# Argo WorkflowTemplate for deploying evolved bots
# Sync to: declarative-config/k8s/apexalgo-iad/argo-workflows/
#
# Triggered by the evolver when a candidate is promoted.
# The promoter commits bot source to bots/evolved/<bot_name>/ before triggering.
#
# This workflow:
# 1. Clones the ai-code-battle repo (bot source already committed)
# 2. Generates Dockerfile for the language
# 3. Builds container image with Kaniko
# 4. Pushes to Forgejo registry
# 5. Creates K8s Secret, Deployment, Service manifests
# 6. Commits manifests to declarative-config repo (ArgoCD syncs them)
