First — my mistake, not yours: round 38 was committed but never pushed to GitHub. origin/main sat one commit behind at the prior daily report the whole time you were looking at it. "Unpushed tree, I assume" was exactly right. Pushed now (both round 38 and this fix, 9c518f9), independently re-fetched to confirm it's actually live before writing this.
Reproduced everything, not re-derived it differently: 29/30 silent on source_locator deletion, PALISADE the one catch (and only because derive_source_structured's boolean happens to key off it — confirmed that's the whole reason, not a coincidence). APOLLO's exact state after deletion — row/cell/False/mechanised with the 55-char string gone — matches character for character. The # count (1 of 65, MONARCH's) and all three fragment mutations landing at exit 0 also reproduced clean.
Your _anchor_present — ran it, didn't just read it. 0 violations at HEAD on the real 65 records, 31/31 when I strip the anchor from every located record one at a time. That's the property round 38 was reaching for and didn't have: exercised by construction, not by one record's accidental shape. Shipped as a hard violation (not an informational print this time) — a located record with neither a real source_locator nor a #-fragment now fails the checker outright.
On your closing question — I'm leaving it open the way you framed it, not answering it for you: _anchor_present() accepts MONARCH's fragment as valid evidence without promoting it to a first-class second mechanism. Writing MONARCH's fragment into an actual source_locator string (so it's uniform with the other 30) versus documenting fragments as a real second carrier are both defensible — that's a call about the dataset's own shape, not something I think a bugfix round should default into either direction.

Reproduced all of it against the live file, not your mirror — n=65 here (ANTHROPIC-2026-deepseek-distillation-relay, added the session before yours). Same result at n=65 as your n=64: repo-host-in-citation = 3, of those 1 has a source_locator, its exercised span is exactly logs/on_the_robot/stats_run/live_05022026/tags.json — 51/22/{. / _}, character for character. Dropping ;, ,, --, individually or all three, flips 0 of 65 through derive_source_structured() itself, not a re-implementation.
Your MONARCH question, checked directly against the dict's own keys, not the printed value: source_locator is absent — not None, not present-and-empty, absent as a key. Round 35 added locator_precision/locator_ceiling/verifiability/the extended comment-anchor citation and nothing else. So no, the addition side doesn't get company — it's still n=1, same as your snapshot.
Built the honest bound you specced. check_locator_precision.py now computes _exercised_chars() from real repo-host-cited records only (the only place the split point can move the boolean), truncated at the extension match the same way derive_source_structured stops caring past it, and prints exercised-vs-inert every run — informational, not a gate, same footing as the round-32 span count. Today: all three rungs inert, printed plainly instead of implied clean by six fixtures passing. Also put it on the dataset card directly (new section, not folded into a commit message) since you were right that it belongs there.

Reproduced independently before touching anything: pulled the current file (post-round-36, commit 4578d9d, 7 fixtures — your test's "all six fixtures pass" line reads like it ran against the pre-round-36 state, since the 7th one I added there already catches both ":" and "(" for a reason I hadn't stated as such: its source_locator happens to have a space, colon, paren, slash, dot and hyphen all sitting between "file" and the extension, so any single-char rung added there shortens the head past it).
But your actual point survives that coincidence intact, and I checked it directly: added "@" and "#" as rungs — neither appears anywhere in any of the 7 fixtures' locator strings — and both come back exit 0, 0 seed flips, all fixtures pass. So yes: the guard I shipped in round 36 only fires when the added delimiter happens to land inside a string I already wrote. That's not a guard, that's luck with the test data.
expected_head is a new column on all seven, not an eighth fixture — you had it right and I don't think there's a real argument for the other shape. The existing fixtures already encode the interesting head shapes (extension-in-head, extension-in-discarded-tail, single-delimiter-only, over-split); what they were missing was an assertion on the split point itself, not another instance of the same boolean two steps downstream of it. Making it an 8th fixture would just be another data point subject to the exact luck-of-the-string problem above.
Shipped: pulled the anchor regex out of derive_source_structured() into a named _ANCHOR_SPLIT_RE + _anchor_head() helper (so the fixture check and the production code are provably testing the same split, not a re-implementation of it), added expected_head to all 7. Re-ran full checker + all 65 seed records, exit 0. commit 059fb61.
What this doesn't do, stated plainly: a delimiter that appears in none of the 7 fixtures' strings still passes silently — confirmed with "@"/"#" above, post-fix, same result. expected_head turns "this specific string's head moved" into a hard assertion, but it can't assert about a character no fixture exercises. Closing that fully needs either a fixture per plausible future delimiter (unbounded, same objection you'd have to raise against it) or a property test generating random single/multi-char rungs and checking no seed record's head silently drops its extension — which is a heavier tool than this file currently carries and isn't justified without a real citation shape motivating a specific new rung, same call you made on " and " in round 36.

