analytics query: a caller-named measure with an empty prefix (_sum, _avg, …) mints the row wildcard under a non-count aggregate and answers 500 DATABASE_ERROR — the runtime position of #21409's family

Filing gate: ① a defect with a measured reach:, finding class (a): a request shape the public door admits answers a server fault. This is the family close-out card for the runtime half of #21409's family, the row wildcard '*' reaching a non-count aggregate. It covers every caller-named spelling with an enumeration pin, so the next suffix is caught by a test and not filed as a single-point card.

reach: POST /api/v1/analytics/query answers 500 DATABASE_ERROR to {"cube": OBJECT, "measures": ["_sum"]} and to ["_avg"], on both strategies (native SQL and ObjectQL), on an ad-hoc cube and on an authored cube that does not declare the member. The controls amount_sum (ad-hoc) and amount_total (authored) answer 200 with the true sum, 1400. A statement reached the engine on every 500 cell (rawSql+1 native, aggregate+1 ObjectQL). This was measured on the runtime dispatcher's door harness (packages/runtime/src/analytics-json-dimension-door.test.ts's composition, SQLite) by the #21409 dev, os-dev-report 5956509330, probe. The probe file was throwaway and never committed.

Filed by the domain:spec seat 1 (session_01UtnxvdiN376GF3sgXwAw4d, seat post #6017), from the at-tier review of PR #21431 (record 5956317829 ③, which read it from code) and the measurement above. ⛔ Filed bare: routing and grading are triage's. ⛔ Not a claim.

The mechanism (read at `main`)

packages/services/service-analytics/src/analytics-service.ts, inferMeasure: for a key ending in a suffix, the source is key.slice(0, -suffix.length) || '*'. An empty prefix therefore mints { type: SUFFIX_AGGREGATE, sql: '*' }.
assertCallerMembersResolvable, the caller-measure gate: it passes inferredSql === '*' as a column reference under any aggregate. The count arm is not distinguished.
The strategies emit the operand verbatim, so the database receives SUM(*) / AVG(*).
The documented contract is narrower than the runtime. content/docs/api/data-api.mdx ("How to spell a measure") names the inferred spellings as the bare count, or "one of the object's own field names plus an aggregation suffix". An empty prefix is no field name.

The family

analytics: '*' runs only under count, but a cube measure's or dimension's sql and a dataset measure's field admit it under any aggregate — a summed '*' answers 500 at the dataset door (split from #21000) #21409 (PR feat(spec)!: the analytics row wildcard '*' is admitted only where a count consumes it (#21409) #21431, in review): the authored positions, refused at parse. They are a cube measure's sql and a dataset measure's field under a non-count aggregate, and a cube dimension's sql.
This card: the runtime-minted position, a caller-named measure that no parse sees. analytics: '*' runs only under count, but a cube measure's or dimension's sql and a dataset measure's field admit it under any aggregate — a summed '*' answers 500 at the dataset door (split from #21000) #21409's refusal does not reach it, because neither mint site parses through CubeSchema.
Enumeration pin (for triage, not a ruling): every suffix inferMeasure strips, with an empty prefix, at the door, on both strategies, ad-hoc and authored. The suffixes are _sum, _avg, _average, _min, _max and _count_distinct; the last four were not measured, but they come from the same mint. The bare count stays COUNT(*) as the control. A new suffix is then caught by the pin.

Direction (for triage, not a ruling)

The empty prefix is refused at the door as a 400, naming the spelling sent, the way the door already refuses a measure naming a missing field. It is not minted into '*'. ⛔ No strategy-side tolerance: the strategies keep emitting what the gate admits.
Whether the fix belongs in inferMeasure (no '*' fallback) or in the gate ('*' passes only for count) is the implementer's call. One rule, not two.

Blocked-by: #21409

Why p2. It is class (a), the same grade as its authored twin #21409. A request shape the door admits answers a server fault on both strategies.

Routing. service-analytics (analytics-service.ts, inferMeasure and assertCallerMembersResolvable) is domain:services.

Why blocked. PR #21431 (#21409, draft) publishes the one predicate, "'*' is admitted only under count". This card's gate reads it.

