@@ -98,6 +99,7 @@ Recent decisions affecting current work:
 - [Phase 05]: Store Finding.VerifyMetadata as JSON TEXT column; legacy DBs migrated in-place via PRAGMA table_info + conditional ALTER TABLE in storage.Open()
 - [Phase 05-verification-engine]: LEGAL.md dual-location mirror (root + pkg/legal/) required because go:embed cannot traverse parents — mirrors Phase 1 providers pattern
 - [Phase 05-verification-engine]: verify.consent setting: granted is sticky across runs; declined is not — users who initially refuse can change mind without manual reset
+- [Phase 05-verification-engine]: Plan 05-03: HTTPVerifier classifies via YAML VerifySpec only; no per-provider branches. VerifyAll uses ants pool with per-finding Result guarantee.
