* 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.

* 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

  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.

MattssonandClaude Fable 5 08b1119c7d feat(connect): wire the SKV extension through the connector broker + data proxy (PR6b-2) (#2103)
* feat(connect): wire the SKV extension through the connector broker + data proxy (PR6b-2)

In connector mode (GNUBOK_CONNECTOR_KEY set, no own SKV credentials) the
Skatteverket extension now routes through the hosted connector stack
(#1757) instead of calling Skatteverket directly:

- skvRequestWithAuth routes to the data proxy: base URL maps to a service
  segment (moms/skattekonto/agd-inlamning/agd-period), the user's SKV
  Bearer moves to X-Connector-Upstream-Authorization, the connector key
  authenticates the proxy, and the gateway Client_Id/Client_Secret are
  omitted (the proxy adds Arcim's). Connector-layer 4xx bodies (code
  CONNECTOR_*) are classified before the SKV-shaped 401/403 sniffing so a
  broker refusal surfaces operator guidance (check GNUBOK_CONNECTOR_KEY),
  never APIGW/BankID guidance for knobs the instance does not have.
- OAuth: /authorize starts the consent via the broker's authorize-url
  (persisting its redirect_uri + connector_state), the hosted SKV callback
  bounces the code back to the instance, and exchangeCodeForTokens /
  refreshAccessToken exchange through the broker's /oauth/token,
  unwrapping its { data } envelope. Tokens still rest encrypted on the
  instance; client_id/client_secret never exist there.
- Broker refresh 404 CONNECTOR_NOT_OWNED maps to SESSION_EXPIRED
  (terminal; reconnect fixes); broker 502 stays a raw error so a transient
  SKV outage never re-arms the reconnect banner (#1155).
- getSkatteverketEnvironment() reports 'prod' in connector mode: the
  upstream env is hosted's, and the instance's unset defaults would show a
  false Testmiljo badge on real filings.
- System (CCG/ombud) auth is deliberately not brokered: hosted-only,
  stays direct.

Hosted and own-credentials self-hosts are byte-identical: every branch
gates on skatteverketConnectorMode(), which is null whenever own SKV
credentials exist or no connector key is set. Direct-path tests pin that.

* fix(connect): classify SKV dead-refresh-token dialects broker-side; forward diagnostic headers; connector-aware gateway guidance

Skeptic refutation on PR #2103 (found independently by the correctness and
compliance skeptics): the broker's /oauth/token catch-all collapsed SKV's
terminal dead-refresh-token dialects (404 id_not_found, 400 invalid_grant,
"Refresh Token status is expired": the dominant refresh outcome, per-flow
tokens live 65 minutes) into the generic 502 CONNECTOR_SKV_TOKEN_FAILED, so
a connector instance could never classify ordinary session expiry: raw
English 500s instead of the reconnect flow, staged filing operations
consumed as non-recoverable, crons retrying raw forever.

- Broker /oauth/token: re-codes those dialects as 401
  CONNECTOR_SKV_REFRESH_DEAD, refresh grant only (invalid_grant on the code
  exchange means an expired one-shot code and keeps the generic 502). The
  classifier (isSkvDeadRefreshTokenError) uses the same regex set the
  extension's direct path classifies with.
- Instance dead-token classifier maps CONNECTOR_SKV_REFRESH_DEAD to
  SESSION_EXPIRED alongside 404 CONNECTOR_NOT_OWNED; the generic 502 stays
  a raw error so a transient SKV outage never re-arms the reconnect banner.
- Data proxy: forwards WWW-Authenticate and x-skv-*/x-amzn-*/x-api-*
  response headers (the instance's MISSING_SCOPE classification reads them;
  body-less gateway rejections carry no other signal).
- Instance gateway-refusal guidance is connector-aware: a self-host has no
  SKATTEVERKET_APIGW_CLIENT_ID and no Utvecklarportalen access, so connector
  mode points at /api/connector/status and support instead.

* fix(connect): reject redirects on the instance's broker OAuth requests

CodeRabbit inline finding (CWE-200): the connector-mode authorize-url and
token requests followed redirects by default, so a 307/308 would resend the
connector key (and code/refresh token) to the redirect target. redirect
'error', matching the broker's own postToken rule; the token response must
only ever come from the broker endpoint itself.

37e50c272d feat(connect): Skatteverket broker + data proxy for self-hosted instances (tokens stay on the instance) (#1757)
* feat(entitlements): partition the self-host bypass so connector capabilities fall through to grants; capability_grants.source accepts 'connector'

Sovereign plan WS3 PR3: ships dark, nothing changes for hosted.

