[v1.5.0-STABLE] - 2026-06-03

Name: Peridot v1.5.0-STABLE: Split Tensor Allocation & Sovereign Kernel Architecture

14B Model Pivot & Split Tensor Allocation: Bypassed the planned 7B tier and transitioned the core inference weights to the high logic Qwen2.5-14B-Instruct-Q4_K_M to permanently resolve RAG hallucinations. GPU_LAYERS in config.py was adjusted to 20, safely splitting the 14B parameter load between the 8GB RTX 5050 GPU and Ryzen 7 CPU RAM.
Structural Watchdog Hardening & VRAM Purge: Completely upgraded the _execute_vram_purge method inside the VRAM State Machine. Integrated direct NVIDIA driver querying via pynvml to calculate actual reclaimed physical bytes before allocating tensors, bypassing unreliable OS cache metrics.
FSM Panic Tuning & Hardware Ceiling: Enforced a strict 7500MB FSM hard ceiling for display driver preservation. Lowered the VRAM purge safety threshold from 1.5GB to 200MB, preventing recursive 503 errors under the new 14B load. If the GPU fails to clear thresholds within a 2.0-second timeout, the FSM instantly trips a KERNEL PANIC.
System Prompt Hardening: Re-engineered build_system_prompt to intercept RLHF conversational tropes. Injected explicit constraints forcing the model to refuse queries outside of provided RAG contexts, neutralizing knowledge-bleed defects.

Multi-Tab Notebook Migration: Replaced the legacy single-buffer UI with a ttk.Notebook framework, introducing three sectors:
- CHAT MATRIX (Text Generation)
- KERNEL VAULT (Live RAG tracker)
- SETTINGS (hardware configuration)
Control Console UI & Live Telemetry: Deployed an industrial, low-overhead administrative dashboard fetching from the secured /telemetry/stability endpoint. Displays live FSM states, dynamic system health scores, total inferences, and panic counts.
Research Core Toggles: Integrated UI control switches mapping to internal /telemetry/enable and /research/disable HTTP pathways, allowing operators to authorize or suspend Folding@Home cycles directly from the interface.
Hardware-Aware Model Swapper: Engineered a dynamic directory scanner that evaluates local .gguf file sizes against the 8GB RTX 5050 VRAM envelope. Assigns runtime compatibility ratings ([HIGH], [MEDIUM], [LOW/CRITICAL]) and supports GUI hot-swapping through config.py rewriting.
144Hz Kinetic Scrolling: Replaced Tkinter's default scroll behavior with a custom 5ms (200Hz) sub-pixel velocity decay loop for high refresh rate rendering.

Standalone Command-Line Ingestion (ingest_vault.py): Added an isolated CLI script to parse, chunk, embed, and commit files directly to the FAISS L2 database without touching the GUI. Embeddings are generated strictly through the CPU-bound Aether-Route.
Binary PDF & Deep Semantic Search: Upgraded ingestion to dynamically decode binary PDF text layers via PyPDF2. Increased FAISS retrieval depth from top_k=3 to top_k=6 for denser multi-document context injection.
Sliding Window Chunking: Replaced the legacy double-newline chunker with a strict character-clamped fragmentation system (<800 characters) to improve vector precision and reduce dilution.
Staging Cleanup Automation: Processed files are automatically relocated from input/ to input/processed/ to prevent recursive re-ingestion and maintain a clean archive.

AVX2 Matrix Restoration: Reverted the Python environment to a stable NumPy 1.x baseline to resolve the fatal C-extension _ARRAY_API crash during vector initialization.
Live Buffer Search & UI Extraction: Added a Ctrl+F real-time search overlay with highlight support and a _copy_to_clipboard function for instant Markdown extraction.
Global Instantiation Fix: Patched a catastrophic NameError crash loop by explicitly instantiating PeridotProductionKernel() in the global scope before engine boot execution.
Git Integrity & Cleanup: Updated .gitignore to block transient FAISS binary files (aether_cold_storage.db) from entering version control. Executed a cleanup sweep locking configuration, UI, and backend changes into the stable origin/main tree.
