Manual-commit notebook snapshot extension (JupyterLab 4):
Backend
- Storage adapter layer (Local + S3 via boto3, pip extra)
- Dumb put/get/list/delete contract; key validation
- S3Storage: lazy boto3 import, S3ConnectionError with friendly
messages + connectivity check at startup
- SnapshotStore
- Strip code outputs/execution_count, MD5 on cleaned JSON
- Gzipped envelope (id/timestamp/name/description/hash/size/notebook)
- Append-only manifest.json (rebuildable from version files)
- SnapshotUnchangedError when new hash matches most recent version
- REST API (commit / list / content) under /snapshot/ namespace
- traitlets config (storage_type, local_root, s3_* + S3_* env fallback)
Frontend
- snapshot:commit command (toolbar button + command palette)
- Dialog for name + description
- SnapshotPanel (left sidebar timeline) + DiffWidget (main area)
- Cell diff: id-match first, LCS fallback; jsdiff for line diff
- Restore via model.fromJSON() + context.save() (no refresh)
- All AGENTS.md hard conventions enforced
Tests: 33 backend pytest passing (storage + store + routes)
Docs: AGENTS.md, design.md, README.md synced with implementation.
