[finding] aggregate-capability.test.ts's header claims analytics.query() never throws on a non-2xx — the installed client throws, and the tests below depend on it

Found while fixing #5721 (PR #5952). Not folded in: it is a different defect class from that card's status-vs-code misclassification — a stale present-tense claim in a docstring — so it is filed rather than repaired as a rider.

The claim

packages/data-objectstack/src/aggregate-capability.test.ts, file header ("WHY THIS EXISTS"):

@objectstack/client's analytics.query() returns res.json() WITHOUT checking res.ok, so a non-2xx never throws — the error body arrives where rows were expected.

What the installed client actually does

@objectstack/client@17.2.0 (dist/index.mjs): analytics.query does end in res.json(), but it gets there through this.fetch(...), and that wrapper throws on !res.ok — decorating the error with code (flattened from errorBody?.code ?? errorBody?.error?.code), httpStatus, message, details — so res.json() is unreachable for a non-2xx.

Measured, not inferred: the ablation run for #5721 shows the client logging HTTP request failed: POST …/analytics/query -> 404 and the adapter's catch branching on the decorated error. Every test in the file below the header, old and new, depends on the throw — the first one (404 … falls back instead of returning an empty result) passes because the throw reaches the catch; on a client that truly did not check res.ok, aggregate() would return [] and that test would fail.

Why it is worth correcting rather than leaving

The paragraph reads as a present-tense description of the client, sitting directly above tests that assume the opposite. It is exactly the kind of note an agent reads and trusts before touching this file — and the conclusion it invites ("non-2xx arrives as data, not as a throw") would send someone to add row-shape guards to aggregate()'s success path instead of reading the catch.

The paragraph is presumably true history — the defect it describes is real and is what the file was written for. The correction is a tense/attribution fix (name the client version or the era the claim describes), not a deletion.

Where

packages/data-objectstack/src/aggregate-capability.test.ts — file header, first paragraph.
Reference: the wrapper is ObjectStackClient.fetch in @objectstack/client's dist; analytics.query is the caller.

Concentrated triage round: finding → pm:queue, Task, domain:ui stands. Stale header claim: the installed @objectstack/client@17.2.0 throws on !res.ok inside this.fetch, so the header's "never throws on a non-2xx" rationale is false while the tests beneath it depend on the throwing behaviour. Comment-only rewrite of the "WHY THIS EXISTS" header to the measured mechanism. Size: S mechanical, sonnet floor.

Branch: claude/issue-5954-aggregate-capability-header

Dispatched at triage's own sizing — Task, S, mechanical, sonnet floor — and the developer is told the change is comment-only: the header's stated rationale is what is false, not the tests beneath it. ⛔ The order explicitly forbids "fixing" the tests to match the header, which is the inverted repair available here.

Declared file face for the cross-lane in-flight check: aggregate-capability.test.ts and its module header. No other in-flight card in this lane touches it.

So analytics.query's own res.json() call is unreachable on a non-2xx: the header's claim was the exact opposite of what happens.

ACCEPT — PR #6728 (`278e5095`), marked ready

domain:ui execution seat, session session_01CRJge11jso9TpXRWFt1Z49. Diff reviewed independently before the report arrived; the report then confirmed every reading and answered the one question the order deliberately left open.

⭐ The judgement worth keeping: it did NOT delete the stale paragraph

My order said to "rewrite the header to say what actually happens." Executed literally, that deletes the old paragraph — and the old paragraph is the reason this file exists. It describes the defect the file and classifyAnalyticsFailure were built to pin against: a client returning res.json() without checking res.ok, an error body arriving where rows were expected, the row parser producing [] and returning it as a result, and a KPI rendering a confident zero on a deployment without @objectstack/service-analytics.

The developer kept it and relabelled it explicitly as history — "That defect is why this file and classifyAnalyticsFailure exist; it is no longer what the installed client does, so it is recorded here as history rather than as the present-tense mechanism."

⇒ A stale explanation and an origin story can be the same paragraph. Correcting the tense is the fix; deleting the text would have thrown away the only record of why the pins are there. The order should have said so, and the next one of this shape will.

The measurement, done rather than inherited

The order told the developer not to copy triage's sentence but to establish it. It did:

Installed client: @objectstack/client@17.2.0, read from two sources that agree — pnpm-lock.yaml and the resolved node_modules/.pnpm entry's own package.json. Not the package.json range.
Throw site, located to the line: ObjectStackClient.fetch in the installed dist/index.mjs (class at 614, method at 4272) checks !res.ok, flattens the error body (errorBody.code falling back to errorBody.error.code), builds a decorated Error carrying httpStatus/message/details, and throws before returning. analytics.query (lines 921–929) calls this.fetch(...) and only then res.json() — so its own res.json() is unreachable on a non-2xx.

⇒ The header's claim was not merely imprecise, it was the exact opposite of the mechanism, and every test below it except the two 2xx cases depends on that throw reaching the adapter's catch.

The changeset question was answered by reading the gate, not guessing

The order refused to tell the developer whether a test-only change needs a changeset and required it to read the gate. It did: packages/data-objectstack is in .changeset/config.json's fixed group and the diff sits under src/, so check-changeset-presence.mjs requires a declaration even for test-only changes — a rule stated in that script's own header. The empty frontmatter form is that gate's documented no-release exemption, and both check-changeset-presence.mjs and check-changeset-no-major.mjs exit 0 on it.

Scope held

git diff --stat shows the docblock and the changeset, nothing else. Zero test code, zero assertions touched — which was the one prohibition in the order, since the inverted repair (bending the tests to satisfy a stale comment) was the available wrong answer here.

⭐ And the package-directory vitest form fired this repo's own guard (objectui#3378's false-green trap) on first try; it was correctly read as a wrong invocation, not a red gate, and re-run from the repo root. That is the second developer this round to hit that guard and read it right.

Landing

PR #6728 marked ready. Checks are still running; it will be armed on a full table with every row green — in_progress is not a green.
