Subject: [PATCH 01/36] fix(core): decline index coverage on a partial sitemap
 read

The sitemap walk caps entries at 500 and child sitemaps at 10. A page
missing from the part it read may be listed in the part it skipped, so
discovery-index-coverage now returns notApplicable instead of failing.
Found on a large retail site whose 2455-URL product sitemap filled the
cap before the one-URL sitemap that lists the homepage.

 The shared sitemap gatherer uses the scanned homepage directory as the site root when it is a detected or declared subpath homepage. It reads declarations from the origin's robots.txt, then tries the conventional sitemap names under that directory before the origin fallbacks. Shared sitemap files contribute only absolute URLs on the same origin and under that directory. Filtering precedes the entry cap and sampling. Relative or malformed loc values associated with this site remain available to content audits. A sibling-only sitemap does not prove that this site has a sitemap. The child-fetch cap remains in force even when all children cover siblings.
 
 Content-page scans do not infer a mount. Origin files, origin probes, feed discovery, explicit page overrides, and redirect handling keep their existing scope. This change limits sitemap-derived evidence; it does not make every scan request subpath-only.

+### Partial sitemap reads decline the verdict (2026-10-06)
+
+The shared sitemap walk keeps at most 500 entries and reads at most 10 child sitemaps. When it stops early, a page missing from the entries it kept may still be listed in the part it skipped. The audit now returns `na` for that case instead of `fail` or `warn`. A page found in the partial read still passes, and a page missing from a complete read still fails.
+
+The trigger was a large retail site. Its index lists a 2455-URL product sitemap before a one-URL sitemap that holds the homepage. The product file filled the cap, and the audit failed the homepage as unindexed.
+
+## Deferred
+
+- The fetcher cuts a sitemap body at 5 MB and does not flag the cut. A `<loc>` lost to that cut is still read as absent. The walk needs a body-truncation flag before this audit can decline that case too.
+- After the entry cap is reached, the walk still downloads the remaining child sitemaps and discards their entries.

Subject: [PATCH 02/36] fix(core): read only page dates in lastmod
 verifiability

Nested Review, Comment, Answer and Question dates record when someone
else wrote, not when the page changed. Reading them as page signals
reported product pages that publish no page date as divergent instead
of unverifiable.

Count lastmods within one hour as one build stamp. A generator that
writes the clock per URL spreads one run over seconds, and exact
string matching missed it.

+### Page signals exclude contributed dates (2026-10-06)
+
+The sketch says to parse all JSON-LD blocks for `dateModified` and `datePublished`. The audit reads those dates only from nodes that describe the page: top-level nodes, `@graph` members and what they nest. It skips a nested `Review`, `Comment`, `Answer` or `Question`. Those dates record when someone else wrote, not when the page changed. A top-level `Review` is the page itself and keeps its dates.
+
+The trigger was a large retail site. Its product pages publish no modification time, but each one nests customer reviews. The review dates were read as page signals, and five pages with no page date were reported as divergent. They are now unverifiable.
+
+### A build stamp is one run, not one string (2026-10-06)
+
+The claim is "one identical lastmod equal to the last deploy date". The audit compared lastmod strings exactly. A generator that writes the clock per URL spreads one run over seconds, and exact matching saw every value as different. One large retail site stamped 2451 product URLs between 09:57:16 and 09:57:33 on one day. The audit now counts the largest group of sampled values inside a one-hour window. The 90% share and the 3-day recency rules are unchanged. Values hours apart still count as separate dates.

Subject: [PATCH 03/36] fix(core): pass crawler bots allowed through the
 catch-all group

The 14 per-bot robots.txt audits warned at 0.5 when a bot was allowed
only through User-agent: *. Under RFC 9309 section 2.2.1 that is the
same access a named group grants, and no vendor documents a
difference. They now pass and name the group that applied. A blocked
bot still fails. A missing or unreadable robots.txt is not applicable.
Control-token copy no longer says Google-Extended or Applebot-Extended
crawl.

+The per-bot robots.txt checks, such as `access-crawl-control/gptbot` and `google-extended`, now pass a bot allowed through `User-agent: *` instead of warning, and say which group applied. A missing or unreadable robots.txt is not applicable, and the fix text now warns that a named `Allow: /` group drops the catch-all rules.

Subject: [PATCH 04/36] fix(core): pass ai-bot-directives when bots inherit the
 catch-all

The audit warned when YouBot or AI2Bot was allowed through User-agent: *.
Its only reason was that the policy could flip under a later blanket
block; no source documents a difference, and RFC 9309 section 2.2.1
grants the same access. The dossier is corrected first. Inherited access
now passes and names the rule that applied; a block still fails. A
missing or soft-404 robots.txt is not applicable.

-**Falsifiable claim:** Two AI bots have operators who publish crawler documentation naming the product token: YouBot (You.com) and AI2Bot (Allen Institute). For those, a `User-agent:` group in `robots.txt` is read by the operator. It determines whether the site enters that operator's corpus or index. A `Disallow: /` for those tokens therefore closes a documented consumer path; an explicit `Allow: /` keeps it open and pins the policy against a later blanket block.

 **Falsifiable the other way:** for the three remaining tokens (Bytespider, cohere-ai, Diffbot) no such documented reader could be located, and for Bytespider the directive is measured being ignored. Those rows are therefore reported but never scored — blocking them is a legitimate operational choice with no measurable AI-answer cost.

 Note the internal consistency this restores — and note that the two cases are _not_ symmetric. The _same_ TollBit finding capped Bytespider at C — "the consumer exists but the mechanism is empirically unreliable" — while YouBot kept an A. One of the two stamps had to move. Only YouBot's needed to, and only by one step. Bytespider's C rests on **two** negatives: no vendor documentation of any kind **plus** measured non-compliance. YouBot's demotion rests on **one**: measured non-compliance _despite_ vendor documentation that is the most detailed of the five. Documented-but-unreliable is a strictly stronger evidence position than undocumented-and-unreliable, which is exactly why YouBot lands at B rather than being dragged down to Bytespider's C.
 
