Impossible Mission E028: twelfth puzzle piece and safe return

Research diary

Latest milestone: twelve puzzle pieces retained

12 of 36 pieces, 0 of 9 password letters. The game is still incomplete. E028 collects a new fragment from the small right object at 208/98 in Room22. Every one of the eleven earlier inventory masks is preserved. SNOOZES remain 0 and LIFT INITS remain 6. No new death; three previous ordinary deaths remain. Independent inventory HUD 1:06:38.

The 45.12-second silent replay labels three retained initial laboratory episodes, with zero intermediate restores inside each. The agent crosses two clear upper gaps, observes the lift’s actual 50 → 98 → 50 stops, and searches with two half-second slices and explicit neutral pauses. It returns by lift, leaves through the original Left50 doorway, and independently scans the pocket. This is development evidence; uninterrupted normal-boot completion remains outstanding. The twelve observed masks still have no zero-overlap quartet in the current offline analysis. No password letter is claimed.

633 actual RGB observations,30.956914 measured PAL seconds. Three retained source episodes, zero intermediate restores per episode; three unpromoted Room22 tests excluded. Full decode and seven final-video frame checks pass. The successful search completes before physical retreat; longer interrupted search persistence remains unproven. No new death or password letter is claimed.
