G.UX — install on your computer

A drop-in governance kernel for LLM tool dispatch. Twelve gates decide GO / REFUSE / PENDING before any tool call fires.

This package is stdlib-only at runtime. The only dependency is optional PyYAML for constitution files (we'll auto-install it).

macOS / Linux — easiest

Download this folder, then double-click install-gux.command. (On macOS, the first time you may need to right-click → Open to bypass Gatekeeper warnings for an unsigned installer.) The installer will:

1. Verify Python 3.10+ is available.
2. Create a venv at ~/.gux/.venv/.
3. Install the gux-governor package and PyYAML.
4. Write an example ~/.gux/constitution.yaml.
5. Activate a fresh 7-day trial (or activate your paid key if you pass one).
6. Drop a launch-gux.command on your Desktop you can double-click to start the sidecar.

To start with a paid license:

./install-gux.command gux_pro_aB3kD9eF…YOURKEY

From a terminal

# pip install
pip install gux-governor[yaml]

# Or develop locally against this source tree
cd package
pip install -e ".[yaml]"

Then:

gux init                       # write example constitution.yaml
gux trial                      # start a 7-day trial (or...)
gux activate gux_pro_…         # ...activate a paid key
gux serve                      # run the sidecar on http://127.0.0.1:7421

Activating a paid key

License keys look like gux_<plan>_<random> — gux_hobby_…, gux_pro_…, gux_team_…, gux_oem_…. They live at:

• macOS / Linux: ~/.config/gux/license.json
• Windows: %APPDATA%\gux\license.json

Activation is local-only. We never phone home, never check a remote service, never validate against an issuer. The license file is yours.

gux activate gux_pro_aB3kD9eF2…
gux license     # show current plan + days remaining

Talking to the sidecar

Once gux serve is running, every dispatch is one HTTP call:

curl -s http://127.0.0.1:7421/v1/dispatch \
  -H 'Content-Type: application/json' \
  -d '{
    "instance_id": "my-agent-01",
    "tool_name": "memory_recall",
    "tool_version": "1",
    "args": {"query": "what did we decide about Q3 retention?"},
    "session_id": "sess_abc123"
  }'

Response shape:

{
  "verdict": "GO",
  "pipeline_ms": 1.3,
  "trace": [
    {"gate": "HardwareQuarantine", "verdict": "GO"},
    {"gate": "TaskUsageCap",       "verdict": "GO"},
    ...
  ]
}

Audit chain

Every dispatch lands one line in ~/.gux/audit_chain.jsonl. The chain is sha256-linked — entry_hash = sha256(prev_hash + canonical_json(event)). Verify integrity at any time:

gux verify
# or:
curl http://127.0.0.1:7421/v1/audit/verify

Uninstall

rm -rf ~/.gux ~/.config/gux ~/Desktop/launch-gux.command

That's it — no daemons running, no system files to clean up. G.UX is a sidecar, not a system extension.

Where to go next

• Edit ~/.gux/constitution.yaml to add your real agents and tools.
• Wire your LLM dispatch through the sidecar — same shape in, deterministic verdict out.
• Use gux dispatch '<json>' for one-shot testing without the sidecar.
