Pin bumped to the TAG formats-pin-2026-08-29 (7eeae30), applying the policy the
previous commit wrote. What I wanted from it: `UiBuild` gained a public
`records` map. Without it a leaf was unreachable through the public API --
parse_build sorted T8aD children into `sprites` and `.rat` children into a
PRIVATE map -- so the focus ring, which lives inside ptbtn0Nf.rat, a record the
parent bundle declares NO element for, could not be located at all. My exporter
was writing 19 of build 5's 21 sprites and I could not see why.
v3 carries two new things.
ROTATION. `rotation_deg`, decoded at keyframe +12, and the game DRAWS it --
confirmed twice by the RE agent on different screens with different elements:
the title's ptloop sweeps declare +30/-45 and a GPU capture submits them at
+30.26/-45.28, and the focus ring ramps 0 -> 360 with everything else constant,
caught mid-spin in a capture. Rotation is about the DECLARED PIVOT, measured.
The comparison renderer does not draw it yet, so a rotation disagreement means
sylpheed-cli is behind, not that the port is wrong. Sign is still an assumption.
THE FOCUS RECORD. A focused button is not a sprite swap: ptbtn0Nf.rat declares
the spinning ring AND the bright label, and since the parent declares no element
for the record, the leaf is the only source of placement for both. v2's single
focus_sprite could not carry the ring at all and drew the highlight 7 px
off-centre by inheriting the base position. That -7,-7 is load-bearing: the f
label is 13 px larger per axis and -7 keeps the two concentric.
Checked against the game, not against the other renderer: rendering main_menu
with OPTIONS focused changes the region x 504..703, y 399..448. The RE agent
measured the same difference in the live capture at x 505..703, y 397..446 --
independently, from the other side. Ring, label and underline all land; the only
visible residual is the ring's spin PHASE, which is exactly the one thing
neither of us has resolved (its second keyframe is untimed, and the screen-level
rule for that is not established to apply inside a leaf). Listed in `unresolved`
rather than invented.
verify-screen is unchanged at 16/16 -- rotation has no effect at rest on these
screens, as predicted.
WHAT I WANTED FROM IT: 56cc7ac, "a RATC child's name is stated, not inferred".
A child was named by scanning backwards for the last printable run of bytes
before its magic. For `pteff05.t32` the three trailing payload bytes are
38 41 58 = `8AX`, which beat the real name, so the child registered under a name
no element declares and resolved to no sprite.
`pteff05.t32` is the full-resolution background of all five menu screens.
Every menu render this port has produced has been missing its background, and
P1 wrote that up as a fact about the disc -- "the bundle carries zero RATC
children for either, so there is no texture on the disc to export". That is
retracted in docs/DECISIONS.md rather than edited away.
The re-export is contained: six new sprites and nothing else. pteff05 on
main_menu/extras and their JP twins, pteff04 on both titles. Each gains a
`sprite` line and moves `layer_source` from "implied" to "sprite" -- the layer
key is now read from the file instead of the decoders' table of keys measured
off the running game, which is the ratchet turning the right way.
pteff05.png is 1280x720; ptbase.png, which had been carrying the background
alone, is 640x360 drawn at 200 %.
Measured against the live capture rather than the other renderer: settled
main_menu RMSE 8.05 % -> 5.92 %. The reference renderer was missing the same
element for the same reason, so no renderer-vs-renderer diff could have found
this -- the third time a capture has caught something both renderers agreed on.
What I wanted from it: `ui_layout::rest()`. At 8b6dbcf a trailing run of
identical keyframes was always treated as the exit, so an element with no exit
animation rested at its invisible pre-roll -- `ptframe1`/`ptframe2`, the main
menu's circuit bracket, which a capture of the running game plainly shows.
Pinned at 5414db3 rather than 4bc9706 where the fix was written, because
5414db3 is where it carries its disc-wide check: 30 of 13 991 elements move, 4
become visible, 0 become invisible. The rule shipped is the RE agent's, not the
condition this port proposed -- mine was too loose and would have erased the
word PAUSE on `pgptitle.rat`, whose trailing run is two identical TRANSPARENT
frames. A trailing run is the hold exactly when it is VISIBLE.
The re-export shows the change was contained: two files differ, and within them
exactly four `rest` blocks -- ptframe1/ptframe2 on both main menus, t=16 alpha
0x00 at the pre-roll position becoming t=62 alpha 0xff at the arrived one.
Every diff line pairs. The other ten screens are byte-identical, no sprite
changed, and `pteff02` correctly did not move.
`loose` exited 126 with "File name too long": the entrypoint ended in
`exec "$@"`, so the whole loop-task.md prompt was handed to exec as a command
and the markdown was tried as a filename.
The launcher was modelled on the RE container's but the entrypoint was written
fresh and simpler, and it left out the half that matters -- the block that turns
a `/loop ...` argument into a Claude Code invocation. Ported it over, with the
two gates that make an unattended run possible: seeding ~/.claude.json so the
first-run wizard does not stop on the theme picker, and claude-autonomous, which
answers the Bypass Permissions disclaimer that has no config key to skip it.
Also mounts the host's Claude credentials, which the container had no way to
reach, and passes SYLPH_AUTONOMOUS=1 from `loose`.
Verified: container stays up, display :97 ready, /reborn mounted read-only,
Remote Control registered, Claude Code started in /work.
