Adds the brainstormed roadmap design that turns fusion_accounting from an AI-only extension into a full replacement for Odoo 19 Enterprise accounting (account_accountant, account_reports, accountant, account_followup, plus selected satellites) for Nexa client deployments. Covers: - Sub-module topology (9 modules + meta-module): _core, _bank_rec, _reports, _dashboard, _followup, _assets, _budget, _ai, _migration - Data preservation strategy: bank reconciliations verified preserved automatically (live in Community account.partial.reconcile); shared-field-ownership pattern for Enterprise extension fields on account.move; pre-uninstall migration wizard for Enterprise-only tables - Phased roadmap: Phase 0 foundation through Phase 7+ optional satellites, with Bank Rec as Phase 1 priority and Reports as the largest phase - Architecture rules: hybrid mirror/abstract zones, fusion.* naming, runtime coexistence detection, zero hard Enterprise deps - Cross-version upgrade workflow: pinned Odoo source snapshots per version, annual diff ritual, UPGRADE_NOTES.md per sub-module - AI integration via adapter pattern (current AI tools route through adapters that prefer fusion native, fall back to Enterprise, then to pure Community) - Testing strategy, security, performance, multi-company/currency, localization, hosting Implementation of each phase happens in subsequent sessions, each with its own writing-plans pass starting with Phase 0 Foundation.
