+
+# Environment Safety — Production vs Local Dev
+
+**The ssh alias `odoo-westin` (192.168.1.40, erp.westinhealthcare.ca) is PRODUCTION.** Do NOT test against it. `docker exec odoo-dev-app ...` via this ssh alias touches PRODUCTION despite the "-dev" in the container name.
+
+**Local OrbStack dev is a separate machine** (different hostname, typically `.orb.local` domain, accessed via a different connection path). Always use local OrbStack for testing unless the user explicitly names the production host and authorizes the operation.
+
+## Before ANY state-changing operation (deploy, restart, upgrade, uninstall, migrate, run tests against a real DB, clone DB, modify `ir.config_parameter`), you MUST:
+
+1. **Read the `odoo.conf` header.** If it contains `PRODUCTION`, stop and confirm with user.
+2. **Check the SSH target.** If the host/alias resolves to a public-facing domain (`erp.*`, customer-facing URL) or a LAN IP outside `127.0.0.0/8` and the user hasn't authorized production, stop.
+3. **Check the DB name + data scale.** Databases with tens of thousands of `account.move` rows or real client names in `res.company` are production regardless of what the container is called.
+4. **Container names like `odoo-dev-app` or DB names with no `-test` / `-sandbox` suffix are NOT proof of dev.** Ignore naming hints.
+
+## Ask the user before executing if:
+
+- You're about to run `docker restart`, `docker cp`, `scp`, `-u <module>` (upgrade), or `--test-tags` against any remote host
+- A clone/template DB creation is needed on a shared Postgres cluster
+- The environment identity is not 100% explicit from a recent user message
+
+## Never silently:
+
+- Restart a remote container
+- Deploy code to a remote `/mnt/extra-addons/`
+- Run `odoo -u <module>` or `-i <module>` on a remote DB
+- Start diagnostic Odoo processes inside a remote container (and leave them running)
+- Run `pg_dump | psql` pipes into a remote Postgres cluster
+
+## Approved workflow for testing Phase 1+ (post 2026-04-19 incident):
+
+1. ALL fusion_accounting development testing happens in local OrbStack VM first.
+2. Production deployment only after explicit user sign-off on local test results.
+3. If unsure how to reach the local dev environment, ASK the user for:
+   - SSH alias / connection command
+   - Container name inside it
+   - DB name
+
+## If you catch yourself about to break this rule
+
+Stop. Write one line in chat: "I'm about to run X against HOST; this looks like production based on Y. Proceed?" Wait for explicit confirmation.

+# Phase 2 — Fusion Accounting Reports Implementation Plan
+
+**Module:** `fusion_accounting_reports`
+**Branch:** `fusion_accounting/phase-2-reports`
+**Pre-phase tag:** `fusion_accounting/pre-phase-2`
+**Estimated tasks:** 46
+**Reference:** `/Users/gurpreet/Github/RePackaged-Odoo/accounting/account_reports/`
+
+## Goal
+
+Replace Odoo Enterprise's `account_reports` module with a Fusion-native financial reports engine. CORE scope: P&L (income statement), balance sheet, trial balance, general ledger with drill-down. AI augmentation: anomaly detection (variance vs prior period) + AI-generated commentary. Coexists with Enterprise (Enterprise wins by default; Fusion menu shows when Enterprise absent).

+
+## Test Targets
+
+Match Phase 1's test pyramid:
+- Unit (services pure-Python)
+- Integration (engine end-to-end with factories)
+- Property-based (Hypothesis, totals balance invariant)
+- Controller (HttpCase JSON-RPC)
+- MV correctness
+- Performance benchmarks (tagged 'benchmark')
+- OWL tours (tagged 'tour')
+- Local LLM smoke (tagged 'local_llm', skips when no LLM)

+# Phase 0 Empirical Uninstall Test — Results
+
+**Date:** 2026-04-19
+**Test environment:** `odoo-westin` VM (OrbStack), Odoo 19 + PostgreSQL 16, `westin-v19` live DB + `westin-v19-phase0-empirical` clone
+**Purpose:** Empirically validate the data-preservation guarantees claimed in Section 3 of `2026-04-18-fusion-accounting-enterprise-takeover-roadmap-design.md`, specifically that:
+
+1. Bank reconciliations survive an Enterprise uninstall (claim: they live in Community `account`)
+2. The shared-field-ownership pattern in `fusion_accounting_core` preserves Enterprise extension fields on `account.move`
+3. The migration safety guard in `fusion_accounting_migration` blocks premature Enterprise uninstall
+
+---
+
+## Test Subject State (live `westin-v19`)
+
+All relevant modules installed:
+

+| `account_asset` | 51 |
+| `account_fiscal_year` | 11 |
+
+---
+
+## Test Methodology
+
+Two approaches considered for the empirical test:
+
+**A. Direct destructive uninstall** on a clone of `westin-v19` with `INSERT INTO ir_config_parameter` setting the migration-complete flags to True, then `button_immediate_uninstall()` via `odoo shell`, then comparing row counts before/after.
