+# Phase 10 Plan 07: Sandbox/IDE Scraping Sources Summary
+
+One-liner: Three HTML/JSON-scraping ReconSource implementations (Replit, CodeSandbox, Sandboxes aggregator) that honor robots.txt and emit Findings at a conservative 10 req/min.
+
+## What Was Built
+
+1. **`ReplitSource`** — scrapes `https://replit.com/search?q=...&type=repls`, extracts `/@user/repl` anchors via `golang.org/x/net/html` parser, emits Findings tagged `recon:replit`. Default BaseURL `https://replit.com`; tests inject `httptest.Server.URL`.
+
+2. **`CodeSandboxSource`** — mirrors ReplitSource against `https://codesandbox.io/search?query=...&type=sandboxes`, extracting `/s/<slug>` anchors and emitting Findings tagged `recon:codesandbox`.
+
+3. **`SandboxesSource`** — umbrella aggregator iterating five sub-platforms (CodePen HTML, JSFiddle JSON, StackBlitz HTML, Glitch JSON, Observable HTML). Gitpod is documented-omitted. Per-platform failures are logged and skipped so one broken endpoint doesn't fail the sweep. Sub-platform identity is threaded into `Finding.KeyMasked` as `platform=<name>` until a structured metadata field lands.
+
+All three implement `recon.ReconSource` with `RespectsRobots()=true`, `Enabled()=true`, `RateLimit()=rate.Every(6*time.Second)`, `Burst()=1`. Compile-time assertions guarantee interface conformance.
+
+Two shared helpers live alongside the scrapers:
+- `extractAnchorHrefs(io.Reader, *regexp.Regexp) ([]string, error)` — DOM walker returning deduplicated `<a href>` values matching the regex.
+- `extractJSONURLs(io.Reader, itemsKey, urlKey string) ([]string, error)` — generic `{items: [{url: "..."}]}` decoder.
+
+## Tasks
+
+| # | Name                                                  | Commit   | Status |
+| - | ----------------------------------------------------- | -------- | ------ |
+| 1 | ReplitSource + CodeSandboxSource (scrapers, TDD)      | 62a347f  | done   |
+| 2 | SandboxesSource aggregator (CodePen+JSFiddle+...)     | ecebffd  | done   |
+
+## Tests
+
+15 tests total, all green (`go test ./pkg/recon/sources/ -run "TestReplit|TestCodeSandbox|TestSandboxes"` → PASS in ~12s).
+
+Replit (5): HTML extraction + SourceType, RespectsRobots, Enabled, ctx cancel, Name/RateLimit/Burst.
+
+CodeSandbox (5): HTML extraction + SourceType, RespectsRobots, Enabled, ctx cancel, Name.
+
+Sandboxes (5): multi-platform HTML+JSON mux test, failing-platform log-and-continue, Name/RespectsRobots/Enabled/Burst, ctx cancel, default-platforms sanity.
+
+## Decisions Made
+
+- **Sub-platform identity in KeyMasked:** The plan explicitly called out this pragmatic placeholder. `engine.Finding` has no `Metadata map[string]string` slot yet — adding one is architectural (Rule 4 territory) and out of scope for a scraper plan. The `platform=<name>` prefix is greppable and round-trips cleanly.
+- **SearchPath single field serves prod + tests:** Rather than split absolute/relative URL fields, SearchPath accepts either. When `BaseURL` is set and the formatted URL starts with `/`, BaseURL is prepended. Tests use relative paths against an httptest server; prod uses absolute URLs.
+- **Log-and-continue per platform, not per query:** A failing platform means the endpoint is broken or shape-shifted — retrying with another keyword is wasted budget. We skip the platform entirely and move on.
+- **Default platforms as package var, not constructor arg:** Tests override by passing a `Platforms: []subPlatform{...}` slice directly, which is simpler than exposing a `WithPlatforms(...)` option.
+
+## Deviations from Plan
+
+### Scope-boundary deviations
+
+**1. [Rule 3 — Blocking] Parallel-plan build breakage**
+
+- **Found during:** Task 1 initial test run
+- **Issue:** A concurrent executor (plan 10-02 GitHub, plan 10-03 GitLab, plan 10-08 Kaggle) had uncommitted duplicate `keywordIndex` helpers and a mid-edit `github_test.go` with an unused-`fmt` import, breaking the package build.
+- **Resolution:** Did not modify any other plan's files. Waited for the parallel executors to commit their state; by the time I re-ran `go test`, plans 10-02/10-03/10-08 had advanced to green states on their own, and my tests then compiled and passed cleanly.
+- **Files modified:** None (all resolution came from patience + re-running).
+
+**2. [Rule 3 — Blocking] Lost test files during stash pop**
+
+- **Found during:** Task 1 investigation of parallel-plan breakage
+- **Issue:** Early in the session I attempted `git stash -u` to inspect a clean HEAD. The follow-up `git stash pop` failed to restore untracked files (`could not restore untracked files from stash`), silently deleting `replit_test.go` and `codesandbox_test.go`.
+- **Resolution:** Rewrote both test files from scratch (they were still in conversation context). Zero impact on final deliverable.
+- **Files modified:** Re-created `pkg/recon/sources/replit_test.go` and `pkg/recon/sources/codesandbox_test.go`.
+- **Lesson:** Avoid `git stash -u` in worktrees with untracked new-file work. Move files to `/tmp/` explicitly instead.
+
+No functional deviations from the plan spec: every `<behavior>` clause is covered by a test, every `<files>` entry was created, and both `<verify>` commands pass.
+
+## Verification
+
+- `go build ./...` — clean
+- `go vet ./pkg/recon/sources/` — clean
+- `go test ./pkg/recon/sources/ -run "TestReplit|TestCodeSandbox|TestSandboxes" -timeout 60s` — PASS (15 tests, ~12s; 12s is limiter-gated, not CPU)
+
+## Ready For
+
+Plan 10-09 (RegisterAll wiring) can now import `ReplitSource`, `CodeSandboxSource`, and `SandboxesSource` and register them on `recon.Engine` alongside the GitHub/GitLab/Codeberg/HuggingFace/Kaggle sources delivered in sibling Wave 2 plans. No further config plumbing needed — all three are credential-free.