-That is also the disposition of YouBot inside this audit. **YouBot's own contribution is held at B, not C, and it stays in the scored set.** An unreliable mechanism is still a documented mechanism. A YouBot directive therefore continues to move the score: a block fails, and a wildcard-only allow warns. The cap is therefore a live judgement, with a re-review trigger in both directions. If a later measurement round finds YouBot honouring `robots.txt` after all, the A case reopens and this section should be re-litigated. If sustained non-compliance is confirmed instead, YouBot leaves the scored set, and the merged grade rests on AI2Bot alone (see counter-evidence below).

 - **The scored pair is low-volume.** Neither YouBot nor AI2Bot appears in a Cloudflare Radar top-five breakdown. The audit scores the _documentedness_ of the directive, not traffic, and its weight (0.6, grade B) is priced accordingly — it cannot dominate a category the way five weight-1.0 checks did.
 - **YouBot's compliance claim is disputed** (TollBit). If a future re-review confirms sustained non-compliance, YouBot drops out of the scored set and the merged grade falls to B on AI2Bot alone (weight unchanged) — or to C/informative if AI2Bot's evidence also degrades.
-- **"Allow" is not universally correct — but the score is not neutral about it either.** Blocking either scored bot is a defensible publisher choice, and the audit says so at medium, never high, priority. The three states mean this. An explicit `Allow: /` for YouBot and AI2Bot is the **pass**: the documented consumer path is open and pinned. A bot left to `User-agent: *` is a **warn**: the policy is unstated, and it flips the day a blanket block lands. An explicit `Disallow: /` for either bot is a **fail**: a documented compliant consumer path is closed, and the audit records that cost rather than hiding it. Stating a block deliberately is more honest than inheriting one, but it does not neutralise the fail. The fail is the recorded price of the choice, not an accusation of a mistake. The fix text is written so that following it never scores worse than doing nothing.
+- **"Allow" is not universally correct, and the score does not reward stating it.** Blocking either scored bot is a defensible publisher choice, and the audit says so at medium, never high, priority. Two states remain. A bot whose applicable rules permit `/` passes, whether the rule is its own group, the catch-all `*`, or no group at all: under RFC 9309 §2.2.1 the three grant identical access. A `Disallow: /` that reaches either bot is a **fail**: a documented compliant consumer path is closed, and the audit records that cost rather than hiding it. The fail is the recorded price of the choice, not an accusation of a mistake. The fix text is written so that following it never scores worse than doing nothing.
 - **Overlaps** with `access-crawl-control/no-blanket-block` (2.22) and `access-crawl-control/agent-governance` (2.28), both of which read the same file. All three now consume the shared RFC 9309 gatherer, so parsing behaviour (BOM, exact-match, wildcard paths) is fixed in one place.
 
+## Implementation deviations
+
+### Inherited access passes (2026-10-06)
+
+The audit warned at 0.5 when YouBot or AI2Bot was allowed through
+`User-agent: *` or by no rule at all. The stated reason was that the policy
+"flips the day a blanket block is added".
+
+No source supports that warn. Neither You.com nor the Allen Institute documents
+treating a named `Allow: /` group differently from inherited access. RFC 9309
+§2.2.1 makes a crawler obey the group that names its product token and fall
+back to `*` only when none exists, so the two states grant identical access.
+A later blanket block is a future edit, and this audit fails it when it lands.
+Scoring a risk the site has not taken is speculation the evidence policy does
+not allow.
+
+The named-group advice also had a cost. A `User-agent: YouBot` / `Allow: /`
+group replaces the catch-all for YouBot, so it drops every catch-all
+`Disallow` the site meant to apply.
+
+The rule now asks one question per scored bot: do the rules that apply to it
+permit `/`? A block that reaches either bot still fails. An unreadable
+robots.txt is not applicable, as in `access-crawl-control/meta-external-agent`:
+missing, non-200, empty, or a 200 that parses to no groups and no directives.
+A site with no robots.txt had received the same warn as a site with an open
+catch-all. Neither is penalised now.
+
+The title moved from "AI bot directives are explicit" to "Documented AI bots
+allowed by robots.txt". The failure title moved to "A documented AI bot is
+blocked in robots.txt", because a block is now the only failing state. The
+per-bot table keeps its stance labels: "allowed by default" is still an
+accurate description of a row. `guidance.code` still shows the named
+`Allow: /` snippet, and the fix text carries the caveat.
+
+Grade, tier and weight are unchanged at B, scored, 0.6.
+
+## Deferred
+
+- **A 5xx robots.txt.** RFC 9309 §2.3.1.4 tells a crawler to assume a complete
+  disallow when robots.txt is unreachable. This audit reports any non-200 as
+  not applicable and does not grade that case.

 ## Review history
 
 - 2026-08-20 — code review (11-agent workflow) + evidence research (12-domain workflow, 400 sources) on the five source audits.
 - 2026-08-21 — five dossiers generated; REWORK-TODO records the consolidation requirement.
 - 2026-08-22 — consolidated into this audit (Plan 4, Task 2). Source dossiers preserved at [`docs/evidence/merged/access-crawl-control/`](../../merged/access-crawl-control/).

Subject: [PATCH 05/36] fix(core): treat AI-usage silence as not applicable in
 coherence audit

The audit reports contradictions between channels; a site with no
signal in any channel has nothing to contradict. The dossier called
silence a real cost with no source, while its own sources read absence
as unknown or no preference. Dossier corrected first; notes stay in
details.

Subject: [PATCH 06/36] fix(core): ignore RSL path guesses that return no RSL
 document

When nothing advertises an RSL licence, the audit guesses /license.xml
and /rsl.xml. A site that redirects both to its homepage got four
conformance errors about the homepage HTML. A guessed path is now kept
only when its body has an <rsl> element; otherwise the audit returns
notApplicable.

+### A guessed path must return an RSL document (2026-10-06)

+The conventional-path probe keeps a candidate only when its body has an

+homepage HTML as a licence: four conformance errors about a document the site
+never published. A guess that lands on HTML is now absent, and the audit
+returns not applicable.
+
+The test is the body, not the redirect. A conventional path that redirects to
+a real RSL document still counts and still warns as not discoverable. The
+content type is not the test either: an RSL document served as `text/xml` is
+still reported. Advertised candidates are not filtered, so a `License:` line

Subject: [PATCH 07/36] fix(core): read a redirected root .txt probe as absent

Random root .txt paths that 301 to the homepage were reported as an SPA
catch-all, because the audit counted the homepage's final 200. A probe
whose final path differs from the requested one now counts as absent.
An HTML 200 at the requested path still fails.

