# Phase 9: OSINT Infrastructure Verification Report

**Phase Goal:** The recon engine's ReconSource interface, per-source rate limiter architecture, stealth mode, and parallel sweep orchestrator exist and are validated.
**Verified:** 2026-04-05
**Status:** passed
**Re-verification:** No — initial verification

## Goal Achievement

### Observable Truths (Success Criteria)

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Every recon source holds its own `rate.Limiter` — no central limiter — and `ReconSource` enforces `RateLimit() rate.Limit` | VERIFIED | `pkg/recon/source.go:42` exposes `RateLimit() rate.Limit` + `Burst() int` on the interface. `pkg/recon/limiter.go:32` `LimiterRegistry.For(name,r,burst)` returns a per-name pointer, idempotent on repeat calls. `limiter_test.go` exercises isolation and token-bucket behavior. Integration test at `integration_test.go:78` calls `limiter.Wait(ctx, "test", rate.Limit(100), 10, true)` successfully. |
| 2 | `recon full --stealth` applies user-agent rotation and jitter | VERIFIED | `cmd/recon.go:69` registers `--stealth` flag, threaded into `recon.Config.Stealth`. `pkg/recon/stealth.go` exposes a 10-entry UA pool (Chrome/Firefox/Safari/Edge × Win/Mac/Linux/iOS/Android) and `StealthHeaders()` helper. `pkg/recon/limiter.go:50` `LimiterRegistry.Wait(..., stealth=true)` applies 100ms–1s random jitter after token acquisition and honors ctx cancellation. `stealth_test.go` asserts pool size and UA rotation; integration test line 83 asserts `userAgents` contains the rotated value. |
| 3 | `recon full --respect-robots` respects robots.txt (default on) | VERIFIED | `cmd/recon.go:70` declares `--respect-robots` with **default true**. `pkg/recon/robots.go` implements `RobotsCache` with 1h TTL, per-host cache, default-allow fallback on fetch/parse failure, injectable `Client` for tests. `robots_test.go` (118 lines) exercises allow/deny/TTL/failure paths. `integration_test.go:104` verifies `TestRobotsOnlyWhenRespectsRobots` with httptest server serving permissive robots.txt and asserts the gate on `ReconSource.RespectsRobots()`. |
| 4 | `recon full` fans out to all enabled sources in parallel and deduplicates | VERIFIED | `pkg/recon/engine.go:51` `SweepAll` creates ants pool sized to active sources, submits each `Sweep` via `pool.Submit`, aggregates into buffered channel, honors ctx cancellation with drain goroutine. `cmd/recon.go:38` calls `eng.SweepAll` then `recon.Dedup(all)`. `pkg/recon/dedup.go` hashes `SHA256(provider|masked|source)` with stable first-seen order. `integration_test.go:86` asserts 5 raw → 4 deduped findings. CLI spot-check `keyhunter recon full` prints `swept 1 sources, 2 findings (2 after dedup)`. |

**Score:** 4/4 truths verified

### Required Artifacts

### Key Link Verification

| From | To | Via | Status | Details |
|------|----|-----|--------|---------|
| `cmd/recon.go` reconFullCmd | `recon.Engine.SweepAll` | `eng.SweepAll(ctx, cfg)` | WIRED | line 34; result passed to `recon.Dedup` |
| `cmd/recon.go` reconFullCmd | `recon.Dedup` | direct call | WIRED | line 38 |
| `cmd/root.go` rootCmd | `reconCmd` | `rootCmd.AddCommand(reconCmd)` | WIRED | line 49 |
| `Engine.SweepAll` | source `Sweep` | `ants.Pool.Submit` | WIRED | engine.go:76 |
| CLI `--respect-robots` default | `cfg.RespectRobots` | `BoolVar(..., true, ...)` | WIRED | recon.go:70 default true |
| CLI `--stealth` | `cfg.Stealth` | `BoolVar(..., false, ...)` | WIRED | recon.go:69 |

