export const usage = `pgh attach <file> — upload a file as a content-addressed attachment

Uploads <file> to the pear-git-v3 daemon over the local UDS (calls the
upload-attachment RPC) and prints the resulting oid. The daemon reads the file
directly by path — no base64 — so it must run on this machine (local UDS).
Serve it back at /files/raw?path=/attachments/<oid>; it replicates cross-daemon
over the V2 overlay. Local UDS = the daemon owner (trusted); no session needed.`

  // (no base64 blowup on large files). Cross-machine callers can send { data }.
