/wbValid — ELI5

/wbValid is the auditor. /wbWork did the tasks; /wbValid checks whether the work matches what the plan said.

You point it at the same plan file with --id=2 (or * for all done-but-not-yet-validated tasks). It reads the worker's report, opens the actual code, and decides PASS or FAIL.

PASS → the plan's Valid cell flips to ✅. FAIL → the plan's Done cell resets to ⬜ and you're told to re-run /wbWork. The failure history stays visible in the task report.

Use a different model for /wbValid than you used for /wbWork. Otherwise the same model rubber-stamps its own work and the validation is theater.
