It ran on one machine on 2026-09-17, against a local copy of the endpoint before it went live. The director chair was held by Claude Opus 5 as a stand-in; the worker chair by Claude Fable 5.1. Both are Anthropic models, so this is a record of the mechanism working and of one model reviewing another from the same family. It is not a record of two labs agreeing. No GPT-6 Astra session took part. Chair labels and client names are self-reported; here they were set by the small script each model used to call the tools. Full revision texts are not in the log: each draft turn carries the sha256 of the revision it stored, and the final text is served by get_styleguide.",

You are right that 27 rules pointed at checkers the document never defined. The new section \"The checks\" defines them. I did not adopt the styleguide-check command or its exit codes, because no such program exists and naming one would be the same fault in a new place. The checks are real and they run at this endpoint: css. ids in the check_css tool, contrast in check_contrast. Every Enforced by line now says what the check reads. You expected some to read computed values; none do. Every css. check reads source text only, and the guide now says so, including that a check that could not run is not a pass.\n\n#7, PARTLY. layout.shift is split as you proposed, and CLS is a SHOULD with the field-measurement caveat. I did not add \"Enforced by: css.media-box\" to layout.box: the checker reads stylesheets, not markup, so it cannot see an img element. Claiming enforcement that does not exist is objection #3 again.\n\nThe checkers changed with the text, not only the prose: an empty reduced-motion block is now a finding, !important is accepted in reduced-motion and forced-colors blocks or beside a comment naming the rule, outline: none is accepted when a :focus-visible rule for the same element draws the ring, all 148 CSS named colors plus oklch(), color-mix() and the rest are literals, layout-property transitions are errors, and a root font-size other than 100 percent is a finding.\n\nFROM YOUR UNFILED NOTES, since I was tightening checks anyway: layout.z now allows only 0, 1 and -1 as written-out values; motion.duration makes the 500ms cap the MUST and states 120 to 320ms as the working range; layout.reflow no longer passes by clipping overflow and carries the two-dimensional-content exception.\n\nONE RULE YOU DID NOT ASK FOR: comp.auth, for SC 3.3.8 Accessible Authentication (Minimum) (AA), which your objection #17 named as missing without proposing text. Please review it like any other.\n\nNot done: forced-colors has no rule of its own yet. I agree it is missing.",

Pointing at the tools that do run, and stating in the document exactly what they read, is the better answer to my own objection. I accept the section as written.\n\nI also accept the consequence you state plainly rather than hide: several Check lines describe tests no source-text checker can perform. type.body-size says \"computed\". state.focus compares focused and unfocused pixels. motion.reduced reasons about the cascade and then reads JavaScript. What makes that honest instead of a lie is one sentence - \"No finding means the part of the rule that can be read from text was not broken, and nothing more.\" It is carrying a great deal of weight for one line. If the section is ever shortened, that is the sentence to keep.\n\n#7. Also right. A checker that reads stylesheets cannot see an img element, and an Enforced by line claiming otherwise would be objection #3 again. layout.box stays hand-checked. Agreed - though because it is hand-checked, its wording is now the whole of it, which is why I have objected to that wording separately.\n\nON THE RECORD, NOT BLOCKING:\n- layout.z states a cap of six layers that its new check no longer tests. As it stands the rule is failable only for not using var(). Either test the six or move it into the Why.\n- comp.hover-content omits SC 1.4.13's Dismissible exception - \"except when the additional content communicates an input error or does not obscure or replace other content\" - so an agent may file a false defect against an inline validation message. Smaller than what I filed; fix it when you are next in that rule.\n- color.dark still requires \"a user override\", which is a product decision, and its check tests only the literal-color half and color-scheme. A site that follows prefers-color-scheme and offers no toggle is not defective.\n- The checks section names one endpoint. That is honest for this table and may not travel with the document; line 60 covers the absence, so I let it stand.\n- copy.case, copy.no-filler and space.grid are still house taste carrying MUST.

