re(media): the disc ships movies in TWO audio profiles, and 28 of them are 5.1
Probed all 97 movies. 28 are wmapro 48 kHz 6-channel 5.1 -- ADV.wmv and every S*.wmv story cutscene; the other 69 are wmav2 48 kHz stereo, every RT*.wmv and hokyu_*.wmv. The split is cinematics vs in-mission radio chatter. Both movies the menu milestone needs, ADV.wmv (the boot/attract intro) and S00A.wmv (the new-game intro), are in the SURROUND group. Why it matters: one ffmpeg command over dat/movie/ produces two different kinds of result and records neither. The 69 stereo files pass through unchanged; the 28 surround files get downmixed 5.1 -> stereo by ffmpeg's DEFAULT matrix, folding centre-channel dialogue into L/R at a weighting nobody chose and which is not stable across ffmpeg versions. That is a content decision inherited by accident, so it should be stated explicitly and recorded beside the command. Credit where due: found by the human while checking a transcode, verified independently here and widened from one file to the whole disc. Two METHOD entries from the same episode, both about measurement rather than format: don't probe a file another process is still writing (a half-written transcode reported 33 s against a 137 s source, no error, nearly a filed bug), and a difference-signal RMS is meaningless before cross-correlation alignment (-34.2 dB against a -25.3 dB source looks like failure and is inconclusive). |

re(ui): the focus ring SPINS, the game draws it, and the leaf owns the f record
Three things, all from parsing ptbtn0Nf.rat as a build. 1. THE RING SPINS. Its two keyframes differ in exactly one field: rotation_deg ramps 0 -> 360 with position, scale, alpha and tint all constant. A spin in place, the same shape as the GP_BUNK example already recorded. 2. THE ORACLE CONFIRMS THE GAME RENDERS IT. In the OPTIONS-focused capture the ring's bright head sits in a completely different angular position from the sprite's own -- caught mid-spin. This is a SECOND independent confirmation that rotation_deg is drawn, now on a different screen and a different element from the ptloop sweeps, and it raises rotation's priority: it is not a title-only concern that sits off-screen at rest, it is the main menu's focus marker. NO ANGLE IS QUOTED. A brightest-region centroid says ~250 deg, but the control refuses that precision -- rotating the sprite by a known 30/90/180/270 and re-measuring gives errors up to 19.8 deg. What survives the error bar is that a <=20 deg error cannot manufacture a ~250 deg displacement. 3. WHICH PLACEMENT WINS -- correcting this page's own earlier caveat, which said to use the leaf only for elements the parent does not declare. Right for a BASE record, wrong for an f record: the parent declares NO element for ptbtn0Nf.rat at all (zero of build 5's 16), so the f record's placement comes from its leaf for BOTH elements, label included. The label's (-7,-7) is load-bearing -- the f sprite is 13px larger per axis and -7 keeps them concentric (535+96/2 = 583 vs 542+83/2 = 583.5). Corroborated against the oracle: the focused-minus-unfocused region is x 505..703, and the leaf predicts a right edge near 707 where the parent reading predicts 714. Also exposes UiBuild::records (name -> (offset, size) of a nested .rat leaf). Nested records were parsed into a PRIVATE map, so a consumer holding a UiBuild could not locate a leaf's bytes at all -- which is exactly what blocked the port from reaching the ring. |

media: expose se_wave_riff -- the menu's SE cues, assembled where the format lives
The port is forbidden from reimplementing media assembly and Static.slb is exactly that case: no RIFF, no seek chunk, no XACT container, just a packed run of whole 2048-byte XMA1 packets, so a wave is defined only by (offset, packet count) and the header has to be synthesized. That step now happens once, in the crate that owns the format, instead of in each consumer. `slb::xma1_wave_riff` wraps raw packets; `media::se_wave_riff` looks the bank up and reads just the packets asked for. Both reuse the existing synth_xma1_fmt / build_riff, which are already byte-identical to what tools/re-capture/ slb_extract_wave.py writes -- so this is exposure, not a second implementation. It reads a TARGETED range rather than the whole bank, and that is load-bearing: Static.slb is the ONE entry of sound.pak's 9 519 whose declared extent runs past the end of the extracted segments -- by exactly 616 768 B -- so reading it whole fails outright on this extraction. Every cue we need is in the first few hundred KB. Recorded rather than worked around silently. Verified as an artifact, not a compile: all three cues decode through ffmpeg to mono 48 kHz PCM at 0.533 / 0.344 / 1.016 s, non-silent (rms 2085 / 2985 / 4327, peaks 29813 / 16973 / 32767). The refusal path is exercised in the same run -- an impossible packet count is rejected rather than returning a short stream, because a truncated XMA decodes to plausible-sounding garbage. Also adds docs/re/captures/ORACLE-CAPTURES.md: an index of the nine canary framebuffer captures already in this repo, and a plain statement that THEY are the reference and `screen render` is not. |

re(ui): the focus ring's position is decoded -- a .rat leaf parses as a build
The port needed ptbtneff01.t32's placement and was about to author it from an eyeballed PNG measurement. It does not have to: a `.rat` leaf needs no new reader. Its first 32 bytes have a bundle header's shape -- "RATC", 0x3c declaration-entry size at +4, element count at +20, design 1280x720 at +24/+28 -- so ui_layout::parse_build reads it unchanged. The control is the base record, whose position is known independently: the parent screen reports ptbtn01.rat resting at (542,162), and parsing the leaf alone returns ptbtn01.t32 at (542,162). It reproduces all five buttons. Positions are absolute design-space top-left. The ring rests at (500, 156/236/ 316/396/476) for buttons 1-5 -- a uniform (-42,-6) from each button's own rest, identical in the Japanese bundle. The bright label is a uniform (-7,-7). Two things recorded rather than smoothed over: a leaf's placement DUPLICATES the parent's rather than being relative to it, and the two copies are not always byte-equal (ptbtn04's parent says y=401, its leaf says 402) -- the parent is what compose honours, so the leaf is the source only for elements the parent does not declare, which is exactly the ring. And `screen render --focus` is blind to the ring for the same reason the port's exporter was: el.focused is name-based on top-level elements and neither walks into the leaf. |

re(ui): answer four of the port's five asks -- splash, fade-out, focus, gamma
1 SPLASH ADDRESSING (was blocking P3). No content predicate exists: design size fails (every extra composable bundle sampled is 1280x720, like every screen) and element count fails (fragments run 2..15, the splash halves are 3 and 7). But GP_TITLE needs none -- `--all` adds exactly four bundles there and all four are real screens, with the --all index equal to the pak entry index 1:1. And there are TWO splash screens: 11/14 are the developer logos, 10/13 are the SQUARE ENIX publisher wordmark, which the port did not have and which the boot shows first. 2 FADE-OUT (was blocking P3). It is (a), and it is bigger than the fade quad. Every element ends on exactly ONE untimed keyframe, which rules out (b); that block is where the screen plays out -- quad to a=255, buttons/labels/glows to a=0, frames hold. (c) is refuted by a null test that discriminates: a black quad alone holds the button/background brightness ratio constant, and through the fade it falls 6.50 -> 1.94, 3.4x monotonic. 3 FOCUS (saves P5 rework). Over-vs-instead is unobservable -- the focused sprite covers the base at 100.0% of base-visible pixels on three pairs once aligned (true offset (7,7); the centre alignment reads a misleading 78-84%), and compositing both ways differs by RMSE 1.1 inside the button rect. The real defect is the focus record's SECOND element: ptbtn0Nf.rat declares ptbtneff01.t32 (a 42x46 glowing ring, focus only) plus the bright label, where the base declares one sprite. That ring is the marker the port draws nowhere. 5 GAMMA. The capture is not neutral: capture ~ 255*(render/255)^g, g ~ 1.34-1.49, and the chain says it is a ramp the GAME installed, not a capture artefact. So RMSE against captures has a floor. Reach stated: the flat patches are all dark (render ~0-60), so midtones and highlights are unconstrained. 4 ROTATION is a human's call and is recorded in MISSION, not acted on -- the port rotating while the reference renderer does not would make verify-screen report a large diff meaning "the port is right". The RE half is answered: rotation is about the declared pivot, measured against a GPU capture. The focus record's +20 element-count word is marked 🟡 not ✅ -- read on GP_TITLE's ten button records only; the disc-wide check is written and still running. |

