jedarden f07ba9575b repo hygiene: remove committed build artifacts and stale config.bak 
- Remove coverage/ directory (HTML and lcov files)
- Remove lcov.info and librust_out.rlib build artifacts
- Remove stray file '1' at repo root
- Remove dead config.bak/ module (unreferenced backup)
- Update .gitignore to exclude coverage/, lcov.info, and *.rlib patterns

Verified:
- No references to config.bak or librust_out in codebase
- cargo check --workspace compiles successfully
- notes/, .beads/, tests/, dashboards/ untouched

The plan promises four backward-compatibility commitments starting at v1.0:\n\n1. Meilisearch API compatibility layer: no breaking changes in minor versions\n2. `miroir-ctl` CLI flags: no incompatible changes in minor versions\n3. Config file schema: backward-compatible in minor versions (new fields always optional with defaults)\n4. Helm chart values schema: backward-compatible in minor versions\n\nDoc must:\n- Reproduce all four commitments verbatim.\n- Define what counts as a \"breaking change\" for each (e.g., a field rename is breaking; adding an optional field is not).\n- Document the deprecation policy (one minor cycle warning before removal).\n- Document the v0.x policy (MINOR bumps may include breaking changes — explicit, per §7).\n- Provide a CHANGELOG-tagging convention (e.g. `[breaking]` prefix for v1.x major-bump-required items).\n\n## Why\n\nThis is a written contract with users that today exists only as five lines in `plan.md`. Once we approach v1.0 we will need a reviewable, citable doc; releasing v1.0 without one is a liability for downstream integrators.\n\n## Acceptance\n\n- [ ] `docs/versioning-policy.md` exists with all four commitments\n- [ ] Defines \"breaking change\" per surface (API, CLI, config, Helm values)\n- [ ] Documents pre-1.0 vs post-1.0 policy difference\n- [ ] CHANGELOG.md preamble references the policy\n- [ ] README.md \"Stability\" section links to the policy\n\nParent epic: `miroir-uyx` (Phase 11 — Onboarding + Delivered Artifacts).","design":"","acceptance_criteria":"","notes":"","status":"closed","priority":2,"issue_type":"task","assignee":"claude-code-glm-4.7-bravo","created_at":"2026-05-10T02:35:00.288551019Z","updated_at":"2026-05-20T10:41:50.183432019Z","closed_at":"2026-05-20T10:41:50.183432019Z","close_reason":"Completed","source_repo":".","compaction_level":0,"labels":["phase-11"]}
{"id":"bf-1iw2","title":"P6.11 Vertical scaling escape valve (§14.10)","description":"## What\n\nSupport the §14.10 single-pod oversized mode for dev clusters / very small deployments / constrained environments. Operators may provision a single pod at higher limits (e.g. 4 vCPU / 8 GB); memory budgets scale linearly by multiplier; HPA may remain disabled.\n\nSpecifically:\n1. `values.schema.json` MUST allow `replicas: 1` with `taskStore.backend: sqlite` and `hpa.enabled: false` AND with `resources.limits.{cpu,memory}` larger than the §14.8 baseline.\n2. Document the multiplier behavior: when `resources.limits.memory` is N× the baseline, the in-Rust budgets (idempotency.max_cached_keys, session_pinning.max_sessions, etc.) should scale linearly OR the operator overrides each.\n3. `docs/horizontal-scaling/single-pod.md` documents this is supported, NOT recommended for production, and explains the fault-tolerance trade-offs (zero-downtime rollouts, pod-loss survival lost).\n\n## Why\n\n§14.10 promises this works. Currently nothing in `values.schema.json` rejects oversized single-pod, but nothing exercises it either; without explicit support, operators may have surprising memory-cap interactions when the runtime budgets don’t auto-scale.\n\n## Acceptance\n\n- [ ] Fixture in `tests/integration/` boots a single 4-vCPU / 8-GB pod successfully\n- [ ] `values.schema.json` accepts the oversized-single-pod combination\n- [ ] Memory-multiplier behavior documented (auto-scale or operator override) and one of the two implemented\n- [ ] `docs/horizontal-scaling/single-pod.md` includes the trade-off explanation from §14.10\n- [ ] README.md \"When to use\" section calls out single-pod as supported but not recommended\n\nParent epic: `miroir-m9q` (Phase 6 — Horizontal Scaling).","design":"","acceptance_criteria":"","notes":"","status":"closed","priority":2,"issue_type":"task","assignee":"claude-code-glm-4.7-bravo","created_at":"2026-05-10T02:34:26.505495761Z","updated_at":"2026-05-20T11:30:04.395654585Z","closed_at":"2026-05-20T11:30:04.395654585Z","close_reason":"Completed","source_repo":".","compaction_level":0,"labels":["phase-6"]}

Strip-on-response is implemented but reject-on-write is not.\n\n## Acceptance\n\n- [ ] POST/PUT `/indexes/{uid}/documents` containing `_miroir_shard` always returns 400 `miroir_reserved_field`\n- [ ] When `anti_entropy.enabled: true`, writes with client-supplied `_miroir_updated_at` are rejected; when disabled, the field is preserved end-to-end\n- [ ] When `ttl.enabled: true`, writes carrying `_miroir_expires_at` succeed (clients SET it); reads still strip it; when disabled, client values pass through\n- [ ] Error body matches Meilisearch shape `{message, code, type, link}` with `code: miroir_reserved_field`\n- [ ] Unit tests in `miroir-proxy/src/routes/documents.rs` cover all four matrix cells\n- [ ] Integration test confirms `_miroir_shard` injected by orchestrator passes write-validation (orchestrator stamping path is exempt)\n\nParent epic: `miroir-9dj` (Phase 2 — Proxy + API Surface).","design":"","acceptance_criteria":"","notes":"","status":"closed","priority":0,"issue_type":"task","assignee":"claude-code-glm-4.7-papa","created_at":"2026-05-10T02:33:14.466105436Z","updated_at":"2026-05-20T11:53:09.230425661Z","closed_at":"2026-05-20T11:53:09.230425661Z","close_reason":"Completed","source_repo":".","compaction_level":0,"labels":["phase-2"]}

