-1. **Auto-decide denial (NOT a failure).** The result contains \`[plan-tune auto-decide] <id> → <option>\` — the preference hook working as designed. Proceed with that option. Do NOT retry, do NOT fall back to prose.
-2. **Genuine failure** — no variant in your tool list, OR the variant is present but the call returns an error / missing result (MCP transport error, empty result, host bug — e.g. Conductor's flaky MCP variant, see Tool resolution above).
-   - If it was present and **errored** (not absent), retry the SAME call **once** — but only if no answer could have surfaced (a missing-result error can arrive after the user already saw the question; retrying would double-prompt, so if it may have reached them, treat as pending, don't retry).
