+# Phase 13 Plan 01: Package Registry Sources Summary
+
+**Four package registry ReconSources (npm, PyPI, crates.io, RubyGems) searching JS/Python/Rust/Ruby ecosystems for provider keyword matches**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-04-06T09:51:16Z
+- **Completed:** 2026-04-06T09:54:00Z
+- **Tasks:** 2
+- **Files modified:** 8
+
+## Accomplishments
+- NpmSource searches npm registry JSON API with 20-result pagination per keyword
+- PyPISource scrapes pypi.org search HTML reusing extractAnchorHrefs from Replit pattern
+- CratesIOSource queries crates.io JSON API with required custom User-Agent header
+- RubyGemsSource queries rubygems.org search.json with fallback URL construction
+- All four sources credentialless, rate-limited, context-aware with httptest test coverage
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Implement NpmSource and PyPISource** - `4b268d1` (feat)
+2. **Task 2: Implement CratesIOSource and RubyGemsSource** - `9907e24` (feat)
+
+## Files Created/Modified
+- `pkg/recon/sources/npm.go` - NpmSource searching npm registry JSON API
+- `pkg/recon/sources/npm_test.go` - httptest tests for NpmSource (4 tests)
+- `pkg/recon/sources/pypi.go` - PyPISource scraping pypi.org search HTML
+- `pkg/recon/sources/pypi_test.go` - httptest tests for PyPISource (4 tests)
+- `pkg/recon/sources/cratesio.go` - CratesIOSource with custom User-Agent
+- `pkg/recon/sources/cratesio_test.go` - httptest tests verifying User-Agent header (4 tests)
+- `pkg/recon/sources/rubygems.go` - RubyGemsSource searching rubygems.org JSON API
+- `pkg/recon/sources/rubygems_test.go` - httptest tests for RubyGemsSource (4 tests)
+
+## Decisions Made
+- PyPI uses HTML scraping with extractAnchorHrefs (reusing Replit pattern) since PyPI has no public search JSON API
+- CratesIO sets custom User-Agent header per crates.io API policy requirements
+- All sources use bare keyword queries via BuildQueries default path
+
+## 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 sources fully wired with real API endpoints and functional Sweep implementations.
+
+## Next Phase Readiness
+- Four package registry sources ready for RegisterAll wiring
+- Pattern established for remaining registry sources (Maven, NuGet, GoProxy)
