## 🔐 1. GLOBAL LLM BUDGET ENFORCEMENT (CRITICAL)

### 1.1 Turn-Level Budget
- **STATUS**: ✅ **IMPLEMENTED**
- **EVIDENCE**: [`context.py:27-28`](file:///d:/honeypot/sentinel-scam-honeypo/app/core/context.py#L27-L28) (`llm_call_count`, `budget_exceeded`), [`llm_client.py:1458-1467`](file:///d:/honeypot/sentinel-scam-honeypo/app/core/llm_client.py#L1458-L1467) (`MAX_PER_TURN = 4`).
- **DETAILS**: 
  - `TurnContext` contains `llm_call_count: int` and `budget_exceeded: bool`.
  - Counter is incremented **before** every LLM call.
  - Hard-stop at `MAX_PER_TURN = 4` via `BudgetExceeded` exception.

### 1.2 Session-Level Budget
- **STATUS**: ⚠️ **PARTIAL** (Storage Implemented, Enforcement Pending)
- **EVIDENCE**: [`memory.py:89`](file:///d:/honeypot/sentinel-scam-honeypo/app/core/memory.py#L89) (`session_llm_calls: 0`).
- **DETAILS**: 
  - `session_llm_calls` field added to `ConversationMemory`.
  - **Pending**: Session budget cap enforcement in `LLMClient` (requires orchestrator to pass session object with context).
- **ACTION REQUIRED**: Integrate session consumption tracking in `orchestrator.py` to update `session_llm_calls` on each turn end.

### 1.3 Single Choke Point Rule
- **STATUS**: ✅ **IMPLEMENTED**
- **EVIDENCE**: All agents (`ScamDetector`, `IntelligenceExtractor`, `PersonaEngine`) pass `TurnContext` to `llm_client.generate*()` methods.
- **DETAILS**: Budget enforcement is centralized in `LLMClient.generate_res`.

---

## 🛡️ 2. SAFETY GUARD CLAMPING (LOOP PREVENTION)

### 2.1 One-Way Safety Decision
- **STATUS**: ✅ **IMPLEMENTED**
- **EVIDENCE**: [`orchestrator.py:161-172`](file:///d:/honeypot/sentinel-scam-honeypo/app/agents/orchestrator.py#L161-L172).
- **DETAILS**: 
  - `ctx.finalized = True` and `ctx.reply_mode = "HONEYPOT_ONLY"` are set on safety block.
  - Immediate return prevents any downstream agent execution.

### 2.2 Post-Safety Behavior
- **STATUS**: ✅ **IMPLEMENTED**
- **DETAILS**: After a safety block, only static `HONEYPOT_ONLY` response is allowed. No retries or cascades.

---

## 🎭 3. PERSONA CONSISTENCY LOCK (HONEYPOT REALISM)

### 3.1 Persona Locking
- **STATUS**: ✅ **IMPLEMENTED**
- **EVIDENCE**: [`orchestrator.py:332-342`](file:///d:/honeypot/sentinel-scam-honeypo/app/agents/orchestrator.py#L332-L342) (`HARD PERSONA LOCK`).
- **DETAILS**: 
  - `persona_key` is stored in session memory after Turn 1.
  - `persona_locked: bool` logic is present via conditional check on `existing_persona_key`.
  - Persona is never re-selected after initial assignment.

### 3.2 Trait Mutation Rules
- **STATUS**: ✅ **IMPLEMENTED**
- **EVIDENCE**: [`persona_engine.py:382-402`](file:///d:/honeypot/sentinel-scam-honeypo/app/agents/persona_engine.py#L382-L402) (`mutate_traits`).
- **DETAILS**: 
  - Trait intensities (e.g., `scared`, `trusting`) are allowed to mutate.
  - Persona class (e.g., `elderly_excited`) switching is explicitly blocked.

## 🧠 4. SCAM DETECTION FAST-PATH CONTROL

### 4.1 Sticky Detection
- **STATUS**: ✅ **IMPLEMENTED**
- **EVIDENCE**: [`orchestrator.py:249-257`](file:///d:/honeypot/sentinel-scam-honeypo/app/agents/orchestrator.py#L249-L257).
- **DETAILS**: 
  - Once `scam_type` is set in session memory, `ScamDetector` is bypassed.
  - Cached detection is reused without LLM calls.

### 4.2 Heuristic Priority
- **STATUS**: ✅ **IMPLEMENTED**
- **EVIDENCE**: [`scam_detector.py:238`](file:///d:/honeypot/sentinel-scam-honeypo/app/agents/scam_detector.py#L238).
- **DETAILS**: 
  - Regex confidence threshold is `0.85` on Turn 1, `0.70` on later turns.
  - LLM reasoning is skipped when heuristic confidence is high.

---

## 🧬 5. INTELLIGENCE EXTRACTION THROTTLING

### 5.1 Turn-Based Throttling
- **STATUS**: ✅ **IMPLEMENTED**
- **EVIDENCE**: [`intelligence_extractor.py:57-69`](file:///d:/honeypot/sentinel-scam-honeypo/app/agents/intelligence_extractor.py#L57-L69).
- **DETAILS**: 
  - LLM extraction is limited to Turn 1 and every 3rd turn thereafter.
  - Regex extraction is always allowed.

### 5.2 High-Priority Override
- **STATUS**: ✅ **IMPLEMENTED**
- **DETAILS**: 
  - New UPI, bank account, or phone number detection via regex forces an LLM extraction call.
  - Confidence jump > 0.2 also triggers extraction.

---

## ⚙️ 6. MODEL FALLBACK DEPTH CONTROL

### 6.1 Cascade Limit
- **STATUS**: ✅ **IMPLEMENTED**
- **EVIDENCE**: [`llm_client.py:197-198`](file:///d:/honeypot/sentinel-scam-honeypo/app/core/llm_client.py#L197-L198).
- **DETAILS**: 
  - `max_retries = 2` (Hard limit).
  - After 2 failures, system goes LOCAL ONLY.

### 6.2 Key Rotation Rules
- **STATUS**: ✅ **IMPLEMENTED**
- **EVIDENCE**: [`llm_client.py:212-215`](file:///d:/honeypot/sentinel-scam-honeypo/app/core/llm_client.py#L212-L215).
- **DETAILS**: 
  - Keys are rotated only on quota errors (429, `rate_limit`, `insufficient_quota`).
  - Keys are NOT rotated on 400 errors, safety blocks, or schema mismatch.

---

## 🧪 7. TEST & VERIFICATION COVERAGE

### 7.1 Budget Tests
- **STATUS**: ⚠️ **PARTIAL**
- **DETAILS**: 
  - Manual verification script exists: [`scripts/verify_production_hardening.py`](file:///d:/honeypot/sentinel-scam-honeypo/scripts/verify_production_hardening.py).
  - **Pending**: Automated CI tests for max LLM calls per turn and session.

### 7.2 Persona Stability Test
- **STATUS**: ✅ **IMPLEMENTED**
- **EVIDENCE**: Audit script confirms persona never changes across multi-turn simulations.

### 7.3 Failure Simulation
- **STATUS**: ⚠️ **PARTIAL**
- **DETAILS**: 
  - No automated tests for 429 exhaustion, safety block, or schema failure → local fallback.
- **ACTION REQUIRED**: Implement `tests/test_audit_failure_modes.py`.
