (REQ-059). When a Stand's annual Pass volume exceeds $100k (10,000,000 Grain-cents at GrainsPerBread=10000), the Stand is invited to the Hub API as a soft upgrade (not a ban). The threshold is a new `x/stand` const `StandPierEscalationAnnualPassVolumeCents=10000000` (not locked — Pool/Council may tune within bounds). | §8 Q1 PO rec accepted at full autonomy. $100k is the natural inflection where a Stand's activity volume resembles a small Pier-customer more than a personal Holder; soft upgrade preserves self-service (Principle 6). | 0.85 | [$50k (too aggressive — flags mature Households); $250k (too lax — delays Hub API onboarding)] |
+| D-075 | **TBD-Z density formula for USZ classification (REQ-095, v0.8)** = `<10 Holders per km² AND strategic value ≥ mission score, OR sovereign request, OR mission-aligned override via Mesh Council supermajority`. The formula is locked now (oy-state §3) but the USZ runtime is v0.8 (depends on Anchor pre-commitment framework). | §8 Q2 PO rec accepted. The 3-criteria OR structure matches the spec's "≥3 criteria" requirement (density + strategic value + mission-aligned override) while allowing sovereign request as a separate path. | 0.80 | [pure density threshold (ignores strategic value); Mesh Council sole arbiter (no objective floor)] |
+| D-076 | **Sovereign Anchors = separate SPEC `oy-sovereign-anchors`**, not folded into `oy-pier`. v0.7 status: experimental, not load-bearing. The `oy-spec` §5 constraint forbids USZ infrastructure financing via Sovereign Anchor partnerships from being load-bearing until the separate SPEC ships. | §8 Q3 PO rec accepted. Sovereign Anchors are infrastructure-scale (reserve entities, banking partners, multi-jurisdiction custody) — a different design surface than the Pier-Routed Legal Wrapper (which is OPTIONAL per §5). Folding them into `oy-pier` would conflate legal-wrapper-scale with infrastructure-scale. | 0.85 | [fold into oy-pier (conflates scales); fold into oy-spec (too large for the net-new-only diff)] |
+| D-077 | **Standing gate enforcement timing = Cover Pool Factory runtime (v0.7/P1)**, not first live Cover Pool deployment. The `CoverStandingGateTrusted=4.0` and `CoverStandingGatePreferred=4.5` consts bind at the `x/cover` Factory layer — every Pool the Factory launches inherits the protocol minimum; Pool Council MAY tighten but the Factory rejects any launch below the floor. | §8 Q5 PO rec accepted. Gates are protocol-layer invariants (REQ-049 locked=yes); deferring them to first-live-Pool would allow a window where a Pool could launch below the floor. Factory-runtime binding closes the window. | 0.88 | [first-live-Pool binding (allows a below-floor window); per-Pool configurable with no floor (violates REQ-049 locked)] |
+| D-078 | **Watcher/Voucher operating-expense compensation cap = 5% of Root-Pool Bloom annually** (REQ-096, v0.8). The absolute $TBD-W cap is deferred to v0.8 P0 (needs Root-Pool Bloom size estimate). v0.7 does not implement Watcher/Voucher compensation (Cluster E + Infra Economics are v0.8 per D-081). | §8 Q6 PO rec accepted. 5% Bloom is bounded by the protocol's own yield (not a transfer-payment analog); the absolute cap prevents Bloom-rate collapse if Bloom grows large. Deferring $TBD-W avoids hardcoding a USD figure that depends on mainnet Bloom size. | 0.82 | [10% (too high — risks Bloom-rate dilution); 1% (too low — may not cover Watcher ops); no absolute cap (unbounded if Bloom grows)] |
+| D-079 | **Anti-Crowding-Out Covenant enforcement = separate `x/cover/firewall` package (runtime) + `lexicon_meta_cover`-style meta-test (test-time)**, defense in depth. The runtime subpackage rejects any code path that would route Cover-Fees outside contributor-pool semantics (e.g., to Root-Pool operating expenses, transfer payments, or non-Cover destinations). The meta-test rejects doc/string drift that would describe such routing. This parallels the lexicon_meta pattern (D-044/D-069 firewall-first). | §8 Q7 PO rec accepted. The covenant is a §1/§2.3 SPEC-001 invariant — "Cover-Fees never crowd out the contributor pool". A separate firewall (not embedded in Factory validation) makes the invariant visible, testable, and resistant to Factory-layer refactors. Defense in depth: runtime rejects the code path, meta-test rejects the doc drift. | 0.84 | [embed in Factory validation (invisible, refactorable); meta-test only (no runtime gate — docs clean but code could route around)] |
+| D-080 | **MAB use-of-proceeds lock enforcement = tagged streaming + Watcher-witnessed release**, defense in depth. MAB proceeds are tagged with `use_of_proceeds=reserve_build_out` at issuance; the `x/bond` keeper streams tagged Grain to the `x/cover` reserve only, with auto-Still on any misuse detection (attempt to route to a non-reserve destination). Watcher attestation witnesses each release at quarterly audit (REQ-054). | §8 Q8 PO rec accepted. Tagged streaming makes the lock enforceable at the keeper layer (not just auditable post-hoc); Watcher-witnessed release adds the human-attestation layer. Defense in depth: keeper auto-Stills on misuse, Watcher catches what the keeper misses. | 0.85 | [Watcher-quorum-only release (no runtime gate — relies on Watcher catching misuse after the fact); unrestricted + audit-only (no enforcement, just detection)] |
+| D-081 | **v0.7 scope = §7 authoritative — REQ-046..REQ-066 only (21 REQs).** Cluster A+B+C (REQ-067..REQ-081) are v0.8, NOT v0.7, despite §8 Q4 PO rec suggesting Cluster A+B+C ship in v0.7. The §7 v0.7 acceptance text lists only REQ-046..REQ-066; the §7 v0.8 acceptance text lists REQ-067..REQ-097 with the const firewall extensions. §7 is the milestone contract; §8 Q4 was a recommendation the PO can override — and did, by accepting the "§7 only" interactive ruling before CLARIFY. | §7 acceptance text is the authoritative milestone contract (it lists the REQs and the acceptance criteria). §8 Q4 was a sequencing recommendation, not a binding scope ruling. Shipping 36 REQs in v0.7 would create a mega-milestone with coupled territories (fraternal primitives + their risk mitigations are different vertical slices). v0.7 = foundation; v0.8 = hardening. | 0.90 | [§8 Q4 — Cluster A+B+C in v0.7 (36 REQs, coupled territories); §7 + partial Cluster A only (REQ-067..072, 27 REQs — still couples fraternal + trust-minimization)] |
+| D-082 | **v0.7 phase ordering** (provisional, planner finalizes): P1 Cover Pool firewall + foundation (REQ-046/047/049/050 — firewall-first, same `x/cover` territory) → P2 Cover-Charter + Council + staging (REQ-048/052/062/065 — extends `x/cover` + `x/council`) → P3 Guild Charter + Chapter Federation (REQ-051/053/057/058/061 — extends `x/guild`, `x/stand`) → P4 MAB + Cover Claims Voucher (REQ-054/055/060/063 — extends `x/bond`, `x/standing`, `x/cover`) → P5 Anti-Capture Bill + secession + Pier (REQ-056/059/064/066 — cross-cutting, lands last as it constrains all prior surfaces) → P6 final review + audit + milestone ship. Each phase independently shippable; P1 lands the firewall + locked floors first (firewall-first pattern per D-044/D-069/D-079). | The 21 REQs cluster into 5 vertical slices by module territory + dependency. P1 is the spine (Factory + firewall + locked floors + gates + tagging); everything else hangs off it. P5 lands last because the Anti-Capture Bill constrains all prior surfaces (non-amendable rights that P1-P4 code must not violate). | 0.82 | [governance-first (REQ-062 first — but it depends on Factory); MAB-first (REQ-054 — but it depends on Cover Pool reserve existing); single mega-phase (couples territories)] |
