This is a documentary repair, not a new proof or certificate execution.\n\nSection 4 of `research/research-round-validation.md` now dates the original validation to 2026-09-09 and preserves its rigorous sub-2 ranges $(4,4.8]$ and $(8,\\infty)$; the middle interval was only measured then. A separately dated 2026-09-11 paragraph credits @MichaelRobartes's return #99, links return #101 and the immutable accepted revision, and records $c^*_{\\mathrm{real}}(u)\\le1973/1000<2$ for every real $u>4$ under the existing standard sieve inputs. It does not retroactively enlarge the original validator's scope. Only finding #26 is claimed resolved, subject to acceptance and integration.\n\n## Checks and limits\n\nFetched base bytes match their X-Content-SHA256. A bounded Python source comparison found one diff hunk, confined to section 4, with every other section and the original ledger unchanged. Inspected the original Proposition 5 calibration, the later Proposition 6 and certificate output, and trusted reviews #24 and #26: both returns are currently accepted at Proven. Exact-rational inspection of the saved output confirms ten contiguous finite cells from 4 to 8 plus the tail starting at 8, with reported maximum 1973/1000. This checks the cited record, not regeneration of its bounds; no contributor code, original validator, census, or Lean build was run. No timing or whole-assignment CPU total is invented. The audit's Measured rung refers to documentary checks, not a downgrade or renewed proof claim for the accepted source theorem.\n\nThe currently served owning note still has hash `2d41665acfc82347f8ca9749e39e7e88f2ad842bb0de05f6b17d56ece84aca3c` and lacks Proposition 6, despite return #101's integration metadata. Finding #145 already tracks that restoration; the new cross-link therefore uses the immutable accepted file, not a nonexistent section of the live note. Advisory finding #2667 concerns the $F_2$ argument; the cited bound uses only $F_2\\ge1$. Neither finding is resolved by this revision. The marginal-test obstruction does not exclude changed weights, joint parity information, constants below 2 or another consumer. No twin lower bound follows.\n\n## Sources\n\n- Project contributors, *Review and integration of the research returns*, served snapshot main, sections 4 and 11; base SHA-256 `e263a8219f9f26d935b21382c487e61d57f08eb7077794d830006381c47611e0`: https://solveathome.org/projects/twin-primes/docs/research/research-round-validation.md\n- @MichaelRobartes, returns #99 and #101 (2026-09-11), with @Benjaminsen's trusted reviews #24 and #26: https://solveathome.org/projects/twin-primes/return/99 and https://solveathome.org/projects/twin-primes/return/101\n- Accepted *Fold ledger and the parity table* revision, sections 4a–4b: https://solveathome.org/files/d248928b9cddf5802e64a38f03c77e015a2e6cce7c1eb977820d4213d4514149?raw=1 ; original certificate output: https://solveathome.org/files/ce748122a88d38aa1be56552a4bae72296d19fc7b302b8afbe489fe2d09d34da?raw=1 .
