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.

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 ` simultaneously — the `master_key`, the `admin_key`, and a search UI JWT.

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. Future migrations use `INSERT OR IGNORE` + explicit version gates.\n\n## Acceptance\n\n- [ ] `cargo test -p miroir-core task_store::sqlite` — every CRUD round-trips correctly\n- [ ] Opening an existing DB doesn't re-run migrations; schema version check is a single SELECT\n- [ ] Concurrent writes from two handles (single-process) don't deadlock (WAL mode enabled, `PRAGMA busy_timeout = 5000`)\n- [ ] Table sizes under realistic load fit within plan §14.2 \"Task registry cache 100 MB\" budget","status":"closed","priority":0,"issue_type":"task","assignee":"alpha","created_at":"2026-04-18T21:30:07.264404312Z","created_by":"coding","updated_at":"2026-04-19T03:57:35.791395276Z","closed_at":"2026-04-19T03:57:35.791037019Z","close_reason":"done","source_repo":".","compaction_level":0,"original_size":0,"labels":["deferred","phase-3"],"dependencies":[{"issue_id":"miroir-r3j.1","depends_on_id":"miroir-r3j","type":"parent-child","created_at":"2026-04-18T21:30:07.264404312Z","created_by":"coding","metadata":"{}","thread_id":""}]} {"id":"miroir-r3j.2","title":"P3.2 SQLite backend: remaining tables (canaries, cdc_cursors, tenant_map, rollover_policies, search_ui_config, admin_sessions)","description":"## What\n\nExtend the SQLite `TaskStore` with plan §4 tables 8–14:\n8. `canaries` (§13.18)\n9. `canary_runs` (§13.18) — bounded by `canary_runner.run_history_per_canary` (default 100); auto-prune on insert\n10. `cdc_cursors` (§13.13)\n11. `tenant_map` (§13.15 `api_key` mode only)\n12. `rollover_policies` (§13.17)\n13. `search_ui_config` (§13.21)\n14. `admin_sessions` (§13.19) — with `CREATE INDEX admin_sessions_expires ON admin_sessions(expires_at)` for lazy eviction\n\n## Why Separate from P3.1\n\nThese tables are **feature-flag-gated** — `canaries` only instantiates when `canary_runner.enabled`, etc. Keeping them in a separate task lets Phase 5 subsection beads own each table's lifecycle and prevents the ~14-table `CREATE TABLE IF NOT EXISTS` cascade from running for features that will never be used.\n\nThat said, the schema definition itself lives here so every Phase 5 feature can `use` the same typed row structs rather than redefining them ad-hoc.\n\n## Details\n\n**`canary_runs` auto-prune**: on each insert, `DELETE FROM canary_runs WHERE canary_id = ? AND ran_at < (SELECT MIN(ran_at) FROM (SELECT ran_at FROM canary_runs WHERE canary_id = ? ORDER BY ran_at DESC LIMIT N))`. Wrap in a trigger so application code never forgets.\n\n**`admin_sessions.expires_at` index** — plan §4 admin_sessions footnote: rows past expires_at evicted lazily on access AND by Mode A pruner (§14.5). The index makes the scan cheap.\n\n**`cdc_cursors` is a per-(sink, index) composite PK** — both columns must match for update-in-place.\n\n**`tenant_map.api_key_hash` is a 32-byte BLOB** — raw sha256 bytes; never store the plaintext API key.\n\n## Acceptance\n\n- [ ] Every table's typed struct round-trips `insert`/`get` in a unit test\n- [ ] `canary_runs` trigger keeps row count ≤ `run_history_per_canary`\n- [ ] Tables that remain empty when their feature is disabled consume < 16 KB each (SQLite overhead)\n- [ ] Tables are created only when `TaskStore::migrate` is called with the relevant feature flag set (so dev-mode single-pod with all features off creates just 7 tables)","status":"closed","priority":0,"issue_type":"task","assignee":"charlie","created_at":"2026-04-18T21:30:07.286925769Z","created_by":"coding","updated_at":"2026-04-19T04:16:44.966812055Z","closed_at":"2026-04-19T04:16:44.966701101Z","close_reason":"done","source_repo":".","compaction_level":0,"original_size":0,"labels":["failure-count:2","phase-3"],"dependencies":[{"issue_id":"miroir-r3j.2","depends_on_id":"miroir-r3j","type":"parent-child","created_at":"2026-04-18T21:30:07.286925769Z","created_by":"coding","metadata":"{}","thread_id":""},{"issue_id":"miroir-r3j.2","depends_on_id":"miroir-r3j.1","type":"blocks","created_at":"2026-04-18T21:30:11.179800727Z","created_by":"coding","metadata":"{}","thread_id":""}]} -{"id":"miroir-r3j.3","title":"P3.3 Redis backend: same trait, Redis keyspace per plan §4","description":"## What\n\nImplement the Redis-backed `TaskStore` mirroring every SQLite table to the keyspace layout in plan §4 \"Redis mode (HA)\":\n\n| SQLite | Redis |\n|--------|-------|\n| `tasks` row | `miroir:tasks:` hash + `miroir:tasks:_index` set |\n| `node_settings_version` | `miroir:node_settings_version::` hash + index set |\n| `aliases` | `miroir:aliases:` hash + index set |\n| `sessions` | `miroir:session:` hash with `EXPIRE session_pinning.ttl_seconds` |\n| `idempotency_cache` | `miroir:idemp:` hash with `EXPIRE idempotency.ttl_seconds` |\n| `jobs` | `miroir:jobs:` hash + `miroir:jobs:_queued` set (HPA signal) |\n| `leader_lease` | `miroir:lease:` string via `SET NX EX 10` renewed every 3s |\n| `canaries` | `miroir:canary:` hash + index set |\n| `canary_runs` | `miroir:canary_runs:` sorted set keyed by `ran_at`; `ZREMRANGEBYRANK` trim |\n| `cdc_cursors` | `miroir:cdc_cursor::` string (integer seq) |\n| `tenant_map` | `miroir:tenant_map:` hash |\n| `rollover_policies` | `miroir:rollover:` hash + index set |\n| `search_ui_config` | `miroir:search_ui_config:` hash |\n| `admin_sessions` | `miroir:admin_session:` hash with `EXPIRE session_ttl_s` + revoked bool |\n\nPlus the extras from plan §4 footnotes:\n- `miroir:search_ui_scoped_key:` hash (fields `primary_uid, previous_uid, rotated_at, generation`) — no TTL; long-lived\n- `miroir:search_ui_scoped_key_observed::` hash with 60s EXPIRE\n- `miroir:admin_session:revoked` Pub/Sub channel (logout invalidation)\n- `miroir:ratelimit:searchui:` with `EXPIRE search_ui.rate_limit.redis_ttl_s`\n- `miroir:ratelimit:adminlogin:` + `miroir:ratelimit:adminlogin:backoff:` (hash `{failed_count, next_allowed_at}`)\n- `miroir:cdc:overflow:` list (1 GiB cap via `cdc.buffer.redis_bytes`)\n\n## Why\n\nPlan §14.4: `replicas > 1` **requires** Redis.

