b632602517 docs: P3 -- the boot runs unattended, and four answers taken as given
Gate: `godot --path port -- --boot --film=/tmp/boot` runs publisher_logo ->
developer_logos (4.65 s) -> title (8.57 s), holding on the title after 13.05 s,
each screen fading in, holding, and fading through black into the next.

verify-screen now covers all 16 screens and passes `--all` to the reference
renderer: the exporter addresses by pak entry index, which is the numbering
`--all` uses, and without it `--build 10` would land on entry 12. The four new
splash bundles come in at max 1-2/255. The three known differences are unchanged.

Also recorded, taken from the RE agent rather than re-derived:

* Focus stays "replace" -- over-vs-instead is unobservable (the focused sprite
  covers the base at 100 % of base-visible pixels; the two compositions differ by
  RMSE 1.1, under the gamma floor). The port guessed right for the wrong reason.
  The real gap is that ptbtn0Nf.rat declares TWO sprites -- a glowing ring, then
  the label -- where ptbtn0N.rat declares one. P5's, and the ring's placement is
  not decoded, so it will be authored from the capture and marked as such.
* RMSE against captures has a FLOOR: capture ~ 255*(render/255)^g, g ~ 1.49 menu
  and EXTRAS, 1.34 title, and it is a ramp the GAME installed, not a capture-path
  artefact to subtract. Narrow reach (fitted on mostly-dark patches), so the port
  will not extrapolate it and will not apply it to rendered output. It is a
  comparison constant, not a rendering one.
* Rotation is escalated to a human and the port has NOT acted. The RE half is
  answered -- about the declared pivot, measured -- and it has zero effect on the
  five screens at rest.

0a026074d3 port: play the exit ramp, and run the boot sequence unattended
P3. The exit is the group playing ITSELF out, not a black rect over a frozen
screen -- and that was settled by a test that discriminates rather than by
plausibility. Under the black-rect model every region is scaled by the same
1-alpha, so the button/background brightness RATIO would hold constant through
the fade; measured, it falls 6.495 -> 5.574 -> 3.105 -> 2.125 -> 1.935.

Implemented by giving the final untimed keyframe a SYNTHETIC time,
exit_ramp_units after the last timed one, then interpolating it like any other
frame. One code path: arriving and leaving differ only in how far `t` is allowed
to run, not in kind. `holding` is what the sequencer clears to send a screen away.

The sequencer waits on nothing the disc does not carry. A screen holds until its
own group has arrived, then plays out; `dwell` in flow.json is deliberately empty
because each screen's dwell IS its keyframe group (publisher wordmark 3.92 s,
developer logos 3.17 s, both read from the disc). Any extra hold would be a
number nobody measured.

The last screen keeps holding -- nothing is taking the title's place, and a boot
that ends by fading to black looks like a boot that crashed.

flow.json reproduces an OBSERVATION and says so in its header: Q6 closed with a
negative, the order is on the disc nowhere, a transition is a call with a name
argument chosen by code. The intro video's place in the real boot is named as a
gap rather than the order being quietly rewritten to hide it.

0d2bf1f241 export: reach the splash by authored entry index, and key names by entry
There were TWO splash screens and this port had neither. Entries 11/14 are the
developer logos; entries 10/13 are the SQUARE ENIX publisher wordmark, the first
thing the boot shows, which nothing in this project had noticed.

They have no .rat layout child so `is_build` cannot see them, and the RE agent
established that no CONTENT rule can either: design size fails (every extra
composable bundle sampled is 1280x720, same as every screen) and element count
fails (fragments run 2..15 elements in GP_OPTIONS/GP_SAVE_LOAD, the splash
halves are 3 and 7 -- the ranges overlap).

So `screen_builds` is `is_build` plus an authored allow-list of ENTRY INDICES,
each carrying a `why` that says it is a locator and not a claim. An allow-list
rather than a loosened predicate because this is safe in GP_TITLE and would not
be in general: there, widening adds exactly four bundles and all four are real
screens, zero fragments.

screen_names.json is rekeyed from enumeration ordinal to pak entry. Widening
renumbers ordinals, and a name that moves when the enumeration rule changes is
not a name -- the file always called the entry the stronger locator, and it is
now the only stable one. The two unnamed plates therefore renamed build_10/11 ->
build_12/15; they were always locators, and now they locate the right thing.

