+## 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 |
+|-------|-------|--------|-----|

The v0.3 OYSATLink (surveillance-resistant=true locked) and OYQRCode (one-shot consumed flag) become the handler state objects. Key mesh-specific invariants: (1) OY-QR is one-shot — MsgConsumeOYQR flips consumed BEFORE the transfer effect (replay rejected idempotently, A-521); (2) the surveillance-resistant const is a runtime invariant — the handler must NOT emit geolocation or sender physical location (simtest asserts the event set has NO geolocation fields, a negative test); (3) the BearerTransport interface gains a store-backed impl (the keeper acts as the transport in simtest; no hardware/RF dep, D-054). Hardware integration is explicitly deferred. mesh-engineer is phase-specific (P2 only) — outside P2 the bearer transport territory reverts to backend-engineer.

-> This file supersedes the v0.4 PERSONAS.md for the v0.5 milestone. v0.5 is a
-> **feature** milestone (D-054): 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. This is
-> NOT mainnet — D-020 continues to govern network deployment; runtime =

->
-> The active roster is **backend-engineer + lead-developer + security-
-> engineer (REACTIVATED) + cosmos-engineer (REACTIVATED) + mesh-engineer
-> (REACTIVATED, P2 phase-specific)**. The v0.3 docs personas (frontend-
-> engineer, docs-writer) are deactivated because v0.5 has no docs-content
-> work (the docs site is complete from v0.3; the docs build CI is complete
-> from v0.4). data-engineer is reactivated as a P4-phase-specific persona
-> for the hub custody state (in-memory test store only; removed after P4).
-> ci-security-auditor is default off; activate in P8 for the final audit.
->
-> cosmos-sdk is now a load-bearing dependency (D-055 GRILL-approved
-> controlled exception to G-006); go.mod gains cosmos-sdk v0.50.x +

-## Constraints Carried Forward
-
-- **G-003 production firewall intact**: keeper-to-keeper cross-module calls use `expected_keepers.go` interface shims (ibc-go convention), NOT struct imports of `x/<module>/types`. The by-ID-string rule is preserved at the type level. Test-only cross-package imports remain exempt (the G-003 test exemption, used by REQ-030 in v0.4; simtest may import multiple `x/*/keeper` packages to wire shims).
-- **G-006 controlled exception (D-055)**: `go.mod` gains `cosmos-sdk v0.50.x` + `ibc-go v8.x` (GRILL-ratified). Scoped to runtime phases P1..P7; P0 + P8 stay dep-neutral where possible. `types/` packages gain `sdk.Msg` imports for `Msg*` types (isolated in `types/msg_*.go`); invariant/lexicon tests stay stdlib-only and green. Exact version pin is A-504 (planner/GRILL confirms).
-- **Locked-const invariants unchanged**: v0.5 ADDS `ProposalKind` (4) / `ProposalStatus` (5) / `VoteOption` (4) enums to `x/council/types` (AUDIT §193 P1-1 promotion, D-060) but does NOT change existing locked consts — `CouponCapBps=800` / `CouponFloorBps=0` (D-028), `BearerTypeCount=6`, `PartnerTierCount=4`, `MissionLockAmendable=false`, `SignalKindCount=4` (P1-2 defensible; v0.4 `TestSignalKindShapeIntentional` stays green), `BridgeStatusCount=4`, `ExitStatusCount=5`, `ServiceKindCount=4`, `HubServiceCount=3`, `CouncilKindCount=3`, etc. The REQ-030 cross-const test (`hub.LendingCouponCapBps==bond.CouponCapBps`) stays green.
-- **Lexicon firewall stays green**: the `lexicon_meta_test.go` (x/**/*.go) + `lexicon_meta_docs_test.go` (docs) automatically cover the new `keeper/`, `msg_server.go`, `simtest/` files. The new `Msg*` struct names are the lexicon surface — AVOID "deposit" in `x/hub` custody message names (use `MsgCustodyReceiveAsset`/`MsgCustodyReleaseAsset`, A-542); "coupon" not "interest"/"yield" in `x/bond`; "session"/"frame" safe in `x/bearers`; "veto" safe in `x/council`. Per-module lexicon assertions added to each new `keeper/` package.
-- **Simtest NOT mainnet (D-054)**: handlers exercised against in-memory `sdk.Context` + dbm in-memory store; no real IBC light clients, no real MPC, no real bearer hardware, no real DEX venues, no real Watcher attestations (all stubbed). The simtest does NOT assert front-running safety (out of scope for simtest-grade runtime; the CLOB handler is documented as NOT front-running-safe for mainnet, a Year-3+ concern).
-- **≥80% coverage on runtime packages (D-033 carries forward)**: every `keeper/msg_server.go` + simtest must hit the bar; table-driven handler tests per `Msg*`.

-## Planner-Escalation Items (low-confidence assumptions, surfaced through the normal decision flow)
-
-These are NOT auto-decided; the planner must resolve them before the corresponding phase lands:
-
-1. **A-504** — cosmos-sdk / ibc-go version pin (proposed: cosmos-sdk v0.50.x + ibc-go v8.x; alternative: ibc-go v10 IBC-v2/Eureka). GRILL review. Confidence 0.78.
-2. **A-562** — bond CLOB match above 800 bps: REJECT (fails closed, proposed) vs CLAMP-with-refund (D-057 says "clamp"). Resolve before P6. Confidence 0.70.
-3. **A-572** — `MissionLockAmendment-Rejected` ProposalKind: reject at `ValidateBasic` (proposed, the message never reaches the handler) vs propose-then-fail (record Pending → auto-transition Failed with event). Resolve before P7. Confidence 0.80.
-4. **A-574** — Watcher Veto quorum value (proposed default: 6, matching REQ-004 6-of-9). Resolve before P7. Confidence 0.75.

-## Removal Notes
-
-- frontend-engineer and docs-writer were deactivated in v0.4 (no docs-content phase); they remain deactivated in v0.5 for the same reason (the docs site is complete from v0.3; the docs build CI is complete from v0.4). They will reactivate in v0.6+ if docs content is restructured or i18n is added.
-- cosmos-engineer, security-engineer, and mesh-engineer were deactivated in v0.3/v0.4 (lower Cosmos-convention / invariant density, no bearer hardware runtime); they are REACTIVATED in v0.5 because cosmos-sdk is now load-bearing (D-055), the runtime introduces new security-critical invariant surfaces (CustodyKeyring, CLOB clamp, IBC replay, Mission-Lock const firewall), and the bearer transport gets live handlers (P2).
-- data-engineer is reactivated as a P4-phase-specific persona (hub custody state, in-memory test store only) and removed after P4. This mirrors the v0.3 genesis-schema pattern but scoped narrowly to the P4 custody store.
-- ci-security-auditor is default off; activate in P8 for the final audit + feature purity gate.

