Mattsson 4f6ecad549 feat(white-label): invite-only signup for brand domains (#1995) 
* feat(white-label): invite-only signup for brand domains

A brand domain belongs to the partner's people (founder decision
2026-08-27): only allowlisted or invited users may create an account on
an invite-only brand domain; everyone else is shown an interstitial that
sends them to the canonical Accounted signup.

- brands.signup_mode ('open' default / 'invite_only') +
  brand_signup_allowlist (lowercase emails, team-scoped RLS, owner/admin
  writes) + create_company_for_brand_signup RPC, with pg-real coverage
- server-side gate (lib/auth/brand-signup-gate.ts) enforced on every
  signup path: email signup moved to POST /api/auth/signup (the browser
  used to call GoTrue directly, so a client-side check would be
  bypassable), BankID gated in /bankid/complete, Google covered by the
  dashboard layout's brand-domain bounce
- company invites bypass the allowlist: the invite is the authorization
- register page interstitial on gated brands (no email in the outbound
  URL), sv+en strings
- dashboard layout bounces non-belonging sessions off gated brand hosts
  to the canonical domain (navigation rule like WL-01, not a security
  boundary)
- allowlisted signups' onboarding-created companies attach to the
  brand's byra team via the new RPC, so WL-01 homes them on the brand
  domain; the allowlist entry recorded by an owner/admin stands in for
  the WL-15 admin gate
- byra cockpit page /clients/access + /api/clients/signup-access to
  manage the mode and the allowlist

All existing brands default to 'open': behavior is byte-identical until
a brand is flipped to invite_only.

* fix(white-label): rollback brand-signup company with the service client

Skeptic (correctness) found that a brand-signup company created under the
service role rolled back with the cookie-session client: `companies` has
RLS and no FOR DELETE policy, so the delete was a silent 0-row no-op,
stranding a member-less ghost company on the partner's byra team. Pass an
optional rollbackClient to createCompanyCore and hand it the service
client on that path; user_preferences.active_company_id then clears itself
via its ON DELETE SET NULL FK once the company row is actually deleted.

Also map a validateBody 400 (flat envelope, no code) on the register page
to the specific email-invalid field message instead of the generic one,
since the client already pre-gates password strength.

* fix(white-label): fail-safe brand lookup, pg-test seed, anonymize fixtures

Second resolve-pr cycle: skeptic + CodeRabbit findings and a green-up.

- Fail safe on a brands-table error (CodeRabbit CWE-285): the gate treated a
  failed resolveBrandByHost as an unbranded host, opening invite-only signup
  during a transient DB blip. resolveBrandResultByHost now distinguishes
  "no brand" from "lookup failed"; the gate returns lookupFailed and the
  email + BankID routes answer 503 (retry), never creating an account.
- pg-real: the RLS delete test seeded its row inside withUserContext, which
  always rolls back, so the owner DELETE saw zero rows. Seed on the superuser
  pool instead.
- Anonymize every test/fixture brand to the repo's existing synthetic
  placeholder (Siffra / app.siffra.se): no real partner names in code.
- SignupAccessManager: functional setData updates so a concurrent mode
  toggle and an add/remove do not clobber each other's snapshot (CodeRabbit).
- Route a transient-error message through i18n instead of the raw envelope
  (raw-user-error guard); new register.error_temporary sv+en.

* test(white-label): anonymize new signup-gate fixtures; log oracle residual

Rename the placeholder brand in the four new brand-signup test files to a
clearly-fake, partner-unrelated name (Testbrand / app.testbrand.example);
the previous placeholder echoed a real partner. Scoped to files this PR
creates; the repo-wide legacy placeholder is left for a separate cleanup.

Also record in DECISIONS.md that the feature ships accepting the
low-severity allowlist-enumeration residual (captcha-free 403 vs 200 on
the signup endpoint), with rate-limiting as the follow-up option.

Mattsson fdb5f6f891 feat(white-label): byra white-label infrastructure: brands, cockpit, home domains, branded email (#1956) 
* feat(white-label): brand and team-kind foundation

- brands table: one white-label identity per byra team (unique mutable
  domain, row presence = live, email sender identity, hex color CHECKs)
- teams.kind ('personal'|'byra'): ops-only kind changes, deterministic
  ensure_user_team (personal team only), AFTER UPDATE role re-sync so a
  demoted consultant loses admin in client books immediately
- resolveBrandByHost/resolveBrandForCompany with 60s TTL cache, derived
  chrome tone and WCAG contrast gate; no brand row = default appearance