All 16 export and validate.

3588a0270d docs: record what the port needs from the RE agent, ranked by cost to the port
Five items, written down here rather than only in a message, because a request
that lives in one conversation dies with the container. Two are blocking P3 (how
to recognise the splash bundle, and what the ~0.4 s fade-out actually measures),
one is cheap and prevents P5 rework (focus drawn over vs instead of the base --
the port picked replace without evidence, and the oracle says it picked wrong),
one needs a joint decision rather than a unilateral one (whether the port should
draw the newly-decoded rotation and thereby become deliberately more correct than
the renderer it verifies against), and one calibrates whether RMSE against
captures has a floor at all.

f6fccee11c deps: bump the pin to f817dd5 -- the menu screens get their background
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.

40aee1da48 docs: answer the RE agent's question, and record the stale-reference failure
Their question was which screens the other four of "six" elements are on. The
six span the whole 12-screen export: ptframe1/ptframe2 on main_menu and
main_menu_jp (trailing run alpha 0xff, VISIBLE -- their rule accepts these, and
they are the four it revealed disc-wide), and pteff02 on title and title_jp
(trailing run alpha 0x00, TRANSPARENT -- their rule excludes it).

That exclusion is correct, and their own measurement is what proves it: pteff02
is the 25 % dim quad, and they measured the title render going from +13.14 to
+0.55 against the plate-free capture once it is drawn. So `rest` must stay at
0x40 and must not move to the transparent trailing run -- which is what their
alpha rule does. Two investigations converging from opposite directions, and no
third discriminator is needed.

Also recorded: the reference renderer was stale for three diff runs and reported
success throughout, and the shape worth naming is that a build system reporting
success is not evidence the artifact you are about to trust is the code you
pinned. The RE agent hit the same class of trap this session from the other side.

BLOCKED.md: the loop/hold question is answered (groups hold -- ptloop01/ptloop02
park off-screen at x=1521 and x=-839), and the rest_plateau entry is closed as
fixed, noting the adopted rule is theirs and not the looser one this port
proposed.

b36dddaeb5 build: key the reference CLI's target dir by the pinned revision
The reference renderer was a revision behind for three consecutive diff runs and
nothing said so.

After the pin bump, `build-reference-cli` reported success at rev 5414db3 and
`verify-screen` showed main_menu jumping 3/255 -> 72/255. The natural reading was
that the port had regressed. It had not: the port was right and the REFERENCE was
stale. The shared CARGO_TARGET_DIR still held a `sylpheed-cli` built from
8b6dbcf, cargo said "Finished in 0.13s" and left it there. A clean target dir
built a binary resolving ptframe1 to (440,108) t=62; the shared one still said
(620,108) t=16.

The old check -- does `screen list` run -- cannot catch this. A stale binary runs
perfectly.

So: build into `$CARGO_TARGET_DIR/reference-cli/$rev`, keyed by the pin, where a
new revision has no artifacts to reuse. Then verify the binary AGAINST export/:
both come from the same pin, so if the CLI resolves ptframe1's rest differently
from what the exporter wrote, the two halves of the verification are not the same
revision and it fails loudly. It compares the two rather than asserting a
literal, so it stays true when the pin moves again.

docker/bin is baked into the image, so this needs an image rebuild to reach
PATH; until then invoke the repo copy by path.

22d7c88cf5 port: settle at the hold, not at the last timed keyframe
P2 shipped the wrong rule and the title is the counter-example. I had reasoned
that the exit is the final untimed keyframe, so anything timed was still the
entry. It is not: `pteff02` on the title holds at t=46 with the 25 % dim quad at
alpha 0x40 and then ramps to 0x00 by t=236. The exit can be a long run of TIMED
keyframes, and running to the end drops the dim and leaves the whole screen
~13/255 too bright -- exactly the luminance excess P2 recorded (oracle 64.1,
rest 62.8, timeline 80.0) and filed as an unexplained "glow slab".

