Task 20 of Phase 0: document the sub-module split.
- fusion_accounting_core: foundation doc covering security groups, shared-field
schema preservation, and the Enterprise-detection helper.
- fusion_accounting_ai: preserves the original module's AI-specific design
decisions, Odoo 19 gotchas, deployment commands, controllers, models, theme
rules, and known issues. Adds a new Data-adapter pattern section documenting
tri-mode routing (fusion / enterprise / community).
- fusion_accounting_migration: doc for the Enterprise uninstall safety guard
and the wizard shell that future feature sub-modules will extend.
- fusion_accounting (meta): rewritten CLAUDE.md as a pure overview pointing at
sub-modules, plus a new README.md covering one-click install/uninstall.
Each sub-module now has CLAUDE.md (Cursor/Claude context), UPGRADE_NOTES.md
(version-by-version deltas / reference sources), and README.md (user-facing
install/usage docs). 11 files total.

Task 16's security group rehoming (fusion_accounting → fusion_accounting_core)
only existed in post-migration. That flow fails on fresh pre-Phase-0 upgrades:
data-load runs before post-migration and looks up group xml-ids by
(module, name); if the row still has module='fusion_accounting', Odoo
creates a duplicate res.groups record under
module='fusion_accounting_core'. The subsequent post-migration
UPDATE...SET module='fusion_accounting_core' then trips the (module, name)
unique constraint on ir_model_data, rolling back the whole transaction.
Pre-migration runs BEFORE data-load, renames the five security xml-ids
(module_category, privilege, three groups) to the new module, so data-load
finds the existing rows and UPDATEs them in place. Existing user-group
links via res_groups_users_rel are preserved.
The post-migration is kept as an idempotent safety net (docstring
updated to reflect the new division of labour).
Verified on westin-v19 by simulating the pre-Phase-0 state (UPDATE
ir_model_data SET module='fusion_accounting' ...) and re-running the
upgrade: 5 rows renamed cleanly, zero duplicates, no errors.
