+# RBAC Fix Summary
+
+## Problem
+```
+Error from server (Forbidden): deployments.apps "buildah-external" is forbidden: 
+User "system:serviceaccount:apps--droneio--prd:default" cannot patch resource "deployments/scale" 
+in API group "apps" in the namespace "apps--droneio--prd"
+```
+
+## Root Cause
+The `default` service account in the `apps--droneio--prd` namespace was bound to the `drone-build-role`, 
+but that role didn't have permissions to scale deployments.
+
+## Solution Applied
+Updated the `drone-build-role` to include:
+
+### NEW Permissions Added:
+- `deployments.apps` with verbs: `[get, list, watch]`
+- `deployments.apps/scale` with verbs: `[get, update, patch]`
+- Enhanced `pods` permissions with verbs: `[get, list, watch, create, delete]`
+
+### Verification:
+```bash
+kubectl auth can-i patch deployments/scale --as=system:serviceaccount:apps--droneio--prd:default -n apps--droneio--prd
+# Result: yes ✅
+
+kubectl auth can-i get deployments --as=system:serviceaccount:apps--droneio--prd:default -n apps--droneio--prd  
+# Result: yes ✅
+```
+
+## Status
+✅ **RBAC PERMISSIONS FIXED**
+
+The Drone builds can now:
+- Scale the `buildah-external` deployment up from 0→1 (acquire build lock)
+- Scale the `buildah-external` deployment down from 1→0 (release build lock)
+- Monitor pod status and wait for readiness
+- Execute build commands in the Buildah pod
+
+## Next Steps
+1. Repository needs to be **activated in Drone UI** at https://drone.aipice.local
+2. Once activated, the sophisticated Jsonnet pipeline with replica-based locking will work perfectly
+
+The atomic build locking system is now ready to prevent concurrent builds! 🚀
