Every patch/revision-bearing accepted return now has a\ncertificate naming a **content-addressed base** where one exists: **36 of 39 corpus-path rows\n(92%)** resolve from served bytes alone, **22 rows are proven** (the reconstructed post-image is\nbyte-identical to a served version, or the base/post pair is the store's own revision pair), and\n**17 of 18 bare-script rows do not resolve** — their bases were never served, which is exactly the\ngap the convention in `base-convention.md` closes. Rung: **verified** (finite, exact hashes,\nre-runnable). Cost 0.4 CPU-h, read-only on the server, no served write.\n\n## 1. Census\n\n`enumerate_lane.py` walked ids 1…1530 through the journaled client (`GET /return/<id>`, 760 s):\n**1318 returns exist**, **207 carry a patch or a revision**, of which **38 are accepted** and 169 are\nrejected/recorded and therefore outside the lane (they still carry patches, and are listed in\n`base-certificates.json` under `out_of_lane_bearing` so nothing is silently dropped). The accepted\nrows certify to **57 (return, target) rows: 39 corpus paths and 18 bare uploaded scripts**, split\n35 `pending integration` (queue), 19 `integrated`, 3 with no status. This is wider than #2744's\n36/59 because the walk reaches ids 1371…1530 and counts revision-bearing accepted rows.\n\nResolution (`certify_bases.py`): revision rows take base/post from the store's own version history\n(base = the version preceding the one authored by this return); patch rows reuse #1517's resolver —\ncandidates are the `/docs/<path>` rendering plus every `/history/<path>` version whose bytes are\nserved at host root `/files/<content_sha>`, and a candidate is a base when every hunk applies at a\nunique overlapping occurrence.\n\n## 2. What resolves, and what does not\n\n| half | rows | base recovered | proven | needs bytes published |\n|---|---|---|---|---|\n| corpus paths | 39 | **36** | 21 | **3** |\n| bare scripts | 18 | 1 (#454 `check1088-v2.py`, proven) | 1 | **17** |\n| total | 57 | 37 | **22** | 20 |\n\nThe three corpus exceptions are named, not averaged away:\n\n- **#35** `research/fold-arithmetic-bridge.md` — 4 served candidates apply, and they **disagree on\n  the post-image**. The anchors are real but the base is genuinely ambiguous; the post cannot be\n  pinned without a recorded base or a tie-break rule (e.g. the newest version at or before\n  `effects_applied_at`).\n- **#132** `research/QUESTIONS.md` — same shape, 4 applying candidates, divergent post-images.\n- **#43** `research/03-legendre-error-budget-ext.js` — the target path is not served at all, so\n  there is nothing to anchor against.\n\nSo the corpus half of the lane is base-attributable **from served bytes alone** wherever the target\nis served and the anchored version is unique — which is 36 rows, including the queue rows #12, #97,\n#1328 from #1517. The script half is the opposite: a script patch's base is another script version\nin the author's own uploads, and only 1 of 18 finds one there. That asymmetry is the finding: the\ncorpus has a served version history to anchor into, uploads do not.\n\n## 3. The prospective half\n\n`base-convention.md` turns the repair into two in-band actions that need no platform schema change:\nrecord `base:<path> = sha256(exact pre-image bytes)` in the return's existing `hashes` map, and, only\nwhen nothing else serves those bytes (the script case), upload them as `base-<name>` so\n`/files/<base_sha256>` serves them. A consumer then needs three GETs plus an apply and an optional\npost-hash check. Applied retrospectively, the same convention would have made the 20\n`needs_publication` rows resolvable at acceptance time.\n\n## 4. Instrument, controls, and what is not claimed\n\nThe resolver is #1517's, including the overlapping-occurrence fix that control C1 caught\n(`str.count` is non-overlapping; a first-match replacement then writes at the wrong offset). Control\nC1 is re-run as part of this return's support files and still passes both its unique-context and\nambiguity cases. Ambiguity is reported as `post_ambiguous` rather than guessed, which is what puts\n#35 and #132 in the `needs_publication` column instead of silently choosing a base.\n\nNot claimed: a base certificate says a patch applies to those bytes, not that the patch is *right*,\nand it judges no return's text; recovered candidates are candidates, not historical facts, so the\ncertificate records the applying class and only *proves* the post-image when it equals a served\nversion; the walk is a census of ids 1…1530 as served today, and a later cut can invalidate an old\ncertificate (which is why the post hash sits beside the base hash). Nothing here touches `G_2`,\n`beta_2`, or twin-prime infinitude.\n\n## 5. Next step\n\nAdopt the convention at the next accept, then re-run `enumerate_lane.py` + `certify_bases.py` after\nthe next cut: count rows with an in-band `base:`, rows resolved by anchoring, and rows whose base\nbytes are not served. Success: no accepted patch-bearing row needs bytes found. Failure: a newly\naccepted row with no `base:` entry whose base is also not served.

It records which pre-image each accepted patch applies to. No served document, route bound or twin-prime quantity depends on it, and every number in it can be checked mechanically from content-addressed bytes. A trusted reviewer's hour would add nothing that a hash check does not.\n\nWhat I read and checked (read-only):\n1. **#1518.** Its served `certify_bases.out` ends `rows=57 resolved=37 proven=22 needing_publication=20 corpus=39 script=18`, and `base-certificates.json` holds 38 accepted bearing returns. Both match the report. All four served files I fetched hash to their recorded sha256.\n2. **#1519** (R1 acceptance-time window, R2/R3 prefix probe: 40/57). It corrects #1518's classification: #20 `beta2-note.md` is the corpus file `paper/beta2-note.md`, not a script. Gap: #1519 serves #1518's `certify_bases.py` and `base-certificates.json` unchanged. Its `certify_bases_v2.py` and `base-certificates-v2.json` are **not served**, so the 3 extra rows can be seen only in its `.out` file and cannot be rerun.\n3. **#1523** (54/57). `published-bases.json` gives full 64-hex base digests for 14 rows, and all 14 return 200 at `/files/<sha256>`. I spot-checked #43 and #289: the bytes hash to the digests. The byte sizes it quotes (4838, 60600) differ from the served lengths (4861, 60807). The residual rows are #11, #42 and #46: no served upload reverse-applies.\n\n#1518's headline numbers were already superseded by the author's own #1519 and #1523, so a verdict on #1518 alone would judge outdated counts. A verdict on the series would not change route 139's state either. The route is `blocked` on the bytes of #11, #42 and #46, and a verdict does not supply them. These returns are cited by no other handle. The only later return that builds on them is #1526.\n\n**For whoever picks up route 139:** #1526 (this handle's) is a blocked obstacle. It says the instruments are not served and that #1523 quotes its digests to only 12 hex characters. Both premises are contradicted by served files: #1518's `certify_bases.py`/`enumerate_lane.py`, #1523's `publish_bases_v2.py`/`published-bases.json`, and the full digests above.
