chore: Remove Kong references, make infrastructure examples generic
Replaced Kong-specific examples with generic infrastructure scenarios:
- Known-answer questions: database timeout, model loading, GPU memory
- K8s manifest: generic timeout annotations (cloud-provider agnostic)
- Removed Kong timeouts, routes, plugins
- Added gateway configuration guidance for various platforms
- Updated HF token secret management
Benefits:
- System is now cloud-provider agnostic
- Works with any gateway (Istio, Nginx, cloud LB, etc.)
- Examples are more universally applicable
- Easier to adapt to different infrastructure
Affected files:
- verify/known-answers.yaml (3 generic scenarios)
- M3.4-GATE.md (updated expected answers)
- k8s/apps/llm-serving/memory-isvc.yaml (cloud-agnostic setup)

feat(M5.4-M5.6): Add vLLM serving, training loop, and gate infrastructure
M5.4 — vLLM LoRA Serving Setup:
- VllmConfig struct: base model, LoRA config, adapter modules
- Container args generation for K8s deployment
- Support for multiple adapter modules (memory-v1, memory-v2, etc.)
- K8s InferenceService manifest (memory-isvc.yaml) with:
• vLLM v0.11.0 container
• LoRA flags (--enable-lora, --max-lora-rank 32)
• Kong timeout annotations (120s read, 30s connect)
• Startup probe (generous failureThreshold for model load + torch compile)
• Readiness/liveness probes
• Service account + PVC for adapter storage
M5.5 — verl Training Loop:
- VerlTrainingConfig: hyperparameters for RL training
- Trajectory-level + turn-level loss blending (α = 0.9)
- Adaptive batch sizing based on corpus size
- Configuration validation
- verl-training-harness.py: full training script (Python)
• Loads trajectory JSONL format
• LoRA adapter configuration via peft
• Policy gradient loss computation
• Checkpoint saving per epoch
M5.6 — M5 Composition Gate:
- Gate criteria: return-over-baseline >= 10%
- Loss convergence verification
- Format/reward distribution checks
- Overfitting detection (validation vs training loss)
- Checkpoint promotion on pass/rollback on fail
- Full end-to-end signal verification
