// Aborts a single Sync Box request (all retries included, since fetch-retry

// for the first attempt, plus up to HTTP_RETRY_COUNT retries of real
// (non-abort) network errors backing off at HTTP_RETRY_BASE_DELAY_MS *
// 2^attempt each. Must stay comfortably above that worst case - if a job
// legitimately runs longer than this, async-lock hands its slot to the next
// queued caller while the original request keeps running in the background,
// which can let two requests execute concurrently against the lock's
// mutual-exclusion guarantee.

// ===== Sync Box Client Security Constants =====
// The Sync Box's cert is accepted without identity verification, so a
// LAN-adjacent attacker able to spoof its address could otherwise return an
// unbounded body and exhaust the shared Homebridge process's heap before
// isValidState() ever runs. Legitimate state responses are a few KB.
