finding(skills,docs): the currency teaching in `field-types.md` and `field-types.mdx` contradicts the spec: `dynamic` is taught as a per-record `{ value, currency }`, and the resolution order has no mode

[objectstack-fleet]

Filing-gate category: ② a teaching surface that contradicts a declared contract (class b). It is also a trap, because it teaches an AI author a value shape the runtime refuses. Reader: triage first (route and grade), then the seat that claims it. ⚠️ One of the two sites is a governed surface (skills/**), so its fix waits on a human approval.

Filed by the objectui domain:ui execution seat (seat 1, session session_01BA3nKVUwKQJf8DBxrSVtNC) from the os-dev-report of objectui#10422 (PR objectstack-ai/objectui#10461, comment 5826076834). ⛔ Not graded and not routed: domain:*, priority:* and type are the triage seat's.

Fact (read on main at 338feda6d)

The two claims below disagree with the contract.

1. Value shape. skills/objectstack-data/rules/field-types.md, in the "Currency with Precision" example, comments currencyMode as 'dynamic' = per-record { value, currency }. content/docs/data-modeling/field-types.mdx, in the currencyConfig.currencyMode row, says "Whether currency is per-record or fixed". The spec's CurrencyValueSchema is @deprecated because "a currency field's value is a BARE NUMBER everywhere (validator, SQL driver float column, import coercion, field-zoo oracle); the currency code lives in field config". An author who follows either teaching writes an object value into a number column.
2. Resolution order. In field-types.md, the "Currency resolution (ADR-0053)" paragraph says "the field's own currencyConfig.defaultCurrency → the tenant localization.currency default", with no mode condition. The spec's FieldSchema guidance says a fixed currency is declared as currencyConfig: { currencyMode: 'fixed', defaultCurrency: … } and that "A field without one uses the tenant default at runtime". currencyConfig.defaultCurrency also DEFAULTS to 'CNY' (CurrencyConfigSchema), so an unconditioned read makes every dynamic field show CNY. PR fix(i18n): a dynamic-mode currency field shows the tenant currency, not its defaultCurrency (#10422) objectui#10461 (in review) moves the renderer's resolveFieldCurrency to read defaultCurrency only under currencyMode: 'fixed'. Once it lands, the skill's sentence describes behaviour no renderer has.

Grading notes (for triage, not a grade)

• Seam: spec:CurrencyConfigSchema.currencyMode → renderer:resolveFieldCurrency (objectui). Both the skill and the docs page are consumers of it as documentation.
• The shape of the fix is text only, re-derived from the spec: the value is a bare number in both modes. fixed pins defaultCurrency as the field's one currency. Otherwise the tenant default applies. ⛔ No spec change is asked for by this card.
• An observation for whoever takes it, ⛔ not a claim: the spec's own currencyMode describe reads "dynamic (user selectable)". What "selectable" means for a bare-number value is worth one read against ADR-0053 before the text is rewritten.

Dedupe

REST page walk over the 1000 most recently updated objectstack items (oldest updated_at 2026-09-20). field-types.md|mdx near currenc ⇒ only objectstack#19847 (a closed PR about format, not currency). Currency resolution ⇒ 0. currencyMode near skill|docs|field-types ⇒ 0. per-record { value, currency } ⇒ 0. Must-hit control currency ⇒ 60 hits.

Dedupe words: field-types skill currency resolution · currencyMode dynamic per-record value currency · currency field bare number docs · defaultCurrency tenant default mode

Addendum for whoever carries this card, from the objectui domain:ui seat #1 (session_01BA3nKVUwKQJf8DBxrSVtNC), 2026-09-25T03:33Z. ⛔ No label, grade or state is changed.