+
+The sketch follows redirects and asserts the final status. A large retail site
+redirected every unknown root `.txt` path to its homepage, so both probes ended
+on a 200 HTML page and the audit reported an SPA catch-all. The 200 belonged to

+catch-all that answers 200 at the requested path, so that a real key file and

+real IndexNow key file answers 200 at its own path, and a missing one answers
+a redirect. A probe whose final URL has a different path from the one
+requested now counts as absent, like a 404. A redirect that keeps the path, such as

Subject: [PATCH 08/36] fix(core): stop reading a form Turnstile loader as a
 bot wall

A readable storefront that loads the Turnstile api.js for its forms
still drew three findings. cart-handoff-reachability now fails only a
cart that is a challenge page or only a widget. no-bot-detection passes
a loader on a page the scan could read. no-blocking-captcha matches
vendor script src and widget elements instead of the vendor name, so
inline config, CSP lists and prose no longer match.

+### A loader on a readable page passes (2026-10-06)
+
+The page-script branch warned at weight 1 on any page whose HTML contained a
+challenge host, including `challenges.cloudflare.com`. The counter-evidence
+grades that sub-signal D, and the required fix says to warn only when the
+widget gates the main content. A loader is now reported only on a page that
+served no readable text, using the per-page `renderedByPage` verdict from the
+scan evidence (`pageRendersText` when it is absent). A loader on a page the
+scan read is named in a pass, because no wall was observed and the page was
+read. The `wafProtection` branch, which carries the A grade, is unchanged.
+Script-`src` scoping and a UA probe are still open items from the review above.

 - **Without a platform fingerprint the audit is not applicable, not failing.** It still probes `/cart` and `/checkout`, but when neither answers it reports `notApplicable`: the paths were a guess. With a fingerprint, an unanswered cart path is a failure, because the platform's own convention says where it should be.
 - **The JS-only arm needs both halves.** A document warns only when its visible text is under 200 characters _and_ it carries no `<noscript>` content. A short page with a real fallback passes.
 
+### A challenge widget fails only when it is the document (2026-10-06)
+
+Sketch item (b) fails a cart document that references a challenge widget by
+URL substring. A large retail site served a readable cart with the Turnstile
+loader (`api.js?render=explicit`) included site-wide for its login and
+newsletter forms. The cart was readable, and the audit failed it.
+
+The claimed mechanism is a handoff that dead-ends on a challenge. The
+guidance asks a site to challenge the payment submission rather than the
+document, and a widget on a form of a readable cart does exactly that. The
+audit now fails in two cases. First, when the shared WAF detector
+(`detectWafProtection`, the logic the scan gate uses) reads the cart response as a
+challenge page. Second, when a widget is mounted on a document with under 200
+characters of visible text, the same threshold the JS-only arm uses, so the
+challenge is all there is to read. A widget on a readable cart passes.
+
 ## Deferred
 
 - **The ACP `continue_url` itself is never probed.** Reaching it needs a Cart API session, which needs credentials and a POST. The audit probes the storefront cart the same handoff lands on.

+### Detection reads widget markup, not body text (2026-10-06)
+
+The audit matched `recaptcha`, `hcaptcha` and `turnstile` anywhere in the
+body. A large retail site's inline config (`provider = "CloudflareTurnstile"`)
+matched as a CAPTCHA. Detection now uses the selectors the review asks for: a
+`<script src>` from the vendor's loader path, or the element the widget mounts
+on (`.g-recaptcha`, `.h-captcha`, `.cf-turnstile`). Prose, config and CSP text
+no longer match. A Turnstile, reCAPTCHA or hCaptcha widget on a form still

+  mode do not stop an agent. The markup alone does not say which mode a widget
+  runs in: the mode is usually set in the vendor dashboard or in a script

Subject: [PATCH 09/36] fix(core): read the largest article in the semantic
 extractor

The semantic extractor took the first <article>. On a page with many, that was a promo strip, and extraction determinism reported 0.00 agreement. It now takes the article with the most text, and falls back to the body when none holds a fifth of the page.

+The semantic extractor behind `content-extraction/extraction-determinism` now reads the `<article>` with the most text, not the first one. When no article holds at least a fifth of the page's text, it falls back to the body. A promo strip marked up as the page's first `<article>` no longer reads as the page.

+### The semantic extractor reads the largest article (2026-10-06)
+
+The sketch names the semantic step "first non-empty of main, [role=main], article". The code took the first `<article>` element. A page may carry many, and the first is often a promo strip. A large retail site with no `<main>` opened its body with a 145-character ticker in an `<article>`. The semantic extraction was that ticker, and the audit reported 0.00 agreement.
+
+`main` and `[role=main]` still take the first non-empty match, because a page declares one main region. For `article`, the extractor now takes the element with the most chrome-stripped text. It keeps that element only when it holds at least 20% of the body's chrome-stripped text. Below that it is one card among many, and the extractor falls back to the body, as the example failure describes. On the retail page the largest article held 3.5% of the text. The worst pair moved from 0.00 to 0.56, and the page still fails: readability keeps about half the page.
+
+The fallback also reaches `token-ratio`, `preamble-tax`, `boilerplate-tax` and `site-wide-passage-uniqueness-ratio`, but only when Readability declines the document. No verdict in the real-page corpus moved.

Subject: [PATCH 10/36] fix(core): match stripper class tokens, not substrings

The aggressive extractor dropped any element whose class contained a blocklisted word, which deleted a page wrapper named page-content--banner-enabled. It now tests whole class tokens and ids, and keeps an element holding most of the page. Script contents no longer count as prose, so JSON-LD URLs stop being key spans.

