# Phase 18 Plan 01: Web Dashboard Foundation Summary

**chi v5 router with go:embed static assets (htmx, CSS), html/template layout, overview dashboard, and Basic/Bearer auth middleware**

## Performance

- **Duration:** 3 min
- **Started:** 2026-04-06T14:59:54Z
- **Completed:** 2026-04-06T15:02:56Z
- **Tasks:** 2
- **Files modified:** 9

## Accomplishments
- chi v5.2.5 HTTP router with middleware stack (RealIP, Logger, Recoverer)
- Vendored htmx v2.0.4, embedded via go:embed alongside CSS and HTML templates
- Overview page with 4 stat cards (Total Keys, Providers, Recon Sources, Last Scan) and recent findings table
- Auth middleware supporting Basic and Bearer token with constant-time comparison, no-op when unconfigured
- 7 tests covering overview rendering, static serving, auth enforcement, and passthrough

## Task Commits

Each task was committed atomically:

1. **Task 1: chi v5 dependency + go:embed static assets + layout template** - `dd2c8c5` (feat)
2. **Task 2 RED: failing tests for server/auth/overview** - `3541c82` (test)
3. **Task 2 GREEN: implement server, auth, handlers** - `268a769` (feat)

## Files Created/Modified
- `pkg/web/server.go` - chi router setup, NewServer constructor, ListenAndServe
- `pkg/web/auth.go` - Basic auth and bearer token middleware with constant-time compare
- `pkg/web/handlers.go` - Overview handler with OverviewData struct, nil-safe DB/provider access
- `pkg/web/embed.go` - go:embed directives for static/ and templates/
- `pkg/web/static/htmx.min.js` - Vendored htmx v2.0.4 (50KB)
- `pkg/web/static/style.css` - Custom overrides for stat cards, findings table, nav
- `pkg/web/templates/layout.html` - Base layout with nav bar, Tailwind CDN, htmx script
- `pkg/web/templates/overview.html` - Dashboard with stat cards grid and findings table
- `pkg/web/server_test.go` - 7 integration tests for server, auth, overview
- `go.mod` / `go.sum` - Added chi v5.2.5

## Decisions Made
- Used html/template (not templ) per CONTEXT.md deferred decision for v1
- Tailwind via CDN rather than standalone build step for v1 simplicity
- Nil-safe handlers allow server to start with zero config (no DB required)
- Auth uses crypto/subtle.ConstantTimeCompare to prevent timing attacks

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None

## User Setup Required
None - no external service configuration required.

## Known Stubs
None - all data paths are wired to real sources (providers.Registry, recon.Engine, storage.DB) or gracefully show zeroes when dependencies are nil.

## Self-Check: PASSED

All 9 files verified present. All 3 commit hashes verified in git log.

## Next Phase Readiness
- Server skeleton ready for Plans 02-05 to add keys page, providers page, API endpoints, SSE
- Router exposed via Router() for easy route additions
- Template parsing supports adding new .html files to templates/
