# Phase 5: Verification Engine Verification Report

**Phase Goal:** Users can opt into active key verification with a consent prompt, legal documentation, and per-provider API calls that confirm whether a found key is live and return metadata about the key's access level.

**Verified:** 2026-04-05
**Status:** passed
**Re-verification:** No — initial verification

## Goal Achievement

### Observable Truths (from ROADMAP Success Criteria)

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | `keyhunter scan --verify` triggers one-time consent prompt; must type "yes" to proceed | VERIFIED | `pkg/verify/consent.go:30` `EnsureConsent`; prompt text contains "legal implications", "keyhunter legal", "Type 'yes' to proceed"; wired in `cmd/scan.go` before `VerifyAll`; consent persisted via `db.SetSetting(ConsentSettingKey, ConsentGranted)`; tests `TestEnsureConsent_*` pass |
| 2 | Provider YAML verify endpoint/method/headers/success/failure codes drive verification — no hardcoded logic | VERIFIED | `pkg/verify/verifier.go` reads `spec.URL`, `spec.Method`, `spec.Headers`, `spec.Body`, `spec.EffectiveSuccessCodes()`, `spec.EffectiveFailureCodes()`, `spec.EffectiveRateLimitCodes()`; grep for provider names in verifier.go finds only a generic comment; `TestTier1VerifySpecs_Complete` asserts all 12 Tier-1 providers have URL+SuccessCodes |
| 3 | `--verify` extracts and displays org/rate-limit/permissions metadata when provider returns them | VERIFIED | `gjson.GetBytes` extraction in `pkg/verify/verifier.go`; 9 Tier-1 YAMLs carry `metadata_paths`; `Finding.VerifyMetadata` populated in `cmd/scan.go:145`; `pkg/output/table.go` `verifySymbol` + metadata `↳` line renders map; `TestVerify_MetadataExtraction`, `TestPrintFindings_Metadata_Rendered` pass |
| 4 | `--verify-timeout=30s` changes per-key timeout from default 10s | VERIFIED | `scan --help` shows `--verify-timeout duration` (default 10s); `NewHTTPVerifier(flagVerifyTimeout)` wired in `cmd/scan.go`; `DefaultTimeout = 10*time.Second` in verifier.go; `TestVerify_Timeout` exercises per-call timeout |
| 5 | `LEGAL.md` ships with the binary documenting legal implications of `--verify` | VERIFIED | `LEGAL.md` (109 lines) at repo root; identical `pkg/legal/LEGAL.md` embedded via `//go:embed LEGAL.md`; `cmd/legal.go` `legalCmd` registered; `go run . legal` prints content; contains "CFAA", "Computer Misuse", "Responsible Use", "Disclaimer" |

**Score:** 5/5 truths verified

### Required Artifacts

| Artifact | Status | Details |
|----------|--------|---------|
| `pkg/providers/schema.go` | VERIFIED | Extended VerifySpec with SuccessCodes, FailureCodes, RateLimitCodes, MetadataPaths, Body + legacy fields + Effective* accessors + ExtractMetadata |
| `pkg/engine/finding.go` | VERIFIED | Finding has Verified/VerifyStatus/VerifyHTTPCode/VerifyMetadata/VerifyError |
| `pkg/storage/schema.sql` | VERIFIED | findings table has verified, verify_status, verify_http_code, verify_metadata_json columns |
| `pkg/storage/findings.go` | VERIFIED | SaveFinding/ListFindings round-trip verify_* columns; migration helper `migrateFindingsVerifyColumns` present |
| `go.mod` | VERIFIED | `github.com/tidwall/gjson` present |
| `LEGAL.md` + `pkg/legal/LEGAL.md` | VERIFIED | Both exist, 109 lines, identical |
| `pkg/legal/legal.go` | VERIFIED | `//go:embed LEGAL.md` with `Text()` accessor |
| `pkg/verify/consent.go` | VERIFIED | `EnsureConsent(db, in, out)` with settings-backed persistence |
| `pkg/verify/verifier.go` | VERIFIED | HTTPVerifier.Verify + VerifyAll (ants pool), {{KEY}} substitution in URL/headers/body, HTTPS-only, gjson metadata |
| `pkg/verify/result.go` | VERIFIED | Result struct with StatusLive/Dead/RateLimited/Error/Unknown constants |
| `cmd/legal.go` | VERIFIED | legalCmd registered in root.go |
| `cmd/scan.go` | VERIFIED | --verify, --verify-timeout, --verify-workers flags; consent gate; VerifyAll pipeline; results back-assigned to findings; SaveFinding persists verify_* |
| `pkg/output/table.go` | VERIFIED | VERIFY column + verifySymbol + metadata `↳` line |
| 12 Tier-1 provider YAMLs (dual-location) | VERIFIED | All 12 in providers/ and pkg/providers/definitions/ are byte-identical; 12 have success_codes; 11 have {{KEY}} (inflection intentionally empty); 9 have metadata_paths |

