The occlusion hypothesis is refuted: build 7 draws the same three ROT strips at higher alpha than English, so there was never an absence to explain. The 0.32-vs-11.9 tension that motivated it was an artefact of my own instrument. Both JP captures were shuttered on the plate pulse, and the plate's pulse is part of the animation -- so the gate synchronises the shutter to the animation's phase. Measured at the shutter instant, the sweep sits 25-26 px apart across two runs in different locales and different sessions: 1.6 % of a ~1600 px traverse. So the 0.32 I recorded as between-session capture noise measures my trigger's repeatability, and I read it as evidence the title is still when it is evidence the gate works. The era adjudication is unaffected -- margin 16.72 clears even the un-locked 11.9 -- and unaffected for the reason that file already gave: correlated noise cancels in a margin. Refutation attempt on sylpheed-port's positional-mechanism rejection: FAILED, the claim stands. Its residual sits inside lit logos, and the logo ROI is byte-identical across five differently-phased frames in two sessions.

# The JAPANESE title (GP_TITLE build 7) at rest -- captured 2026-08-30.
|
|
#
|
|
# Asked for by the port agent: its title_jp row drifted (155/20498 ->
|
|
# 233/61208), localized to a 350x396 block at (405,74) -- the logo stack --
|
|
# and with NO capture of the JP title in the corpus it could say the two
|
|
# renderers had moved apart but not which one moved.
|
|
#
|
|
# MISSION.md has carried this as 'needs one more run' since 2026-08-29.
|
|
# Three earlier attempts failed to reach the interactive title in either
|
|
# locale. The reason is now known and was not the locale: A at the title
|
|
# needs a signed-in profile (title-a-press-fault.md), and no run had one.
|
|
#
|
|
# LOCALE: tools/re-capture/set_console_language.py ja -- canary's own
|
|
# persisted XConfig, offset located from struct landmarks. Restored to en
|
|
# afterwards; verified back at language=1.
|
|
#
|
|
# ✅ INDEPENDENT CONFIRMATION THE LOCALE TOOK: the XMA probe logged a
|
|
# DIFFERENT voice-context set from every English run --
|
|
# ja: 1112064, 1150976, 1177600
|
|
# en: 1294336, 1118208, 1171456
|
|
# The Japanese voice region is a different set of streams, so the switch
|
|
# reached the guest and is not just a menu-language cosmetic.
|
|
#
|
|
# 'AT REST' IS DEMONSTRATED, NOT ASSUMED. Five frames ~1.5 s apart after the
|
|
# plate pulse says the screen has settled:
|
|
#
|
|
# the port's ROI, 350x396 at (405,74) design space:
|
|
# frame 1 vs 0: max |d| 0, pixels differing >8: 0 / 138600
|
|
# frame 2 vs 0: max |d| 0, pixels differing >8: 0 / 138600
|
|
# frame 3 vs 0: max |d| 0, pixels differing >8: 0 / 138600
|
|
# frame 4 vs 0: max |d| 0, pixels differing >8: 0 / 138600
|
|
#
|
|
# the whole frame, as a CONTRAST CONTROL (the plate pulses, so this must
|
|
# move or the instrument is blind):
|
|
# frame 1 vs 0: 39584 px frame 3 vs 0: 71927 px
|
|
# frame 2 vs 0: 58303 px frame 4 vs 0: 69604 px
|
|
#
|
|
# So the logo stack is byte-identical across 6 s while 5-8 % of the frame is
|
|
# moving. The ROI is at rest and the instrument can see motion.
|
|
#
|
|
# WHAT THE CAPTURE SHOWS that the English title does not: the katakana
|
|
# subtitle under the wordmark, and a crystalline burst BEHIND the wordmark --
|
|
# the ptlogo3a/b/c + ptlogo_back2eff* stack, which ui-forced-backdrop and
|
|
# the tie-break work record as TRANSPARENT at rest on the English title.
|
|
# That is exactly the region the port's drift is localized to.

# SECOND, INDEPENDENT CAPTURE -- 2026-08-30, a fresh boot in a separate session.
|
|
# tools/re-capture/jp_title_session.sh (sets ja, captures, ALWAYS restores en).
|
|
#
|
|
# Why: the five frames above demonstrate the logo stack is at rest WITHIN a run.
|
|
# They say nothing about the axis sylpheed-port's drift was on -- BETWEEN runs,
|
|
# where a free-running clock lands somewhere else on a fresh boot. Nothing in
|
|
# this corpus covered that axis, and the ptlogo_eff3 era adjudication rests on
|
|
# a single capture.
|
|
#
|
|
# Within-run stability REPRODUCES in session 2:
|
|
# ROI 350x396 at (405,74): frames 1-4 vs 0, max |d| 0, 0 / 138 600 differing
|
|
# whole frame contrast: 47 278 / 51 034 / 58 922 / 72 958 px moving
|
|
#
|
|
# BETWEEN SESSIONS, inside the 388x423 box the era adjudication uses:
|
|
# 645 of 164 124 px differ, max |d| 41, RMSE 0.3215
|
|
# whole frame, for contrast: 116 492 px differ, max |d| 51
|
|
# -- so the two captures are genuinely from different sessions.
|
|
#
|
|
# THE VERDICT REPRODUCES TO THREE DECIMALS:
|
|
# vs session-1 capture vs session-2 capture
|
|
# stale era rest (108,72) 58.412 58.413
|
|
# fixed era rest (98,42) 41.690 41.692
|
|
# margin 16.722 16.721
|
|
#
|
|
# 📌 And the shape of that is the useful part: capture noise moves BOTH
|
|
# candidates together, so it very nearly cancels in a MARGIN. The absolute
|
|
# scores moved 0.001-0.002 between sessions and the margin moved 0.001, against
|
|
# an in-box capture noise of 0.32. A margin between two renders scored on one
|
|
# capture is far more robust than either score is.

# 🔴 CORRECTION -- 2026-08-30, same day. The BETWEEN-SESSIONS block above rests
|
|
# on a premise I have now measured and it is FALSE.
|
|
#
|
|
# It reasons that a second session probes a new axis, "where a free-running
|
|
# clock lands somewhere else on a fresh boot". It does not. Both captures were
|
|
# shuttered on the plate pulse, and the plate's pulse is PART of the title
|
|
# animation, so the gate synchronises the shutter to the animation's phase.
|
|
#
|
|
# Measured (structures/plate-pulse-phase-lock.md): at the shutter instant, the
|
|
# sweep strips sit 25-26 px apart between two runs in DIFFERENT locales and
|
|
# different sessions -- 1.6 % of a ~1600 px traverse.
|
|
#
|
|
# CONSEQUENCES:
|
|
# * "in-box capture noise of 0.32" is a PHASE-LOCKED LOWER BOUND, not capture
|
|
# noise. At an arbitrary phase the figure is 11.9 (two EN captures a
|
|
# plateau-phase apart). Do not reuse 0.32 as a noise floor.
|
|
# * I read 0.32 as showing the JP title is still. It shows the GATE works.
|
|
#
|
|
# WHAT SURVIVES UNCHANGED:
|
|
# * The margin 16.72 exceeds even the un-locked 11.9, so the era adjudication
|
|
# holds either way -- and holds FOR THE REASON THIS FILE GIVES: noise moves
|
|
# both candidates together and nearly cancels in a margin.
|
|
# * The five-frames-per-run at-rest result, which is not gated per frame and
|
|
# therefore does sample different phases.
