* fix(db): enforce balance check on directly inserted posted journal entries

check_balance_on_post only fires on the draft-to-posted UPDATE transition,
so any code path that INSERTs a row with status 'posted' directly skipped
balance validation entirely. The invariant sum(debit) = sum(credit) on
every posted entry was DB-enforced only for the engine's commit lifecycle.

Add check_balance_on_posted_insert, a deferred constraint trigger on
AFTER INSERT WHEN (NEW.status = 'posted') reusing the existing
check_journal_entry_balance() function, which already handles the
journal_entries INSERT context via NEW.id/NEW.status. Deferred semantics
let an atomic transaction insert header and lines together; zero-line and
unbalanced posted inserts are rejected at constraint evaluation. All
existing checks stay intact; this only adds coverage.

The one first-party posted-INSERT path outside an RPC, the sandbox seed,
now books through the bookkeeping engine (createJournalEntry) instead of
raw inserts. SIE import already inserts header and lines in a single
transaction via its structured RPC and passes unchanged.

pg tests cover the new path (zero-line rejected, unbalanced rejected at
SET CONSTRAINTS IMMEDIATE, balanced same-transaction insert accepted) and
existing posted-entry fixtures move to a transactional
insertPostedJournalEntry helper so they stay valid setup.

Fixes #327

* fix(tests): insert list-filters pg fixtures in one transaction

The list-filters suite (landed via a sibling merge) inserted posted
headers with getPool().query, where each query autocommits: the deferred
check_balance_on_posted_insert constraint fired at the header's own
commit with zero lines and correctly rejected the fixture. Header and
balanced lines now share one BEGIN/COMMIT so the constraint evaluates
the complete entry, mirroring the insertPostedJournalEntry helper.

* fix(seed): insert journal headers as drafts, post after lines land

check_balance_on_posted_insert (renamed to apply-time version
20260806130000) rejects a posted header whose transaction has no lines.
PostgREST autocommits each request, so every seed path that inserted
posted headers first would die with "has zero total": the sandbox seed
(ledger history, invoice vouchers, salary vouchers), seed-demo-account
and seed-export-data. All now insert draft headers, insert lines, then
flip to posted so check_balance_on_post validates the finished
verifikat. The sandbox seed keeps its documented no-events design.

* fix(db): preserve a preset committed_at on draft-to-posted transition

set_committed_at() stamped now() unconditionally, so the seed flows that
post backdated drafts lost their historical booking timestamps and every
demo verifikat read as booked today (CodeRabbit finding on PR 1439).
Stamp only when committed_at is NULL: the engine path (drafts carry no
committed_at) behaves exactly as before and a posted entry still always
has a committed_at; an explicitly supplied value now survives posting.

* fix(db): preserve preset committed_at only for trusted roles

The IS NULL guard alone (20260806150000, never shipped; replaced by
20260806160000) let any RLS-permitted member backdate committed_at
through PostgREST by presetting it on a draft and posting, which the
Swedish accounting review flagged: committed_at is what the BFL 5 kap
timeliness checks and behandlingshistorik treat as the genuine
transition time. Preset values now survive posting only for
service_role/postgres/supabase_admin; authenticated and anon writers
always get the now() stamp. Consequence: the sandbox seed (runs as the
requesting user) gets committed_at = posting time, accepted and
documented in the route; the demo scripts run as service_role and keep
their backdated history. pg tests cover all four paths, with the upper
timestamp bound CodeRabbit asked for.

* fix(db): restore superseded migration so the preview tracker stays consistent

The preview branch had already applied 20260806150000 when the previous
commit deleted the file, orphaning the preview's migration tracker
("Remote migration versions not found in local migrations directory").
Restored with a header explaining it is superseded in the same deploy by
20260806160000, so the unguarded semantics are never live on their own.

* fix(db): decide committed_at trust by JWT claims, not current_user

The Swedish review found the current_user guard bypassable:
commit_journal_entry is SECURITY DEFINER and granted to authenticated,
so inside it current_user is the function owner and a member could
preset a backdated committed_at on a direct-inserted draft and launder
it through the RPC. The guard now reads the JWT claims role (same
primitive as the RPC's own tenant guard): preset values survive only
for service_role or claim-less backend connections; authenticated and
anon callers are always stamped now(), on both the direct UPDATE and
the RPC path (new pg test). Both migration files now carry the
identical final body so no unguarded intermediate exists as a
standalone applyable unit. Behandlingshistorik logging of trusted
overrides is follow-up #1444.

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.

Jakob WennbergandClaude Opus 4.8 358c25094d fix(security): tenant guard on the GL-line read RPCs (#625)
* fix(security): tenant guard on the GL-line read RPCs (PR #624 follow-up)

get_unlinked_gl_lines and get_account_gl_lines_for_matching are SECURITY DEFINER
and EXECUTE-able by anon/authenticated, so any authenticated (or anonymous)
caller could invoke them directly over /rest/v1/rpc with another company's id and
read its general-ledger lines — a cross-tenant read that bypasses the API routes'
requireCompanyId() guard. Confirmed against the DB: anon and authenticated both
hold EXECUTE, and SECURITY DEFINER sidesteps RLS.

Add an in-function guard constraining anon/authenticated callers to their own
companies (the same boundary user_company_ids()/RLS enforces). Trusted callers
are untouched — service_role (the enable-banking reconciliation cron) and direct
/ superuser access (migrations, the pg-real harness) are not anon/authenticated,
so the predicate is a no-op and behaviour is unchanged. A foreign company id now
yields zero rows, not data.

Scope: hardens the two READ RPCs that expose ledger data. The remaining
company-scoped SECURITY DEFINER RPCs are writes / sequence generators with their
own internal authorization; a broader audit of that set is tracked separately.

pg-real coverage: a company-B member probing company A gets zero rows from both
RPCs, while a company-A member and direct/superuser access still see the data.

* fix(security): revoke EXECUTE from PUBLIC/anon on the GL-line read RPCs

Defense-in-depth follow-up to the tenant guard. The guard already returns zero
rows to an anon/authenticated caller probing another company; this additionally
strips the EXECUTE privilege so an unauthenticated (anon) caller cannot invoke
the financial-ledger RPCs at all. Supabase grants EXECUTE to PUBLIC as well as to
anon, and anon is a member of PUBLIC — revoking only anon is insufficient, so
revoke both, then keep the two legitimate callers: authenticated (the API routes
call via the user's session; the in-function guard scopes them to their own
companies) and service_role (the enable-banking reconciliation cron).

Verified on the DB: anon EXECUTE = false, authenticated/service_role = true.
Adds an anon-role pg test asserting the call is rejected at the privilege layer.

* fix(security): read JWT role from claims object in the GL-line RPC guard

The 20260611120000 guard used auth.role() to detect the caller's role, but
auth.role() reads the individual request.jwt.claim.role GUC first and only some
installs fall back to the claims object. PostgREST sets the claims OBJECT (the
individual claim.* GUCs are deprecated), and the pg-real harness sets
request.jwt.claims (+ claim.sub for auth.uid()) but NOT claim.role — so on an
auth.role() without the object fallback it returns NULL and the guard's
NOT IN ('anon','authenticated') branch was TRUE, skipping the membership check.
A pg-real test caught it: an authenticated non-member could still read another
company's GL lines (the guard failed open in that environment).

Read the role straight from request.jwt.claims (exactly what auth.role() itself
falls back to), so the guard enforces in every environment regardless of which
JWT-claim GUCs are populated. Verified on the DB: an authenticated non-member
evaluates both guard branches false → row excluded.
