"""Drop the legacy Machine instance layer
|
|
|
|
Retires the Machine model (ADR-001): the asset/computer model is now the
|
|
single source of truth. Drops machines + its PC/status lookups + the legacy
|
|
relationship and installed-app tables + the legacy printer extension, and
|
|
removes the deprecated communications.machineid column. machinetypes is kept
|
|
(still referenced by models.machinetypeid).
|
|
|
|
Idempotent (IF EXISTS) so it is safe even though the live drop was applied
|
|
directly during the cutover.
