counterState and dbStatus each become one statement (the database size is memoised for a minute), the REST guard hands back the event it resolved instead of handlers looking it up again, the finished-runner count only runs when it can change the capability set, the course-map window preview shares the tile render gate, and controlCompletionStatus loads only the requested course's runners and their cards.

Four full stacks on a 4 vCPU runner ran every shard at half speed and pushed 5 s expect budgets over; the shard count now follows the core count. The runner create/edit/delete test derives its name and card from the retry index so a slow first attempt cannot turn into a duplicate-card dialog on retry, and the two long course-editor tests declare themselves slow instead of racing the 30 s test timeout.

Stacked on #28 (base branch); GitHub retargets to

Commit 1 — performance sweep (
docs/perf-polling-and-auth-round-trips.md). Follow-up to the Cloud Run log review: the recurring slow endpoints were all polls or per-request plumbing.competition.counterState(every 5 s/tab): 9 sequential queries → 1 statement with scalar subselects.competition.dbStatus(every 3 s/tab, public): 3 queries → 1;pg_database_size()memoised 60 s (ttl-memo.ts).assertRestAccessnow returns the resolvedEventRefso handlers stop looking the slug up twice;countFinishedRunnersonly runs when it can change the capability set (finishedCountMatters— date already past or grants already cover the completion caps ⇒ skip). Semantics unchanged./api/maps/:nameId/window.pngrasterises under the sharedrenderGate()with the same 503/Retry-Afterbehaviour as tiles, so layout previews can't stack on top ofMAP_RENDER_CONCURRENCYtile renders.course.controlCompletionStatus(every 15 s) loads only the requested course's runners and the cards they carry; one regex per control.online-input-config.spec.tsthat was flaking under load.Commit 2 — CI E2E failures. Every
mainrun since #26 has failed the E2E job (blockingpublish). All failures were timeouts: four full stacks on a 4 vCPU runner ran each shard at half speed (6–10 min vs 3–5 locally).scripts/e2e-sharded.mjs: default shard count is nowmin(4, floor(cores/2))— 4 on a dev box, 2 on a GitHub runner.E2E_SHARDSstill overrides.phase2.spec.tscreate/edit/delete: names and card number derive fromtestInfo.retry, so a slow first attempt no longer leaves a runner that makes every retry hit the duplicate-card dialog (the one deterministic failure in all three runs); list waits raised to 15 s.test.slow().docs/e2e-sharding.mdandAGENTS.mdupdated.Test plan