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

* feat(white-label): per-request brand theming, wordmark slot and source footer

- root layout resolves the brand from the Host header and injects a
  server-rendered style block (light + dark), font pair classes and a
  BrandProvider/useBranding context; default hosts render byte-identically
- BrandWordmark logo slot, host-aware manifest and favicon,
  images.remotePatterns for Supabase Storage logos
- curated font menu mechanism (font_key -> variable pair, preload:false
  for non-default entries)
- AGPL source-code footer link on login and public pages, both brands

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

* feat(white-label): byra team invites, member management and team billing

- team invites unfrozen behind a kind gate (byra teams only, owner/admin
  invite); members route handles multi-team membership; members/[id]
  unfrozen with last-owner protection; invite management UI in settings
- billing/status learns team-scoped grants and the settings page shows a
  read-only "part of the byra agreement" state instead of the upgrade pitch
- 30-day trial suppressed for companies created under a byra team

* feat(white-label): brand-aware outbound mail, auth email hook and public invoice branding

- every outbound mail is sent in the brand of the company it concerns:
  getSenderForCompany/getBaseUrlForCompany chain (verified brand domain,
  "via Accounted" fallback, canonical default) wired into invites,
  payslips, invoice deliveries and reminders
- Supabase Send Email hook endpoint (signature-verified with node:crypto,
  dormant until configured) renders auth mail per brand via redirect origin
- public invoice pages carry the company's brand mark
- snapshot suite per template class guards against wrong-brand mail

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

* feat(white-label): byra cockpit, home-domain rule and tab guard

- Klienter route: five urgency-sorted columns (company, unbooked, inbox,
  next deadline via the status engine, last booked) for byra team members,
  who land there after login on their home domain
- soft switch straight into a client and back; blocking two-exit tab
  guard against writes to the wrong active company
- client company creation admin-gated at the DB level (a created company
  is +1 on the byra invoice), bound to the byra team, no trial
- home-domain rule in the UI: switcher partitions companies by host,
  signpost page for companies homed elsewhere

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

* feat(white-label): brand-aware app name across UI strings

- 24 message keys per locale converted to the {appName} ICU parameter,
  27 call sites pass the active brand name (useBranding client-side,
  getRequestAppName server-side)
- 6 hardcoded JSX literals swept; statutory filing and API identity
  surfaces deliberately keep the Accounted name
- 34 new i18n keys for the cockpit, team invites, billing state, tab
  guard, signpost and source footer (sv/en parity verified)

  home domain, signpost, umbrella subdomain, brand color, cockpit)
- DECISIONS.md entries from the build waves

* feat(white-label): lean byra cockpit sidebar with company-mode back link

Byra team members now get a two-mode sidebar: on cockpit routes (/clients
and the new /byra pages) only Hem, Klienter, Automationer and Nyckeltal
show; entering a client company brings back the full company sidebar with
a pinned back-to-clients link (expanded, rail and mobile). New pages: /byra
home with client count, needs-action count and per-client urgent deadlines
reusing the fetchClientOverview aggregation, plus designed empty states for
/byra/automations and /byra/kpi. Signpost gate allows the byra routes;
non-byra users are unaffected.

* fix(white-label): cockpit shows no active company and keeps lean sidebar under settings

In cockpit mode the bottom user widget no longer shows the active company
subline or the company-switcher flyout: the cockpit sits above the
companies and clients are entered through the Klienter list. The settings
modal previously flipped the sidebar to the full company nav behind it
because the pathname becomes /settings/*; the sidebar now keeps the mode
of the surface underneath.

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

* fix(white-label): keep company picker in cockpit with nothing selected

The cockpit user menu gets the company-switcher flyout back, but neutral:
the row reads "Valj bolag", no company carries the check mark or active
styling, and picking any company (including the technically-active one)
enters it with a full navigation. Company mode is unchanged.

* chore(db): renumber white-label migrations past main and add byra settings scope

Renumber 20260801100000-120000 to 20260804110000-113000: main already
carries applied versions up to 20260803231000, and Supabase branching
refuses local migrations stamped before the remote head (the repo rule
from 5932632f5: keep new versions strictly newest). Comment references
updated in the pg tests, route docs and onboarding precheck.

Also ships the byra settings scope: settings opened from the cockpit
(?ctx=byra, honored only for byra team members) show account-level
sections only (Konto, Medlemmar och roller), hide company-scoped
sections and the company kicker, and the team section is registered in
SETTINGS_SECTIONS so Medlemmar och roller renders inside the settings
window. The cockpit user menu drops Abonnemang and carries the scope on
its links; section switches preserve it.