Two runs were killed this session for looking stuck. Measured: 1 318 s serial, no output while it runs. Also records that `build-reborn test` forces --workspace and silently ignores a `-p`, so scoping needs the cargo passthrough (`build-reborn t -p <crate>`). |

re(ui): the 60 nameless RATC children are frames, not children -- .tan decoded
Closes the reach caveat the `opt ` name fix left behind: 60 of 18 002 RATC children carry no `opt ` block, and it was not established whether they lack one or sit past our 128-byte window. Neither. They are not children. `examples/ratc_optless_children.rs` re-runs `ratc::parse`'s own guards over the disc and reports which one fired: all 60 are "tag beyond the window", none is rejected by length, gap or charset, none is child #0, and all 60 live in six bundles of one archive. Within a bundle the distances back to the nearest tag are an exact arithmetic progression, step 60 600 -- ten different records finding the SAME tag, because there is only one. Reading a bundle directly: children 1..10 are equal-size T8aD blocks under a single `opt ` name, `pb_f15_eg_anm.tan`. `.tan` is a FRAME SEQUENCE. One block declares the resource; its payload is a run of T8aD frames. Disc-wide, over all 18 718 `opt ` names in all 33 paks: a RATC bundle names exactly six kinds of resource -- `.t32` 14 756, `.rat` 3 311, `.prm` 367, `.tbm` 224, `.sbo` 54, `.tan` 6. Six `.tan`, ten frames each = 60, the entire population with nothing left over. The negative is closed, not narrowed. Consequence recorded but deliberately not fixed: `ratc::parse` over-reports there, listing a `.tan`'s frames as anonymous children. Nothing in the menu milestone reads a `.tan` -- it occurs only in GP_READY_ROOM, which S1 ruled out -- so no screen the port draws changes. Also a METHOD entry for this container OOM-killing `slb_leading_segment_disc` under default test parallelism (SIGKILL, no assertion; 8/8 pass with --test-threads=1). |

re(ui): a RATC child's name is stated, not inferred -- and it was hiding every menu background
`ratc::parse` named each child by scanning backwards for the last printable run of bytes before its magic. The format states the name explicitly instead, in an `opt ` block: `"opt " | BE32 len | name | NUL | 3 bytes | magic` -- the same block `ui_layout::opt_link` already read for a button's focus link. The scan agrees with it 17 918 times out of 17 942 and is wrong 24 times, every one the same failure: the 3 trailing payload bytes are themselves printable and beat the real name. For `pteff05.t32` those bytes are `38 41 58` = `8AX`, so the full-resolution background of all five menu screens registered under a name no element declares, resolved to no sprite, and `compose` dropped it through an early `continue` that -- unlike the two arms above it -- records nothing. The screen lost its background and `screen render` still reported "all resolved". `8AX` was never a name. Docs that treated it as one are corrected here. Disc-wide, and the control is the 17 918 the scan already got right: the `opt ` reading reproduces every one of them. Effect on the five screens is the signature of the same art at twice the resolution -- mean brightness unmoved, high-frequency detail x1.15..x1.30 -- which is what the separately-measured `ui-8ax-fullres-background` result said the game draws. Also closes a long-standing dangling reference: `pmbase.t32`, recorded as "on the disc nowhere", is the `GP_STAGE_CLEAR` child the scan called `8AX`. RATC sibling references now resolve 10 148 of 10 148. Verified: 114/114 sylpheed-formats unit tests (including two new ones pinning the `8AX` case byte for byte and the no-block fallback), and every disc-gated integration suite in sylpheed-formats/sylpheed-cli. |

docs: withdraw yesterday's "paint order is a sequence" -- wrong source
Last iteration I claimed the splash's measured_paint_order [0,2,4,6,1,3,5]
records, between its glow and logo halves, the temporal order they were
seen in rather than depth -- because the halves never share a frame.
The no-overlap measurement is right (glows f94-115, logos f116-211). The
inference is wrong, on two independent grounds:
* Wrong source. That vector is not a read of the draw capture. It is a
read of the live screen object's CHILD ARRAY -- ui-screen-runtime.md
records it literally as "paint order (child slots)". A child list has
a definite order whether or not its children are ever drawn together,
so co-occurrence does not bear on it. The capture was the CHECK.
* The order is in the file anyway. paint_order_audit on GP_TITLE entry
11: derived == measured, 0 inverted pairs, 0 same-layer-key ties. The
glows and logos carry distinct T8aD keys (0xa100 < 0xa110), so the
file orders the halves statically, no capture involved.
I asked the question that started this iteration -- do the title and menu
orders have the same problem -- and the answer is that none of the three
does, for the same reason.
What survives is narrower and now recorded with numbers: how much of each
order its capture actually cross-checks. The title capture is stable (8
draws / 12 quads / 5 textures, identical in all five captured frames
across two logs) and confirms 7 of 24 positions; the menu capture is not
(texture 0x11C30000 present in frame 0, gone by frame 3); the splash
capture cannot cross-check its middle at all.
A counting trap worth the tool: count QUADS, not draws. The menu's draw 9
is indices=24 -- six quads batched from one texture. Counting draws reads
9 where 16 are on screen, and an earlier pass of this analysis briefly
"found" three quads for six declarations that way and concluded elements
were missing. They were batched.
METHOD: check what a "measured" value was measured FROM before reasoning
about its limits. The co-occurrence rule is real, and it is specific to
orders read from draw captures.

docs: the splash .prm measured -- and its paint order is a sequence, not depth
ui-prm-primitives recorded that where a .prm paints on a screen without a measured order is unsolved. For the developer splash it is now measured. Every frame opens with two full-screen draws before any sprite. The second is untextured in all 212 frames with a constant vertex colour of FF000000 -- opaque black -- matching palogo_eff0.prm's declaration exactly: kind 0x10, pivot (640,360) -> 1280x720, one keyframe, a = 255. So the splash backdrop is an opaque black full-screen quad from the bundle itself, painted behind every sprite, which is why a splash render needs --black rather than the default backdrop. Not a general rule, and said so: the measured main-menu order puts pteff02.prm at position 4 and pteff00.prm LAST, the latter being the screen-transition fade. And a correction to an existing row. measured_paint_order returns [0, 2, 4, 6, 1, 3, 5] for the splash, described as "the .prm, then all three glows, then the three logos". But the glows and the logos never appear in the same frame -- 0 overlapping frames in 235 -- and two elements that never co-occur have no observable relative depth. Between those halves the vector records the order they were SEEN IN, not a front-to-back relationship. That does not make the render wrong, and element 0 is a real depth observation since the .prm co-occurs with everything. But the type of the claim matters: reading the vector as depth invites compositing all seven elements at once, which is exactly what does not reproduce the screen. METHOD: two things that never co-occur have no observable relative order; when recording an order, note which pairs actually appeared together. |

