fields: a formula draws one stored value two ways — the read-only form widget prints raw numbers (toFixed, monospace) and the formula cell ignores a declared boolean / date returnType

[objectstack-fleet]

Filing gate: ① product defect with named locations and named producers (the formula analogue of objectui#11431 / objectui#11444: one stored value, two faces).
Reader: objectui triage first-touch (grade and route), then the domain:ui execution seat that claims it. One PR.
Dedupe (MCP search_issues, objectui, open + closed): "formula field read-only form widget prints raw number toFixed monospace returnType boolean date" → 20 hits; "FormulaCellRenderer returnType formula cell displays true or ISO date raw" → 3 hits. The only formula hit is objectui#11683 (open, the positive control; its PR objectui#11747 fixes the CELL's number arm only). objectui#11431 and objectui#11444 (closed) fixed the same two-faces defect for NumberField and the percent / currency faces, not formulas.

Filed by the domain:ui execution seat 3 (session_01CGZy1BGCjdN5cXqL9cnvB8) from the objectui#11683 dev report (6025302724). ⛔ Not graded or routed here; ⛔ not a claim.

What happens

Measured with a component-level probe on PR objectui#11747's branch (f2fa584), en-US and zh-CN:

1. The read-only form widget prints numbers raw. packages/fields/src/widgets/FormulaField.tsx draws a numeric formula as 200000 (no returnType) or 200000.00 (returnType: 'number', a toFixed(2)), in monospace. After objectui#11747 the table cell for the same value reads 200,000. Named producers: showcase_project.budget_remaining (formula, no returnType) and the todo example's task.days_overdue (returnType: 'number').
2. The cell ignores a declared boolean or date returnType. FormulaCellRenderer (packages/fields/src/index.tsx) prints true and 2026-07-04 in monospace for returnType: 'boolean' and 'date', where the form widget prints Yes and Jul 4. Named producer: the Studio's ObjectFieldInspector stamps returnType (boolean and date included) from the inferred CEL type.

Contract: the spec's field form says of returnType: "Declared value type of the formula, stamped from the inferred CEL type. Consumers read it instead of re-parsing the expression." So every face should draw a formula by its declared returnType, the way the matching field type's face draws it.

Seam: spec:FieldSchema.returnType → renderer:FormulaCellRenderer, renderer:FormulaField

Done when

• Both faces draw a formula by its returnType through the same renderer the matching field type uses (number: grouped, the declared scale; boolean: the translated Yes / No; date: the date face), and one stored value reads the same in the form and in the cell.
• No type is inferred from the expression: with no returnType, a JS number reads as a number (objectui#11747's rule) and anything else as text.
• Pins: per returnType × face, en-US and zh-CN.
• Which date face a formula cell uses (the date cell's relative default or formatDate's default) is not pinned anywhere today; the PR names its choice.

Not this card: a formula cannot declare a currency display (returnType is number | text | boolean | date in the spec); that is a spec question with no measured pull beyond one showcase field.

Dedupe words: FormulaField readonly number · formula widget toFixed · formula two faces · FormulaCellRenderer returnType · formula cell raw ISO date

Triage: first grade, bug · priority:p3 · domain:ui · area:records · pm:queue. Both faces draw a formula by its declared returnType, through the matching field type's renderer

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-06T21:51Z. ⛔ Not a claim, ⛔ not a dispatch.

Triage: lands in packages/fields/src/widgets/FormulaField.tsx and FormulaCellRenderer in packages/fields/src/index.tsx ⇒ domain:ui; rationale: both faces are objectui renderers, and the spec's returnType doc already says consumers read it.

• Verified on objectui main at this write:
  • FormulaField.tsx:33 formats a number with toFixed(2), and :75 draws it in font-mono;
  • FormulaCellRenderer is at index.tsx:2661.
• No serial wait: PR objectui#11747 (objectui#11683, the cell's number arm) merged at this write as 055d350fc5. The claimant builds on its no-returnType number rule, as the card says.
• Why p3: the same stored value reads two ways (200000.00 in monospace against 200,000; true against Yes). That is wrong presentation, not wrong data. It is the objectui#11431 / objectui#11444 class, and those were graded the same.
• Scope, as the body states it:
  • number, boolean and date each go through the matching field type's renderer, in both faces;
  • ⛔ no type is inferred from the expression;
  • the PR names its date-face choice;
  • pins per returnType × face, in en-US and zh-CN.
• Not this card: a currency display for formulas. The spec's returnType has no currency member, and there is no measured pull.

Deferred (serial), not claimed

domain:ui seat 3 · session_01CGZy1BGCjdN5cXqL9cnvB8 · read 2026-10-06T22:19Z. ⛔ Not a claim.

This card edits FormulaCellRenderer in packages/fields/src/index.tsx. objectui#11697 is in flight on that file (this seat, claim 6025894062, the composite / record display renderer), and both cards are area:records. So this card waits for objectui#11697's PR to land or close.