* feat(byra): cross-client nyckeltal view in the cockpit

Period presets and company chips in the URL, summary tiles, merged
monthly income/expense chart and a sortable per-client KPI table.
Numbers come from the existing get_kpi_report_aggregates RPC per
client (no new migrations); calendar months are the cross-client
axis since clients can have different fiscal years.

* feat(white-label): byra self-service brand logo and app name

New Varumarke settings section (byra scope, owner/admin): logo
upload/remove and an editable app name; domain stays read-only.
brands has no write RLS by design, so writes go through
/api/byra/brand routes with the service client behind an explicit
owner/admin team check. Files land in logos/byra/{teamId}/. The
expanded sidebar shows the brand app name beside the logo.

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

* fix(white-label): route root layout through the shared brand resolver

app/layout.tsx carried a private copy of resolveRequestBrand, so it
and lib/branding/request-brand.ts could drift. The layout now uses
the shared function, which also gains a BRAND_DEV_DOMAIN override:
on literal localhost hosts only, resolve that brand so branding is
testable in local dev. Real domains are unaffected even if the
variable leaks into a deployment.

* feat(byra): automations roadmap teaser and cockpit i18n strings

The Automationer tab now previews the planned automation set
(Monday briefing, deadline watch, rule-driven bookkeeping,
connection watch, monthly checklist, report delivery) instead of a
bare empty state. Bundles the sv/en strings for the whole cockpit
wave (nyckeltal, varumarke, automations) and the decision-log
entries.

* feat(white-label): byra owners/admins land in the cockpit, not an auto-picked company

After login "/" resolved the first-membership fallback and opened a client
company nobody chose, and the top-left brand mark always linked back to it.
Byra owners/admins now home to /byra: the logo links there always, and "/"
redirects there unless a company was explicitly picked this browser session.

The middleware writes the fallback company back to user_preferences, so the
DB cannot tell picked from auto-picked; setActiveCompany stamps a session
cookie (gnubok-company-picked) on every explicit switch instead. The byra
check on "/" reuses the layout's team_members query via a request-cached
helper, so it costs no extra round trip. Byra members and regular users are
unchanged.

* refactor(white-label): drop brand color theming, keep monochrome everywhere

White-label is logo + app name + domain only (founder call): the
layout no longer injects brand color CSS variables, stamps
data-brand or colors the browser chrome. buildBrandVarsCss, its
WCAG gate and the brand_color/chrome_color columns stay dormant
for a future opt-in.

* fix(db): arm SIE RPC statement_timeout via pgrst.db_pre_request hook

ALTER FUNCTION ... SET statement_timeout (20260629160100, 20260721144311)
never re-arms the running statement's timer, so large SIE imports still
died at the role default 8s. The pre-request hook runs as its own
statement before the main query, so set_config there is what the main
statement's timer is armed with. Scoped by request path to the three SIE
RPCs; every other request keeps 8s.

* fix(byra): drop the 'what's coming' tail from the automations intro

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

* feat(white-label): byra owners/admins with zero companies land in the empty cockpit

Both no-company gates (Edge middleware and the dashboard layout) sent
every company-less user to the onboarding wizard, which forced a fresh
byra owner to create a personal company before ever seeing the cockpit.
Byra owners/admins now pass through to cockpit routes (/byra, /clients,
/companies/new, /settings, /api) and are steered to /byra elsewhere.
Plain byra members and regular users keep the onboarding redirect.
The membership lookup runs only in the rare no-company state, so the
middleware hot path is untouched.

* fix(white-label): auth wordmark shows the brand logo alone

Byra logos usually carry their own name, so logo + app name text on the
login/register hero read as a duplicate. Branded hosts with an uploaded
logo now render the logo only, with the app name as the image's alt
text. Hosts without a logo keep the text wordmark unchanged.

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

* feat(white-label): per-brand favicon via brands.favicon_url

Branded hosts used logo_url as the tab icon, which squashes wide byra
lockups at 16px. New optional brands.favicon_url holds a square mark;
the root layout prefers it and falls back to logo_url as before.
Migration applied to staging (idempotent DDL).

* fix(auth): wire the villkor and integritetspolicy footer links

Both auth pages shipped with href="#" placeholders. Villkor now points
at the platform terms on the marketing site (accounted.se/terms; the
terms are the platform's even on branded byra hosts) and
integritetspolicy at the in-app /privacy page, host-relative so it
resolves on every branded domain. Both open in a new tab so the auth
form state survives.

