* chore: repo-wide bloat sweep, remove dead code and fold duplicate helpers

Remove 33 dead files, ~270 unreferenced exports/types, 13 dead i18n
namespaces and 4 unused dependencies; fold byte-identical helper copies
into one canonical home each (lib/utils chunk/sleep/utcDateStamp,
lib/dates/iso, lib/invariants/uuid, lib/xml/escape, lib/reports/sru/format,
lib/pdf/number-text, lib/browser/panel-request, lib/api/v1/body +
v1ValidationError rolled out to ~55 v1 routes, booking-template schemas).

No behaviour change: v1 bodies and status codes, MCP tool schemas, DB
writes and money math are untouched. Naive ore rounding was deliberately
not swapped for roundOre; see DECISIONS.md 2026-09-02 for the full list
of things left alone on purpose.

tsc, lint, 19588 unit tests and check:guards green; antipattern baseline
ratcheted (naive-ore-round 622 -> 620, hand-rolled-invariant 115 -> 113).

* test(transactions): import RawTransaction from @/types after the ingest re-export removal

CI's type ratchet (check:types, full tsconfig) caught the one test file
that still imported the type through lib/transactions/ingest.

MattssonandClaude Fable 5 f24b26a139 fix: similar-sweep currency remediation, security hardening and v1 API fixes (#1215)
* fix(security): gate replace_sie_import behind owner/admin membership

The RPC was SECURITY DEFINER with EXECUTE granted to PUBLIC and anon, no
company_members lookup, no auth.uid() reference and no unauthorized raise,
while setting gnubok.allow_delete to disarm the BFL immutability and
retention triggers. Any caller holding a company_id and an import id could
hard delete another tenant's verifikationer. Confirmed live in production.

Applies the same fail closed owner/admin guard that undo_sie_import already
carries (migration 20260624120000), resolving the actor from
COALESCE(p_user_id, auth.uid()) so it denies when the role is NULL, then
revokes EXECUTE from PUBLIC and anon. search_path and the raised
statement_timeout are restated, since CREATE OR REPLACE drops settings that
are not repeated.

userId is a required parameter on replaceSIEImport: the service client has a
NULL auth.uid(), so a caller without an explicit actor now fails to compile
rather than hitting the closed gate at runtime.

* fix(security): validate arcim OAuth callback state server side

The callback route is skipAuth and decoded the state parameter as plain
base64url JSON, trusting consentId and provider from it. A one time code was
minted at flow start and never read. An unauthenticated attacker who learned
a consent id could run an OAuth flow on their own provider account and post
the callback with a forged state, landing their tokens on another tenant's
consent, so the victim's next migration imported the attacker's ledger.

State is now an opaque randomBytes(32) pointer to a provider_otc row,
consumed by a single atomic UPDATE guarded on used_at IS NULL and
expires_at, so a replay loses the row lock race and updates nothing.
provider is read from provider_consents rather than trusted from the client.
provider_otc already existed for exactly this purpose and was never wired up.

Also scopes getConsent to an owning company, closing a cross tenant status
oracle where the preview and migrate paths echoed a consent's status before
the scoped check ran.

* fix(security): scope documents storage to company_id (phase A)

The documents bucket policies matched on auth.uid(), and upload keys were
documents/{userId}/..., so company membership was never consulted. Removing a
member revoked nothing: their session still authenticated and they kept
direct Storage read access to every receipt, supplier invoice and bank
statement they had uploaded. The same bug was fixed for sie-files in
20260416120000; this bucket was left behind.

Phase A is additive. Company scoped policies are added alongside the
uploader scoped ones, uploads move to documents/{companyId}/{userId}/..., and
reads accept either layout so nothing breaks mid migration. Phase C, which
drops the old policies, is gated on the backfill reporting zero remaining
legacy prefix objects.