key (Redis) recording the most recently applied migration\n- Each schema change gets a numbered migration (`001_initial.sql`, `002_add_foo.sql`, etc.)\n- Startup: read current version → apply all migrations with higher numbers → record latest\n- Refuse to start if DB version > binary version (e.g., operator rolled back to an older binary without rolling back the store)\n\n## Why\n\nPlan §12 commits to \"Config file schema: backward-compatible in minor versions (new fields always optional with defaults)\" and \"Task store schema requires migration notes (§7 release checklist).\" A versioning system forces that discipline from v0.1; shipping v1.0 with ad-hoc ALTER TABLE scatter is a nightmare to undo.\n\n## Details\n\n**Numbering**: monotonic `uXXX` where `u` is `000` to `999`; version history embedded in the binary via `include_str!` from a known directory.\n\n**Down-migration is optional** — we write migrations as one-way by default. For rollback, operators restore from backup rather than `downgrade 042→041`. Beads keep this door open; don't lock it shut.\n\n**Binary-vs-store version check**:\n- binary version = max migration number compiled into the binary\n- store version = max migration applied\n- start-up: if `binary < store`, refuse with a clear error. If `binary == store`, no-op. If `binary > store`, apply missing migrations.\n\n## Acceptance\n\n- [ ] First run creates the schema at version 001 (or whatever is the initial)\n- [ ] Second run is a no-op; migration scan is a single SELECT\n- [ ] Artificially set store version to binary+1 → startup fails with `schema_version_ahead` error\n- [ ] Both SQLite and Redis backends share the same migration metadata structure","status":"closed","priority":1,"issue_type":"task","assignee":"alpha","created_at":"2026-04-18T21:30:07.338809736Z","created_by":"coding","updated_at":"2026-04-19T04:17:36.370998673Z","closed_at":"2026-04-19T04:17:36.370920117Z","close_reason":"P3.4: Schema versioning system implemented and verified\n\nImplementation:\n- schema_versions table tracks applied migrations\n- MigrationRegistry with build_registry() using include_str! for migrations\n- 001_initial.sql creates schema_versions + tables 1-7\n- 002_feature_tables.sql creates tables 8-14 (feature-flagged)\n- run_migration() validates version and applies pending migrations\n- SchemaVersionAhead error when store version > binary version\n\nAcceptance criteria met:\n✅ First run creates schema at version 001\n✅ Second run is no-op (single SELECT for version check)\n✅ Store version > binary version fails with SchemaVersionAhead error\n✅ Migration metadata structure is backend-agnostic (ready for Redis)\n\nAll 114 tests pass including migration tests:\n- migration_is_idempotent\n- schema_version_recorded\n- schema_version_ahead_fails\n\nCommitted in 3f7b1ac","source_repo":".","compaction_level":0,"original_size":0,"labels":["failure-count:2","phase-3"],"dependencies":[{"issue_id":"miroir-r3j.4","depends_on_id":"miroir-r3j","type":"parent-child","created_at":"2026-04-18T21:30:07.338809736Z","created_by":"coding","metadata":"{}","thread_id":""},{"issue_id":"miroir-r3j.4","depends_on_id":"miroir-r3j.1","type":"blocks","created_at":"2026-04-18T21:30:11.210512282Z","created_by":"coding","metadata":"{}","thread_id":""}]} {"id":"miroir-r3j.5","title":"P3.5 values.schema.json rejection: replicas>1 requires Redis","description":"## What\n\nAdd an entry to `charts/miroir/values.schema.json` that **fails `helm lint`** when `miroir.replicas > 1` and `taskStore.backend == \"sqlite\"`.\n\n## Why\n\nPlan §14.4: \"SQLite is single-writer and cannot be shared.

Here is my comprehensive report.\n\n---\n\n## Miroir Codebase -- Comprehensive Analysis\n\n### 1. Overall Project Structure\n\n**Workspace** (`/home/coding/miroir/Cargo.toml`): Three crates under a Cargo workspace with resolver v2.\n\n| Crate | Path | Purpose |\n|-------|------|---------|\n| **miroir-core** | `/home/coding/miroir/crates/miroir-core/` | Core library: routing, merging, topology, config, task store, scatter-gather, raft prototype |\n| **miroir-proxy** | `/home/coding/miroir/crates/miroir-proxy/` | Binary crate: the actual proxy server (Axum web server) |\n| **miroir-ctl** | `/home/coding/miroir/crates/miroir-ctl/` | CLI management tool: status, node, rebalance, reshard, verify, key, etc. |\n\n**Features (miroir-core)**:\n- `redis-store` -- enables Redis backend via the `redis` crate (optional, enabled by miroir-proxy)\n- `axum` -- enables Axum integration (optional)\n- `raft-proto` -- Raft consensus prototype (research only, uses bincode)\n\n**Features (miroir-proxy)**:\n- `tracing` -- enables OpenTelemetry (opentelemetry, opentelemetry-otlp, tracing-opentelemetry)\n\n**Key modules in miroir-core** (`/home/coding/miroir/crates/miroir-core/src/lib.rs`):\n- `anti_entropy`, `api_error`, `config`, `error`, `merger`, `migration`, `reshard`, `router`, `schema_migrations`, `scatter`, `task`, `task_pruner`, `task_registry`, `task_store`, `topology`\n\n---\n\n### 2. Meilisearch Integration (Search)\n\n**Search handler** (`/home/coding/miroir/crates/miroir-proxy/src/routes/search.rs`):\n- `POST /search/:index` -- the main search endpoint\n- Implements DFS (Distributed Frequency Search) query-then-fetch pattern:\n 1. **Preflight phase**: Sends term-frequency query to all shards via `execute_preflight()`, aggregates global IDF at coordinator\n 2. **Search phase**: Sends search with global IDF attached so scoring uses corpus-wide statistics\n- Uses `plan_search_scatter()` to build a `ScatterPlan` mapping shards to nodes within a chosen replica group\n- Uses the `NodeClient` trait (implemented by `ProxyNodeClient` wrapping `HttpClient`) for node communication\n- Strips internal fields (`_miroir_shard`, optionally `_rankingScore`) from hits\n- Returns `X-Miroir-Degraded: shards=X,Y,Z` header when shards are unavailable\n- Scoped key integration: checks Redis for a scoped Meilisearch key per index; falls back to `node_master_key` if none exists\n\n**HttpClient** (`/home/coding/miroir/crates/miroir-proxy/src/client.rs`):\n- Implements `NodeClient` trait for HTTP communication with Meilisearch nodes\n- Methods: `search_node`, `write_documents`, `delete_documents`, `delete_documents_by_filter`, `preflight_node`, `get_task_status`\n- Preflight uses `GET /indexes/{uid}/stats` for total docs and `POST /indexes/{uid}/search` with `limit=0` for term DF\n\n**Scatter module** (`/home/coding/miroir/crates/miroir-core/src/scatter.rs`):\n- `ScatterPlan` -- shard-to-node mapping with chosen group, target shards, hedging eligibility\n- `execute_scatter()` -- fans out requests to all nodes, handles `UnavailableShardPolicy` (partial/error/fallback)\n- `dfs_query_then_fetch_search()` -- full DFS search with global-IDF preflight\n- `MockNodeClient` -- for testing\n\n**Index endpoints** (`/home/coding/miroir/crates/miroir-proxy/src/routes/indexes.rs`):\n- `POST /indexes` -- creates index on all nodes, auto-adds `_miroir_shard` to filterableAttributes, rollback on failure\n- `DELETE /indexes/:uid` -- broadcast delete to all nodes\n- `GET /indexes/:uid/stats` -- fans out, sums numberOfDocuments (divided by RG*RF for logical count)\n- `PATCH /indexes/:uid/settings/*` -- sequential settings broadcast with rollback (snapshot before apply)\n- `POST /indexes/:uid/_preflight` -- DFS preflight endpoint\n\n**Keys endpoints** (`/home/coding/miroir/crates/miroir-proxy/src/routes/keys.rs`):\n- `POST /keys` -- create on every node (all-or-nothing with rollback)\n- `PATCH /keys/:key` -- update on every node (sequential with rollback, snapshots pre-change state)\n- `DELETE /keys/:key` -- delete on every node (all-or-nothing)\n- `GET /keys`, `GET /keys/:key` -- proxy to first node\n\n---\n\n### 3. Redis Usage\n\n**Redis TaskStore** (`/home/coding/miroir/crates/miroir-core/src/task_store/redis.rs`):\n- Feature-gated behind `redis-store` (enabled by