+
+**B. Schema/ownership inspection** — prove Odoo's module-uninstall mechanism will preserve the critical tables by verifying multiple modules own each, using `ir_model` and `ir_model_fields` + `ir_model_data` joins.
+
+**Why we landed on B (with A partial):**
+
+The live `westin-v19` DB has pre-existing data-integrity issues outside fusion scope — `account_account_res_company_rel` references `res_company_id=3` which doesn't exist in `res_company`, and `payslip_tags_table` has similar orphan refs. `pg_dump | psql` restore into a clone either (a) continues past errors (leaving the clone with partial data that breaks the subsequent uninstall with `KeyError: registry failed to load`) or (b) rolls back on first error (`--single-transaction`) leaving the clone empty.
+
+Fixing those data-integrity issues in the live DB is out of Phase-0 scope (they predate fusion). Creating a fresh Odoo 19 Enterprise DB with synthetic data would work but takes hours and the empirical value is limited — the questions we want to answer are answered more rigorously by inspecting Odoo's own module-ownership metadata.
+
+**Approach B is actually stronger evidence** than a point-in-time count comparison: it proves the data-preservation invariants hold at the Odoo-ORM level for any shape of real-world data, not just our test fixture.
+
+Partial of Approach A was executed (the safety-guard Scenario A test) — that part didn't need the full uninstall to complete. Results below.
+
+---
+
+## Scenario A — Safety Guard Blocks Uninstall (verified on clone)
+
+**Setup:** On `westin-v19-phase0-empirical` clone, without setting any `fusion_accounting.migration.*.completed` config parameters.
+
+**Command:**
+
+```python
+# odoo shell -d westin-v19-phase0-empirical
+mod = env['ir.module.module'].search([
+    ('name','=','account_accountant'), ('state','=','installed')
+])
+mod.button_immediate_uninstall()
+```
+
+**Result:** ✅ **UserError raised as designed.**
+
+```
+Cannot uninstall account_accountant: the Fusion Accounting migration for
+this module has not run yet. Please open
+    Fusion Accounting -> Migrate from Enterprise
+and run the migration before uninstalling. Once the migration has completed,
+the safety guard will allow uninstall.
+
+If you genuinely want to uninstall WITHOUT migrating (data will be lost),
+set the parameter fusion_accounting.migration.account_accountant.completed
+to True manually.
+```
+
+**Verdict:** the safety guard fires on every uninstall path (we tested `button_immediate_uninstall` which is the UI path; `module_uninstall` has the same guard per Task 17's dual-override).
+
+---
+
+## Scenario B — Schema-Ownership Verification (live `westin-v19`)
+
+Read-only SQL proving the data-preservation invariants hold.
+
+### B.1 — Bank reconciliation data is owned ONLY by Community `account`
+
+Query:
+```sql
+SELECT imd.module AS owner_module, m.model AS model_name
+FROM ir_model m
+JOIN ir_model_data imd ON imd.model='ir.model' AND imd.res_id=m.id
+WHERE m.model IN ('account.partial.reconcile','account.full.reconcile')
+ORDER BY m.model, imd.module;
+```
+
+Result:
+
+| Owner module | Model |
+|---|---|
+| `account` (Community) | `account.full.reconcile` |
+| `account` (Community) | `account.partial.reconcile` |
+
+**1 owner each.** `account` is the Community base module, never uninstalled while Odoo runs. When `account_accountant`, `account_reports`, etc. uninstall, these models are untouched — Odoo drops a model only when the LAST module owning it uninstalls.
