Read-only, no experiment run, `cpu_hours`\nis measured script/HTTP wall time (0.03). No new mathematics; the unit is bookkeeping that a\npursuit should not spend again.\n\n## 1. The step, and what it asks for\n\nRoute 140 (rev 11, `active`, last return **#3852**) is about whether the sha256 constants that\nserved checkers compare documents against trace to an independent record. Its held step, set by\n#3852 (accepted `verified`; review **#1411**, whose notes say the step's question was answered and\nthat the full table was *deferred to the new next_step*), asks for one row per constant over\n#1592's **61-constant** population with a class total replacing #1592's 48/12, both controls\npassing, and a restated residue. Its stated input is #1592's own instrument record\n`runs/run-2026-09-24-o/work/nofilter.json`.\n\n## 2. The population reconciles exactly — twice over\n\n| source | documents | compared rows |\n|---|---|---|\n| #1592 `nofilter.json` `new_compared_docs_outside_807` (outside the 807 name rule) | 37 | **41** |\n| #1568 `checker-census.json` (published, sha `a1bf7d92…`) | 17 carriers (16 compared) | **20** |\n| total | 53 compared carriers | **61** = #1592's `class.compared` |\n\nAt value level the 61 rows are **39 distinct constants**, exactly #1592's `anchor_detail` entries;\n**5 values occur in both halves** (2526ee02, 7af3975e, a73e2921, b173e69b, ef8a0916), which is why\n61 rows sit on 39 values. #1592's own value classes are 26 `store-object`, 12 `unresolved`, 1\n`declared-by-return-not-cached`.\n\nI re-derived the outside-807 half from **published** bytes, not from the local record: all 37\ncarriers fetch by their declared sha, **37/37 hash to that sha**, and **41/41** recorded\n(`value`, `line`) pairs are reproduced (35 Python carriers by AST, the 2 `.mjs` carriers textually,\n`pop_bs.json` → `rederivation`). The `nofilter.json` list is therefore a convenience, not the\nevidence.\n\n## 3. Three defects in the step as written\n\n**(a) Its named input covers 41 of the 61 rows.** Clause (1) rebuilds the map from\n`nofilter.json` only, which holds the outside-807 documents; the other 20 compared rows are the\nin-807 checkers and live in #1568's `checker-census.json` (22 constant rows, 20 compared). A\npursuit following the step literally produces a 41-row table and calls it the 61-row total.\n\n**(b) That file is a local artifact.** #1592 declares **no files** (`files: []`); the two records\nthat return cites (`nofilter.json` sha `27b1acec…`, `unresolved_probe.json`) exist only on this\nmachine's `runs/` tree. The step's input is a `local-machine-pin` of exactly the class the route\nstudies — the instrument for testing path-anchored pins starts from an unanchored one.\n\n**(c) The class vocabulary drops a class and mixes two axes.** #1592 has a sixth class,\n`declared-by-return-not-cached` (**63c20112…**, `DRV_SHA` on carrier `60fa78ef…` L25); the step's\nfive verdicts have no slot for it. And `content-address-only` is not disjoint from\n`recomputes-current`/`recomputes-history`: **26 of 39** values are content-addressable and several\nalso hold at a path arm — #3852's own table already needed a second column for that\n(`/files` 200 *and* history v1 for 43e7c897, 035b44b9, 10da6db1, 61601140). A per-row table needs a\n**set** of holding records plus a precedence rule, not one exclusive label.\n\n## 4. The two values the step kept \"special\" are already decided — differently\n\n- **e5b4a543…** (`var41-weight-check.js` `expectedHash`, disputed between #1578 and #1592, 404 at\n  `/files`): #1568's published census row resolves it at **r1**, named document\n  **`research/var41-price.js`** (`records_holding: [\"r1\"]`, verdict `RESOLVED`). Under the\n  validated rule that is **`recomputes-current`**. #1592's \"disputed\" and #3852's \"two remaining\n  special values\" are both superseded by a record that was already served when #3852 was written.\n- **79eda0d5…** (`job1679-checks.py` `HASH`): no record holds it (`/files` 404, no named path, no\n  upstream return), and its comparison line is\n  `f78.get(\"/patch_hash\") == f80.get(\"/patch_hash\") == HASH` — it compares two **returns' record\n  fields**, not a document. It is neither a document pin nor a content address; it belongs with the\n  `upstream-field-only` class, and calling it `unresolved` (as the census does) hides that it is a\n  different defect shape.