+<objective>
+Implement `DirSource` — a recursive directory scanner that walks a root path via `filepath.WalkDir`, honors glob exclusion patterns, detects and skips binary files, and uses memory-mapped I/O for large files. This satisfies INPUT-01 (directory/recursive scanning with exclusions) and CORE-07 (mmap large file reading).
+
+Purpose: The most common scan target is a repo directory, not a single file. This plan replaces the "wrap FileSource per path" hack with a purpose-built recursive source that emits deterministically ordered chunks and scales to multi-GB files without blowing out memory.
+Output: `pkg/engine/sources/dir.go`, `dir_test.go`, plus a small `file.go` update to share the mmap read helper.

+<objective>
+Implement `GitSource` — a git-history-aware input adapter that walks every commit across every branch and tag in a local repository, deduplicates blob scans by OID, and emits chunks with commit-SHA-prefixed source identifiers. Satisfies INPUT-02.
+
+Purpose: Leaked keys often exist only in git history — deleted from HEAD but still reachable via old commits. A one-shot HEAD scan misses them. This source walks the full commit graph using `go-git/v5` with blob-level deduplication so a 10k-commit repo with 200k historical files scans in minutes, not hours.
+Output: `pkg/engine/sources/git.go` and `git_test.go`. Wired into CLI in plan 04-05.

+<objective>
+Implement three smaller Source adapters in a single plan since each is <80 lines and they share no state:
+- `StdinSource` reads from an injectable `io.Reader` (defaults to `os.Stdin`) — INPUT-03
+- `URLSource` fetches a remote URL via stdlib `net/http` with timeout, size cap, scheme whitelist, and content-type filter — INPUT-04
+- `ClipboardSource` reads the current clipboard via `github.com/atotto/clipboard` with graceful fallback — INPUT-05
+
+Purpose: These three adapters complete the Phase 4 input surface area. Bundling them into one plan keeps wave-1 parallelism healthy (04-02 + 04-03 + 04-04 run simultaneously) while respecting the ~50% context budget since each adapter is self-contained and small.
+Output: Six files total (three sources + three test files).

+<objective>
+Wire the four new source adapters (DirSource, GitSource, StdinSource, URLSource, ClipboardSource) into `cmd/scan.go` via a new `selectSource` helper that inspects CLI flags and positional args to pick exactly one source. Satisfies INPUT-06 (the "all inputs flow through the same pipeline" integration requirement).
+
+Purpose: Plans 04-02 through 04-04 deliver the Source implementations in isolation. This plan is the single integration point that makes them reachable from the CLI, with argument validation to prevent ambiguous invocations like `keyhunter scan --git --url https://...`.
+Output: Updated `cmd/scan.go` with new flags and dispatching logic, plus a focused test file exercising `selectSource` directly.

