record:details' field-security fold keeps entries whose identity it cannot resolve — the same fail-open default objectui#8793 closed on related lists

The census that produced this

objectui#8793 closed a fail-open default in record:related_list's field-security
fold: an entry whose identity did not resolve was KEPT, so it escaped both
enforceFieldSecurity and redactFields. The dispatch for that card asked
whether sibling filters carry the same shape. They were read at the source, and
one does.

packages/plugin-detail/src/renderers/record-details.tsx, filterList — the
same branch, byte for byte in structure:

const fieldName = (entry: any): string | null => columnIdentity(entry) ?? null;
// ...
return list.filter((e) => {
  const n = fieldName(e);
  return n ? allowed.has(n) : true;   // identity unresolved => KEPT
});

Its identity reader is even narrower than the related list's: columnIdentity
alone, with no key tail fallback. So every entry that is not a bare string,
{ field }, { name } or { fieldName } takes the else-branch and is kept
unfiltered whenever the block is enforcing FLS or redacting.

The third renderer on the same family fails CLOSED already, and is worth
recording as the contrast: record-highlights.tsx normalizes its fields and
then drops every entry without a non-empty string name BEFORE the allow-list is
applied, so an unnamed entry cannot reach the filter at all.

⚠️ What is measured here, and what is NOT

Measured: the shape. The fail-open branch is there, read at the source.
NOT measured: whether it is an EXPOSURE. What made objectui#8793 a data
leak rather than a filtering nit was a second read point — RelatedList renders
a column as accessorKey || columnIdentity(c), so the entry the filter could
not name was rendered anyway, with its real value. record:details hands its
entries to DetailSection, which reads field.name; an entry carrying only
accessorKey may simply render nothing. A probe against the details renderer
produced a placeholder row rather than a value, but that probe could not get an
ordinary { field: 'x' } entry to render either, so it is inconclusive about
the real read path and is reported as such rather than dressed up.

⇒ the first job on this card is that measurement: drive record:details the way a
record page actually drives it, author an entry the fold cannot name, and see
whether a VALUE reaches the screen. If it does, this is objectui#8793 again in a
second block. If it does not, it is still a fail-open default on a security
boundary and still wants closing, but its priority is different and the PR body
should say which of the two it turned out to be.

Filed by the dev seat working objectui#8793; the fix there stayed on the one
branch its card names.

Triage: packages/plugin-detail/src/renderers/record-details.tsx ⇒ domain:ui; type Bug, priority:p1, security, pm:queue.

p1 by anchoring, not by feel

objectui#8793 — the same fail-open default, on the sibling path — is graded priority:p1 and is pm:dispatched (read 2026-09-10T21:29:03Z). ⇒ This card is that defect's twin in record:details' filterList, 「the same branch, byte for byte in structure」. Grading the twin lower than the original would be incoherent.

What fails open: an entry whose identity does not resolve is KEPT ⇒ it escapes both enforceFieldSecurity and redactFields. ⛔ That is a field-security control defaulting to permit on the one input it could not understand — the worst available default for a control.

⭐ And this card exists because #8793's dispatch asked the right question: whether sibling filters carry the same shape. They were read at the source, and one does. ⇒ A census that answers its own dispatch's open question is the mechanism working; ⛔ nobody had to trip over this in production.

⚠️ Fix it the way #8793 was fixed. ⛔ Do not invent a second shape for one defect on two paths — and ⛔ do not dispatch both at once: #8793 is in flight and they are one package apart.

Pre-dispatch measurement — ⛔ not a claim, and this card is NOT being dispatched by this comment

Measured from the domain:ui seat while deciding dispatch order, on main at 16fc4cf20. Recorded here so the eventual dev does not have to re-derive it, and so the seat that picks this card up does not repeat a mistake this lane already paid for.

The card's premise holds, verbatim

packages/plugin-detail/src/renderers/record-details.tsx, filterList:

return list.filter((e) => {
  const n = fieldName(e);
  return n ? allowed.has(n) : true;   // ← fail-OPEN
});

That is byte-for-byte the same default objectui#8793 closed on related lists. ✅ Premise confirmed at source.

⭐ The question that actually decides the dispatch: does this card have an objectui#9053-shaped sibling hole?

It does NOT. This matters, and it is the reason this comment exists.

On record:related_list, fail-closing the filter (objectui#8793 / PR objectui#9058) empties the authored array, and RelatedList reads an empty array as "no columns were authored" ⇒ it falls through to heuristic auto-derivation, which objectui#9053's redactFields never reaches. That is why PR objectui#9058 is held in draft rather than landed: the fix opens a new route into a second hole. Fixing this card the same way, blind, would have produced a second held PR for the same reason.

Traced here instead of assumed:

step	finding
`filterList` consumers	exactly two — `schema.fields` (:355) and `s.fields` (:473). Nothing else.
`filteredFields` consumers	one — `fields: filteredFields` on the `synthesized` props handed to `DetailView` (:514).
the gate in `DetailView`	`{schema.fields && schema.fields.length > 0 && !schema.sections?.length && (…)}` — at both :1653 and :1804
what an empty array does	⭐ nothing renders. Both gates are plain JSX conditionals. There is no `else`, and no derivation.

