Odoo becomes the accounting SoR by ingesting NexaCloud's real Stripe
invoices (read-only via the existing DSN) into native account.move
customer invoices: per-service-family income accounts, tax derived to
match the source invoice.tax, Stripe payments reconciled via
account.payment.register (invoice shows paid), idempotent on
x_fc_nexacloud_invoice_id, draft-first with bulk-post + a daily cron
(inactive). Plus a prune helper for the now-obsolete metered shadow data.
73 tests green on odoo-trial. Account codes use dots (Odoo 19 rejects '-').
fusion.billing.import.wizard backfills NexaCloud into Odoo: read-only
psycopg2 reader (_read_nexacloud_rows, DSN from ir.config_parameter)
split from pure-Odoo writes (_import_rows/_do_import) so the logic is
unit-tested headless. Maps users→partners+links (reusing
_resolve_or_create_partner, stashing stripe_customer_id), plans→a
cpu_seconds charge catalog (included_quota=cpu_seconds_quota,
unit_batch=3600, $0.0075/core-hour, plan_id NULL), and deployments→one
DRAFT shadow sale.order per deployment with the flat price set
explicitly. Shadow-safe by construction: draft + no payment token +
charge plan_id NULL (rating cron is a no-op). Idempotent re-runs;
per-row savepoints isolate bad rows; dry-run rolls back. 11 tests,
50/50 green on odoo-trial.