This phase also wires the infrastructure pieces (ESO `ExternalSecret` and OpenBao integration) that depend on the ardenone-cluster OpenBao deployment.\n\n## Scope (plan §9)\n\n**Secret inventory — 9 entries**\n- `master_key` (client-facing)\n- `node_master_key` (Miroir → Meilisearch admin-scoped key)\n- `meilisearch_master_key` (per-node startup master key — fixed at process start)\n- `admin_api_key` (operators + miroir-ctl)\n- `ADMIN_SESSION_SEAL_KEY` (64-byte; seals Admin UI cookies via HMAC-SHA256 + XChaCha20-Poly1305; must be shared across multi-pod)\n- `SEARCH_UI_JWT_SECRET` (signs end-user JWTs; plus `SEARCH_UI_JWT_SECRET_PREVIOUS` during rotation)\n- `search_ui_shared_key` (only when `search_ui.auth.mode: shared_key`)\n- `ghcr_credentials` (Kaniko push)\n- `github_token` (gh CLI for Releases)\n- `redis_password` (optional)\n\n**Key relationship models**\n- Model A — shared master everywhere (dev/simple)\n- Model B — separated: clients use `master_key`; Miroir re-signs to `node_master_key` (recommended prod)\n\n**Rotations (zero-downtime where possible)**\n- `nodeMasterKey` (admin-scoped child of Meilisearch startup master): `POST /keys` new → update Secret → rolling restart → `DELETE /keys/{old_uid}`\n- Startup `MEILI_MASTER_KEY` is **not** zero-downtime (fixed at process start) — documented separately\n- `SEARCH_UI_JWT_SECRET` dual-secret overlap: primary + `_PREVIOUS`; 5-step rotation; recommended quarterly, on-leak-immediately shorten overlap; optional CronJob driving `miroir-ctl ui rotate-jwt-secret`\n- Search UI scoped Meilisearch key rotation (§13.21) — leader-coordinated with Redis hash, per-pod observation beacon, 120s drain before revocation\n\n**CSRF posture**\n- Admin UI: secure, HttpOnly, SameSite=Strict cookies; `X-CSRF-Token` double-submit on state-changing requests\n- Bearer tokens and `X-Admin-Key` bypass CSRF (can't be set by cross-origin HTML)\n- Origin checks: `admin_ui.allowed_origins` (default same-origin), `search_ui.allowed_origins`\n- SPA static GETs are CSRF-free\n\n**K8s Secret templates** (plan §9) — `miroir-secrets`, `meilisearch-secrets`, separate as needed\n\n**ESO ExternalSecret** (plan §6) — pulls from `kv/search/miroir` in OpenBao via `openbao-backend` ClusterSecretStore\n\n**miroir-ctl credential loading**\n- Priority: `MIROIR_ADMIN_API_KEY` env → `~/.config/miroir/credentials` TOML → `--admin-key` flag (flagged as script-unsafe)\n\n**Not handled (documented explicitly)** — tenant JWT tokens (forwarded to nodes as-is), per-index key scoping (forwarded unchanged), key creation API (broadcast)\n\n## Definition of Done\n\n- [ ] Every secret in the inventory has a Helm `values.yaml` hook + ESO `ExternalSecret` path or documented manual-only exception\n- [ ] Node-key rotation rehearsed end-to-end on a staging cluster within a single maintenance window without client impact\n- [ ] JWT rotation CronJob shipped with the chart at `suspend: true`;

Update ESO source / K8s Secret `miroir-secrets.nodeMasterKey` with the new key value.\n3. Rolling-restart Miroir pods so each pod picks up the new key. During rollout, old + new Miroir pods each use their own view; both views authenticate.\n4. Once all Miroir pods on new key, `DELETE /keys/{old_key_uid}` on every node.\n\n## Why\n\nPlan §9 is explicit: Meilisearch CE has **one startup master key** per process, fixed for the life of the process. The zero-downtime story is about **admin-scoped child keys** created via `POST /keys` — not the startup master. Clarifying this is the #1 source of confusion.\n\n## Details\n\n**Terminology clarification** (plan §9):\n- `MEILI_MASTER_KEY` (startup env var) — fixed at process start. Rotation REQUIRES process restart.\n- Admin-scoped child keys (via `POST /keys` with `actions: [\"*\"]`) — multiple can exist simultaneously.

Phase 1 gave us math; this phase turns the math into behavior a Meilisearch client sees as drop-in. Every downstream phase assumes these HTTP surfaces exist and return shapes that match the Meilisearch spec exactly, so §8 \"API compatibility tests\" can pin the contract from here on.\n\n## Scope (plan §3 Lifecycle + §5 API Surface)\n\n- `axum` server listening on `server.port` (default 7700) and metrics on 9090\n- **Write path** (plan §2 write path) — hash primary key, inject `_miroir_shard`, fan out to `RG × RF` nodes, per-group quorum (`floor(RF/2)+1`), `X-Miroir-Degraded` on any group missing quorum, 503 `miroir_no_quorum` only when no group met quorum for a shard\n- **Read path** (plan §2 read path) — pick group via `query_seq % RG`, build intra-group covering set, scatter, merge by `_rankingScore`, strip `_miroir_shard` always + `_rankingScore` if client didn't request, aggregate facets + estimatedTotalHits, report max processingTimeMs, group-fallback when a covering set has holes\n- **Index lifecycle** (plan §3) — create broadcasts + atomically injects `_miroir_shard` into `filterableAttributes`; settings sequential apply-with-rollback (§3 legacy; §13.5 replaces in Phase 5); delete broadcasts; stats aggregate `numberOfDocuments` + merge `fieldDistribution`\n- **Tasks** — per plan §3 task ID reconciliation; `GET /tasks`, `GET /tasks/{uid}`, `DELETE /tasks/{uid}`\n- **Error shape** — every error matches Meilisearch `{message,code,type,link}`; new `miroir_*` codes per plan §5\n- **Reserved fields contract** — `_miroir_shard` always-reserved; `_miroir_updated_at` / `_miroir_expires_at` reserved only when their feature flag is on (Phase 5)\n- **Auth** — master-key/admin-key bearer dispatch per §5 \"Bearer token dispatch\" rules 2–5; JWT path stubbed (Phase 5)\n- **/health + /version + /_miroir/ready + /_miroir/topology + /_miroir/shards** + **/_miroir/metrics** (admin-key gated mirror of port 9090 /metrics per plan §10)\n- **Middleware** — structured JSON log per plan §10; Prometheus metrics (`miroir_request_duration_seconds`, etc.)\n- **Scatter-gather dispatcher** — per-node retries with orchestrator-side retry cache keyed by `sha256(batch || target_node || idempotency_or_mtask)` (plan §4 note on `scatter.retry_on_timeout`)\n\n## Out of Scope (moved to later phases)\n\n- Two-phase settings broadcast (→ Phase 5 / §13.5)\n- Persistent task store (→ Phase 3)\n- Rebalancer (→ Phase 4)\n- Any §13 feature (→ Phase 5)\n- Multi-replica coordination / Redis / HPA (→ Phase 6)\n\n## Definition of Done\n\n- [ ] Integration test: 1000 documents indexed across 3 nodes, each retrievable by ID (plan §8)\n- [ ] Integration test: unique-keyword search finds every doc exactly once (plan §8)\n- [ ] Integration test: facet aggregation across 3 color values sums correctly (plan §8)\n- [ ] Integration test: offset/limit paging preserves global ordering (plan §8)\n- [ ] Integration test: write with one group completely down still succeeds on remaining group and stamps `X-Miroir-Degraded`\n- [ ] Error-format parity test: every `invalid_request`/`not_found`/`document_*` code matches Meilisearch output byte-for-byte on equivalent input\n- [ ] `GET /_miroir/topology` matches the shape in plan §10","design":"","acceptance_criteria":"","notes":"","status":"closed","priority":0,"issue_type":"epic","assignee":"claude-code-glm-4.7-bravo","created_at":"2026-04-18T21:18:33.148045077Z","created_by":"coding","updated_at":"2026-05-24T03:41:09.487273606Z","closed_at":"2026-05-24T03:41:09.487273606Z","close_reason":"Completed","source_repo":".","compaction_level":0,"original_size":0,"labels":["phase","phase-2"],"dependencies":[{"issue_id":"miroir-9dj","depends_on_id":"miroir-cdo","type":"blocks","created_at":"2026-04-18T21:23:08.570130243Z","created_by":"coding","metadata":"{}","thread_id":""}]}

