 "title": "The DTR/RTS reset on ESP32-S3 USB-Serial-JTAG is a system reset, not a power-on reset, and the RTC counter surviving it is how you prove that",
 "symptom": "A host-driven reset is treated as a cold boot, and stage timings are built on that assumption. Some of them then double-count a fixed offset, because the board's own clocks did not restart the way the measurement assumed.",
