* feat(api): Phase 3 — transactions + reconciliation vertical

Closes out Phase 3 of the plan in one PR. After this, a 3rd-party agent
can fully manage a company's transaction ledger via the public API:
import bank data, walk the queue, categorize (manual / template /
counterparty / account-override), match payments to customer + supplier
invoices, reverse mistakes, and auto-reconcile the bank against the GL.

ENDPOINTS (12)

Reads:
  GET /transactions                          — cursor list, filters
  GET /transactions/{id}                     — detail
  GET /accounts                              — BAS chart, class filter
  GET /fiscal-periods                        — räkenskapsår list

Writes (single tx, idempotent + scoped):
  POST /transactions/{id}/categorize         — dry-run, CAS race guard
  POST /transactions/{id}/uncategorize       — dry-run, storno + reset
  POST /transactions/{id}/match-invoice      — storno conflicting JE,
                                                payment JE, link
  POST /transactions/{id}/match-supplier-invoice  — incl. FX diff handling

Writes (bulk, partial-success + all_or_nothing:true → 501):
  POST /transactions/ingest                  — up to 500 items
                                                (CSV + custom feeds)
  POST /transactions/batch-categorize        — up to 100 items

Reconciliation:
  POST /reconciliation/bank/run              — dry-run, applies matches
  GET  /reconciliation/bank/status           — health snapshot

All write surfaces mirror the dashboard's internal route compliance
behavior exactly — same engine functions, same Prong-B SI-match
suggestion intercept on categorize, same FX-diff handling on supplier-
invoice match, same optimistic-lock interlock on invoice status update.
No new bookkeeping primitives — every route delegates to the existing
`lib/bookkeeping/*` engine, `lib/transactions/ingest.ts`, and
`lib/reconciliation/bank-reconciliation.ts`.

SCOPES + ERRORS

Adds 12 entries to lib/auth/scopes.ts under transactions:read|write +
reports:read (accounts, fiscal-periods follow the same convention as
MCP tools). Adds 4 new error codes: TX_UNCATEGORIZE_NOT_BOOKED,
TX_UNCATEGORIZE_JE_NOT_POSTED, TX_INGEST_INSERT_FAILED,
TX_BATCH_CATEGORIZE_EMPTY.

TESTS

32 new integration cases across 5 suites:
  - transactions list / detail (4)
  - accounts + fiscal-periods (4)
  - categorize / uncategorize / match-invoice / match-supplier-invoice (9)
  - ingest + batch-categorize (7)
  - reconciliation run + status (5)
plus shared happy-path and edge cases (no-income, already-linked,
malformed body, scope rejection, dry-run shape).

Full suite green: 3270 passing (234 files). Build + lint clean.

* fix(api): address PR #464 review — Phase 3 hardening

Greptile P1 — cursor pagination broken in GET /transactions.
  encodeDefaultCursor was passed the YYYY-MM-DD `date` field, but
  decodeDefaultCursor's strict ISO 8601 timestamp regex rejected it,
  so every cursor decoded as null and the endpoint always returned the
  first page. Switched the cursor anchor to `created_at` (real ISO
  timestamp, total-orderable, unique within the company at the row
  insertion grain) and updated the sort to (created_at DESC, id ASC).
  The `date` column remains in every row + filterable via ?date_from /
  ?date_to. Updated the registry description to reflect the change.

Greptile P1 — JE soft-fall in match-invoice + match-supplier-invoice.
  When the payment journal entry creation threw (any non-
  AccountsNotInChartError), the catch block recorded the error string
  but execution CONTINUED, marking the invoice paid + inserting a
  payment row + linking the transaction with no GL entry. The dashboard
  internal route soft-fails here intentionally and surfaces a banner so
  the user can re-book; for the v1 surface a partial state is strictly
  worse than a clean failure to retry. Both routes now return:
    - INVOICE_PAID_BOOK_FAILED (match-invoice)
    - MATCH_SI_RECORD_PAYMENT_FAILED (match-supplier-invoice)
  before any state mutation. Removed `journal_entry_error` from both
  response schemas — strict mode means it can never be set on a 200.

Greptile P1 — `overdue` supplier invoices fail the optimistic lock.
  The early status guard accepted `overdue` as matchable, but the
  downstream `.in('status', ['registered', 'approved', 'partially_paid'])`
  excluded it, returning MATCH_SI_NOT_OPEN for a legitimately payable
  invoice. Added `overdue` to the optimistic-lock list.

Greptile P1 + Swedish-compliance — CAS-race orphan cancellation.
  Direct `.update({ status: 'cancelled' })` on the orphaned JE was
  silently blocked by enforce_journal_entry_immutability (the engine
  writes JEs as posted) and the `voucher_gap_explanations` row claimed
  the entry was cancelled when it wasn't. BFL 5 kap 5 § requires
  corrections via a reversing entry. Both /transactions/{id}/categorize
  and /transactions/batch-categorize now call `reverseEntry()` on the
  orphan; the storno pair keeps the verifikationsnummer series unbroken
  so the gap-explanation insert is no longer needed.

Greptile P2 + Swedish-compliance — hardcoded category on match-invoice.
  The dashboard internal route writes `category: 'income_services'` for
  every matched invoice payment, overwriting any prior categorization
  with a wrong BAS classification for goods sales / rental income.
  Fixed by preserving the existing transaction.category if set, only
  defaulting to `income_services` when the row had never been
  categorized before.

Compliance Swarm V2.4 — reconciliation date range guard.
  Added a 366-day cap on date_from / date_to via Zod refine. Longer
  reconciliations should be paged.

Greptile P2 — dry-run dedup limitation.
  Added a pitfall note documenting that the ingest dry-run only checks
  external_id-based dedup; content-based dedup (date+amount against
  already-booked rows) only runs in the live pipeline.

Swedish-compliance — BFL chapter typo on fiscal-periods registry.
  "BFL 6 kap" → "BFL 5 kap 2 §" (the löpande bokföring deadline).

Deferred (with rationale documented):
  - OWASP V8.2.1 cross-tenant via path: false positive — wrapper sets
    ctx.companyId from the URL after membership check (recurring across
    swarm runs).
  - OWASP V4.5 select('*') on transactions/invoices: same as Phase 2 —
    those rows feed engine functions that need the full shape.
  - OWASP V2.3 multi-write atomicity (match endpoints): would need a
    Postgres RPC; separate refactor.
  - Swedish-compliance kontantmetoden partial-payment status: same
    semantics as the dashboard internal route; engine-level decision
    out of v1's scope.
  - Greptile P3 `reversible: false` on uncategorize: technically
    correct (the storno itself isn't reversible via this verb).

Tests + build green: 3270 passing, lint clean.

* fix(import): distinguish network errors in the SIE upload step

Adds a dedicated 'network' errorType so the SIE import wizard surfaces
"Uppladdningen misslyckades" with a connectivity-focused remediation
instead of the generic 'parse' fallback (which suggested checking the
SIE file format — wrong direction when the issue is actually offline /
flaky upload).

* fix(api): address PR #464 swedish-compliance re-run findings

The Swedish-compliance bot edited its existing comment in place after
the prior fix push (so created_at filtering missed the re-run). The
re-run flagged 6 new substantive findings against the post-fix code.

Fix 1 — Orphan storno failure leaves an unresolved immutability gap
  (categorize + batch-categorize).
  When reverseEntry() on the CAS-race orphan fails, the orphan stays
  posted and untraceable. BFL 5 kap 5 § requires every correction be
  traceable. Both paths now insert a voucher_gap_explanations row in
  the catch branch flagging "automatisk storno misslyckades — manuell
  reconciliation krävs", so the orphan is logged at the audit-trail
  level rather than only in app logs.

Fix 2 — Period-lock pre-check (categorize + batch-categorize).
  enforce_period_lock and enforce_company_lock_date triggers block JE
  inserts on locked/closed periods, but Supabase surfaces those as a
  generic 500. Added a new lib/api/v1/check-period-lock.ts helper that
  performs the same check the trigger would (company-wide lock date,
  is_closed, locked_at), and both routes now return a structured
  PERIOD_LOCKED response (existing error code, 400) with reason +
  fiscal_period_id details before the engine call. Note: this is an
  ergonomics check (TOCTOU window between check and insert) — the
  trigger remains authoritative.