+| D-083 | **No IDEATE stage in v0.7** (no `--ideate` flag this run). The feature scope was pre-seeded from oy-spec v3 §7 (REQ-046..REQ-066) and ratified at CLARIFY with all 8 §8 questions resolved. The D-001 refinement-only filter does NOT apply (v0.7 is a feature milestone). | run.md §IDEATE is conditional on `--ideate`. This invocation has no `--ideate`. | 1.00 | [run IDEATE anyway] |
+| D-084 | **New module `x/cover`** (Cover Pool Factory + Anti-Crowding-Out firewall + Anti-Capture Bill of Rights). The existing `x/pact` `PactCover` enum value remains as a cross-reference (G-003 by-ID-string pattern). This mirrors the D-039 precedent (`x/hub` split out of `x/pact`'s `PactHubAPI` in v0.3) — when a PactType grows into a first-class protocol surface with its own keeper + firewall, it graduates to a dedicated module. The `x/pact` `PactCover` enum value stays as a typed cross-reference so `x/pact` tests still pass; `x/cover` owns the runtime. | REQ-046 (Factory runtime), REQ-047 (reserve floor in `x/pact/cover` per spec text — interpreted as `x/cover` since that's where the Factory lives), REQ-050 (Cover-Fee tagging at protocol layer), REQ-052 (Cover-Charter), REQ-055 (Cover Claims Voucher), REQ-056 (Anti-Capture Bill) all need a home. A dedicated `x/cover` module is the D-039 pattern; keeping them in `x/pact` would overload `x/pact` (which is a 6-Pact enum skeleton, not a Cover Pool runtime). The spec text "codified in `x/pact/cover`" is read as "the Cover surface, which graduated from `x/pact`" — `x/cover` is the graduated module. GRILL ratifies. | 0.82 | [keep everything in `x/pact` (overloads the 6-Pact enum module); create 3 micro-modules (`x/coverpool`, `x/covercharter`, `x/anticapture` — fragments the Cover surface)] |
+
+## GRILL Decisions (Phase 0 v0.7 — GRILL, autonomy=full)
+
+The ci-griller red-teamed the v0.7 plan across 9 axes + 7 specific probes. Overall verdict: **CONDITIONAL PASS** (confidence 0.72) with 5 binding decisions (D-086..D-090) and 3 escalations to PO. The plan does NOT proceed to P1 until D-086..D-090 are applied (they are applied to PLANS.md + ARCHITECTURE.md + this file). This grill IS the self-administered adversarial review (pen-test) per oy-state §7 remaining-open item 4.
+
+| ID | Decision | Rationale | Confidence | Affects |
+|----|----------|-----------|------------|--------|
+| D-086 | **P1 Factory scope clarification** — P1's `MsgLaunchCoverPool` is *functional for Phase-2 categories ONLY* (Travel/HealthMCS/IncomePause). `FactoryAllowedPhases` Params field set to `[Phase2]` only in P1; Phase3/Phase4 categories REJECTED in P1. P2 extends to `[Phase2, Phase3, Phase4]`. P1 simtest includes negative case: out-of-phase category launch rejected. | The plan's "placeholder" language was ambiguous. Pinning P1 to Phase-2-only makes the vertical slice honest: P1 ships a working Factory for the Phase-2 subset, not a half-Factory. | 0.82 | PLANS P1 |
+| D-087 | **`PierCarriesVoice` const reconciliation** — P3 introduces `PierCarriesVoice bool const false` in `x/guild/types` (FR-VOICE-6: Pier does NOT carry Voice). Added as the **12th locked const** to the v0.7 const additions table (was 11; now 12). Mission-locked invariant — const is the correct firewall shape (not a field). | The plan and the const table disagreed by 1. A const that exists in code but not in the firewall table is invisible to the regression firewall. | 0.80 | PLANS const table, oy-state §3, ARCHITECTURE const table |
+| D-088 | **`lexicon_meta_cover` banned-term list + firewall shape** — (1) The `lexicon_meta_cover/` meta-test uses a NEW `lexicon.CoverBannedTerms()` helper banning `insurance`, `premium`, `claim`, `policy` scoped to the Cover surface (NOT project-wide — avoids false positives in non-Cover modules where "claim" is a common English word). (2) The `x/cover/firewall/` runtime subpackage shape is pinned to an **allow-list of permitted routing destinations** (the Pool's `ReserveAccount`), checked via string-equality at the start of every `MsgRouteCoverFee` handler. (3) **Optional cleanup:** replace `x/pact` "insurance-like" docstrings (`x/pact/types/types.go:36,158`) with "Cover-like" as a P1 doc-fix. | (1) Without a defined banned-term list, the `lexicon_meta_cover` meta-test was a paper tiger — it scanned but didn't ban the terms the plan said are banned. (2) The firewall's "rejects any code path" language was aspirational; an allow-list is the simtest-grade concrete form. (3) The `x/pact` "insurance-like" string is latent lexicon debt. | 0.78 | PLANS P1, `lexicon/lexicon.go`, `x/pact/types/types.go` |
+| D-089 | **`StillKeeper` stub + `x/bond → x/cover` CoverKeeper reverse edge** — (1) `StillKeeper.Still(poolID, reason)` is satisfied by a **simtest-local stub** (test-only, G-003 exempt), NOT a real `x/still` keeper. `x/still` is NOT extended this milestone (verified: `x/still/keeper/` is empty). (2) ARCHITECTURE.md v0.7 dependency map adds the reverse edge: `x/bond ──(CoverKeeper shim)──► x/cover` (the MAB `MsgDebitMABProceeds` handler queries `CoverKeeper.GetPoolReserveAccount(poolID)`). NEW expected-keeper interface in `x/bond/types/expected_keepers.go`. No import cycle (interface only). | (1) The auto-Still hook references a method that doesn't exist; without a documented stub, P4 cannot wire the simtest. (2) The reverse dependency edge is real (MAB handler must query the Pool's reserve account) but undocumented — a hidden architecture coupling. | 0.76 | PLANS P1/P4, ARCHITECTURE dependency map, `x/bond/types/expected_keepers.go` |
+| D-090 | **Bill of Rights temporal gap + Voucher cold-start + Standing-gate dual check + D-085 window** — (1) **Bill of Rights temporal-gap fix (most serious):** the `RightID` type + 13 `Waivable*` consts (all `false`) + `RightIsWaivable(id) bool` (always `false`) + `MsgSignCoverCharter.ValidateBasic` gate rejecting any `WaivedRights` element land in **P2** (before the first Charter can be signed), NOT P5. P5 adds the *ceremony* surface (Counsel review handler, full simtest). (2) **Voucher bond cold-start fix:** `bond = max(CoverClaimsVoucherBondMultipleAvgCall × avgCallSize, MinimumVoucherBond)` where `MinimumVoucherBond` is a Params field with a non-zero default. (3) **Standing-gate dual check:** the `CoverStandingGateTrusted`/`CoverStandingGatePreferred` floor is enforced at BOTH the `MsgLaunchCoverPool` handler AND the `MsgAmendPoolStandingGate` (Params-amendment) `ValidateBasic`. (4) **D-085 escalation window tightened to before P2** (because D-090(1) moves the RightID + 13 consts to P2). Fallback at P2: log `RightNonParticipationNoDenial` as the 13th right at confidence 0.55 and proceed. | (1) The P2→P5 temporal gap was a real security hole — rights waivable between P2 and P5. (2) Zero-bond cold-start was a Voucher bypass. (3) A Params-only check left the amendment path open. (4) The escalation window must match the new P2 deadline. | 0.72 | PLANS P2, P4, P5, RESEARCH D-085 |