+1. **`x/cover` module skeleton** — `x/cover/types/types.go` (CoverPool, CoverFeeTag, CoverCategory, CoverCategoryPhase structs + locked consts), `x/cover/types/expected_keepers.go` (StandingKeeper, WatcherKeeper, BondKeeper, StillKeeper interfaces — G-003 shims), `x/cover/types/msg_cover.go` (MsgLaunchCoverPool, MsgRouteCoverFee, MsgFileCoverCall — `sdk.Msg` impls with ValidateBasic), `x/cover/keeper/keeper.go` (store-backed), `x/cover/keeper/msg_server.go` (one handler per Msg*), `x/cover/keeper/firewall.go` (Anti-Crowding-Out firewall enforcement), `x/cover/module.go` (AppModule + RegisterServices + MsgServer() accessor). Layout mirrors `x/hub/` (D-039 precedent).
+2. **Anti-Crowding-Out firewall (D-079)** — `x/cover/firewall/` subpackage with `CheckCoverFeeRouting(path) error` that rejects any code path routing Cover-Fees outside contributor-pool semantics. Called at the start of every `MsgRouteCoverFee` handler. PLUS `lexicon_meta_cover/` meta-test (4th lexicon meta-test, mirrors `lexicon_meta_web/` pattern) scanning `x/cover/**` docstrings + `x/cover/firewall/**` for doc drift. Defense in depth: runtime rejects code path, meta-test rejects doc drift.
+3. **Reserve floor 1.5× (REQ-047 locked)** — `CoverReserveFloorAnnualContribX = 1.5` const in `x/cover/types`. `MsgRouteCoverFee` handler invokes `checkReserveFloor(ctx, poolID)`; if `pool.ReserveAnnualContribRatio < 1.5`, REJECT routing AND emit `PoolBelowFloor` event that triggers auto-pause for subsequent routings until reserve replenished. Below-floor auto-pause = the handler sets a `PoolPaused bool` on the CoverPool; subsequent `MsgRouteCoverFee` handlers reject while paused.
+4. **Standing gate minimums (REQ-049 locked, D-077)** — `CoverStandingGateTrusted = 4.0` + `CoverStandingGatePreferred = 4.5` consts in `x/cover/types` (cross-documented to `x/standing.BucketTrusted`/`BucketPreferred`). `MsgLaunchCoverPool` handler invokes `StandingKeeper.GetStandingBucket(hostReachID, category)` for each category the Pool covers; if any category's gate is below the locked minimum (Trusted 4.0 for Travel, Preferred 4.5 for Health-MCS), REJECT the launch. Gate binds at Factory runtime (D-077). Pool MAY tighten (a `PoolStandingGate` Params field ≥ protocol minimum); NEVER loosen (the const floor).
+5. **Cover-Fee category tagging (REQ-050 locked)** — `CoverFeeTag` struct in `x/cover/types` (`{GrainAmount int64, CategoryTag string, PoolID string}`). `MsgRouteCoverFee` handler validates the tag against the Pool's allowed categories; category-mismatch → REJECT (FR-COVER-11). Pool-level fungibility preserved for net-reserve accounting.
+6. **Factory runtime (REQ-046)** — `MsgLaunchCoverPool` handler: validates reserve floor (REQ-047), validates Standing gate per category (REQ-049), validates category is in an allowed phase (REQ-065 staging — **D-086: P1 Factory is functional for Phase-2 categories ONLY** [Travel/HealthMCS/IncomePause]; `FactoryAllowedPhases` Params field is set to `[Phase2]` only in P1; Phase3/Phase4 categories are REJECTED in P1. P2 extends `FactoryAllowedPhases` to `[Phase2, Phase3, Phase4]` with full staging), witnesses Cover-Charter (REQ-052 — **D-090(1): Charter types + `RightID` + 13 `Waivable*` consts + `RightIsWaivable()` + `ValidateBasic` gate land in P2, NOT P1**; P1 Factory accepts a Charter hash placeholder only, with no `WaivedRights` field validation until P2). Watcher attestation pipeline: `WatcherKeeper.Attest(poolID, launchPayload)` called at launch; stubbed in simtest.
+7. **Simtest** — `x/cover/keeper/msg_server_simtest_test.go` exercising: (a) successful Pool launch with valid Standing + reserve; (b) rejected launch below Standing gate; (c) rejected launch below reserve floor; (d) rejected Cover-Fee routing with category mismatch; (e) auto-pause on below-floor + recovery on reserve replenishment; (f) firewall rejection of an out-of-pool routing path; **(g) D-086: rejected out-of-phase category launch (Phase 3 category rejected in P1 because only Phase 2 is allowed)**.
+8. **Lexicon + locked-const regression** — `x/cover/types/types_test.go` asserts the 4 new consts + lexicon assertion (no banned terms in `x/cover/**` — "Cover", "Cover-Fee", "Cover Call", "Cover-Charter" are the lexicon-clean names; NOT "insurance", "premium", "claim", "policy" per **D-088: `lexicon_meta_cover` uses a new `lexicon.CoverBannedTerms()` helper** [scoping the 4 Cover-specific terms to the Cover surface, avoiding false positives in non-Cover modules where "claim" is a common English word]). The `lexicon_meta_cover/` meta-test is the 4th lexicon firewall. **D-088(3) optional cleanup: replace `x/pact` "insurance-like" docstrings (`x/pact/types/types.go:36,158`) with "Cover-like" as a P1 doc-fix** (low-risk, no behavior change, removes latent lexicon debt).
+9. **Coverage ≥80%** on `x/cover/types` + `x/cover/keeper` + `x/cover/firewall`.
+10. **D-089(1): `StillKeeper` 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. The P1 below-floor auto-pause invokes `StillKeeper.Still(poolID, "below floor")` on the stub.
+
+### P1 Firewall-First Rationale
+
+P1 lands the Anti-Crowding-Out firewall + locked floors + Standing gates BEFORE any Cover surface that could route around them (P2 Charter, P3 Federation, P4 MAB, P5 Bill of Rights). This is the D-044/D-069 firewall-first pattern: the firewall is in place before the content it guards.

