# istio-validation-debugger ## Execution Mode — FULLY AUTONOMOUS **NEVER ask the user for confirmation.** Fetch logs, interpret, propose and apply fixes immediately. The only user-facing handoff in the loop is triggering rollouts (owned by `istio-iteration-loop`). This skill never has user-facing handoffs. ## Goal Turn an Oracle or No-Op failure into a specific root cause with a specific fix, from log evidence — not guesswork. If you cannot map the pattern to a row below with confidence, investigate manually from the `output.txt` setup log + a re-read of setup.sh/solution.sh/grader.py before changing any file. (The live red-team / `horizon-agentic-reviewer` is DISABLED for this task — do not invoke it.) ## Trigger Oracle ≠ `1.0/passed`; No-Op `score > 0` (false positive); grader exception; `feedback: null` (setup crash); or you are about to edit setup/solution/grader after a validation failure. NOT for rollout failures — use `istio-score-tuner`. ## Task Identity | Field | Value | |---|---| | **Task UUID** | `<TASK_ID>` | | **Slug / path** | `variation-istio-split-brain` / `tasks/variation-istio-split-brain/` | | **Subscores** | `routing_restored` (0.5) + `mesh_governance` (0.5), both binary | | **Venv** | `source /Users/mac/Documents/tasks/horizon_env/bin/activate` | | **Grader version** | **v2** — includes the admission webhook, the bleater-env drift, the HPA/finalizer protections, and the two `/etc/bleater` decorrelating gates | **v2 root-only files the grader read