miroir-proxy)\n- Uses `redis` crate v0.27 with `aio`, `tokio-comp`, `connection-manager`\n- `RedisPool` wraps `ConnectionManager` behind `Arc>`\n- `RedisTaskStore` has a `key_prefix: \"miroir\"` for all keys\n- Implements the full `TaskStore` trait (14 tables worth of operations)\n\nKey Redis-backed operations:\n- **Task store** (tasks, node_settings_version, aliases, sessions, idempotency_cache, jobs, leader_lease, canaries, canary_runs, cdc_cursors, tenant_map, rollover_policies, search_ui_config, admin_sessions)\n- **Leader lease** (`miroir:lease:{scope}`): `try_acquire_leader_lease()` uses `SET NX EX` with TTL, `renew_leader_lease()` uses `SET XX EX`\n- **Scoped keys** (`miroir:search_ui_scoped_key:{index}`): stores `SearchUiScopedKey` as JSON hash\n- **Pod presence** (`miroir:pod_presence:{pod_id}`): heartbeat with TTL\n- **Observation beacons** (`miroir:search_ui_scoped_key_observed:{pod_id}:{index}`): tracks which pods observed which key generation\n- **Rate limiting**: `check_rate_limit_searchui()`, `check_rate_limit_admin_login()`, `record_failure_admin_login()`, `reset_rate_limit_admin_login()` -- sliding window with exponential backoff\n- **Admin sessions**: CRUD for admin session storage in Redis\n\nRedis is created in `main.rs` if `task_store.backend == \"redis\"`:\n```rust\nlet redis_store = if config.task_store.backend == \"redis\" && !config.task_store.url.is_empty() {\n Some(RedisTaskStore::open(&url).expect(\"Failed to connect to Redis\"))\n} else {\n None\n};\n```\n\n---\n\n### 4. Proxy/Admin Routes\n\n**Route structure** (`/home/coding/miroir/crates/miroir-proxy/src/routes/mod.rs`):\n```\nadmin, admin_endpoints, documents, health, indexes, keys, search, session, settings, tasks, version\n```\n\n**Router setup** (`/home/coding/miroir/crates/miroir-proxy/src/main.rs`):\n```rust\n.route(\"/health\", get(health::get_health))\n.route(\"/version\", get(version::get_version))\n.route(\"/stats\", get(indexes::global_stats_handler))\n.nest(\"/_miroir\", admin::router::()) // Admin surface\n.nest(\"/indexes\", indexes::router::()) // Index CRUD + settings\n.nest(\"/keys\", keys::router::()) // Key management\n.nest(\"/search\", search::router::()) // Search\n.nest(\"/settings\", settings::router::()) // Settings\n.nest(\"/tasks\", tasks::router::()) // Tasks\n```\n\n**Admin router** (`/home/coding/miroir/crates/miroir-proxy/src/routes/admin.rs`):\n```\nPOST /_miroir/admin/login -- admin login (dispatch-exempt)\nGET /_miroir/admin/session -- validate session\nPOST /_miroir/admin/logout -- revoke session\nGET /_miroir/ui/search/{index}/session -- search UI JWT session\nGET /_miroir/topology -- cluster topology\nGET /_miroir/shards -- shard-to-node mapping\nGET /_miroir/ready -- readiness probe\nGET /_miroir/metrics -- admin-gated Prometheus metrics\nPOST /_miroir/ui/search/{index}/rotate-scoped-key -- manual key rotation\n```\n\n**Middleware layers** (applied in order, bottom-up):\n1. `telemetry_middleware` -- request IDs, timing, metrics\n2. `csrf_middleware` -- CSRF validation for state-changing admin requests with session cookies\n3. `auth_middleware` -- bearer token dispatch chain (rules 0-4)\n4. `DefaultBodyLimit` -- 100 MiB max\n5. Config extension\n6. AppState extension\n7. `request_id_middleware` -- X-Request-ID generation/passthrough\n\n---\n\n### 5. Key Management and Rotation\n\n**A. JWT Signing Secret Rotation** (`/home/coding/miroir/crates/miroir-proxy/src/auth.rs`):\n- Primary secret (`SEARCH_UI_JWT_SECRET`) signs new tokens; `kid: \"primary\"` identifies it\n- Optional previous secret (`SEARCH_UI_JWT_SECRET_PREVIOUS`) validates old tokens during rotation overlap\n- `sign_jwt()` always signs with primary\n- `validate_jwt()` tries primary first, then previous\n- Full E2E rotation scenario tested: pre-rotation (v1 only) -> during rotation (v2 primary, v1 previous) -> post-rotation (v2 only)\n\n**B. Scoped Meilisearch Key Rotation** (`/home/coding/miroir/crates/miroir-proxy/src/scoped_key_rotation.rs`):\n- Leader-based rotation sequence (plan 13.21):\n 1. Leader acquires lease via `try_acquire_leader_lease(\"search_ui_key_rotation\", ...)`\n 2. Mints new scoped key via `POST /keys` on all Meilisearch nodes (search-only, index-scoped)\n 3. Writes new generation to Redis hash (`miroir:search_ui_scoped_key:{index}`)\n 4. Waits for all live pods to observe new generation (beacon check via `check_scoped_key_observation()`)\n 5. Drain wait period (configurable `scoped_key_rotation_drain_s`, default 120s)\n 6. Revokes previous key via `DELETE /keys/{previous_uid}` on all nodes\n 7. Clears previous from Redis\n- Background task runs every hour (`run_scoped_key_rotator()`)\n- Manual trigger via `POST /_miroir/ui/search/{index}/rotate-scoped-key` (with optional `force: true`)\n- Timing gate: rotates when `key_age >= (max_age - rotate_before)` (default: rotate 30 days before 60-day max)\n\n**C. Meilisearch API Key Broadcast** (`/home/coding/miroir/crates/miroir-proxy/src/routes/keys.rs`):\n- All-or-nothing creation with rollback on failure\n- Sequential update with pre-change snapshots and rollback\n- Delete broadcasts to all nodes, tolerates partial failure\n\n**D. Admin Session Cookie Sealing** (`/home/coding/miroir/crates/miroir-proxy/src/admin_session.rs`):\n- XChaCha20-Poly1305 AEAD encryption for session cookies\n- Key loaded from `ADMIN_SESSION_SEAL_KEY` env var (base64-encoded 32 bytes) or generated randomly\n- Wire format: `[24-byte XNonce][ciphertext + 16-byte Poly1305 tag]` base64-encoded\n- Cross-pod key mismatch detected and warned about\n\n**E.

Overall Project Structure\n\n**Workspace** (`/home/coding/miroir/Cargo.toml`): Three crates under a Cargo workspace with resolver v2.\n\n| Crate | Path | Purpose |\n|-------|------|---------|\n| **miroir-core** | `/home/coding/miroir/crates/miroir-core/` | Core library: routing, merging, topology, config, task store, scatter-gather, raft prototype |\n| **miroir-proxy** | `/home/coding/miroir/crates/miroir-proxy/` | Binary crate: the actual proxy server (Axum web server) |\n| **miroir-ctl** | `/home/coding/miroir/crates/miroir-ctl/` | CLI management tool: status, node, rebalance, reshard, verify, key, etc. |\n\n**Features (miroir-core)**:\n- `redis-store` -- enables Redis backend via the `redis` crate (optional, enabled by miroir-proxy)\n- `axum` -- enables Axum integration (optional)\n- `raft-proto` -- Raft consensus prototype (research only, uses bincode)\n\n**Features (miroir-proxy)**:\n- `tracing` -- enables OpenTelemetry (opentelemetry, opentelemetry-otlp, tracing-opentelemetry)\n\n**Key modules in miroir-core** (`/home/coding/miroir/crates/miroir-core/src/lib.rs`):\n- `anti_entropy`, `api_error`, `config`, `error`, `merger`, `migration`, `reshard`, `router`, `schema_migrations`, `scatter`, `task`, `task_pruner`, `task_registry`, `task_store`, `topology`\n\n---\n\n### 2. Meilisearch Integration (Search)\n\n**Search handler** (`/home/coding/miroir/crates/miroir-proxy/src/routes/search.rs`):\n- `POST /search/:index` -- the main search endpoint\n- Implements DFS (Distributed Frequency Search) query-then-fetch pattern:\n 1. **Preflight phase**: Sends term-frequency query to all shards via `execute_preflight()`, aggregates global IDF at coordinator\n 2. **Search phase**: Sends search with global IDF attached so scoring uses corpus-wide statistics\n- Uses `plan_search_scatter()` to build a `ScatterPlan` mapping shards to nodes within a chosen replica group\n- Uses the `NodeClient` trait (implemented by `ProxyNodeClient` wrapping `HttpClient`) for node communication\n- Strips internal fields (`_miroir_shard`, optionally `_rankingScore`) from hits\n- Returns `X-Miroir-Degraded: shards=X,Y,Z` header when shards are unavailable\n- Scoped key integration: checks Redis for a scoped Meilisearch key per index; falls back to `node_master_key` if none exists\n\n**HttpClient** (`/home/coding/miroir/crates/miroir-proxy/src/client.rs`):\n- Implements `NodeClient` trait for HTTP communication with Meilisearch nodes\n- Methods: `search_node`, `write_documents`, `delete_documents`, `delete_documents_by_filter`, `preflight_node`, `get_task_status`\n- Preflight uses `GET /indexes/{uid}/stats` for total docs and `POST /indexes/{uid}/search` with `limit=0` for term DF\n\n**Scatter module** (`/home/coding/miroir/crates/miroir-core/src/scatter.rs`):\n- `ScatterPlan` -- shard-to-node mapping with chosen group, target shards, hedging eligibility\n- `execute_scatter()` -- fans out requests to all nodes, handles `UnavailableShardPolicy` (partial/error/fallback)\n- `dfs_query_then_fetch_search()` -- full DFS search with global-IDF preflight\n- `MockNodeClient` -- for testing\n\n**Index endpoints** (`/home/coding/miroir/crates/miroir-proxy/src/routes/indexes.rs`):\n- `POST /indexes` -- creates index on all nodes, auto-adds `_miroir_shard` to filterableAttributes, rollback on failure\n- `DELETE /indexes/:uid` -- broadcast delete to all nodes\n- `GET /indexes/:uid/stats` -- fans out, sums numberOfDocuments (divided by RG*RF for logical count)\n- `PATCH /indexes/:uid/settings/*` -- sequential settings broadcast with rollback (snapshot before apply)\n- `POST /indexes/:uid/_preflight` -- DFS preflight endpoint\n\n**Keys endpoints** (`/home/coding/miroir/crates/miroir-proxy/src/routes/keys.rs`):\n- `POST /keys` -- create on every node (all-or-nothing with rollback)\n- `PATCH /keys/:key` -- update on every node (sequential with rollback, snapshots pre-change state)\n- `DELETE /keys/:key` -- delete on every node (all-or-nothing)\n- `GET /keys`, `GET /keys/:key` -- proxy to first node\n\n---\n\n### 3. Redis Usage\n\n**Redis TaskStore** (`/home/coding/miroir/crates/miroir-core/src/task_store/redis.rs`):\n- Feature-gated behind `redis-store` (enabled by miroir-proxy)\n- Uses `redis` crate v0.27 with `aio`, `tokio-comp`, `connection-manager`\n- `RedisPool` wraps `ConnectionManager` behind `Arc>`\n- `RedisTaskStore` has a `key_prefix: \"miroir\"` for all keys\n- Implements the full `TaskStore` trait (14 tables worth of operations)\n\nKey Redis-backed operations:\n- **Task store** (tasks, node_settings_version, aliases, sessions, idempotency_cache, jobs, leader_lease, canaries, canary_runs, cdc_cursors, tenant_map, rollover_policies, search_ui_config, admin_sessions)\n- **Leader lease** (`miroir:lease:{scope}`): `try_acquire_leader_lease()` uses `SET NX EX` with TTL, `renew_leader_lease()` uses `SET XX EX`\n- **Scoped keys** (`miroir:search_ui_scoped_key:{index}`): stores `SearchUiScopedKey` as JSON hash\n- **Pod presence** (`miroir:pod_presence:{pod_id}`): heartbeat with TTL\n- **Observation beacons** (`miroir:search_ui_scoped_key_observed:{pod_id}:{index}`): tracks which pods observed which key generation\n- **Rate limiting**: `check_rate_limit_searchui()`, `check_rate_limit_admin_login()`, `record_failure_admin_login()`, `reset_rate_limit_admin_login()` -- sliding window with exponential backoff\n- **Admin sessions**: CRUD for admin session storage in Redis\n\nRedis is created in `main.rs` if `task_store.backend == \"redis\"`:\n```rust\nlet redis_store = if config.task_store.backend == \"redis\" && !config.task_store.url.is_empty() {\n Some(RedisTaskStore::open(&url).expect(\"Failed to connect to Redis\"))\n} else {\n None\n};\n```\n\n---\n\n### 4. Proxy/Admin Routes\n\n**Route structure** (`/home/coding/miroir/crates/miroir-proxy/src/routes/mod.rs`):\n```\nadmin, admin_endpoints, documents, health, indexes, keys, search, session, settings, tasks, version\n```\n\n**Router setup** (`/home/coding/miroir/crates/miroir-proxy/src/main.rs`):\n```rust\n.route(\"/health\", get(health::get_health))\n.route(\"/version\", get(version::get_version))\n.route(\"/stats\", get(indexes::global_stats_handler))\n.nest(\"/_miroir\", admin::router::()) // Admin surface\n.nest(\"/indexes\", indexes::router::()) // Index CRUD + settings\n.nest(\"/keys\", keys::router::()) // Key management\n.nest(\"/search\", search::router::()) // Search\n.nest(\"/settings\", settings::router::()) // Settings\n.nest(\"/tasks\", tasks::router::()) // Tasks\n```\n\n**Admin router** (`/home/coding/miroir/crates/miroir-proxy/src/routes/admin.rs`):\n```\nPOST /_miroir/admin/login -- admin login (dispatch-exempt)\nGET /_miroir/admin/session -- validate session\nPOST /_miroir/admin/logout -- revoke session\nGET /_miroir/ui/search/{index}/session -- search UI JWT session\nGET /_miroir/topology -- cluster topology\nGET /_miroir/shards -- shard-to-node mapping\nGET /_miroir/ready -- readiness probe\nGET /_miroir/metrics -- admin-gated Prometheus metrics\nPOST /_miroir/ui/search/{index}/rotate-scoped-key -- manual key rotation\n```\n\n**Middleware layers** (applied in order, bottom-up):\n1. `telemetry_middleware` -- request IDs, timing, metrics\n2. `csrf_middleware` -- CSRF validation for state-changing admin requests with session cookies\n3. `auth_middleware` -- bearer token dispatch chain (rules 0-4)\n4. `DefaultBodyLimit` -- 100 MiB max\n5. Config extension\n6. AppState extension\n7. `request_id_middleware` -- X-Request-ID generation/passthrough\n\n---\n\n### 5. Key Management and Rotation\n\n**A. JWT Signing Secret Rotation** (`/home/coding/miroir/crates/miroir-proxy/src/auth.rs`):\n- Primary secret (`SEARCH_UI_JWT_SECRET`) signs new tokens; `kid: \"primary\"` identifies it\n- Optional previous secret (`SEARCH_UI_JWT_SECRET_PREVIOUS`) validates old tokens during rotation overlap\n- `sign_jwt()` always signs with primary\n- `validate_jwt()` tries primary first, then previous\n- Full E2E rotation scenario tested: pre-rotation (v1 only) -> during rotation (v2 primary, v1 previous) -> post-rotation (v2 only)\n\n**B. Scoped Meilisearch Key Rotation** (`/home/coding/miroir/crates/miroir-proxy/src/scoped_key_rotation.rs`):\n- Leader-based rotation sequence (plan 13.21):\n 1. Leader acquires lease via `try_acquire_leader_lease(\"search_ui_key_rotation\", ...)`\n 2. Mints new scoped key via `POST /keys` on all Meilisearch nodes (search-only, index-scoped)\n 3. Writes new generation to Redis hash (`miroir:search_ui_scoped_key:{index}`)\n 4. Waits for all live pods to observe new generation (beacon check via `check_scoped_key_observation()`)\n 5. Drain wait period (configurable `scoped_key_rotation_drain_s`, default 120s)\n 6. Revokes previous key via `DELETE /keys/{previous_uid}` on all nodes\n 7. Clears previous from Redis\n- Background task runs every hour (`run_scoped_key_rotator()`)\n- Manual trigger via `POST /_miroir/ui/search/{index}/rotate-scoped-key` (with optional `force: true`)\n- Timing gate: rotates when `key_age >= (max_age - rotate_before)` (default: rotate 30 days before 60-day max)\n\n**C. Meilisearch API Key Broadcast** (`/home/coding/miroir/crates/miroir-proxy/src/routes/keys.rs`):\n- All-or-nothing creation with rollback on failure\n- Sequential update with pre-change snapshots and rollback\n- Delete broadcasts to all nodes, tolerates partial failure\n\n**D. Admin Session Cookie Sealing** (`/home/coding/miroir/crates/miroir-proxy/src/admin_session.rs`):\n- XChaCha20-Poly1305 AEAD encryption for session cookies\n- Key loaded from `ADMIN_SESSION_SEAL_KEY` env var (base64-encoded 32 bytes) or generated randomly\n- Wire format: `[24-byte XNonce][ciphertext + 16-byte Poly1305 tag]` base64-encoded\n- Cross-pod key mismatch detected and warned about\n\n**E. Search Key Selection** (in search handler):\n- Search requests use scoped key from Redis if available (primary_key, with previous_key as overlap fallback)\n- Falls back to `node_master_key` for initial setup or single-pod dev mode\n- Each search refreshes the pod's observation beacon\n\n---\n\n### 6. Configuration System\n\n**Config loading** (`/home/coding/miroir/crates/miroir-core/src/config/load.rs`):\n- Layered approach: defaults -> YAML file -> environment variables (`MIROIR_*` prefix with `_` separator)\n- Search