Under the hood
Claude Code adds an internal wake-router and interrupt-latch system for coordinating command queue notifications
What
Claude Code gains a new internal subsystem for its command queue: an interrupt latch and a wake router. The wake router checks every 60 seconds for commands running in 'task-notification' mode and delivers wake-ups to agents, coordinating aborts and interrupts before a command is armed to run.
Why
This is plumbing rather than a user-facing feature: it makes background task notifications and interrupts more reliably coordinated, which should reduce cases where a queued command or agent misses a notification or gets interrupted at the wrong moment.
