+# Component 1: OY Chain & Mirror — Phase 1 Skeleton
+
+## Status
+v0.0.1 — skeleton with type definitions and locked-constant tests
+
+## Vision References
+- §7: Architecture — Three Layers and the Mirror
+- §3: Still/Stir (pause/resume)
+
+## Modules
+
+### x/watcher — Watcher Bond & Attestation Quorum
+- `types.Watcher` — bonded Watcher (§7: 100,000 Bread minimum bond)
+- `types.Attestation` — daily reserve snapshot signed by a Watcher
+- `types.ReserveSnapshot` — off-chain reserve state (off-chain total, on-chain Bread, basket breakdown)
+- `types.QuorumStatus` — QuorumMet / QuorumLost / StaleEpoch
+- `types.SlashReason` — InsufficientBond / StaleAttestation / GeographicCollusion / Forgery
+
+**Locked constants (§7):**
+- `MinBond = 100000` (100,000 Bread)
+- `Quorum = 6` (6-of-9)
+- `MaxWatchers = 9`
+- `AttestationEpochHours = 24` (daily)
+
+### x/mirror — Reserve Ratio Publication
+- `types.NavPerBread` — Net Asset Value per Bread (§4.2)
+- `types.ReserveRatio` — real-time published ratio with quorum flag
+
+### x/still — Pause/Resume (Still/Stir)
+- `types.StillState` — StirActive / StillPaused (§3)
+- `types.StillReason` — CouncilVote / QuorumLost / SecurityAlert
+- `types.StillRecord` — tracks pause events
+- Auto-still on quorum lost (§4.2: Forge/Fold blocked until quorum restored)
+
+## Tests
+12 tests, all passing:
+- Watcher: MinBond, Quorum, MaxWatchers, AttestationEpoch, DefaultParams (5)
+- Still: DefaultStillState, AutoStillOnQuorumLost, StillStates (3)
+- Mirror: DefaultPublishInterval, ModuleName, NavPerBreadStruct, ReserveRatioQuorum (4)
+
+## What's NOT in this skeleton (deferred to P1 completion)
+- Cosmos SDK app.go full integration (requires SDK v0.50+ dependency resolution)
+- Keeper implementations (BondWatcher, SubmitAttestation, VerifyQuorum, SlashWatcher)
+- CLI commands (oyd tx watcher bond, oyd query watcher quorum)
+- Proto definitions (Buf-generated types)
+- CometBFT consensus setup
+- Genesis import/export
+
+## Next Steps (P1 continuation)
+1. Resolve Cosmos SDK v0.50 dependency tree
+2. Implement keeper logic with store operations
+3. Add proto definitions and code generation
+4. Wire modules into app.go
+5. Build oyd daemon
+6. Integration test: 9 Watchers bond, submit attestations, verify quorum
