# U3 amendment, 2026-09-27: one submit saves every ask on a verbatim report.
# The operator answered three asks top to bottom, pressed the last button, and
# the 303 reload wiped the first two (`auk-audition`, 15:02:23). Contract:
# docs/contracts/u3_declared_embed_seam.contract.md, "Submitting several asks at
# once" and INV-8. Every row is a change tests/test_embed_browser.py claims to
# forbid. The flight-window rows came from the heid bug-hunt panel on the first
# cut, where every guard of that window survived its mutation.