Four properties that MUST be right:\n\n1. **Primary key extraction on the hot path** — plan §3 \"Primary key requirement\" says batches without a resolvable primary key are rejected before touching any node. This is a cheap, up-front check and a big UX win.\n2. **`_miroir_shard` injection** (plan §2 \"Inject `_miroir_shard`\") — every document gets `_miroir_shard: shard_id` added before forwarding. Stored as a filterable attribute (set at index creation), used by Phase 4 rebalancer and Phase 5 §13.8 anti-entropy for targeted shard retrieval. Stripped from all API responses.\n3. **Rejection of `_miroir_shard` in client-submitted docs** — plan §2 \"`_miroir_shard` is a reserved field name\": 400 `miroir_reserved_field` if present on the inbound doc.\n4. **Two-rule quorum** (plan §2):\n - Per-group quorum = `floor(RF/2) + 1` ACKs from that group's RF nodes\n - Write success if ≥ 1 group met its per-group quorum; `X-Miroir-Degraded` header if ANY group missed\n - HTTP 503 `miroir_no_quorum` only if NO group met its per-group quorum for a given shard\n\n## Details\n\n**Per-batch grouping** (plan §3 \"Ingest (add/replace)\"): group documents by target node set so each node gets exactly one HTTP request containing all the docs it owns. This minimizes HTTP fan-out count (critical at scale).\n\n**Retry-on-timeout** (plan §4 \"Note on `scatter.retry_on_timeout`\"): orchestrator-side retry cache keyed by `sha256(batch || target_node || idempotency_key_or_mtask_id)`.

Each node must return up to `offset + limit` results (plan §2 read path \"offset/limit\")\n5. Use P1.4 `merge` to collapse shard hits → single response\n\n## Why\n\nRead latency == max shard latency. This is where hedging (§13.2), adaptive replica selection (§13.3), and query coalescing (§13.10) will plug in during Phase 5 — so the routing decisions need to be factored cleanly into a `ScatterPlan` now rather than hard-wired.\n\n## Details\n\n**`showRankingScore: true` is injected unconditionally** so the merger can global-sort.

Parseable-but-invalid → 401 `miroir_jwt_invalid`. Signature-valid but scope mismatch → 403 `miroir_jwt_scope_denied`. Phase 5 §13.21 adds the JWT validation; Phase 2 stubs this to \"not-a-jwt → next step\"\n2. **Admin-path opaque-token match** — path starts with `/_miroir/`, match against `admin_key`. Exempt: `/_miroir/metrics`, `/_miroir/ui/search/locale/*`, `POST /_miroir/admin/login`, `GET /_miroir/ui/search/{index}/session`\n3. **Master-key match** — other paths → `master_key`\n4. **Mismatch** → 401 `miroir_invalid_auth`\n5. **Dispatch-exempt endpoints** — exhaustive list in plan §5 rule 5\n\nPlus: `X-Admin-Key` short-circuit for admin endpoints.\n\n## Why\n\nPlan §5: \"Three token types can appear on `Authorization: Bearer <value>` simultaneously — the `master_key`, the `admin_key`, and a search UI JWT.

