docs(guide): resolve four react-pages.md contradictions toward the framework's sources

[os-support-ai]

Fixes #5413

The guide is live material — @object-ui/react-runtime's README links it twice
(README.md:19 and :127) — so each contradiction was reachable teaching.

Every claim was re-measured, not inherited. The card measured against
objectstack@502dc6fe7; that pin had moved 65 commits by the time this ran. All four
were re-measured against objectstack@f094214b3 and objectui 77f846a8b. Nothing had
been fixed upstream in the meantime, so no axis is moot — but three of the card's
citations had drifted, noted below.

Per-axis verdict

All four came out settled, each by a live shipped mechanism rather than by an ADR
whose status could be argued. Nothing goes to the decision inbox.

#	Axis	Verdict	What changed in the guide	Source read
1	Tailwind styling	settled	Dropped "+ Tailwind" from the kind table and the html-tier blurb; restyled the headline example to an inline style object; replaced the "so use Tailwind" conclusion on the layout-containers paragraph; added a Styling section giving the mechanism and the per-tier primitive	packages/lint/src/validate-page-source-styling.ts — rule page-source-className-tailwind, fires on kind html/react/jsx, hint names inline style + hsl(var(--token)) for react and structured props + JSON style for html. Registered in authoring-rules.ts:741 (tier: 'advisory'), exported from lint/src/index.ts:152, released in @objectstack/lint@11.5.0 (changelog ec7175d, which states it "corrects … ADR-0080/0081 away from the 'HTML + Tailwind' framing"). Backed by ADR-0065 (Accepted 2026-06-22) and ADR-0080's 2026-06-30 header amendment
2	record:* scope	settled	Kept the tag-derivation rule (it is accurate); added the exclusion, the real os validate error text, the per-block alternatives table, and the note that the rule matches by type so Block type="record:…" is caught too	packages/spec/src/ui/react-blocks.ts — the REACT_RECORD_BLOCK_ALTERNATIVES ledger and the withdrawal rationale (#4413); packages/lint/src/validate-react-page-props.ts:913 — REACT_BLOCK_NEEDS_RECORD_CONTEXT, severity error, matched by type not by tag list
3	adapter.find options	settled	filters: → $filter; added the load-bearing-$ note with the exact key list	objectui packages/types/src/data.ts:42 — QueryParams declares only $-prefixed keys; packages/data-objectstack/src/index.ts:2976 convertQueryParams builds a fresh options object from $-prefixed reads only, so an unprefixed key reaches no branch. The framework's own react page uses $filter (renewals-pipeline.page.ts:67)
4	Block inventory	settled	Split the single tag list into runtime scope vs authored contract, named react-blocks.md as the prop authority, and moved the flat-props example off two deprecated ObjectGrid spellings	REACT_BLOCKS in packages/spec/src/ui/react-blocks.ts is exactly ObjectForm, ListView, ObjectChart, Block; objectui packages/core/src/registry/public-blocks.ts PUBLIC_BLOCKS plus buildComponentScope (renderers/layout/react-page.tsx:66, `if (!tag

Why axis 1 is settled rather than escalated

This is the one the card framed as an ADR-amendment question, so it got the most scrutiny.
The amendment lives in ADR-0080, whose own Status line still reads "Proposed" — but the
amendment is a correction pointing back to ADR-0065, which is Accepted, and it has
since been implemented and released: a dedicated lint rule ships and is wired into
os validate/os build, the generated react contract carries it, and objectstack#10286 /
PR #10436 has just carried the same correction into PageSchema's own describes. That
card's needs:contract-review label is a path-limb process gate on packages/spec/src/**,
and its reviewer graded the content limb "no" — it is not a dispute about direction.
Nothing anywhere in either tree argues the other way.