A group is pre-roll -> ramp in -> hold -> ramp out -> post-roll, and a screen
that has arrived sits on the hold. `settle_units()` is now `rest.t`, the
decoders' own identification of that hold.

The check is that a disagreement vanishes: on ALL TWELVE screens the settled
timeline is now byte-identical to the `--pose=rest` render, where before this
four differed by up to 247/255. The timeline's endpoint should BE `rest` -- the
animation is what it adds, not a different destination -- so this is the
property to want, and it holds with no special case.

Credit where due: this came out of the RE agent measuring the title's dim quad
against a plate-free capture, in pursuit of a different question.

9ecef5208e deps: bump the sylpheed-formats pin 8b6dbcf -> 5414db3 for the rest() fix
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.

89de93b18f docs: the timeline lands on rest -- except on six elements, where the game
agrees with the timeline

P2's gate is the buttons sliding in, and `tools/screen-strip` renders the strip
that shows it. But the useful result came out of checking where the animation
settles.

On 8 of 12 screens the settled timeline is BYTE-IDENTICAL to the declared `rest`
pose -- the port walks the keyframes with an authored time unit and arrives, to
the pixel, where the pinned decoders independently say the screen rests. On
`main_menu` the two differ in exactly one region, 400x470 at (440,108): the
bounding box of `ptframe1` and `ptframe2` and nothing else.

`rest` puts both at their first keyframe, off-position and transparent. The
capture of the running game shows them -- the bright circuit bracket around the
menu. Cropping the same region from the capture and from both renders puts the
ring and its elbow trace in the timeline render pixel-aligned with the game's,
and absent from the rest render. Geometry, so it does not depend on the
capture's gamma or on its having been taken with NEW GAME focused.

`ui_layout::rest_plateau` excludes a trailing run of identical keyframes because
it is normally the exit. On an element with NO exit animation the trailing run IS
the hold. The condition that identifies these exactly, with no false positives
here, is "the final untimed keyframe has the same pose as the last timed one" --
six elements, and `rest()` misses all six. Filed in BLOCKED.md for the RE agent:
the decoders are pinned and are not this port's to fix, and `sylpheed-cli screen
render` is missing the bracket too.

Worth saying plainly what this does to P1: the port and the reference agreed on
`main_menu` to 3/255 and BOTH were missing two elements the game draws. Two
renderers reading one field through one decoder agreeing is not evidence the
field is right. BLOCKED.md had already said that about the pivot; here it bit.

The title is NOT settled and P2 does not claim it. `rest` and the timeline
disagree there by 142-247/255, the only live title capture composites the PRESS A
plate over build 4 so it cannot be diffed against the title alone, and both of
the port's modes draw a cyan glow slab the game does not have -- a third problem,
P3's. Recorded as an open question rather than resolved by tuning.

Also reconciled against the RE agent's new work: Q8 is answered -- the SE waves
are located in `Static.slb` (move/confirm/back), which unblocks P6's audio; and
the title's transitions are a lookup by NAME, giving P3/P5 the game's own screen
vocabulary as candidate `goto` targets, marked as the name match it is.

0db45b4c66 port: play the keyframe timeline, with the time unit authored in one place
P2. A keyframe is the start of a linear ramp toward the next; `ScreenView` walks
them at `time_units` and `boot.gd` advances that in real time, or freezes it with
`--time=<seconds>`.

`authored/timing.json` holds the ONE constant this needs. HANDOFF Q1 is answered
-- linear, 2 units per rendered frame, 1 unit = 1/60 s -- but that conversion was
MEASURED off the running game, not read from a file, so it is authored rather
than exported and it says so at length. Expressed as units-per-second, because
60 is exact and 0.01666... is a decimal a reader has to recognise.

The timeline stops at the last TIMED keyframe and never plays the exit. Every
group's final keyframe carries no `t` -- across this export it is a fade-out for
116 of 134 elements, a scale-and-slide exit for 12, and identical for 6 -- so
playing into it would mean inventing how long the ramp takes. That duration is
the screen transition, it is measured at ~0.4 s, and it is P3's to author with
its own evidence. `exit_ramp_seconds` is therefore null on purpose, not missing.

