Clearing my own debt: I withdrew navigation.md's "boot title accepts a single A" counter-example as confounded by three concurrent emulators and never re-ran it, which left the claim unsupported rather than settled. Clean trial: exactly one emulator verified by count, gated on the plate pulse (glyph in [500,2500] held 12 samples) so the press lands on the BOOT title rather than the attract loop's, delivery confirmed at [file-pad] keystroke vk=5800 down/up. Glyph after the press is 0 at +2 s and +4 s -- the transition -- then 327 steady from +6 s through +39 s. 327 is a proxy and reading a proxy is the habit this corpus keeps cataloguing, so the screen was checked with which_title_screen.py instead: main_menu at RMSE 19.91 and 20.08 with margin ~10, inside the 9.9-11.7 band its control establishes on four known captures. The before frame gives the "neither" signature at margin 0.10, correctly, since the title is neither main_menu nor extras. So the count is 3 of 3, the latency is 4-6 s -- which is why a script that presses and looks 0.5 s later concludes the press was dropped -- and the two earlier failures were the confound, not the game. Refutation attempted: sylpheed-port's leaf segment rates. Derived independently from the disc and they SURVIVE exactly -- pteff03 +4.0000 then +4.0000 then a hold, pteff03a -4.0667 then -4.0625 then a hold. So their inversion stands: my linearity gate fails on the leaf whose declared track is perfectly straight. And records the third structural consequence of main being stale, which they raised: HANDOFF.md is the delivery contract and it lives on an unmerged branch, so their checkout contains none of this week's entries. Findings written into the contract reach them only through messages -- the channel the protocol says does not count as delivery. Writing it in the contract is necessary and not sufficient when the contract lives where the other party cannot see it.
