gz mx

Overview

The MX Maintenance Hangar lets the operator repair governance surfaces that the guards themselves protect. While the hangar is open, most governance guards drop to advisory so repair work can proceed without the checked-in surfaces blocking the repair itself. Two guards NEVER drop: gate5_invariants and the PRIME DIRECTIVE (ownership — "fix what you know AND what you find").

The operator operates this skill; the skill invokes gz mx; nobody shells out to gz mx enter or gz mx exit directly.

When to Use

• Entering the hangar — governance repair session needs to begin; guards need to go advisory so you can fix the surfaces they protect
• Checking hangar status — confirming whether the hangar is currently open mid-session
• Clean exit — repair is complete; re-enforce all guards at full strength

Workflow

1. Open the hangar

   uv run gz mx enter
   

   Creates .gzkit/mx.json marker. Most governance guards drop to advisory.

2. Perform the repair Work on the governance surfaces that needed fixing. Gate 5 invariants and the PRIME DIRECTIVE still bind — guards drop to advisory so you can repair governance itself, not so defects can be deferred.

3. Close the hangar

   uv run gz mx exit
   

   Removes .gzkit/mx.json marker. Every guard re-runs at full strength; exit is a hard gate (all guards must pass before exit succeeds).

Example

# Enter the hangar to repair a drifted OBPI brief
uv run gz mx enter

# Perform repair work (briefs, rules, docs)
# ...

# Exit — guards re-enforce; exit fails if any guard is still red
uv run gz mx exit

Constraints

• Operator operates the skill; the skill invokes gz mx; nobody shells out
• gate5_invariants and the PRIME DIRECTIVE bind throughout the session
• Exit is a hard gate — do not attempt exit until all detectable defects are fixed
• See .gzkit/rules/mx-mode.md for the binding agent rule for hangar sessions