re(ui): deliver the measured splash sequence the port has to author
The activation decision is code, and MISSION already says the port authors the sequence -- so the useful move is to hand over the sequence measured rather than chase the code. From the 235-frame draw capture, at 1 frame = 1/30 s (2 units/frame, 1 unit = 1/60 s, both settled in Q1): publisher: SQUARE ENIX logo f1-90 90 frames 3.00 s+ at 0.00 (gap, nothing drawn) f91-93 3 frames 0.10 s at 3.00 developer: both glows f94-115 22 frames 0.73 s at 3.10 developer: both logos f116-211 96 frames 3.20 s at 3.83 Three limits, stated with the numbers rather than after them. The capture opens with palogo_sqex already at a=255, so the publisher phase began before the window and 3.00 s is a FLOOR -- every "starts at" is relative to the capture, not to boot. palogo_anima and palogo_anima_eff get 0 draws in all 214 frames, so a third pair's phase is not in this measurement. And it is one capture, one run: the glow->logo switch being a single frame boundary with no overlap is a strong shape, but each duration is one sample. What is solid is the part that matters: the 0.73 s and 3.20 s phases are each within 2% of their element's declared span, so the durations are the bundle's own and only the ordering is authored. That is the difference between a port transcribing timing and inventing it. |

re(ui): re-establish selective activation by killing the alternative statically
Last iteration I withdrew "a bundle is a palette" because the evidence did not choose between selective activation within one bundle and two compositions shown in sequence. The alternative can be killed from the disc, which I had not tried. Hypothesis 2 needs a bundle declaring the GLOWS WITHOUT THE LOGOS. There is none. Every GP_TITLE entry carrying palogo elements: 10, 13 (publisher twins) palogo_eff0.prm, palogo_sqex, palogo_sqex_eff 11, 14 (developer twins) palogo_eff0.prm + all three logos + all three glows Four entries, and each developer entry declares the complete set of six. So whichever bundle was active across frames 94-211 -- entry 11, entry 14, or both in turn -- it declared the logos and the glows, while the game drew two sprites at a time in disjoint phases. Therefore only a subset of a bundle's elements is drawn at any moment, whatever the bundle-loading story is. The conclusion no longer depends on resolving how many bundles are involved, which is why the texture-base test's failure stopped mattering. So the claim is reinstated -- this time by eliminating the alternative rather than by assuming it away. What worked was not a better capture but asking what the competing hypothesis would REQUIRE on the disc and finding it absent. METHOD: a hypothesis that predicts an artefact can be killed by looking for the artefact, which is often far cheaper than measuring the behaviour. |

re(ui): withdraw the mechanism -- "palette" was an explanation, not a finding
Last iteration I wrote that a bundle is a palette whose elements are
selectively activated. The disjoint glow/logo phases have two
explanations and I asserted one:
1. one bundle, some elements run then others;
2. two bundle-loads shown in sequence (entries 11 and 14 are twins
declaring identical sprites).
The draw log's tex[base=...] looked like it would separate them. It does
not, and the control is in the same table:
publisher splash f1-90 0x11C30000, 0x10000000
glows f94-115 0x11C30000, 0x10000000
logos f116-211 0x11C30000, 0x10000000
The publisher splash is certainly a DIFFERENT bundle from the developer
splash, and it uses the same base. So 0x11C30000 is a reused upload slot,
not a bundle identity, and the test cannot choose between the two
hypotheses.
Survives: a bundle's declared elements are not what gets drawn.
palogo_anima and palogo_gamearts carry byte-identical keyframe times and
in the same run one is drawn 95 frames and the other none -- and
whichever twin was active declares both. The phases are strictly disjoint
(0 overlapping frames in 235).
Withdrawn: the mechanism. The practical consequence is unchanged --
compositing every element of a bundle does not reproduce what the game
shows over time -- but the why is not established and I stated it as
though it were.
What would separate them: a per-draw capture recording the bundle each
draw came from, or a file-IO log showing whether a second RATC entry is
read between frames 115 and 116.
METHOD: a shared resource address does not identify the resource's owner;
and state the mechanism as a separate claim from the observation, or the
weaker one inherits the stronger one's evidence.

re(ui): the sequencing survives refutation -- and a bundle is a palette
Two checks on last iteration's "sequential, not simultaneous" reading. First, the phases really are disjoint. If glows and logos ever shared a frame the claim would be wrong. Across all 235 captured frames the count of frames containing both is ZERO, and the switch is a single clean boundary -- f110-115 draw 1280x720 + 262x108 + 525x90, f116 onward 1280x720 + 243x86 + 499x72. Two sprites either side, no transition frame. Second, and larger: a third of the bundle is never drawn. Entry 11 declares three logo/glow pairs and only two appear. palogo_gamearts / _eff 95 / 22 frames palogo_seta / _eff 95 / 22 frames palogo_anima / _eff never palogo_anima declares the SAME keyframe times as palogo_gamearts. Two elements with byte-identical data, 95 frames and 0 frames in one run. Reach: the capture covers frames 1-214, so this is "never in the window". So a bundle is a palette, not a script. Its elements say what to draw and for how long; which of them run, and when each starts, is decided outside the placement data. That is the same conclusion the boot-order work reached from the other end -- the driver is code, not data -- now with a per-element measurement behind it. For the port, concretely: compositing every element of a bundle does not reproduce what the game shows over time. It is the right thing for a static screen that settles, and it is not a timeline. METHOD: two elements with identical data and different outcomes is the strongest possible evidence that the decision is elsewhere. |

re(ui): a group's duration is in the data, its start time is not
Tested whether the splash timeline, played, reproduces the capture -- the last gap in the animation model. Half of it does. Durations match. At 2 units/frame under the shifted reading, from the 235-frame draw capture of the developer splash: glows drawn f94-115 (22 frames = 44 units) declared ~0..45 = 45 97.8% logos drawn f116-211 (96 frames = 192 units) declared 15..210 = 195 98.5% Each element is on screen for its declared span to within 2%. Starts do not. Every glow declares the same times 15,30,45 and every logo the same 15,30,190,194,206,210, so on one clock they would overlap almost entirely -- and they do not overlap at all. The glows run 94-115 and the logos 116-211, strictly sequential, the logos starting the frame after the glows end. Fitting one origin needs f0 ~ 93.5 for gamearts_eff and ~103 for gamearts, about 19 units apart, and aligning one throws the other off by ~9 frames at both ends. The obvious candidate is refuted. parse_placements reads each group header as (element index, keyframe count) plus one undecoded LEAD-IN WORD -- exactly where a per-group start offset would live. It is 0x00000000 for all seven elements, glows and logos alike. Reach: not the keyframe times (identical within each family), not that word (zero), not declaration order (which interleaves logos and glows where the observed sequencing groups them), not the RATC child order. What remains is that the sequencing is code-driven, which agrees with what the boot-order work concluded independently. For the port: a group says how long an element animates and what it does, not when it starts relative to its neighbours. The observed order on the developer splash -- both glows, then both logos -- is measured for one screen, not a decoded rule, so the sequencing has to be authored. METHOD: when a model reproduces durations but not positions, the missing piece is an origin, not a rate. |

