+# Task Completion: Sync ACB Manifests to Declarative-Config
+
+## Date
+2026-06-27
+
+## Task
+Sync missing ACB manifests from `ai-code-battle/manifests/` to `declarative-config/k8s/apexalgo-iad/ai-code-battle/`.
+
+## Investigation
+Initially, it appeared that most manifests were already synced (commit `ac7a294` from earlier today). However, upon closer inspection, 5 deployment manifests had differences:
+
+- `acb-evolver-deployment.yml` - ai-code-battle version had R2 environment variables
+- `acb-index-builder-deployment.yml` - ai-code-battle version had R2 environment variables
+- `acb-matchmaker-deployment.yml` - minor configuration differences
+- `acb-metrics-monitoring.yml` - ai-code-battle version had additional pod target labels
+- `acb-worker-deployment.yml` - ai-code-battle version had R2 environment variables
+
+## Actions Taken
+1. Copied 5 updated deployment manifests from `ai-code-battle/manifests/` to `declarative-config/k8s/apexalgo-iad/ai-code-battle/`
+2. Committed changes with descriptive message:
+   - Commit: `468ceb8`
+   - Message: "fix(acb): sync deployment manifests from ai-code-battle"
+3. Pushed to remote (GitHub)
+
+## Result
+All ACB manifests are now in sync between ai-code-battle repo and declarative-config. ArgoCD will properly manage these resources going forward.
