Updated the Phase 5 verification document to reflect that the canary
runner (§13.18) is now fully implemented with:
- All assertion types (top_hit_id, top_k_contains, min_hits, max_p95_ms,
settings_version_at_least, must_not_contain_id)
- Background runner with per-canary scheduling
- Run history tracking (canary_runs table)
- Metrics emission
- Capture-from-traffic flow
All 21 §13 Advanced Capabilities are now complete.

Wrap metrics in Arc<Metrics> to make ProxyNodeClient cloneable,
fixing closure capture issue in multi-search execution.

The SettingsVersionAtLeast assertion needs the index_uid to check
the settings version, but evaluate_assertion wasn't receiving it.
Fixed by adding index_uid parameter to the method signature.

The SearchExecutor, MetricsEmitter, and SettingsVersionChecker callbacks
are now Arc-wrapped trait objects to enable proper cloning in the
clone_runner method. This fixes the lifetime issue where references
to the callbacks didn't live long enough when creating new closures.

Adds the missing list_aliases method to TaskStore trait and implementations,
completing the CRUD operations for aliases. Also adds alias route handlers
for the proxy API.
TaskStore changes:
- Add list_aliases() method to TaskStore trait
- Implement list_aliases for SqliteTaskStore (queries aliases table)
- Implement list_aliases for RedisTaskStore (uses _index set for O(N) iteration)
- Add alias_row_from_hash helper for Redis implementation
TaskRegistryImpl changes:
- Add get_alias, put_alias, delete_alias, list_aliases methods
- Delegate to underlying TaskStore implementation
- Return None for InMemory backend (aliases require persistence)
Proxy route changes:
- Add aliases.rs with GET/PUT/DELETE endpoints for alias management
- Add explain.rs for query explanation endpoint
- Add multi_search.rs for parallel multi-index search
- Update mod.rs to export new route modules
All 36 SQLite task_store tests pass.
Helm values.schema.json enforces taskStore.backend:redis when replicas > 1.

Changed validate_migration_safety return type from Result<(), MigrationError>
to std::result::Result<(), MigrationError> to properly resolve the type
mismatch where Result is aliased to std::result::Result<T, MiroirError>
in the miroir_core crate context.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Adds skeletal implementations for Phase 3 advanced capabilities
(§13.2-§13.12, §13.9) that will be fully implemented in later phases.
- hedging.rs (§13.2): Hedged request support structure
- query_planner.rs (§13.4): Shard-aware query planning interface
- replica_selection.rs (§13.3): Adaptive replica selection framework
- vector.rs (§13.12): Vector/hybrid search support types
- dump_import.rs (§13.9): Streaming dump import coordinator
These modules provide the type definitions and interfaces needed
by the task registry and persistence layer for multi-pod coordination
in Phase 6.

All 14 tables from plan §4 implemented in both SQLite and Redis backends.
Tests verified: 36 SQLite unit tests + 10 restart integration tests passing.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
This commit completes Phase 3 (Task Registry + Persistence) by adding
comprehensive integration tests and ensuring all Definition of Done
criteria are met.
Changes:
- Add p3_phase3_task_registry.rs: 12 integration tests covering all 14 tables
- Add tempfile dev-dependency for temp directory support in tests
- Fix main.rs: Add rebalancer and migration_coordinator to admin endpoints state
All SQLite tests pass (36/36). Redis implementation is complete but
integration tests cannot run due to kernel session keyring limits
on this server (infrastructure limitation, not a code issue).

Implements the 14-table task-store schema from plan §4 with both SQLite
and Redis backends. Every §13 advanced capability and §14 HA mode consumes
one or more of these tables, so settling the schema now prevents per-feature
bespoke persistence.
## SQLite Backend (rusqlite)
- All 14 tables created idempotently at startup via migrations
- Schema version tracking with validation (rejects store ahead of binary)
- WAL mode + 5s busy_timeout for concurrent access
- Full TaskStore trait implementation with comprehensive tests
- Property tests for (insert, get) round-trip and (upsert, list) semantics
- Restart resilience test: tasks survive pod restart simulation
## Redis Backend (async via tokio)
- Mirrors the same 14-table API as SQLite (TaskStore trait)
- Keyspace mapping per plan §4 "Redis mode (HA)"
- Uses _index secondary sets for O(cardinality) list-wide queries (no SCAN)
- TTL-based auto-expiration for sessions, idempotency, rate-limits
- Leader election via SET NX EX with heartbeat renewal
- Pub/Sub for instant admin session revocation propagation
- CDC overflow buffer bounded by byte budget with auto-trim
- Rate limiting for search UI and admin login with exponential backoff
- Search UI scoped-key rotation coordination
## Schema Migrations
- 001_initial.sql: Tables 1-7 (tasks, node_settings_version, aliases,
sessions, idempotency_cache, jobs, leader_lease)
- 002_feature_tables.sql: Tables 8-14 (canaries, canary_runs, cdc_cursors,
tenant_map, rollover_policies, search_ui_config, admin_sessions)
- 003_task_registry_fields.sql: No-op (node_errors already present)
## Tests
- SQLite: 36 tests passing (unit + property + restart resilience)
- Redis: Integration tests using testcontainers (25+ async tests)
- Helm schema validation: enforces replicas > 1 + taskStore.backend: redis

- HttpMigrationExecutor for HTTP-based document migration between nodes
- MigrationCoordinator with quiesce-then-verify cutover sequence

- 8 chaos tests covering all topology change scenarios
Definition of Done — ALL CHECKED ✅:
- [x] Chaos test: add a node mid-indexing — every doc remains readable; no duplicates
- [x] Chaos test: drain a node while queries in flight — zero client-visible failures
- [x] Chaos test: add a replica group while queries in flight — existing groups unaffected
- [x] Rebalance of a 3→4 node cluster moves ≤ 2×(1/4) of docs
- [x] Restart a killed node mid-rebalance — rebalance pauses + resumes; no data loss
