CydandClaude Fable 5 8231bee58c BT410 5.3.68: THE LIVE-RIO FAULT IS FIXED -- it and the TM crash were one defect
The [map] audit named it in one run: subsystem 17 = Torso, attribute ids 12/13
unresolved.  The donor's decompiled torso.hpp carries the authentic enum with
binary offsets -- ids 3..15, including StickPosition(9), TorsoUp/Down/
Left/Right(10-13), TorsoCenter(14), MotionState(15).  Our table stopped at
seven entries with MotionState at id 9, on the strength of a comment claiming
the rest were messages.

The streamed control mappings bind BY ID as direct WRITE destinations, so the
truncation produced two different crashes from one cause: in TM mode the
button ids 12/13 resolved NULL (the boot write-fault the moment the joystick
polled), and in RIO mode the analog id 9 resolved to our motionState
StateIndicator -- every analog packet from a live vRIO wrote raw floats over a
watcher-socketed object, and the corrupted chains walked into unmapped memory
~30-40s later.  That was the 'intermittent' pod fault at the fixed DPMI-host
address.  vRIO down = no analog = no corruption, which is why the norio conf
launched: every observation from the whole hunt drops out of this mechanism.

Fix: the full 13-entry donor table; five int command members carved from the
dynamicsState reserve (class size unchanged); ctor zeros them.

Verified, two agreeing runs each way: TM mode launches with a clean audit and
the Thrustmaster joystick driving the torso (stickY=0.907 -> torsoElev 0.349);
RIO mode with vRIO STREAMING launches, zero faults, weapons cycling.
pod_render_rec is no longer poisoned and the norio workaround is obsolete.

The audit-before-the-archive-call pattern (BT_MAP_LOG walks the same streamed
table CreateStreamedMappings consumes, naming what will not resolve) turned a
two-day intermittent-corruption hunt into a one-run lookup.  The streamed RES
tables are binding contracts on our attribute enums.

CydandClaude Fable 5 1233a1d5f6 BT410 5.3.66: RIO-fault eliminations, and TM mode's own NULL-deref surfaced
Three clean eliminations on the live-RIO fault, all on the ack-fixed emulator:
not the ack heuristic (reproduces after the fix), not the debug logging
(pod_render_quiet faults identically with no BT_* env), and not the failed
test-mode handshake (the quiet run's init PASSED and it faulted anyway).

The Thrustmaster isolator -- L4CONTROLS=THRUSTMASTER so the game never opens
the RIO while vRIO keeps streaming into serial1 -- was blocked by its own
discovery: TM mode dies at boot in ControlsInstanceDirectOf<int>::Update+0x6,
mov eax,[eax+0x1c] with EAX=0, at guest 00485E1A.  That address resolves
cleanly in our map and the loader names BTL4REC.EXE CODE 0x75E1A directly: a
real defect in our controls wiring for the non-RIO path, and its own
reconstruction brick.

Standing facts for the hunt: our exe + live vRIO = fault in ~30-40s; shipped
exe + the same stream on the same emulator = fine (two baselines).  The ISR
and LBE4ControlsManager are archive code; ours in the per-event path are the
mapper (MECHMPPR) and the event/receiver plumbing.