{"id":"miroir-b64","title":"Genesis: Miroir Implementation","description":"## Genesis Bead\n**Tied to plan:** `/home/coding/miroir/docs/plan/plan.md`\n\n## Project Overview\n\n**Miroir** — _Multi-node Index Replication Orchestrator, Integrated Rebalancing_ — is a RAID-like sharding and high-availability layer for **Meilisearch Community Edition (MIT)**. It stripes a large index across a fleet of Meilisearch nodes, fans out search queries across all shards, merges ranked results, and rebalances shard assignments when nodes are added or removed — all without Meilisearch Enterprise.\n\n## Why This Exists\n\nMeilisearch CE loads its entire index into memory-mapped LMDB files. A large index that exceeds a single server's available RAM cannot run on that server. The Enterprise Edition's native sharding and replication are **BUSL-1.1 gated** — production use requires a commercial license. Miroir solves this using only the Meilisearch **public REST API**, with no node-side patches or forks. Every Meilisearch node continues to run unmodified CE.\n\n## Design Principles (from plan §1)\n\n1. **Invisible federation** — clients talk to one endpoint using the standard Meilisearch API\n2. **No Enterprise dependency** — pure CE (MIT) everywhere\n3. **Rendezvous hashing (HRW)** — matches what Meilisearch Enterprise itself uses internally\n4. **RF-configurable redundancy** — RF=1 capacity, RF=2 one-node-loss, RF=3 two-node-loss\n5. **Graceful degradation** — partial results with `X-Miroir-Degraded` beats whole-request failure\n6. **Static binaries, scratch images** — musl + scratch Docker, trivial deploy, tiny attack surface\n7. **GitOps first** — all config in `jedarden/declarative-config`, ArgoCD drives cluster changes\n8. **Fixed per-pod resource envelope (2 vCPU / 3.75 GB)** — scale out, not up\n\n## Architecture (high-level)\n\n- **Shards (S)** — logical hash-space granularity, **fixed at index creation**, `S = max_nodes_per_group_ever × 8`\n- **Replica Groups (RG)** — independent query pools, each holds a full copy of all shards; scales **read throughput**\n- **Replication Factor (RF)** — intra-group copies per shard; scales **HA within a group**\n- **Writes** fan out to `RG × RF` nodes (one per-group quorum, cluster-wide success when ≥1 group met its quorum)\n- **Reads** target exactly one group per query (round-robin); fan out to that group's covering set only\n- **Rendezvous hashing is scoped to each group** — prevents cross-group coverage gaps\n\n## Phase Plan\n\n- [ ] **Phase 0 — Foundation** — Cargo workspace, crate layout, config schema, dependencies\n- [ ] **Phase 1 — Core Routing** (plan §2, §4) — rendezvous hash, topology, write targets, covering set\n- [ ] **Phase 2 — Proxy + API Surface** (plan §3, §5) — HTTP server, documents/search/indexes/settings/tasks/health, result merger, quorum, error mapping\n- [ ] **Phase 3 — Task Registry + Persistence** (plan §4 task store) — SQLite schema (14 tables), Redis mirror for HA\n- [ ] **Phase 4 — Topology Operations** (plan §2 topology changes, §4 rebalancer) — add/remove node, add/remove group, drain, dual-write, shard-filter migration\n- [ ] **Phase 5 — Advanced Capabilities** (plan §13, subsections .1–.21) — reshard, hedging, EWMA, query planner, two-phase settings, session pinning, aliases, anti-entropy, streaming dump import, idempotency+coalescing, multi-search, vector, CDC, TTL, tenant affinity, shadow tee, ILM, canaries, Admin UI, Explain, Search UI\n- [ ] **Phase 6 — Horizontal Scaling + HPA** (plan §14) — pod envelope, request-path statelessness, Mode A/B/C background coordination, peer discovery, HPA spec\n- [ ] **Phase 7 — Observability + Ops** (plan §10) — metrics, tracing, logs, alerts, Grafana dashboard, ServiceMonitor\n- [ ] **Phase 8 — Deployment + CI** (plan §6, §7) — Dockerfile (scratch+musl), Helm chart, ArgoCD Application, Argo Workflow template\n- [ ] **Phase 9 — Testing** (plan §8) — unit, integration (docker-compose), compatibility, chaos, performance (criterion), SDK smoke tests\n- [ ] **Phase 10 — Security + Secrets** (plan §9) — sealed secrets, ESO/OpenBao integration, key rotation (admin-scoped, JWT, scoped-key), CSRF posture\n- [ ] **Phase 11 — Onboarding + Docs + Delivered Artifacts** (plan §11, §12) — README, CHANGELOG, migration docs, miroir-ctl help, runbooks, release checklist\n- [ ] **Phase 12 — Open Problems Tracking** (plan §15) — score normalization at scale validation, arm64 support, Raft-based HA task state exploration\n\n## How to use this bead\n\n- Each phase has its own epic bead that blocks this genesis bead\n- Every phase epic decomposes into concrete task beads; most tasks have subtasks\n- Dependencies are wired so ready-work can be discovered with `br ready`\n- Close phase epics as they complete; update the checklist above by editing this bead's body\n- Close this genesis bead only when all phases are complete AND `br ready` returns empty\n\n## Cross-cutting references\n\n- Infrastructure: Hetzner EX44 + Tailscale + iad-ci Argo Workflows (see `/home/coding/CLAUDE.md`)\n- Container registry: `ghcr.io/jedarden/miroir`\n- Helm chart

{"id":"miroir-cdo","title":"Phase 1 — Core Routing (rendezvous hash, topology, covering set)","description":"## Phase 1 Epic — Core Routing\n\nImplements the deterministic, coordination-free routing primitives that everything else depends on. After this phase, given a fixed topology + config, any Miroir pod can independently compute identical write targets and covering sets — no coordination required.\n\n## Why This Matters\n\nPlan §1 principle 3: rendezvous hashing (HRW) is the same algorithm Meilisearch Enterprise uses internally with twox-hash. Getting this right has **three** properties we rely on downstream:\n\n1. **Determinism** — all pods agree on assignments without any gossip protocol\n2. **Minimal reshuffling** — adding a node to a group moves only ~1/(Ng+1) of that group's docs (plan §2 \"Properties\" bullets)\n3. **Group isolation** — hashing scoped to intra-group node lists prevents both replicas of a shard from landing in the same group (plan §2 \"Why group-scoped assignment matters\")\n\nThese properties are the foundation for the §2 write path, §2 read path, §4 rebalancer, §13.3 adaptive selection, §13.4 query planner, §13.8 anti-entropy, and §14.5 Mode A shard-partitioned ownership. A subtle bug here — e.g., seeding the hash differently, using a non-stable node-id encoding — corrupts every later layer silently.\n\n## Scope (plan §2 Architecture + §4 router.rs)\n\n- `router.rs` — `score(shard, node)`, `assign_shard_in_group`, `write_targets`, `query_group`, `covering_set`, `shard_for_key`\n- `topology.rs` — `Topology` struct (nodes grouped by `replica_group`), node health state machine (healthy / degraded / draining / failed / joining / active / removed)\n- `scatter.rs` — fan-out orchestration primitives (stubbed execution; wired in Phase 2)\n- `merger.rs` — result merge primitives (global sort by `_rankingScore`, offset/limit, facet aggregation, estimatedTotalHits summation, `_miroir_shard` + `_rankingScore` stripping) — pure-function friendly for unit testing\n- Unit tests per §8 \"Router correctness\" + \"Result merger\" bullets\n\n## Definition of Done\n\n- [ ] Rendezvous assignment is deterministic given fixed node list (verified by test)\n- [ ] Adding a 4th node in a 3-node group moves at most ~2 × (1/4) of shards (verified by test, plan §8)\n- [ ] 64 shards / 3 nodes / RF=1 → each node holds 18–26 shards (verified by test)\n- [ ] Top-RF placement changes minimally on add / remove (verified by test)\n- [ ] `write_targets` returns exactly `RG × RF` nodes, one from each group\n- [ ] `query_group(seq, RG)` distributes evenly (verified by test)\n- [ ] `covering_set` within a group returns exactly one node per shard (with intra-group replica rotation)\n- [ ] `merger` passes the merge/facet/limit tests in plan §8\n- [ ] `miroir-core` ≥ 90% line coverage via cargo-tarpaulin (per §8 coverage policy)","design":"","acceptance_criteria":"","notes":"","status":"closed","priority":0,"issue_type":"epic","assignee":"claude-code-glm-4.7-bravo","created_at":"2026-04-18T21:18:33.134146061Z","created_by":"coding","updated_at":"2026-05-23T23:04:32.270694677Z","closed_at":"2026-05-23T23:04:32.270694677Z","close_reason":"Phase 1 — Core Routing verified complete with additional improvements.\n\n## Retrospective\n- **What worked:** Phase 1 was already fully implemented with comprehensive test coverage (145 tests across router, topology, scatter, and merger modules).

