- Removed package consumption flags and related properties from PriceQuote.
- Eliminated unused domain event publishing for policies and waitlist in Schedule.
- Cleaned up BookingEngineSeeder by removing package and policy related logic.
- Updated SeedScenariosCommand to reflect removal of policies from output.
- Dropped policy, package, treatment course, cancellation, waitlist, and domain event tables in migration.
- Removed domain event assertions from tests related to resource blocking.
Tasks 07 through 13 each changed something the rest of the system might want
to know about, with no contract for saying so. And task 05 shipped a powerful
segment editor with no feedback on whether a clinic defined its segments right.
Events
- A closed list of names, because a consumer branches on the string and a
one-letter typo would produce an event nobody hears and no error either
- Payloads carry uuids and scalars only; non-scalars are dropped, not
serialised, so a consumer always fetches fresh rather than reading a stale
detached entity
- record() deliberately does not flush: the event row commits with the change
it describes, so a rolled-back transaction leaves no event behind. A test
pins exactly that
- app:events:publish drains the outbox; five failed attempts park a row with
its error rather than deleting it, because a silently dropped event is a
loss with no trace. app:events:prune only ever removes published rows
Reports
- Resource utilisation separates available, occupied and active minutes.
The gap between occupied and active is what exposes a bad segment
definition, and available is multiplied by capacity so a three-chair room
does not read as permanently over 100%
- A resource with no calendar reports utilization: null, not zero — dividing
by zero means something different from being idle
- Plan accuracy compares planned against actual duration per service and
flags both directions: running short wastes capacity that could have been
sold. Its row links straight to editing that service's segments, because a
report with no route to a fix does not get read

Section 11 and the third closing rule of the design document: preventing a double
booking is the database's job, not the code's. Any "is it free?" check in PHP has a
race window between the read and the write — two concurrent requests both see free
and both write.
MariaDB has no range EXCLUDE constraint, so every occupied interval is broken into
fixed five-minute buckets under UNIQUE(resource_id, bucket_at, seat). The code only
INSERTs; a rejection from the database *is* the answer. `seat` carries capacity: a
three-bed room has seats 0..2, allocation walks upward on each collision, and the
fourth concurrent hold finds nowhere to sit. Counting capacity in PHP would have
rebuilt the very race this removes.
Buckets are written through DBAL rather than the ORM on purpose: a unique violation
raised inside flush() closes the EntityManager, and the next seat attempt would then
fail with "EntityManager is closed", hiding the real outcome.
Occupancy is one row per (segment × resource). The reference test asserts the payoff
directly: for a 55-minute appointment of numbing / waiting / laser, the room gets
three rows and the operator only two — the operator holds nothing during the wait and
stays bookable for someone else.
A partial hold never survives. If the second resource has no room, the first is
released and the hold itself removed; otherwise a resource stays locked for an
appointment that will never exist.
Confirming does not re-reserve anything — the seats were taken at hold time and only
the label changes. Re-reserving on confirm would reopen the race the hold closed.
Cancelling marks rows `released` instead of deleting them, because the history of
which resource was busy when is the input to the utilisation reports; the uniqueness
buckets *are* deleted, or that interval would stay locked forever.
Expired holds are released by the existing scheduler rather than a new one. That
exposed a bug in my own change: the flush guard used $count, which now includes
released holds, so reset([]) could pass false to save(). It is guarded on $expired.
The appointment itself is still built with the existing constructor, so
active_slot_key, events and the payment path behave exactly as before — the
multi-resource occupancy sits beside them, not instead of them.
12 tests. Two matter most: the second hold on the same resource and interval getting
409, and a test that writes a duplicate bucket row over a *separate connection* and
expects the unique-key violation — if that one ever passes silently, the guarantee
had moved back into the code.
1208 tests / 3495 assertions. phpstan at its 14-error baseline. Frozen slot contract
green.
