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
