// AZ-466 — Destructive UX policy (cross-component half)
//
// AC-1 (FT-P-26): clicking Delete on a class → confirming → DELETE fires AFTER confirm.
// AC-2 (FT-N-07): clicking Delete → Cancel → NO DELETE fires.
// AC-4 (FT-P-27 / NFT-SEC-08): static check enumerates every destructive surface
//                              and asserts each one mounts a `<ConfirmDialog>`.
//                              The static side lives in `scripts/run-tests.sh` /
//                              `scripts/check-banned-deps.mjs` (`STC-SEC8`).
//                              The runtime mirror is one of the cases below.
// AC-5 (NFT-SEC-07): no `alert()` in `src/`. Static side enforces this; runtime
//                    side here only documents the current allowlist. The runtime
//                    test would require renderring every component that calls
//                    alert — out of black-box scope. Static check `STC-SEC7`
//                    handles enforcement.
//
// Production drift (`src/features/admin/AdminPage.tsx:30-33` and table row
// line 76):
//   `handleDeleteClass` directly calls `api.delete` without gating through
//   `<ConfirmDialog>`. The class-delete row's `<button onClick=...>` triggers
//   the network mutation immediately. FT-P-26 + FT-N-07 are recorded as
//   `it.fails()` until production wraps `handleDeleteClass` behind ConfirmDialog
//   (Phase B feature task).
