Mattsson 26e29f47bc feat(company): ideell förening as a third legal form, behind a flag (#2072 step 1) (#2423) 
* feat(company): ideell förening as a third legal form, behind a flag (#2072 step 1)

Why the problem occurred: the legal form was modelled as a binary flag in
~300 files. `EntityType` was a two-member union, but nothing dispatched on it
exhaustively: 28 sites defaulted `?? 'enskild_firma'` (invoice, categorize,
match, stripe, invoice-inbox) or `?? 'aktiebolag'` (year-end, bokslut,
MCP), and every form-dependent choice was an `=== 'aktiebolag' ? A : B`
ternary. Widening the union compiled everywhere and changed nothing, so a
förening would have booked as an enskild firma in the app and as an
aktiebolag in bokslut and MCP, with no error anywhere. The lookup refused
föreningar at the door (mapEntityType returned null), which is what the
tester hit.

What was removed or simplified: the silent defaults. One module,
lib/company/entity-type.ts, now holds the list (ENTITY_TYPES), the parser
(never defaults), the resolver (settings hint, then companies.entity_type,
then throw) and `byEntityType`, whose Record arms make the compiler refuse
the next widening until each site has an answer. The form-dependent facts
(closing account, owner settlement account, calendar-year lock, default
method, K1/K2 label, personnummer vs 16-prefix) live there once instead of
in the ternaries. On the SQL side supported_entity_types() replaces four
copies of the literal list in the create RPCs.

Why this shape and not the proposed one: the tracker asked for the enum
widening plus a chart; that alone was the dangerous version (compiles, books
wrong). Bundling stiftelse was considered and dropped: identical plumbing but
no chart block. Creation sits behind NEXT_PUBLIC_IDEELL_FORENING_ENABLED so
the CHECK, RPCs and seed can ship now and the first partner is switched on
without a migration; the flag goes when Phase 2 (packs, INK3, årsbokslut,
Swish) lands on the tracker.

Domain choices (DECISIONS.md 2026-09-08, verify with an accountant before
Phase 2): result closes to 2069 with 2068 as prior-year carry; no owner
accounts, member settlement on 2890; accrual default; brutet räkenskapsår
allowed; K1 label for the 5 000 kr accrual threshold (BFNAR 2010:1); org
number gets the 16 prefix.

Migration 20260908110835 widens the three CHECK constraints, adds
supported_entity_types(), re-creates the three create RPCs with the widened
guard and adds the förening block to seed_chart_of_accounts. Applied to
staging and covered by ideell-forening-entity-type.pg.test.ts.

* fix(company): close the förening paths the skeptic refuted (#2072)

Five refutations from the /skeptic pass on 7a05c54d2, each fixed at the
shared definition rather than the reported site:

1. Privately paid supplier invoices and the utlägg dialog resolved the owner
   account in lib/expenses/payer.ts with its own AB/EF ternary, so a förening
   member's invoice was built on 2893 and then refused by the expense-claim
   service (which already said 2890), burning an ankomstnummer. The helper now
   uses ownerSettlementAccount.
2. Booking templates substitute their `_ab` accounts only for an aktiebolag;
   the `private_expense` template kept its base 2013 for a förening. Template
   accounts now resolve through templateAccountForForm: EF base, AB override,
   förening base with owner accounts translated to 2890 (booking-templates.ts
   and proposal-lines.ts share it).
3. A VAT-registered förening with helårsmoms got no momsdeklaration deadline:
   the annual VAT rule bailed on anything but AB/EF. A förening is a juridisk
   person and follows the räkenskapsår schedule (SFL 26 kap 33 §), so the rule
   now keys on fiscalYearLockedToCalendar instead of the two literals; same in
   the MCP VAT report.
4. 2069 would have accumulated across years: the year-open omföring was
   AB-only with 2099/2098 hard-coded. planResultAppropriation now takes the
   pair from resultClosingAccounts (AB 2099 -> 2098, förening 2069 -> 2068)
   and skips forms with no carry (EF).
5. With the flag off, a registry lookup that returned "Ideell förening" was
   prefilled into the onboarding journey, the form picker was skipped and the
   create step answered "Ogiltig företagsform" with no way back. The
   journey, the BankID picker, the onboarding page and the MCP lookup now use
   mapSetupEntityType, which maps only creatable forms, so a flagged-off form
   falls through to the picker as before.

