+# M13-05C Status
+
+status: done  
+task: production/build/test dependency inventories  
+updated: 2026-08-19 America/New_York  
+enablingTask: false  
+parityStateChange: false
+
+## Evidence
+
+`web/package.json` and `web/package-lock.json` are parsed as the only dependency sources. Deterministic
+transitive closures contain production=3, build=135 and test=6 packages; every package is classified and
+records its path, version, resolved URL and lockfile integrity. A fresh regeneration is byte-identical.
+
+- `npm --prefix web run test:dependency-inventory` passed.
+- `npm --prefix web run typecheck` passed.
+- `npm --prefix web run build` passed.
+- `git diff --check` passed.
+
+## Next Task
+
+`M13-05D`: severity gates and documented dependency exceptions.
+
+## Rollback
+
+Remove the inventory generator/checker, report, manifest, package command and this status; restore
+`M13-05B` as the queue tail.
