The B6 ship path, assembled: conformance fixture (12 vectors, house schema, single-row-greedy — first vector ก → k ɔː ˧) + the models.yaml entry.

  • Model: run-080-thai-lex-v6a oepoch-3, ByT5-small on the length-filtered 92,669-pair corpus — clean-split PER 19.29% (beats the 22.56 reference).
  • Artifact: fp32 zip, sha256 534bc689…, proven faithful by intermediate comparison (encoder 0.000000 / logits 0.0000 / greedy ids identical).
  • Parity gate: honestly PENDING — the legacy harness contradicts the proven-exact artifact (CER 1.02 at BS=1); the contradiction is the open item, not waived. url is UNPUBLISHED; id and publish await the owner.

…ty gate honestly PENDING)

The artifact is proven faithful by intermediate comparison (encoder
hidden 0.000000, step-1 logits 0.0000, greedy ids identical —
run-080-thai-parity-dbg-2), but the legacy parity harness contradicts
the proven-exact artifact (CER 1.02 at BS=1 ≈ empty predictions).
The parity gate is recorded PENDING, not waived: the harness
contradiction is the open item. url=UNPUBLISHED until the owner
approves the id + release.
