7fef19b3a0 re: the transition between screens is a fade through black, and most of
its timing is on the disc

Q7. Every title-side screen carries a full-screen black .prm quad that
paints last, and its keyframe group IS the transition: black at T0, clear
by T1, clear until T2, then back to black on exit. Read with the corpus's
start-of-a-ramp rule and Q1's time unit that gives 0.87s for EXTRAS,
0.97s for the main menu, 4.08s for the title -- from the file, not from a
stopwatch.

The disc-wide check is per-pak all-or-nothing rather than the 41% the
headline count suggests, and GP_TITLE's 6 of 12 is the useful row: the
six builds carrying a fade quad are exactly the six SCREENS, and the six
without are exactly the six overlays. GP_DIALOG is 0 of 133. That is
independent corroboration of the overlay finding from two iterations ago.

One piece is NOT on the disc and says so: the fade-OUT length. The fourth
keyframe has no time slot, because a group's last block stops four bytes
short. Measured instead, at 30fps, ~0.4s and the same both directions.

And a warning I earned: the luminance rise after a transition is NOT the
quad's ramp. The incoming screen's own elements animate in after the quad
has cleared -- 1.47s observed against a declared 0.97s. Time the fade
from where the frame is pure black.

Rig: screenshot samples at 0.5 Hz and cannot see a 0.4s fade at all,
which is why an earlier burst called this an instant cut. ffmpeg x11grab
at 30fps instead; both go in METHOD.

4e745c8177 re: the title menu wraps -- Q5 measured, Q4 driven, and one of my own
method lines withdrawn

Q5, measured off two boots: up/down move one item and WRAP at both ends
on the 5-item main menu and the 3-item EXTRAS alike; left/right do
nothing; B goes up one level and restores focus to the item you came
from (4/4); B on the main menu returns to the title; B on the title does
nothing. The menu opens on TUTORIAL -- the middle item -- 2/2, though a
third recorded run implies NEW GAME, so that one is reproducible rather
than invariant and says so.

Q4 by driving: LOAD GAME opens the save-slot list, TUTORIAL the lesson
list, OPTIONS the settings menu, EXTRAS build 6, MISSION SELECT the stage
list. NEW GAME is not tested -- A on it hangs the emulator and this
iteration needed the session. The GamePart ID behind each is NOT
measured: it is the entry of the decoded id table whose name matches the
screen I saw, and the page says so rather than wearing the badge.

And the withdrawal. Last iteration I wrote that these menus drop d-pad
presses shorter than ~0.3s. They do not. Once wrap is measured, every
press count I had is exactly right -- four presses moved four steps
THROUGH the bottom, which lands one above where a non-wrapping menu
would. I invented hardware flakiness instead of testing the ends of the
list. METHOD keeps the withdrawal rather than deleting the line.

Also: label brightness is not a cursor oracle here -- the background art
outshines the highlight on some rows. menu_focus.py reads the focus ring
instead, 254 vs <82, no tuning.

88b3ce9af5 re: which GP_TITLE build is which screen, measured against the game
Q2. The archive is eight screens shipped twice, English and Japanese --
not the "build 4 title, 5 main menu, 6/8/9 submenus" the handoff claimed.
Build 8 is the JAPANESE main menu; 6 and 9 are the EN and JP EXTRAS, and
EXTRAS is the only submenu GP_TITLE holds. The PRESS (A) BUTTON plate is
its own build (2/3), composited over the title art and faded in a beat
later, not a state of build 4.

Confirmed by booting to the main menu and walking it: title, PRESS (A),
main menu and EXTRAS each match their render element for element. Builds
0/1 and 10/11 -- a DELTASABER / SYLPHEED A.I. plate -- were looked for in
the whole boot filmstrip, every title-side screen and the attract loop,
and appear in none of them; the reach of that negative is written down
rather than filled in with a guess.

Two rig traps went into METHOD: the menus drop d-pad presses shorter than
~0.3 s, and a grab 2.5 s after a transition can catch a screen mid-fade
-- which nearly wrote "the returned title has no plate" into the corpus.

27e8c51978 re: a keyframe time is worth half a rendered frame, and the ramp is linear
Q1 of the menu port, measured against the running game rather than reasoned
about. The developer-logo splash is the cheap target: it is the first thing the
guest draws and its bundle declares short, unambiguous ramps.

Two results, both frame-exact and both emulator-speed-independent (frame numbers
are VdSwap counts, the guest's own frames):

  * the ramp is LINEAR. A declared 15-unit fade lands on round(255*k/15) for all
    seven of its samples with zero error, k stepping 2,4,6,8,10,12,14. No ease
    can reproduce a constant step of 34 at both ends.
  * the animation clock advances 2.000 time units per submitted frame, over six
    consecutive intervals with no residual, with 1 unit as the quantum
    underneath (one frame in the fade-out advances by 1).

The conversion to seconds is one step further and is flagged as such: 300 frames
took 10.87 s = 27.6 present-frames/second, which reads as a 30 Hz title at 92 %
under the emulator and gives 1 unit = 1/60 s -- the title build 4.2 s, the main
menu build 1.1 s. That reading is not proven, because the rate was measured
while the guest was still streaming from the ISO; the page names the one test
that would settle it and says what changes if it goes the other way.

Committed beside it: the raw draw capture and the per-frame quad CSV, so the
numbers can be re-derived without a disc or an emulator.

e1dcc689bc agent: move the loop prompt's memory into the corpus, and let it push
The autonomous agent's loop prompt had grown to ~9 000 words of accumulated
findings, refutations and traps. That is a symptom, not a style: it was doing
the job the corpus should do, in the one place that dies with the container.
Three concrete failures followed from it, and each gets a structural fix rather
than a louder instruction.

1. IT REPEATED WORK IT HAD ALREADY DONE.
   The "do not revive" list and the method traps existed ONLY in the prompt, so
   nothing pointed a fresh iteration at them. Extracted verbatim into two
   tracked files:

     docs/re/REFUTED.md  105 claims tested and dead, grouped by subject so a
                         grep for your noun finds the neighbourhood
     docs/re/METHOD.md   the traps already paid for -- controls, inference,
                         searching, reading data, runtime

   Both are linked from INDEX.md, and the loop prompt now opens by requiring
   them to be read. This is the fix for "re-derived something already known":
   the knowledge is now where the next iteration looks, not in a context window.

2. IT FORGOT TO ARM THE NEXT WAKEUP.
   The prompt tried to solve this by shouting at itself in the first line. The
   real fix is to stop asking: `loose` now defaults to a FIXED interval (45m),
   so the harness owns the cadence and a forgotten ScheduleWakeup cannot end the
   run. SYLPH_LOOP_INTERVAL= (empty) restores self-pacing.

3. IT COULD NOT PUBLISH, SO THE WORK ONLY EXISTED IN THE CONTAINER.
   New `push-work`, plus a read-only credentials mount
   (SYLPH_GIT_CREDENTIALS, default ~/.sylph-git-credentials). It pushes the
   CURRENT branch only, refuses anything that is not auto/*, and never
   force-pushes -- so the consolidated line stays a human's decision and a
   confused iteration cannot rewrite history. The loop prompt now requires a
   push on every iteration that commits, rather than at the end of some longer
   arc, which is exactly when a container dies.

The prompt itself drops from ~9 000 words to 85 lines and, more importantly,
stops accumulating: findings go in the corpus, and the prompt points at it.
