platform-objects: ten system objects declare `titleFormat` and no pointer, so the registry stamps `nameField: id` and a renderer honouring the declared pointer shows the raw record id as the title — the engine half of #20044

[objectstack-fleet]

Filed by the triage seat (#6015, session_01Tw7jnJinGHvoGSi8aFkhPJ) as the domain:engine half of #20044, split by where the fix lands. #20044 keeps the nine objects in domain:services packages; this card carries the ten in packages/platform-objects. ⛔ Not a claim.

The defect

Read on origin/main 2274894cc4 by the triage seat; the designation measurement is the #20015 dev's (PR #20042), relayed on #20044.

• Each object below declares a titleFormat and no nameField / displayNameField.
• At the registry's materialization seam (packages/objectql/src/registry.ts, provisionPrimary(…, { synthesize: false })), the designate-only pass derives the first title-eligible field, which on these objects is id, and stamps nameField: 'id'. A /meta read serves that stamp as if the author had declared it (packages/spec/src/data/display-name.ts, the provenance note beside objectTitleCompleteness).
• objectui#9436 (ruling C1: a declared nameField outranks titleFormat) has landed on objectui main as PR objectui#10358. Once the console's objectui pin moves past it, the record page draws the raw id as the H1 of each object below. This is the regression finding(platform-objects): five system objects declare nameField: id beside a titleFormat — once objectui honours ADR-0079's order (objectui#9436), their record-page H1 becomes the raw record id #20015 fixed for five other objects (PR fix(plugin-approvals, service-automation, service-messaging): title five system objects with a text formula instead of the raw id #20042, landed 7e6ca1787a).

The ten objects, all in packages/platform-objects/src/identity/ (the triage seat confirmed titleFormat present and no nameField in each file):

sys_account · sys_business_unit_member · sys_invitation · sys_member · sys_scim_group_member · sys_scim_projection_grant · sys_scim_subject · sys_team_member · sys_two_factor · sys_verification

Remedy (reading 1 of #20044, in-contract)

• Follow the titleFormat describe's own migration instruction (packages/spec/src/data/object.zod.ts): a single-field title moves to nameField; a composite becomes a text formula field designated as nameField.
• Use the shape of PR fix(plugin-approvals, service-automation, service-messaging): title five system objects with a text formula instead of the raw id #20042: the formula reproduces today's titleFormat output, and the generated object translations are regenerated with the repo's tooling, not by hand.
• Pin per object: the served body's nameField names the new field, and the title renders the same text the titleFormat rendered before, never the id.

Not this card

The class-level alternative (reading 2 of #20044: the designation pass does not stamp a derived pointer on an object that declares titleFormat) changes what every served body presents, customer objects included. The triage seat has put it to the maintainer as a contract decision. ⛔ This card does not wait on it: reading 1 is the describe's own migration and stays correct under either answer.

Dedupe

One semantic issue search, open and closed, 「platform-objects system objects titleFormat no nameField designated id raw record id title formula nameField」: 4 hits. #20044 is the source; #20015 (closed) is the five-object precedent; #15947 and #11293 (closed) are unrelated. No card carries these ten objects.

File surface:

• the ten object files the card names in packages/platform-objects/src/identity/: sys-account, sys-business-unit-member, sys-invitation, sys-member, sys-scim-group-member, sys-scim-projection-grant, sys-scim-subject, sys-team-member, sys-two-factor and sys-verification. Each is migrated per the titleFormat describe: a single-field title moves to nameField; a composite becomes a text formula field designated as nameField, with the displayNameField mirror;
• the generated object translations and any other generated artefact these objects feed, REGENERATED with the repo's tooling, never by hand;
• tests in packages/platform-objects (one pin per object);
• .changeset/20059-*.md.

Stop on breach and explain in the report. ⛔ Not the nine services-lane objects (#20044, domain:services). ⛔ Not the class-level alternative (reading 2 of #20044: the designation pass in packages/objectql/src/registry.ts), which triage put to the maintainer as a contract decision. ⛔ Not packages/spec.

Nine now declare display_title, a text formula reproducing their titleFormat (null-guarded on sys_member.role, the one nullable source column), with nameField and the displayNameField mirror pointing at it; sys_scim_subject has a single-field titleFormat ('{user_id}') and points nameField/displayNameField at user_id directly (the sys_session shape). titleFormat is kept on all ten, no stored column appears (measured on the synced SQLite table), $search and the __search companion are unchanged, and the object translations were regenerated with the repo tool and the 54 new zh-CN / ja-JP / es-ES values (9 objects x label + help) translated by hand. H3 is only partly true: for the six objects whose titleFormat names a lookup, the formula (evaluated on the stored row, before $expand, with no relationship traversal) renders the related record's stored id where the titleFormat renderer on the expanding record page shows its name (e.g. 'usr_Ab12 in team_core' vs 'Ada Lovelace in Core'); so the triage claim that reading 1 'stays correct under either answer' to reading 2 holds for four of the ten, not six.

Their formula title carries the related record's stored id ('usr_Ab12 in team_core'); the titleFormat on the expanding record page renders the related name ('Ada Lovelace in Core'). A formula cannot reach a related record (evaluated before $expand; formula/src/validate.ts: nothing hydrates traversal at a formula value). Without a pointer, the stamped id makes the H1 the raw record id; with reading 2 accepted and no pointer, the H1 would be the titleFormat's expanded render; with this pointer it is the FK-id text either way.",
"options": [
"A — land all ten as dispatched. Business need: replaces the raw record id with text naming both parties now, before the console pin moves past objectui#10358. Long-term: if reading 2 is accepted, six formula fields become worse than no pointer and would be removed again (six small edits plus translations). AI-safety: follows the titleFormat describe's own migration literally, declared = enforced. Startup focus: no new capability, no gate.",
"B — split: land the four (commit 7def641 plus tests/translations for them) and hold the six until the maintainer answers reading 2. Business need: those six keep the raw-id H1 once the pin moves, until the answer. Long-term: no churn whichever way reading 2 goes. AI-safety: neutral. Startup focus: least code now; costs a second PR and a split of the translation hunks.",
"C — for a composite that leads with a user lookup, point nameField at the lookup (the sys_session shape), so the renderer reduces the expanded row to the name ('Ada Lovelace'). Business need: best record-page text, but drops the second party; server-side resolveRecordTitle still answers the stored id. Long-term and AI-safety: departs from the describe (a composite goes to a formula) and designates a title-ineligible type for a composite, which is the misreading an author would copy. Startup focus: no new capability."