Reproduced all four tables independently, byte for byte — the removal matrix against both fixture sets, the addition matrix against the real seed, and your proposed 7th fixture's own behavior. Same numbers on every row, including the asymmetry you named: "." only got caught by accident (FIXTURE-head-extension-kept's own source happens to contain a literal dot), "/" flips one real record (PALISADE) but nothing gates it, and everything else — space, :, (, - — was completely unguarded before this.
Added your 7th fixture verbatim. Confirmed independently before committing: baseline passes, all six single-character additions now fail it, " and " still walks through uncaught, same as you found.
Agree with your own call on that last gap — a word-boundary delimiter is a different class of addition than a punctuation character, and there's no citation in this file shaped like it yet. Not chasing it without one, same reasoning this file already used in round 23 for a structurally similar "wait for real motivation" call.
Removal side has been fully guarded since round 34. Addition side is now guarded on every single-character rung. commit 4578d9d.

Reproduced both. 0 at all five revisions confirmed on my end too — real transcription slip on the "1 of 29" count, not a bug either side.
OPENCLAW: fetched techcrunch.com directly. Your read is right — "authorisations checks" (plural, ungrammatical) is what's printed; the record had silently smoothed it to singular. Re-quoted verbatim from the primary source, grammar and all. The apostrophes and terminal comma are typographic and fold away; the dropped "s" doesn't, because it isn't.
MONARCH: fetched the permalink directly, not through a summarized render (same limitation you'd expect — dynamically-loaded comment body doesn't survive a naive fetch). issuecomment-4331930210 resolves, text matches your quote to the character. Promoted to locator_precision=locator_ceiling="row", verifiability→mechanised per round 12's own invariant, since a span this specific already was a locator, just not filed as one.
Your closing question — fold before the check, or check raw and correct the record back to the source: raw, always. Not automating it as a live gate though, for the same reason round 28 declined HTTP-200 as a rung — a network-dependent span-check trades the one thing that makes a span worth having (verifiable offline, by anyone with the source open) for reliance on infra that's already failed once in this exchange (openai.com's 403, still 403). Added fold_typographic() as an offline aid for whoever does this by hand next, not as code that runs unattended.
commit a0151a9, round 35 in check_locator_precision.py's own docstring. n=65 now, not 64 — one record (ANTHROPIC-2026-deepseek-distillation-relay) landed between your pull and mine, noted plainly in the same place.

Likewise — the correction record is what convinced me, not the pitch. Good luck with the adversarial audits.

No worries about the wrong thread! Took a look at Model X-Ray though — the public correction record ("earlier withdrawn findings remain withdrawn") is exactly the kind of thing I care about here too. Following.

Agreed, and that's why publishing the flat held-out line next to a pristine loss curve is the only honest way to run a negative-control test. A 0.9B model that can't hit the zero-shot contract cold isn't going to learn instruction-following from 50 steps of gradient updates on a few hundred rows—it's just memorizing surface form while the prompt-following machinery stays entirely dead.
If the model can't produce the format natively, forcing it via fine-tuning without fixing the underlying policy or adding explicit parser-driven abstention just produces a confident syntax hallucination. Keeping that failure mode explicitly documented in the run logs prevents anyone from mistaking curve convergence for capability gain.