### Key Link Verification

| From | To | Via | Status |
|------|----|----|--------|
| pkg/storage/findings.go | findings table | INSERT/SELECT verify_* columns | WIRED |
| pkg/verify/consent.go | storage settings table | GetSetting/SetSetting('verify.consent') | WIRED |
| pkg/legal/legal.go | LEGAL.md | go:embed | WIRED |
| pkg/verify/verifier.go | provider.Verify (VerifySpec) | {{KEY}} substitution + http.Client.Do | WIRED |
| pkg/verify/verifier.go | github.com/tidwall/gjson | metadata extraction | WIRED |
| pkg/verify/verifier.go | github.com/panjf2000/ants/v2 | worker pool | WIRED |
| providers/*.yaml | pkg/providers/definitions/*.yaml | dual-location mirror | WIRED — manual diff confirms 12/12 Tier-1 identical (tool reported false-negative because it cannot expand glob paths) |
| cmd/scan.go | pkg/verify.HTTPVerifier.VerifyAll | batch verification | WIRED |
| cmd/scan.go | pkg/verify.EnsureConsent | gate before verification | WIRED |
| cmd/scan.go | storage.SaveFinding | persists VerifyStatus via struct literal | WIRED — manual inspection confirms `storeFinding := storage.Finding{ ... VerifyStatus: f.VerifyStatus, ... }` at cmd/scan.go:157-170 (tool reported false-negative because pattern "storeFinding.VerifyStatus" looks for field-access syntax, not literal initialization) |

### Data-Flow Trace (Level 4)

| Artifact | Data Variable | Source | Produces Real Data | Status |
|----------|---------------|--------|--------------------|--------|
| cmd/scan.go output | findings[i].VerifyStatus | HTTPVerifier.VerifyAll -> results channel -> back-assigned by (provider+KeyMasked) key | Yes — real HTTP responses classified by YAML-defined codes | FLOWING |
| pkg/output/table.go VERIFY column | f.VerifyStatus / f.VerifyMetadata | Populated in cmd/scan.go from verify.Result | Yes — metadata from gjson extraction on JSON responses | FLOWING |
| consent decision | "verify.consent" setting | db.GetSetting/SetSetting via storage settings table | Yes — persisted across runs (granted sticky, declined re-prompts) | FLOWING |

### Behavioral Spot-Checks

| Behavior | Command | Result | Status |
|----------|---------|--------|--------|
| Build succeeds | `go build ./...` | clean | PASS |
| All phase 5 tests green | `go test ./pkg/verify/... ./pkg/legal/... ./pkg/providers/... ./pkg/storage/... ./pkg/output/... ./cmd/...` | all ok | PASS |
| `--verify-timeout` flag present with 10s default | `go run . scan --help \| grep verify-timeout` | shows "--verify-timeout duration ... (default 10s)" | PASS |
| `--verify-workers` flag present | `go run . scan --help \| grep verify-workers` | shows "--verify-workers int ... (default 10)" | PASS |
| `keyhunter legal` prints LEGAL.md | `go run . legal \| head` | prints "# KeyHunter — Legal Disclaimer for Active Key Verification" | PASS |
| LEGAL.md contains CFAA/Computer Misuse/Disclaimer | `grep -c 'CFAA\|Computer Misuse\|Responsible Use\|Disclaimer' LEGAL.md` | 5 hits | PASS |
| Dual-location Tier-1 YAMLs identical | `diff -q providers/<name>.yaml pkg/providers/definitions/<name>.yaml` for 12 providers | no differences | PASS |
| success_codes coverage | `grep -l 'success_codes:' providers/*.yaml \| wc -l` | 12 | PASS |
| {{KEY}} template coverage | `grep -l '{{KEY}}' providers/*.yaml \| wc -l` | 11 (inflection intentionally empty) | PASS |
| metadata_paths coverage | `grep -l 'metadata_paths:' providers/*.yaml \| wc -l` | 9 | PASS |

### Requirements Coverage

| Requirement | Source Plan(s) | Description | Status | Evidence |
|-------------|----------------|-------------|--------|----------|
| VRFY-01 | 05-02, 05-05 | One-time consent prompt with legal language | SATISFIED | EnsureConsent + prompt text + 6 consent tests + cmd/scan.go wiring |
| VRFY-02 | 05-01, 05-03, 05-04 | YAML-driven verification (no hardcoded per-provider logic) | SATISFIED | HTTPVerifier reads VerifySpec only; 12 Tier-1 YAMLs carry complete specs; TestTier1VerifySpecs_Complete guardrail |
| VRFY-03 | 05-01, 05-03, 05-04 | Metadata extraction (org, tier, permissions) | SATISFIED | MetadataPaths + gjson extraction; 9 Tier-1 YAMLs declare paths; TestVerify_MetadataExtraction |
| VRFY-04 | 05-05 | Metadata displayed in output | SATISFIED | pkg/output/table.go `↳` metadata line + TestPrintFindings_Metadata_Rendered |
| VRFY-05 | 05-03, 05-05 | Configurable per-key timeout (default 10s) | SATISFIED | --verify-timeout flag, DefaultTimeout=10s, NewHTTPVerifier(timeout), TestVerify_Timeout |
| VRFY-06 | 05-02 | LEGAL.md shipping with binary | SATISFIED | go:embed LEGAL.md in pkg/legal/legal.go; keyhunter legal prints it |

No ORPHANED requirements — all 6 IDs claimed by at least one plan and verified.

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| pkg/verify/verifier.go | 214 | comment "// substituteKey replaces both {{KEY}} and the legacy {KEY} placeholder" | Info | False-positive: mentions "legacy" in a doc comment; not a stub |

No blocker or warning anti-patterns found. No TODO/FIXME/placeholder/"not yet implemented" markers in phase 5 code.

### Human Verification Required

None. All success criteria have been verified through file inspection, grep checks, test execution, and CLI spot-checks. A human could optionally smoke-test the end-to-end flow with a real API key, but all automated checks pass.

### Gaps Summary

None. All 5 Success Criteria from ROADMAP are met, all 6 requirements are satisfied, all 13 artifacts exist with substantive implementations, all 10 key links are wired (2 tool false-negatives confirmed wired by manual inspection), all unit tests pass, and the binary builds cleanly. The verification engine is complete and ready for users to opt into.
