spec(data): `field-scale.ts` states that a server `sum` / `avg` over a no-fixed-width `number` does not yet carry its width, and the ruled end-state — ruling A (deferred) on objectui#11254

[objectstack-fleet]

Filed by the director seat, summon #32, session_016tKoy8NJa35Yih1FdzrVmn, as the one executable step of the maintainer's ruling A (deferred) on objectstack-ai/objectui#11254 Q1. The ruling is batch #261 item 4, maintainer 「其他四张同意」; the record is the Ruling: comment on objectui#11254. ⛔ Not a claim.

What was ruled

• The end-state (A). For a sum / avg over a number field with no declared scale, the analytics result reports the width. Its column metadata carries the widest decimal count among the values the server read, or the field's declared scale when there is one. The object-metric tile rounds to that. This is the party that sees the inputs reporting the width (contract-first).
• Deferred. Nothing is built now. The trigger is the first first-party producer: an object-metric tile or dataset measure doing sum / avg over a number that declares no scale and whose author wrote no format. Then A is built in one go, with no new decision card.
• Until then. The tile keeps its whole-number pattern for that one case (objectui packages/plugin-dashboard/src/ObjectMetricWidget.tsx:354 on main 8001068b9c). The protocol must not claim more than the runtime delivers: that is this card.

The defect this card fixes in the protocol text

packages/spec/src/data/field-scale.ts:59-71 (spec main d34aa58a2a) states ruling A′ as protocol: "a computed result over a no-fixed-width column rounds to the widest decimal count among the values that entered it — derived from the data, ⛔ never a constant".

• That holds for computed results whose inputs the renderer sees: the grid summary footer, and the tile's min / max, where the result is an input (objectui PR Land the verified REST-operations mapping table as a references fact sheet — every fleet operation's channel (REST endpoint / GraphQL-only / git zero-quota), session-verified 2026-08-23 #11375).
• It does not hold today for a server-side sum / avg. The tile never sees the inputs, and AnalyticsResultResponseSchema's column metadata (packages/spec/src/api/analytics.zod.ts:94-125) carries format / currency / percentScale and no width.
• An author or agent reading the docblock today is told a guarantee the runtime does not give.

Scope

1. In field-scale.ts, the A′ paragraph states the server-aggregate exception, at the same place and in the same voice:
   • which computed results the rule binds today;
   • that a server sum / avg over a no-fixed-width number still shows a whole number;
   • the ruled end-state (the analytics result reports the width) and the trigger above;
   • the two declared channels an author has today: a field scale, or a tile format.
2. ⛔ No schema change, no new key, no runtime change. Clause-②: no. A patch changeset, since the docblock ships in the published types.

Lane

domain:spec, level S, mode:subagent. The same-family display carriers (the gantt tooltip's number row, NumberCellRenderer) stay on objectui#11254, in domain:ui.

Dedupe

mcp__github__search_issues, repo-scoped, open and closed, 「field-scale computed result server aggregate width analytics column metadata scale」 → 8 hits, all closed. The nearest is #20241, a stale grid description in the same docblock, already fixed. None records the server-aggregate gap.

Dedupe words: field-scale server aggregate width · A prime metric tile sum avg · analytics column width

(1) The widest-decimal rule binds today only results whose inputs the renderer sees: the grid summary footer, and the object-metric tile's min / max. (2) A server sum / avg over a number with no declared scale does not get that width, because the tile receives one number and AnalyticsResultResponseSchema's column metadata has no width. Measured at .objectui-sha pin 89cad75d5570, the object-metric tile shows that answer as a whole number, and the dataset-bound tile with no measure format rounds it to at most two decimals. (3) The ruled end-state A (the analytics result reports the width) and its trigger. (4) The two declared channels today: a field scale, or a format. The diff is comment-only: no schema, key, export or runtime change. Two things differ from the dispatch and the card, and both are measured. First, there is NO patch changeset and the PR carries skip-changeset, because the module docblock ships in no published file (see deviations). Second, the card's \"still shows a whole number\" holds on the object-metric tile only. The docblock states what each face does at the pin.",

ACCEPT — PR #21449 @ 97a757c216

domain:spec seat 1 (session_01UtnxvdiN376GF3sgXwAw4d), holder of claim 5957645758 · 2026-10-02T18:34Z

• Shape (read on GitHub): a draft against main. The first line is Fixes #21183, then Clause-②: no. PR assignee os-sales, label skip-changeset. The branch's delta against main is 1 file, +25 / -1: the A′ paragraph of packages/spec/src/data/field-scale.ts's module docblock, all comment lines. No governed path.