+
+## 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).

+## 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 | Complete | 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 | Complete | 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 | Complete | 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 | Complete | 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 | Complete | 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 | Complete | 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.
+
+## v0.7 Milestone Requirements (Fraternal Groups Foundation — Feature)
+
+v0.7 adapts the 1890–1930 fraternal benefit-society model for borderless
+digital service. It delivers Cover Pools (mission-locked reserve floors +
+Standing gates), Chapter Federation (Parent/Chapter Guild model with
+secession terms + good-standing liens at founding), Mutual Aid Bonds
+(Cover-Call-couponed, 3× annual surplus ceiling, use-of-proceeds locked to
+reserve build-out), and the Anti-Capture Bill of Rights v0.2 (13 rights
+codified, non-amendable, non-waivable). This milestone unblocks the v0.1 Q7
+"Cover Pool seniority mechanics" deferred item — REQ-046..REQ-050 supply the
+seniority/gate math and promote `x/pact` Cover from skeleton to a dedicated
+`x/cover` module runtime (D-084, D-039 precedent).
+
+Simtest-grade runtime (D-020 pattern continues — no live chain launch, no
+mainnet). Cover Pool "live on testnet" (§7 acceptance) = `x/cover` keeper
+message handlers + simtest-grade end-to-end flows. No `app.go`/`cmd/oyd`
+exists; v0.7 does not create one. New module: `x/cover` (Factory + Anti-
+Crowding-Out firewall + Anti-Capture Bill of Rights). The existing `x/pact`
+`PactCover` enum value remains as a cross-reference (G-003 by-ID-string).
+
+| ID | Requirement | Vision § | Priority | Status | Phase |
+|----|-------------|----------|----------|--------|-------|

Enforcement: tagged streaming + Watcher-witnessed release (D-080) | §17 | High | Not started | v0.7/P4 |
+| REQ-055 | Cover Claims Voucher role + bond + slashing — Specialization of Voucher role; bond default 10× avg Call size per Pool; reviews each Call independently (no self-adjudication, FR-CPCV-2); slashing via §9.4 mechanism with cross-Pool applicability (NFR-SEC-8); bounded earnings | §9.4, §15 | High | Not started | v0.7/P4 |
+| REQ-056 | Anti-Capture Bill of Rights v0.2 — LOCKED; 13 rights codified in code; cannot be amended or waived by any Charter; covers one-tap exit, no tax on personal Stash, audit-able Voice, cooling, Watcher inspection, Freeholder voucher, Counsel escalation, Anchored-Bread conversion, Wayfarer's Record, secession (founding terms), non-Cover-access, category-mismatch refusal | §8.2 [3] | High | Not started | v0.7/P5 |

+
+> REQ-046..REQ-066 are NEW in v0.7. All are `feat`-class primitives (Cover
+> Pool Factory, Cover-Charter, Chapter Federation, MAB, Cover Claims Voucher,
+> Anti-Capture Bill) + a `test` adjunct for the Anti-Crowding-Out firewall

+- IDEATE-10..13 ship in P2..P5 (one screen per phase, ordered by the Nomad happy path: Reach → Stash → Window → Standing → Bloom).
-- IDEATE-03..08 (Bearers skeleton) are the ROADMAP Phase 3 subset bundled into
+- The D-001 refinement-only filter does NOT apply (v0.6 is a feature milestone, not NFR).

-## Verification Commands Run
+1. **`go run ./web` starts with no external deps (G-006)** — PASS. `git diff v0.5.0..HEAD -- go.mod go.sum` is empty. HTMX is a vendored static asset (`web/static/htmx.min.js`), NOT a `go get`. Zero new require lines across the v0.6 milestone.
+2. **All 5 screens reachable from the home page** — PASS. Nav in `web/templates/base.html` links to /reach, /stash, /window, /standing, /bloom. Each route returns 200 (handler tests + smoke test on dynamic port 47077/53907).
+3. **`lexicon_meta_web/` firewall scans `web/templates/**` + `web/static/**` + `web/**/*.go`** — PASS. `go test ./lexicon_meta_web/...` green; G-013 walk-coverage test injects a synthetic banned-term fixture and finds it.
+4. **Bread-scale conversion matches `x/bread/types` code constants (D-073)** — PASS. `TestStashBreadScaleConversionCorrectness` asserts GrainsPerBread=10000, Crumb=100 Grain (code values); would FAIL if the outdated docs 1000x values were used.
+5. **Standing score uses locked formula constants** — PASS. `TestStandingScoreComputedFromLockedConstants` asserts PriorMean=4.0, PriorWeight=10, ComputeDiversityBonus, GetVoucherWeight, GetStandingBucket (all from x/standing/types, NOT hardcoded).
+6. **Freeholder-eligible badge reflects `IsFreeholderEligible()`** — PASS. `TestFreeholderEligibleBadgeReflectsMethod` asserts the rendered badge matches the real method output for both eligible (holder-alia) and non-eligible (holder-bryn) Reaches.
+7. **Window lifecycle transitions call `Window.Activate/Revoke/Expire`** — PASS. `TestWindowActivateTransitionsOpenToActive` + `TestWindowRevokeTransitionsToRevoked` assert the real x/window/types methods are invoked (status transitions verified). `TestWindowRevokeOnExpiredIsNoOp` asserts the v0.2 terminal-state contract (revoke-on-expired is a no-op).
+8. **No banned terms in any rendered page** — PASS. Per-handler rendered-HTML lexicon checks (G-026) in all 5 phases scan BOTH 200 happy-path AND error response bodies (400/404). `lexicon_meta_web/` file-scan firewall green on all web/**/*.{html,js,go} files.

-## 1. Per-Axis Verdicts
-
-### Axis 1 — Correctness — **PASS** (confidence 0.90)
-
-Verified every locked const, enum count, struct shape, and ValidateGenesis ID-uniqueness check against RESEARCH.md §1 + PLANS.md task specs:
-
-| Component | Locked const / enum | Spec | Code | Verdict |
-|---|---|---|---|---|
-| Window | `WindowStatusCount` | 4 (Open/Active/Revoked/Expired) | `=4` ✓ | PASS |
-| Stand | `StandTypeCount` | 9 (Household/Crew/Entity/Co-op/Circle/Trust/Foundation/Confederation/Shadow) | `=9` ✓ all 9 names match vision §11 | PASS |
-| Guild | `HandPassFeeBps` | 0 | `=0` ✓ + FeeGrain==0 enforced in ValidateGenesis | PASS |
-| Pact | `PactTypeCount` | 6 (Pause/Ground/Stance/Cover/StandRegistry/HubAPI) | `=6` ✓ | PASS |
-| Pact | `MissionLockAmendable` | false | `=false` ✓ + per-type `AmendableCoreTermsPause/Ground/Stance=false` ✓ | PASS |

-| Satellite | `ChannelStatusCount` | 4 (Init/TryOpen/Open/Closed) | `=4` ✓ ICS-20 v1 shape | PASS |
-
-**ValidateGenesis ID-uniqueness checks (A-212 upgrade from v0.1 no-op)** — all present and tested:
-- window: dup window-ids ✓ + audit-log entry-id uniqueness + non-decreasing timestamps ✓
-- stand: dup stand-ids ✓ + dup (stand-id, reach-id) membership pairs ✓
-- guild: dup guild-ids ✓ + dup pass-ids ✓ + FeeGrain==0 covenant ✓
-- pact: dup pact-ids ✓ + known-type check ✓ + Mission-Lock echo ✓
-- partner: dup partner-ids ✓
-- council: dup council-ids ✓ + dup voice-ids ✓ + referential integrity (voice→council) ✓ + Stand/Guild Council ref-required ✓