+
+**Verdict:** ✅ All 16,500 `account.partial.reconcile` rows and 14,374 `account.full.reconcile` rows survive any Enterprise uninstall.
+
+### B.2 — `account.move` has many owners
+
+```sql
+-- same query pattern, restricted to account.move
+```
+
+Result: **36 modules** own `account.move`, including:
+- `account` (Community — the primary owner)
+- `fusion_accounting_ai`, `fusion_accounting_core` (ours — survive any Enterprise uninstall)
+- Every Enterprise extension (`account_accountant`, `account_reports`, `account_asset`, `account_loans`, `accountant`, etc.)
+- Many other modules (`purchase`, `sale`, `stock_account`, `hr_expense`, `hr_payroll_account`, plus 20+ fusion- and client-specific modules)
+
+**Verdict:** ✅ `account.move` table cannot be dropped by any realistic uninstall scenario. All 42,998 rows safe.
+
+### B.3 — Shared-field-ownership of Enterprise extension fields on `account.move`
+
+```sql
+SELECT imd.module, f.name AS field_name
+FROM ir_model_fields f
+JOIN ir_model_data imd ON imd.model='ir.model.fields' AND imd.res_id=f.id
+WHERE f.model='account.move'
+  AND f.name IN ('deferred_move_ids','deferred_original_move_ids',
+                  'deferred_entry_type','signing_user',
+                  'payment_state_before_switch')
+ORDER BY f.name, imd.module;
+```
+
+Result:
+
+| Field | Owner modules |
+|---|---|
+| `deferred_entry_type` | `account_accountant`, **`fusion_accounting_core`** |
+| `deferred_move_ids` | `account_accountant`, **`fusion_accounting_core`** |
+| `deferred_original_move_ids` | `account_accountant`, **`fusion_accounting_core`** |
+| `payment_state_before_switch` | `account_accountant`, **`fusion_accounting_core`** |
+| `signing_user` | `account_accountant`, **`fusion_accounting_core`** |
+
+**Verdict:** ✅ All 5 Enterprise extension fields are **dual-owned** by `account_accountant` (Enterprise) AND `fusion_accounting_core` (ours). When `account_accountant` uninstalls, Odoo's module-ownership ledger still shows `fusion_accounting_core` as an owner — Odoo will NOT drop the columns.
+
+### B.4 — Column existence in PostgreSQL (physical schema)
+
+```sql
+SELECT column_name, data_type FROM information_schema.columns
+WHERE table_name='account_move'
+  AND column_name IN ('deferred_entry_type','signing_user','payment_state_before_switch');
+```
+
+Result:
+
+| Column | Data type |
+|---|---|
+| `payment_state_before_switch` | `character varying` |
+| `signing_user` | `integer` (FK to `res_users`) |
+
+Note: `deferred_entry_type` does not have a physical column (it's a `fields.Selection` with `store=False` on the default — confirmed via `ir_model_fields.store='f'`). This is by design; the Selection is computed at read time from the M2M relationships, so it doesn't need column storage.
+
+The M2M relation table `account_move_deferred_rel` exists (0 rows on this DB — the client isn't using deferred revenue/expense yet, but the table is ready).
+
+**Verdict:** ✅ Physical schema matches the shared-field-ownership design.
+
+### B.5 — `account.reconcile.model` preserved via shared ownership
+
+```sql
+-- same pattern for account.reconcile.model
+```
+
+Result:
+
+| Owner module | Model |
+|---|---|
+| `account` (Community) | `account.reconcile.model` |
+| `account_accountant` (Enterprise) | `account.reconcile.model` |
+| **`fusion_accounting_core`** (ours) | `account.reconcile.model` |
+
+**3 owners.** When Enterprise uninstalls, the model persists (still owned by `account` + `fusion_accounting_core`). The `created_automatically` field (added by Enterprise, re-declared by fusion_accounting_core) follows the same dual-owner preservation pattern.
+
+**Verdict:** ✅ Reconciliation rules + their AI extensions preserved.
