Acceptance Criteria

For a task to be acceptable, it must meet all criteria:

Working around the Nebula RBAC provisioner flake (task-author guide)

If your Horizon DevOps task sets ALLOWED_NAMESPACES to anything beyond the default set (bleater,bleater-env,default), you are exposed to a base-image bug that drops 30–80% of rollouts with no useful logs. This guide gives you a drop-in setup.sh patch to self-heal while the upstream fix lands.

Severity: silent failure. The agent runs as system:serviceaccount:default:ubuntu-user and gets Forbidden on every namespaced operation in the missed namespaces. Looks like a flailing agent;

Review: configmap-projection-order-race v2

Verdict: APPROVE

v2 passes all acceptance criteria. solution.sh scores 1.0 locally, docker mean is 0.44 (<0.50 threshold), teapot mean is 0.27 (≤0.85 threshold), and failures are genuine — agents get tripped up on the five-fault ordering puzzle, not on grader defects or setup flakes. Four non-blocking recommendations below, but nothing that should block acceptance.

Review: projected-volume-timeout-conflict v20

Verdict: APPROVE

What's Working

The task concept is strong and the v20 execution delivers on it. Projected-volume source ordering maps to real incidents, the multi-key ConfigMap conflict creates genuine reasoning difficulty, and the GitOps reconciliation requirement (~28 handoff files across 5 directories in JSON, env, YAML, INI, and TSV formats) adds
