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).
Brief 4 of the Wave 1 evidence spine — wire the evidence-context architecture
so every route can project into one shared evidence manifold.
Command registry (1A):
- commandRegistry.ts: useSyncExternalStore-backed command store with a cached
snapshot (referentially stable to avoid render loops); useCommands /
useCommandRegistry; recent-items in localStorage (last 10).
- CommandPalette.tsx: reads from the registry; all ten routes are navigation
commands (was Chat/Proposals/Evals hardcoded); fuzzy filter, recent section,
shortcut badges; Router/Fallback split preserved.
- useGlobalKeyboard.ts: Cmd+K palette, Cmd+I inspector, Cmd+1-0 routes, ? help.
Evidence drawer (1B):
- evidenceContext.tsx: EvidenceSubject union (turn|proposal|artifact|
eval_result|none) + useEvidenceSubject hook + EvidenceProvider above the
router Outlet so inspector state persists across route transitions.
- RightInspector.tsx: five evidence projections (was a null stub); reuses the
Brief 2 primitives (MetadataTable, DigestBadge, Timestamp, badges).
- Shell.tsx: visibility driven by inspectorOpen (collapsed by default); no more
hardcoded collapsed=true.
- KeyboardHelp.tsx: shortcut reference dialog.
- TopBar.tsx: palette open state lifted to Shell via props.
Tests: evidenceContext + RightInspector specs added; CommandPalette keyboard
contract updated for the ten-command navigation set (clamp at both ends).
Deferred (noted in spine doc): per-route register()/setSubject call sites,
action-commands (run eval / copy hash), resizable inspector width.
Verified: tsc -b + vite build green; affected specs pass per-file.
