`slb_leading_segment_disc` was SIGKILLed by the OOM killer in `docker/ci/run`
at its 7 GB cap, so the documented 45/377 baseline did not reproduce on a 15 GB
box.
`PakArchive` holds the whole concatenated payload in memory and `sound.pak` is
1.01 GB (sound.p00-.p04). `bank()` and `bank_named()` opened it on every call --
inside loops -- and five tests opened their own besides, ~26 opens in all. With
cargo's default thread count that is ~6.1 GB of archive in flight against a
7 GB cap with `--memory-swap` equal to `--memory`, so there is no swap to
absorb it.
The archive is immutable once open and every accessor takes `&self`, so one
`OnceLock` instance is equivalent to N private ones at 1/N the memory.
⚠️ The failure mode is worth knowing: a SIGKILLed suite prints no
`test result:` line at all, so it disappears from a scraped tally instead of
failing visibly. The run still reported "0 failed" -- true, and useless. Check
cargo's exit code (101), not the tally.
Measured in the capped container, 7 GB, default threads:
* before: SIGKILL (signal 9), 0 of 10 tests reported
* after : 10 passed in 3.17s
* (single-threaded before the fix: 10 passed in 22.64s -- the fix is also
~7x faster, because it no longer re-reads 1 GB from disc 26 times)
* cargo fmt --check clean; cargo clippy --tests -D warnings clean

Finishes #16 in the three places its earlier remedies missed.
`tests/`: the last four local `disc_root()` copies now use `tests/common`, and
with them goes the one real hardcoded fallback — `ui_keyframe_record_disc.rs`
fell back to an absolute path on one machine, which made `unset SYLPHEED_DISC`
a no-op there. Control: with the corpus absent that suite now finishes in 0.00s
instead of 57.55s, so it skips rather than finding a disc of its own.
`examples/`: seventeen examples defaulted to `/disc`, the mount point inside the
CI container. Redundant there — `docker/ci/run` sets `SYLPHEED_DISC=/disc` — and
wrong everywhere else, where a missing corpus turned into a file-not-found
against a path that has never existed on the host. They now name the variable to
set, like the other hundred examples already did.
`docker/ci/run`: mount `$SYLPHEED_RES3D` and `$SYLPHEED_ISO` alongside the disc.
Only the disc was mounted, so an in-container run sat out the res3d and iso
suites while looking like a full one — the defect this issue is about, in the
runner itself.
Measured in the container on this desktop with all three corpora present:
45 suites / 377 passed / 0 failed / 14 ignored, and `sylpheed-corpus-report.txt`
now reports PRESENT for all three rather than for the disc alone.

Instructions and generated text that still sent readers to `xenia-rs`, which is
archived and deleted locally. Provenance and dated research records are left as
they are — "lifted from xenia-rs", or a finding stating what database it was
measured against, is still true, and rewriting it would falsify the record.
Changed, because each one tells someone what to do today or writes stale text:
docs/re/README.md the RE toolchain guide queried `xenia-rs/sylpheed.db`
with `xenia-rs/zq.py`, and its "Dynamic" bullet said
to prefer xenia-rs's probe suite OVER Canary. Now:
`sylpheed.db` at the repo root (how to build it and
re-stamp names), `tools/zq.py`, dynamic = Canary, and
`.rdata` reads from the `.pe` (offset = VA - 0x82000000)
in place of `--dump-addr`.
challenge-mission-gate.md, structures/achievements.md
reproduction commands `python3 xenia-rs/zq.py dis …`
crates/sylpheed-xexdb/SCHEMA.md
titled after the retired `xenia-analysis` crate,
citing `xenia-rs dis`, pointing at a `xenia-analysis`
source path
sylpheed-xexdb/src/formatter.rs
WROTE "generated by xenia-rs" into every disassembly
it produced (no test pins the banner)
sylph-xexdb.rs, db.rs "SQLite" / "DuckDB writer for xenia-rs"
sylpheed-formats/src/hash.rs
pointed at `xenia-rs/RE_SYMBOLS.md`, now at
`docs/re/RE_SYMBOLS.md`
Verified: every rewritten reproduction command was extracted from the doc and
run as written against the regenerated database — all 5 exit 0 and return the
disassembly they describe. The README's function count (25 676) is the database's
own. `cargo fmt --all -- --check` clean.
Not changed, deliberately: the README's Oracle bullet says Canary's native Linux
ELF "crashes / does not run". That is about Canary, not xenia-rs, and it conflicts
with a July note that the native build works — unverified either way here.

`the_derived_order_puts_primitives_last_and_that_wipes_screens` asserted that
switching primitives on still flattened at least one screen (`wiped_on > 0`),
and said to turn `include_primitives` on by default the day it stopped.
`cfcda55` made that day arrive — a keyless primitive that would hide the screen
is now forced to paint first — and the wire had been red since 2026-08-29,
invisible to CI because the runner has no corpus and the suite self-skips.
#38 chose option A: keep the default off, and pin the fix instead. The flatness
proxy stood in for "paint order is solved", and the fix's own record says that
is only partly true — "This does **not** make `include_primitives` safe by
default" (docs/re/structures/ui-prm-primitives.md). So:
* renamed to `no_build_is_wiped_with_primitives_on` — the old name asserted
the bug; it survives in the doc comment for anyone searching from #38;
* `wiped_on > 0` -> `assert_eq!(wiped_on, 0)`, with a message saying what a
failure now means (`forced_backdrop` regressed) and that it must not be
"fixed" by turning primitives off in the test;
* `include_primitives` stays `false`; no library code changes.
It is the only end-to-end check of the rule: the four tests in
`ui_forced_backdrop_disc.rs` pin its mechanics, and none composes with
primitives on.
Verified with the corpus present, including that it can fail:
fix 3 passed 125 builds draw a primitive, 0 wiped
forced_backdrop disabled FAILED 36 of 125 wiped — the new message fired
restored 3 passed 125 builds, 0 wiped
The control's 36 is exactly the "36 builds ... wiped by our own sort" that
`cfcda55` and `ui-forced-backdrop.md` report — the guard independently
reproduces the fix's own number, so it measures precisely what was repaired.
The control was a one-line `return false;` in a scratch copy; the working tree
was restored and `git diff` showed only this test file before committing.

`mesh_consistency_disc.rs` had the only conflict: this branch added a
`Sightings` type alias where #22 replaced the file's private `disc_root()`
with the shared `common::disc_root`. Both kept — they are unrelated edits
that happened to land in the same lines.

