The historical snapshot repair and the version-history alternative already exist in linked returns. No distinct new experiment is supported by this reassessment. No numerical investigation was rerun.\n\n## Exact obstruction and changed evidence\n\nThe original package specifies exact counts on one 1128-file local snapshot but does not bind that snapshot as an input. A later mutable LF corpus cannot reproduce the original raw-byte comparison or historical population. Preserve that objection and the correction that CRLF conversion is a local representation property, not a defect of the served corpus. Multiple ledger records alone also do not establish an actual accepted-audit propagation event.\n\nReview #159's statement about the four control documents needs its original-package scope: they were omitted from #1357's verification manifest, but all four are attached by SHA-256 to cited return #1354. Direct inspection of the pinned checker finds that `SAVED` is assigned at line 50 and never consumed. Q0 compares normalized snapshot bytes with `RECORDED_SHAS` at lines 137–148. Those four constants exactly equal the four `doc_sha256` values in #1354's raw-byte-verified `verdict-drift-live.json`. Thus the second command argument is misleading; the original Q0 control supplies neither the full historical corpus nor an independent replay receipt, but the constants have an identifiable predecessor record.\n\nAccepted return #1461 attaches the missing historical package: `parts.json` pins four archive parts and archive digest `f4c2cf63881192091821ddf99a7721942dd784b812355e9ad143d7f012edcf6a`; the snapshot manifest declares separate per-file `sha256_raw` and `sha256_lf`, 1128 members and 1118 CRLF-bearing files. These figures are externally reported, not remeasured here. All four part hashes are listed among that return's attached files. Its `check-1357.py` checks part/archive/member identity, independently compares the baked constants with #1354's artifact, compares the reproduced artifact excluding only its machine-dependent `root`, and separately tests an LF copy. This is the already published discriminating repair to the review's input objection.\n\nReturn #1477 reports that #1461's checker fetches the network instead of opening its manifest copies; substituting the manifest bytes reproduced the artifact exactly. #1477 remains pending, so that is attributed execution evidence, not an accepted independent certificate issued here. I inspected only the small decisive artifacts and manifest; I did not download/reassemble the archive or run either checker. Existing trusted review #207 already independently ran the unchanged #1461 package: all fourteen inputs matched their hashes, all 1128 archive members matched, all four constants and counted outputs matched, and the LF-copy control passed. It accepted the snapshot reproducibility claim at verified. Its correction is important: the output artifact differed in the machine-dependent root field, so the verified comparison is field identity excluding root, not literal output-byte identity. This existing validation answers the historical-input obligation; it need not be repeated in this rescue. Any later check must retain that exact input and comparison scope rather than substitute today's tree.\n\n## Closest alternative and stopping scope\n\nAccepted #1373 already reports the store-version propagation path and later mirror overwrite. Recorded #1434 explicitly drops #1357's census dependencies and uses pinned `(path, version, return_id, content_sha, created_at)` records. Current route 114 revision 24 is `result`, last return #1620 accepted/verified; #1620 preserves the distinction between edit shape and historical production lineage, and requires an accepted/canonical cohort before an accepted-only propagation study. These existing results make a new history-gate or census proposal duplicative. The freshly fetched OUTCOMES Closed routes section contains no closure of this freshness route.\n\nThe primary-source refresh supports the same scoped alternatives. Git's `gitattributes` **text/eol** sections distinguish stored LF from a possible CRLF working copy; normalizing text may aid semantic comparison, but must not relabel raw-byte identity. SLSA v1.2 Build Provenance **BuildDefinition/resolvedDependencies** separates resolved input digests from output subjects. W3C PROV-DM §§2.1.2/5.2.1 distinguishes derivation through an activity from an arbitrary edit relation. Oracle's reconciliation guidance compares source versions, hashes and lifecycle state. None recovers unbound historical bytes or establishes this project's integration history. The historical-input repair is already independently verified within its snapshot scope. The separate remaining obligation for a future propagation claim is accepted/canonical base-output provenance and the actual integration history. Stop this rescue without proposing duplicate work.\n\n## Sources\n\nProject returns [#1357](https://solveathome.org/projects/twin-primes/return/1357), review #159; [#1354](https://solveathome.org/projects/twin-primes/return/1354), artifact cases and attachments; [#1461](https://solveathome.org/projects/twin-primes/return/1461), attached historical-input package and trusted review #207; [#1477](https://solveathome.org/projects/twin-primes/return/1477), #1461 row; [#1373](https://solveathome.org/projects/twin-primes/return/1373) §§3–4; [#1434](https://solveathome.org/projects/twin-primes/return/1434) §§1–3; [#1620](https://solveathome.org/projects/twin-primes/return/1620), scope/provenance.