+  </behavior>
+  <action>
+
+Edit `cmd/scan.go`. The end state must:
+
+1. Add new package-level flag vars alongside the existing ones:
+
+```go
+var (
+	flagWorkers     int
+	flagVerify      bool
+	flagUnmask      bool
+	flagOutput      string
+	flagExclude     []string
+	flagGit         bool
+	flagURL         string
+	flagClipboard   bool
+	flagSince       string
+	flagMaxFileSize int64
+	flagInsecure    bool
+)
+```
+
+2. Change `scanCmd.Args` so a positional target is optional when `--url` or `--clipboard` is used:
+
+```go
+var scanCmd = &cobra.Command{
+	Use:   "scan [path|stdin|-]",
+	Short: "Scan files, directories, git history, stdin, URLs, or clipboard for leaked API keys",
+	Args:  cobra.MaximumNArgs(1),
+	RunE: func(cmd *cobra.Command, args []string) error {
+		// ... existing config load ...
+
+		src, err := selectSource(args, sourceFlags{
+			Git:       flagGit,
+			URL:       flagURL,
+			Clipboard: flagClipboard,
+			Since:     flagSince,
+			Excludes:  flagExclude,
+		})
+		if err != nil {
+			return err
+		}
+
+		// Replace the old `src := sources.NewFileSource(target)` line with use of the dispatched src.
+		// Keep all downstream code unchanged (engine, storage, output).
+
+		// ... rest of existing RunE body, using src ...
+		_ = src
+		return nil // placeholder — keep existing logic
+	},
+}
+```
+
+3. Add the selectSource helper and its supporting struct, in `cmd/scan.go`:
+
+```go
+// sourceFlags captures the CLI inputs that control source selection.
+// Extracted into a struct so selectSource is straightforward to unit test.
+type sourceFlags struct {
+	Git       bool
+	URL       string
+	Clipboard bool
+	Since     string
+	Excludes  []string
+}
+
+// selectSource inspects positional args and source flags, validates that
+// exactly one source is specified, and returns the appropriate Source.
+func selectSource(args []string, f sourceFlags) (sources.Source, error) {
+	// Count explicit source selectors that take no positional path.
+	explicitCount := 0
+	if f.URL != "" {
+		explicitCount++
+	}
+	if f.Clipboard {
+		explicitCount++
+	}
+	if f.Git {
+		explicitCount++
+	}
+	if explicitCount > 1 {
+		return nil, fmt.Errorf("scan: --git, --url, and --clipboard are mutually exclusive")
+	}
+
+	// Clipboard and URL take no positional argument.
+	if f.Clipboard {
+		if len(args) > 0 {
+			return nil, fmt.Errorf("scan: --clipboard does not accept a positional argument")
+		}
+		return sources.NewClipboardSource(), nil
+	}
+	if f.URL != "" {
+		if len(args) > 0 {
+			return nil, fmt.Errorf("scan: --url does not accept a positional argument")
+		}
+		return sources.NewURLSource(f.URL), nil
+	}
+
+	if len(args) == 0 {
+		return nil, fmt.Errorf("scan: missing target (path, stdin, -, or a source flag)")
+	}
+	target := args[0]
+
+	if target == "stdin" || target == "-" {
+		if f.Git {
+			return nil, fmt.Errorf("scan: --git cannot be combined with stdin")
+		}
+		return sources.NewStdinSource(), nil
+	}
+
+	if f.Git {
+		gs := sources.NewGitSource(target)
+		if f.Since != "" {
+			t, err := time.Parse("2006-01-02", f.Since)
+			if err != nil {
+				return nil, fmt.Errorf("scan: --since must be YYYY-MM-DD: %w", err)
+			}
+			gs.Since = t
+		}
+		return gs, nil
+	}
+
+	info, err := os.Stat(target)
+	if err != nil {
+		return nil, fmt.Errorf("scan: stat %q: %w", target, err)
+	}
+	if info.IsDir() {
+		return sources.NewDirSource(target, f.Excludes...), nil
+	}
+	return sources.NewFileSource(target), nil
+}
+```
+
+4. In the existing `init()`, register the new flags next to the existing ones:
+
+```go
+func init() {
+	scanCmd.Flags().IntVar(&flagWorkers, "workers", 0, "number of worker goroutines (default: CPU*8)")
+	scanCmd.Flags().BoolVar(&flagVerify, "verify", false, "actively verify found keys (opt-in, Phase 5)")
+	scanCmd.Flags().BoolVar(&flagUnmask, "unmask", false, "show full key values (default: masked)")
+	scanCmd.Flags().StringVar(&flagOutput, "output", "table", "output format: table, json")
+	scanCmd.Flags().StringSliceVar(&flagExclude, "exclude", nil, "extra glob patterns to exclude (e.g. *.min.js)")
+
+	// Phase 4 source-selection flags.
+	scanCmd.Flags().BoolVar(&flagGit, "git", false, "treat target as a git repo and scan full history")
+	scanCmd.Flags().StringVar(&flagURL, "url", "", "fetch and scan a remote http(s) URL (no positional arg)")
+	scanCmd.Flags().BoolVar(&flagClipboard, "clipboard", false, "scan current clipboard contents")
+	scanCmd.Flags().StringVar(&flagSince, "since", "", "for --git: only scan commits after YYYY-MM-DD")
+	scanCmd.Flags().Int64Var(&flagMaxFileSize, "max-file-size", 0, "max file size in bytes to scan (0 = unlimited)")
+	scanCmd.Flags().BoolVar(&flagInsecure, "insecure", false, "for --url: skip TLS certificate verification")
+
+	_ = viper.BindPFlag("scan.workers", scanCmd.Flags().Lookup("workers"))
+}
+```
+
+5. Replace the single line `src := sources.NewFileSource(target)` in the existing RunE body with the `selectSource` dispatch. Leave ALL downstream code (engine.Scan, storage.SaveFinding, output switch, exit code logic) untouched. Ensure the `target` variable is only used where relevant (it is no longer the sole driver of source construction).
+
+6. Add the `time` import to `cmd/scan.go`.
+
+Create `cmd/scan_sources_test.go`:
+
+```go
+package cmd

