analytics: a derived sum over one fixed-currency code reaches the wire with no currency code, though the docs say it carries that code

domain:server#4 · os-elon-musk · session_016WV4d1Np3hU7RQnA13YZcL

Filing gate: ① read beside a ruled card by the contract review of PR #28043 (#28019, record 6520682484), which asked for it as its own card. Filed by domain:server seat 4. ⛔ Not a claim. No grade: triage sets the lane and grade.

What the code does (read, not run)

service-analytics/src/measure-currency-coherence.ts resolvedOf knows at compile time that a derived sum / difference whose operands all resolve to one fixed code is an amount in that code.
enrichResultColumns (service-analytics/src/analytics-service.ts ~L3194–3209) reads a measure's metadata through m.field. A derived measure has no field, so meta is undefined, and monetary = !!mc.currency || meta?.type === 'currency' is false unless the measure restates currency.
The derived column is minted as a bare type: 'number' field (dataset-executor.ts ~L1335).

So a derived sum of two EUR-fixed measures with no currency of its own reaches the wire as an unlabelled number. Only restating currency: 'EUR' labels it.

Where the docs say otherwise

content/docs/data-modeling/currency.mdx ~L178: "a derived sum or difference over one fixed code carries that code". True of the compile-time resolution, not of the response.

Wanted (route is triage's)

Either the column chain labels a derived sum or difference with the one fixed code its operands resolve to (so the page is true), or the page says the author restates currency to label it. PR #28043's refusal message currently prescribes the second reading ("restate the operands' code, or delete it; the column then carries no currency code"), and should move with whatever is ruled.

Dedupe

Read open titles for derived + currency, fixed code, enrichResultColumns: #28019 only (the compile-time refusal, PR #28043). New.

⛔ Not a claim.

Read fresh. The docs already say that a derived sum over one fixed code carries that code, so the wire is the defect. enrichResultColumns takes the derived measure's currency from the same resolvedOf reading the compile guard uses, with no second resolution, and the column is minted monetary. Pin it.
It is the analytics(dataset): a derived measure that declares its own currency over operands resolving to one fixed code compiles and prints that code's amounts labelled as the declared currency #28019 family, serial behind PR fix(service-analytics): refuse a derived measure currency that contradicts its operands' fixed code #28043 (the same module).

Domain: domain:server
Seat: domain:server#3
File surface: packages/services/service-analytics/src/analytics-service.ts (enrichResultColumns), packages/services/service-analytics/src/measure-currency-coherence.ts (exposing resolvedOf's reading, no second resolution), packages/services/service-analytics/src/dataset-executor.ts (the derived column's minting) if needed, tests beside them, .changeset/*. If PR #28043's refusal message prescribes the opposite reading, it moves with this rule (same module).
Container & model: M, mode:thread, model: opus (TIER_DEFAULT), effort: high
Clause-②: no (the response comes to say what content/docs/data-modeling/currency.mdx ~L178 already declares; the dev confirms from the diff and cites that text)
Metadata-protocol: none
Responsibility: service-analytics labelling a derived sum / difference column with the one fixed code its operands resolve to, from the compile guard's own reading.
Thread-read: 6521075848
Premise: holds on main @ 8cb8c7f4: monetary = !!mc.currency || meta?.type === 'currency' (analytics-service.ts:3204) reads metadata through m.field, which a derived measure lacks.
Serial constraints cleared: blocker PR #28043 merged 2026-10-30 11:20Z, so pm:blocked comes off in this label write. No open PR touches this surface at claim time (checked against the open PR list).
Dispatch-note: p2, unblocked by the seat at claim.
