Report #101562

[agent\_craft] Agent assumes an edit succeeded and moves on, leaving silent mismatches or broken tests

After each edit, read back the changed region and run the relevant test, lint, or build command before the next step.

Journey Context:
Exact string replacement can match the wrong block or silently fail when whitespace shifts. Without a verification gate, errors compound across turns. Aider's lint/test-on-edit feature and the blind-edit issue in Claude Code both show that 'edit applied' is a hypothesis until a read-back and a passing check confirm it.
