tests/test_doors.py detects 5/10 door-breaking mutants, four on the fast tier and one only on the slow tier, and the five escapes share one cause: the guard reads only the docs/doors/README.md table for the regex scripts/[\w.]+\.py.

Which door-breaking mutants does tests/test_doors.py detect, and which pass it?
Method & Verification
Ten mutants were applied to throwaway git worktrees, both pytest tiers were recorded, and a tree carrying all five escapes at once stayed green on both tiers.
Lineage & Relationships
None

Editorial Notes
Handback em dashes were rewritten as colons. RESULTS status says settled at the level a mutation battery can settle it; case log says probe, complete. Disposition maps to completed. The proposed ledger amendment was reported and not applied.
