Jakob Wennberg 12c59399ee fix(bokslut): remove uppskjuten skatt on obeskattade reserver in juridisk person (K3 29.37) (#1421)
* fix(bokslut): remove uppskjuten skatt on obeskattade reserver in juridisk person (K3 29.37) and confirm K3 to K2 reversion

In juridisk person K3 29.37 keeps obeskattade reserver at gross; the 79.4/20.6 split belongs to koncernredovisning. The old disposition double-counted the tax portion (result charged twice, 2240 overstated on top of gross 21xx). Removes the proposal step, POST kind, UI case, K2-to-K3 account seeding and the interim framework gate; keeps LATENT_TAX_DEFAULT_RATE for analytical soliditet presentation. Also adds the K3-to-K2 consequence confirmation dialog in settings.

* docs(decisions): scope the batch log to shipped code and record the 29.37 election nuance

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(settings): stop promising deferred-tax accounting the engine no longer does

The framework help text and the K2-to-K3 confirmation both told the user that switching to K3 means uppskjuten skatt is recognised separately on 2240/8940 with a 79.4/20.6 split. This PR removes exactly that behaviour, so the copy would have promised something the product does not do, which is the defect class this batch exists to remove. Both now describe what actually happens: kassaflodesanalys, komponentavskrivning and a wider note set, with obeskattade reserver carried gross per K3 29.37.

Mattsson 2c2743eb79 Check/salary bankid api (#892)
* fix(bankid): harden login/signup flow — polling, signup rollback, metadata merge, enrichment lookup

- middleware: read BankID enrichment from the bankid_enrichment table (the
  extension_data path has been dead since the multi-tenant refactor), so
  company-less BankID users land on /select-company instead of the manual wizard
- BankIdAuth: hard 6-min poll deadline; every failed poll counts toward the
  give-up limit; guard overlapping ticks so completion runs exactly once
  (a double /complete regenerated the magic link and invalidated the first,
  failing logins intermittently); retry clicks wait out the start cooldown
  instead of silently no-oping; Swedish messages for 429/unknown start errors
- bankid/complete: all-or-nothing signup — delete the created user when the
  identity insert, app_metadata update, or magic-link generation fails, so a
  retry starts clean instead of hitting account_exists with an unusable account
- bankid/unlink: read-merge-write app_metadata so has_password survives unlink
  (BankID-only users could otherwise strand themselves with no login method)
- login: BankID "create account" CTA now links to /register instead of
  dismissing the notice; sv.json: fix missing å/ä/ö in settings_bankid strings

* docs: move secondary guides into docs/, delete dead root files

Move DOCKER.md, SELF-HOSTING.md, WHITELABEL.md and extensions.md
(renamed EXTENSIONS.md) into a new docs/ folder and update all path
references (README, setup.sh, .dockerignore image rules, docker-publish
workflow comment, _example-branding, lib/branding/service.ts).

Delete two dead root files: customer.json (stray API-test payload) and
findings.md (point-in-time swarm audit export, criticals already filed).

* fix(api): security & correctness hardening + withRouteContext MFA migration across API routes

Audit of ~100 app/api routes. Highlights:

Security
- agent/conversations: list leaked colleagues' titles + message previews
  (company-scoped RLS, no user filter) -> user-scoped
- calendar/feed PUT: raw body into .update() allowed feed_token fixation on a
  public unauthenticated URL -> strict schema, content toggles only
- bokslutsdispositioner: unbounded schablonintaktRate could inflate the
  IL 30 kap 25% periodiseringsfond cap base -> bounded
- agent profile/composer/onboarding: viewers could rewrite the agent profile
  while sibling /verify blocked them -> role-gated

Correctness
- account-totals / listAssets: unbounded queries silently truncated at 1000
  rows (under-counted money; skipped assets at year-end depreciation) ->
  fetchAllRows with stable order (+3 more pagination fixes)
- voucher-gaps: swallowed detect_voucher_gaps RPC errors (BFNAR gap view could
  show "no gaps" when the check never ran) -> surfaced
- 5 phantom-success writes (OK on zero matched rows) fixed
- assets K3 component-sum validated against stale acquisition_cost -> fixed
- invite silent email-send failure -> response carries email_sent;
  deadlines/calendar cast-then-check JSON crashes -> Zod

Convention
- ~44 legacy routes converted to withRouteContext (MFA); added Zod validation,
  corrected status codes, console.* -> lib/logger

Response shapes preserved for existing callers. ~110 new tests.