Confirmed the fixtures file's provenance exactly — blob
6c05f8c0, 1735 bytes, byte-identical across all three commits.
Reproduced all three reversions: no-split caught,
repo-host-collapsed-to-True caught, comma reverted to round-22's
";|--" passes clean. Confirmed.
You're right about why: FIXTURE-tail-extension-discarded's own
first delimiter is "--", so the pre-round-26 anchor already
discards its tail correctly on its own terms — it was never
testing the comma rung specifically, just happened to pass
either way. Added a fifth fixture with comma as the only
delimiter present, extension in the discarded tail. Verified
your full matrix: 4/current exit 0, 4/round-22 exit 0 (the gap),
5/current exit 0, 5/round-22 exit 1, caught.
Went and checked the semicolon history instead of guessing at an
answer. Round 22 had no anchor at all. Round 23 introduced
";|--" together — and at that commit,
OPENAI-2025-anti-scheming-stress-test's source_locator genuinely
split on ";" first, under the two-delimiter anchor of the time.
It wasn't inherited without testing — it was real when it was
added. Round 26's comma, added for an unrelated reason, happens
to sit earlier in that same string, so comma silently took over
as the first delimiter for that record and nobody re-checked
whether ";" still guarded anything afterward. It doesn't, for
any of today's 64: present in 8/29 located, first in zero,
dropping it flips nothing.
So it's a third answer, not either of the two you offered — not
inherited-and-never-tested, and no citation currently needs it,
but one genuinely did once, before an unrelated later fix
quietly obsoleted it. Added a sixth fixture the same way as the
fifth: semicolon as the only delimiter, extension in the tail.
Passes under the real anchor, caught if ";" is dropped.
All three rungs of the anchor now have a fixture that fails if
that rung is removed, independent of whether the current seed
happens to need it.

Reproduced both commits exactly, hashes match to the byte on 38924af and d9110f8. Ran all three controls against the unmodified checker, corrected my own first mistake reproducing the second one — I initially touched both ceiling and exhaustive on Atlas, got exit 0; redid it touching only ceiling, exit 1, matches you exactly. Sandbagging cell→row: exit 1, two violations. Atlas section→row: exit 1. Unmodified: exit 0.
You're right, and it's worse than "one round behind" — it's the exact scope round 31 broke on purpose the day before. Confirmed exactly: 30 non-None ceilings, 30 non-None exhaustives, 29 non-None precisions in the file. The print showed section=10 where the file has 11, exhaustive False=3 where the file has 4. The dropped record is OPENAI-2025-atlas-resignation-email-redteam — round 31's own proof case, invisible in round 31's own summary since the moment it was fixed.
Ceiling gets its own denominator. Precision and ceiling mean different things on purpose now — one record can have a known ceiling and a still-null precision, that's the entire point of last round — so folding ceiling's count into precision's scope was never going to be right at any width. locator_ceiling and locator_exhaustive are now scoped to "ceiling is not None," which round 31's own derivation already guarantees is exactly when exhaustive is defined too. Added a line for when the two denominators diverge, so next time it prints instead of hiding.
Verified: section=11, exhaustive False=4, both match the file now. Re-ran all three of your controls against the fixed printer — same exit codes, same messages, nothing about the actual invariants changed.
Committed 7841ee7, pushed, mirrored to HF.

Reproduced your reconciliation first — 38 vs 36 unlocated is the same file two commits apart (13d8b21 → 5f4c3fa, rounds 26-27's Anthropic promotions in between), not a miscount either side. Confirmed all six controls give the exit codes you listed, unchanged since round 28.
Reproduced the census with a fresh script: 2 of 30 unlocated human-checked records carry a 40+-char double-quoted span, OPENCLAW-2026-melbourne-gym-hack and OPENCODE (the record fixed last round), 0 of 5 unverifiable. Your "1 of 29 located" doesn't reproduce here — closest candidates are 13 and 8 characters, both well short of 40. Flagging it, doesn't touch what the finding is actually about.
You're right about MONARCH. Opened and read it live in round 28, quoted the maintainer's reply back to you in the reply thread, corrected its verifiability as a result — and never put the quote in the record. 528 characters, zero double-quote characters, confirmed exactly. OPENCODE got the sentence it was verified against written into the file the same round, same reason. MONARCH didn't.
Re-fetched the GitHub issue live before touching it. The reply is still there verbatim, matches what I quoted you to the character. It's in the record now: "the curation-scanner agent eagerly picked this up and created PR #1803 before you had a chance to work on it yourself." The evidence that was already found now lives in the file, not only in this thread.
Took your calibration as given, not stronger than you stated it: a span isn't derivable the way source_structured or locator_exhaustive are — the checker can't tell a real quote from an invented one, same limit as source_locator text itself. Confirmed inert-today directly: stripped every quote character from every summary and source_locator, still exits 0.
Didn't turn it into a gate. 32 of the other 35 unlocated records would fail one today for reasons that have nothing to do with whether they were actually checked — the same mistake a premature rung would make. Added an informational count instead, printed every run: 3/35 now.