Fix 3 — Ingest dry-run now performs content-based dedup too.
  The earlier doc-only note was a compliance miss: an integrator
  relying on dry-run to confirm uniqueness could ingest duplicate
  affärshändelser, violating BFL 5 kap. The dry-run now runs BOTH
  external_id dedup AND content-based (date+amount-against-booked)
  dedup over the request's date range — same query the live pipeline
  uses. Pitfall doc updated accordingly.

Fix 4 — fiscal-periods response now carries duration_days +
  exceeds_18_months computed fields.
  An automated client (year-end wizard, audit tool) can spot a
  non-compliant period sequence (BFL 3 kap, 18-month cap) without
  re-implementing date arithmetic. 549-day cap (18 calendar months)
  is used to keep the comparison deterministic across leap years.
  First-year exceptions still require human judgment; the boolean is
  a flag, not a verdict.

Deferred (with rationale documented in commit, not retried):
  - uncategorize storno memo: reverseEntry() doesn't accept a reason
    parameter today and the JE-level back-reference exists already
    via reversed_by_id / reverses_id. Engine signature change is
    out of v1's scope.
  - VAT integrity check on partial payment in match-invoice: the
    behavior is fully delegated to createInvoicePaymentJournalEntry.
    The bot itself recommends auditing against the engine; that is
    an engine-layer concern and the dashboard internal route uses
    the same path.
  - 366-day reconciliation window (advisory): no statutory basis;
    operational guard.
  - match-supplier-invoice FX path against ML 8 kap 21–23 §
    (advisory): engine-layer concern.

Tests + build green: 3270 passing, lint clean. Touched-suite tests
(transactions, fiscal-periods, accounts, reconciliation) re-run; the
fiscal-periods test asserts the new derived fields.

* fix(api): PR #464 round-3 review fixes (re-run after period-lock + dedup)

Both compliance bots edited their existing comments in place after the
prior fix push. New findings against the post-fix code:

Fix — VAT account suppression too broad on account_override.
  categorize/route.ts dropped vat_lines for ANY class-2 override, but
  BAS class 2 includes the 26xx VAT clearing accounts themselves. Result:
  a user override TO a VAT account silently lost the auto-VAT line.
  Tightened to `account_class === 2 && !account_override.startsWith('26')`.
  The override-to-2440-leverantörsskulder case is unchanged (correctly
  drops auto-VAT); the override-to-2611-utgående-moms case now keeps the
  VAT line.

Fix — fiscal-periods 18-month cap uses calendar arithmetic.
  EIGHTEEN_MONTHS_DAYS = 549 was a generous approximation (18 calendar
  months span 540–549 days). Replaced with proper month-anchor math:
  start_date + 18 months computed via setUTCMonth-style year/month
  rollover, then `period_end > anchor` is the violation. Manual day-
  arithmetic on the year part avoids JS's clamp-overflow on Aug-31-style
  start dates. duration_days helper preserved for the response field.

Fix — match-invoice no longer hardcodes 'income_services'.
  When the transaction has no prior category, the route now leaves the
  field UNTOUCHED in the UPDATE (existing default 'uncategorized' or
  whatever was there persists). The response surfaces null for the
  uncategorized case so a caller can detect "needs human classification"
  without inspecting the DB. The auto-default to income_services was
  flowing into BAS 3001/3041/3530 selection mismatches and INK2R/SRU
  mis-reporting for goods/rental flows. Existing-category transactions
  still propagate their value.

Doc — accounts.ts BAS 5/6 description tightened.
  Was "5=other costs, 6=other costs" — both true but flatten distinct
  subgroups. Now spells out 5xxx (rents/supplies/services) and 6xxx
  (marketing/professional/IT) under övriga externa kostnader, with a
  pointer to the canonical BAS chart.

Deferred (with rationale documented):
  - voucher_gap_explanations in SIE export coverage: verification ask;
    SIE export audit is a separate task, not this PR's scope.
  - Dry-run dedup parity with full live pipeline: my dedup matches the
    live pipeline's primary checks (external_id + content date+amount
    against booked rows). Achieving exact parity would need refactoring
    lib/transactions/ingest.ts to expose a shared dedup helper.
  - FX sign convention in match-supplier-invoice: identical to the
    dashboard internal route; if the engine sign convention is wrong
    both surfaces are wrong. Engine-layer audit, not v1 surface.
  - OWASP V8.2.1 cross-tenant via path: recurring false positive — the
    wrapper sets ctx.companyId from the URL only AFTER company_members
    membership check.
  - V2.3 multi-write atomicity in match endpoints: would need a Postgres
    RPC; separate refactor.
  - check-period-lock TOCTOU on no_fiscal_period (advisory note): the
    engine's ensureFiscalPeriod helper creates an open period; if the
    transaction date sits in a historical gap, the engine creates the
    period unlocked. The trigger remains the authoritative gate.

Tests + build green: 3270 passing, lint clean.

* fix(api): PR #464 round-4 review fixes (compliance bot re-run)

The compliance swarm went from 20 → 10 findings after round-3, but the
swedish-compliance bot caught 5 issues my fixes introduced or didn't
fully cover.

Fix — VAT account suppression narrowed to BAS 2610–2649.
  My round-3 fix exempted any account starting with '26' from VAT-line
  suppression, but BAS 26xx includes 2650 (momsredovisningskonto) and
  2690 (diverse), neither of which is a moms-line account. Auto-VAT
  posted against 2650 would double-post on the moms reconciliation
  account. Tightened the exception to the 2610–2649 range (utgående
  + ingående moms accounts only).

Fix — exceedsEighteenMonths month-end overflow.
  My round-3 manual month math still passed `startD` raw to Date.UTC,
  which clamps Aug 31 + 18 months to Mar 3, making the cap LATER than
  the BFL 3 kap 1 § ceiling (false negative). Now clamps `startD` to
  the last valid day of the target month using `Date.UTC(year, m+1, 0)`.

Fix — ingest dry-run dedup float-key normalization.
  Built the content-dedup set from `${tx.date}|${tx.amount}` where
  amount is a JS number stringified directly — `-349.5` from JSON vs
  `-349.50` from a Postgres numeric round-trip miss-match. Normalized
  both sides to .toFixed(2). SIE imports commonly carry trailing-zero
  precision, so this would have caused the dry-run to under-report
  duplicates (a BFL 5 kap löpande-bokföring concern: an integrator
  trusting the dry-run could double-book affärshändelser).

Fix — CAS-race voucher_series fallback no longer files under 'A'.
  Both categorize and batch-categorize used `voucher_series || 'A'`
  for the voucher_gap_explanations row. If the orphan JE had no series,
  the gap would be indexed under series 'A' and missed by any series-
  specific audit query (BFL 5 kap 6 §). Now skips the gap row entirely
  when no series is set — the error log already captures the orphan
  for human reconciliation; filing under the wrong key is strictly
  worse than not filing.

Fix — match-invoice rejects kontantmetoden partial payments.
  Under kontantmetoden, utgående moms must be reported per actual
  receipt (ML 13 kap 8 §). The cash-method-partial branch was falling
  through to createInvoicePaymentJournalEntry (the accrual 1510/1930
  clearing path), which doesn't model the per-installment moms event.
  Rather than silently over-report moms, refuse with a VALIDATION_ERROR
  pointing the caller to either wait for the full payment or switch to
  faktureringsmetoden. Full cash-method payments still flow through
  createInvoiceCashEntry (the correct kontantmetod path).

Deferred (with rationale):
  - `uncategorize` resets journal_entry_id to null: dashboard parity;
    the JE-side back-reference (reversed_by_id / reverses_id) preserves
    the audit pair. Adding a separate reversal_journal_entry_id column
    on transactions is a schema change out of v1 scope.
  - OWASP V8.2.1 cross-tenant: recurring false positive.
  - OWASP V2.2 inline Zod filter schemas: structural consistency
    decision — kept in-route to match other v1 endpoints; a future
    refactor can centralize when it justifies the cost.
  - OWASP V16 add userId/companyId to storno-failure log: txLog
    already carries both via ctx.log.child; not changing call-site
    syntax for compliance theatre.
  - Engine-layer FX sign convention in match-supplier-invoice
    (advisory): identical to dashboard internal route.