Any deviation (different seed, different ordering, endianness) forks routing across any two Miroir instances and silently corrupts writes.\n\n## Design Notes (plan §2 / §4)\n\n- **Hash function is `twox-hash` (XxHash family)** — the same one Meilisearch Enterprise uses; the choice is non-negotiable (plan §2).\n- **Node-id encoding stability** — the string passed to `node_id.hash(&mut h)` must be byte-stable. Use the bare `id: \"meili-0\"` string from config, not a reformatted address.\n- **`assign_shard_in_group` is group-scoped on purpose** — per plan §2 \"Why group-scoped assignment matters\": scoping to the group prevents both replicas of a shard from landing in the same group.

State transitions correspond to plan §2 topology-change verbs: a node is `Joining` → `Active` after a group-add migration; `Draining` → `Removed` after a node-remove migration; `Failed` is for unplanned loss.\n\nThe state field matters for **routing-eligibility**: writes skip `Draining` for *affected* shards (plan §2 \"Removing a node\" step 1), but still deliver to it for shards it still owns.

Returns `RG × RF` nodes total (may include duplicates across groups if a node_id coincidentally has the highest score in multiple groups — use a dedup pass in the HTTP layer when grouping docs per-request rather than dedup here, so the routing layer's behavior is pure).\n\n**`query_group`** — round-robin per the plan's note: \"`query_sequence_number` is a per-pod counter, not a cluster-wide one.\" Under HPA, cluster-wide balance relies on the K8s Service's round-robin / random kube-proxy policy (§14.4 link).\n\n**`covering_set`** — one node per shard within a group. The intra-group replica selection within each shard rotates by `query_seq % rf` (plan §4 code sample). The returned set is **deduplicated** because one node may own multiple shards in the same group; searching it once captures all its shards (Meilisearch searches all its local docs in a single call).\n\n## Critical Invariant\n\nTwo different Miroir pods, given identical `Topology` + `rf` + `shard_count`, **must** compute the same `write_targets` for any given `shard_id` and the same `covering_set` modulo `query_seq` rotation. This is the property that makes the request path stateless (plan §14.4).\n\n## Acceptance (plan §8)\n\n- [ ] `write_targets` returns exactly `RG × RF` nodes (counting duplicates)\n- [ ] `write_targets` assigns one-per-group: the subset of returned nodes in group g is exactly `assign_shard_in_group(shard, group_g_nodes)`\n- [ ] `covering_set` has `|covering_set| ≤ Ng` and covers all `shard_count` shards within the chosen group\n- [ ] Two instances of `Topology` with identical content produce identical `covering_set` outputs for the same `query_seq`\n- [ ] `query_group` distribution: 10K `query_seq` values `% RG` produce uniformly distributed group choices (chi-square pass)","design":"","acceptance_criteria":"","notes":"","status":"closed","priority":0,"issue_type":"task","created_at":"2026-04-18T21:26:11.798428290Z","created_by":"coding","updated_at":"2026-05-13T23:11:21.452413438Z","closed_at":"2026-05-13T23:11:21.452413438Z","close_reason":"Completed","source_repo":".","compaction_level":0,"original_size":0,"labels":["phase-1"],"dependencies":[{"issue_id":"miroir-cdo.3","depends_on_id":"miroir-cdo.1","type":"blocks","created_at":"2026-04-18T21:26:21.555076342Z","created_by":"coding","metadata":"{}","thread_id":""},{"issue_id":"miroir-cdo.3","depends_on_id":"miroir-cdo.2","type":"blocks","created_at":"2026-04-18T21:26:21.576939978Z","created_by":"coding","metadata":"{}","thread_id":""}]}

Every §13 feature's \"Scaling mode\" column in plan §14.6 gets wired up here — Phase 5's implementations have to already understand they'll run inside one of the three modes.\n\n## Scope\n\n**14.1–14.3 — Per-pod envelope**\n- `resources.requests` = 500m / 1Gi; `resources.limits` = 2000m / 3584Mi\n- Per-feature memory row validated against plan §14.2 budget\n- CPU budget per plan §14.3 (~3 kQPS/pod small responses)\n\n**14.4 — Request path HPA**\n- `autoscaling/v2` HPA on CPU 70%, memory 75%, `miroir_requests_in_flight` as `type: Pods` `AverageValue: 500`, `miroir_background_queue_depth` as `type: External` `Value: 10` (plan §14.4 note on metric types)\n- `prometheus-adapter` as a chart prerequisite when HPA is enabled\n- `values.schema.json` rejects `hpa.enabled=true` without `replicas >= 2 AND taskStore.backend = redis`\n\n**14.5 — Background coordination modes**\n- **Mode A — Shard-partitioned ownership** (anti-entropy §13.8, settings-drift check §13.5, task registry pruner, TTL sweeper §13.14, canary runner §13.18)\n- **Mode B — Leader-only lease** (reshard coordinator §13.1, rebalancer Phase 4, alias flip serializer §13.7, two-phase settings broadcast §13.5, ILM evaluator §13.17, scoped-key rotation leader §13.21)\n- **Mode C — Work-queued chunked jobs** (streaming dump import §13.9, large reshard backfill §13.1)\n- **Peer discovery** via headless Service (`miroir-headless`) + Downward API `POD_NAME`/`POD_IP`, 15s SRV refresh\n- Rendezvous over peer set for Mode A; `SET NX EX 10` renewed every 3s for Mode B\n- Job lease heartbeat every 10s with 30s timeout for Mode C\n\n**14.6 — Per-feature scaling-mode wiring** — 21 rows, each must compile against the chosen mode\n\n**14.7 — Deployment sizing matrix** — ops documentation/tooling surfacing orchestrator pod count vs. corpus × QPS tiers\n\n**14.8 — Resource-aware defaults** — every config knob's default sized for the envelope\n\n**14.9 — Resource-pressure metrics + alerts** — `miroir_memory_pressure`, `miroir_cpu_throttled_seconds_total`, `miroir_request_queue_depth`, `miroir_background_queue_depth{job_type}`, `miroir_peer_pod_count`, `miroir_leader`, `miroir_owned_shards_count`; PrometheusRule alerts\n\n**14.10 — Vertical-scaling escape valve** — documented as supported but not recommended; no implementation work, just docs\n\n## Definition of Done\n\n- [ ] Multi-pod deployment (replicas=3) — every pod independently serves requests with identical routing\n- [ ] Kill one of three pods mid-traffic — zero client-visible errors beyond retry budget (plan §8 chaos)\n- [ ] Mode A test: spin up 3 pods, anti-entropy runs exactly once per shard per interval cluster-wide\n- [ ] Mode B test: start 3 pods, exactly one holds the reshard lease at any given instant; killing it promotes another within `lease_ttl_s`\n- [ ] Mode C test: submit a 10GB dump; chunks distribute across 3 pods and HPA reacts to `miroir_background_queue_depth`\n- [ ] All §14.2 memory rows fit within 3584 MiB under realistic steady-state load\n- [ ] All §14.9 alerts present in the PrometheusRule manifest and trip under induced fault","design":"","acceptance_criteria":"","notes":"","status":"closed","priority":0,"issue_type":"epic","assignee":"marathon","created_at":"2026-04-18T21:21:13.549727274Z","created_by":"coding","updated_at":"2026-05-25T08:21:20.124807899Z","closed_at":"2026-05-25T08:21:20.124807899Z","close_reason":"Phase 6 epic verified complete.

