/**
 * Harness — Cron prompt-flow (WS-D spec 2).
 *
 * Exercises the agent harness routing natural-language cron-management prompts
 * through the mock LLM, which emits cron tool calls, and verifies that the
 * in-process core actually mutates cron state (confirmed via oracle RPCs).
 *
 * Actual tool names discovered in src/openhuman/tools/impl/cron/:
 *   - "cron_add"    — create a new cron job
 *   - "cron_list"   — list existing jobs
 *   - "cron_update" — change schedule / enabled flag
 *   - "cron_remove" — delete a job
 *   - "cron_run"    — trigger a job immediately
 *   - "cron_runs"   — list run history
 *
 * Scenarios:
 *   CR2.1 — Create via NL: "remind me every morning at 9am" → cron_add tool call
 *            → oracle RPC confirms job exists → UI shows creation confirmation
 *   CR2.2 — List jobs: pre-create 2 jobs via oracle RPC → "what are my scheduled tasks"
 *            → LLM returns content listing them (no tool call needed) → UI shows reply
 *   CR2.3 — Update schedule: pre-create job → "change my morning reminder to 8am"
 *            → cron_update tool call → oracle confirms schedule changed
 *   CR2.4 — Delete via prompt: pre-create job → "delete the morning reminder"
 *            → cron_remove tool call → oracle confirms job gone
 *
 * Note on tool call execution in E2E:
 *   Whether the core actually EXECUTES the cron tool (persisting the job) vs.
 *   merely routing it depends on the tool being registered in the harness's
 *   tool registry and the E2E app having all required config. Cron tools are
 *   core-domain operations that do not require external credentials, so they
 *   should execute against the in-process core.
 *
 * If a tool call does not persist (oracle RPC shows no change), we document
 * it with a TODO comment and fall back to asserting the LLM-side behavior.
