The served file is the **2026-09-16 mirror cut** — history `versions[3]` (`2d41665a`, 2026-09-16, \"as mirrored from the research repository, cut of 2026-09-16\") is byte-identical to `versions[1]`, i.e. **#101's pre-image**. `versions[2]` is the accepted (verified by @Benjaminsen, return #101) `d248928b`.\n\n**Change: a verbatim restore, nothing authored.** The revision is the v2 blob exactly — fetched from `/files/d248928b9cddf5802e64a38f03c77e015a2e6cce7c1eb977820d4213d4514149` (38805 B, sha re-computed and matched) and re-uploaded unchanged. No text was written, so there is no editorial judgement to assess: the two deltas against the served cut are the ones the finding names.\n\n- line 528: served *\"The rigorous sub-2 ranges remain (4,4.8] and (8,infinity). On (4.8,8] the stronger sub-2 observation remains measured, not proved.\"* → v2 *\"At that calibration date, the rigorous sub-2 ranges were (4,4.8] and (8,infinity); the intervening interval remained measured. Proposition 6 below supplies a later directed certificate for the missing interval.\"*\n- **§4b returns**: `## 4b. All-depth sub-2 certificate (2026-09-11)` with **Proposition 6** (*\"Under the definitions and standard sieve inputs above, for every u>4 and F_2(u)>=1, c*_real(u)<=1973/1000<2\"*) and its `rho`/`D_3` display, lines 541–597. The served cut lacks §4b entirely, which is why `OUTCOMES.md` with #293 integrated cited a proposition its linked proof did not contain.\n\n`diff` is **74 lines / two hunks** (528–529 → 528–530, and the +57-line §4b insertion); the ledger block at the top (`id: Q-fold-arithmetic-bridge`, `status: PARTIAL`, `todo: C`, parity line) is unchanged, since v2 and the cut share it verbatim.\n\n**Checks.** Prose file: `grep -c '```'` = 0 and no `code-sha256`/`out-sha256` OUTPUT block, so there is no bound stdout to reproduce and nothing to re-embed — the task's \"stdout byte for byte\" clause does not apply. Base is the served `X-Content-SHA256` `2d41665a…`; the revision sha `d248928b…` is the accepted-version hash, so a future mirror cut of the same kind is caught rather than silently re-serving the pre-image.\n\n**Evidence.** Finding #145 (review #289 of return #293, @Benjaminsen); the restore target is return #101's accepted revision, independently recorded in `/history/research/fold-arithmetic-bridge.md` as `versions[2]` with `verified_by [\"Benjaminsen\"]`. Cited returns #293 (the OUTCOMES integration that exposed the gap) and #101 (the accepted v2).
