FastRIO certified: 31250v2 final runs clean; config plumbing for baud/poll

Operator-verified zero lamp misses/hangs through the slow-chord test
(62500's killer) and 392/min mash. Final run: NAK=0, 25 timeout resends
silently healing inbound response loss, counters flat, zero wedges.
--poll 20 delivered ~31Hz analog (1.7x legacy); the shortfall vs 50Hz
is additive host pacing (delay after awaited exchange), not board
saturation - noted as a future host tweak.

AppConfig gains RioBaudRate (default 9600) + AnalogPollMs (default 55),
plumbed through RioCoordinator; existing configs unchanged. Production
matrix recorded in ANALYSIS.md: 9600 patched chip for native-game
cabinets, 31250v2 + poll 20-25 + FTDI for RIOJoy cockpits.

ordinary electrical noise, and its retries are near-zero on clean links).

## FINAL CERTIFICATION (2026-07-19) — 31250 v2 ships
Operator-verified at 31250 v2 with stop-and-wait active: **zero lamp
misses/hangs** through the slow-chord test (the exact scenario that
condemned 62500) and a 392-presses/min mash.
`testlogs/riomash-31250v2-final`: analog 89.0% (structural), **NAK = 0**,
25 resends — all timeout-triggered, i.e. the retry machinery silently
healing occasional INBOUND response loss (29 host-side framing events),
which is exactly the insurance it exists to provide. Counters flat,
zero wedges, gaps <100ms except run-start/stop artifacts.
`testlogs/riomash-31250v2-poll20` (--poll 20): delivered ~31 Hz analog
(2036 replies/65s) vs the legacy 18 Hz — 1.7×. The 62.6%-of-slots figure
is a host artifact, not board saturation: the poll loop delays AFTER each
awaited exchange (~6-9 ms), so the real cadence is interval+exchange.
Absolute-schedule pacing would approach 40+ Hz; ~94% of actually-issued
polls were answered. Future host tweak, not firmware.
### Production configuration
| deployment | chip | config.json |
|---|---|---|
| native-game cabinets | `RIOv4_2_patched.bin` (9600) | defaults (RioBaudRate 9600, AnalogPollMs 55) |
| RIOJoy-only cockpits (FastRIO) | `RIOv4_2_patched_31250v2.bin` | RioBaudRate 31250, AnalogPollMs 20-25, FTDI-class adapter |
AppConfig.RioBaudRate + AnalogPollMs are plumbed through RioCoordinator;
stop-and-wait delivery is always on (near-zero cost on clean links).
Firmware images, hashes, disassemblies, the mechanized mash harness, and
all eleven bench logs live in this directory. The original AMD chip is
retired, preserved unmodified.