+## Phase P2 — Cover-Charter + Pool Governance Hybrid + Category Staging
+
+- **Type**: feat
+- **Tag**: `v0.6.2`
+- **REQs**: REQ-048, REQ-052, REQ-062, REQ-065
+- **Modules**: extends `x/cover` (Charter + governance + staging) + `x/council` (Pool Council seat — no struct change, keeper logic)
+- **Personas**: backend-engineer (Charter + staging types + keeper), security-engineer (Charter validation + governance observer quorum), cosmos-engineer (Msg* + keeper handlers)
+
+### P2 Must-Haves
+
+1. **Cover-Charter (REQ-052 locked) + D-090(1) Bill of Rights types land HERE** — `CoverCharter` struct in `x/cover/types` (`{CharterID, PoolID, StatementOfBeliefsHash []byte, DisputePath string, Gate string, HoldingPeriodDays uint32, HostReachID string, WatcherWitnessHash []byte, Amendments []CharterAmendment, WaivedRights []RightID}`). `MsgSignCoverCharter` handler: signed by Pool Host + witnessed by Watcher. Amendments require Pool supermajority + 7-day cooling + Watcher + Counsel. **Protocol does NOT enforce SoB content** (FR-CHTR-5). **D-090(1) Bill of Rights temporal-gap fix:** `x/cover/types/rights.go` lands in P2 (NOT P5): 13 `RightID` consts + 13 `Waivable*` bool consts (all `false`) + `RightIsWaivable(id RightID) bool` (always returns `false`) + `AntiCaptureBillOfRightsCount = 13` const. The `MsgSignCoverCharter.ValidateBasic` gate rejects any `WaivedRights` element (dual firewall: const + ValidateBasic, mirroring MissionLockAmendable + MissionLockAmendmentRejected). **The 12 enumerated rights + D-085 13th-right candidate (`RightNonParticipationNoDenial`, confidence 0.55) all land in P2.** P5 then adds the *ceremony* surface (Counsel review handler, full Bill-of-Rights simtest cases). **D-090(4): D-085 escalation window tightened to before P2** — lead-developer surfaces D-085 to PO before P2; fallback at P2: log `RightNonParticipationNoDenial` as the 13th right and proceed.
+2. **Reserve ceiling 2.5× (REQ-048 not locked)** — `CoverReserveCeilingAnnualContribX = 2.5` const (the bounded upper limit). Pool Council MAY vote within [1.5×, 2.5×] via a `PoolReserveTarget` Params field. Watcher escalation to 2.5× after 12 months operating history. The 1.5× floor (P1) is NOT tunable. **D-090(3): the `CoverStandingGateTrusted`/`CoverStandingGatePreferred` floor is enforced at BOTH (a) the `MsgLaunchCoverPool` handler AND (b) the `MsgAmendPoolStandingGate` (Params-amendment) `ValidateBasic`** — a Pool must not be able to *store* a below-floor gate even if the launch would reject it. Same dual-check applies to the reserve target (amendment ValidateBasic rejects below 1.5× or above 2.5×).
+3. **Pool governance hybrid (REQ-062 locked)** — `PoolCouncil` struct in `x/cover/types` (`{PoolID, HostReachID, ElectedMasonReachIDs [3]string, WatcherObserverReachID string}`). `MsgElectPoolMason` handler (Pool-eligible Masons elect 3). `MsgVoteCoverCall` handler: majority required with Watcher observer present. **No Anchor seat** (§5). No MAB-holder seat (REQ-063 — lands in P4 but the governance struct excludes them now).
+4. **Category staging (REQ-065 locked)** — `CoverCategoryPhase` enum in `x/cover/types` (`Phase2`/`Phase3`/`Phase4`). `CoverCategory` enum (`Travel`/`HealthMCS`/`IncomePause`/`EquipmentLoss`/`LifeBurial`/`RoadSide`/`CyberSkimming`/`GuildInternalMutualAid`). Phase 2 = Travel + HealthMCS + IncomePause; Phase 3 = EquipmentLoss + LifeBurial + RoadSide; Phase 4 = CyberSkimming + GuildInternalMutualAid. **D-086: `FactoryAllowedPhases` Params field extended from P1's `[Phase2]` to `[Phase2, Phase3, Phase4]`** with full staging rejection of out-of-phase launches.
+5. **Simtest** — (a) successful Charter signing + Watcher witness; **(b) D-090(1) Charter with `WaivedRights` non-empty → REJECTED at ValidateBasic**; (c) Charter amendment with 7-day cooling + supermajority; (d) Pool Council election (3 Masons); (e) Cover Call vote with Watcher observer present (succeeds) + absent (rejects); **(f) D-086 Factory rejects out-of-phase category launch (Phase 4 category when only Phase 2/3 allowed)**; (g) reserve ceiling escalation after 12-month age check; **(h) D-090(3) Pool Standing gate amendment below floor → REJECTED at ValidateBasic**.
+6. **Lexicon + locked-const regression** — `x/cover/types/types_test.go` extended with the ceiling + phase + category consts + `AntiCaptureBillOfRightsCount=13` + 13 `Waivable*` consts all false + `RightIsWaivable` always false. Lexicon assertion on new Msg* names.
+7. **Coverage ≥80%** on the extended `x/cover` surface.

+## Phase P3 — Guild Charter + Chapter Federation + Household/Confederation + Disclaimer
+
+- **Type**: feat
+- **Tag**: `v0.6.3`
+- **REQs**: REQ-051, REQ-053, REQ-057, REQ-058, REQ-061
+- **Modules**: extends `x/guild` (Parent/Chapter + secession terms + liens + Household + Confederation) + `x/stand` (Household/Confederation keeper logic)
+- **Personas**: backend-engineer (Guild extension + keeper), security-engineer (lien bounding + secession cooling consts), cosmos-engineer (Msg* + keeper handlers)
+
+### P3 Must-Haves
+
+1. **Guild Charter + Common Bond (REQ-051 locked)** — extend `x/guild/types.Guild` with `CommonBondHash []byte` + `PublicProfile GuildPublicProfile` fields. `GuildPublicProfile` struct (`{BondSummary string, Disclaimers []string, MasonCount uint32_or_Private bool, PierWrapperID string}`). `MsgCreateGuild` handler (extended): Common Bond declared + hash-pinned at creation; Public Profile published. `MasonCount` is either a count or a `"private"` sentinel.
+2. **Chapter Federation (REQ-053) + D-087 PierCarriesVoice const** — extend `x/guild/types.Guild` with `ParentGuildID string` (empty for Parent Guilds) + `IsChapter bool` + `SecessionTermsHash []byte` + `GoodStandingLiens []Lien`. `Lien` struct (`{Amount int64, CreditorReachID string, SecuredAtFounding bool}`). `MsgCreateChapter` handler: Parent Guild + Chapter model; Chapter inherits Parent's policies + MAY tighten but NOT loosen. Secession terms coded at founding (a `SecessionTerms` struct: `{CoolingCoverActiveDays uint32, CoolingNonCoverDays uint32, LienAuditRequired bool, CovenantClearanceRequired bool}` — hash-pinned at creation, immutable). Good-standing liens at founding (NOT freely increasable — `SecuredAtFounding=true` liens reject `MsgAddLien`). **D-087: `PierCarriesVoice = false` const in `x/guild/types`** (the 12th locked const per the GRILL-ratified table — FR-VOICE-6: Pier does NOT carry Voice; mission-locked invariant). Chapter retains mesh-level Voice (the const enforces that the Pier wrapper does NOT carry Voice regardless of fiduciary role).
+3. **Household simplified (REQ-057)** — `x/stand` keeper: `IsHousehold(standID)` check (switch on `StandType == StandHousehold`). Household Stands skip the formal-Council requirement. `MsgOneTapExitStand` handler — the dispute path for Household. One-tap exit = the Stand is dissolved + assets returned to the Holder's Stash; no Council vote required.
+4. **Confederation Voice (REQ-058 locked)** — `x/stand` keeper: `GetConfederationVoice(confederationStandID) []Voice` aggregates member-Stand Voice one-per-Stand. Internal bundle delegation via §19 delegation (existing `x/council` Voice mechanics — a `MsgDelegateConfederationVoice` handler). One-Stand-one-Vote: each member Stand gets exactly 1 Voice in the Confederation's aggregate, regardless of size.
+5. **Disclaimer cadence (REQ-061 locked)** — `MsgCreateGuild` + `MsgCreateChapter` + `MsgSignCoverCharter` handlers all surface a jurisdictional disclaimer at every charter signing (a `Disclaimer string` field on each Msg; the handler returns the disclaimer in the response). NOT session-bounded.
+6. **Simtest** — (a) Guild creation with Common Bond hash + Public Profile; (b) Chapter creation with secession terms hash-pinned + good-standing liens; (c) Chapter inherits Parent policy + tightens (allowed) + loosens (rejected); (d) Household one-tap exit; (e) Confederation Voice aggregation (one-per-Stand); (f) disclaimer surfaced at every signing.
+7. **Lexicon + locked-const regression** — `x/guild/types/types_test.go` extended with the cooling consts (`CoolingSecessionCoverActiveDays=21`, `CoolingSecessionNonCoverDays=14`). Lexicon assertion on new Msg* names.
+8. **Coverage ≥80%** on the extended `x/guild` + `x/stand` surfaces.

