Centralize billing for all NexaSystems services (NexaCloud, NexaDesk, NexaMaps, custom apps, memberships) on the Odoo 19 Enterprise instance, replacing Lago. The module adds only the metering + integration layer; native sale_subscription / account_accountant / payment_stripe do all the financial work (invoicing, HST, dunning, portal, credit notes, Stripe). Includes: - Design spec (docs/superpowers/specs/2026-05-27-nexa-billing-centralized-design.md): 6 locked decisions, architecture, data model, usage engine, Lago-shaped API, webhook control loop, NexaCloud pilot, phased dual-run migration. - Module scaffold: 7 fusion.billing.* models (service, account.link, metric, charge, usage, webhook, reconciliation), bearer-auth API controller shell, security ACLs, README. Compiles on Odoo 19.0; engine/API bodies are stubs pending the implementation plan. - CLAUDE.md rule #15: no sale.subscription model in Odoo 19 — a subscription is a sale.order(is_subscription) + sale.subscription.plan (verified live). Task 0 verified: a single Stripe account is shared across NexaCloud and all Lago providers, so no Stripe account/card migration is required.