Also: form picker keeps its AB-first order; tests for each fix.

Jakob Wennberg 91e2c66afc fix(parties): readable suggestions from assistant vouchers, auto-build queue, SCB fetch after promotion (#2259) 
* fix(parties): readable suggestions from assistant-written vouchers, auto-build queue, SCB fetch after promotion

Live feedback on a real company (2026-09-03): the queue showed 35 one-off
suggestions with sentence-long names, wide empty rows, a "Hämta förslag"
step nobody could predict, no SCB fetch after promotion, and an empty
supplier created from a Finansinspektionen fee line.

- ledger_key v2 (migration 20260904002000): keep the counterpart head of
  "<counterpart> · <note>" descriptions, drop bank method tokens and long
  references before normalising; JS mirror in lib/parties/ledger-key.ts
  with shared LEDGER_KEY_CASES. Suggested parties nobody has touched are
  rebuilt under the new keys (repair in the same migration).
- apply_party_suggestions attaches by VAT number too, so ledger keys with
  a VAT number but no org number reach existing roles.
- Queue: fixed name/reason column widths, inline "Hitta i
  företagsregistret" for rows without an org number.
- Page: builds the queue automatically on first visit when nothing has
  been suggested yet; after promotion, fetches SCB facts for every
  promoted legal person (spaced under the 10 calls/10 s limit) and fills
  the role's VAT number; confirm dialog says how many rows lack an org
  number.
- Classifier: more authorities (Finansinspektionen, Arbetsförmedlingen,
  Pensionsmyndigheten, ...) and fee words (registreringsavgift,
  tillsynsavgift, ...) so fee lines stop becoming suppliers.

* fix(parties): scope the suggestion repair to keys the new ledger_key no longer produces

Superagent flagged the repair DELETE as global. It now only removes
untouched pipeline suggestions that no posted voucher of the company maps
to under the new function; suggestions whose key is unchanged stay.

Jakob Wennberg 18cbc4c30a fix(security): audit remediation 2026-09-01: api_keys identity, viewer gates, OAuth binding, XSS, MFA gate (#2155) 
* fix(security): bind api_keys to the caller, lock hash-as-bearer RPCs and provider token tables

Security audit 2026-09-01, critical items.

- api_keys INSERT requires user_id = auth.uid() again (an admin could
  forge a key for any co-member and act as them in every company they
  belong to); SELECT is own-keys-or-admin; a BEFORE trigger freezes the
  identity and credential columns against user-session UPDATEs.
- rotate_mcp_refresh_token and validate_and_increment_api_key become
  service_role only: they match rows by a presented SHA-256, so a hash
  readable by co-members was a bearer credential.
- validate_and_increment_api_key fails closed when the key's user is no
  longer a member of the key's company.
- provider_consent_tokens and provider_otc: the DELETE policies collapsed
  to "caller has any team row" (correlated subquery on a non-existent
  team_members.company_id). All member policies dropped; service_role
  only, matching every existing code path.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

* fix(security): role gates, ownership guards and posting integrity in the database

Security audit 2026-09-01, high items at the database layer.

