* fix: surface active TIC companies + block duplicate org numbers
Three fixes from live-prod testing:
1. Enrichment filter hid the user's directorships. Now accepts both
Completed and PartiallyCompleted status from TIC (tenants without
CompanyRoles enabled still get SPAR) and the /select-company role
filter no longer requires companyStatus === 'Aktivt' — real TIC
payloads have been observed with different values, and positionEnd
alone is the authoritative "currently a director" signal. Added
PII-free diagnostic logs so the next shape-mismatch is debuggable
from Vercel logs without a round trip.
2. Manual wizard silently allowed duplicate org numbers. Added:
- findExistingCompanyByOrgNumber helper in actions.ts (service role,
bypasses RLS to see cross-tenant rows)
- Server-side guard in createCompanyFromOnboarding — returns
'org_number_exists' before the create RPC so we don't leave ghost
companies
- New /api/company/check-org-number endpoint for debounced client
checks
- Warning + disabled submit in Step2CompanyDetails
- Friendly error toasts in WelcomeOnboarding + BankIdCompanyPicker
- Mirror cleaned org_number onto companies.org_number on creation so
future duplicate checks and lookups are reliable
3. /onboarding ignored ?org_number= when the picker routed there as a
fallback. Now reads searchParams and pre-fills settings; also fixed
a latent bug where Step1's entity-type change wiped the pre-fill on
*first* selection (it should only reset on a genuine change).
Tests: duplicate-org guard (with formatted-input normalization),
check-org-number route (auth + 400 + exists true/false +
normalization).

* fix: address PR review feedback on duplicate-org guard
Greptile P1 findings + swedish-compliance feedback:
- findExistingCompanyByOrgNumber now throws on Supabase error instead
of silently returning null. Previously a DB outage or RLS
misconfiguration would bypass the entire duplicate guard and allow
duplicates through.
- createCompanyFromOnboarding catches the throw and returns a
user-facing error ("Kunde inte verifiera organisationsnummer"),
failing closed instead of open.
- companies.update({ org_number }) error is now checked and triggers a
rollback. Silent failure would leave the company without an
org_number, breaking all future duplicate checks for that entity.
- New normalizeOrgNumber helper validates 10- or 12-digit input,
strips the century prefix for 12-digit personnummer form, and
rejects anything else. Malformed input would have corrupted SIE4
(#ORGNR) and SRU (INFO.SRU) exports downstream.
- /select-company now uses loose `== null` for positionEnd — TIC has
been observed returning `undefined` for open-ended positions, which
strict `=== null` would silently filter out. Documented the two
downstream isCeased guards so future maintainers don't remove one
without the other.
- createCompanyFromTicRole refuses to provision when lookup.isCeased
(BFL 2 kap — bokföringsskyldighet ends at avregistrering).
BankIdCompanyPicker surfaces this client-side too.
- WelcomeOnboarding + BankIdCompanyPicker recognise new error codes:
org_number_invalid, company_ceased.
Tests: +4 cases covering malformed input rejection, fail-closed
behaviour on DB error, 12-digit personnummer normalization, and the
ceased-company refusal path. Full suite: 2306 passing.
Out of scope for this PR (follow-up):
- Partial unique index on companies(org_number) WHERE archived_at IS
NULL. Closes the race-condition window but needs a migration plus
any existing-duplicate cleanup — too risky for this hotfix.
- Rate limiting on /api/company/check-org-number. Endpoint is
auth-gated so not an immediate concern.

* fix: add Luhn validation and extract org-number normalization
Third round of PR review feedback (swedish-compliance):
- Add Luhn-10 check-digit validation to normalizeOrgNumber. Rejects
structurally invalid org_numbers (wrong check digit) at the boundary
instead of letting them propagate into SIE4 #ORGNR and SRU INFO.SRU,
where Skatteverket and receiving accounting systems would reject
them later anyway. Reuses the existing luhnValidate helper from
lib/bankgiro/luhn.ts (Bankgirot 10-modulen — same algorithm applies
to both Bolagsverket org numbers and Swedish personnummer).
- Extract normalizeOrgNumber into lib/company-lookup/normalize-org-number.ts
so the server action and /api/company/check-org-number use the same
rule. Previously the API route only stripped hyphens/spaces, so a
12-digit input would miss a stored 10-digit duplicate and mislead the
client debounce check ("not a duplicate" → submit → server rejects).
- /api/company/check-org-number now returns exists=false for
Luhn-invalid input rather than querying the DB. The submit-time
server action surfaces org_number_invalid, which is the right place
for the error.
Test coverage: dedicated normalize-org-number.test.ts (10 cases
covering both-lengths, Luhn, whitespace tolerance, garbage). Updated
existing tests to use Luhn-valid numbers (real Volvo 5560125790,
synthetic personnummer 8001011231). New failing-Luhn test in
actions.test.ts. New 12-digit-normalization and
luhn-invalid-returns-false tests in route.test.ts.
Full suite: 2315 passing.
Not fixed (out of scope for this hotfix):
- 10↔12 digit round-trip fragility for personnummer born 2000+. This
is a codebase-wide architectural choice (see lib/skatteverket/format.ts
which uses a two-digit-year heuristic to choose 19/20 at export).
Migrating to 12-digit storage is a separate refactor.
- Server-side re-fetch of TIC /lookup for isCeased. The trust boundary
here is user-to-their-own-onboarding, not adversarial; doubling TIC
API cost isn't proportionate.
