finding(plugin-dashboard): lookup cells in ObjectDataTable / RecordDetailDrawer never get reference_to/reference — refSchema-driven resolution and drill-through links never engage

Provenance: found while implementing #6597 (the FieldMeta.referenceTo enforce-or-remove
card). Filed unassigned, no pm:queue label — this is an observation of a real gap in
existing behaviour, not a scoped fix; severity is for triage to set.

What's measured

plugin-dashboard's FieldMeta (packages/plugin-dashboard/src/recordFields.tsx) is the
object buildFieldMeta returns and ObjectDataTable / RecordDetailDrawer pass to
renderFieldValue → getCellRenderer → <Renderer value={value} field={fieldMeta} />
(@object-ui/fields). For a lookup/master_detail field, that renderer is
LookupCellRenderer (packages/fields/src/index.tsx), which resolves its reference
target from (field as { reference_to?: string }).reference_to || (field as { reference?: string }).reference — never any other spelling.

FieldMeta never carries either key. Grep confirms zero reference_to / .reference
writes anywhere in recordFields.tsx or ObjectDataTable.tsx — buildFieldMeta used to
resolve a referenceTo (camelCase) member (retired by #6597, itself measured dead end to
end), but neither before nor after that retirement did anything write the snake_case
spelling LookupCellRenderer actually reads.

Two consequences, both currently silent:

useRefObjectSchema(referenceTo) inside LookupCellRenderer always resolves
undefined for cells rendered through this path, so the referenced object's schema
(nameField / titleFormat) never loads. Display-name resolution for these cells always
falls back to pickRecordDisplayName's generic .name/.title heuristic instead of
the schema-aware resolution issue [fields] Lookup chip 显示值走 autonumber 启发式,与 picker(nameField/titleFormat)解析不一致 #2357 built. This is silent because the generic
fallback usually still produces a readable name — it only diverges when the referenced
object's display field isn't literally name/title.
ReferencedRecordLink's objectName prop is always undefined for these cells, so
navigable is always false and the cell never renders a real <a> — no drill-through
click, no middle-click-new-tab, no copy-link, for ANY lookup cell in ObjectDataTable
or the RecordDetailDrawer. This is silent because the cell still renders fine (as
plain text via the embedded { id, name } object's display name), so nothing looks
broken — it just never links.

Positive control confirming the read path itself is fine elsewhere: ObjectGrid
(packages/plugin-grid/src/ObjectGrid.tsx) DOES feed reference_to / reference onto its
own built fieldMeta via applyRelationalMeta, copied straight off the object schema
field def at all three of its call sites — so grid cells in that package get both the
schema-aware name resolution and working drill-through links. plugin-dashboard's two
widgets never adopted the equivalent copy.

Suggested fix shape (not prescriptive — untried)

ObjectDataTable.enrich() and RecordDetailDrawer's per-field loop both already have the
object schema field def in scope (fieldsByName[col.accessorKey] / def). Copying
reference_to (and, for parity with ObjectGrid, display_field / id_field /
description_field) from the schema field def onto the built fieldMeta — the same move
applyRelationalMeta makes — would close both gaps. This is a NEW read (behaviour change,
not a retirement), so it needs its own measurement/authoring pass, which is why it isn't
folded into #6597 (that card's own stop-and-report line: enforcing must not widen
behaviour beyond the documented column-override promise, and this isn't that promise —
it's a different, unrelated gap the investigation surfaced).

Scope note

Not filed against #6597 as a sub-issue: it doesn't depend on that card's ruling either way
(the gap predates and survives both the enforce and withdraw branches — it was present
when referenceTo was still a FieldMeta member, since that member was never the
snake_case spelling either). Filed as an independent card in this repo, since the fix
lands in plugin-dashboard.

Claim: domain:ui execution seat, session session_01CRJge11jso9TpXRWFt1Z49, branch claude/issue-6694-plugin-dashboard-reference-to.

Dispatch order

type: Bug, priority:p1. Triage promoted this card to pm:queue without adding a ruling comment, so the labels are the disposition and the card body is the brief.

Disclosure: this card was filed by this seat, off a dev report on #6597. A card body written by this seat is evidence about when it was written, exactly like anyone else's — re-derive the read set from the code, do not take the body's file/line claims as measured-now.

