const UI_AUTOMATION_SIG_MAX_AGE_SECS: i64 = 300;Expand description
Signatures older than this are rejected — bounds replay of a leaked/
logged signature to a short window. Mirrors server/reactive.rs’s
JEKT_SIG_MAX_AGE_SECS (same threat model: a host-tier HMAC signature
verified locally, not a one-time nonce scheme).
