Bot findings (Copilot/Codex): no-op board_trace_pinmux stubs for lpcxpresso18s37/43s67 (TRACE_ETM otherwise broke their build), SAME70 ID_PIOD clock enable, capture-script duplicate BeforeTargetConnect on the RA references, profile-script support for --no-timestamps itraces. Deep review (whole branch): same70_xplained board row + caveat restored, stale pico2 72 MHz claim corrected to the shipped 48, explicit SetTracePortWidth(4) in the three references that relied on Ozone's default, coverage-cell guard, median-based SysTick calibration, dead session flag removed, stale RA8M1 divider comment fixed (0x02 = /4 is the validated chip max) and the debugger guard indented. EVKB bench findings: only R1884/D3 remains open (D1/D2 meter-verified); RT1176 trace width is 1 or 4 only - J-Link arms the CSSYS TPIU and its own sampler at 4-bit for any width>=2 request; a powered MCU-Link USB breaks the external probe even with JP4 shorted.