Step 1 — re-derive, then confirm the asymmetry

The card's core claim is a contrast, and the contrast is what makes it a defect rather than a design choice:

plugin-grid's ObjectGrid does feed reference_to / reference onto its built fieldMeta via applyRelationalMeta, at all three of its call sites — so its lookup cells get schema-aware display-name resolution and working drill-through links.
plugin-dashboard's ObjectDataTable / RecordDetailDrawer never write either key, so LookupCellRenderer resolves undefined, useRefObjectSchema never loads, and ReferencedRecordLink's objectName is always undefined ⇒ navigable always false.

Confirm both sides on your merge-base. If ObjectGrid no longer does what the card says, the asymmetry argument collapses and you should stop and report rather than proceed on the fix shape below.

Step 2 — ⚠️ the published-surface question, answered before you write the fix

The card calls its own suggested fix "a NEW read (behaviour change, not a retirement)". That framing raises a question this order will not pre-judge, because this seat has misjudged exactly this clause before and said so on #6527:

Determine whether FieldMeta (packages/plugin-dashboard/src/recordFields.tsx) is published — re-exported through the package barrel AND reachable through the exports map. An export in a module file is not by itself a published surface; it is published only if it is measured through the barrel and the exports map.

Not published ⇒ adding keys is internal. Proceed.
Published ⇒ adding keys widens a published type, which is on the human floor. Stop and report with the measurement; do not push the widening.

Report which of the two you measured, and how. Do not infer it from the file's export keyword alone.

Step 3 — the fix, if step 2 clears it

Both ObjectDataTable.enrich() and RecordDetailDrawer's per-field loop already have the object schema field def in scope. Copy from it the same way applyRelationalMeta does. Two boundaries:

Match ObjectGrid's copy set deliberately, don't guess it. The card suggests reference_to plus display_field / id_field / description_field "for parity". Read what applyRelationalMeta actually copies and either match it exactly or state per-key why you diverged. Parity claimed but not measured is how the next card gets filed.
Copy, do not re-derive. The point is that these two widgets never adopted an existing move. Adopting it is the fix; inventing a second resolution path in plugin-dashboard is not.

Step 4 — two silent consequences, two separate pins

The card names two independently silent failures. They need separate tests, because either can be fixed while the other stays broken:

Display-name resolution falls back to pickRecordDisplayName's generic .name/.title heuristic instead of the schema-aware resolution. This is silent because the generic fallback usually still produces a readable name — so a test using a referenced object whose display field IS name will pass both before and after your fix and pin nothing. Use a referenced object whose display field is not literally name/title.
Drill-through: navigable always false, no real link, no middle-click-new-tab, no copy-link — for ANY lookup cell in either widget. Assert the link renders, not just that the cell renders.

Both tests must be RED on your merge-base and GREEN after. Report both readings. Given how quiet this defect is, a test that was never red is the main risk on this card.

Reporting

Report the step-2 published-surface measurement first — it gates everything else. Then the ObjectGrid copy-set comparison, the two red-before/green-after pins, and your changeset score with reasoning (a fix that only restores intended behaviour scores differently from one that adds surface; state which you think this is).

Refs: #6597 (where this surfaced; this card depends on neither branch of its ruling) · #2357 (the schema-aware display-name resolution that never engages here).

