   Dispatch order — domain:ui seat, PM session session_011SfZeFWrhGLHmfq61xbz4q. Branch: claude/issue-6531-titlefield-producer-census. Assignee set by the PM (objectstack#12520).

   Triage's ruling, verbatim — the census is the work, and the fork is real

   The census the card names is the work, and it is dispatchable as-is with a premise-first fork: (1) run the producer census — which code paths, if any, put titleField on an object-shaped payload handed to getRecordDisplayName (the card already measured zero object-level occurrences in both repos' metadata, with positive controls; the remaining population is fetched/derived shapes, e.g. the lookup-chip and search-candidate paths the NAME_ISH_RECORD_KEYS docblock cites); (2) census says zero producers → remove the step-0 objectDef.titleField read, making declared nameField the top of the ladder as ADR-0079 states — a lenient consumer-side alias for a key no producer declares is exactly the shape Commandment #0.1 bans; (3) census finds a real producer → stop and report: the choice then lies between declaring the key in the spec (a contract expansion, maintainer territory via domain:spec) and re-ranking it below nameField, and neither may be picked in passing. ⛔ Do not change the precedence order speculatively while the read stays — order and existence travel together through the fork.

   Coming back with a census and no code is a success on this card. Branch (3) is an acceptable ending, and it routes to domain:spec or the maintainer — not to you.

   ⭐ That last sentence is the sharpest fence on the card: order and existence travel together. Re-ranking titleField below nameField while leaving the read in place would look like a safe half-measure and would actually be the worst outcome — it keeps a consumer-side alias for an undeclared key and silently changes precedence, so neither the removal nor the contract question ever gets decided.

   Where this card comes from, and why the fence is drawn there

   This is the finding #6343's dev filed out of a file it was fenced out of. That card removed InterfaceListPage's derived titleField binding after measuring zero consumers; while doing so it read record-title.ts and found that step 0 consults objectDef.titleField — a key @objectstack/spec's object schema does not declare — and ranks it above the canonical nameField.

   I could not verify the spec half from this checkout (the spec dist is not installed here), so treat it as the card's measurement, not as established. Re-derive it in your worktree. If the spec does declare titleField after all, the premise collapses and that is a finding — report it before writing anything.

   What I did verify on origin/main: packages/core/src/utils/record-title.ts:388 reads

   valueAt(record, options?.titleField) ?? valueAt(record, objectDef?.titleField)

   so the step-0 consultation is real and is above the nameField rungs.

   The census must carry positive controls

   A zero-producer result is the whole basis for branch (2). ⛔ It does not count until a term you know is present in the same search space fires — the card's own precedent is that nameField and locationField were used as controls for exactly this kind of sweep. The remaining population triage names is fetched/derived shapes (the lookup-chip and search-candidate paths cited in the NAME_ISH_RECORD_KEYS docblock), which is where an object-shaped payload could acquire the key without any metadata file declaring it — search there, not only in metadata.

   File face

   packages/core/src/utils/record-title.ts and packages/core/src/utils/__tests__/record-title.test.ts, plus a changeset if you land code. The census itself may read anywhere.

   ⛔ packages/spec is not yours. If the answer is "declare the key", that is domain:spec and maintainer territory — report, do not reach for it.

   In-flight, do not touch

   #6538 (views/metadata-admin/, currently red on a ratchet) · #6551 (app-shell/providers/expressionUser.ts) · #6548 (packages/core/src/actions/__tests__/) · #6537 (examples/schema-catalog). Note #6548 is also in packages/core but in a different subtree — measured disjoint.

   If you land the removal, reverse verification required: a pin written first that fails while step 0 still reads the undeclared key, and mutation proven on disk rather than inferred from an exit code.

   Claim — domain:ui dev seat, session session_011SfZeFWrhGLHmfq61xbz4q (dispatched by the PM order above; same session, dev subagent seat). Branch: claude/issue-6531-titlefield-producer-census.

   Starting the premise-first fork: re-derive the spec half (does @objectstack/spec's object schema declare titleField?) in a fresh worktree with the dist actually installed, then run the producer census over fetched/derived shapes with positive controls. Will report the census before writing any code.

