# The settle-instant pose's OWN failure mode, censused. 2026-08-30.
# examples/settle_midramp_census.rs
#
# The port agent found ptmsg -- the main menu's footer -- at alpha 127.5 of 255
# at that screen's settle instant, because the longest keyframe-free interval
# ends exactly as the footer arrives. VERIFIED here: build 5's window is
# [44, 56] = 12 units, instant 50, and screen render --settle ALREADY PRINTS
# 'narrow -- this bundle may never settle'.
#
# 'Mid-ramp' = at the settle instant the element sits strictly inside an
# interval whose endpoint poses DIFFER: it is interpolating, not held.

# 🔴 AND THE OBVIOUS READING OF THAT TABLE IS WRONG. 'Narrow window means the
# settle pose is bad' is refuted by the screens that motivated the proposal:
#
#   build  4  title       window 76   wide     port: settle wins 9x
#   build  5  main menu   window 12   narrow   port: settle loses 1.2x
#   build  6  EXTRAS      window 12   narrow   port: confounded
#   build 10  publisher   window  8   NARROWER port: settle wins 75x
#   build 11  developer   window  8   NARROWER port: settle wins 33x
#   build  0  loading     window  4   narrowest
#
# The two splashes have an 8-unit window -- narrower than the main menu's 12 --
# and the settle pose beats rest() there by 75x and 33x. So width does not
# predict quality, and I nearly published that it did.
#
# The predictor is the one the port already stated: the settle pose wins
# DECISIVELY where rest() lands on a transient's PEAK (the splashes: rest()
# returns a=212 / a=255 on flashes that are over by t=45), and loses SLIGHTLY
# where rest() is already sound and an element arrives after the window closes
# (the menus: the footer caught at a=127). Those are independent of width.
#
# 🔴 AND MY OWN FILTER WAS WRONG IN BOTH DIRECTIONS. rest_vs_settle dropped
# bundles with a window under 10 units. That admitted the 10-19 bucket, which
# is the WORST at 45.1 % mid-ramp -- and it EXCLUDED the two splashes at width
# 8, which are the strongest evidence FOR the proposal. A threshold chosen
# from a documented rule of thumb, applied without checking which screens it
# admitted and which it threw away.
