+"""VIOLET V2: ExecDeadlineDriver — event-driven TTL resolution at 100 ms.
+
+Lifts the PINK TTL-resolution logic (pink_direct.py `_exec_after_submit` /
+`_exec_ttl_loop` / `_handle_expired_working`, proven live) out of the
+runtime into a standalone driver with injected ports, and replaces the 1 s
+polling sweep with ONE DeadlineScheduler deadline PER WORKING ORDER —
+sub-second TTLs with measured jitter instead of polling quantization.
+
+Timing authority note: the shared ExecutionRouter clamps TTLs to >= 0.5 s
+(ExecConfig.from_env [0.5, 300] + register_working's max(0.5, ttl_s)
+floor). This driver therefore NEVER polls router.expired(); it schedules
+its own deadlines from ExecDriverSettings.ttl_ms_for(plan.ttl_s) and uses
+the router purely as policy authority (plans, miss policy, retry/fallback,
+registry pop-semantics). The router's internal WorkingOrder.deadline is
+vestigial here.
+
+Concurrency: asyncio single-threaded cooperative. Re-entrancy between a
+deadline fire and a fill notification is handled by (a) the `_resolving`
+single-flight set, (b) the router's pop-semantics (`note_fill`/`note_cancel`
+make double resolution a no-op), and (c) a state re-check after every await
+(fills race cancels on a live venue — same doctrine as pink_direct).
