 # Silo Frontend Specification
 
-Current as of 2026-02-06. Tracks the React + Vite + TypeScript frontend migration (epic #6).
+Current as of 2026-02-08. Documents the React + Vite + TypeScript frontend (migration from Go templates is complete).
 
 ## Overview
 
-The Silo web UI is being migrated from server-rendered Go templates with vanilla JavaScript (~7,000 lines across 7 templates) to a React single-page application. The Go API server remains unchanged — it serves JSON at `/api/*` and the React app consumes it.

-The final phase completes the migration:
+Completed in commit `50923cf`. All Go templates deleted, `web.go` handler removed, SPA serves at `/` via `NotFound` handler with `index.html` fallback. `build/package/Dockerfile` added.
 
-**Remove Go templates**: Delete `internal/api/templates/` (7 HTML files), remove template loading code, remove web handler route group and CSRF middleware for web routes, remove `HandleIndex`, `HandleProjects`, `HandleSchemas`, `HandleSettings` handlers.
-
-**SPA serving**: Serve `web/dist/` at `/` with SPA fallback (non-API routes return `index.html`). Either `go:embed` for single-binary deployment or filesystem serving. `/api/*` routes must take precedence. Cache headers for Vite's hashed assets.
-
-**Docker**: Update `build/package/Dockerfile` to multi-stage — Stage 1: Node (`npm ci && npm run build`), Stage 2: Go build with `web/dist/`, Final: minimal Alpine image with single binary.
-
-**Makefile**: Existing `web-install`, `web-dev`, `web-build` targets need verification. `make build` should include the web build step. `make clean` should include `web/dist/`.
-
-**Acceptance criteria**: Single Docker image serves both API and React frontend. `make build` produces working binary. No Go template code remains. All pages accessible at React Router paths.
+### Remaining Work
 
 ### Issue #5: Component Audit UI (future)
 
-After migration completes, the Audit page will be expanded with completeness scoring, inline editing, tier filtering, and category breakdowns. This will be built natively in React using the patterns established in the migration.
