windags-looking-back

Polya's four questions after every WinDAGs execution. Q1 (contract satisfied?) and Q2 (unstated assumptions?) are mandatory on every DAG. Q3 (generalizable?) and Q4 (broader connections?) are conditional on quality and cost thresholds, run asynchronously, and never delay result delivery. Activate on "looking back", "Polya", "retrospective", "post-execution review", "was the contract satisfied", "unstated assumptions", "generalize", "problem class". NOT for learning engine updates (use windags-curator), failure scanning (use windags-premortem), or DAG construction (use windags-architect).
