 # P3 Ship Verification — v0.2 Phase 3 (Councils + Forex)
 **Branch**: `oy/phase/03-councils-forex`
 **Phase**: P3 — Councils + Forex (REQ-011, Forex v1)
 **Tag target**: `v0.1.3` (orchestrator ships; executor does NOT merge/tag/push)
 **Date**: 2026-08-17
 ## Summary
 Phase 3 ships two new Mesh modules — `x/council` (3-Council enum
 Mesh/Guild/Stand with Mission Lock as a `const bool` + Voice/SignalKind/
 TallyResult types mirroring `x/gov`) and `x/forex` (Forex Engine v1 stub:
 ForexPair with lexicon-clean "Bread/Asset" labels + RateOracle interface +
 StubOracle + 4-OracleKind enum) — both referencing x/stand and x/guild
 by-ID-string (G-003). All six P3 tasks executed atomically with per-task
 commits. Build green, tests green, coverage ≥80% on both new packages,
 lexicon firewall green (forex is the highest lexicon-risk module per
 RESEARCH §1.10 — verified clean), Mission Lock invariant green.
 ## Must-Haves (from PLANS.md P3 Must-Haves)
 | Must-Have | Status | Evidence |
 |---|---|---|
 | `x/council`, `x/forex` each have `types/types.go` + `types/types_test.go` | ✅ | 6 files created (council: types.go+types_test.go+genesis.go; forex: types.go+types_test.go+genesis.go) |
 | `go build ./...` and `go test ./...` green | ✅ | `go build ./...` → BUILD OK; `go test ./... -count=1` → all 22 packages ok (0 FAIL) |
 | ≥80% coverage on `x/council/types`, `x/forex/types` | ✅ | council 96.4%, forex 100.0% |
 | Council locked-const: exactly 3 types (Mesh, Guild, Stand) | ✅ | `CouncilKindCount == 3`, `AllCouncilKinds()` returns MeshCouncil/GuildCouncil/StandCouncil; `TestCouncilKindCountLockedConst` + `TestAllCouncilKindsNames` |
 | **Mission Lock invariant**: `MissionLockAmendable == false`, test asserts non-amendable (highest-severity) | ✅ | `MissionLockAmendable` const bool false; `TestMissionLockAmendableConstFalse` + `TestMissionLockAmendableCannotBeSetTrue` (const is the firewall — cannot be reassigned) |
 | `TallyResult` shape mirrors `x/gov` (A-204) for future wiring | ✅ | Fields yes/no/abstain/nowithveto/total/quorum_met; JSON tags verified in `TestTallyResultStructShape`; NoWithVeto always 0 (anti-greed, no veto option) |
 | `VoteOption` has no "no-with-veto" (anti-greed) | ✅ | N/A — council uses `TallyResult` with NoWithVeto locked to 0 (no separate VoteOption enum; the TallyResult field is the parity-with-x-gov shape with the anti-greed invariant); `TestTallyResultNoWithVetoAlwaysZero` |
 | Forex pair labels lexicon-clean (no banned tradable-unit terms); `RateOracle` interface compiles | ✅ | ForexPair uses `base_asset`/`quote_asset` JSON tags (A-208 "Bread/Asset"); `TestForexPairStructFields` + `TestForexPairLabelsLexiconClean`; `RateOracle` interface compiles (`TestRateOracleInterfaceCompiles` + `TestStubOracleSatisfiesInterface`) |
 | Lexicon assertion in both new test files | ✅ | `TestLexiconNoBannedTermsInCouncilPackage` + `TestLexiconNoBannedTermsInCouncilTestFile`; `TestLexiconNoBannedTermsInForexPackage` + `TestLexiconNoBannedTermsInForexTestFile` |
 | `ValidateGenesis` ID-uniqueness + referential integrity (Council) | ✅ | council rejects dup/empty council-ids + dup/empty voice-ids + unknown kinds/signals + Stand Council without stand-id-ref + Guild Council without guild-id-ref + Voice with unknown council-id (referential integrity P3-01-03); forex rejects dup/empty pair-ids + dup/empty provider-ids + empty base/quote-asset + unknown oracle-kind (A-212) |
 | Git tag `v0.1.3` | ⏸ DEFERRED | Orchestrator ships (executor does NOT tag/merge/push per instructions) |
 ## Tasks Committed (6)
 | Task | Commit | Description |
 |---|---|---|
 | P3-01-01 | `81708bd` | council types — 3 CouncilKind enum, Mission Lock const, Voice/SignalKind/TallyResult |
 | P3-02-01 | `73aa90f` | forex types — ForexPair (Bread/Asset labels), RateOracle iface, 4 OracleKind enum, StubOracle |
 | P3-01-02 | `02d02c8` | council types tests — locked-const, Mission Lock invariant, SignalKind, TallyResult, lexicon |
 | P3-01-03 | `7804fdb` | council genesis schema — Voice tally referential integrity, Mission Lock check |
 | P3-02-02 | `94eeca6` | forex types tests — OracleKind enum, RateOracle iface, StubOracle sentinel, lexicon (highest risk) |
 | P3-02-03 | `a7567e2` | forex genesis schema — ValidatePairs/ValidateProviders, dup-id rejection |
 ## Build / Test / Coverage Results
 ### `go build ./...`
 ```
 BUILD OK
 ```
 ### `go test ./... -count=1`
 - 22 packages with tests, all `ok` (0 FAILs)
 - Total test count: **264** (up from 207 baseline → +57 new tests across council + forex)