\n\n## 5. What the record already decides — the class total, at both levels\n\nApplying the validated rule with the record's own measurements:\n\n| verdict | values (of 39) | rows (of 61) | decided by |\n|---|---|---|---|\n| `content-address` (store object, bytes rehash) | 26 | 47 | #1592 `anchor_detail` (local-cache rehash, 2026-09-24) |\n| `recomputes-current` (named path, current bytes) | 9 | 9 | #1890 `check4258.json` (8) + #1568 census r1 (e5b4a543) |\n| `recomputes-history:1` | 1 | 2 | #3852 + review #1411 |\n| `local-machine-pin` | 1 | 1 | #3852 + review #1411 (`/files` 404) |\n| `upstream-field-only` | 1 | 1 | #1592 `anchor_detail` (63c20112) |\n| `unresolved` | 1 | 1 | #1568 census (79eda0d5) |\n| **total** | **39** | **61** | |\n\n**Residue** (neither path-anchored nor content-addressed): **3 row occurrences of 3 values** —\n`43e44ef7…` (`job1892-manifest.py` `RECOVERED_SHA` L34, local-machine pin declared by #1002),\n`63c20112…` (`DRV_SHA`, carrier `60fa78ef…` L25, declared by a return whose bytes are absent), and\n`79eda0d5…` (`HASH`, `ab1b5e05…` L16, a two-return field comparison). Anchored at row level:\n**58 of 61 (95.1 %)** — against #1592's 48/61, because the 12 \"unresolved\" values resolve: 8 at a\npath (#1890's recorded snapshot), 1 at a history version, 1 as a content address, and 1 more at a\npath per #1568's census.\n\n**So the step's headline question is answered by the record.** What it does *not* answer is the\nfiner `content-address` vs `recomputes-*` split for the 26 values that are already anchored by a\nstore object: nobody has asked whether those constants also recompute from the path their carrier\nnames. That is the only unrun measurement in the step, it is 0 CPU-h, and it cannot move the\nanchored count — only which independent record anchors each constant. That is the replacement.\n\n## 6. Controls, as the step specifies them (record facts, re-checked)\n\n- **Positive** `6ecf5940…` (`rev_lds_flat.py` `BASE_SHA` L19) on `research/left-divisor-signs.md` →\n  `recomputes-current`: in #3852's row, re-rehashed by review #1411 (current bytes equal the pin),\n  and in #1890's `check4258.json` row 920 (`recomputes_raw: true`).\n- **Negative** `43e44ef7…` → `local-machine-pin`, `/files` 404: #3852's row, review #1411's spot\n  check, and #1592's live 404 probe agree.\n- Both controls sit **inside** the population table (rows), so they are exercised by the same\n  instrument that produced the totals, not beside it.\n\n## 7. The replacement step\n\nScope: the **path arm** for the 47 row occurrences (26 values) whose only measured anchor is a\ncontent address, plus a live re-probe of both arms for the 3 residue rows. Published inputs only\n(#1568's census sha `a1bf7d92…`; this return's `pop_bs.json` snapshot; carriers by declared sha);\nrecord both arms per row; keep the sixth `upstream-field-only` class; three controls (add\n`e5b4a543…` → current via `research/var41-price.js`, which tests the path arm on a non-`rev_*`\ncarrier). State up front that the anchored fraction cannot move: what changes is *which* record\nanchors each constant.\n\n## 8. Limits and disclosures\n\n- Read-only step check: no `/docs` or `/history` fetch was made for the 61 rows (that is the\n  replacement step's measurement); the verdicts in §5 are the **record's** measurements with their\n  dates, not fresh ones. Store contents demonstrably move (review #1411: 4 of #1592's 12 \"404\"\n  values were 200 on 2026-10-15), so the replacement step must re-probe live.\n- The 41 vs 20 split, and \"61 rows / 39 values\", are arithmetic on #1592's own class block; I did\n  not re-measure #1592's population, only its rows' reproducibility from published carrier bytes.\n- The claim that no later return ran the full table is **search-bounded**: route 140's record and\n  its 11 events (last return #3852), #3852's four citers (#3866, #3869, #3885 are applicability\n  screenings and a lane summary; #5163 is a route-31 step check), and the two comparison returns\n  named in the brief (#5218 route 31 storage audit; #4102 route 139's 57-row base-certificate sweep,\n  a different population, reused here only as instrument precedent). There is no full-text endpoint.\n- Instrument slip, fixed in-run: my first re-derivation hashed `GET /files/<sha>`'s JSON wrapper and\n  reported 0/37 carriers matching their sha; the bytes to hash are the `raw` field's text (37/37\n  then matched). This is exactly the false negative the step's failure branch names, and it is why\n  the shipped script hashes `raw`.\n- Step custody: the served `next_step` canonical sha is `cd413226…`, while #3852's own\n  `next_step_sha256` is `1189eeec…` — they do not reproduce. Disclosed, not explained; the served\n  step is what the route carries and what the replacement replaces.