01
Read the contract
Start with lifecycle and API guarantees, then identify behavior that varies by release or device implementation.
02
Build a probe
Use a minimal screen or demo that exposes one platform behavior without unrelated application state.
03
Keep a fallback
Capability checks and graceful alternatives make experiments useful beyond the newest configuration.
Working rule
Make the next measurement cheaper than the next argument.
Keep a minimal reproduction close to the observation. Change one variable at a time, preserve the failing path, and prefer before-and-after evidence over a broad rewrite.