- One table-level guard, enforce_company_writer_role(), blocks the
  read-only viewer role on 55 company-scoped tables including through
  the 15 membership-only SECURITY DEFINER writers. Keyed on the JWT role
  claim so it fires inside definer bodies; no-op for service_role and
  trigger cascades.
- company_members user_id/company_id immutable from user sessions;
  invitations can never grant owner; team_members gains a transition
  guard (admins keep non-owner role moves); companies team_id and
  archiving are owner-only and team attachment needs team membership.
- Direct statements (current_user = authenticated) can no longer insert
  posted headers, add lines under posted verifikat, or post a draft with
  a voucher number the sequence never issued. Sanctioned RPCs run as the
  definer and are untouched; the engine's own draft-then-post shapes
  still pass.
- create_document_version refuses viewers and foreign storage paths;
  validate_version_chain needs membership and loses anon EXECUTE;
  match_documents / match_booking_templates lose anon; cron maintenance
  RPCs become service_role only; the production-only
  seed_asset_categories is dropped.

* build: pin tsx as an exact devDependency instead of fetching it with npx at build time

prebuild ran "npx tsx" with no lockfile entry, so every Vercel, Docker
and CI build downloaded tsx@latest and its transitive tree from the
registry with no integrity check, inside the build environment.

* fix(security): refuse the viewer role on API-key and MCP write paths

The v1 wrapper and the MCP company routing checked company membership
but never role, and both run as service role, so a read-only viewer
holding an API key could post vouchers and change settings through the
API. Mutating methods and non-read scopes now return 403 ROLE_READ_ONLY
for viewers on v1; MCP write tools refuse viewers the same way.

* fix(security): stop serving uploaded SVG, XML and HTML as executable content on the app origin

Uploads persisted the browser-declared mime type and the inline proxy
served it verbatim, sandboxing only text/html; the storage proxy
forwarded the uploader's Content-Type. Any writer, or any Peppol sender,
could plant a scripted SVG or XHTML that executed on app.gnubok.se.

- inline route: allow-list of natively safe types (PDF, raster images)
  served as before; everything else gets the opaque sandbox CSP.
- storage proxy: octet-stream + attachment + sandbox unless the DB
  mime for the key is on the allow-list.
- document-service: the stored mime is the magic-byte validated type.
- logo upload: magic-byte validation, SVG refused.

* fix(security): byrå brand logo upload decides the type by magic bytes and drops SVG

Same pattern as the company logo route: the logos bucket is public, so a
scripted SVG (or anything declared as an image) must never land there.
The upload pickers stop advertising SVG.

* fix(security): bind Enable Banking, Stripe and WooCommerce callbacks to the initiating user

The callbacks resolved the pending row by oauth_state alone, so a
victim who completed an attacker-initiated consent had their bank
account, merchant account or store attached to the attacker's company.
requireFlowInitiator() now requires the cookie session of the user who
started the flow: no session redirects to login with the callback URL
preserved, a different user is refused and nothing is exchanged.

* fix(security): guard tenant-controlled outbound fetches and surface the disabled rate limiter

WooCommerce and Shopify syncs fetched a member-editable store URL with
plain fetch() and redirect following under the service role, and the
invoice PDF renderer fetched company_settings.logo_url unguarded. All
three go through a new safeFetch() (public-IP validation via url-guard,
https only, redirect: 'manual', body size cap) and re-normalise the
stored host at use time. checkRateLimit() keeps failing open on hosted
but logs one error per process when Upstash is not configured and
exports isRateLimiterConfigured().

* fix(security): decide the API MFA gate from server-authenticated factors, not the session cookie

getAuthenticatorAssuranceLevel() without arguments derives nextLevel
from session.user.factors, which comes from the unsigned sb-*-auth-token
cookie. Deleting factors from the cookie made an enrolled account look
like it had nothing to step up to, on every /api route and in
requireAuth. Both gates now read factors from the getUser() result or
listFactors() and the level from the verified JWT claim, and fail closed
on errors. Page-branch gate hardened the same way.

* fix(security): bind Fortnox/Visma, Gmail and Skatteverket callbacks to the initiating user

The arcim-migration callback exchanged the provider code onto whatever
consent the one-time state named, with no check of who completed the
flow and no org-number comparison, so a phished Fortnox admin handed
their ledger to the attacker's company. provider_otc now records the
initiating user (migration 20260902100000); the callback requires that
session and, after the exchange, refuses a provider company whose org
number differs from the consent's company. The Gmail and Skatteverket
callbacks enforce the same initiator check.