The policy compares the company segment as text rather than casting to uuid
the way sie-files does: this bucket holds keys whose second segment is not a
uuid (MCP audit packages), and Postgres does not guarantee the bucket prefix
qual runs before the cast, so a planner reordering would raise 22P02 and fail
the whole query instead of filtering the row out.

deleteDocument now removes both candidate keys. Removing only the stored
pointer would leave a readable orphan copy of a document the user asked to
erase.

The backfill script is included but has never been run. It defaults to dry
run, refuses .env.local by name, and verifies each copy is readable and
SHA-256 identical before repointing the row.

* fix(security): enforce events:read scope and membership on /api/events

This was the only one of the three validateApiKey call sites with no
downstream guard: v1 and the MCP server both check scope and re-verify
company membership, this route did neither. An events:read scope existed and
was documented as gating the endpoint but was never called, so a legacy key
falling back to DEFAULT_SCOPES read the full log. The bound company id went
straight from the api_keys row into a service role query, so a key whose user
had been removed from the company kept reading.

Adds the scope check before any database access, re-verifies company_members
with archived_at IS NULL, honours test mode by stamping X-Gnubok-Mode instead
of ignoring it, applies minimisePayload so the pull surface can never return
a wider payload than the push surface, and replaces the three flat error
strings with the canonical envelope.

Test key reads are served rather than blocked: TEST_KEY_WRITE_BLOCKED is
gated on mutations in with-api-v1, so a read gets the same treatment as every
other v1 read endpoint.

* perf(bookkeeping): sweep remaining journal_entries!inner embeds

A previous refactor removed this pattern from lib/reports and introduced
fetchEntryLines, but the class was never swept. Seventeen sites remained and
had become the top application consumer of production database time:
measured across the resulting query shapes, 32,694 calls and 25,848 seconds
of execution, mean 790ms, with shapes averaging 2.6s and 3.0s and maxing at
7,962ms against the 8s statement_timeout, which surfaced to users as 500s on
the booking path.

PostgREST compiles an embed with filters on the embedded side into a
correlated INNER JOIN LATERAL with a parameterized LIMIT, which stops
Postgres reordering the join, so each query walked the whole
journal_entry_lines table across all tenants. Driving from the entries side
instead turns that into two indexed round trips.

Converted sites keep their existing shape: the helper reattaches the parent
entry under the same key the embed produced. Several conversions also remove
a latent silent truncation where an unpaginated query was capped at
PostgREST's 1000 row ceiling.

Two deliberate exceptions. The free text ilike legs of the MCP display query
stay on the embed, because each is capped at legLimit and that cap drives the
truncation contract the tool reports, while the helper is unbounded. The
accounts route moves to the existing get_account_usage_counts RPC instead,
since its embed was a head count and the helper returns rows.

commitEntry's write path is untouched: the change there is confined to the
read query of the pre-commit dimension rule check.

* fix(api): anchor v1 list cursors on created_at

Page two returned page one, forever, while still advertising a fresh
next_cursor. The three routes sorted by and encoded a Postgres date column,
which serializes as YYYY-MM-DD, but decodeDefaultCursor validates the cursor
timestamp as full ISO-8601 and returned null, so the keyset filter was never
applied and has_more never went false. An integrator syncing verifikat looped
on the newest rows indefinitely.

The transactions route already solved this and its comment names the trap;
the fix was never ported. All three now order and encode on created_at with
an id tie break, matching the transactions keyset predicate exactly.
ISO_TIMESTAMP is deliberately left alone: relaxing it would silently change
sort semantics on the route that currently works.

Default ordering therefore moves from business date to insert order. Every
business date is still on the row, and the invoices list gains date_from and
date_to filters so a date range is still reachable; the other two already had
them.

The tests use an in-memory PostgREST that actually evaluates the filters,
because the repo's pass-through mock cannot catch this class of bug: the bug
is that the filter is never sent. They walk to exhaustion with a hard
iteration cap, so an unterminated walk fails instead of hanging.

