   Decision (2026-10-18): this stays blocked. It needs #78, which waits for omx-contract#94, and it needs the D7 idle-gate thresholds, which nothing I can read fixes. Before the idle gate can be built, someone has to rule on four things:

   1. The quiet window: how long the console must have had no busy lease and no client command before a probe may start. Is it a key (probe_idle_quiet_ms?) and what is its default?
   2. The load threshold: which figure (loadavg 1 min, or PSI cpu some avg10), compared with what (an absolute value, or a share of the cpus not given to the engine), and its default.
   3. The cpus off the engine: where the daemon learns which cpus the engine owns (a key listing them, the engine's cpuset, or worker_env cpus) and what it does when none are free.
   4. auto_measure is off by default (D2): may a request file or probe_request run while it is off, or does it only queue?
      No code until these are decided.

   • Declare the quanta (buffer sizes) the way the rates are declared omx-contract#94
