* 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

- 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 9dbaebcc50 fix(invoices): ROT/RUT credit notes; verifikat amount sort, HTML underlag, source chip (#1523)
* feat(invoice-inbox): store HTML mails as underlag, expandable field editor

Body-only mails and .html attachments (including forwarded .eml bodies) no
longer dead-end as "Fel vid bearbetning": the mail body is wrapped into a
self-contained text/html document, stored through the normal upload/extract
pipeline, and extracted via a new HTML-to-text Bedrock path, so the mail
itself can serve as bookable underlag. Empty mails keep the error row,
unsupported types are still rejected, and webhook retries dedupe on
resend_email_id.

Mail HTML is attacker-controlled, so rendering is fully sandboxed: iframe
sandbox in the workspace preview and a CSP sandbox header on
/api/documents/:id/inline for text/html. The type is accepted only from the
email pipeline (EMAIL_ALLOWED_MIME_TYPES), never from manual upload.

The "Extraherade falt" rail gains an expand button opening a centered
dialog with the same autosaving field editor at a readable size (two
columns), which also gives every failed or skipped extraction a manual
fallback.

* feat(bookkeeping): sortable verifikat list headers with amount sort

- clickable sort toggles on the verifikat list headers (asc -> desc -> default)
- total_amount computed column + sort_by total/description on the list route
- failed list loads render an error card with retry, never the empty-ledger state

* fix(import): decode bank CSV as Windows-1252 fallback in column mapping

The client read the uploaded file with file.text(), which is UTF-8-only,
so Windows-1252 exports (e.g. Handelsbanken) rendered and re-parsed with
U+FFFD in place of Swedish characters. Decode from bytes with the shared
decodeFileContent() helper, matching what the server parse route does.

* feat(bookkeeping): stackable sort keys on verifikat list headers

- shift-click adds a column as secondary/tertiary sort key (max 3), plain
  click keeps the single-key tri-state cycle
- sort_by accepts a comma-separated priority list; single tokens stay valid
- voucher tiebreak follows the last key's direction (#972 parity)
- priority numbers on stacked headers; hint text in the filter dialog

* fix(invoices): keep ROT/RUT deduction fields positive on credit notes

Crediting an invoice with a ROT/RUT deduction failed 100% of the time:
the credit-note path negated deduction_total (and per-item
deduction_amount) like the other amounts, but both columns carry
CHECK (>= 0), so Postgres rejected the insert and the user only saw
'Kunde inte skapa kreditfaktura'.

Store the deduction fields as positive magnitudes, matching the
convention everywhere else. The stored sign is inert on credit notes:
the reversing verifikat recomputes the ROT/RUT split from the items,
and the PDF and amount-to-pay logic skip deductions on credit notes.

* refactor(transactions): share the source chip across inbox and history modes

Move SourceFilter to transaction-types.ts (widened with 'bank:other' and
'acct:<id>'), render the one toolbar ContextPicker in both view modes,
and drop the narrower duplicate chip inside TransactionHistoryList. The
history list now applies the acct:/bank:other narrowing itself and hides
skattekonto rows under any bank-side selection.

* test(schema): recognize PostgREST computed columns in the migration parser

The verifikat amount sort orders by total_amount, a PostgREST computed
column (a function on the journal_entries row type, migration
20260811100000). The schema guard only modeled real columns, so
no-phantom-columns flagged the order as a phantom.

Teach the parser that a function whose only argument is a table's row
type joins that table's column set, with DROP FUNCTION retraction when
the signature names the row type.

* fix: resolve PR #1523 review findings

- journal-entries route: append the globally unique id tiebreak to every
  direct-query sort; voucher series+number repeat across fiscal years, so
  the all-years scope could duplicate or drop rows at page boundaries.
  Existing order assertions updated, new all-years tiebreak test.
- documents inline route: CSP source policy on HTML previews; sandbox
  alone still loads remote resources, letting a tracking pixel notify the
  sender on open. New route test asserts the full header.
- JournalEntryList: catch rejected list requests so loading cannot stick
  forever, and gate every post-await state write behind a request
  generation so a slow earlier request cannot overwrite the current sort.
- TransactionHistoryList: pagination follows the selected source scope
  (reachable with zero matches on the current page, hidden for the
  skattekonto scope it cannot affect).
- transactions page: bank:other picker availability derives from history
  rows too, not only the pending inbox dataset.
- DECISIONS.md: mark the superseded single-sort decision; record the
  credit-note deduction positive-magnitude invariant and its verified
  reader inventory (Swedish review flag).

* fix: guard metadata refetches behind the list request generation

fetchAttachmentCounts and fetchRattelseFlags write state after their own
awaits; a stale list request's late completion could overwrite attachment
counts and rattelse flags for rows a newer request just rendered, showing
false missing-underlag warnings. Both helpers now take the caller's
generation guard and discard stale completions, including the
attachment-counts loaded flag.

Jakob Wennberg b4a21b1029 fix(documents): RFC 5987 Content-Disposition so NFD filenames stop crashing inline view (#964)
* fix(documents): RFC 5987 Content-Disposition so NFD filenames stop crashing inline view

macOS/iOS uploads carry NFD-decomposed filenames (base letter + combining
diaeresis U+0308, char code 776). undici Headers require ByteString values
(every code unit <= 0xFF), so splicing the raw filename into the
Content-Disposition header threw while building the response and the
inline document route 500ed. 122 prod documents across 35 companies hit
this; last crash 2026-07-09T16:17.