re(ui): a static composite is only meaningful for a screen that settles
The model's sharpest prediction, tested with its control. The draw log says that on the developer splash the _eff glows are drawn on frames 94-115 and the logos on 116-211, so at the moment the reference capture was taken EVERY glow is already finished -- including the two that have plateaus and which rest_plateau therefore renders visible. Suppressing them should help on the splashes and hurt where a screen genuinely settles. publisher splash +0.9604 -> +0.9982 +0.0377 developer splash +0.9659 -> +0.9980 +0.0321 title (control) +0.9500 -> +0.9480 -0.0020 main menu(control) +0.9460 -> +0.8544 -0.0916 EXTRAS (control) +0.9440 -> +0.8370 -0.1070 Both splashes jump to about 0.998; all three persistent screens get worse. The control is what makes this a finding rather than a coincidence: the same edit helps exactly where the model says it should and hurts exactly where it says it should not. So rest_plateau is not over-drawing in general -- it over-draws on TRANSIENT screens. A plateau mid-animation means the element is held at that point in the timeline, not that it is on screen once the screen has settled. Where a screen settles, the held pose IS the settled pose and the rule is measurably right. And that answers the question left open several iterations ago -- what "rest" means for a transient element. It does not mean anything: the splashes never rest. A static composite of them can match a chosen frame, and about 0.998 is what these captures' frame is worth, but the format does not answer a question the screen never poses. For the port: play the timeline for the two splashes, which the settled keyframe timing now supports, and composite statically for title, main menu and EXTRAS. METHOD: an edit that improves one set of cases is only interesting once you have shown it damages the cases where it should. |

re(ui): the structural case for last -- 2 293 of 2 305, checked disc-wide
The weakness in the rest-rule finding was that `last` had been SCORED on only two elements. It cannot be scored on more -- only two ambiguous elements sit on a screen with a live capture -- but the entry -> hold -> exit model makes a prediction that can be checked on all 2 305: what does each element's FINAL keyframe look like? final keyframe invisible (a = 0) 1 618 transient: gone at rest final keyframe visible, at max alpha 675 faded in and stopped final keyframe visible, BELOW max alpha 12 genuinely unclear Of the 687 that end visible, 472 have monotonically non-decreasing alpha -- a plain fade-in that stops, [0, 255] over two keyframes in the commonest case (pjex_eff.rat, pghud_speed_cut.t32) -- and another 203 end at their maximum after dipping. So `last` is structurally defensible for 2 293 of 2 305 (99.5 %), against a dwell rule that returns a mid-movement frame by construction. Observed correct for 2, structural for 675, model-consistent for 1 618, unclear for 12. The assumption carrying the 1 618 is stated rather than buried: that a plateau-less element's animation has finished by the time the screen is settled. The draw log establishes exactly this for the two splash glows (drawn frames 94-115, logos 116-211) and establishes nothing for the rest. Default still unchanged. The case is now observational, structural and model-based rather than two data points, but it would move 1 896 elements and the decision belongs with whoever owns the renderer. |

re(ui): why rest_plateau is right -- and last is right only for a transient
The shifted keyframe-time reading looked like it implied something simple: the final pose is reached at a definite time and nothing follows, so rest should just be the last keyframe and the plateau heuristic could go. Tested by applying it to EVERY element: title +0.9500 -> +0.6819 -0.2681 main menu +0.9460 -> +0.6416 -0.3044 EXTRAS +0.9440 -> +0.5745 -0.3695 publisher splash +0.9600 -> blank (zero variance, corr undefined) developer splash +0.9643 -> blank Refuted, and the failure supplies the model. A group is entry -> hold -> exit, and the exit is the screen's DISMISSAL. While a screen is displayed it has not reached its last keyframe; it is sitting at the hold. So rest_plateau is the correct primary rule, and the last keyframe is the post-exit state -- correct only once the screen is gone, which is why applying it everywhere blanks the splashes. This does not contradict the shifted reading. That reading says when each pose is reached; it says nothing about the group being played to completion while the screen is still up. The step between them was mine. And it explains why last wins for the two plateau-less elements: an element with no hold is a transient, it flashes and is over, and at any settled moment it is gone -- which is its last keyframe. The draw capture says the same independently: on the developer splash the _eff glows draw on frames 94-115 and the logos on 116-211, so the glows are already finished when the logos are up. Three independent observables -- animation timing, static composites, and the per-frame draw log -- now agree on one rule: plateau where there is one, last keyframe where there is not. METHOD: a blank render is a NaN correlation, not a low score, and that NaN was the strongest form of the result; and when a model predicts something the measurement refuses, suspect the step you supplied between them. |

re(ui): quantify what changing the rest rule would do disc-wide
The open question was whether "last keyframe" holds beyond the two
elements I could score against a capture. It cannot be scored disc-wide --
only two ambiguous elements sit on a screen with a live capture -- but the
blast radius can be measured, and it argues the same way.
genuinely ambiguous elements 2 305
the two rules AGREE on 409 (17.7 %)
they DIFFER on 1 896 (82.3 %)
dwell (current): invisible pose 1 711 (74.2 %), zero-scale 195 (8.5 %)
last : invisible pose 1 618 (70.2 %), zero-scale 43 (1.9 %)
Two things follow. It is not a marginal choice: the rules disagree on 82%
of the affected elements, so "either is fine" is not available. And the
current rule produces 4.5x more degenerate poses -- a zero-scale pose is
collapsed to nothing, i.e. an element's PRE-ROLL before it has grown in,
which is definitionally not a rest. 195 elements currently rest at a frame
they are only passing through, against 43 under last.
That is an argument from the data's own structure rather than from the two
captures, and it points the same direction.
Kept honest: it is indirect. Fewer degenerate results is not the same as
more correct results, and last still returns an invisible pose 70% of the
time -- right for a transient element, wrong for a persistent one. The
default stays put; the numbers are in HANDOFF for whoever decides.

re(ui): the rest fallback fires on 2 elements, and "last keyframe" wins there
Scored candidate rest-pose rules by rendering and correlating instead of
arguing, and both results correct something I had published.
First, the exposure. The guessing fallback is reached only by an element
that is plateau-less AND multi-keyframe -- a single-keyframe element
short-circuits at `match len { 1 => first }`. Per screen:
title (4) 24 elements 2 plateau-less 0 reach the fallback
main menu (5) 16 5 0
EXTRAS (6) 18 5 0
publisher splash (10) 3 2 1
developer splash (11) 7 2 1
So on the three screens the port cares most about, rest() never guesses.
That is why three different rules render builds 4/5/6 to identical
correlations -- the code is unreachable there, which I nearly read as
"the choice does not matter".
Second, where it does fire, the last keyframe is markedly better:
publisher splash dwell +0.9600 last +0.9982 maxalpha +0.9600
developer splash dwell +0.9643 last +0.9758 maxalpha +0.9643
That refutes my own earlier refutation. I had killed the last-keyframe
rule by arguing it makes palogo_anima_eff invisible while its two
siblings stay lit, which looked like an artefact. The capture says
otherwise: making it invisible is what improves the match. The sibling
symmetry was my expectation, not evidence.
Caveat kept in front: both captures are single frames of a transient
animation, so this fixes which pose matches THOSE frames, not which is
canonically at rest. Default unchanged -- better on both screens where it
fires and identical on the other three, but it would move 2 305 elements
disc-wide on two measurements. Reachable via SYLPHEED_REST_RULE=last.
Also confirmed: all 195 zero-scale rest poses are inside the corrected
2 305 ambiguous population; none is a single-keyframe element.
METHOD: score a rule where it can differ, or you measure nothing; and an
argument from symmetry is a prediction, not a refutation.