Tests + build green: 3270 passing.

* fix(api): match-supplier-invoice storno conflicting JE before booking

The match-invoice route stornoes any conflicting auto-categorization JE
before posting the payment entry; match-supplier-invoice was missing
the symmetric guard. If a transaction was previously auto-categorized
(e.g. expense_office with a 5460/1930 entry), matching it to a supplier
invoice would post a second 2440/1930 entry while leaving the original
posted — two verifikationer for one affärshändelse, a BFL 5 kap 6 §
integrity violation. Storno-before-match now applies in both routes,
with the same fail-closed semantics (storno failure aborts before any
state change).

Jakob WennbergandClaude Opus 4.7 01e99d3220 feat(api): v1 invoice PDF + customer bulk-create (Phase 2 PR-B-3) (#460)
Closes out the Phase 2 invoices+customers vertical. After this PR, every
write/read the dashboard does on these two resources is reachable via the
public API.

GET /api/v1/companies/{companyId}/invoices/{id}/pdf
  Read-only application/pdf endpoint. Mirrors the dashboard's internal
  /api/invoices/[id]/pdf so a downloaded PDF is byte-equivalent across
  surfaces. Drafts render with the "faktura-utkast-<id-slice>.pdf"
  filename (preview before send is a legitimate workflow); sent invoices
  use "faktura-<number>.pdf"; credit notes use "kreditfaktura-<number>.pdf"
  and embed the original invoice's löpnummer per ML 17 kap 22–23§
  back-reference; proforma + delivery notes get their own prefixes.

  Error codes: INVOICE_PDF_RENDER_FAILED (500, new),
  INVOICE_SEND_COMPANY_SETTINGS_MISSING (404, reused — same condition,
  same remediation).

POST /api/v1/companies/{companyId}/customers/bulk-create
  Mirrors /invoices/bulk-create exactly: same `{ results, summary }`
  shape, same all_or_nothing: true → 501 NOT_IMPLEMENTED contract, same
  50-item cap, same sequential processing. Per-item rollback isn't
  needed (customer insert is a single row), but per-item 23505 →
  CUSTOMER_DUPLICATE_ORG_NUMBER failure surfaces in the results array
  without echoing org_number (GDPR Art.5(1)(c): for sole traders
  org_number IS the personnummer). VIES validation runs per item,
  best-effort — a timeout leaves vat_number_validated=false but does
  NOT fail the item.

Registry: extended EndpointDefinition.response with an optional
  `contentType` field so the OpenAPI generator can emit
  `format: binary` schemas for non-JSON responses. The PDF endpoint is
  the first consumer; future binary endpoints (SIE export, ICS feeds)
  use the same hook.

Scope catalogue: added GET .../pdf → invoices:read,
  POST .../customers/bulk-create → customers:write.

Tests: 14 new integration cases (7 for PDF: sent / draft / credit-note
filename, 404, render-error 500, non-UUID 400, scope rejection; 7 for
customer bulk-create: happy path, dup-org error masking, max-50 cap,
all_or_nothing 501, dry-run preview, empty array, scope rejection).
Suite green: 3232 passing. Build + lint clean.

* feat(api): v1 invoice :send + bulk-create action verbs (Phase 2 PR-B-2b-3 + PR-B-2c)

Combined chunk: ship the full :send pipeline and partial-success bulk
creation in one PR, plus include the dangling /reset-password middleware
fix that completes PR-455's password-recovery flow.

POST /api/v1/companies/:companyId/invoices/:id/send
  Full send pipeline mirroring the internal route, hardened for the public
  API surface: email-configured check, draft-only guard, cancelled /
  delivery-note / credit-note / missing-moms_ruta rejections, customer
  email check, company-settings fetch, F-series invoice-number allocation
  (atomic at :send per ML 17 kap 24§ p.2, not at draft create), preflight
  PDF render before number consumption, final PDF render, email send,
  point-of-no-return status flip, BFL 5 kap journal entry, document
  archival, invoice.sent event emit. Post-send failures (journal entry,
  archive) surface via a `warnings` array rather than failing the response
  — the invoice IS sent at that point. Dry-run validates the pipeline +
  preflight PDF without allocating a number or hitting the provider.
  Error codes: INVOICE_SEND_EMAIL_NOT_CONFIGURED (503),
  INVOICE_SEND_NO_CUSTOMER_EMAIL / _CANCELLED /
  _COMPANY_SETTINGS_MISSING (400), INVOICE_UPDATE_NOT_DRAFT (409),
  INVOICE_SEND_PDF_RENDER_FAILED / _NUMBER_ASSIGN_FAILED (500),
  INVOICE_SEND_PROVIDER_FAILED (502).

POST /api/v1/companies/:companyId/invoices/bulk-create
  Batch create up to 50 invoices in a single call, sequential processing,
  partial success: `{ results: [{ ok, request_index, data?, error? }],
  summary: { total, succeeded, failed } }`. Per-item rollback on items
  insert failure (delete the parent invoice row). Emits invoice.created
  per success. Dry-run wraps results in a preview without inserting.
  `all_or_nothing` is accepted but reserved for a future PR.

lib/supabase/middleware.ts
  Add /reset-password bypass before the authenticated-user redirect so
  password-recovery sessions don't bounce to '/'. This should have landed
  in PR-455 — the `git add 'app/(auth)'` filter missed the middleware
  file at lib/. Without this the recovery email link silently fails for
  the recipient.

Tests: 14 new integration tests across both routes (happy path,
provider failure, scope rejection, draft-only guard, dry-run shape,
bulk partial-success, max-50 enforcement, validation error). Full suite
green (3207 passing, 1 unrelated pre-existing pg-real failure).

* fix(api): address PR #458 review — :send + bulk-create hardening

Greptile P1: silent zero-row update after email delivery.
  PostgREST returns { error: null } on 0-row UPDATEs. The post-email
  status flip used `.eq('status', 'draft')` as an optimistic lock but
  never inspected the row count, so a concurrent state change (race,
  double-send from another session) would leave the DB row in 'draft'
  while the response claimed 'sent' and the email was already gone.
  Fix: `.select('id')` after the update and check `flipRows.length`;
  on 0-row miss, push STATUS_UPDATE_FAILED warning AND change the
  response status to 'draft' so the caller can reconcile.

Greptile P1: re-read error swallowed; invoice_number could vanish
  from the response.
  After ensureInvoiceNumber, the re-read query destructured only `data`,
  silently dropping `error`. A transient connection failure would leave
  `numbered` null and `finalInvoiceNumber` undefined; JSON serialization
  would then omit the field, violating the documented response schema.
  Fix: capture `reReadErr`, log a warning, fall back to typed.invoice_number
  (which was just written by the RPC and is authoritative in-memory).
  Apply the same fallback at the top-level `ok()` call.

Greptile P2 + Compliance Swarm V2.3 + Swedish-compliance kreditfaktura:
  reject credit notes from :send.
  The :credit endpoint creates credit notes atomically in 'sent' state
  with their own number — there is no v1 path that produces a draft
  credit note, so reaching :send with credited_invoice_id set is misuse
  or manual DB editing. Allowing it would assign an F-series number to
  a kreditfaktura (ML 17 kap 22–23§ require a distinct kreditfaktura
  series and a back-reference that this route would not enforce). Fix:
  reject with VALIDATION_ERROR pointing at /credit. Removes a stretch
  of dead code (originalInvoiceNumber lookup, kreditfaktura filename
  branch) that can never execute now.

Greptile P2: all_or_nothing: true silently treated as false.
  A caller asking for atomic semantics must not get partial-success
  behaviour with no runtime signal. Fix: reject with new
  NOT_IMPLEMENTED error (501) plus a details.field pointer. Schema
  still accepts the flag for forward compatibility once a DB-side RPC
  ships. New error code added to lib/errors/structured-errors.ts.

Tests: 3 new integration cases (credit-note rejection, status-flip
no-op warning, all_or_nothing 501). Suite green: 3218 passing.
Build clean, lint clean.

* fix(api): PR #458 follow-up — defense-in-depth + comment precision

OWASP V8.2.1 (bulk-create): use DB-returned customer.id at insert time
  instead of input.customer_id. The .eq() pair already enforces company
  scoping at fetch, but echoing the trusted value from the query makes
  the guarantee explicit at the call site and immune to refactoring
  drift. Same change in the dry-run preview shape.

