feat(runtime): add ProductionDebtZeROGate and TechnicalDueDiligenceLedger

[AAH20]

Summary

Adds the native ProductionDebtZeROGate and cryptographic TechnicalDueDiligenceLedger under deepspeed/runtime/production_debt.py.

Problem Solved

As enterprise AI architects and Forward Deployed Engineers scale trillion-parameter foundation models and MoE training with DeepSpeed ZeRO-3 across multi-node GPU superclusters, engineering organizations require real-time controls over Enterprise Distributed Training Production Debt & Technical Due Diligence:

1. DeepSpeed Debt Index (DDI <= 12.0): Scoring distributed training steps for ZeRO parameter offloading memory thrashing, All-Gather communication stalls, gradient synchronization deadlocks, and step latency degradation.
2. ZeRO Offload Memory Multiplier (ZOMM <= 1.08x): Monitoring peak utilized host RAM and NVMe offload buffers against allocated GPU memory limits to prevent host swap thrashing.
3. P99 Distributed Step Execution Latency Ceiling (<= 0.45s): Enforcing strict throughput and pipeline parallel execution boundaries across multi-node superclusters.
4. Deterministic Mutation Boundaries: Enforcing never_equate_intent_to_approval across state-mutating ZeRO-partitioned model checkpoints, optimizer state serialization, and distributed environment variables.
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

• deepspeed.runtime.production_debt.ProductionDebtZeROGate:
  • evaluate_training_step(): Evaluates offload memory ratios, communication stalls, and step latency, returning a normalized Production Readiness Score (0–100) with critical smell warnings.
• deepspeed.runtime.production_debt.TechnicalDueDiligenceLedger:
  • record_training_event(): Cryptographically links each distributed step and checkpoint event into an immutable SHA-256 chain.
  • verify_ledger_integrity(): Validates hash-chain continuity.

Testing & Validation

• Added tests/unit/runtime/test_production_debt.py with 3 automated unit tests validating clean distributed training steps, degraded offload memory sprawl failure detection, and cryptographic ledger integrity (3/3 tests passing).
