This is a\ncomparison of the served record. Earlier step check **#2169** (job #4752) is reused as instructed:\nit already established that route 128's step is open with respect to the three returns recorded\nafter #2072 (#2088,#2086,#2084) and the route's own returns. Only the **new** candidate listed for\nthis job, **#2176**, is examined here, plus the references needed to assess it.\n\n## What the step is\n\nRoute 128 (`active`, revision 11, `last_return_id` 2169) is the \"mirror-cut reversion audit\": a\ncountable deficit in the served edition of `research/QUESTIONS.md` plus the named instrument that\nmeasures it. Its served `next_step` is the fresh-baseline regeneration/diff procedure set by return\n**#2072**. The step object in this assignment's brief, the served route's `next_step`, #2072's\n`research.next_step`, and #2169's `research.next_step` are the same object: canonical (sorted-key)\nJSON sha256 `7ab3a088a7ba01364a1871e599a56472e2d7b79a9c0f26f2f3d4a8b46ac7879f`. The step this job\nchecks is exactly the step #2072 set, unrevised in the interval.\n\n## The new candidate: #2176\n\n#2176 (route **141**, `result`, `accepted` on the record) is the newest return in the window. It\nreports route 141's 17-row \"skipped queue\" obligation: 5 of 17 skipped rows map uniquely by content\npreimage to served paths and apply cleanly, 12 target no served file, with a passing positive\ncontrol. It is a served-`/docs` corpus, patch-applicability audit.\n\nIt does **not** answer route 128's step. Concretely:\n\n- It belongs to route **141** and carries route 141's own `next_step`\n  (canonical sha `d49b31e8…`), not route 128's `7ab3a088…`.\n- It contains **zero** route-128 content. Substring counts over `evidence_md + report_md +\n  research.evidence_md + research.prior_art_md + finding` for the route-128 term set\n  (`mirror`, `QUESTIONS.md`, `a3e07372`, `1828`, `route 128`, `centered-discrepancy`,\n  `global-factor`, `1954`, `corner-correlation`, `registry`, `reversion`, `cda1e669`,\n  `restore-83-153`, `served v10`, `mirror cut`) are **all 0**.\n- It neither regenerates the registry, re-measures the served v10 (`a3e07372`) bytes, restores\n  #83/#153, nor records the corner-correlation `#1954` supersession — the five things the step\n  asks for.\n\n## Why the step is still open\n\n1. **No return on route 128 since the step check.** The route's own `last_return_id` is 2169\n   (a `promising` step check that copied `7ab3a088…` forward); nothing on the route has been\n   recorded after it.\n2. **#2169 left the step open** and its conclusions are reused here; #2176 is the only return\n   recorded after #2072 that was not already assessed by #2169.\n3. **#2176 is off-route and off-topic.** A route-141 patch-applicability result cannot settle a\n   question about the served `research/QUESTIONS.md` registry and its git-derived `Display dates:`\n   preamble.\n\nNothing in the record answers the whole step or any part of it in a way #2072 did not already fold\nin. The step is neither settled (`known`) nor partly advanced by a later return (`progress`), so\nthe held pursuit (job #4623) should go out with this note and the step copied exactly.\n\n## Scope and disclosure\n\nThis finding is about the state of the served **record**, not about primes; it makes no\nmathematical claim and changes no route conclusion. No computation was reproduced. **45** of\n@Benjaminsen's returns still await a verdict (1 made on deepseek-v4-flash).\n","patch":null,"cpu_hours":0,"hashes":{},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-10-02T23:56:41.683Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[2176,2169,2072],"messages":[]},"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":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":{"outcome":"promising","route_id":128,"next_step":{"method":"Reconstruct the tree; do not re-base on a hash.
