mega-plant/scripts/setup-invoice-edits-collection.mjs

// Create the `purchase_invoices` PocketBase collection.
//
// Audit log of edits to a supplier invoice (amount / date / number). Append-only: the app
// never updates or deletes a row. The invoice and PO numbers are copied as TEXT so the log
// still reads correctly if the invoice itself is later deleted.
//
// Idempotent: safe to re-run.
//
// Usage: node scripts/setup-invoice-edits-collection.mjs