     "summary": "The census came back ZERO producers, and the premise re-derived STRONGER than the card stated: @objectstack/spec's object schema is not merely silent on titleField, it REJECTS it. Measured against @objectstack/spec@17.2.0 (the dist this repo resolves), ObjectSchema.safeParse({name,fields,titleField:'name'}) fails with `unrecognized_keys` — the same issue code a nonsense key gets — while nameField/displayNameField/titleFormat all parse and survive; ObjectSchemaBase is a strictObject (object.zod.ts:1540). So branch (2) of the fork: removed the step-0 `objectDef.titleField` leg from getRecordDisplayName, making the declared nameField the top of the object ladder per ADR-0079. Order and existence travelled together as the card required — precedence was not touched independently. The DECLARED half of step 0 (options.titleField, a real key on all six ui/*Config view schemas) is untouched and pinned by a CONTROL test green in both ablation legs. Also updated the three docblocks that described the old ladder, including the NAME_ISH_RECORD_KEYS parenthetical ('search candidates that carry only name/titleField') that was the strongest-looking evidence for reading 2 and the one claim that did not survive contact with the code.",

Selection derived, not guessed: every test file in the repo was scanned for a fixture pairing titleField with an object-def pointer (nameField/displayNameField/titleFormat); exactly four matched, three outside packages/core, all run.\n· @object-ui/core lint (the package's own CI command, complete): '✖ 513 problems (0 errors, 513 warnings)', EXIT_core_lint=0.

Mutation proven on disk by content hash and anchored greps in BOTH directions, never by an exit code: HEAD blob c91fd4db922eb10c87064d2e7eac029a9eea4f27 == pre-mutation hash; post-mutation injected-text count=1, removed-text count=0, hash moved to 4a2a2cb0dea9044b2dfca9e23e000851113330e2 ('MUTATION CONFIRMED ON DISK'). Ablated run: 3 pins red ('expected \\'Undeclared Alias\\' to be \\'Canonical Name\\'' etc), 'Tests 3 failed | 72 passed (75)'. Expected direction was plain red and that is what it did. Restore leg given the SAME treatment: git checkout HEAD -- <abs path> (never a bare `git checkout --`, which reads the possibly-polluted index), hash back to c91fd4db..., git diff HEAD empty ('RESTORE CONFIRMED'), so no later measurement ran on a mutated tree. Script carried trap '<restore>' EXIT INT TERM with an absolute REPO_ROOT.\nNO REBUILD PARTICIPATES AND THAT IS CORRECT HERE: root vitest.config.mts aliases @object-ui/core to packages/core/src, so every test — mine and every consumer's — exercises resolver SOURCE. A dist-based ablation in this repo would measure nothing.\nONE OF MY OWN PINS WAS WRONG FIRST, reported rather than quietly re-run: the 'only pointer' case initially used legacy_title and stayed red after the removal. The fixture was at fault, not the code — step 4b(ii)'s *_title affix rung answers legacy_title on its own.

    Post-merge verification on main (domain:ui seat, session session_011SfZeFWrhGLHmfq61xbz4q). PR #6560 landed as c00bf2861.

    1. The object-level read is gone, the view-level one survives. This is the whole point of the card and both halves are measured, not one:

    • valueAt(record, objectDef?.titleField) → 0 occurrences;
    • valueAt(record, options?.titleField) → 1, untouched.

    The same key name stays declared on all six view configs and rejected on objects. That asymmetry is what made this a declared-equals-enforced restoration rather than a breaking removal, and it survived the queue intact.

    2. The CONTROL pin is on main — the case asserting the declared view-level options.titleField still wins at step 0. That is the assertion that stops the removal over-reaching, and it would be the first casualty of a careless follow-up.

    3. The phantom pin is retired. ⚠️ Worth recording how I nearly mis-called this: a bare count of the old pin name "honors objectDef.titleField when set" returns 1, not 0, which reads as "the retired pin is still there." It is not. The single hit is at record-title.test.ts:149, inside the comment that explains why the pin was retired — no it() carries that name.

    That is my catalogued failure ⑥ — a string hit is not the claim — and it is the second time today it has nearly produced a false alarm from this seat. The claim is "no test is named that"; a comment quoting the old name matches the same bytes. The surviving string is the record of the retirement, which is exactly what should survive: without it, the next editor re-adds a fixture whose green means nothing.

    Card closed as completed.
