finding(app-shell): the Action designer's two panes disagree on the param type vocabulary — the inspector offers datetime / lookup, the preview draws both as plain text boxes

Filed unassigned, as an observation for PM triage — surfaced while converging ActionParam onto its published authority (#6329, PR #6536). Not fixed there: that card's face was the two shadow declarations, and this is a rendering-fidelity question, not a type one.

Verified on the #6329 branch at e660fed22 (identical to origin/main 831be7285 in both files).

What the narrowing exposed

Until #6329, both designer panes typed the param as type?: string, so nothing could compare the vocabulary the inspector offers against the vocabulary the preview renders. With both converged onto the published ActionParam.type (ResolvableParamFieldType — the spec's 49-member FieldType plus objectui's three declared aliases), the two panes are comparable, and they disagree.

ActionDefaultInspector.tsx's PARAM_TYPE_OPTS offers eight spellings. ActionPreview.tsx's renderFieldMock branches on five, and only one of those is options-driven:

inspector offers	what `renderFieldMock` renders
`text`	text input
`textarea`	textarea
`number`	number input
`boolean`	checkbox
`date`	date input
`select`	select only when `options` are present, otherwise a plain text input
`datetime`	plain text input
`lookup`	plain text input

So an author who picks Date/time or Lookup in the inspector is shown a preview of a text box. The preview's stated job is "a faux button / dialog rendered so authors can see the visual weight before they ship it", and for two of the eight offered types it shows something the runtime dialog will not render.

A second, related observation in the same pair

The inspector's per-param editor has controls for field, name, label, type, placeholder, required and defaultFromRow — and no options control, though select is one of the eight types it offers and options is a member of the published ActionParam that ActionPreview already renders. An author picking select there cannot author its choices in that panel at all; the key is reachable only through the collapsed "More fields" SchemaForm. That is also why the select row above degrades: the panel that offers the type cannot produce the data the preview needs to draw it.

Why this is an observation and not a defect report

Nothing here is a parse rejection or a data-loss path — every spelling involved is spec-valid and saves fine. The cost is designer fidelity: two panes of one designer describing the same param differently. Severity is a triage call, not mine; recording it rather than sitting on it.

Not filed as a sub-issue of anything: #6246 (ActionParamDialog carry-over params) is the runtime dialog, not the preview mock, and the open backlog carries no card for renderFieldMock (checked by repository-scoped listing over all 251 open issues plus a local grep — the search endpoint returns 403 for this session, so its empty result is not a reading).

Related: #6329 / PR #6536 (the convergence that made the comparison possible).

Triage (triage seat, hourly round 2026-08-26, session session_017g12KiZdCMYEGXDMLZifEr): graded finding → pm:queue, type Bug, lane domain:ui confirmed. Rationale: the preview's own declared job is to show authors what will render, and for two of the eight types the inspector offers (datetime, lookup) it shows a plain text box the runtime dialog will not draw — the designer contradicts itself on its one subject. The second observation (the per-param editor offers select but has no options control, so the panel that offers the type cannot produce the data the preview needs) is the same seam and belongs in the same card. Scope: extend renderFieldMock's vocabulary toward what the inspector offers, and give the per-param editor an options control (or a deliberate, visible pointer to where options are authored) — ⛔ not a full 49-member FieldType mock gallery; the card's eight offered spellings are the population.

Triage's ruling, verbatim

the preview's own declared job is to show authors what will render, and for two of the eight types the inspector offers (datetime, lookup) it shows a plain text box the runtime dialog will not draw — the designer contradicts itself on its one subject. The second observation (the per-param editor offers select but has no options control, so the panel that offers the type cannot produce the data the preview needs) is the same seam and belongs in the same card. Scope: extend renderFieldMock's vocabulary toward what the inspector offers, and give the per-param editor an options control (or a deliberate, visible pointer to where options are authored) — ⛔ not a full 49-member FieldType mock gallery; the card's eight offered spellings are the population. Serial note: ActionDefaultInspector.tsx / ActionPreview.tsx were just converged by #6329 / PR #6536 (merged) — same-day churn, sync to current main before starting; #6246 (ActionParamDialog carry-over) is the runtime dialog, a different subject.

⛔ The population is eight, not forty-nine

The single most important fence: the eight spellings the inspector offers are the population. A full FieldType mock gallery is explicitly out. If you find yourself adding branches for types no PARAM_TYPE_OPTS entry offers, you have left the card — the defect is that the two panes of one designer disagree, not that the preview is incomplete against the whole type system.

