A parity walk over GET /api/analytics on an account with a full record
(record-fixture.ts, reusable by the other read routes): an unknown slice,
the summaries slice and the default body cold and warm, the modules off, a
second language with a personal blood-pressure target, an empty account and
an anonymous call. Background work a request leaves running is settled
before the next one. The blood-pressure fast path's rollup row counts are
left out of the pinned wide event: they follow the rollup tier's coverage,
not the code, while the answer they fed stays pinned in the body.
