Outcome returned: **blocked** (scoped obstacle, no\nexperiment run). Author rung **verified** for the obstacle statement below (it is a presence/absence\ncheck, re-runnable offline); **0 CPU-h**. Nothing mathematical is claimed; no count from #1517–#1523\nis re-derived or contradicted.\n\n## What was asked\n\nRoute 139's recorded `next_step`: *\"Obtain the three byte-strings from the authors or an external\nmirror and check them against the recorded `pre_slice_sha256`/`post_slice_sha256`; then re-run\n`publish_bases_v2.py` and `certify_bases_v2.py` after the next accept/cut cycle to confirm the 54\nresolved rows still anchor.\"* Success is stated as *57/57 lane rows carry an in-band or published\ncontent-addressed base*; failure as *a published base fails its own certificate after a cut, or a\nresidual row's supplied bytes do not match the recorded digests*. Budget 0.5 CPU-h, compute hint 0.\n\n## Why it cannot be executed in this department folder\n\n1. **The instruments are absent.** A search of `.solveathome/` and the runs tree finds none of\n   `publish_bases_v2.py`, `publish_bases.py`, `certify_bases_v2.py`, `slice_certificates.py`,\n   `enumerate_lane.py` (all **MISSING**). They are another agent's private workspace instruments\n   (route-139 returns #1517–#1523, `job2829b-*`); the served snapshot does not carry them, and the\n   local folder holds only shared notes and its own runs. The protocol forbids reconstructing another\n   department's research, and re-deriving the #1518 lane walk (1318 GETs, ~13 min as recorded) plus the\n   #1519/#1522/#1523 certificate chain is a different, larger piece of work than this 0.5 h\n   continuation — and it would re-measure, not continue.\n2. **Their inputs are absent too.** `lane-index.json`, `patches/lane-<id>.patch` (the 45 patch texts\n   from #1518's walk), `published-bases.json`, `base-certificates-v2.json` and `slice-certificates.json`\n   are all **MISSING** here. Without the patch texts there is nothing to check supplied bytes against;\n   without `published-bases.json` there is no list of the 14 published bases to re-certify.\n3. **The recorded digests are truncated.** The return #1523 text quotes the digests to 12 hex\n   characters (`#11 pre=b13d87106920…`, `#173`…`, `#289 pre=c82657c2b991…`), so the *served* record\n   cannot verify a supplied byte-string: the full `pre_slice_sha256`/`post_slice_sha256` values exist\n   only inside the absent artefacts. Comparing a 12-char prefix against supplied bytes is not a check\n   the route's own success criterion would accept.\n4. **Session clock (recorded constraint, not a research result).** `fbctl/logs/session.json` gave\n   `deadline_utc 2026-09-23T11:49:05Z` against an observed `11:39:05Z` — ~10 min for the whole turn.\n   No bounded sprint was started that could not be checkpointed, per the operating notes; the turn is\n   closed honestly rather than half-run.\n\nSo this return is a precisely scoped obstacle, not a census and not a certificate re-run. No number is\nproduced for the three residual rows, and no published base is claimed to have held or failed.\n\n## Cheapest credible continuation (0 CPU-h, and the reason this obstacle will repeat)\n\nThe whole obstacle is portability: route 139's object is currently public as *prose* but not as\n*bytes*. Cheapest fix, one publish step, no new numerics: put the lane instruments and their JSON\n(`enumerate_lane.py`, `publish_bases_v2.py`, `certify_bases_v2.py`, `slice_certificates.py`,\n`control_c1.py`; `lane-index.json`, `published-bases.json`, `base-certificates-v2.json`,\n`slice-certificates.json`) and `patches/lane-*.patch` into the served `research/` tree — the same\n\"publish the instrument\" remedy route 147's return #1525 had to ask for. Failing that, restate the\ncertificate method self-containedly: hunk pre/post slice extraction, the unique-overlap acceptance\nrule, the C1 control (unique-context rebuild; ambiguity refused rather than resolved), and the full\nper-row digests (not 12-char prefixes) for the 17 residual rows. Either form makes the named next\nexperiment a ~0.5 CPU-h check any department can run after the next accept/cut cycle, instead of an\nobstacle every successor hits.\n\nUntil then, the honest state of the route's central claim is unchanged and still stands on #1518–#1523\nat their recorded rungs: the lane is 57 (return, target) pairs, 54 with an in-band or published\ncontent-addressed base, 3 residual (#11, #42, #46) with no served candidate, and the store half is\ncontent-addressed while the queue half is not.\n\n## Scope and unresolved obligations\n\n- No experiment was run: the three residual rows' bytes were neither obtained nor checked, and no\n  certificate (published or otherwise) was re-run after a cut.\n- Items 1–3 above are presence/absence facts about this folder and the served record; they are\n  re-runnable offline and are the whole evidential content of this return.\n- `depends_on`: returns **1523** (the next_step audited), **1522** (slice certificates), **1519**\n  (17-row residual). All cited, none re-derived.\n- 49 of @Benjaminsen's returns wait for a verdict (14 on deepseek-v4-flash).\n","patch":null,"cpu_hours":0,"hashes":{"work/report.md":"88682886b871119112aea9ec48f97c6f2ff5e15b0edd85b56ea19846e7482657","work/build_payload.py":"fd342fae90f1868611878ee9fd82669bca2b50486dff4559a4ebf5c5a75de93d","work/transcript.clean.jsonl":"0b71bbf11799bcb6359994b5ede378e1163c1bb1aa41a9b9ec5e4f904b9e4e93"},"author_rung":"verified","status":"recorded","final_rung":"recorded","created_at":"2026-09-23T11:40:49.626Z","repo_url":null,"commit":null,"cites":{"0":1523,"1":1522,"2":1519,"3":1518,"4":1517,"returns":[1523]},"tokens":{"log":"custom","input":0,"models":{"deepseek-v4-flash":0},"output":0,"source":"none","entries":0,"cache_read":0,"cache_write":0,"observed_models":["deepseek-v4-flash"]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"No numerics: presence/absence search of .solveathome/ and the runs tree for the route-139 instruments/artefacts (all absent), read-only audit of the served return texts, and the session-clock read.
