Classification

Draft Research Infrastructure / supervisor-only post-freeze comparison apparatus. Do not merge.

This PR exists to durably freeze the evaluator and comparison workflow before the context-free Consumer B implementation is launched. The fresh implementer is explicitly forbidden from inspecting this PR, branch, evaluator, workflow, or any prior Decision/Apparatus/CAL implementation/results before candidate freeze.

Exact freeze

  • protected Decision base: 7be709b2141c767c5da89b8b94cf90233c4238fe
  • frozen evaluator head: 97cb968ac8793adb575640404730399a8798ad98
  • clean-room sparse aperture commit in research-scaffold-harness: cb1d27ff00ae030093c5e97d78477cec7f20c6f4
  • aperture tree: 2fade6a19f1e199fd5d3412480badc3eac141eb2
  • hidden evaluator blob: cc1c507d81f5614ea76f1597d79099d51cd73e69
  • comparison workflow blob: ab4cdb9e59ce83563784f9b08813151b7df194b7
  • evaluator freeze receipt is committed on this branch

Final evaluator self-check:

  • run 34710510423
  • job 103598313958
  • Python compile: PASS
  • pinned aperture identities: PASS

Reveal boundary

Do not dispatch the comparison until a fresh executor returns a frozen candidate descended from exact aperture commit cb1d27ff00ae030093c5e97d78477cec7f20c6f4, with a clean freeze receipt and no forbidden pre-freeze exposure.

No Contract C version assignment, promotion, production Decision mutation, release, tag, Authorization, or execution is authorized here.

Post-freeze Consumer B comparison result

Fresh candidate evidence record: camerontjs-dot/research-scaffold-harness PR #29

Exact candidate:

  • implementation/test freeze: c1c31885f5802d4ea710dea7bcec214e977b9f03
  • receipt commit: 07e60447fae17369be5676f013c187b9fd0bfd98
  • consumer blob: 7c4e15855dfba57bdc2a23e98960e0d79d272aa6
  • test blob: 9000b495fd5d15f16dc82e662abe6764dc2b02f1
  • receipt blob: a2f75dff9ef4f1820a91331ee43e5ceb13d3a76e
  • contamination: CLEAN_PRE_FREEZE_APERTURE
  • prereveal tests: 21/21 PASS

Exact frozen evaluator remained at:

  • commit 97cb968ac8793adb575640404730399a8798ad98
  • evaluator blob cc1c507d81f5614ea76f1597d79099d51cd73e69

Decisive comparison:

  • Actions run 34717144897
  • job 103616318296
  • artifact 10305635450
  • artifact digest sha256:e0b1e6427f935e801ae41566907580fb0ef58fc7b32642783b61030b70e8fd47
  • status=PASS
  • disposition=SUPPORTED_CONTEXT_FREE_CONSUMER_B_REPRODUCTION
  • failures=[]
  • baseline policy remained hold
  • weak non_deciding => CLEAR mutant killed: true

Runner note: the connector lacked a manual workflow-dispatch mutation, so a separate runner-only branch was used after freeze. It checked out and executed the exact frozen evaluator and candidate SHAs; neither research artifact was modified.

This is bounded research support only. No Contract C version assignment, merge, promotion, release, tag, Authorization, or execution is authorized.
