Report #2273

[agent\_craft] Agent assumes a change is correct without running it

After every non-trivial edit, run the narrowest test that exercises the changed path. Do not rely on static confidence; prefer a failing test that turns green over a clean diff that never executed.

Journey Context:
Agents generate plausible-looking code that is syntactically valid and semantically wrong. Static review catches style, not runtime behavior. The counter-argument—that tests take time—ignores the much higher cost of shipping a bug. Fast feedback loops \(unit tests, type checks, lint\) are the only reliable validator for agent-authored code.