Swedish-compliance wording: the credit-note rejection comment now
  spells out BOTH ML 17 kap 22–23§ requirements — distinct kreditfaktura
  series AND explicit back-reference to the original invoice's
  löpnummer — so any future v1 path that does support credit-note send
  starts from a complete spec.

Company-settings select: kept select('*') with an explanatory comment
  rather than enumerating columns. The InvoicePDF template consumes the
  full CompanySettings shape; a partial allow-list risks silently breaking
  rendering, and the table has no sensitive columns today (API tokens,
  billing data live in scoped tables). Documents the trade-off so the
  next reviewer doesn't re-litigate.

Deliberately not changed:
  - Math.round → Math.trunc on VAT öre: CLAUDE.md mandates Math.round
    project-wide; unilateral deviation here would diverge from the
    bookkeeping engine and POST /invoices.
  - 207 Multi-Status on partial post-email failures: gnubok's convention
    is warnings[] in the 200 envelope; a per-route status divergence
    would break the response contract clients rely on.
  - Wrapper membership double-check (OWASP V8.2.1 send route): the
    withApiV1 wrapper sets ctx.companyId from the URL after the
    membership check — recurring false positive in this swarm.

Tests + build + lint clean. 17/17 in the touched suites.

Jakob WennbergandClaude Opus 4.7 cd96e5ec26 feat(api): v1 invoice :mark-paid + :credit action verbs (Phase 2 PR-B-2b combined) (#455)
* feat(api): v1 invoice :mark-paid + :credit action verbs (Phase 2 PR-B-2b combined)

Bigger PR per the user's request. Lands the remaining two journal-entry-
centric action verbs together — they share the same lifecycle pattern
established in :mark-sent (idempotent, dry-runnable, scope-gated,
warnings on partial-state failures).

POST /api/v1/companies/:companyId/invoices/:id/mark-paid
- Books a payment against a sent / overdue invoice. Updates status to
  paid (or partially_paid when remaining_amount > 0). Three booking paths:
  - Faktureringsmetoden (accrual default): Debit 1930 / Credit 1510 via
    createInvoicePaymentJournalEntry — settles AR.
  - Kontantmetoden (cash): Debit 1930 / Credit revenue + Credit VAT via
    createInvoiceCashEntry — revenue recognition happens HERE under cash.
  - Custom lines (partial payment): caller-supplied balanced journal lines
    via createJournalEntry directly. Validated for balance (sum debits ==
    sum credits, both > 0) → 400 INVOICE_PAID_LINES_UNBALANCED otherwise.
- Optional body: { payment_date?, exchange_rate_difference?, lines? }
- Race-condition guard: status update matches .in(['sent','overdue',
  'partially_paid']) so a concurrent payment returns 409 INVOICE_PAID_RACE.
- Emits invoice.paid (new event type, added to lib/events/types.ts with
  paymentAmount + paymentDate in the payload).

POST /api/v1/companies/:companyId/invoices/:id/credit
- Issues a kreditfaktura against a sent / paid / overdue invoice
  (ML 17 kap 22–23§). Creates a NEW invoice row with:
  - invoice_number = "KR-<original>"
  - credited_invoice_id = original id
  - status = 'sent'
  - All amounts negated (subtotal, vat_amount, total, items quantities/totals)
- Items mirror the original with negated values; inserted in a separate
  step with company-scoped rollback DELETE on failure.
- Flips original invoice to status='credited'. Warns ORIGINAL_NOT_FLIPPED
  if the flip fails (the credit note still exists; operator reconciles).
- Posts reverse journal entry via createCreditNoteJournalEntry (accrual
  only; cash basis defers to refund time).
- Emits credit_note.created (existing event in the bus).

Both endpoints:
- Use the established wrapper + Idempotency-Key + dry-run + warnings
  pattern from :mark-sent.
- Validate document_type (no delivery_notes), credited_invoice_id (no
  recursive credits), and status before any mutation.
- Use explicit column projections (no SELECT *).
- Sanitize pg_message from client responses (kept in logs).
- Emit error-level logs on partial-state failures + surface warnings to
  the caller via meta.warnings.

Event types union (lib/events/types.ts) gains invoice.paid; credit
uses the existing credit_note.created event.

URL convention: plain /verb subpaths (e.g. /invoices/:id/mark-paid),
consistent with :mark-sent. Stripe/QuickBooks pattern, not the
AIP-style :verb that Next.js routing fights.

17 new tests covering happy paths (accrual + cash for mark-paid),
custom-lines balance validation, dry-run preview, document-shape
guards, scope, idempotency, race conditions, and credit-of-credit /
delivery-note rejection.

3194/3194 vitest pass; build clean; lint clean on v1 paths.

* fix(api): address PR #455 review + include password-recovery fixes

PR #455 review fixes:

- Greptile P1 (CLAUDE.md architecture rule): API routes that emit events
  via eventBus must call ensureInitialized() at module level to wire
  extension event handlers. Neither :mark-paid (invoice.paid) nor :credit
  (credit_note.created) had it — nor did the already-merged :mark-sent,
  POST /invoices, POST /customers, etc. Fixed once at the wrapper layer:
  ensureInitialized() now runs at module import of lib/api/v1/with-api-v1.ts,
  so EVERY v1 route gets the init at import time. Single source of truth
  prevents future routes from forgetting (idempotent guard makes the
  repeated call safe). Cleaner than per-route copy of the call.

- Swarm PI1.3 (low): 0.005 epsilon in mark-paid was undocumented. Added
  a comment explaining: after rounding to 2 decimals, newRemaining is in
  steps of 0.01; values ≤ half-an-öre only arise from float artefacts.

Pushing back (recurring triage, consistent with prior PRs):
- V8.2.1 + CC6.3 × 4 "ctx.companyId vs params.companyId mismatch" —
  impossible by construction. The wrapper sets ctx.companyId FROM the URL
  params after the membership check. They are guaranteed equal.
- V2.3 + A.8.15 + A.8.28 atomicity / floating-point / partial-failure
  alerts — same architectural / cross-surface deferred work as prior PRs;
  matches internal /api/invoices pattern precisely.
- V4.5 account_number allowlist — engine validates it.
- V2.4 idempotency TOCTOU — wrapper handles via DB unique constraint.
- Art.5(1)(f) PII in logs, A.8.11 dry-run preview scope, A.8.15 partial-
  failure naming, test scope coverage — all recurring triage.

Password-recovery flow fixes (included per request — pre-existing
working-tree changes the user authored):

- app/(auth)/auth/callback/route.ts: when the callback exchanges a
  recovery token (type='recovery' or next='/reset-password'), redirect
  directly to /reset-password instead of running onboarding/MFA/
  dashboard checks. Previously users clicking the password-reset email
  got bounced through onboarding.
- lib/supabase/middleware.ts: /reset-password no longer bounces
  authenticated users to / (the recovery flow lands here with a fresh
  session by design — the user is *supposed* to call updateUser({
  password }) on this page).
- app/(auth)/login/page.tsx: shows an error banner when ?error=auth_error
  is set (expired/used recovery link), with a button to request a new
  one. Wrapped the page in <Suspense> because useSearchParams() now
  forces dynamic rendering (Next.js 16 static-prerender bail-out
  otherwise).
- app/(auth)/auth/callback/__tests__/route.test.ts: new test file
  covering the recovery callback path.

3197/3197 vitest pass (3194 prior + 3 from the new auth-callback tests).
Build clean.

* fix(api): mark-paid uses remaining_amount as default payment, not total

Real correctness fix from Swedish-compliance review on PR #455. When no
customLines is supplied, mark-paid previously defaulted paymentAmount to
typed.total. Combined with the race-condition guard that allows the
status UPDATE to flip a partially_paid invoice to paid, this could
over-credit AR in a race scenario:

1. Invoice in 'sent' status, total=12500, remaining=12500.
2. Concurrent partial payment lands first → status='partially_paid',
   remaining=7500.
3. The full-payment request's pre-flight saw 'sent' and passed; its
   UPDATE matches partially_paid (race guard allows it). With the old
   logic the journal entry was for total=12500 against an AR balance
   of only 7500 — a 5000 over-credit.

