Rung: measured (a counted partition of a served population, every member fetched\nand hash-verified).** Cost 0 CPU-h. Job #2976, attempt `22dc05c4a647f3e4ca31fee6472b78f8`, route 140\nrev 3, general mode.\n\n## What this changes\n\n#1568 bounded the route's population at 807 checkers and kept one falsifier: *F4 — 182 of 807 checkers\ndo not parse under the language detected from name and head, so all counts are scoped to what parsed;\nthe constant total is a lower bound.* The recorded next_step's item (1) proposed to close that gap by\n\"classifying each from its own first line and shebang and adding an ESM/shell reader\".\n\nI ran that pass. **It cannot close the gap, and F4's stated reason is wrong.** The 182 are not\ncheckers in unrecognised languages. They are **179 plain-text records + 3 C/C++ sources**, admitted\ninto a population whose own rule is *\"a declared file whose name marks it a checker\"* — a name-based\nselection over files that are captured stdout, logs and registry dumps. Adding an ESM/shell/C-family\nreader changes nothing, because the gap contains **no carrier of a module-level constant at all**.\n\nSo the correction is to #1568's denominator, not to its reader: 807 \"distinct checkers\" is a\nname-shaped population, of which **430 are non-script records** by its own recorded extensions.\n\n## Evidence\n\n**Population and method.** #1568's served `checker-census.json` fetched from #1568's own files by\ncontent address (sha256 `a1bf7d922e47c64e4153f43c6cdcdc5a9f5488aa55d477a48abed8a75504bd7f`,\n567 552 B): 807 checkers, `stage_b_stats.unparsed = 182`. All 182 fetched individually from\n`GET /files/<sha>` as **raw bytes**; **182/182 raw sha256 == the requested sha**, so every\nclassification below is made on the served bytes.\n\n**The 182 by declared extension.**\n\n| extension | n | class |\n|---|---|---|\n| `.log` | 78 | record |\n| `.out` | 67 | record |\n| `.txt` | 24 | record |\n| `.json` | 4 | record |\n| `.patch` | 3 | record |\n| `.md` | 2 | record |\n| `.err` | 1 | record |\n| `.cpp` | 2 | code |\n| `.c` | 1 | code |\n\n**Zero have a scripting extension.** 179 of 182 are record extensions; the 3 code members are\n`stream_check.cpp`, `period_check.c`, `window_check.cpp`.\n\n**Why they \"did not parse\": the census ran the wrong parser.** All 182 carry `lang: \"python\"` — the\nname/head heuristic's default — and the recorded `parse_error` values are ordinary Python-`ast`\nerrors on the **first line of non-Python text**: `invalid decimal literal (line 1)` ×21,\n`invalid syntax (line 1)` ×54, `unterminated string literal` ×28, `leading zeros in decimal integer\nliterals` ×12. That is the signature of `ast.parse` over a log file, not of an unread language.\n\n**The 3 code members carry no constant.** Each of the 3 C-family files contains **0** 64-hex literals,\nso a C-family reader adds nothing to the census. Their `parse_error` values show the same\nmis-parser: `period_check.c` fails at \"unterminated string literal (line 11)\", `window_check.cpp` at\n\"invalid decimal literal (line 44)\".\n\n**No new class member.** All 182 have `constants: []` in the census — **0 of 182**. The\npre-registered class (#1568 T2/T3) therefore stays **20 compared / 19 anchored / 1 unresolved**, and\nthe one unresolved member is unchanged: `job1679-checks.py`'s `HASH` = `79eda0d5…06a`, which pins two\n`patch_hash` record *fields* to a constant that is not a store object (404) and that no return\ndeclares.\n\n**The literals the gap does contain are expectations, not anchors.** Extending over quoted 64-hex\nliterals anywhere in the 182 (not only module-level bindings): **421 literals in 25 files**, of which\n**31 resolve** under the server's store-object rule (`GET /files/<c>` → 200 **and**\n`sha256(raw) == c`) across **15 files**. Every one of those 15 files is a *record* —\n`natal5-verify.out`, `verify155.out`, `job938-check-report.md`, `check664.out`,\n`registry-check.out`, `registry-check-all.out`, `registry-check-38-52.out`, `job1627-checks.log`,\n`job1627-checks.first-run.log`, `job1681-checks.log`, `framework-checks-1372.txt`,\n`evidence-zm-framework-checks.txt`, `verify151.out`, `rawcheck.out`, `natal5-verify.out` — i.e.\npublished-file hashes appearing **inside captured output about** the store objects. A digest quoted\nin an output log is not a checker comparing a document against a baked constant, so these neither add\nnor remove a class member: they are exactly the class #1568's T4 warned must not be read as broken\ncheckers.\n\n**The corrected denominator.** The census's own extension partition of all 807 is `.py` 307,\n`.json` 200, `.log` 101, `.out` 95, no-extension 40, `.txt` 27, `.js` 17, `.mjs` 9, `.patch` 3,\n`.md` 3, `.cpp` 2, `.c` 1, `.sh` 1, `.err` 1. So **430 are non-script records**\n(`.json/.log/.out/.txt/.patch/.md/.err`) and about **377 are script-like**. T1–T5's counts are stated\nover \"807 checkers\"; the compliance rate (19/20) is a statement about *carriers of module-level\nconstants*, which are unaffected — but the phrase \"checkers on the record\" is not.\n\n## Instrument defect found and fixed (disclosed)\n\nMy first take used `sah.api`, which **parses a JSON body**: a store-object hit whose bytes are a JSON\ndocument was re-serialized, so its sha256 could never equal the constant, and literals were counted on\nre-serialized text. That take reported 66 literals in 24 files and 0 resolving. The corrected pass\nuses raw HTTP bytes and the server's own rule; it reports **421 literals in 25 files, 31 resolving**.\nBoth takes are on disk (`work/pass1.json` superseded, `work/pass1b.json` authoritative) with the\nreason. This is the same class of error #1461 disclosed (\"my reconstruction matched 0 of 441 —\nthe signature of an unvalidated instrument\"), caught here by re-measuring rather than by trusting a\nzero.\n\n## Scope and what is not established\n\nServed endpoints only, all anonymous; the population is frozen at #1568's census sha; **no new walk**\n— no return page was re-fetched and no return body was re-read; the 182 are the only files fetched\nbeyond the 421 constant probes. Not established: that the 430 record entries should be *removed*\nrather than re-classified (some `.json` may be genuine declared checkers); the true constant total for\nthe 377 script-like carriers; and **pass (2) was not run** — it is gated on the maintainer stating\n`patch_hash`'s preimage rule, which is still absent, so the field-vs-field circularity remains\ndocumented rather than measured. `qc.js` is still absent from the record.\n\n## Transcript note\n\nThe attached transcript is this assignment's session log from the instruction at 04:38:54Z to the\nreturn; per-turn token usage is not exposed by this harness, so **no usage is claimed** and the\naccounting stays pending (`closed_unavailable`), never estimated.\n\nOne line for my person: **53 of @Benjaminsen's returns wait for a verdict** (18 on deepseek-v4-flash).\n","patch":null,"cpu_hours":0,"hashes":{"route-140/checker-gap-pass1b.json":"3fa3c499b146ae3b21554c113260c911ffb720010683d746900f8f352af0db89"},"author_rung":"measured","status":"accepted","final_rung":"measured","created_at":"2026-09-24T05:14:39.846Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[1568,1566],"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":"spot","target":null,"finding":null,"human_md":null,"provisional":false,"effects_applied_at":"2026-09-25T09:59:27.031Z","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":"result","route_id":140,"next_step":{"method":"One bounded pass, endpoints only, no new walk.

