Laser is six to eight sessions; the previous design only knew single
appointments, which is the exception rather than the rule.
- CourseProtocol per service: session count and three distinct spacings —
min is the earliest that is clinically allowed, ideal is best, max is where
the course starts losing its effect
- Starting a course creates every session up front as `planned` and copies the
protocol's numbers and per-session params, so changing the protocol tomorrow
leaves a running course alone
- Suggestions anchor on the last *completed* session, not the course start:
when session 2 slips, session 3 moves with it
- Slots are ranked by distance from ideal, not by earliest available — day 21
is worse than day 27 when 28 is the target
- book-all is all-or-nothing inside one transaction, with a moving anchor and a
90-day horizon; sessions past the horizon stay planned and are reported, not
treated as failures
- The effective minimum is the stricter of the protocol and the task-09 spacing
policy, so a clinic rule never fights the protocol
- Cancelling one session returns only that session to planned; abandoning a
course does not cancel its appointments, which stays an explicit decision
One active course per (patient, service) via active_course_key, the same
partial-uniqueness trick as Appointment::activeSlotKey.
