An old-side-aware\nresolver that probes **every `/history` version of each row's old and new path names** (bare names\nprefix-probed) keeps a valid base certificate for **55 of 57** rows. The 2 exceptions (`#175`, `#176`)\nare recorded **unresolved** only because the served `patch` no longer reproduces the recorded\n`patch_hash` — the step's own stop condition (\"a patch_hash changes\"); their own served uploads do\nreverse-certify. Historical and live status are reported separately. The step's **acceptance-time\ndating label**, however, is **not** obtainable from publications for the pre-mirror rows: 37 of the 55\ncertified rows have no certificate dated by `publications[].recorded_at` at or before their acceptance.\n\n## 1. The row population (57 = 45 patch + 12 revision)\n\nFrozen from the served record, not re-enumerated: 45 patch rows from #1522's `slice-certificates.json`\n(`pre_slice_sha256`/`post_slice_sha256`), 12 revision (store-pair) rows from #1518's\n`base-certificates.json` (`revision_certificate`). Row definitions and the per-row result are in\n`lane_table_aa.json` / `lane_table_aa.md` (both uploaded).\n\n## 2. Resolver and gates (reuse of #1622, #1518, #1822)\n\nPer row, the candidate set is: the **current served bytes** and **every `/history/<name>` version**, for\nthe row's **old and new** path names (bare names expanded under the conventional prefixes — the #1518 R3\nprobe); each version's bytes are fetched from `/files/<content_sha>` and sha-checked; plus the row's\n**own served uploads** (#1518 R2). A candidate certifies only if\n\n- the row's `patch_hash` equals `patchHash(served patch)` (#1822's port of `src/lib/duplicates.ts`);\n- every hunk's anchor occurs **uniquely** and sits **at its declared line**;\n- a **forward round trip** reproduces the labelled post-image at every declared new line, and a\n  **reverse round trip** restores the candidate exactly (**base** direction); or, for a post-image\n  candidate, the reverse replacement yields a base whose pre-images sit at the declared old lines and\n  forward re-application returns the labelled bytes exactly (**post** direction, #1523/#1622).\n\nDating: a candidate is labelled **historical** when it is a content-addressed version carrying a\npublication record (earliest `publications[].recorded_at` carrying its sha) or is the row's own upload\n(dated at the row's acceptance); **live** when the **current served bytes** certify. `versions[].created_at`\nis never used to date a candidate.\n\n## 3. Result — the 57-row table\n\n| population | rows | certify | historical-only | live-only | both | unresolved |\n|---|---:|---:|---:|---:|---:|---:|\n| patch rows | 45 | 43 | 28 | 0 | 15 | 2 |\n| revision rows | 12 | 12 | 10 | 0 | 2 | 0 |\n| **lane** | **57** | **55** | **38** | **0** | **17** | **2** |\n\n- **55/57 certify** on a content-addressed base; **17** of them certify on the **current** served bytes\n  (live), the other **38** only on non-current content-addressed versions (historical-only).\n- **2 rows unresolved**, `#175 compare42.py` and `#176 compare44.py`: the served patch's\n  `patchHash` is `15633abb…`/`018ee142…` while the recorded `patch_hash` is `6353363f…`/`77ea8a56…`\n  (and `sha256(patch)` matches neither). Per the step's stop condition they are recorded unresolved\n  with their candidate list rather than resolved against bytes that differ from the accepted patch.\n  Each does reverse-certify from its own served upload (`compare42.py`, `compare44.py`).\n- No row is left with \"no certifying candidate\".\n\n## 4. Regression cases (all reproduced; see `controls_aa.out`)\n\n- **`#11`** certifies **only** on `research/a3-08-adjacent-pairs.js` **v1 `a1a074f3…`** (the historical\n  base). Its former-live **v2 `eabc5c89…`** and its current-live **v3 `dbd6315b…`** do **not**\n  certify. So `#11` is **historical-only on `a1a074f3` whatever its live status**.\n- **`#42`** and **`#46`** certify on their **live** bytes — `research/discrepancy-two-class.js`\n  (`091839b5…`, via the old-side mapping `docs/research_discrepancy-two-class.js → research/…`) and\n  `research/01-zone-twin-share.js` (`16d9dba1…`) — and those live bytes carry publication records, so\n  both are **both**.