+## Phase P4 — Mutual Aid Bond + Cover Claims Voucher + Shadow Vouch + MAB Seniority
+
+- **Type**: feat
+- **Tag**: `v0.6.4`
+- **REQs**: REQ-054, REQ-055, REQ-060, REQ-063
+- **Modules**: extends `x/bond` (MAB), `x/cover` (Cover Claims Voucher + MAB seniority waterfall), `x/standing` (Shadow vouch weight + slash reason)
+- **Personas**: backend-engineer (MAB + Voucher + Shadow vouch types + keeper), security-engineer (MAB use-of-proceeds lock + Voucher slashing + Shadow vouch const), cosmos-engineer (Msg* + keeper handlers)
+
+### P4 Must-Haves
+
+1. **Mutual Aid Bond (REQ-054 locked)** — `MAB` struct in `x/bond/types` (anonymous embed of `Bond` + `CouponKind CouponDenom` + `AnnualSurplusAtIssuance int64` + `UseOfProceedsTag string`). `CouponDenom` enum (`CouponDenomCoverCall`/`CouponDenomMutualAidCredit`/`CouponDenomBread` — the last exists ONLY to be rejected at `ValidateBasic` with "FR-MAB-3: MAB coupons NEVER Bread", mirroring `MissionLockAmendmentRejected`). `MABIssuanceCeilingAnnualSurplusMultiple = 3` const in `x/bond/types`. `MsgIssueMAB` handler: `checkMABIssuanceCeiling(ctx, poolID, newPrincipal)` asserts `sum(issuedMABPrincipal) + newPrincipal <= 3 × AnnualSurplus` (re-check at every issuance). Coupon rate bounded by `CouponCapBps=800` (existing locked const — no new const, cross-const test extends).
+2. **D-080 tagged streaming + Watcher-witnessed release** — `UseOfProceedsTag` field locked to `"reserve_build_out"` (a const `MABUseOfProceedsReserveBuildOut`). `MsgDebitMABProceeds` handler: checks destination account is the Pool's `ReserveAccount`; else invokes `StillKeeper.Still(poolID, "MAB misuse")` for auto-Still. `MsgWitnessMABProceedsRelease` handler: requires Watcher quorum (6-of-9, `x/watcher/types/types.go:23` `Quorum=6`) before proceeds move from tagged staging to reserve. Watcher attestation at deployment + quarterly audit (a `MsgWatcherAttestMAB` handler).
+3. **Cover Claims Voucher (REQ-055) + D-090(2) cold-start fix** — `CoverClaimsVoucher` struct in `x/cover/types` (`{VoucherReachID string, PoolID string, BondAmount int64, BondMultipleAvgCall uint32}`). `CoverClaimsVoucherBondMultipleAvgCall = 10` const. **D-090(2): `bond = max(CoverClaimsVoucherBondMultipleAvgCall × avgCallSize, MinimumVoucherBond)` where `MinimumVoucherBond` is a Params field with a non-zero default** — the cold-start fallback when no Calls have been filed yet (avg = 0 → bond = MinimumVoucherBond, NOT zero). `MsgRegisterCoverClaimsVoucher` handler: bonds the Voucher. `MsgFileCoverCall` handler: assigns a Call to a Voucher; **no self-adjudication** (FR-CPCV-2) — rejects if `voucherReachID == claimantReachID`. Slashing via existing `x/standing.Slash` struct with new `SlashReasonFraudulentCoverCall` const — cross-Pool applicability (the slash drops the Voucher's Standing bucket, disqualifying them from other Pools). Bounded earnings (a `MaxVoucherEarningsPerCall` Params field).
+4. **Shadow vouch 50% weight (REQ-060 locked)** — extend `x/standing/types.Vouch` with `IsShadow bool` field. `ShadowVouchWeightMultiplier = 0.5` const in `x/standing/types`. Modify `GetVoucherWeight` to apply the multiplier as a post-step: `if isShadow { weight *= ShadowVouchWeightMultiplier }`. The const makes the 0.5× mission-locked (REQ-060 locked) and regression-testable. New test `TestShadowVouchWeight` in `x/standing/types/types_test.go`.
+5. **MAB holder seniority no-Voice (REQ-063 locked)** — `PoolDissolutionWaterfall` function in `x/cover/keeper`: returns `[{Tier: "CoverFeeContributors", ...}, {Tier: "MABHolders", ...}, {Tier: "BreadHolders", ...}]` (FR-MAB-4 seniority chain). MAB holders excluded from the Pool Council voice set (the `PoolCouncil` struct from P2 already excludes them; P4 adds the waterfall + a `MsgDissolveCoverPool` handler that invokes the waterfall). MAB holders have NO Voice in dissolution decisions.
+6. **D-089(2): `x/bond → x/cover` CoverKeeper reverse edge** — `x/bond/types/expected_keepers.go` gains a `CoverKeeper` interface (`GetPoolReserveAccount(poolID) string`) used by the `MsgDebitMABProceeds` handler to validate the destination. No import cycle (interface only). Documented in ARCHITECTURE.md v0.7 dependency map.
+7. **D-089(1): `StillKeeper` simtest stub** — the MAB auto-Still hook (`MsgDebitMABProceeds` misuse → `StillKeeper.Still`) is satisfied by a simtest-local stub (test-only, G-003 exempt). `x/still` is NOT extended this milestone.
+8. **Simtest** — (a) MAB issuance with valid Cover-Call coupons; (b) MAB issuance rejected with Bread coupons (FR-MAB-3); (c) MAB issuance rejected above 3× annual surplus ceiling; (d) tagged streaming misuse → auto-Still; (e) Watcher-witnessed release (quorum present: succeeds; absent: rejects); (f) Cover Claims Voucher registration + bond; **(g) D-090(2) Voucher cold-start: bond = MinimumVoucherBond when no Calls exist**; (h) Cover Call adjudication (no self-adjudication); (i) Voucher slash for fraudulent Call → Standing bucket drop; (j) Shadow vouch 0.5× weight applied; (k) Pool dissolution waterfall (Cover-Fee contributors > MAB > Bread holders).
+9. **Lexicon + locked-const regression** — `x/bond/types/types_test.go` extended with `MABIssuanceCeilingAnnualSurplusMultiple=3` + `CouponDenom` enum count. `x/standing/types/types_test.go` extended with `ShadowVouchWeightMultiplier=0.5`. `x/cover/types/types_test.go` extended with `CoverClaimsVoucherBondMultipleAvgCall=10`. Cross-const test: MAB coupon cap == `CouponCapBps` (extends REQ-030 pattern).
+10. **Coverage ≥80%** on the extended `x/bond` + `x/cover` (Voucher + waterfall) + `x/standing` (Shadow vouch) surfaces.

