- loadtest/soak_sync.py + mock_provider.py: fully isolated soak for acceptance criterion 7. Creates a throwaway webmail_soak DB + uses Redis DB 14 (both torn down), simulates N accounts (default 1000, 20% active sessions) across 3 in-process coordinators with a mock MailProvider (no real IMAP). Asserts: all accounts owned, persistent sockets <= hot*1.05, oldest lag < POLL_COLD*1.15, RSS stable. Steady state = after every account has completed its first sync. Configurable via SOAK_* / POLL_* env for fast smoke runs. - engine: poll_all_loop and secondary_poll_loop now jitter their waits (first at a random point in the interval, later +/-10%) so a fleet claimed together doesn't poll in lockstep — anti-thundering-herd, a real improvement surfaced by the soak. Validated: 60-account smoke passes all four criteria; full gate green (238 tests). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
