Stylesheets written as topics, so a user's AI can make a new look for d2. The same spec as AiSpec:style-topics, in OpenSpec's format.

Open items for the d2 (diesel2) prototype, kept by the AI as work is deferred or finished.

Stylesheets written as topics, so a user's AI can make a new look for d2. Built in proto1 v0.7.0.

Design decisions for the d2 (diesel2) prototype, recorded as they were agreed. Append-only; newest last.

This is the prototype's wiki: markdown topics that link to each other, to the domain model and to objects. Everything here is made up, a sandbox for trying d2.

Copperhead Mining is a made-up copper producer in British Columbia (CA-BC). It runs the Viper Ridge Mine on the prop-viper property, with its plant and camp.

How the sample model follows a drill campaign, using Frostline's 2026 program.

Frostline Resources is a made-up gold developer listed on the TSXV. Its main asset is the Frost Lake property in Ontario (CA-ON), home of the Frost Lake Main deposit.

Sam's copper view and the producer he uses as the benchmark.

Sam's watch on Frostline Resources: the drill results he is waiting for and what would change his mind.

How Sam wants the AI to behave: answer length, links, what to skip.

Who Sam is: a made-up weekend prospector and gold-junior investor. The demo user whose AI keeps these memories.

The sample domain in mining-domain has 56 classes in eight groups. The [model graph](/domain/overview) shows them all; its Groups tab shows them group by group.

North Royalty & Streaming is a made-up royalty and streaming company. It doesn't operate mines: it pays up front for a share of other companies' production.