The select-without-options half belongs here because it is the same seam: the panel that offers the type cannot produce the data the preview would need to draw it. Triage allows either a real options control or a deliberate, visible pointer to where options are authored — pick by measurement (does the author have somewhere to put them today?) and say which and why.

⚠️ Sync to current `main` first — this file family churned an hour ago

ActionDefaultInspector.tsx and ActionPreview.tsx were converged by #6329 (PR #6536) and merged as 11f23e9a5. Both now import the published ActionParam from @object-ui/types; the two local shadow declarations are gone. Branch from current main and re-read both files before planning — anything you remember about their shape from the card body predates that merge.

⭐ Relevant consequence you inherit: ActionPreview.renderFieldMock lost its long_text and integer branches in that convergence, because neither is in the member vocabulary and ActionParamSchema is .strict() — a param spelled either way is a server parse rejection and could never reach the preview. So the vocabulary you are extending is already narrower than it was this morning, and narrower for a measured reason. Do not restore those two.

Measure the disagreement before you close it

The card names datetime and lookup as drawn-as-text-box. Re-derive the full comparison yourself on current main: what PARAM_TYPE_OPTS offers versus what renderFieldMock branches on. Report both lists and their difference. The card says eight offered and five branched; if your count differs, yours wins and say so — two of this lane's cards today carried counts that were wrong by one.

What "the preview lies" means here

The preview's declared job is to show what will render. So the bar is not "add branches" — it is the preview and the runtime dialog agree for every spelling the inspector offers. If for some spelling you cannot make them agree without touching the runtime dialog, ⛔ stop: ActionParamDialog is #6246's subject and a different card. Report the fork.

File face

packages/app-shell/src/views/metadata-admin/inspectors/ActionDefaultInspector.tsx, packages/app-shell/src/views/metadata-admin/previews/ActionPreview.tsx, their existing suites, any pin you add, and a changeset.

⛔ Do not edit previews/index.ts or inspectors/index.ts. ⛔ Do not touch ActionParamDialog.

In-flight, do not touch

#6465 (app-shell/core test headers — a different population from your two source files) · #6332 (plugin-grid) · #6534 (app-shell providers) · #6541 (packages/types feedback, packages/components), plus open PRs #6543, #6544, #6546.

Reverse verification required: a pin written first, observed failing against the untouched tree, and the failure should be the disagreement itself — a spelling the inspector offers that the preview draws as something the runtime will not draw — not merely a branch-count assertion.

The card's counts hold, but the membership does not nest: html is branched and NOT offered, so offered-minus-branched = {text, select, datetime, lookup} and branched-minus-offered = {html}. Resolving each spelling through the runtime's own adapter (paramToField -> resolveParamWidgetType -> getLazyFieldWidget, ADR-0059) gives FOUR disagreeing cases across three spellings, one more than the card named: datetime and targeted lookup drew text boxes; select-without-options drew a text box where SelectField draws an empty picker; and text-carrying-options drew a select the runtime never renders (TextField reads no options) - the same defect pointing the other way, previously unnamed. Fix: renderFieldMock now switches on the resolved WIDGET KEY from paramToField rather than the raw spelling, restating no membership table, owning exactly two crossings (authoring `reference` -> resolved `referenceTo`, which resolveActionParams performs; and a field-backed param is never previewed as degraded because it inherits its target). An untyped field-backed param stays options-inferred and is pinned so the type-driven switch cannot take it. Population stayed eight - no FieldType gallery, long_text/integer stay deleted, html rides with textarea because dropping it while narrowing would be a regression, and every other widget key (master_detail included) still falls to the text box: extending the mock vocabulary past PARAM_TYPE_OPTS is deliberately not this card, so that remainder is recorded here rather than filed against a triage ruling that excluded it. ActionParamDialog needed no change - no fork to report. select/options half decided by measurement, not preference: the per-param editor had no options control AND `params` is in CURATED_FIELDS so the collapsed More-fields SchemaForm hides the whole array (the issue body's 'reachable only through More fields' is false - it is not reachable there at all); the only surface left was the raw JSON tab, so a 'pointer' would have read 'leave the designer'.

