Implements BILLING.md. The architecture was sound -- snapshot-on-Due, dated prices, asymmetric dry-run commands are all kept -- so this fixes the three hardcoded assumptions rather than rewriting. The real defect: grace ran from period_END, so an annual club used the whole unpaid year plus 45 days (~410 days) before anything switched it off. Grace now runs from the period START, and every clock is per-plan. - Tier -> Plan (+ TierPrice -> PlanPrice, and every FK). Migration 0004 is hand-written: run non-interactively, makemigrations emits DeleteModel+CreateModel and drops every price, subscription and due. Its two RemoveConstraints must come first, or SQLite's table-rebuild tries to render a constraint over a just-renamed column. Verified by round-tripping real rows through it. - Plan gains duration_months / renewal_lead_days / grace_days / is_trial, with CheckConstraints and a matching clean() so the form reports an impossible plan instead of 500ing on IntegrityError. - Existing dues keep their stored grace_until. Re-deriving it would put the date in the past for every open annual period and archive the entire paying customer base on the next --commit run. - Trials take their length from the trial plan's own duration_months; start_trial() loses its trial_months argument. - New BillingNotice service drives a club-facing warning: every level on the dashboard, and on every management page once urgent. - send_billing_reminders emails club admins, once per escalation level so a daily cron is not a daily email. SMTP settings are env-driven and provider-agnostic; the backend defaults to console. - Paying does not auto-restore an archived club -- the control panel surfaces a Reactivate prompt instead, since a club can also be archived by hand.
