The vendor-neutral accounting pack — two cross-vendor money-ops recipes that run against whatever accounting platform you enroll (QuickBooks Online or Xero, or any registered accounting vendor). Every read uses a `core.acct.<entity>.search` kernel op (invoice / payment / customer), so the pack carries no bundled catalog: each op resolves at run against the catalog the bound connection's vendor declares, and projects the canonical accounting fields (balance / due_date / customer_id / email) — never raw vendor records. This is the showcase for the `core.acct.*` canonical convention; the catalog + the money-write surface (invoice/payment/refund creates, always approval-gated) live in the per-vendor capability packs (`accounting-quickbooks` / `accounting-xero`), which you also install to bind a connection. Canonical accounting op-steps are read-only — `overdue-invoice-chase` only sends a reminder email through the gated mail-send kernel ingredient, never moving money. Installs dormant until you pick an enrolled accounting connection for each recipe's `acct` variable (Settings -> the recipe), then runs against the D-165 gateway (operation-level risk / grant / approval + per-call audit).