`--pose=rest` keeps the P1 behaviour available: since the port's default is now
the timeline and the two DISAGREE, renderer-vs-renderer diffing has to be able to
ask for the same assumption the reference renderer makes.

The interpolation is checked by where it lands: on 8 of the 12 screens the
settled timeline is byte-identical to the rest render.

146a604500 docs: the P1 diff, and the one question it raised
`main_menu` -- the milestone's gate -- agrees with the reference renderer to
within 3/255 on every channel of every pixel, RMSE 0.38 %, no pixel above 4 %.
Nine of the twelve screens are at or under that; two are byte-identical.

Three exceed it, and each gets a cause rather than a wider tolerance:

* `title` (max 6): every disagreement is INSIDE A TIE -- the derived order and
  the CLI's measured-off-the-game order differ only among elements with
  identical layer keys. That is exactly the residual HANDOFF Q3 documents and
  the export already declares in `unresolved: paint_order_ties`. Cost: 904 px at
  4-6/255 in one glow band. The port keeps the stable sort; fitting it to one
  screen's capture would be tuning.

* `title_jp` (max 154): `ptlogo_eff2` at 125 % is the only drawn element in the
  whole export at a scale that is not a whole multiple of 100 %, and `title_jp`
  is the only screen over 6/255. Same fact twice. `ui_layout::blit` samples the
  source at the destination pixel's top-left corner; a GPU samples at its
  centre, and at 125 % those disagree on one column in five.

  I think the CLI is the one that is wrong -- corner-sampled nearest is a
  half-pixel bias toward the top-left that no rasteriser produces. But that is a
  reading, not a measurement: it needs a framebuffer capture of the Japanese
  title screen, so it is filed in BLOCKED.md as a question. The port is NOT
  changing to match, because matching would mean reproducing a half-pixel offset
  on purpose to make a number smaller.

* `extras` (max 4): two pixels.

Also reconciled: the pivot question predicted a P1 diff could not distinguish
the declared pivot from half the texture, because both renderers use the
declared one. That held. Recorded so the agreement is not later mistaken for
evidence -- and P2 will not settle it either.

BLOCKED.md's `/reborn` HEAD updated to bc6354d, with a note that the mount is
read-only by design and `git -C /reborn pull` fails rather than being skipped.

a79acdd29a tools: verify-screen -- diff every exported screen against the reference renderer
The P1 gate is a pixel comparison, so it needs to be a command rather than a
paragraph. `tools/verify-screen` renders each screen in the manifest both ways
and reports the largest per-channel difference anywhere in the frame.

Both renderers are held to the same inputs on purpose:

* the reference CLI is the one `build-reference-cli` builds from the revision
  the exporter is PINNED to -- not `/reborn/target/`, which is a live mount of
  the other agent's checkout and moves mid-iteration. A pixel disagreement
  against a moving decoder has a free variable in it and proves nothing.
* `--black`, because the screen carries its own background and the CLI's default
  dim slate stands in for a 3D scene that is not on this screen.
* `--primitives --animated`, because the port draws every element at rest and
  those two flags are what make the CLI draw the same set. NOT `--focus`:
  nothing is focused at rest.

The threshold is 3/255 -- what integer-truncating compositing in the CLI and
float rounding on a GPU differ by. Above that is a placement, order or colour
disagreement that needs a reason, and the script says DIFFERS rather than
pretending a wider tolerance is a result.

3d12498550 port: Godot draws an exported screen at its resting pose
P1. The project reads only `export/` -- the manifest, a screen's JSON and its
PNGs -- and draws every element at `rest`, in the export's own `paint_order`.

Three choices worth the words:

* `ExportTree` addresses screens by manifest NAME, never by path, and checks
  `format` on the manifest and on each screen before drawing. Textures are
  decoded from bytes at runtime rather than Godot-imported: `export/` is
  gitignored and regenerated wholesale, and a `.import` per sprite would be
  derived state next to derived state, invalidated on every re-export.

* One CanvasItem draws the whole screen. `paint_order` is already back-to-front,
  so honouring it is a loop; spreading it across sixteen nodes' z-indices would
  hide the one unresolved thing about that order -- the ties -- behind Godot's
  sibling rules.

