R12 Post-Commit Packet Transport V3 Result

Decision: PROTOCOL PASS FOR EXACT PACKET TRANSPORT; NO LEARNED-REASONING CLAIM. Scientific commit 36906818f17aa4f03b9f5622dbcb65110ae95abf completed the canonical v3 command. The independently implemented verifier reconstructed the complete evidence twice, required the committed scientific sources through Git, and alone published the read-only artifact and receipt.

Canonical command:

python3 pipeline/post_commit_packet_transport_falsifier.py run \
  --out artifacts/r12/post_commit_packet_transport_v3.json

The receipt payload SHA-256 is 41eba8d49b8c06e0f93a0b84d9fbc54f293052660c56bf7f61fa3d3deb638a01. The independently committed verifier source SHA-256 is 0eacabce52cf8bbe14ca5b73120ad37cc227ac814c12cc73ea66d3f8e2c23478. A fresh post-publication invocation of verify-publication, with Git verification required, also exited successfully.

Final Independent Audit

A fresh read-only adversarial audit of committed publication commit 61c627f returned GO. It verified HEAD == origin/main, checked every reviewed file against its Git blob, reran all 38 focused tests, reran verify-publication with Git verification required, reconstructed the role counts and score arithmetic, and confirmed the artifact/receipt hashes and local 0444 modes. The auditor also forged a score in both replay cores and recomputed every affected self-hash; independent semantic reconstruction rejected that self-consistent forgery.

The audit records two non-blocking limitations. Git stores the blobs as 100644, so a fresh clone does not preserve the local publication mode, and neither historical execution nor entropy provenance is cryptographically attested. Both are outside the frozen claim. Final authorization is GO for a separately preregistered learned architecture experiment and NO-GO for describing PCPT v3 as learned reasoning, novelty evidence, or tamper-proof attestation.

What Passed

The protocol demonstrates an exact finite mechanism that writes a four-symbol packet, updates it through isolated one-event processes, deletes privileged source access, and answers late queries from the terminal packet. The packet transport remains exact while a deliberately insufficient motor control and a depth-eight transport cap fail at the preregistered boundaries. The parent cannot publish canonical evidence; the independent implementation reconstructs all role byte streams, affine chains, scores, challenge binding, sandbox evidence, and deterministic replay before publication.

Claim Boundary

This is a pass for exact symbolic packet transport and evidence custody. It does not show that a neural network can learn the packet, choose its own operations, halt, generalize in language, or reason. It is not a claim of a novel memory primitive, historical tamper-proof attestation, or SoTA capability. The finite affine board has a known sufficient coordinate basis and therefore serves as a mechanism/control gate, not as novelty evidence.

The pass authorizes only a separately preregistered learned architecture lane. That lane must distinguish durable state learning from autonomous control, include equal-budget favorable controls, delete source/KV access, test unseen queries and recodings, and require fresh researcher-written interactions. It may not alter the immutable 300k checkpoint or claim reasoning from fit loss.

Defect History

Three precommit adversarial rounds closed default-allow filesystem escapes, nonce timing and caller-control defects, self-published receipts, incomplete independent reconstruction, and claim-boundary drift. The first commit-bound run from 5903fbf then failed closed before publication because a relative artifact path was passed to a verifier launched from a fresh cwd. Commit 3690681 resolves publication paths before process launch and adds defect-21 regression coverage. The complete suite remained 38/38 passing before the successful canonical run.