* feat(bookkeeping): save a booking as a reusable template from Bokför direkt

Add a "Spara som mall" action to the manual booking dialog so users can
capture a kontering they just worked out as a booking template — right
where they figured out how something should be booked.

- derive amount-parameterised template lines from the concrete booking
  (settlement = the non-VAT leg nearest the total, 26xx = a VAT line with
  its rate snapped to the nearest standard rate, the rest = business
  ratios; line labels come from the loaded BAS chart)
- extract the shared TemplateForm out of BookingTemplatesPanel so the
  booking dialog reuses the same editor, live preview and convertibility
  hints instead of duplicating them
- save via the existing POST /api/settings/booking-templates endpoint

* fix(bokslut): render arsredovisning RR/BR at ÅRL post level — no kontonummer

Bolagsverket rejected a user's filed årsredovisning with "Balansräkning
och resultaträkning ska inte innehålla kontonummer": the PDF built every
statement row as per-account "1930 Företagskonto" lines while the iXBRL
filing path already aggregated to statutory posts, so the two artifacts
diverged.

The PDF statements now derive from the same K2 risbs mapping the iXBRL
document uses (mapTrialBalancesToK2), via a new statement-rows.ts that
emits post-level rows in uppställningsform order for both the K2 and K3
templates. Also fixed along the way:

- Jämförelseår column (ÅRL 3:5 §) — previous-year trial balances now load
  and render; the old PDF had no comparatives at all.
- mapping.warnings (unmapped accounts, RR ≠ 2099, obalans, reclass
  nudges) flow into ArsredovisningData.warnings so the wizard flags a
  non-fileable document before download.
- Flerårsöversikt current/previous year overridden with the mapper's
  strict-3000–3799 Nettoomsattning, mirroring build-input's
  duplicate-fact rule, so the FB table ties to the RR.
- FB eget kapital-table is post-level and drops obeskattade reserver
  (never eget kapital); K3 equity-changes statement uses real prior-year
  opening balances with derived utdelning/nyemission residuals that tie
  the roll-forward exactly to booked UB.
- build-input dedupes warnings now that the PDF path runs the same
  mapping.

Regression test asserts no RR/BR label ever contains a four-digit
account number again.

* fix(reports): diagnose untransferred prior-year results behind balance-sheet differens

Prod incident (97 kr): a multi-year SIE migration lacked one year's
omforing av arets resultat; the residual corrupted every later derived
opening balance and Balansrakningen showed a bare "Differens: 97 kr"
with no explanation. Continuity checking cannot catch this failure mode
(prior-year UB and derived IB match per-account by construction) - the
invariant that actually breaks is per-year P&L = 0 for all non-latest
years.

- lib/reports/imbalance-diagnosis.ts: shared detector
  (findUntransferredResults + buildImbalanceDiagnosis)
- Balansrakning/Balansrapport attach imbalance_diagnosis when unbalanced,
  naming the exact culprit years; rendered in web views + PDF; MCP
  gnubok_get_balance_sheet inherits the field via spread
- SIE import: parse-time warning when a completed year's vouchers leave
  a P&L residual, plus a post-import DB walk surfacing culprits as
  warnings and structured details.untransferredResults; the Arcim
  migration workspace previously dropped result.warnings entirely and
  now renders them
- opening-balance/correct: pre-flight the company lock date and return
  409 OB_COMPANY_LOCK_DATE (retryable: false, lock date interpolated in
  the client message) instead of the retryable 500 that invited blind
  retries; catch-path maps a raced trigger rejection to the same code

Diagnosis runs only on unbalanced paths (zero cost when healthy) and
never fails the report or the import. No migration, nothing persisted.

