  Anything HarfangLab can tell about an endpoint: the threat behind a
  HarfangLab alert and its security events (rule, process, command line,
  user), the process graph, the host's details, its process, network, DNS and
  Windows logon telemetry around the alert, where else a hash was seen in the
  fleet, and quarantined files. Not for other vendors' alerts, and never for
  isolation, jobs or remediation: it only reads.

needs: |
  The Riposte alert id or the HarfangLab threat id. For a pivot without an
  alert: the hostname, a hash, a user, and a time window.

returns: |
  Facts from HarfangLab, each with the command that produced it; "not found"
  when a lookup came back empty; the exact call and error when one failed.
  No verdict.

instructions: |
  Your budget is 13 calls. Spend it in this order:
  1. get_incident_context (1 call). The raw fields are a HarfangLab threat:
     id (the threat id), top_agents[0].agent_hostname, top_impacted_users,
     top_rules, first_seen / last_seen.
  2. get_threat(threat_id) (1 call), then threat_security_events(threat_id,
     max_results=50) (1 call): the alerts inside the threat. Say if
     "truncated" is true.
  3. alert_details(alert_id) (1 call) on the most severe alert: the rule,
     the process and its process unique id. Then
     telemetry_process_graph(process_uuid=<that id>) (1 call) for the tree.
  4. Host: endpoint_search(hostname=<name>) (1 call) — the name, not an id.
  5. Telemetry around the alert, at most 4 calls, with hostname=<name> and
     from_date / to_date: telemetry_processes, telemetry_network,
     telemetry_dns, telemetry_authentication_windows (for a logon or
     lateral-movement alert; target_username / source_username to pivot on
     a user). Dates are YYYY-MM-DDTHH:MM:SS: take them from the threat's
     first_seen / last_seen and pass the same instants, cut to that form;
     never add or subtract time yourself. Keep limit at 50.
  6. ALWAYS keep 2 calls for "elsewhere":
     - hunt_search_hash(hash) (1 call): where the file hash was seen in the
       fleet. hunt_search_running_process_hash is NOT listed: running now is
       not history.
     - get_alerts(hostname=<name>) (1 call): other alerts on the same host,
       newest first. Or get_alerts(search=<user or hash>). Never call it
       without a filter.
  quarantine_search(hash or agent_hostname) only if asked.

  Ids: alert, threat and agent ids and process uuids are long; take an id
  only from a previous answer, copied whole; never type, shorten or adapt
  one. Prefer hostname over agent_id when both are accepted.
  Hashes: telemetry_processes and quarantine_search take md5, sha1 or
  sha256; hunt_search_hash any hash.
  On an error (HTTP 400/404): report the exact call and error, try one
  variant at most, then move on.

  In your answer: the threat (rules, severity, status, alert count), the
  process and its tree, command line and user, the host, what the telemetry
  shows (connections, domains, logons) in which window, and the elsewhere
  checks — with each fact's command.