+### Class tokens, not substrings (2026-10-06)
+
+The stripper matched its blocklist as a substring of the joined class and id string. `/banner/` matched `page-content--banner-enabled`, the wrapper that holds a whole page on a large retail site, so the aggressive extractor deleted everything and every key span was reported lost. Firecrawl's `excludeNonMainTags` lists class and id selectors such as `.ad`, `.sidebar`, `.cookie` and `#share`, and a class selector names a whole token ([removeUnwantedElements.ts](https://github.com/firecrawl/firecrawl/blob/main/apps/api/src/scraper/scrapeURL/lib/removeUnwantedElements.ts), verified 2026-10-06). Each class token and the id are now tested against `/^(?:comments?|sidebar|promo|related|advert|ads?|banner|cookie|newsletter|share)$/i`. The old `ad-` prefix becomes the `ad` and `ads` tokens, as in Firecrawl's list.
+
+An element that matches is still kept when it holds more than half the page's text after the tag pass. A rule that would delete most of the page has matched the page, not a widget. Firecrawl guards the same way: it keeps an excluded element that contains a main-content marker.
+
+### Script text is not prose (2026-10-06)
+
+JSON-LD strings are key spans only when the prose carries them. The audit tested that against `$("body").text()`, which includes `<script>` contents, so a JSON-LD block in the body vouched for its own URLs. They became key spans that no extractor keeps. The prose test and the `textRatio` denominator now drop `script`, `style`, `noscript` and `template` first.
+
+On the retail page, recall moved from 0 to 0.818, and the page still fails: readability drops the tile headings. Verdicts that moved in the real-page corpus: `atlassian-com-pricing-shell` fail → na, because its only key spans were JSON-LD strings in scripts.

Subject: [PATCH 11/36] fix(core): take only sentences as text-fragment answer
 spans

The span after an h2/h3 was whatever text followed it. A tile grid became one answer crossing every block, and a one-word button repeated under each tile became an ambiguous answer. Heading spans now have to be sentences of three or more words; a sentence split across sibling blocks is still reported.

+### Heading spans must be sentences (2026-10-06)
+
+The sketch's span is "the first sentence after each h2/h3". The audit took the text of whatever followed the heading and, finding no sentence terminator, used all of it. On a large retail site that turned a grid of 28 product tiles into one "answer" crossing every tile's block. It also turned a one-word button repeated under every tile into an ambiguous answer. Neither is a sentence, and both were reported as unaddressable.
+
+A heading-derived span now follows four rules. A heading that follows a heading introduces no span. A following element with no block-level descendant contributes its first sentence. A wrapper with block-level descendants contributes the sentence its leaf blocks finish within three blocks. A sentence split across sibling paragraphs stays a candidate and still fails, which is the failure the block rule describes. A wrapper that finishes no sentence there is a grid, carousel or menu and is skipped. Spans under three words are labels and are skipped. `dd` and FAQPage answers are unchanged.

Every dropped candidate was a menu list, a tile or topic grid, a heading or a short label.

Subject: [PATCH 12/36] fix(core): read every JSON-LD shape in feed parity

Image arrays and ImageObjects were read as no image. A ProductGroup's
AggregateOffer range and variant offer prices were read as no price,
and productGroupID did not count as an item group. Resolve seller @id
references on the page; a dangling reference still fails.

+### JSON-LD shapes for image, price, seller and group (2026-10-06)
+
+The audit read one shape per field, and a large retail site's variant pages
+used the others. Each field now reads every shape schema.org allows.
+
+- **Image.** A string, an array of URLs, or an `ImageObject` with `url` or
+  `contentUrl`. The first usable entry is the primary image. An array was
+  reported as "no image".
+- **Price.** `offers.price`, then an `AggregateOffer`'s `lowPrice`, then the
+  first variant Offer's `price` under `hasVariant`. A `ProductGroup` carries a
+  range, not a price, and was reported as "price undefined".
+- **Item group.** `productGroupID` on a `ProductGroup` now counts beside
+  `inProductGroupWithID` and `isVariantOf`. It is the group identifier the
+  group node itself carries.
+- **Seller.** An `offers.seller` written as `{ "@id": … }` is resolved against
+  the nodes on the same page. A reference to a node the page never defines
+  still fails, and the message names the dangling `@id`.

Subject: [PATCH 13/36] fix(core): skip search and locator forms in autofill
 coverage

A store locator's 'City or postcode' box matched the postal-code
keyword and failed the audit. Query forms take a keyword or place, not
profile data. Skip them, and skip location fields whose name offers a
choice between concepts.

+### Search and store-locator forms are out of scope (2026-10-06)
+
+The audit judges fields an agent fills from the user's profile. A site
+search or a store locator takes a keyword or a place to look up, so no
+autofill token applies to it. A large retail site was failed for its store
+locator's "City or postcode" box.

+- A form is skipped when it has `role="search"`, sits inside a search
+  landmark, holds an `input type="search"`, or its action path, name or id
+  reads as search, locator or stores.
+- "find" is not a skip keyword. Checkout postcode-lookup forms are often
+  named "find address", and their postcode field does owe its token.
+- A location field whose visible name offers a choice between concepts
+  ("City or postcode", "Ville ou code postal") is not counted. Two names for
+  one concept ("State or province") still are. Sign-in fields such as
+  "Email or username" are unaffected; `username` is their token.
+- A scan whose only candidate fields sit in skipped forms is not applicable.

Subject: [PATCH 14/36] fix(core): skip empty layout sections in
 section-headings

Page builders emit whitespace-only <section> row slots. They have
nothing to label and dragged a homepage to fail. Skip them, and return
not applicable when no section has content, as the dossier requires.

 **Counter-evidence:** The falsifiable claim that survives is 'headings must exist and be real elements'. The stricter claim audited by sequential-headings is that levels must never skip, as in h2 to h4. That claim has no documented consumer. Every splitter and snapshot cited tolerates skipped levels, and simply records whatever level it finds. No vendor doc or study shows a measured penalty for skipped levels in LLM parsing. Google states outright that 'there are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary' [google-ai-features-docs], so no AI-search vendor endorses heading structure as an extraction or ranking requirement. LangChain is a library used by site owners' own pipelines, not a public crawler of third-party sites — treat it as mechanism evidence, not proof that ChatGPT chunks your page this way.
 
+## Implementation deviations
+
+### Empty layout sections are skipped (2026-10-06)
+
+A `<section>` with no text outside scripts and styles, and no image, video,
+audio, iframe, SVG, canvas, object or embed, is an empty layout slot. It is
+counted in neither side of the ratio. `found` reports how many were skipped.
+A large retail site's homepage carried four empty row slots out of seven and
+failed on them.
+
+### No `<section>` is not applicable (2026-10-06)
+
+The zero-sections branch returns `notApplicable` instead of `warn`, as the
+required fix above asks. A page whose only sections are empty slots is also
+not applicable. The pass / warn / fail split is unchanged: all labeled
+passes, a majority warns, the rest fails. The review sets no other threshold.
+
+## Deferred
+
+- **First-child heading test.** The heading check still accepts a heading at
+  any depth. The required fix's first-element-child rule is not applied here.
+- **Label validation.** A whitespace-only `aria-label` and an
+  `aria-labelledby` pointing at a missing id are still accepted.

