 ## What Comes After Phase 0
 
 Phase 1 — Bank Reconciliation. Brainstorm in a new session, produce its own design doc and implementation plan. The Phase 0 BankRecAdapter `_via_fusion` path becomes meaningful when Phase 1 ships `fusion.bank.rec.widget`.

+## Phase 0 Smoke Test Results — 2026-04-18
+
+Host: `odoo-westin` (container `odoo-dev-app`, DB `westin-v19`, Odoo 19, Enterprise installed alongside).
+
+### Deploy
+- Clean redeploy: removed and re-copied all four modules (`fusion_accounting`, `fusion_accounting_core`, `fusion_accounting_ai`, `fusion_accounting_migration`) into `/mnt/extra-addons/` on the container.
+- Meta-module upgrade (`odoo -u fusion_accounting --stop-after-init --no-http`): exit 0, all four modules `installed` in `ir_module_module`. Only pre-existing unrelated warnings (studio, fusion_claims label collisions, docutils, `_sql_constraints` deprecations on third-party modules).
+
+### Test suite results
+- Command: `odoo --test-tags post_install --stop-after-init --no-http -u fusion_accounting_core,fusion_accounting_ai,fusion_accounting_migration`
+- Exit code: **0**
+- Per-test `Starting …` lines observed (odoo.tests INFO handler): **23 tests**
+  - `fusion_accounting_core` — 7 tests: `TestEnterpriseDetection` ×2, `TestSharedFieldOwnership` ×5
+  - `fusion_accounting_ai` — 14 tests: `TestDataAdapterBase` ×2, `TestBankRecAdapter` ×1, `TestReportsAdapter` ×4, `TestFollowupAdapter` ×4, `TestAssetsAdapter` ×1, `TestPostMigration` ×2
+  - `fusion_accounting_migration` — 2 tests: `TestSafetyGuard` ×2
+- Result: **23 PASS, 0 FAIL, 0 ERROR, 0 SKIP**
+- No `AssertionError` / `Traceback` / `FAILED` lines in the log.
+- Odoo's `odoo.tests.stats` reports slightly higher per-module counts (ai: 26, core: 11, migration: 4) because Odoo also counts its own implicit per-module sanity checks (XML validation, etc.) beyond our explicit `TestCase` methods; all non-explicit tests also passed since exit code is 0 and no failure lines appear.
+
+### Verification spot-checks
+- **Migration wizard menu (6a)**: present — `ir_ui_menu` contains both `Fusion Accounting` (id 2802, root) and `Migrate from Enterprise` (id 2803, child of 2802). Ten total fusion menus registered across `fusion_accounting_ai` (8) and `fusion_accounting_migration` (2).
+- **AI module actions (6b)**: 8 actions registered under `module='fusion_accounting_ai'` — `action_fusion_session`, `action_fusion_history`, `action_fusion_rule`, `action_fusion_dashboard`, `action_vendor_tax_profiles`, `action_recurring_patterns`, `action_fusion_rule_wizard`, `action_report_fusion_audit`.
+- **Security groups (6c)**: three groups present in `fusion_accounting_core` — `Administrator`, `Manager`, `User`, each with `0` users (expected for a fresh install with no user assignments yet).
+- **Shared-field columns on `account_move` (6d)**:
+  - `signing_user` (integer, FK to `res_users`) — physically present, owned by `fusion_accounting_core` ✓
+  - `payment_state_before_switch` (character varying) — physically present, owned by `fusion_accounting_core` ✓
+  - `deferred_move_ids` / `deferred_original_move_ids` — both present via m2m relation table `account_move_deferred_rel` with columns `original_move_id` / `deferred_move_id` (matches Enterprise's table name; test `test_deferred_relation_table_name_matches_enterprise` passes) ✓
+  - `deferred_entry_type` — exists in the ORM (`ir_model_fields.store='f'`) but no local column, because Enterprise's `account_asset` (installed on this DB: `account_accountant`, `account_asset`, `account_reports` all `installed`) currently owns the physical storage. This is the intended dual-ownership design from Task 17 — fusion_accounting_core declares a stub so the field survives Enterprise uninstall; the `TestSharedFieldOwnership.test_account_move_deferred_fields_exist` test passed and confirmed the field is in `Move._fields`.
+
+### Deferred
+- **Task 18** (empirical Enterprise-uninstall verification test): deferred pending environment provisioning decision. Requires a dedicated scratch DB where we can actually uninstall Enterprise without disturbing the productive westin-v19 tenant. Tracked in `fusion_accounting/docs/superpowers/plans/2026-04-18-ci-deferred.md` (or equivalent follow-up note). The shared-field design is validated in principle by Tasks 17+21 and the `TestSharedFieldOwnership` suite; Task 18 adds the "actually uninstall, confirm nothing collapses" live check.
+
+### Phase 0 Status: **COMPLETE** (pending Task 18 empirical test)
+
+Ready to proceed to Phase 1 (Bank Reconciliation) — brainstorming session + its own design doc + implementation plan.