- lib/entitlements/keys.ts: CONNECTOR_CAPABILITIES = bank_sync,
  skatteverket, org_lookup, migration (services Accounted operates that a
  self-hosted instance cannot provide itself) + isConnectorCapability().
  Separate from PAID_CAPABILITIES and outside the trial-seed trigger on
  purpose: a hosted company can never hold a connector grant.
- lib/entitlements/has-capability.ts: isPaywallBypassed() -> isBypassedFor(key).
  Hosted: byte-identical (dev / DISABLE_PAYWALL bypass, FORCE_PAYWALL wins,
  else the grant lookup). Self-host: local capabilities always on
  (FORCE_PAYWALL included, as the existing test demands); connector
  capabilities behave like hosted, i.e. dev bypass, FORCE_PAYWALL, else the
  grant lookup where the connector sync will write source='connector' rows.
  getCompanyEntitlements on a self-host: local paid keys + active connector
  keys, state 'paid' with an active connector grant else 'none' (never the
  hosted trial copy).
- Migration 20260820122000: capability_grants.source CHECK gains
  'connector', found through pg_constraint (the CHECK was declared inline
  and auto-named; Postgres stores IN as = ANY, matched accordingly).
  pg-real test: connector accepted, unknown source rejected, upsert on the
  (scope, key, source) identity, trial seed writes no connector rows.
- Tests: self-hosted connector matrix (local all-on without DB, connector
  gated by grant/expiry, dev bypass all-on, FORCE_PAYWALL gates connector
  keys only, bulk resolution, entitlements shape); two pre-existing tests
  that asserted the old "self-host holds connector keys" contract updated
  to the new one.

Verified: full unit suite green, pg-real suite for lib/entitlements green
against a local supabase/postgres with every migration applied, lint
ratchet, guards. Deferred to the instance-wiring PR: adding the connector
extensions to the self-host Docker preset (dead-end upsells until a key can
be issued).

* refactor(entitlements): fold the self-host branch into the existing grants query

One .or(scopeFilter), not two: the duplicated helper pushed the
no-phantom-columns unresolvable-expression count to 380/379. Behaviour is
unchanged; the self-host matrix tests still pass.

* feat(connect): hosted connector-key registry + validate RPC + entitlements endpoint; instance sync writes connector grants hourly

Sovereign plan WS3 PR4 ("key infra enabling manual sales"), stacked on the
entitlement partition (#1747). Nothing is purchasable yet; this is the
plumbing both ends need before the first manually issued key.

Hosted side:
- Migration 20260820123000: connector_keys (SHA-256 key_hash, prefix,
  org_number, pinned instance_url, scopes, status, Stripe ids,
  current_period_end, per-minute rate limit, active_company_count,
  last_seen/synced) and connector_usage_events (per-request metering,
  separate from metered_events whose company_id references hosted
  companies). RLS on, NO policies: service role only. RPC
  validate_and_increment_connector_key copies the api_keys pattern (FOR
  UPDATE, minute window, suspended reported not counted, revoked = no row)
  and is REVOKEd from PUBLIC/anon/authenticated, GRANTed to service_role.
  pg-real test covers validate/count, unknown+revoked, suspended, rate
  limit, execute privileges per role, RLS invisibility, usage cascade.
- lib/connect/contract.ts (shared wire types), lib/connect/hosted/keys.ts
  (generate/hash/validate -> 401/403/429 mapping),
  with-connector-auth.ts (Bearer or X-Connector-Key, one usage row per
  request, 500 envelope on handler throw), /api/connect/entitlements GET +
  POST (records active_company_count, pins instance_url on first report,
  never moves a pinned one), scripts/issue-connector-key.ts (dry run unless
  --confirm, prints the key once + the .env lines).

Instance side:
- lib/connect/instance/config.ts (GNUBOK_CONNECTOR_KEY, GNUBOK_CONNECT_URL
  default https://app.gnubok.se), sync.ts: reports the active company count
  and writes source='connector' grants for every company x covered scope,
  expires_at = min(now+72h, period_end+3d); 401/403 or a non-active status
  deletes them (freeze-and-retain); network/5xx/429 leave them alone.
  /api/connector/sync/cron (hourly) runs it; not_configured without a key.
- Crontab generator gains EXTRA_JOBS (variant-only jobs not in vercel.json,
  with reasons) + drift tests; docker/crontab.self-hosted regenerated with
  the hourly sync. Docs (SELF-HOSTING connector section, env templates),
  DECISIONS.

