+# Phase 11 Plan 02: Paste Site Sources Summary
+
+**Three paste site ReconSources implementing two-phase search+raw-fetch with keyword matching against provider registry**
+
+## What Was Built
+
+### PastebinSource (`pkg/recon/sources/pastebin.go`)
+- Searches pastebin.com for provider keywords, extracts 8-char paste IDs from HTML
+- Fetches `/raw/{pasteID}` content (256KB cap), matches against provider keyword set
+- Emits findings with SourceType="recon:pastebin" and ProviderName from matched keyword
+- Rate: Every(3s), Burst 1, credential-free, respects robots.txt
+
+### GistPasteSource (`pkg/recon/sources/gistpaste.go`)
+- Scrapes gist.github.com public search (no auth needed, distinct from Phase 10 API-based GistSource)
+- Extracts gist links matching `/<user>/<hex-hash>` pattern, fetches `{gistPath}/raw`
+- Keyword-matches raw content, emits findings with SourceType="recon:gistpaste"
+- Rate: Every(3s), Burst 1, credential-free
+
+### PasteSitesSource (`pkg/recon/sources/pastesites.go`)
+- Multi-platform aggregator following SandboxesSource pattern
+- Covers 4 paste sub-platforms: dpaste.org, paste.ee, rentry.co, hastebin.com
+- Each platform has configurable SearchPath, ResultLinkRegex, and RawPathTemplate
+- Per-platform error isolation: failures logged and skipped without aborting others
+- Findings tagged with `platform=<name>` in KeyMasked field
+
+## Test Coverage
+
+9 tests total across 3 test files:
+- Sweep with httptest fixtures verifying finding extraction and keyword matching
+- Name/rate/burst/robots/enabled metadata assertions
+- Context cancellation handling
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