Subject: [PATCH 15/36] fix(core): rss-feed is not applicable without a feed

A feed is optional and the dossier says the audit informs rather than
penalises. Return not applicable when no feed answers and no page
advertises one. An advertised feed that does not answer still fails.

+### No feed and no link is not applicable (2026-10-06)
+
+The audit failed every site without a feed. The grade decision says the
+audit "informs rather than penalises", and the test gaps list a site with no
+blog as "should be N/A, currently FAIL". It now returns `notApplicable` when
+no feed answers and no page carries an autodiscovery `<link>`. A site whose
+`<link>` advertises a feed that does not answer still fails, as the merge
+decision above requires. The message names the advertised URL.
+
+The narrower page-type gate the required fix suggests ("no article/blog-type
+pages") is not used. Advertising is the site's own statement that a feed
+exists, and the scan observes it directly.

Subject: [PATCH 16/36] fix(core): webmcp forms not applicable without WebMCP
 markup

WebMCP is an origin trial, and a site that registers tools imperatively
carries no declarative attribute. Return not applicable when no form
carries one; present but broken markup is still judged.

 - **"Every form should be a tool" is kept as the pass bar.** The partial-coverage `warn` is inherited unchanged from the pre-rewrite audit. It is arguably too strong — a login or newsletter form is not obviously something a site wants agents driving — but narrowing which forms are in scope is a design question beyond this pass-condition rewrite, and the `warn` (not `fail`) keeps it advisory.
 - **Adoption is ~0.0000027 of Chrome page loads**, so this audit still reports a finding on essentially every site scanned. That is a property of the signal's age, not of the check; the grade-A evidence is what the rubric prices, and the softened priority is what keeps it from dominating the recommendation list.
 
+## Implementation deviations
+
+### No WebMCP attribute is not applicable (2026-10-06)
+
+A site whose forms carry none of `toolname`, `tooldescription`,
+`toolparamdescription` or `toolautosubmit` is not judged. The counter-evidence
+below says a site using the imperative API carries none of them and is still
+agent-callable, and the API is an origin trial. Failing every form-bearing
+site measured adoption of a draft, not a defect.
+
+Markup that is present is still judged. A description or parameter
+description without a `toolname` fails, an empty `toolname` fails, and a site
+that names some forms and not others warns. This supersedes the rewrite's
+note that the audit "still reports a finding on essentially every site
+scanned".

 ## Evidence
 
 ### Signal: declarative WebMCP attributes read by the browser — grade B (agent-tools)

The grade-B study measured informational content, and the dossier asks
for a content-page scope. A storefront homepage was failed for carrying
no statistics. Also read euro, pound and comma-decimal amounts.

 - 2026-08-26 — the shared text helper this audit reads, `getMainContentText`, changed its selection. Among several `<main>` elements it now returns the one holding the most text rather than the first, it ignores a `<main>` inside a `<template>`, and it falls back to the whole `<body>` only when no `<main>` holds any text. Measured cause (scan evidence gate design, section 2.4): storefronts ship empty or fragmented `<main>` wrappers, and the first one is often a stub. Two consequences for this audit. A page whose real content sits in a later `<main>` is now measured on that content. A page whose every `<main>` is empty is now measured on its body text, page chrome included, where it previously measured as empty.

+scan holds none. A large retail site's homepage was failed for carrying no
+statistics.
+
+Required fix #2 lands. A currency figure now reads `$`, `€` and `£`, leading
+or trailing, with comma or dot decimals and comma, dot or no-break-space
+thousands groups. `49,99 €`, `1.200,50 €` and `£29.99` each count once. A
+percentage may use a comma decimal and a space before the sign (`12,5 %`). A
+bare comma decimal with no unit still counts as nothing.
+
+## Deferred
+
+- **Prices still count as figures (fix #1).** A content page that lists
+  prices can pass on them. The content-page scope removes the product-grid
+  path; the in-sentence test is not built.
+- **Per-page threshold (fix #3), rename (fix #4) and chrome exclusion
+  (fix #5)** are unchanged.
+
 ## Evidence
 
 _No dedicated evidence signal was researched for this audit in the 2026-08-20 pass. Its tier assignment falls to the taxonomy design; unproven mechanisms default to informative per the [evidence policy](../../policy.md)._

Subject: [PATCH 18/36] fix(core): accept cross-domain and PDF policy links in
 ACP link surface

The ACP Link schema asks only for url: string, format: uri. The
same-domain and text/html rules came from the dossier's own sketch,
not a source. HTTPS, isSafeUrl on every hop, the 3-redirect cap and the
200 rule stay; a PDF must carry the %PDF- signature.

+### Policy links on another domain, and PDF policies (2026-10-06)
+
+The implementation sketch required every link and every redirect hop to stay
+on the merchant's registrable domain, and required `text/html`. No cited
+source asks for either. The ACP `Link` schema in `openapi.agentic_checkout.yaml`
+(2026-04-17) asks only for `url: string, format: uri`. The OpenAI feed spec
+asks for `seller_tos` and `seller_privacy_policy` as a public URL. A large
+retail site linked both policies to a sister brand domain, which redirected
+to a PDF on the brand's asset CDN. Both hard gates failed on that, and the
+audit declared the catalogue ineligible for checkout without a source.
+
+Both rules are dropped. A link may point at any domain and redirect across
+domains. Every hop still passes `isSafeUrl()`, still counts toward the
+3-redirect cap, and the target must still be HTTPS and answer 200.
+
+A target served as `application/pdf` is accepted when its body starts with
+the `%PDF-` signature. The soft-404 and 500-character text checks read HTML,
+so they apply to HTML targets only. A PDF's text is not extracted: the core
+package carries no PDF parser, and no source makes a PDF policy unusable.
+Any other content type still fails.