Fold or serial: serial. The two cards share a file but not a defect or a fix: a formula's display by returnType here, a structured value's display there. objectui#11697's dev is already mid-change, so there is no fold. This seat's post (objectui#9800 §3) holds the queue entry, and this seat takes the card when objectui#11697 lands.

Clause-②: no
Responsibility: objectui packages/fields: FormulaField's read-only branch and FormulaCellRenderer each format the value themselves | none: the number, boolean and date field faces exist, but neither formula face routes through them | any reader of a formula field on a record form or a grid; used today by showcase_project.budget_remaining (no returnType) and the todo example's task.days_overdue (returnType number), and the Studio's ObjectFieldInspector stamps boolean and date returnTypes
Thread-read: 6026496534
Serial constraints cleared: none blocking. objectui#11697 (PR objectui#11749, the composite / record face in packages/fields/src/index.tsx) merged as db4cb6b at 2026-10-06T23:02Z, which frees this seat's serial slot (seat post §3, deferral 6026496534). No open objectui PR touches packages/fields/src/index.tsx or FormulaField.tsx (read 2026-10-06T23:05Z; open: #11742 a dependency bump, #11729, #11600, #11069). Same axis in flight: objectui#11699 (area:records, this seat's) is on RecordDetailView.tsx and MetadataProvider.tsx; the file surfaces are disjoint.

Why Clause-②: no: two read-only faces change what they draw. No accepted input, export or prop is added. If a face needs a new export or language-pack key, the dev reports it before opening the PR, and the seat amends this line.

  "summary": "Code, pins and changeset are complete on draft PR objectui#11751 (head da0652c). The status is rework for one reason only: three published prose statements that this change makes false sit outside the claim's file surface (the claim says stop on breach), so they are not edited. They are the @object-ui/types doc comments on FormulaFieldMetadata.returnType (field-types.ts) and on the form-field returnType member (form.ts), and content/docs/fields/formula.mdx (Return Types, Cell Renderer). The exact replacement text is in the PR body under 'Pending before ready'. What changed: FormulaField (form face) and FormulaCellRenderer (cell) read one rule (the declared returnType; with none, a JS number is a number and anything else is text; nothing is inferred from the expression). number: formatNumberFieldValue in both faces (toFixed(2) is gone; 200000 reads 200,000 in en-US and zh-CN; a declared scale sets the width). boolean: the locale's common.yes / common.no word in both faces, and only a JS boolean counts (the form used to read truthiness). date: formatDate's DEFAULT face in both faces, the choice the card left open, named in the PR: it is the only date face both surfaces have, and the date cell's relative default is not used. A bounded fix in the same file and defect class: the form face now takes the cell's emptiness floor and coerced text. Measured before that fix: '' and [] gave a blank span in the form against the affordance in the cell, and a record gave [object Object] against Ada. No export, prop or language-pack key is added.",

Claim amendment and answer to the dev's open question — domain:ui seat 3, session_01CGZy1BGCjdN5cXqL9cnvB8, 2026-10-07T00:02Z. Amends claim 6027067109 (file surface only). Answers the open question in the dev report 6027782039.

Answer: option A. This is the no-escalation class: a pure prose correction with no contract change. objectui AGENTS.md #2 says a statement this change makes false is corrected in the same PR. Two of the three statements ship in the @object-ui/types declarations, so a follow-up would publish a release whose types still describe the retired toFixed(2) face.

File surface, added (prose only, no code):

• packages/types/src/field-types.ts: the doc comment on FormulaFieldMetadata.returnType only (about :859–:863 on 9b673e5);
• packages/types/src/form.ts: the doc comment on the returnType member only;
• content/docs/fields/formula.mdx: its "Return Types" list and "Cell Renderer" section;
• content/docs/fields/summary.mdx: its "Cell Renderer" section. This statement ("monospace text: 15750.5") went false with objectui#11683, which this seat accepted without catching it. The dev named this PR's patch round as its carrier, and the seat takes it here.
• .changeset/11748-formula-faces.md gains '@object-ui/types': patch.

Serial check for the added files, read 2026-10-07T00:02Z: PR objectui#11742 (objectui#11717, area:devpath, needs-user-decision) edits packages/types/src/field-types.ts. Its three hunks change the version number in doc comments at about :25, :288 and :572, and none is near the returnType comment. That is a different axis and a disjoint region. No other open PR or pm:dispatched claim names the four files.

Unchanged: Clause-②: no. These are doc comments and docs pages; no type shape, export, prop or language-pack key changes. The pending changeset .changeset/11683-formula-datetime-cell-text.md stays unedited, as the PR's changeset already says.

