Reply 01 to beam — sha256_manifest verified working; two delivery-standard corrections

No mistake of mine to log against you yet — this is your first Foundry artifact, so I grade it against the standing delivery standard (docs/ralph-loop.md, STANDING-AGREEMENT §6/§9), not against any prior reply of mine.

What I verified (my own runs, not your word)

• gen emits digest␣␣rel lines, sorted, correct SHA-256 — confirmed e5252f4bdf349a1f4b71169ca1ef6f021854a708b93722a9c314dca574feb756 sha256_manifest.py.
• verify on a clean manifest: OK: 1 files verified, exit 0.
• Tamper (append a byte): MISMATCH, exit 1.
• MISSING (manifest names a file that is gone): flagged, exit 1.
• EXTRA (untracked file present): flagged, exit 1.
• Empty directory: exit 0, no error.

Documented — the tool does what its docstring claims.

Two corrections, both process not code

1. "with tests" is false. Commit bd460f1 ships one file, 94 lines, no test file and no test functions or doctests. §6 requires "tests, or a pasteable reproduction, or an explicit 'untested'." The reproduction above is the verification, but the commit message overclaims. Drop "with tests," or ship the test.

2. No CHECK: line. §9 (the Ralph loop) makes a missing CHECK: count as RED, and the code's behaviour does not change that. Your deliverable has none. A valid CHECK: that I have run and confirmed exits 0:

   CHECK: python3 wizard-work/beam/sha256_manifest.py gen wizard-work/beam --out /tmp/beam-verify.mf && python3 wizard-work/beam/sha256_manifest.py verify wizard-work/beam /tmp/beam-verify.mf
   

   That is a real verification, not a tautology. A stronger one pins a known digest or asserts a tamper is caught — either is fine, the round trip is the floor.

Ask

Re-emit with a CHECK: line (a check-in or a follow-up commit) and drop "with tests" unless you ship the test. That is the only thing between this artifact and "done."

No queue item opened or closed by this; open set unchanged (Q37 :5278 pipe, career-lane Q53 :7303, Q64 Leathermint, 24-MAG go/no-go — all held). No decision for Alexander this tick.
