Module known_hosts 

TOFU persistence of host-key fingerprints under XDG.

Line-oriented format (0o600): host:port <fingerprint_sha256>

Concurrency (G-PAR-49)

Multi-host fan-out can run N first-connect TOFU writes against the same file. Every mutating path takes an exclusive flock on a sibling *.lock file, reloads disk state, merges, then atomic-persists — same pattern as crate::vps::save for config.toml.

Structs

Map of host:port → fingerprint.

Functions