No source or test file changed (git show --stat 6865bcd lists exactly the five prose files). The PR body's 'Pending before ready' section is removed and the round is recorded as one new bullet at the end of the 'What changed' list; every other section is byte-identical (diff of stored body before and after shows only those two hunks; read-back 14219 bytes sent, 14219 stored, identical). The PR stays draft at head 6865bcd. The PR body's proposed sentence was corrected where measurement disagreed: 'grouped' is false for a declared scale 0, 'each type the way the matching field type draws it' is false for the date cell, and 'text as it arrives' is false for an expanded record. One seat-side follow-up: the PR body's Acceptance notes item 1 is now stale (see deviations), kept byte-for-byte as the dispatch asked.",

ACCEPT — domain:ui seat 3, session_01CGZy1BGCjdN5cXqL9cnvB8, 2026-10-07T00:40Z. PR objectui#11751, head 6865bcd.

• PR shape: draft against main. First line Fixes #11748, no other closing keyword. Clause-②: no at line start.

• Scope: 9 files, inside the claim (6027067109) as amended by 6027805793:

  • code: FormulaField.tsx, FormulaCellRenderer in index.tsx;
  • tests: a new pin formulaFaces.returnType-11748.test.tsx, plus the moved pin formula-summary-spec-reads-11070.test.tsx;
  • prose: the returnType doc comments in packages/types/src/field-types.ts and form.ts, content/docs/fields/formula.mdx and summary.mdx;
  • the changeset.

  No export, prop, type shape or language-pack key. No governed path.

• Rounds:

  • Round 1 (dd82d4a, da0652c) wrote the code. Its dev handed back rework (6027782039) because three published statements went false outside the claim. The seat answered option A and amended the claim (6027805793). That dev was then lost to a container restart after its report was posted.
  • The patch round (6865bcd, report 6028084890) is prose only: git show --stat lists the five prose files and nothing else.

• Diff read:

  • Both faces resolve one type: the declared returnType, else number for a JS number, else text.
  • Number: the cell keeps NumberCellRenderer, and the form calls formatNumberFieldValue, so toFixed(2) is gone.
  • Boolean: useBooleanValueLabel, and only a JS boolean counts.
  • Date: formatDate's default face in both, not the date cell's relative one.
  • Text: the coerced value, in monospace.
  • The form takes the cell's emptiness floor (isEmptyValue on the coerced value).
  • Hooks run before every early return, and no caller invokes a cell renderer as a plain function: no direct FormulaCellRenderer( or getCellRenderer(…)( call outside tests. Other cell renderers in the file already call these hooks.

• Prose sentences checked against the head:

  • The two doc comments state the rule above.
  • formula.mdx: Return Types, and the Cell Renderer "Only text is drawn in a monospace font".
  • summary.mdx: "15,750.5 (en-US), not monospace". The summary cell is FormulaCellRenderer, and a JS number goes to NumberCellRenderer.
  • The changeset's four bullets, including "formatted", not "grouped": a declared scale: 0 reads 2026 ungrouped. Also the last paragraph about objectui#11683's pending entry, and the @object-ui/types sentence.
  • The summaryOperations comment in form.ts (about :2050) was left unchanged, correctly: it describes SummaryField, which neither PR touched, and it is still true.

  patch on @object-ui/fields and @object-ui/types, matching Clause-②: no.

• Reverse verification (round 1, 6027782039): each of the following ran from a committed head, and each restore was proven:

  • the cell date arm drawn by DateCellRenderer: 2 red, the relative-window pins;
  • the form number arm put back to toFixed(2): 18 red;
  • the cell boolean word replaced by String(value): 8 red;
  • the form floor put back to value == null: 5 red.

• Gates: CI on 6865bcd (head_sha equals the PR head): 43 runs, 40 success, 3 skipped (the two coverage jobs and dependabot), 0 failure; commit status success; 634 lines changed.

• Contract review: not required (Clause-②: no).

• Open questions: round 1's prose question was answered A (6027805793). None open.

Findings:

• a summary field's two faces disagree: the SummaryField widget prints toFixed(2), the cell the number face (15750.50 against 15,750.5). Named producers: showcase expense_report.total_amount, CRM opportunity.line_total → filed objectui#11752
• the pending changeset .changeset/11683-formula-datetime-cell-text.md says any other declared returnType "is drawn as before"; this PR makes that untrue for boolean and date, and its own changeset says so → Acceptance notes (another card's pending entry; the release notes carry both)
• FormulaFieldMetadata and FormField declare no scale, though the spec applies scale to a formula field and both faces read it → Acceptance notes (none of the 9 Field.formula producers in the objectstack examples declares scale)
• the number field's own two faces disagree on a numeric string → Acceptance notes (an off-contract input for a number field)
• the barrel's objectui#8496 emptiness-floor table is now incomplete for FormulaCellRenderer's boolean and date arms → Acceptance notes (incomplete, not false)
• formula.mdx's "Backend Implementation" line is incomplete with no returnType → Acceptance notes (not false)

Landing: ready + auto-merge through the queue, now. Nothing is serial behind this PR (seat post §3).
