/**
* run-scheduler-cycle.mjs — TORCH Agent Scheduler
*
* Orchestrates one full scheduling cycle for a given cadence (daily|weekly).
* Selects the next eligible agent from the roster, acquires a distributed Nostr
* lock, executes the agent's prompt via a configured handoff command, verifies
* required artifacts and memory evidence, then publishes completion.
*
* This script owns the full lifecycle for a single agent slot per invocation:
* lock acquisition → prompt execution → artifact verification → lock:complete.
* Spawned agents MUST NOT call lock:complete themselves.
*
* Main flow (mirrors src/prompts/scheduler-flow.md numbered MUST steps):
* 1. Parse cadence (daily|weekly), platform, and model from CLI args.
* 2. Load roster from src/prompts/roster.json.
* 3. Read AGENTS.md policy file (best-effort, non-fatal if missing).
* 4. [loop] Read cadence run-state (deferral tracking for the current UTC day).
* 5. [loop] Optional lock health preflight — fail/defer if all relays unhealthy.
* 6. [loop] Run lock:check to build the exclusion set (locked + paused + completed).
* 7. [loop] Apply local time-window guard (24 h daily / 7 d weekly) to exclusion set.
* 8. [loop] Round-robin select next eligible agent from roster minus exclusion set.
* 9. [loop] If no agent eligible → exit (cycle-saturated or all-excluded).
* 10. [loop] Acquire lock with retry. exit 3 → back to step 4; exit 2 → defer or fail.
* 11. [loop] Validate prompt file (readable, correct format).
* 12. [loop] Clear deferral state. Run memory retrieve command (if configured).
* 13. [loop] Run handoff command — hard fail if missing or exits non-zero.
* 14. [loop] Run memory store command (if configured).
* 15. [loop] Verify memory evidence (markers/artifact files).
* 16. [loop] Verify run artifacts via verify-run-artifacts.mjs.
* 17. [loop] Run validation commands (default: npm run lint).
* 18. [loop] Publish lock:complete — hard fail if relay error.
* 19. [loop] Write completed task log and print run summary. Exit 0.
*
* Key invariants:
* - lock:complete is called ONLY after all validation gates pass (step 18 is last gate).
* - Completed task log is written ONLY after lock:complete succeeds.
* - Lock exit code 3 (race lost) causes a loop restart to pick the next agent.
* - Memory mode 'required' turns missing evidence into a hard failure.
