+"""Reassign ir_model_data ownership from fusion_accounting to fusion_accounting_ai.
+
+Pre-Phase-0, all fusion code lived in module='fusion_accounting'. Post-Phase-0,
+fusion_accounting is the meta-module and the AI code lives in
+'fusion_accounting_ai'. Odoo loads the Python from the new location, but
+existing ir_model_data rows still record the old module name. This script
+rewrites them.
+
+Special case: if the data-load phase of this very upgrade already created a
+new row in module='fusion_accounting_ai' with the same `name` as an old
+orphan (because the orphan lived under the old module name when data-load
+looked for it, missed it, and re-created the record), the UPDATE below would
+violate the unique constraint on (module, name). For those conflicts we
+delete the old orphan — the newly-created row is the one that records and
+the runtime will actually use going forward.
+
+Idempotent: running it a second time does nothing because the WHERE clauses
+find no matches.