re(ui): refute my own fix for rest(), and correct the defect rate by 65%
Two corrections from one experiment.
A keyframe group is entry -> hold -> exit, and the exit ends invisible:
on the five port screens the final keyframe is invisible for 21/24
(title), 8/16 (main menu), 12/18 (EXTRAS), 2/3 and 6/7 (splashes). So the
screen as seen is the HOLD, which is why rest_plateau is the right
primary rule and why "rest = last keyframe" would empty every screen.
That suggested a fix: an element with no hold has no representative pose,
so draw nothing rather than guess an endpoint. Tested through compose's
visible mask and correlated against the live captures:
title +0.9500 -> +0.6839 -0.2661
main menu +0.9460 -> +0.9037 -0.0423
EXTRAS +0.9440 -> +0.9094 -0.0346
Refuted on all three, and the reason invalidates a number I published. An
element with a SINGLE keyframe has no adjacent pair, so the plateau test
marks it plateau-less -- but its one pose is unambiguously its rest.
Suppressing those removes backgrounds and full-screen layers, which is
the title's -0.27.
no plateau (as published) 3 807 (24.57 %)
... single-keyframe 1 502 trivially at rest, not a guess
genuinely ambiguous 2 305 (14.88 %)
So rest() guesses for 2 305 elements, not 3 807 -- the figure I gave the
port overstated the defect by 65%. Corrected in HANDOFF and the page.
METHOD: a predicate over adjacent PAIRS silently misclassifies a
one-element list; and acting on a claim is a better test of it than
re-reading it -- this flaw survived a census, a write-up and a handoff
row, and died the moment the rule was used to change a rendering.

re(ui): replicate the keyframe-time shift -- three elements, two screens
The case for reading +36 as "the time the NEXT pose is reached" rested on one element's fade-out shape, then on one element's hold duration. Both splash halves supply more, and they agree. element screen observed hold as decoded shifted palogo_gamearts developer splash 83 f 8 f 80 f palogo_seta developer splash 83 f 6 f 80 f palogo_sqex publisher splash >=77 f * 6 f 102 f * the capture opens mid-hold at frame 1, so 77 is a floor. The readings predict opposite structures. For palogo_gamearts, as decoded: hold 8f, in 80f, hold 2f, out 6f, out 2f -- an eighty-frame FADE-IN and a two-frame hold. Shifted: in 8f, hold 80f, out 2f, out 6f, out 2f. The capture shows an 83-frame hold and no fade-in at all. The elements that cannot discriminate are not contradicted: palogo_gamearts_eff observed in 7f / hold 7f / out 8f, and both readings give 8f phases -- with four blocks the shift only relabels which phase is which. So the glows, which is where Q1's linear law was measured, say nothing either way rather than arguing against. The decoder's default is still unchanged, and the reason is now articulated rather than assumed. The single thing opposing the shift is rest() on ptlogo_eff3, where the shifted reading makes the longest-dwell fallback return the bloom's 200% peak. That fallback is unsound whenever it runs -- it returns an endpoint of a movement, neither of which is held -- and checked: the shift does not fix it either. So the objection was never evidence about the times. Timing had three discriminating measurements; pose selection had a heuristic guessing. For the port: animation timing should use the shift; static composites are unaffected and the five screens' correlations stand. Classified measured, not decoded -- three elements in one screen family, not a disc-wide check. |

docs: one page saying how good the five screens actually are
The answers for the port's five screens were spread across a dozen documents and none of them said how good the result IS. Measured: screen build drawn corr vs capture alignment title 4 15/24 +0.9500 dy=0 dx=0 main menu 5 11/16 +0.9460 dy=0 dx=0 EXTRAS 6 13/18 +0.9440 dy=0 dx=0 publisher splash 10 2/3 +0.9600 dy=0 dx=0 developer splash 11 6/7 +0.9643 dy=0 dx=0 Every one aligns at exactly zero offset over a +/-2 px search in both axes, so placement and scale are right and the residual is tone and detail rather than geometry. The drawn/total counts are not slack. Each undrawn element has a reason already documented: kind & 0x4 ghost instances (4 on the title), .prm primitives off by default (2 per menu, 1 per splash), loop* animations off by default and off-screen at rest (2 per menu screen), and the 8AX name mismatch (1 per menu screen) whose art reaches the screen anyway via ptbase. 4+2+2+1 = 9, 2+2+1 = 5, 1. Nothing unexplained. The residual is ranked for a consumer: tone first (gamma 1.34-1.49, the game's own display ramp), then 8AX resolution, then one drawable paint-order tie on EXTRAS alone, then rotation-decoded-but-not-rendered which does not affect these five at rest. Reach stated: these are static composites at the resting pose against single frames, so nothing here speaks to animation, and a whole-frame correlation is a sanity figure rather than a per-element check. |

docs: the suite is heavy, not hung -- correcting my own "cannot terminate"
Last iteration I wrote that build-reborn test cannot finish in a working session, from having watched it run 3h26m. That was the stronger claim and I made it without measuring the work. Timing `mesh info` on each of the 166 .xpr containers with a 25 s cap: files scanned 166 exceeding 25 s 19 Hangar, 17 Stage_*, ptc_pack Stage_S02 to completion 144 s, rc = 0 Nothing hangs. Nineteen heavy containers at roughly two minutes each is about 45-60 minutes for one pass, before the 147 fast ones. The 3h26m observed was that hour of work running at a load average of 9-14 -- inflated by the two duplicate runs I had left going, which did not merely coexist with the slowness but multiplied it. The practical conclusion is unchanged and only the wording softens: an hour-scale suite is not an iteration-scale gate, and every "green" I reported from it this session was partial. But an hour-scale gate can be run deliberately, whereas a hung one cannot be run at all, so the distinction is worth having right. File list committed as reference data so the cost is attributable without re-scanning. METHOD: a slow thing observed under contention looks like a stuck thing; measure the work before choosing between "cannot finish" and "takes an hour". |

docs: the verification gate cannot terminate, and I left two runs going 4h
Two findings from checking whether last iteration's partial green had finished. It had not, and the reason matters for anyone using the gate. build-reborn test contains twin_pairs_do_not_share_a_buffer, which decodes every .xpr in hidden/resource3d -- 166 files, 1.4 GB -- through the full Xbg7Model anchoring path, and is NOT #[ignore]d. Its sibling in the same file walks the same 166 files and IS ignored as known-failing, which makes the binary's cost easy to underestimate. Measured: one instance accumulated 3h26m of CPU at 89% without finishing. So every "green run" reported in this corpus from a workspace or sylpheed-formats test is necessarily PARTIAL unless it says the suite terminated -- including the ones I reported this session. The honest form is the suite count and elapsed state, not the word "green". Not proposing to #[ignore] or subsample it: that changes what the suite asserts and is the project's call, not an audit side-effect. And the mess is mine. Two cargo test -p sylpheed-formats runs launched detached in earlier iterations never exited, because they were sitting in that test: pid 103375 4h12m elapsed child mesh_consistency_disc 3h26m CPU 89.3% pid 99965 4h39m elapsed child pak_idxd_disc 1h16m CPU 93.8% Load average 14.18 on 12 cores. Killed, after checking the legitimately running workspace suite and leaving it alone; load fell to 9.68. What this does NOT explain, because it is tempting: the session's emulator troubles. screenshot cost 0.49 s with both runaways live and the emulator stopped, against 10.8 s measured earlier with the emulator running. The 92x figure really was emulator contention; the runaways were a background tax on top. The black surface and the unreachable title stand as measured, with their own controls. METHOD: a detached job you never check can outlive many iterations -- setsid was added so a timeout could not kill them, which also means nothing does; and know whether your verification gate can terminate. |

