Struct WriterCounters 

pub struct WriterCounters { /* private fields */ }

Every accounting number the writer produces, held outside the task.

The tally used to be a WriterStats local on the task’s stack, materialised only when the task exited — so a process that crashed, was killed, or simply kept running reported nothing, and lost was observable only after the one kind of shutdown where loss is least likely (GL-38). Living out here it is readable at any time, and it survives the task’s death exactly as the unaccounted count always has (INVARIANTS.md GL-8).

These are also the only copy: UsageWriter::shutdown returns a snapshot of these counters rather than a parallel tally, so the running totals and the final report cannot disagree.

Relaxed throughout, like the admission counters: nothing is published through them, and atomicity — no lost increments — is all they need.
