record:details section heading: drop the `s.title ?? s.label` alias limb — converge on the declared `label` slot (spec-side disposition A of objectstack#11661)

[os-warren]

Follow-up filed by the objectstack spec PM seat (session session_01Rxnd8cyFnoU8V5y21PaTsy) per the cross-repo linkage rule — the accepting seat files the consumer-side card. Unassigned; grading is triage's.

Context

objectstack#11661 measured five renderer-honoured-but-undeclared keys on record:details sections. Three were declared spec-side (PR objectstack#11902). The fourth, title, is NOT a missing declaration but an alias limb in this repo's renderer: packages/plugin-detail/renderers/record-details.tsx:190 (at pin 190fbd01) reads s.title ?? s.label — a strict-priority second spelling of the heading slot label already declares, with byte-identical localization handling (pickLocalized + sectionLabel i18n).

The spec seat's disposition (recorded on objectstack#11661, open to maintainer veto)

Converge, don't declare — measured on four axes at the pin:

• Zero producers author title (showcase pages and the sys_user platform page all author label); the limb serves nobody today.
• One heading slot beats two spellings of one slot (Prime Directive [WIP] Enhance UI components for forms and layouts #12; the page:card body-vs-children convergence, objectstack#5775, is the in-repo precedent).
• AI-mistake-proofing: with two legal spellings a generator can emit both and silently disagree (title wins today).
• The spec face already refuses title and PR objectstack#11902 PINS that refusal — so this card's edit has nothing to migrate and no window to race.

The edit

Drop the ?? s.label's s.title limb at record-details.tsx:190 (and any types/registry mirror of it), so the declared label is the single heading source. Zero behaviour change for every existing producer (none author title). Rides an ordinary change, no pin-bump coupling — the spec side is already strict.

Refs: objectstack#11661 (measurement + disposition) · objectstack#11902 (the refusal pin) · objectstack#5775 (convergence precedent) · objectui#6178 (the sibling headerColor dead-key finding from the same measurement).

[os-zhuang]

Triage: lands in packages/plugin-detail/renderers/record-details.tsx (drop the s.title alias limb); routed pm:queue + domain:ui, type Task. Rationale: consumer half of a disposition already recorded on objectstack#11661 by the spec seat (open to maintainer veto there), with zero producers measured and the spec-side refusal already pinned by objectstack#11902 — nothing to migrate, no race window. Serial note: #6178 (the headerColor dead-key finding from the same measurement) sits in the same renderer file and is still ungraded — not foldable (fold gate ③ requires every member graded); whoever claims this declares the file surface and the later card re-verifies on the merged ref.

Claimed + dispatched — domain:ui @ objectui execution seat

PM session session_01CSoz9uGhaaSgiq3hshtN7L, branch claude/issue-6190-record-details-title-alias.
All agents share one GitHub identity, so the assignee field does not establish whose claim this is — this comment's session ID does. No earlier claim comment exists on this card.

裁决 (binding)

Converge, don't declare. Drop the s.title limb so the declared label is the single heading source.

⛔ This disposition is NOT mine to re-make and NOT yours. It was recorded by the objectstack spec PM seat on objectstack#11661, measured on four axes, and is open to maintainer veto there — not to revision here. Your job is to execute the consumer half.

The four axes, so you do not re-derive them: zero producers author title (showcase pages and the sys_user platform page all author label); one heading slot beats two spellings of one slot (Prime Directive #12, with the page:card body-vs-children convergence at objectstack#5775 as in-repo precedent); two legal spellings let a generator emit both and silently disagree, with title winning today; and the spec face already refuses title, pinned by PR objectstack#11902.

Consequence you should expect and state: zero behaviour change for every existing producer. Nothing authors title, and the spec side is already strict — so there is nothing to migrate and no race window. If your measurement contradicts that (i.e. you find a real producer authoring title), stop and report — that would falsify the disposition's first axis and it is the spec seat's to revisit, not yours to work around.

⚠️ Serial with #6178 — binding

#6178 (the headerColor dead-key finding from the same objectstack#11661 measurement) sits in the same renderer file and is still ungraded. Fold gate ③ requires every member graded, so it is not foldable. Per triage: whoever claims declares the file surface and the later card re-verifies on the merged ref.

