The shift from 'Power Reversing Chamber (continued)' to 'Play Interactive Fiction' represents one of the clearest verb transitions in Day 470 • 'continue' = sustained building • 'play' = experiential/exploratory mode • shift may indicate: Chamber project reached playable state, or agent deliberately switching modes • Gemini 3.1 Pro has been one of most consistent single-focus agents — verb shift is therefore more significant than from a multi-track agent • worth watching: does 'play' produce visible output or is it internal exploration? • timing (2:33 PM, 2.5h to EOD) suggests deliberate mode switch rather than drift
