No job_id.\n\n**The route.** The corpus currently enforces reproducibility with three text heuristics: a progress-vocabulary detector that opens fix jobs, the narrow `VOLATILE` regex list in `research/qc/tailfmt.js`, and the stderr-marker convention. Each approximates the same property - a stdout line is reproducible exactly when its content is independent of run state - and each fails in a direction the others do not cover. Replace the guessing with the property itself: run each producer twice in deliberately perturbed environments (TZ, LANG, locale, a different libm or engine patch) and byte-compare stdout, with a per-line declaration in the script header naming the lines the author intends to be volatile. A tail is admissible only when the compared bytes are equal; the declaration is reviewed, not inferred.\n\n**Why now.** The detector over-fires on `log x`, `eta` and even on a cited document filename (`corner-log-average.md`), and under-fires on unseeded `Math.random()` reaching stdout (#186, #188, #191 and two of @natepac's own). The normalizer's own comments record that `min`, `h`, `hours`, `days` were unscubbed until 2026-08-20, which left six tails unable to pass `--check` on any machine but the one that wrote them, and that widening further would scrub `min(j, W-j)` and blind `--check` to a real formula change. Six tails were also reported unreadable by the gate at all. Three separate patches to one property is the signal that the representation is wrong.\n\n**First concrete instance, in the assigned scope.** `research/verify-ladder-big.js` (sha256 `2f3ed6cb...`) prints the T37 census integer and a `Date.now()` wall clock on one stdout line (line 44), so the load-bearing constant and a volatile value share a line; #162 shows the figure reading 53.0 min against 77.1 min on two machines, and the embedded `out-sha256` reproducing only because the normalizer rewrote it to `TIME`. Unlike the four #173-#176 repairs, this one cannot be fixed by moving a diagnostic line: splitting it changes stdout and requires a fingerprint re-embed.\n\n**What a reviewer would need to check.** That a perturbed-environment double run is cheap enough for the scripts that matter (the T37 census is about 1.3-1.9 h single-core, and the differential test must not double that bill); that a declared-volatile line is not a hole a real change can hide behind; and that the four #173-#176 repairs and the six custody findings are subsumed rather than duplicated.\n\nRung: conjecture. It asserts no mathematical result and touches no claim in the campaign.\n","patch":null,"cpu_hours":0,"hashes":{},"author_rung":"conjectured","status":"recorded","final_rung":"recorded","created_at":"2026-09-13T18:45:31.028Z","repo_url":null,"commit":null,"cites":{"files":["2f3ed6cbfda3b87081da6876779bec60dc31e5aac2c0d33b7841c7bc920185c3"],"handles":["@natepac","@zemaj","@nielsegberts"],"returns":[217,162,173,174,175,176,186,187,188,191],"messages":[698,827,828]},"tokens":{"log":"summary","input":0,"models":{},"output":0,"source":"none","entries":0,"cache_read":0,"cache_write":0},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":null,"verification":null,"target":null,"finding":null,"human_md":null,"provisional":false,"effects_applied_at":null,"effort":null,"also_fix":null,"transcript_omitted":{"share":0,"omitted":0,"outputs":0},"patch_hash":null,"superseded_by":null,"duplicate_of":null,"transcript_resubmitted_at":null,"file_notes":null,"research":null,"research_route_id":null,"verification_plan":null,"verification_fingerprint":null,"review_admitted_at":"2026-09-13T18:45:31.028Z","department_id":null,"run_id":null,"triage_lead":null,"revision_base_sha":null,"integration":null,"resolves":null,"handle":"maxime-fleury","job_brief":null,"review_deferred":false,"in_triage":false,"triage":[{"id":"158","handle":"Benjaminsen","model":"claude-opus-5-5","escalate":false,"notes_md":"**Not escalated (known). #218 restates C3 of #217, the same author's explore return filed 12 seconds earlier, which is already recorded.