+	"path/filepath"

+	"time"

+# Phase 12 Plan 02: FOFA, Netlas, BinaryEdge Sources Summary
+
+**Three IoT/device scanner recon sources (FOFA, Netlas, BinaryEdge) with httptest-based unit tests covering sweep, auth, and cancellation**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-04-06T09:22:18Z
+- **Completed:** 2026-04-06T09:24:22Z
+- **Tasks:** 2
+- **Files modified:** 6
+
+## Accomplishments
+- FOFASource searches FOFA API with base64-encoded queries and email+key authentication
+- NetlasSource searches Netlas API with X-API-Key header authentication
+- BinaryEdgeSource searches BinaryEdge API with X-Key header authentication
+- All three sources follow established Phase 10 pattern with shared Client, LimiterRegistry, BuildQueries
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Implement FOFASource, NetlasSource, BinaryEdgeSource** - `270bbbf` (feat)
+2. **Task 2: Unit tests for FOFA, Netlas, BinaryEdge sources** - `d6c35f4` (test)

+# Phase 12 Plan 03: Cloud Storage Scanners Summary
+
+**Four credentialless cloud storage recon sources (S3, GCS, Azure Blob, DO Spaces) with provider-keyword bucket enumeration and config-file pattern detection**
+
+## Performance
+
+- **Duration:** 4 min
+- **Started:** 2026-04-06T09:22:08Z
+- **Completed:** 2026-04-06T09:26:11Z
+- **Tasks:** 2
+- **Files modified:** 8
+
+## Accomplishments
+- S3Scanner enumerates public AWS S3 buckets using S3 ListBucketResult XML parsing
+- GCSScanner enumerates public GCS buckets using JSON listing format
+- AzureBlobScanner enumerates public Azure Blob containers using EnumerationResults XML
+- DOSpacesScanner enumerates public DO Spaces across 5 regions using S3-compatible XML
+- Shared bucketNames() generates candidates from provider names + common suffixes
+- Shared isConfigFile() detects .env, .json, .yaml, .toml, .conf and similar patterns
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Implement S3Scanner and GCSScanner** - `47d542b` (feat)
+2. **Task 2: Implement AzureBlobScanner, DOSpacesScanner, and all tests** - `13905eb` (feat)
+
+## Files Created/Modified
+- `pkg/recon/sources/s3scanner.go` - S3 bucket enumeration with XML ListBucketResult parsing
+- `pkg/recon/sources/gcsscanner.go` - GCS bucket enumeration with JSON listing parsing
+- `pkg/recon/sources/azureblob.go` - Azure Blob container enumeration with XML EnumerationResults parsing
+- `pkg/recon/sources/dospaces.go` - DO Spaces enumeration across 5 regions (S3-compatible XML)
+- `pkg/recon/sources/s3scanner_test.go` - httptest tests for S3Scanner