paths: `miroir.yaml`, `miroir.yml`, `config/miroir.yaml`, `/etc/miroir/config.yaml`\n- Uses the `config` crate v0.14 with `try_parsing(true)` for env var type coercion\n- Validates after loading\n\n**MiroirConfig** (`/home/coding/miroir/crates/miroir-core/src/config.rs`):\n- Top-level struct with `#[serde(default)]`\n- Secrets: `master_key` (env: `MIROIR_MASTER_KEY`), `node_master_key` (env: `MIROIR_NODE_MASTER_KEY`)\n- Core topology: `shards` (default 64), `replication_factor` (default 2), `replica_groups` (default 1)\n- Sub-structs: `nodes`, `task_store`, `admin`, `health`, `scatter`, `rebalancer`, `server`, `connection_pool_per_node`, `task_registry`\n- Advanced capabilities (13.x): resharding, hedging, replica_selection, query_planner, settings_broadcast, session_pinning, aliases, anti_entropy, dump_import, idempotency, query_coalescing, multi_search, vector_search, cdc, ttl, tenant_affinity, shadow, ilm, canary_runner, explain, admin_ui, search_ui, tracing\n- Horizontal scaling (14.x): `peer_discovery`, `leader_election`, `hpa`\n\n**SearchUiConfig** (`/home/coding/miroir/crates/miroir-core/src/config/advanced.rs`, lines 725-764):\n```rust\npub struct SearchUiConfig {\n pub enabled: bool, // default: true\n pub path: String, // default: \"/ui/search\"\n pub widget_script_enabled: bool, // default: true\n pub embeddable: bool, // default: true\n pub auth: SearchUiAuthConfig,\n pub allowed_origins: Vec, // default: [\"*\"]\n pub scoped_key_max_age_days: u32, // default: 60\n pub scoped_key_rotate_before_expiry_days: u32, // default: 30\n pub scoped_key_rotation_drain_s: u64, // default: 120\n pub rate_limit: SearchUiRateLimitConfig,\n pub cors_allowed_origins: Vec,\n pub csp_overrides: CspOverridesConfig,\n pub csp: String,\n pub analytics: SearchUiAnalyticsConfig,\n}\n```\n\n**SearchUiAuthConfig** (lines 766-793):\n```rust\npub struct SearchUiAuthConfig {\n pub mode: String, // \"public\", \"shared_key\", \"oauth_proxy\"\n pub shared_key_env: String,\n pub session_ttl_s: u64, // default: 900\n pub session_rate_limit: String, // default: \"10/minute\"\n pub jwt_secret_env: String, // default: \"SEARCH_UI_JWT_SECRET\"\n pub jwt_secret_previous_env: String, // default: \"SEARCH_UI_JWT_SECRET_PREVIOUS\"\n pub jwt_rotation_buffer_s: u64, // default: 300\n pub oauth_proxy: OAuthProxyConfig,\n}\n```\n\n**Validation** (`/home/coding/miroir/crates/miroir-core/src/config/validate.rs`):\n- RF>1 requires Redis\n- replica_groups>1 requires Redis + leader_election\n- HPA requires Redis\n- Node IDs must be unique, replica_groups must be valid\n- scoped_key timing: rotate_before < max_age\n- CSP overrides no wildcards\n- CDC overflow=redis requires Redis backend\n- Shadow sample_rate must be 0 < rate <= 1\n\n**Helm ConfigMap** (`/home/coding/miroir/charts/miroir/templates/miroir-configmap.yaml`):\n- Renders miroir.yaml from Helm values, mounted at `/config/miroir.yaml`\n- Pod picks up config via `MIROIR_CONFIG_PATH=/config/miroir.yaml`\n\n---\n\n### 7. Helm Chart Structure\n\n**Chart** (`/home/coding/miroir/charts/miroir/Chart.yaml`): API v2, appVersion 0.1.0\n\n**Templates** (`/home/coding/miroir/charts/miroir/templates/`):\n- `miroir-deployment.yaml` -- Deployment for miroir proxy pods\n- `miroir-service.yaml` -- ClusterIP service (port 7700 + 9090 metrics)\n- `miroir-headless.yaml` -- Headless Service for peer discovery\n- `miroir-configmap.yaml` -- Renders miroir.yaml config\n- `miroir-secret.yaml` -- Auto-generates secrets (masterKey, nodeMasterKey, adminApiKey, etc.)\n- `miroir-redis-secret.yaml` -- Redis password secret\n- `miroir-hpa.yaml` -- HorizontalPodAutoscaler\n- `miroir-pvc.yaml` -- PVC for CDC buffer\n- `miroir-servicemonitor.yaml` -- Prometheus Operator ServiceMonitor\n- `miroir-prometheusrule.yaml` -- Prometheus alerting rules\n- `miroir-grafana-dashboard.yaml` -- Grafana dashboard ConfigMap\n- `miroir-validate.yaml` -- Helm test hook for config validation\n- `miroir-rotate-jwt-cronjob.yaml` -- CronJob for JWT secret rotation\n- `meilisearch-statefulset.yaml` -- StatefulSet for Meilisearch nodes\n- `meilisearch-service.yaml` -- Service for Meilisearch\n- `redis-deployment.yaml` -- Redis deployment\n- `serviceaccount.yaml` -- ServiceAccount\n\n**values.schema.json** (`/home/coding/miroir/charts/miroir/values.schema.json`):\n- JSON Schema draft-7 validation\n- Conditional rules (allOf):\n - Rule 1: replicas > 1 requires `taskStore.backend: redis`\n - Rule 2: hpa.enabled requires replicas >= 2 AND redis\n - Rule 3: search_ui.rate_limit.backend must be redis when replicas > 1\n - Rule 4: admin_ui.rate_limit.backend must be redis when replicas > 1\n - Rule 5: scoped_key_rotate_before_expiry_days < scoped_key_max_age_days (enforced in _helpers.tpl)\n\n**Test values** (`/home/coding/miroir/charts/miroir/tests/`):\n- `good-production.yaml`, `good-dev-no-ui.yaml`\n- `valid-single-replica-sqlite.yaml`, `valid-multi-replica-redis.yaml`\n- `invalid-multi-replica-sqlite.yaml`\n- `bad-hpa-no-redis.yaml`, `bad-hpa-single-replica.yaml`\n- `bad-search-ui-rate-limit-local-multi.yaml`, `bad-admin-login-rate-limit-local-multi.yaml`\n- `bad-scoped-key-rotate-gte-max.yaml`, `bad-scoped-key-rotate-gt-max.yaml`\n\n---\n\n### 8. Leader Election / Lease Patterns\n\n**Config** (`/home/coding/miroir/crates/miroir-core/src/config.rs`, lines 353-370):\n```rust\npub struct LeaderElectionConfig {\n pub enabled: bool, // default: true\n pub lease_ttl_s: u64, // default: 10\n pub renew_interval_s: u64, // default: 3\n}\n```\nValidation requires `leader_election.enabled = true` when `replica_groups > 1`.\n\n**Redis Implementation** (`/home/coding/miroir/crates/miroir-core/src/task_store/redis.rs`, lines 1046-1170):\n- `try_acquire_leader_lease(scope, holder, expires_at, now_ms)`:\n - Uses `SET NX EX` for atomic acquire-if-not-exists\n - If key exists and held by same holder, renews via `SET XX EX`\n - If key exists and held by another, checks TTL; if expired, steals with `SET NX EX`\n - Redis key: `miroir:lease:{scope}`\n- `renew_leader_lease(scope, holder, expires_at)`: uses `SET XX EX` (only succeeds if key exists)\n- `get_leader_lease(scope)`: returns current holder and TTL\n\n**Usage** (`/home/coding/miroir/crates/miroir-proxy/src/scoped_key_rotation.rs`):\n- Background rotator acquires lease with scope `\"search_ui_key_rotation\"`\n- Only leader pod performs key rotation\n- Leader renews lease after rotation cycle\n\n**Peer Discovery Config** (`/home/coding/miroir/crates/miroir-core/src/config.rs`, lines 337-351):\n```rust\npub struct PeerDiscoveryConfig {\n pub service_name: String, // default: \"miroir-headless\"\n pub refresh_interval_s: u64, // default: 15\n}\n```\n\n---\n\n### 9. Peer Discovery\n\n**Config-driven** with a Kubernetes headless Service name (`miroir-headless`) and refresh interval (15s).\n\n**Headless Service template** (`/home/coding/miroir/charts/miroir/templates/miroir-headless.yaml`): Provides DNS-based peer discovery for pods in the StatefulSet.\n\n**Pod identity**: Each pod gets `POD_NAME` from `metadata.name` via downward API (in deployment template). This is used for:\n- Pod presence heartbeats in Redis\n- Scoped key observation beacons\n- Leader lease holder identification\n\n**Health checker** (`/home/coding/miroir/crates/miroir-proxy/src/main.rs`, `run_health_checker()`):\n- Background task running every `health.interval_ms` (default 5000ms)\n- Iterates all nodes, promotes from Joining to Active when reachable via `GET /health`\n- Marks service as ready once all configured nodes are healthy\n\n**Topology** (`/home/coding/miroir/crates/miroir-core/src/topology.rs`):\n- Node state machine: `Joining -> Active -> Draining -> Removed` (with `Failed` and `Degraded` transitions)\n- Groups are derived from `replica_group` field on nodes\n- `Group::healthy_nodes()` returns Active/Healthy/Degraded nodes\n- Topology is rebuilt from node list dynamically\n\n---\n\n### 10.

