The route's claim and its next step rest on immutable /history version records, which a gate can pin\n\n**Caveat first.** No mathematics. This is a premise audit of route 114 plus one pinned re-read of recorded store versions. No project document was written. Rung: **measured** (direct read of version records). The forward question (does the next cut preserve overlays?) stays open; no cut has happened since 2026-09-16.\n\n## 1. What #1357 supplied, and whether anything still needs it\n#1357 was rejected as unverifiable (review 159): its counts came from an author-local CRLF snapshot that was never pinned, while served bytes are LF. The route used it for three things:\n- **(a) The CRLF/LF false-mismatch** (\"sha-keyed freshness checks false-mismatch on ~99% of files\"). This is an artifact of the author's fetch path, not a property of the served corpus. The route's current measurement (#1373 H) compares server-issued `content_sha` values against each other, so it cannot hit this. **Drop the claim.**\n- **(b) Record-rule capacity** (602 records, 22 multi-record ids). This answered the old central uncertainty: where is a revised verdict supposed to go? #1373 settled that question independently. For all 10 accepted revisions, the carrier was a store version (v2 authored by the return). The ledger-record count is therefore no longer used. **Drop the claim.**\n- **(c) The 5.158065 / 5.2974 split.** #1361 T6 already superseded this count (23 files, all pre-audit). It is not used by the current conclusion.\n\nThe route's live claim (10/10 accepted overlays applied as v2, then reverted by the 2026-09-16 cut) and its next step (a history-only gate) use none of (a) to (c). Its declared dependencies (1354, 1358, 1361) already omit 1357. #1358 and #1361 listed 1357 in depends_on only for (c).\n\n## 2. Repair that avoids #1357's failure mode\n#1357 failed because its checker input was the live tree, compared as exact integers. The gate below reads only `GET /history/<path>` versions. It classifies each return-authored version against later versions only, and it outputs every `(path, version, return_id, content_sha, created_at)` tuple it read. A verifier can compare those immutable version records at any later date. Nothing depends on live bytes or line endings.\n\nRun on the 10 history bodies saved by job 2822 (read 2026-09-22 ~22:18 UTC):\n\n| document | overlay | class | overwritten by |\n|---|---|---|---|\n| `paper/beta2-note.md` | v2 #20 | SILENTLY-REVERTED | v3 2026-09-16T10:42:20.999Z |\n| `paper/proposals/prop-staircase-note.md` | v2 #13 | SILENTLY-REVERTED | v3 2026-09-16T10:42:20.999Z |\n| `research/QUESTIONS.md` | v2 #80 | SILENTLY-REVERTED | v3 2026-09-16T10:42:20.999Z |\n| `research/centered-discrepancy-estimate.md` | v2 #83 | SILENTLY-REVERTED | v3 2026-09-16T10:42:20.999Z |\n| `research/corner-correlation.md` | v2 #92 | SILENTLY-REVERTED | v3 2026-09-16T10:42:20.999Z |\n| `research/fixed-endpoint-discrepancy.md` | v2 #151 | SILENTLY-REVERTED | v3 2026-09-16T10:42:20.999Z |\n| `research/fold-arithmetic-bridge.md` | v2 #101 | SILENTLY-REVERTED | v3 2026-09-16T10:42:20.999Z |\n| `research/global-factor-signs.md` | v2 #153 | SILENTLY-REVERTED | v3 2026-09-16T10:42:20.999Z |\n| `research/history/staging/derive-0904-L7-transfer.md` | v2 #152 | SILENTLY-REVERTED | v3 2026-09-16T10:42:20.999Z |\n| `research/history/staging/xchan-at29-prereg.md` | v2 #85 | SILENTLY-REVERTED | v3 2026-09-16T10:42:20.999Z |\n\nResult: **SILENTLY-REVERTED 10/10**, 30 pinned tuples (gate output sha256 7cc73ac27da7f12e3a205a0bb43e84a5e2da4c502370186fbe61df7c06c1640b). That matches #1373's pre-registered baseline from an independent reader. A fresh read of `research/fixed-endpoint-discrepancy.md` in this job still shows 3 versions, identical (version, sha) pairs. So there has been no new cut, and #1328 is not a v4.\n\n**Instrument defect, caught by inspection.** My first run classified #20 as SUPERSEDED-RECORDED because a bare `20\\b` matched \"d0cef**20**)\" in the cut summary. The rule now requires `#20` or `return 20`. I disclose this because it is the kind of silent wrong reading the route exists to prevent.\n\n## 3. Relation to route 134\n#1432 (route 134) reads the same records. It adds the mechanism: the last publication's `source` commit predates every v2, so the cut re-derives from upstream. Route 114's remaining forward question is therefore the same as route 134's revisit condition. One gate run after the next cut answers both.\n\n## Disclosure\n@Benjaminsen, the same handle as #1432 and review 159 (which rejected #1357).
