# contract-run.sh — Deterministic contract execution from machine scheduler
|

#
|

# Takes a contract name, resolves its script, runs it with timeout,
|

# logs output to /var/log/contract-runs/, and alerts on failure.
|

#
|
||||
# Usage: bash scripts/contract-run.sh <contract-name>
|
||||
#
|
||||
# Contract names map to scripts as follows:
|
||||
# infrastructure-monitoring -> scripts/infra-monitoring.sh
|
||||
# proxmox-monitor -> scripts/proxmox-monitor.sh
|
||||
# zulip-health -> scripts/zulip-monitor.sh
|
||||
# agent-health-check -> scripts/agent-health-check.py
|
||||
# litellm-health -> scripts/litellm-health-check.py
|
||||
# disk-gc-threat-response -> (Python script, needs investigation)
|
||||
# pm2-self-heal -> scripts/pm2-self-heal.sh
|
||||
#
|
||||
# Exit codes:
|
||||
# 0 = contract passed
|
||||
# 1 = contract failed (alert sent)
|

# 2 = probe failed (script missing, timeout, etc.)
