[finding] currencyConfig.precision is declared and validated against ISO 4217, but no renderer or runtime reads it — an ADR-0049 enforce-or-remove case, filed on ruling 乙 on #19910

Filing gate: ① a defect, class (c): an author, AI or human, sets currencyConfig.precision expecting it to decide a currency's decimal places, and nothing honours it. Filed by domain:spec execution seat 1 (session_013RDBh5DqXd2xnLwvHLgLFr) because the maintainer's ruling orders it. ⛔ Not graded or routed here; that is triage's.

Provenance. Ruling 乙 on #19910 (record 5805782503, batch #218 item 2, maintainer 「其他同意」), item 3, verbatim: 「Two findings follow through the filing gate, filed by the domain:spec seat, ⛔ not riders: currencyConfig.precision is declared and read by nothing (ADR-0049 enforce-or-remove); objectui's CurrencyField reads the field-level precision (a digit count) as decimal places.」 This is the first of the two. The second goes to objectstack-ai/objectui.

Readings, re-taken at filing on `origin/main` `c8399867b8`

Declared: packages/spec/src/data/field.zod.ts:1663 declares currencyConfig: CurrencyConfigSchema.optional(), and CurrencyConfigSchema carries precision.
Its only reader is its own validation: field.zod.ts:457-458 checks an authored precision against the currency's ISO 4217 digits, via currencyPrecisionContradiction.
Nothing reads it for behaviour. A git grep -n -E "currencyConfig" over packages/*/src, non-test, finds these, and none of them reads precision:
- driver-sql/src/builtin-column-collision.ts:89 (storage mode);
- service-analytics/src/analytics-service.ts:1794 and plugin.ts:1070-1084 (defaultCurrency only);
- spec prose.
Firing control: the same instrument finds currencyConfig?.defaultCurrency read at service-analytics/src/plugin.ts:1084.
Renderer side, at .objectui-sha 62597c588072: packages/fields/src/widgets/CurrencyField.tsx resolves decimals from the field-level precision or the ISO 4217 minor unit. The file's own comment says the currencyConfig key is one 「this widget never reads」 ([Decision] Ruling 5791803339 points currency authors at currencyConfig.precision — but nothing reads that key, and removing scale leaves two console faces rendering currency with zero decimals until objectui#10221 lands #19910 triage 5800441682).

⇒ A declared, validated key whose value changes nothing a user sees.

The decision this card carries (ADR-0049)

Enforce it (a named consumer reads currencyConfig.precision), or remove it (a retirement with its ADR-0087 entry). Ruling 乙 on #19910 already set the direction for currency: 「a currency's decimal places are the currency's, not a setting」. That reads toward removal, but ⛔ this card does not decide it.

Related, ⛔ not folded

PR fix(spec,objectql)!: retire scale from the currency field type — refused at parse, no longer enforced on writes #19909 (card [finding] FieldSchema.scale on a currency field is offered to authors by the field designer, ignored by every display face, and still enforced on writes — half-live in the direction that surprises #19629) retires scale on currency; under ruling 乙 its remedy no longer points at this key.
currency fields: hide the scale designer control; the summary footer and the metric tile take a currency's decimals from its ISO 4217 minor unit (objectstack#19910 ruling 乙) objectui#10221 widens the summary footer and metric tile to the ISO minor unit.

Evidence from the domain:spec execution seat 1 (session_013RDBh5DqXd2xnLwvHLgLFr), 2026-09-24T18:31Z. These are two neighbours measured by the round-3 dev of PR #19909 on its head d7740c324e. ⛔ This is not a claim, ⛔ no label is changed, and ⛔ no new card is filed. The card's disposition carries them.

Aliases into the unread key. packages/spec/src/data/field.zod.ts:420: CurrencyConfigSchema renames scale → precision and decimals → precision. An author who writes currencyConfig.scale has it moved into currencyConfig.precision, the key this card records as read by nothing. Whatever enforce-or-remove disposition this card takes has to take the aliases with it.
Help text that contradicts the field key's describe.
- The field-level precision row in packages/spec/src/data/field.form.ts:78 is offered on currency and number with helpText: 'Decimal places (e.g., 2 for $10.50)'.
- FieldSchema.precision's describe reads "Total digits (non-negative integer)" (field.zod.ts:1211), and objectForm's own precision row says "Total digits" (object.form.ts:189).
- This is the spec-side face of [finding] CurrencyField renders the field-level precision (a total-digit count in the spec) as the number of decimal places — filed on objectstack ruling 乙 (objectstack-ai/objectstack#19910) objectui#10276, where CurrencyField reads the field-level precision as fraction digits. field.zod.ts also records ruling Contract question: should publish-time validation reject a declared currency precision that contradicts the currency's ISO 4217 digits? #7918 (Option A): the field-level precision doubles as the currency display width.
- Which reading is the contract needs settling with that ruling. It is listed here so that the card which settles the currency width sees all three faces.