I wrote a rule sentence no password sign-in can satisfy, and cited an AA criterion for it. It is the same class of error you found four times in round one, in the one rule I added without being asked.\n\n#24, ACCEPTED WITH ONE CHANGE. Your rewrite is right that the fault is clipping and not height, and I took it nearly whole. I did not take \"no text is limited by -webkit-line-clamp or line-clamp\" as an absolute. The W3C's own Understanding document for SC 1.4.12 says truncated text with an ellipsis meets the criterion \"so long as the content is still available\", and names the mechanisms: the text appears on focus or activation, or the truncated text is revealed on the linked page. An absolute ban would file a defect against every card grid that clamps a description and links to the full item, which is the too-absolute failure your objection was about. The text now reads: truncated text is a defect unless the full text is one activation away. The Basis line says where that allowance comes from.\n\nFROM YOUR NOTES, NOT BLOCKING, TAKEN ANYWAY: layout.z now tests its own six-layer cap (the check counts distinct layer tokens); comp.hover-content carries the criterion's Dismissible exception and its user-agent exception; color.dark no longer makes a user toggle a MUST.\n\nLEFT AS THEY ARE, AND WHY: the checks section still names one endpoint, for the reason you gave. copy.case, copy.no-filler and space.grid stay MUST as house style; the preamble already says the project's own conventions win over this guide, which is the release valve for taste.\n\nThe checkers changed with the text again: @keyframes steps are now parsed and judged for layout properties; system colors are accepted inside forced-colors and prefers-contrast blocks and are a finding anywhere else; a new css.clipped-text check warns on a fixed block size with overflow hidden or clip, on line-clamp and on text-overflow ellipsis, as warnings because source cannot say whether the full text is one activation away; and css.z-index counts layer tokens. type.spacing-override now carries an Enforced by line for that new check.\n\nIf nothing else stands in the way, the hash to sign is the one get_document prints for revision 3.

Your change is right, it is better than my text, and I checked it against the source rather than taking your word for it.\n\nThe W3C's Understanding document for SC 1.4.12 says, verbatim: \"Where ellipses appear as a result of modifying text style properties, the page can still meet the Text Spacing requirements, so long as the content is still available.\" It names the mechanisms: \"a mechanism is provided to reveal the truncated text on the page (for instance, the text appears on focus or on activation)\", and \"where the ellipsis is part of a section of content which includes a link, the truncated text is revealed on the linked page\". It states the other half just as plainly: \"Where text is not truncated but it is when text is spaced, if there is no mechanism to show the truncated text, it fails this success criterion.\"\n\nYour rule now reads: a defect unless the full text is one activation away, on focus, behind a disclosure, or on the page the truncated item links to. That is those three mechanisms, and your Basis line puts the allowance where it actually comes from - the Understanding document, not the normative criterion - which is the distinction I have been insisting on all along. An absolute ban would have failed every card grid that clamps a description and links to the item: the same too-absolute failure my objection was written to fix. I made it twice inside one rule and you caught the second one. Accepted as written.\n\nI also accept the three notes you took, and the two you left, including your reason for leaving them.

Your note says so outright - the check reports them \"as warnings because source cannot say whether the full text is one activation away.\" So it will report things that are not violations, and the document has no word for that. An agent that runs the check, reads line 58, and stops there files a defect against exactly the card grid your #24 change was written to protect. The rule got its exception back and the enforcement layer took it away again.\n\nIt is not only that check. css.grid-4 cannot resolve a rem, an em or a percentage to pixels. css.body-size and css.input-size are named on a rule whose own Check line says \"computed\". css.block-contrast cannot resolve a cascade. Each of them can report a thing that looks wrong in text and is right in a render. Line 58 currently promises that a source-only checker never produces a false positive, and that is a promise no source-only checker can keep.\n\nThe section already handles the opposite direction, and handles it well: \"No finding means the part of the rule that can be read from text was not broken, and nothing more.\" I called that sentence load-bearing and I meant it.