 - Packages with no test files: lexicon, x/identity/types, x/processing/types, x/rootpool/types, x/vault/types (unchanged from baseline)
 ### `go test -cover ./x/council/types/... ./x/forex/types/...`
 | Package | Coverage | Target | Pass |
 |---|---|---|---|
 | `x/council/types` | **96.4%** | ≥80% | ✅ |
 | `x/forex/types` | **100.0%** | ≥80% | ✅ |
 ### Lexicon meta-test (`go test -run TestLexiconMeta .`)
 - `TestLexiconMetaNoBannedTermsInX` — PASS (scans all `x/**/*.go` production + test for 10 banned terms; council + forex files clean)
 - `TestLexiconMetaSelfTestTable` — PASS (G-009 self-test table for all 10 banned terms)
 - `TestLexiconMetaBannedTermsCount` — PASS
 - `TestLexiconMetaNoFalsePositiveOnOpenYield` — PASS (word-boundary matcher, "openyield" not flagged)
 ### G-003 by-ID-string invariant (`go test -run TestG003 ./x/window/...`)
 - `TestG003NoCrossModuleStructImportsInProduction` — PASS (no production `.go` file under `x/` imports a foreign `x/<module>/types` package; council references x/stand + x/guild by-ID-string; forex has no cross-module refs)
 ## Module Details
 ### x/council (REQ-011, D-022)
 - **CouncilKind enum**: MeshCouncil, GuildCouncil, StandCouncil — exactly 3 (REQ-011)
 - **Council struct**: id, kind, stand-id-ref (optional, by-ID-string to x/stand — P1-02-01), guild-id-ref (optional, by-ID-string to x/guild — P1-03-01), members ([]CouncilMember), voice-threshold
 - **CouncilMember struct**: reach-id (lexicon-clean holder identifier — NOT the banned financial holder term), voice-weight, joined-at
 - **Voice struct**: id, council-id, proposer-reach, signal-kind, target-ref, tally, timestamp
 - **SignalKind enum**: Stash, Standing, Vouch, Capital — exactly 4 (the four Freeholder signals, cross-ref v0.1 REQ-005 / vision §9.1 x/standing FreeholderSignals)
 - **TallyResult struct**: yes, no, abstain, nowithveto (always 0 — anti-greed), total, quorum-met — mirrors x/gov shape (A-204)
 - **Mission Lock invariant**: `MissionLockAmendable` const bool false — the highest-severity regression firewall; the const can NEVER be set true (compile-time const)
 - **Genesis**: `GenesisState{Councils, Voices, Params}`, `DefaultGenesisState()`, `ValidateGenesis` (rejects dup/empty council-ids, dup/empty voice-ids, unknown kinds/signals, Stand Council without stand-id-ref, Guild Council without guild-id-ref, Voice with unknown council-id [referential integrity]); data-engineer's `ValidateCouncils` + `ValidateVoices` + `MissionLockCheck` wired into the genesis load path (G-008)
 ### x/forex (Forex v1, D-030)
 - **ForexPair struct**: id, base-asset, quote-asset, decimals — uses "Bread/Asset" style labels (A-208), NOT the banned financial tradable-unit terms (lexicon-hostile per RESEARCH §1.10)
 - **RateOracle Go interface**: `GetRate(pairID) (rate uint64, timestamp int64, err error)` — no impl in v0.2 (Phase 3 wires Piers)
 - **OracleProvider struct**: id, name, kind
 - **OracleKind enum**: Chainlink, Pyth, UMA, Internal — exactly 4 (Forex v1)
 - **SpotRate struct**: pair-id, rate, timestamp, provider-id (by-ID-string refs per G-003)
 - **StubOracle**: stub keeper; `GetRate` returns sentinel `ErrOracleNotIntegrated` ("forex oracle not integrated (Phase 3 wires Piers)")
 - **SpreadCapBps**: const 0 (A-214 documented placeholder; test asserts ≥0; v0.3 may set a positive cap)
 - **Genesis**: `GenesisState{Pairs, Providers, Params}`, `DefaultGenesisState()`, `ValidateGenesis` (rejects dup/empty pair-ids, dup/empty provider-ids, empty base/quote-asset, unknown oracle-kind); data-engineer's `ValidatePairs` + `ValidateProviders` (G-008)
 ## Deviation: genesis.go created in Wave 1 alongside types.go (P3-01-01 / P3-02-01)
 The plan ordered genesis.go as tasks P3-01-03 and P3-02-03 (after the test
 tasks P3-01-02 and P3-02-02), but `types.go` references `ValidateCouncils`/
 `ValidateVoices` (council) and `ValidatePairs`/`ValidateProviders` (forex)
 — the genesis helpers — and the build must be green after each per-task
 commit. I therefore created `genesis.go` with the Validate* helpers in the
 Wave 1 types tasks (P3-01-01 and P3-02-01), and the Wave 2 genesis tasks
 (P3-01-03 and P3-02-03) then refined the doc/comments to make the
 deliverable explicit and committed the refinement. This matches the P2
 deviation pattern (documented in P2_SHIP_VERIFICATION.md). All four tasks
 are individually committed; the deviation is structural only (genesis
 helper landed in the types task to keep the build green, then was refined
 in the genesis task). No semantic change to the plan's deliverables.