+- `pkg/recon/sources/azureblob_test.go` - httptest tests for AzureBlobScanner
+- `pkg/recon/sources/dospaces_test.go` - httptest tests for DOSpacesScanner
+
+## Decisions Made
+- bucketNames uses provider Name (not Keywords) as base for bucket name generation -- produces more realistic bucket names like "openai-keys" vs "sk-proj--keys"
+- HEAD probe before GET to minimize bandwidth on non-public buckets
+- Azure iterates a fixed list of common container names within each generated account name
+- DO Spaces iterates all 5 supported regions per bucket name
+- Tests omit rate limiters (nil Limiters) to avoid test slowness from the 500ms rate limit across many bucket/region combinations
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+- Azure and DO Spaces tests initially timed out due to rate limiter overhead (9 bucket names x 7 containers = 63 requests at 500ms each). Resolved by omitting rate limiters in tests since rate limiting is tested at the LimiterRegistry level.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Four cloud storage scanners ready for RegisterAll wiring
+- Sources use same pattern as Phase 10/11 sources (BaseURL override, shared Client, LimiterRegistry)

+# Phase 12 Plan 04: RegisterAll Wiring + Integration Test Summary
+
+**Wire all 10 Phase 12 IoT/cloud sources into RegisterAll with env/viper credentials and 28-source integration test**
+
+## Performance
+
+- **Duration:** 14 min
+- **Started:** 2026-04-06T09:28:20Z
+- **Completed:** 2026-04-06T09:42:09Z
+- **Tasks:** 2
+- **Files modified:** 4
+
+## Accomplishments
+- Extended SourcesConfig with 8 credential fields for 6 IoT scanner APIs (Shodan, Censys, ZoomEye, FOFA, Netlas, BinaryEdge)
+- Registered all 10 Phase 12 sources in RegisterAll (6 IoT + 4 cloud storage), bringing total to 28
+- Wired env var + viper config credential lookup in cmd/recon.go for all Phase 12 sources
+- Integration test verifies all 28 sources produce findings through multiplexed httptest server
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Extend SourcesConfig, RegisterAll, and cmd/recon.go** - `8704316` (feat)
+2. **Task 2: Integration test for all 28 registered sources** - `f0f2219` (test)
+
+## Files Created/Modified
+- `pkg/recon/sources/register.go` - Added Phase 12 credential fields + source registrations (28 total)
+- `cmd/recon.go` - Added env/viper credential wiring for 8 IoT scanner fields
+- `pkg/recon/sources/integration_test.go` - Extended with Phase 12 IoT + cloud storage fixtures and assertions
+- `pkg/recon/sources/register_test.go` - Updated expected source count from 18 to 28
+
+## Decisions Made
+- Cloud storage sources (S3, GCS, AzureBlob, DOSpaces) are credentialless and always enabled
+- IoT sources require API keys and report Enabled()==false when credentials are empty
+- Integration test uses format-specific handlers: S3/DOSpaces share S3 XML handler, GCS gets JSON handler, AzureBlob gets EnumerationResults XML handler
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Updated existing register_test.go expected source count**
+- **Found during:** Task 2 (integration test)
+- **Issue:** TestRegisterAll_WiresAllEighteenSources and TestRegisterAll_MissingCredsStillRegistered expected 18 sources, now 28
+- **Fix:** Updated expected count to 28 and added all Phase 12 source names to expected list
+- **Files modified:** pkg/recon/sources/register_test.go
+- **Verification:** All RegisterAll tests pass
+- **Committed in:** f0f2219 (Task 2 commit)
+
+**2. [Rule 3 - Blocking] Merged main branch to get Phase 12 source files**
+- **Found during:** Task 1 (build verification)
+- **Issue:** Worktree branch did not have Phase 12-01/12-02 source files (shodan.go, censys.go, etc.)
+- **Fix:** Merged main branch into worktree (fast-forward)
+- **Verification:** go build ./cmd/... succeeds
+
+---
+
+**Total deviations:** 2 auto-fixed (1 bug, 1 blocking)
+**Impact on plan:** Both fixes necessary for correctness. No scope creep.
+
+## Issues Encountered
+None beyond the deviations listed above.
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- All 28 OSINT sources are wired and discoverable via `keyhunter recon list`
+- Phase 13+ sources can follow the same pattern: add fields to SourcesConfig, register in RegisterAll, wire credentials in cmd/recon.go
+- Integration test template established for validating all sources end-to-end
