The new backup, dump and deletion files were unknown to the duration
sequencer and gathered in one shard, which ran past its job timeout
while the other three finished in under fifteen minutes.
The per-account preview switch was kept for the topic overview pages,
which were dropped before they shipped. Its one flag was stored, served
and backed up, and read by nothing; the column-reader audit listed it as
a pending consumer that will not come.
Removed completely:
- `/api/settings/preview-features` (GET, PATCH) is retired: it answers
410 Gone with `meta.errorCode: route.retired` and `removedIn: 1.46.0`,
and the contract publishes it under Retired. The route, its validation
schema, the `PreviewFeatures` OpenAPI schemas and the settings module
are deleted.
- Migration 0485 drops `users.preview_features_json` under a bounded lock
wait, with the retry marker.
- The backup no longer writes the field. A file from v1.44 or v1.45 that
carries it still restores: the schema accepts it and no codec reads it,
so nothing is refused or written for it. The backup-parity goldens
lose the field and apply one setting fewer.
- The data-wipe plan entry and the sharing-surface actor entry go with
the route (frozen count 273 -> 272).
No client build reads the route: neither iOS repository nor any local
checkout references it.
Thirteen of the table's files had been deleted or renamed since it was
written. The entries were dead weight; nothing reads a timing for a file
that is not there.
Vitest's --shard cut the file list into slices of equal length, which gave
the integration shards 954 s to 1 449 s. A sequencer now deals files out by
their measured duration, plus a fixed per-file cost for import and setup,
longest first to the shard with the least work, and starts the longest files
first inside a shard. Timings live in tests/durations/*.json and are
regenerated from Vitest JSON reports with scripts/test-durations.mjs; every
CI shard uploads its report.
Integration shards run three workers each, one cloned database per worker.
The unit suite runs as three projects decided per file from its source:
guards and unit share a module graph inside a worker, isolated keeps a fresh
one for every file that mocks, spies, stubs or resets. In CI it is three
duration-balanced shards next to a job for lint, format, types and the
OpenAPI drift check.
The required check names stay as they were. "Lint, Typecheck & Test" is now
the job that answers for the static checks and every unit shard, the way
"integration" already answers for its shards. The browser-install guard
recognises a direct, flags-only vitest run as a run of the unit suite.
