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.
