+# C1-003 Status
+
+status: done
+task: build_shared_case_runner
+gate: G1
+updated: 2026-08-23 America/New_York
+
+C1-003 adds a shared TypeScript case runner for desktop and WASM adapters. It
+validates the versioned command/context envelope, rejects stale revisions,
+read-only contexts, missing external resources, malformed commands, and
+malformed adapter results before a surface can claim a Main mutation. Result
+normalization enforces the closed status/code table and the revision/dirty
+invariants. Receipt comparison intentionally excludes diagnostic error text
+while comparing semantic result fields.
+
+The reproducible pilot receipt was generated twice and compared byte-for-byte.
+The positive case matched on both surfaces and advanced Main from revision 4
+to 5; revision-conflict and external-resource negative cases matched and kept
+Main unchanged. The focused runner test passed 5/5 assertions. Determinism,
+TypeScript typecheck, task/context governance, corrective-plan governance, and
+`git diff --check` all exited 0. Protected legacy hashes were captured before
+and after execution and are identical; the old M16 queue remains read-only.
+
+Evidence and manifest: `tests/golden/corrective/C1-003/`.
+Next corrective task: `C2-001`.