80 findings, not the 14 the first run showed -- clippy stops at the first
failing compilation unit, so `--keep-going` is what makes the list complete.
60 were machine-applicable (`cargo clippy --fix`). The rest by hand:
* five descending `sort_by` -> `sort_by_key(Reverse(..))`
* `chunks_exact(4)` on both sides of four zips, so the compared items stay
`[u8; 4]` rather than one array against one slice
* three `type` aliases for the census maps and the captured-quad tuple
* `&PathBuf` -> `&Path` in two disc tests
* two range loops; one of them keeps `#[allow(needless_range_loop)]` with the
reason -- the index is into a map's value, which changes each iteration
* the module doc list in `invert_capture` re-indented to markdown's rules
* `blit`'s eight arguments get `#[allow(too_many_arguments)]`, not a struct
One dead `let off = b.len();` in a `ratc` test is dropped rather than renamed.
The sibling test at :162 is the one that asserts an offset; if this one was
meant to as well, that is a test change and not a lint fix.

Before this commit, `unset SYLPHEED_DISC` did not disable the disc-backed
suites on the machine that has the disc: every `disc_root()` fell back to a
hardcoded absolute path that exists on this box. The env var looked like a
control and was not one. Same for $SYLPHEED_RES3D and $SYLPHEED_ISO.
Replace the duplicated resolvers with one `tests/common/mod.rs`:
- 17 local `disc_root()` definitions -> 1
- 7 copies of the skip macro -> 1 (`skip_without_disc!` and siblings)
- 16 hardcoded absolute paths -> 0 executable ones
(3 of those were inline in `mesh_disc.rs`, in no resolver at all,
and 2 were in `examples/`)
- `corpus_report.rs` now reports on the SAME resolver the suites use,
instead of a second copy of the logic its own comments flagged as a
drift risk.
The 17 copies had already drifted into FIVE variants, and they were not all
the same function. `movie_manifest_disc`, `movie_subtitle_disc` and `slb_disc`
honoured $SYLPHEED_DISC and nothing else, while the other 14 fell back. So one
name already meant two things -- a third instance of the shape #16 is about.
The shared helper adopts the env-only behaviour those three already had, rather
than inventing a sixth variant.
Two module docs still described the fallback after it was deleted, which is the
same defect in prose: `texture_disc` claimed "or the default dev path exists"
and `pak_idxd_disc` said "or drop it at the default dev path below". Both now
say what the code does.
Verified both ways on the machine that HAS the corpus, which is the only place
this refactor can be falsified:
A env unset -> "ABSENT -- $SYLPHEED_DISC unset; its suites self-skip"
suites=31 passed=209 failed=0 ignored=14, slowest 0.12s
B env set -> "PRESENT via $SYLPHEED_DISC" (all three corpora)
suites=31 passed=209 failed=0 ignored=14,
slowest 1235.53s (mesh_consistency_disc)
Identical tallies, opposite corpus states, ~10000x apart in wall clock. (A) is
new behaviour -- it was previously unreachable here. (B) proves nothing broke.
`just test-disc` sources `.env` (already gitignored) for the set case. Note the
quoting trap documented there: the corpus paths contain spaces, and an unquoted
`VAR=a b c` parses as "run command `b`", failing silently into ABSENT -- which
looks exactly like a working skip.
Remedy (1) (`#[ignore]` + `--ignored`) is deliberately NOT done here: (3) already
moves the mode from the filesystem into the environment, and `#[ignore]` already
carries three meanings in this directory (corpus-absent, known-failing, bare).
Overloading it a fourth time would re-create the defect.
`cargo fmt --all --check` clean; no new compiler warnings.

`420e84c` claimed the report prints
SYLPHEED_DISC PRESENT via the HARDCODED fallback, NOT $SYLPHEED_DISC
and it did not. The string was built by `"...(not ${env})".replace("${env}",
env)` -- a placeholder substituted at runtime, which printed
`(not SYLPHEED_DISC)` and dropped the `$`. I had cleaned this up before
committing, but the edit silently no-op'd (rustfmt had already rewrapped the
line, so the pattern no longer matched) and the commit went ahead with the
message quoting output the code does not produce.
Now a plain `format!`, which is what it should have been: shorter, no
placeholder to keep in sync, and the `$` makes it read as the env var it is.
The quoted output in `420e84c` is accurate as of this commit.
Not squashed into it because force-push is denied on this remote, and a
visible correction is worth more than a rewritten history anyway.
Verified: `cargo fmt --all -- --check` clean, both tests pass, output matches
the text above exactly.

`cargo test --workspace` reports the same tally whether the disc corpus was
exercised or entirely absent. Measured: the disc suites RAN on a developer
desktop (1936 s, mesh_consistency_disc alone 1220 s) and SKIPPED on CI
(2.4 s total) -- and both reported 207 passed / 0 failed / 14 ignored across
30 suites.
Two mechanisms compound:
* a skip is a PASSING test. The gated suites `eprintln!("SKIP: ...")` and
return early from a test that still passes, so a skipped suite and a
fully exercised one both score 1 passed. The totals are invariant.
* the message is invisible. `cargo test` captures a passing test's output,
so NEITHER log contains a `SKIP:` line. The absence of one proves
nothing, which makes the obvious check useless too.
And `14 ignored` cannot help: `#[ignore]` is static, so that column is the
literal count of attributes in the source and cannot move at runtime. Ask
what this check would still report if the corpus were entirely absent, and
the answer is 207/0/14.
This is #16's remedy (2) -- the only one that touches the REPORT, which is
the defect. Remedies (1) and (3) improve the control and are left open.
Adds `tests/corpus_report.rs`: always runs, never fails, resolves all three
corpora exactly as the per-suite helpers do, and records what was available.
It writes to a FILE rather than relying on stdout, because a passing test's
stdout is captured and would be invisible in exactly the CI log that needs
it; the workflow then prints that file. It also appends to
GITHUB_STEP_SUMMARY when set.
Run here, it immediately shows the thing the issue is about -- all three
corpora resolve through the HARDCODED fallback, so SYLPHEED_DISC is not
controlling anything on this machine:
SYLPHEED_DISC PRESENT via the HARDCODED fallback, NOT $SYLPHEED_DISC
SYLPHEED_RES3D PRESENT via the HARDCODED fallback, NOT $SYLPHEED_RES3D
SYLPHEED_ISO PRESENT via the HARDCODED fallback, NOT $SYLPHEED_ISO
The ABSENT branch is the one CI takes and cannot be reached on a machine
that has the corpora, so `resolve_renders_every_branch` exercises it
directly rather than shipping it unrun -- along with "set but does not
resolve", which is what a typo in the env var produces and which is
deliberately reported as a DIFFERENT state from absent, since the two want
different fixes.
Verified: `cargo fmt --all -- --check` clean. Clippy is unchanged by this
(a test target; CI's `cargo clippy --workspace` does not build test cfg) --
it fails identically on unmodified main here with
`only_used_in_recursion` at vfs.rs:85, which is the rustc 1.90.0 vs the
runner's 1.98.1 divergence, i.e. #15, not this.

