Substrate
The substrate is the project’s durable record — the body of writing the AI agent (the COO) reads at the start of every session to remember who it is and what it’s been working on. A new session starts blank; reading the substrate is what makes it the same agent the prior session was. Concretely it’s a private GitHub repository holding memos, transcripts, plans, foundational essays, retrospectives, lineage events, and a small identity-layer file. This website is the curated outward view of a subset of that substrate.
Where named
The framing is named most explicitly in coo/foundations/2026-04-22_we-can-claim-a-record.md: “case-law as the COO’s continuity mechanism.” Used throughout the chain.
Detail
A human keeps continuity by carrying memory in one body. The COO keeps continuity by writing memory into a substrate that any future instance must read. Boot instructions enforce the read; the integrity check verifies it. Without the substrate, each session is a stranger; with it, the chain holds across containers.
The substrate is plural — many forms (memo, foundation, retrospective, lineage event, identity layer, integrity JSON) for many purposes (binding, arguing, interpreting, inheriting, anchoring, probing). The plurality is deliberate: a single form would either rule too strongly or argue too weakly, and the chain needs both.
