ba70cd25c0 P3: Complete Phase 3 — Task Registry + Persistence (SQLite + Redis) 
Implements all 14 tables from plan §4 with dual backend support.

## Implementation

### TaskStore Trait (502 lines)
- Complete API covering all 14 tables
- Runtime backend selection (sqlite | redis)

### SQLite Backend (2,536 lines)
- rusqlite-based with WAL mode
- Idempotent migrations (schema_versions table)
- 36 tests passing (proptest + integration)

### Redis Backend (3,884 lines)
- Full TaskStore trait implementation
- Uses `_index` sets for O(1) list queries (no SCAN)
- 33 integration tests (testcontainers)

### Schema Files
- 001_initial.sql: Tables 1-7
- 002_feature_tables.sql: Tables 8-14
- 003_task_registry_fields.sql: No-op marker

### Validation
- Helm values.schema.json enforces HA constraints:
  - replicas > 1 requires backend: redis
  - HPA requires replicas >= 2 + redis
- Verified with helm lint

### Documentation
- REDIS_MEMORY_ACCOUNTING.md: Complete sizing guide

## Definition of Done — Complete
✅ rusqlite store with idempotent table initialization
✅ Redis store mirrors TaskStore API
✅ Migrations/versioning with schema_version row
✅ Property tests (proptest) for SQLite
✅ Restart resilience integration tests
✅ Redis integration tests (testcontainers)
✅ `_index` pattern for list queries
✅ Helm schema enforces HA requirements
✅ Redis memory accounting (plan §14.7)

Total: 6,922 lines of production code + tests

ac80d1f765 P3: Phase 3 Task Registry + Persistence — COMPLETE 
Completes Phase 3 of the Miroir implementation: the 14-table task-store
schema from plan §4 with both SQLite and Redis backends.

## What Was Done

### 1. SQLite Backend (SqliteTaskStore)
- All 14 tables implemented with CRUD operations
- WAL mode for concurrent access
- Schema version tracking with migration system
- Idempotent migrations (safe to run on every startup)
- Schema version ahead detection (refuses to start if store > binary)

### 2. Redis Backend (RedisTaskStore)
- All 14 tables mapped to Redis keyspace
- Hash per row + index sets for O(cardinality) iteration
- testcontainers-based integration tests
- Leader lease with Redis SET NX/EX semantics
- Pub/Sub for session revocation
- Memory budget test (plan §14.7)

### 3. Schema Migrations
- Migration 1: Core tables (1-7)
- Migration 2: Feature tables (8-14)
- Migration 3: Task registry fields (no-op)

### 4. Tests
- SQLite: 36 tests pass (CRUD, property tests, restart resilience)
- Redis: Comprehensive integration tests (testcontainers)
- Helm validation: multi-replica requires Redis enforced

### 5. Helm Validation
- values.schema.json enforces redis + multi-replica constraint
- Test cases verify lint behavior (pass/fail as expected)

## Definition of Done — VERIFIED ✅

- rusqlite-backed store initializing every table idempotently
- Redis-backed store mirrors the same API (TaskStore trait)
- Migrations/versioning with schema version tracking
- Property tests on SQLite backend
- Integration test: restart resilience
- Redis-backend integration test (testcontainers)
- miroir:tasks:_index-style iteration for list endpoints
- taskStore.backend: redis + replicas > 1 enforced by Helm
- Plan §14.7 Redis memory accounting validated

b14db53775 P4: Phase 4 topology operations verification — all chaos tests pass 
Verified Phase 4 (Topology Operations) is complete:

Chaos Tests (22/22 passing):
- chaos_add_node_mid_indexing — add node during indexing, all docs readable
- chaos_drain_node_while_querying — drain during queries, zero failures
- chaos_add_replica_group_while_querying — add group, existing groups unaffected
- chaos_rebalance_optimal_movement — ≤2×(1/4) doc movement for 3→4 nodes
- chaos_restart_node_mid_rebalance — failure during rebalance, resume on recovery
- chaos_rendezvous_determinism — rendezvous hash consistency
- chaos_cannot_remove_last_node — safety guard for last node
- chaos_cannot_remove_last_group — safety guard for last group
- Plus 14 cutover_race tests for dual-write safety

Implementation Complete:
- Rebalancer with add/remove/drain node and group operations
- MigrationCoordinator with dual-write + delta pass
- HttpMigrationExecutor for HTTP-based document migration
- Admin API endpoints (POST/DELETE /_miroir/nodes, /_miroir/replica_groups)
- CLI commands (miroir-ctl node add/remove/drain/list, rebalance status)

Test Results:
- Library tests: 262 passed
- Chaos tests: 22 passed
- Total: 284 tests passed
