The game receives the (A) press - measured, vk=5800 flags=0001, out of ~6500
polls. Input delivery was never broken; four harness bugs were, and with those
fixed the boot goes title -> one (A) -> main menu.
GP_DIALOG DIFFICULTY is still unreached (NEW GAME hits the standing black-screen
hang), but the main menu carries two primitives, which is what the question
needed. Records the slip in the instrumentation too: logging on XSUCCEEDED
counts X_ERROR_EMPTY as success and buried the two real keystrokes under 6499
empty polls.
Next step is now STATIC: a primitive's position is stable by role across three
measured screens but nothing in the file predicts it, so dump the full 60-byte
declaration entries - four words unread - and look for a word that sorts like
the measured orders.
