skills/docs (currency): four texts teach that a dataset measure's own currency always wins over a fixed field; after #27579 a contradicting code is refused

Filing gate: ① skills and docs text that will contradict the runtime at named locations. Found by the #27579 card thread (PR #27991) and filed by the domain:server seat, because these files are outside the server lane's surface. ⛔ Not a claim.

Drift (lands with PR #27991)

PR #27991 (#27579, maintainer ruling 6486427200, ADR-0144 Open item 12 letter A) adds two fixed-currency refusals to dataset compile, both DATASET_INVALID / 400:

a measure currency that differs from its aggregated field's fixed code (restating the same code stays legal);
a derived measure, any op, whose monetary operands resolve to two different fixed codes.

Not judged, unchanged: a fixed code against the tenant currency, and a measure currency over a dynamic field.

These texts teach the old rule or only the record-mode refusals from #27338:

skills/objectstack-data/rules/field-types.md:185: "Under 'fixed'/'dynamic' a measure's own currency wins." This becomes false for a contradicting fixed code.
skills/objectstack-ui/rules/dashboards.md:298-300: the currency-chain comment.
content/docs/data-modeling/currency.mdx:165-168 (Roll-ups and datasets): lists only the record-mode refusals.
content/docs/api/data-api.mdx:498-505: the currency chain.

Grep used: git grep -n -iE "measure.{0,40}currency|currency.{0,40}measure" -- 'skills/**' 'content/docs/**'.

Wanted

State the two fixed refusals and their fixes next to the record-mode ones, in the words each file already uses. The fix for the first is to delete the measure's currency, so the column takes the field's code. The fix for the second is to derive from measures in one currency, or to drop the operand in the other. Keep the two not-judged cases explicit.

⛔ Do not edit before PR #27991 merges. Until then the texts are still true.

Dedupe

#27579 / PR #27991 (runtime), #27338 (record-mode arms), epic #8345 (the ADR-0144 dated note stays with the epic PM). No open card covers these lines.

⛔ Not a claim.

Read fresh. The texts stay true until PR fix(service-analytics): a dataset refuses a measure currency that contradicts its field's fixed code, and a derived measure across two different fixed codes #27991 merges, so it is blocked (Blocked-by: #27991 is now in the body).
Granted (SKILL.md 跨域例外路径): the domain:skills lane claims the one PR, and the claim declares content/docs/data-modeling/currency.mdx and content/docs/api/data-api.mdx (devx). One rule is taught in all four places, in each file's own words. Tier H for skills/**.
documentation, pm:blocked.

Responsibility: after PR #27991 (#27579) dataset compile refuses a measure currency that contradicts its field's fixed code and a derived measure mixing two fixed codes, but four texts still teach that a measure's own currency always wins, so an AI author writes a dataset the compiler refuses.
Thread-read: 6516910471 (triage: p2; cross-domain exception for the two devx docs; one rule in four places in each file's own words; Tier H)
Premise: holds (origin/main f4826f810: field-types.md:185 「a measure's own currency wins」; PR #27991 merged 2026-10-30T07:17Z, so Blocked-by: #27991 is spent and the card leaves pm:blocked with this claim)
Serial constraints cleared: no open PR touches these four files at claim time (#27958 edits other objectstack-data / objectstack-ui files; #27954 edits datasources.md). Landing tier is read off the register at PR time; triage graded Tier H.

ACCEPT → PR #28015 (register Tier H, skills/**; contract review PASS on head 946f6b4; CI green; approvers requested). Awaiting a GOVERNED_APPROVERS approval, then the seat lands it. Runtime gap found in review → #28019.

domain:skills#2 · os-elon-musk · session_016WV4d1QkPVVzNz3FJqb2iS

Landed: PR #28015 merged (21b2a103e, 2026-10-30T08:35Z), Tier H, approved and queued by os-zhuang, on contract review PASS 6518287213 (ACCEPT 6518288120). pm:dispatched is stripped with this note.

From this commit the skills and docs no longer teach that a dataset measure's own currency always wins over a fixed field. They teach the two fixed-currency refusals that #27579 introduced. The runtime gap the review surfaced, derived-measure currency, is filed separately as #28019 for the server lane. Nothing further owed on this card.
