Jakob Wennberg 4a0b524fbb fix(categorization): connect card descriptors to counterparty history (#1095)
* fix(categorization): connect card descriptors to counterparty history

suggest_categories returned no signal for recurring card merchants
(reported: Anthropic booked to 5420 fourteen times, zero suggestions).
Three compounding causes, all fixed:

- normalizeCounterpartyName() now reduces card-network descriptors to
  their merchant segment ("ANTHROPIC* CLAUDE SUB SAN FRANCISCO" ->
  "anthropic"; "PAYPAL *SPOTIFY" -> "spotify"), so monthly per-charge
  tails stop splintering one merchant into unmatchable variants. SQL
  mirror normalize_counterparty_key() updated in lockstep (migration
  20260721140000), keeping the ledger-context template join exact.
- New token_subset match tier bridges templates learned from manual
  bookings ("Claude Dec" -> "claude") to bank descriptors containing
  the token, and card-core descriptors to legacy splintered templates.
  Guarded by a distinctive-token filter so generic/geo words never
  match on their own.
- Merchant history falls back to description when merchant_name is
  null: card purchases never carry merchant_name, so the history path
  was structurally blind to exactly the transactions that need it.
  History keys now share the counterparty-template normalization and
  the 200-row window is ordered by recency.

* fix(categorization): guard single-token matches, anchor history on original_description

Review follow-ups (CodeRabbit on #1095):

- token_subset tier: a single shared distinctive token now also requires
  occurrence_count >= 3 on the template, so a template named after a
  common word or first name (one prior booking) cannot vacuum up
  unrelated transfers ("SWISH ANDERS JOHANSSON"). Multi-token agreement
  stays unrestricted; the Claude/Anthropic case (14 bookings) is
  unaffected.
- merchant history keys on original_description ?? description: the raw
  bank descriptor is immutable while description is a user-editable
  working title, so renaming a transaction no longer severs its history
  link for future recurring charges.

* chore(migrations): re-timestamp card-descriptor migration after prod moved past it

Prod applied 20260721144311 (#1101) through 20260721201747 (#1104) while
this PR was open; 20260721140000 would sort before them and risk being
skipped by out-of-order auto-apply at merge. Not yet applied to prod, so
renaming is safe; the preview branch re-applies idempotently
(CREATE OR REPLACE).

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.