docs: check that the docs' headline figures match their committed data
Nothing had ever verified that a number written in prose matches the reference data file committed beside it. The figure is written once from a run; the prose is edited around it afterwards and the data file is regenerated independently, so drift is silent. All 19 headline figures across four censuses -- the eff-bit census, the plateau census, the top-level rotation census and the eff-bit alpha test -- currently agree with their data files. The checker had to be numeric, and the first attempt is the reason it is a script rather than a grep: comparing strings reported almost every figure as a mismatch, because the data files write 14709 where the docs write "14 709" with a thin space, and the docs round 33.66 to 33.7. A consistency check that fails on formatting trains you to ignore it, so the tolerance is explicit: exact against the data, within 0.05 against the doc to allow rounding. Also ran the full disc-gated workspace suite (build-reborn test, which wires SYLPHEED_DISC -- without it the disc tests self-skip and green means almost nothing), covering this session's three decoder changes: rotation_deg on Keyframe, the scale-0 fix in blit/fill_quad, and the flags field on T8adImage. 122 passed / 0 failed across the four suites that had completed; the long disc-gated integration tests (records_roundtrip_disc, first_header_word_is_record0_hash) were still running and are not counted here. |

re(ui): premultiplied alpha refuted for bit 0x02; parking the field
A per-sprite premultiplied-vs-straight-alpha flag would matter a lot to a port and has a sharp static signature: premultiplied means RGB <= A everywhere. Over the 170 decoded GP_TITLE textures that pair to a flag word: bit SET n= 61 mean %(RGB>A) 55.52 median 52.52 bit clear n=109 mean %(RGB>A) 33.66 median 30.17 Premultiplied requires ~0% for the flagged group. Both groups are far from it and the flagged group violates MORE -- the opposite of the hypothesis. Refuted. What remains is a weak association: flagged sprites carry more bright-RGB/low-alpha pixels, which is what glow art looks like. But the best single threshold classifies 76.5% against a 64.1% base rate -- a 12-point lift with badly overlapping distributions. A tendency, not a rule, and reported with its base rate so it cannot read as more. Noted for whoever returns: "0x02 selects an additive blend" was refuted by blending those sprites additively and finding every measure worse against the capture -- but that ran through a title render since fixed twice (rest_plateau, and the 8AX background the composer drops). The refutation may well stand; it was measured through a renderer with known other errors, so it is worth one re-run if blit ever gains additive blending. Parking the field. Four candidate meanings are dead -- additive blend, eff name in both directions, transient element, premultiplied alpha -- none produced a positive account, and the bit blocks nothing: the port's screens composite at 0.947 correlation against a capture without it. The negative space and the sound attribution method (child order, not size) are written down so a later attempt starts here. METHOD: report a classifier's lift over its base rate; and park a field after N failed hypotheses, saying what was eliminated. |

re(ui): the eff-name implication for bit 0x02 is refuted disc-wide
Last iteration I killed the biconditional and reported that the one-way
reading survived: all 10 bit-set sprites on GP_TITLE build 4 are eff
names, so "bit set => eff name". Checked over the disc, that is false.
sprites with a resolvable preceding name 14 709
bit SET & name has 'eff' 2 338
bit SET & name lacks 'eff' 2 657 <-- counterexamples
bit clear & name has 'eff' 1 399
bit clear & name lacks 'eff' 8 315
P(eff | set) = 0.468
P(eff | clear) = 0.144
The implication fails more often than it holds. What survives is an
association -- 3.3x enrichment -- and build 4's 10/10 was a local naming
habit in an 18-element bundle, not a format rule.
The counterexamples are the useful part: pv_loading_ring0,
pv_loading_light0-3, pv_loading_line, px_bunk_line, px_top_extra. Rings,
glows, lights, thin lines -- effect-like artwork that does not carry the
eff naming convention. Consistent with the bit marking effect sprites by
authoring intent rather than by name, which is a description and not a
decode, and is labelled as such.
Names here come from the string immediately preceding each T8aD,
validated 17/18 on build 4 against the RATC child order; the single
mismatch is the known pteff04.t32 -> registered as 8AX case, so this is
the element (opt) name rather than the sprite's registered name. That
mismatch is itself an independent confirmation of the 8AX finding,
reached from the opposite direction.
METHOD: a pattern perfect on one screen can be near-chance on the disc;
and when an association survives a refuted implication, the
counterexamples are the finding.

re(ui): kill two candidate meanings for the T8aD 0x02 bit, and fix attribution
The bit at +0x04 was recorded as a real field with its meaning "not
diagnosed", noting ptlogo_back2eff is 0x8830 "despite its name". That note
rested on a size match -- and its size is ambiguous, which is the trap
this corpus already records.
First, a sound attribution. T8aD headers appear in the bundle in RATC
CHILD ORDER, verified on GP_TITLE build 4 against an independent property
-- each header's decoded dimensions versus the dimensions the named child
should have: 18 of 18 match, 0 mismatches. Two of those eighteen share a
size (ptlogo_back2eff and ptlogo_back2eff5, both 1133x280), so a size-keyed
lookup cannot separate them; ordering can. Index 12 is back2eff5 (0x8832,
bit set), index 14 is back2eff (0x8830, bit clear). The documented
counterexample is real and correctly attributed -- now on evidence.
Two candidate meanings tested and refuted:
bit <=> name contains "eff" REFUTED: ptlogo_back2eff is an eff
name with the bit clear. All 10
bit-set sprites are eff names, so
the implication holds one way only.
bit <=> the element is transient REFUTED: pteff03/pteff03a carry the
bit and run to t=250, ramping to
a=255 and holding.
Up close, the exception pair differs in two header words: +0x04
0x8832/0x8830 and +0x08 0x8083/0x8081 -- layer keys 32899 and 32897. They
are NOT duplicates: their alpha summaries agree to one decimal (4.5%
opaque, 86.7% clear, mean 19.3) but a pixel compare gives max abs diff 21.
Two renditions of one image at one size, which is why the summaries were
not trusted.
Still not diagnosed, and said so -- but the search space is two smaller
and the attribution beneath it is now sound.
METHOD: T8aD headers sit in child order, use that not the size; and
identical summary statistics are not identical data.

re: the GPU trace is compiled out of the release build -- both my guesses wrong
Last iteration left two candidates for why trace_gpu_stream produced no
file: the CLI flag not reaching the cvar, or BeginTracing failing
silently. Neither. Following the code instead of guessing:
BeginTracing only sets trace_state_ = kStreaming ("Streaming starts on
the next primary buffer execute"). The file is opened later, in
ExecutePrimaryBuffer, inside
#if XE_ENABLE_TRACE_WRITER_INSTRUMENTATION == 1
and trace_writer.h defines that as 0 under NDEBUG, 1 otherwise -- the
trace writer exists only in debug builds.
Confirmed against the binaries, with a control. The format string
"{:08X}_stream.xtr" lives only inside that guard:
build/bin/Linux/Release/xenia_canary 0 occurrences
build/bin/Linux/Debug/xenia_canary 1 occurrence
/sylph-home/re/canary-build/.../Release/... 0 <- what run-canary uses
The debug binary is the control: it proves the test finds the string when
it is present, so the release zero means something.
So trace_gpu_stream is a no-op in this container's emulator -- the cvar
parses, BeginTracing runs, and nothing can open a file. The kill -9 was
not the cause either, though it would have destroyed a trace had one
existed.
The route exists but is not cheap: a debug build with the writer compiled
in sits at build/bin/Linux/Debug/xenia_canary, 253 MB against Release's
18 MB, so a much slower boot plus a trace of every GPU packet on a disk
at 95%. Recorded as available rather than attempted -- what it would
confirm, the DC_LUT write, is already a well-supported inference, and the
cost is out of proportion to the gain.
METHOD: a cvar existing does not mean the feature is compiled in; and
test a compile-time gate against the binary, with a control.