* fix: production error remediation — FX rates, deadlines, log levels, correction relink

Batch of fixes for recurring Vercel runtime errors:

- Riksbanken FX rates: persistent read-through cache (exchange_rates
  table), one retry honoring Retry-After on 429/5xx, bounded ingest
  concurrency, and an honest fallback — most recent cached observation
  or null, never a hardcoded rate silently booked into amount_sek.
  Unrated transactions stay repairable via refresh-exchange-rate.
- Tax deadline regeneration inserts replacement rows before deleting
  the superseded set, so a failed insert no longer wipes a company's
  deadlines (the 23502 user_id regression did exactly that). Migration
  makes deadlines.user_id nullable for system-generated rows.
- Route wrappers + errorResponse log 4xx outcomes at warn so only
  genuine 5xx reach Vercel's runtime-error clustering; client-supplied
  /api/log telemetry demoted to warn as well.
- application/json documents (raw PSD2 responses archived per BFL)
  validate as parseable JSON with object/array root instead of always
  failing the magic-byte check.
- correctEntry surfaces document-relink failures to callers, and the
  BFL document-immutability trigger now allows relinking underlag from
  a reversed entry to its correction (migration + pg test).
- Middleware clears stale session cookies on /api requests too, using
  scope 'local' so cleanup doesn't re-trigger the failed token refresh.

* fix(skatteverket): persist token health and stop retrying dead consents

Terminal auth errors (SESSION_EXPIRED, REFRESH_EXHAUSTED, MISSING_SCOPE,
TOKEN_CORRUPTED) mark the token row needs_reconsent with the error code
and timestamp — SKV per-flow refresh tokens live 65 minutes, so once
expired nothing recovers without a fresh BankID consent. The AGI
kvittens and skattekonto sync crons skip flagged connections instead of
failing every night, and the settings panel prompts for re-consent
proactively. A successful reconnect resets the row to active.

* fix(banking): allocate distinct BAS ledger slots for PSD2 mirror accounts

A bank returning N same-currency accounts used to map them all onto the
currency default (1930/1932/1933/1934), tripping the UNIQUE
(company_id, ledger_account) constraint per-account — swallowed errors
left accounts silently unmirrored. allocatePsd2LedgerAccount now hands
out the currency default first, then free 1931–1959 sub-account slots,
skipping slots held by any existing row.

- Callback persists allocations to accounts_data so the picker pre-fills
  reality; reconnect reuses previously mirrored ledgers instead of
  re-deriving (a user remap to 1935 survives).
- Selection save resolves effective ledgers up front and rejects
  duplicates or cross-connection conflicts with a 400 instead of
  silently skipping the mirror.
- Bank error codes + psu_type are forwarded to the settings page for
  every OAuth error, keying the Handelsbanken corporate fullmakt
  guidance.

* fix(agent): stage exact journal lines on categorization previews

Categorization previews only carried debit/credit accounts, the GROSS
amount, and separate VAT rows — read together that looks like an
unbalanced 'gross on cost account + VAT debit' entry, and it misled
both users and agents into rejecting correct proposals. The MCP
preview and the pending-operation PATCH now materialize the exact
lines the commit executor will post (net cost line, VAT line, gross
bank line, SEK) via buildTransactionEntryLines, and PATCH re-derives
them from the new mapping instead of spreading stale staged lines.
ApprovalCard and /pending render the verifikat lines, falling back to
the legacy summary only for operations staged before this fix.

* feat(bookkeeping): prune unused imported accounts from the chart

SIE imports routinely bring in hundreds of accounts that were never
used and clutter the kontoplan. New account_usage_counts RPC (one
grouped query instead of a count per account) backs GET
/api/bookkeeping/accounts/usage, and POST /api/bookkeeping/accounts/prune
deletes zero-usage accounts — dry-run first, then an explicit account
list capped at 2000. Accounts with journal lines are skipped, never
deleted. The chart manager shows a usage column and a prune dialog
grouping custom accounts vs unused BAS-seeded ones.

* feat(api): carry dimensions through v1 invoice and supplier-invoice surfaces

Credit-note creation now copies default_dimensions and per-line
dimensions from the original, so the reversing journal entry nets
against the same dimension cells instead of dropping them. List/detail
responses expose the dimension fields, and the OpenAPI spec snapshot
follows.

* perf: batch serial Supabase round-trips on hot dashboard paths

Every dashboard render pays the layout's query chain, so serialized
awaits are direct wall-clock: the layout, chat conversation, invoice
detail, supplier detail, select-company, and agent-onboarding pages now
run their independent lookups in parallel batches, and
getCompanyCapabilities folds its disabled-config read into the same
round-trip. JournalEntryList hydrates the saved fiscal-year scope
optimistically instead of serializing the first entries fetch behind
the fiscal-periods request. The supplier detail page filters invoices
server-side via a new supplier_id query param instead of fetching the
whole company ledger, and the invoice editor (with its framer-motion
dependency) lazy-loads so it stops shipping with the invoice list
bundle.

