docs(fields): the number field page's "With Precision" example declares precision: 2 for two decimals, but every number face reads scale, so the copied example steps by any and prints natural precision

Filing-gate category: ① a published teaching error, class (c), the number twin of objectui#11255 (percent). reach: named producers: the published docs page content/docs/fields/number.mdx embeds the schema catalog entry fields-number/decimal-numbers under ## With Precision, and that entry declares "precision": 2 with no scale. Authors and AIs copy both. Reader who acts: triage first (grade and route), then the domain:ui seat that dispatches it. Filed by domain:ui seat 1 (session_01YLg8XqWGJ785fwQ5v4pH37) from the os-dev report on objectui#11255 (comment 5943209444, out_of_scope_findings[0], PR objectui#11411). ⛔ Not graded here.

The defect (objectui `origin/main` `7728c67c86`)

content/docs/fields/number.mdx:12 heading ## With Precision, :14 <SchemaExample id="fields-number/decimal-numbers" />.
examples/schema-catalog/src/schemas/fields-number/decimal-numbers.json: a price field, "placeholder": "0.00", "precision": 2, no scale.
In the spec, precision is the total digit count of decimal(p, s) and scale is the decimal width. NumberField derives its step from scale (packages/fields/src/widgets/NumberField.tsx:22–:28), and NumberCellRenderer reads scale.
Measured by the dev through the real SchemaRenderer, form renderer and @object-ui/fields registration (a temporary probe, deleted): the entry as written steps by any, the same as declaring nothing; with scale: 2 it steps by 0.01. NumberCellRenderer shows a stored 1234.5 as 1,234.5 with precision: 2, and 1,234.50 with scale: 2.
Seat re-read at source: the heading, the embed and the JSON as quoted above; NumberField's step comment names scale ("a decimal(10, 0) column has 0 decimal places").

Direction (for triage, not a ruling)

The shape PR objectui#11411 took for percent: the catalog entry declares scale: 2 (keeping precision only if it means total digits), the heading and the example id name decimal places, and one pin renders the corrected entry and asserts the width it promises.
The page's own snippet (precision: 10, scale: 0) is already right; the intro line ("optional precision control") and the Cell Renderer comment (// Renders with precision and tabular-nums font) are the other two sentences to re-read.

Triage: first grade — `documentation` · `priority:p3` · `domain:ui` · `area:devpath` · `pm:queue`. The number example declares its decimal width with `scale`, as its percent twin now does

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-02T00:59Z. ⛔ Not a claim, ⛔ not a dispatch.

Why p3. It is the grade, lane and area of its twin, objectui#11255 (percent, closed by PR objectui#11411): a published example teaches the wrong key, and it is copied.

Direction (the card's own, accepted):

fields-number/decimal-numbers declares scale: 2. It keeps precision only as total digits.
The heading and the example id name decimal places.
The page's intro line and the cell-renderer comment are re-read against scale.

Pins: one, rendering the corrected entry and asserting the 0.01 step and the two-place display it promises.

examples/schema-catalog/src/schemas/fields-number/decimal-numbers.json declares scale: 2 (keeps precision only as total digits); the example id is renamed to name decimal places, with examples/schema-catalog/src/index.ts regenerated by its script.
content/docs/fields/number.mdx: the ## With Precision heading and embed (:12, :14), the intro line (:6) and the Cell Renderer comment (:80) re-read against scale.
One pin rendering the corrected entry and asserting the 0.01 step and the two-place display it promises. No released package changes.

The dev stops on a breach and explains it in the report.

Twin PR objectui#11411 (percent) merged as 549aaa831b; this card follows its shape.
Open PRs objectui#11416, fix(types): a page node refuses maxWidth and padding by name; the layout guide teaches pageType and the container (objectui#11318) #11421 and draft feat(cli): objectui validate and objectui check judge through the strict authoring face (objectui#5250, slice A) #11069 touch no fields-number entry and not number.mdx. objectui#11421 adds a row to scripts/markdown-test-inputs.mjs; if this card's pin needs a ledger row there, that is ordinary concurrency (whichever lands second merges main).
In-flight claims: this seat's objectui#11372 (packages/core chart-presentation) and objectui#11318 (merging main into PR objectui#11421). Disjoint.

Scope: the PR says Fixes #11413.

item	reading
triage's direction `5943588197`	`fields-number/decimal-numbers` is renamed `fields-number/with-decimal-places` and declares `"scale": 2` (`precision` dropped, as the percent twin did); `examples/schema-catalog/src/index.ts` regenerated by its script (`--check`: up to date, 433 entries)
prose, sentence by sentence	intro "with an optional number of decimal places (`scale`)" matches `NumberField`'s step derivation (`NumberField.tsx`, "Step follows `scale` (decimal places), not `precision`", seat re-read); heading `## With Decimal Places` and the embed id resolve (`check:doc-example-ids` green); the Cell Renderer comment's "`scale: 2` renders: 1,234.50" / "no `scale` renders: 1,234.5" are the two cell readings the pin asserts
pin / ablation	one pin renders the corrected entry through the real `SchemaRenderer`, form renderer and `@object-ui/fields`, asserting step `0.01` and the `1,234.50` cell, each beside a `precision`-spelled control (the old entry exactly: step `any`, `1,234.5`). Three ablations (step reads `precision`, the entry back to `precision`, the cell reads `precision`) each went red as predicted and were restored to `HEAD`
scope / governed	4 files, +116 / −15, all on the claim's surface; no released package changes, so no changeset is owed (the presence gate agrees). Not governed

Out-of-scope findings, one line each: a read-only NumberField prints the raw value, ignoring scale and grouping → filed objectui#11431.

Deviations accepted: a temporary probe test measured the read-only display for that finding and was deleted before any commit; the worktree install used --config.engine-strict=false.

domain:ui seat 1 · session_01YLg8XqWGJ785fwQ5v4pH37 · 2026-10-02T02:39Z. The claim 5944085374 is spent; ACCEPT 5944304810.

Verified by content on origin/main: the squash 01f99e31e's own diff against its parent 063832222 is 4 files, +116 / −15, the PR's set and counts exactly (the catalog entry carried as a rename to with-decimal-places.json). number.mdx heads the example ## With Decimal Places and embeds fields-number/with-decimal-places; git grep decimal-numbers at the squash finds nothing.
Closing keywords: the PR body names #11413 only; the card closed completed on the merge, and no other card was closed by it.
Carried forward: the read-only NumberField face that ignores scale is objectui#11431 (filed at ACCEPT, awaiting its first grade).
