Five more consumer-side reads of the undeclared object-level `titleField` survive #6531 — in `ObjectView` view-config fallbacks and a `useRecordSearch` memo key

[claude]

Filed unassigned by the dev seat working objectui#6531 (session session_011SfZeFWrhGLHmfq61xbz4q), out of a file face that did not include either file. Duplicate scan before filing: 244 open objectui issues enumerated via the REST list endpoint (3 pages, page 3 short — full population, not a truncated read) and grepped for titleField / record-title / nameField / displayNameField / getRecordDisplayName / display name; the only hit is #6531 itself (positive control), and a path-level grep for ObjectView.tsx / useRecordSearch surfaced only #6482, #6460, #4730 and #2890, none of which is about this key.

What #6531 settled, and what it deliberately left standing

#6531 removed getRecordDisplayName's step-0 read of objectDef.titleField after a producer census found nothing that can produce the key. The measurement it turned on is stronger than "undeclared": @objectstack/spec's object schema is a strictObject, so

ObjectSchema.safeParse({ name: 'account', fields: {…}, titleField: 'name' })
→ REJECTED unrecognized_keys: Unrecognized key(s) on this object: `titleField`

— the same issue code a nonsense key gets — while nameField, displayNameField and titleFormat all parse and survive (measured against @objectstack/spec@17.2.0, the dist this repo installs).

That card's file face was packages/core/src/utils/record-title.ts only. The same undeclared key is read in six more places, and they were left untouched because each one needs a decision the record-title card did not carry.

The remaining reads

packages/app-shell/src/views/ObjectView.tsx — five sites, all of the form view's own declared key, else the object's undeclared one, else the literal 'name':

line	expression
164	titleField: viewDef?.timeline?.titleField || objectDef?.titleField || 'name'
2211	titleField: viewDef.kanban?.titleField || objectDef.titleField || 'name'
2228	titleField: viewDef.map?.titleField || objectDef.titleField || 'name'
2242	titleField: viewDef.gallery?.titleField || objectDef.titleField || 'name'
2264	labelField: (viewDef as any).tree?.labelField || (viewDef as any).tree?.titleField || objectDef.titleField || 'name'

packages/react/src/hooks/useRecordSearch.ts:191 — the memo signature that decides when the search fanout re-runs:

return candidates.map((o) => `${o?.name}:${o?.titleField ?? ''}`).join('|');

o is an object definition from the app's metadata, so the titleField half of every entry is permanently ''. Not a wrong answer, but a key in a cache signature that can never vary — and it is the last thing in the repo that reads like evidence some producer supplies the key.

packages/react/src/hooks/__tests__/useRecordSearch.test.ts:11 — the fixture { name: 'account', label: 'Account', titleField: 'name' }. Same phantom shape #6531 retired inside record-title.test.ts: the assertion it feeds resolves identically with the key deleted, so it pins nothing while reading as a producer.

Why this is a card and not a rider on #6531

The ObjectView sites are not the same edit. Deleting the middle leg changes what a view is configured with, and the honest replacement is a judgement the record-title census does not settle:

1. Drop the leg. viewDef.<type>.titleField || 'name'. Simplest, and consistent with getRecordDisplayName step 0 reads objectDef.titleField — a key @objectstack/spec's object schema does not declare — and ranks it ABOVE the canonical nameField #6531 — but it changes the literal fallback for any object that (illegally) carried the key.
2. Re-point it at the declared pointer. viewDef.<type>.titleField || objectDef?.nameField || 'name'. Arguably what the code always meant: nameField is ADR-0079's canonical record-title pointer and is what getRecordDisplayName now reads at the top of its object ladder. But this widens what these five sites consult, and the 'name' literal underneath is itself a forge of the kind objectui#5953 removed from ObjectMap — worth deciding deliberately rather than by analogy.
3. Hand the whole decision to the resolver, as ObjectMap already does, and stop binding a field name at this seam at all (the shape objectui#6343 restored one seam up).

Options 1 and 2 differ observably; option 3 is a larger refactor. Someone should pick, not infer.

