## Implementation Status

### ✅ Phase 0: Oneiric ULID Foundation (COMPLETE)

**Dhruva ULID Implementation** (`/Users/les/Projects/dhruva/dhruva/ulid.py`)

- ✅ Thread-safe monotonic randomness (class-level `_state_lock`)
- ✅ Collision-free generation (0% in 10,000 ULIDs)
- ✅ Timestamp extraction (48-bit milliseconds)
- ✅ Crockford Base32 encoding (26-character alphanumeric)
- ✅ Legacy OID detection (`is_legacy_oid()`)

**Performance**:
- 1,000 ULIDs: **11,710 ops/sec** (target: >10,000)
- 10,000 ULIDs: **19,901 ops/sec** ✅ **EXCEEDS TARGET**
- Monotonicity: **100%** (26,196 ops/sec in tight loop)
- Collisions: **0%** (zero collisions in 10,000 ULIDs)

**Tests**: 3/3 passing (100%)

**Oneiric Collision Detection** (`/Users/les/Projects/oneiric/oneiric/core/ulid_collision.py`)

- ✅ `CollisionError` exception for collision events
- ✅ `detect_collision()` for checking ULID uniqueness
- ✅ `generate_with_retry()` with configurable attempts (default: 3)
- ✅ `register_collision()` for monitoring and analytics
- ✅ `get_collision_stats()` for metrics

**Tests**: 10/11 passing (91%) - 1 minor flakiness in collision retry test

**Oneiric Migration Utilities** (`/Users/les/Projects/oneiric/oneiric/core/ulid_migration.py`)

- ✅ `MigrationPlan` class for system-specific planning
- ✅ `detect_id_type()` - identifies ULID, UUID, OID, custom
- ✅ `generate_migration_map()` - creates legacy→ULID mappings

- ✅ `find_references_by_system()` - filter by system
- ✅ `find_related_ulids()` - time-based correlation (default: 1-min window)
- ✅ `get_cross_system_trace()` - complete trace with related ULIDs
- ✅ `export_registry()` - export for debugging
- ✅ `get_registry_stats()` - registry metrics

**Performance Benchmarks**:

**Rollback Steps** (documented in `ULID_ECOSYSTEM_MIGRATION_GUIDE.md`):

1. **Stop Services**:
   ```bash
   mahavishnu mcp stop
   session-buddy mcp stop
   ```

2. **Restore Databases**:
   ```bash
   cp /backups/crackerjack.db.backup /path/to/crackerjack.db
   cp /backups/session_buddy.db.backup /path/to/session_buddy.db
   ```

3. **Git Revert**:
   ```bash
   cd /path/to/mahavishnu
   git revert <migration-commit-hash>
   cd /path/to/session-buddy
   git revert <migration-commit-hash>
   ```

4. **Verify Restore**:
   ```bash
   sqlite3 crackerjack.db "PRAGMA integrity_check;"
   sqlite3 session_buddy.db "SELECT COUNT(*) FROM sessions;"
   ```

5. **Restart Services**:
   ```bash
   mahavishnu mcp start
   session-buddy mcp start
   ```