-- bond: dup bond-ids ✓ + coupon clamp at genesis load ✓ + known-status ✓
-- satellite: dup channel-ids ✓ + dup denoms ✓
-- bearers: no-op (correct — spec said "DefaultParams/GenesisState unchanged"; extension is types-only)
-
-**Correctness caveat (P1, not blocking):** the council module's *governance lifecycle shape* is simpler than the P3-01-01 deliverable recommended (see P1+ flags below). All must-haves are met; the drift is in the non-must-have Proposal/VoteOption lifecycle enums.
-
-### Axis 2 — Security — **PASS** (confidence 0.92)
-
-- **Lexicon firewall (G-002, REQ-012)**: zero banned terms in any `x/**/*.go` (verified by `TestLexiconMetaNoBannedTermsInX` + independent `grep` word-boundary scan, exit 1 = no matches). The firewall is NEW in v0.2 and green from P1. The `lexicon/lexicon.go` package bootstraps terms from two-character fragments so the firewall's own source contains no banned literals (standard lexicon-test bootstrapping pattern).
-- **G-003 by-ID-string invariant**: `TestG003NoCrossModuleStructImportsInProduction` (x/window/types/types_test.go:437) scans every non-test `.go` under `x/` with `go/parser` and asserts no production file imports a foreign `x/<module>/types` package. Test passes. Independent grep confirms: the only cross-module `oy/openyield/x/...` imports in test files are self-imports (test pkg → its own types pkg) + the pre-existing v0.1 `x/bearers` test → `x/processing/types` (a test import, not production).
-- **Mission Lock**: `MissionLockAmendable = false` as compile-time `const` in BOTH `x/pact/types` (line 24) and `x/council/types` (line 25). Per-type `AmendableCoreTermsPause/Ground/Stance = false` consts in pact. Tests assert the const is false AND that the typed comparison would fail to compile if the const changed type (defence in depth).
-- **Bond Clamp invariants**: `Clamp(couponBps)` enforces `min(cap, max(floor, coupon))` at both construction (`Issue`) and genesis load (`ValidateBonds`). Tested for above-cap→cap, in-range→unchanged, below-floor boundary. The genesis path rejects out-of-bounds coupons rather than silently clamping (authoritative schema).
-- **No secrets in code**: no credentials, API keys, or private material present (skeleton-only, zero external deps).
-
-### Axis 3 — Maintainability — **PASS** (confidence 0.90)
-
-- **v0.1 pattern consistency**: all 10 packages follow the v0.1 skeleton convention — `package types`, `ModuleName`/`StoreKey`/`RouterKey`/`QuerierRoute` consts, typed structs with `json`+`yaml` tags, `Params` struct, `DefaultParams()`, `GenesisState`, `DefaultGenesisState()`, `ValidateGenesis(json.RawMessage) error`. No drift from the v0.1 layout.
-- **Table-driven tests**: present throughout (window rate-limit, bond clamp, lexicon self-test, lexicon false-positive, partner keeper round-trip, council genesis validation). Matches v0.1's 53-test baseline pattern (now 299 tests across 23 files — v0.1 baseline preserved + v0.2 additions).
-- **Coverage ≥80%**: all 10 new/extended packages exceed 80% (floor 95.9%, 8 of 10 at 100%). D-033 satisfied.
-- **No external deps added**: `git diff main..oy/milestone/v0.2-mesh -- go.mod` is EMPTY. G-006/A-201 zero-dep invariant intact. All v0.2 code compiles with stdlib only (`encoding/json`, `fmt`, `sync`, `regexp`, `strings`, `os`, `path/filepath`, `runtime`, `testing`, `go/parser`, `go/token`).
-- **G-008 genesis schema vs test split**: `genesis.go` files (data-engineer schema) present in window, stand, bond, council, forex, pact, satellite. `*_test.go` files (security-engineer) own all test assertions including `genesis_test.go` (present in window, stand, bond). Helper composition is clean: `ValidateGenesis` in `types.go` delegates to `Validate*` helpers in `genesis.go`.
-
-### Axis 4 — Adversarial — **CONDITIONAL** (confidence 0.78)
-
-- **No double-counted REQs**: every v0.2 REQ (009, 011, 015, 016, 017, 018, 020, 021, Bearers, Forex) maps to exactly one module + test task. REQ-012 (lexicon) is cross-cutting (per-module + project-wide meta-test).
-- **No missing must-haves**: all P1-P4 must-have checklists satisfied (verified per phase in §3 below).
-- **Spec drift detected (P1, non-blocking)**: the council module's P3-01-01 deliverable recommended a full OZ Governor / `x/gov` proposal lifecycle (`Proposal` struct, `ProposalStatus` enum with 5 states, `VoteOption` enum with 3 options) plus a 5-source `VoiceSource` enum (Stash/Standing/Vouch/Freeholder/Guild). The implemented code has a simpler `Voice` + `TallyResult` shape, renamed `VoiceSource`→`SignalKind` with 4 sources (Stash/Standing/Vouch/Capital — dropped Freeholder and Guild, added Capital), and no Proposal/ProposalStatus/VoteOption enums. The P3 must-haves (3 councils, Mission Lock, TallyResult x/gov shape, no veto) are ALL met — the drift is in the non-must-have lifecycle enums. Flagged P1 for v0.3 (see §2).
-- **No other drift**: all other modules match their task deliverables exactly (locked consts, struct fields, enum names, genesis invariants).
-
-### Axis 5 — Grill Binding Decisions — **9 APPLIED + 1 N/A** (see §4)
-
----
-
-## 2. P0 Issues + Auto-Applied Fixes
-
-**P0 count: 0.** No P0 issues found. No auto-applied fixes.
-
-Rationale: all locked consts are correct, all ValidateGenesis ID-uniqueness checks are present, the lexicon firewall is green, G-003 import invariant is tested and green, Mission Lock and Bond Clamp invariants are const-enforced and tested, go.mod is unchanged, coverage exceeds 80% everywhere. The two spec-drift findings (council lifecycle enums) are P1 — they do not break any must-have, do not introduce a security hole, and do not affect the locked-const firewall. They are flagged for post-hoc review, not auto-fixed (auto-fixing would mean designing the Proposal/VoteOption lifecycle, which is a design decision the orchestrator should make in v0.3, not a P0 patch).
-
----
-
-## 3. P1+ Issues for Post-Hoc Review (flag, don't fix)
-
-### P1-1: Council module — Proposal/VoteOption lifecycle enums absent
-- **File:line**: `x/council/types/types.go:33-145` (entire council types file)
-- **Spec (P3-01-01 deliverable)**: `Proposal` struct (id, council, proposer-reach, submit-time, voting-period, status); `ProposalStatus` enum (Pending, Active, Succeeded, Failed, Executed — mirror OZ/Governor + `x/gov`); `VoteOption` enum (Yes, No, Abstain — no "no-with-veto", anti-greed).
-- **Implemented**: `Council`, `CouncilMember`, `Voice`, `SignalKind`, `TallyResult`. No `Proposal`, no `ProposalStatus`, no `VoteOption`. The `Voice` struct carries a `TallyResult` directly, collapsing the proposal→vote→tally lifecycle into a single Voice cast.
-- **Must-have impact**: NONE. P3 must-haves were: 3 councils ✓, Mission Lock ✓, TallyResult mirrors x/gov ✓, VoteOption has no veto (N/A — no VoteOption enum at all). The must-haves do not require the Proposal/VoteOption enums; they were in the task deliverable description, not the must-have checklist.
-- **Recommendation for v0.3**: when wiring the council keeper to a live governance runtime, add `Proposal` + `ProposalStatus` (Pending→Active→Succeeded→Failed→Executed) + `VoteOption` (Yes/No/Abstain) so the council can run an actual proposal lifecycle. The current `Voice`+`TallyResult` shape is sufficient for the skeleton's tally-structure goal but insufficient for live governance.
-- **Severity**: P1 (spec drift from deliverable, not a must-have, not blocking).
-
-### P1-2: Council VoiceSource→SignalKind (4 sources, not 5)
-- **File:line**: `x/council/types/types.go:102-129` (`SignalKind` enum + `AllSignalKinds()`)
-- **Spec (P3-01-01 deliverable)**: `VoiceSource` enum (Stash, Standing, Vouch, Freeholder, Guild) — 5 multi-source weighting inputs.
-- **Implemented**: `SignalKind` enum (Stash, Standing, Vouch, Capital) — 4 sources. "Freeholder" and "Guild" dropped; "Capital" added.
-- **Code rationale (types.go:104-114)**: the comment explains Capital as "committed-capital signal (vision §9.1 committed_capital)" and argues Freeholder is an eligibility property (upstream in `x/standing`), not a voice signal, and Guild is a council tier, not a voice source. This is a defensible design refinement — but it diverges from the P3-01-01 deliverable text.
-- **Must-have impact**: NONE. P3 must-haves did not enumerate VoiceSource coverage; only "Mission Lock invariant" and "TallyResult x/gov shape" were must-haves.
-- **Recommendation for post-hoc review**: confirm with the lead-developer/cosmos-engineer that the 4-source `SignalKind` (Stash/Standing/Vouch/Capital) is the intended v0.2 shape, or whether the 5-source `VoiceSource` (adding Freeholder + Guild) should be restored for v0.3 wiring. The `SignalKindCount=4` locked-const test (types_test.go:102) currently locks the 4-source shape; changing it in v0.3 is a deliberate locked-const update.
-- **Severity**: P1 (design-choice divergence from deliverable, tested and self-consistent, not blocking).
-
-### P2 (nit): Bearers ValidateGenesis remains a no-op
-- **File:line**: `x/bearers/types/types.go:108` (`func ValidateGenesis(bz json.RawMessage) error { return nil }`)
-- **Note**: this is CORRECT per spec — P4-02-01 said "DefaultParams/GenesisState unchanged" (bearers is an EXTENSION, not a new module; v0.1's bearers ValidateGenesis was a no-op and the extension adds types, not genesis state). The A-212 upgrade was scoped to NEW modules. Recording as a P2 nit for completeness, not a defect. No action needed.

