feat(runtime): add ProductionDebtBitNetGate and TechnicalDueDiligenceLedger

[Ahmed Hassan (AAH20)]

Summary

Adds the native ProductionDebtBitNetGate and cryptographic TechnicalDueDiligenceLedger under utils/production_debt.py.

Problem Solved

As enterprise AI architects and Forward Deployed Engineers deploy 1-bit LLMs (BitNet b1.58) and matrix-multiplication-free ternary networks across CPUs, NPUs, and accelerators, engineering organizations require real-time controls over Enterprise 1-Bit LLM Production Debt & Technical Due Diligence:

1. BitNet Debt Index (BDI <= 12.0): Scoring 1-bit inference runs for ternary weight clipping saturation errors, 8-bit dynamic activation scaling drift, ternary kernel latency degradation, and SIMD register unpacking bottlenecks.
2. Dynamic Activation Scaling Multiplier (DASM <= 1.08x): Monitoring peak utilized dynamic activation buffers against base ternary weight allocations to prevent activation overflow and integer precision degradation.
3. P99 Ternary Kernel Latency Ceiling (<= 12.0us): Enforcing strict execution boundaries across ternary addition and bit-packing unpack routines.
4. Deterministic Mutation Boundaries: Enforcing never_equate_intent_to_approval across state-mutating ternary weight quantizations, dynamic scaling factors, and GGUF serialization pipelines.
5. Cryptographic Technical Due Diligence Action Ledger: Emitting immutable, SHA-256 hash-chained JSONL receipts providing audit-ready evidence for VC/PE Technical Due Diligence, M&A evaluations, and enterprise production readiness reviews.

Features Added

• utils.production_debt.ProductionDebtBitNetGate:
  • evaluate_1bit_inference(): Evaluates dynamic activation memory ratios, ternary clipping saturation errors, and kernel latency, returning a normalized Production Readiness Score (0–100) with critical smell warnings.
• utils.production_debt.TechnicalDueDiligenceLedger:
  • record_bitnet_event(): Cryptographically links each 1-bit inference run and ternary quantization event into an immutable SHA-256 chain.
  • verify_ledger_integrity(): Validates hash-chain continuity.

Testing & Validation

• Added utils/test_production_debt.py with 3 automated unit tests validating clean 1-bit inference runs, degraded dynamic activation sprawl failure detection, and cryptographic ledger integrity (3/3 tests passing).
