Web UI: Added browser-based management for all three remaining engines
(SSH CA, Transit, User E2E). Includes gRPC client wiring, handler files,
7 HTML templates, dashboard mount forms, and conditional navigation links.
Fixed REST API routes to match design specs (SSH CA cert singular paths,
Transit PATCH for update-key-config).
Security audit: Conducted full-system audit covering crypto core, all
engine implementations, API servers, policy engine, auth, deployment,
and documentation. Identified 42 new findings (#39-#80) across all
severity levels.
Remediation of all 8 High findings:
- #68: Replaced 14 JSON-injection-vulnerable error responses with safe
json.Encoder via writeJSONError helper
- #48: Added two-layer path traversal defense (barrier validatePath
rejects ".." segments; engine ValidateName enforces safe name pattern)
- #39: Extended RLock through entire crypto operations in barrier
Get/Put/Delete/List to eliminate TOCTOU race with Seal
- #40: Unified ReWrapKeys and seal_config UPDATE into single SQLite
transaction to prevent irrecoverable data loss on crash during MEK
rotation
- #49: Added resolveTTL to CA engine enforcing issuer MaxTTL ceiling
on handleIssue and handleSignCSR
- #61: Store raw ECDH private key bytes in userState for effective
zeroization on Seal
- #62: Fixed user engine policy resource path from mountPath to
mountName() so policy rules match correctly
- #69: Added newPolicyChecker helper and passed service-level policy
evaluation to all 25 typed REST handler engine.Request structs

- Add PUT /v1/policy/rule endpoint for updating policy rules; expose
full policy CRUD through the web UI with a dedicated policy page
- Add certificate revoke, delete, and get-cert to CA engine and wire
REST + gRPC routes; fix missing interceptor registrations
- Update ARCHITECTURE.md to reflect v2 gRPC as the active implementation,
document ACME endpoints, correct CA permission levels, and add policy/cert
management route tables
- Add POLICY.md documenting the priority-based ACL engine design
- Add web/templates/policy.html for policy management UI
