sylpheed-port found three live stale claims in their own source, each already retracted in their log days earlier. Their framing is the one that matters: a correction that does not reach the artifact a consumer reads has not been made, and a comment sits beside the thing it describes. check_refuted.py scanned docs/ only. Running it over tools/ and crates/ for the first time found one here too: jp_title_session.sh justified its own existence with 'a free-running clock lands somewhere else on a fresh boot' -- a claim I refuted myself the day before, when I measured the plate-pulse gate phase-locking the shutter to 1.6 % of the sweep traverse. The script's stated rationale rested on a premise I had already killed. Fixed the file with the correction in place, including what it means for what that script actually measures: a second capture through the same gate is a second sample at nearly the same animation phase, so its RMSE 0.32 is a phase-locked lower bound. Taught the register to scan code behind --code, excluding crates/sylpheed-viewer, which is the human's tool. Controlled three ways: a planted code revival exits 1 with --code, exits 0 without it -- which is the proof the gap was real -- and 0 again once removed.

# Drive a JAPANESE title capture end to end, and ALWAYS put the locale back.
|
|
#
|
|
# The first JP capture (2026-08-30) demonstrated the logo stack is at rest
|
|
# WITHIN a run: five frames ~1.5 s apart, byte-identical over the port's ROI,
|
|
# against a whole-frame contrast control showing 5-8 % of the screen moving.
|
|
# That does not test the axis sylpheed-port's drift was on -- BETWEEN runs. This
|
|
# script exists to take a second, independent capture so that axis can be measured.
|
|
#
|
|
# 🔴 THE ORIGINAL RATIONALE HERE WAS REFUTED, and the retraction never reached this
|
|
# file until 2026-08-31. It read: "BETWEEN runs, where a free-running clock lands
|
|
# somewhere else on a fresh boot". IT DOES NOT. Both captures are shuttered on the
|
|
# plate pulse, and the plate's pulse is part of the title animation, so the gate
|
|
# PHASE-LOCKS the shutter: measured, the sweep sits 25-26 px apart across two runs
|
|
# in different locales and different sessions -- 1.6 % of a ~1600 px traverse.
|
|
# See structures/plate-pulse-phase-lock.md.
|
|
#
|
|
# ⚠️ SO WHAT THIS SCRIPT MEASURES IS NARROWER THAN THE COMMENT CLAIMED. A second
|
|
# capture through the same gate is a second sample at nearly the SAME animation
|
|
# phase, not a sample of a free-running clock. The RMSE 0.32 it produced is a
|
|
# phase-locked lower bound on capture noise, not capture noise. The era
|
|
# adjudication it fed still stands -- its margin, 16.72, clears even the unlocked
|
|
# 11.9 -- but for the reason bgm/jp-title-at-rest.txt gives, not this one.
|
|
#
|
|
# Usage: jp_title_session.sh OUTDIR [wait_s]
