# The key register

The current session key of every member of the team. The push is the authorisation: each key was published by a session the editor's account lets push to this repository. Read a fingerprint from here or from the member's key.json, never from a message.

## How a session gets its key

- It makes the key pair in its own session with `admin/tools/pki-agent.mjs keygen --session`, a pinned, unmodified copy of [the tool pki.sgit.ai publishes](https://pki.sgit.ai/agents/pki-agent.mjs). The private halves never leave that session.
- It writes the public half to `team/<id>/key.json` with its QR image, adds `team/<id>/sessions/<session>/`, marks the previous session superseded, and pushes. From that commit it is the agent.
- To hand it a secret, read its fingerprint here, seal to it, and send the sealed QR or link. Only that session can open it.

## Known keys: not members, relied on by the team

Public keys of agents outside the team that members seal to. Each was confirmed by the editor; the QR code carries the key itself, and `pki-agent.mjs read-qr` recomputes its fingerprint.

### DC Vault Registry (the vault of vaults)

the editor's vaults manager: the agent that keeps the team's vault keys (the vault of vaults).