re: GPU trace attempt produced nothing -- and the config dump is not the flags
Tried to turn the gamma-ramp inference into a direct observation. canary's trace_gpu_stream records gamma ramps as their own command type (kGammaRamp, index 11 in TraceCommandType), so a boot trace should show the write. Two bounded runs produced NO trace file at all -- nothing under the prefix, no .xtr anywhere, no scratch/gpu/. Bounded deliberately: the disk is at 95% (50 GiB free) and a trace of all GPU packets during boot includes video decode, so the runner carried its own watchdog that killed the emulator the moment output passed a 2 GiB cap. It never fired -- there was nothing to cap -- and disk stayed at 95% throughout. Bounding from inside cost nothing and removed any need to gamble on how coarsely I could poll. What the attempt did establish. BeginTracing() runs at GPU init when the cvar is set (graphics_system.cc:237), but EndTracing() runs only from GraphicsSystem::Shutdown() -- so the kill -9 this session has used routinely can never finalise a trace. The second run was stopped with SIGTERM and exited cleanly; still no file, so that is not the whole story. Two candidates remain unseparated: the CLI flag not reaching the cvar, or BeginTracing failing silently. The next run removes the ambiguity by setting trace_gpu_stream in the config FILE instead. And a trap I nearly fell into. The startup config dump showed trace_gpu_stream = false after I passed --trace_gpu_stream=true, which reads as "flag ignored". It is not evidence either way: the gamma run passed --log_mask=12 --log_level=3, its dump printed log_mask = 0 and log_level = 2, and Kernel Debug logging was demonstrably ON -- that run is where VdGetCurrentDisplayGamma was captured. The dump reflects the config file and can neither confirm nor refute a command-line override. (It does not undo the earlier user_language conclusion: absence of a NAME from the dump still shows a cvar is unregistered.) The gamma-ramp write therefore remains an inference, unchanged. |

re(ui): close the gamma chain from canary's defaults -- the game writes a ramp
Continues the previous iteration, where the game was measured calling VdGetCurrentDisplayGamma at video init. The remaining link -- does it then WRITE the ramp -- is a GPU register operation (XE_GPU_REG_DC_LUT_RW_INDEX in CommandProcessor::WriteRegister), unlogged and invisible to kernel logging. Two facts from the source close it without instrumenting. 1. The swap-path gamma stage is a PURE LUT. apply_gamma_table.xesli is the whole transform: index by input*255, fetch from a 256-entry ramp buffer, output. No sRGB encode, no second transfer function. 2. The table DEFAULTS TO IDENTITY. CommandProcessor::Initialize fills it with value = i * 0x3FF / 0xFF, and its own comment says the linear default is "what games set when starting with the sRGB (return value 1) VdGetCurrentDisplayGamma". An unwritten ramp is a no-op. So the only transform is a LUT, the LUT is identity unless written, the game queries the display gamma at init, and the capture differs from our composite by gamma 1.34-1.49 -- which identity cannot produce. The guest wrote a non-identity ramp. Labelled an inference, with its weak joint named: it assumes our composite reproduces the PRE-RAMP framebuffer, which it does not exactly. What carries it is the shape -- a systematic ~1.4 fitted on flat patches across three screens is not a compositor bug. The obvious alternative, a fixed sRGB stage in the presenter, fits neither direction: an encode (^0.45) brightens and we measured darkening; a decode (^2.2) darkens far more than 1.4. Direct observation remains available and cheap, and needs the emulator only to boot: a GPU trace records gamma ramps as their own command type, or one log line at the DC_LUT register write would settle it outright. Not done. METHOD: a default value is evidence; and name the weak joint of an inference in the same breath as the conclusion. |

Last iteration's corrected experiment, run. Boot with --log_mask=12 --log_level=3 (Kernel logging on, Cpu/Gpu off), which changes nothing about the output and so cannot perturb the capture harness the way the gamma-cvar experiment would have. VdGetCurrentDisplayGamma is called once, at video init: d> VdGetSystemCommandBuffer(701CF830, 701CF804) d> VdGetCurrentDisplayGamma(701CE1F8(00000000), 701CE1F0(0)) d> VdSetDisplayMode(40000000) d> VdGetCurrentDisplayInformation(701CF110) The control is in the same log: 359 VdRetrainEDRAM and 358 VdGetSystemCommandBuffer lines, so an absent call would have been visible. Per the export's own comment the returned type is "used in D3D SetGammaRamp/SetPWLGamma" -- the game asks the question a ramp-builder asks, at the moment one would ask it. Still open, and stated: whether it then WRITES the ramp, and whether the measured gamma 1.34-1.49 is that ramp. The write is a GPU register operation (DC_LUT), invisible to kernel logging; a GPU trace records gamma ramps as a command type (TraceWriter::WriteGammaRamp), which is where to look next. Worth its own METHOD line: this had been parked behind "needs the emulator to reach a menu" for several iterations, and it needed the emulator only to BOOT -- video init happens in the first seconds. A blocker that stops one experiment does not stop every experiment in the same area. |

re(ui): the gamma confound is refuted from source -- canary applies none of its own
I had parked the tone-curve finding behind "this may be the emulator, not the game: canary applies kernel_display_gamma_type = 2 (BT.709) on output", with a planned run setting it to 0 and re-fitting. Reading the source kills both the confound and the experiment. VdGetCurrentDisplayGamma_entry is a kStub GETTER the guest calls (xboxkrnl_video.cc). Its own comment: "Used in D3D SetGammaRamp/ SetPWLGamma to adjust the ramp for the display." The cvar is a value REPORTED TO THE GAME, which then builds its own ramp. Canary's role is downstream: the guest writes DC_LUT, command_processor.cc reads it into gamma_ramp_256_entry_table_, and the swap path applies it via swap_apply_gamma_pipeline_layout with apply_gamma_table.ps / apply_gamma_pwl.ps compiled in. So there is no emulator-side BT.709 post-process to subtract, and any gamma in a captured frame is a ramp the game installed. What is NOT established, and the reach is stated: that this game installs a ramp at all, or that the measured 1.34-1.49 is it. The run logs cannot say -- kernel exports log at Debug and this harness masks Kernel logging (log_mask = 13, per boot_menu.sh's own comment), so their silence is guaranteed regardless of what the game did. The planned experiment was wrong in design: changing the cvar changes what the GUEST is told and therefore which ramp the GAME builds, so it could never isolate a stage that does not exist -- and it perturbs the capture harness, since skip_intro classifies movie-vs-static on an absolute rmse threshold that a brighter frame biases. The right run changes nothing about the output: LOG_MASK=12 LOG_LEVEL=3 and look for the call and the DC_LUT writes. Also for the port: the ramp depends on the display type the game is told, and canary hard-codes TV/BT.709 where hardware uses a console setting. So this is a display profile, not a fixed property of the game. METHOD: read what a cvar does before building an experiment around it; and an absence in a log is only evidence if the log would have shown it. |

re(ui): settle 8AX vs ptbase statically -- the game draws the full-res one
I had parked this as "needs a per-draw capture recording texture base addresses". It did not. 8AX (1280x720) and ptbase (640x360 at 200%) are the SAME artwork at two resolutions, which is exactly why comparing either against a capture is inconclusive -- and why comparing their DIFFERENCE is not. Compute 8AX - upscale(ptbase), the detail only 8AX has, and ask whether the capture contains it. Both candidates are first mapped into the capture's tone domain with the measured gamma; without that the residual is dominated by the tone difference and the test is blind. main menu corr +0.0475 controls +0.0032 shift, -0.0075 flip 68% of ceiling title corr +0.0634 controls +0.0095 shift, +0.0086 flip 68% of ceiling Two independent screens, both at 68% of the theoretical ceiling (sd of the 8AX-only detail over sd of the capture residual), 7-15x their matched controls. The controls preserve spatial correlation and destroy only alignment, so they are what "no signal" looks like. So the recommendation changes: resolve the name and draw 8AX at 1:1. Upscaling ptbase 2x is wrong, not merely softer. Still do not draw both -- an opaque layer over an identical one costs fill and hides later changes, and ptbase's element is the one carrying the keyframes, so a consumer needs its timing with 8AX's pixels. Also recorded and withdrawn: a cruder pixel-pair test gave 0.00-0.72 for upscales, 0.98 native and 1.01 for the capture -- apparently decisive. Additive noise raises both terms of that ratio equally and drives any value toward 1; fitting a noise term, both "native + noise" and "bilinear + noise" reproduce the observed numbers. The conclusion is right, that test does not establish it, and it is in REFUTED because the number looks conclusive and is not. Not shown: whether ptbase is also drawn underneath. 8AX is ~86% opaque and carries the same art, so it would hide it either way. |