Using remaining_amount as the default eliminates this. Same end state
in the common case (no prior partial); correct booking in the race.

3197/3197 vitest pass.

Jakob WennbergandClaude Opus 4.7 e4186523f9 feat(api): v1 invoice :mark-sent action verb (Phase 2 PR-B-2b-1) (#454)
* feat(api): v1 invoice :mark-sent action verb (Phase 2 PR-B-2b-1)

First invoice action verb. Transitions a DRAFT invoice to 'sent' status —
intended for invoices delivered outside gnubok (Peppol, postal, custom
SMTP). The full :send pipeline (PDF + email) builds on top of this in
PR-B-2b-3.

URL convention: plain /verb subpath (e.g. /invoices/:id/mark-sent), not
the AIP-style :verb suffix the plan originally proposed. Next.js routes
don't support `:` in folder names, and the Stripe/QuickBooks idiom is
plain subpaths anyway. The agent-facing docs can still describe the
action however we want.

What happens on commit:
1. F-series invoice_number allocated atomically via the
   generate_invoice_number RPC (per the PR-B-2a design — drafts have
   invoice_number=null until this transition, preserving the unbroken
   löpnummer series required by ML 17 kap 24§ p.2).
2. Status flips draft → sent.
3. For accrual + real invoices, posts the invoice journal entry via
   createInvoiceJournalEntry (Debit AR 1510 / Credit revenue 3xxx /
   Credit output VAT 26xx). Cash basis skips this; booking happens at
   payment time.
4. Writes journal_entry_id back onto the invoice row.
5. Emits invoice.sent.

Race-condition guard: the status update matches .eq('status', 'draft'),
so a concurrent transition between pre-flight and update returns 409
INVOICE_UPDATE_NOT_DRAFT.

Dry-run: returns a preview of the post-send invoice state including a
would_create_journal_entry flag and the resolved accounting_method.
invoice_number can't be predicted exactly (atomic sequence allocation)
so the preview shows a marker rather than a fake number.

PDF archival is deliberately NOT in this PR. The internal route does
it, but PDF rendering + document upload is a meaningful surface area
that belongs with :send (PR-B-2b-3) where email + PDF land together.

Test infrastructure: the makeFlexibleSupabase mock now supports
per-table result QUEUES (array form returns results in order across
multiple calls; single value returns same result every time). Required
to mock the pre-flight read (status=draft) and post-update read
(status=sent) on the same `invoices` table inside one request.

9 new tests covering happy path, idempotency, scope, draft-only guard,
delivery-note rejection, 404, UUID validation, dry-run preview shape,
and cash-method skip. 3174/3174 vitest pass; build clean.

* fix(api): address PR #454 review (Greptile + swarm + Swedish compliance)

Real bugs / contract violations:

- Greptile P1 (guard order): the delivery_note guard ran AFTER the
  status check, so a sent delivery note returned 409 instead of the
  documented 400. Reordered: document-shape guards (delivery_note +
  credit_note + missing moms_ruta) now run before the status check.
- Greptile P1 (journal_entry_id write-back): Supabase returns
  { data, error } and never rejects on DB errors, so a write-back
  failure produced no log and left the invoice with a real journal
  entry but no pointer. Now destructured + escalated to error log AND
  surfaced as a warning in the response.
- Swedish: credit notes (credited_invoice_id !== null) were not
  rejected — they would have been posted via createInvoiceJournalEntry
  with the wrong sign (Debit AR / Credit revenue instead of the
  inverse). Now explicitly rejected; credit-note path goes through
  POST /:id/credit (PR-B-2b-4).
- Swedish: moms_ruta now validated in the pre-flight. A null value
  would silently default to 25% domestic in the journal-entry
  generator — wrong for reverse-charge / EU-service / zero-rated
  invoices. Real ML 17 kap 24§ concern.

Partial-state visibility (Swedish + Swarm V2.3 + A.8.15 + PI1.3):

The response now carries an optional `warnings: [{ code, message }]`
field when the status flip succeeded but a follow-up step failed
(journal entry creation, event emission, or journal_entry_id write-
back). Three warning codes:
  - JOURNAL_ENTRY_NOT_POSTED — verifikation missing; BFL 5 kap
    reconciliation required
  - JOURNAL_ENTRY_ID_WRITEBACK_FAILED — entry exists but invoice row
    has no pointer
  - EVENT_EMIT_FAILED — webhook subscribers may miss this transition
All three escalate to error-level logs. The architectural fix
(transactional Postgres RPC that bundles allocation + status flip
+ journal entry) is tracked as cross-surface compliance work; the
warnings field is the agent-facing signal until that lands.

The F-series race window (number allocated before status flip; a
concurrent transition can leave a consumed-but-orphaned number, ML
17 kap 24§ p.2 gap) is now explicitly documented in the route
docstring rather than hidden in implementation. Same residual issue
exists in the internal route; fix needs the transactional RPC.

Pushing back (consistent with prior triage):
- V8.2.1 explicit ownership check (wrapper handles — false positive)
- Cross-tenant IDOR test (duplicates wrapper test coverage)
- Pseudonymise IDs in logs (operational value > theoretical risk)
- Structured audit event sink (current ctx.log.info IS structured)
- Test fixture A.8.33 (NODE_ENV guard in place; Acme AB is canonical
  synthetic placeholder)
- Projection column narrowing (fields ARE used in the flow)
- company_settings hard-fail on miss (accrual default is normal)

3 new tests covering credit-note rejection, missing moms_ruta, and
the journal-entry-failed warnings path. Plus the delivery-note test
now asserts the guard ordering works for sent delivery notes too.
3177/3177 vitest pass; build clean.

Jakob WennbergandClaude Opus 4.7 d29b87fb80 feat(api): v1 customer writes (Phase 2 PR-B-1) (#452)
* feat(api): v1 customer writes (Phase 2 PR-B-1)

First slice of Phase 2 PR-B from the agent-native v1 plan. Customer writes
are the simplest write surface — no journal entries, no PDF, no email —
which makes them the right place to validate the dry-run + idempotency
pipeline before applying it to invoice flows in PR-B-2.

New endpoints:
- POST   /api/v1/companies/:companyId/customers       (idempotent, dry-runnable)
- PATCH  /api/v1/companies/:companyId/customers/:id   (idempotent, dry-runnable)
- DELETE /api/v1/companies/:companyId/customers/:id   (soft-delete via
        archived_at; idempotent re-archiving; dry-runnable; 204)

All three require customers:write scope (added to V1_ENDPOINT_SCOPES). All
three require Idempotency-Key (mandatory — wrapper option
requireIdempotencyKey: true). All three accept ?dry_run=true or
X-Dry-Run: true and return a 200 OK preview with X-Dry-Run header set.

New shared infrastructure:
- lib/api/v1/dry-run.ts — dryRunPreview() (validation-only, no staging) and
  dryRunStaged() (financial writes; populated in later phases). Defines the
  preview response shape that POST/PATCH/DELETE share. Future financial
  writes (invoices, journal entries) will reuse the staged variant.

Pre-existing PR-A bugs fixed:
- CustomerType enum in customers/route.ts had wrong values ('business',
  'eu_individual', 'non_eu'). Canonical enum is ['individual',
  'swedish_business', 'eu_business', 'non_eu_business']. Fixed.
- INDIVIDUAL_TYPES masking referenced non-existent 'eu_individual'.
  Only 'individual' refers to a natural person (Swedish sole trader where
  org_number = personnummer).

Wrapper bug fix:
- The idempotency body-hashing flow was consuming the original request's
  body before passing it to the handler. In Node's vitest environment the
  cloned request's body became empty, so the handler's request.json()
  returned {}. Fix: read body from a clone for hashing, leave the
  original intact for the handler.

VIES re-validation on PATCH preserves existing best-effort behaviour.
Customer.created event emission on POST so future webhook delivery
(Phase 2 PR-C) can subscribe.