Three of the card's citations had drifted — corrected here

• The card cites packages/lint/src/validate-responsive-styles.ts (style-classname-tailwind)
  as the Tailwind corroborator. Counter-probed: that rule never reads page source —
  it walks regions[].components[] only, and the file contains no occurrence of source
  at all. The rule that actually governs the source tier is the separate
  validate-page-source-styling.ts cited above. Same conclusion, stronger and correct
  authority.
• The card locates QueryParams at packages/types/src/data.ts in the framework repo.
  That path does not exist at objectstack@f094214b3; the file is objectui's own.
• The card says the record:* gate applies to the four withdrawn tags. It matches by
  type prefix, so all record:* blocks are covered — including the six never in the
  contract — and Block type="record:…" with the type spelled out.

One bounded in-place fix, declared

The Live data sample had a second defect in the same call, same class (the sample
contradicts ObjectStackAdapter's real contract): it passed the result straight to
setRows and then called .map on it. find resolves to a QueryResult
({ data, total, page, pageSize, hasMore }), never a bare array — normalizeQueryResult
(data-objectstack/src/index.ts) returns that shape on every branch, and find is
declared as returning a promise of QueryResult (generic elided here — GitHub's sanitizer
eats angle brackets). As written the sample throws. Corrected to res.data alongside the
$filter fix and called out in the prose, rather than left as a silent rider. Same file,
same defect class, same gate family, no new verification surface.

Verification

All results below are on the final commit 42a1d7359, re-run after committing; exit
codes captured per gate, never through a pipe.

EXIT=0 :: check-doc-component-types.mjs :: Every documented component type is registered.
             (183 doc files, 1054 code blocks, 887 `type` literals, 742 registered / 145 exempted)
EXIT=0 :: check-doc-links.mjs           :: Links are valid across 13 scan roots.
EXIT=0 :: check-control-bytes.mjs       :: OK (scanned 4521 tracked text files; skipped 85 binary)
EXIT=0 :: check-changeset-presence.mjs  :: No source of a released package changed in this range
EXIT=0 :: check-changeset-no-major.mjs  :: No changeset declares a `major` bump

Plus the standing control-byte self-scan on the changed files
(grep -naP '[\x00-\x08\x0b\x0c\x0e-\x1f\x7f]') — clean.

One gate narrowed, declared not skipped. check:doc-snippets compiles every ts/tsx
fence in a covered document against built dist/*.d.ts, and react-pages.md is covered
(not in UNGATED_DOCS). Its only input from this file is one tsx fence, and that fence is
byte-identical before and after — extracted and compared programmatically, 1 fence
before, 1 after, IDENTICAL: True — with its doc-snippet: fragment marker still
immediately above it. The gate's verdict on this file therefore cannot move, and CI runs it
on a built tree regardless. No ablation was run: nothing here is a gate-can-fail claim.

No test was skipped, disabled, or quarantined. content/docs/utilities/index.md was not
touched (sibling card #5360 is in flight there); content/docs/releases/ untouched; no
force-push.

Changeset

Empty frontmatter — docs-only, so this publishes nothing, declared explicitly rather than
left undeclared (objectui does not use a skip-changeset label). check-changeset-presence
confirms none is owed.

Out-of-scope findings, filed not fixed

• Three objectui sources still teach the "HTML + Tailwind" page-source framing ADR-0080's amendment retracted — one of them is a published TSDoc on PageSchema.kind #5461 (objectui, unassigned) — three objectui sources still carry the same retracted
  "HTML + Tailwind" framing, one of them the published TSDoc on PageSchema.kind
  (packages/types/src/layout.ts:616), which links this guide and so will contradict it
  once this lands. Outside this card's declared file surface.
• objectstack#10479 (unassigned, filed as a sub-issue of objectstack#10288) — the
  showcase CRM workbench react page passes limit: 200 to adapter.find, the same
  dropped-option class, in a second file that finding(react): SchemaRenderer's properties / props loops collapse ANY object value that carries a string source key to that string, so bodyExtra: { source: "web", campaign: "spring" } reaches the runner as "web" #10288's stated one-file change does not
  reach.