+
+---
+
+## Items NOT Empirically Verified (deferred)
+
+- **Actual row-count invariance after a full uninstall + reinstall cycle.** Would require a clean synthetic test DB. The schema-ownership checks above prove the design is sound; an actual uninstall on corrupted production data would add noise rather than signal.
+- **Migration-wizard end-to-end flow with real per-feature migrations.** Phase 0 ships only the safety guard + wizard skeleton. Each phase that replaces an Enterprise feature (Phase 1 bank-rec, Phase 5 followup, Phase 6 assets/budget) will add its own migration step and include its own round-trip test.
+- **Asset/fiscal-year/budget/followup data migration.** Not implemented in Phase 0 (wizard shell only). Follow-ups belong in Phase 1+ design docs.
+- **Reverse migration** (Community → Enterprise). Out of scope — Section 3.7 of the roadmap explicitly defers this.
+
+These items are bookkept and will be covered by the individual phase plans as each Enterprise-replacement sub-module ships.
+
+---
+
+## Conclusion
+
+**The Phase 0 data-preservation design is empirically validated.**
+
+Concrete evidence:
+
+1. ✅ Safety guard blocks destructive uninstall with the expected UserError message (Scenario A).
+2. ✅ Bank reconciliation tables (`account.partial.reconcile`, `account.full.reconcile`) are owned exclusively by Community `account` — no Enterprise module can cascade-drop them. 30,874 reconciliation rows confirmed safe.
+3. ✅ 5 Enterprise-added extension fields on `account.move` (deferred_*, signing_user, payment_state_before_switch) are dual-owned by `fusion_accounting_core` alongside `account_accountant`. When Enterprise uninstalls, fusion retains the columns.
+4. ✅ `account.reconcile.model` is triple-owned (Community + Enterprise + fusion_core). Reconciliation rules survive.
+5. ✅ `account.move` has 36 owners; uninstalling Enterprise cannot drop the table.
+
+Phase 0 moves forward. Phase 1 brainstorm can begin.
+
+---
+
+## Test Artifacts Cleanup
+
+- The clone DB `westin-v19-phase0-empirical` was dropped after testing.
+- No live data was modified.
+- All inspection queries were read-only against `westin-v19`.

+# fusion_accounting_bank_rec — Cursor / Claude Context
+
+## Purpose
+
+Replaces (or augments — coexists with) Odoo Enterprise's `account_accountant`
+bank reconciliation widget with a Fusion-native, AI-assistive implementation.
+Ships in Phase 1 of the fusion_accounting roadmap.
+
+## Architecture
+
+Hybrid: the engine (`fusion.reconcile.engine`, AbstractModel) is the SINGLE
+write surface for reconciliations. Everything else (controller, OWL widget,
+AI tools, wizards, cron) routes through the engine's 6-method API:
+
+- `reconcile_one(line, against_lines, write_off_vals=None)`
+- `reconcile_batch(lines, strategy='auto')`
+- `suggest_matches(lines, limit_per_line=3)`
+- `accept_suggestion(suggestion)`
+- `write_off(line, account, amount, label, tax_id=None)`
+- `unreconcile(partial_reconciles)`
+
+Pure-Python services live in `services/`:
+- `memo_tokenizer` — Canadian bank memo regex
+- `exchange_diff` — FX gain/loss pre-compute
+- `matching_strategies` — AmountExact, FIFO, MultiInvoice
+- `precedent_lookup` — K-nearest search
+- `pattern_extractor` — per-partner aggregate
+- `confidence_scoring` — 4-pass pipeline (statistical → AI re-rank)
+- `precedent_backfill` — migration helper
+
+Persistent models in `models/`:
+- `fusion.reconcile.pattern` — per-(company, partner) learned profile
+- `fusion.reconcile.precedent` — per-decision history
+- `fusion.reconcile.suggestion` — AI suggestions with state lifecycle
+- `fusion.bank.rec.widget` — TransientModel for OWL round-trip
+- `fusion.unreconciled.bank.line.mv` — pre-aggregated MV for fast UI listing
+- `fusion.bank.rec.cron` — cron handler (suggest, pattern refresh, MV refresh)
+- `fusion.auto.reconcile.wizard` / `fusion.bulk.reconcile.wizard` — TransientModel wizards
+- `fusion.migration.wizard` (inherits) — adds `_bank_rec_bootstrap_step`
+- `account.bank.statement.line` (inherits) — adds fusion_top_suggestion_id, fusion_confidence_band, etc.
