"**Evening finale -- the fault is INSIDE the RIO card cage, and tonight's session data "
"separates three tangled threads:**\n\n"
"**1. The smoking gun: the RIO's own self-test.** FAILURE.LOG (881 install) records "
"`missing_board@Slot=3` (addresses 0 and 2), `Slot=4`, and `Slot=5` -- the master board is "
"alive on the serial link but THREE daughter boards fail its internal scan, and the dead-lamp "
"roster (whole AuxUpperRight bank, Tesla relays, PanicButton, Icom relays, FloorEntry) maps to "
"hardware those cards host. The ~13s answer-then-mute pattern reads as the master's retry "
"grace window expiring (rRetry=4 at init, every boot). **The USB adapter is exonerated** "
"(USB re-enum did not revive; the master talks fine).\n\n"
"**2. The cab tester's live session measured the intermittency precisely:** mute windows with "
"reply age peaking at **16.8 s** and three consecutive 5 s windows of ZERO analog replies -- "
"then multi-minute stretches at age 0-32 ms, flawless. 'It started working after I switched "
"mechs' is the fault's quiet spell, not a fix -- no mechanism connects mech choice to the "
"serial cage. ('Left pedal runs on ~1-2 s after release' noted as a watch item -- fits stale "
"counts from a wobbling card.)\n\n"
"**3. Red herring closed:** 'stick won't rotate torso in ADV' was a FIXED-TORSO chassis "
"(Blackhawk/Owens class -- named in the 1995 manual). Authentic; tester self-resolved.\n\n"
"**Leads for tomorrow (hands-on):** reseat/power-check the daughter cards in slots 3/4/5 "
"(cage-side, not the desk-side adapter); the 5V/12V-under-load meter check stands; and ask "
"Cyd about the **RIO EEPROM quirk** he once found (tester recollection -- not in our notes; "
"could bear on the board's scan/config).\n\n"
"Positive field confirmations from the same session: radar V working ('awesome') and CROUCH "
"working on the real cab.")
