Four things the programme form could not say, all of which sent the desk
somewhere else or nowhere at all.

A timetable. Recording that a group trains Sunday and Tuesday from four to
half five required the visual grid, which demands a facility and a space —
so clubs that place nobody on a grid had no timetable at all, and the
proration and attendance engines had nothing to read. The form now writes
plain TrainingSchedule rows on the programme's default group with
facility_id null. Rows the grid HAS placed are left alone: clearing a
checkbox here must not strip a space reservation off a scheduled session.
A day dropped from the selection is deactivated rather than deleted,
because generated sessions hold a hard FK to the row and attendance hangs
off those sessions.

Renewal defaults. A new programme opened as manual_renew, so every one had
to be corrected by hand or quietly stopped billing. It now opens
auto_renew, monthly, on the first.

Kits. program_products already records 'this player must buy that thing',
but only for a single product; a kit sold as one thing could not be
required. program_kits is a separate pivot rather than a nullable kit_id
on program_products, whose product_id is NOT NULL and whose uniqueness is
(academy, programme, product). Nor is a kit expanded into its components:
the POS writes an invoice line carrying itemable_type = Kit, so a
programme requiring the parts would report every buyer as missing all of
them. The group roster flags a missing kit the way it flags a missing
product.

Prices. The programmes list showed no price, so comparing what two
programmes cost meant opening both. Both tiers now show, in one query for
the page, and a tier with no active base price reads 'غير محدد' rather
than 0 — the engine hard-fails there, so a zero would be a figure nobody
will ever be charged.
