+# Phase 4 — Fusion Accounting Follow-up Implementation Plan
+
+**Module:** `fusion_accounting_followup`
+**Branch:** `fusion_accounting/phase-4-followup`
+**Pre-phase tag:** `fusion_accounting/pre-phase-4`
+**Estimated tasks:** ~35
+**Reference:** `/Users/gurpreet/Github/RePackaged-Odoo/accounting/account_followup/` (~1318 LOC Python)
+
+## Goal
+
+Replace Enterprise's `account_followup` module — multi-level dunning sequences for unpaid invoices, with AI augmentation: contextually-appropriate follow-up text generation + payment-risk scoring + tone adjustment based on customer history. Coexists with Enterprise.
+
+## Architecture (HYBRID engine, Phases 1-3 pattern)

+- `send_followup_email` (no LLM): <200ms
+- `generate_text` (with LLM): <5s
+- Controller `list_overdue` (50 partners): <500ms
+
+## V19 Conventions (Phases 1-3 lessons)
+
+- `models.Constraint` not `_sql_constraints`
+- No `@api.depends('id')` on stored compute fields
+- `@route(type='jsonrpc')` not `type='json'`
+- `ir.cron` no `numbercall` field
+- `res.groups.user_ids` not `users`
+- `ir.ui.menu.group_ids` not `groups_id`
+- `from odoo.exceptions import UserError, ValidationError` (NOT `self.env['ir.exceptions'].UserError`)
+
+## Test Targets
+
+Match Phases 1-3 test pyramid. Phase 4 target: ~80-100 additional tests → ~510-530 total project tests.

+# fusion_accounting_followup — Cursor / Claude Context
+
+## Purpose
+
+AI-augmented customer follow-ups (dunning) — a Fusion-native replacement
+for (and coexisting with) Odoo Enterprise's `account_followup` module.
+Ships in Phase 4 of the fusion_accounting roadmap.
+
+## Architecture
+
+Hybrid: the engine (`fusion.followup.engine`, AbstractModel) is the
+SINGLE write surface for the follow-up lifecycle. Everything else
+(controllers, OWL components, AI tools, wizards, cron) routes through
+the engine's 7-method public API:
+
+- `get_overdue_for_partner(partner)`
+- `compute_followup_level(partner)`
+- `send_followup_email(partner, level=None, force=False)`
+- `escalate_to_next_level(partner)`
+- `pause_followup(partner, until_date=None)`
+- `reset_followup(partner)`
+- `snapshot_followup_history(partner, limit=50)`
+
+Pure-Python services live in `services/`:
+
+- `overdue_aging` — 6 buckets (current, 1-30, 31-60, 61-90, 91-120, 120+)
+- `level_resolver` — match aging to a `fusion.followup.level`
+- `risk_scorer` — 0-100 payment-risk score plus structured drivers
+- `tone_selector` — gentle / firm / legal based on level + risk
+- `followup_text_generator` + `followup_text_prompt` — LLM-generated
+  follow-up text with a templated fallback that keeps the feature
+  usable offline
+
+Persisted models in `models/`:
+
+- `fusion.followup.level` — level definition (delay_days, tone,
+  mail_template_id, requires_manual_review, sequence)
+- `fusion.followup.run` — per-partner audit record (state, level,
+  amount, ai-generated flag, error captured)
+- `fusion.followup.text.cache` — LLM cost-saving cache keyed on
+  (partner, level, tone, prompt fingerprint)
+- `fusion.followup.engine` — AbstractModel (the API)
+- `fusion.followup.cron` — cron handlers (daily scan, weekly risk refresh)
+- `res.partner` (inherits) — adds `fusion_followup_status`,
+  `fusion_followup_paused_until`, `fusion_followup_last_level_id`,
+  `fusion_followup_risk_score`, `fusion_followup_risk_band`
+- `account.move.line` (inherits) — adds `fusion_followup_level_id` and
+  `fusion_followup_last_run_date`
+
+Wizards (TransientModel) in `wizards/`:
+
+- `fusion.batch.followup.wizard` — bulk-send across all overdue
+  customers, a manual selection, or a level-filtered subset; supports
+  `auto_resolve_level`, `override_level_id`, and `force` flags
+
+Controllers: `controllers/followup_controller.py` exposes 6 JSON-RPC
+endpoints under `/fusion/followup/*` (`list_overdue`, `get_partner`,
+`compute_level`, `send`, `escalate`, `pause`, `reset`, `history`,
+`generate_text`). All calls route through the engine.
+
+OWL frontend: `static/src/`
+
+- `services/followup_service.js` — central reactive state + RPC wrappers
+- `views/followup_dashboard/*` — top-level dashboard view
+- `components/risk_badge`, `partner_card`, `aging_bucket_strip`,
+  `ai_text_panel`, `followup_history_table` — 5 components
+- `scss/_variables.scss` + `followup.scss` + `dark_mode.scss`
+- `tours/followup_tours.js` — 5 OWL tour smoke tests
+
+Default data:

+- `data/followup_levels_data.xml` — 3 default levels

+- `data/mail_templates_data.xml` — 3 mail templates wired to the levels

+
+## Coexistence
+
+When `account_followup` is installed the Customer Follow-ups menu hides
+via `fusion_accounting_core.group_fusion_show_when_enterprise_absent`.
+The engine + AI tools always remain available for the chat / API. The
+migration step in `fusion.migration.wizard` backfills
+`fusion.followup.level` records from existing
+`account_followup.followup.line` rows (idempotent — skips rows already
+linked via the `legacy_followup_line_id` column).
+
+## V19 Conventions Applied
+
+- `_sql_constraints` → `models.Constraint` (every persisted model)
+- `@api.depends('id')` → not used (would raise `NotImplementedError`)
+- `@route(type='json')` → `type='jsonrpc'` (all 6 endpoints in
+  `controllers/followup_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)
+- SCSS: `@import "variables"` is forbidden in V19; rely on manifest
+  asset concatenation order (`_variables.scss` first)
+- OWL `t-on-click` arrow handlers must use an explicit `this.` reference
+
+## Performance baseline (Task 21)
+
+| Operation                              | P95   | Budget   |
+|----------------------------------------|-------|----------|
+| `engine.compute_followup_level`        |  0ms  |  50ms    |
+| `engine.get_overdue_for_partner`       |  1ms  | 100ms    |
+| `engine.send_followup_email` (no due)  |  0ms  | 200ms    |
+| `controller.list_overdue` (20 ptrs)    | 100ms | 500ms    |
+
+(Engine ops measured against partners with no overdue lines — these are
+floor measurements; load-driven scaling is verified in
+`test_performance_benchmarks.py`.) All Phase 4 perf metrics are within
+1x of budget; no optimization needed at ship.
+
+## Test counts (Phase 4 ship)
+
+- 106 logical tests in `fusion_accounting_followup`
+- 0 failures, 0 errors
+- Coverage includes: 4 engine + 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,
+  cron tests, batch wizard tests, coexistence tests, migration
+  round-trip test.
+
+## Known concerns / Phase 4.5 backlog
+
+- `risk_scorer._compute_risk` `paid_late_count` and `avg_days_late` are
+  placeholders; full reconciliation traversal deferred for performance.
+- Migration tone heuristic could misclassify Enterprise levels with
+  non-standard sequence numbers (numeric sequence outside 1/10/100
+  buckets).
+- `pause_followup` / `reset_followup` do not `sudo()` the partner
+  write — could fail for non-admin users without partner-write rights.
+- Email send is best-effort — failure is captured on the
+  `fusion.followup.run` record but does not raise.
+- `followup_text_generator` always returns a usable dict (templated
+  fallback when LLM absent), so callers can't distinguish "AI said so"
+  from "fallback fired"; the `tone_used` and absence of `key_points`
+  are the only signals.
+- Sub-second SLA on `controller.list_overdue` for partner counts > 200
+  is not yet stress-tested.

