pnasyscnct — tailscale-style Pi remote (computer + Pi)

One package, both ends. Install on Windows 11 (TPM 2.0) and on Pi 4/5 (Raspberry Pi OS, headless or desktop) — via pip or via GitHub, identical:

pip install pnasyscnct
# or:
pip install git+https://github.com/Powerentity303/PNASystems_CRP.git
# or the one-liner (venv-safe on Pi OS):
curl -fsSL https://raw.githubusercontent.com/Powerentity303/PNASystems_CRP/main/installer.sh | bash

This gives you both commands: pnasyscnct (computer) and pnasyscrp (Pi).

Computer

pnasyscnct setup            # same questions + TPM-sealed vault, prints computer ID
pnasyscnct setup --ssh      # scan for the Pi's pairing request, verify, rotate link key
pnasyscnct ssh MyPi         # asks link encryption key, remote shell (reconnects)
pnasyscnct mcp --enckey K --sshdev MyPi   # MCP server (OpenCode), SSH always active
pnasyscnct update           # reinstall latest (cache-busted)

OpenCode (opencode.json):

{"mcp": {"pnasys-ssh": {"type": "local",
  "command": ["pnasyscnct", "mcp", "--enckey", "LINK_KEY", "--sshdev", "MyPi"],
  "enabled": true}}}

Pi

pnasyscrp setup             # identity + AES vault (overwrite confirm, old-file cleanup)
pnasyscrp enable            # listener + fresh session key (10-min idle auto-off)
pnasyscrp ssh setup         # pairing: key first, code issued, computer ID + device name
pnasyscrp ssh enable        # presence + listener (root-aware exec)
pnasyscrp update            # reinstall latest (cache-busted)

Linking in short: computer setup --ssh scans → Pi ssh setup sends an encrypted pairing code to that computer ID → computer verifies with the pairing key, both adopt a fresh link key → Pi verifies the answer the same way. Vercel only relays opaque blobs. Pi exec runs root-aware (sudo -n when not uid 0).
