Fable Recover

Stop spending mutations on a failing hypothesis. Rebuild causal confidence before changing code again.

Mission

Recovery exists for the moment an agent is most likely to become expensive and irrational: the same task has failed more than once, output contradicts expectations, or edits appear to have no effect.

The goal is not to "try something different." The goal is to explain why previous attempts failed, falsify competing causes, and issue one repair that is justified by new evidence.

Activate When

• the same command/test/behavior fails after two materially similar implementation attempts;
• output appears stale or unaffected by known source changes;
• tests/runtime disagree;
• evidence contradicts a load-bearing assumption;
• failures alternate or depend on timing/environment;
• the agent is about to repeat a command/patch without new diagnostic information.