Accepted, and it went further than the sentence.\n\nYou were right that \"A finding is a violation\" had become false, and right about why: I had one word, severity, doing two jobs. It carried the rule's level (a SHOULD rule reported \"warn\") and it carried the checker's certainty (css.clipped-text reported \"warn\" because source cannot settle it). So a SHOULD-level certainty and a MUST-level guess looked identical, and the document promised more than the instrument could know.\n\nTHE TEXT. The third bullet of The checks is replaced by your three, nearly word for word. One addition: \"another stylesheet\" joins the list of places where the settling fact can live, because that is the commonest reason a snippet-level check is wrong (the reduced-motion reset and the focus ring are usually global).\n\nTHE MARKING. Nine checks are marked (source, warns), and I did mark whichever actually warn rather than the ones you could see from outside: css.body-size and css.input-size (the rule is about computed size; a later rule may override), css.block-contrast (what is really behind the text is a render question), css.duration and css.infinite (whether something is a progress indicator is not in the source), css.reduced-motion and css.focus-not-visible and css.outline-none (the fallback or the ring may live in another sheet), and css.clipped-text.\n\nONE PLACE I WENT THE OTHER WAY. You listed css.grid-4 as a check that must warn because it cannot resolve rem to pixels. I fixed the rule instead of softening the check: space.grid now says a multiple of 4px or of 0.25rem, and its Check says px values 4 does not divide, or rem values 0.25 does not divide, with em, percentages and calc() explicitly not judged. That is settled by source alone, so it stays a finding.\n\nTHE CHECKER. It now reports two separate things on every line: kind (finding or warning) and level (must or should, taken from the rule). A sheet fails on a MUST finding only; warnings never decide pass or fail, and the tool's output says an unresolved warning is unverified, not a defect. The list of warning checks lives in one place that both the guide's renderer and the checker read, so the (source, warns) marks and the behavior cannot drift apart. A test asserts, on a sheet built to break everything, that each check emits only the kind the guide says it emits.\n\nNot addressed, by your own choice and I agree with it: code.fonts states three things and checks one. The partial-enforcement sentences now cover it honestly.\n\nThe hash to sign is the one get_document prints for revision 4.",

There are two ways to satisfy that - lower the instrument's claim, or raise the rule's decidability - and I only offered you the first. You took the second where it was available. A warning that has to be resolved by hand on every sheet forever is friction; a rule that source can settle is not. Turning a MUST into an advisory when you could instead make it decidable would have been the worse trade, and I would have talked you into it.\n\nThe substance holds. 0.25rem is 4px at a 100 percent root, so the disjunction adds an expression of the same step rather than a second step - and it is the expression that scales with the reader, which sits better beside type.rem than the px form does. Replacing \"resolves to\" with \"is\" removes the word that was doing the damage: \"resolves\" demanded a computed value from a checker that reads text. And \"Values in em, percentages and calc() are not judged\" is an honest hole stated in the open, which is exactly what the new third bullet exists for - the rule still governs those values, the checker just stops pretending it can see them.\n\nThe nine markings are the right nine. I tested each against one question - does this rule turn on something source alone cannot settle? Computed size for body-size and input-size; what is actually behind the text for block-contrast; whether a thing is a progress indicator for duration and infinite; and another stylesheet for reduced-motion, outline-none and focus-not-visible. All nine hold. Your reason for choosing them yourself instead of taking my list is also the right one: you know the checkers and I was reading prose from outside the building.\n\n\"Warns instead of finding\" is stricter than my \"can warn as well as find\", and better for it. A check that emits exactly one kind is a check you can test, and you say it is tested against a sheet built to break everything. Adding \"another stylesheet\" to the list of places the settling fact can live is the other improvement on my text, and it is the commonest case of the five.\n\nONE RESERVATION, RECORDED AND NOT REOPENED: css.caps-tracking is unmarked, but \"every rule that sets text-transform: uppercase also sets letter-spacing of 0.06em or more\" can be answered by a letter-spacing in a different block or a different sheet - the same \"another stylesheet\" case you just wrote into the bullet. type.caps is a SHOULD and the check is true by its own wording, so it does not stand in the way; I also told this table in round three that everything but #32 was defensible, and I am not moving that line now.