23 new tests covering happy path, dry-run preview, idempotency-key
enforcement, scope checks, UUID validation, duplicate-org conflict,
soft-delete semantics. 3150/3150 vitest pass; build clean; lint clean
on v1 paths.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(api): address PR #452 review (Greptile + swarm + Swedish compliance)

Real bugs (all reviewers agreed):
- POST registerEndpoint example used the old customer_type 'business'
  enum value that this PR was already fixing. Now uses 'swedish_business'
  consistently between code, schema, and docs.
- DELETE docstring claimed "Refuses to delete if open invoices remain"
  but the handler unconditionally archived. Swedish compliance flagged
  this as a real ML 17 kap 24§ concern (archived customer + open
  invoice can block kreditfaktura issuance). Added the pre-flight check:
  DELETE now returns 409 CUSTOMER_HAS_INVOICES with the open count when
  any open invoice (sent / partially_paid / overdue) references the
  customer. Docstring updated to match.
- PATCH advertised archived_at: null for un-archive but did not actually
  apply it (field missing from updateData iteration). New
  V1PatchCustomerSchema extends UpdateCustomerSchema with archived_at
  restricted to literal null — agents can un-archive but cannot fake
  archive timestamps. The PATCH allowlist now includes archived_at.

Defensive cleanups:
- POST: VIES validation now resolves BEFORE the insert so
  vat_number_validated is set atomically in the primary write. Eliminates
  the stale-response window where the response could show
  vat_number_validated=false even though the secondary update succeeded.
- PATCH: same pattern — VIES re-validation folded into the primary
  update payload. Single round-trip; response always reflects committed
  DB state.
- CUSTOMER_RESPONSE_COLUMNS dropped vat_number_validated_at (internal
  timestamp; not declared in the CustomerCreated or CustomerDetail Zod
  schemas; no documented consumer).

Pushing back on:
- V8.2.1 cross-tenant membership check — false positive. The wrapper
  performs the company_members check before invoking the handler
  (lib/api/v1/with-api-v1.ts ~232). The swarm read handlers in isolation.
- A.8.11 PATCH response masking for individual customer_types —
  deliberate detail-endpoint carve-out per PR-A. List masks, detail
  doesn't; that's the design.
- CC6.3 separate customers:delete scope — every accounting API
  (Stripe, QuickBooks, Fortnox) conflates write + archive. Splitting
  violates principle of least surprise.
- V4.5 schema allowlist enforcement — Zod already strips unknown keys;
  defense-in-depth at the DB-write layer is redundant.
- A.5.34 eu_individual masking documentation — the value never existed
  in canonical CustomerTypeSchema; PR-A's enum was a hallucination this
  PR corrects. Nothing to document beyond the code comment that's now
  in place.
- Swedish: country default 'Sweden' wrong for non-Swedish customer types —
  breaking schema change; defer.
- Swedish: VAT-format regex pre-check before VIES — internal
  /api/customers route doesn't either; consistency over micro-validation.
- Swedish: flag existing reverse-charge invoices when VIES turns
  vat_number_validated=false — substantial cross-resource workflow;
  defer to PR-B-2 or a dedicated compliance-tooling PR.
- CC7.2 customer.updated / customer.archived event emission — adding new
  event types touches lib/events/types.ts AND the event-log-handler
  allowlist; defer to PR-C where webhooks will be the consumer.

3 new tests cover: archive-blocked-by-open-invoices, PATCH archived_at
un-archive, PATCH archived_at rejects non-null. 3153/3153 vitest pass;
build clean.

* fix(api): second-pass review on PR #452 — defense-in-depth tweaks

Two small adjustments after the second compliance-swarm sweep (13 →
expected 11 findings, 0 blocking after this commit):

- GDPR Art.5(1)(c) defense-in-depth: re-add 'eu_individual' to the
  INDIVIDUAL_TYPES masking set in the customer LIST handler. The value
  is not in the canonical CustomerTypeSchema (so new customers can never
  have it), but the `customer_type` DB column carries no CHECK constraint,
  so legacy rows from earlier schema iterations could in principle hold
  it. Masking is free when the value never appears and protective if it
  ever does. Adding 'eu_individual' as a first-class customer_type for
  EU natural persons remains a separate product decision the Swedish
  compliance review surfaced.

- ISO 27001:2022 A.8.33: test bootstrap now asserts NODE_ENV === 'test'.
  Supabase clients are fully mocked, but if a future test refactor
  accidentally bypassed the mock, this guard fails the run rather than
  letting fixtures reach production.

Stale comments from prior sweep — no action needed, fixes already in
commit 5bb63489:
- Greptile P1 "DELETE doesn't check open invoices" — handler now does
  (lines ~430-440 of [id]/route.ts); the inline comment is pinned to
  the original file lines and hasn't auto-resolved.
- Greptile P1 "PATCH archived_at silently ignored" — V1PatchCustomerSchema
  now accepts archived_at: z.null().optional() and the field is in the
  iteration list.
- Greptile P1 "example uses old enum" — updated to 'swedish_business'.

False positive called out:
- OWASP V2.4 "dry-run DELETE skips the open-invoice pre-check" — the
  pre-flight runs BEFORE the dry-run branch ([id]/route.ts ~430-445),
  so dry-run DELETE on a customer with open invoices DOES return 409.

Pushing back (consistent with first-pass triage):
- V8.2.1 × 3 cross-tenant check — wrapper does it (with-api-v1.ts ~232);
  false positive.
- V2.3 / CC6.3 archive scope split — every accounting API conflates
  write + archive.
- V4.5 customer_type cross-field invariants — schema-level cross-field
  validation; defer.
- V16 transactional outbox — architectural; defer to PR-C webhooks.
- Art.25 + A.5.12 + A.5.34 PATCH/dry-run preview masking — single-record
  detail context, deliberate carve-out per PR-A.
- Swedish 'disputed' status — not in canonical InvoiceStatus enum.
- Swedish 3-state VIES validation, personnummer-format check, mandatory
  country for non-SE types — all schema-level / cross-field; defer.

3153/3153 vitest pass; build clean.

* fix(api): don't echo org_number in 409 conflict response (GDPR Art.5(1)(c))

For customer_type='individual', org_number IS the Swedish personnummer.
The 409 CUSTOMER_DUPLICATE_ORG_NUMBER error detail previously included
the submitted value, transmitting it through:
  - The HTTP response body
  - Server / observability logs
  - Any HTTP intermediary recording bodies

The caller already knows what they submitted; the error code + a
{ field: 'org_number' } hint is enough. Drops the value from the detail
in both POST /customers and PATCH /customers/:id.

3153/3153 tests still pass.

Jakob WennbergandClaude Opus 4.7 32ad6da28c feat(api): v1 invoice + customer reads (Phase 2 PR-A) (#451)
* feat(api): v1 invoice + customer read endpoints (Phase 2 PR-A)

First slice of the Phase 2 invoices vertical. Read-only endpoints landing
in this PR; writes + webhooks land in PR-B and PR-C. After all three a
developer can ship an end-to-end invoicing integration.

New endpoints (all wrapped, scoped, cursor-paginated):
- GET /api/v1/companies/:companyId/invoices       — list, filters: status, customer_id, document_type, currency. Cursor on (invoice_date DESC, id DESC). Customer name embedded inline; ?expand=customer for full record, ?expand=items for line items.
- GET /api/v1/companies/:companyId/invoices/:id   — detail with embedded customer. ?expand=items,payments.
- GET /api/v1/companies/:companyId/customers      — list, filters: customer_type, search (name/org_number prefix), include_archived. Cursor on (created_at ASC, id ASC).
- GET /api/v1/companies/:companyId/customers/:id  — detail. ?expand=invoices embeds open invoices in a single round-trip.

Shared infra:
- lib/api/v1/expand.ts — parseExpand() validates ?expand=a,b,c against a per-endpoint allowlist; unknown keys yield VALIDATION_ERROR with the full invalid list and the allowlist (agent-friendly).
- All four routes register with the Zod schema registry so they show up in /api/v1/openapi.json with x-action-risk and use-when / do-not-use-for metadata.
- Compound keyset filter on both list endpoints (per Greptile review on PR #450) — no skipped or duplicated rows on page boundaries.

Tests:
- lib/api/v1/__tests__/expand.test.ts (8 tests)
- app/api/v1/companies/[companyId]/invoices/__tests__/route.test.ts (10 tests)
- app/api/v1/companies/[companyId]/customers/__tests__/route.test.ts (8 tests)

Full repo suite green (3127/3127), build clean, lint clean on v1 paths.

