… fetch Response Generated from spec (Fetch/DOM Living Standards quoted verbatim; BCD has no entry yet — interim table labelled as such; showcase demo embedded, routes verified 200).

Generated from spec PRs (whatwg/html#11536, w3c/pointerevents#460 diffs quoted verbatim; both still open — warn-block says so). No showcase demo yet (route 404) — text-link fallback, recorded as follow-up goal.

… properties (in-place, 5133099851317248) In-place upgrade justified by the durable-demo contract's factual-error clause: the old lede/example claimed getComputedStyle().borderWidth returns the authored width post-147; css-backgrounds-3 explicitly makes border-width's resolved value the USED value (0px with border-style none|hidden) — only outline-width/column-rule-width readbacks change. Corrected with the spec clause quoted. Adds Baseline banner, verbatim grammar Syntax section, real BCD + interim compat tables, showcase iframe (routes GET-verified 200).

Generated from spec (css-overflow-5 propdef + mode/activation sections quoted verbatim; CSSWG PR #13627 merged, issue #12122 open — warn-block says so). Child routes for the links and tabs mode keywords. BCD has no mode subfeatures — interim table labelled as such. Showcase mode-switcher demo embedded (routes GET-verified 200).

…place, 6242687411945472) Additive upgrade per the weekly hardening routine: Baseline banner (no web-features entry — stated with sources), verbatim Document-Policy ABNF + derivation rules, interim compat table (BCD has no header entry — stated), showcase worker-feature-probe demo embedded (routes GET-verified 200), exact flag steps in warn-block. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01DoHz1w2nU95PrgRi2o6Kka
In-place upgrade justified by the durable-demo contract's factual-error clause: the old page said the autofill event fires on form controls after autofill completes; the WICG spec dispatches it at the Document before values are committed (sections 4.1/4.3, IDL quoted verbatim). Adds Baseline banner, verbatim IDL Syntax section with child routes (constructor, full-address token, WebDriver BiDi autofill.trigger), real BCD compat table, showcase refill-flow demo embedded (routes GET-verified 200).

- Fix spec fragment identifiers to the WICG spec's real anchors across all four pages (verified against the live document's id set), including three broken fragments the review did not flag (#intro, #html-integration, #autofill-value-entry). - .warn-block strong: amber-on-paper was 3.58:1 at 0.75rem (below WCAG AA 4.5:1); now var(--text-charcoal), amber border kept — on the overview page too, which had the same issue. - Constructor page: correct the trust description — synthetic dispatchEvent() events carry isTrusted === false, so sources are distinguishable at the trust level; the shared structure is what makes one listener suffice. - full-address example: complete consumer that inserts labelled state/ZIP controls with autocomplete tokens and calls refill() only after changing the form.

…verlapping pages The 2026-10-04 weekly run (PR #12) independently rebuilt four pages this PR also carried (v154 scroll-marker-group-modes incl. new links/tabs child routes, v154 fetch abort-reason forwarding, v147 width/style decoupling, v147 document-policy-in-dedicated-workers). Those are published on main, so this merge resolves every conflict in main's favor — the fetch-api conformance suite was byte-identical on both sides. This PR's remaining net content is the v147 js-profiling-in-dedicated-workers MDN-shape upgrade (untouched by main), its lifecycle records (responsive-support ok record restored after taking main's file, goals re-rolled), and a reports regen to follow. check-routes, validate-artifacts, deno fmt --check and deno check server.ts green on the merged tree.

Weekly depth run (2026-10-04). Channels at run time: stable=155 (cuts Oct 6), beta=156, dev=157 — so v154 is what most users run. Coverage gap found: 77 missing pages across v154–v157; 159/198 existing pages still pre-MDN-shape. This batch:
