- ./check stress spins a fresh cube-server+cubec built from this tree on a throwaway socket/store and drives ~150s of real prog/run traffic while sampling the per-command latency + per-C telemetry. - tools/stress.sh: never touches the production daemon; STRESS_SECONDS override. - Fixed latent control-flow bug: the old '|| exit 0' guards made 'bench' and 'mount' subcommands unreachable after the gate (they exited early). Now uses explicit run_* flags and only exits at the true end.

# it is the only stage that exercises the real kernel VFS path. Two Package 3

|
# were caught only here — so run it before calling filesystem work done.
|

# Why `bench` is opt-in: it is a release build + timed run of cube-bench, which
|
|
# is slow and machine-noise-sensitive; it asserts correctness on every path but
|
|
# the numbers are informational, not a pass/fail gate.

# Why `stress` is opt-in: it spins a fresh daemon built from this tree and drives