+## Phase P5 — Anti-Capture Bill of Rights + Secession Cooling + Stand→Pier Boundary + Pier Selection
+
+- **Type**: feat
+- **Tag**: `v0.6.5`
+- **REQs**: REQ-056, REQ-059, REQ-064, REQ-066
+- **Modules**: extends `x/cover` (Anti-Capture Bill of Rights + Pier Selection Index), `x/guild` (secession cooling enforcement), `x/stand` (Stand→Pier boundary const + escalation)
+- **Personas**: backend-engineer (Bill of Rights + secession + Pier types + keeper), security-engineer (Bill of Rights firewall + secession lien audit + Pier Selection Index), lead-developer (D-085 escalation — 13th right identification before P5 lands), cosmos-engineer (Msg* + keeper handlers)
+
+### P5 Must-Haves
+
+1. **Anti-Capture Bill of Rights v0.2 ceremony (REQ-056 locked) + D-090(1) types already in P2** — the `RightID` type + 13 `Waivable*` consts + `RightIsWaivable()` + `AntiCaptureBillOfRightsCount=13` const + the `MsgSignCoverCharter.ValidateBasic` gate ALL landed in P2 (D-090(1) temporal-gap fix). **P5 adds the *ceremony* surface:** the `MsgCounselReviewBillOfRights` handler (the "bonded Counsel review" §7 acceptance criterion — the Counsel's Standing bond is staked; the handler records the review result). P5 also adds the full Bill-of-Rights simtest cases (the P2 simtest covered the ValidateBasic gate; P5 covers the Counsel review + the 13-rights regression test asserting all 13 `Waivable*` consts are `false` + `RightIsWaivable` returns `false` for all 13). The 12 enumerated rights + D-085 13th-right candidate (`RightNonParticipationNoDenial`) are all in P2; P5 does NOT re-declare them.
+2. **Dual firewall (const + ValidateBasic) — ALREADY IN P2** — the `MsgSignCoverCharter.ValidateBasic` gate rejecting `WaivedRights` landed in P2 (D-090(1)). P5's contribution is the Counsel review ceremony + the full regression test suite.
+3. **Secession cooling enforcement (REQ-064 locked)** — `x/guild/keeper`: `MsgInitiateSecession` handler records `secessionStartedAt` + invokes `lienAudit(poolID)`. `MsgCompleteSecession` handler checks: (a) `now >= secessionStartedAt + coolingSeconds` where `coolingSeconds = CoolingSecessionCoverActiveDays*86400` (21d) if the Chapter is Cover-active, else `CoolingSecessionNonCoverDays*86400` (14d); (b) lien-audit-passed; (c) Cover Call / Bond covenant clearance passed. Cooling secured at founding (the `SecessionTerms` from P3 is immutable), NOT reducible. Parent Guild Treasury receives pro-rata Cover-Fee settlement for in-flight Cover Calls (a `ProRataSettlement` function in `x/cover/keeper`).
+4. **Stand→Pier boundary (REQ-059, D-074)** — `StandPierEscalationAnnualPassVolumeCents = 10000000` const in `x/stand/types` (placeholder for $100k in Grain-cents at simtest; the PO ruling D-074 is $100k USD which is converted at the current USD/Grain oracle rate — but no oracle exists in simtest). The handler `MsgEscalateStandToPier` (or a keeper-level `checkStandPierEscalation(standID)` invoked on Pass routing): when annual Pass volume > the const, the Stand is *invited* to Hub API (a `StandPierEligible bool` flag + a `MsgAcceptPierInvitation` handler). Soft upgrade, not a ban — the Stand may decline.
+5. **Pier selection (REQ-066)** — `PierSelectionIndex` struct in `x/cover/types` (`{PierID string, JurisdictionalReliabilityScore float64, FiduciaryRecordHash []byte, IntegrationQualityScore float64, OverallScore float64}`). `MsgSelectPier` handler: Guild Council chooses Pier at formation. `MsgRevokePierSelection` handler: reversible by Cover Pool supermajority + Counsel witness. Mesh maintains the Pier Selection Index (a keeper-level `GetPierSelectionIndex(pierID)` query). **Pier-Routed Legal Wrapper is OPTIONAL** (§5 default-no-wrapper — no code required; a `PierWrapperID string` field on Guild from P3 is optional, empty by default).
+6. **Simtest** — (a) Charter signing with waived rights → REJECT (dual firewall — **already in P2, P5 re-verified**); (b) Charter signing with no waived rights → succeeds; (c) `RightIsWaivable` returns false for all 13 rights; (d) `MsgCounselReviewBillOfRights` ceremony (bonded Counsel staked + review recorded); (e) secession initiation + 21d cooling (Cover-active) + lien audit + covenant clearance + completion; (f) secession rejected before cooling expires; (g) secession rejected with outstanding liens; (h) Stand→Pier escalation at >10M Grain-cents annual Pass volume; (i) Stand declines Pier invitation (soft upgrade); (j) Pier selection by Guild Council; (k) Pier selection revoked by Cover Pool supermajority + Counsel.
+7. **Lexicon + locked-const regression** — `x/cover/types/types_test.go` extended with `AntiCaptureBillOfRightsCount=13` + 13 `Waivable*` consts all false (P2 landed them; P5 adds the full regression suite). `x/stand/types/types_test.go` extended with `StandPierEscalationAnnualPassVolumeCents=10000000`. Lexicon assertion on new Msg* names.
+8. **Coverage ≥80%** on the extended `x/cover` (Bill of Rights ceremony + Pier Index) + `x/guild` (secession) + `x/stand` (Pier boundary) surfaces.

+## Phase P6 — Final Review + Audit + Milestone Ship
+
+- **Type**: final (REVIEW + AUDIT + milestone SHIP)
+- **Tag**: `v0.6.6` (= v0.7 milestone release per D-008)
+- **REQs**: all REQ-046..REQ-066 marked complete
+- **Personas**: lead-developer (review + audit + ship), ci-security-auditor (REACTIVATED — feature purity gate + pen-test), backend-engineer (P1+ fixes if review flags), security-engineer (P1+ fixes if review flags)
+
+### P6 Must-Haves
+
+1. **`ciagent-review`** — multi-persona code review across P1..P5. Reviews all changes in `milestone/v0.7-fraternal-groups`. Auto-applies P0 fixes, flags P1+ for post-hoc review. If P1+ issues found: fix in P6.
+2. **`ciagent-audit`** — reconstruction test (git log matches `.ciagent/` files), `.ciagent/` file discipline, branch hygiene, commit discipline.
+3. **Feature purity gate** — no breaking schema changes to EXISTING locked consts; G-003 production firewall intact; G-006/G-028 go.mod diff EMPTY; lexicon firewall green (4 meta-tests: x/, docs/, web/, cover/). The 11 new locked consts are net-new (not amendments).
+4. **§7 acceptance criteria verified**:
+   - ≥1 Cover Pool live on testnet with reserve enforcement + Standing gate + category tagging (simtest-grade — P1+P2)
+   - ≥1 Parent Guild with Chapter in secession-eligible formation with good-standing liens declared at founding (P3)
+   - ≥1 Mutual Aid Bond issuance with Cover-Call coupon settlement + use-of-proceeds lock to reserve build-out (P4)
+   - Anti-Capture Bill v0.2 reviewed by bonded Counsel (simtest — the Counsel review is a `MsgCounselReviewBillOfRights` handler; "bonded" = the Counsel's Standing bond is staked)
+   - **pen-test ≥1 independent third party** — at full autonomy with no external third party available, run self-administered adversarial review (ci-griller persona) and log as assumption (oy-state §7 remaining-open item 4). The ci-griller red-teams the Anti-Capture Bill + Anti-Crowding-Out firewall + MAB use-of-proceeds lock + secession cooling + Voucher slashing.
+   - high/critical findings remediated (the ci-griller's binding P0 fixes are applied in P6; P1+ flagged for post-hoc review)
+5. **`ciagent-ship` (milestone ship)** — merge `phase/06` → `milestone/v0.7-fraternal-groups` → `main`. Tag `v0.6.6` (= v0.7 milestone release). Create release with full milestone summary. Delete all milestone branches (local + remote).
+6. **Milestone completion** — REQUIREMENTS.md marks REQ-046..REQ-066 complete. ROADMAP.md marks v0.7 complete. Commit `docs(milestone): complete v0.7-fraternal-groups-foundation`. Clear CHECKPOINT.json.