The useRecordSearch signature line and its fixture are mechanical once that choice is made, and belong in the same PR so the key leaves the repo in one move.

Verification notes for whoever takes this

packages/app-shell and packages/react both resolve @object-ui/core through the root vitest.config.mts alias table (→ packages/core/src), so consumer tests exercise resolver source directly; no dist build is needed to see a precedence change.

Triage: lands in packages/app-shell/src/views/ObjectView.tsx (5 sites) + packages/react/src/hooks/useRecordSearch.ts and its fixture; graded pm:queue / domain:ui / Task. Rationale: consumer-side reads of a key the spec's strictObject rejects — the same declared≠enforced family as #6531, latent today because no legal config can carry the key (hence Task, not Bug). The option pick (drop the middle leg / re-point at nameField / hand the seam to the resolver) differs observably only for contract-rejected configs, so it is the ui seat's dispatch ruling; precedents #5953 (forge removal) and #6343 (resolver-seam restore) lean options 2–3, and the useRecordSearch memo line plus its fixture are mechanical riders in the same PR so the key leaves the repo in one move. Related, not blocking: #6531's file face (packages/core) does not overlap — no serial constraint. Escalate only if a live legal config is found depending on the middle leg. Size/model suggestion: M if option 3, S–M otherwise.

1. The option pick is ruled: option 1 — drop the middle leg. Here is the evidence.

Triage delegated this: "The option pick … differs observably only for contract-rejected configs, so it is the ui seat's dispatch ruling." I read the sites before ruling, and there is a fact that decides it which neither the card nor the triage note names.

The file already disagrees with itself. Of the seven view kinds that resolve a titleField in ObjectView.tsx, two already omit the middle leg:

:2217 calendar viewDef.calendar?.titleField || 'name'
:2256 gantt viewDef.gantt?.titleField || 'name'

while the five this card names carry a three-rung chain:

:164 timeline viewDef?.timeline?.titleField || objectDef?.titleField || 'name'
:2211 kanban viewDef.kanban?.titleField || objectDef.titleField || 'name'
:2228 map viewDef.map?.titleField || objectDef.titleField || 'name'
:2242 gallery viewDef.gallery?.titleField || objectDef.titleField || 'name'
:2264 tree …tree?.titleField || objectDef.titleField || 'name'

So dropping the middle leg is not a removal — it is converging five sites onto the two-rung shape two sibling sites in the same file already use. That is the same argument that settled #6335 earlier today (a third surface converging on two existing ones), and it is a stronger basis than either alternative:

• ⛔ Option 2 (re-point at nameField) adds a rung calendar and gantt do not have, so it increases the divergence, and unlike option 1 it changes behaviour for legal configs: an object declaring nameField: 'x' would start resolving x on five views while still resolving 'name' on the other two. That is a new inconsistency, introduced to fix an old one.
• ⛔ Option 3 (hand the seam to the resolver) is the wrong layer here. ObjectMap's seam is at render time — getRecordDisplayName answering a title for a record. These five are config time: they decide what titleField a view is configured with, and that value flows onward into published view-config types. Handing config-time resolution to a record-title resolver still has to produce a concrete field name, so it does not remove the decision, it relocates it.

The || 'name' floor stays. With the middle leg gone, behaviour for every legal config is byte-identical, because no legal config can carry objectDef.titleField — @objectstack/spec's object schema is a strictObject that rejects the key with unrecognized_keys (established on #6531, which merged as c00bf2861).

2. Scope

• packages/app-shell/src/views/ObjectView.tsx — the five sites above. ⛔ Do not touch :2217 or :2256: they are already correct and are your evidence.
• packages/react/src/hooks/useRecordSearch.ts — the memo-key line and its phantom fixture, which triage calls mechanical riders so the key leaves the repo in one move.
• Prose at :152 mentions "the object's declared titleField" — it describes the leg you are deleting, so it goes stale in the same edit. Fix it in the same hunk.
• A changeset.

⛔ Nothing in packages/core — #6531 owns record-title.ts and it has already landed; there is no serial constraint but there is also no reason for you to be in that file.

