fix(configurator): wrap t-field widgets in <span> inside table cells

Acknowledgement PDF rendering failed with "QWeb widgets do not work
correctly on 'td' elements" — Odoo's qweb compiler rejects
t-field/t-options directly on <td>. Wrap the monetary / qty widgets
in an inner <span> for every cell that uses them (body rows + footer
total).

Caught during browser UAT on S00066 — shell _render_qweb_pdf smoke
test passed earlier because it bypasses the full compile path, but
the production /report/pdf/ endpoint fails the assertion.

+
+# 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).

+# 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`)

+
+---
+
+## 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_assets — Cursor / Claude Context
+
+## Purpose
+
+AI-augmented fixed asset management with depreciation schedules — a
+Fusion-native replacement for (and coexisting with) Odoo Enterprise's
+`account_asset` module. Ships in Phase 3 of the fusion_accounting roadmap.
+
+## Architecture
+
+Hybrid: the engine (`fusion.asset.engine`, AbstractModel) is the SINGLE
+write surface for the asset lifecycle. Everything else (controllers, OWL
+widget, AI tools, wizards, cron) routes through the engine's 7-method
+public API:
+
+- `compute_depreciation_schedule(asset, recompute=False)`
+- `post_depreciation_entry(asset, period_date=None)`
+- `dispose_asset(asset, sale_amount=0, sale_date=None, sale_partner=None, disposal_type='sale')`
+- `partial_sale(asset, sold_amount, sold_qty=None, sale_date=None, sale_partner=None)`
+- `pause_asset(asset, pause_date=None)`
+- `resume_asset(asset, resume_date=None)`
+- `reverse_disposal(asset)`
+
+Pure-Python services live in `services/`:
+
+- `depreciation_methods` — straight_line, declining_balance, units_of_production
+- `prorate` — first/last-period prorating: full_month, days_365, days_period
+- `salvage_value` — % of cost, fixed amount, zero
+- `anomaly_detection` — variance vs expected schedule, low utilization
+- `useful_life_predictor` + `useful_life_prompt` — LLM-suggested useful life with templated fallback
+
+Persisted models in `models/`:
+
+- `fusion.asset` — main model, state machine: draft → running → paused → disposed
+- `fusion.asset.depreciation.line` — board lines
+- `fusion.asset.category` — templates
+- `fusion.asset.disposal` — disposal records
+- `fusion.asset.anomaly` — flagged variances
+- `fusion.asset.book.values.mv` — pre-aggregated materialized view
+- `fusion.asset.engine` — AbstractModel (the API)
+- `fusion.assets.cron` — cron handlers (post depreciations, MV refresh, anomaly scan)
+- `account.move.line` (inherits) — adds `fusion_asset_id` linkage
+- `fusion.migration.wizard` (inherits in `models/`) — adds asset backfill step
+
+Wizards (TransientModel) in `wizards/`:
+
+- `fusion.create.asset.wizard` — assisted creation with AI useful-life suggestion
+- `fusion.disposal.wizard` — full disposal flow
+- `fusion.partial.sale.wizard` — partial-quantity disposal
+- `fusion.depreciation.run.wizard` — period close runner
+
+Controller: `controllers/assets_controller.py` exposes 8 JSON-RPC
+endpoints under `/fusion/assets/*` (list, get_detail, compute_schedule,
+post_depreciation, dispose, get_anomalies, suggest_useful_life,
+get_partner_history). All calls route through the engine.
+
+OWL frontend: `static/src/`
+
+- `services/assets_service.js` — central reactive state + RPC wrappers
+- `views/asset_dashboard/*` — top-level dashboard view
+- `components/asset_card`, `asset_detail_panel`, `depreciation_board`,
+  `disposal_dialog`, `ai_useful_life_panel`, `anomaly_strip` — 6 components
+- `scss/_variables.scss` + `assets.scss` + `dark_mode.scss`
+- `tours/assets_tours.js` — 5 OWL tour smoke tests
+
+## Coexistence
+
+When `account_asset` is installed the Asset Management menu hides via
+`fusion_accounting_core.group_fusion_show_when_enterprise_absent` (a
+computed group). The engine + AI tools remain available for the chat.
+The migration wizard backfills `fusion.asset` from existing
+`account.asset` records (verified live: 2 records, Task 35).
+
+## 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`).
+- **Materialized view refresh:** `fusion.asset.book.values.mv` is
+  refreshed by cron (REFRESH CONCURRENTLY in an autocommit cursor since
+  it can't run inside a regular Odoo transaction).
+- **Provider routing:** AI features look up
+  `fusion_accounting.provider.asset_useful_life`, falling back to
+  `fusion_accounting.provider.default`. When neither is set the
+  templated keyword fallback in `useful_life_predictor` keeps the
+  feature usable offline.
+
+## Performance baseline (Tasks 23 + 41)
+
+| Operation                          | P95   | Budget   | Headroom |
+|------------------------------------|-------|----------|----------|
+| `engine.compute_schedule` (10yr SL)| 1ms   | 500ms    | 500x     |
+| `engine.post_depreciation_entry`   | <1ms  | 300ms    | huge     |
+| `engine.dispose_asset`             | 5ms   | 300ms    | 60x      |
+| `controller.list` (35 assets)      | 42ms  | 300ms    | 7x       |
+| `controller.get_detail`            | 40ms  | 500ms    | 12x      |
+
+All Phase 3 perf metrics are within 1x of budget; no optimization was
+needed at ship (Task 42 skipped per the conditional rule).
+
+## Test counts (Phase 3 ship)
+
+- 140 logical tests total in fusion_accounting_assets
+- 0 failures, 0 errors
+- Coverage includes: 4 engine benchmarks + 1 controller benchmark
+  (tagged `benchmark`), 1 local LLM smoke (tagged `local_llm`, skips
+  when no LLM), 5 OWL tour tests (tagged `tour`, skip without
+  websocket-client), Hypothesis property tests on the engine,
+  integration tests on the public API, controller round-trip tests, MV
+  shape tests.
+
+## Known concerns / Phase 3.5 backlog
+
+- Sub-annual depreciation frequency (currently annual only)
+- Units-of-production assumes even per-period units
+- Disposal journal entry not yet created — `dispose_asset` writes the
+  `fusion.asset.disposal` record but not the cash / gain-loss move
+- Multi-currency, allocation rules, and analytic tags for depreciation
+  moves are out of scope for Phase 3
+- Partial-sale child asset is created with no own depreciation schedule
+  pre-disposal
+- Migration wizard inheritance lives in `models/` rather than
+  `wizards/` (small inconsistency with the rest of the wizard layout —
+  intentional to keep ORM ordering simple)
+- `useful_life_predictor` always returns a usable dict (templated
+  fallback when LLM absent), so callers can't distinguish "AI said so"
+  from "fallback fired"; the `confidence` key is the only signal