* fix(security): BankID signup confirms the email before linking the identity

Signup created an email-confirmed, MFA-exempt account for any address
the caller typed and returned a magic link, so an attacker could
pre-register a victim's email and keep a permanent BankID login into the
account the victim later adopted. The user is now created unconfirmed,
the identity carries email_verified_at NULL (migration 20260902101000),
bankid_linked is not set until the mailed confirmation is clicked, and
BankID login of a pending identity is refused with the confirmation
re-sent.

* fix(security): bind MCP OAuth redirect URIs to the consenting user and cap scopes

A user-registered redirect URI was allowlisted globally, the consent page
named no client, and all scopes were pre-checked, so one phishing link
handed an attacker a full-scope key for the victim's company. Registered
URIs now resolve only for the registrant or a colleague sharing a
company; the consent page shows the client identity and redirect host;
non-built-in clients default to read-only pre-checks; scopes are capped
by the user's role (viewer: read only) at consent and at /token.

* fix(auth): client follow-ups for BankID confirmation, callback mismatch copy and decision log

- register client handles the new confirmation_sent response from BankID
  signup with the existing inbox screen instead of calling verifyOtp.
- BankID login surfaces the email_unconfirmed explanation.
- WooCommerce settings map woocommerce_error=wrong_user to its own copy.
- Logo help text no longer advertises SVG.
- DECISIONS.md records the audit remediation choices.

Mattsson 2814d70cb4 feat(bookkeeping): Fortnox-style inline IB correction + cascade to later years (#2076) 
* feat(bookkeeping): cascade opening-balance corrections to later years

Fortnox/SIE migrations book one IB verifikat per imported year, so
correcting one year's ingaende balans left every later year's linked IB
carrying the stale figures (support case: a 2019 IB fixed in Fortnox
after export never reached Accounted, skewing all subsequent saldon).

- POST /api/import/opening-balance/correct accepts cascade: true and
  applies the correction's per-account delta to each subsequent year's
  IB via storno + rebook + relink (lib/import/opening-balance/cascade.ts).
  Locked/closed/lock-dated/bokslut years are skipped and reported, never
  forced; a failed year is compensated and the cascade continues.
- CorrectOpeningBalanceDialog offers the cascade as a default-checked
  checkbox when later years have their own IB verifikat, and when the
  current year is blocked it points at the earliest open year's IB
  verifikat instead of dead-ending.

* fix(bookkeeping): atomic cascade replacement + review findings for PR #2076

- Cascade now books each later year through replaceOpeningBalanceEntry
  (one RPC transaction: storno + corrected voucher + pointer swap, CAS
  on the expected old entry), removing the create/reverse/relink window
  that could leave a period linked to a reversed IB entry.
- Cascaded verifikat keep the original lines verbatim (descriptions and
  dimensions) and append labelled IB-rättelse adjustment lines per
  changed account instead of collapsing per-account nets.
- Year-end lookup fails closed: a query error skips the period instead
  of reading as 'no bokslut'.
- Dialog always sends the cascade flag (a cold reference cache no longer
  silently disables the default-on cascade), the success toast separates
  blocked years from failed years needing review, and the checkbox notes
  that a resultat correction may still need an omforing to 2091.

* feat(bookkeeping): Fortnox-style inline IB correction without storno

Founder decision 2026-08-31: IB edits in open unlocked years should feel
like Fortnox (change the number, no extra verifikat) instead of always
producing a storno + rebook pair in serie A.