+### `display` is resolved per selector (2026-10-06)
+
+The scanner counted a rule as hiding when `display:none` appeared anywhere in
+its block. A large retail site ships blocks like
+`.box{display:none;position:relative;display:block}`, where the later
+declaration wins and the box is visible. Counting it reported text a human
+sees as ghost content.
+
+`display` is now resolved per selector. Within a block the last declaration
+wins. A selector list is split on its top-level commas. A later rule for the
+identical selector in the same at-rule context overrides an earlier one, and
+`!important` outranks a plain declaration. This supersedes "no cascade" for
+that one case only. There is still no specificity: different selectors are
+never ranked against each other. A collapsed panel hidden by
+`.panel{display:none}` and opened by `.panel.open{display:block}` stays
+counted, as the mechanism requires. An override inside a media query does not
+cancel a base rule, so parallel desktop and mobile copies stay counted.
+
+Source order is the gatherer's order: inline `<style>` blocks first, then
+linked same-origin sheets. A linked sheet placed before an inline block in the
+document is read after it.

+- 2026-10-06 — three parts of the required fix above now ship. A small
+  marketing site failed on seven hits, and none was a missing heading: bold
+  statistics (`25,000+`, `4.9 / 5`, `87%`), brand labels in interface chrome,
+  and a label inside a hidden dialog.
+  - Text made only of figures and punctuation is a value, not a title, and is
+    skipped.
+  - The excluded ancestors grow to the list the fix names: `header`, `aside`,
+    `label`, `figcaption`, `summary`, `dialog`, `[role=dialog]`,
+    `[role=navigation]` and `[role=banner]`, beside `nav`, `footer`, `button`
+    and `a`.
+  - Subtrees the markup hides (`hidden`, `aria-hidden="true"`, inline
+    `display:none`, a closed `<dialog>`, `<template>`) are skipped, through the
+    shared `hiddenFromReaders()` helper.
+  - Bold text inside a `section` or `article` that already has a real heading
+    is emphasis within that section. The fix flags only "where a heading is
+    structurally missing", so it is skipped.
+    Five real-page corpus verdicts moved, every one away from a false hit:
+    prices on a plans page (fail → warn; one "Custom" price label remains),
+    syntax-highlighted code tokens (fail → pass), menu headlines in a retail
+    header (fail → pass), template placeholders (warn → pass), and inline
+    `<strong>` emphasis in documentation prose (fail → pass).
+    Still open from the required fix: whole-token class matching, the extra
+    class vocabulary, and a per-page threshold.

+block child and bare text yielded no block for the bare text. On a small
+marketing site, each feature card was `<li><h3>…</h3><span>answer</span></li>`.
+The answer sat in the `li`, the `li` was not a leaf, and every answer was
+reported as crossing a block boundary.
+
+The audit now does the walk step 3 of the sketch describes. Each text node
+belongs to its nearest block ancestor, and the run of text nodes that share
+one is a block, broken at every block-level child. A leaf block is one run.
+The `li` above yields two runs, the heading's and the answer's. This replaces
+the leaf-block deviation above and closes the first Deferred item below.
+
+Two further rules came with it:
+
+- **The matcher searches rendered text only.** The spec skips text that is
+  not rendered. A subtree the markup hides (`hidden`, inline `display:none` or
+  `visibility:hidden`, a closed `<dialog>`, `<template>`) yields no heading
+  candidate and does not count toward ambiguity. `hidden="until-found"` and
+  `aria-hidden` content stay searchable: find-in-page reveals the first, and
+  the second is still rendered. A declared FAQPage answer that sits only in
+  hidden text now fails with that reason, not with "crosses a block boundary".
+- **A card title is not the start of its description.** When a block that
+  ends no sentence is followed by one that opens with a capital letter, the
+  first was a label, and the sentence starts at the second. A sentence split
+  across sibling blocks continues in lower case and still fails.
+
+Verdicts that moved in the real-page corpus: `allbirds-com-collection` fail →
+warn (a hazard warning remains); `bbc-co-uk-article`, `canada-ca-income-tax`
+and `hiutdenim-co-uk` fail → pass; `irs-gov-form-1040`, `otto-de-category` and
+`tattly-com-shell` fail → na, whose only candidates sat in hidden menus,
+flyouts or a search panel; `stripe-com-pricing` pass → fail, whose three
+FAQPage answers are only in `display:none` accordion panels. That last move
+corrects a false pass.

-- Text that sits directly in a wrapper beside block-level children, such as an alert `div` holding an `h4` label and bare text, is not followed. Only the wrapper's leaf blocks are. Following direct text needs the per-text-node block-ancestor walk the sketch describes.
+- Heading spans are still collected from the element after an `h2`/`h3` and its leaf blocks. Bare text beside block children inside that element, such as an alert `div` holding an `h4` and bare text, is matched correctly now but is not taken as the span.
+- CSS `display` overrides are still not consulted. A `span` styled `display:block` is treated as inline. The headless variant would resolve it.
 - A list after a heading is not split into one candidate per item. A list that finishes no sentence within three items is skipped.

+### References are not declarations (2026-10-06)
+
+The node count walked every JSON-LD object, including a bare
+`{"@id": "…#organization"}`. A small marketing site names one Organization as
+both `publisher` and `author` by reference, and the audit reported it as a
+node declared twice. A reference is how linked data avoids a second
+declaration, and it adds no facts. The duplicate count now skips any node
+whose only key, apart from an inherited `@context`, is `@id`. Two full copies
+of one entity still count.
+
+The warn message also named a token count of zero when only a node was
+duplicated. It now names the duplicated nodes in that case.

+### `atom:link` in RSS is read (2026-10-06)
+
+Step 2 of the sketch names `<atom:link rel="self">`, but the gatherer selected
+`link[rel="self"]`. In an XML parse an RSS channel's element is literally
+`atom:link`, so that selector never matched it. A small marketing site whose
+RSS feed carries a correct `atom:link rel="self"` was reported as having no
+self link. The selector also searched the whole document, so an Atom entry's
+own `rel="self"` would have counted as a second feed self link.
+
+Feed links are now read only from the direct children of the Atom `feed` or
+the RSS `channel`. A link counts when it is unprefixed, or its prefix is bound
+to the Atom namespace (`http://www.w3.org/2005/Atom`) under any name. A
+`link` under a prefix bound to another namespace is not read. `rel` is matched
+as a space-separated token list. Response-header precedence is unchanged.