Add lib/api/content-disposition.ts emitting the RFC 6266 dual form:
an ASCII quoted fallback (NFC-normalize, then replace anything outside
printable ASCII plus quote and backslash with _) and
filename*=UTF-8''<percent-encoded> per RFC 5987 (encodeURIComponent on
the NFC name, additionally escaping ! ' ( ) * which it leaves bare).

Use it in the inline document route and in the two latent same-shape
sites that embed raw employee names in payslip PDF headers.

* fix(api): sanitize lone surrogates before percent-encoding Content-Disposition (CodeRabbit)

Unpaired UTF-16 surrogates survive normalize('NFC') and make encodeURIComponent throw a URIError, so replace them with U+FFFD via String.prototype.toWellFormed() before encoding so the helper always returns a valid header value.

Jakob Wennberg ec27228a8e style: remove em/en dashes repo-wide, add CLAUDE.md rule against them (#890)
Em dashes (—) and en dashes (–) had spread across comments, docs, tests,
and a few UI strings, reading as AI-generated boilerplate rather than
house style. Replaced each with punctuation matching its context: colon
for explanatory clauses, comma for asides, plain hyphen for numeric/legal
ranges (e.g. "21-23§"), "to"/"till" for date ranges, parentheses for
paired-dash asides. messages/en.json and messages/sv.json were fixed by
hand together to keep sv/en in sync.

Left untouched where the dash is the functional subject rather than
decorative punctuation: date-range-parser.ts's separator regex,
charset-repair.ts's CP1252 byte-mapping table (and its test), the SIE
encoding mojibake docs, generic-csv.ts's minus-sign normalizer, the
agent system-prompt files that already instruct against em dashes, and
a golden iXBRL test fixture compared byte-for-byte.

Also fixes two bugs surfaced along the way: an off-by-one in
ApiKeysPanel's scope-label split (a leftover from an earlier partial
pass), and a charset-repair test that had lost the literal en-dash it
exists to verify.

Regenerated the agent atom seed migration (skills:generate) since 27
SKILL.md files changed. Added a CLAUDE.md rule against em/en dashes,
with an explicit carve-out for the functional-dash cases above.

* fix(documents): harden PDF preview and upload validation

- JournalEntryAttachments: switch inline PDF preview from <iframe> to
  <object type="application/pdf">. Mirrors the AttachmentPreviewSheet
  fix from #572 — Chrome's frame pipeline intermittently surfaced
  "Det här innehållet har blockerats" on iframes even with permissive
  CSP. <object> invokes the PDF plugin directly. crbug.com/271452.

- /api/documents/:id/inline: resolve Content-Type via file extension
  when mime_type is null or application/octet-stream. Legacy uploads
  landed with empty File.type from some drag sources; combined with
  the new X-Content-Type-Options: nosniff header on this route,
  Chrome refused to render valid PDFs. Extension fallback covers
  every legacy row without a DB backfill.

- /api/documents POST: surface DB-trigger period-lock errors as a
  400 DOC_UPLOAD_PERIOD_LOCKED with a Swedish reason. Previously
  every catch was bucketed into DOC_UPLOAD_STORAGE_FAILED (500 /
  "Filen kunde inte sparas") which hid the real cause from users
  attaching to verifikationer in closed/locked fiscal periods.

- document-service: add validateDocumentMagicBytes() that inspects
  the first bytes for valid PDF/PNG/JPEG/WebP headers (PDF tolerates
  a leading UTF-8 BOM). Wired into uploadDocument() and
  createNewVersion() so every upload path is protected — UI, MCP,
  and future email/webhook ingestion. Defends against agents that
  send a base64-encoded text placeholder instead of real binary
  bytes via the gnubok_upload_document MCP tool, which produced
  tiny (15-561 byte) "PDFs" that failed to render in Chrome and
  in external viewers.

Tests use a minimal valid PDF buffer (%PDF-1.4 … %%EOF).

* feat(arsredovisning): emit ÅRL-required notes and FTE-weighted medelantal

Five compliance gaps fixed in the K2 and K3 noter builders:

- Anläggningstillgångar roll-forward per ÅRL 5:8 § — per-category IB
  anskaffningsvärde, tillkommande, avgående, UB and accumulated
  avskrivningar movement (was only emitting avskrivningstider).
- Långfristiga skulder förfallande efter mer än fem år per ÅRL 5:13 §.
- Ställda säkerheter and Eventualförpliktelser as separate notes per
  ÅRL 5:14-15 § (K2 previously combined them).
- Koncernförhållanden per BFNAR 2016:10 kap. 19 / BFNAR 2012:1 kap. 8.

Replaces medelantal anställda — the old query filtered employees by an
is_active column that doesn't exist, so the note never emitted. Now
uses an FTE-weighted day-based average per ÅRL 5:20 §.

Six disclosure fields persist on arsredovisning_narratives as per-period
overrides; the UI extends the existing förvaltningsberättelse editor
with a "Lagstadgade upplysningar" subsection sharing the same Spara
button — no new pages, no settings changes.

* fix(invoices): respect vat_registered=false and hide personnummer for B2C

- PDF address block no longer prints org_number for individual customers
  (GDPR data minimization; ML 17 kap 24§ requires name + address only).
- Wire company_settings.vat_registered through the rule helpers, invoice

  registered seller cannot charge VAT (ML 1 kap. 1§). The PDF suppresses
  the empty "Moms 0%" row and shows a dedicated "Företaget är inte
  momsregistrerat" notice instead of the ML 3 kap. exempt notice.
- Engine unchanged: 'exempt' treatment already routes to 3004/3100 and
