Report #1073

[agent\_craft] Wrote code and assumed it worked without executing it

Run the tests, linter, or start the service after making changes; a green check is the only reliable proof.

Journey Context:
Agents can produce plausible-looking code that fails on syntax, imports, or logic. Static inspection scales poorly with context length, and models are not reliable debuggers of code they just wrote. The antidote is execution: run pytest, run the smoke test, start the dev server, or invoke the script. This is not optional cleanup—it is part of the edit loop. The cost of one run is far less than the cost of shipping a broken fix. If the project has no tests, run the module directly with a minimal command; never leave a change unverified because it 'looks right.'