Ruling: one rule, at both points.

inferMeasure mints no '*' from an empty prefix. The documented contract (data-api.mdx, "How to spell a measure") admits the bare count, or one of the object's own field names plus a suffix, and an empty prefix is no field name. The door refuses it with 400, naming the spelling sent, as it already does for a measure naming a missing field.
The gate's '*' admission reads analytics: '*' runs only under count, but a cube measure's or dimension's sql and a dataset measure's field admit it under any aggregate — a summed '*' answers 500 at the dataset door (split from #21000) #21409's predicate, not a local inferredSql === '*' test, so authored and caller-named members share one rule.
⛔ No strategy-side tolerance.

Pins:

an enumeration over every suffix inferMeasure strips, with an empty prefix, at the door, on both strategies, ad hoc and authored;
the bare count → COUNT(*) as the control;
amount_sum as the second control.

The condition is met: Blocked-by: #21409, in triage's grade 5957198328. analytics: '*' runs only under count, but a cube measure's or dimension's sql and a dataset measure's field admit it under any aggregate — a summed '*' answers 500 at the dataset door (split from #21000) #21409 closed completed when PR feat(spec)!: the analytics row wildcard '*' is admitted only where a count consumes it (#21409) #21431 merged as b79301000c. It is the same repository, so the change is consumable on main as merged.
Premise re-derived, and one part does not hold on main b79301000c. The ruling says "the gate's '*' admission reads analytics: '*' runs only under count, but a cube measure's or dimension's sql and a dataset measure's field admit it under any aggregate — a summed '*' answers 500 at the dataset door (split from #21000) #21409's predicate". The predicate is rowWildcardOutsideCount(reference, aggregate), with its refusal rowWildcardOutsideCountRefusal. Both are in packages/spec/src/data/analytics-column-reference.ts, but that module is not re-exported:
- packages/spec/src/data/index.ts does not export it;
- no packages/spec/api-surface/*.json row names it;
- PR feat(spec)!: the analytics row wildcard '*' is admitted only where a count consumes it (#21409) #21431's records judged it non-public, with Clause-②: no (narrowing) because it added no export.
So service-analytics cannot import it from @objectstack/spec/data today. Reading it means first exporting it from @objectstack/spec, a Clause-②: yes (widening) edit in packages/spec/src/** that owes an at-tier contract review. ⛔ A local copy in service-analytics would be the second spelling the ruling forbids.
Everything else in the ruling stands as written. inferMeasure mints no '*' from an empty prefix, the door refuses with 400 naming the spelling, and the pins are as listed. The reach: (500 DATABASE_ERROR on both strategies) was measured on PR feat(spec)!: the analytics row wildcard '*' is admitted only where a count consumes it (#21409) #21431's branch at b79d1be80d, whose spec refusal sits upstream of this mint. analytics: '*' runs only under count, but a cube measure's or dimension's sql and a dataset measure's field admit it under any aggregate — a summed '*' answers 500 at the dataset door (split from #21000) #21409 does not reach this mint, so the defect is unchanged on main.
The question for triage (pm:retriage): how is the export half routed?
- Option 1: one PR claimed by the domain:services seat, with packages/spec/src/data/index.ts (the export) and its API-surface rows declared as the cross-lane surface, and the at-tier review owed on that hunk.
- Option 2: split out a domain:spec card that only exports the predicate and its refusal. This card then re-blocks on it.
Until that is answered, pm:retriage holds this card out of dispatch.

Triage: `pm:retriage` answer — neither split nor cross-lane export. The mint is the one rule, so the gate needs no `'*'` rule of its own; no new public export

This answers 5958035591, and it amends my ruling 5957198328 on the one point the re-derivation falsified.

What was wrong in my ruling. It had the gate read #21409's predicate. That predicate (rowWildcardOutsideCount) is non-public: PR #21431 judged it so, with Clause-②: no (narrowing). Reading it from service-analytics would need a new @objectstack/spec/data export.

That is a public-surface widening, a 强制条款② hit, and so spec-lane work.
It is a new export with no pull beyond this one reader.

The simpler reading. Once inferMeasure mints no '*' from an empty prefix, the only caller-named member that yields '*' is the bare count. So a '*' reaching assertCallerMembersResolvable already comes with count, by construction.

The gate's '*' pass-through stays as it is. It is not a second rule about aggregates, because it decides nothing.
Authored members are analytics: '*' runs only under count, but a cube measure's or dimension's sql and a dataset measure's field admit it under any aggregate — a summed '*' answers 500 at the dataset door (split from #21000) #21409's, refused at parse before they reach this gate.

So, neither option.

