Stripe sends zero-decimal currencies (JPY/KRW/VND/...) already in the
major unit; the unconditional /100 recorded a JPY dues charge 100x
understated in the ledger + receipt. minorToMajor is now currency-aware
(shared ZERO_DECIMAL_CURRENCIES/isZeroDecimalCurrency in
notifications-logic); formatMoney renders no fractional part for those.
Never fires for USD; closes silent ledger corruption for such tenants.
Tests added; suite 526+.
Independent audit verdict was NOT SAFE; all findings fixed:
- dispatcher Idempotency-Key is now per-attempt (${id}:${attempts}),
not row id alone, so a transient-failure response cached by Resend
cannot permanently suppress every retry and silently lose an email.
- enqueueDues is fully try/catch wrapped so a notifications-table or
render failure can never throw into / wedge the Stripe money path.
- dues_lapsed dedupe falls back to the subscription id when periodEnd
is null (canceled/deleted subs), so future lapses no longer collapse
to one key and get suppressed. New test; suite 499.
- documented the dispatcher's once/min concurrency assumption.
Migration 041 + schema.sql section 26: notifications outbox (service-only
writer, admin/board/treasurer SELECT, member self-view via validated
service action like member_billing; (space_id, dedupe_key) unique makes
the webhook enqueue idempotent). lib/notifications-logic.ts is pure:
deterministic dedupe keys, dues email rendering (HTML-escaped, brand-
neutral), terminal-attempt rule. 13 tests. Inert until P2c wires it.