+Two rules now hold for an element whose only signal is a name or a cursor:
+
+- **It holds a control.** An element that contains `a[href]`, `button`,
+  `select`, `textarea`, `summary`, a non-hidden `input`, or any declared
+  `role` is layout around that control, and is not a ghost.
+- **It sits inside a control.** An element inside a link, a button, a
+  `summary` or a widget role is part of that control. A click on it is the
+  control's click.
+
+An inline handler (`onclick` and the rest) is the element's own action. It
+still flags the element whatever it contains or sits in.

+### The label comparison is scoped to controls (2026-10-06)
+
+The sketch compares "an interactive element's aria-label" with its rendered
+text, because an agent clicks by accessible name. The code compared every
+`aria-label`, including landmarks and containers, with all their descendant
+text. A small marketing site's `nav aria-label="Main"`, a

+The overlap and opposing-verb comparisons now run only for native controls
+(`a[href]`, `button`, `summary`, `input`, `select`, `textarea`) and widget
+roles (`button`, `link`, `menuitem*`, `tab`, `option`, `checkbox`, `radio`,
+`switch`, `treeitem`). Every `aria-label` is still read for the instruction

+### FAQPage entries are editorial (2026-10-06)
+
+The JSON-LD fallback counted any `Question` or `Answer` node as visitor
+content. An FAQPage's `mainEntity` questions and their answers are written by
+the site. schema.org's visitor-written form is QAPage. A small marketing site
+that publishes its own FAQ as FAQPage was reported as carrying an unbounded
+visitor-written region.
+
+Questions in an FAQPage's `mainEntity`, with their `acceptedAnswer` and
+`suggestedAnswer`, are now excluded from the fallback. A `Question` or
+`Answer` anywhere else, such as under a QAPage, still counts. A real comment,

+## Implementation deviations
+
+### Not observed is not absent (2026-10-06)
+
+The review above names the false negative: only the sampled pages are
+scanned, so a form at `/support/` fails the site. A small marketing site
+linked "Contact" from its header to a support page with a working form. The
+scan held only the homepage and reported "No contact/lead form".
+
+When no sampled page carries a contact form and no OpenAPI path matches, the
+audit now reads the sampled pages' same-origin links. A link whose path or
+text names a contact page (`contact`, `kontakt`, `support`, `inquiry`,
+`enquiry`, `get in touch`, `reach out`) and that the scan did not fetch makes
+the verdict `notApplicable`. The finding names up to three such links. A
+form there was not observed, so its absence is not established. A site with
+no form and no such link still fails.
+
+Verdicts that moved in the real-page corpus: 18 single-page fixtures fail →
+na, every one a page linking to a contact or support page outside the sample.

 **Counter-evidence:** No vendor doc and no study isolates the effect of list/table markup on LLM answer accuracy — the mechanism is well documented, but the magnitude is not measured in any source located for this dossier. ARIA is an accepted substitute. A div grid carrying role='table', role='row' and role='cell' maps to the same accessibility tree nodes. 'div soup' with correct roles is therefore not penalised by a11y-tree consumers, and an audit that only looks for literal <table> and <ul> tags will produce false positives. Conversely raw-HTML consumers (which the observation-reduction study shows strong models sometimes prefer [observation-reduction-paper]) see the div tags either way. Definition lists (dl/dt/dd) in particular have no documented agent consumer beyond generic role mapping.
 
+## Implementation deviations
+
+### Hidden regions and keycaps (2026-10-06)
+
+The mechanism is list content that collapses into prose when the page becomes
+markdown or an accessibility tree. A small marketing site was flagged for
+same-class rows inside a hidden command palette and a hidden dropdown, and for
+the `kbd` keys of one shortcut. Hidden subtrees reach neither output, and the
+keys of one shortcut are one item.
+
+- Lists and pseudo-lists inside a subtree the markup hides (`hidden`,
+  `aria-hidden="true"`, inline `display:none`, a closed `<dialog>`,
+  `<template>`) are skipped, as chrome is. They no longer count toward the
+  numerator or the denominator.
+- `kbd` children do not count toward the same-class rule.
+
+Verdicts that moved in the real-page corpus: `allbirds-com-collection`
+pass → na, whose only content lists were in hidden panels;
+`gov-uk-vehicle-tax` warn → pass, whose pseudo-list was hidden.

 A page under 512 tokens is `notApplicable`: a retriever never cuts it, so there

+### THIN is reported, not judged (2026-10-06)
+
+Any finding turned the verdict into a warning, so one short card did. A small
+marketing site whose sections all fit the window warned on nine THIN feature
+cards and a newsletter prompt, with the message "Some of this page chunks
+badly". The claimed mechanism is a section the window cuts. A section under
+the window is never cut, and no cited source ties a short section to a lost
+answer. THIN stays in `found` and `details.findings` as information. Only
+SPLIT, ATOMIC-SPLIT and BLOB, or a score under the pass line, now warn.
+
+Verdicts that moved in the real-page corpus, each a page whose only findings
+were THIN: `barclays-co-uk-current-accounts`, `bbc-co-uk-article`,
+`cdc-gov-flu-about`, `cloudflare-com-plans`, `gov-uk-vehicle-tax`,
+`kubernetes-docs-pods`, `otto-de-category`, `stripe-com-pricing`,

 ## Deferred
 
+- **The Evidence list.** It names two Model Context Protocol specification pages
+  (caching, streamable HTTP), which say nothing about chunking. The source the
+  mechanism cites, Azure's published 512-token default and its
+  heading-segmentation advice (S5), is not in the list. The list needs that
+  source restored, verified and stamped before the grade is reviewed.
 - **The real chunker.** Every pipeline splits slightly differently — some on
   tokens, some on sentences, some with overlap. 512 tokens with heading
   boundaries is the common denominator, and the finding survives the variation.

 On the retail page, recall moved from 0 to 0.818, and the page still fails: readability drops the tile headings. Verdicts that moved in the real-page corpus: `atlassian-com-pricing-shell` fail → na, because its only key spans were JSON-LD strings in scripts.
 
