704bf93e08 feat(categorize): confidence calibration engine + measurement loop (cascade step 4) (#1784)
Turns the selector's raw confidence into a score that means what it says.

- lib/agent/categorize/calibration.ts: the engine. Isotonic regression
  (pool-adjacent-violators, distribution-free + monotonic) over
  (confidence, was_correct) samples → a calibrator; plus reliabilityByBucket,
  ECE, and bandFor(). bandFor NEVER returns 'auto' without a fitted calibrator
  (no silent booking on an unproven score) and never auto-books above an amount
  cap. 12 engine tests (overconfidence pulled down, underconfidence lifted,
  monotonicity, ECE, band gating).
- Measurement loop: migration categorize_calibration_samples (append-only,
  company-scoped RLS, confidence CHECK [0,1]) + POST /api/agent/categorize/
  outcome logging one sample (proposed vs actually booked) fire-and-forget from
  QuickReviewDialog on a successful book (sandbox skipped). AiCategorizeProposal
  surfaces the proposal metadata via onProposal.
- scripts/fit-categorize-calibration.ts (read-only): prints the reliability
  diagram + ECE + fitted calibrator once data has accumulated.

Fitting needs a few hundred real outcomes, so nothing calibrates today — the
loop starts collecting, and "säker" stays uncalibrated (no auto-book) until the
data proves it. 131 unit tests green; RLS covered by a pg-real test.

Why Accounted?

Compliant by construction. Accounted implements double-entry bookkeeping under Swedish accounting law (Bokföringslagen). Voucher immutability, sequential voucher numbering, period locks, and 7-year document retention are enforced by database triggers, not by convention. Corrections are made the legal way, with reversal entries (storno), never by editing history. See ARCHITECTURE.md for how.

Agent-native. The full bookkeeping engine is exposed as 100+ MCP (Model Context Protocol) tools with scoped API keys, so an AI agent can do the books in Accounted: categorize transactions, draft vouchers, reconcile periods, and prepare declarations. Posting is staged for human approval, so the agent proposes and you decide.

Yours to run. AGPL-3.0 licensed and fully self-hostable with Docker and Supabase. Use the hosted version at app.gnubok.se or run your own.
