+# Phase 16 Plan 02: APKMirror, crt.sh, SecurityTrails Sources Summary
+
+Mobile app metadata scanning via APKMirror, CT log subdomain discovery with config endpoint probing via crt.sh, and DNS intelligence subdomain enumeration with endpoint probing via SecurityTrails API.

+## Completed Tasks
+
+| Task | Name | Commit | Key Files |
+|------|------|--------|-----------|
+| 1 | APKMirror and crt.sh sources | 09a8d4c | apkmirror.go, crtsh.go + tests |
+| 2 | SecurityTrails source | a195ef3 | securitytrails.go + test, register.go, cmd/recon.go |
+
+## Implementation Details
+
+### APKMirrorSource (credentialless)
+- Searches APK release pages for keyword matches using BuildQueries
+- Scans HTML response for ciLogKeyPattern matches in descriptions/changelogs
+- Rate limited: 1 request per 5 seconds, burst 2. Respects robots.txt.
+
+### CrtShSource (credentialless)
+- Queries crt.sh JSON API for certificate transparency log entries matching `%.{domain}`
+- Deduplicates subdomains (strips wildcards), limits to 20
+- Probes each subdomain's /.env, /api/config, /actuator/env with 5s timeout client
+- ProbeBaseURL field enables httptest-based testing
+
+### SecurityTrailsSource (credential-gated)
+- Phase 1: Enumerates subdomains via SecurityTrails API with APIKEY header
+- Phase 2: Probes same three config endpoints as CrtSh (shared configProbeEndpoints)
+- Phase 3: Fetches domain DNS history and checks full JSON for key patterns in TXT records
+- Disabled when SECURITYTRAILS_API_KEY is empty
+
+### RegisterAll
+- Extended from 67 to 70 sources (added APKMirror, crt.sh, SecurityTrails)
+- cmd/recon.go wires SecurityTrailsAPIKey from env/viper
+
+## Deviations from Plan
+
+None -- plan executed exactly as written.
+
+## Known Stubs
+
+None -- all sources fully implemented with real API integration patterns.
+
+## Verification
