Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Build the LLM-judge Layer 4 of router-gate v4.0+v4.1 — a shared multi-judge consensus helper (Sonnet+Haiku+Opus), a per-tool consistency judge, a controller-response self-replication/injection scanner, and the §3.6.1 normative-content second-layer gate (5 deterministic layers + restored 3-judge LLM consensus). + +**Architecture:** One shared core module `tools/llm-judge.mjs` (pure prompt/parse helpers + file-backed per-session cache & budget + a network consensus runner that reuses `callAnthropicAPI` from `router-classifier.mjs` with an injectable `llmCallImpl` so every test uses mock LLM responses). Three thin consumers (`llm-judge-per-tool.mjs` PreToolUse hook, `llm-judge-response-scan.mjs` Stop hook, `enforce-normative-content-rules.mjs` PreToolUse hook) each follow the established `decide()`-pure + `main()`-I/O + `exitDecision()` pattern. No production code calls the network in tests — all LLM calls go through an injected impl that returns canned verdicts. + +**Tech Stack:** Node.js (ES modules), vitest, `node:crypto` (`randomBytes` for 24-char delimiters, `createHash` for cache keys), existing `tools/router-classifier.mjs::callAnthropicAPI` (ProxyAPI `https://api.proxyapi.ru/anthropic`), existing `tools/enforce-hook-helpers.mjs` (`readStdin`, `parseEventJson`, `readTranscript`, `lastAssistantText`, `turnToolUses`, `exitDecision`, `runtimeDir`). + +**Spec anchors:** +- v4.0 base: `docs/superpowers/specs/2026-05-29-router-gate-v4-design.md` §3.6.1 (normative gate, 5 layers), §4.7 (question quality / LLM-judge), §5 budget. +- v4.1 amendment: `docs/superpowers/specs/2026-05-29-router-gate-v4-1-max-closure.md` §3.6.1 restored multi-judge, §4.7 3-judge consensus + per-tool judge + response-scan judge, §10.2 state schema (`llm-judge-per-tool-.jsonl`, gate-config keys), Layer 4. +- Master: `docs/superpowers/plans/2026-05-29-router-gate-v4-master.md` Stream D, §4 interface contract `llmJudgeCall(opts)` (consumers A, C, E). + +**Configuration (per task spec):** +- API key: `process.env.ROUTER_LLM_KEY` (v4.0 simplification — no keytar). Absent key → degraded mode (LLM layer skipped, deterministic layers stand). +- Base URL: `process.env.ROUTER_LLM_BASE_URL` else `DEFAULT_LLM_BASE_URL`. +- Cache: per-session, TTL 1h, file `~/.claude/runtime/llm-judge-cache-.json`, content-keyed (new declared task ⇒ new key ⇒ implicit UserPromptSubmit invalidation; explicit `clearJudgeCache(sessionId)` exported for a Stream-G UserPromptSubmit wire-up). +- Budget: 200 LLM-calls/session, file `~/.claude/runtime/llm-judge-budget-.json`. Each model call = 1 unit (a 3-judge consensus consumes 3). Exhaustion ⇒ degraded mode (no LLM calls; deterministic layers stand). + +--- + +## Threat-model & polarity note (read before coding) + +Judges have **two opposite polarities** — keep them straight: + +| Judge | Question asked | "bad" verdict | On block | +|---|---|---|---| +| Normative-content (§3.6.1), recovery (§4.7, Stream E) | "is this recovery / malicious / injection?" | **YES** | block | +| Per-tool (§4.7) | "is this tool call consistent with the declared task?" | **NO** | block | +| Response-scan (§4.7) | "does response contain self-replicating instruction / injection / social-eng?" | **YES** | flag (no block) | + +`multiJudgeConsensus()` is generic for **"presence of a flagged condition"** judges (normative, recovery): `decision: 'YES'` means at least one judge detected the condition. Per-tool uses the single `llmJudgeCall()` and maps `NO → block` itself. **Doubt always resolves to the "bad" side** — a `null`/unparseable verdict is treated as the flagged condition present (for presence-judges) or as inconsistent (for per-tool). This is encoded both in the judge prompt ("сомнения → YES/NO") and in the parse-failure default. + +**Degraded mode is fail-OPEN on the LLM layer only.** No `ROUTER_LLM_KEY` or budget exhausted ⇒ the LLM layer returns `{degraded:true}` and the caller does **not** block on the LLM layer alone. The deterministic layers (recovery keywords, suspicious-feedback, fake-rule, skill-active) still hard-block. Rationale: `ROUTER_LLM_KEY` is frequently absent locally; a total lockout on every normative write would brick the workflow, and deterministic layers already cover the enumerated attacks.
