+# Phase 05 Plan 03: HTTPVerifier Core Summary
+
+Built the YAML-driven HTTPVerifier that classifies a single provider verify endpoint call into live/dead/rate_limited/error/unknown, substitutes `{{KEY}}` into URL/headers/body, extracts JSON metadata via gjson, and scales to many findings through an ants worker pool.
+
+## What Shipped
+
+### `pkg/verify/result.go`
+- `Status*` string constants (`live`, `dead`, `rate_limited`, `error`, `unknown`).
+- `Result` struct carrying `ProviderName`, `KeyMasked`, `Status`, `HTTPCode`, `Metadata`, `RetryAfter`, `ResponseTime`, `Error`.
+
+### `pkg/verify/verifier.go`
+- `HTTPVerifier` with a TLS 1.2+ `http.Client`, per-call `Timeout` (default 10s), and a `NewHTTPVerifier(timeout)` constructor.
+- `Verify(ctx, finding, provider) Result`:
+  - Empty `spec.URL` → `StatusUnknown` (provider skipped).
+  - `http://` URL → `StatusError` with `"verify URL must be HTTPS"`.
+  - Default method is `GET`; respects `spec.Method` when set.
+  - `{{KEY}}` and legacy `{KEY}` substituted in URL, each header value, and body.
+  - Per-call `context.WithTimeout(ctx, v.Timeout)` — ctx cancellation maps to `StatusError` with a timeout/deadline/canceled message.
+  - Classification order: `EffectiveSuccessCodes` → live, `EffectiveFailureCodes` → dead, `EffectiveRateLimitCodes` → rate-limited (with `Retry-After` seconds parsed into `Result.RetryAfter`), else unknown.
+  - Metadata only on live + `application/json`; body capped at 1 MiB via `io.LimitReader`; `gjson.GetBytes` per `MetadataPaths` entry.
+- `VerifyAll(ctx, findings, reg, workers) <-chan Result`:
+  - `workers <= 0` falls back to `DefaultWorkers` (10).
+  - `ants.NewPool(workers)`; each finding submitted as a task that resolves its provider via `reg.Get`, runs `Verify`, and emits exactly one `Result`.
+  - Missing providers → `Result{Status: StatusUnknown, Error: "provider not found in registry"}`.
+  - `ctx.Err() != nil` stops further dispatch; inflight tasks drain, `pool.Release()` + `wg.Wait()` guarantee clean close of the result channel.
+  - Pool-init failure degrades gracefully: emits one `StatusError` Result per finding and closes.
+
+### `pkg/providers/registry.go`
+- `NewRegistryFromProviders([]Provider) *Registry` — lightweight constructor that skips YAML loading and builds the Aho-Corasick automaton from the caller-supplied providers. Enables unit tests in `pkg/verify` (and future packages) to work with synthetic providers without touching embedded YAML.
+
+## Tests
+
+13 new tests — all green under `-race`.
+
+**Single-key (`TestVerify_*`):**
+- `Live_200`, `Dead_401`, `RateLimited_429_WithRetryAfter`
+- `MetadataExtraction` (nested path `organization.name` + top-level `tier`)
+- `KeySubstitution_InHeader`, `KeySubstitution_InBody`, `KeySubstitution_InURL`
+- `MissingURL_Unknown`, `HTTPRejected`, `Timeout` (50ms timeout vs 300ms server)
+
+**Worker pool (`TestVerifyAll_*`):**
+- `MultipleFindings` — 5 findings, 3 workers, all live + hit counter.
+- `MissingProvider` — unknown provider yields StatusUnknown and single-result-then-close.
+- `ContextCancellation` — 100 findings behind a 100ms server, cancel after 50ms, asserts channel closes within 3s with strictly fewer than 100 results.
+
+```
+go test ./pkg/verify/... -race -count=1
+ok  	github.com/salvacybersec/keyhunter/pkg/verify	1.557s
+go build ./...  # clean
+```
+
+YAML-driven check:
+
+```
+grep -i 'openai\|anthropic\|groq' pkg/verify/verifier.go
+# no matches
+```
+
+## Requirements Satisfied
+
+- **VRFY-02** — Single `HTTPVerifier` drives every provider via `VerifySpec`; no per-provider branches in the verifier.
+- **VRFY-03** — JSON metadata extracted via `gjson` paths from `VerifySpec.MetadataPaths` on live responses.
+- **VRFY-05** — Per-call timeout honored (`Timeout` field, default 10s); configurable through `NewHTTPVerifier`.
+
+## Deviations from Plan
+
+**[Rule 3 — Blocking] Added `providers.NewRegistryFromProviders` test helper.**
+- **Found during:** Task 2 — verifier_test.go needed a Registry containing only a synthetic `testprov` provider, but `providers.Registry` only exposed `NewRegistry()` (loads all embedded YAML) and had unexported fields.
+- **Fix:** Added a small exported constructor that accepts a `[]Provider`, builds the Aho-Corasick automaton inline, and returns a ready Registry. Keeps the package's invariants intact.
+- **Files modified:** `pkg/providers/registry.go`
+- **Commit:** `45ee2f8`
+
+**[Rule 3 — Blocking, transient] Cross-plan build break from parallel Plan 05-02 RED commit.**
+- **Found during:** Task 1 GREEN verification run.
+- **Issue:** Plan 05-02 (consent prompt) runs in the same wave and had committed `consent_test.go` with a failing RED step referencing `EnsureConsent`, `ConsentSettingKey`, `ConsentGranted`, and `ConsentDeclined` — making the whole `pkg/verify` package non-buildable and blocking my tests from compiling.
+- **Fix:** During investigation, the parallel 05-02 agent's GREEN commit (`d4c1403 feat(05-02): implement EnsureConsent`) landed on `master`, so no stub file from this plan was needed. Verified both test suites (6 consent tests + 13 verify tests) pass together.
+- **Files modified:** none (05-02's commit resolved it)
+- **Note:** This kind of race is expected when wave-1 plans share a working directory instead of isolated worktrees. Worth flagging for the orchestrator.
+
+No architectural deviations. No auth gates. No deferred issues.
+
+## Key Decisions
+
+1. **Substitution helper is string-level, not template-engine.** `{{KEY}}` (and legacy `{KEY}`) are `strings.ReplaceAll` targets. No `text/template`, no escaping — raw byte-for-byte replacement. This matches what every existing provider YAML expects and avoids the footgun of accidental template directives in header values.
+2. **Metadata is gated on StatusLive.** There is no good reason to parse a 401 body for "org name" — the response is typically an error blob with unrelated fields. Gating on `StatusLive` keeps `Result.Metadata` meaningful.
+3. **1 MiB body cap for metadata extraction.** Defensive against hostile/runaway JSON responses. Legitimate verify endpoints return a few KB at most; 1 MiB is 1000× headroom.
+4. **One Result per Finding, always.** `VerifyAll` emits a result for every input finding — success, failure, missing provider, or pool-init error. Callers can count findings vs results and never have to reconcile gaps.
+5. **`Result.ProviderName` and `KeyMasked` populated even on error paths.** Downstream consumers can display the masked key + provider next to the failure reason without a second lookup.

+
+## Known Stubs
+
+None. All values flowing through `Result` are derived from live HTTP responses or documented error paths; no hardcoded placeholder data.
+
+## Next Up
+
+- Plan 05-04 (verify spec completeness for Tier 1 providers) — already in progress in a sibling worktree.
+- Plan 05-05 will wire `HTTPVerifier.VerifyAll` into the scan pipeline behind `--verify`, reusing the `Result` channel shape defined here.