- Migration 20260831150000 redefines correct_entry_lines_inline to admit
  source_type 'opening_balance' with three IB guards: only the period's
  current linked IB, no posted bokslut on the period, and replacement
  lines restricted to balance-sheet accounts (class 1-2). The entry id
  never changes, so fiscal_periods.opening_balance_entry_id stays valid
  and every report reads the corrected lines automatically. Storno,
  year_end and vat_settlement stay excluded; locked/closed/lock-dated
  periods are still refused (BFL 5 kap 5 par: storno is the only track
  there).
- New POST /api/import/opening-balance/correct-inline: diff-based strike
  and replace inside the same IB verifikat, same OB_* pre-flight codes
  as the storno route, RPC rule violations surfaced verbatim as 409
  OB_INLINE_REFUSED. With cascade: true the per-account delta is
  appended as labelled IB-rattelse lines inside each later open year's
  own IB verifikat (cascade mode 'inline'): a multi-year correction
  with zero new verifikat.
- CorrectOpeningBalanceDialog computes the row diff (untouched lines
  keep ids, descriptions and dimensions) and posts to the inline route;
  copy updated (no storno language), toast reports inline updates.
- In-app agent guidance (shared-rules) updated to describe the inline
  flow and the cascade checkbox.
- Tests: pg-real suite for the redefined RPC (IB accept, linked-IB
  guard, bokslut guard, P&L guard, structural types still refused,
  non-IB unaffected), route tests, cascade inline-mode unit tests.

The storno-based /correct route and engine paths are untouched: they
remain for the import replace flow and API compatibility.

* fix(agent): avoid the BFL 5 kap 5 par marker string in IB guidance

The verifikation-draft period-lock gate test uses the literal
'BFL 5 kap 5 §' as a marker for locked-period-only guidance; the new IB
bullet in shared-rules carried the same string in every prompt and broke
the open-period assertion. Reference Bokföringslagen generically instead.

* fix(bookkeeping): derive inline cascade delta from the rattelse log

Swedish-review finding on PR #2076: the cascade delta was computed from
a route-side line snapshot read before the RPC, which a concurrent edit
could theoretically desync from what the RPC actually committed. The
delta now comes from the RPC's own journal_entry_rattelse_log row
(struck_lines/added_lines snapshotted inside the RPC transaction), so
the cascade always matches the committed base correction. Also softened
the blocked-year guidance copy (declared-status is an assumption, not a
verified fact).

* fix(bookkeeping): visible cascade failure + dimensions-aware no-op check

CodeRabbit round-2 findings on PR #2076:
- A cascade that failed to run (log fetch error, unexpected throw) was
  returned as an empty successful summary, so the dialog reported
  nothing wrong while later years stayed unverified. Both routes now
  mark it failed: true and the dialog tells the user to check later
  years' opening balances.
- The RPC's no-op guard compared account/amount/description only, so a
  dimensions-only rattelse raised 'Rattelsen andrar ingenting'. The
  comparison keys now include canonical dimensions jsonb text (fixed in
  the unmerged 20260831150000 migration).

Jakob Wennberg 304baf1089 chore(ci): ratchet TypeScript errors, because npm test does not typecheck (#1980) 
Vitest transpiles and discards types, so a type error passes all 18 000 tests
and only surfaces in npm run build several minutes later. That happened twice
on 2026-08-27: a widened union in the MCP server that a second declaration in
lib/events/types.ts still contradicted, and an interface that would not assign
into Record<string, unknown>[] because interfaces have no implicit index
signature. Both were caught by the build. Neither was caught by the tests,
which is the wrong order to learn it in.

This is not just a faster copy of the build job. tsc --noEmit also covers
__tests__ files, which the Next.js build never compiles, and that is where all
539 baseline errors live.

Baselined per FILE rather than per error code, unlike the lint ratchet: the
legacy errors sit in a handful of old test files and TS2322 is common enough
that a code-keyed budget would let a real regression hide behind a legacy fix
somewhere else.

Measured: 36s cold, which is what CI pays, and 4.4s warm locally.

Verified the gate fires by introducing a deliberate type error and watching it
fail with the exact location, then restoring.