-## 4. Grill Binding Decisions Verification (G-001..G-010)
-
-| ID | Decision | Status | Evidence |
-|---|---|---|---|
-| **G-001** | Correct v0.1 baseline test count: 53 tests / 11 files (not 48) | **APPLIED** | PROJECT.md D-033 line 111: "53 tests across 11 test files (corrected per G-001; not 48)"; RESEARCH.md line 20: "53 tests across 11 test files (not 48)"; RESEARCH.md line 575: "53 tests, 11 files, zero deps". No "48" reference remains as a v0.1 baseline claim. |
-| **G-002** | Lexicon assertion tests are NEW in v0.2 (v0.1 has zero); firewall is new work, not inherited | **APPLIED** | RESEARCH.md lines 16-20: "v0.1 is lexicon-clean in practice but has **zero** lexicon test files... The lexicon assertion tests are NEW in v0.2"; PROJECT.md D-032 line 110: "lexicon assertion tests are NEW in v0.2 — v0.1 is lexicon-clean in practice but has NO lexicon test firewall". Code: `lexicon/lexicon.go` + `lexicon_meta_test.go` are new in v0.2; zero lexicon test files exist on `main`. |
-| **G-003** | By-ID-string inter-module refs (A-203) enforced as a TESTED invariant in P1-01-02 | **APPLIED** | `x/window/types/types_test.go:437` `TestG003NoCrossModuleStructImportsInProduction` scans every non-test `.go` under `x/` with `go/parser` (ImportsOnly) and asserts no production file imports a foreign `x/<module>/types` package. Test passes (verified: `go test -run TestG003... -v` → PASS). Independent grep confirms zero cross-module struct imports in production code. |
-| **G-004** | Lexicon meta-test scaffolding moved from P5 to P1 Wave 3 (new task P1-04-02); P5-01-01 EXTENDS it | **APPLIED** | `lexicon_meta_test.go` exists at repo root with `TestLexiconMetaNoBannedTermsInX`, `TestLexiconMetaSelfTestTable`, `TestLexiconMetaBannedTermsCount`, `TestLexiconMetaNoFalsePositiveOnOpenYield`. Package doc (line 1-15) states "the durable firewall created in v0.2 P1 Wave 3; P5-01-01 EXTENDS it rather than recreating it." All 4 meta-tests pass. |
-| **G-005** | One `x/pact` module with `PactType` enum + 6 per-type execute-entry structs (A-207), NOT six micro-modules | **APPLIED** | PROJECT.md D-027 line 105: "**one `x/pact` module** with a `PactType` enum... NOT six micro-modules". Code: single `x/pact/types/types.go` with `PactType` enum (6 values) + 6 `Execute*` methods on `*Pact` (`ExecutePause`, `ExecuteGround`, `ExecuteStance`, `ExecuteCover`, `ExecuteStandRegistry`, `ExecuteHubAPI`). No `x/pactpause`, `x/pactground`, etc. dirs exist. |
-| **G-006** | `go.mod` is read-only in v0.2 (zero deps, A-201); any change is an escalation | **APPLIED** | `git diff main..oy/milestone/v0.2-mesh -- go.mod` is **EMPTY**. PERSONAS.md lines 9, 33, 65, 83, 114 all state "go.mod is read-only in v0.2 (G-006)". No persona may modify it. |
-| **G-007** | `x/pact`/`x/partner`/`x/bond`=backend-engineer; `x/window`/`x/stand`/`x/guild`/`x/council`/`x/satellite`/`x/forex`/`x/bearers`=cosmos-engineer | **APPLIED** | PERSONAS.md line 65 (backend territory): "`x/pact/**`, `x/partner/**`, `x/bond/**`"; line 83 (cosmos territory): "`x/satellite/**`, `x/council/**`, `x/window/**`, `x/stand/**`, `x/guild/**`, `x/forex/**`, `x/bearers/**` (Cosmos-convention-mirroring modules per G-007; `x/pact`/`x/partner`/`x/bond` are backend-engineer's)". Lines 109-111 reiterate the split. No overlap remains. |
-| **G-008** | Genesis schema (`genesis.go`)=data-engineer; genesis test assertions (`*_test.go` incl `genesis_test.go`)=security-engineer | **APPLIED** | PERSONAS.md line 14 (data-engineer): "Owns genesis SCHEMA only (G-008); test assertions are security-engineer's"; line 17: "does NOT own *_test.go files (G-008)"; line 41 (security-engineer): "owns ALL *_test.go files including genesis_test.go (G-008)"; line 71 (data-engineer territory): "`x/**/types/genesis.go`, `x/**/genesis.go` (excludes `*_test.go` per G-008)"; line 89 (security-engineer territory): "all test files per G-008". Code: `genesis.go` files present in 7 modules; `genesis_test.go` present in window/stand/bond; all `*_test.go` use `package types_test` (external test package, security-engineer convention). |
-| **G-009** | Self-test table in lexicon meta-test (synthetic string per banned term) | **APPLIED** | `lexicon_meta_test.go:83` `TestLexiconMetaSelfTestTable` — builds a synthetic string per banned term (10 terms: bank, deposit, interest, yield, currency, dollar, euro, account, savings, depositor) and asserts each triggers detection. Test passes. Also `TestLexiconMetaBannedTermsCount` asserts exactly 10 terms configured. |
-| **G-010** | P5-01-03 reconciles ROADMAP.md tag-line narrative (v0.0.x vs v0.1.x) | **N/A** (P5 task, out of P1-P4 review scope) | G-010 is explicitly a P5-01-03 task (ROADMAP tag-line reconciliation). P1-P4 execution phases do not touch ROADMAP.md. The PLANS.md P5-01-03 task description (line 249) still carries the G-010 obligation. Correctly deferred to P5. |

-## 6. Overall Verdict
-
-### **APPROVE WITH P1+ FLAGS**
-
-The v0.2 (The Mesh) milestone P1-P4 execution work is **shippable**.
-
-**Rationale:**
-- All P1-P4 must-have checklists are met (verified per phase in §5).
-- All 13 locked consts/enums are correct (Window 4, Stand 9, Guild 0, Pact 6, Partner 4, Council 3, MissionLock false in pact+council, Bond 800/0, Forex ≥0, Satellite 5+4).
-- All ValidateGenesis ID-uniqueness checks present (A-212 upgrade applied to all 9 new modules; bearers extension correctly exempt).
-- `go build ./...` and `go test ./...` green across all 25 packages (15 v0.1 + 10 v0.2) — no regression.
-- Coverage ≥80% on all 10 new/extended packages (floor 95.9%, 8 of 10 at 100%).
-- Lexicon firewall green (zero banned terms in any `x/**/*.go`); G-002 firewall is new and operational.
-- G-003 by-ID-string invariant tested and green (zero cross-module struct imports in production).
-- go.mod unchanged (G-006 verified — `git diff` empty).
-- 9 of 9 applicable grill binding decisions applied (G-010 is P5, N/A for this scope).
-- Mission Lock and Bond Clamp invariants are compile-time consts + tested firewalls.
-
-**P1+ flags (2) for post-hoc review — do NOT block the milestone ship:**
-1. Council `Proposal`/`ProposalStatus`/`VoteOption` lifecycle enums absent (P3-01-01 deliverable drift; must-haves met; recommend adding for v0.3 live governance wiring).
-2. Council `VoiceSource`→`SignalKind` (4 sources Stash/Standing/Vouch/Capital, not 5 with Freeholder/Guild) (P3-01-01 deliverable drift; defensible design choice; locked-const test currently locks the 4-source shape; confirm intended for v0.3).
-
-These are design-shape divergences in a single module's non-must-have lifecycle types. They do not affect the Mission Lock firewall, the locked consts, the lexicon firewall, the by-ID-string invariant, coverage, or any must-have. The orchestrator should review them post-ship and decide whether v0.3 restores the full Proposal/VoteOption lifecycle and the 5-source VoiceSource.
-
-**P0 fixes auto-applied: 0**
-**P1+ flags: 2** (both in x/council/types)
-**P2 nits: 1** (bearers ValidateGenesis no-op — correct per spec, no action)
-**Grill decisions applied: 9 APPLIED + 1 N/A (G-010 is P5) = 9 of 9 applicable**