* fix(api): separate dry run from commit in the idempotency hash

The request hash was built from url.pathname, which excludes the query
string, so a dry run and its commit hashed identically. Following the flow
documented in dry-run.ts, re-issuing the request with the same
Idempotency-Key returned the cached preview with Idempotent-Replayed set and
wrote nothing, while reporting 200. An agent or integrator saw success for a
write that never happened.

dry_run is folded into the hash only when true, not as an unconditional
boolean. Including it as false would change the hash of every ordinary write,
and with a 24h idempotency TTL any key in flight across the deploy would fail
the request_hash comparison and 409 on a legitimate retry. Both hash call
sites now go through one shared helper so they cannot drift into a permanent
cache miss, and dry run responses are no longer stored at all.

* ci: install the Bedrock SDK out of tree in the compliance review

The Swedish accounting compliance gate had failed ten consecutive runs and so
was posting nothing. With --no-package-lock npm discarded the lockfile and
re-resolved the whole tree from package.json, floating @hookform/resolvers to
5.4.3, whose valibot ^1 peer conflicts with the pinned valibot 0.39.0.

Installing into the parent of the checkout resolves only that one package, so
an unrelated peer conflict can never take the gate down again. Node still
finds it because ESM bare specifiers walk up parent node_modules; NODE_PATH
would not have worked, as it is CommonJS only. --legacy-peer-deps was
rejected because it masks future genuine peer conflicts and still reifies the
full tree.

The same step's SDK version is aligned from 0.31.0 back to the 0.29.1 that
package.json and check:guards enforce after the streaming outage. That drift
went unnoticed because the pin guard only inspects package.json and the
lockfile, never workflow files.

* build(docker): generate crontabs from vercel.json

vercel.json defines 16 cron jobs; both Docker crontabs carried 9, and were
byte identical to each other. Self hosted deployments therefore never sent
recurring invoices, never dispatched webhooks and never cleaned up
idempotency keys. tax-deadlines also ran once a year on 2 January instead of
daily, and documents/verify weekly instead of daily.

Extension crons are included rather than excluded. The Dockerfile copies the
whole tree before building, so every extension cron route is compiled into
the image regardless of the enabled preset, and each returns 200 when its
extension is unconfigured, so curl -sf logs no failure. Two such entries were
already present in the crontab for extensions absent from the preset, which
settles the intent.

documents/verify is treated as drift rather than a self hosted concession:
the weekly cadence was present in the hosted crontab too, and the run is
capped at 200 documents walking a nulls-first queue, so weekly drains the
integrity queue seven times slower on a check that exists for BFL retention.

webhooks/dispatch keeps its per minute cadence, adding 1,440 requests a day
on self hosted. A gentler tick would silently stretch the first retry, since
the retry ladder opens at 60 seconds. SCHEDULE_OVERRIDES is the one line
place to change that.

A parity test asserts the path sets match minus a documented exclusion list,
and ratchets three cron routes that are currently scheduled nowhere so they
are named rather than silently rotting.

* chore(observability): add a provider agnostic error sink

There is no error tracking in this codebase: logs go to console and Vercel
retention and nowhere else, nothing alerts on the 16 cron jobs, and seven
code comments across lib, app, components and extensions asserted that Sentry
captures errors when Sentry is not a dependency. The two most recent bug
fixes on this repo were both discovered by customer email.

This adds the sink, not a vendor. No dependency is taken: the interface has a
no-op default and a registration point, so behaviour is unchanged until an
adapter is registered. Releases are tagged from the build id already inlined
by next.config.ts.

Redaction moved out of lib/logger.ts into a leaf module that both the logger
and the sink import, so there is one denylist and no path from application
data to a third party can skip the personnummer regex, including direct sink
calls that bypass the logger. That matters here because these logs carry
personnummer and financial data.

verifyCronSecret now reports its own 401s, which covers all 16 jobs without
touching a route file and catches the case where CRON_SECRET is rotated
without updating the scheduler and every job silently 401s forever. The
threshold is one failure rather than the backup alert's three: suppressing
the first occurrence is precisely how an outage stays invisible.