+# fusion_accounting_followup
+
+AI-augmented customer follow-ups (dunning) for Odoo 19 Community — a
+Fusion-native replacement for Enterprise's `account_followup` module.
+
+## What it does
+
+- Multi-level dunning sequences (gentle reminder, firm warning, legal
+  notice) with delay-day cadence per level
+- 6-bucket aging analysis (current, 1-30, 31-60, 61-90, 91-120, 120+)
+  per customer
+- Per-partner follow-up state machine (`current`, `action_due`,
+  `paused`, `blocked`, `with_credit_team`)
+- Daily cron that scans overdue customers and queues / sends follow-ups
+- Weekly cron that refreshes the AI risk score on every overdue customer
+- Mail templates per level, with per-partner context interpolation
+- Batch wizard for bulk-send across all overdue customers, an
+  arbitrary selection, or a level-filtered subset
+- Per-partner follow-up history with state, level, and amount audit
+- AI augmentation:
+  - **Payment-risk scoring** — 0-100 score plus structured drivers
+    (paid-late ratio, longest-overdue band, recent dispute, etc.)
+  - **Tone selection** — gentle / firm / legal based on level + risk
+  - **Follow-up text generation** — LLM-driven subject + body keyed
+    on tone, with a templated keyword fallback so the feature still
+    works offline
+- Coexists with Enterprise `account_followup` (Enterprise wins by
+  default; the Fusion menu only appears when Enterprise is uninstalled)
+- Migration-aware: bootstrap step backfills `fusion.followup.level`
+  records from existing `account_followup.followup.line` rows so the AI
+  has memory from day 1
+
+## Quick start
+
+```bash
+# Install (sub-module)
+odoo --addons-path=... -i fusion_accounting_followup
+
+# Or install the whole suite via the meta-module
+odoo --addons-path=... -i fusion_accounting
+
+# Open the dashboard (when Enterprise's account_followup is NOT installed)
+# Apps -> Customer Follow-ups -> Overdue Customers
+
+# 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.followup_text` = `openai`
+
+## Public API (engine)
+
+`fusion.followup.engine` is the single write surface. See `CLAUDE.md`
+for the full 7-method signature list.
+

+# fusion_accounting_followup — Upgrade Notes
+
+## Odoo Version Anchor
+
+This module targets **Odoo 19.0** (community-base).
+
+Reference snapshot of Enterprise code mirrored from:
+- `account_followup` (Odoo 19.0.x)
+- Source: `/Users/gurpreet/Github/RePackaged-Odoo/accounting/account_followup/`
+
+## 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_followup.followup.line`,
+   `res.partner` follow-up fields, or mail-template invocation 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 and any deviations
+
+## V19 Migration Notes (already applied)
+
+- `_sql_constraints` → `models.Constraint` (every persisted model)
+- `@api.depends('id')` → not used (would raise `NotImplementedError`)
+- `@route(type='json')` → `type='jsonrpc'` (all 6 endpoints in
+  `controllers/followup_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)
+- SCSS: `@import "variables"` removed; manifest concatenation order
+  (`_variables.scss` first) provides the variables to the rest of the
+  asset bundle
+- OWL `t-on-click` arrow handlers always close over an explicit `this.`
+
+## Phase 4 → Phase 4.5 Migration
+
+If we ship Phase 4.5 (full `paid_late_count` traversal, sub-annual
+follow-up cadences, multi-currency aggregation in `risk_scorer`,
+admin-only pause sudo wrapper), changes will go in incremental commits.
+No DB migration needed (Phase 4 schema is forward-compatible — new
+columns will be nullable / default-valued).
+
+## Coexistence with Enterprise `account_followup`
+
+The migration step in `fusion.migration.wizard` backfills
+`fusion.followup.level` records from existing
+`account_followup.followup.line` rows. It is idempotent (skips rows
+already linked via the `legacy_followup_line_id` column).
+
+When `account_followup` is installed the Customer Follow-ups menu hides
+via `fusion_accounting_core.group_fusion_show_when_enterprise_absent`.
+The engine and AI tools remain available for chat-driven workflows.
