Red-team money findings:
- createCreditNote caps the CN to the invoice's remaining creditable value
(invoice payable − already-credited by non-cancelled CNs), read+insert in
one txn. Blocks a CN exceeding its invoice / unlimited CNs flipping it 'paid'.
- nextDocNo allocates via one atomic UPDATE ... RETURNING (row lock) instead of
read-then-bump — no duplicate/burned numbers under concurrent issue (Postgres).
- markStatus rejects accepted/lost on non-QUOTATION docs — an issued invoice can
no longer be hidden from overdue chasing via a quote-only transition.
- computeBill bounds qty magnitude (keeps fractional for weighed Store goods);
HQ buildLines additionally requires whole-unit integer qty (SMS/module seats).
- recordPayment rejects TDS greater than the cash received — no fabricated-TDS
'settlement' with no money.
money-guards test locks all four. Suite money paths green.

P1: every repo, route, scheduler path and test now speaks one async DB
interface (all/get/run/exec/transaction). better-sqlite3 stays underneath
for dev/tests via SqliteDb (statement cache, manual BEGIN/SAVEPOINT
nesting); openDb stays sync so fixtures remain one-liners. Zero behavior
change: 346/346 tests, typecheck clean.
P2: migrations-pg.ts — numbered Postgres migration set (001-init: bigint
paise, integer flags, TEXT ISO dates, TEXT JSON; reminder CHECK born in
final widened form) + schema_migrations runner.
P3: db-pg.ts — pg Pool behind the same interface: ?->$n rewrite outside
string literals, transactions pinned to one pooled client via
AsyncLocalStorage with savepoint nesting, int8/numeric parsed to JS
numbers so paise math is identical on both engines.
Also: reminder upsert INSERT OR IGNORE -> ON CONFLICT DO NOTHING
(portable, same changes-count semantics).