 ## Lexicon Compliance Notes (Forex is highest risk per RESEARCH §1.10)
 - **No banned literals** in any new `x/council/**/*.go` or `x/forex/**/*.go`
  file (production or test). The 10 banned terms (bank, deposit, interest,
  yield, currency, dollar, euro, account, savings, depositor) are
  referenced only via the `lexicon` package helpers
  (`lexicon.FindBannedTerm`, `lexicon.BannedTerms`) in test files.
 - **Council module** uses "reach-id"/"voice-holder"/"proposer-reach"
  (NOT the banned financial holder term — the lexicon-clean holder
  identifier per RESEARCH §2). Comments deliberately avoid the banned term
  even in "NOT <banned-term>" form (the word-boundary matcher would flag it).
 - **Forex module** uses "Forex" (allowed — vision §13 names it; NOT in the
  banned list), "base-asset"/"quote-asset" (A-208 — NOT the banned
  tradable-unit terms), "Bread"/"Asset" sample labels (A-208). The banned
  financial terms for tradable units (the three lexicon-hostile terms
  per RESEARCH §1.10) NEVER appear in source. "fx" is borderline but
  avoided (the module name is "forex" not "fx").
 - **Self-bootstrapping**: each test file has a
  `TestLexiconNoBannedTermsIn*TestFile` self-check that asserts the test
  file itself contains no banned literals (the lexicon helpers must be
  used, not inline strings).
 - **Project-wide meta-test** (`lexicon_meta_test.go`) scans ALL
  `x/**/*.go` including the new council + forex files — PASS.
 ## Pre-existing LSP noise (not P3 scope)
 The LSP reports errors in `x/watcher/` files (cosmos-sdk/codec imports) and
 `go.mod` (version "v2.0.1" invalid). These are **pre-existing** and **not
 in P3 scope** — `x/watcher` is a v0.1 module with stale cosmos-sdk
 references that are not part of the v0.2 skeleton (the v0.2 skeleton is
 zero-deps; `go build ./...` succeeds because the watcher files are
 excluded from the build path or compile cleanly via `go build`).
 `go build ./...` and `go test ./...` both PASS, confirming the LSP noise
 does not affect the build. (Same note as P1/P2 ship verification.)
 ## Orchestrator Handoff
 - **Do NOT merge/tag/push** — executor leaves the branch
  `oy/phase/03-councils-forex` with 6 commits for the orchestrator to ship
  as tag `v0.1.3`.
 - All P3 must-haves pass except the git tag (deferred to orchestrator per
  instructions).
 - No regressions: all v0.1 baseline tests + all v0.2-P1 tests + all v0.2-P2
  tests + 57 new P3 tests = 264 total, all green.

 - [x] Lexicon assertion in all 3 test files (bond, bearers-ext, satellite).
 - [x] `ValidateGenesis` ID-uniqueness (all 3) + genesis clamp (Bond).
 - [ ] Git tag `v0.1.4` — ⛔ NOT created (executor instructed NOT to merge/tag/push).
 ## Deliverable Detail
 ### P4-01-01 — Bond types (backend-engineer, REQ-021, D-028)
 - `CouponCapBps = 800` (8%), `CouponFloorBps = 0` (0%) — LOCKED `const`.
 - `Bond` struct: id, issuer-stand-id (by-ID-string ref to x/stand per G-003), principal-grain, coupon-bps, term-days, issued-at, maturity, status.
 - `BondStatus` enum (5): Issued, Active, Matured, Defaulted, Repaid.
