Report #2278

[agent\_craft] Agent trusts its own previous plan after new evidence contradicts it

Treat the plan as a hypothesis, not a promise. When tests, logs, or code inspection reveal unexpected structure, stop and revise the plan before continuing. Never ignore a failing check to preserve momentum.

Journey Context:
Sunk-cost bias appears in agents too: having emitted a plan, the model continues executing it despite red flags. This produces layered bugs and convoluted workarounds. The corrective is explicit replanning triggers: a failed test, a missing symbol, or an unexpected API response should pause execution and regenerate the next steps.