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

* fix(settings): styled popup for the team role dropdowns

The byra team panel's role pickers (member rows + invite form) were
native selects, so the opened list rendered as the unstylable OS menu.
Swapped to the Radix Select with the popup styled like every other
overlay; the trigger keeps the flat quiet SettingsSelect look.

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

* fix(email): branded sender shows the brand name alone, no via-platform

Byra invite mail read "Willem via Accounted" in the From display name.
The tier-2 fallback (brand on the platform address) now renders just the
brand name; the platform stays visible in the actual From address until
the brand verifies its own sender domain (tier 1, unchanged).

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

* fix(white-label): byra landing applies to every team member, not only owners/admins

An invited byra consultant (role member) still landed in an auto-picked
client company after signup. The cockpit landing rules ("/" redirect,
brand-mark home link, and both no-company gates) now key on byra team
MEMBERSHIP instead of the owner/admin role: anyone with cockpit access
homes to /byra. Regular users unchanged.

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

* fix(email): branded team invite names the byra, not "ett team pa <platform>"

Subject, headline, body and text variant now read "Du har blivit
inbjuden till <Byra>" (brand casing kept) when the team has a brand.
Brandless teams keep the platform phrasing byte-identical.

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

* fix(white-label): sidebar keeps cockpit mode after refresh on settings

The sidebar's cockpit/company decision on /settings/* rested on React
state remembering the surface underneath, which a hard reload wipes: a
byra user refreshing settings opened from the cockpit got the full
company nav and read it as landing in a client company. The ?ctx=byra
marker already in the URL survives reloads, so the sidebar now honors
it as the cockpit signal alongside the in-session memory.

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

* fix(white-label): hide the active-company chip in byra-scoped settings

The full-page settings header (the hard-refresh fallback surface) showed
the ActiveCompanyBadge even under ?ctx=byra, so a byra user read the
auto-active client as "the company I am in". The chip now follows the
same byra-scope rule as the modal's kicker.

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

* fix(white-label): tab guard no longer fires in the tab that initiated the switch

BroadcastChannel delivers the company-switch broadcast to every listener in
the same tab too, so the cockpit tab raised its own WL-09 "switched in
another tab" dialog over the hard navigation into the clicked client.
performCompanySwitch now marks the switch as self-initiated; CompanyTabSync
suppresses only the dialog for that observation (stray writes still get
their 409) and clears the marker on bfcache restore so back-navigation
regains the full guard.

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

* fix(settings): styled popups for every settings dropdown

SettingsSelect rendered a native <select>, whose OS listbox cannot be
styled and clashes with the panel (same problem the team-panel role
dropdowns had). It now renders through Radix Select with the flat
dashed-underline trigger, keeping the native prop surface so all 13 call
sites work unchanged: value/defaultValue, onChange(e.target.value),
<option> children, and a hidden input that carries `name` into
SettingsFormWrapper's FormData read and raises the bubbling input event
its dirty tracking listens for. Empty-string option values map onto a
sentinel at the Radix boundary. The backup form's boxed fiscal-year
select moves to the shadcn Select with a placeholder.

* feat(white-label): home-domain affinity redirect in middleware

Every signed-in user now homes on a domain: byra team members on their
brand's domain, everyone else on the platform app URL, except a byra's
client users, whose home is the byra domain their companies live under.
On any other product host the request redirects to the home domain's
root, where the user meets the RIGHT branded login (sessions are
per-domain by design). localhost, direct *.vercel.app hosts and IP
hosts are exempt; a 15-minute host-scoped cookie caches the "this is
home" verdict so the hot path costs zero extra queries; lookup failures
fail open. Complements the WL-01 signpost, which keeps handling
per-company homing inside a domain.

* feat(white-label): shareable invite link and re-send for byra team invites

A failed invite mail previously surfaced only as a toast description while
the invitation quietly waited for a mail that never arrived (the Arbore
case). The inviter now always has a recovery path:

- persistent share-link line after invite create/re-send: ochre attn line
  with a copy action when the mail did not go out, quiet muted line with
  the same action when it did
- POST /api/team/invite/[id] re-sends a pending invitation with a fresh
  token and expiry (same byra-only owner/admin gates as DELETE)
- brand mail sending extracted to lib/email/send-team-invite.ts, shared
  by create and re-send so the two paths cannot drift

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

* fix(white-label): sidebar shows uploaded brand logo alone, no app-name label

Byra logos usually carry their own name, so logo + text in the expanded
sidebar read as a duplicate (same founder call as BrandWordmark,
2026-08-05). The app-name label now renders only for branded hosts
without an uploaded logo.

