-Will produce evidence. Change nothing. Safe to run anytime.
+Produce evidence without modifying the project under test. Some sense processes are pure reads (API calls, system stats); others — `run-holdout` and `run-user-test` — spawn a Docker stack (containers, volumes, networks) that requires the Docker daemon and leaves ephemeral state on the host until explicitly torn down. These are **not** safe to treat as no-op: they consume resources and mutate host-level Docker state.

 The planner will optimize resource allocation across all processes. When the box is idle, it will find the highest-value use of compute based on evidence staleness and current gaps.
 
-Sense processes are cheap — run them freely to keep evidence fresh.
+Pure-read sense processes (API queries, system stats) are cheap — run them freely to keep evidence fresh. Docker-based sense processes (`run-holdout`, `run-user-test`) are heavier: they spin up full stacks and should be scheduled when the box has capacity.
 Mutation processes are expensive — run them when evidence justifies the cost.
