+# 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).

+## Coexistence
+
+Same pattern as Phase 1: `group_fusion_show_when_enterprise_absent` from `fusion_accounting_core`. Reports menu only visible when `account_reports` is NOT installed. Engine + AI tools always available.
+
+## Tasks (46 total)
+
+### Group 1: Foundation (tasks 1-2)
+1. Safety net (tag pre-phase-2, branch phase-2-reports) — **DONE**
+2. Plan doc + module skeleton
+
+### Group 2: Engine primitives — TDD layered (tasks 3-8)
+3. `services/date_periods.py` (fiscal periods, comparison derivation)
+4. `services/currency_conversion.py` + `services/account_hierarchy.py` + `services/totaling.py`
+5. `models/fusion_report.py` (report definition model)
+6. `services/line_resolver.py` (compute report rows from definition)
+7. `services/drill_down_resolver.py`
+8. `models/fusion_report_engine.py` (5-method API: compute_pnl, compute_balance_sheet, compute_trial_balance, compute_gl, drill_down)
+
+### Group 3: Per-report models (tasks 9-12)
+9. P&L (income statement)
+10. Balance sheet
+11. Trial balance
+12. General ledger
+
+### Group 4: AI features (tasks 13-17)
+13. Anomaly detection service (variance vs prior period)
+14. AI commentary service
+15. Commentary prompt + LLMProvider integration
+16. `fusion.report.commentary` persisted model
+17. `fusion.report.anomaly` persisted model
+
+### Group 5: Backend wiring (tasks 18-20)
+18. JSON-RPC controller (8 endpoints)
+19. ReportsAdapter `_via_fusion` paths
+20. 5 new AI tools
+
+### Group 6: Tests + perf (tasks 21-25)
+21. Property-based tests (totals balance invariant)
+22. Integration tests — P&L correctness vs known fixtures
+23. Integration tests — balance sheet + trial balance
+24. Materialized view for GL
+25. Cron jobs (anomaly scan + commentary refresh)
+
+### Group 7: Frontend (tasks 26-33)
+26. SCSS tokens + main report stylesheet
+27. `reports_service.js`
+28. `report_viewer` component (top-level)
+29. `report_table` component (rows, totals, drill chevrons)
+30. `drill_down_dialog`
+31. `period_filter` (date range + comparison toggle)
+32. `ai_commentary_panel` (Fusion-only)
+33. `anomaly_strip` (Fusion-only)
+
+### Group 8: Export + wizards (tasks 34-36)
+34. PDF export (QWeb template per report)
+35. XLSX export wizard
+36. Period selection + comparison wizard
+
+### Group 9: Migration + coexistence (tasks 37-39)
+37. Migration wizard inheritance (cache existing definitions)
+38. Menu + window actions with coexistence group filter
+39. Coexistence test
+
+### Group 10: Final tests + polish (tasks 40-46)
+40. 5 OWL tour tests
+41. Performance benchmarks
+42. Optimize if benchmarks fail (conditional)
+43. Local LLM compat test for commentary
+44. Update meta-module manifest
+45. CLAUDE.md, UPGRADE_NOTES.md, README.md
+46. End-to-end smoke + tag phase-2-complete + push
+
+## Performance Targets (P95)
+
+- `engine.compute_pnl` (1 year, 500 accounts): <2s
+- `engine.compute_balance_sheet`: <2s
+- `engine.compute_trial_balance`: <1s
+- `engine.compute_gl` (1 month, all accounts): <3s
+- `engine.drill_down` (1 line): <500ms
+- Controller `run` endpoint: <2.5s
+
+## V19 Conventions (from Phase 1 lessons)
+
+- `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`
+- `res.users.all_group_ids` for searches
+- `models.Constraint` for unique-keys
+- Prefer `env.flush_all()` before MV REFRESH
+
+## 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 1 final: 157 tests passing. Phase 2 target: ~120-150 additional.

