+# Phase 10 Plan 03: GitLabSource Summary
+
+GitLabSource is a thin recon.ReconSource that queries GitLab's `/api/v4/search?scope=blobs` endpoint with a PRIVATE-TOKEN header, iterating one search call per provider keyword from the shared BuildQueries helper and emitting a Finding per returned blob with Source pointing at a constructed `projects/<id>/-/blob/<ref>/<path>` URL.
+
+## What Was Built
+
+`pkg/recon/sources/gitlab.go` contains:
+
+- `GitLabSource` struct exposing Token, BaseURL, Registry, Limiters (lazy Client)
+- ReconSource interface methods: `Name()="gitlab"`, `RateLimit()=rate.Every(30ms)`, `Burst()=5`, `RespectsRobots()=false`, `Enabled()` (token non-empty), `Sweep()`
+- `glBlob` response DTO matching GitLab's documented blob search schema
+- `gitlabKeywordIndex()` local helper (prefixed to avoid colliding with peer plan helpers during parallel wave execution)
+- Compile-time `var _ recon.ReconSource = (*GitLabSource)(nil)` assertion
+
+`pkg/recon/sources/gitlab_test.go` covers all behaviors the plan called out:
+
+| Test | Verifies |
+| --- | --- |
+| `TestGitLabSource_EnabledFalseWhenTokenEmpty` | Enabled gating + Name/RespectsRobots accessors |
+| `TestGitLabSource_EmptyToken_NoCallsNoError` | No HTTP request issued when Token=="" |
+| `TestGitLabSource_Sweep_EmitsFindings` | PRIVATE-TOKEN header, `scope=blobs`, two queries × two blobs = 4 Findings, Source URLs contain project_id/ref/path |
+| `TestGitLabSource_Unauthorized` | 401 propagates as `errors.Is(err, ErrUnauthorized)` |
+| `TestGitLabSource_CtxCancellation` | Sweep returns promptly on ctx timeout against a hanging server |
+| `TestGitLabSource_InterfaceAssertion` | Static recon.ReconSource conformance |
+
+## Verification
+
+```
+go build ./...                                       # clean
+go test ./pkg/recon/sources/ -run TestGitLab -v      # 6/6 PASS
+go test ./pkg/recon/sources/                         # full package PASS (3.164s)
+```
+
+## Deviations from Plan
+
+None for must-have behavior. Two minor adjustments:
+
+1. `keywordIndex` helper renamed to `gitlabKeywordIndex` because `pkg/recon/sources/github.go` (Plan 10-02, wave-2 sibling) introduces an identically-named package-level symbol. Prefixing prevents a redeclared-identifier build failure when the parallel wave merges.
+2. Provider name lookup simplified to direct `map[string]string` access on the bare keyword because `formatQuery("gitlab", k)` returns the keyword verbatim (no wrapping syntax), avoiding a second `extractKeyword`-style helper.
+
+## Deferred Issues
+
+None.
+
+## Known Stubs
+
+None.
+
+## Self-Check: PASSED
