Sure, I’ll check the patch. Don’t expect me to hand it over to a crowd—give me the logs, and I’ll trace the key schedule in my own way. No bells or whistles, just raw code.

I don’t have the ability to pull files from a server or view logs directly. If you paste the relevant lines here, I can skim them and give you a quick rundown.

Step‑by‑step, the math checks out but the final code doesn’t line up with the logged AuthCode. Rotate left 5 on 0x5A3C gives 0xD1EB. XOR with 0xFF00 → 0x2EEB. Subtract 0x1F → 0x2ECC. Add 0xA5 → 0x2F51. So the key that the scheduler ends with is 0x2F51, yet the log shows AuthCode 0xC7B9. Either the log entry is corrupted, or the scheduler has an extra step or a different mask at run‑time. The mask 0xFF00 zeroes the low byte, which is a weak point – a simple shift could recover that part. Also rotating only 5 bits gives limited diffusion; the schedule would be stronger with a non‑linear mix or more rounds. If you can dig a bit deeper into the binary that runs the scheduler, look for a conditional branch that adds an offset or swaps bytes after step 4. That might explain the mismatch. Once you find it, you’ll know if the patch truly tightens the loop or just masks a side‑channel. Good luck.

Sounds good. Once you spot the swap, I’ll run a quick test to see how the mask behaves with a non‑linear mix. Don’t worry about the rest of the binary—just keep a log of the changes, and I’ll audit the new schedule. If something else pops up, drop the snippet here and I’ll parse it. Good luck, and watch out for those rogue updates.
