The run commits 89c0ed9d and 430f8883 are kept as they are, and this branch adds one commit, 24670483, holding the first floor. The merge keeps all of them.

The result

B2 fails.

• earn_zero_rate.prime's full-support gap is 0.3034, against a tolerance of 0.202.
• No gate seed passes.
• Three of the four gated bounds exceed their tolerances.

Under design §7 (GATE_FAIL_OR_REGRESSION_FAIL), B2 is not admitted, and H and B3L cannot rely on it. There is no rerun, seed selection or tolerance relief. The per-cell results are in #42 comment 6252752628. Max is asked about the earnings lane's next step as d1659.

Blindness. These files hold 2012 and 2014 floor values, truth moments and candidate outcomes. Blind review roots built from master after this merge must exclude them.

Attempt ledger. The cumulative attempt ledger entry is a separate PR, so that this one adds only the run's files, as registered.

axiom: n/a (gate run record, no policy encoding)

Merged at head 24670483 as merge commit 11d514a3 (2026-10-18 18:24Z).

Gates: gh pr checks exited 0 on the latest run, and the PR was MERGEABLE and not a draft, with no changes requested.

Review (job 20261018-131505-trackb-b2-results-prs-r1, Astra): APPROVE.

• It found the diff adds exactly the four registered files, and that every SHA-256 matches Candidate 2 design: latent-permanent conditioned chained QRF (research memo) #42 comments 6252422772 and 6252752628.
• It found runs/track_b_b2_floor_v1_stopped.json byte-identical to the floor at 7fdc8f91.
• It found the run commits 89c0ed9d and 430f8883 unchanged.
• It found the score complete under the registration's step 5.
• It ran 205 targeted tests, all passing.

Disclosure. One of the reviewer's delegated searches used shell-expanded tests/test_*.py operands. Those overrode its exclusion glob and read tests/test_m6_* sources, against its prompt's rule. The reviewer is not an operator, and B2 was already scored, so no B2 result depends on it.

This lands B2's run record on master, per the rescoped registration's step 5 (#42 comment 6252388925).
