fix(security): audit remediation 2026-09-01: api_keys identity, viewer gates, OAuth binding, XSS, MFA gate (#2155)
* fix(security): bind api_keys to the caller, lock hash-as-bearer RPCs and provider token tables Security audit 2026-09-01, critical items. - api_keys INSERT requires user_id = auth.uid() again (an admin could forge a key for any co-member and act as them in every company they belong to); SELECT is own-keys-or-admin; a BEFORE trigger freezes the identity and credential columns against user-session UPDATEs. - rotate_mcp_refresh_token and validate_and_increment_api_key become service_role only: they match rows by a presented SHA-256, so a hash readable by co-members was a bearer credential. - validate_and_increment_api_key fails closed when the key's user is no longer a member of the key's company. - provider_consent_tokens and provider_otc: the DELETE policies collapsed to "caller has any team row" (correlated subquery on a non-existent team_members.company_id). All member policies dropped; service_role only, matching every existing code path. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(security): role gates, ownership guards and posting integrity in the database Security audit 2026-09-01, high items at the database layer. - One table-level guard, enforce_company_writer_role(), blocks the read-only viewer role on 55 company-scoped tables including through the 15 membership-only SECURITY DEFINER writers. Keyed on the JWT role claim so it fires inside definer bodies; no-op for service_role and trigger cascades. - company_members user_id/company_id immutable from user sessions; invitations can never grant owner; team_members gains a transition guard (admins keep non-owner role moves); companies team_id and archiving are owner-only and team attachment needs team membership. - Direct statements (current_user = authenticated) can no longer insert posted headers, add lines under posted verifikat, or post a draft with a voucher number the sequence never issued. Sanctioned RPCs run as the definer and are untouched; the engine's own draft-then-post shapes still pass. - create_document_version refuses viewers and foreign storage paths; validate_version_chain needs membership and loses anon EXECUTE; match_documents / match_booking_templates lose anon; cron maintenance RPCs become service_role only; the production-only seed_asset_categories is dropped. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * build: pin tsx as an exact devDependency instead of fetching it with npx at build time prebuild ran "npx tsx" with no lockfile entry, so every Vercel, Docker and CI build downloaded tsx@latest and its transitive tree from the registry with no integrity check, inside the build environment. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(security): refuse the viewer role on API-key and MCP write paths The v1 wrapper and the MCP company routing checked company membership but never role, and both run as service role, so a read-only viewer holding an API key could post vouchers and change settings through the API. Mutating methods and non-read scopes now return 403 ROLE_READ_ONLY for viewers on v1; MCP write tools refuse viewers the same way. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(security): stop serving uploaded SVG, XML and HTML as executable content on the app origin Uploads persisted the browser-declared mime type and the inline proxy served it verbatim, sandboxing only text/html; the storage proxy forwarded the uploader's Content-Type. Any writer, or any Peppol sender, could plant a scripted SVG or XHTML that executed on app.gnubok.se. - inline route: allow-list of natively safe types (PDF, raster images) served as before; everything else gets the opaque sandbox CSP. - storage proxy: octet-stream + attachment + sandbox unless the DB mime for the key is on the allow-list. - document-service: the stored mime is the magic-byte validated type. - logo upload: magic-byte validation, SVG refused. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(security): byrå brand logo upload decides the type by magic bytes and drops SVG Same pattern as the company logo route: the logos bucket is public, so a scripted SVG (or anything declared as an image) must never land there. The upload pickers stop advertising SVG. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(security): bind Enable Banking, Stripe and WooCommerce callbacks to the initiating user The callbacks resolved the pending row by oauth_state alone, so a victim who completed an attacker-initiated consent had their bank account, merchant account or store attached to the attacker's company. requireFlowInitiator() now requires the cookie session of the user who started the flow: no session redirects to login with the callback URL preserved, a different user is refused and nothing is exchanged. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(security): guard tenant-controlled outbound fetches and surface the disabled rate limiter WooCommerce and Shopify syncs fetched a member-editable store URL with plain fetch() and redirect following under the service role, and the invoice PDF renderer fetched company_settings.logo_url unguarded. All three go through a new safeFetch() (public-IP validation via url-guard, https only, redirect: 'manual', body size cap) and re-normalise the stored host at use time. checkRateLimit() keeps failing open on hosted but logs one error per process when Upstash is not configured and exports isRateLimiterConfigured(). Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(security): decide the API MFA gate from server-authenticated factors, not the session cookie getAuthenticatorAssuranceLevel() without arguments derives nextLevel from session.user.factors, which comes from the unsigned sb-*-auth-token cookie. Deleting factors from the cookie made an enrolled account look like it had nothing to step up to, on every /api route and in requireAuth. Both gates now read factors from the getUser() result or listFactors() and the level from the verified JWT claim, and fail closed on errors. Page-branch gate hardened the same way. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(security): bind Fortnox/Visma, Gmail and Skatteverket callbacks to the initiating user The arcim-migration callback exchanged the provider code onto whatever consent the one-time state named, with no check of who completed the flow and no org-number comparison, so a phished Fortnox admin handed their ledger to the attacker's company. provider_otc now records the initiating user (migration 20260902100000); the callback requires that session and, after the exchange, refuses a provider company whose org number differs from the consent's company. The Gmail and Skatteverket callbacks enforce the same initiator check. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(security): BankID signup confirms the email before linking the identity Signup created an email-confirmed, MFA-exempt account for any address the caller typed and returned a magic link, so an attacker could pre-register a victim's email and keep a permanent BankID login into the account the victim later adopted. The user is now created unconfirmed, the identity carries email_verified_at NULL (migration 20260902101000), bankid_linked is not set until the mailed confirmation is clicked, and BankID login of a pending identity is refused with the confirmation re-sent. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(security): bind MCP OAuth redirect URIs to the consenting user and cap scopes A user-registered redirect URI was allowlisted globally, the consent page named no client, and all scopes were pre-checked, so one phishing link handed an attacker a full-scope key for the victim's company. Registered URIs now resolve only for the registrant or a colleague sharing a company; the consent page shows the client identity and redirect host; non-built-in clients default to read-only pre-checks; scopes are capped by the user's role (viewer: read only) at consent and at /token. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(auth): client follow-ups for BankID confirmation, callback mismatch copy and decision log - register client handles the new confirmation_sent response from BankID signup with the existing inbox screen instead of calling verifyOtp. - BankID login surfaces the email_unconfirmed explanation. - WooCommerce settings map woocommerce_error=wrong_user to its own copy. - Logo help text no longer advertises SVG. - DECISIONS.md records the audit remediation choices. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * fix(mcp-oauth): literal SoD columns in the api_keys insert so the phantom-column scanner resolves them Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * test(logo): type the upload fixtures as Uint8Array<ArrayBuffer> so they are valid BlobParts Fixes the typecheck ratchet on PR #2155 and ratchets the baseline down by the one legacy error the change removed.

feat(billing): multi-user paywall: multi_user capability, 20-day grace, owner-only dormancy (#2099)
* feat(billing): multi-user seat gate: multi_user capability, 20-day grace, owner-only dormancy Multiple people in one company becomes a paid capability (multi_user, the eighth PAID key). Derived at access time from capability_grants, no status column, no enforcement cron: - entitled: active grant (trial/stripe/team/manual/comp), everyone works - grace: newest grant expired < 20 days ago; countdown banner for everyone in companies with > 1 user; invites still allowed - frozen: only role=owner resolves; other memberships go dormant (rows untouched, paying reactivates instantly); invites 403 with paid-plan upsell Enforcement: new resolve_active_company_gated RPC (zero-arg RPC and RLS twin untouched: they also run on self-hosts, where the gate never bites), gated query fallback for service-role/API-key paths, setActiveCompany guard, MCP company-access check, invite route. Middleware routes all-frozen users to a new /paused page; the switcher greys locked companies. Migration 20260901081417 (applied to staging): trial trigger seeds multi_user, backfills for mid-trial companies, active Stripe subs, team agreements, and a grandfather grant (expires now, i.e. grace = deploy + 20 days) for existing unpaid multi-member companies. Daily cron mails owners at grace start and last day. Strings in sv+en; pg-real + unit tests included. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01L4tNt8wRG3a5iuU1JE2pnP * fix(billing): multi-user seat gate hardening from skeptic review - Stripe cancel now EXPIRES the multi_user stripe grant instead of deleting it: the 20-day grace window hangs on an expired row, so a deleted one froze churned payers' staff instantly with no banner and no mail. Other stripe grants keep the freeze-and-retain delete. - New SECURITY DEFINER company_multi_user_state() RPC (migration 20260901083726, applied to staging) and RPC-first getMultiUserState: capability_grants RLS hides team-scoped rows from non-team users, so user-client reads misread byra-covered companies as frozen (switch refusal, wrong switcher locks). - Byra-kind teams get a standing team-scoped multi_user grant (backfill + teams trigger): byra client companies have no company-scoped trial by design, so a grantless byra team would freeze every consultant and client user. - Comped/manual companies with active PAID-key grants extend to multi_user (a comped company must not read as paying while locking out user two). - /api/v1 gets the same dormancy gate as MCP (frozen non-owner -> 403). - PGRST202 on resolution fails OPEN (pre-migration DB has zero multi_user rows; the gated fallback would have frozen every non-owner mid-deploy). - Grace cron: covers team-scoped lapses (byra agreement ending) and skips the start mail for the hand-mailed grandfather cohort. - Tests updated/added across all touched surfaces; pg tests for the new RPC and byra trigger; trial-suppression pg test extended to 8 keys. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01L4tNt8wRG3a5iuU1JE2pnP * fix(billing): decouple seat-gate env check and fail open on gate read throws CI round 1 on #2099: - isMultiUserEnforced no longer imports has-capability: several route test suites partially mock that module and the vitest mock guard threw from inside the v1 seat gate, turning expected 4xx responses into 500s. multi_user is never a connector capability, so the bypass reduces to the same env reads, now inlined. - getMultiUserState wraps its resolution in a fail-open try/catch: a client without .rpc or a thrown network error must never lock users out. - no-phantom-columns ceiling 391 -> 393 with reasons: the seat gate's .or() scope filter (server-resolved UUIDs) and the Stripe cancel expiry update's timestamp .or(); all columns in both strings are literals. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01L4tNt8wRG3a5iuU1JE2pnP * fix(billing): membership-guard the multi-user entitlement RPCs (Superagent P3) company_multi_user_ok and company_multi_user_state are SECURITY DEFINER and were granted to authenticated with a caller-supplied company UUID: any logged-in user could probe an arbitrary company's billing state and grace deadline across tenants. Migration 20260901091752 (applied to staging) requires an auth.uid() membership in the target company when a JWT is present, keeps service-role/definer contexts unrestricted, and clamps the grace window to [0, 20] days. pg tests: stranger gets false/NULL, member reads normally, oversized p_grace_days cannot widen the probe.

feat(api): agent-substrate quick wins: worked examples in the spec, honest Retry-After, and a payload guard that covers the namespace new installs get (#1974)
* feat(api): surface the registry's worked examples in the OpenAPI spec and generated skill EndpointDefinition.example is required and every one of the 125 v1 endpoints populates example.response, but generateOpenApiSpec() never emitted it. The examples reached only the docs markdown builder, so /api/v1/openapi.json carried none and the generated skills/accounted-api had zero json blocks in all 12 reference files: every agent reading the spec or installing the skill got schemas with no concrete body. Emit example on the application/json media types (request body and 200 response) and teach the portable renderOperationMd to print it as a fenced json block. 178 worked examples now reach the skill. SKILL.md is unchanged: the examples land in the on-demand reference files, not the entry file. Attached to JSON media types only, so a multipart body and a binary application/pdf response do not advertise an example they cannot send. Adds the one missing example.request (currency-revaluation) so the new exhaustive coverage assertions hold. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(api): emit Retry-After on a v1 429 so the documented contract is real The published accounted-api skill has told agents to honor Retry-After on a 429 since it shipped, but no /api/v1 route ever sent one: the wrapper's auth failure path early-returns through v1ErrorResponseFromCode, whose finalize() set only X-Request-Id and Gnubok-Version. Unattended clients had nothing to pace against and had to back off blindly. 60 seconds is an exact upper bound rather than a guess: the rate limiter is a fixed one-minute tumbling window per key row and the limited branch does not slide it. The value moves into an exported constant next to that limiter, so the MCP server's hardcoded '60' now reads from the same place. Also corrects the withApiV1 doc comment, which claimed step 8 stamps X-RateLimit-Limit. It never did. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(mcp): guard the tools/list payload for the namespace new installs get The payload ratchet only ever serialized the gnubok_* projection. The accounted_* projection is inherently larger (every tool reference gains 3 chars, ~209 tokens across the default catalog) and CLAUDE.md points new MCP installs at exactly that namespace, so the payload a new user's client receives was never measured. It had already drifted ~90 tokens past the 63.4K ceiling while the guarded number sat comfortably under it. Measure both and assert on the larger. The ceiling moves to 63.6K to cover the real worst case; this buys no new catalog surface. A second test pins the direction of the delta so Math.max cannot silently stop describing reality.

