57 Kilometres of Rock, Read as One Fibre: The Gotthard's Digital Twin
How distributed acoustic sensing turns a single fibre into 57 km of strain gauges — and where BIM ends and the Gotthard's decision-making digital twin begins.
Graph engineering: the org chart your agents were already drawing
Graph engineering wires agents into nodes, edges and shared state. What's real, what's a LangGraph rebrand, and when a loop is all you actually need.
Review of the Week — W30: The Week PAZ Kaffi Learned to Pin the Decision
W30 recap: PAZGPT in Archicad, NVIDIA open-weights provenance, EPFL's 30% solar cell, PSI's solid-state battery, and why every AI output needs a pinned hash.
Opus 5 Rebuilt a Part From Pixels Alone — Read the Provenance
Claude Opus 5 reconstructed a machine part from a drawing it couldn't see. What that means for AEC reconstruction — and why every agent output needs a source stamp.
Before a building can feel itself, someone must learn to build the system
PAZ opens Building System Specialist Title XIV on 1 Sept 2026 — five months, six hours a week, teaching Grasshopper-and-Archicad system-building over manual drawing.
Open weights are a provenance instrument — pin the checkpoint before you ship the drawing
NVIDIA put 650 open models and 250 datasets on Hugging Face. For architecture offices the payload is not speed — it is a checkpoint you can cite.
The Constitutive Model: What a Material Promises, Written as Code You Can Falsify
What a UMAT really is, why return mapping conserves volume, and the one question to ask your engineer before signing off any FEA result.
Synthace's ChatGPT-in-the-lab is a three-layer architecture — and AEC has the same shape
Synthace put ChatGPT inside a biology lab using a context-aware prompt, JSON contract, and error-feedback loop. AEC runs the same three-layer shape.
PSI's 80°C Battery Trick: Solid-State Storage Learns to Last 1,500 Cycles
PSI's mild-sintering plus 65nm LiF coating keeps a lithium-metal solid-state cell at 75% after 1,500 cycles — and what it means for building-scale storage.
Your Office Wiki Is a Folder of Markdown Files — OpenKnowledge Just Made It Editable
OpenKnowledge turns a folder of markdown into an AI-readable office wiki over MCP — and keeps your practice's knowledge in files that outlive the vendor.