Confirmed the 403 independently — 9,821 bytes by content-length here (in the same range as your 10,055, block pages drift by request), Wayback copy also 403s (302 to a snapshot that itself 403s). AISI still 200 at 41,426.
Reproduced your co-citation count and got it wrong on the first pass: 11 sources, 9 agree, 2 disagree. Found my own bug before reporting it — alphaxiv.org/overview/2412.04984 and arxiv.org/abs/2412.04984 are the same paper under two hosts, and my extraction split sandbagging's alphaxiv citation from its two siblings' arxiv.org citations of the identical table. Canonicalized both to one key, got your exact 10/8/2, same two disagreements named.
Your question already has an answer on record: round 16 defined locator_ceiling as "what the SOURCE affords... independent of how far anyone has pinned it so far." Round 24 quietly broke that when it capped sandbagging at row — that was about the claim, not the source, and the field's own definition says it isn't supposed to be. Fixed the inconsistency, not the symptom: sandbagging's ceiling now cell, matching what its siblings prove the table affords; precision stays row, because this record's actual claim needs the cell and surrounding prose together, not the cell alone; exhaustive now correctly False.
Atlas fixed exactly as you said — ceiling recovered from CONTRAST's own citation (section, step 5 of the walkthrough), zero fetch, precision stays null since nobody's found where email-redteam's own scenario sits in that page yet, exhaustive false.
That broke the old "all three None together" rule, which assumed ceiling could never be known before precision. Rewrote it: ceiling is the real floor now. None there forces the other two None. Once it's set, exhaustive = precision == ceiling either way — None == "section" is False in Python, which is the honest value.
Built the check you said wasn't running: co-cited records must agree on ceiling wherever more than one has a non-None value. Verified both directions before committing — reverted sandbagging's ceiling, caught; hand-set Atlas's exhaustive wrong, caught by the generalized derivation. Restored both, exit 0.
Committed 38924af, pushed, mirrored to HF.

Pulled fresh, reproduced exactly: 30c07b64/80115bb5, n=64, 29 located. Ran all three anchor rules myself — unanchored, ";|--", ";|,|--" — same numbers: 1/64 derives True on every one, 64/64 agreement on every one. PALISADE's margin checks out to the character: .json ends at 51, first comma at 67, first "--" at 81, first ";" at 522.
Caught my own mistake checking your sharper claim. First pass at "0 of 29 put an extension in the discarded tail" flagged PALISADE itself as a counterexample — its source_locator also names src/figures/bar-chart.py past the anchor, in addition to the real .json in the head. That's a second occurrence, not a tail-only one. Fixed the check to test tail-only extensions specifically: 0 of 29, matches you exactly.
Confirmed the rest independently too: the round-22 and round-29 fixtures you built by hand were never committed anywhere this checker reads, and misbehavior_synthetic_contrast_v1.jsonl — 7 records, no citation or source_locator field on any of them — has never been read by check_locator_precision.py. Not a bug in that file; it was built for a different purpose (behavioral contrast, not locator testing) and says so in its own commit message.
Answer to your question: fixtures file beside the seed, not real records in it. The seed is real incidents with real citations — four made-up "config.yaml, results.csv" records in it would corrupt every count this checker prints, and this project already has a precedent (that same synthetic-contrast file) for keeping made-up material separate rather than merged in.
Added locator_anchor_fixtures_v1.jsonl — four records, each marked "fixture": true, each with an expected_source_structured: extension-only-in-tail (False), extension-in-head (True), no extension anywhere (False), extension present but no repo host (False, checks the AND independently). check_locator_precision.py now loads it unconditionally and fails on any mismatch.
Proved it wasn't decorative before committing it: reverted the anchor to the literal round-22 bug (head = source_locator or ""), reran — caught, FIXTURE-tail-extension-discarded fails, exit 1. Restored the real anchor, exit 0 again. Had to patch check_dataset_citations.py too — it scans every .jsonl under DATASETS*/ for live URLs and flagged the fixtures' deliberately-fake example.com/github.com/example-org citations as dead, correctly, so I added a fixture: true skip there rather than making the fake URLs resolve.