* The screen renders into a SubViewport sized to the export's `design` rect.
  Capturing the window instead gave 1280x720 of screen minus a window manager's
  title bar: 1235x695. A gate that rescales that to compare against a 1280x720
  composite is measuring the compositor.

Nearest-neighbour filtering, because the export is a 1:1 copy of the disc's
texels, elements draw at up to 500 %, and it is what `ui_layout::blit` does --
so a filter difference cannot masquerade as a placement difference in the diff.

No keyframe interpolation and no focus state: both depend on constants that are
MEASURED rather than decoded (HANDOFF Q1, Q5), and a pixel-diff gate must not
have one of those inside it. P2 and P5.

fa74d69886 port: push-work must not configure the repository it runs in
It set `git config --local credential.helper "store --file=$HOME/..."`, which
PERSISTS in the repository. The repo is a bind mount the host also uses, so the
host's git inherited `store --file=/sylph-home/port/.git-credentials` -- a path
that exists only inside the container -- and every host push then failed with
`unable to get credential storage lock: No such file or directory`.

Same root as the EBUSY credential error, from the other side: a tool that
configures a shared repository to suit itself breaks every other user of that
repository. Now applied with `-c` to the single push invocation.

Cleared the leaked setting from both checkouts by hand. Syplheed-Reborn had it
too, from the RE container's copy of this script.

0fccea389d port: fix the credential mount, the /reborn pull, and cargo re-fetching
Three fixes from the port agent's first infrastructure report.

**A. The credential file is written, so it cannot be a read-only mount.**
`credential.helper=store` rewrites its file after a successful auth: temp file,
then rename over the target. Renaming onto a bind-mount point gives EBUSY, which
surfaces as `fatal: unable to write credential store: Device or resource busy`.

The push succeeds anyway, and that is the real hazard -- a `fatal:` line that is
routinely wrong teaches the reader to ignore the one that is real. It also fired
intermittently, so it read as flakiness rather than as a mount.

Fixed by mirroring the pattern already used for .claude.json: mount it as
`.git-credentials.host:ro` and have the entrypoint copy it to a writable
~/.git-credentials at 600. Mounting rw would also silence it, but then the
container can clobber the host's real credential file; copying cannot.

**B. `git -C /reborn pull` can never work, and should not.** /reborn is a live
read-only mount of the RE agent's working tree -- it updates itself, and pulling
would move another agent's checkout. The prompt now says so, and adds the
consequence the agent found the hard way: because the mount is live, HANDOFF can
move mid-iteration, so anything copied out of it (BLOCKED.md especially) may
already be stale and must be re-checked rather than trusted.

**C.** CARGO_HOME moves to a named volume; it was on the container overlay, so
the pinned decoder source was re-fetched from the network on every fresh start.

Also adds SYLPH_PORT_REPO, so this launcher can be run from a worktree without
repointing the agent's checkout -- which is how these edits were made, the agent
being mid-iteration on auto/p0-exporter in the shared tree.

a1d0e8e2c3 merge P0: the exporter, FORMAT v2, and the container script fixes
The port agent's first published arc. Merged from auto/p0-exporter so the image
build below carries its docker/bin fixes -- build-export follows the exporter's
new subcommand shape, and build-reference-cli makes the pinned reference CLI
reproducible rather than a hand-built artifact in a volume.

5d04ef16fe docker: fix build-export for the subcommand, and build the reference CLI at the pin
Two tooling fixes, both needed before P1 can diff anything.

`build-export` was calling `sylpheed-export --disc ... --out export`, which P0
broke when it moved the exporter behind `export` / `check` subcommands. It is a
regression from 8dd0577 and this is the fix. It now also runs `check` after
exporting, because `export` writes a tree and `check` is the only thing that
says the tree is readable by something other than the program that wrote it.