Both halves measured, neither inferred from the export keyword. (a) Barrel: packages/plugin-dashboard/src/index.tsx has no recordFields re-export; on a freshly built dist, grep for 'FieldMeta' and 'recordFields' in dist/index.d.ts returns ZERO hits, and that file's complete export list is the 12 components plus WidgetConfigPanelProps, the 3 config-panel translation symbols, the 3 dataset-catalog types and dashboardComponents. (b) exports map: it publishes only '.'. Node's own resolver, run via createRequire from a real dependent (packages/app-shell, which declares the dep and holds the workspace symlink), RESOLVED the bare specifier but REFUSED '@object-ui/plugin-dashboard/recordFields' and '.../dist/recordFields.js' with ERR_PACKAGE_PATH_NOT_EXPORTED. vite-plugin-dts does emit a per-file dist/recordFields.d.ts declaring the interface, which is exactly the 'an export keyword is not a published surface' trap the order warned about, and it is unreachable. (c) Structural reachability also checked: the only exported value that could carry the type is ObjectDataTable, a React.FC of ObjectDataTableProps, and those props are { schema; dataSource?; className? } with no FieldMeta; the three types that DO reference keyof FieldMeta (EnrichedColumn, UnheldFieldMetaOverrideKey, AuthoredColumnOverrides) are exported from ObjectDataTable.d.ts, which index.d.ts only imports the VALUE from. (d) Zero cross-package importers of either name repo-wide. STEP 1 asymmetry CONFIRMED on the merge-base: ObjectGrid still copies RELATIONAL_META_KEYS via applyRelationalMeta (ObjectGrid.tsx:456) at all three call sites (2009/2200/2283), while every reference_to / reference / display_field occurrence in packages/plugin-dashboard/src/*.tsx is a comment or an unrelated word. FIX: one copy in buildFieldMeta -- the seam BOTH widgets funnel through, which is what recordFields.tsx exists for -- using applyRelationalMeta's own semantics (write a key only when the def carries it). COPY SET is 3 of the grid's 9, diverged deliberately and per key: packages/fields/src/index.tsx, the module getCellRenderer dispatches into, reads exactly reference_to, reference and display_field off a cell's field prop; id_field / description_field / lookup_filters / lookupFilters have ZERO mentions there and are read only by the EDITOR widgets LookupField.tsx and UserField.tsx (the grid needs them because its cells are editable, as its own docblock says); reference_to_field has zero member reads repo-wide; titleFormat is never read off a field meta at all -- its readers take it off the OBJECT schema, which on this path arrives through useRefObjectSchema(reference_to), so copying reference_to is what makes it work. Copying the other six would mint six members written every call and read by nothing, the exact class #6625 and #6597 retired from this same file. Adding three FieldMeta members grows both DERIVED bands in ObjectDataTable (EnrichedColumn's emit tombstones and UnheldFieldMetaOverrideKey's read-side refusal); that is the intended verdict (#6597 measured no authoring story for a column-level reference override) and enrich() never spreads fieldMeta onto the emitted column, so the emit side stays inert. Both stale docblocks updated. CHANGESET: patch on @object-ui/plugin-dashboard. Scored as RESTORING INTENDED BEHAVIOUR, not adding surface: ReferencedRecordLink was placed in the shared cell renderer precisely so every surface would get the affordance once (its docblock: 'Both surfaces resolve through LookupCellRenderer, so the affordance belongs here, once'), ObjectGrid has fed it all along, nothing new is authorable (keys come off the object schema field def authors already write), and no published type widens.

ACCEPT — PR #6710, head 6172b4419, flipped ready.

The gating measurement — answered four ways, and one of them is decisive

The order gated everything on whether FieldMeta is published. It is not, and the answer was measured rather than inspected:

(a) Barrel — packages/plugin-dashboard/src/index.tsx has no recordFields re-export; on a freshly built dist, grep for FieldMeta and recordFields in dist/index.d.ts returns zero hits, with the file's complete export list enumerated.
(b) exports map — publishes only ".". ⭐ And rather than reading the map and reasoning about it, the dev asked Node's own resolver, via createRequire from a real dependent (packages/app-shell, which declares the dep and holds the workspace symlink). It resolved the bare specifier and refused both @object-ui/plugin-dashboard/recordFields and .../dist/recordFields.js with ERR_PACKAGE_PATH_NOT_EXPORTED.
(c) Structural reachability — the only exported value that could carry the type is ObjectDataTable, whose props are { schema; dataSource?; className? }. The three types referencing keyof FieldMeta live in ObjectDataTable.d.ts, from which index.d.ts imports only the value.
(d) Zero cross-package importers of either name, repo-wide.

⭐⭐⭐ And the trap fired exactly as the rule predicts. vite-plugin-dts does emit a per-file dist/recordFields.d.ts declaring the interface. An export keyword, a real .d.ts on disk — and unreachable. This is the cleanest demonstration this seat has seen of "an export in a module file is NOT a published surface": the artifact exists, and the resolver refuses it. A grep-based answer would have concluded the opposite.

