📝 WalkthroughWalkthroughThe PR adds a thread-safe credential registry with generation tracking, prompt bindings, connection state, and TTL cleanup. It adds credential authentication for supported HTTP and websocket transports. API requests can refresh credentials after eligible Priority: ➖ Normal Merge Risk: ⚪ Minimal · up to This change adds credential-isolated storage, authenticated reconnects, and secret redaction for API-node credentials, restricted to direct loopback or direct TLS connections by design. The one previously open concern about local reverse proxies appearing as loopback peers is a known, documented deployment limitation (operators must terminate TLS themselves) rather than a defect, and no new material issues were found in this review pass, so the change appears ready to merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@server.py`:
- Around line 174-178: Update the peer validation logic around the loopback
check to avoid enabling credential transport solely because the immediate peer
is loopback. Require an explicit trusted/secure-proxy configuration before
treating loopback connections as direct clients, and otherwise disable
credential transport when end-to-end TLS cannot be established.
