R12 ER Factorized Witness-Route Result
Protocol: r12_er_factorized_witness_route_train_only_canary_v1
Decision: reject_factorized_witness_before_fresh_board
The route is closed. It must not receive a fresh board, threshold relaxation, or post-hoc optimizer tuning.
Operational provenance and custody receipts
The job/node/runtime, beacon derivation, and Newton mirror statements below are operational journal receipts. They are not independently reconstructed by the three-file artifact audit.

|---|---|---|---|---|---|
| Treatment | 2,069/8,000 = 25.8625% | 2,239/8,000 = 27.9875% / 2,209/8,000 = 27.6125% | 57.8875% | 77.075% | 99.9875% |
| Same-seed baseline | 11.7125% | 12.9625% / 12.8875% | 37.975% | 59.050% | 93.0125% |

Treatment joint accuracy collapses with cardinality: 67.276% at N=3,
35.501% at N=4, 5.550% at N=5, and 1.892% at N=6. Treatment has
99.1375% initial rows/pointers and 99.9875% line pointers, so the failure is
localized to witness identity transport and the relation assembled from it.
Nine of thirteen frozen gates pass. The failures are the absolute witness, relation, packet/state/answer/joint, and minimum-cardinality joint gates. Exact alpha invariance, source-only oracle transport, matched initialization, parameter accounting, train-only custody, and treatment gains over baseline and shuffled controls all pass. Partial relative gains cannot override the absolute failure.
Independent artifact-only audit
train/audit_er_factorized_witness_route.py verifies the three exact artifact
hashes, all 33 committed source files, source/seed receipts, all arm
initialization/fit/frozen-parent receipts, the exact 400-leaf metric schema and
its cardinality/depth/renderer aggregates, evidence shapes, and every frozen
gate without reading any ER-TT board row or scored split. It independently
recomputes every retained canonical-versus-recoded alpha field and the complete
mask as 8,000/8,000. The serialized canonical audit JSON including its trailing
newline has SHA-256
272b6b3be28fab3741c6e5c383a1c02b37d7b7e8b394dd6424d41f12de9bbe3d;
its explicitly labeled preimage self-hash is
3747beac310a790791d02677a050aa2e370d0a4b6153b999cd89d4a013e8a6ca.
The read-only report is stored at
artifacts/r12/er_factorized_witness_route_artifact_audit.json.
The effective cardinality-dependent 1 + 2N address slice with side-major
roles selects the grammar-correct one-based ordinal on 36/36 active cases in
treatment and structural-only, 10/36 in shuffled-address, and 0/36 in baseline
because its gate is exactly zero. Treatment gate/table L2 norms are
0.7896/3.5995; structural-only norms are 0.8211/4.2015. Thus the table learned
the deterministic grammar address, but the soft content residual did not carry
a coherent symbol identity through that address. Structural-only can point to
the right slot while producing only 1.25% exact relations, demonstrating that
address correctness is not content transport.
Control row-level predictions were not retained, so paired McNemar statistics cannot be reconstructed. No second probe access is permitted to repair that omission. Oracle-route targets were also not retained, so its 8,000/8,000 exactness remains an internally consistent producer receipt rather than an independently regenerated result. Family disjointness, custody counters, frozen-parent integrity, and total compiler/base parameter counts are likewise hash-bound producer receipts. Treatment trainable parameters and all alpha comparisons are independently recomputed from retained tensors.
Consequence
The factorized lookup is a structural answer key for this grammar, not a native reasoning mechanism. It is also seed/optimization-sensitive: its same-seed baseline witness score is 11.7125%, far below the historical marginal v1.1 endpoint of 89.925%. Both facts make threshold tuning scientifically invalid.
The next architecture must make the committed content state itself causal and reusable. Closure-Tied Action Algebra (CTAA) is the current pre-neural falsifier: a trunk-conditioned hard categorical state transducer whose action application and action composition share parameters. Its CPU mechanics are audited independently; no neural source, seed, board, or H100 job is yet authorized.