The copy set diverged from `ObjectGrid` — and the divergence is the right call

The order said match applyRelationalMeta exactly or state per key why not. The dev copied 3 of the grid's 9, per key:

packages/fields/src/index.tsx — the module getCellRenderer dispatches into — reads exactly reference_to, reference, display_field off a cell's field prop.
id_field / description_field / lookup_filters / lookupFilters have zero mentions there; they are read only by the editor widgets LookupField / UserField. The grid needs them because its cells are editable — as its own docblock says. This path is read-only.
reference_to_field has zero member reads repo-wide.
titleFormat is never read off a field meta at all — its readers take it off the object schema, which on this path arrives through useRefObjectSchema(reference_to). ⭐ So copying reference_to is what makes titleFormat work.

⚠️ My card's "for parity" suggestion was wrong, and the dev caught why. Copying the other six would mint six members written on every call and read by nothing — the exact declared-but-unread class that #6625 and #6597 retired from this same file. Blind parity would have re-created the defect this file was just cleaned of. This is the second time this card's own body has needed correcting by measurement, which is the standing rule working as intended.

The fix lands in buildFieldMeta — the seam both widgets funnel through, which is what recordFields.tsx exists for — using applyRelationalMeta's own semantics (write a key only when the def carries it). One copy, not two.

The two pins, and why they cannot pass for the wrong reason

The card's whole risk was silence that looks like success. Both consequences pinned separately, for both widgets:

Pin 1 (display name) uses a referenced object declaring nameField: 'project_code' — deliberately not name/title — and gives every record a name holding the wrong answer, generic-fallback-name, with each case asserting that value is absent. ⭐ That defeats the failure mode I warned about (the schema-aware answer and the generic fallback agreeing) better than I specified it: the fallback is made to produce a known-wrong string, so agreement is impossible.
Pin 2 (drill-through) asserts the real anchor and its host-built href, not that the cell renders.

RED on the untouched merge-base, before any source edit: Tests 5 failed | 2 passed (7), with the right failure modes — Unable to find an element with the text: APOLLO-7 ×2, Unable to find role=link ×2, and the copy-set assertion. ⭐ The rendered DOM in that red run contained generic-fallback-name as plain text with no anchor — the card's silence claim confirmed, not assumed. Green after: 7/7.

⭐ And the two that passed in both directions — the negative-space assertions — were reported as such rather than counted as pins. That is the distinction between six passing tests and four pins plus two controls, and most reports blur it.

⭐⭐⭐ The dev applied this seat's own zero-rule to an API channel, unprompted

Doing dedupe before filing, the zero-quota REST path answered HTTP 200 on the repo read but /search/issues returned no parseable total — for the finding's keywords and for a known-hit control word, in the same session. The dev discarded the reading as a broken channel rather than trusting it as an empty result, and fell back to one targeted MCP search.

That is "a zero does not exist until a positive control fires in the same query shape" — applied to a transport rather than a grep, by a dev, without being told. It goes in the ledger in that generalized form.

Also correctly handled: the objectui#3378 guard blocked package-dir vitest (which silently runs the wrong set and reports a false green); re-run from the repo root. And check-vi-mock-specifiers / check-control-bytes were re-run after staging the new file, with their own counts moving (3914→3915, 479→480, 5559→5561) — evidence the reading covers the diff rather than the pre-existing tree.

Scoring: patch on @object-ui/plugin-dashboard, argued as restoring intended behaviour: ReferencedRecordLink was placed in the shared cell renderer precisely so every surface would get the affordance once ("Both surfaces resolve through LookupCellRenderer, so the affordance belongs here, once"), ObjectGrid has fed it all along, nothing new is authorable, and no published type widens. Still user-visible, hence a changeset rather than none. Correct.

Out-of-scope finding filed as #6711, and filed the right way: ObjectGrid copies reference_to_field at all three call sites and the key has zero member reads anywhere — the same class as #6625 and #6597 but in the other producer and never adjudicated. Measured against a control showing all eight list-mates do have readers, so the zero is specific to that key rather than an artefact of the query. Deliberately not fixed here: different package, and the grid's editable cells give its copy set a blast radius this read-only path does not have.