+
+v0.7 is a protocol milestone with NO user-facing UI surface (the v0.6 web UI is complete; v0.7 does not touch `web/`). The user-facing surface for v0.7 is the **simtest** — the `x/cover/keeper/msg_server_simtest_test.go` file is the executable demonstration that a Cover Pool can be launched, a Charter signed, a MAB issued, a Cover Call adjudicated, and a Chapter seceded. The simtest IS the "user-facing surface" for a protocol milestone: it's the artifact a developer reads to understand the Cover Pool lifecycle.
+
+- **CLI flag**: none (no `oyd` daemon exists; D-020 continues). The simtest is run via `go test ./x/cover/keeper/...`.
+- **README quickstart**: the v0.7 milestone adds a section to `docs/reference/` (lead-developer territory, not v0.7 scope — docs-content is deactivated per PERSONAS.md; the ARCHITECTURE.md v0.7 section is the reference). The simtest is the quickstart.
+- **Docs**: `.ciagent/oy/ARCHITECTURE.md` v0.7 section (the component index + cross-component dependencies + locked-const additions) is the developer-facing reference for the Cover Pool surface.
+- **`.feature` Scenario**: the simtest functions are named as scenarios: `TestCoverPoolLaunch_ValidStanding`, `TestCoverPoolLaunch_BelowStandingGate_Rejected`, `TestMABIssuance_BreadCoupons_Rejected`, `TestSecession_21DayCooling_CoverActive`, `TestAntiCaptureBill_WaivedRights_Rejected`, etc.
+
+## Happy Path
+
+(MVP/UX CHECK section 2 of 3 — per run.md MVP/UX CHECK gate)
+
+The v0.7 happy path (end-to-end scenario, written BEFORE execute, verified by simtest in P6):
+
+1. **A Guild Council creates a Cover Pool** via `MsgLaunchCoverPool` for the Travel category (Phase 2). The Factory validates: reserve floor 1.5× (REQ-047), Standing gate Trusted 4.0 for the Pool Host (REQ-049), category Travel is in Phase 2 (REQ-065). The Watcher attests the launch. The Pool is live (simtest-grade).
+2. **The Pool Host signs a Cover-Charter** via `MsgSignCoverCharter` with a Statement-of-Beliefs hash, a dispute path, a 30-day holding period, and a Watcher witness. The Charter is distinct from the Guild's governance charter. The protocol does NOT parse the SoB content (FR-CHTR-5). The Anti-Capture Bill of Rights is non-waivable — the Charter's `WaivedRights` field is empty (REQ-056).
+3. **Pool-eligible Masons elect 3 Masons to the Pool Council** via `MsgElectPoolMason`. The Pool Council = Pool Host + 3 elected + Watcher observer. No Anchor seat (§5). No MAB-holder seat (REQ-063).
+4. **Cover-Fees are routed to the Pool** via `MsgRouteCoverFee` with a `CoverFeeTag{CategoryTag: "Travel", PoolID: "pool-1"}`. The Anti-Crowding-Out firewall (D-079) checks the routing path — the fee goes to the Pool's contributor-pool reserve, NOT to Root-Pool operating expenses. The reserve floor check passes (1.5×). The category-tag matches the Pool's allowed categories (FR-COVER-11).
+5. **The Pool issues a Mutual Aid Bond** via `MsgIssueMAB` with `CouponKind: CouponDenomCoverCall`, `PrincipalGrain: 50000000`, `UseOfProceedsTag: "reserve_build_out"`. The issuance ceiling check passes (`sum(existing MAB principal) + 50M <= 3 × AnnualSurplus`). The coupon rate is bounded by `CouponCapBps=800` (8%). The proceeds are tagged for reserve build-out (D-080).
+6. **The MAB proceeds are released** via `MsgWitnessMABProceedsRelease` — the Watcher quorum (6-of-9) witnesses the release. The proceeds move from the tagged staging account to the Pool's reserve account. If the proceeds were routed elsewhere, the auto-Still would fire (simtest tests this in a negative case).
+7. **A Cover Call is filed** via `MsgFileCoverCall` — a Holder files a Cover Call against the Travel Pool. A Cover Claims Voucher is assigned (bond 10× avg Call size). The Voucher is NOT the claimant (FR-CPCV-2 no self-adjudication). The Voucher adjudicates the Call. If the Voucher commits fraud, they are slashed via `x/standing.Slash` with `SlashReasonFraudulentCoverCall` — the Standing bucket drops, disqualifying them from other Pools (cross-Pool applicability).
+8. **A Parent Guild's Chapter secedes** — the Chapter was founded with `SecessionTerms{CoolingCoverActiveDays: 21, LienAuditRequired: true, CovenantClearanceRequired: true}` + a good-standing lien secured at founding. The Chapter initiates secession via `MsgInitiateSecession`. After 21 Mesh-days (Cover-active), the lien audit passes, the Cover Call / Bond covenants are cleared, and the secession completes via `MsgCompleteSecession`. The Parent Guild Treasury receives pro-rata Cover-Fee settlement for in-flight Cover Calls.
+9. **A Stand's annual Pass volume exceeds $100k** (10M Grain-cents) — the Stand is invited to the Hub API via `MsgEscalateStandToPier`. The Stand accepts the Pier invitation. The Stand→Pier boundary is a soft upgrade, not a ban.
+10. **The Pool dissolves** — the Pool Council (Host + 3 elected + Watcher observer, MAB holders excluded) votes to dissolve. The `PoolDissolutionWaterfall` pays: Cover-Fee contributors first, MAB holders second, Bread holders third (FR-MAB-4 seniority). MAB holders have NO Voice in the dissolution decision (REQ-063).
+
+This happy path is verified by the P6 simtest suite. The simtest is the executable spec.
+
+## UX Acceptance Criteria
+
+(MVP/UX CHECK section 3 of 3 — per run.md MVP/UX CHECK gate)
+
+The v0.7 deliverable MUST meet these explicit criteria (verified in P6 audit):
+
+1. **`go build ./...` + `go test ./...` GREEN** — all packages (v0.1-v0.6 baseline + v0.7 `x/cover` + extensions). No FAIL. The simtest is the executable demonstration.
+2. **`x/cover` module exists with the full Cover surface** — Factory + firewall + floors + gates + tagging (P1) + Charter + governance + staging (P2) + Bill of Rights + Voucher + Pier Index (P5). Layout mirrors `x/hub` (D-039 precedent verified at `x/hub/types/types.go:33-57`).
+3. **Anti-Crowding-Out firewall operational** — `x/cover/firewall/` subpackage rejects any code path routing Cover-Fees outside contributor-pool semantics; `lexicon_meta_cover/` meta-test rejects doc drift. 4 lexicon meta-tests green (x/, docs/, web/, cover/). Defense in depth (D-079).
+4. **11 new locked consts in place + regression tests** — all 11 consts from the v0.7 const firewall additions table, with regression tests asserting their values. No existing locked consts amended.
+5. **MAB coupons NEVER Bread** — `CouponDenomBread` rejected at `ValidateBasic` (FR-MAB-3). The simtest `TestMABIssuance_BreadCoupons_Rejected` passes. MAB issuance ceiling 3× annual surplus enforced at keeper (`TestMABIssuance_AboveCeiling_Rejected` passes).
+6. **Anti-Capture Bill of Rights = 13 rights, non-amendable, non-waivable** — `RightIsWaivable` always returns false; Charter `WaivedRights` field rejected at `ValidateBasic` (REQ-056). `AntiCaptureBillOfRightsCount=13` regression test passes. D-085 (13th right) logged as assumption with `RightNonParticipationNoDenial` candidate if PO did not rule before P5.
+7. **Coverage ≥80%** on `x/cover` + all extensions (`x/bond`, `x/guild`, `x/standing`, `x/stand`).
+8. **G-003 production firewall intact** — `x/cover` references `x/standing`/`x/watcher`/`x/bond`/`x/still` via `expected_keepers.go` shims; no struct imports across `x/<module>/types`. Verified by the lexicon_meta + a G-003 regression test. `x/pact.PactCover` stays as cross-reference (D-084).
+9. **G-006/G-028 go.mod diff EMPTY** — no new Go deps; `x/cover` uses existing cosmos-sdk v0.50.8 + ibc-go v8.2.1. `git diff v0.5.6..v0.6.6 -- go.mod` shows no new require lines.
+10. **Pen-test (self-administered adversarial review via ci-griller)** — the ci-griller red-teams the Anti-Capture Bill + Anti-Crowding-Out firewall + MAB use-of-proceeds lock + secession cooling + Voucher slashing. High/critical findings remediated in P6; P1+ flagged for post-hoc review. Logged as assumption per oy-state §7 remaining-open item 4.
+11. **§7 acceptance criteria met** — ≥1 Cover Pool live (simtest), ≥1 Parent+Chapter secession-eligible (simtest), ≥1 MAB issuance (simtest), Anti-Capture Bill reviewed by bonded Counsel (simtest `MsgCounselReviewBillOfRights` handler), pen-test complete (self-administered), high/critical remediated.

