What was broken MM submission history and artifact dialogs used legacy layouts. History lacked working artifact navigation, Download all was unavailable, and Community App modals used the old backdrop and container shadows. Root cause The dialogs retained separate legacy markup and styles, and the shared Modal defaults had not been updated for the new design system. What was changed Add the MM history table with submission IDs, sortable dates, member handle, score states, and artifact actions. Restyle artifacts with submission metadata, example-only access before completion, and a single ZIP download after completion. Reuse API authorization and the existing ZIP utility, surface request failures, and apply a 50% black backdrop without shadows to shared Community App modals. Document the shared defaults and download helpers. Any added/updated tests Add 17 regression tests covering artifact visibility, individual and bulk downloads, failure handling, history sorting and navigation, and shared themes. All 494 tests and 141 snapshots pass; 23 previously skipped tests remain skipped. Lint and the production build pass. Headless browser checks with mocked API responses verify desktop/mobile layouts, modal transitions, backdrop styles, and an actual ZIP containing all four artifacts.

Marathon Match submission history and artifact dialogs used legacy layouts. History had no working artifact action, Download all was missing, and Community App modals still used the old backdrop and shadows.
Root cause
The dialogs retained legacy markup/styles, and the shared Modal defaults had not been updated for the new design system.