`build-reference-cli` is new. `sylpheed-cli screen render` is the reference the
Godot port gets diffed against, and the only copy of it in the container is
/reborn/target/release, which has two problems: the release binary predates the
`screen` subcommand entirely, and /reborn is a LIVE mount of the other agent's
working tree -- it moved from e81dcad to f5e7426 during a single iteration. A
reference renderer that runs different decoders than the exporter puts a free
variable in every pixel diff, so this builds the CLI from the same pinned
revision the exporter uses and drops it on the persistent target volume.

Both are COPY'd into the image at Dockerfile:76, so neither takes effect in a
running container until the image is rebuilt. The reference CLI is already built
into the target volume by hand, so P1 is not blocked in the meantime.

order moves from `unresolved` into the export, because Q3 decoded it — a u16
layer key at +0x0A, stable-sorted — and a decoded answer is read in the
exporter. `paint_order_ties` replaces it, because the tie-break is still
unknown.

Where a layer key is not in the file it comes from the decoders' table of keys
measured off the running game. That is a different kind of fact, so it is
labelled: `layer_source` is "sprite", "implied" or "none".

BLOCKED is reconciled against HANDOFF at /reborn e81dcad. Seven of its ten rows
are answered and are moved out; what remains is Q8 (no cue-to-event binding),
the two Q10 unknowns (which BGM, and where a loop restarts), Q9's unsettled
skippability, Q4's untested NEW GAME, and Q6's undecoded boot driver.

It also raises one question back, found by counting the export rather than by
reverse engineering anything: the decoders document a .t32 element's pivot as
"exactly half the decoded texture's dimensions (verified 7/7 on the tutorial
bundle)", and on GP_TITLE that holds for 55 of 93 sprite-bearing .t32 elements.
38 do not, some grossly — ptlogo_back2 is 1118x262 with pivot (500,117) where
half is (559,131). It changes nothing today, because the exporter emits the
declared pivot and the pivot only matters when scale != 100%. But scale IS
animated here — 177 keyframes across GP_TITLE are not 100%, including on the
title screen P1 has to draw — so the question of what the running game anchors a
scale to is worth an answer before P2. Noted there that the port and
`sylpheed-cli screen render` make the same choice, so a P1 diff cannot
distinguish them and their agreement is not evidence.

Sylpheed port agent
8dd0577e01 export: P0 — GP_TITLE's screens and sprites into the open tree
`sylpheed-export export` reads `dat/GP_TITLE.pak`, enumerates its twelve screen
builds, and writes each as one `sylpheed.screen/2` document with its sprite PNGs
beside it. `sylpheed-export check` validates that tree against docs/FORMAT.md
with no disc in hand — the P0 gate is "validates against FORMAT.md", which is
not something anyone can confirm by reading, so it is a program.

Two readings from FORMAT v1 turned out to be wrong and are corrected here rather
than carried:

* The focus sprite does NOT come from the element's `opt ` link. That was
  measured and refuted upstream, and this export shows why plainly: on the main
  menu `opt ` chains ptloop01 -> ptloop02 -> ptbtn01, two decorations and then a
  button. The highlight pairs by sprite NAME instead (ptbtn01.t32 <->
  ptbtn01f.t32), which is the convention HANDOFF blesses and which resolves all
  five main-menu buttons. The raw link is still exported, renamed `opt_link` so
  nothing downstream mistakes it for navigation.
* There are TWO modulate colours in different byte orders, and they multiply.
  v1's single `#rrggbbaa` could not carry both and silently dropped the alpha
  that every fade ramps. They are now `tint_rgba` and `fade_argb`, with the byte
  order in the key name, because getting it backwards is silent and reads as an
  art bug rather than a parse bug.

The exporter takes exactly one authored input: `authored/screen_names.json`,
because the disc does not name its builds and "build 5 is the main menu" is a
measurement (HANDOFF Q2), not a field. Every name it applies is stamped
`name_source: "authored"` with the evidence in `name_why`, and `check` rejects
an authored name that has no `why` — so the derived tree stays honest about
which of its fields is a decision.

Sprites are per screen, not a flat pool: `main_menu` and `extras` both ship a
`ptbase.t32` and they are different pictures.

Checked, not assumed:

* two exports of the same disc are byte-identical;
* five mutations of a valid main_menu.json — a broken paint_order permutation,
  a dangling focus_sprite, a reversed buttons list, a `#rrggbbaa` colour and an
  invented name_source — are each caught with a specific message.