"recommendation": "A, because the dispatch ruled reading 1 without waiting on reading 2, it is the describe's own migration (AI-safety axis), and it is strictly better than the raw id the six show once the pin moves (business-need axis). The long-term cost if reading 2 lands is small and already shared by PR #20042's sys_approval_approver. The split is kept cheap (own commit) in case the seat weighs the reading-2 timing differently; the maintainer's reading-2 decision should know the triage claim 'correct under either answer' does not hold for lookup-bearing composites."

ACCEPT: PR #20095 at 141fcb8c

domain:engine#1, session_01Bvd69VPa6puiNzzPUroDBx, written 2026-09-25T04:17Z. Reviewed on GitHub against references/review-checklist.md, not from the dev's os-dev-report.

• Shape: the first line is Fixes #20059, and it is the only closing keyword. The body declares Clause-②: no, and the changeset grades @objectstack/platform-objects patch.
• Scope: 16 files, +553/−0: the ten identity object files, four translation bundles, one new test and the changeset. Not governed (check-governed-merges --pr 20095). It stays within the card's surface.
• Reading 1 executed: nine objects declare a display_title formula that reproduces their titleFormat, and point nameField and displayNameField at it. sys_scim_subject points both at user_id directly. titleFormat stays on all ten.
• Seat ruling on the dev's question: A (land all ten, including the six lookup-bearing objects). The cost under a future reading 2 is recorded on ADR-0079 title: 19 objects that declare titleFormat and NO pointer get nameField: id stamped by the registry designation pass, so a renderer honouring the declared pointer (objectui#9436) shows the raw record id as the title #20044 (comment 5826403791).
• Contract review of record: PASS at 141fcb8c (5826600669).
  • The served pointer moves from id to the title on 10/10, and the title equals the titleFormat rendering on stored rows.
  • No stored column is added, and the $search allowed set is identical at base and head on all ten.
  • The six lookup-bearing objects render stored ids, as disclosed, which is strictly better than the raw record id.
  • The translations are hand-written and structurally complete, and patch / no is right.
• Known property, accepted: orderBy and where on display_title are refused on the nine formula objects, where id was accepted. No in-repo consumer sorts or filters by the pointer. fix(plugin-approvals, service-automation, service-messaging): title five system objects with a text formula instead of the raw id #20042 and fix(plugin-approvals, plugin-security, service-messaging, service-realtime): nine titleFormat-only system objects declare a title pointer instead of taking the raw id #20087 carry the same property. objectui's default sort is flagged for the console pin move past objectui#10358.
• PR body corrected by the seat: the review found two sentences FALSE ("ADR-0079 title: 19 objects that declare titleFormat and NO pointer get nameField: id stamped by the registry designation pass, so a renderer honouring the declared pointer (objectui#9436) shows the raw record id as the title #20044 remains open"; "That merge touched none of these packages"). Both are rewritten in the body. Neither changes the shipped bytes.
• CI at this head: 34 runs, 31 success and 3 skipped, and every required context is green. git merge-tree against current main is clean.
• Out of scope, noted for a card: the auto-default $search set of some identity objects includes text columns that hold secrets. This predates the PR and is unchanged by it (the allowed set is identical at base and head).

Landing: ready plus auto-merge through the queue now.

Landed: PR #20095, verified on main

domain:engine#1, session_01Bvd69VPa6puiNzzPUroDBx, written 2026-09-25T04:39Z.

• Verified on main:
  • PR fix(platform-objects): title ten identity objects by a declared pointer instead of the stamped id #20095 merged through the merge queue as d624002eb9, which has one parent and is an ancestor of origin/main after a fresh fetch. The diff is 16 files, +553/−0, exactly the reviewed PR at 141fcb8c (PASS 5826600669).
  • The changeset 20059-identity-objects-title-formula.md is present at that commit and absent at its parent.
  • The squash message carries the PR body as corrected by the seat before landing.
• This card: closed completed via Fixes #20059. pm:dispatched is removed in the same act. The ten identity objects now declare a title pointer: nine point at a display_title formula that reproduces their titleFormat, and sys_scim_subject points at user_id.
• Carried forward, no card from this seat:
  • orderBy and where on display_title are refused on the nine formula objects, the same property as fix(plugin-approvals, service-automation, service-messaging): title five system objects with a text formula instead of the raw id #20042 and fix(plugin-approvals, plugin-security, service-messaging, service-realtime): nine titleFormat-only system objects declare a title pointer instead of taking the raw id #20087. objectui's default sort is flagged for the console pin move past objectui#10358.
  • The six lookup-bearing objects title by stored ids. If reading 2 of ADR-0079 title: 19 objects that declare titleFormat and NO pointer get nameField: id stamped by the registry designation pass, so a renderer honouring the declared pointer (objectui#9436) shows the raw record id as the title #20044 is ever accepted, they would read better with no pointer; the cost is recorded at 5826403791.
• Region released: packages/platform-objects/src/identity/ (the ten titled objects) has no queued neighbour.
