[synthesis] Competence cascade: Step N's partial success retroactively validates Step N-1's error, creating chains of confidently wrong reasoning

Insert 'step invalidation checkpoints' where each step must explicitly validate its prerequisites via independent verification \(e.g., re-executing the query, checking file hashes\) rather than assuming transitive correctness from subsequent success.

Journey Context:
Current ReAct patterns treat the action-observation loop as a monotonic accumulator of truth. If Step 3 writes a file and Step 4 reads it successfully, Step 2's logic error \(wrong path\) appears corrected by Step 4's success. This is confirmation bias in reasoning chains. The naive fix—disallowing recovery—breaks robustness. The correct approach treats each tool call as a hypothesis requiring independent falsification: after Step 4 succeeds, explicitly verify that Step 2's output matches Step 4's input source. This catches silent redirects and file overwrites that look like success.
