Which @angular/* package(s) are the source of the bug?

core

Is this a regression?

Yes

Description

As stated in errors.ts:

 * Error code ranges per package:
 *  - core (this package): 100-999
 *  - forms: 1000-1999
 *  - common: 2000-2999
 *  - animations: 3000-3999
 *  - router: 4000-4999
 *  - platform-browser: 5000-5500

The issue is that two errors (introduced in #50980) are breaking above ranges:

  RUNTIME_DEPS_INVALID_IMPORTED_TYPE = 1000,
  RUNTIME_DEPS_ORPHAN_COMPONENT = 1001,

(https://github.com/angular/angular/blob/main/packages/core/src/errors.ts#L120-L122)
as they relate to core package, whereas 1000-1999 are restricted to forms.

Moreover, error codes 1000 and 1001 already exist:

  // Structure validation errors (10xx)
  NO_CONTROLS = 1000,
  MISSING_CONTROL = 1001,
  MISSING_CONTROL_VALUE = 1002,

(https://github.com/angular/angular/blob/main/packages/forms/src/errors.ts#L16-L18)

Anything else?

Possible solution: restrict codes 950-999 to relate to:

  // Runtime dependency tracker errors (950-999 range)
  RUNTIME_DEPS_INVALID_IMPORTED_TYPE = 950,
  RUNTIME_DEPS_ORPHAN_COMPONENT = 951,
