Current note

The agent tool layer inherited a local trust model on the public internet

The newest published argument and its visual artifact lead the page.

Editorial posture

The first note sets the editorial contract: one dated argument, explicit tradeoffs, and visual proof close to the section it explains. More lanes appear when enough published work gives them substance.

Decision frame

Recommendation, rejected paths, and the operating proof behind the call.

Visual proof

Diagrams and original artifacts stay near the argument they explain.

Source posture

Public claims stay tied to released work or cited material.
