Implements cross-index PK set + content hash comparator for online
resharding. Once backfill completes, the verify phase compares the
live and shadow indexes to ensure data consistency before alias swap.
Key implementation:
- Iterates every shard of live (old_shards) and shadow (new_shards)
via filter=_miroir_shard={id} paginated scan
- Streams PKs + content fingerprints into PK-keyed xxh3 buckets
(reuses §13.8's bucketed-Merkle machinery with PK-keyed bucketing
instead of shard-keyed, enabling comparison across different S)
- Asserts: (a) live PK set == shadow PK set, (b) content_hash matches
- Returns VerificationResults with discrepancies if any
Acceptance criteria:
- Live PK set size equals shadow PK set size
- Zero PKs only in live index
- Zero PKs only in shadow index
- Zero PKs with content hash mismatch

- Query planner integration for PK-narrowed queries (plan §13.4)
- Auth scope filtering (master_key vs admin_key warnings)
- ?execute=true parameter for plan+result in one call
- Warnings for unfilterable attributes and anti-patterns
- Broadcast pending detection during settings updates
Changes:

- Implement explain_search handler with full plan §13.20 features
Closes: miroir-uhj.20
Implements ILM rollover for time-series indexes with automatic index creation,
alias flipping, and retention cleanup. The implementation includes:
**Core Components:**
- IlmManager: manages policies and spawns IlmWorker on leader pod
- IlmWorker: background evaluator that runs periodic rollover checks
- IlmCoordinator: Mode B leader with phase state persistence
**Rollover Execution:**
1. Trigger evaluation (max_docs, max_age, max_size_gb)
2. Index creation on all nodes with template settings
3. Atomic write alias flip to new index
4. Multi-target read alias update (last N indexes)
5. Retention cleanup with safety lock (refuses to delete indexes newer than safety_lock_older_than_days)
**CDC Integration:**
- Rollover writes tagged with origin="rollover" for CDC suppression
- ORIGIN_ROLLOVER constant exported for use in WriteRequest
**Safety Features:**
- Safety lock prevents accidental deletion of recent indexes
- Multi-target aliases are ILM-managed only (operator PUT returns 409 miroir_multi_alias_not_writable)
- Leader-only singleton coordination via Mode B
**Acceptance Criteria Met:**
- max_docs trigger fires: new index created, write alias flipped, old index readable via multi-target read alias
- keep_indexes: N: (N+1)th oldest index deleted, queries no longer return its hits
- safety_lock_older_than_days blocks deletion of indexes newer than threshold with clear log line
- Multi-target alias writes rejected with 409 miroir_multi_alias_not_writable
All 9 ILM tests pass.
Closes: miroir-uhj.17
Implements async shadow traffic to staging clusters for comparison:
- Completes TODOs in shadow.rs: compute symmetric diff (hit IDs only in shadow)
- Adds admin API endpoints: GET /_miroir/shadow/diff, GET /_miroir/shadow/stats
- Adds shadow_manager to AppState for admin endpoint access
- Adds acceptance tests: 5% sampling rate, ring buffer bounds, operations filter
Key features:
- Stateles per-request scaling via local RNG
- Shadow failures never impact primary (timeout budget enforced)
- Ring buffer evicts oldest when full (in-memory only, per plan §4)
- Only search/multi_search/explain operations shadowed (writes excluded)
Acceptance criteria met:
- 5% sampling rate verified in test (±2% tolerance over 10K queries)
- Ring buffer bounded and evicts oldest entries
- Operations filter enforces write exclusion

Closes: miroir-uhj.16
- Implement process_reshard_chunk with actual document pagination
- Use _miroir_shard filter to fetch documents from live index
- Re-hash documents under new shard configuration
- Write to shadow index with X-Miroir-Origin: reshard_backfill header (CDC suppressed)
- Support throttling and progress tracking for idempotent resume
- Add unit tests for reshard backfill parameters and validation
Closes: miroir-uhj.1.3
Implements plan §13.1 step 2: dual-hash dual-write during resharding.
When an index is in resharding dual-write phase (shadow exists),
every write routes to BOTH live (hash %S_old) AND shadow (hash %S_new)
indexes, each with its own _miroir_shard tag. Shadow writes are tagged
with origin="reshard_backfill" for CDC suppression (plan §13.13).
Changes:
- Add ReshardingRegistry to track active resharding operations
- Add ReshardOperationState for dual-write detection
- Add prepare_dual_write_documents() to separate live/shard batches
- Modify write_documents_impl to check resharding registry
- Add shadow index write path with origin tagging
- Add ReshardingRegistry to AppState for write path access
Tests:
- 15 ReshardingRegistry tests covering register, get, update, remove
- 4 dual_write tests for document preparation logic
Closes: miroir-uhj.1.2
Implements plan §13.1 step 1: create shadow index {uid}__reshard_{S_new}
on every node and propagate live index settings via two-phase broadcast
(§13.5).
Key changes:
- Add ShadowCreateResult struct to return creation results
- Add ShadowCreateError enum for failure handling
- Implement shadow_create_phase() function that:
1. Creates shadow index sequentially on all nodes
2. Fetches live index settings
3. Ensures _miroir_shard is in filterableAttributes
4. Runs two-phase settings broadcast
5. Rollback on any failure (shadow not client-addressable yet)
- Add helper functions: create_index_on_node, fetch_index_settings,
ensure_shard_filterable, two_phase_broadcast_settings, rollback_shadow_index
- Add unit tests for shadow create phase
Acceptance criteria:
- Shadow index created on every node with new shard count
- Settings propagated via two-phase broadcast
- Rollback on failure (invisible to clients)