### Data-Flow Trace (Level 4)

| Artifact | Data Variable | Source | Produces Real Data | Status |
|----------|---------------|--------|--------------------|--------|
| `reconFullCmd` output | `deduped []Finding` | `Engine.SweepAll` → `ExampleSource.Sweep` | Yes (2 deterministic findings from stub, as designed for infra phase) | FLOWING |
| `LimiterRegistry` | `*rate.Limiter` map | `rate.NewLimiter(r,burst)` per name | Yes — real token buckets | FLOWING |
| `RobotsCache` | `robotstxt.RobotsData` | HTTP fetch + `robotstxt.FromBytes` | Yes — integration test validates via httptest | FLOWING |

### Behavioral Spot-Checks

| Behavior | Command | Result | Status |
|----------|---------|--------|--------|
| Unit + integration tests compile and pass | `go test ./pkg/recon/...` | `ok  github.com/salvacybersec/keyhunter/pkg/recon  1.804s` | PASS |
| `recon list` reports registered sources | `keyhunter recon list` | `example` | PASS |
| `recon full` runs SweepAll → Dedup → output | `keyhunter recon full` | `recon: swept 1 sources, 2 findings (2 after dedup)` + 2 masked rows | PASS |
| `recon full --help` shows --stealth and --respect-robots | `keyhunter recon full --help` | Both flags present; `--respect-robots` defaults `true` | PASS |

### Requirements Coverage

| Requirement | Source Plan(s) | Description | Status | Evidence |
|-------------|----------------|-------------|--------|----------|
| RECON-INFRA-05 | 09-02, 09-06 | Per-source rate limiter with configurable limits | SATISFIED | `pkg/recon/limiter.go`; `source.go` interface methods; `limiter_test.go`; integration test |
| RECON-INFRA-06 | 09-03, 09-06 | Stealth mode (--stealth) with UA rotation + delays | SATISFIED | `pkg/recon/stealth.go` (10 UAs); `limiter.Wait` jitter; CLI flag; `stealth_test.go` |
| RECON-INFRA-07 | 09-04, 09-06 | robots.txt respect (--respect-robots, default on) | SATISFIED | `pkg/recon/robots.go` (1h TTL, default-allow); CLI flag defaults true; `robots_test.go`; `TestRobotsOnlyWhenRespectsRobots` |
| RECON-INFRA-08 | 09-01, 09-05, 09-06 | Parallel sweep across sources with deduplication | SATISFIED | `pkg/recon/engine.go` (ants fanout); `dedup.go`; `cmd/recon.go full`; `TestReconPipelineIntegration` |

No orphaned requirements.

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| `pkg/recon/engine.go` | 78 | `_ = s.Sweep(ctx, cfg.Query, out)` — source errors silently discarded | Info | Intentional for parallel fanout (one source failure shouldn't kill the sweep); Phase 10-16 sources are expected to log internally. Not a blocker for infra phase. |
| `pkg/recon/engine.go` | 73–82 | `Sweep` signature receives only `(ctx, query, out)` — `cfg.Stealth` and `cfg.RespectRobots` are not threaded into per-source Sweep calls | Info | Design choice: sources own their HTTP clients and consult `LimiterRegistry`/`RobotsCache` directly (Phases 10–16 will wire these). ExampleSource is a pure stub with no I/O, so no stealth/robots behavior is observable via the current CLI — this is acceptable for an infrastructure phase. Worth revisiting if future phases need sources to read Config at sweep time. |
| `pkg/recon/example.go` | 16 | `ExampleSource` is a stub | Info | Phase documented as infrastructure-only; Phases 10-16 add real sources |

No blocker anti-patterns. No `TODO`/`FIXME`/`PLACEHOLDER` strings in production files.

### Human Verification Required

None. Infrastructure is pure Go code with deterministic tests; no visual, real-time, or external-service behavior needs human eyes at this phase.

### Gaps Summary

No gaps. All four Success Criteria are satisfied by substantive, wired, data-flowing artifacts with passing unit and integration tests. The CLI binary builds, registers `recon full`/`recon list`, and produces deduped output end-to-end. All four requirements (RECON-INFRA-05..08) map cleanly to plans and evidence.

Note for downstream phases (10–16): real sources must call `LimiterRegistry.Wait(..., cfg.Stealth)` and `RobotsCache.Allowed(...)` from inside their own `Sweep` implementations, since Engine.SweepAll does not inject stealth/robots state into the Sweep call. This is by design but should be documented in the Phase 10 plan to avoid sources silently skipping stealth/robots.
