Minor Changes

• 46c2a97: Add the n8n agentic-callback ruleset. The engine gains a workflow-JSON adapter that ingests *.workflow.json files and n8n community custom-nodes (package.json#n8n.nodes, INodeType/IWebhookFunctions sources), synthesizing handler models from n8n trigger/webhook nodes. A new n8n rule pack detects unverified-body agent/tool sinks (VAS/BYP on getBodyData(), $json, items[0].json reaching agent-tool calls) while staying silent on mitigated, signature-verified shapes. The hookwarden CLI now scans n8n projects end-to-end (scan surfaces n8n findings and malformed-workflow parse errors).

• 056ba21: Add queue-handler + edge-runtime reachability overlays and the first asymmetric (Ed25519) provider.

  • REACH-01 — queue-handler reachability: a handler that enqueues the raw body via bullmq / SQS / inngest / Kafka and has a verifying consumer of that queue reachable now resolves to manual-review instead of not-verified (the engine can't prove same-payload verification across the queue boundary, so it never claims verified). A queue enqueue with no verifying consumer stays not-verified.
  • REACH-02 — edge-runtime detection: webhook handlers on Cloudflare Workers (export default { fetch }), Vercel Edge (runtime: 'edge'), and Deno (Deno.serve) are now detected (Next.js App Router was already covered), so the HMAC-over-raw-body rules evaluate them instead of missing or mis-flagging. The full rule pack's applies_to now includes cloudflare-workers / vercel-edge / deno.
  • DISCORD-01 — Ed25519 provider: Discord interactions are the first asymmetric provider (signature_scheme: ed25519, verified against the app public key). The rule recognizes verifyKey (discord-interactions-js), nacl.sign.detached.verify (tweetnacl), nacl.signing.VerifyKey(...).verify(...) (PyNaCl), and sodium_crypto_sign_verify_detached (PHP) as verified; a Discord handler with no Ed25519 verification is not-verified. Discord interaction paths are now detected.

  Engine purity preserved; existing HMAC providers untouched.

• 1bd1791: Complete the Standard Webhooks detector with the hand-rolled prong (Clerk CVE-2025-53548) and fix a provider-attribution bug it surfaced.

  • STDWH-01 hand-rolled prong: a handler that re-implements the Standard Webhooks spec by hand — HMAC-SHA256 over the canonical {msg_id}.{timestamp}.{body} string — is now graded three ways. With no comparison reachable it is not-verified (the Clerk CVE-2025-53548 shape, where the signature is computed but never checked); with only an undecidable local compare wrapper (safeCompare() / verifySig()) it is manual-review; with a recognized constant-time compare it defers. Covers JS/TS (Babel), Python (tree-sitter), and PHP (tree-sitter source-walk). Plan 16 shipped only the library-import prong, so hand-rolled re-implementations were previously missed.
  • multi-signature-mishandled: a new rule for the v1,<sig1> v1,<sig2> rotation list — a manual-HMAC handler with no signature-iteration symbol reachable is manual-review (it likely breaks the moment a secret is rotated).
  • Provider-attribution fix: a correctly-verified hand-rolled handler (crypto.createHmac + crypto.timingSafeEqual) was mis-attributed to anthropic-agent-sdk and graded by the wrong provider's rules. Generic stdlib crypto primitives that some catalog entries list as VAS-01 suppression anchors no longer drive provider attribution; the VAS-01 suppression itself is unchanged.

  No whsec_ hardcoded-secret rule is added — the existing Stripe rule already matches it provider-agnostically. Engine purity preserved.

• c10427a: v0.8 launch — webhook integrity, from first line to final audit.

  This is the stable v0.8 cut of the CLI + engine + rules cluster. It rolls up the
  v0.8 milestone surface: the n8n agentic-callback ruleset (detecting unverified
  agent/tool webhook sinks, shipped after the Cisco Talos n8n abuse report), the
  Anthropic Agent SDK tool-callback ruleset, and the compliance_mappings schema
  (SOC 2 + ISO 27001 + EU AI Act Annex III + NIST AI RMF) surfaced in
  hookwarden --version --verbose, with the v1.1 evidence pack carrying the EU AI
  Act Annex III high-risk classification and an embedded offline-verifiable
  signing key.

  The MCP server shipped earlier in the v0.8 cycle and versions independently of
  this fixed cluster, so it is intentionally not part of this changeset.

Patch Changes

• a7424fc: Fix a false-positive critical on correctly-verified GitHub webhook handlers. The
  github-timing-safe-equal predicate (backing github/missing-timing-safe-equal and
  github/timing-unsafe-comparison) returned "verified" on the safe path; because the engine
  builds a finding for any non-null verdict and stamps it with the rule's fixed critical severity
  and "verification missing" message, a textbook-correct hand-rolled handler
  (crypto.createHmac + crypto.timingSafeEqual, exactly per GitHub's docs) surfaced two
  false-positive criticals and failed the build. The safe path now returns null (no finding) —
  the positive signal remains the job of the info-severity github/library-verified rule, matching
  the convention every other provider's critical rules already follow.

  Also makes --fail-on gating state-aware so exit codes match the documented summary legend:
  verified findings never gate (a correctly-verified handler is not a build failure),
  manual-review findings gate only at --fail-on low/info (not the default high), and
  not-verified findings continue to gate by severity.

• ade4609: Cut real-app false positives from provider over-detection / mis-attribution (found scanning dub):

  • Generic HTTP headers no longer drive provider attribution. Postmark's catalog signature_header
    is authorization (its Basic-Auth scheme), but Authorization is read by nearly every
    authenticated route — so OAuth token endpoints, cron jobs, and admin routes were attributed to
    postmark and flagged as unverified postmark webhooks. A generic-header read (Authorization,
    Content-Type, …) is now recorded provider-agnostically; real postmark webhooks are still attributed
    by their specific signals (/postmark/* paths, SDK, POSTMARK_* env), and postmark's rules detect
    Basic-Auth via reachable symbols, not this header.

  • Stripe v2 verify calls recognized. stripe.parseThinEvent(...) (v2 API / thin events) and
    webhooks.constructEventAsync(...) (Edge/Workers async API) are now treated as signature
    verification, so correctly-verified v2 webhooks are no longer flagged
    stripe/missing-signature-verification.

  Combined with the req.text() raw-body fix, false-positive criticals on the dub codebase dropped
  from 20 to 9 (the remaining 9 are genuine unverified webhook routes plus two non-webhook routes that
  merely import the Stripe SDK — a separate over-detection class tracked for follow-up).

• c7f1046: Add Remix support. Remix action route modules under app/routes/** receive a Web Fetch API
  Request — identical to Next.js App Router — but were undetected, so a real Remix webhook scanned to
  0 handlers and silently reported "clean" (a false negative; found scanning documenso, whose Stripe
  webhook is apps/remix/app/routes/api+/stripe.webhook.ts). New remixAdapter detects action
  exports and derives the route from the remix-flat-routes filename (api+/stripe.webhook →
  /api/stripe/webhook); rules apply to remix via the nextjs equivalence in ruleAppliesToFramework
  (no per-rule YAML churn). remix added to the engine Framework union + the rules applies_to enum.