Tests: 52 new unit tests (keys, auth wrapper, route, config, sync outcomes
and grant arithmetic, cron route, crontab EXTRA_JOBS) + 7 pg-real tests
run locally against supabase/postgres with every migration applied.
no-phantom-columns ceiling +1 with a reason (the bulk grant upsert).

* feat(connect): Enable Banking proxy for self-hosted instances, with a secret-free ownership ledger and a global rate budget

Sovereign plan WS3 PR5a, stacked on the connector-key infra (#1748). A
self-hosted instance with a `bank_sync`-scoped connector key can now connect
a bank through Arcim's PSD2 credentials; the bank session id and all
transaction data stay in the instance's own database (founder decision:
tokens on the instance, proxy stateless).

- Migration 20260820124000: `connector_connections` (secret-free ledger:
  sha256 of the EB session id + account uids, service-role only),
  `connector_upstream_counters` + RPC `connector_reserve_upstream` (global
  budget under EB Annex 1 §5's 300/min, shared with hosted), and
  `connector_keys.limits` jsonb; validate RPC v2 returns limits. All RPCs
  REVOKEd from PUBLIC/anon/authenticated, GRANTed service_role. pg-real
  covers all of it.
- EB JWT minting moved to lib/connect/upstreams/enable-banking-jwt.ts (core
  must not import @/extensions/); the extension re-exports it, tests
  unchanged.
- lib/connect/hosted/{state,ledger,upstream-budget}.ts: HMAC-signed
  connector state (15-min TTL) so the consent redirect can use OUR
  registered EB callback and bounce back to the instance, no per-instance
  redirect URI at EB; the callback route gains that connector branch.
- app/api/connect/bank/[...path]: path allowlist (aspsps, auth, sessions,
  accounts/{uid}/{balances,transactions}), never open passthrough. POST
  /auth enforces the per-company connection quota + rewrites redirect/state;
  reads/deletes verify ledger ownership; every upstream call takes the
  global budget (429 + Retry-After when exhausted).
- issue-connector-key.ts: scopes default bank_sync,skatteverket (TIC out of
  v1), --bank/skv-connections-per-company + --sync-min-interval.
- Docs (SELF-HOSTING: bank connector live), DECISIONS.

Verified: 52 connect unit tests + 13 pg-real (run locally against
supabase/postgres with all migrations) + EB extension suite (225, jwt
relocation intact); full unit suite 15 979 green; tsc, guards, lint clean.
Not in this PR: SKV broker (PR5b) and instance wiring (PR6).

* feat(connect): Skatteverket broker + data proxy for self-hosted instances (tokens stay on the instance)

Sovereign plan WS3 PR5b, stacked on the bank proxy (#1751). A self-hosted
instance with a `skatteverket`-scoped connector key can now run the BankID
consent, file VAT/AGI and sync skattekonto through Arcim's registered
Skatteverket client; the SKV tokens are returned to the instance and stored
(encrypted) there.

- lib/connect/upstreams/skatteverket-oauth.ts: core-side SKV OAuth + data
  helpers (authorize URL, code/refresh exchange with Arcim's client secret,
  the four backing-API base URLs, the API-gateway Client_Id/Client_Secret
  headers). Core can't import @/extensions/, so this duplicates the
  extension's endpoints/scope set (one integrator = Arcim), mirroring the EB
  JWT relocation.
- app/api/connect/skv/oauth/authorize-url: builds the authorize URL against
  OUR registered redirect_uri + a signed connector state, per-company SKV
  connection quota, pending ledger row.
- app/api/connect/skv/oauth/token: exchanges/refreshes and RETURNS the tokens
  to the instance; the ledger keeps only sha256(access_token) +
  sha256(refresh_token).
- app/api/connect/skv/api/[...path]: allowlist over moms / skattekonto /
  agd-inlamning / agd-period. The instance sends the user's SKV Bearer (as
  X-Connector-Upstream-Authorization) + X-Connector-Key; the proxy checks the
  token hash against the ledger, adds Arcim's gateway credentials (never
  exposed to the instance), forwards. Same per-key + global budget as bank.
- The Skatteverket extension /callback gains the connector branch
  (isConnectorState -> 302 back to the instance; code never exchanged there).
- Docs (SELF-HOSTING: SKV connector live) + DECISIONS.

Tests: SKV oauth lib, authorize-url, token, data proxy, callback connector
branch (all green; 74 connect + 425 connect/SKV). tsc, guards, lint clean;
no-phantom-columns held at 380 (literal update branches). Not in this PR:
instance-side wiring (PR6).