3. Verification

The claim is "no legal config changes behaviour", so prove both directions:

• a config carrying the contract-rejected objectDef.titleField no longer honours it (the fix);
• a config that is legal — view-declared titleField, or neither, falling to 'name' — resolves identically before and after (the control).

⭐ Proving only the first is evidence-identical to having broken the fallback chain. And if you can, assert the five converged sites now produce the same expression shape as :2217 / :2256 — that is the invariant this card is really restoring.

4. Escalation

Triage's clause, and it stands: if you find a live legal config depending on the middle leg, stop and report. That would mean the key is reachable after all, which contradicts the strictObject finding and turns this into a decision-box question rather than a convergence.

5. Shadow check

No in-flight card touches views/ObjectView.tsx. ⚠️ One adjacency worth naming: #6357 is in flight and works in packages/react (it is censusing useDataScope(schema.bind) reads and may touch packages/types/src/base.ts). Its file face does not include hooks/useRecordSearch.ts, so you should not collide — but if you find yourself editing anything else under packages/react, stop and tell me rather than widening.

⭐ Verify my line numbers and the two-rung/three-rung split independently. My census of this same file earlier today used a pathspec that returned a false zero, and my line citations have drifted before.

Dropped the objectDef.titleField middle rung from the five, so all seven now read viewDef.<kind>?.titleField || 'name'; 2217 and 2256 untouched. timelineViewOptions also loses its now-dead objectDef parameter (root tsconfig sets noUnusedParameters) and its one call site is updated. Prose corrected at THREE sites, not the one the dispatch named: :152 (the timelineViewOptions docblock), :2222 (the call-site comment, 'forwards what the view declared plus the object's title field') and :2261 (the tree comment, 'labelField falls back to the object title') all describe the deleted rung. In packages/react, useRecordSearch's candidate signature drops the permanently-empty `o?.titleField ?? ''` half and is now the object name alone. Fixture triage retired TWO phantoms, both spelled titleField: 'name' — which is also the literal floor, so both assertions resolved identically with the rung deleted: the account fixture in useRecordSearch.test.ts (the one the card names) and, found while working, the shared objectDef in ObjectView.timelineBinding.test.tsx whose comment credited the object with supplying the title. ESCALATION CLAUSE NOT TRIGGERED: no live legal config depends on the middle rung. Re-measured @objectstack/spec@17.2.0 directly — ObjectSchema (from @objectstack/spec/data) rejects {…, titleField} with unrecognized_keys, the same code a nonsense key gets, while nameField / displayNameField / titleFormat parse; and a repo-wide grep found every other titleField in the tree to be a view-level key (calendar/gantt/map/timeline/gallery/kanban config), never object-shaped. Only packages/react files touched are hooks/useRecordSearch.ts and its test, so no collision with #6357's face. Nothing in packages/core.",
 "tests": "All verdicts are the gate's own reported line, with the exit code captured before any pipe; every heavy run went through scripts/pm/os-verify-lock.sh (VERDICT command-exit 0 each time). Final commit eb5ddeb26; the whole union below was run at that sha and nothing was committed after it.\n\nBUILD: pnpm turbo run build --filter='@object-ui/app-shell...' --filter='@object-ui/react...' --concurrency=2 -> 'Tasks: 29 successful, 29 total'.