• Review: at-tier PASS 5958810461 on this head. Its findings:

  • No accept-set or surface change.
  • Each sentence is true at .objectui-sha pin 89cad75d5570 and on main:
    • the widest-decimal rule binds today only the grid summary footer and the object-metric tile's min / max;
    • a server sum / avg over an undeclared-scale number gets no width, because AnalyticsResultResponseSchema's column metadata carries none and service-analytics copies only the measure format;
    • each tile's behaviour is stated as the pin does it;
    • ruled end-state A and its trigger are in the ruling's own words;
    • a field scale is said to reach only the face it reaches.

• skip-changeset, confirmed by that same-head PASS. The card's premise that "the docblock ships in the published types" is false, on three readings:

  • files[] ships src/**/*.zod.ts only, and field-scale.ts is not one;
  • the build drops sourcesContent;
  • the published @objectstack/spec@17.6.0 tarball carries none of this module docblock's text, while it does carry the exported resolveFieldScale TSDoc.

  The diff publishes nothing from any released package, which is the case AGENTS.md reserves skip-changeset for.

• Card premise, in part (the dev's measured correction): "still shows a whole number" holds on the object-metric tile only. The dataset-bound tile rounds to at most two decimals. The docblock states each face, without departing from ruling 5933283974.

• Gates on this head: 39 check-runs: 32 success, 7 skipped, none failed and none pending. check-expected-skips: OK. check-governed-merges --pr 21449: NOT governed, 26 changed lines. mergeable_state: clean. A local git merge-tree against origin/main 53fd35e3e3 merges without conflict. No main commit since the merge base touches the file, and no open PR touches it.

• Out-of-scope finding: the dataset-bound tile's min / max also round to a constant two decimals with no measure format. That is an A′ gap of ruling 5933283974 Q2's family, with no first-party producer, and it is covered by end-state A once built. Recorded beside Q2 on plugin-dashboard: ObjectMetricWidget formats a number or percent aggregate with an inferred 0,0 / 0,0% pattern and never reads the resolved width, the metric half of ruling A′ (objectstack#19628) left open by objectui#9843 objectui#11254 (5958830649), so it is findable where its family lives; not filed as a card.

Landing: ready, then auto-merge through the merge queue.

• Landed: PR spec(data): field-scale.ts states that a server sum / avg over a no-fixed-width number does not yet carry its width, and the ruled end-state (#21183) #21449 went through the merge queue as b94a2a7277, with one parent (086ad0aa68). Its one file, packages/spec/src/data/field-scale.ts, is blob-equal to the accepted head 97a757c216, on the merge commit and on origin/main.

• Review: at-tier PASS 5958810461, which also confirmed skip-changeset (the module docblock ships in no published file); ACCEPT 5958844826.

• What changes: field-scale.ts's A′ paragraph now states what the protocol delivers today and what it does not, per ruling A (deferred) on plugin-dashboard: ObjectMetricWidget formats a number or percent aggregate with an inferred 0,0 / 0,0% pattern and never reads the resolved width, the metric half of ruling A′ (objectstack#19628) left open by objectui#9843 objectui#11254:

  • The widest-decimal rule binds only the results whose inputs the renderer sees: the grid summary footer, and the object-metric tile's min / max.
  • A server sum / avg over a number with no declared scale gets no width, and each tile's behaviour is stated as it is at the pin.
  • The ruled end-state (the analytics result reports the width) and its trigger.
  • The two declared channels today: a field scale and a format, each only on the face it reaches.

  No schema, key or runtime change.

• Recorded, not filed: the dataset-bound tile's min / max constant two decimals, beside Q2 on plugin-dashboard: ObjectMetricWidget formats a number or percent aggregate with an inferred 0,0 / 0,0% pattern and never reads the resolved width, the metric half of ruling A′ (objectstack#19628) left open by objectui#9843 objectui#11254 (5958830649).
