The blank screen was self-inflicted and the earlier explanation was wrong. The FMP3 marker at 0x100000 is an ordinary state record -- generation, image_size, image_crc32, firmware_slot/slot_inv, config_bank/bank_inv and a matching state_crc32 (0x661286F1) -- not a pending flag. What actually happened: a firmware uploaded over a state that recorded a different identity made the firmware take the restore/adopt path, which draws nothing (panel 1024/1024 bytes zero) while the serial banner printed normally. Restoring the untouched dump fixed it at once (485/1024 bytes lit) and the three apps reinstalled and were confirmed by 0x0730. Clearing the marker sectors was tried twice (a whole 8 KiB, then just the 24-byte headers) and is not a fix: it sends the firmware down MB_MARK_MISSING = fresh radio, which adopts the running firmware slowly and without drawing, and its own write-back restores the marker anyway. AGENTS.md and AGENTS.zh-CN.md now say so in place of the wrong claim. apps/minesweeper/ adds our own 9x9 minesweeper for the 4 KiB overlay: no left/right keys exist on this radio (so the cursor walks with UP/DOWN and digits pick a row then a column), 81 cells need three 9-byte bit arrays rather than a uint16_t mask (the uint16_t version compiled fine and was wrong past cell 15), mines are placed after the first reveal so it cannot lose immediately, and the source compiles clean under gcc -Wall -Wextra -Werror against upstream's real app_api.h. It has not been built for ARM or run -- no toolchain here -- and the README says so.
