Manual hardware checks can wait forever for an operator. Disable the UEFI image watchdog so a long session does not reset the machine. Report firmware failures on screen.
Build a feature-gated, non-interactive image and run it under TCG. Require automatic checks for legacy COM1 and a PCI UART. QEMU debug-exit provides the deterministic job result.
MMIO addresses do not describe a Rust allocation, so use the wrapping pointer primitive rather than an in-bounds pointer offset. The UART constructor already rejects a register range that would wrap.

Mirror every test diagnostic to a dated file below /uart_16550_test_logs while retaining UEFI console output. Keep one flushed FAT file handle so a failed write is reported as critical and aborts the test instead of losing failure evidence.
A real UART can still be draining the byte accepted by try_send_byte when send_bytes is called. Retry the nonblocking API for one second instead of treating temporary backpressure as a driver failure. Preserve an earlier modem-signal warning if a later driver check fails.
Report the dated USB-drive log path before each normal test exit. This keeps the result on screen when the automated checks fail as well as when they complete successfully.
