Closes the four gaps the security review surfaced: - OS permission model on the prod plugin child (Node --permission with fs-read scoped to the compiled server dir + the plugin's own code dir, no fs-write/child_process/worker/native). A plugin can no longer read trek.db or the .jwt_secret/.encryption_key files, nor shell out — the direct-fs and RCE escapes that bypassed the RPC layer. Opt-out via TREK_PLUGIN_PERMISSIONS=off. - Egress guard extended from fetch to the net.Socket connect choke point, so node:http/https/net/tls obey the declared-egress allowlist too (no declared egress = no outbound). Under the permission model there is no clean escape to an unwrapped runtime. Kernel/network-namespace containment remains the container step. - Trip reads are membership-checked against the acting user the HOST binds from the authenticated invocation, not an asUserId the plugin supplies; a job/onLoad (no user) can't read user-scoped trips. - Optional minisign (Ed25519) author signatures verified offline, TOFU-pinned (migration 158). Unsigned plugins install on sha256 alone; a signed plugin can't silently drop its signature or swap its author key. Server suite green (permission-model activation verified against the Koffi reference plugin on dev1).
