When a successful profiled task or dependency is not wrapped with trace.exec, its stderr still goes only to devenv-verbose.log, which is replayed only if the overall Devenv command fails; native Devenv warnings are suppressed the same way. The fresh evidence in this revision is that stderr restoration was added only inside traceExec (tasks/lib/trace.nix:175-177), so the static regression check does not cover unwrapped tasks even though this redirect encompasses the entire nested invocation. Preserve non-verbose stderr independently of whether a task uses the Effect bridge.

Problem
The shared setup trace verifier requires native Devenv root and task spans, but its nested Devenv invocation does not enable the verbosity level at which Devenv 2.2.2 records task activities. A successful
setup:gatetherefore produces only the independent Effect bridge span and the verifier exits 1.Goal
Make the shared verifier capture the native spans it already asserts, without weakening its trace-structure contract.
Decisions
--verboseonly inside the hermetic capture boundary. This preserves normal task output while asking Devenv to record task activities for the verification run.Verification
bash nix/devenv-modules/tasks/shared/tests/observability-capture.test.sh- pass.CI=1 devenv tasks run check:quick --no-tui- pass (PTYeffect-utils.otel-verifier.check-quick, exit 0).json:filetrace forsetup:gateat default verbosity; adding-vwrites native root/task activities.schickling.devverifier against this exact revision is being run before handoff.Complexity
No new abstraction or dependency; one capture flag and one regression test.
Concerns
Verbose recording can produce more trace data during explicit profile/verification captures. It is scoped to those captures.
Friction & bottlenecks
The failed verifier emitted only
{}because its intermediate assertions suppressjqoutput. The preserved capture and a JSON-file falsification were needed to identify the absent native producer.Follow-ups
None.
