+# P2 Ship Verification — v0.2 Phase 2 (Pacts + Partners)
+
+**Branch**: `oy/phase/02-pacts-partners`
+**Phase**: P2 — Pacts + Partners (REQ-020, REQ-018)
+**Tag target**: `v0.1.2` (orchestrator ships; executor does NOT merge/tag/push)
+**Date**: 2026-08-17
+
+## Summary
+
+Phase 2 ships two new Mesh modules — `x/pact` (6-Pact enum with Mission-Lock
+invariant) and `x/partner` (4-tier Partner Spectrum with registry keeper stub)
+— both consuming Window + Stand refs from P1 by-ID-string (G-003). All five
+P2 tasks executed atomically with per-task commits. Build green, tests green,
+coverage ≥80% on both new packages, lexicon firewall green.
+
+## Must-Haves (from PLANS.md P2 Must-Haves)
+
+| Must-Have | Status | Evidence |
+|---|---|---|
+| `x/pact`, `x/partner` each have `types/types.go` + `types/types_test.go` | ✅ | 4 files created (pact: types.go+types_test.go+genesis.go; partner: types.go+types_test.go) |
+| `go build ./...` and `go test ./...` green | ✅ | `go build ./...` → build OK; `go test ./...` → all ok (20 packages with tests) |
+| ≥80% coverage on `x/pact/types`, `x/partner/types` | ✅ | pact 95.9%, partner 100.0% |
+| Pact locked-const: exactly 6 types (vision §16 names) | ✅ | `PactTypeCount == 6`, `AllPactTypes()` returns Pause/Ground/Stance/Cover/StandRegistry/HubAPI; `TestPactTypeCountLockedConst` + `TestAllPactTypesNames` |
+| Partner locked-const: exactly 4 tiers (Op, MasterOp, Pier, Anchor) | ✅ | `PartnerTierCount == 4`, `AllPartnerTiers()`; `TestPartnerTierCountLockedConst` + `TestAllPartnerTiersNames` |
+| Mission-Lock invariant: Pause/Ground/Stance core terms non-amendable | ✅ | `MissionLockAmendable == false` const + per-type `AmendableCoreTermsPause/Ground/Stance == false` consts; `TestMissionLockAmendableConstFalse` + `TestMissionLockCoreTermsNonAmendable` (highest-severity regression firewall) |
+| Lexicon assertion in both new test files | ✅ | `TestLexiconNoBannedTermsInPactPackage` + `TestLexiconNoBannedTermsInPactTestFile`; `TestLexiconNoBannedTermsInPartnerPackage` + `TestLexiconNoBannedTermsInPartnerTestFile` |
+| `ValidateGenesis` ID-uniqueness checks | ✅ | pact rejects dup/empty pact-ids + unknown types; partner rejects dup/empty partner-ids (A-212 upgrade) |
+| Git tag `v0.1.2` | ⏸ DEFERRED | Orchestrator ships (executor does NOT tag/merge/push per instructions) |
+
+## Tasks Committed (5)
+
+| Task | Commit | Description |
+|---|---|---|
+| P2-01-01 | `d00d51d` | pact types — 6 PactType enum, Mission-Lock invariant, execute stubs |
+| P2-02-01 | `f74e4ae` | partner types — 4-tier Partner Spectrum, registry keeper stub |
+| P2-01-02 | `c050e52` | pact types tests — locked-const, Mission-Lock, execute stubs, lexicon |
+| P2-01-03 | `76d5f5d` | pact genesis schema — ValidatePacts rejects dup ids, Mission-Lock check |
+| P2-02-02 | `363b367` | partner types tests — locked-const, registry, ListByTier, lexicon |
+
+## Build / Test / Coverage Results
+
+### `go build ./...`
+```
+build OK
+```
+
+### `go test ./... -count=1`
+- 20 packages with tests, all `ok` (no FAILs)
+- Total test count: **207** (up from 143 baseline → +64 new tests across pact + partner)
+- 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/pact/types/... ./x/partner/types/...`
+| Package | Coverage | Target | Pass |
+|---|---|---|---|
+| `x/pact/types` | **95.9%** | ≥80% | ✅ |
+| `x/partner/types` | **100.0%** | ≥80% | ✅ |
+
+### Lexicon meta-test (`go test -run TestLexiconMeta .`)
+- `TestLexiconMetaNoBannedTermsInX` — PASS (scans all `x/**/*.go` production + test for 10 banned terms)
+- `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; pact + partner conform — refs are by-ID-string)