Unlock scan: the same-file holder merged · `pm:blocked` → `pm:queue`

Triage seat (objectstack-wide, seat post #6015) · session_01W89enF2dYV7K4N2Fbfj33f · 2026-09-27T06:01Z. ⛔ Not a claim, ⛔ not a dispatch. This is part of the blocked-card cleanup the maintainer asked for in this session's chat (「继续清理」, 2026-09-27).

The blocker cleared. Blocked-by: #19909 was PR fix(spec,objectql)!: retire scale from the currency field type — refused at parse, no longer enforced on writes #19909 ([finding] FieldSchema.scale on a currency field is offered to authors by the field designer, ignored by every display face, and still enforced on writes — half-live in the direction that surprises #19629, retiring the currency scale), which held packages/spec/src/data/field.zod.ts. It merged at 2026-09-25T01:00Z. That PR was the file holder, not this card's own work, so this card is free to take.
The premise still holds on origin/main:
- CurrencyConfigSchema.precision is still declared (field.zod.ts:435), with the aliases decimals / scale → precision (:420);
- its only reader is still its own ISO 4217 check (:458);
- field.form.ts:78 still offers the field-level precision with the help text 「Decimal places」, against the describe 「Total digits」 (the neighbour evidence 5819897278).
Direction unchanged: remove, per ADR-0049 with the ADR-0087 retirement entry, under ruling 乙's principle that a currency's decimal places are the currency's. The aliases go with the key. If the claim measures a real reader, stop and report it here.
Serial constraints. finding(spec): the #7918 anchor reads a currency field's precision as its display width, refusing precision: 18 on a fixed-USD field though the key is "Total digits" and ruling 乙 gives decimals to the currency #20011, released in this same act, edits the same currency-precision checks. Take the two serially, or in one PR.

priority:p3 · domain:spec stay.

Family site appended: the FIELD-level `precision` also has no reader · 2026-09-27T09:22Z

domain:spec seat 1 (session_01Rjy9MeetSfq34PKn81CRiN), from the #20011 dev report (PR #20209, out_of_scope_findings[0]). ⛔ Not a claim. It is recorded here because this card owns the family 「a declared precision key that nothing reads」, and the closure rule appends sites to the family card rather than filing them singly.

Site: packages/spec/src/data/field.zod.ts FieldSchema.precision, .describe('Total digits (non-negative integer)') (:1219 at PR fix(spec): a currency field's precision is total digits — stop refusing precision: 18 on a fixed-USD field (#20011) #20209's head), on every numeric field type.
Reach, a named producer: objectui at pin f8a9d0fb packages/app-shell/src/views/metadata-admin/inspectors/ObjectFieldInspector.tsx:917-919 writes a top-level precision (patchDef({ precision: v })) on every numeric type.
No reader, measured by the dev:
- storage gives every numeric type a fixed (65, 30) column (numeric-column-representation.ts:227 for currency), and driver-sql builtin-column-collision.ts:77 says 「this driver does not read it yet」;
- no objectql total-digit check (number with precision: 1, scale: 2 parses and is refused nowhere);
- no objectui face reads it at the pin (83 non-test hits: comments, types, pass-through copies, the designer write).
Stale ledger evidence: packages/spec/liveness/field.json props.precision still says live, citing objectui @11c1e71e reads (CurrencyField.tsx:45, PercentField.tsx:13, index.tsx:662, useColumnSummary.ts:261) that are all retired at the pin.
Consequence: an author (or an AI) writing precision: 10 and expecting a DECIMAL(10, s) bound is silently ignored.
Context: PR fix(spec): a currency field's precision is total digits — stop refusing precision: 18 on a fixed-USD field (#20011) #20209 (finding(spec): the #7918 anchor reads a currency field's precision as its display width, refusing precision: 18 on a fixed-USD field though the key is "Total digits" and ruling 乙 gives decimals to the currency #20011) removed the field-level ISO 4217 comparison, because the key means total digits, not decimals. It kept the currencyConfig.precision anchor, which is this card's original site.

No open PR touches record-validator.ts, field.zod.ts or liveness/field.json (open-PR file lists read at this claim).
record validator's number arm accepts any value whose Number() is finite, so POST /api/v1/data with a number field [500] answers 201 and driver-sql stores the text '[500]' #20309 (domain:engine, pm:blocked) will edit the number arm of record-validator.ts for its string half after driver-sql on PostgreSQL answers 500 for a non-numeric string against a number field — where { amount: { $gt: "abc" } } is DATABASE_ERROR / 500 over REST, while InMemoryDriver and SQLite answer 200 with no rows #20336 lands. It is not in flight now; the later lander resolves.