`cargo fmt --all -- --check` has failed on every run in this repository's
history, identically on `main` and on every branch. This is #12.
Mechanical: `cargo fmt --all`, nothing else. 154 files, all `.rs`, no other
extension touched. `cargo check --workspace` exits 0 afterwards, so nothing
changed semantically.
ON THE ORDERING, WHICH WAS THE REAL QUESTION.
HANDOFF-2026-09-06 section 7 warns this is the expensive fix: a whole-tree
reformat before #7 and #8 return "would put a conflict in every file of 861
commits and make the reviews those items exist to enable unreadable".
That is measurably too pessimistic, and it had been reasoned rather than
tested. Measured here by three-way merging a rustfmt'd `main` against both
unmerged branches, file by file:
file/branch pairs tested 32
merges CLEAN 28
merges CONFLICTING 4 (8 conflict hunks total)
sylpheed-cli/src/main.rs 1 hunk
sylpheed-export/src/check.rs 1
sylpheed-export/src/screen.rs 4
sylpheed-export/src/video.rs 2
All four are against `auto/frame-blend-draw-path` only;
`auto/port-p6-audio` does not conflict anywhere. The earlier framing --
154 dirty files, 133 that cannot collide, 21 that can, the collision set
carrying 147 of 774 hunks (19%) -- reproduces exactly. What it did not say
is that most of the 21 still merge cleanly, because rustfmt's edits and the
branches' edits rarely land on the same lines.
So the cost of sweeping now is 4 files and 8 hunks for one branch, against
a check that is otherwise red forever. Deliberately NOT folded into the
WASM PR: 154 reformatted files would make that one unreviewable.
Closes#12
`sylpheed-formats` declared `tokio` as a normal dependency and never used
it as one. All four references in its `src/` are inside a `mod tests` --
three runtime builders in ship.rs (539, 566, 690; `mod tests` at 498) and
one `#[tokio::test]` in xiso.rs (182; `mod tests` at 179) -- and tokio was
ALREADY present in `[dev-dependencies]`, so the tests keep compiling
unchanged.
The unused normal dependency pulled `tokio/full`, whose `net` feature
drags in `mio`, which does not build for wasm32:
error: This wasm target is unsupported by mio.
Removing it is right on its own terms; the WASM job is merely what exposed
it. Native is unaffected -- `cargo check --workspace` exits 0 on x86_64.
This is separated from the CI configuration it was found through because
it is the one change here that touches another crate, and #11 is
`state/proposed` around the getrandom error alone. It is ordered first so
that every commit builds: the reverse order would leave an intermediate
commit still failing the wasm check on `mio`.
WARNING: this does NOT reach `sylpheed-export`, which builds
`sylpheed-formats` from the git pin `formats-pin-2026-09-01` (`e2630413`,
contained in `auto/frame-blend-draw-path` only) rather than the workspace
path crate. The dependency is not gone tree-wide until that pin resolves,
so anyone later adding `-p sylpheed-export` to the WASM job will hit `mio`
with this fix apparently already applied.

`ascii_runs` in movie_manifest.rs had a nested `else { if .. }`. Clippy's
`collapsible_else_if` flags it — on some toolchains.
WHY IT WAS NEVER CAUGHT, AND WHY THAT IS THE INTERESTING PART:
clippy::collapsible-else-if @1.92.0 (2025-12-08) -> warn
clippy::collapsible-else-if @1.98.1 (2026-09-01) -> allow
CI installs `dtolnay/rust-toolchain@stable`, which floats. The runner is on
1.98.1, where this lint is allow-by-default, so the Clippy job passed. A local
run on a nine-month-old stable failed on the same bytes. Neither instrument was
broken; "clippy clean" is simply a statement about a toolchain and a date, and
nothing in the pipeline records which. That is #15, and this commit does not fix
it -- it removes one instance of its consequence.
Fixing it rather than pinning, because `else { if }` is worse code on every
version. A tree whose cleanliness is contingent on a release date is the thing
to avoid; agreeing with both toolchains is cheaper than arguing about which one
is right.
⚠️ I FIRST DIAGNOSED THIS WRONG, and the wrong version is worth recording. From
CI's rustfmt reporting 774 hunks and mine reporting 774, I concluded the
toolchains matched, therefore the clippys matched, therefore CI's green must be
a cached or ungated result -- "the frozen splash again". Every step after the
first was false. rustfmt is deliberately output-stable within a style edition;
clippy explicitly moves lints between groups. Measured here afterwards:
rustfmt 1.8.0-stable -> 774 hunks
rustfmt 1.9.0-stable -> 774 hunks (nine months apart, identical)
So formatting parity carries no information about which clippy ran. It is the
same error as reading protection off a settings page or reachability off a DNS
record: a property inferred from something ADJACENT to it. The peer refuted it
by measurement -- `No cache found` in the run log, and `success()` evaluating
'true' in 207 against 'false' in 203 -- rather than by accepting the framing.
Verified on both: 1.92.0 `clippy --workspace -- -D warnings` rc=0 (was 101);
1.98.1 with the lint forced on, 0 sites. rustfmt still 774, so no debt added to
#12. Tests 207 passed / 0 failed / 14 ignored, unchanged.
The lint work added 8 rustfmt hunks. Run 206's Formatting job reports 782
where run 204 reported 774, and the difference is mine — debt added to the
one issue the lint pass argued should not be disturbed. Measured against a
`4ac5c9f` worktree under the same rustfmt, the tree is back to 774: equal
to baseline, not merely close to it.
Two causes, both interactions rather than mistakes of judgement:
`cargo clippy --fix` writes its replacement on one line. Where the call
sat inside a multi-line method chain that produced
.as_chunks::<2>().0.iter()
which rustfmt wants split across three lines. Seven sites, in
`formats/{audio,vfs,game_data}.rs` and `cli/main.rs`. An eighth was a
`for` header pushed past the width limit; it reads better as two bindings
than as a six-line chain, so that is what it became.
The last one is subtler and was the only file left over after the other
seven were fixed. `ship_capture.rs` had
let mut flush = |base: u32,
size: u32,
and clippy correctly removed the `mut`. That shortens the line by four
characters, so the closure's six continuation parameters were then
aligned four columns too far right — a formatting change caused by a
change on a different line, in a file whose own hunk count is what
exposed it.
Worth recording because it generalises: `--fix` output is not rustfmt
output, and on a tree that is not rustfmt-clean the difference is
invisible in the diff and only shows up as a hunk count moving. The check
that catches it is a count against a same-toolchain baseline, not an
inspection of the patch.
Re-verified after the reformat, since these edits changed real lines:
cargo clippy --workspace -- -D warnings exit 0
cargo test --workspace exit 0 207 passed, 0 failed
cargo fmt --all -- --check 774 hunks == baseline