* fix(api): address PR #451 review (Greptile + compliance swarm)

- Greptile P1 (customers search) + OWASP V1.2.5: customer search term now
  escapes both PostgREST .or() delimiters (,()) AND SQL LIKE wildcards
  (% _ \). '100%' searches for the literal string instead of any
  customer containing '100'.
- OWASP V8.2.1 + V16.1: detail endpoints now UUID-validate the :id path
  param before touching the database, and no longer echo the raw id in
  the NOT_FOUND response details. Adds a structured warn log on 404 with
  the queried (id, companyId) for audit purposes.
- V4.5 + Art.25(1) + A.8.3 / A.8.11 + CC6.3 + PI1.3 (~12 findings): every
  select('*') replaced with explicit column lists per the documented Zod
  schemas. Includes joined sub-queries — customer:customers(...),
  items:invoice_items(...), payments:invoice_payments(...). Future
  schema migrations adding sensitive columns must now update these
  projections before the field becomes visible on the public API.
- A.8.5: hardcoded 'Bearer gnubok_sk_x' in test fixtures replaced with
  'Bearer test-fixture-not-a-real-key' to avoid false-positive secret
  scanner alerts. Fixture UUIDs upgraded to valid v4 format (Zod 4's
  .uuid() enforces version+variant digits).
- Art.5(1)(f): customer-invoices expansion soft-degrade now logs only
  the error code + message rather than the full Supabase error object.

Pushing back on:
- Art.5(1)(b) org_number in customer list — Bolagsverket-public data
  (same triage as PR #450; required by integration use case)
- Art.25(2) customer_name always-joined — denormalising via trigger is
  a real schema migration for a marginal data-flow gain
- A.8.15 _partial flag on soft-degrade — ?expand is documented as a hint

50/50 v1 tests; 3131/3131 full suite; build clean.

* fix(api): second-pass review on PR #451 — partial_expansions + fake fixtures

Address the residual compliance-swarm findings after the first fix round:

- CC6.1 (medium): the customer-detail handler now sets
  meta.partial_expansions=['invoices'] when the ?expand=invoices subquery
  fails, signalling the degraded response to the caller without escalating
  to error-level logs (alert fatigue). The primary resource still returns
  with an empty invoices array. New ResponseOptions.partialExpansions
  threaded through buildMeta(). 1 new test for the failure path, plus
  a happy-path assertion that the flag is absent.
- A.8.33 (low): SAMPLE_CUSTOMER fixture's org_number and vat_number
  replaced with 'TEST-0000-0001' / 'SETEST00000001' — cannot be confused
  with real Bolagsverket entries or pass external VIES validation.

Pushing back on:
- CC6.3 (medium) — separate scope for ?expand=items on invoices: every
  accounting API I know (Stripe, QuickBooks, Fortnox) treats line items
  as part of the invoice resource. Splitting would violate principle of
  least surprise for integrators; the plan deliberately treats
  invoices:read as covering the full invoice including items.

3132/3132 vitest pass; build clean.

* fix(api): third-pass review on PR #451 — PII minimisation refinements

Third compliance-swarm sweep (6 → 0 highs, 4 medium, 2 low). Addressed:

- Art.5(1)(c) personnummer leakage: customer LIST response now masks
  org_number AND vat_number for customer_type IN ('individual',
  'eu_individual') — for sole traders (enskild firma) org_number IS the
  personnummer. Business customers' Bolagsverket-public org_numbers stay
  visible. Detail endpoint (deliberate single-record fetch) unchanged.
- Art.5(1)(c) over-broad invoice-list expansion: ?expand=customer on
  the invoice LIST endpoint now uses a new CUSTOMER_LIST_CONTEXT_COLUMNS
  projection (id, name, customer_type, email, country, archived_at) —
  full address/phone/notes/vat_number stay on the customer DETAIL
  endpoint. Drops PII transmitted in bulk-list contexts by ~60%.
- A.8.15 permission-error differentiation: customer-detail soft-degrade
  for ?expand=invoices now bumps Postgres error class 42 (insufficient
  privilege, RLS denial) to error-level log so Sentry alerts on
  misconfigurations. Transient errors stay at warn.
- PI1.1 ISO-4217 currency: invoice list ?currency now requires
  /^[A-Z]{3}$/ instead of accepting any 3-8 char string. Two new tests.

Pushing back on:
- Art.5(1)(f) UUID logging on 404 — UUIDs have 122 bits of entropy; you
  cannot enumerate the space, so the "log scraping = enumeration" framing
  doesn't hold. Operational audit value > theoretical risk.
- Art.25(1) notes-by-default in customer DETAIL — kept inline. Detail
  is a deliberate single-record fetch; the dashboard shows notes inline;
  agents calling /customers/{id} reasonably expect them. Notes are
  already excluded from the LIST endpoint AND from the invoice-list
  ?expand=customer projection (above).

3135/3135 vitest pass; build clean.

Jakob WennbergandClaude Opus 4.7 db592d922d feat(api): v1 REST API foundation — auth wrapper, scopes, registry, smoke endpoints (#450)
* feat(api): v1 REST API foundation — auth wrapper, scopes, registry, smoke endpoints

Lay the substrate for the public REST API at /api/v1/*: Bearer-auth wrapper
that reuses the existing api_keys + idempotency machinery, an extended scope
catalogue (companies, events, webhooks, operations, documents, compliance),
v1 response envelopes (data + meta with request_id, api_version, audit block,
cursor pagination), an error envelope with recovery_hint / docs_url /
valid_alternatives derived from the existing structured-error registry, and
a Zod schema registry that generates the OpenAPI 3.1 spec with x-action-risk
/ x-idempotent / x-reversible / x-dry-run-supported extensions.

Ships discovery routes (/llms.txt, /.well-known/skills/index.json) and three
smoke endpoints (GET /api/v1/health, /api/v1/companies, /api/v1/openapi.json)
so the wrapper is exercised end-to-end. Includes the api_keys.mode (test|live)
migration and 41 unit tests covering auth, scope, company-membership,
idempotency replay, dry-run, pagination, response shape, and scope resolution.

* fix(api): harden v1 foundation — cursor validation, security headers, forensic logs

Address compliance-swarm findings on PR #450:

- OWASP V2.3: decodeDefaultCursor now validates the cursor's ts as ISO 8601
  and id as UUID. A crafted cursor previously could inject untyped strings
  into a query's .gt(field, value); PostgREST would have rejected them, but
  validating here keeps the failure mode predictable (stale cursor → reset)
  rather than 400-ing.
- OWASP V3.4: public discovery routes (llms.txt, .well-known/skills,
  openapi.json) now stamp X-Content-Type-Options: nosniff, Referrer-Policy,
  X-Frame-Options: DENY. New lib/api/v1/security-headers.ts helper.
- OWASP V16: security event logs (missing token, validation failure,
  insufficient scope, company-membership deny) now include source IP
  (x-forwarded-for / x-real-ip) and User-Agent for forensic correlation.
- OWASP V8.2.1 / ISO A.8.3: GET /api/v1/companies emits a warn log when the
  PostgREST archived_at filter unexpectedly returns a row with a null
  company join, surfacing silent data-integrity regressions instead of
  hiding them behind the existing pickCompany() === null filter.

Pushing back on (not changed):
- GDPR Art.32 cursor HMAC signing — cursors only paginate within a user's
  own user_id scope; cross-tenant probe surface doesn't exist yet.
- GDPR Art.25 org_number in list — Bolagsverket public-record data, removing
  forces N+1 fetches to make the response useful.
- SOC 2 CC6.3 service-role bypasses RLS — defense-in-depth IS the design;
  the wrapper's company_members membership check is the technical control.
- ISO A.8.12 public OpenAPI spec — intentional, mirrors Stripe/Twilio.

5 new pagination tests cover the cursor validators. 46/46 v1 tests pass.

* fix(auth): detect Supabase duplicate-signup obfuscation on register

Supabase obfuscates duplicate signups to prevent user enumeration: when an
email already belongs to a confirmed account, signUp returns data.user with
identities: [] and no error, and sends no email. Without detecting this case
we showed the "check your email" screen to the user, who then waited for a
mail that never arrived.