style: remove em/en dashes repo-wide, add CLAUDE.md rule against them (#890)
Em dashes (—) and en dashes (–) had spread across comments, docs, tests, and a few UI strings, reading as AI-generated boilerplate rather than house style. Replaced each with punctuation matching its context: colon for explanatory clauses, comma for asides, plain hyphen for numeric/legal ranges (e.g. "21-23§"), "to"/"till" for date ranges, parentheses for paired-dash asides. messages/en.json and messages/sv.json were fixed by hand together to keep sv/en in sync. Left untouched where the dash is the functional subject rather than decorative punctuation: date-range-parser.ts's separator regex, charset-repair.ts's CP1252 byte-mapping table (and its test), the SIE encoding mojibake docs, generic-csv.ts's minus-sign normalizer, the agent system-prompt files that already instruct against em dashes, and a golden iXBRL test fixture compared byte-for-byte. Also fixes two bugs surfaced along the way: an off-by-one in ApiKeysPanel's scope-label split (a leftover from an earlier partial pass), and a charset-repair test that had lost the literal en-dash it exists to verify. Regenerated the agent atom seed migration (skills:generate) since 27 SKILL.md files changed. Added a CLAUDE.md rule against em/en dashes, with an explicit carve-out for the functional-dash cases above. Co-authored-by: Claude Sonnet 5 <noreply@anthropic.com> |

fix(api): guard params await so static v1 routes don't 500 (#795)
Next.js 16 invokes a static route handler (no [segment]) with
{ params: undefined }. /api/v1/companies is the only authenticated static
route on the v1 surface, so awaiting params.params null-derefs and the catch
turns it into a 500 for every valid API key. Guard the await:
((await params?.params) ?? {}). Dynamic routes are unaffected. Fixes #781.

Fix/mcp and req (#753)
* feat(api): test-mode API keys force dry-run on the v1 REST API A key created with mode='test' (prefix gnubok_sk_test_) binds to the real company, but the v1 wrapper forces dry_run on every write so nothing is persisted or sent. Mutations on endpoints that can't be simulated (dryRunSupported=false or unregistered) are refused with 403 TEST_KEY_WRITE_BLOCKED — fail-closed. Reads pass through unchanged and every test-key response carries X-Gnubok-Mode: test. Live keys are unaffected (mode defaults to 'live'). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(invoices): company default "Vår referens" + per-line sales-account override Add company_settings.default_our_reference (settings form, schema, type); the invoice editor pre-fills our_reference from it on new invoices only, never overwriting an edited draft. Separately, add an optional per-line försäljningskonto (class-3) override in the editor — left blank, the engine still derives the revenue account from the VAT rate, and reverse-charge/export lines ignore the override. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(invoices): render a Swish payment QR on invoice PDFs Build the Swish "Type C" QR payload offline (no Swish API call) and embed it as a PNG in the invoice PDF payment box when Swish display is enabled, the invoice is in SEK, and the amount is positive. Also surface the invoice number in the payment box. Wired through every PDF render path: send, mark-sent and pdf routes (both legacy and v1), the recurring-schedule sender, and the staged-send commit. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(bookkeeping): draft exclusion + correction-chain collapse on verifikationslista Extend list_fiscal_period_entries_with_related with two opt-in params: p_exclude_draft (keep drafts off the committed list — they get their own surface) and p_collapse_corrections (render a correction group as the single live correction, hiding the mechanical storno and the reversed original). Both default false; nothing is deleted, every voucher keeps its number, and a "show all" toggle exposes the full chain. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(reports): link multi-year SIE periods so resultatrapport shows the prior year SIE import now sets fiscal_periods.previous_period_id in both directions when creating a period, so multi-year files chain correctly regardless of #RAR order. A backfill migration repairs periods imported before this (idempotent; only touches NULL links on first-of-month periods). generateResultatrapport falls back to the date-adjacent prior period when the chain is still null, so the comparison column works for legacy data too. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(articles): hide the VAT field for non-momsregistrerade companies The article form reads company_settings.vat_registered and, when false, hides the moms field and forces vat_rate to 0 on submit — mirroring the invoice editor so a non-VAT-registered company never sets a rate it can't charge. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(import): allow file-based imports in the sandbox Bank-file, CSV/Excel and SIE imports run entirely on uploaded data with no external service, so they're now reachable in the sandbox. Only the API-backed options that need live third-party credentials (PSD2 bank connection, provider migration) stay disabled. Updates the sandbox notice copy to match. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(bookkeeping): add edit draft functionality for journal entries * feat(database): add default "Vår referens" column to company_settings for invoicing * fix(tests): set SHOW_SWISH_ON_INVOICE to false in PDF template mocks * @ fix(payments): use roundOre for Swish amount formatting Replace naive Math.round(x*100)/100 with roundOre from @/lib/money to satisfy the antipattern guard.

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