-- Кастомные статусы канбана — order_statuses replaces the fixed
|
||
-- orders_status_check enum with an owner-editable table. `key` is the
|
||
-- permanent identifier every existing piece of backend logic already keys
|
||
-- on (internal/order's "completed"/"cancelled"/"ready" transition side
|
||
-- effects, internal/scheduler's warranty reminder, internal/analytics'
|
||
-- turnaround calc, internal/booking's initial-status event log) — it is
|
||
-- deliberately NEVER exposed as editable. `label`/`color`/`sort_order` are
|
||
-- the owner-facing surface (rename, recolor, reorder) via internal/order's
|
||
-- new status CRUD. system_role is informational only (lets the UI flag
|
||
-- "Новая"/"Готово"/"Выдано"/"Отменено" as behaviourally special before an
|
||
-- owner deletes one) — nothing in Go queries it; the special-case logic
|
||
-- matches on `key` directly, same as before this migration, since key
|
||
-- never changes even when label does.
|
||
--
|
||
-- Deleting a status is only possible once no order references it anymore
|
||
-- (the FK below is RESTRICT, not CASCADE/SET NULL) — same "can't delete
|
||
-- something in use" behavior as every other reference table in this
|
||
-- schema, no extra guard needed even for the four system_role rows: an
|
||
-- owner who really wants to delete e.g. "Выдано" first has to move every
|
||
-- order out of it, at which point the handover side effects in
|
||
-- internal/order simply stop firing for future orders (no status carries
|
||
-- that key anymore) — a real capability tradeoff they're accepting on
|
||
-- purpose, not a bug.