"summary": "FieldSchema.precision ('Total digits') is now enforced at the objectql write seam. record-validator.ts refuses a number/currency/percent/rating/slider write whose digit count exceeds the declared count, with 400 VALIDATION_FAILED and field code max_precision, and never rounds. The count is the SQL DECIMAL(p, s) reading: digits are counted at the decimal places the max_scale rule applies (scaleAllowance), or at the value's own when it applies none (undeclared scale, and currency, where scale is refused); a fraction-stored percent is counted two places right (scale+2, or 2 with no scale). Spec end: FieldErrorCode gains max_precision (the ADR-0114 D2 closed catalog, not ERROR_CODE_LEDGER/StandardErrorCode), with four-locale templates max_precision/max_precision_scaled; the precision describe states the rule; the liveness row is re-evidenced at the write seam.

domain:spec seat 1 (session_01B3TqpoQbTAfG7G74GMDWNW), reviewer of record under claim 5865023687. Dev report on this card (os-dev-report). Readings below are the seat's, taken on GitHub or on origin/main.

check	reading
Shape	Draft, base `main`, first body line `Fixes #19992`, which is the only closing keyword. `mergeable_state` `blocked` (draft), not `dirty`.
Scope	16 files, +638 / −16. The core is inside the claim: `record-validator.ts` plus its new pin file, the `FieldSchema.precision` describe, and the `liveness/field.json` row. The extras each follow from the order or a gate: the REST import pin (the order asked for an envelope pin); the `FieldErrorCode` member in `errors.zod.ts` and its four-locale templates in `validation-message.ts` (A3's registration); the `dispatcher-error-vocabulary.ts` row (`check:dispatcher-error-vocabulary` requires it); `error-catalog.mdx`, and the `types.mdx` currency line, which taught `precision` as decimal places and is now false; and the generated references.
Changeset	`@objectstack/objectql` `minor` + `@objectstack/spec` `minor`, with a BREAKING banner and `Clause-②: yes`. There is no runtime changeset, which is correct: `packages/runtime/src/dispatcher-error-vocabulary.ts` is not reachable from runtime's tsup entry (`src/index.ts`; `http-dispatcher.ts` names it only in a comment), so it does not ship.
Governed / size	`check-governed-merges.mjs --pr 20423`: not governed; 654 changed lines.
Code	`A3`: the new code joins `FieldErrorCode` (ADR-0114 D2's field-level catalog), not `ERROR_CODE_LEDGER` / `StandardErrorCode`; the top-level code stays `VALIDATION_FAILED`.
Evidence	The report's ablation, taken at `bb33240d` with the fix committed first, turned the pin file 18 red / 4 green, and the 4 green are the controls.
CI	Running at the time of this record; judged at the landing window, not here.

Flags carried to the at-tier review (③):

The fraction-stored percent is counted at a two-place floor even with no scale. This is the dev's own reading, pinned and stated in the describe.
open_questions[0] (currency counted at its own decimals). The dev recommends A (no currency resolution at the validator). The seat agrees: one rule an author can predict. It is the reviewer's to confirm or escalate.
types.mdx is a published-doc correction that rides this PR because enforcement made the old line false.

Out of scope, all Acceptance notes (no reach:, nothing filed): the two blog posts that teach precision as decimal places (their shapes are already refused at parse); precision accepted on non-numeric types and inert there; precision: 0 refusing every non-zero write; and the stale QA checklist prose on records-forms.field-type-constraints.

Next: needs:contract-review goes on PR #20423 in this act. The isolated at-tier review runs when a slot frees; on PASS and a green head, the seat lands it through the queue.

Close-out by the domain:spec seat 1 (session_01B3TqpoQbTAfG7G74GMDWNW) at 2026-09-28T15:11Z.

Delivered. PR #20423 merged as b98fbc21a through the merge queue, and this card closed completed on its Fixes line. A field's declared precision (total digits, the p of DECIMAL(p, s)) is now enforced at the objectql write seam: an oversize write is refused 400 VALIDATION_FAILED with the field code max_precision. There is no storage or DDL change. At-tier record 5868385995 PASS at bb33240d. pm:dispatched removed. On main after the merge, the validator arm and max_precision are present, and the regenerated field reference carries the total-digit describe.

What remains, and who carries it.

The major-18 D3 entry text is [finding] Two major-18 D3 entries print CurrencyConfigSchema.precision … unchanged through os migrate meta, which PR #20251 makes false in the same major #20379 (pm:queue), its own card, untouched here.
The PR's acceptance notes stay notes, not cards:
- currency's applied scale when the currency is not resolved at the validator;
- precision: 0;
- two blog posts that teach precision as decimal places;
- the platform-checklist line that says precision is not enforced, which belongs to the next checklist-author sweep.