The seven misleading comments are corrected to describe what the code
actually does, including the two cases that still are not covered: the client
side one, since the sink is server side, and a warn level call that is not
forwarded.

* fix: remediate the 2026-07-26 similar-sweep findings across all surfaces

Resolves the ~150-finding sweep (dev_docs/similar-sweep-2026-07-26.md) with
one agent per finding; every behavioural fix carries a regression test proven
to fail at HEAD. Full status, corrections to the sweep, refusals and open
decisions in dev_docs/similar-sweep-2026-07-26-remediation-status.md.

Structural roots closed:
- resolveSekAmountOrNull(): honest SEK resolution refuses instead of booking
  1:1; four duplicated toSek closures now refuse via INVOICE_FX_RATE_MISSING
- ledger-line-amount.ts: journal_entry_lines.currency labels the document,
  not the amount; SQL pre-filter decoy proven and fixed
- sparse-patch.ts: .partial() does not strip .default() in Zod 4.4.3; the
  exploitable salary payslip-line PATCH and KPI preferences sinks fixed
- tests/schema: migration-replay phantom-column guard (13k+ refs, closed
  CHECK sets, onConflict targets); found 28 real defects, all fixed, all
  four baselines now empty
- three new ratchet guards: sek-labelled-amount, cross-extension-import,
  ungated-extension-route

Highlights: lawful VAT-rate set on all seven invoice surfaces (ML 6 kap),
RC input VAT mismatch wired on web + both MCP callers, missing-underlag
resource delegates to the shared RPC predicate, push-notifications consent
polarity fail-closed, deadlines undo honours requested state, silent-failure
and read-side-fabrication classes fixed across settings/KPI/inbox/Stripe/
Arcim/kassaflodesanalys, error-envelope stringification fixed at 10+ sites
with isSwedishUserMessage extended.

Also includes the parallel session's MCP invoice tools (update_invoice,
recurring schedules, invoice deliveries) which share files with the sweep
work and are verified green together.

13 new migrations are NOT applied anywhere; they apply via branch merge.
20260726120000 backfills 1247 supplier-invoice rows. pg tests for new
DDL are written but unrun (no local Postgres).

Verified: 11088 tests / 881 files green, tsc 0 non-test errors, lint 0
errors, check:guards passing, MCP payload 57475/57500.

* fix(migrations): rename replace_sie_import migration off main's 20260726090000 version

origin/main shipped 20260726090000_agent_quota_rpc_caller_guard.sql; keeping
our replace_sie_import migration on the same version would abort the Supabase
apply with a schema_migrations_pkey duplicate at merge time.

* fix(review): remediate pre-publish deep-review findings across all slices

A 13-agent review of the full branch diff surfaced 1 critical, 5 high and
~45 further findings; this commit resolves them in one pass:

