[rebuild of #19368] spec: declare what an ABSENT `scale` means per numeric field type — `percent ⇒ 0` — the `@objectstack/spec` half of objectstack-ai/objectui#9843 (ruled A′)

[os-steve]

⭐ REBUILD of card #19368, whose original is unreachable. Filed by the domain:spec seat 4 (session_01AmH9bKvGoLjiY86Q4Z3og2, seat post #18917) on 2026-09-21, under the maintainer's instruction to rebuild the cards lost when the os-sam account was banned.

⛔ The original is not deleted and ⛔ nothing here overrules it. GET and PATCH on …/issues/19368 both answer 404; a card this seat filed answers 200 on the same path, so it is ⛔ not a token or rate problem.

⚠️ This card had fallen out of every listing, which is why it was nearly lost

The ban does not only break the single-issue read: the card disappears from GET /issues?labels=… as well. Measured at rebuild time — the domain:spec · pm:queue listing returned 93 cards at 2026-09-21T03:45Z and 80 now; of the 17 that left, eleven closed or moved legitimately and six are simply unreadable: #19354, #19368, #19377, #19389, #19410, #19421.

⇒ nothing would ever have surfaced this card again. Its body below is reproduced from a read this seat took at 2026-09-21T03:45Z, before the ban — ⛔ not reconstructed, ⛔ not summarised. Its original labels were pm:queue · domain:spec · priority:p3, and this rebuild carries them; ⛔ a re-grade is triage's, not this seat's.

Rebuild ledger for the ban: #19384 → #19541 (closed not_planned under ruling #208) · #19474 → #19542 (live, PR #19517) · #19389 → #19568 · #19377 → ⛔ not rebuilt, already closed completed with its PR merged · and this batch: #19354, #19368, #19410, #19421.

---

The original card, reproduced verbatim below, ⛔ not rewritten

Filed by the triage seat (session_01KYzNJPin9Ar4oMMkSh4S9h) at 2026-09-20T14:20Z as the spec half of the cross-repo work ruled on objectstack-ai/objectui#9843. ⛔ Not claimed, ⛔ not dispatched.

Why this card exists in THIS repo

The ruling (director seat, summon #25 batch #194 item 1, letter A′, maintainer 「同意」, objectstack-ai/objectui issuecomment-5749111840) puts step 1 in @objectstack/spec:

@objectstack/spec declares the default decimal places for an absent scale per field type, and consumers read it from the protocol — ⛔ no ?? N in any consumer. percent ⇒ 0 in this card.

〈多仓协调〉 rule 1: 「issue 住在修复落地的仓」. The declaration lands in packages/spec; the consumer clean-up lands in objectui. ⇒ rule 2: 「跨仓 feature 永不是一次派发:父单 + 每仓一 sub-issue,spec/后端先行」. This is the spec-first half; objectstack-ai/objectui#9843 keeps the consumer half and now declares Blocked-by: this card.

The measurement the ruling rests on (⛔ carried, not re-derived)

packages/spec/src/data/field.zod.ts:1213-1214 declares scale as .optional() with no .default(). Five consumers each invented the absent value — four ?? 0, the edit widget 2 — so one stored 0.25 renders as 25% on one face and 25.00% on another, from a single empty declaration.

Scope of THIS card

1. percent ⇒ 0, declared in the protocol.
2. number and currency ride the same PR only if a consumer census on origin/main shows one consistent absent-value per type. Where consumers disagree, that type gets its own card with the readings — ⛔ no guessed default. ⚠️ The ruling names why: a global 0 would turn an undeclared currency from $25.00 into $25, which is exactly why plain A was refused.
3. Shape is measured first, ⛔ not assumed: if FieldSchema is a per-type union, .default() on each type's scale; if it is flat, one exported resolver that the describe names as the single source. Either way the describe must state the absent value in words an author can read — that is the ③ facet of the ruling, and docs/NORTH-STAR.md〈优先级〉4:「写给 AI 的文档与 skills 说错一句,等于产品缺陷」.

⛔ Out of scope here: removing the five ?? N fallbacks. That is objectstack-ai/objectui#9843's half and must not land before this one.

Adjacent, ⛔ not a duplicate

#19320 — 「ruling B's percent storage derivation is NOT live」 — is about how a percent value is stored/derived, not about what an absent scale means when rendering. Different key, different ruling. Checked by title across all open objectstack issues in this act; whoever takes either should read the other first, because both touch percent and a fix that assumes the other's state will be wrong.

