Accounting

Bulk-create monthly + FY accounting periods for a range of fiscal years

Required API key scope: accounting:write

Backfills missing monthly + fiscal-year accounting periods for the entity across a fiscal-year range. Reuses the canonical seedAccountingPeriodsForFY helper (the same code the monthly cron + entity-seed call). Idempotent: re-running inserts zero rows for years already covered.

Why this endpoint exists. The monthly cron create_monthly_accounting_periods only creates current + next FY; entity-seed only creates the current FY. Neither covers historical periods needed when migrating data from years past (e.g. WSS Versa migration loads JEs for 2020..cutover_year, which all need period_id resolved correctly via resolvePeriodForDate). Without this, historical JEs land with period_id = NULL and period-grouped reports under-count.

Returns per-year inserted counts so the caller can verify the desired range is fully covered.

Safety cap: range cannot span more than 30 fiscal years per call.

Added 2026-05-28 (MIGRATION-MAPPING-NATIVE wave 5a).
