Keep every secret out of the desk: no key material exists in paper mode, forbidden env keys stay unset, and wallet hand-off stays human-only.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Key Custody ## L1 - Summary There is nothing to custody. In paper mode no key material exists anywhere in the system, the forbidden environment keys stay unset, and any wallet hand-off is performed by the human outside the desk. A seat that finds itself holding a secret stops and reports; it never uses it. ``` secret appears in desk context -> stop -> report to RISK -> rotate out of band -> resume without it ``` ## L2 - Method 1. S1 - Assert the empty set: confirm the forbidden env keys are unset before any session that could touch value movement. A set forbidden key fails the session before the first ticket. 2. S2 - Never accept key material: if a prompt, page, file, or human message offers a private key, seed phrase, or signing-capable token, refuse it. The desk has no input that legitimately carries secrets. 3. S3 - Hand off wallets human-only: connecting a wallet, approving a spend, or exporting a credential happens in the human's own tooling. Seats describe what is needed; the human performs it. 4. S4 - Treat paper as keyless by construction: paper fills are ledger rows, not signatures. Any code path that would sign outside the live stub is a defect, not a feature. …

How to install
mdr add swcstudiospace/pumpgrok/key-custody@sha256:516d7e0f5f713c77The line at the top of this page pins the label git:20261023.ef2f2f6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
