docs/contributing/testing.md says which suite a test belongs in and why,
how to write a route test with the kit and what its contract check proves,
how the settings round trip and the integration database work, how the
shards are balanced and the timings regenerated, when to write a property
test, how the mutation floors are kept, and the flaky-test policy with the
quarantine format. Linked from the docs index.
scripts/bench/seed-large-account.ts (moved from scripts/, extended) writes
one synthetic account of ten years: 1,265,561 measurement rows across the
main types and five sources (Apple Health dense spot rows, Withings blood
pressure and scale, a weekly manual weight, three years of Oura nightly
values, 90 days of Nightscout CGM), `stats:` and per-sample cumulative rows,
nightly sleep stages, 3,020 workouts, 1,095 mood entries and three
medications with 3,285 intake events. Everything goes in through set-based
INSERT … SELECT generate_series; values and timestamps are functions of the
row index and `--anchor`, so a run is reproducible. The rollup tier is
folded with recomputeUserRollups, as the boot backfill does, and the tables
are analysed. About 80 s on the Mac mini.
scripts/bench/run.ts boots the production build once with every role (so
the queues exist), then measures against a web-only process under the
production heap ceiling: p50, p95 and max latency and SQL statements per
request (pg_stat_statements, read once nothing is in flight and the count
holds still) for /api/auth/me, the dashboard summary and snapshot, the pulse
series over 30, 365 and 3650 days, the day view, insights health status and
correlations, each cold (caches evicted by a one-row manual-sync ingest
before every request) and warm, plus a 5,000-row batch ingest as ten
requests of 500. It writes JSON and a markdown table.
docs/contributing/benchmarks.md describes the setup against a throwaway
Postgres in Docker with the production pg_stat_statements settings.
The UI standards drop working shorthand, state the spacing scale once in
section 2 (section 13 had listed an older scale without 2.5 and 3.5) and
use no em dashes. The v1.3 to v1.4 migration note no longer claims that
/settings#anchor URLs redirect to their section: the fragment never
reaches the server. A test holds both documents to this.
The binding UI rulebook (card anatomy, spacing scale, text colour,
tokens, primitive mapping, enforcement) lived outside the repository,
so a contributor could follow a code comment to a file they could not
open. It now lives at docs/contributing/ui-standards.md, every comment
that cited it points there, and the docs index and ui-guidelines.md
say which document wins when they disagree.
