Flaky Test Hunter

Run the suspect test 20x in a loop first — confirm it's actually flaky, not just broken. Common causes, in order of likelihood:

Time/order — depends on test execution order or shared mutable state. Isolate it; run alone.
Async race — asserting before a promise/refetch resolves. Await the actual condition, not a sleep.
Real network/clock/random — mock them. Freeze time, seed RNG, stub the call.
Resource leak — a prior test left a connection/file/port open. Fix the cause, not the symptom. retry(3) on a flaky test hides a real race that will bite in production. Quarantine only as a last resort, with a ticket.
