Applying PL/SQL Changes
Announce at start: "Using pythia-apply — I'll preview the change first."
Phase: Ask → Do — the preview is relayed and approved before the one write door opens
DDL in Oracle commits itself, so the snapshot pythia takes before writing is the only undo there is — for DML not even that. This skill is how it gets used.
The Iron Law
NO WRITE THE DEVELOPER HAS NOT SEEN AND APPROVED
Every write: new objects, fixes, restores, batch runs. No exception for "trivial" — a one-line change can invalidate twelve dependents.
