+# Phase 3 — Fusion Accounting Assets Implementation Plan
+
+**Module:** `fusion_accounting_assets`
+**Branch:** `fusion_accounting/phase-3-assets`
+**Pre-phase tag:** `fusion_accounting/pre-phase-3`
+**Estimated tasks:** ~50
+**Reference:** `/Users/gurpreet/Github/RePackaged-Odoo/accounting/account_asset/` (~2258 LOC Python)
+
+## Goal
+
+Replace Odoo Enterprise's `account_asset` module — asset management with depreciation schedules, disposal, partial sale, and reporting. CORE scope: 3 depreciation methods (straight-line, declining balance, units of production), full asset lifecycle, depreciation board, disposal/sale wizards. AI augmentation: utilization anomaly detection + AI-suggested useful life from invoice context. Coexists with Enterprise.
+
+## Architecture (HYBRID engine, Phase 1+2 pattern)

+42. Optimize if benchmarks fail (conditional)
+43. Local LLM compat test for useful_life_predictor
+44. Update meta-module manifest
+45. CLAUDE.md, UPGRADE_NOTES.md, README.md
+46. End-to-end smoke + tag phase-3-complete + push

+
+## Performance Targets (P95)
+
+- `compute_schedule` (10-year asset): <500ms
+- `post_depreciation_entry`: <200ms
+- `dispose_asset`: <300ms
+- Controller `list`: <300ms
+- Controller `get_detail`: <500ms
+
+## V19 Conventions (carried from Phase 1+2)
+
+- `models.Constraint` not `_sql_constraints`
+- No `@api.depends('id')` on stored compute fields
+- `@route(type='jsonrpc')` not `type='json'`
+- `ir.cron` has no `numbercall` field
+- `res.groups.user_ids` not `users`
+- `ir.ui.menu.group_ids` not `groups_id`
+- `models.Constraint` for unique-keys
+- `env.flush_all()` before MV REFRESH
+- REFRESH MATERIALIZED VIEW CONCURRENTLY needs autocommit cursor
+
+## Test Targets
+
+Match Phase 1+2 test pyramid:
+- Unit (pure-Python services)
+- Integration (engine end-to-end)
+- Property-based (Hypothesis: schedule total invariants)
+- Controller (HttpCase JSON-RPC)
+- MV correctness
+- Performance benchmarks (tagged 'benchmark')
+- OWL tours (tagged 'tour')
+- Local LLM smoke (tagged 'local_llm')
+
+Phase 1+2 final: 287 tests. Phase 3 target: ~140-180 additional → ~430-470 total.

+# 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

+# fusion_accounting_assets
+
+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.
+
+## See also

+# 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.