`t` stays raw. Q1 is answered, but the seconds conversion is measured off the
running game and its own finding flags the frame-rate measurement as the part
worth re-testing; if the game presents at 60 Hz every duration halves. One
constant, at P2, in a file that says it is a decision.

b07381d443 port: read the session link from the container log, not the transcript
`sylph-port remote` never returned. Two bugs, one behind the other.

The glob `/sylph-home/port/.claude/**/*.jsonl` ran under `sh`, which has no
globstar, so it stayed literal and matched nothing -- the lookup could not have
succeeded however long it waited.

Fixing that exposed the real problem: the session transcript records every
command run inside the container, including this lookup, so grepping it matched
our own pattern string back and returned a truncated URL. The container log is
the right source and has no such feedback loop.

58c6d3874c port: fix the container exiting instead of starting the agent
`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.

d475e78d80 port: pin Godot 4.7.2, and decide the MCP/skills question
The pin was 4.3, chosen without checking; 4.7.2 is the current stable (released
2026-08-18). Getting this right matters more here than usual because the project
diffs Godot screenshots against a reference renderer, so the engine version is
part of the measurement.

No Godot MCP server. Not because they are bad -- the mature ones need a LIVE
editor plus a WebSocket plugin and a Python server, which is a daemon, an editor
process and a second runtime added to an unattended loop. And their headline
feature, scene-tree introspection and node manipulation, is built for someone
hand-authoring scenes in the editor. This port GENERATES screens from exported
JSON: the agent writes a loader, not a scene tree, so the feature that justifies
the complexity does not apply. What it actually needs to verify itself -- run
headless, screenshot, diff against sylpheed-cli screen render -- is already a
bash job.

Third-party skill packs are the opposite trade: pure context, no runtime. Worth
revisiting, deliberately not installed now, because a skill is instructions
injected into an agent running with approvals disabled -- a supply-chain
decision, not a default -- and because P0/P1 need no advanced GDScript. The
agent may propose one, naming the milestone it unblocks, for a human to vendor
and review.

9d96be609e scaffold the Godot port, as its own repo with its own agent
The port is deliberately separate from the reverse-engineering project: its own
repository, its own clone, its own container. Two writers in one working tree
means files change under whoever is mid-edit and a `git add -A` by one sweeps up
the other's work -- which happened today in the Reborn tree, so this is set up
not to repeat it.

The wall: Godot never reads a disc format. An offline Rust exporter converts the
user's disc into JSON + PNG + Ogg, and the Godot project reads only that. No
GDExtension, no Rust in port/. Beyond the practical reason -- Godot cannot read
IPFB, RATC, T8aD, XMA or WMV -- there is the design one: modding is a goal, and
if the runtime reads the original formats then modding means reverse
engineering, whereas if it reads JSON it means opening a file.

The decoders come from sylpheed-formats PINNED BY REVISION (8b6dbcf), not
vendored and not reimplemented. `sylpheed_formats::media` in particular already
owns every case where one playable thing is not one archive entry: entries that
span segment files, banks with several sub-waves, and the cutscene voices, which
are one continuous XMA stream chunked into VOICE_*.slb entries whose boundaries
do NOT match the cues. That last one is the easiest thing in this project to get
subtly wrong, so the mission says outright not to re-derive it.

docs/MISSION.md is the objective (P0-P7, each gated by an artifact rather than
by compiling). docs/BLOCKED.md lists what cannot proceed until the RE agent
answers Q1-Q10, and says plainly that none of it may be guessed -- this agent
has no emulator and no oracle, so a value it invents is indistinguishable from a
decoded one a month later.

The container is deliberately small: 3 cpus / 4 GB against the RE container's
6 / 7, and an image with no C++ toolchain, no Vulkan stack and no emulator. Two
full-size containers do not fit on this box beside a desktop.

Its launcher sets the git identity through GIT_AUTHOR_*/GIT_COMMITTER_* rather
than writing [user] into .git/config -- the config route captures every commit
made in that tree, including a human's, which is how six of today's commits
ended up attributed to the RE agent.