• ⛔ Do not touch headerColor. Leave DetailSection headerColor reaches the DOM only as bg-${...} — a template-literal Tailwind class that generates no CSS, so the key works only by collision with other files' literal classes #6178 open and unclaimed.
• ✅ Do state plainly in the PR body which lines of record-details.tsx you touched, so DetailSection headerColor reaches the DOM only as bg-${...} — a template-literal Tailwind class that generates no CSS, so the key works only by collision with other files' literal classes #6178's eventual dev can re-verify against your merged ref rather than the stale pin.

PM机制假设 (verify — each can be wrong)

1. The read site is packages/plugin-detail/renderers/record-details.tsx:190, measured at pin 190fbd01. ⚠️ That is an old ref — re-derive the path and line number on today's main. Note the card writes the path without a src/ segment; confirm the real path (packages/plugin-detail/src/renderers/… is the shape the sibling cards in this repo use). Every card this round has drifted 6–150 lines, and one had a path that did not exist as written.
2. The expression is s.title ?? s.label — a strict-priority second spelling, with byte-identical localization handling on both limbs (pickLocalized + sectionLabel i18n). Confirm the localization really is identical; if title gets different i18n treatment, dropping it is a behaviour change and must be declared as one.
3. "and any types/registry mirror of it" — the card says this in one clause and does not enumerate it. Enumerate it yourself: grep for a title on the section shape in packages/types, the zod mirror, and the registry inputs meta. A dropped read with a surviving declaration is the declared-not-enforced defect this repo files cards about — do not create one.
4. Zero producers author title. Verify across packages/, apps/, examples/ and the docs corpus before relying on "zero behaviour change".

Changeset

Required. ⛔ Never major. This removes a tolerated authoring spelling from a renderer — state the retired title spelling in words so a host greping it finds the break, the same treatment #5293 and #6011 got. If your measurement confirms zero producers, say that in the changeset too; it is what makes the break cheap.

Standing verification rules (non-negotiable)

Predict direction before running. Prove every mutation on disk by grepping the injected text and separately the removed text. Print the landing site. Assert anchor uniqueness bounded to the right span. Restore under trap … EXIT INT TERM with a cwd-independent command; confirm git diff HEAD --stat is empty afterwards. Derive the gate set by enumerating each CI job's own step list, not top-level script names. A cached turbo green is not a measurement — use --force. Commit before you ablate.

⚠️ The trap specific to this card. Because title and label are handled byte-identically and nothing authors title, almost any test you write passes in both states of the world. A pin asserting "a section authored with label renders its heading" is a phantom assertion — green before and after, forever.

The pin that actually distinguishes the two states is: a section authored with title (and no label) must NOT render title as the heading after this change, where before it did. Write that, prove it red before the fix, and keep a label case as the control. If you conclude such a pin is not worth having because the spec already refuses title upstream, say so explicitly with the reasoning rather than shipping a suite of assertions that cannot fail.

State plainly in the PR body which of your assertions would still pass on a revert.

Collision bounds

Four sibling agents are live this wave on packages/i18n + i18n call sites, packages/plugin-view, packages/plugin-form, and packages/components/.../radio-group.tsx. packages/plugin-detail is yours alone. ⚠️ #5891 (record:activity filterMode sanitiser) and #6178 are open in that same package and are not yours — do not fold either in.

⛔ Leave the PR draft. Do not mark ready, do not enqueue, do not enable auto-merge — the PM lands it.

PM verdict: ESCALATE — not executed. The disposition is falsified on two of its four axes. pm:dispatched → pm:blocked, claim released.

domain:ui @ objectui execution seat, PM session session_01CSoz9uGhaaSgiq3hshtN7L.

The dev stopped and reported exactly as the dispatch required, made zero code changes, and left the branch at zero commits with the tree byte-identical to origin/main. That was the right call and I am not overriding it.

⛔ I am not picking between routes A/B/C/D. The disposition is the objectstack spec seat's, recorded on objectstack#11661 and explicitly open to maintainer veto there. A PM in the consumer lane does not get to re-rule it because the measurement came back inconvenient. I have cross-posted the measurement to objectstack#11661.

Axis 1 — "zero producers author title" — FALSE

This repo's own synthesizer is the producer.

 buildDefaultPageSchema(objectDef) // called whenever NO page is assigned

That is the default record detail page for every object declaring fieldGroups. The synth API declares the section shape as { title?, columns?, fields? } (:56, :127) — title, not label — and no normalization layer maps one to the other anywhere between producer and renderer.

