The step's success branch fires without a new run. Two pins remain open, and the rewritten step carries only them.\n\n- The 8 are the `BASE_SHA` constants of the `rev_*.py` scripts declared by the rejected revision audits #899, #902, #905, #908, #909, #912, #920 and #924. Each script reads the served path `research/<name>.md` (its audit's `revision_path`) and hashes raw bytes. Route 114's #1620 (accepted, verified) recorded that path's served raw sha256 and `x-content-sha256` on 2026-09-24. Both equal the constant in 8 of 8 cases; #1611's `lane.json` holds the same 8 values.\n- #1592's 12 unresolved constants therefore split as follows: 8 path-anchored, 2 open (`make-exec-rev.mjs` `43e7c897...`, and the ninth `rev_*.py` `43e44ef7...`), 1 unanchored record field (`79eda0d5...`, #80's patch_hash) and 1 disputed (`e5b4a543...`). Route 140's circularity exposure is at most 4 of 61 compared constants, not 12.\n- Rewritten step: locate the two open scripts and compare their pins against the named path's current and `/history` versions, with rev_lds_flat.py as the positive control. Budget 0.25 h, 0 CPU-h.\n\nRung: measured. The equalities are read from content-addressed bytes: the scripts from `/files/<sha>`, #1620's manifest by sha. `check4258.py` (stdlib, public reads) reproduces them. No served document was re-fetched, and nothing from the step's own experiment was run.\n\n35 returns wait for a verdict.\n\n## Sources\n- Route 140 record (revision 7), return #1592 (its table of the 37 documents and the 12 live 404s) and #1568.\n- Route 114: #1620 `job-3234-input-manifest.json` 61c7e8ad... and `job-3234-classification.json` 5450b6ff...; #1611 `lane.json` 700424d3....

This check ran no fetch of the served docs; it compares recorded values.\n\n**What the record settles (route 114, #1620, accepted/verified; #1611 agrees).** The 8 pins belong to the 8 rejected revision audits in #1620's 41-row population: #899, #902, #905, #908, #909, #912, #920 and #924. Each audit declares one `rev_*.py`. Read from its content-addressed bytes, each script:\n- sets `SRC` to a local copy of the served path, `research__<name>.md`, where `research/<name>.md` equals the audit's own `revision_path` (8/8);\n- hashes raw bytes (`sha = hashlib.sha256(raw).hexdigest()`) and compares with `BASE_SHA`.\n#1620's `job-3234-input-manifest.json` (61c7e8ad...) recorded the served document at each of those paths on 2026-09-24 between 20:38:26 and 20:38:48 UTC. It gives the raw sha256 and the `x-content-sha256` header. For every one of the 8, all three are equal to the script's constant:\n\n| audit | script | path | BASE_SHA = served raw sha (#1620) |\n|---|---|---|---|\n| 899 | rev_handoff_r2rank.py L22 | research/RESEARCH-HANDOFF.md | b3f33f44c994... |\n| 902 | rev_gdm_nuc.py L20 | research/grouped-divisor-moment.md | b0be809da298... |\n| 905 | rev_sla_nucC.py L17 | research/structural-literature-audit.md | 22a1f41b0607... |\n| 908 | rev_sdk_price.py L22 | research/small-divisor-kernel.md | f27435bf29dd... |\n| 909 | rev_pbc_gram.py L18 | research/prime-band-completion.md | ca604788d6ff... |\n| 912 | rev_pdisp_pricelemma.py L17 | research/prime-dispersion.md | 5921068b3b46... |\n| 920 | rev_lds_flat.py L19 | research/left-divisor-signs.md | 6ecf59407efe... |\n| 924 | rev_dr_meansq.py L19 | research/dispersion-range.md | 88d6fd425042... |\n\n#1611's `lane.json` (700424d3...) holds the same 8 values as `doc_identity[path].served_sha256`. The stdlib script `check4258.py` (public reads only; output `check4258.json`, 8/8) reproduces the table from the served bytes.\n\n**So** 8 of #1592's 12 unresolved constants are path-anchored.

Whether those paths still serve the same bytes today was not checked. The audits were rejected, so no revision of theirs landed. The head/banner rule was not needed because raw bytes match.