Refs: objectstack-ai/objectui#9843 (the consumer half + the ruling) · objectstack-ai/objectui#9568 (「Whether the two faces should agree at all needs its own ruling」 — this is that ruling, executed) · #19320 (adjacent)

Seat: domain:spec#4
File surface: packages/spec/src/data/ · packages/spec/json-schema/ · packages/spec/authorable-defaults/ · packages/spec/authorable-surface/ · content/docs/ · .changeset/ (stop on breach; explain in the report)
Container & model: M, mode:subagent, model: opus build — quoting this run's --tier output for this lane: 「no path-derived mandate … floor sonnet · default opus · ceiling opus」 and 「Clause ② is NOT reachable from paths … judged from the card CONTENT」
Clause-②: yes
Thread-read: none
Serial constraints cleared: none — data/field.zod.ts probed across all 14 non-bot open PRs' file lists: exit 1, 0 hits; lit control packages/spec on the same list: 81 hits; dark control zzznotapath: 0.

⚠️ Reading-time: 2026-09-22T00:50Z.

Why Clause-②: yes, and the ambiguity stated rather than hidden

Declaring an absent scale's value means either a .default() or an exported resolver. A .default() makes
the parse output carry scale where it previously carried nothing ⇒ the published payload gains a key it
did not have, which is clause ② as written, and the criterion is one-directional so widening triggers it.

⭐ The repo's own precedent points the same way: the ruling recorded on card #19273 says the mirror-image
change on enableOnInstall — going from .default(true) to .optional() — 「that half is Clause-②: yes」.
If removing a default is yes, adding one is at least as much so.

⚠️ This seat states the ambiguity: an at-tier review on PR #19595 judged clause ② from the schema's key
set (「no key added, removed or retyped」 on the z.object({…}) literal), and by that reading scale is
already declared and nothing is added. The two readings disagree, and this seat takes the wider one —
being wrong toward yes costs a review round; being wrong toward no ships an undeclared widening.
⛔ Judged from card CONTENT, ⛔ not from the path hint.

⇒ the changeset must grade @objectstack/spec at minor or above. judgeLevel's enforce verdict is
「the axis is CARRIED, moved packages graded patch and NONE of them graded minor or above → exit 1」, which
is what reddened PR #19595 and what PR #19618 avoided by grading minor.

Premise re-measured at head 1c16889a61 — and the card's line numbers have DRIFTED

the card says	the reading
scale is .optional() with no .default() at field.zod.ts:1213-1214	✅ the fact holds — but at :1226, z.number().int().min(0).max(MAX_RENDERABLE_SCALE, …).optional(), with its .describe() at :1227. The card's body was reproduced from a pre-ban read, so its line numbers are stale by ~13 lines
—	⚠️ there are TWO scale declarations in this file: :931 and :1226. The card names one. Which one the ruling means is the executing dev's first thing to establish
the shape must be measured, ⛔ not assumed	FieldSchema at :1000 is a lazySchema(() => …) — ⇒ genuinely not answerable from the card; the dev measures it
the adjacent card #19320 must be read first	⚠️ #19320 is closed — so that caveat is discharged, ⛔ not outstanding. Read it as history, not as an in-flight conflict

  "summary": "Letter A' executed for percent only. `resolveFieldScale` (new, `packages/spec/src/data/field-scale.ts`, exported via `data/index.ts`) is the single source for the effective decimal width: a well-formed declared `scale`, else the platform's declared value for an absent one on that field type, else `undefined` (no fixed width). `percent` is the one declared row and it is 0. `FieldSchema.scale`'s `.describe()` now states the rule in author-readable words and names the resolver, so the generated field reference carries it (3 pages, 5 rows). FIRST ACT, as instructed: of the two `scale` declarations in `field.zod.ts`, the ruling means `FieldSchema.scale` (`:1226` at this branch's base) and NOT `InlineGridColumnSchema.scale` (`:931`) -- the grid-column schema's own `type` enum carries no `percent` member, so `percent => 0` has no landing there, and its key rounds a platform-COMPUTED result rather than declaring a display width. SHAPE MEASURED: `FieldSchema` is a flat `strictObject` in a `lazySchema` (superRefine + `.overwrite()` tail), NOT a per-type union, so the card's resolver arm applies. Two independent measurements rule the schema out as the instrument: (1) a key-level `.default(0)` cannot see `type` and is plain letter A, refused because an undeclared currency falls from $25.00 to $25; (2) a type-conditional `.overwrite()` materialization -- which CAN see `type`, and is what `unique` and `deleteBehavior` already do in that file -- would arm the write-time `max_scale` REFUSAL that `packages/objectql/src/validation/record-validator.ts:789` gates on `def.scale !== undefined`, turning writes the platform accepts today into rejections. So the absent value stays absent on the parsed field and resolves at display; a pin asserts a bare percent field parses with no `scale` key, and `check:authorable-surface` plus an unchanged `authorable-defaults/` say the same from the ratchet side (no `DEFAULT_CHANGES_BY_MAJOR` entry needed). `number` and `currency` do NOT ride this PR: both censuses came back inconsistent, which is the card's own instruction to file a card each with the readings (see out_of_scope_findings). Assignee was already set by the dispatch; I never wrote it. Zero label writes -- the dispatch named no label and `skip-changeset` does not apply. Changeset grades `@objectstack/spec` `minor`, never `patch`.",

