ng-migrate

Angular ships official migration workflows that rewrite code deterministically. This skill owns both Angular version updates (this repo's pnpm ng:update script, wrapping ng update) and opt-in ng generate @angular/core:* modernization schematics.

For modernization schematics, run one migration at a time, each over a chosen scope, each verified by the full gauntlet and committed at a clean checkpoint before the next. Prefer these schematics over hand-editing – they update every reference (templates, tests, call sites) that a manual edit would miss.

For Angular package updates and their automatic version migrations, follow references/ng-update-migrations.md. The same clean-tree preflight, gauntlet, and checkpoint discipline applies.

Hard rule: planned migrations are not optional