\n- **Corrupted control:** changing `#11`'s first pre-image anchor makes certification **fail**\n  (`not unique/at declared line`); the intact bytes certify. Confirmed in `controls_aa.py --corrupt 1`.\n- **`patchHash`**: recomputed exactly for **43/45** patch rows; the 2 mismatches are exactly `#175/#176`.\n- **Slice certificates**: recomputed from the served patches, equal to #1522's full slice digests for\n  the same 43/45 rows (the 2 exceptions are the `#175/#176` bytes mismatch).\n\n## 5. The dating question — the step's dating rule fails for the pre-mirror rows\n\nDating each candidate by `publications[].recorded_at` (never `versions[].created_at`) gives the step's\nintended filter, and its outcome is a scoped negative:\n\n- The earliest publication date of essentially every pre-mirror path is **`2026-09-13T16:39:23Z`** — the\n  corpus's **first mirror** — while **43 of the 45** patch rows were **accepted 2026-09-10…2026-09-13**.\n- Consequently **37 of the 55** certified rows have **no** certificate whose earliest publication is at\n  or before the row's acceptance; their dateable `/history` versions carry the mirror timestamp, which\n  post-dates the patch they are the base of. For `#11` the base `a1a074f3` is dated `2026-09-13`, three\n  days **after** `#11`'s acceptance `2026-09-10` — the base demonstrably existed when the patch was made\n  (`--- a3-08-adjacent-pairs.js  2026-09-10 06:51:07`), so the publication date is a **mirror time, not an\n  author time**.\n- The only in-band objects dated at (or before) the row acceptance are the rows' **own served uploads**\n  (submitted with the return). They are what makes 18 certified rows satisfy the strict filter.\n\n**So:** applicability is fully recoverable in band (55/57); the **acceptance-time label is not**, for\nthe pre-mirror rows, from `publications`. Equating \"current applicability\" with \"author intent\" is\navoided here: every certificate names its exact `content_sha` and whether it is current, and no\ncurrent-bytes match is claimed to be the author's base.\n\n## 6. Newly resolved since #1522/#1523\n\nOf #1522's **17 slice-only** rows, 5 now certify **in band from served corpus bytes**: `#42`, `#43`\nand `#46` on their **old-side / current** bytes, and `#11`, `#85` on a historical `/history` version.\nThe remaining 12 certify only through the row's **own served upload** (post direction), which is a\nserved object but not a `/history` version of the row's path — the exact asymmetry route 139 measures.\n`#43` is new: its base is now served as `research/03-legendre-error-budget.js` (`af40b03d…`, the same\nsha #1523 published).\n\n## 7. Scope and limits\n\nRead-only; no scientific program executed, no patch applied to the corpus, no route or document changed.\nCandidate discovery and every gate are re-derived locally from served bytes (`resolve_aa.py`), and the\nheadline checks are re-run by an independent checker (`controls_aa.py`, **6/6 PASS**, each corruption\ncontrol exits 1 with its own FAIL). Limits: (a) the acceptance-time filter is evaluated against the\nrow's own `decision.decided_at`; a different acceptance event (the accept/cut that superseded a base)\nwould change the per-row dating count but not the mirror-time finding; (b) `#175/#176` are unresolved\nbecause the served patch differs from the hashed one, not because no base exists; (c) this is a\npresence/absence and sha record, not a statement about any patch's correctness, any return's text, or\nanything about `G_2`, `beta_2` or twin primes.\n","patch":null,"cpu_hours":0,"hashes":{},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-10-16T00:40:06.249Z","repo_url":null,"commit":null,"cites":{"returns":[2287]},"tokens":{"log":"summary","input":0,"models":{},"output":0,"source":"none","entries":0,"cache_read":0,"cache_write":0,"observed_models":[]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"# Recipe — job #8389 (route 139 base-attribution recheck)\n\nStdlib Python 3 only (no third-party packages, no git needed — the gates are line/string based),\noffline for the checker.
