Shay 80e02ce7de feat(workbench): sealed single-turn replay backend — GET /replay/{turn_id} (Wave R3)
Replaces the W-026 501 stub. Re-executes a journaled prompt in a sealed
fresh runtime (ChatRuntime(no_load_state=True): no checkpoint load, no
checkpoint write, no proposal lineage) and compares the envelope
leaf-by-leaf against the recorded TurnJournalEntry.

Design correction vs the scoping doc (amended in-doc): journaled turns
each ran in a fresh ChatRuntime(), never one continuous session, so
genesis-PREFIX replay would manufacture spurious divergence; shipped
basis is sealed_fresh_runtime_single_turn (O(1)). origin_state:
"unrecorded" — the journal does not record whether the original turn's
runtime loaded a checkpoint, so divergence is reported as nondeterminism
OR origin-state influence, never disambiguated.

- workbench/replay.py: pure comparison + injected executor; every
  TurnJournalEntry field classified critical/informational exactly once
  (exhaustiveness enforced by test)
- api.py: route wiring under _CHAT_TURN_LOCK; runtime failure -> 500
  runtime_unavailable, no comparison may be fabricated
- schemas: additive TurnReplayComparison/TurnReplayDivergence (W-026
  artifact-keyed pair retires with the frontend Replay Moment PR)
- tests: 10 obligations incl. tamper-prompt, tamper-leaf precision,
  no-execution-no-comparison, no-trace (journal + engine_state bytes),
  wall-clock tolerance, sealed-construction proof
- snapshot regenerated; NOT_YET_MIRRORED debt entries for the two new
  classes (mirrors land with the frontend PR)
- api-contract-v1.md § Replay rewritten for the turn-keyed shape

CORE Workbench UI

React/Vite/TypeScript frontend for CORE Workbench — a local operator UI for inspecting engine state, proposals, evals, and audit trails.

Local development

# Terminal 1 — start the API (W-026)
uv run core workbench api

# Terminal 2 — start the frontend
cd workbench-ui
pnpm install
pnpm dev         # http://127.0.0.1:5173

Custom API URL

VITE_WORKBENCH_API_URL=http://127.0.0.1:9000 pnpm dev

Design system baseline

pnpm preview   # Serves dist/ on http://127.0.0.1:4173
# Navigate to /preview for the Branch 1 design-system baseline

Tests

pnpm test                # Vitest unit + component tests
pnpm test:enum-coverage  # Badge enum coverage (requires uv)

Schema drift detection

The TypeScript types in src/types/api.ts mirror workbench/schemas.py. To check for drift after Python schema changes:

# From repo root
uv run python scripts/dump-api-schemas.py
# Then run: pnpm test (api.test.ts catches field-level drift)

Architecture

  • src/app/ — Shell, TopBar, LeftNav, StatusFooter, ApiErrorBoundary
  • src/api/ — apiFetch client, TanStack Query hooks
  • src/types/ — TypeScript mirrors of Python schemas
  • src/routes/ — Route placeholder components
  • src/design/ — Branch 1 design-system substrate (DO NOT MODIFY except EmptyState and CommandPalette)

ADR cross-references

  • ADR-0160 — Workbench v1 architecture
  • ADR-0162 — Design substrate (Branch 1)
  • ADR-0156, ADR-0157, ADR-0158 — Engine-state checkpoint and reboot audit trail