Without this phase, Miroir is a static sharder — useful but not production-grade. Elasticity is what justifies the complexity of the whole system.\n\nPlan §15 Open Problem 1 (dual-write race) is partially mitigated by careful sequencing here and fully closed by §13.8 anti-entropy in Phase 5.

Admin API: `POST /_miroir/nodes` body `{\"id\": \"meili-N\", \"address\": \"...\", \"replica_group\": G}`\n2. Mark `joining`\n3. Recompute assignments — `affected_shards` where `meili-N` enters the top-RF within group G\n4. **Dual-write**: new inbound writes for affected shards go to **both** old owner and new node (idempotent — Meilisearch PUT semantics handle dupes via primary key)\n5. For each affected shard, background migration via the shard-filter primitive (plan §4):\n ```\n GET /indexes/{uid}/documents?filter=_miroir_shard={shard_id}&limit=1000&offset=0\n GET /indexes/{uid}/documents?filter=_miroir_shard={shard_id}&limit=1000&offset=1000\n ... until exhausted\n ```\n6. Write each page to the new node (docs already carry `_miroir_shard`)\n7. Mark `active`; stop dual-write\n8. Delete migrated shard from old node: `POST /indexes/{uid}/documents/delete {\"filter\": \"_miroir_shard = {shard_id}\"}`\n9. Documents on unaffected shards never touched\n\n## Why\n\nPlan §1 principle 4 (RF-configurable redundancy) + §2 \"Three independent scaling dimensions\" depend on this. The `_miroir_shard` filter primitive is what makes migration move only `~total_docs/(N+1)` docs instead of `total_docs` — a 10–100× reduction in I/O vs. a naive \"copy everything then diff\" approach.\n\n## Details\n\n**Dual-write durability invariant**: between steps 4 and 7, every accepted write for the affected shards lands on both old and new. If dual-write is skipped while migration is running, writes arriving at that exact moment may land only on the old owner and be lost when step 8 deletes. Plan §15 Open Problem 1 is the remaining race; §13.8 anti-entropy (Phase 5) is the safety net.\n\n**Pagination cursor**: `offset` is the simplest, but Meilisearch `limit + offset` has an internal cap (default 1000 + 0 → max ~20 for safe). Configure `pagination.maxTotalHits` per-node at index creation to allow deep pagination (safe: we're just iterating our own injected shard).\n\n**Per-page batch**: `rebalancer.migration_batch_size` (default 1000) — one page read + one page write per cycle.\n\n**Fail-open behavior**: if the source node becomes unavailable mid-migration, the rebalancer pauses this shard; other shards continue.

Mark `removed`\n5. `DELETE /_miroir/nodes/{id}` actually removes from config; operator deletes pod + PVC out-of-band\n\n## Why\n\nPlan §2: \"movement: ~RF/Ng of that group's documents\" on removal. The drain API decouples \"stop taking writes\" (immediate) from \"delete the pod\" (operator decision) — gives operators room to verify before committing to hardware loss.\n\n## Details\n\n**Order matters**: drain → remove. `drain` is reversible (mark `active` again); `remove` is not. CLI (`miroir-ctl node drain meili-2` per plan §11) should pause and await confirmation before the remove step.\n\n**Still readable during drain**: reads that previously routed to the draining node still work — the node is not down, just not accepting new writes for the affected shards.

Background sync: for each shard, copy all docs from **any** healthy existing group to the new group's nodes via `filter=_miroir_shard={id}` pagination; new inbound writes already fan out to the new group immediately\n4. 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. This is the primary \"we need more search QPS\" lever. Unlike intra-group rebalance which moves a subset, group-add **copies** every shard to the new group — so the I/O is proportional to total corpus size, not `1/(Ng+1)`.\n\n## Details\n\n**Source group selection**: round-robin across existing `active` groups to spread read load during sync.

{"id":"miroir-mkk.5","title":"P4.5 Group removal + unplanned node failure","description":"## What\n\nTwo related flows from plan §2:\n\n**Removing a replica group** (decommission a query pool):\n1. Mark group `draining` — queries stop routing immediately\n2. Nodes can be decommissioned; no data migration needed (other groups hold the docs)\n3. Remove nodes from config; operator deletes pods + PVCs\n\n**Unplanned node failure**:\n1. Health check detects failure → mark `failed`, stop routing writes to it\n2. If RF > 1 within the group: surviving replicas serve reads — no immediate migration\n3. For reads: if failed node's shards have no intra-group RF replica, fall back to a healthy group for those shards\n4. 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","design":"","acceptance_criteria":"","notes":"","status":"closed","priority":0,"issue_type":"task","assignee":"marathon","created_at":"2026-04-18T21:31:43.887649468Z","created_by":"coding","updated_at":"2026-05-24T23:18:17.529860776Z","closed_at":"2026-05-24T23:18:17.529860776Z","close_reason":"Implemented RF-restore for node recovery (P4.5).