Run 204 gave this repository its first clippy measurement — 48 errors, 43
of them in `sylpheed-formats`. This clears that 43 to zero under the exact
invocation CI runs, `cargo clippy -p sylpheed-formats -- -D warnings`.
Why this crate first, and why it is safe to touch:
Every one of the 43 sites was checked against the line ranges that
`auto/frame-blend-draw-path` (495 commits) and `auto/port-p6-audio` (366)
actually modify. None of them overlap. Eleven of the fifteen affected
files are byte-identical on both branches, including `mesh.rs` and
`texture.rs`, which carry 28 of the hits between them. The three sites in
`audio.rs`, `ui_layout.rs` and `slb.rs` that live in files those branches
do change fall outside every modified hunk. The collision argument that
defers #12 does not transfer here; it was tested rather than assumed.
It also unblocks a measurement. `-D warnings` turns a lint in this crate
into a hard compile error, so its dependents never build — `sylpheed-cli`
and `sylpheed-viewer` have never been linted at all, and viewer is the
largest crate in the workspace. Both depend only on `sylpheed-formats`
(`sylpheed-export` pins it from a git tag instead), so this commit is what
makes their real counts knowable.
38 applied by `cargo clippy --fix` — chunks_exact_to_as_chunks,
manual_div_ceil / is_multiple_of / range_contains, unnecessary_map_or,
needless_borrow, let_and_return, dead_code, unused_mut/variables.
Purely local expression rewrites: 38 insertions, 39 deletions.
2 by hand: a doc continuation that markdown was parsing as a list, and
`d / frame` behind a `frame > 0` guard becoming `checked_div`.
3 `#[allow(clippy::too_many_arguments)]` with a stated reason.
On those three allows: 8 parameters against a threshold of 7, in the mesh
anchor path. The real fix is a shared params struct across
`anchor_pool_mesh`, `validate_block` and `validate_block_report` — the
latter two take the same eight arguments and one delegates to the other —
which is a change to the decoder's signatures and belongs to whoever owns
that path, not to a CI-lint pass.
This is not the shape PROTOCOL.md forbids. `continue-on-error` suppresses
everything, present and future, at the job level, and cannot tell "not
yet" from "no longer". A site-local `#[allow]` with a reason is a decision
recorded where it applies: one lint, one function, and any new violation
anywhere else still fails the build.
`sylpheed-export`'s remaining 5 are deliberately untouched — three of them
sit inside hunks both long-lived branches modify, and that crate blocks
nothing. Left for #13.

Last iteration I proposed that the two sweeps share one indices=8 draw
because ptloop01 links to ptloop02, and said testing it needed a
loading-screen capture I lack. Wrong twice: a linked pair was already in
every capture, ptbtn00 -> ptbtn00f.
Measured: ptbtn00f is drawn ALONE in 899 (f6b) and 1441 (f6) draws and
batched in ZERO, while the sweeps pair up in 1092 and 1744. Linkage does not
batch. The constraint is blend state -- ptbtn00f is additive and its linked
partner alpha-over, which cannot share a draw. The sweeps batch because both
are additive on one page.
Page+blend is necessary but not sufficient: 8154/alpha-over appears as two
separate draws in a single frame, 2108 such draws in f6b. This removes a
wrong cause rather than supplying a batching rule.
Extends read_draws.py to preserve draw grouping (draw index and quad count
per draw); check_labels.py still passes unchanged as a regression control.
Refutation attempt on the port's 0x3002/0x3003 menu-item reading: survives.
958 of 970 stems contain "btn"; the 12 exceptions are psselect_slot and
psselect_slot_blank, which are menu rows.

Adds examples/element_records.rs, which lists leaf AND focus_link records
for an element, plus a disc-wide census. Built because I claimed alpha 80
was undeclared after reading one of ptbtn00's two records -- and focus_link
was already parsed, with ui_layout.rs:424 already documenting the focus
record. The format was known and I did not consult it.
Census: 1467 of 15493 elements (9.5%) across 815 builds carry a second
record whose keyframes are invisible to a by-name leaf lookup.
Refutes our own parser's description of the field. It is documented as "the
focused state of a button", but GP_TITLE has pgloading_loop1 -> loop3 ->
loop4, a chain of three loop animations, and ptloop01 -> ptloop02, the two
sweeps. Neither is a focused state. Naming defect only -- behaviour is right
where it is read -- so not renamed here.
🟡 Notes a better candidate for why the two sweeps share one indices=8 draw:
they are linked, not merely co-textured. Testable on the pgloading chain,
which needs a loading-screen capture I do not have. Named, not claimed.

Three of my errors were the label rather than the measurement, and a
correction in one document did not reach the next page I wrote. The port
built check-authored-vs-declared for values the disc can arbitrate and named
the gap: capture-only values that name an element rest entirely on my label.
check_labels.py closes that for the cases where the identification was
itself made by matching a declared quantity -- 8 checks over two captures,
all passing, with a --selftest that points the plate label at ptcopyright
(the real error) and must fail. It does, at 82-83% against a 5% tolerance,
with the other checks still passing so the failure is localised.
Refutation of the port's "all five figures are also declared": lands for
one. ptbtn00f's peak alpha of 80 is not declared anywhere -- ptbtn00.rat's
parent peaks at 255 and its leaf is one keyframe at 255 flat, with the
120-unit loop declared but no amplitude. The period checks out; the
amplitude is capture-only and their check cannot see it.
Opens a 🟡 not mine originally: the corpus attributes the 120-unit loop to
ptbtn00f, but it belongs to ptbtn00.rat whose leaf is ptbtn00.t32. Left
uncorrected since the identification rests on the period, which holds under
either name.

The port is blocked on what 0x3003 is, having only 0x3002 in its menu-item
rule. The two differ in bit 0 alone. Disc-wide over every .pak: kind&1 ==
has_parent agrees on 15493 elements with 0 counterexamples -- 192/192 for
0x3003, 778/778 for 0x3002, and the same for every other kind. The flag is
exactly redundant with the +32 parent field.
So the bit that differs carries no role information: 0x3003 is a 0x3002
button record that is parented. That replaces the port's circumstantial case
with the field, which is what they asked for rather than a widened rule.
Flags what this does NOT license: it is not a decode of "is a menu item",
and 0x73002/0x73003 (160 elements) carry an undecoded 0x70000 that any
mask-based rule silently decides about.

