Week 1 Briefing: Credentials

The opening Briefing — what has to be true before anything under the soil counts as "a network," and the ground rules for keeping this course's central metaphor honest.

Credentials — what it takes to be recognised as a network at all
Phenomenon
Mycorrhizal symbiosis basics: hyphae, the arbuscular/ectomycorrhizal split, and what counts as evidence of connection rather than mere proximity

Before the session

Read the assigned primer on mycorrhizal structure. Bring one claim about “the wood wide web” you have picked up outside class — a documentary, a headline, a conversation. You are not defending it. You are putting it on the table.

In the session

We build the credentials test together: for a plant-fungus pairing to earn the word “network” in this course, what has to be shown? Movement of carbon or nutrients, not just fungal presence. More than one host connected through a shared fungal individual, not just the same species growing nearby. Every later week’s diplomatic label has to clear this bar before it is allowed to sit on top of a real phenomenon.

Afterwards

The test agreed here is the standing check for the rest of semester. Refer back to it before accepting any week’s metaphor at face value — including the convenor’s.

The spec

What you bring to the session. Written so a reader can tell whether it has been met without asking you.
