Fixed critical bug where CommitObject.walk() didn't guard against NULL parent hash, causing "Blob metadata not found: 0000...0000" error when calling getHistory() on fresh databases. This is a SYSTEMATIC fix, not just a patch: Infrastructure: - src/storage/cow/constants.ts: NEW - NULL_HASH constant and utilities - Prevents hardcoding errors - Provides isNullHash() for semantic checks Bug Fixes: - src/storage/cow/CommitObject.ts: Guard NULL parent in walk() - src/storage/cow/BlobStorage.ts: Defensive check rejects NULL hash reads - src/storage/baseStorage.ts: Use NULL_HASH constant (not hardcoded) - src/brainy.ts: Use NULL_HASH constant (not hardcoded) Testing: - tests/integration/initial-commit-null-parent.test.ts: 5 regression tests - All 17 tests pass (5 new + 12 existing COW tests) - Zero regressions This fix addresses the root cause of 4 consecutive bugs (v5.3.0-v5.3.3): missing defensive programming for sentinel values in COW storage. Fixes: Workshop team bug report (v5.3.3 regression) Tests: 17/17 pass (5 new regression + 12 existing COW) Build: SUCCESSFUL (zero errors) |