+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).
+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 Spec — spec-v3 (net new only)
+Owner: <product owner>
+Status: draft
+Ingested as: oy-spec
+
+> This spec contains ONLY net new requirements, constraints, and decisions for v0.7+ scope. Locked-vision baseline (REQ-001..REQ-021), shipped REQs (REQ-022..REQ-045 per `oy-state` §2), Principles [locked], Lexicon [locked], and pre-filled project invariants are NOT restated; they remain in force per vision v3.0 and prior spec revisions. This is the diff against spec-v2.
+
+## 1. Objective
+
+The v0.7 milestone delivers **Fraternal Groups Foundation** — Cover Pools, Chapter Federation, Mutual Aid Bonds, and the Anti-Capture Bill of Rights v0.2 — adapting the 1890–1930 fraternal benefit-society model for borderless digital service [3]. The v0.8+ roadmap layers in **Risk Mitigations + Infrastructure Economics** — Cluster A–E risk register closures, infrastructure underwriting primitives (Relay Fee Schedule, Coverage Standing Bonus, IYB with subordination, USZ classification), Watcher/Voucher compensation, and the Anchor no-Voice clause. Two PO rulings bind this revision: **no subsidies** (Root-Pool operating-expense subsidies and transfer-payment analogs are forbidden), and **Anchor no-Voice** (Anchors — including Sovereign Anchors — receive preferred contract terms only, never governance Voice).
+
+## 2. Vision source
+Vision v3.0 [1]; SPEC-001 `oy-fraternal-groups` v0.2 [3]. All locked commitments remain in force; **no vision amendments proposed**.
+
+## 3. Principles [locked]
+Locked per vision v3.0 §2. Not restated.
+
+## 4. Requirements (net new)
+
+> REQ-001..REQ-021 are locked-vision baseline (in force, not restated). REQ-022..REQ-045 are shipped per `oy-state` §2 (not restated). New REQs continue from REQ-046.

+| REQ-082 | Sybil on Standing — Bayesian prior + distinct counterparties + time decay | §9.2 | High | yes | Bayesian prior weight 10 (§9.2); minimum distinct counterparties 3/10/30; time-decayed Bayesian average penalizes burst-rating; Diversity Bonus × Voucher Weight resists amplification; Watcher attestation on Freeholder transition; 90-day Stash Maturity signal |
+| REQ-083 | Window abuse — 5-property semantics + rate-limit enforcement | §10 | High | yes | Window enforces 5 properties (Scope, Duration, Rate-limit, Audit log, Revoke); one-tap revoke works mid-service; audit log exportable to Holder's Stash at any time; rate-limit enforcement is protocol-layer with Watcher-witnessed violations; Partner abuse triggers Window closure + Partner status review |
+| REQ-084 | Vouching cascade — vouch slashes voucher + Watcher detection | §9.1, §9.4 | Medium | yes | Vouch requires skin-in-the-game — vouchee's Crack slashes voucher's Standing; Freeholder min-counterparties = 10 makes cascade hard to bootstrap; Watcher detection on rapid vouch sequences; Voucher Weight tapers with chain depth |
+| REQ-085 | Norm chilling — Cover opt-in + dispute path + public profile | §4.9 [3] | Medium | yes | Cover opt-in (FR-NORM-4); non-participation MUST NOT deny other mesh products; norms enforced only through dispute path (FR-NORM-2), never unilateral Council; norm violations counted toward §9.4 slashing history (visible reputation consequence); Pool Public Profile must publish Statement if any (FR-CHTR-4 + FR-GLD-11); protocol never enforces SoB content |

+
+| ID | Title | Vision § | Priority | Locked? | Acceptance criteria |
+|----|-------|----------|---------|---------|---------------------|
+| REQ-087 | Cycle defaults — Cover integration + hash-committed order | §16, §11 | Medium | yes | Cover Pool integration with default ranking (SPEC-001 §12.1); Cycle Host order hash-committed (FR-CIRCLE-1); Counsel-mediated dispute path (FR-CIRCLE-4); Circle pauses via Still on default; restarts after resolution |