+### The article title and hidden panels (2026-10-06)

+Two key-span rules reported facts as lost that no reader loses.
+
+- **An h1 Readability keeps as the title.** Readability removes the first
+  heading that repeats the document title from the article body and returns
+  it as the article title. Every Readability-based pipeline delivers that
+  title. The audit read only the body text, so a page whose h1 repeats its
+  `<title>` lost its h1 to Readability. An h1 span now survives Readability
+  when the article title contains it.
+- **Spans in hidden panels.** Section openers inside a hidden command palette
+  were key spans on a small marketing site. Readability drops hidden subtrees
+  before scoring, and a reader never sees them. Spans inside a subtree the
+  markup hides (`hidden`, `aria-hidden="true"`, inline `display:none`, a
+  closed `<dialog>`, `<template>`) are no longer collected.
+
+Verdicts that moved: the bare-site fixture fail → pass, whose h1 repeats its
+title. In the real-page corpus, `theguardian-com-article` fail → pass (h1 is
+the title), `python-docs-json` fail → warn (h1 is the title),
+`otto-de-category` fail → pass (eight spans in hidden footer panels) and
+`tattly-com-shell` fail → na (its only span sat in a closed dialog).

 The claim is "one identical lastmod equal to the last deploy date". The audit compared lastmod strings exactly. A generator that writes the clock per URL spreads one run over seconds, and exact matching saw every value as different. One large retail site stamped 2451 product URLs between 09:57:16 and 09:57:33 on one day. The audit now counts the largest group of sampled values inside a one-hour window. The 90% share and the 3-day recency rules are unchanged. Values hours apart still count as separate dates.
 
+### `Last-Modified` corroborates but cannot contradict (2026-10-06)
+
+Step 5 of the sketch takes the minimum delta against any page signal, the
+HTTP `Last-Modified` header included. On a static host the header is the
+file's write time, so every deploy moves it. A small marketing site stamps its
+legal pages' `lastmod` from their editorial dates and publishes no
+`dateModified`. Its server sent the deploy day as `Last-Modified`, and the
+audit failed the correct editorial dates as divergent. The audit's own fix
+text tells sites to do exactly what that site did: stamp lastmod from the
+content record and leave it alone on a rebuild.
+
+The header still corroborates: a `lastmod` within seven days of it counts as
+verified. A URL whose only signal is the header, and which disagrees with it,
+now counts as unverifiable rather than divergent. A URL with a JSON-LD date or
+an article meta date is judged as before, against every signal it has.
+
+No corpus or bare-site verdict moved: the corpus fixtures carry no sitemap.

+A false-positive sweep across 44 audits, prompted by two real-site scans. No audit id, grade, tier, weight or result schema changes, but verdicts move on a large share of sites, so scores, saved baselines and dashboards built on 5.x output will shift. Notable moves:
+
+- The 14 crawler audits pass when robots.txt lets a bot inherit the `*` allow, and are not applicable when robots.txt is missing.
+- Optional artifacts that are absent (RSS feed, RSL licence, WebMCP attributes, a full sitemap index read) return not applicable instead of failing.
+- `operability-safety/contact-form` is not applicable when the sampled pages link to a contact page the scan did not fetch.
+- Hidden subtrees (`hidden`, `aria-hidden`, inline `display:none`, closed dialogs) no longer count in fake-headings, semantic-lists, text-fragment and extractor-survival checks.
+- `answer-readiness/text-fragment-addressability` now matches over nearest-block-ancestor runs, as the spec does; a FAQ answer that is present only in unrendered text now fails with that reason.
+
+Each audit's own changeset below lists its change.

 ### Partial sitemap reads decline the verdict (2026-10-06)
 
-The shared sitemap walk keeps at most 500 entries and reads at most 10 child sitemaps. When it stops early, a page missing from the entries it kept may still be listed in the part it skipped. The audit now returns `na` for that case instead of `fail` or `warn`. A page found in the partial read still passes, and a page missing from a complete read still fails.
+The shared sitemap walk keeps at most 500 entries and reads at most 10 child sitemaps. When it stops early, a page missing from the entries it kept may still be listed in the part it skipped. The audit now returns `na` for that case instead of `fail` or `warn`. Unread children of ordinary origin-level indexes also make coverage incomplete. This includes a failed fetch, malformed child, or nested index beyond the walk limit. The guard applies even when the readable portion contains no URLs. A page found in the partial read still passes, and a page missing from a complete read still fails.
 
 The trigger was a large retail site. Its index lists a 2455-URL product sitemap before a one-URL sitemap that holds the homepage. The product file filled the cap, and the audit failed the homepage as unindexed.

 ## Claimed mechanism (falsifiable)
 
-Google states it uses <lastmod> 'if it's consistently and verifiably (for example by comparing to the last modification of the page) accurate'. lastmod is therefore a conditional signal, which engines silently discard on divergence. It is also the only freshness hint a pull-based AI crawler gets from a sitemap. Falsifiable claim: if sampled lastmod values disagree with all available page-level evidence (HTTP Last-Modified, JSON-LD dateModified, article:modified_time) for a material fraction of URLs, the sitemap's freshness channel is inert and re-crawl scheduling degrades to organic rediscovery. Two pathologies are specifically detectable. First, more than 90% of URLs share one identical lastmod equal to the last deploy date. That is a build stamp rather than a content date, and per Google's 'copyright date is not significant' rule it is exactly the disqualifying pattern. Second, a lastmod in the future relative to crawl time, which is always invalid.

Subject: [PATCH 36/36] fix(core): close gaps left by the false-positive review
 fixes

- dom-visibility: share one declaration parser. Drop invalid values as a
  browser does, accept var() as a valid override, and let the nearest
  element that declares visibility decide for notRendered. Readers still
  treat a visibility:hidden subtree as removed, as Readability does.
- css-hidden-ghost-content: use the shared parser for inline markers and
  stylesheet display rules instead of its own regex and blockDisplay copy.
- text-fragment-addressability: judge each element on its own ancestor
  chain, so a visible answer under a hidden wrapper stays addressable.
- ghost-clickable-element-ratio: resolve the first recognised ARIA role,
  case-insensitively; share one role list; count gridcell and scrollbar
  wrappers; exempt observing inline handlers inside a control and flag only
  handlers that stop propagation.
- sitemap gatherer: a child that already failed as a root still marks the
  index scope incomplete.
- sitemap-lastmod-verifiability: a deploy-time Last-Modified header no
  longer vouches for a recent stamp run; those URLs are unverifiable.
