daemon: enforce peer pubkey binding on the runtime data plane + panic-recover - #424

…-recover Mirrors the handshake trust key-binding at the daemon: inbound data-plane frames are authorized against the trusted peer's bound public key (IsTrustedWithKey with the cached peer key) rather than node ID alone, so a node-ID reuse with a fresh key is not silently trusted. Adds panic recovery on the tunnel dispatch path and fuzz + attack-replay coverage for punch reflection and tunnel dispatch. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Runtime companion to the handshake trust key-binding PR. The daemon authorizes inbound data-plane frames against the trusted peer's bound public key (
IsTrustedWithKey+ cached peer key), not node ID alone, so a node-ID reuse with a fresh key is not silently trusted. Adds panic recovery on the tunnel dispatch path plus fuzz + attack-replay coverage (punch reflection, tunnel dispatch).Follow-up (separate PR): go.mod bumps to the new
common/beacon/handshakereleases once those land, to pull the underlying protocol-layer guards into the daemon binary.🤖 Generated with Claude Code