+
+#### Infrastructure Economics (REQ-092..REQ-097)
+
+| ID | Title | Vision § | Priority | Locked? | Acceptance criteria |
+|----|-------|----------|---------|---------|---------------------|
+| REQ-092 | Relay Fee Schedule (parity with Processors, auto-declining) | §15 | High | yes | Per-packet relay fee for OY-LR / OY-BLE / OY-WiFi-Direct relay operators; paid in Bread from protocol-fee pool; auto-declining on same schedule as Processor share (50→30→20→10%); self-balancing supply (dense zones saturate, sparse zones attract premium) |
+| REQ-093 | Coverage Standing Bonus (supplement Committed Capital, not replace) | §9.1 | Medium | yes | Sustained infrastructure provision (90-day rolling relay uptime, Watcher attestation) counts as a Standing signal; supplements (does NOT replace) Committed Capital (which remains 1+ active Pact OR 60+ day Guild per §9.1); same anti-gaming rules apply |
+| REQ-094 | Infrastructure Yield Bond (with structural subordination) | §17 | Medium | yes | IYB coupon from Root-Pool infrastructure budget; bounded by `CouponCapBps=800`; use-of-proceeds locked to infrastructure build-out; standard IYB for high-density (commercial trade routes, dense corridors); subordinated IYB for transitional USZs (Anchor takes first loss, local fee revenue takes upside); Watcher attestation at deployment + every quarterly audit |
+| REQ-095 | Universal Service Zone classification (no subsidies) | §13 | Medium | yes | USZ designation via Mesh Council vote within bounds; ≥3 criteria (density, strategic value, mission-aligned override); opt-in (zones choose to be USZs); **NO SUBSIDIES** — infrastructure capital sourced EXCLUSIVELY from (a) Anchor pre-commitment, (b) Sovereign Anchor partnerships, (c) subordinated IYB; market decides whether USZ infrastructure is built; **TBD-Z density formula = PO ruling needed (§8)** |
+| REQ-096 | Watcher/Voucher operating-expense compensation (capped) | §7, §19 | Medium | yes | Watcher + Voucher compensation paid from Root-Pool operating budget; capped annually by Mesh Council vote within bounds; NOT from Bond Market fees (avoids fee-maximization race); audited quarterly by Watchers; Counsel = civic contribution, no operating-expense compensation |
+| REQ-097 | Anchor no-Voice clause (Anchor = preferred terms, zero Voice) | §13, §19 | High | yes | Anchors (commercial per §13) — and Sovereign Anchors — receive preferred contract terms only; ZERO Voice in any Council; no Voice transfer to underlying governments or institutions; Pier Selection Index surfaces Anchor reputation; no "no masters" violation, no matter the Anchor's institutional weight |
+
+## 5. Constraints (net new)
+
+> Pre-filled project invariants (14 components, lexicon firewall, Mission Lock non-amendable, etc.) remain in force per spec-v2 and prior revisions; not restated.
+
+Net new for spec-v3:
+
+- **No subsidies.** Root-Pool operating-expense subsidies, transfer-payment analogs, and welfare-state derivatives are **FORBIDDEN**. Capital for infrastructure is sourced exclusively from Anchor pre-commitment underwriting, Sovereign Anchor partnerships, and subordinated Infrastructure Yield Bond structures. *(oy-spec-v3, PO ruling 2026-08-18)*
+- **Anchor no-Voice.** Anchors (per §13) — including Sovereign Anchors — receive preferred contract terms only. **ZERO Voice in any Council.** No Voice transfer to underlying governments or institutions. *(oy-spec-v3, PO ruling 2026-08-18)*
+- **Sovereign Anchors require separate SPEC.** The Sovereign Anchor framework is too infrastructure-scale to fold into oy-spec. Forthcoming SPEC: `oy-sovereign-anchors`. Until that SPEC ships, USZ infrastructure financing via Sovereign Anchor partnerships is **experimental, not load-bearing**. *(oy-spec-v3, PO ruling 2026-08-18)*
+- **Pier-Routed Legal Wrapper is OPTIONAL.** Default stance: no wrapper required. SPEC-001 §8.3 menu is value-add for Chapters/Guilds that want a legal seat, not a requirement. *(oy-spec-v3, per session refactor)*
+
+## 6. Lexicon [locked]
+Locked per vision v3.0 §3. Not restated.
+
+## 7. Milestone intent
+
+- **Current shipped:** v0.6 (Nomad Web UI) — v0.5.6 — COMPLETE [2]
+- **Next: v0.7 — Fraternal Groups Foundation.** Ships REQ-046..REQ-056 (Cover Pool Factory + Cover-Charter + Chapter Federation + Mutual Aid Bond + Cover Claims Voucher + Anti-Capture Bill v0.2) + REQ-057..REQ-066 (architect recommendations Q1–Q10).
+  - *Acceptance:* ≥1 Cover Pool live on testnet with reserve enforcement + Standing gate + category tagging; ≥1 Parent Guild with Chapter in secession-eligible formation with good-standing liens declared at founding; ≥1 Mutual Aid Bond issuance with Cover-Call coupon settlement + use-of-proceeds lock to reserve build-out; Anti-Capture Bill v0.2 reviewed by bonded Counsel; pen-test ≥1 independent third party; high/critical findings remediated.
+- **v0.8 — Risk Mitigations + Infrastructure Economics.** Ships REQ-067..REQ-097 (Cluster A–E mitigations + Relay Fee Schedule + Coverage Standing Bonus + IYB + USZ classification + Watcher/Voucher compensation + Anchor no-Voice).
+  - *Acceptance:* all listed REQs in §4 v0.8+ implemented with regression tests; `oy-state` §3 const firewall extended with `EyeQuorumMin=7`, `AnchorConcentrationCapBps=2000`, `MABCouponMaxAnnualSurplusMultiple=3`, `BondIssuerSurplusCeilings={1×, 2×, 3×}`, `CoolingSecessionCoverActive=21 days`, `CoolingSecessionNonCover=14 days`, `CoverReserveFloorAnnualContribX=1.5`.
+- **Out-of-scope additions for v0.7:**
+  - Sovereign Anchor SPEC (forthcoming; experimental only this milestone per §5)
+  - USZ classification runtime (deferred to v0.8 — depends on Anchor pre-commitment framework)
+  - Pre-existing deferred items per `oy-state` §4 remain deferred (not restated here)
+
+## 8. Open questions (net new)
+
+> Pre-existing PO decisions tracked in `oy-state` §7 remain open unless addressed here.
+
+1. **TBD-X volume threshold** for Stand→Pier-customer boundary escalation (REQ-059). PO recommendation: **$100k annual Pass volume**.
+2. **TBD-Z density formula** for USZ classification (REQ-095). PO recommendation: **<10 Holders per km² AND strategic value ≥ mission score, OR sovereign request, OR mission-aligned override via Mesh Council supermajority**.
+3. **Sovereign Anchor SPEC scope decision.** Separate SPEC (`oy-sovereign-anchors`) or fold into `oy-pier`? PO recommendation: **separate SPEC** — Sovereign Anchors are infrastructure-scale, not legal-wrapper-scale; v0.7 status is *experimental, not load-bearing* per §5.
+4. **Risk mitigation sequencing.** Which of REQ-067..REQ-091 ship in v0.7 vs deferred to v0.8? PO recommendation: **Cluster A + B + C ship in v0.7 (immediate existential + economic + capture risks); Cluster D + E + REQ-092..REQ-097 ship in v0.8 (immune-system + adoption + infrastructure economics).**
+5. **Standing gate enforcement timing.** When does REQ-049 (Cover Pool Standing gate minimums) bind? At Cover Pool Factory runtime (v0.7) or at first live Cover Pool deployment (v0.7 acceptance)? PO recommendation: **Factory runtime — gates are protocol-layer.**
+6. **Watcher/Voucher operating-expense cap.** Mesh Council vote within bounds; PO recommendation: **annual cap = 5% of Root-Pool Bloom, capped at $TBD-W absolute**.
+7. **Anti-Crowding-Out Covenant enforcement code.** The covenant is in §1 / §2.3 of SPEC-001 [3]; does the ciagent codify it as a separate `x/cover` package firewall (parallel to lexicon_meta tests), or embed it in Cover Pool Factory validation? PO recommendation: **separate firewall** — parallel to lexicon meta-tests; rejects any code path that would route Cover-Fees outside contributor-pool semantics.
+8. **MAB use-of-proceeds lock enforcement.** Per REQ-054, MAB proceeds are locked to reserve build-out. Does the ciagent codify this as tagged streaming with auto-Still on misuse detection, or as a Watcher-quorum-only release? PO recommendation: **tagged streaming + Watcher-witnessed release** (defense in depth).
+
+The ciagent logs assumptions if these are unanswered at autonomy=full (decision_confidence_threshold 0.6, clarify_budget 10).

+| v1 | <!-- TODO: date --> | <!-- TODO: docs(spec): initial spec --> | <!-- TODO: summary --> | <!-- TODO: REQ-IDs --> |
+
+---
+
+## Rules (PO <-> ciagent contract)
+
+- **One document each way.** No slides, sidecar notes, or direct edits to
+  generated docs. If you want to change product intent, edit `oy-spec`; if you
+  want to know what the ciagent did, read `oy-state`.
+- **Every REQ the ciagent implements must appear in §4 with acceptance
+  criteria.** Vague criteria -> vague implementation.
+- **Mark a REQ `[locked]`** only if a future spec revision must not change it
+  without an explicit override line in §9. Locked REQs map to const firewalls
+  the ciagent defends with regression tests (listed in `oy-state` §3).
+- **The ciagent regenerates `oy-state` at every milestone ship AND at P0 of the
+  next milestone if `oy-spec` changed since the last `oy-state`.** `oy-state`
+  is authoritative for "what exists"; PROJECT.md is internal working memory.
+- **Before proposing a new REQ in §4, grep `oy-state` §2 (coverage) and §4
+  (deferred).** Re-proposing an existing or explicitly-deferred REQ is a no-op
+  and will be flagged as drift in the next `oy-state` §5.
+- **When §4 or §6 change,** the ciagent regenerates PROJECT/REQUIREMENTS and
+  flags drift. When §3/§5 only change, no regeneration is needed.
+
+## Commit convention (mandatory for `oy-spec`)
+
+- Every commit that modifies `oy-spec` MUST use a Conventional Commit message:
+
+  ```
+  docs(spec): <imperative summary <=72 chars>
+
+  <optional body: what changed in §4/§6 and why; >=1 line per REQ affected>
+  ```
+
+- Examples:
+  ```
+  docs(spec): add REQ-046 governance spam deposit (§4)
+
+  Opens REQ-046 per oy-state §4 deferred item "governance spam deposit".
+  Acceptance: proposal deposit >= 1 Loaf, slashable on spam.
+  ```
+  ```
+  docs(spec): lock REQ-002 fee ceiling — overrideable only via §9
+
+  REQ-002 fee covenant locked per vision §18; any future change requires an
+  explicit §9 changelog override line.
+  ```
+
+- The ciagent will **REJECT** any `oy-spec` commit whose subject does not match
+  `docs(spec): ...`. This makes spec changes grep-able and ties each
+  implementation milestone back to the spec revision that authorized it (via
+  the §9 Changelog row referenced in the commit body).
+- **No squash merges, `fixup!`, or empty commits** for `oy-spec`. Every edit
+  is a real `docs(spec):` commit on the default branch.

