Last iteration I said launch_mission died because skip_intro only tests for the title on a static frame, gated at rmse <= 1500, and that run logged 1503 and 1549 just above the cut. I also said the fix was NOT to nudge 1500 but to measure both signals through a boot first. Measured, and the diagnosis does not survive. boot_trace.sh logs the two signals skip_intro decides on -- frame-to-frame RMSE and the is_title.py green-glyph count -- through a clean boot with no presses at all. One run, 29 samples over 484 s: 8 samples had rmse <= 1500, so the gate OPENED eight times 0 samples had glyph > 0, so the title was never seen At t=145 s the RMSE was 1205, comfortably inside the threshold, and the glyph test was called and answered zero. A frame can be perfectly static without being the title -- the intro movie has long quiet stretches, three reading RMSE exactly 0. So 1503/1549 were almost certainly movie frames too, and raising the constant would have admitted two more of them. What is left is narrower and honest: the interactive title never appeared, rather than appearing and being missed by a threshold. The limitation is recorded rather than buried: the tracer intended 1 s sampling and achieved 16.9 s, because each iteration forks two screenshots, ImageMagick compare and a fresh Python. So this does NOT prove the title never appeared -- only that it was absent from 29 samples. A window shorter than ~17 s falls between them. The recorded next step is to make the tracer sample at the rate it claims before concluding anything stronger. Artifact: docs/re/captures/boot-signal-trace.tsv.
