# C2-003 Status

status: done
task: undo_redo_save_invariants
gate: G2
updated: 2026-08-23 America/New_York

C2-003 adds a bounded corrective history store over the atomic Main store.
Commits create one undo snapshot and clear redo; undo/redo restore value,
revision, and dirty state; save records a clean snapshot; reopen restores that
snapshot and clears transient history. No-op commits do not create history
entries.

The focused history test passed 5/5 assertions. Desktop and WASM save/reopen
snapshots matched exactly. Deterministic receipt generation, protected legacy
hash comparison, typecheck, context/corrective governance, task-context, and
`git diff --check` all exited 0.

Evidence and manifest: `tests/golden/corrective/C2-003/`.
Next corrective task: `C3-001`.