Build 4 declares ptloop01/02 alpha 0 until t=70, full at t=100, with 238..250
an EXIT ramp -- which answers the brief's "is 238..250 an entry or an exit"
for these elements. Builds 5/6 declare the same records flat 255, so the
build must be named before the question has an answer.
Control ran in the direction that could have flattered the hypothesis and
did not: the leaf's own alpha FALLS 255->128 where the capture RISES 8->255.
Decomposing against the leaf's declared curve leaves an implied parent that
pins at 255.0 +/-1.5 across hundreds of frames while the drawn alpha swings
242->132->145. Parent alpha is multiplied in; closes that standing 🟡.
Restores unit 8's 0.514: leaf/title = 0.4795 and 0.4667 across two runs that
differ 2x in frames. I over-withdrew it last iteration by discarding the
ratio along with the frames it had been quoted in.

The port has no gain anywhere and confirm sits 3 dB above the music. Asked
the disc rather than choosing a number.
Five audio-bearing objects in tables.pak, zero tokens matching VOL GAIN
LEVEL DB ATTEN AMP MIX LOUD. Control passes: the same matcher finds 38
SE_UI hits, so "0 hits" is not a broken matcher.
The negative is stronger than a name search usually is, and I expected it
not to be. Dumping the schema shows the token stream is value-then-key
pairs -- "40, LINE_PITCH", "0, Y_OFFSET_ANALOG_STICK" -- so NUMBERS ARE
TOKENS AND THEY CARRY NAMES. A gain in this format would have a name, and
the name search covers exactly the space where it would live. That turns "I
did not find one" into "one is not there in this file".
Reach, and it is why this is undecodable rather than decoded: I did not
check the .slb bank headers, which is the other conventional home for a
per-wave gain beside a wave index -- and is where the play-test's own
framing points. No .slb exists as a loose file on the extracted disc, so it
costs a pak extraction I did not have budget for; it is the first thing the
next attempt should do. Nor did I check the executable, where a mix could
be immediates in the sound-play path around sub_821C5580.
So this is not "the mix is not on the disc". It is "the mix is not in the
table where a cue's fields live".
Pointer, not a finding: object #15 lists po_sound_scr.prt -> SOUND among
GP_OPTIONS' screens, so a user-facing sound options screen exists and at
least one volume is runtime state.
Port keeps authoring nothing yet.

The blend bit has been decoded against RB_BLENDCONTROL0 since 2026-08-31,
but ui_layout::blit could not draw it, and said so in a comment citing a
refutation that is <render-vs-capture> -- this renderer disagreeing with
itself while it had a stale keyframe association, no leaf geometry and no
rotation.
The consequence the port raised: verify-screen compares two renderers, so a
renderer that structurally cannot express a declared field makes the check
incapable on every screen that uses it -- 12 of 16 -- and the tolerance
silently excuses all of them. A quiet check is worse than a failing one.
Both equations come off the game's own pixel shader, which premultiplies
(oC0 = rgb*A, A), so only the blend register differs: 0x07010701 gives
rgb*A + dst*(1-A), 0x01010101 gives rgb*A + dst. Additive therefore
saturates rather than wrapping, and a transparent or black source is the
identity -- neither is a choice.
No plumbing needed: t8ad::parse already stores +0x04 as T8adImage::flags.
Four controls, pinned against arithmetic per the rotation precedent. The
fourth is the only one that can fail for the right reason: the first three
pass just as well if blit ignores the flag and draws everything additive,
so the discriminator flips only the blend on one sprite and requires two
different answers, each equal to its own equation. That is the same failure
class as the port's non-inverting latch check and my own backward scan that
resolved every guard to "internal".
120 passed, 0 failed on the full lib suite.
67 sprites over 14 screens were being drawn with the wrong blend, including
10 of 18 on the title and ptbtn00f, the PRESS (A) plate's highlight.
R1: tools/stale-instrument render-vs-capture lists 8 claims that died to
this instrument, including both legs of the rest() pair and "the plate-free
title capture may be too early to be settled", which sits on play-test
finding 3. None is re-derived here; this only records that the instrument
no longer exists in that form.
Also corroborates the port's H5: pgloading_loop5 is an ELEMENT resolving to
sprite pgloading_ring.t32, which is additive. I could not find loop5 as a
sprite in any pak and nearly reported a false contradiction from the
element/sprite name split.

Play-test finding 4, answered as a mechanism and from the disc, so it
generalises instead of describing one boot.
ui-splash-draw-pass.md excluded a post-process from GPU state and closed
with "that softness is in the texture or in which quads are drawn, not in
a pass", leaving the two unseparated. It is both, and they are one fact:
each logo ships a second texture that IS the blur -- the same artwork
outset by exactly 10 px per side, concentric to <=1.5 px, drawn as its
own alpha-over quad.
Three results, each with its control:
* The capture's eight anonymous quads are NAMED from the disc. Predicting
each NDC rect from declared position + decoded sprite size matches all
eight bijectively; every match <=0.0061, every runner-up >=0.0272, a
4.5-8.9x margin. That margin is the control -- eight similar boxes
would match anything.
* REFUTES splash-quad-timeline.txt's "the same three rects scaled
slightly larger" (my own earlier wording). The x and y scale factors
differ by up to 0.28; a uniform scale cannot do that, a fixed 10-px
border can. The conclusion it supported (draw all six quads) stands;
the model was wrong, and the wrong model tells a port to scale a
sprite.
* The T8aD blend bit tested OUT of sample on entries 10/11, which were
not in its 35-row fit and are the screens under complaint.
Pre-registered additive=false for all eight against 0 additive draws in
1048; held 8/8, with the control still reporting 9 additive on entry 6.
Also resolves a REFUTED.md 🟡 <our-reader> in the reader's favour: the
prediction is ours and the target is the oracle, so the agreement is
evidence about the reader rather than a claim resting on it.

`ui-blend-mode-decoded.md` established the field but nothing on `Element`
reached it, so the exporter could only key a blend map by SCREEN NAME --
which asserted-by-omission that the Japanese menus blend differently from
the English ones.
Adds `sprite_header_word_04`, `header_word_04_by_name`,
`sprite_blend_additive` and `blend_additive_by_name`, plus
`examples/blend_api_check.rs`: the accessor the exporter will actually
call, checked against the same 35 oracle rows read out of the guest
command stream.
22/22 agree, 0 mismatched. The control requires entry 6 to report BOTH
values (additive=9, alpha-over=7), so an accessor stuck at one answer
fails rather than scoring 100%.

