What we're designing

A native bank-rec widget that replaces Odoo Enterprise's account_accountant bank reconciliation, using Odoo 19's frontend OWL architecture. It reads/writes the same account.partial.reconcile tables Community owns, so existing reconciliations are immune to Enterprise uninstall (verified empirically in Phase 0).

Reference material I've already scanned

• Roadmap design Section 4.3 — Phase 1 scope, exit criteria
• Enterprise V19 source at RePackaged-Odoo/accounting/account_accountant/ — 17 OWL components in static/src/components/bank_reconciliation/, 1 service file (140 lines), 3 inherits on community models, 2 wizards
• Phase 0 BankRecAdapter — already present at fusion_accounting_ai/services/data_adapters/bank_rec.py with a stub list_unreconciled_via_fusion() waiting to be filled in

How this session works

1. I ask clarifying questions one at a time (terminal for scope/concept, this browser for layout/visual)
2. I propose 2-3 architectural approaches with tradeoffs
3. We work through the design section by section
4. I write the spec doc and you approve it
5. Then we transition to writing the implementation plan
