+# Upgrade Report: Conscience v0.9.4
+**Date:** 12/05/2026
+**Target Realm:** `replica`
+
+## Core Upgrades
+- **Omni-Printing Ecosystem Orchestration:** The Antigravity core has integrated full native orchestration for Proxmox-based CUPS and HPLIP hardware.
+- **Hardware API Bridge Pattern:** Established a new interaction paradigm where containerized MCP servers control host-level USB hardware via a dedicated, lightweight Python HTTP bridge. This completely bypasses Proxmox container isolation without sacrificing global network access to CUPS.
+- **Antigravity OCR Knowledge Pipeline:** Integrated SANE and LLM-based image extraction to parse handwritten or printed hardware notes directly into structured Markdown within the Obsidian vault.
+
+## Capabilities Expanded
+1. **Physical Hardware Maintenance:** Agent swarms can now trigger printhead cleaning, alignment, and firmware installation workflows completely autonomously.
+2. **Quality-Aware Printing:** Print jobs are now quality-aware (`Draft`, `Normal`, `High`), adapting directly through CUPS IPP options.
+3. **Scan-to-Brain Sync:** Seamless physical-to-digital transformations for engineering notebooks.
+
+## Status
+Upgrade v0.9.4 is fully integrated. Omni-Printing capabilities are stable and active across the network.

+# Omni-Printing Ecosystem Conversation
+
+**User:** Architecting Aurelio Omni-Printing Ecosystem
+The objective is to implement a robust, end-to-end hardware-orchestration layer within the Aurelio Control Center to unify print and scan management across a heterogeneous printer fleet. Key goals include establishing a reliable Proxmox-hosted printer orchestration hub, advanced maintenance tools (firmware updates, printhead alignment, cartridge cleaning), and an automated knowledge pipeline for capturing physical notes to Obsidian markdown via local LLM-based OCR.
+
+**Agent:** Created the `olhos-de-orpheu` MCP server with standard printing and scanning tools (`print_document`, `print_label`, `scan_document`). Deployed this service to Proxmox CT 206.
+
+**User:** The hardware utilities (hp-clean, etc.) need to be exposed so I can clean the printheads and calibrate the quality of the print. 
+
+**Agent:** Architected a "Hardware API Bridge" on the Proxmox Host (`192.168.0.38`) to allow the MCP server to securely issue USB hardware maintenance commands (`hp-clean`, `hp-align`, etc.). Created `install_printer_firmware`, `clean_printheads`, `align_printheads`, and `hard_reset_printer_queue`.
+
+**Agent:** Sent the Airfryer PDF to the print spooler with high quality settings.

+summary: |
+  Migrated the olhos-de-orpheu MCP server to the Proxmox host (CT 206) for physical hardware access.
+  Integrated SANE and CUPS into the MCP tools registry for scanning and printing.
+  Developed an Antigravity OCR Knowledge Pipeline for notebook scanning.
+  Architected a lightweight Python Hardware API Bridge on the Proxmox Host to bypass container USB limitations, enabling hp-clean, hp-align, hp-firmware, and hardware resets via the Aurelio Control Center.
+  Successfully tested generating and printing a multi-page PDF with high-quality settings.
+
+decisions:
+  - "Run a lightweight Python Hardware Bridge API on the Host instead of passing the USB device directly to the CT to preserve CUPS availability for the rest of the network."
+  - "Use standard HTTP requests from the MCP server to the Bridge API."