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

* fix(white-label): close the four skeptic refutations before merge

- trial seed: migration 130300 now carries the seven-key PAID body from
  20260818170000 plus the byra guard, instead of silently reverting it;
  pg test pins the full key set against PAID_CAPABILITIES
- byra gate: new migration 130600 adds the owner/admin gate to
  create_company_for_user (v1 API + MCP path), and both surfaces resolve
  the default team personal-only, so a consultant's private company can
  never attach to the byra team
- home-domain: byra staff who also have canonical-homed companies are no
  longer redirected off the platform host; the signpost handles per-company
  homing (5 new middleware tests)
- settings selects: the Radix popup renders optgroup group headers again
  (ROT/RUT work-type picker)

* fix(white-label): pg-real rollback-safe assertions and deep-link-preserving affinity redirect

The byra company-creation pg test asserted persisted rows through the pool
after withUserContext, which always rolls back its transaction; the
assertions now run inside the transaction after RESET ROLE. The home-domain
affinity redirect carries the original path and query across the domain hop
(PR Agent finding), so invite links and deep links survive the correction.

Mattsson 11995b1b0c feat(auth): make automatic logout an opt-in per-user setting (#1536) 
* feat(auth): make automatic logout an opt-in per-user setting

Session timeouts (30 min idle / 12 h absolute on hosted) now apply only
to users who enable "Automatic logout" in Settings > Security. Default
is off: sessions live for the full Supabase refresh-token lifetime, the
behavior from before the 2026-07 session hardening.

- user_preferences.auto_logout (migration, default false), toggled via
  the extended /api/user/preferences route
- The opt-in is snapshotted into the signed timeout cookie at mint, so
  enforcement stays DB-read-free per request; the preferences route
  clears the cookie on change so a toggle takes effect immediately
- Pre-toggle cookies are authentic-but-stale: re-minted preserving
  their timers, never routed down the tamper path, so the rollout does
  not log anyone out
- NEXT_PUBLIC_SESSION_TIMEOUT_FORCE_ALL=true enforces timeouts for
  every user regardless of preference (emergency lever, also plumbed
  through the Docker image); self-hosted stays disabled by default

* fix(auth): resolve PR #1536 review findings

- Replace the spread upsert in /api/user/preferences with one literal
  payload per field: the phantom-column schema guard cannot resolve
  spread payloads (Unit tests 3/4 ceiling failure)
- Map the preferences 500 through getErrorMessage so the user-facing
  text is Swedish (CodeRabbit)
- fetchAutoLogoutPreference now returns null on a FAILED read instead
  of a fail-open false: callers skip minting so an unknown preference
  is never persisted into the year-long signed cookie, and the next
  request retries; failures log at error level, distinct from the
  normal opt-out path (compliance swarm GDPR Art.32(1)(b) / ISO A.8.5)

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

* fix(auth): write multi-field preference updates as one atomic upsert

A request carrying both hide_assistant_fab and auto_logout previously
issued two sequential writes, so a failure of the second returned 500
after half the request had persisted (CodeRabbit, PR #1536). One
literal upsert per accepted field combination keeps the write atomic
and stays resolvable for the phantom-column schema guard.

Mattsson 1c9d378df8 feat(auth): enforce session idle and absolute timeouts (#1387) 
* feat(auth): enforce session idle and absolute timeouts

Hosted browser sessions now carry an HMAC-signed, HttpOnly cookie holding
session start, last activity and sign-in method, bound to the Supabase
session. Middleware enforces a 30 min idle and 12 h absolute limit
(reason-coded redirects to /login), a heartbeat route advances idle
activity from real user input, and a client controller warns 2 minutes
before expiry. BankID users are routed back to BankID on re-auth via a
short-lived method hint. API-key and MCP bearer surfaces are exempt;
self-hosted installs default off and can opt in via env vars.

* fix(auth): derive session-timeout signing key via HKDF

* fix(auth): address session-timeout review findings

- signSessionTimeoutState returns null on signing failure instead of
  throwing, so a missing secret degrades the timeout feature in line
  with verifySessionTimeoutState rather than crashing authenticated
  requests; middleware and heartbeat skip the cookie write when null
- heartbeat initializes a fresh signed state for a missing or
  session-mismatched cookie, mirroring middleware, instead of
  returning SESSION_EXPIRED during normal initialization
- sessionStateMatchesUser treats an unresolved current session id as
  a mismatch for session-bound state so another session's cookie is
  never accepted on the userId fallback alone
- drop aria-live from the countdown DialogDescription so screen
  readers are not interrupted every second
