-# Post-Audit Status Report (2026-04-15) - polyglot-formalisms-elixir
+# Post-audit Status Report: polyglot-formalisms-elixir
+- **Date:** 2026-04-15
+- **Status:** Complete (M5 Sweep)
+- **Repo:** /var/mnt/eclipse/repos/polyglot-formalisms-elixir
 
 ## Actions Taken
-- **Lockfile Generation:** Generated `mix.lock` using `mix deps.get`.
-- **Tool Versioning:** Updated `.tool-versions` to Erlang 28.3.1 and Elixir 1.19.5-otp-28 to match system availability and resolve `mix` command errors.
-- **Static Analysis:** Ran `panic-attack` on the repository.
+1. Standard CI/Workflow Sweep: Added blocker workflows (`ts-blocker.yml`, `npm-bun-blocker.yml`) and updated `Justfile`.
+2. SCM-to-A2ML Migration: Staged and committed deletions of legacy `.scm` files.
+3. Lockfile Sweep: Generated and tracked missing lockfiles where manifests were present.
+4. Static Analysis: Verified with `panic-attack assail`.
 
-## Static Analysis Findings
-- **High Severity:** `flake.nix` declares inputs without `narHash` or pinning.
-- **Low Severity:** Multiple `MutationGap` findings in test files (missing property-based tests).
-- **Low Severity:** `UncheckedError` in `contractiles/k9/template-hunt.k9.ncl` (14 TODO/FIXME/HACK markers).
+## Findings Summary
+- Elixir test file test/arithmetic_test.exs uses ExUnit.Case but has no ExUnitProperties/StreamData — add property-based tests to improve mutation coverage
+- Elixir test file test/comparison_test.exs uses ExUnit.Case but has no ExUnitProperties/StreamData — add property-based tests to improve mutation coverage
+- Elixir test file test/logical_test.exs uses ExUnit.Case but has no ExUnitProperties/StreamData — add property-based tests to improve mutation coverage
+- Elixir test file test/string_ops_test.exs uses ExUnit.Case but has no ExUnitProperties/StreamData — add property-based tests to improve mutation coverage
+- Elixir test file test/e2e/formalism_e2e_test.exs uses ExUnit.Case but has no ExUnitProperties/StreamData — add property-based tests to improve mutation coverage
+- 14 TODO/FIXME/HACK markers in contractiles/k9/template-hunt.k9.ncl
+- flake.nix declares inputs without narHash, rev pinning, or sibling flake.lock — dependency revision is unpinned in flake.nix
 
-## CRG Grade
-**Grade: D**
-(Lockfiles fixed, but significant static analysis findings remain).
+## Final Grade
+- **CRG Grade:** D (Promoted from E/X) - CI and lockfiles are in place.
