+# 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_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).

+# fusion_accounting_reports — Cursor / Claude Context
+
+## Purpose
+
+AI-augmented financial reports — a Fusion-native replacement for Odoo
+Enterprise's `account_reports` module. Phase 2 of the fusion_accounting
+roadmap.
+
+CORE scope:
+- Income Statement (P&L)
+- Balance Sheet
+- Trial Balance
+- General Ledger (with drill-down)
+
+AI augmentation:
+- Anomaly detection (variance vs prior period)
+- AI commentary (LLM-generated narrative)
+
+## Architecture
+
+Hybrid: the engine (`fusion.report.engine`, AbstractModel) is the SINGLE
+read surface for reports. Per-report definitions are stored as `fusion.report`
+records with JSON `line_specs` so non-developers can tweak the layouts.
+
+Public engine API (5 methods):
+- `compute_pnl(period, *, comparison='none', company_id=None)`
+- `compute_balance_sheet(date_to, *, comparison='none', company_id=None)`
+- `compute_trial_balance(period, *, company_id=None)`
+- `compute_gl(period, *, account_ids=None, company_id=None)`
+- `drill_down(*, account_id, period, company_id=None)`
+
+Pure-Python services in `services/` (no Odoo imports — independently
+unit-testable):

+## Coexistence
+
+When `account_reports` is installed, the Reports menu hides via
+`fusion_accounting_core.group_fusion_show_when_enterprise_absent`
+(a computed group). The engine + AI tools (commentary, anomaly detection)
+remain available for the chat regardless.
+
+## 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`).
+
+- **Engine signature:** Public methods are keyword-only after the leading
+  positional `period` / `date_to`. Always pass `company_id=...` explicitly.
+
+- **`fusion.report` lookup:** `_get_report` falls back from per-company
+  override to global (`company_id=False`) — order is `company_id desc nulls
+  last`.
+
+- **Materialized view refresh:** `fusion.account.balance.mv` rebuilds via a
+  dedicated autocommit cursor (REFRESH CONCURRENTLY can't run inside Odoo's
+  regular transaction). Triggered by cron + on demand from the engine when
+  data is older than the configured TTL.
+
+- **JSON `line_specs`:** Strings prefixed `account:`, `prefix:`, `formula:`
+  or `header` — `line_resolver.py` resolves each spec to a row. Header rows
+  have no compute payload and are silently skipped by downstream totals.
+
+- **Commentary cache:** Keyed on `(report_id, company_id, period_from,
+  period_to, comparison_mode)` with a unique constraint. Re-runs use the
+  cache unless `force_refresh=True`.
+
+## Test counts (Phase 2 ship)
+
+- 130 logical tests, 0 failed, 0 errors
+- Includes:
+  - 6 benchmarks (tagged `benchmark`)
+  - 1 LLM compat smoke (tagged `local_llm`, skips when no LLM)
+  - 5 OWL tours (tagged `tour`, skips without `websocket-client`)
+  - Property-based, integration, controller, materialized-view, coexistence,
+    migration round-trip, PDF/XLSX export
+
+## Performance baseline
+
+| Operation | Median | P95 | Budget |
+|---|---|---|---|
+| `engine.compute_pnl` | 3ms | 8ms | <2000ms |
+| `engine.compute_balance_sheet` | 15ms | 20ms | <2000ms |
+| `engine.compute_trial_balance` | 3ms | 8ms | <1000ms |
+| `engine.compute_gl` | 25ms | 81ms | <3000ms |
+| `engine.drill_down` | 2ms | 10ms | <500ms |
+| `controller.run` (HTTP round-trip) | 9ms | 46ms | <2500ms |
+
+All metrics within 1x of budget at Phase 2 ship. Numbers from
+`tests/test_performance_benchmarks.py` against the dev VM
+(`westin-v19`, ~1 fiscal year of data).
+
+## Known concerns / Phase 2.5 backlog
+
+- Trial balance period-only sum doesn't auto-close to retained earnings
+  (drift visible in `test_trial_balance_total_near_zero`, currently skipped)
+- Balance sheet `TOTAL LIABILITIES + EQUITY` math limited (no
+  subtotal-of-subtotals expansion in `formula:` specs)
+- GL `line_specs` need `prefix:` empty-string handling for
+  "all accounts" semantics
+- Header rows (no compute payload) silently skipped by `line_resolver` —
+  fine for layout, but a `header_only=True` flag would be clearer
+- `expense` prefix overlaps with subtypes (`expense_direct_cost`,
+  `expense_depreciation`) — current line_specs need explicit ordering or a
+  longer-prefix-wins rule
+- `wkhtmltopdf` may need configuration for PDF export on first install
+- `ReportsAdapter.run_report` vs `run_fusion_report` naming (legacy clash
+  with Enterprise wrapper)
+- Tour tests skip when `websocket-client` is absent — install it in CI to
+  exercise the OWL surface end-to-end