The human asked both agents for a critical retro; it reached me relayed through
sylpheed-port, and I am treating it as a message rather than as their word while
staying paused on RE iterations.
Worst failure first: I READ the refutation that mattered and routed around it
instead of auditing it. REFUTED.md killed the blend bit with our own renderer as
its instrument, and I quoted the 'a claim resting on our renderer is a claim
about our renderer' rule at the port in the same session while not applying it to
my own register.
Underneath it is the sharper one: I twice accepted render-derived labels for a
disc-side question. My 'no field separates them' negative was tested against a
partition that was wrong in six places, all six of which the oracle later called
additive.
Also recorded: the silent vertex truncation, a coverage claim written rather than
computed and wrong by four, a batching generalisation refuted by the log it was
written from, and navigation whose fix was worse than the bug.
Two additions to the port's list of shared costs: neither of us has ever given a
negative a positive control, so 'absent' and 'my search does not work' are
indistinguishable in every undecodable page I have written; and we keep
attributing a three-way residual to whichever leg we happen to be looking at.
Their eight proposals attacked one by one -- P2 sharpened into a
re-classification rather than bookkeeping, P5 pushed back on ('suppression
localises disagreement; only the oracle labels it'), the rest agreed with
amendments.
And the check the retro forced: my rival sweep covered the T8aD header and not
the 60-byte declaration entry, whose earlier hunt used the corrupted labels. Swept
properly, 16 of the 35 measured elements have no declaration entry at all and 0
declaration bits separate the other 19. The decode is not underdetermined -- run
because it could have gone the other way.
The PROTOCOL delta is presented, not applied.

sweep_leaf_ramp dumps the nested ptloop01/ptloop02 leaf keyframes -- position,
alpha, rotation, scale and time -- which is where the ramp the port asked for
actually lives.
sweep_positions now also pools alpha against position per strip and prints the
slope, with the quantisation stated: NDC prints to two decimals, so one frame's
dx is 6.4 px and alpha is one level, and at three or four frames the two
declared slopes (+0.0814 and -0.0651) are inside that noise. It is a direction
and magnitude check, not a discrimination.

REFUTED.md kills this claim: 'T8aD +0x04 bit 0x02 selects an additive blend ->
mine, and refuted. Blending those sprites additively worsens every measure
against the capture.' That refutation rests entirely on our renderer, which the
corpus's own rule calls a hypothesis under test. The blend is now measured off
the GPU, so the claim can be tested against the oracle.
35 elements over three screens, every label an RB_BLENDCONTROL0 value read from
the command stream: 16 bit-set and additive, 19 bit-clear and alpha-over, zero
false positives, zero false negatives.
The control that makes it a decode rather than a coincidence: of every bit of
the first 12 header words, EXACTLY ONE separates those 35 elements without
error. Nothing ties with it. A perfect partition on a small sample is worthless
if half the header partitions equally well, which is the mistake +0x08 = 0x8050
was.
And the pair no confound survives: ptbtn00 = 0x0110, ptbtn00f = 0x0112 -- the
PRESS (A) plate and its own highlight, same screen, differing in exactly this
bit, drawn alpha-over and additive respectively.
Committed alongside is a PREDICTION for GP_OPTIONS, written before the capture
that tests it: a different archive, a different element set, and a MIXED
prediction -- po_menu_eff01/02/03 additive, 592 elements alpha-over. Falsified
if those three draw alpha-over or anything else draws additive. The developer
splash was considered first and rejected as a test: both its elements predict
alpha-over, so it can fail but cannot discriminate.

The four elements the port measured as the worst on EXTRAS, and which appeared
in no draw, were in a draw all along: the 24-index additive batch holds six
quads and Canary printed the first two. Cap raised to 64, screen re-captured,
all six named. Same draw as ptframe3, whose state was already measured -- the
one-way implication doing real work.
pteff10 is identified too, and it needed the resting SCALE: it ships as 409x144
and is drawn at 200 % x 500 % = 816x720. The matcher's 'try 1x and 2x' rule
could not name it at any scale and reported a near miss against something else,
which is a failure wearing the clothes of an answer. Candidates are now the
declaration's pivot*2 scaled by the resting keyframe as well as the texture at
1x and 2x, and the tolerance is the log's own NDC print quantisation rather than
a chosen number.
Flagged rather than buried: pteff10 measuring additive is in tension with the
port measuring it nearly exact under alpha-over. Both can be true for a dim
semi-transparent glow over a dark background, and it is the one row a rendering
check does not corroborate.
Also stated: the three full-screen alpha-over draws are NOT individually
identified -- four elements declare 1280x720 -- so the label on those rows is a
candidate, not an identification.

menu_blend_capture.sh counted two DOWNs to reach EXTRAS, which is wrong twice
over -- EXTRAS is the fifth item, and on 2026-08-31 four DOWNs landed on OPTIONS
because one press was dropped. It now presses until the cursor stops moving,
which needs no item count and no row calibration. Its title deadline follows the
same change as title_blend_capture.sh, 1200 s not 420.
ui_blend_map.py takes a comma-separated build list, because the live title is
TWO builds composited -- 4 draws the art, 2 draws the PRESS (A) plate -- and a
one-build size table cannot name the elements of a title capture.
frame_alpha_census takes its builds from argv for the same reason.

The declaration entry's kind word (+0x28) and its focus/nav index (+0x2C) are the
same fact twice: kind & 0x2 is set iff the focus index is >= 0. Checked over 24
UI paks and every parseable build in each -- 1062 focusable elements, 14431 not,
zero exceptions. The test is two-sided, so it would fail if any focusable element
lacked the bit or any non-focusable element carried it.
Consequence: kind == 0x3002 is not the test for a button. It catches 778 of 1062
and misses 284 (26.7 %) at 0x2, 0x2002, 0x3003, 0x73002, 0x73003 -- including
ptbtn00.rat on GP_TITLE's PRESS (A) plate, which is 0x73002. And 0x3000, 817
elements, looks like a button and is not focusable.
This is also the refutation attempt on sylpheed-port's kind census. Their claim
-- every decoration 0x0, every button 0x3002 -- is exactly right on the two
screens they checked, reproduced here independently, and fails one build over on
the title they have not run yet.
The other kind bits are reported as observed structure and explicitly not
claimed.