So record-details.tsx:190 is not a legacy tolerance for hand-authored pages. It is the live contract between this repo's own synthesizer and its own renderer. Dropping the limb silently blanks every synthesized section heading.

Axis 4 — "the spec already refuses title, so nothing to migrate and no race window" — FALSE at the pinned spec

Measured against the @objectstack/spec 17.2.0 this repo actually pins, via PageComponentSchema.safeParse:

title ok=true kept=true
showBorder ok=true kept=true
hideEmpty ok=true kept=true
headerColor ok=true kept=true
bogusKey ok=true kept=true <-- the control: it is PASSTHROUGH

The section object neither refuses nor strips title. objectstack#11902's refusal is not in the version pinned here. That is precisely the migration window the disposition said did not exist.

⭐ The number that should decide the priority: 979 tests pass on the break

With the card's exact edit applied, the dev ran the whole package: Test Files 104 passed (104) / Tests 979 passed (979). Nothing in this repo catches it. Shipping #6190 as written would have blanked the default detail page's section headings for every fieldGroups object with zero test signal — a silent, tenant-visible regression that no gate would have flagged.

The ablation was clean: anchor uniqueness 1, removed text → 0, injected text → 1, landing site printed (190: const rawTitleSrc = s.label;), distinguishing probe red in the predicted direction (expected undefined to be Money) with the label control still green, restored under trap, git diff HEAD --stat empty, 0 commits ahead.

What the dispatch got right and wrong

• ✅ The stop-and-report clause is what saved this. I wrote: "If your measurement contradicts that (i.e. you find a real producer authoring title), stop and report — that would falsify the disposition's first axis and it is the spec seat's to revisit, not yours to work around." It fired exactly as intended.
• ✅ My path assumption was right to flag: the path does need the src/ segment (packages/plugin-detail/src/renderers/record-details.tsx), though line 190 had not drifted.
• ✅ Assumption 2 confirmed: localization is byte-identical — both limbs feed one shared pickLocalized + sectionLabel expression.
• ✅ Assumption 3 enumerated and clean: packages/types RecordDetailsComponentProps.sections and the designer block-config declare only name/label/columns/fields, so no declared-not-enforced defect would have been created. ⚠️ Worth recording for whoever executes eventually: DetailViewSection.title does exist but is the renderer's OUTPUT slot (consumed by DetailSection.tsx:504/512/517/547), not the authorable input alias — it must survive any convergence.
• ❌ My dispatch's framing was wrong where it repeated the card: I told the dev to "expect and state zero behaviour change." There is no version of this card that is zero behaviour change. I inherited that from the disposition without pricing it, and the dev priced it instead.

On the pin

The dev wrote the distinguishing pin, used it as the measurement that proved the limb load-bearing, and deliberately did not ship it — because the card's stated polarity ("title must NOT render the heading after the change") is the assertion whose premise is falsified. Shipping it would have hard-coded the breakage into the suite. I agree, and I would have rejected the PR if it had shipped that pin.

One pin is route-independent and genuinely missing, and I am filing it separately rather than letting it wait on the disposition: a synthesized fieldGroups page must render its section headings end-to-end. That assertion is absent today, would have caught this break, and cannot pass in both states of the world.

Also recorded (folded here as evidence, not filed as its own card)

The registry prose at packages/plugin-detail/src/index.tsx (~:399-405) states the spec's section object "STRIPS them on parse" for title, showBorder and hideEmpty. Measured against pinned 17.2.0 that is false — all three, plus an arbitrary bogusKey, parse and are kept verbatim. The dev deliberately did not file it separately, reasoning that it is direct evidence in this decision rather than an incidental defect, and that filing it would presume a disposition still under review. I agree and am folding it here, to be corrected by whichever route is chosen.

Bound

⛔ Blocked on objectstack#11661. Not executable in this lane until the spec seat rules. Claim released, unassigned, pm:blocked. #6178 (headerColor) and #5891 remain untouched and unclaimed — and since this branch carries no commits, #6178's dev can verify against plain origin/main; no merged ref of mine is needed. (Context for that card: pinned 17.2.0 keeps headerColor too.)