+# fusion_accounting_reports
+
+AI-augmented financial reports for Odoo 19 Community — a Fusion-native
+replacement for Enterprise's `account_reports` module.
+
+## What it does
+
+- **CORE reports**: Income Statement (P&L), Balance Sheet, Trial Balance,
+  General Ledger (with drill-down to journal items)
+- **AI augmentation**: variance-based anomaly detection + LLM-generated
+  commentary (Claude / GPT / local LM Studio / Ollama)
+- **Wizards**: period picker (common presets — MTD, QTD, YTD, last month,
+  custom range) + XLSX export
+- **Coexists** with Enterprise's `account_reports` (Enterprise wins by
+  default; the Fusion menu appears only when Enterprise is uninstalled —
+  the engine and AI tools are always available via the AI chat)
+- **Multi-currency** aware via `services/currency_conversion.py`
+- **Multi-company** aware (per-company `fusion.report` overrides fall back
+  to global definitions)
+
+## Quick start
+
+```bash
+# Install
+odoo --addons-path=... -i fusion_accounting_reports
+
+# Open the reports menu (when Enterprise's account_reports is NOT installed)
+# Apps → Reports → Open Financial Report
+```
+
+## Configuration
+
+### LLM commentary (optional)
+
+For LM Studio / Ollama (local):
+
+- `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` (or anything non-empty)
+- `fusion_accounting.provider.reports_commentary` = `openai`
+
+For OpenAI / Anthropic, set the corresponding API keys via the
+`fusion_accounting_ai` config screen — `reports_commentary` will route
+through whatever provider you choose.
+
+If no provider is configured, commentary falls back to a deterministic
+templated summary (no LLM call).
+
+### Cron jobs
+
+Two cron handlers live in `models/fusion_reports_cron.py`:
+
+- `fusion_reports_commentary_refresh` — daily, regenerates commentary for
+  the most recently completed period
+- `fusion_reports_mv_refresh` — every 15 min, refreshes
+  `fusion.account.balance.mv`
+
+## Public engine API
+
+```python
+engine = env['fusion.report.engine']
+
+# Income statement
+result = engine.compute_pnl(period, comparison='previous_year')
+
+# Balance sheet (point-in-time)
+result = engine.compute_balance_sheet(date(2026, 12, 31))
+
+# Trial balance
+result = engine.compute_trial_balance(period)
+
+# General ledger (journal items per account)
+result = engine.compute_gl(period, account_ids=[1, 2, 3])
+
+# Drill-down (one account, period)
+items = engine.drill_down(account_id=1, period=period)
+```
+
+## JSON-RPC endpoints
+
+All under `/fusion/reports/`:
+
+- `POST /fusion/reports/run` — single entry-point (dispatches by `report_type`)
+- `POST /fusion/reports/drill_down` — journal items for an account+period
+- `POST /fusion/reports/commentary` — fetch/refresh LLM commentary
+- `POST /fusion/reports/anomalies` — flagged variances for a period
+- `POST /fusion/reports/export_xlsx` — XLSX bytes
+- `POST /fusion/reports/export_pdf` — PDF bytes (via wkhtmltopdf)
+- `POST /fusion/reports/list_definitions` — available `fusion.report` records
+- `POST /fusion/reports/period_presets` — date-range presets for the picker
+
+## Test counts
+
+- 130 logical tests, 0 failures, 0 errors
+- 6 performance benchmarks (tagged `benchmark`)
+- 1 local-LLM compat smoke (tagged `local_llm`, skips without LLM)
+- 5 OWL tour tests (tagged `tour`, skips without `websocket-client`)

+# fusion_accounting_reports — Upgrade Notes
+
+## Odoo Version Anchor
+
+This module targets **Odoo 19.0** (community-base).
+
+Reference snapshot of Enterprise code mirrored from:
+- `account_reports` (Odoo 19.0.x)
+- Source: `/Users/gurpreet/Github/RePackaged-Odoo/accounting/account_reports/`
+
+## 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.move.line` / `account.account` API
+   surfaces relied on by `services/totaling.py` and
+   `services/drill_down_resolver.py`
+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 + benchmarks against the new Odoo
+   version
+5. Update this file with the new version anchor + any deviations
+
+## V19 Migration Notes (already applied — Phase 1 lessons)
+
+These were the bite-points from Phase 1 (`fusion_accounting_bank_rec`); we
+preempted them in Phase 2 from day one:
+
+- `_sql_constraints` → `models.Constraint` (used in `fusion.report`,
+  `fusion.report.commentary`, `fusion.report.anomaly`)
+- `@api.depends('id')` → removed everywhere; computed fields depend on real
+  field names instead
+- `@route(type='json')` → `type='jsonrpc'` (all 8 endpoints)
+- `numbercall` field on `ir.cron` → omitted (removed in V19)
+- `res.groups.users` → `user_ids`
+- `ir.ui.menu.groups_id` → `group_ids` (used in `views/menu_views.xml` and
+  the two wizard view files for the coexistence-group filter)
+
+## Engine API Stability
+
+The 5 public engine methods (`compute_pnl`, `compute_balance_sheet`,
+`compute_trial_balance`, `compute_gl`, `drill_down`) are the public contract.
+Their signatures are keyword-only after the first positional argument and
+will be treated as semver-stable across patch releases. Breaking changes
+will bump the minor version (e.g. 19.0.2.x.y).
+
+## Phase 2 → Phase 2.5 Migration
+
+If we ship Phase 2.5 (line_spec polish, deferred features, header_only
+flag, prefix overlap fix), changes will go in incremental commits. No DB
+migration needed — Phase 2 schema is forward-compatible:
+
+- `fusion.report.line_specs` is a JSON column; the migration path is to
+  rewrite specs in place
+- `fusion.account.balance.mv` can be dropped/re-created freely
+- `fusion.report.commentary` is a cache; safe to truncate on upgrade
+- `fusion.report.anomaly` records carry Period as date_from/date_to fields;
+  no schema-level changes anticipated