Detect the empty-identities response and surface it via duplicateEmail state
so the UI can branch on it.

* fix(api): second-pass hardening — CSP, IP truncation, cursor scope comment

Address the second compliance-swarm sweep on PR #450:

- OWASP V3.2: PUBLIC_SECURITY_HEADERS now includes Content-Security-Policy
  default-src 'none'; frame-ancestors 'none'. Free win for JSON/text-only
  public routes (no script, style, image, or form contexts).
- GDPR Art.5(1)(f): truncate IPs before logging — IPv4 to /24, IPv6 to /48.
  Preserves diagnostic value (ASN, abuse-pattern correlation, city-level
  geolocation) while eliminating point-of-presence identification. Standard
  pattern used by Google Analytics anonymize_ip. Exported truncateIp() so
  other surfaces can adopt it.
- OWASP V8.2.1: explicit comment in GET /api/v1/companies documenting that
  the cursor's joined_at is applied AFTER user_id filter, so a tampered
  cursor can only reorder rows the caller already owns. Cursors deliberately
  unsigned; trade-off documented.

Pushing back on second-pass findings (not changed):
- ISO A.8.12 / SOC 2 CC6.3 health/llms.txt/skills exposing service name +
  API version + MCP URL — these are intentional disclosures for a public
  3rd-party developer API; hiding them is theatre.
- GDPR Art.32 logging granted scopes on INSUFFICIENT_SCOPE — diagnostic
  value during incident response outweighs the theoretical privilege-profile
  leak; an attacker who already breached the log store has bigger problems.
- OWASP V2.2 route-level Zod for cursor — decodeDefaultCursor already
  validates strictly; route-level Zod is stylistic.
- GDPR Art.25(2) org_number/entity_type in list — Bolagsverket-public data;
  entity_type materially affects which API calls make sense.
- ISO A.8.15 x-forwarded-for trusted-proxy CIDR — overkill behind Vercel's
  edge which rewrites the leftmost value.

50/50 v1 tests pass (4 new for truncateIp). Build green.

* fix(api): third-pass hardening — Host header injection, anon client, HSTS

Address the third compliance-swarm sweep on PR #450:

- SOC 2 CC6.1 (3× high): llms.txt, openapi.json, and .well-known/skills
  built URLs from the inbound Host header. A spoofed Host could poison
  agent discovery with attacker-controlled endpoints. New
  lib/api/v1/base-url.ts centralises canonical base-URL derivation via
  NEXT_PUBLIC_APP_URL (already a required env var per CLAUDE.md).
- ISO A.8.2 / A.8.5 (2× high): the wrapper's public-scope code path now
  uses an anon-key Supabase client (RLS-respecting) instead of the
  service-role client. A future accidental DB call from a public handler
  is constrained to anon-accessible rows. Least-privilege at the
  infrastructure layer.
- OWASP V3.2 (medium): PUBLIC_SECURITY_HEADERS now includes
  Strict-Transport-Security: max-age=31536000; includeSubDomains.
- GDPR Art.5(1)(f) (medium): truncateIp now logs a warn when a non-empty
  x-forwarded-for / x-real-ip payload fails to parse, surfacing spoofed
  or unexpected proxy values to security monitoring instead of silently
  dropping them. The raw value is never logged.
- CC2.3 (low): llms.txt now links the SECURITY.md disclosure policy with
  the security@arcim.io reporting address so agents have a clear
  responsible-disclosure path.

Pushing back on third-pass findings (not changed):
- Cursor HMAC signing — user_id filter is the authorisation boundary;
  cursor scope is bounded to within-user rows. Documented in code.
- org_number in companies list — Bolagsverket public data; the swarm's
  "could be enskild firma personnummer" framing isn't accurate (enskild
  firma org_number IS the personnummer, but it's already in the public
  Bolagsverket business register).
- Health endpoint information disclosure — intentional for a public
  developer API; matches Stripe/Twilio convention.
- llms.txt / skills index MCP URL disclosure — that's the file's purpose.
- Cache-Control public on discovery routes — content is by definition
  public; getCanonicalBaseUrl() removes the previous spoof concern.
- Duplicate-email screen — user's own input; out of scope for this PR.

50/50 v1 tests pass; @supabase/supabase-js#createClient mocked so the
public-path tests don't need real env vars.

* fix(test): widen validateApiKey result assertions to include mode field

The core-only CI job failed on two pre-existing api-keys.test.ts assertions
that used strict toEqual matching against the old (userId, companyId, scopes)
shape. The wrapper migration in this PR widened that shape with mode,
apiKeyId, and apiKeyName.

Update both existing assertions to match the current shape and add a third
test that exercises the mode='test' path. 3027/3027 vitest tests now pass
locally.

* fix(api): fourth-pass hardening — env guards, IP range check, headers on wrapped routes

Address the fourth compliance-swarm sweep on PR #450:

- ISO A.5.17 / SOC 2 CC6.1 (high): createAnonClient now fails closed with
  an explicit Error if NEXT_PUBLIC_SUPABASE_URL or _ANON_KEY are missing,
  surfacing misconfiguration on the first request instead of throwing
  deeper in the handler with no context.
- GDPR Art.5(1)(f): truncateIp now rejects IPv4 with out-of-range octets
  (>255). '999.999.999.999' now returns undefined instead of a pseudo-IP
  that would pollute abuse-pattern analysis. Edge octets (0, 255) still
  accepted. 2 new tests.
- OWASP V3.2 / V3.3: the wrapper's stampHeaders step now applies the full
  security header set to every wrapped v1 response (CSP, HSTS, X-Frame,
  Referrer-Policy, X-Content-Type-Options) PLUS X-Robots-Tag: noai,
  noimageai so authenticated payloads are excluded from AI training sets.
  Public discovery routes (llms.txt, skills index, openapi.json)
  deliberately omit X-Robots-Tag — being AI-discoverable is the whole
  point of those surfaces.
- New WRAPPED_RESPONSE_HEADERS export separates the two contexts.

Pushing back on:
- SOC 2 CC6.1 medium "API key prefix in public docs aids brute force" —
  inverted logic. Every public API publishes its key prefix specifically
  so secret scanners (GitHub Advanced Security, GitLeaks) can detect
  leaks. Stripe (sk_live_), GitHub (ghp_), OpenAI (sk-) all do this.
- SOC 2 CC6.3 medium "formal risk register for unsigned cursors" — org
  -level documentation, outside this PR. Code-comment already documents
  the trade-off.
- SOC 2 CC2.3 low "llms.txt hardcodes security@arcim.io" — same address
  as SECURITY.md; no drift risk.

Flagged separately (not changed): the register-page duplicate-email
detection in this branch defeats Supabase's user-enumeration obfuscation
(GDPR Art.5(1)(c) × 2, ISO A.8.11). Substantive product decision: UX (no
infinite-wait for non-existent accounts) vs security (no enumeration).
GitHub and Stripe Atlas pick UX; some pick security. Owner's call.

3029/3029 vitest tests pass.

* fix(api): address Greptile review on PR #450

- P1 (companies/route.ts): keyset pagination was missing its tiebreaker.
  The cursor encoded (joined_at, id) but the filter only applied
  .gt('joined_at', ts) — same-joined_at rows on a page boundary could be
  skipped or duplicated. Also the encoded id was companies.id while the
  sort was on company_members, mismatched. Fixed: select + sort + encode
  on company_members.id, apply compound
  joined_at.gt.{ts} OR (joined_at.eq.{ts} AND id.gt.{cursor_id}) via .or().
  Side benefit — eliminates the broken-cursor-on-null-join case (#2)
  because company_members.id is always present, no null guard needed.
- P2 (registry.ts): ZodUnion branch had a dead ternary
  (['x','y','z','w'].length > 0 ? undefined : 'object') that always
  yielded undefined. Removed; emit { oneOf: [...] } without top-level
  type (correct JSON Schema for a union).
- P2 (with-api-v1.ts): public-endpoint path was short-circuiting before
  Bearer-token validation, contradicting the JSDoc and PR description.
  Now opportunistically validates a supplied token for rate-limit
  attribution + key tracking; missing/invalid token silently falls back
  to anon (the route is public by definition, so we don't 401). Two
  new tests cover both branches.

3031/3031 vitest tests pass; build green.