The contract review of PR objectstack-ai/objectui#10461 (boundary flag ③2) names a third page with the same drift: content/docs/data-modeling/fields.mdx. Its example authors currencyConfig: { currencyMode: 'dynamic', defaultCurrency: 'USD' } without saying that, under dynamic, USD is not the displayed currency. Once objectstack-ai/objectui#10461 lands, the renderer shows the tenant currency there. The runtime half of the same mode rule is filed separately as #20091 (service-analytics).

Triage: lands in skills/objectstack-data/rules/field-types.md (:183, 「'dynamic' = per-record { value, currency }」, and the "Currency resolution (ADR-0053)" paragraph at :189, on origin/main a8bcce6) ⇒ domain:skills, with content/docs/data-modeling/field-types.mdx (:155, "Whether currency is per-record or fixed") and content/docs/data-modeling/fields.mdx (the addendum 5826233021) taken by the same claim as a declared cross-domain surface; rationale: teaching text that contradicts the spec — a currency value is a bare number in both modes (CurrencyValueSchema is @deprecated for exactly this), and defaultCurrency is the field's currency only under currencyMode: 'fixed'. The North Star counts a wrong sentence in AI-facing docs and skills as a product defect; runs but teaches wrong ⇒ p2.

Triage seat #6015 · session_01CRZSc7dU8oDStbTbSwhuZe · 2026-09-25T04:54Z. ⛔ Not a claim, ⛔ not a dispatch. Read: this card and its one comment, and origin/main. Dedupe over 1,113 cards (open, plus closed since 2026-09-18): currencyMode → 4 hits (this card; #20091, its runtime sibling; #8345 and #20011, other questions).

Execution notes

1. Two PRs: skills/** is a governed surface (Tier H, human approval), the two content/docs pages are not. Land them separately so the docs fix does not wait on the approval.
2. Re-derive every sentence from the spec, ⛔ not from the renderer: bare number in both modes; fixed pins defaultCurrency; otherwise the tenant default applies. Read "dynamic (user selectable)" in the spec's own describe against ADR-0053 first, as the card says.
3. Sibling finding(service-analytics): a measure's currency is resolved without currencyMode, so a dynamic field's defaultCurrency shows on analytics faces while field faces show the tenant currency #20091 (service-analytics, the runtime half of the same rule) is a separate lane; no serial constraint between them.

Teaching now, re-derived from the spec: value is a bare number in both modes (ADR-0104 D1), never `{ value, currency }`; `fixed` pins the column to `defaultCurrency`; `dynamic` (default) displays the tenant `localization.currency` setting and `defaultCurrency` is not the displayed currency; neither ⇒ plain number; a measure's own `currency` wins. Mechanism assumptions measured: (a) HELD — at fa00ebf4 the example comments sit at :182–:183 and the paragraph at :189–:193 (diff hunk `@@ -179,18 +179,18 @@`); (b) HELD, resolved — `docs/adr/0053-*` is `0053-date-and-datetime-semantics.md`, 0 currency hits; of 14 ADRs matching `currency` only ADR-0104 governs a currency rule (D1 value shape); no ADR and no `cloud ADR-NNNN` governs the display order, so the paragraph cites ADR-0104 D1 for the shape and DROPS the ADR-0053 citation (the tenant default is named by its producer, the `localization.currency` setting in `packages/services/service-settings/src/manifests/localization.manifest.ts`, whose header calls the manifest an 'ADR-0053 Phase 2 follow-up' — which is how the number was borrowed); (c) ADR silent — no ADR, key or runtime seam names where a per-record currency would be selected, so the skill teaches only bare number + tenant default and the 'dynamic (user selectable)' gap is in PR A `## Acceptance notes` with carrier; (d) PARTLY FALSIFIED — `check:skill-examples` is opt-in by an `os:check` marker above the fence and `field-types.md` carries zero markers, so it type-checks nothing in that file (green regardless: '259 prose examples type-check across 3 surface(s)'); the token ratchet read 3158/3158 (headroom 0) before, 3157/3158 after — the file had zero headroom, so the rewrite was paid inside the same sentences; (e) HELD — docs gates run, all green.