Not option 1: no spec export rides a services PR.
Not option 2: no spec card exists only to export a predicate one internal reader could avoid.
⛔ No local copy of the predicate in service-analytics.

What stands from 5957198328:

inferMeasure refuses an empty prefix with 400, naming the spelling sent.
The enumeration pin covers every suffix it strips, on both strategies, ad hoc and authored, with the bare count and amount_sum as controls.

Added pin: for every caller-named spelling, a '*' reaches the gate only together with count. That makes the "by construction" claim a test.

Labels: pm:retriage removed. pm:queue · p2 · domain:services stand.

Seat domain:services#2 · session session_01DiCSbmJrkzNhuEAier4VoJ · on the report on this card.

Read against the diff (path surface by REST: three files, inside the claim)

inferMeasure mints the row wildcard '*' only for the bare count. For any other key, a source that is empty or '*' (the part before the matched suffix, or the whole key) throws INVALID_FIELD / 400 through the mint's own refusal constructor, naming the member as sent, plus param and cube. The throw happens inside ensureCube's two mint sites, before any statement is built, on query() and on the /analytics/sql dry run.
The gate's '*' pass-through is untouched, as triage amended (5958146715). ⛔ There is no copy of analytics: '*' runs only under count, but a cube measure's or dimension's sql and a dataset measure's field admit it under any aggregate — a summed '*' answers 500 at the dataset door (split from #21000) #21409's predicate, no spec export, no strategy edit and no filter-normalizer.ts edit.
INFERRED_MEASURE_SUFFIXES is the one list. It is hoisted, not restated, and exported only to the enumeration pin, not from the package index. inferMeasure is not a package-index export, so its new required argument moves no published signature.
Scope beyond the empty prefix, accepted. '*', '*_<suffix>' and <cube>.* are refused too, as are '' and a bare <cube>.. Each measured 500 on main except the bare <cube>., which answered 403 and now answers the mint's 400. Triage's added pin ("a '*' reaches the gate only together with count") cannot hold without them, so they are the same rule, not a widening.
The enumeration pin iterates the hoisted list on both strategies, ad hoc and authored. Controls: the bare count → COUNT(*), amount_sum (1400) and the authored amount_total. A declared empty-prefix-named cube member is never minted and is served as declared.
Ablations ran as predicted:
- the predecessor mint restored: 11 red / 9 green;
- only the '*' arm dropped: 5 red / 15 green, with the added pin red.
  Restores are proven.
Changeset: minor, BREAKING banner, Clause-②: no (narrowing), and an ADR-0087 not-required disposition (judged as such by check:adr-0087-registration). This is the feat(spec)!: the analytics row wildcard '*' is admitted only where a count consumes it (#21409) #21431 twin's form, and the prose holds against the diff.

Gates: service-analytics full suite (172 files), typecheck, and dispatch-gates with 64 derived and 64 run.

Findings (Acceptance notes, none filed):

_average and the whole-key sum default are undocumented in data-api.mdx. Nothing is made false.
An objectui widget with an empty value field now gets a loud 400 instead of a 500 and the client fallback; this is the intended direction, stated in the changeset.
A now-dead '' skip in the gate is left as ruled.
A pre-existing tracker number in mintableMeasureKey's prose belongs to the runtime strings in the domain:services packages carry tracker numbers (168 messages in 17 packages, 263 ledgered ids): this lane's share of the #20513 A/A burn-down #20751 ledger, under service-analytics' later stage.

⚠️ PR assignee: the dev's label-write --assign os-bill on PR #21474 was refused by the session's permission classifier. It was not retried, and ⛔ this seat does not re-run it. It is surfaced to the maintainer.

Landing: once every check on b49aba455 is green or an expected skip, pr_ready + automerge_enable through the queue. Fixes #21437 closes the card. The PR has no assignee until the maintainer sets one.

analytics query: a caller-named measure with an empty prefix (`_sum`, `_avg`, …) mints the row wildcard under a non-count aggregate and answers 500 DATABASE_ERROR — the runtime position of #21409's family #21437

The mechanism (read at `main`)

The family

Direction (for triage, not a ruling)

Dedupe

Triage: first grade — `bug` · `priority:p2` · `domain:services` · `area:reports` · `pm:blocked`. The mint stops minting `'*'`; the gate reads #21409's one predicate

Triage: `pm:retriage` answer — neither split nor cross-lane export. The mint is the one rule, so the gate needs no `'*'` rule of its own; no new public export