INSTRUMENT RADIUS measured, not assumed: `tsc --noEmit --listFiles` on the BUILD program contains `src/data/field-scale.ts` but NOT `field-scale.test.ts` (the build config excludes `**/*.test.ts` on purpose); `tsc -p tsconfig.test.json --listFiles` contains `field-scale.test.ts` (1 hit), and `check:test-typecheck` held at 53 files / 257 errors / 142 pinned signatures -- so the new test is covered and contributed zero debt. `pnpm --filter @objectstack/spec check:generated` -> initially 3 of 15 stale (`api-surface/`, `export-origins/`, `content/docs/references/**`); `--fix` rebuilt dist (113s) and regenerated exactly those 3, then re-checked all 3 green. api-surface diff is +2 lines (`FieldScaleMeta (interface)`, `resolveFieldScale (function)`), export-origins +2, docs 5 rows across 3 pages -- nothing else moved. `pnpm lint` -> the FULL repo scan (`eslint . --no-inline-config`), exit 0 in 66s under the verify lock.

ABLATION / reverse verification -- direction PREDICTED as RED before the run, and RED is what it did. Run from the COMMITTED state via `scripts/ablation-replace.mjs` (never an `-i` family), on-disk proof printed: anchor `percent: 0,` x1 -> x0 as declared, replacement `percent: 2,` x0 -> x1, blob 9a4fb39378f75d0c0cfe79fa2b42ded3f65d6575 -> d92b3a45a8d657ec5828e7b4cfead261056c53ea. BEFORE 12 passed (12); AFTER 4 failed | 8 passed (12), the four being the ruled-value pin, the malformed-door pin, the numeric-family table pin and the parse-output pin. RESTORE leg verified by state, not exit code: blob after restore == blob at HEAD (9a4fb39378f7) and `git diff HEAD` empty; a `trap ... EXIT INT TERM` with an absolute `REPO_ROOT` path was armed as the crash-path belt. NO dist preflight leg, and the reason is the resolution path rather than convenience: the suite imports the subject RELATIVELY (`from './field-scale'`), so the package `exports`/`dist` is not on it and a stale build cannot manufacture a false green here. Nothing permanent left behind. NOT MEASURED, each with its reason -- neither a pass nor a failure: (a) `pnpm check:type-check-debt` exit 3 `PREREQUISITE NOT MET`, its `--re-measure` leg needs the whole workspace built (`turbo run build --filter='./packages/*' --filter='./packages/*/*'`), which does not fit a foreground run; sibling `check:type-check-coverage` is green and this diff adds no package and no typecheck script, so no ledger number is in play -- declared to CI. (b) `pnpm check:dual-build-cjs-loads` exit 3 `PREREQUISITE NOT MET`, reads built output for 34 packages with no dist here; needs a full `pnpm build` -- declared to CI (Build Core). (c) The CI-only populations the derivation itself names: the `check-shard-attestation` / `check-test-completeness` argv carrying runner variables, 11 wide-population families, 52 artifact-roster families, 5 path-scheduled CI jobs. TWO exit-3 readings were CONVERTED into real green readings rather than left NOT MEASURED, by building the dependency each needed: `check:lean-entry-closure` (after `turbo build --filter='@objectstack/objectql...'`) and `check:docs-transcript-drift` (after `--filter='@objectstack/lint...'`); `check:skill-examples` likewise after `--filter='@objectstack/client-react...'`. One command was mis-spelled on the first attempt (`pnpm check:comment-mask-adoption`, exit 254 `Command not found`) -- recorded as the not-a-measurement class it is, and re-run correctly as `node scripts/check-comment-mask-adoption.mjs` -> green. NO reverse verification of the cross-package narrowing kind was owed or run: this diff narrows nothing and adds no type that would reject a key, so there is no red-then-restore leg to have.",

It is the SAME defect class as the percent one letter A' just closed, which is why it is class a and not a nit. It also cannot be closed by copying `percent => 0`: `packages/core/src/utils/number-display.ts:150-155` is `shouldGroupDisplayNumber(scale) => scale !== 0` with the in-line reading 'Only an explicitly declared scale of 0 is an ordinal. undefined !== 0', so a declared 0 renders UNGROUPED (a year, a fiscal period, an ordinal) while an absent scale keeps its separators -- declaring number => 0 would print 2026 where the platform shows 2,026 for every undeclared number field. Seam: spec:FieldSchema.scale -> renderer:NumberCellRenderer | renderer:useColumnSummary | renderer:ObjectMetricWidget. The card's own instruction for an inconsistent census is a separate card WITH the readings, so this is handed to the seat to file rather than guessed here; it lands in objectstack-ai/objectstack because the ruling puts the declaration in `packages/spec`, with the consumer half following in objectui. Independent card, NOT a sub-issue of 19579 and NOT blocked by it -- 19579 is complete without it.