+# Fusion IoT — Claude Code Instructions
+
+## Purpose
+
+Fusion IoT lets Fusion Apps products ingest live sensor readings from
+hardware mounted on a shop floor — initially tank temperature probes
+for Fusion Plating, with room to grow into label printers, scales,
+and any other device Odoo's IoT framework supports.
+
+## Folder contents
+
+```
+fusion_iot/
+├── iot_base/             # Repackaged from Odoo S.A. — shared JS utils
+├── iot/                  # Repackaged from Odoo S.A. — IoT Box mgmt models + UI
+└── fusion_plating_iot/   # Our wrapper — sensor→tank mapping + out-of-spec holds
+```
+
+## Repackaging notes — `iot_base` + `iot`
+
+Both copied as-is from `/Users/gurpreet/Github/RePackaged-Odoo/_dependencies/`
+(tag Odoo 19). Both are already LGPL-3 upstream — no license flip needed.
+
+**Gutted phone-home**:
+
+| File | Change |
+|------|--------|
+| `iot/models/update.py` | `Publisher_WarrantyContract._get_message` override REMOVED (no more IoT-Box counting-back to Odoo S.A. for enterprise licensing) |
+| `iot/iot_handlers/lib/load_worldline_library.sh` | DELETED (proprietary Worldline payment lib fetch from download.odoo.com — we don't use Worldline) |
+
+**Left intact** (NOT phone-home, don't remove):
+
+- `ir_config_parameter.py` — broadcasts `web.base.url` changes to paired IoT boxes via the internal IoT channel (not the internet)
+- `iot_box.py.version_commit_url` — cosmetic link to odoo/odoo on GitHub
+- `controllers/main.py` — serves the iot handlers zip to the Pi (this is the point of the module)
+
+## `fusion_plating_iot` — the wrapper
+
+### Models
+
+**`fp.tank.sensor`** — maps a physical sensor to a tank + parameter
+- `device_serial` — hardware unique ID (e.g. DS18B20 1-Wire address)
+- `iot_device_id` — optional link to `iot.device` if the sensor comes in via Pi proxy
+- `tank_id` / `bath_id` — where the sensor lives
+- `parameter_id` — what bath parameter it reports (temperature, pH, etc.)
+- `alert_min_override` / `alert_max_override` — per-sensor spec override; else inherits from `fusion.plating.bath.parameter.target_min/max`
+- Cached `last_reading_value` / `last_reading_at` / `last_reading_in_spec` for fast list views
+
+**`fp.tank.reading`** — time-series log of every reading
+- Append-only — never updated/deleted. The compliance record of bath history.
+- `create()` evaluates each reading against the sensor's alert range
+- Raises a `fusion.plating.quality.hold` ONCE on the transition from in-spec → out-of-spec (no spam)
+
+**`fusion.plating.tank`** — extended with `x_fc_sensor_ids` o2m + `x_fc_has_out_of_spec` bool for the tank form.
+
+### Endpoint — `POST /fp/iot/ingest`
+
+For sensors that skip the Pi proxy and POST directly over HTTP.
+
+- Auth: `X-FP-IOT-Token` header OR `"token"` key in JSON body, compared to `ir.config_parameter[fusion_plating_iot.ingest_token]` using `hmac.compare_digest`
+- Seeded token value: `CHANGE-ME-AFTER-INSTALL` — **MUST be rotated immediately after install** via Settings → Technical → System Parameters
+- Payload: single `{device_serial, value, read_at}` OR batch `{readings: [...]}`
+- Response: 200 + `{ok: true, accepted: N}`, 401 on auth fail, 404 if device_serial unknown
+
+### Dependencies
+
+- `iot` — the server-side Odoo IoT module (in this same folder, needs to be installed first)
+- `fusion_plating` — for `fusion.plating.tank` + `fusion.plating.bath.parameter`
+- `fusion_plating_quality` — for `fusion.plating.quality.hold`
+
+### Not yet — Phase B (when Pi hardware arrives)
+
+- DS18B20 handler module for `iot_drivers` (the Pi-side proxy)
+- Systemd service config for running `iot_drivers` on vanilla Raspberry Pi OS
+- Pi firmware README

+Fusion Plating — IoT Integration
+================================
+
+Bridges the generic `iot` module (IoT Box + device management) to
+plating-specific models:
+
+* ``fp.tank.sensor`` — maps an ``iot.device`` to a
+  ``fusion.plating.tank`` (or a ``fusion.plating.bath``).
+* ``fp.tank.reading`` — time-series log of every sensor reading.
+* Auto-creates a ``fusion.plating.quality.hold`` when a reading
+  falls outside the tank/bath's target range (per
+  ``fusion.plating.bath.parameter`` spec).
+
+Supports both the Odoo-IoT proxy path (Pi running iot_drivers) AND
+a direct HTTP ingest path (``/fp/iot/ingest``) for sensors that
+skip the proxy and POST straight to Odoo with a shared secret.

+# No other functional changes — the module still runs Odoo's IoT pairing,
