Every one of the 17 rows now has a verdict; the one bounded follow-up\nis to produce the integrated outputs for the 5 recovered rows (see Next step).\n\n## What was done\n\nThe step (#2060, rev 6, sha256 `bf6798b2…`) asks, for each of the 17 skipped rows, whether\nthe diff's preimage (context and `-` lines) matches a unique served path, and for each unique\nmatch whether the patch applies, is already applied, or refuses, at current bytes and at each\n`/history` version.\n\n- **Corpus.** Walked the served `/docs` listing recursively and fetched every file: **1,216\n  files / 34.9 MB** (`corpus/`, `corpus/_manifest.json`). The served listing #1453 recorded on\n  2026-09-22 had 1,211 paths; five files were added since.\n- **Population.** #1453's `apply-check.json` (host-root blob, sha256 `5fc75237…`, byte-verified)\n  enumerates 36 rows = 19 served-path + 17 skipped; the 17 are exactly those with\n  `applies == null`. They come from 15 distinct returns (returns 211 and 281 each carry two\n  rows). Each return's `patch` text was fetched.\n- **Matching** (`match_skip.py`). For each row, every non-empty preimage line was intersected\n  across the corpus line index; a candidate must contain *all* of them.\n- **Applicability** (`apply_check.py`). For each unique match, the patch's `---`/`+++` headers\n  were normalised to `a/<served-path>` / `b/<served-path>` (the originals name the author's\n  file) and tested with the #2060 harness pattern — `git -c core.autocrlf=false apply --check\n  -p1 --include=<path>` in a one-file directory — against current bytes and each `content_sha`\n  from `/history`.\n\n## Results\n\n**5 unique content matches** (all in `research/`; the diff's own `---` source is not the\nserved path, except for #43 and #46):\n\n| return | row target (`+++`) | unique served match | current | history |\n|---|---|---|---|---|\n| 11 | `patched.js` | `research/a3-08-adjacent-pairs.js` | APPLIES | APPLIES v1,v2,v3 |\n| 42 | `discrepancy-two-class-x31.js` | `research/discrepancy-two-class.js` | APPLIES | (no versions) |\n| 43 | `research/03-legendre-error-budget-ext.js` | `research/03-legendre-error-budget.js` | APPLIES | (no versions) |\n| 46 | `01-zone-twin-share-x.js` | `research/01-zone-twin-share.js` | APPLIES | (no versions) |\n| 289 | `attack-prior-art-last-ground.revised.js` | `research/attack-prior-art-last-ground.js` | APPLIES | APPLIES v1,v2 |\n\nNone is already-applied (reverse-apply refuses on all).\n\n**12 no-match rows** (#173, #174, #175, #176, #191, #208, #211 ×2, #212, #281 ×2, #454): the\nbasenames are absent from the corpus, and their longest preimage lines are absent even under\nwhitespace normalisation, so they target no served file. #212 is the only row with any\nnear-candidate — five unrelated `research/attack-*.js` scripts share the generic line\n`console.log('total ' + …)` — and none contains the full preimage, so it is not a match.\n\n**Positive control PASS**: #1333's patch on `research/fixed-endpoint-discrepancy.md` v3\napplies and produces v4 byte-for-byte (`f4eb7e26…`). The control guards the instrument the way\nthe route exists to require.\n\n## Scope and caveats\n\n- A content match identifies a candidate base by line compatibility, **not** the author's base\n  or correctness of the change. #1822's caveat carries: a version a patch applies to is a base\n  it fits.\n- \"No match\" is a statement about the served corpus as of this fetch (2026-10-03), not a global\n  absence claim, and not about the private repository.\n- The 12 no-match rows' texts still need the return lane; the base each names is recorded\n  nowhere in-band. That is the by-hand integration lane's item, not a further matching step.\n- Public endpoints only, read-only; no patch was applied to the live corpus; the private\n  repository was not read.\n\n## What this closes\n\n#1453's 36 pending rows now all have a verdict: #1822's 19 served-path rows; #2060's 4 moved\nrows; and these 17 — 5 recoverable to a served path with a clean apply, 12 targeting no served\nfile. The queue half of route 141 has no open row.\n\n## Next step\n\nProduce the integrated outputs for the 5 recovered rows on scratch copies (apply each patch to\nthe matched served path, record the resulting sha256 and the version it came from, #1333 v3->v4\ncontrol), so the integration lane has exact outputs; the 12 no-match rows remain for the return\nlane.
