* fix(sandbox): repair the silently-failing nightly sandbox cleanup and lock down its RPCs
The daily cleanup cron has deleted nothing for months: cleanup_sandbox_user
died on the journal-line immutability trigger for every user (the seed posts
vouchers since spring), and cleanup_expired_sandbox_users swallowed each
failure as a WARNING while reporting success. 658 expired sandbox users plus
21 orphaned anonymous users had accumulated in prod auth.users.
- cleanup_sandbox_user sets the sanctioned gnubok.allow_delete flag plus a
new transaction-local gnubok.sandbox_cleanup flag, only after verifying
is_sandbox; write_audit_log, audit_log_immutable (DELETE only, per-row
sandbox re-check), enforce_dimension_registry_guards (DELETE only) and
enforce_pending_operations_no_delete (DELETE only) respect it
- clears salary_runs voucher-link FKs and purges the sandbox company's
audit rows before the auth.users cascade
- cleanup_expired_sandbox_users returns {cleaned, failed, orphans_removed},
additionally sweeps expired anonymous users that never got a
company_settings row, and takes an optional p_limit for bounded batches;
the cron route logs failures at error level and accepts both return shapes
- both RPCs lose their default PUBLIC EXECUTE grant (anon and authenticated
could call them via PostgREST) and are now service_role-only
- validated by replaying the full delete chain against prod inside aborted
transactions (21 users sampled across all seed eras, zero failures) and a
committed staging run; pg-real suite + cron route unit tests added

* fix(sandbox): per-row sandbox re-verification in teardown guards, is_anonymous column guard
Resolution pass for PR #1449 review findings and the pg-real CI failure:
- Swedish accounting review: enforce_dimension_registry_guards and
enforce_pending_operations_no_delete now re-verify per row that
OLD.company_id belongs to a sandbox company (same pattern as
audit_log_immutable) instead of trusting the gnubok.sandbox_cleanup flag
alone. Because that re-check needs company_settings to still exist,
cleanup_sandbox_user deletes pending_operations and dimensions explicitly
before the auth.users cascade.
- pg-real CI: auth.users.is_anonymous does not exist in the CI
supabase/postgres image (or on older self-hosted stacks); the orphan sweep
in cleanup_expired_sandbox_users is now guarded on the column's existence,
and the pg test skips the orphan assertions on such stacks.
Re-validated on staging end-to-end: {cleaned: 5, failed: 0,
orphans_removed: 1}, fresh users and non-sandbox rows untouched.

* fix(sandbox): make company_settings.is_sandbox write-once, prove orphan sweep fails loudly
Round-2 review findings (Swedish accounting review on PR #1449):
- Every teardown bypass trusts company_settings.is_sandbox, and RLS lets an
owner update their own settings row via PostgREST, so a real company that
flipped the flag would become eligible for full deletion by the nightly
cron. New trigger makes the flag write-once (no application path updates
it; a future sandbox-to-real conversion would ship its own migration).
- New pg test pins the reviewer's remaining concern: an anonymous user who
somehow has bookkeeping but no company_settings row is NOT silently
deleted by the orphan sweep; the unbypasseed immutability triggers make
the deletion fail loudly into the summary's failed count.
Validated on staging: flip blocked in both directions, unrelated
company_settings updates unaffected.

* fix(sandbox): guard is_sandbox provenance at INSERT, make orphan sweep exclusions explicit
Round-3 review hardening, approved by Emil:
- is_sandbox = true can now only be created by an anonymous-user JWT (the
sandbox seed's actor), service_role, or a direct database session. A
regular authenticated user could previously insert their settings row
pre-flagged and have the nightly cron destroy their real books, which
BFL 7 kap. forbids even self-inflicted. Claims are read from the
request.jwt.* GUCs directly so the check behaves identically on hosted,
self-hosted, and the CI auth shim.
- The orphan sweep now explicitly excludes anonymous users attached to any
companies or company_members row, instead of relying on downstream
immutability triggers throwing (emergent safety) to protect half-seeded
users.
- pg tests updated accordingly: blocked/allowed provenance paths, and the
half-seeded user is proven unreachable rather than merely failing loudly.
Validated on staging: authed insert blocked, anonymous-claim insert
allowed, half-seeded user untouched, sweep summary failed=0.

* fix(sandbox): all-rows sandbox check, cleared bypass flags, tighter insert guard
CodeRabbit review pass on PR #1449 (its first non-rate-limited run):
- cleanup_sandbox_user now requires EVERY company_settings row of the user
to be sandbox-flagged, not an arbitrary single row: a hypothetical
mixed-company user would otherwise have their real company's rows reached
by the user-scoped deletes.
- Both bypass flags are cleared before the RPC returns, so later work in
the same transaction (the expired loop's next iterations, the orphan
sweep) never runs with them still armed.
- The is_sandbox insert guard now treats ANY PostgREST claims context
(claims json without a role claim included) as guarded, instead of
falling open when the role claim is absent.
- The flag-leak pg test now runs inside an explicit transaction (the old
version could not observe transaction-local GUCs at all), and a new test
covers the mixed sandbox/real user refusal.
Declined: replacing the em dashes inside the two replicated Swedish
exception messages; they are byte-identical copies of the strings already
deployed by migration 20260702084500 and changing them would alter live
user-facing errors out of scope.
Validated on staging: mixed user refused, flags cleared post-teardown,
role-less claims blocked.
