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. The private halves never leave that session. - It writes the public half to
team/<id>/key.jsonwith its QR image, addsteam/<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/, marks the previous session superseded, and pushes.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).

| Fingerprint (record, signing) | sha256:956934e47063ceaa |

| Encryption fingerprint | sha256:06c6ccddb7476629 |
| Confirmed | by the editor, Dinis Cruz, in the conductor's session on 29 October 2026 ("yes that is the one") |

| Use | seal a vault key to it (pki-agent.mjs seal --to sha256:956934e47063ceaa, or sgit pki encrypt --recipient sha256:06c6ccddb7476629); only the vaults manager can open what is sealed to it |
The key file (both public PEMs) · seal a secret to it on pki.sgit.ai
As data: keys/index.json. The pattern is the PHP newsroom's, argued in The push is the authorisation.
