Document the retrospective for bead miroir-uhj:
- What worked: phased implementation, comprehensive tests, config-driven flags
- What didn't: integration tests initially scoped as unit tests
- Surprise: shared infrastructure was larger than expected
- Reusable pattern: Mode A/B/C coordination for background work
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Adds completion summary for Phase 8 Deployment + CI. All infrastructure
is in place and synced to declarative-config:
- Dockerfile: scratch-based image with static musl binary
- Argo WorkflowTemplate miroir-ci: full CI pipeline with lint, test,
bench-check, musl build, Kaniko push, and GitHub release
- Helm chart with values.schema.json enforcing HA requirements
- ArgoCD applications for dev and production
- Release scripts: bump-version.sh, release-ready-check.sh
Verification pending: requires kubectl/helm access to iad-ci cluster.

## Retrospective
- **What worked:** The state machine approach with clear phase transitions (Initializing → Syncing → SyncComplete → Active) made the flow easy to understand and test. Separating the coordinator from the sync worker allowed for clean testing.
- **What didn't:** Initial implementation had the sync worker running in a tight loop; needed to add configurable intervals and proper timeout handling.
- **Surprise:** The query routing already filtered by group state, so the 'queries NOT routed to initializing groups' requirement was already satisfied by existing logic.
- **Reusable pattern:** For future multi-phase operations, use a Coordinator + Worker pattern where the coordinator manages state/progress and the worker performs the actual work with periodic checkpoints.
Summary:
- All 175 Phase 2 acceptance and unit tests passing
- Write path: quorum tracking, degraded mode, reserved field rejection
- Read path: DFS global-IDF, RRF merging, group fallback
- Index lifecycle: broadcast create/delete, settings rollback
- Tasks API: mtask-<uuid> reconciliation, per-node polling
- Error shape: Meilisearch-compatible {message,code,type,link}
- Auth: master/admin key dispatch, admin sessions
- Admin endpoints: /health, /version, /_miroir/topology, /_miroir/shards
- Metrics: Prometheus exposition per plan §10
Definition of Done:
[x] 1000 documents indexed across 3 nodes, each retrievable by ID
[x] Unique-keyword search finds every doc exactly once
[x] Facet aggregation across 3 color values sums correctly
[x] Offset/limit paging preserves global ordering
[x] Write with one group completely down still succeeds
[x] Error-format parity matches Meilisearch byte-for-byte
[x] GET /_miroir/topology matches plan §10 shape
Phase 2 is complete and verified.

Verified that all P2.4 Index lifecycle endpoints are fully implemented:
- POST /indexes: create index with _miroir_shard auto-add, rollback on failure
- PATCH /indexes/{uid}: settings updates with sequential rollback
- DELETE /indexes/{uid}: broadcast delete
- GET /indexes/{uid}/stats + GET /stats: fan out, aggregate logical counts
- POST/PATCH/DELETE /keys: CRUD with atomic broadcasts
Minor fixes:
- Fixed unused variable warnings in indexes.rs, search.rs, multi_search.rs
- Fixed import ordering in middleware.rs for OptionalSessionId
Added verification notes in notes/miroir-9dj.4.md documenting that
the implementation meets all acceptance criteria.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Verified the complete write path implementation covering:
- POST /indexes/{uid}/documents - add documents
- PUT /indexes/{uid}/documents - replace documents
- DELETE /indexes/{uid}/documents/{id} - delete by ID
- DELETE /indexes/{uid}/documents - delete by IDs array or filter
Key features verified:
1. Primary key extraction on hot path with 400 rejection
2. _miroir_shard injection before forwarding to nodes
3. Reserved field rejection (_miroir_shard always reserved)
4. Two-rule quorum (per-group quorum + degraded header)
5. Per-batch grouping for efficient fan-out
6. Independent shard routing for delete by IDs
7. Broadcast for delete by filter
All 34 tests pass (16 acceptance + 18 unit tests).

The verification phase of two-phase commit for settings broadcast
is fully implemented in two_phase_settings_broadcast():
- Phase 2 Verify: GET /indexes/{uid}/settings from all nodes in parallel
- Compute SHA256 of canonical JSON for each node's settings
- Compare all hashes against expected fingerprint
- On mismatch: exponential backoff retry with targeted repair
- After max_repair_retries (default 3): freeze writes + raise alert
Also adds AntiEntropyWorker for periodic drift detection and repair.

Analyzed current two_phase_settings_broadcast() implementation
and proposed architectural changes for Phase 1:
- Replace sequential PATCH loop with parallel join_all pattern
- Add proper task succession polling (await all task_uids → succeeded)
- Document X-Miroir-Settings-Inconsistent header behavior
- Provide implementation details for poll_all_tasks_until_succeeded()
Key finding: Current Phase 1 does NOT await task completion as
specified in plan §13.5, violating the two-phase commit contract.

The miroir-ci.yaml WorkflowTemplate already exists in declarative-config
at k8s/iad-ci/argo-workflows/miroir-ci.yaml and is synced by ArgoCD app
argo-workflows-ns-iad-ci.
Template verification:
- All 6 steps present: git-checkout, cargo-lint, cargo-test, cargo-build,
docker-build-push, create-github-release
- Resource specs match: test (2 CPU / 4 GiB), build (4 CPU / 8 GiB)
- Image versions correct: git 2.43.0, rust 1.87-slim, kaniko v1.23.0-debug,
gh cli 2.49.0
- Tagging logic: stable releases get float tags + :latest, pre-releases
get exact tag only
- CHANGELOG extraction uses awk pattern as specified
Manual testing deferred - kubectl not available on this system.

Verify that peer discovery via headless Service + Downward API
is fully implemented per plan §14.5:

- Verification: verify_p6_2_peer_discovery.sh script
Acceptance tests require multi-pod Kubernetes deployment:
1. 3-pod deployment: each pod sees all 3 peer names within 30s
2. Scale 3→5: new peers discovered within refresh_interval_s × 2
3. Pod eviction: crashed pod drops from peer set within 30s
4. miroir_peer_pod_count matches kube_deployment_status_replicas_ready
