Never apply readonly to Doctrine entities or mapped-superclasses (embeddables: see references/doctrine-modernization-edges.md).
Never run Rector without --dry-run. Invoke vendor/bin/rector directly — composer script aliases can drop ---forwarded flags depending on configuration.
Never raise PHPStan level without regenerating + committing the baseline. Shrink, never delete.
Never apply blanket final to mock targets or extension points without confirmation.
Never edit @generated files or files under var/cache/, vendor/, node_modules/, .Build/.
Never git checkout -- files outside your scope in shared trees — use git stash / git diff.
Never trust a warm PHPStan cache after vendor change: rm -rf /tmp/phpstan-* var/cache/phpstan first.
Never mass-substitute createMock → createStub — promote to expects(...)->method(...)->with(...).

[ ] declare(strict_types=1) everywhere
[ ] @PER-CS, no deprecated aliases
[ ] PHPStan ≥9 (treatPhpDocTypesAsCertain: false); 10 for new
[ ] PHPat for layer boundaries
[ ] Return + parameter types on all methods
[ ] DTOs over arrays; backed enums over constants
[ ] PSR interfaces in type-hints
[ ] #[Override] (8.3+), #[SensitiveParameter] (8.2+), typed constants (8.3+)
[ ] readonly on DTOs/VOs/events only
[ ] Property hooks (8.4); array_find/any/all (8.4); pipe |> (8.5)
[ ] PHPUnit 12+: stubs use createStub, mocks createMock + expects (no self::any() in 13)
[ ] Rector withComposerBased(symfony: true) (per-version SymfonySetList::SYMFONY_* are @deprecated)
