3b4787d8b9 ML predictions Phase 1 & 2: Budget Forecast tab and Cash Flow upgrades
Phase 1 — Budget Forecast: adds a dedicated first-class tab showing all
monthly budgets with velocity (£/day), forecast month-end total, dual
progress bars, and colour-coded overspend probability badges. Summary
bar shows budgets tracked / at-risk count / total forecast overspend.
Removes the old BudgetAlerts widget embedded in the Spending tab.

Phase 2 — Cash Flow: incorporates known recurring transactions into the
30-day projection (outflows hit on their predicted dates rather than
being smeared as averages), adds sqrt-of-time confidence bands to the
chart, and shows an upcoming recurring payments list with at-risk
highlighting for payments falling on or after the first negative-balance day.

1a2c8efd01 Add pensions module and integrate with tax report
Adds a full pensions feature: SIPP/workplace DC/LISA account metadata,
contribution recording with relief-at-source/net-pay/salary-sacrifice
gross calculations, state pension tracker, annual allowance monitor,
and LISA summary. Pension contributions feed into the tax report
(RAS gross totals, allowance used). Includes two Alembic migrations,
backend service/schema/API, and full frontend pensions page with
cards for allowance, state pension, LISA, and retirement projection.

Also fixes CSRF cookie secure flag (must be false for HTTP deployments)
and extends tax schemas/service to expose pension data in the report.

5ed9c52929 Fix subscriptions page including income transactions
Salary and other income marked is_recurring=True were being returned
alongside expense subscriptions. Added type='expense' filter so only
outgoing recurring transactions appear.

9897d03d91 Add public demo mode with auto-seeding, hourly reset, and Portainer deploy guide
- DEMO_MODE=true env flag: disables password changes and backup endpoints (403),
  exposes GET /demo/status for frontend detection
- Auto-seed on first startup: creates demo user (demo@mymidas.app / demo123)
  with 6 months of transactions, investments, budgets, subscriptions, and tax
  payslips; takes a pg_dump snapshot immediately after for hourly restore
- Hourly reset: resetter Alpine container with cron restores DB from snapshot
  and purges uploaded attachments every hour on the hour
- Frontend: amber demo banner on all pages, login page shows credentials,
  password change disabled with notice, backups section replaced with notice
- demo/ directory: self-contained docker-compose.yml (ports 4001/8091),
  .env.example, reset.sh, and step-by-step Portainer DEPLOY.md

afb5e99bb2 Add recurring transaction detection, subscriptions page, and UK tax reporting
- Recurring service: auto-detects direct debits/subscriptions from CSV imports
  using frequency analysis; manual toggle in transaction detail drawer
- Subscriptions page (/subscriptions): groups recurring payments with monthly
  cost equivalents, next-payment badges, and re-scan trigger
- UK Tax page (/tax): payslips/P60 entry, income tax + NI + CGT + dividend tax
  calculations, configurable rate tables per tax year (pre-seeded 2024/25 and
  2025/26), editable in-app so Budget changes need no rebuild
- Migration 0006: tax_rate_configs, tax_profiles, payslips, manual_cgt_disposals
  with RLS; seeds 2025/2026 rate configs for existing users
- Chart tooltip fix: all Recharts tooltips now use TOOLTIP_STYLE constant so
  they render correctly across all dark/light themes

8ef3bb2965 Fix audit findings: budget editing, dead code, logging, multi-currency
- Add budget editing: updateBudget() API, edit button on budget cards,
  BudgetFormModal adapted for create/update (category locked on edit)
- Remove permanently-broken POST /auth/totp/verify stub and its unused
  TOTPVerifyRequest schema
- Wire getHoldingTransactions() to AssetDetail page — transaction history
  table now shows above the candlestick chart, sorted newest-first
- Fix multi-currency net worth in account_service: account balances are
  now converted to base_currency via ExchangeRate table before summing
- Replace silent bare pass exception handlers with logger.warning() in
  transactions.py (OCR/AI pipeline) and price_feed_service.py (search)
  — ValueError in date/number regex parsing left silent (control flow)

26e2a055db Add AI receipt scanning with OCR pipeline and debug toggle
- OCR pipeline: Tesseract (images) + pdfplumber (PDFs) → AI text prompt →
  rule-based regex fallback; works with any text model, not just vision models
- Scan Receipt toolbar button parses a photo and pre-fills the transaction form;
  receipt image is automatically attached to the created transaction
- AI settings page: provider, API key (AES-256-GCM encrypted), custom URL,
  model, and per-user debug toggle that gates the OCR/AI debug panel
- Fix CSRF cookie secure=False so HTTP deployments work; add 7-day max_age
- Fix attachment_refs missing from _to_response (attachments never appeared in UI)
- Fix multipart boundary lost when Content-Type was set manually in axios calls
- nginx: raise client_max_body_size to 15 MB, add 120s proxy timeout for OCR
- Migration 0005: add ai_debug boolean to users table
- Update README and CLAUDE.md with AI scanning docs and architecture notes

- POST /settings/ai/test sends a minimal text prompt to verify the provider
- Returns ok/message — maps HTTP status codes to human-readable explanations
- 405 → "URL pointing at wrong place, check custom URL has no path suffix"
- 401 → invalid key, 404 → wrong path, 429 → rate limited, etc.
- Test button appears once a key is saved; result shown inline below buttons
