Report #4800

[agent\_craft] Shipped code that compiled but failed in production because no test or script was run after the change

After every non-trivial edit, run the smallest relevant verification first—unit test, linter, or type-check—then broader suites only when the narrow one passes.

Journey Context:
Syntactic correctness is not semantic correctness. A missing import or subtle logic error is invisible to the model but obvious to a test. Running a slow full suite after every change kills iteration speed; instead run the closest test. The antipattern is 'I can see it's correct' or deferring verification to the user.