 - `Issue(...)` stub: constructs Bond with coupon clamped, status BondIssued.
 - `Clamp(couponBps)` mirrors `x/feecovenant` Clamp shape: `min(cap, max(floor, coupon))`.
 - `AllBondStatuses()` returns 5.
 - `DefaultParams`, `GenesisState` (bonds), `DefaultGenesisState`, `ValidateGenesis` (rejects dup bond-ids).
 ### P4-02-01 — Bearers extension (cosmos-engineer, D-029, A-209)
 - EXTENDED existing `x/bearers/types/types.go` (NOT a new module).
 - `BearerTransport` Go interface: `Send`, `Receive`, `Status` — no impl.
 - `OYLRLink` struct: gateway-id, range-meters, frequency-mhz, surveillance-resistant=true.
 - `BeaconFrame` struct: beacon-id, ephemeral-id, payload-bytes, ttl.
 - PRESERVED existing `BearerType` enum + `AllBearers()` (OY-LR still in the 6).
 - `DefaultParams`/`GenesisState` unchanged (no break).
 ### P4-03-01 — Satellite types (cosmos-engineer, REQ-009, D-021, A-215)
 - `L2Chain` enum (5): Polygon active; Base, Arbitrum, Optimism, Solana StatusPending (D-021).
 - `TransferChannel` struct: port-id, channel-id, counterparty, status.
 - `ChannelStatus` enum (4): Init, TryOpen, Open, Closed (ICS-20 handshake).
 - `WrappedBreadDenom` struct: denom, trace-path (IBC trace encoding).
 - `Packet` stub struct: sequence, source-port, source-channel, dest-port, dest-channel, data, timeout-height, timeout-timestamp (ICS-20 v1 shape).
 - NO ibc-go import (zero external deps — A-201).
 - `AllL2Chains()` returns 5; `AllChannelStatuses()` returns 4.
 - `DefaultParams`, `GenesisState` (channels + denoms), `DefaultGenesisState`, `ValidateGenesis` (rejects dup channel-ids + dup denoms).
 ### P4-01-02 — Bond tests (security-engineer, REQ-021)
 - Clamp invariant tests: below floor → floor, above cap → cap, in range → unchanged.
 - `CouponCapBps == 800` locked-const; `CouponFloorBps == 0` locked-const.
 - `BondStatus` enum coverage (5); `Issue` stub callable + clamps above cap.
 - `ValidateGenesis` rejects dup bond-id, unknown status, coupon above cap.
 - Lexicon assertion (lexicon helpers, no banned literals — A-210 coupon-only).
 ### P4-01-03 — Bond genesis (data-engineer, REQ-021)
 - `ValidateBonds` enforces coupon-bps within [floor, cap] at genesis load (D-028 clamp).
 - `genesis_test.go`: boundary tests (at floor, at cap, just above cap, just below cap).
 ### P4-02-02 — Bearers tests extension (security-engineer, D-029)
 - `BearerTransport` interface signature test (stub impl satisfies it).
 - `OYLRLink` non-empty + surveillance-resistant == true; `BeaconFrame` non-empty + ttl > 0.
 - OY-LR still in AllBearers() (REGRESSION: existing v0.1 tests pass).
 - Lexicon assertion (extends existing test file).
 ### P4-03-02 — Satellite tests (security-engineer, REQ-009)
 - `L2Chain` exactly 5 (Polygon + 4 stubs); Polygon only active (D-021).
 - `ChannelStatus` coverage (4); `Packet` fields match ICS-20 v1 (JSON tags).
 - `WrappedBreadDenom` trace-path encoding; `ValidateGenesis` rejects dup channel-id + dup denom.
 - Lexicon assertion (no banned terms — use Holder/Reach).
 ### P4-04-01 — Phase ship verification (lead-developer)
 - This document. Full build/test/coverage verification.
 ## Test Counts
 - **Total `--- PASS`: 303** (leaf tests; some names repeat across packages).
 - **Total `--- FAIL`: 0**.
 - **Packages with tests: 21** (4 packages have no test files: identity, processing, rootpool, vault — same as v0.1 baseline).
 ## Notes
 - The bond `genesis.go` was created in P4-01-01's commit (needed for `go build` — `ValidateBonds` is referenced by `ValidateGenesis` in types.go). P4-01-03 adds the dedicated `genesis_test.go` clamp assertions and owns the data-engineer's genesis-schema deliverable.
 - Pre-existing LSP errors in `x/watcher/` (cosmos-sdk imports not vendored) are unchanged and do not affect `go build ./...` or `go test ./...` (the watcher module builds under the v0.1 baseline; these are stale LSP diagnostics, not build errors).
 - No merge, no tag, no push performed (per executor instructions).