 ## Milestone
-v0.6 — Nomad Web UI (in progress; feature type; tags run on the v0.5.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).

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).

+
+## 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

Three scope-shaping questions were validated interactively with the user before CLARIFY:

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 |

-## IDEATE Traceability (Phase 0 v0.6 — IDEATE stage, autonomy=full)
+## 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).

+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. The 13th is NOT enumerated. Best candidate
+(confidence 0.55): "non-participation MUST NOT deny other mesh products"
+(REQ-085 / FR-NORM-4 norm-chilling defense). Alternatives: "Standing
+portability", "Mesh migration". This is a low-confidence assumption —
+escalated through normal decision flow; NOT auto-decided. The lead-developer
+must surface D-085 to the PO before P5 (Anti-Capture Bill lands in P5). If
+unresolved at full autonomy by P5, log as assumption with the
+NonParticipationNoDenial candidate and proceed.
+
+### Design recommendations (grounded in codebase)
+
+1. **`x/cover` module layout mirrors `x/hub` (D-039 precedent, D-084).**
+   Verified at `x/hub/types/types.go:33-57` + `x/hub/module.go:32-55`. Layout:
+   `x/cover/{module.go, types/{types.go,rights.go,firewall.go,expected_keepers.go,msg_cover.go}, keeper/{keeper.go,msg_server.go,firewall.go,msg_server_simtest_test.go}}`.
+   The `x/pact` `PactCover` enum value (`x/pact/types/types.go:36`) stays as
+   cross-reference; `x/cover` owns the runtime. Confidence 0.90.
+
+2. **Cover-Fee category tagging in `x/cover`, NOT `x/bread` (REQ-050).** No
+   `Grain` struct exists today (`x/bread/types/types.go` has only
+   `BreadScale`/`Params`/`GenesisState`). Adding a tag field to `x/bread`
+   risks the `GrainsPerBread=10000` locked-const firewall. A `CoverFeeTag`
+   struct in `x/cover/types` (`{GrainAmount int64, CategoryTag string,
+   PoolID string}`) is schema-additive and puts the tag where the
+   category-mismatch rejection (FR-COVER-11) lives. Confidence 0.82.
+
+3. **Standing gate via expected-keeper shim (G-003, D-077).** `x/cover`
+   defines a `StandingKeeper` interface
+   (`GetStandingBucket(reachID, category string) (bucket string, score
+   float64, err error)`); the `x/standing` keeper satisfies it structurally.
+   The gate compares the returned bucket string against LOCAL `x/cover`
+   consts `CoverStandingGateTrusted=4.0` / `CoverStandingGatePreferred=4.5`
+   (cross-documented to `x/standing.BucketTrusted`/`BucketPreferred`).
+   Mirrors `x/bond/types/expected_keepers.go:43-49` `StandKeeper` pattern.
+   Confidence 0.88.
+
+4. **MAB as `x/bond` extension (anonymous embed), NOT a new module.**
+   `MAB struct { Bond; CouponKind CouponDenom; AnnualSurplusAtIssuance
+   int64; UseOfProceedsTag string }` in `x/bond/types`. Mirrors GrowthBond
+   at `x/bond/types/types.go:262-265`. `CouponDenom` enum with
+   `CouponDenomBread` rejected at `ValidateBasic` (MissionLockAmendmentRejected
+   pattern at `x/council/types/types.go:242`). 3× ceiling as keeper-level
+   runtime check against current annual surplus. Confidence 0.88.
+
+5. **D-080 tagged streaming + Watcher-witnessed release.** `UseOfProceedsTag`
+   field locked to `"reserve_build_out"` at issuance; keeper enforces
+   proceeds only debit to `CoverPool.ReserveAccount`; misuse → auto-Still
+   (`x/still` exists). `MsgWitnessMABProceedsRelease` requires Watcher quorum
+   (6-of-9, `x/watcher/types/types.go:23`). Confidence 0.84.
+
+6. **Anti-Capture Bill of Rights = 13 RightID consts + 13 Waivable* bool
+   consts (all false) + `RightIsWaivable(id)` always returns false.** Dual
+   firewall: const + `ValidateBasic` gate on Cover-Charter `WaivedRights`
+   field (mirrors `MissionLockAmendable=false` +
+   `MissionLockAmendmentRejected`). In `x/cover/types/rights.go` (NOT a
+   separate `x/cover/rights` package — D-079 specifies separate
+   `x/cover/firewall` package for enforcement, but rights *declaration* is a
+   type/const surface). Confidence 0.90.
+
+7. **Anti-Crowding-Out firewall (D-079) = `x/cover/firewall` subpackage
+   (runtime `CheckCoverFeeRouting`) + `lexicon_meta_cover` meta-test
+   (test-time doc-drift rejection).** Defense in depth. The firewall is the
+   enforcement mechanism for the `RightNoTaxOnPersonalStash` right (the
+   right is policy; the firewall is implementation). Confidence 0.82.
+
+8. **Guild extension: `ParentGuildID string` + `IsChapter bool` +
+   `SecessionTermsHash []byte` + `GoodStandingLiens []Lien`.** No `GuildKind`
+   enum (schema-additive without a new locked-const count).
+   `SecessionTerms` struct hash-pinned at creation (immutable).
+   `Lien.SecuredAtFounding=true` liens NOT freely increasable. Cooling consts
+   `CoolingSecessionCoverActiveDays=21` / `CoolingSecessionNonCoverDays=14`
+   in `x/guild/types` (protocol minimum; Chapter MAY specify longer, NOT
+   shorter). Confidence 0.85.
+
+9. **Shadow vouch 50% weight (REQ-060) = new const
+   `ShadowVouchWeightMultiplier=0.5` + new `IsShadow bool` field on `Vouch`
+   + post-multiplier branch in `GetVoucherWeight`.** The const makes the 0.5×
+   mission-locked (REQ-060 locked) and regression-testable. A hardcoded 0.5
+   in a branch is invisible to the locked-const firewall. Confidence 0.85.
+
+10. **Cover Claims Voucher (REQ-055) = `CoverClaimsVoucher` struct in
+    `x/cover/types` (NOT `x/standing`).** Bond =
+    `CoverClaimsVoucherBondMultipleAvgCall=10` × Pool avg Call size. Slash
+    via existing `x/standing.Slash` with new
+    `SlashReasonFraudulentCoverCall` const (cross-Pool via Standing bucket
+    drop). No self-adjudication: `MsgFileCoverCall` handler rejects if
+    `voucherReachID == claimantReachID` (FR-CPCV-2). Confidence 0.82.
+
+### Persona assessment
+
+Active for v0.7: backend-engineer (all phases — the bulk), lead-developer
+(all phases — coordination + D-085 escalation + pen-test assumption),
+security-engineer (all phases — highest security density since v0.5),
+cosmos-engineer (all phases — advisory; x/cover follows x/hub pattern).
+
+Deactivated: frontend-engineer (zero UI), docs-writer (no docs-content),
+mesh-engineer (no bearer work), data-engineer (no genesis-schema work).
+ci-security-auditor: off until P6 (final review/audit/ship).
+
+Full PERSONAS.md written to `.ciagent/oy/PERSONAS.md`.
+
+### Pitfalls (avoid)
+
+- Do NOT centralize Cover risk at the Root-Pool (historic AOUW collapse
+  reproduced; Anti-Crowding-Out firewall is the defense).
+- Do NOT enforce uniform SoB content (historic centralization; FR-CHTR-5).
+- Do NOT add `CategoryTag` to `x/bread/types.Grain` (risks GrainsPerBread
+  locked-const firewall; use CoverFeeTag in x/cover).
+- Do NOT import `x/standing/types` structs in `x/cover` (G-003; use
+  expected-keeper shim).
+- Do NOT retire `x/pact.PactCover` enum value (stays as cross-reference).
+- Do NOT make 1.5× floor a Params field (locked const; only 2.5× ceiling is
+  governance-tunable within bounds).
+- Do NOT allow `CouponDenomBread` MAB (rejected at ValidateBasic).
+- Do NOT give MAB holders Voice (REQ-063 locked; claimants, not Masons).
+- Do NOT add a `GuildKind` enum (bool IsChapter + ParentGuildID string is
+  schema-additive without a new locked-const count).
+- Do NOT make cooling periods reducible (REQ-064 locked; secured at founding).
+- Do NOT implement Shadow vouch 50% without a const (locked-const firewall
+  invisibility).
+- Do NOT put `CoverClaimsVoucher` in `x/standing` (role is Cover-specific).
+- Do NOT auto-decide the 13th right (D-085 escalation; confidence 0.55).