* feat(salary): one-click runs, payslip delivery, payments settings, run cockpit

Salary P1 batch, driving the 20-click flow toward 3 clicks:

- One-click 'Starta lönekörning': POST /api/salary/runs accepts an
  empty body and resolves defaults server-side — period follows the
  latest non-corrected run, payment date from the new
  salary_pay_day setting, series from the per-source-type map. The
  separate /salary/runs/new page is gone.
- Run detail page rebuilt as a step-railed cockpit (progress rail,
  KPI cards, employee ledger, journal preview) on a deliberately
  wider canvas; components extracted to components/salary/run/.
- Payslip delivery: tokenized public payslip pages (/payslip/[token],
  backed by salary_payslip_links) plus per-employee email send with
  PDF — employees need no account, and the middleware exempts the
  route from auth redirects.
- Payments settings: salary pay day, default bank, and pain.001 vs
  Bankgirot Lön format with per-bank upload instructions and an LB
  sunset warning (banks retire LB during 2026).
- AGI panel: full submission status flows (stale drafts, signing
  links, kvittens polling, error reports); tax payment panel with
  skattekonto shortcut and mark-as-paid.
- Salary calendar bulk editing, employee benefits/tax-card polish,
  municipality tax-table lookup improvements.

messages/sv+en also carry the strings for the account-prune,
skatteverket-reconsent, and banking surfaces committed just before
this.

* chore: adopt Next 16 proxy.ts convention + repo housekeeping

- Rename middleware.ts to proxy.ts with the proxy() export (Next 16
  renamed the middleware convention; behavior unchanged).
- Exclude dev_docs/ from tsconfig so stray snippets in planning docs
  don't break the build type-check.
- Ratchet antipatterns-baseline down (raw-route-auth 165 → 119) to
  lock in the withRouteContext migration from 5cfd2b76.
- template-library uses roundOre() instead of inline rounding.
- database.md: drop account_balances from the key-tables list.

* fix(bookkeeping): robust service-role detection in correction document relink

relink_documents_to_correction() keyed its service-role branch on auth.role(),
which reads the singular request.jwt.claim.role GUC that PostgREST v10+ and the
pg-real harness no longer populate. Genuine service-role callers (pending-ops
executor / MCP approve) landed in the auth gate and could not relink underlag.
Read the role from the request.jwt.claims JSON directly, mirroring the canonical
link_voucher_rpcs_tenant_guard convention. Validated on staging.

Also: harden the salary run page's error paths (res.json().catch) against
non-JSON error bodies, and roll back the pg-real service-role case in finally so
an aborted transaction cannot poison a pooled connection for the next test.

* fix(documents): restore journal_entry_line_id link durability (BFL 7 kap)

Migration 20260704103000 rewrote enforce_document_journal_entry_immutability to
guard journal_entry_id but left journal_entry_line_id to the metadata trigger,
which exempts draft-linked docs -- and the entry-level trigger only fired on
UPDATE OF journal_entry_id, so a line-id-only UPDATE never invoked it at all.
That let a set journal_entry_line_id be cleared to NULL, breaking the "link
durable from first set" invariant (document-immutability.pg regression).

Widen the trigger to fire on journal_entry_line_id too and guard it with the
same uuid-durability rule as journal_entry_id (setting NULL -> uuid stays
allowed; clearing/re-pointing a set value is blocked, status-independent). The
correction-relink GUC path, which legitimately clears line_id when moving
underlag to the posted correction, stays exempt. Validated on staging.

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.

Mattsson 32d9978f1b Fix/chrome pdf preview csp (#572)
* feat: add option to exclude year-end closing entries in SIE export and related reports

* delete docs

* fix: allow Chrome's PDF viewer in verifikat document preview

The /api/documents/:id/inline route shipped with
`object-src 'none'` in its CSP, which blocked Chrome's built-in PDF
viewer (it renders inline PDFs via an internal <embed>). Users on
Chrome saw "Det här innehållet har blockerats" when expanding a PDF
attachment in the bookkeeping view; Firefox (PDF.js) and Edge (own
viewer) were unaffected, and JPGs worked because <img> isn't subject
to object-src.

