Phase 1 gave us math; this phase turns the math into behavior a Meilisearch client sees as drop-in.

When all shards synced, mark group `active` — queries begin routing in round-robin\n5. Existing groups continue serving queries throughout (zero read interruption)\n\n## Why\n\nPlan §2 \"Adding a new replica group (throughput scaling)\": adding a group multiplies query capacity without touching existing groups' data.

Per-shard picks a different source so one group isn't hammered.\n\n**Write fan-out during sync**: new group already receives writes from step 3 onward. This is the durability guarantee — only the backfill window of historical data is transient.\n\n**Progress tracking**: per-shard cursor in `jobs` table; can be paused/resumed per Phase 6 Mode C.\n\n**Verification before `active`**: `GET /indexes/{uid}/stats` against new group → docs count within 0.1% of source group (allows for writes landing during sync).

Schedule background replication to restore RF within the group; degrade to cross-group fallback until restored\n\n## Why\n\nPlan §2: \"Changes to one group do not affect other groups' data or query routing.\" Group-removal is instant (no data movement) — lets operators shed throughput capacity without a migration window. Unplanned node failure is the most time-sensitive case: readers must not see errors; RF-restore runs in the background.\n\n## Details\n\n**Group-removal preconditions**: refuse to remove a group if it's the last group holding a shard (would be data loss). Require `--force` and document the risk.\n\n**Failure detection**: plan §4 config:\n```yaml\nhealth:\n interval_ms: 5000\n timeout_ms: 2000\n unhealthy_threshold: 3 # 3 consecutive failures → mark degraded\n recovery_threshold: 2 # 2 consecutive OKs → mark healthy again\n```\n\n**Cross-group fallback**: Phase 1 `covering_set` already deterministic per-request; the fallback is a per-shard \"if intra-group has none, check other groups\" decision **inside** the scatter planner (Phase 2).\n\n**RF-restore**: similar to P4.2 node addition but for an existing node that lost its data — re-run `_miroir_shard` filter migration from the best intra-group source.\n\n## Acceptance\n\n- [ ] Remove a group with healthy peer groups → queries route away within one `query_seq` tick; no read errors\n- [ ] `--force`-remove the last group holding shard S → loud warning; operator must re-type the index UID to confirm\n- [ ] RF=2 group with 1 node killed → reads succeed on remaining replica; `X-Miroir-Degraded` absent\n- [ ] RF=1 group with 1 node killed → cross-group fallback kicks in; `X-Miroir-Degraded` absent if fallback succeeds\n- [ ] Restored node re-hydrates from a peer replica within its group; `miroir_rebalance_in_progress` transitions 0→1→0","status":"open","priority":0,"issue_type":"task","created_at":"2026-04-18T21:31:43.887649468Z","created_by":"coding","updated_at":"2026-04-18T21:31:48.981354074Z","source_repo":".","compaction_level":0,"original_size":0,"labels":["phase-4"],"dependencies":[{"issue_id":"miroir-mkk.5","depends_on_id":"miroir-mkk","type":"parent-child","created_at":"2026-04-18T21:31:43.887649468Z","created_by":"coding","metadata":"{}","thread_id":""},{"issue_id":"miroir-mkk.5","depends_on_id":"miroir-mkk.1","type":"blocks","created_at":"2026-04-18T21:31:48.981335608Z","created_by":"coding","metadata":"{}","thread_id":""}]} {"id":"miroir-mkk.6","title":"P4.6 Admin API for topology ops: /_miroir/nodes + /_miroir/rebalance","description":"## What\n\nPlan §4 admin API endpoints for topology (wrap the rebalancer flows):\n- `POST /_miroir/nodes` — add node (P4.2)\n- `DELETE /_miroir/nodes/{id}` — drain + remove\n- `POST /_miroir/nodes/{id}/drain` — drain only (P4.3, plan §6 \"Scaling\" scale-down)\n- `POST /_miroir/rebalance` — manually trigger rebalance (e.g., after config-only topology tweak)\n- `GET /_miroir/rebalance/status` — current progress; returned shape includes per-shard phase + `miroir_task_id` for each migration batch\n\n## Why\n\nThese endpoints are the **operator surface**. Everything in §11 \"Common operations with miroir-ctl\" maps to these; the Admin UI §13.19 topology tab is a visual wrapper around the same endpoints.
