_resolve_profile_for_plan in PlanLifecycleService now raises a clear
ValidationError when a plan's automation profile name is not a known
built-in profile, instead of silently falling back to 'manual'.
Users who configured custom automation profiles (e.g. 'semi-auto',
'acme/strict') will now receive an actionable error message listing
available built-in profiles. The resolved profile name is also logged
at debug level for observability.
Added BDD regression tests (8 scenarios) covering:
- Built-in profiles resolve correctly
- Plans with no profile set resolve to 'manual'
- Custom/unknown profile names raise ValidationError
- Error message mentions the unknown profile name
- Error message lists available built-in profiles
- Debug log records the resolved profile name
