Jakob Wennberg 3a7688c163 fix(enable-banking): only pin hidden, psu-applicable decoupled auth methods (Lunar dead end) (#1529)
* fix(enable-banking): only pin hidden, psu-applicable decoupled auth methods

PR #854 pinned the first DECOUPLED auth method for every bank to fix
Handelsbanken corporate consents (its Mobile BankID is a hidden_method
that Enable Banking only uses when requested explicitly). The blanket
pin also hit banks whose decoupled method is visible and whose default
flow already worked: Lunar users were asked for personnummer on the
hosted page, told to approve in the app, and no approval ever arrived.

Now a method is pinned only when pinning is necessary (hidden_method
is true, so the method is unreachable by default) and applicable
(psu_types missing/empty or containing the consent's psu_type).
Otherwise undefined is returned and the ASPSP default runs, matching
the stated intent of #854. The connect log now records the chosen
method's approach, hidden_method and psu_types so per-bank behavior
can be verified in prod after deploy.

* test(enable-banking): bind pinned auth method to the outgoing /auth request

Review follow-up on the auth-method pinning branch, two findings:

1. No test bound the selection result to the outgoing request: mutating
   the connect route to stop forwarding the pinned method's name into
   startAuthorization (the exact Handelsbanken-corporate regression this
   code exists to prevent) passed all 157 tests. Add route-level wiring
   tests asserting startAuthorization receives 'BANKID' in the
   auth_method argument position (index 5) on both the fresh-connect and
   reconnect call sites, plus the inverse: unpinned resolves to an
   undefined auth_method.

2. The auth_method_psu_types log field printed '(aspsp default)' when a
   method WAS pinned but carried no psu_types (the documented real
   Handelsbanken shape), contradicting auth_method='BANKID' on the same
   line. A pinned method without psu_types now logs '(all)';
   '(aspsp default)' is reserved for the unpinned case.

Both fixes are mutation-verified: reverting either makes the new tests
fail (wiring mutation fails 2 tests, sentinel revert fails 1).

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.
