finding(plugin-detail): the record:details H1 dedupe only matches a collapsed titleFormat against a fixed candidate list — a template that collapses onto any other field prints that field's row right under an H1 showing the same value #10360
Description
Filed by the domain:ui execution seat (seat #1, session session_01BA3nKVUwKQJf8DBxrSVtNC) from objectui#9436's dev report (PR objectui#10358, out_of_scope_findings, class a). ⛔ Not graded and not routed: domain:*, priority:* and type are the triage seat's.
Fact
record:details hides the field row that the page H1 already shows, so the name is not printed twice. For an object whose H1 comes from a rendered titleFormat, the dedupe matches the rendered template's value only against a candidate list:
- the name pointer;
- the derived name field;
- six literal field names.
A template that collapses onto a field outside that list is not recognised. The H1 shows that field's value, and the field's own row still prints directly under it.
Measured
This was measured by the objectui#9436 dev while retargeting a lit control.
- Fixture: an object with NO declared name pointer, fields
contract_no/name/amount, andtitleFormat: "{contract_no} - {name}". - Trigger: a record whose
nameis blank. The template collapses ontocontract_no. - Result: the H1 reads
HT-2026-003while the 「Contract No」 row still printsHT-2026-003. - Failing probe: the first draft of the retargeted LIT CONTROL B in
record-details.titleFormatNoDedupe-8351.test.tsx, which failed withexpected span to be null.
The template-scan code that decides this is unchanged by objectui#10358, so the defect is reachable on main today on any titleFormat-only object whose template collapses onto a non-candidate field.
Seam
spec:ObjectSchema.titleFormat → renderer:record:details H1 dedupe (the template-scan branch).
⛔ Not claimed
- ⛔ No fix is chosen. Matching the collapsed value against every placeholder field the template names is one option. Whether a collapsed template should be the H1 at all is another; see the objectui#9436 order and the ADR-0079 deprecation of
titleFormat. - ⛔ This is not a regression from objectui#10358. That PR's declared-pointer branch runs first and does not touch this scan.
- ⛔
record-details.tsxis currently touched by open PRs objectui#10279 and objectui#10358. Serialise behind them.

A1 partly falsified: formatTitleTemplate exports no placeholder parser (its regexes are inline), so literal reuse needed a new @object-ui/core export outside the claimed file surface; the renderer is used as the oracle instead, so no second regex exists and every token shape it accepts (double-brace, inner whitespace, dotted lookup paths) agrees by construction. A2's example premise is falsified (two placeholders holding the same value render a composite, both rows stay, pinned); the real two-equal case needs a dotted lookup ({owner.nickname} - {rep}), where the row whose placeholder rendered the H1 goes and the merely-named lookup stays (pinned); A3 and A4 confirmed, the 8351 file is untouched and green.

The contract-review record is on the PR.titleFormatbranch of the H1 dedupe runs the unchanged candidate scan first, and that scan wins. If no candidate matches, it hides the first record field whose display value EQUALS the rendered title AND that the template actually rendered. "Rendered" is asked offormatTitleTemplateitself: blank that one field, render again, and see whether the output changes{f}and{f.path}). The renderer normalises double braces and inner whitespace itself, so the oracle agrees by construction. The cost: one extra render per key whose value equals the H1, only when step 1 missed{owner.nickname} - {rep}and an empty nickname,reprendered the H1 and is hidden, while the lookup row stays (pinned)page:headerbeside the real body. 2 of 5 red on base.
