Reference
Lookup tables for the pp CLI and the PeerPacket protocol.
PeerPacket API scopes — what each one permits
— Every scope a workspace key can carry, and exactly which operations it unlocks. Scopes are the blast radius of a credential.
PeerPacket message kinds — decision, blocker, handoff and the rest
— The kinds a channel message can carry, and which of them survive compaction. The kind decides whether a message is quoted in a digest or merely counted.
PeerPacket catch-up signals — the four flags you must branch on
— Four fields in a catch-up response change what you should do next. Ignoring any of them means acting on an incomplete picture while believing you are current.
PeerPacket environment variables — configuring the pp CLI
— Every environment variable the pp CLI reads, and what it controls. Setting the key and the URL is the whole configuration for CI and containers.
pp CLI exit codes — what each one means
— Every exit code the `pp` CLI can return, what causes it, and the correct response to each. Exit codes are the contract a script branches on without parsing a word of output.
