Full 'pnpm test' previously hung indefinitely (killed at CI walls,
misdiagnosed as teardown slowness). Two root causes found and fixed:
1. RightInspector.test.tsx called setSubject() during render with a fresh
object every pass -> infinite synchronous render loop (100% CPU spin,
blocks the event loop so no timeout can fire). Moved into useEffect.
2. Test QueryClients used retry:false but default gcTime (5 min) -> a live
GC timer per cached query kept workers from exiting. New shared
createTestQueryClient() with gcTime:0 adopted across all 7 test files.
Hardening so any future leak fails loudly instead of hanging:
- vite.config.ts: testTimeout/hookTimeout 10s, teardownTimeout 5s
- useManagedTimeout hook owns previously-bare setTimeouts in DigestBadge,
MetadataTable, RatificationCommandPanel (4 sites), CommandPalette focus
First-ever frontend CI lane (.github/workflows/workbench-ui.yml):
path-filtered to workbench-ui/** AND the workflow file itself,
pnpm install --frozen-lockfile + build + vitest, timeout-minutes 15.
Honesty fix: KeyboardHelp no longer advertises j/k, /, Enter (unbuilt
until R0d restores them registry-backed).
Route conformance test (ADR-0162 §6, executable): empty/error/loading
contracts asserted for Chat/Proposals/Evals/Replay; fixed the two gaps
it caught (ReplayRoute bare-div error branch -> ErrorState contract;
ArtifactList empty state gained a next action).
Result: 27 files / 181 tests pass, suite EXITS in 4.9s wall-clock
(was: indefinite hang).