Drops the CSP for this route to the minimum needed for embeddability:
`frame-ancestors 'self'`. X-Content-Type-Options: nosniff plus the
fixed Content-Type from the handler already block MIME confusion;
X-Frame-Options: SAMEORIGIN + frame-ancestors still block clickjacking.

* feat(auth): add webmail deep link to email confirmation screens

Mirrors Stripe's signup UX: after asking the user to verify their email,
detect their webmail provider from the domain and show a button that
opens the inbox in a new tab. Gmail gets a from:<sender> search
pre-populated; Outlook/Yahoo/iCloud/Proton open the inbox directly.
Unknown / custom domains fall back to the existing copy.

Sender address is configurable via NEXT_PUBLIC_BRANDING_AUTH_EMAIL_FROM
(default noreply@gnubok.se) so white-label installs can match their
Supabase Auth SMTP config.

* fix(auth): unblock first-time password set for BankID users with MFA

Supabase rejects updateUser({password}) and mfa.unenroll with "AAL2 session
is required" whenever a TOTP factor is enrolled. BankID magic-link logins
produce AAL1, and middleware skips MFA enforcement for bankid_linked users,
so they had no path to AAL2 — leaving them unable to set a backup password
or disable MFA without going through the email-recovery escape hatch.

- /api/account/password: branch on app_metadata.has_password. First-time set
  writes via service.auth.admin.updateUserById (no existing credential to
  protect, AAL2 guard does not apply). Change-password keeps the user-session
  updateUser so AAL2 still fires for credential rotation.
- /mfa/verify: accept a safeReturnTo query param and route there after
  successful verify, so step-up flows can land back where they came from.
- SecuritySettings: detect the AAL2 error from both change-password and
  mfa.unenroll and redirect through /mfa/verify?returnTo=/settings/account
  instead of toasting a dead-end error.

* Add tests and rounding utility for öre precision in bokslut calculations

- Implemented `roundOre` function for rounding SEK amounts to two decimal places, ensuring consistent monetary calculations.
- Introduced `ORE_TOLERANCE` constant for comparing rounded amounts, facilitating invariant checks in financial entries.
- Created comprehensive tests for `roundOre`, covering typical cases, edge cases, and idempotency.
- Added year-end invariants tests to verify database-level guarantees for closing entries, ensuring they balance to the öre and reject discrepancies.
- Developed end-to-end tests for the dispositions chain, validating the correctness of calculations across various scenarios.

* fix: update PDF rendering to remove Swish QR code generation and set default to disable Swish visibility

* fix: enhance security by rejecting data URIs in safeReturnTo function tests

* fix: improve rounding logic in roundOre function and add customer_type migration

* fix: add customer_type column to customers and enforce CHECK constraint

* feat: enhance account deletion process and update user notifications

* Add service client for onboarding completion check and update escape hatch visibility

* Enhance invite flow and email handling for company members

* Refactor company context and RLS policies for active company isolation

- Update `switchCompany` to remove unnecessary revalidation as client handles navigation.
- Revise `getActiveCompanyId` to prioritize `user_preferences` and validate against non-archived memberships.
- Modify `setActiveCompany` to ensure `user_preferences` is the authoritative source while maintaining cookie compatibility.
- Enhance middleware to resolve active company using `user_preferences` and fallback to first non-archived membership.
- Introduce new API route `/api/company/current` to fetch the active company ID for cross-tab synchronization.
- Implement `CompanyTabSync` component for real-time active company enforcement across tabs.
- Create migration for RLS policies to enforce single-active-company isolation using `current_active_company_id()`.

* feat: implement viewer role enforcement for write permissions

- Added `useCanWrite` hook to determine if the current user has write permissions based on their role in the active company.
- Updated various components (JournalEntryForm, CustomerForm, DeadlineForm, etc.) to disable write actions and show a lock icon with a tooltip for users without write permissions.
- Introduced `requireWritePermission` function to enforce write permissions at the API level, returning a 403 response for viewers.
- Created tests to verify the behavior of the viewer role and write permissions.
- Added database migration to enforce read-only access for viewers at the database level.