- replace_sie_import / undo_sie_import: p_user_id honored only for
  service_role callers; any other caller is pinned to auth.uid()
  (impersonation gate bypass), authz raise errcode 42501 mapped to a
  Swedish 403 in the route, new caller-guard migration for undo
- bulk_book_transactions refuses homogeneous non-SEK batches instead of
  writing foreign magnitudes into SEK ledger columns
- credit-note cap trigger: company-match on credited_invoice_id, no
  cross-tenant figures in exception text
- link_voucher RPCs resolve NULL invoice currency as SEK end to end
- personal-number ciphertext CHECK split into NOT VALID + VALIDATE
- same-currency foreign settlements clear 1510 at booking rate and book
  realized diff to 3960/7960; rate-less foreign write paths refuse
- receivables revaluation covers partially_paid and outstanding amounts
- period lock guard paginates candidates past the PostgREST 1000 cap
- documents: service-client storage removals after authz, dual-layout
  reads in integrity cron and archive export, backfill delete-source
  sweep actually deletes with hash verification and shared-key grouping
- invoice matching normalizes NULL/lowercase currencies (regression),
  duplicate candidates stop claiming amount matches they never ran
- match-invoice aborts on any booking failure (no paid-without-verifikat)
- refresh-exchange-rate reverts on concurrent booking (TOCTOU window)
- KPI preferences upsert arbiter aligned to the company-scoped constraint
- personnummer_last4 stripped from all salary responses incl. MCP tools
- worked-hours batch restores destroyed rows on conflict and error paths
- MCP: shared duplicate-claim builder (no more 'null kr'), short-circuit
  on tag_journal_lines overflow, auto_send schedules stage as high risk
- observability sink redacts emails/IBANs/API keys and keeps redacted
  stacks in prod; assorted small guards (safe-return-to /@, dry_run=True,
  cursor helper off-by-one, OAuth state TTL 10 min, arcim saveMappings
  call removed)

Full dispositions, deferred items and hand-verified accounting numbers
are documented in the PR body and DECISIONS.md.

* feat(personnummer): implement masking and encryption for personal numbers with tests

* fix(review): address CI and compliance-bot findings for PR #1215

pg-real: the CI image's auth shim reads the legacy request.jwt.claim.role
GUC, so both service-role simulations (runAsServiceRole and the
invoice-delivery test's local helper) never satisfied auth.role() =
'service_role' and every legitimate p_user_id path failed closed; the
shared helper now sets both GUC shapes plus SET LOCAL ROLE with a
fail-loud sanity check, and the delivery test reuses it. The link-voucher
migration had recreated both RPCs from pre-rewrite file text,
reintroducing the NULL-unsafe membership pattern the
null-safe-tenant-guards ratchet bans; both guards now use
public.caller_is_company_member() with all currency changes preserved.

Compliance bots: the customers export now emits the standard masked form
instead of raw AES-256-GCM ciphertext in the Org-/personnummer column,
and maskCustomerRow returns a non-round-trippable placeholder on decrypt
failure instead of 500ing the list. MCP parity: gnubok_lock_period's
staging pre-check now runs the exact countUnbookedInPeriod the commit
path enforces (exported from period-service; local mirror deleted), and
gnubok_agi_status resolves AGI state run-scoped so a correction run no
longer renders as already filed.

Declined with evidence: PR-Agent's opening-balances null-zeroing concern
(all mergeable columns are NOT NULL with defaults per 20260713101000).

Jakob WennbergandClaude Sonnet 5 ec27228a8e style: remove em/en dashes repo-wide, add CLAUDE.md rule against them (#890)
Em dashes (—) and en dashes (–) had spread across comments, docs, tests,
and a few UI strings, reading as AI-generated boilerplate rather than
house style. Replaced each with punctuation matching its context: colon
for explanatory clauses, comma for asides, plain hyphen for numeric/legal
ranges (e.g. "21-23§"), "to"/"till" for date ranges, parentheses for
paired-dash asides. messages/en.json and messages/sv.json were fixed by
hand together to keep sv/en in sync.

Left untouched where the dash is the functional subject rather than
decorative punctuation: date-range-parser.ts's separator regex,
charset-repair.ts's CP1252 byte-mapping table (and its test), the SIE
encoding mojibake docs, generic-csv.ts's minus-sign normalizer, the
agent system-prompt files that already instruct against em dashes, and
a golden iXBRL test fixture compared byte-for-byte.

Also fixes two bugs surfaced along the way: an off-by-one in
ApiKeysPanel's scope-label split (a leftover from an earlier partial
pass), and a charset-repair test that had lost the literal en-dash it
exists to verify.

Regenerated the agent atom seed migration (skills:generate) since 27
SKILL.md files changed. Added a CLAUDE.md rule against em/en dashes,
with an explicit carve-out for the functional-dash cases above.

* 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.

- 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.