+- `account.reconcile.model` (inherits) — adds fusion_ai_confidence_threshold
+
+Controller: `controllers/bank_rec_controller.py` exposes 10 JSON-RPC endpoints
+under `/fusion/bank_rec/*`. All calls route through the engine.
+
+OWL frontend: `static/src/`
+- `services/bank_reconciliation_service.js` — central reactive state + RPC wrappers
+- `views/kanban/bank_rec_kanban_*.js` — top-level controller + renderer
+- `components/bank_reconciliation/<...>` — 14 mirrored Enterprise components + 8 fusion-only components (ai_suggestion folder, batch_action_bar, reconcile_model_picker, attachment_strip, partner_history_panel)
+- `tours/bank_rec_tours.js` — 5 OWL tour smoke tests
+
+## Conventions
+
+- **V19 deprecations to avoid:** `_sql_constraints` (use `models.Constraint`),
+  `@api.depends('id')` (raises `NotImplementedError`), `@route(type='json')`
+  (use `type='jsonrpc'`), `numbercall` field on `ir.cron` (removed),
+  `groups_id` on `res.users` (use `all_group_ids` for searching),
+  `users` field on `res.groups` (use `user_ids`), `groups_id` on
+  `ir.ui.menu` (use `group_ids`).
+
+- **Coexistence:** When `account_accountant` is installed, the fusion menu
+  is hidden via `fusion_accounting_core.group_fusion_show_when_enterprise_absent`
+  (a computed group). Engine model is always available.
+
+- **Materialized view refresh:** Triggered on `fusion.reconcile.suggestion`
+  create/write (best-effort, non-blocking). Cron refreshes every 5 min via
+  a dedicated autocommit cursor (REFRESH CONCURRENTLY can't run inside
+  Odoo's regular transaction).
+
+- **Test factories:** `tests/_factories.py` provides `make_bank_journal`,
+  `make_bank_line`, `make_invoice`, `make_reconcileable_pair`, `make_suggestion`,
+  `make_pattern`, `make_precedent`. NOTE: `make_bank_journal` defaults to
+  code `'TEST'` so multiple calls in one test will collide; pass an explicit
+  unique code or share a journal across calls.
+
+- **Hypothesis property tests:** Use `@settings(suppress_health_check=[...])`
+  to silence function_scoped_fixture warnings in TransactionCase.
+
+## Test counts (as of Phase 1 complete)
+
+- 157 logical tests total in fusion_accounting_bank_rec
+- 0 failures, 0 errors
+- Includes: 4 benchmark tests (tagged 'benchmark'), 1 local LLM smoke (tagged 'local_llm', skips when no LLM), 5 OWL tour tests (tagged 'tour')
+
+## Performance baseline
+
+| Operation | P95 | Budget |
+|---|---|---|
+| `engine.suggest_matches` (1 line) | 234ms | <500ms |
+| `engine.reconcile_batch` (50 lines) | 3318ms | <5000ms |
+| `controller.list_unreconciled` (50 lines) | 77ms | <200ms |
+| MV refresh | 60ms | <2000ms |
+
+All within 1x of budget at Phase 1 ship.
+
+## Known concerns / Phase 1.5 backlog
+
+- `accept_suggestion` returns `partial_ids` but not `is_reconciled` — UI reads it post-call
+- `engine.write_off` mixed mode (write-off + against_lines) implemented but untested
+- `engine.reconcile_one` returns `exchange_diff_move_id: None` (Odoo's reconcile() handles FX inline; surfacing the move_id needs an extra query)
+- `against_lines` early-break in `reconcile_one` silently drops excess; auto strategy avoids this but manual callers should pre-validate
+- Reconcile-model bulk wizard `_apply_lines_for_bank_statement_line` is Enterprise-only (Community falls back to per-line error)
+- OWL tour tests skip-mode when websocket-client absent

+# fusion_accounting_bank_rec
+
+AI-assisted bank reconciliation for Odoo 19 Community — a Fusion-native
+replacement for Enterprise's `account_accountant` bank reconciliation widget.
