Exits move off the single-threaded scheduler onto their own daemon thread at 1s (mirrors the fast trigger thread). Dedicated research connection (shared facade isn't thread-safe); scheduler exits step auto-disabled when the thread runs (single-caller invariant — no racing instance state, no double-submit); manage() already idempotent (stop ratchets >1c up only). 3 driver tests + 539 suite green. On fast small-caps this is the 'get out fast' the owner asked for. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