Every §13 advanced capability and §14 HA mode consumes one or more of these tables, so settling the schema here prevents per-feature bespoke persistence.\n\n## Why This Happens Before §13 / §14\n\n- Plan §4 explicitly says \"Every table below is defined here and cross-referenced from the §13 / §14.5 section that consumes it.\"\n- Without `tasks`, any write that returns a `miroir_task_id` is ephemeral — a pod restart would lose every in-flight task (plan §3 task-id reconciliation paragraph).\n- Multi-pod HPA in Phase 6 **requires** Redis (plan §14.4 — Helm schema rejects `replicas > 1` + `taskStore.backend: sqlite`). Getting the Redis keyspace right now is cheaper than retrofitting.\n\n## Scope — the 14 tables and 14 Redis keyspaces (plan §4)\n\n1. `tasks` — Miroir task registry (miroir_id → node_tasks map + status)\n2. `node_settings_version` — per-(index, node) settings freshness (for §13.5 + `X-Miroir-Min-Settings-Version`)\n3. `aliases` — single-target + multi-target (`kind`, `current_uid`, `target_uids`, `version`, `history`)\n4. `sessions` — read-your-writes session pins (§13.6)\n5. `idempotency_cache` — write dedup (§13.10)\n6. `jobs` — work-queued background jobs (§14.5 Mode C)\n7. `leader_lease` — singleton-coordinator lease (§14.5 Mode B; SQLite advisory lock substitute for single-replica)\n8. `canaries` — canary definitions (§13.18)\n9. `canary_runs` — canary run history (§13.18)\n10. `cdc_cursors` — per-(sink, index) CDC cursor (§13.13)\n11. `tenant_map` — API-key → tenant mapping (§13.15 `api_key` mode)\n12. `rollover_policies` — ILM rollover policies (§13.17)\n13. `search_ui_config` — per-index search-UI config (§13.21)\n14. `admin_sessions` — Admin UI session registry (§13.19)\n\n## Redis keyspace mirror (plan §4 \"Redis mode (HA)\")\n\nEvery table above mapped to a hash + `_index` secondary set so list-wide queries are O(cardinality) without `SCAN`.

The trait exposes per-table operations plus a generic `migrate(&self) -> Result<()>` that creates tables idempotently and records a `schema_version` row for upgrade detection.\n\n**Non-obvious**:\n- `tasks.node_tasks` is JSON — use a `serde_json::Value` column, not a stringly-typed hack\n- `aliases.history` is a JSON array bounded by `aliases.history_retention`; enforce bound on `UPDATE`\n- `idempotency_cache.body_sha256` is a `BLOB`, not TEXT — 32 raw bytes\n- `jobs.claim_expires_at` updated by heartbeat every 10s; pod loss → claim expires → another pod picks up\n- `leader_lease` for SQLite is an advisory-lock substitute (persist the row, interpret its presence semantically)\n\n**Idempotent migrations** — use `CREATE TABLE IF NOT EXISTS` + a `schema_versions` table that records each applied migration.

Each node stores full vector for its own docs.\n- **Embedder config** is a setting → §13.5 two-phase broadcast ensures all nodes have identical embedders; §13.8 anti-entropy repairs drift.\n- **Read**: scatter with **over-fetch factor** (default 3×). Per-shard `limit = requested_limit × over_fetch_factor`, return both `_semanticScore` and `_rankingScore` (Meilisearch hybrid exposes both).\n- **Merger**: combine into global score via RRF or convex `(1−α)·bm25 + α·semantic`, matching Meilisearch's hybrid formula. Global sort → apply offset/limit.\n- **Pure vector** uses `_semanticScore` only; **pure keyword** uses `_rankingScore` only.\n\nOver-fetch tunable per request via `X-Miroir-Over-Fetch` header.\n\n## Why\n\nPlan §13.12: \"Naïve top-K merging across shards produces wrong global rankings: a shard with few semantically-relevant documents returns low scores that compete badly against a dense shard's high scores.\" Over-fetch is the only way to recover correct global ranking for sparse semantic matches.\n\n## Details\n\n**Embedder drift metric**: `miroir_vector_embedder_drift_total` — distinct embedders detected across nodes.

Writes are never hedged (duplicates produce extra Meilisearch tasks + potential auto-ID dupes).\n\n## Why\n\nPlan §13.2: \"A scatter-gather query's latency is bounded by the slowest responding shard. A single GC-paused or disk-throttled node poisons p99 across the whole fleet.\" Hedging trades a small cost (occasional extra node request) for a large win (tail latency roughly halved on skewed workloads).\n\n## Details\n\n**Config** (plan §13.2):\n```yaml\nhedging:\n enabled: true\n p95_trigger_multiplier: 1.2\n min_trigger_ms: 15\n max_hedges_per_query: 2\n cross_group_fallback: true\n```\n\n**Idempotency**: reads are side-effect-free, so no cache needed. Just race.\n\n**Scaling mode**: stateless per-request; each pod hedges its own requests independently.\n\n**Interaction with §13.3**: hedging reads the per-node p95 from the same EWMA registry §13.3 writes to.\n\n## Acceptance\n\n- [ ] Chaos test: `tc netem delay 500ms` on one of 3 nodes; hedged fan-out avoids the slow node via the other 2 replicas; p95 close to healthy-cluster p95\n- [ ] Write path verified NOT to hedge (no duplicate node task IDs under any scenario)\n- [ ] `miroir_hedge_fired_total{outcome=winner|loser}` counters tick in test runs\n- [ ] `max_hedges_per_query` cap prevents thundering herd under widespread node degradation","design":"","acceptance_criteria":"","notes":"","status":"closed","priority":1,"issue_type":"task","assignee":"marathon","created_at":"2026-04-18T21:33:36.758491853Z","created_by":"coding","updated_at":"2026-05-25T03:12:22.104980984Z","closed_at":"2026-05-25T03:12:22.104980984Z","close_reason":"Implemented tail-latency hedging for reads using tokio::time::timeout.