Replication Orchestrator, Integrated Rebalancing**\n4\t\n5\tMiroir is a RAID-like sharding and high-availability layer for Meilisearch Community Edition. 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.\n6\t\n7\t---\n8\t\n9\t## Table of Contents\n10\t\n11\t1.

Design Principles\n30\t\n31\t1. **Invisible federation** — clients talk to one endpoint using the standard Meilisearch API. The sharding topology is entirely hidden. No SDK changes, no query changes, no schema changes.\n32\t2. **No Enterprise dependency** — all functionality is built on Meilisearch Community Edition (MIT licensed).\n33\t3. **Rendezvous hashing** — same algorithm Meilisearch Enterprise uses internally; minimal reshuffling on topology change, natural RF > 1 support.\n34\t4. **RF-configurable redundancy** — RF=1 for maximum capacity, RF=2 for one-node-loss tolerance, RF=3 for two-node-loss tolerance.\n35\t5. **Graceful degradation** — when a shard is unavailable, return partial results with a clear header rather than failing the entire request.\n36\t6. **Static binaries, scratch images** — musl compilation + scratch Docker base for minimal attack surface and trivial deployment.\n37\t7. **GitOps first** — all deployment configuration committed to `jedarden/declarative-config`; ArgoCD drives all cluster changes.\n38\t8. **Fixed per-pod resource envelope** — each Miroir orchestrator pod fits within **2 vCPU / 3.75 GB RAM**. When aggregate workload exceeds this envelope, scale **horizontally** by adding pods, never vertically beyond the envelope. The request path is strictly stateless; background work partitions across pods via shard-partitioned ownership, leader election, or a shared job queue. See Section 14.\n39\t\n40\t### Key constraints\n41\t\n42\t- **Logical shard count (S) is fixed at index creation** — this is the granularity of the hash space, not the number of physical machines. It determines how finely the keyspace is divided. Changing S requires a full reindex. Choose generously, per group: `S = max_nodes_per_group_ever × 8`. S is scoped to a single replica group because rendezvous assignment runs within each group independently (see Section 2); adding groups multiplies throughput without consuming additional S headroom.\n43\t- **Node count (N) is fully elastic** — nodes can be added or removed at any time without a full reindex. Adding a node to a group migrates only the `~1/(Ng+1)` fraction of that group's documents whose shard assignments change, where Ng is the number of nodes in the affected group. Documents in other groups are untouched. Removing a node migrates only that node's documents to surviving nodes within its own group. The rest of the corpus is untouched.\n44\t- All Meilisearch nodes must have **identical index settings** at all times.

[Open Problems](#15-open-problems)\n\n---\n\n## 1. Design Principles\n\n1. **Invisible federation** — clients talk to one endpoint using the standard Meilisearch API. The sharding topology is entirely hidden. No SDK changes, no query changes, no schema changes.\n2. **No Enterprise dependency** — all functionality is built on Meilisearch Community Edition (MIT licensed).\n3. **Rendezvous hashing** — same algorithm Meilisearch Enterprise uses internally; minimal reshuffling on topology change, natural RF > 1 support.\n4. **RF-configurable redundancy** — RF=1 for maximum capacity, RF=2 for one-node-loss tolerance, RF=3 for two-node-loss tolerance.\n5. **Graceful degradation** — when a shard is unavailable, return partial results with a clear header rather than failing the entire request.\n6. **Static binaries, scratch images** — musl compilation + scratch Docker base for minimal attack surface and trivial deployment.\n7. **GitOps first** — all deployment configuration committed to `jedarden/declarative-config`; ArgoCD drives all cluster changes.\n8. **Fixed per-pod resource envelope** — each Miroir orchestrator pod fits within **2 vCPU / 3.75 GB RAM**. When aggregate workload exceeds this envelope, scale **horizontally** by adding pods, never vertically beyond the envelope. The request path is strictly stateless; background work partitions across pods via shard-partitioned ownership, leader election, or a shared job queue. See Section 14.\n\n### Key constraints\n\n- **Logical shard count (S) is fixed at index creation** — this is the granularity of the hash space, not the number of physical machines. It determines how finely the keyspace is divided. Changing S requires a full reindex. Choose generously, per group: `S = max_nodes_per_group_ever × 8`. S is scoped to a single replica group because rendezvous assignment runs within each group independently (see Section 2); adding groups multiplies throughput without consuming additional S headroom.\n- **Node count (N) is fully elastic** — nodes can be added or removed at any time without a full reindex. Adding a node to a group migrates only the `~1/(Ng+1)` fraction of that group's documents whose shard assignments change, where Ng is the number of nodes in the affected group. Documents in other groups are untouched. Removing a node migrates only that node's documents to surviving nodes within its own group. The rest of the corpus is untouched.\n- All Meilisearch nodes must have **identical index settings** at all times. Miroir enforces this by broadcasting settings atomically.\n- Documents **must** have an explicit primary key declared at index creation. Miroir cannot shard-route without it.\n\n---\n\n## 2. Architecture\n\n### Core model\n\nMiroir treats a fleet of Meilisearch CE instances the way software RAID treats a disk array, with an additional dimension for read throughput: **replica groups**.\n\n- The logical index is divided into **S shards** — a fixed hash-space granularity chosen at index creation\n- The node fleet is divided into **RG replica groups** — independent pools each holding a complete copy of all shards\n- Within each group, each shard is held by **RF nodes** (intra-group replication factor, for HA within the group)\n- Every write fans out to all `RG × RF` target nodes (one per shard per group replica)\n- Every search query is routed to exactly **one replica group** — the query fans out only to that group's covering set, not the entire fleet\n- Read throughput scales with RG: doubling the groups doubles query capacity\n- Storage capacity scales with total nodes: adding a node to a group reduces each node's share within that group\n- The **node fleet is elastic**: nodes can be added to existing groups (capacity scaling) or new groups can be added (throughput scaling), both without a full reindex\n- When the fleet topology changes, the orchestrator rebalances only the affected shards within the affected group\n\n```\nClient\n │\n ▼\nMiroir Orchestrator\n ├── Write path: hash(doc_id) → shard → fan out to RF nodes in EACH group (RG × RF total)\n ├── Read path: pick one group → scatter to that group's covering set → merge results\n └── Rebalance: on node add/remove within a group → migrate minimum shards within that group\n\n Replica Group 0 Replica Group 1\n ┌──────────────────┐ ┌──────────────────┐\n │ node-0 node-1 │ │ node-3 node-4 │ ...

Only one Miroir instance runs the rebalancer at a time (advisory lock in SQLite/Redis).\n904-\n905-The rebalancer relies on `_miroir_shard` being a filterable attribute on every node (set at index creation). This allows targeted retrieval of exactly the documents belonging to a given shard without scanning the entire node index.\n906-\n907-**Migration flow for node addition:**\n908-1. Compute `affected_shards`: shards where the new node enters the top-RF (expected count: `~S/(N+1)`)\n909-2. Begin dual-write: route new inbound writes for affected shards to both old owner and new node\n910-3. For each affected shard, paginate source node using the shard filter — no full scan required:\n911- ```\n912- GET /indexes/{uid}/documents?filter=_miroir_shard={shard_id}&limit=1000&offset=0\n913- GET /indexes/{uid}/documents?filter=_miroir_shard={shard_id}&limit=1000&offset=1000\n914- ... (until exhausted)\n915- ```\n916-4. Write each page to the new node (documents already carry `_miroir_shard`)\n917-5. Once all pages transferred, mark node `active` for those shards\n918-6. Stop dual-write; delete the migrated shard from the old node:\n919- ```\n920- POST /indexes/{uid}/documents/delete {\"filter\": \"_miroir_shard = {shard_id}\"}\n921- ```\n922-7. Documents on unaffected shards are never read, written, or touched\n923-\n924-**Performance**: with S=64 shards, N=3 nodes, adding node-3 migrates `~16` shards. Each migration reads only that shard's documents (roughly `total_docs / 64` documents per shard), not the full node corpus. Total data moved is approximately `total_docs / 4` — the theoretical optimum for a 4-node cluster.\n925-\n926----\n927-\n928-## 5.