The port measures four elements as rendering too dark against the capture --
ptframe1/2 on the main menu, ptframe3/4 on EXTRAS -- with the shortfall
correlating +0.77/+0.80 with the BACKGROUND and only +0.24 with the element's
own contribution. That is the signature of a blend that scales what is already
there. It asked whether the disc selects one.
Three examples, one negative, wider than the one I gave last iteration:
* frame_alpha_census -- every T8aD sprite on builds 5 and 6 by alpha. It
REFUTES the port's own sharpener: 'neither frame has a single fully-opaque
pixel, against ptbase's 99.1 %' is true, and pteff10 (max alpha 130, 100 %
partial, no opaque pixel) is measured by the port as NEARLY EXACT. So being
wholly semi-transparent is not what makes the frames special.
* frame_vs_accurate_words -- all 12 T8aD header words for both screens, plus a
per-BIT sweep of +0x04 and +0x08. NO word and NO bit puts the four frames on
one side and pteff10 on the other. It also kills my own remaining candidate a
second time: +0x08 = 0x8050 is shared with pteff21/22/23 on EXTRAS.
* frame_keyframe_unknowns -- the keyframe record's fade, tint, rotation and its
two unexplained signed words. unknown_4 and unknown_8 are ZERO on every
keyframe of both screens, so they carry nothing here; no frame takes a value
of any field that another element does not.
Reach: the 60-byte declaration entry, the T8aD header word-wise and bit-wise,
and the keyframe record. Four elements, two screens. Not the executable's draw
path, which is the next commit.

Answers the port's ask about ptframe1/ptframe2, whose residual is uniquely higher on
flat pixels than edges and signed one direction -- a body-intensity difference.
Prior work covers .prm primitives and a refuted T8aD +0x04 bit; neither covers a
.t32 element. All 15 words of the 60-byte declaration entry are read: 3 are the
name, 8 constant, the rest kind, focus index, position and pivot. The frames are
kind 0, identical to every other plain sprite.
One candidate found and refuted by myself: T8aD +0x08 is the only word where both
frames agree uniquely on that screen, at 0x8050 -- but 38 sprites carry it
disc-wide, only 8 named frame, and the high byte tracks the archive. It is an
atlas/format word, not a mode.
Also records a false positive of my own test: +0x00 and +0x08 first read as
'separating the frames' because those words are the name string.
So any blend the port picks is authored. Reach: not looked at the executable's draw
path, where a mode selected in code rather than data would live.

sylpheed-port mapped the menu's edge residual at 64 px tiles and handed over
coordinates without names, which is the division I proposed: the map is theirs, the
element inventory is mine.
Under the hot band at x 384..704, y 64..256 sit ptframe1.t32, ptbtn01.rat (the NEW
GAME button) and pteff12.t32, an effect element -- all three hot under BOTH
coordinate readings, so the answer does not depend on whether their tiles are in
design or capture space. ptbtn02 is hot in design space only.
So the hot region is not one element but three of different kinds overlapping, which
is consistent with their null: they looked for two families of tile and found one
continuous population, so the region has no character of its own.
This names what is there, not what is wrong -- their map already excludes local
displacement in these tiles. Also records their control limit: a +2 px displacement
reads back +0.839 because the slope saturates, so any slope they report is a floor
on the displacement and never a ceiling.

sylpheed-port turned my point -- that a static record still declares a cycle, so a
nonzero +0x08 against a largest time of 0 is a real disagreement -- into a check on
the screens they ship. Re-derived from my reader and it reproduces exactly: 65
nested records in GP_TITLE, 20 declaring a cycle with every pose at t == 0, and 0 of
those with any element carrying more than one pose.
A record whose elements each hold a single pose renders identically looped or held,
so holding them still is correct and now measured.
It includes ptbtn11/12/13, EXTRAS' buttons in both language entries, each declaring
120 units with one pose per element. Had any carried two poses, a menu button the
disc says animates would have been held still on the one submenu the port's P5 gate
walks.
Reach: GP_TITLE only; 1530 static records exist disc-wide against the 20 here.

sylpheed-port corrected their own reconciliation and I reproduced it: 0 nested
records on this disc lack a timed keyframe. All 1530 are static -- timed, every pose
at t == 0 -- so the question is well-formed there and 'not exact' is a real answer,
not an absent one. A static record still declares a cycle length.
So the two percentages are two populations and neither corrects the other: 92.3 % of
animated records, 49.6 % of all nested records including static ones, same numerator
1643. Both need their population attached.
Two wrong explanations preceded this, both mine to carry: that my scan filtered
untimed records, which .max() returning Some(0) prevents, and then their 'questions
never asked' framing which I adopted.
The page is rewritten to the settled state rather than stacked. Nothing the port
depends on moved at any point.

sylpheed-port reconciled the population gap exactly and I reproduced it: filtering
max_t > 0 gives 1781 records and 92.3 %, their figures precisely. Same numerator,
1643, both ways.
My stated explanation was wrong. I said the scan requires a timed keyframe; it does
not, because .max() returns Some(0) rather than None for records whose keyframes are
all at time 0, so 1530 records where the question has no content stayed in my
denominator and counted as failures by construction.
The conclusion is untouched -- +0x04 is 0 % under either denominator.
Records their diagnosis of why it stayed invisible: the numerator agreed to the
unit, so a shared 1643 read as agreement and neither of us looked there. And both
halves needed a qualifier neither carried -- 92.3 % is of the records where the
question is meaningful, not of nested records.

sylpheed-port aimed my own boundary finding at my loop-length control. Reproduced
from my reader over every pak: +0x04 has 0 violations too, so the falsifier rejects
+0x0c and accepts +0x04 and never discriminated. What identifies +0x08 is the
exactness statistic the page presents as secondary -- exact match in half the
records against 0 % for +0x04.
Population differs from theirs, 3311 records against 1781, because this scan takes
every pak and requires a timed keyframe, so the percentage moves but the
discrimination does not.
Second time this week with the weight on the wrong leg: a count taking credit for an
exclusion argument, now a falsifier taking credit for an exactness statistic, and
both times the real discriminator sat beside it described as a formality.
Their general form is sharper than my boundary rule: an interior consistency check
is satisfied by any internally consistent reading, and that is what a wrong offset
into a regular structure usually is.

The two adjacent pairs with identical element sets split. 0/1 are the same 59 810
bytes stored twice -- a duplicate, not a language pair. 2/3, the DIFFICULTY build,
differ in size and in 2.77 % of bytes from offset 0x1BB while sharing every element
name, which is what a language pair looks like.
Control: entries 10/11, known to be two different dialogs, differ in 54.90 % of the
common prefix, so the comparator separates unrelated dialogs.
Supported, not proven, with the untested step named: I have not captured DIFFICULTY
in ja. That the two are ENGLISH and JAPANESE rests on the disc's convention, not on
a capture of this screen. This partially restores a claim I withdrew, at lower
strength than the original phrasing.