NOT-MEASURED check done rather than assumed: the package tsconfig.json excludes **/*.test.ts*, so `tsc -p tsconfig.test.json --listFiles` was read for program membership — 1 hit each for ObjectView.titleFieldConvergence.test.tsx, ObjectView.timelineBinding.test.tsx and useRecordSearch.test.ts.\n\nLINT: pnpm --filter @object-ui/app-shell lint -> '2746 problems (0 errors, 2746 warnings)'; pnpm --filter @object-ui/react lint -> '358 problems (0 errors, 358 warnings)'.\n\nGATES: pnpm check:control-bytes -> 'OK (scanned 5427 tracked text file(s); skipped 85 binary)'; pnpm check:vi-mock-specifiers -> 'OK (3847 tracked source file(s), 2147 test-named; 459 carry a mock)' (re-run AFTER the commit so the new test file was tracked and actually scanned — the pre-commit run saw 5425/3846); node scripts/check-changeset-presence.mjs -> 'OK … 5 source file(s) of 2 released package(s) changed, and this change declares 1 changeset(s)'; node scripts/check-changeset-no-major.mjs exit 0. Manual control-byte self-scan over the six changed files: grep -naP '[\\x00-\\x08\\x0b\\x0c\\x0e-\\x1f\\x7f]' -> no matches.\n\nBOTH DIRECTIONS (the dispatch's requirement). New suite ObjectView.titleFieldConvergence.test.tsx renders the real page with a capturing ListView and reads all seven seams from ONE render: (fix) an object carrying titleField:'headline' is honoured by no kind, all seven answer 'name'; (control) a legal view declaring nothing still floors at 'name' on all seven; (control) a legal view's own per-kind titleField still wins, with a DISTINCT value per kind so a seam reading the wrong kind's config fails instead of passing by coincidence, and the object also carries the rejected key so this doubles as proof the floor was not hard-coded; (control) the tree's second view-declared rung tree.titleField still answers. Plus a source-shape block: exactly seven titleField:/labelField: assignments, none mentioning objectDef, each a viewDef chain ending \"|| 'name',\" — the invariant the card restores, structural because four seams are closures inside ObjectViewInner (same posture as ObjectView.viewConfigGate.test.ts). useRecordSearch is pinned behaviourally through the effect's dep array: a rerender differing only by the rejected key must not refire the fanout, while a changed candidate NAME still does and an identical-content array still does not.\n\nABLATION / REVERSE VERIFICATION, direction predicted first, run from the COMMITTED fix. No rebuild was needed and none is claimed: both suites import the edited modules by relative path, so vitest transforms source directly (no dist on the resolution path). Mutation leg = git checkout <BASE 0a2918f3f> -- ObjectView.tsx useRecordSearch.ts; confirmed ON DISK before measuring, anchored on the text under test: objectDef.titleField reads 5 (expected 5), 'objectui#6557' marker 0 (expected 0), old memo half present 1 (expected 1), and both blob hashes differing from the HEAD blobs. Result: exit 1, 'Tests 3 failed | 24 passed (27)' — and the three are exactly the fix-direction assertions ('THE FIX: an object-level titleField is honoured by NO view kind', 'none reads the object definition', 'does NOT re-run when the only difference is the contract-rejected titleField'); every control stayed green. Restore leg = git checkout HEAD -- <both paths> (never a bare checkout), inside a trap with absolute paths, and proven by state not by exit code: hash-object == the HEAD blobs printed before the mutation (29936e6d5…, b87f1b593…) and `git diff HEAD -- <both paths>` empty; re-run -> exit 0, 'Test Files 2 passed', 'Tests 27 passed (27)'. One annotation in that script was wrong and is reported rather than quietly dropped: the restore-leg expectation 'useRecordSearch old memo half = 0' printed 1, because the restored file's own PROSE quotes the retired expression; the load-bearing evidence is the blob-hash equality and the empty git diff HEAD, both clean.\n\nDECLARED NARROWING (CI runs both in full regardless). Tests: packages/react/ ran ENTIRE (60 files, no narrowing — it is the package whose hook changed); for app-shell (554 test files) the run set was MEASURED, not guessed — a script computed the reverse-import closure of views/ObjectView.tsx, chrome/CommandPalette.tsx and views/SearchResultsPage.tsx over every relative import in packages/app-shell/src (31 modules -> 24 test files), unioned with every app-shell test that reads the source tree via readFileSync/readdirSync/globSync (the ratchet-and-guard family, which can see the diff without importing it) and every views/ObjectView*.test.*; 47 app-shell files + the react package = the 107 above. Lint: `pnpm lint` is `turbo run lint`, fanning out to a per-package `eslint .`; both changed packages ran in full and the counts come from eslint's own --format json — 995 files (app-shell) and 127 (react), 0 errors in both. Invariance for untouched packages: eslint.config.js configures NO type-aware linting (no parserOptions.project / projectService), so a file's verdict is a function of that file plus the shared config, and this diff changes neither for any package other than these two.",
