Full changelog

MartinLoop 0.4.5 — MartinLoop Arcade

0.4.5 ships the MartinLoop Arcade: a terminal Space Invaders game that plays while a governed run works in the background.

What changed

  • MartinLoop Arcade launches automatically when a governed run has been running for 30 seconds in an interactive terminal
  • The game prompts once: "Still working. Play MartinLoop Arcade while you wait? [y/N]" — default is No
  • Accepting starts Space Invaders while the governed run continues uninterrupted in the background
  • The game closes automatically when the run completes, and the real result, receipt, and exit code are preserved
  • Terminal state (cursor, input mode, screen) is fully restored after the game exits under all conditions including errors and Ctrl+C
  • --arcade flag starts or offers the game immediately without waiting for the 30-second threshold
  • --no-arcade disables the prompt entirely for that run
  • The prompt never appears in CI, piped output, JSON mode, or non-interactive agent execution — it is opt-in only

Why it matters

Long governed runs can take several minutes. The arcade keeps the terminal useful without interrupting the run or compromising its receipts. The game is themed around MartinLoop's job: the player is the governance engine defending the budget from Token Spenders, CPU Hogs, API Callers, and Budget Drains.