+
+## Module Details
+
+### x/pact (REQ-020, A-207: ONE module with enum)
+- **PactType enum**: Pause, Ground, Stance, Cover, StandRegistry, HubAPI — exactly 6 (vision §16)
+- **PactStatus enum**: Proposed, Active, Fulfilled, Voided
+- **Pact struct**: id, type, parties ([]string Reach IDs), terms ([]byte), status, execute-msg-ref, window-id-ref (string, G-003), stand-id-ref (string, G-003)
+- **Per-type Execute* stubs**: ExecutePause/Ground/Stance/Cover/StandRegistry/HubAPI — each transitions Proposed→Active, guards on type + status; ExecuteStandRegistry requires non-empty stand-id-ref
+- **Mission-Lock invariant**: `MissionLockAmendable` const bool false + per-type `AmendableCoreTermsPause/Ground/Stance` const flags false; Cover/StandRegistry/HubAPI amendable. `MissionLockAmendableCoreTerms(type)` helper
+- **AllPactTypes()** returns exactly 6 in vision §16 order
+- **Genesis**: `GenesisState{Pacts []Pact}`, `DefaultGenesisState()`, `ValidateGenesis` (rejects dup/empty pact-ids, unknown types, bad JSON); data-engineer's `ValidatePacts` + `MissionLockCheck` wired into the genesis load path (G-008)
+
+### x/partner (REQ-018, D-026)
+- **PartnerTier enum**: Op, MasterOp, Pier, Anchor — exactly 4 (vision §13). "Op" not "operator" — lexicon-clean per RESEARCH §1.6
+- **PartnerStatus enum**: Pending, Active, Suspended, Revoked
+- **CredentialType enum**: Eresidency, Biometric, Vouch, Custom
+- **CredentialRef struct**: provider-id, credential-type, ref-uri (opaque URI; Pier credential routing deferred per Q5)
+- **Partner struct**: id, tier, name, reach-id (string, G-003), region, credential-ref, status
+- **Registry keeper stub**: `Keeper` with `NewKeeper`, `AddPartner`, `GetPartner`, `ListPartners`, `ListByTier` (in-memory, mutex-safe)
+- **AllPartnerTiers()** returns exactly 4 in vision §13 order
+- **Genesis**: `GenesisState{Partners []Partner}`, `DefaultGenesisState()`, `ValidateGenesis` (rejects dup/empty partner-ids, bad JSON)
+
+## Deviation: genesis.go created in P2-01-01 alongside types.go
+
+The plan ordered genesis.go as task P2-01-03 (after the test task P2-01-02),
+but `types.go` references `ValidatePacts` (the genesis helper) and the build
+must be green after each per-task commit. I therefore created `genesis.go`
+with `ValidatePacts` + `MissionLockCheck` in P2-01-01, and P2-01-03 then
+extended it (wiring `MissionLockCheck` INTO `ValidatePacts` so the genesis
+load path enforces the Mission-Lock check alongside id-uniqueness) and
+committed the extension as the P2-01-03 deliverable. Both 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
+
+- **No banned literals** in any new `x/**/*.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.
+- **Partner module** uses "Op"/"MasterOp"/"Pier"/"Anchor" (not "operator", which implies a banned financial term per RESEARCH §1.6). Verified lexicon-clean.
+- **Pact module** avoids "account" — uses "Holder"/"Reach" conventions. The term "parties" ([]string of Reach IDs) is used for the Pact's participating Reach IDs.
+- **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 pact + partner files — PASS.
+
+## Pre-existing LSP noise (not P2 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
+P2 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.
+
+## Orchestrator Handoff
+
+- **Do NOT merge/tag/push** — executor leaves the branch `oy/phase/02-pacts-partners` with 5 commits for the orchestrator to ship as tag `v0.1.2`.
+- All P2 must-haves pass except the git tag (deferred to orchestrator per instructions).
+- No regressions: all v0.1 baseline tests (143) + all v0.2-P1 tests + 64 new P2 tests = 207 total, all green.
