+# 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`.
