Five places where the data existed and the screen did not use it.
Booking a whole course had no button because it needs a doctor and the course
does not carry one — each session can be with a different doctor. The page now
asks for the doctor the same way the resource booking page does, and the button
explains that it is all-or-nothing before it is pressed.
A course whose package does not cover the remaining sessions is still valid —
the rest is simply charged normally — but nobody was told. The course response
carries package_balance and the shortfall, and the page warns. Before session
six, not during it.
The credit ledger already returned who recorded a row and which appointment it
belonged to, and showed neither. An adjustable ledger without the name of the
person who adjusted it is half an audit trail.
Version history printed a JSON blob of each version's effects, which does not
answer the question anyone actually has: what changed? It now diffs each
version against the previous one, field by field, and says so plainly when a
version changed nothing meaningful.
A resource with no calendar showed "—" for utilization. Null means undefined,
not zero, and the next step is always the same: set up the calendar. It is a
link now. The report range also accepts a custom from/to, kept in the URL like
the rest.

Task 09 shipped a powerful API that a non-technical clinic owner could not
safely use. This closes that gap: activation now requires having seen what the
rule actually does.
- PolicySimulator runs a policy against real past appointments and writes
nothing: evaluation works on facts (never entities), the whole run sits in a
transaction rolled back and cleared in `finally`, and a test counts rows in
five sensitive tables before and after
- activate() now demands a simulation of the *same version* — a report for
version 1 does not unlock version 2
- PolicyTemplateRegistry: six ready-made rules, so the common case never
touches a raw condition
- Severity from the affected ratio; 0% is a warning too, since a rule that
changes nothing usually has a condition that never matches
- An empty clinic still succeeds with a warning, otherwise a new clinic could
never activate anything
Admin: PoliciesPage, PolicyFormPage, PolicySimulationPage, and a
PolicyConditionBuilder built entirely from GET /policy-schema — a test proves a
field that exists only in the schema shows up with no frontend change, and that
operators are filtered per field type.
The schema response now carries per-field metadata (label, type, meaningful
operators) so the form has one source of truth instead of two.
