Adds bank_rec_bootstrap step that backfills fusion.reconcile.precedent
from existing account.partial.reconcile rows during migration. This
gives the AI memory from past Enterprise reconciles. Also triggers
pattern refresh + MV refresh for immediate UI readiness.
- New service services/precedent_backfill.py walks
account.partial.reconcile rows, identifies the bank-statement-line
side, and creates a precedent per qualifying partial. Idempotent via
(statement_line, account, amount, source='backfill') signature.
- New model models/fusion_migration_wizard.py inherits
fusion.migration.wizard, exposes _bank_rec_bootstrap_step() (callable
from tests/audit), and overrides action_run_migration() to call
super() + the bootstrap.
- Adds 'backfill' to fusion.reconcile.precedent.source selection.
- Adds fusion_accounting_migration to depends.