The narrowing is measured, not assumed: the population comes from eslint's own config resolution, the count from its JSON reporter, and eslint.config.js declares no project / projectService / parserOptions, so type-aware linting is OFF and this diff cannot move the verdict on any file it does not touch. NOT RUN LOCALLY, left to CI: check:eager-closure (needs a console build to emit eager-closure.json); the one new import is packages/app-shell/src/utils/paramToField.js, already imported by ActionParamDialog in the same package, so it adds the module and no new package edge. No ablation in this card - the pin's red/green pair is the reverse verification, and it needed no dist rebuild because vitest resolves these app-shell modules from src.",

The column-identity ratchet (objectui#3104) counts ActionPreview.tsx at one `two-layer` dual read and my rewrite added a second: a `label` derivation inside renderFieldMock that re-open-coded the param-name chain DialogMock had already computed one function up. Removed, not re-triaged: renderFieldMock now receives the fieldLabel its caller derives and renders directly above the control, so the line is gone from the SOURCE rather than hidden from the matcher, and the mock's placeholders now name the param exactly as its visible label does. Inventory untouched, count still 1, no exemption, no skip, no empty commit. NOT converged onto columnIdentity(), and that is the inventory's own ruling rather than my preference: this file's verdict is `two-layer` — 'Action param name, same layering as resolveActionParams' — and the resolveActionParams entry refuses the same borrowing in the same words, because columnIdentity() is canonical-first (a column IS the object field it shows) while a param merely BINDS one, so it would invert the param-name precedence and rename every field-backed param that also names itself. The route taken is the one objectui#3174 took for resolveActionParams: every call site in the file through ONE named reader, so the count is the number of CONCEPTS not the number of open-codings — which is what the gate's 'converge it' message asks for in a file whose verdict is not `column-identity`. Recording one trap: the scanner is a LINE-level heuristic and blind to comments, so my first attempt's TSDoc quoting the chain in prose was itself counted (2 hits again); the rewritten TSDoc says so next to the place the next editor would write it.

Post-merge verification on main (domain:ui seat, session session_011SfZeFWrhGLHmfq61xbz4q). PR #6554 landed as 450f1108e.

This is a separate check from the pre-merge diff review, and what it verifies is that the deliberate omissions survived the queue — the queue drains with other PRs in it, so "the diff was right" and "main is right" are two different readings.

1. The population stayed eight, and the two retired spellings did not come back. PARAM_TYPE_OPTS on main is exactly text · textarea · number · boolean · select · date · datetime · lookup. 'long_text' and 'integer' occur zero times, against a live positive control ('datetime' → 1). This mattered because #6329 deleted both an hour before this card landed — ActionParamSchema is .strict() — and a mock gallery keyed on FieldType would have quietly reintroduced them.

⭐ Worth recording for the next person who greps this file: the textarea entry's label reads 'Long text'. A bare long_text-ish search hits it and looks like a restoration. The claim is the retired value, not the display string.

2. The ratchet inventory is untouched. column-identity.ratchet.test.ts:136 still reads count: 1, verdict: 'two-layer', why: 'Action param name, same layering as resolveActionParams.' The red gate was satisfied by removing the second dual read from the source, not by raising the ceiling or editing the inventory — which is the only acceptable resolution and the one this seat mis-routed at first.

3. The file face on main is exactly the four dispatched files — changeset, the new pin, inspectors/ActionDefaultInspector.tsx, previews/ActionPreview.tsx (647 insertions, 39 deletions). previews/index.ts and inspectors/index.ts are both untouched.

4. ActionParamDialog is untouched — all five of its files, verified at its real path (packages/app-shell/src/views/, not under metadata-admin/). My first check used a guessed path, got "not found", and would have reported a pass from a failed lookup; re-run against the path the tree actually has.

5. The pin is on main and keeps its teeth. ActionDesigner.paramVocabulary.test.tsx, 333 lines. It imports the population by reference — const OFFERED = PARAM_TYPE_OPTS.map((o) => o.value) — and asserts coverage with "PARAM_TYPE_OPTS is the population — a ninth entry needs a case here", so adding a ninth offered spelling without a case fails it rather than passing vacuously.

⭐ On the case count: the file declares 8 it() blocks plus one it.each(CASES…), which expands to the 19 the dev reported. A source-level count of it( is the wrong instrument here and reads as a discrepancy with the report when there is none.

Card closed as completed. Nothing outstanding.
