P7cap batch-face no-stamp ruling: archival record (audit #74 P2)

Date of this record: 2026-11-05. Auditors and the paper supplementary material can verify the no-stamp attestation face of the 21 m7_floor_calibration_p7cap_20261104T093543Z witnesses without access to any controller session; everything below is committed material.

The ruling

controller ruling 2026-11-04 (2) -- batch-bridge no-stamp route,
Phase-D Instrument B

This string is the verbatim committed ruling text carried by bench/m7/tools/attestation_sanctions.py::SANCTIONED_NULL_FACES (key sigminer_post_v3_rust_batch, face null/pre-law, law attestation-lv1). The file’s own header law states that an edit to that table is an edit to the controller’s word, and bench/m7/tests/test_null_face_route.py (group B of the m7 suite) pins the set byte-exactly as its tripwire – so the ruling text cannot silently mutate without reddening the lane.

What the ruling sanctions

The batch-bridge comparison face rides the same null/pre-law face as the frozen 147-row comparison base: witnesses minted on the batch route carry attestation: null plus a null_attestation_face block whose reason must be a KEY of the sanctioned registry (exact key, no prefix, no fuzz). The minter exposes the route through bench/m7/tools/calibrate_p6_floors.py --attestation none-with-reason; the one-witness-one-face law (attestation_sanctions.dual_face_ok) forbids both an lv1 stamp and a null label on one witness, and forbids an orphan null label without the ruling behind it. An unsanctioned replay – same command without the ruling – hard-fails (group B pins this dual-face law with a seen-to-fire refusal control).

Verification recipe (auditor, read-only)

1. python3 -m tests.run_all --only test_null_face_route,test_attestation_law from bench/m7/ – the route law, the registry, the ledger mode declaration, and the seal law all speak green.
2. bench/results/m7_floor_calibration_p7cap_20261104T093543Z/witnesses/*.json: every one of the 21 witnesses carries attestation: null and a null_attestation_face block quoting the ruling string above; tools/matrix_governance.register_p6_anchors verifies each anchor against its witness (the witness is the authority).
3. The witnesses are REP-100, verdict OK, with sidecar cpu/wall seconds matching the anchor table byte-for-byte (pinned by group AC).

Why the route exists

The batch-bridge arm “mints its comparison-base witnesses without the co-tenancy attestation, because the face it rides is the same face as the 147-row comparison base” (group B docstring, verbatim); the registry note adds that “the co-tenancy qualifier arrives with the arm’s own campaign, not this lane” (verbatim). The no-stamp route is the sanctioned way for its witnesses to speak the pre-law face without a stamp this lane cannot lawfully mint. “The ruling converts that from folklore into a data-gated opt-out” (group B docstring, verbatim).