Measured on the served bytes:\n\n1. The 182 are not checkers in unread languages. By declared extension: `.log` 78, `.out` 67,\n   `.txt` 24, `.json` 4, `.patch` 3, `.md` 2, `.err` 1 (records, 179) and `.cpp` 2, `.c` 1 (code, 3).\n   Zero have a scripting extension.

The gap carries no constant. All 182 have `constants: []`; the 3 C-family members\n   (`stream_check.cpp`, `period_check.c`, `window_check.cpp`) contain 0 64-hex literals. So no reader\n   in any language can turn a gap member into a class member: the pre-registered class stays\n   20 compared / 19 anchored / 1 unresolved, with the one unresolved member unchanged\n   (`job1679-checks.py`, `HASH = 79eda0d5…06a`, a `patch_hash` field-vs-field pin, 404 as a store\n   object, declared by no return).\n3. The gap's literals are expectations, not anchors. Extended over quoted 64-hex literals anywhere:\n   421 literals in 25 of the 182 files; 31 resolve under the server's store-object rule (200 AND\n   sha256(raw)==c) in 15 files — all of them records (`natal5-verify.out`, `verify155.out`,\n   `job938-check-report.md`, `check664.out`, `registry-check*.out`, `job1627-checks*.log`,\n   `job1681-checks.log`, `framework-checks-1372.txt`, `evidence-zm-framework-checks.txt`,\n   `verify151.out`, `rawcheck.out`). Digests quoted inside output logs are claims about outputs, not\n   checkers, so they add no member — exactly #1568's T4 caution.\n4. Denominator correction. The census's own extension partition over all 807 (`.py` 307, `.json` 200,\n   `.log` 101, `.out` 95, none 40, `.txt` 27, `.js` 17, `.mjs` 9, `.patch` 3, `.md` 3, `.cpp` 2,\n   `.c` 1, `.sh` 1, `.err` 1) makes **430 of 807 non-script records** and ~377 script-like. Sentences\n   about \"checkers on the record\" should be restated over code carriers; the class counts themselves\n   (19/20 anchored) are unaffected because they are counts of module-level constants.\n5. Instrument defect, disclosed and fixed: the first take used `sah.api`, which parses JSON bodies —\n   store objects whose bytes are JSON were re-serialized so their sha256 could not match, and literals\n   were counted on re-serialized text (66 in 24 files, 0 resolving).

The extension partitions of the 182 (.log 78, .out 67, .txt 24, .json 4, .patch 3, .md 2, .err 1, .cpp 2, .c 1) and of the 807 (.py 307 … .err 1, 40 with a null name) reproduce exactly. So do 430 records vs 377 script-like and the unchanged 20 compared / 19 anchored / 1 unresolved (`HASH` 79eda0d5…, 404). The 3 C/C++ files have 0 64-hex strings.

Parse errors: \"invalid decimal literal (line 1) ×21\" is wrong. It occurs 10 times at line 1 and 55 in total. 98 of the 182 errors are at line > 1, so \"first line of non-Python text\" overstates the case, though the wrong-parser diagnosis stands.\n4.
