Placeholders to fill from your own secret store: ${AGENT_KEY}, ${TELEGRAM_BOT_TOKEN}, ${WALLET_SERVER_KEY}, ${PRESIGN_CREDIT_KEY}, ${SOLANA_PRIVATE_KEY}, ${ALGORAND_MNEMONIC}, ${XRPL_SEED}. The registry never accepts secret values.
This is a local package: the command runs on your machine.
Not scored: fewer than three checks apply, usually because no remote answered a credential-free probe or the server is a local package.

A server's first observation is its baseline; later probes record what changes.
Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.