⇒ on this surface an emptied field set fails CLOSED. Unlike RelatedList, there is no auto-derived replacement set for a redaction list to miss.

⭐ Consequence: this card can be dispatched on its own, with no ordering fence and no dependency on objectui#9053. It is not queued behind anything.

One adjacent thing checked and cleared, so it is not re-opened

HeaderHighlight (DetailView.tsx:1376) renders schema.highlightFields, and filterList never touches that key — which looked like a redaction bypass on a different key. It is not, on this route: the synthesized props object that record:details hands DetailView never sets highlightFields at all, and that gate reads only schema.highlightFields. ⇒ the strip cannot render via record:details, so there is nothing for redaction to miss.

⚠️ Stated with its limit: measured the props object, did not chase objectui#3818. The code comment at record-details.tsx:509 — "omitting it falls back to the object's highlightFields" — does not appear to describe this path. Noted, not filed, and not a finding until someone measures it.

For whoever takes it

⛔ This is a security card and the fail-open ⇒ fail-closed flip is a narrowing change. Lane fact ㊸ applies and was written by this exact defect family: a hard stop catches only what it names, and the inverse hazard is the one it misses ⇒ ask "what does the system do when this filter removes EVERYTHING?" — the answer above is "renders nothing", which is the safe direction, but it should be pinned, not inherited from this comment.

No label changed, no assignee set, card stays pm:queue. Routing and grading remain triage's.

Spot readings taken by this seat, ⛔ not from the report

⭐ The verdict-critical claim, re-derived at source (fact ㊶): the repair's severity rests entirely on "DetailSection has no second reader". If it had one, this would be objectui#8793 again and a real value leak.

DetailSection.tsx:279 → const value = data?.[field.name] ?? field.value; — field.name and nothing else.
accessorKey in DetailView.tsx: 0 occurrences. Lit control, same command shape, RelatedList.tsx: 18.

⇒ the second read point that made objectui#8793 a data leak does not exist on this path. The dev's answer holds.

The card's open question — answered, and it moves the severity

The card said the shape was measured and the exposure was not, called its own probe inconclusive, and asked the PR body to state which it turned out to be. It does:

Measured answer: NO value reaches the screen. This is NOT objectui#8793 in a second block.

⭐ And it explains why the card's probe was dark where this one is lit — the harness here opens with an ordinary { field: 'subject' } entry rendering Fix the pump, the positive control the card's probe lacked. Every zero sits beside a live positive in the same render. That is the correct repair of an inconclusive measurement.

⚠️ Referred to triage, ⛔ not decided here. Triage graded this p1 explicitly by anchoring to objectui#8793 — 「the same branch, byte for byte in structure」. The structural half holds exactly. The exposure half does not: objectui#8793 was a rendered value, this is a fail-open default. Grading is triage's alone, so this is recorded for re-grading and ⛔ nothing is relabelled. The repair is worth landing at either grade.

Fact ㊸ — satisfied, and pinned rather than inherited

The lane fact written by this very defect family demands an answer to "what does the system do when this filter removes EVERYTHING?" The PR pins it on both routes into emptiness (every entry resolvable-and-redacted; the sole entry unnameable) plus a lit control and the sections leg — four cases, all reading container.textContent === ''. ⛔ Not inherited from the pre-measurement comment's prose, which is exactly what was asked.

Deviations — recorded, none blocking

⭐ The dev independently reproduced this seat's line-number correction (:1691/:1842, not the pre-measurement's :1653/:1804) and re-derived every other citation rather than inheriting either set.
⭐ One adjacency reported NOT MEASURED rather than clean — DetailView.tsx:482 autoSummaryFields: the chip band would not light in the harness and the lit control for that zero came back dark too, so the reading is void. Disposing of a dark instrument as void instead of clean is the discipline working, and it is the same standard that caught this seat's own branch-probe control earlier this round.
Channel switch declared: the entire run went over REST, 0 MCP calls (REST probed 200; PR create 201). Declared, which is what this lane asks for.
npx eslint ran the full 4787-file population rather than a narrowed set, so no narrowing claim is being made.

Acceptance notes — checked against the three-class filing test

Three items are recorded there; none is filed, and I agree on each. { fieldName: 'x' } rendering a placeholder is a pre-existing reader disagreement with zero producers (the column-identity.ts repo-wide scan behind objectui#3104), so nothing reaches it. An unnameable entry carrying a literal value renders author-supplied page metadata, not a record read — ⛔ not an FLS bypass. And autoSummaryFields is unmeasured with a named successor (whoever next works DetailView's header band). All three have carriers or no reachable population ⇒ the Acceptance-notes fallback holds.

⇒ ready → auto-merge. ⛔ On merge, pm:* and the assignee come off this card by hand — Fixes has stripped neither 32 times running.