+
+AI-augmented fixed asset management for Odoo 19 Community — a
+Fusion-native replacement for Enterprise's `account_asset` module.
+
+## What it does
+
+- Three depreciation methods: straight-line, declining balance, and
+  units-of-production
+- Asset lifecycle state machine: draft → running → paused → disposed
+- Editable depreciation board with full schedule recompute
+- Disposal flow (sale, scrap, donation) plus partial-sale wizard
+- Daily cron for posting periodic depreciation
+- AI augmentation:
+  - **Anomaly detection** — variance vs expected schedule, low utilization
+  - **Useful-life suggestion** — LLM-driven from invoice context, with a
+    keyword-based templated fallback so the feature still works offline
+- Coexists with Enterprise `account_asset` (Enterprise wins by default;
+  the Fusion menu only appears when Enterprise is uninstalled)
+- Migration-aware: bootstrap step backfills `fusion.asset` from existing
+  `account.asset` rows so the AI has memory from day 1
+
+## Quick start
+
+```bash
+# Install
+odoo --addons-path=... -i fusion_accounting_assets
+
+# Open the dashboard (when Enterprise's account_asset is NOT installed)
+# Apps -> Asset Management -> Assets
+
+# 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.openai_api_key` = `lm-studio` (anything non-empty)
+  - `fusion_accounting.provider.asset_useful_life` = `openai`
+
+## Public API (engine)
+
+`fusion.asset.engine` is the single write surface. See `CLAUDE.md` for
+the full 7-method signature list.
+

+# fusion_accounting_assets — Upgrade Notes
+
+## Odoo Version Anchor
+
+This module targets **Odoo 19.0** (community-base).
+
+Reference snapshot of Enterprise code mirrored from:
+- `account_asset` (Odoo 19.0.x)
+- Source: `/Users/gurpreet/Github/RePackaged-Odoo/accounting/account_asset/`
+
+## 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.asset` / `account.move.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` (every persisted model)
+- `@api.depends('id')` → removed (none introduced)
+- `@route(type='json')` → `type='jsonrpc'` (all 8 endpoints in
+  `controllers/assets_controller.py`)
+- `numbercall` removed from `ir.cron` (data/cron.xml)
+- `res.groups.users` → `user_ids` and `ir.ui.menu.groups_id` →
+  `group_ids` (security + menu_views.xml)
+
+## Phase 3 → Phase 3.5 Migration
+
+If we ship Phase 3.5 (sub-annual depreciation frequency, disposal journal
+entries, multi-currency, allocation rules), changes will go in
+incremental commits. No DB migration needed (Phase 3 schema is
+forward-compatible — new columns will be nullable / default-valued).
+
+## Coexistence with Enterprise `account_asset`
+
+The migration step in `fusion.migration.wizard` backfills `fusion.asset`
+records from existing `account.asset` rows. It is idempotent (skips rows
+already linked via the `legacy_account_asset_id` column). Verified live
+on westin-v19: 2 records migrated cleanly.
+
+When `account_asset` is installed the Asset Management menu hides via
+`fusion_accounting_core.group_fusion_show_when_enterprise_absent`. The
+engine and AI tools remain available for chat-driven workflows.
