Summary

Consolidates the C28x tooling and lands a batch of bench-driven fixes across the
flash, UDS, immobilizer, and CAN-live paths, plus new PCS CAN encoders and an
odin .bin-key documentation pass.

Commits

chore(c28x) — consolidate C28x tooling under scripts/c28x/, correct stale docs
fix(flash) — validate verifyCRC/checkRev response status (was silently "OK")
fix(flash) — PCS/PM *bl targets the CPU2 region → module 0x0C; *bu stays 0x00. Fixes NRC 0x22 on the bootloader-image flash. SCRIPT_BL now waits for the bu update agent before DSC.
fix(uds) — tolerate single-node-bus TX errors during the BL handover (error-passive controller right after reset is expected, not fatal); Phase-2 3E 00 → 7E 00 is the sole arbiter. Case-insensitive node-name resolution.
fix(immo) — pair only persists KEY/SALT when the DI RESPONSE matches the locally-derived value; --save-on-mismatch to override.
feat(can_live) — /ws-raw raw-CAN WebSocket + send UI, per-ID rate limit (~20/s).
feat(pcs) — CAN encoders/validators for the PCS 0x441 protected control frame and vcfront frames (from variant-411 RE).
docs(odin) — pin the TM3_BIN_KEY location in dump_odin.py (constant C in odin/platforms/binary_metadata_utils.py) + decode recipe; ignore _bl_work/.claude.

Validation

dump_odin.py run end-to-end against the 2024.8.9 dump: extract → detect (py3.10) → decompile (1487/1514 ok). Recovered constant C matches TM3_BIN_KEY in .env exactly.
Flash / handover / immobilizer changes are bench-driven (12804 PMR); see commit bodies for the device-confirmed details.

## Summary Consolidates the C28x tooling and lands a batch of bench-driven fixes across the flash, UDS, immobilizer, and CAN-live paths, plus new PCS CAN encoders and an odin `.bin`-key documentation pass. ## Commits - **chore(c28x)** — consolidate C28x tooling under `scripts/c28x/`, correct stale docs - **fix(flash)** — validate `verifyCRC`/`checkRev` response status (was silently "OK") - **fix(flash)** — PCS/PM `*bl` targets the CPU2 region → module `0x0C`; `*bu` stays `0x00`. Fixes NRC 0x22 on the bootloader-image flash.
