Slow-CI simulation — run unit tests on saturated CPU to reproduce CI-style flakiness locally. Suggest when new/reworked suite lean heavy on awaits (deferFulfillment, waitForConfirmation, TestClock, timeouts) or test fail only on CI. Not for every change.

Dead-code sweep with Periphery — scan the Pro-configured project, delete unused code, guard false positives (keep-alive handles, future-use code), run unit tests, purge scan cache. Use when user want "clean up dead code", "run periphery", "remove unused code".
Reviews Swift code for concurrency correctness, modern API usage, and common async/await pitfalls. Use when reading, writing, or reviewing Swift concurrency code.

CI runners shared + slow. Background tasks starve, awaits stretch, scheduler races flake there, pass locally. --constrained saturate CPU with hog tasks — same conditions, local.
deferFulfillment, waitForConfirmation, TestClock, transitionValues, timeouts.Full unit test workflow (what CI run):
swift run tools ci unit-tests --constrained
One suite, iterate on new tests (prefer while developing):
swift run tools ci run-tests --scheme UnitTests --test-name MyNewTests --constrained
Hog count automatic (2× cores). Suite survive ~10 constrained iterations → good shape.
Failure under constraint = real bug in test (sometimes code under test): assertion race async work, transient state observation missed, timeout too tight. Fix synchronisation, no blind timeout bump. Helpers in UnitTests/Sources/TestUtilities/ (deferFulfillment, deferFailure, waitForConfirmation). Wait on durable state, not transient.