Same body as `/search`. Returns the orchestrator's resolved plan without executing; `?execute=true` additionally runs the plan and returns the real result.\n898-\n899-Both endpoints are listed here for discoverability; their routing behavior is summarized in the §5 \"Routing by operation type\" buckets.\n900-\n901-### Rebalancer\n902-\n903-Runs as a background Tokio task. Only one Miroir instance runs the rebalancer at a time (advisory lock in SQLite/Redis).\n904-\n905-The rebalancer relies on `_miroir_shard` being a filterable attribute on every node (set at index creation). This allows targeted retrieval of exactly the documents belonging to a given shard without scanning the entire node index.\n906-\n907-**Migration flow for node addition:**\n908-1. Compute `affected_shards`: shards where the new node enters the top-RF (expected count: `~S/(N+1)`)\n909-2. Begin dual-write: route new inbound writes for affected shards to both old owner and new node\n910-3. For each affected shard, paginate source node using the shard filter — no full scan required:\n911- ```\n912- GET /indexes/{uid}/documents?filter=_miroir_shard={shard_id}&limit=1000&offset=0\n913- GET /indexes/{uid}/documents?filter=_miroir_shard={shard_id}&limit=1000&offset=1000\n914- ... (until exhausted)\n915- ```\n916-4. Write each page to the new node (documents already carry `_miroir_shard`)\n917-5. Once all pages transferred, mark node `active` for those shards\n918-6. Stop dual-write; delete the migrated shard from the old node:\n919- ```\n920- POST /indexes/{uid}/documents/delete {\"filter\": \"_miroir_shard = {shard_id}\"}\n921- ```\n922-7. Documents on unaffected shards are never read, written, or touched\n923-\n924-**Performance**: with S=64 shards, N=3 nodes, adding node-3 migrates `~16` shards. Each migration reads only that shard's documents (roughly `total_docs / 64` documents per shard), not the full node corpus. Total data moved is approximately `total_docs / 4` — the theoretical optimum for a 4-node cluster.\n925-\n926----\n927-\n928-## 5. API Surface and Compatibility\n929-\n930-Miroir exposes the Meilisearch REST API verbatim. All request and response shapes, status codes, error formats, and headers must match the Meilisearch spec exactly.\n931-\n932-### Routing by operation type\n933-\n934-**Broadcast to all

Body: `{\"queries\": [ {indexUid, q, ...}, ... ]}`. Each query is scattered independently and returned in input order.\n897-- `POST /indexes/{uid}/explain` — query plan API (§13.20). Same body as `/search`. Returns the orchestrator's resolved plan without executing; `?execute=true` additionally runs the plan and returns the real result.\n898-\n899-Both endpoints are listed here for discoverability; their routing behavior is summarized in the §5 \"Routing by operation type\" buckets.\n900-\n901-### Rebalancer\n902-\n903-Runs as a background Tokio task. Only one Miroir instance runs the rebalancer at a time (advisory lock in SQLite/Redis).\n904-\n905-The rebalancer relies on `_miroir_shard` being a filterable attribute on every node (set at index creation). This allows targeted retrieval of exactly the documents belonging to a given shard without scanning the entire node index.\n906-\n907-**Migration flow for node addition:**\n908-1. Compute `affected_shards`: shards where the new node enters the top-RF (expected count: `~S/(N+1)`)\n909-2. Begin dual-write: route new inbound writes for affected shards to both old owner and new node\n910-3. For each affected shard, paginate source node using the shard filter — no full scan required:\n911- ```\n912- GET /indexes/{uid}/documents?filter=_miroir_shard={shard_id}&limit=1000&offset=0\n913- GET /indexes/{uid}/documents?filter=_miroir_shard={shard_id}&limit=1000&offset=1000\n914- ... (until exhausted)\n915- ```\n916-4. Write each page to the new node (documents already carry `_miroir_shard`)\n917-5. Once all pages transferred, mark node `active` for those shards\n918-6. Stop dual-write; delete the migrated shard from the old node:\n919- ```\n920- POST /indexes/{uid}/documents/delete {\"filter\": \"_miroir_shard = {shard_id}\"}\n921- ```\n922-7. Documents on unaffected shards are never read, written, or touched\n923-\n924-**Performance**: with S=64 shards, N=3 nodes, adding node-3 migrates `~16` shards. Each migration reads only that shard's documents (roughly `total_docs / 64` documents per shard), not the full node corpus. Total data moved is approximately `total_docs / 4` — the theoretical optimum for a 4-node cluster.\n925-\n926----\n927-\n928-## 5.

Body: `{\"queries\": [ {indexUid, q, ...}, ... ]}`. Each query is scattered independently and returned in input order.\n897-- `POST /indexes/{uid}/explain` — query plan API (§13.20). Same body as `/search`. Returns the orchestrator's resolved plan without executing; `?execute=true` additionally runs the plan and returns the real result.\n898-\n899-Both endpoints are listed here for discoverability; their routing behavior is summarized in the §5 \"Routing by operation type\" buckets.\n900-\n901-### Rebalancer\n902-\n903-Runs as a background Tokio task. Only one Miroir instance runs the rebalancer at a time (advisory lock in SQLite/Redis).\n904-\n905-The rebalancer relies on `_miroir_shard` being a filterable attribute on every node (set at index creation). This allows targeted retrieval of exactly the documents belonging to a given shard without scanning the entire node index.\n906-\n907-**Migration flow for node addition:**\n908-1. Compute `affected_shards`: shards where the new node enters the top-RF (expected count: `~S/(N+1)`)\n909-2. Begin dual-write: route new inbound writes for affected shards to both old owner and new node\n910-3. For each affected shard, paginate source node using the shard filter — no full scan required:\n911- ```\n912- GET /indexes/{uid}/documents?filter=_miroir_shard={shard_id}&limit=1000&offset=0\n913- GET /indexes/{uid}/documents?filter=_miroir_shard={shard_id}&limit=1000&offset=1000\n914- ... (until exhausted)\n915- ```\n916-4. Write each page to the new node (documents already carry `_miroir_shard`)\n917-5. Once all pages transferred, mark node `active` for those shards\n918-6. Stop dual-write; delete the migrated shard from the old node:\n919- ```\n920- POST /indexes/{uid}/documents/delete {\"filter\": \"_miroir_shard = {shard_id}\"}\n921- ```\n922-7. Documents on unaffected shards are never read, written, or touched\n923-\n924-**Performance**: with S=64 shards, N=3 nodes, adding node-3 migrates `~16` shards. Each migration reads only that shard's documents (roughly `total_docs / 64` documents per shard), not the full node corpus. Total data moved is approximately `total_docs / 4` — the theoretical optimum for a 4-node cluster.\n925-\n926----\n927-\n928-## 5.

Currently covers `_miroir_shard` (always reserved) and `_miroir_updated_at` (reserved only when the anti-entropy reconciler of §13.8 is enabled; otherwise client-supplied values in that field are preserved and passed through untouched).\n976-- `miroir_idempotency_key_reused` — `Idempotency-Key` reused with a different request body (HTTP 409). See §13.10.\n977-- `miroir_settings_version_stale` — no covering set could be assembled after excluding nodes whose `node_settings_version` is below the client's `X-Miroir-Min-Settings-Version` floor (HTTP 503). See §13.5.\n978-- `miroir_multi_alias_not_writable` — client write targeted a multi-target alias managed by §13.17 ILM (HTTP 409). See §13.7.\n979-- `miroir_jwt_invalid` — bearer token parsed as a JWT but failed validation (bad signature, expired, wrong `kid`/`alg`, or malformed claims) (HTTP 401). See §13.21 and \"Bearer token dispatch\" below.\n980-- `miroir_jwt_scope_denied` — JWT signature, expiry, and index-binding are valid, but the token's `scope` array does not include the action for this method+path combination, or the `idx` claim does not match the target index (HTTP 403). Enforced orchestrator-side before any node call; see §13.21.\n981-- `miroir_invalid_auth` — credentials did not match any expected key (master, admin, or valid search UI JWT) on an auth-gated endpoint (HTTP 401).