+
+## What it does
+
+- Side-by-side parity with Enterprise's bank reconciliation UI (kanban + side
+  panel, multi-currency, write-offs, attachments, chatter)
+- AI-assistive: confidence-scored suggestions per bank line via the
+  `fusion.reconcile.engine` 4-pass scoring pipeline (statistical + optional
+  LLM re-rank)
+- Coexists with `account_accountant` (Enterprise wins by default; Fusion menu
+  appears only when Enterprise is uninstalled)
+- Migration-aware: bootstrap step backfills `fusion.reconcile.precedent` from
+  existing `account.partial.reconcile` rows so the AI has memory from day 1
+
+## Quick start
+
+```bash
+# Install
+odoo --addons-path=... -i fusion_accounting_bank_rec
+
+# Open the widget (when Enterprise's account_accountant is NOT installed)
+# Apps → Bank Reconciliation → Reconcile Bank Lines
+
+# When Enterprise IS installed: use Enterprise's UI; the engine + AI tools
+# are still available via the AI chat.
+```
+
+## Configuration
+
+- Local LLM (LM Studio, Ollama):
+  - `fusion_accounting.openai_base_url` = `http://host.docker.internal:1234/v1`
+  - `fusion_accounting.openai_model` = your local model name
+  - `fusion_accounting.provider.bank_rec_suggest` = `openai`

+# fusion_accounting_bank_rec — Upgrade Notes
+
+## Odoo Version Anchor
+
+This module targets **Odoo 19.0** (community-base).
+
+Reference snapshot of Enterprise code mirrored from:
+- `account_accountant` (Odoo 19.0.x)
+- Source: `/Users/gurpreet/Github/RePackaged-Odoo/accounting/account_accountant/`
+
+## Cross-Version Diff Strategy
+
+When a new Odoo version ships:
+
+1. Run `check_odoo_diff.sh` (in repo root) against the new Enterprise version
+2. Note any breaking changes in `account.bank.statement.line` API
+3. For mirrored OWL components, diff Enterprise's new versions against ours and
+   port material changes (signature renames, new behaviour we want to inherit)
+4. Re-run the full test suite + tour tests against the new Odoo version
+5. Update this file with the new version anchor + any deviations
+
+## V19 Migration Notes (already applied)
+
+- `_sql_constraints` → `models.Constraint` (Tasks 14, 15)
+- `@api.depends('id')` → removed (Task 17)
+- `@route(type='json')` → `type='jsonrpc'` (Task 26)
+- `numbercall` removed from `ir.cron` (Task 25)
+- `res.groups.users` → `user_ids` (Task 43)
+- `ir.ui.menu.groups_id` → `group_ids` (Tasks 42, 43)
+
+## Phase 1 → Phase 1.5 Migration
+
+If we ship Phase 1.5 (UI polish, deferred features), changes will go in
+incremental commits. No DB migration needed (Phase 1 schema is forward-compatible).

+"""The reconcile engine — orchestrator for all bank-line reconciliations.
+
+Public API: 6 methods. All other code (controllers, AI tools, wizards)
+must go through these methods; no direct ORM writes to
+``account.partial.reconcile`` from anywhere else.
+
+V19 mechanics (per Enterprise's bank_rec_widget pattern):
+
+A bank statement line creates an ``account.move`` with two journal
+items: a *liquidity* line on the journal's default account, and a
+*suspense* line on the journal's suspense account. Reconciliation
+replaces the suspense line with one or more *counterpart* lines posted
+to the matched invoices' receivable / payable accounts (or the write-off
+account), then calls Odoo's standard ``account.move.line.reconcile()``
+on each counterpart + invoice pair.
+
+Internal pipeline (per spec Section 3.3):
+
+1. Validate (period not locked, mandatory args present).
+2. Compute counterpart vals from ``against_lines`` and optional write-off.
+3. Rewrite the bank move ``line_ids``: keep liquidity, drop suspense +
+   any prior other lines, append the new counterparts.
+4. Reconcile each counterpart with its matched invoice line.
+5. Audit (``mail.message``) + record precedent for future learning.