Jakob WennbergandClaude Fable 5 335d908614 fix(domains,skatteverket): #1087 follow-ups: auth-path redirect exclusions, SKV callback hardening (#1094)
- Exclude auth/ and reset-password from the legacy-host redirect (#1092):
  email links sent before the cutover carry a PKCE code or recovery
  session whose cookies live on app.gnubok.se; forwarding them to the
  new domain breaks password resets and signup confirmations clicked
  after the flip. login/MFA stay redirected on purpose: a usable login
  page on the legacy host would establish sessions there and loop.
  Exclusion pattern extracted to lib/domains/legacy-redirect.ts with a
  unit test pinning the behavior.
- Clean up ephemeral oauth state rows (incl. oauth_user_id) when the
  SKV token exchange fails (#1090): identity data must not outlive the
  flow; best-effort so cleanup failure never masks the user-facing error.
- Assert the stored user is still a member of the company before the
  service-role storeTokens write (#1091): membership can be revoked
  between /authorize and the callback, and RLS no longer backstops the
  write. Checked before the exchange so the one-shot code is not burned.

Fixes #1090, fixes #1091, fixes #1092.

Jakob WennbergandClaude Fable 5 b420f3e1d9 feat(domains): dual-domain cutover to app.accounted.se (#1087)
* feat(domains): dual-domain cutover to app.accounted.se

The user-facing app moves to app.accounted.se while app.gnubok.se stays
alive for machine traffic (MCP connectors, API keys, third-party OAuth
callbacks, webhooks, crons), so no third-party callback registration is
on the critical path.

- next.config: host redirect app.gnubok.se -> NEXT_PUBLIC_APP_URL for
  page traffic only (/api, /.well-known, /_next excluded). Arms itself
  only once NEXT_PUBLIC_APP_URL leaves the legacy host, so merging this
  is inert and the cutover is a pure env flip + redeploy.
- skatteverket: redirect_uri pinned via NEXT_PUBLIC_SKV_OAUTH_BASE_URL
  (Utvecklarportalen registration is slow to change); the OAuth callback
  now resolves the flow from the state token + stored oauth_user_id via
  the service client instead of session cookies, which no longer exist
  on the OAuth host. Legacy same-domain flows fall back to the session.
- popup listeners (SkatteverketConnectPanel, AGIPanel) accept postMessage
  from the pinned OAuth origin; event.source identity check unchanged.
- /.well-known discovery docs reflect the allowlisted request host so
  existing MCP connectors on app.gnubok.se keep a self-consistent
  issuer/resource after the flip; spoofed hosts fall back to canonical.

* fix(review): recency-bound SKV state lookup, exact localhost match in discovery allowlist

- The oauth_state lookup now only considers rows updated in the last 10
  minutes: bounds how long a leaked/phished authorize URL stays
  completable, keeps the row set far below PostgREST's 1000-row cap, and
  surfaces query errors instead of misreporting them as CSRF.
- resolveDiscoveryBaseUrl matches localhost/127.0.0.1 exactly; the
  prefix check reflected spoofed hosts like localhost.evil.example.

* feat(mcp): kontoplan account tools + verifikat notes exposure

Two gaps reported by an MCP-driven user: no account management in the
API, and verifikat notes invisible to agents (they exist in the product
but MCP could neither read nor write them).

- add staged gnubok_create_account / gnubok_update_account (BAS 2026
  prefill for catalog numbers; rename/VAT-default/SRU/activate via
  update; both LOW risk reference data)
- add staged gnubok_set_voucher_note (notes-only annotation, legal on
  posted entries per the 20260608120000 trigger carve-out) and return
  entry_notes from gnubok_query_journal
- new pending_operations types create_account / update_account /
  set_voucher_note (CHECK migration + validate companion, applied to
  staging)
- tools/list payload ceiling 54K -> 56K (documented; wire contract,
  descriptions trimmed first)

* fix(skatteverket): unstick BankID connect flow and stale connection views

- respond to the OAuth callback immediately and run the post-connect
  refresh after the response (next/server after()): users no longer
  stare at Skatteverket's consumed consent page for up to 40s
- open the consent flow in a full tab instead of a 600x750 popup that
  hid the approve button below the fold
- disable connect buttons while the OAuth tab is open (parallel flows
  overwrote oauth_state + the PKCE verifier) and recover via a
  closed-tab watcher plus a delayed status refetch
- persist MISSING_SCOPE token health from the post-connect sync and
  show an actionable "approve all permissions" notice
- refetch connection state on tab visibility (settings connect panel,
  enable-banking panel, /skattekonto) so a connect completed in another
  tab or after a mobile app-switch shows up without a manual reload;
  fix /skattekonto never clearing its not-connected state