Both agents left the language reading standing for the 37 pairs that differ without
a button-count mismatch, and both observed that nothing rewarded closing it. Two
scans closed it, against my own reading.
All 39 equal-button-count pairs share button names and rows exactly, which does not
settle it -- two dialogs sharing a button template look identical by that test. What
differs does settle it: pzstg10 against pzstg02, pzstg11 against pzstg03, pzstg12
against pzstg13. These are the DLG_STAGE_TITLE01..16 dialogs and an adjacent pair
carries two different stages, with different sprite counts, which is a different
amount of text rather than a translation of the same text.
So the whole 63 is explained by one fact -- adjacent entries are unrelated dialogs
-- with no residue. The 2 identical pairs remain unexplained but are no longer
anomalous against a hypothesis, because the hypothesis is gone.
Recorded about process rather than the disc: a bound nobody is incentivised to test
is exactly where a convenient claim survives, and the next reader cannot tell
whether a bound was respected or merely never revisited.

sylpheed-port refuted the untested reading I recorded yesterday with a count, and I
reproduced it: 26 of 65 adjacent GP_DIALOG pairs differ in BUTTON COUNT, which two
languages of one dialog cannot. The names agree once read rather than counted --
ranking_NEXT against ranking_JUMP, py_ranking against pzeff, pzstg10 against
pzstg02.
So adjacent entries are unrelated dialogs, the 63 never needed the language
reading, the 2 matching pairs need no special account, and the 140:70 ratio is a
counting coincidence -- the same fact my halves-pairing zero was showing from the
other side.
Preserving their caution: this does not establish that 0/1 and 2/3 ARE language
pairs. Identical element sets is equally consistent with a duplicate, and for the
37 pairs differing without a button-count mismatch the language reading is
unsupported rather than refuted.
Withdraws a delivered claim: I called entries 2/3 'an EN/JP pair' in HANDOFF. The
DIFFICULTY identification does not rest on it -- unique geometry plus the capture
does -- but it was stated as fact and was not one.

GP_DIALOG has exactly 140 entries against the table's 70 records, a 2:1 ratio that
would make the unbound join an ordering question. It does not hold: adjacent
pairing gives identical element-name sets on 2 of 65 pairs, halves pairing on 0.
GP_TITLE's language pairs share element sets exactly, so identical sets are the
signature there; in GP_DIALOG almost nothing matches.
Residual and unexplained: the only two adjacent pairs that DO match are entries 0/1
and 2/3, and 2/3 is the DIFFICULTY build.
A reading I am not asserting: dialog text may be baked into language-specific
sprites, which would explain the 63 by construction but leaves the 2 needing their
own explanation. Not tested.
The join stays unbound; positional ordering is now ruled out, which narrows where
to look next.

Chasing the reach I recorded this morning found the binding it said was missing.
Every DLG_ string in the image is pointed at by one aligned word at a 12-byte
stride: {u32 handler, u32 id, u32 name_ptr}, spanning 0x820A0A2C..0x820A0D68 with
three distinct handlers. Complete -- 70 names, 70 records, none unmatched -- and the
ids are banded and monotonic with a single gap at 24. Read from the image directly.
Refutation attempt on the shared reach, which both agents had recorded: 'another
four-button dialog with the same rows would be indistinguishable'. Scanned every
build in every pak for four buttons within 6 px of 259/329/399/469. Control found
both incumbents; zero rivals exist anywhere on the disc. So the geometric
identification is unique disc-wide, which is stronger than what either of us
claimed.
Still unbound: id 2000 to a pak entry. The tie remains uniqueness plus the oracle
capture, not a pointer.

Closes a negative of mine whose failed assumption I had named: I searched for an
8-record btn-named build in an archive of its own, assuming DIFFICULTY's four items
pair with f variants the way GP_TITLE's screens do. It has its own prefix and is
not a GamePart screen at all.
Three independent routes agree. The image lists DLG_SELECT_DIFFICULTY among the
DLG_* dialog names at 0x820A41BB, and GP_DIFFICULTY appears zero times. GP_DIALOG
entries 2/3 are the only builds there with pcbtn00..03 -- four buttons at design
rows 259/329/399/469, spacing 70, an EN/JP pair. And my capture of the running
screen puts its four rows within 4 px of those, with spacing 70.5/69.5/70.0 against
the disc's 70/70/70.
Reach stated: the entries are identified by button count and geometry, not by a
binding from the DLG_ name to a pak entry. No such binding was found.
Also notes the consequence for Q6's count-match: NEW GAME opens a DIALOG from an
external archive, which still matches the count but is not the same category as
OPTIONS or TUTORIAL opening a GamePart.

Serves Q6's open question. boot-config-and-gamepart-registry.md records a
count-match for the title part's event numbers -- four menu items load an external
archive, EXTRAS stays inside GP_TITLE -- explicitly as an observation rather than a
decode. Half of it is disc-checkable and now has support.
Every button record in all 16 GP_TITLE entries: ptbtn00 (the plate), ptbtn01..05
(main menu), ptbtn11..13 (EXTRAS). No fourth button screen, so no DIFFICULTY build,
and DIFFICULTY is what NEW GAME opens. The other four destinations have their own
paks -- GP_OPTIONS, GP_SAVE_LOAD, GP_TUTORIAL -- while EXTRAS' two children are
GP_MISSION_SELECT and GP_MOVIE_THEATER, so EXTRAS is internal and its children are
not.
Still NOT a decode of the event numbers: the shape the count-match asserts is real
on the disc, but nothing shows a given event is a given row.
Negative recorded with its reach: DIFFICULTY's build is not located. I searched for
an 8-button-record build on the assumption its four items pair with f variants, as
GP_TITLE's screens do. They may not, so the negative is narrower than 'not found'.

No new boot was spent: six runs had already captured the first menu entry of a
fresh boot, and all six read NEW GAME. Three of them follow a session that ended
with the cursor on EXTRAS or OPTIONS, which is what makes it a test of persistence
rather than a repeated observation.
Reach stated rather than implied: every session ends with the emulator KILLED, so a
game that writes menu state on a clean shutdown would never get the chance. This
measures 'does not survive a killed session'.
Refutation attempt on the port's extras/initial_focus: ptbtn11 -- it SURVIVES.
ptbtn11 is the top button on the EXTRAS build, with the main menu as a control
where ptbtn01 is top and is known to be NEW GAME.
Incidentally corrects ring_row.py's stated calibration. It cited capture_y = 49.5 +
1.060*design_y, fitted against menu_focus.py's row centres, which are NOT the
disc's button rows -- the disc says 162/242/322/401/482, spacing 80, and
menu_focus.py drifts up to 17 px against them. Re-fitted: 64.82 + 0.9919*design_y,
residuals under 0.7 px. No item assignment changes.
