swarm-authelia-bridge-sock

Wire types for the swarm-authelia-bridge socket — the contract between swarm-authelia-bridge (server, runs alongside swarm-authelia) and swarm-controller (client).

Why it's its own crate

Same rationale as hive-priv-sock (which this mirrors in spirit, though the transport differs — this bridge is network-facing HTTP, not a unix socket, since it has to reach a possibly-split-host swarm-controller): the bridge is a narrowly-scoped, unprivileged-but-file-owning helper, and splitting the wire contract out of any larger crate keeps both its own dependency footprint and its interface small enough to audit at a glance. No server or client logic here, only the request/response shapes both sides import.

Shape

Two operations: idempotently ensure an agent exists as an authelia subject, and list the ones that do. Deliberately not a wholesale-replace-the-file API — the bridge reads users.yml, changes what the request named, and writes it back; a caller only ever asks for one user to exist, never sends rendered YAML or a file blob. See swarm-authelia-bridge/README.md for the helper itself.