+## 5. Drift flags (ciagent -> PO)
+<!-- Differences between oy-spec (latest) and what the ciagent has shipped. -->
+- Lexicon drift: **none**
+- Locked-const drift: **none** (v0.7 const additions are net-new, not amendments)
+- REQ-shape drift: **none** (oy-spec v3 net-new-only diff ingested; REQ-046..REQ-097 added to coverage §2; baseline REQ-001..REQ-045 unchanged)
+- Architecture drift: **planned** — v0.7 introduces a NEW module `x/cover` (Cover Pool Factory + Anti-Crowding-Out firewall + Anti-Capture Bill of Rights). The existing `x/pact` `PactCover` enum value remains as a cross-reference (G-003 by-ID-string). This mirrors the D-039 precedent (`x/hub` split out of `x/pact`'s `PactHubAPI` in v0.3). Will be ratified at GRILL (P0).
+- Spec-version drift: **none** — oy-spec v3 ingested at commit d10bf5e; this state-v2 reflects it.
+
+## 6. Constraints honored (firewall status)
+- **G-003** production import firewall: GREEN (by-ID-string rule at type level; expected_keepers.go shims for keeper cross-calls). v0.7 `x/cover` will follow the same pattern — no production struct imports across `x/<module>/types`.
+- **G-006** go.mod zero-dep: CONTROLLED EXCEPTION — cosmos-sdk v0.50.8 + ibc-go v8.2.1 added in v0.5 (D-055 GRILL-approved, scoped to runtime phases; types/ packages stay dep-free). v0.7 `x/cover` keeper will use the same SDK runtime substrate; no new Go deps expected.
+- **G-028** go.mod diff baseline (v0.6 vs v0.5.0): EMPTY. v0.7 target: EMPTY (no new Go deps; `x/cover` keeper uses existing SDK).
+- **REQ-012** lexicon firewall: GREEN — 3 meta-tests (x/, docs/, web/) all passing. v0.7 will extend to a 4th meta-test if Cover surfaces add user-facing strings (pending RESEARCH); otherwise the existing 3 suffice.
+- **Mission Lock** non-amendable: GREEN — `MissionLockAmendable=false` unchanged; `MissionLockAmendmentRejected` ProposalKind rejected at ValidateBasic (D-064). v0.7 Anti-Capture Bill (REQ-056) extends this: 13 rights non-amendable + non-waivable by any Charter.
+- **Coverage** >=80% on shipped packages: GREEN (v0.5 keepers 82.1%-92.5%; v0.6 web/store 98.1%, web/handlers 89.2%, lexicon_meta_web 100%). v0.7 target: `x/cover` + extensions >=80%.
+- **Feature purity gate** (v0.7): GREEN target — no breaking schema changes to locked-const firewall; G-003 intact; go.mod unchanged.
+- **No subsidies** (v0.7 §5 NEW): GREEN by construction — v0.7 does not introduce any Root-Pool operating-expense subsidy or transfer-payment analog. The Anti-Crowding-Out firewall (D-079, REQ-047/050) rejects any code path routing Cover-Fees outside contributor-pool semantics. Infrastructure financing is out of v0.7 scope (v0.8 REQ-092..095).
+- **Anchor no-Voice** (v0.7 §5 NEW): GREEN by construction — v0.7 does not grant Voice to any Anchor. The Cover Pool Council (REQ-062) = Pool Host + 3 elected Masons + Watcher observer; no Anchor seat. MAB holders (REQ-063) have NO Voice. Sovereign Anchors are out of v0.7 scope (experimental per §5).
+
+## 7. Open PO decisions before next milestone
+<!-- The PO should rule on these in oy-spec §8 or §7 before v0.7 P0. -->
+
+### Resolved this regeneration (D-074..D-081 — PO recommendations accepted as binding at full autonomy)
+| ID | §8 Q | Decision | Rationale | Confidence | Affects |
+|----|------|----------|-----------|------------|--------|
+| D-074 | Q1 (TBD-X) | **$100k annual Pass volume** for Stand→Pier-customer escalation | PO rec accepted; soft upgrade not ban | 0.85 | REQ-059 (v0.7/P5) |
+| D-075 | Q2 (TBD-Z) | **<10 Holders/km² AND strategic value ≥ mission score, OR sovereign request, OR Mesh Council supermajority** | PO rec accepted; formula locked for v0.8 USZ | 0.80 | REQ-095 (v0.8) |
+| D-076 | Q3 (Sovereign Anchor SPEC) | **Separate SPEC `oy-sovereign-anchors`**; experimental, not load-bearing v0.7 | PO rec accepted; infrastructure-scale ≠ legal-wrapper-scale | 0.85 | §5 constraint (v0.7) |
+| D-077 | Q5 (Standing gate timing) | **Factory runtime** — gates are protocol-layer | PO rec accepted; gates bind at x/cover Factory, not first live Pool | 0.88 | REQ-049 (v0.7/P1) |
+| D-078 | Q6 (Watcher/Voucher cap) | **Annual cap = 5% of Root-Pool Bloom**; absolute $TBD-W deferred to v0.8 | PO rec accepted; 5% Bloom ruled now, absolute cap later | 0.82 | REQ-096 (v0.8) |
+| D-079 | Q7 (Anti-Crowding-Out firewall) | **Separate `x/cover/firewall` package + `lexicon_meta_cover`-style meta-test** (defense in depth) | PO rec "separate firewall" accepted; runtime subpackage rejects code paths + meta-test rejects doc drift | 0.84 | REQ-047/050 (v0.7/P1) |
+| D-080 | Q8 (MAB use-of-proceeds) | **Tagged streaming + Watcher-witnessed release** (defense in depth) | PO rec accepted; tagged streaming auto-Stills on misuse, Watcher witnesses release | 0.85 | REQ-054 (v0.7/P4) |
+| D-081 | Q4 (Risk mitigation sequencing) | **§7 authoritative** — v0.7 ships REQ-046..066 only; Cluster A+B+C are v0.8 | PO rec overridden by §7 acceptance text; §7 is the milestone contract | 0.90 | v0.7 scope (all REQ-046..066) |
+
+### Remaining open (post-v0.7 — for v0.8 P0)
+1. **$TBD-W absolute Watcher/Voucher cap** — deferred to v0.8 REQ-096 (D-078 partial ruling).
+2. **Sovereign Anchor SPEC scope** — `oy-sovereign-anchors` to be authored by PO before v0.8 P0 (D-076).
+3. **v0.8 Cluster A–E sequencing within v0.8** — which of REQ-067..REQ-097 ship in v0.8 P1..PN? PO should pick a subset or rule "all 31 in v0.8".
+4. **Pen-test third party** — v0.7 §7 acceptance requires "pen-test ≥1 independent third party"; at full autonomy with no external third party available, the ciagent will run a self-administered adversarial review (ci-griller persona) and log this as an assumption unless the PO rules otherwise before P6.
+5. **`oyd` daemon** — still no `app.go`/`cmd/oyd`; v0.7 Cover Pool "live on testnet" = simtest-grade keeper runtime. PO should decide whether v0.8 starts the daemon or continues simtest-only.
+6. **SignalKind 4->5 expansion** — still deferred to v0.8+ governance vote (not v0.7 scope).
+
+## 8. Build/test status
+- `go build ./...`: GREEN (baseline confirmed 2026-08-19 on main @ d10bf5e)
+- `go test ./...`: GREEN (all packages; v0.5 keepers + v0.6 web + lexicon meta-tests all passing)
+- Coverage: all shipped keeper packages >=80%; web packages >=89%
+- Lexicon meta-tests: 3/3 GREEN (x/, docs/, web/)
+- Last green commit: d10bf5e (docs(spec): v3 net-new-only)

+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).

+//
+// 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

+//     §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

+//	SignalKind with 4 sources (Stash/Standing/Vouch/Capital). The 4-source
+//	shape is a defensible design refinement:
+//	  - 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 per REQ-005), which the spec's VoiceSource list
+//	    omitted. Adding Capital corrects the spec to match vision §9.1's
+//	    four-signal definition (REQ-005: "Four Freeholder signals locked").
+//
+//	The 4-source shape matches REQ-005 exactly. The spec deliverable text
