Bounded stress experiments should reveal failure and recovery.

Ordinary load asks whether the system handles expected demand. Stress
testing asks what happens when a selected limit is pushed.
That second question deserves careful permission and containment.
/carbon-stress starts with read-only source and
configuration inspection, then proposes bounded stress and recovery
experiments. A useful local tight loop may reveal more about one suspect
component than an uncontrolled blast at a remote site.
Pick a failure mechanism
Suppose repeated parsing retains memory. An isolated component
experiment can vary input size and iteration count while observing
resource use and correctness. Another experiment might test queue
saturation using a bounded test double.
The goal is to understand the limit, the resulting behavior, and
whether recovery works. Filling the user's disk or exhausting the
machine is not an acceptable shortcut.
Permission applies
to the real dependencies
/carbon-stress inspect the local parser for resource-growth risks; propose a sandboxed tight-loop experiment with hard time and memory limits
Approved local execution still needs containment. Anything beyond
verified isolated localhost requires two distinct confirmations:
preparation scope first, then the exact workload and consequences before
execution. A local URL connected to a shared database is not isolated
merely because its hostname looks reassuring.
The report should preserve the conditions, observed failure, stopping
reason, and recovery evidence. It should not claim an experiment ran
because a harness was generated.
The valuable result is knowing how the system behaves near a limit
without giving the test permission to cross every other boundary.
