practical guidance Shipped
What this lens looks for
Make the principle actionable: how to apply it, what it trades off, and the failure mode it prevents. Prefer concrete over abstract. Drop any guidance you cannot defend with a real cost it avoids — advice without a failure mode is noise.
What its verifier checks
Guidance is actionable, not abstract; every piece names a real trade-off or failure mode; nothing remains that cannot be defended by a concrete cost it prevents.
