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.
Replace blanket no-mutation language with the admitted-corridor rule: ADR-governed path, visible preconditions, auditable telemetry, and replay evidence before action.
Math ratification is documented as the first admitted proposal corridor. Corpus, pack, workflow, arbitrary file, and unadmitted proposal mutation remain forbidden.
SplitPane, TabBar, MetadataTable, DigestBadge, Timestamp, SearchInput.
All token-driven, keyboard-navigable, ARIA-accessible, dark theme,
motion-respectful. No new dependencies — TabBar uses native ARIA
semantics instead of @radix-ui/react-tabs.
PreviewPage updated with all six components in representative states.
Section 1C checked off in wave-1-evidence-spine.md.
Append-only JSONL journal records the exact ChatTurnResult envelope returned by /chat/turn with stable turn_id, trace_hash, all three surfaces, verdicts, and deterministic journal_digest.
GET /trace/turns and GET /trace/{turn_id} serve journal evidence for the Trace route frontend. Read model only; no teaching, pack, or journal-owned engine_state mutation.
* feat(workbench-ui): design system v1 scaffold
* fix(workbench): close R1 (GroundingSource enum coverage) + R4 (digest test)
R1 — Promote GroundingSource to a typed Literal in core/epistemic_state.py
so it has the same single-source-of-truth shape as ReviewState. The
existing epistemic_state_for_grounding_source() function already
enumerates the six labels (pack, teaching, vault, partial, oov, none);
this codifies them.
scripts/dump-enums.py now snapshots GroundingSource via the existing
literal_values helper. workbench-ui's enumCoverage.test.ts gains a
fourth assertion that the badge mapping matches the Python source
1:1. Adding a grounding-source value on the Python side without
updating the badge fails the build-time test loud — same discipline
as the other three enums.
R4 — Add an explicit DigestBadge test to StableJsonViewer.test.tsx:
asserts the badge text matches the SHA-256 prefix of the source bytes,
and clicking the badge copies the FULL digest (not the truncated
prefix). Recomputes the expected digest via crypto.subtle to avoid
hard-coding a hex string that could drift.
R2 (component-level reduced-motion enforcement), R3 (EmptyState
copy-CLI affordance), and R5 (`uv run core` packaging paper cut) are
deferred — R2/R3 become meaningful with W-027/W-029, R5 is a
packaging-layer concern outside this PR's scope.
Validation:
- pnpm test: 19 passed (was 17, +1 enum coverage, +1 digest test)
- pnpm build: clean
- pnpm test:enum-coverage: 4 passed
- core test --suite smoke -q: 67 passed
