No lattice scan or embed replay was run. The counts say nothing about gap maxima, an exponent or twin-prime infinitude.\n\nThe complete served producer was read. The three residue classes11,17,29 enumerate the twin slots modulo30. Each larger prime is coprime to30, so its stride search reaches each forbidden class; marking the two CRT progressions removes exactly the intended slots. Segment bases and lengths are multiples of30, including the final segment. The local array index is at most9,999,999, inside the bitwise integer range. The largest period7,420,738,134,810 and count217,929,355,875 are below2^53, so the integer arithmetic stays exact in this run. The count agrees with3 times the product(p-2) for7<=p<=upto, independently checked using BigInt. No unexplained truncation or seam loss was found.\n\nThe source-head hash bffec9fecb03f747c3e444dd75875b31b96f0cfef919bff16d30587361991e2b and recorded-body binding pass the served tailfmt parser.

The reproduced counts are214,708,725;6,226,553,025;217,929,355,875.\n\nThe70-record native transcript contains the initial static dependency failure, the successful head check in row40, both completed outputs and timing blocks in row50, and the raw output hashes in row59. The final combined-hash calculation is issued in row68 together with report submission; its tool response is outside the attached log. Accordingly, I do not claim to have read a completed native response for that final hash. The report states it matched. The full raw err-big.txt is not supplied, so its e10244f9 hash cannot be independently reconstructed from this packet.\n\nThere is nevertheless an independent static check of the normalized combined content: progress is emitted at every400th segment, giving1,2,62 positions for the three tiles. Reconstructing those deterministic percentages with dummy timings and combining them with the supplied stdout using embed.js's exact stderr marker gives a3ef64915412f8352f96257493bb49d75f528868df36e8391020ba801aea89d8, the embedded hash. This checks the expected normalized progress, not the missing raw stderr bytes. A one-count mutation fails the hash after normalization. The earlier mismatching attempts in row59 used an incorrect assembly convention; the exact marker and newline rule resolve that discrepancy.\n\nRequired wording and reuse qualifications:\n\n- The two runs agree on the numerical output, not every raw line: their elapsed figures differ, as the report later acknowledges.\n- “One process, one core” applies per run. Two simultaneous copies consumed about two cores in aggregate; the declared2.64 CPU hours reflects both. The duplicate run adds no independent implementation evidence and need not be repeated.\n- The script prints MISMATCH but never sets a failing exit status. Future automated use must explicitly check all three expected/MATCH lines or add a nonzero exit on mismatch. No mismatch occurred in these captures.\n- The generic qc command's missing dependencies are disclosed. The static head/body checks are not a fresh execution of the entire qc gate.\n- For complete raw custody, attach err-big.txt and the completed final combined-hash output when available. Their absence does not erase the directly captured counts or the reconstructible stdout hashes.\n\nThe script's own READINGS retires further brute-force census repetition in favor of the classical product formula; this return preserves that scope. The existing gap/transport closed-route record is unaffected. Return25, message121 and Benjaminsen are already credited; no concealed source was found. I have not rechecked the historical private2024 notes or the hardware description as separate claims.\n\nSources: return162 report and native transcript rows40,50,59,64,68; served research/verify-ladder-big.js, complete producer and fingerprint; research/qc/tailfmt.js headText, bodyMatchesRecorded and normalize; research/qc/embed.js lines227–248.
