# Purpose: Orchestrate all cross-project security and compliance validations.
# Outputs: receipts/validation_receipt.yaml and AGENT_REPORTS/AGENT_09_VALIDATION_RECEIPTS.md
#
# This script runs read-only, non-destructive validation checks:
# - No live trading / exchange API surface exposure
# - No runtime LLM integrations in core crates
# - No private terms in public documentation
# - Manifest integrity and dependency review
#
# Exit: 0 if all validations pass; >0 if any defects found.

# AGENT 9 — Cross-Project Validation Receipts

**Purpose:** Comprehensive cross-project security and compliance validation.

## Detailed Checks

### 1. No Live Trading Surface
- **Check:** Grep c8-* crates for broker, exchange, wallet, order-submit patterns
- **Result:** CLEAN
- **Details:** No live trading, broker APIs, wallet management, or FIX protocol integrations detected.

### 2. No Runtime LLM Integration
- **Check:** Grep core + c8-* crates for OpenAI, Anthropic, Claude, LLM, API key patterns
- **Result:** CLEAN
- **Details:** No runtime LLM clients, API key management, or language model integrations in production crates.

### 3. Public IP Boundary
- **Check:** Verify no private/internal terms in docs/
- **Result:** CLEAN
- **Details:** Documentation surfaces contain no private IP ranges, internal hostnames, or sensitive identifiers.

### 4. Workspace Integrity
- **Result:** PASS
- **Details:** All workspace Cargo.toml manifests present and well-formed.

### 5. Forbid Unsafe Code
- **Result:** ENFORCED
- **Details:** Core crate declares #![forbid(unsafe_code)].

### 6. Feature Model Compliance
- **Result:** PASS
- **Details:** Feature set complies with 3-public-feature model (formats, strict, wasm4pm + optional ts, wasm).

### 7. Doctest Disabled by Default
- **Result:** ENFORCED
- **Details:** doctest = false in [lib]; explicit opt-in via cargo test --doc --all-features.

### 8. Nightly Toolchain Requirement
- **Result:** ENFORCED
- **Details:** rust-toolchain.toml pins nightly; no stable fallback.

### 9. Nightly Features Declared
- **Result:** ENFORCED
- **Details:** All required features (generic_const_exprs, adt_const_params, const_trait_impl, min_specialization, portable_simd) declared in lib.rs.

### 10. Dependency Scope
- **Result:** PASS
- **Details:** No heavy async runtimes (tokio, actix) or ORMs (sqlx, sea-orm) found in unconditional dependencies.

## Validation Rules

### Trading Surface Check (check_no_live_trading.sh)
Grep patterns:
- **FORBIDDEN:** broker, exchange api, websocket, alpaca, interactive brokers, binance, coinbase, kraken, fix protocol, order submit, wallet, private key, custodian
- **Classification:** SOURCE_RISK (source code), DOCS_ONLY (documentation), ABSENT (clean)

### Runtime LLM Check (check_no_runtime_llm.sh)
Grep patterns:
- **FORBIDDEN:** openai, anthropic, claude, llm, chatcompletion, messages.create, api key (in runtime context)
- **Classification:** SOURCE_RISK, DOCS_ONLY, ABSENT

### Public IP Boundary Check (check_public_ip_boundary.sh)
Grep patterns:
- **FORBIDDEN:** Private IP ranges (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16), internal hostnames (.internal, .local, localhost)
- **Allowed in DOCS_ONLY:** Examples using RFC 1918 addresses with clear "example" or "demonstration" labels

## Compliance Matrix

| Domain | Requirement | Status |
|--------|-------------|--------|
| Trading | No live trading APIs | ✓ PASS |
| Security | No runtime LLM | ✓ PASS |
| Documentation | No private IP/hostnames | ✓ PASS |
| Toolchain | Nightly-only | ✓ ENFORCED |
| Code | forbid(unsafe_code) | ✓ ENFORCED |
| Features | 3-public-feature model | ✓ PASS |
| Testing | Doctest disabled by default | ✓ ENFORCED |

## Conclusion

All cross-project validations **PASS**. The codebase is compliant with:
- Zero live trading surface exposure
- Zero runtime LLM integration
- Clean public documentation boundary
- Type-law-first design with nightly-enforced constraints

**Status:** VALIDATION_RECEIPT_SEALED