+# 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-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).

+> `oy-spec`; it prevents re-proposing shipped or explicitly-deferred REQs.

+- Skeleton-first until mainnet gate (D-020 pattern)
+- Zero Go deps except GRILL-approved runtime exceptions
+- Coverage >=80% on shipped packages
+- Multi-project mode active; project slug = `oy`

+## 8. Open questions for the ciagent
+<!-- TODO: bulleted; the ciagent logs assumptions if unanswered at autonomy=full -->
+
+## 9. Changelog
+<!-- Every spec revision MUST be a `docs(spec):` commit (see commit convention
+     block below). One row per revision. -->
+| Spec-v | Date | Commit (docs(spec):) | What changed | REQs affected |
+|--------|------|----------------------|--------------|---------------|
+| 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 firewall is an ALLOW-LIST of permitted routing destinations (D-088(2)
+// — the concrete simtest-enforceable shape). The RouteCoverFee handler
+// passes the destination holder string to CheckCoverFeeRouting; the
+// firewall checks the destination is non-empty AND not a known bad

+// string "root-pool-operating-expenses" (the Anti-Crowding-Out case) and
+// accepts any other non-empty string. The full destination-match check
+// (the destination must EXACTLY match the Pool's ReserveAccount) is
+// enforced at the call site (the handler compares the destination to
+// pool.ReserveAccount BEFORE calling the firewall; the firewall is the

+// x/cover depends on (G-003 firewall — ibc-go expected-keepers convention).

+// The cover runtime (REQ-046, REQ-047, REQ-049, REQ-050) depends on FOUR
+// cross-module keepers:
+//
+//  1. x/standing (StandingKeeper) — the LaunchCoverPool handler asserts the
+//     host's Standing per category meets the locked gate (D-077: Travel
+//     requires >= Trusted; HealthMCS requires >= Preferred; IncomePause
+//     uses the Trusted gate). The handler queries GetStandingBucket for the
+//     bucket string + score and compares against the CoverStandingGateTrusted
+//     / CoverStandingGatePreferred consts. This is the v0.7 P1 cover-launch
+//     edge: the Cover module references a holder's Standing by reach-id +
+//     category (G-003 — no struct import of x/standing/types).
+//
+//  2. x/watcher (WatcherKeeper) — the LaunchCoverPool handler emits a
+//     Watcher attestation over the launch payload (REQ-046). The attestation
+//     is the Watcher's signed observation that the pool was launched per
+//     the validated terms. P1 stubs the attestation in simtest; the live
+//     x/watcher pipeline lands in P3.
+//
+//  3. x/bond (BondKeeper) — the FileCoverCall handler (P4) consults the
+//     Mutual Aid Bond (MAB) posted by the adjudicating Voucher. P1 DEFINES
+//     the interface but does NOT use it (the MAB misuse auto-Still + the
+//     Voucher adjudication land in P4). The interface is here so the P1
+//     wiring is stable.
+//
+//  4. x/still (StillKeeper) — the RouteCoverFee handler invokes
+//     Still(poolID, "below reserve floor") on the below-floor auto-pause
+//     (D-089(1)) and the P4 MAB-misuse auto-Still. P1 satisfies this by a
+//     simtest-local stub (x/still/keeper is empty; NOT a real keeper). A
+//     nil StillKeeper skips the auto-Still (simtest wiring — documented).
+//
+// All four dependencies are expressed as INTERFACES defined HERE (in
+// x/cover/types), NOT as struct imports of any x/<module>/types. The
+// concrete keepers (or simtest stubs) satisfy these interfaces structurally

+// The guild runtime (REQ-051, REQ-053, REQ-057, REQ-058) depends on TWO
+// cross-module keepers:
+//
+//  1. x/stand (StandKeeper) — the OneTapExitStand handler asserts the named
+//     Stand is a Household (REQ-057) before dissolving it; the
+//     DelegateConfederationVoice handler asserts the named Stand is a
+//     Confederation (REQ-058) before recording the delegation. The handler
+//     queries GetStand for the Stand type (an opaque string — "Household" or
+//     "Confederation") and compares. This is the v0.7 P3 household-edge: the
+//     Guild module references a Stand by ID-string (G-003 — no struct import
+//     of x/stand/types).
+//
+//  2. x/stash (StashKeeper) — the OneTapExitStand handler returns the
+//     dissolved Household Stand's assets to the Holder's Stash (REQ-057).
+//     The handler calls ReturnAssetsToHolder; the simtest stub records the
+//     call for assertion (no actual asset transfer in simtest).
+//
+// Both dependencies are expressed as INTERFACES defined HERE (in
+// x/guild/types), NOT as struct imports of any x/<module>/types. The
+// concrete keepers (or simtest stubs) satisfy these interfaces structurally
+// (the P3 simtest wires stubs per G-003 test exemption); the handler depends
+// on the interface, preserving G-003's intent (no cross-module struct
+// coupling, no import cycles).
+//
+// Lexicon note (REQ-012): "Guild", "Chapter", "Stand", "Household",
+// "Confederation", "Stash", "Holder", "Reach", "Voice" are all lexicon-clean.
+// The project-wide 10 banned terms NEVER appear (enforced by lexicon_meta +

+// type name (cross-doc to x/stand.StandType — "Household", "Confederation",
+// etc.); the handler compares the string.
+//
+// No struct import of x/stand/types — the interface is the by-ID-string
