…torage - src/git/: pure functions for blob/tree/commit SHA computation, byte-for-byte compatible with real Git. 38 oracle tests against git CLI. - src/storage/repo-types.ts: TypeScript types for the full repo state model (three-snapshot model, flat path maps, merge state, refs). - src/storage/repo-db.ts: IndexedDB persistence layer with clean async API. 29 tests covering roundtrip, multi-repo isolation, file ops. - docs/vibenote-git-sync-design.md: design doc for the git sync rebuild. Tasks: git-object-identity (done), repo-state-storage (done)

- src/sync/sync-engine.ts: New sync engine implementing the design from vibenote-git-sync-design.md. Operates on RepoState types with a clean GitHubRemote adapter interface. - Sync flow: fetch remote → diff against BASE → three-way merge → commit → push → retry - Merge policies: markdown (custom 3-way via Yjs), binary (theirs wins), other text (remote wins as fallback) - Handles all cases: no-op, local-only push, remote-only pull, both-changed merge, race condition retry (max 3) - 19 tests covering all sync scenarios with in-memory mock GitHub remote Task: sync-engine (done)
- src/sync/github-adapter.ts: Implements GitHubRemote interface against GitHub REST API. Clean adapter bridging sync engine to real backend. - src/data/repo-state-store.ts: Reactive in-memory store wrapping RepoState. Provides file operations (create, rename, move, delete, save) with React subscription model. V2 replacement for localStorage-based LocalStore. - 21 tests for RepoStateStore (file ops, folders, subscriptions, state mgmt) - All modules type-check cleanly, full test suite passes (279 tests) Tasks: wire-app-data-v2 (done)
- src/data/storage-pruning.ts: Policy module that evicts locally-cached files that are fully synced with the remote and haven't been accessed recently. - Supports maxFiles, maxBytes, minAgeMs, and pinnedPaths constraints. - Only evicts files whose blob SHA matches the BASE snapshot (safe to re-fetch). - Evicts oldest files first. - 11 tests covering all pruning scenarios. - Full suite: 290 tests pass, type check clean. Task: storage-pruning (done)

What
Foundation for the data layer V2 rebuild. Two independent pieces built in parallel:
Git object identity library (
src/git/)Pure functions for blob/tree/commit SHA computation, byte-for-byte compatible with real Git. Includes flat-path-map → nested tree reconstruction. 38 tests oracle-verified against
gitCLI.Repo state model + IndexedDB storage (
src/storage/repo-*.ts)TypeScript types for the full repo state model (three-snapshot model: BASE/REMOTE/LOCAL, flat path maps, merge state, refs). IndexedDB persistence with clean async API. 29 tests.
Design doc
docs/vibenote-git-sync-design.md— captures the full design direction for the local git model and sync flow.Next steps
Builds on #104.