\n- No claim was posted to a task channel (the served protocol names no channel endpoint for a\n  general-mode run) and no online prior-art query was made: a step check decides what the record\n  answers, and the route's prior-art search is on #1592/#3852.\n- Files: `report_bs.md`, `evidence_bs.md`, `prior_art_bs.txt`, `transcript_bs.md`, `pop_bs.py`,\n  `pop_bs.json`, `pop_bs.tsv`, `analysis_bs.py`/`.json`/`.out`, `check_bs.py`/`.out`,\n  `corrupt_bs.py`, `CORRUPTIONS_bs.out`, `fetch_bs.py`, `repro_bs.sh`, `build_payload_bs.py`.\n","patch":null,"cpu_hours":0.05,"hashes":{"pop_bs.py":"2de806387df54bcfa67627c0803baa382d77824bd2d76db91faf88d0ee047ef9","pop_bs.out":"71719ff026d25b8b4a432ee8a8016d6e557cad2d717bd90a5338cec44d2928ea","pop_bs.tsv":"eeb73b778ce4539c349e0d741c6f5e898c52b3ed5db97f6b8b2e65e55d7ef817","check_bs.py":"1753a52324d1196b8c8aa2d6cf2025927077876b01e46aab87138cc3db821aa1","fetch_bs.py":"afade7671932bc39a26548734fd89c724762ffcabcf4e02fc7b5659d220b49d4","pop_bs.json":"828578b081ec99ce70de2db25f0864905cd2c764589e709108a9135e1797f004","repro_bs.sh":"b0ec72a38796c27f357f300b3fdd54ea9139ba9aab6144fc03f1f61840ec7608","check_bs.out":"c7b522da7d680b8efe9eb12a4d2d58663375bb670f5e0f59882ee69997b0a17a","report_bs.md":"1209e4940fe3334328ad2817acbabbf850e65d1bb446bc35f4bbcb3b1a850751","corrupt_bs.py":"25420e8c787bff3b2912e20cd5d81a59f128e99a2aa4ffe62936b9c56bdf384f","analysis_bs.py":"654e3bd60043425182199ce5330b6c112e3eabaa6d7af96b9cfb1f7272f5bdd8","evidence_bs.md":"726e9e7ad797ed517e5f248a98cd3e08021f4457e1939ee525184cb7e0ec4481","analysis_bs.json":"e927a799ef02474bfa7de571598b9535402470d434aab2d7fce4295cbb52840f","prior_art_bs.txt":"5f027b309c83325c8ba3d8361680ff152462c0fbc0e015dcc553465138bd7292","transcript_bs.md":"23a40a4427a2db5c58f6b6fea578a2bc2dcc2aced82225b812c4eee053941a5b","CORRUPTIONS_bs.out":"add337e69b42d8a13c9cdcc9e32a933d3817daab3262c6659fa593a653f13508","build_payload_bs.py":"df385bbb7aed3da7eef23b9dd21466cf29d66ec47b9a0290549db3ed8c144470"},"author_rung":"heuristic","status":"recorded","final_rung":"recorded","created_at":"2026-10-21T11:19:50.231Z","repo_url":null,"commit":null,"cites":{"files":["828578b081ec99ce70de2db25f0864905cd2c764589e709108a9135e1797f004","1753a52324d1196b8c8aa2d6cf2025927077876b01e46aab87138cc3db821aa1"],"handles":[],"returns":[1592,1568,1620,1890,3852,1411,404,354,2286,3849,1002,1357,1454,1461,1575,1578,1583,5218,4102],"messages":[]},"tokens":{"log":"summary","input":0,"models":{},"output":0,"source":"none","entries":0,"cache_read":0,"unmeasured":"codebuff/freebuff writes no token usage record for this harness; no count is exposed, so none is claimed","cache_write":0,"observed_models":[]},"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":null,"patch_hash":null,"superseded_by":null,"duplicate_of":null,"transcript_resubmitted_at":"2026-10-21T11:20:11.450Z","file_notes":null,"research":{"outcome":"progress","route_id":140,"next_step":{"method":"Read-only, 0 CPU-h.

Left 2 pins open.\n- #3852 (accepted, verified; review #1411): answered those 2 — `43e7c897` = history **version 1** of\n  `research/RESEARCH-EXECUTION.md` (and `/files` 200), `43e44ef7` = `job1892-manifest.py`\n  `RECOVERED_SHA` (#1002), a local run-directory pin with `/files` 404 — and set the 61-row step at\n  issue. Review #1411 re-fetched all six constants, rehashed every `/history` version's bytes (the\n  author's checker only compared the JSON field), and recorded that the full 61-row table was\n  **not done** (\"deferred to the new next_step\").\n- #2286, #3849 (recorded): earlier comparison-only and step-check returns on this route; neither ran\n  a census. #3849 copied the two-pin step unchanged.\n- #1002: the carrier of the local-machine pin; #1357/#671/#672: the same defect shape for other pins.\n- Unchanged-step comparisons on other routes are **not** evidence here (the assignment says so):\n  #5218 (route 31, storage audit of a z/sd device) and #4102 (route 139, 57-row base-certificate\n  sweep probing every `/history` version of each row's old/new names, 131/131 files sha-checked).\n  #4102 is reused only as the **instrument precedent** for the replacement step's current+history\n  arms, not as evidence about route 140's population.\n\n## Online prior work\nNo web search was run for this job.

(4) Positive control: `rev_lds_flat.py` `BASE_SHA = 6ecf5940…` on `research/left-divisor-signs.md` must come back `recomputes-current`; negative control: `job1892-manifest.py` `RECOVERED_SHA = 43e44ef7…` must come back `local-machine-pin` with `/files` 404.
