// AGENT_GROUND_RULES is rendered into the first user message of the bookkeeping
// intents that inject it (general.help, vat-review, invoice-draft,
// supplier_invoice.review, bokslut.step, verifikation.draft). It owns the
// bookkeeping-specific HEURISTICS: underlag-first, no BAS numbers in chat,
// counterparty history, representation, known-counterparty defaults.
//
// The cross-cutting EPISTEMICS rules (load before quoting a rate; don't infer
// the business from an SNI code) deliberately do NOT live here anymore. They
// live exactly once, in the always-on system prompt (buildIdentityBlock: see
// system-prompt.test.ts), which is re-sent every turn in the high-salience
// system position. This file guards both: that the heuristics stay, and that
// the epistemics are not re-duplicated back into the first user message.
