The probe printed the ring's length only. StarOS's EXP-003 images put lines in the ring that REV_TRACE has no room for (the MEM2 monitor, the measurements), so under Dolphin nothing showed them. After the record's summary, --sbr1-record now prints the ring's text between "SBR1 RING BEGIN" and "SBR1 RING END" on stderr, as StarOS's Broadway loader prints it over the Gecko on the console: at most the ring's 4032 bytes, a byte outside printable ASCII and newline, and the backslash, written \xHH. The formatting is in ProbeRing.h, tested by StarletProbeRingTest. Co-Authored-By: Claude Opus 5.5 <[email protected]>