Implements plan §2 topology changes and §4 rebalancer with full elastic
cluster operations: node addition/removal, replica group management, and
unplanned failure handling.
Core changes:
- topology.rs: Add GroupState::Draining for group removal flow
- router.rs: query_group_active() excludes draining groups via is_routing()
- scatter.rs: Health filtering with cross-group fallback for failed nodes
- rebalancer.rs: Add handle_node_recovery() for RF restore after recovery
- main.rs: Unplanned node failure detection with consecutive failure/success
tracking, automatic Degraded/Failed transitions, and recovery event triggers
Admin API:
- POST /_miroir/nodes/{id}/recover - Mark failed node as recovered
- DELETE /_miroir/nodes/{id} - Remove node (after drain)
- POST /_miroir/nodes/{id}/drain - Start node drain for removal
- POST /_miroir/nodes/{id}/fail - Mark node as failed
- POST /_miroir/replica_groups - Add replica group
- GET /_miroir/replica_groups/{id}/status - Group sync progress

All Definition of Done criteria verified:
- 1000 documents indexed across 3 nodes, each retrievable by ID
- Unique-keyword search finds every doc exactly once
- Facet aggregation across 3 color values sums correctly
- Offset/limit paging preserves global ordering
- Write with one group completely down still succeeds with X-Miroir-Degraded header
- Error-format parity: all miroir_* codes match Meilisearch shape
- GET /_miroir/topology matches plan §10 shape
60 integration tests pass covering write path, read path, index lifecycle,
task reconciliation, and error format parity.
## Retrospective
- **What worked:** The state machine approach with clear phase transitions (Initializing → Syncing → SyncComplete → Active) made the flow easy to understand and test. Separating the coordinator from the sync worker allowed for clean testing.
- **What didn't:** Initial implementation had the sync worker running in a tight loop; needed to add configurable intervals and proper timeout handling.
- **Surprise:** The query routing already filtered by group state, so the 'queries NOT routed to initializing groups' requirement was already satisfied by existing logic.
- **Reusable pattern:** For future multi-phase operations, use a Coordinator + Worker pattern where the coordinator manages state/progress and the worker performs the actual work with periodic checkpoints.
Implements plan §2 "Adding a new replica group (throughput scaling)":
Core components:
- GroupAdditionCoordinator: Manages group addition state machine
(Initializing → Syncing → SyncComplete → Active)
- GroupSyncWorker: Background worker that copies documents from source
groups to new group via pagination with filter=_miroir_shard={id}
- GroupState enum: Tracks Initializing vs Active state for replica groups
- query_group_active(): Routes queries only to active groups, skipping
initializing groups during sync
Key features:
- Round-robin source group selection across active groups to spread load
- Write fan-out to new group begins immediately during sync (durability
guarantee - only historical data is transient until sync completes)
- Per-shard sync progress tracking for pause/resume (Phase 6 Mode C)
- Failed sync pauses without corrupting new group; resumes when source returns
Acceptance criteria met:
- RG=1 → RG=2: During sync, queries route only to active group (no regression)
- After active: queries distribute round-robin between both groups
- Mid-sync writes: fan out to both groups immediately
- Failed sync: pauses gracefully, resumes on source recovery

The test_task_registry_impl_captures_all_node_tasks test was failing
because TaskRegistryImpl::register_with_metadata() uses
tokio::task::block_in_place() internally, which requires a
multi-threaded tokio runtime.

test so it runs with a proper multi-threaded runtime.

## What
- Idempotency cache for write deduplication with SHA256 body hashing
- Query coalescing for identical concurrent search requests
- Config options for TTL, max entries, coalescing window, max subscribers
## Why
HTTP retries, SDK retry loops, and at-least-once delivery produce duplicate writes.
Hot identical search queries waste caching opportunities.
## Details
- Accept Idempotency-Key header for writes
- Return cached mtask ID on hit, 409 conflict on key reuse with different body
- Query fingerprint includes canonical JSON + index UID + settings version
- Settings change invalidates in-flight coalesce (settings_version in fingerprint)
- 50ms default coalescing window closes at response time
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Fixed ownership issues in idempotency/coalescing tests:
- Add .clone() when passing QueryFingerprint to methods that take ownership
- Remove unused imports (canonicalize_json, Result)
- Prefix unused loop variable with underscore
All 11 acceptance tests now pass:
- p5_10_a1: Same key + same body → cached mtask
- p5_10_a2: Same key + different body → 409 conflict
- p5_10_a3: Hot query coalescing (1000 concurrent)
- p5_10_a4: Settings version invalidation
- p5_10_a5: TTL and max entries enforcement

- Paging with no dupes/gaps
- Node down with RF=2 covers all shards
- Group fallback succeeds (not degraded)
- X-Miroir-Degraded header includes shard IDs
- Integration test with all features
- showRankingScore injected unconditionally
- limit is offset + limit for coordinator pagination
- Degraded header format verification
