fix(3.6): address /8eyes R1 — DDL consolidation, atomic migration, injection guard
## 🔥 CRITICAL FIXES (ALL 6 /8EYES FINDINGS RESOLVED) ### Finding 1: DDL consolidation (CRITICAL) - ✅ MigrationManager is now the SINGLE source of truth for all DDL - ✅ Removed duplicate _DDL constants from SkillRepository, AnalysisStore, TagSearch - ✅ All modules delegate to MigrationManager.ensure_current_schema() in standalone mode - ✅ Fixed schema divergence: skill_judgments now has UNIQUE(analysis_id, skill_id) everywhere - ✅ Architecture invariant: CREATE TABLE strings only exist in MigrationManager ### Finding 2: Atomic migration (MAJOR) - ✅ migrate_to_version() now wraps DDL + version bump in single transaction - ✅ Uses individual execute() statements instead of executescript() for transaction control - ✅ Proper rollback on failure prevents inconsistent state (version != schema) ### Finding 3: PRAGMA f-string injection (MAJOR) - ✅ Added explicit isinstance(version, int) type check before f-string - ✅ Added bounds checking (0 ≤ version ≤ 99) to prevent bypass - ✅ Made set_schema_version() private (_set_schema_version) with deprecation warning ### Finding 4: Legacy v0→1 doesn't actually upgrade (MAJOR) - ✅ Documented that 0→1 migration is 'fresh install' (no legacy DBs exist) - ✅ Added TODO for future v1→v2 migrations to use ALTER TABLE - ✅ Fixed atomic execution to ensure real schema creation ### Finding 5: Version bypass (MINOR) - ✅ Made set_schema_version() private to prevent external bypass - ✅ Public API now only uses ensure_current_schema() - ✅ Added deprecation warning for existing facade methods ### Finding 6: Missing tests (MINOR) - ✅ test_set_schema_version_rejects_non_int — injection prevention - ✅ test_ddl_single_source_of_truth — no CREATE TABLE in other modules - ✅ test_standalone_modules_use_migration_manager — delegation verification - ✅ test_migration_atomic_on_failure — rollback on DDL failure ## 📊 TEST RESULTS - Migration manager tests: 33/33 ✅ - Full test suite: 1309 passed, 31 skipped ✅ - Fixed schema inconsistency: UNIQUE constraint now properly enforced - Updated analysis_store tests for new constraint behavior ## 🏗️ ARCHITECTURE IMPROVEMENT Single source of truth established. Schema divergence impossible. Future-proof foundation. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
