Impossible Mission E021: ninth fragment and live robot return

Latest milestone: nine puzzle pieces retained

9 of 36 pieces, 0 of 9 password letters. The game is still incomplete. E021 collects a fragment from the top lamp in room06. The agent climbs using the linked left and right lifting platforms under an ordinary SNOOZE. When that temporary protection expires during the return, it waits for the actual central robot to move away, crosses a short gap and drops to the clear bottom floor. All eight earlier inventory masks are preserved. SNOOZES: 0; LIFT INITS: 4. The inventory proof shows HUD12:41:16 with no new ten-minute death penalty. Two earlier ordinary deaths remain in the retained laboratory campaign.

The57.68-second silent replay labels three laboratory source episodes. Each source run has one initial private snapshot and zero intermediate restores. The first episode uses the successful ascent prefix and omits a later search dialog calibration failure. The next two show the card, observed SNO expiry, live robot gate and verified original exit. Normal-boot whole-game completion proof remains outstanding.32 layouts have been observed across72 room entries.

Gameplay uses rendered RGB, ordinary joystick actions and observed memory. The robot checks distinguish actual body pixels, avatar white ink, lifting stripes and recognized search/reward dialogs. Separate emulator raster diagnostics account for timing; no gameplay RAM coordinates, hidden contents, trainer or game memory writes are used.

Route and verification

The lamp yields the ninth fragment after a climb through linked lifting platforms. Temporary protection expires on the way back. The controller waits for the central robot to move Right, then crosses a short gap and descends to the clear bottom floor. It uses the original exit and verifies all nine masks. The fireplace was tested separately and was empty; that lab branch is unpromoted.

The57.68-second replay contains998 actual RGB observations. Full decode and 49 frozen source entries passed verification. The complete three source runs charged436.329431 execution wall seconds; this includes the first run’s omitted suffix and excludes other campaign trials. Three initial laboratory snapshots, zero intermediate restores per source; game incomplete. No agent GPU allocation. No ROM, private snapshot, raw RAM dump or executable is distributed.
