// Unit tests for the identity-file tool dispatch surface:
//   - `edit_soul` (per-agent SOUL.md, auto-approved)
//   - `edit_user_profile` (instance USER.md, auto-approved)
//
// Mirrors memory-dispatch.test.ts's seeding pattern (active agent +
// task) and exercises the edit path end-to-end through dispatchToolCall.
// Both tools auto-approve a clean body and route an injection-flagged
// body through the .proposed gate, so these tests pin:
//   - a clean body lands at the approved file (effective next turn)
//   - an injection-flagged body lands at .proposed and stays out of the
//     prompt until the operator approves it
//   - the audit row is emitted with actor: "agent"
//   - the action="append" path layers on the existing approved body
