# Phase 18 Plan 02: REST API + SSE Hub Summary

**Complete REST API at /api/v1/* with 14 endpoints (keys, providers, scan, recon, dorks, config) plus SSE hub for live event streaming**

## Performance

- **Duration:** 7 min
- **Started:** 2026-04-06T14:59:58Z
- **Completed:** 2026-04-06T15:06:51Z
- **Tasks:** 2
- **Files modified:** 7

## Accomplishments
- Full REST API with 14 endpoints covering stats, keys CRUD, providers, scan/recon triggers, dorks, and config
- SSE hub with subscribe/unsubscribe/broadcast lifecycle and non-blocking buffered channels
- 23 passing tests (16 API + 7 SSE) covering happy paths and error cases

## Task Commits

Each task was committed atomically:

1. **Task 1: REST API handlers for /api/v1/*** - `76601b1` (feat)
2. **Task 2: SSE hub for live scan/recon progress** - `d557c73` (feat)

## Files Created/Modified
- `pkg/web/server.go` - Server struct with ServerConfig dependency injection
- `pkg/web/api.go` - All 14 REST API handlers with JSON wrapper types
- `pkg/web/sse.go` - SSEHub with Subscribe/Unsubscribe/Broadcast + HTTP handlers
- `pkg/web/api_test.go` - 16 tests for all API endpoints
- `pkg/web/sse_test.go` - 7 tests for SSE hub lifecycle and HTTP streaming
- `pkg/storage/schema.sql` - Resolved merge conflict (HEAD version kept)
- `go.mod` / `go.sum` - Added chi v5.2.5

## Decisions Made
- JSON wrapper structs (apiKey, apiProvider, apiDork) with explicit JSON tags since domain structs only have yaml tags -- ensures consistent camelCase JSON API
- API never exposes raw key values -- KeyValue always empty string in JSON responses for security
- Single SSEHub shared between scan and recon progress endpoints, events distinguished by Type prefix (scan:*, recon:*)
- DisallowUnknownFields removed from readJSON to avoid overly strict request parsing

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 3 - Blocking] Resolved merge conflict in schema.sql**
- **Found during:** Task 1
- **Issue:** schema.sql had unresolved git merge conflict markers between two versions of scheduled_jobs table
- **Fix:** Kept HEAD version (includes subscribers table + scheduled_jobs with scan_command column) and added missing index
- **Files modified:** pkg/storage/schema.sql
- **Verification:** All tests pass with resolved schema
- **Committed in:** 76601b1

**2. [Rule 1 - Bug] Added JSON wrapper structs for domain types**
- **Found during:** Task 1
- **Issue:** Provider, Dork, and Finding structs only have yaml tags -- json.Marshal would produce PascalCase field names inconsistent with REST API conventions
- **Fix:** Created apiKey, apiProvider, apiDork structs with explicit JSON tags and converter functions
- **Files modified:** pkg/web/api.go
- **Verification:** Tests check exact JSON field names (providerName, name, etc.)
- **Committed in:** 76601b1

---

**Total deviations:** 2 auto-fixed (1 blocking, 1 bug)
**Impact on plan:** Both fixes necessary for correctness. No scope creep.

## Issues Encountered
None beyond the auto-fixed deviations above.

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

## Known Stubs
None - all endpoints are fully wired to their backing registries/database.

## Next Phase Readiness
- REST API and SSE infrastructure ready for Plan 18-03 (HTML pages with htmx consuming these endpoints)
- Server struct ready to be wired into cmd/serve.go
