// phase 3 · observability · status: planned · published [date]

The goal of this step

In-kernel stats on the same audio path eBPF is already watching: file_operations, ioctl, sysfs, and correct locking — the inside view to set against the outside one.

What I did

[ first concrete thing ]
[ second concrete thing ]
[ third concrete thing ]

The tricky part

[ The one thing that actually cost time. Be specific and honest — this is the section readers remember. ]

# [ the handful of commands / code that matter — keep it copy-pasteable ]

Honest note: [ anything simulated, stubbed, or deferred at this stage — state it plainly. ]

Result

[ The concrete, verifiable win for this step, and what it unlocks for the next one. ]