Per-index config via `POST /_miroir/ui/search/{index}/config`.\n\n**Capabilities**: instant-search (150ms debounce + §13.10 coalescing), combined multi-search per keystroke (§13.11), URL state (bookmarkable), keyboard nav, highlighting, typo-tolerance UI, empty state + \"did you mean,\" pagination, dark mode, i18n via `GET /_miroir/ui/search/locale/{lang}.json`.\n\n**Embeddable modes**: iframe, web component (`<miroir-search index=\"products\">`), headless (no chrome).\n\n## Auth Model — Two-Layer Credential Chain\n\n1. **Scoped Meilisearch key** (orchestrator-held, rotated). Created per-index with `actions: [\"search\"]` scope. Hard expiration `scoped_key_max_age_days` (60d); auto-rotated `scoped_key_rotate_before_expiry_days` (30d) before expiry.\n\n **Rotation coordination**: Redis hash `miroir:search_ui_scoped_key:<index>` {primary_uid, previous_uid, rotated_at, generation}; leader lease `search_ui_key_rotation:<index>`; per-pod beacon `miroir:search_ui_scoped_key_observed:<pod>:<index>` with 60s TTL.

Drain wait `scoped_key_rotation_drain_s` (120s).\n\n2. **Short-lived JWT** (browser-held, 15-min default). `GET /_miroir/ui/search/{index}/session` mints a JWT signed by `SEARCH_UI_JWT_SECRET`. Claims: `iss=miroir`, `sub=search-ui-session`, `idx=<uid>`, `scope=[search, multi_search, beacon]`, `exp`, `iat`, `kid`, optional `injected_filter`. SPA then calls `/indexes/{uid}/search` with `Authorization: Bearer <jwt>`; orchestrator validates + **substitutes scoped key** before forwarding.\n\n **Scope + idx check** (defense-in-depth): validate on every request before any node call; (method, path) must match action in scope AND `idx` must equal target index. Else `miroir_jwt_scope_denied` (403).\n\n3. **Auth modes**: `public` (rate-limited by IP), `shared_key` (requires `X-Search-UI-Key`), `oauth_proxy` (upstream `X-Forwarded-User/Groups` headers).\n\n4. **Filter injection in oauth_proxy mode**: `filter_template: \"tenant IN [{groups}]\"` rendered at session-mint, baked into JWT, ANDed with user-supplied filter on every search.

These are research/validation/future-enhancement beads, not blockers for v1.0. This phase does not block the genesis bead's shipping path — it's a parallel track that persists beyond v1.0.\n\n## Why An Epic At All\n\nPlan §15 flags these as \"documented constraints, not blockers. Initial release ships with known limitations.\" Tracking them as beads means they're not forgotten, they have a visible owner, and their resolution status can be surfaced alongside the rest of the work.\n\n## Scope — the 6 Open Problems (plan §15)\n\n1. **Shard migration write safety** — OP#1. **Status: partially addressed.** Dual-write cutover sequencing (Phase 4) + anti-entropy reconciler (§13.8 / Phase 5) catches slipped docs. Remaining work: chaos-test the cutover boundary, document any reproducible window where data could be lost if anti-entropy is disabled.\n\n2. **Task state HA (Raft vs. Redis)** — OP#2. **Status: deferred.** Current: Redis for multi-pod, SQLite for single-pod. Future: lightweight in-process Raft (or equivalent) so Redis is not required in HA. Not v1.x.\n\n3. **Resharding (S change) vs. node scaling (N change)** — OP#3. **Status: addressed by §13.1** (shadow-index dual-hash). Remaining work: empirical validation of the §13.1 \"2× transient storage and write load\" caveat under real corpora; schedule guidance in the CLI for off-peak reshard windows.\n\n4. **Score normalization at scale** — OP#4. **Status: settings-divergence addressed by §13.5 two-phase broadcast + drift reconciler.** Remaining work is purely statistical: validate that `_rankingScore` remains comparable across shards with very different document-count distributions. Requires corpus diversity tests.\n\n5. **Dump import distribution** — OP#5. **Status: addressed by §13.9 streaming routed dump import.** Broadcast mode retained as fallback. Remaining work: identify and enumerate every dump variant `mode: streaming` cannot fully reconstruct; either extend streaming or document the fallback trigger clearly.\n\n6. **arm64 support** — OP#6. **Status: not planned for v0.x.** Wire into CI when K8s ARM node support is actually needed (likely v1.x or later).\n\n## How To Use This Phase\n\n- Each OP becomes a child bead (bug/feature type) under this epic\n- Beads stay open until the status column above says \"fully addressed\"\n- v1.0 release notes should explicitly link to this epic so operators know what's still on the table\n- New open problems discovered during implementation get added here rather than silently accreted elsewhere\n\n## Not In Scope\n\n- Any concrete implementation work already covered by §13.1 / §13.5 / §13.8 / §13.9 — that belongs to Phase 5.","design":"","acceptance_criteria":"","notes":"","status":"closed","priority":2,"issue_type":"epic","assignee":"claude-code-glm-4.7-alpha","created_at":"2026-04-18T21:22:54.403910669Z","created_by":"coding","updated_at":"2026-05-08T19:24:51.358651712Z","closed_at":"2026-05-08T19:24:51.358651712Z","close_reason":"Phase 12 epic setup complete.

Start 3-node cluster, write 1000 docs\n2. Trigger node addition (`POST /_miroir/nodes`)\n3. During dual-write, rapid-fire new writes with tight (1ms) interval\n4. Tight-loop the transition from step 4 (migration complete) to step 7 (old replica deleted)\n5.

Running 2 Miroir replicas requires Redis. A future enhancement is a lightweight Raft-based in-process consensus so Redis is not required for HA mode.\"\n\n**Status** per plan: deferred. Current solution (Redis) works; Raft would remove an external dependency.\n\n**Research work**:\n- Survey embedded Raft crates: `openraft`, `raft-rs`, `async-raft`\n- Prototype: `TaskStore` trait impl backed by Raft state machine\n- Measure: latency + throughput vs. Redis; memory footprint per plan §14.2\n- Decide: ship in v1.x or never\n\n## Why\n\nRemoving Redis as a hard dependency shrinks the operational surface (one less thing to monitor, backup, rotate secrets for). But Raft adds complexity — a bad Raft impl can eat data in ways Redis doesn't.\n\nNot blocking v0.x or v1.0 — but worth prototyping before v2.0.\n\n## Details\n\n**Decision gate**: the Raft-backed path must be measurably better than Redis on at least one metric (ops simplicity, latency, or memory) without being worse on any of the others, before shipping.\n\n**Output**: `docs/research/raft-task-store.md` with the decision + benchmark data + reasoning.

This compilation failure is itself noted in the research doc as a data point against Raft adoption.\n- **Reusable pattern:** For research verification beads, first check if the research document already exists and is comprehensive before starting new work.