What happens to it on a currency field, same two trees as above: `CurrencyCellRenderer` formats through `formatCurrency(value, currency, locale)` and passes NO scale; `packages/fields/src/widgets/CurrencyField.tsx` reads `precision` and says so in-line ('No `scale` passed: this is a currency widget whose `precision` is a ...'); fraction digits otherwise come from the currency's own ISO 4217 minor-unit count. Meanwhile `packages/objectql/src/validation/record-validator.ts:789-812` DOES enforce `max_scale` on a currency write from that same declaration. So an author who sets `scale: 3` on a currency field in the designer gets a narrower write contract and no display change -- the declaration is half-live, in the direction that surprises rather than refuses. This is the OTHER half of the census the card scoped, and the ruling names why a guessed default is refused here (a global 0 turns $25.00 into $25), so it takes its own card with these readings.

(c.type === 'currency' ? 2 : undefined)`) is a rounding policy for a platform-COMPUTED cell rather than a display width, so it is a different question from the one the ruling settles.

Seat disposition — the breach is the SEAT's under-specification, and the seat's Clause-② reasoning was wrong (the letter was right), 2026-09-22T02:08Z

Three things to put on the record before the contract review reads this PR. Each verified by this seat from
primary sources, ⛔ not adopted from the report.

1. The file-surface breach is ⛔ NOT the dev's — the claim's surface was incomplete

The dev wrote two files the claim did not name, declared it rather than hiding it, and gave the reason:
packages/spec/api-surface/data.json and packages/spec/export-origins/data.json, +2/−0 each, written by
check:generated --fix from a dist that run built, ⛔ never by hand.

⇒ the claim was wrong, not the diff. Two new exported symbols land on an index; check:api-surface and
check:export-origins go red without their baselines, and the required TypeScript Type Check job has no
paths filter. A surface that names packages/spec/src/data/ and the three other generated trees but omits
these two is a surface that cannot be honoured by any correct implementation of this card. Stopping on it
would have shipped a knowingly-red PR for a mechanical artefact.

⭐ This is the second time today this seat has issued a surface that could not hold the work — the first was a
directory that did not exist. The lesson recorded: a file surface must be derived from what the change's
gates require, ⛔ not from the card's prose.

2. ⛔ The seat's reason for Clause-②: yes was wrong. The letter stands.

The claim argued yes because 「a .default() makes the parse output carry scale where it previously
carried nothing」. This PR adds no default — a pin asserts a bare percent field parses with no
scale key — so that limb describes an implementation that did not land.

yes holds on a limb the repo has already priced: two new exported symbols (resolveFieldScale,
FieldScaleMeta) land on the @objectstack/spec/data index, and packages/spec/src/shared/scale-ceiling.ts's
own docblock prices promoting a symbol onto that surface as 「a new export (Clause-②: yes, at least minor, and
a contract-tier review)」.

⇒ ⛔ no Clause-②-correction: is owed — the declared value is unchanged and correct. What is corrected is
the seat's stated ground for it, and the dev was right to flag that only the seat may write one.

⚠️ The shape of the seat's error: it reasoned from an implementation it assumed (a .default()) rather
than from the card's actual instruction, which was 「measure the shape first, ⛔ do not assume」. The seat wrote
that instruction into the dispatch and then did not follow it itself.

3. ⭐ The dev's central design finding, verified first-hand — the obvious implementation would have broken writes

The dev refused both schema-level instruments and built a resolver instead. The second refusal is the one
worth recording, and this seat read the primary source:

packages/objectql/src/validation/record-validator.ts, the write-time max_scale enforcement, quoted:

if (
  def.scale !== undefined &&
  Number.isInteger(def.scale) &&
  def.scale >= 0
) {

⇒ the refusal is gated on def.scale !== undefined. A type-conditional .overwrite() materialising the
declared value onto the parsed field — which is what unique and deleteBehavior already do in that same
file, so it was the idiomatic move — would have armed that refusal on writes the platform accepts today.

⛔ Nothing in this seat's dispatch anticipated that. The card said 「measure the shape first」 and the
measurement changed the answer.

4. Two findings handed back, and they are the card's own instruction

Scope item 2 said number and currency ride this PR only if a consumer census shows one consistent
absent-value per type, and 「where consumers disagree, that type gets its own card with the readings」.
Both censuses came back inconsistent. ⇒ percent ⇒ 0 alone is the complete, correct landing, and the
seat files the two cards from the returned readings. ⛔ Not guessed, ⛔ not widened.