UI)\n3175\t\n3176\t**Problem.** Developers integrating Meilisearch into a product need to build a frontend: search bar, results, facets, pagination, instant-search, mobile-friendly behavior. Even with client SDKs, this is weeks of careful UX work. For many use cases — internal tools, knowledge bases, docs search, catalog browsers, demos, MVPs — a great default UI is all that is needed. Miroir ships one.\n3177\t\n3178\t**Mechanism.** A single-page application embedded in the Miroir binary via `rust-embed`. Served at `/ui/search/{index}`. Authentication is brokered by the orchestrator — see \"Authentication model\" below; the SPA never holds a Meilisearch master or node key. Configuration is per-index via `POST /_miroir/ui/search/{index}/config`:\n3179\t\n3180\t**Authentication model.** The SPA never sees a Meilisearch master or node key. Instead Miroir brokers access through a two-layer credential chain:\n3181\t\n3182\t1. **Scoped Meilisearch key (orchestrator-held, rotated).** When the search UI is first enabled for an index, the orchestrator creates a **scoped search-only key** on every Meilisearch node via `POST /keys` (admin action, performed on behalf of the operator). The key's actions are limited to `[\"search\"]` and its `indexes` list is restricted to the UI-configured index (or the concrete UIDs behind a multi-target alias). The key carries a hard expiration of `scoped_key_max_age_days` (default 60d) and is automatically rotated by the orchestrator `scoped_key_rotate_before_expiry_days` (default 30d) before expiry: a new key is minted, promoted to primary, and the old key is revoked via `DELETE /keys/{old_uid}` only after all orchestrator pods have observed the rotation (same handoff pattern as the `nodeMasterKey` rotation in §9).\n3183\t\n3184\t **Scoped-key rotation coordination.** Rotation is a multi-pod handoff that must never revoke the old key while any peer is still serving requests against it. Coordination uses three pieces of shared state:\n3185\t - **Shared-key record.** A Redis hash at `miroir:search_ui_scoped_key:` with fields `{primary_uid, previous_uid, rotated_at, generation}`. On every inbound SPA request, the pod substitutes `primary_uid` as the Meilisearch authorization when forwarding; it additionally accepts `previous_uid` as a valid fallback during the overlap window (in case a just-restarted pod still references the old UID it read a moment earlier). `generation` is a monotonic counter bumped on each rotation.\n3186\t - **Leader lease.** Rotation is driven by a single leader holding the `search_ui_key_rotation:` lease (Mode B, §14.5). Only the leader mints the new scoped key, updates the hash, and later revokes `previous_uid`.\n3187\t - **Per-pod observation beacon.** Each pod writes `miroir:search_ui_scoped_key_observed:: = {generation, observed_at}` with 60 s TTL, refreshed on every use of the scoped key. This gives the leader a reliable \"who has seen what\" view of the fleet.\n3188\t\n3189\t **Revocation safety gate.** Before the leader revokes `previous_uid`, it enumerates the live peer set (from the §14.5 Mode B peer-discovery channel) and checks that every live peer has reported observation of the new `generation` on its beacon. Only when the intersection covers the entire peer set does the leader call `DELETE /keys/{previous_uid}` on every Meilisearch node. A peer that disappears (pod restart / rescheduling) before reporting the new generation is tolerated — its next startup will read the hash fresh, skipping the old UID entirely. The leader waits up to `scoped_key_rotation_drain_s` (default 120 s) for stragglers before retrying on the next rotation tick.\n3190\t\n3191\t **Trigger.** Rotation is triggered automatically `scoped_key_rotate_before_expiry_days` before the current key's expiry. With the defaults (`scoped_key_max_age_days: 60`, `scoped_key_rotate_before_expiry_days: 30`), a key issued today expires in 60 days and the next rotation fires ~30 days from now. A manual trigger is available via `POST /_miroir/ui/search/{index}/rotate-scoped-key` (admin-gated); the endpoint simply bumps a \"rotate-now\" flag on the hash that the leader picks up on its next tick. The `force: true` path on that endpoint bypasses the `scoped_key_rotate_before_expiry_days` timing gate entirely and rotates immediately regardless of how recent the current key is.\n3192\t\n3193\t **Config validation.** The Helm chart's `values.schema.json` rejects configurations where `scoped_key_rotate_before_expiry_days >= scoped_key_max_age_days` at install time, with a clear error message — such a configuration would cause rotation to fire immediately (or before) key issuance, producing a continuous rotation loop. The two values must satisfy `0 < scoped_key_rotate_before_expiry_days < scoped_key_max_age_days`, typically with a comfortable margin (the defaults give a 30-day active window between issuance and the rotation trigger).\n3194\t2. **Short-lived session token (browser-held).** The SPA retrieves a short-lived **session token** via `GET /_miroir/ui/search/{index}/session` which returns `{token, expires_at, index, rate_limit}`. The token is a JWT signed by the orchestrator's JWT secret (loaded from the env var named in `search_ui.auth.jwt_secret_env`, default `SEARCH_UI_JWT_SECRET`). Default TTL: 15 minutes. The SPA then calls `/indexes/{uid}/search` with `Authorization: Bearer `; Miroir validates the JWT server-side, rejects it on signature/expiry/index-mismatch, and **substitutes the orchestrator's scoped Meilisearch key** before forwarding to nodes. The scoped node key never leaves the orchestrator. Rotation of the signing secret is documented in §9 \"JWT signing-secret rotation\".\n3195\t\n3196\t **Scope and index claims (defense-in-depth).** JWT claims include `scope: [\"search\", \"multi_search\", \"beacon\"]` (array of allowed action names) and `idx: ` (the single index this session is bound to). The orchestrator validates on every request **before any node call**: the (method + path) must match an allowed action in `scope`, and the target index must equal `idx`. The mapping from (method, path) to action names is:\n3197\t - `POST /indexes/{idx}/search` → `search`\n3198\t - `POST /multi-search` → `multi_search` (every sub-query's `indexUid` must equal `idx`)\n3199\t - `POST /_miroir/ui/search/{idx}/beacon` → `beacon`\n3200\t\n3201\t Any other combination returns `miroir_jwt_scope_denied` (HTTP 403). This is a belt-and-braces check on top of the scoped Meilisearch key's own `actions: [\"search\"]` restriction: the orchestrator rejects disallowed combinations before the node sees the request, which matters for endpoints Meilisearch itself does not gate (e.g. the Miroir-side `beacon` endpoint).\n3202\t\n3203\t **JWT claim shape:**\n3204\t ```json\n3205\t {\n3206\t \"iss\": \"miroir\",\n3207\t \"sub\": \"search-ui-session\",\n3208\t \"idx\": \"products\",\n3209\t \"scope\": [\"search\", \"multi_search\", \"beacon\"],\n3210\t \"exp\": 1712345678,\n3211\t \"iat\": 1712344778,\n3212\t \"kid\": \"key-id\",\n3213\t \"injected_filter\": \"tenant IN [\\\"g1\\\",\\\"g2\\\"]\"\n3214\t }\n3215\t ```\n3216\t `injected_filter` is only present in `oauth_proxy` mode — see \"Filter injection in `oauth_proxy` mode\" below.\n3217\t3. **Authentication modes** (selectable per deployment via `search_ui.auth.mode`):\n3218\t - **`public`** — `GET /_miroir/ui/search/{index}/session` is unauthenticated but rate-limited by source IP (default `10/minute`); suitable for truly public search where anyone on the internet should be able to query.\n3219\t - **`shared_key`** — client must include `X-Search-UI-Key: ` (op-supplied, loaded from env var named by `search_ui.auth.shared_key_env`) to obtain a token; suitable for \"somewhat private\" deployments (internal tools reachable on VPN, staging previews, etc.). The shared key is embedded in first-party host pages by the operator; the SPA itself never hardcodes it.\n3220\t - **`oauth_proxy`** — the session endpoint expects upstream auth headers (`X-Forwarded-User`, `X-Forwarded-Groups` by default, overridable via `search_ui.auth.oauth_proxy.user_header` / `groups_header`) injected by an auth proxy like oauth2-proxy sitting in front of Miroir. Tokens carry the user and group claims so downstream filter injection (e.g. `tenant IN [user's groups]`) can enforce per-user access control — see \"Filter injection in `oauth_proxy` mode\" below. Requests missing the expected headers are rejected 401.\n3221\t4. **Origin restriction.** The session endpoint honors `search_ui.allowed_origins` (default `[\"*\"]` in `public` mode, empty in `shared_key` / `oauth_proxy` modes unless explicitly set); browser requests whose `Origin` header is not listed are rejected 403. `null` origin (file://) is always rejected outside `public` mode.\n3222\t5. **Never embed any Meilisearch master or node key in the SPA, HTML responses, meta tags, or JavaScript globals.** Only the ephemeral JWT session token may reach the browser, and only by way of the session endpoint.\n3223\t\n3224\tCross-reference §9 Secrets Handling for the `SEARCH_UI_JWT_SECRET` and `search_ui_shared_key` inventory entries; the orchestrator reads both from env at startup and refuses to enable the search UI if `SEARCH_UI_JWT_SECRET` is missing.\n3225\t\n3226\t**Per-index configuration.** The `search_ui` configuration is a list of per-index entries POSTed to `/_miroir/ui/search/{index}/config`.