docs: the UI decode's own evidence images were unreachable -- 11 links repaired
The brief's rule is to commit reference data beside the finding so the port can be built without a disc. Nothing had ever checked that the docs' cited artifacts actually exist. doc_link_check.py walks every markdown file under docs/, resolves each relative link, and reports targets that are missing -- and separately targets that resolve to a ZERO-BYTE file, which looks fine in any listing. links resolving 1038 -> 1049 missing targets 16 -> 5 empty targets 0 -> 0 +11 resolving and -11 missing against 11 edits: the counts pair, which is the confirmation the pass did what it claimed and touched nothing else. Two of the sixteen were the evidence for the UI layout decode itself. structures/ui-rat-layout.md is what the port is built on, and its two figures -- backing "the tutorial PAUSE menu rebuilds pixel-accurately from its sprites" and "the same method reproduces the main menu" -- were written as captures/ui-layout/... from a file in structures/, one directory too shallow. The headline evidence for the decode could not be opened from its own document. Eleven links had the wrong relative depth with the target present. Each was rewritten only where exactly one candidate path resolved, so nothing was guessed; the first pass left three alone because equivalent spellings (captures/../captures/x) failed to collapse, and a second pass normalised them. Five remain genuinely absent and are left rather than invented: two point at MEMORY.md outside the repo, one at a header in the separate xenia-canary-native tree, and two name documents that were never written (weapon-datasheet-runtime.md, canary-build-verified-env-confound.md). None is port-relevant. A missing document is a different problem from a bad path and is not something a link fix should paper over. |

re: the port was still being told SE audio is undecodable -- it is not
A resolve-check on HANDOFF's own rows. Q8 read "SE audio is undecodable
from the disc -- no XACT container exists anywhere". menu-audio-cues.md
retracted exactly that ("### Retracting 'cannot be extracted'") and
locates three cues in Static.slb that decode to PCM: d-pad move 0x1ec0
(4 packets), (B) back 0x0ec0 (2), (A) confirm 0x5d6c0 (6), all mono
48 kHz. The retraction landed in docs/re/ and the page the port reads
kept the superseded text -- the fourth time in this corpus.
Writing the rule down has not worked, so there is a tool now.
handoff_lint.py flags every HANDOFF line making a strong negative claim
that links a doc containing retraction language. First run: found the Q8
row, plus one benign false positive (Q3 links a doc whose retraction is
about a sprite count, not about the tie-break -- checked, and HANDOFF
repeats none of the retracted figures). The lint also caught its own bug
first: it reported existing docs as missing because it joined a guessed
repo root, so it now resolves links relative to the file as markdown does.
Separately, EXTRAS's paint-order risk narrows twice more. Of its 15 tied
pairs only 2 overlap, and of those, ptloop01 x ptloop02 are loop*
animations compose skips by default -- so exactly ONE tie can be drawn:
ptframe3 x ptframe4, overlapping 102x132 px. Against live-extras.png that
contested region correlates +0.9622, better than the whole frame (+0.9440)
and inside the range of regions where order cannot matter (+0.8502 /
+0.9903). Consistent with our order, not proof: correlation cannot see a
swap between locally similar art.
15 -> 2 -> 1 -> consistent is now the whole paint-order risk on the five
screens, and HANDOFF says so.

re(ui): the paint-order tie-break is undecodable from the bundle
Q3 was delivered as "decoded: a u16 layer key at +0x0A". The audit last
iteration showed the key does not fully order a screen -- elements
sharing a key are tied, and on the title that tie-break decides two total
occlusions. This searches for what breaks the tie, and closes it as a
negative with reach.
The game paints the five tied ptlogo_back2eff glows in the order
eff1, eff2, eff5, eff3, eff4. Three static structures were searched:
1. The declaration table. Entries 14-18 are byte-identical apart from the
pivot, which is only half the sprite's own size.
2. The T8aD headers. All five carry identical +0x04 (0x8832) and
identical +0x08/+0x0A (32899, the key itself), differing only in
position and tile count. Searched exhaustively -- every offset
0x00-0x7f, u8/u16/u32, ascending and descending:
fields sorting to the MEASURED order: 0
fields sorting to the DECLARATION order (control): 64
The control is the point: 64 fields can be found that reproduce a
known ordering, so the scan finds ordering fields when they exist. It
finds none for the order the game uses.
3. The RATC child order -- a genuinely different permutation on other
screens -- gives eff1..eff5 here, declaration order again.
All three static orderings give eff1..eff5; the game gives eff1,2,5,3,4.
That agrees with ui-screen-runtime's conclusion from the other direction:
the game builds a reordered child list at load time and paints that.
Q3 now reads honestly: the layer key is decoded and orders 4 of the 5
measured bundles exactly; the tie-break within a key is undecodable, and
a consumer must use a measured order or accept declaration index as an
arbitrary stand-in. The port's exposure remains 2 overlapping tied pairs
on EXTRAS.
METHOD: an exhaustive field search needs a positive control, or "found
nothing" is worthless.

re(ui): measure the paint-order hedge -- exact on 4 of 5, and bound the rest
`compose` claimed the derived paint order "reproduces both measured orders up to ties". That sentence was never measured and was stale by one: there are three measured orders, not two. examples/paint_order_audit.rs checks it. main menu (entries 5, 8) derived == measured 0 inverted pairs developer splash (11, 14) derived == measured 0 inverted pairs title (entry 4) DIFFERS 8, all same-key ties So the claim holds and the exception is entirely ties -- but two of those ties are total occlusions, not near-misses. The tied family is the five ptlogo_back2eff glows (key 32899); back2eff5 is 1133x280 and FULLY CONTAINS back2eff3 (82,824 px^2 = 100% of the smaller) and back2eff4 (152,047 px^2 = 100%). Derived paints it on top of two glows it entirely covers; the game paints it underneath. A tie-break by declaration index can therefore be wrong by a whole layer. The title itself is unaffected -- it has a measured order. The port's actual exposure, per screen: title, main menu and developer splash all use MEASURED orders; the publisher splash is derived but has ZERO ties, so it is fully determined; EXTRAS is derived with 15 tied pairs of which only 2 OVERLAP. Two element pairs on one screen is the whole risk, and that is what HANDOFF now says -- not the raw 15, which would have overstated it 7x. Reach stated: this compares the derived order against orders measured from the game, not an independent derivation, so where no measured order exists only the tie exposure can be checked. Overlap uses pivot*2 as the element size at its resting placement. Stale comment in compose corrected. METHOD: a hedge in a code comment is an unmeasured claim; and count the cases that can bite, not the ones that match the pattern. |

re: a title negative that survives its own cross-check
Three earlier "the title never appears" claims came from instruments later found broken -- a stale pixel oracle, a 41 s sampling interval, a freezing stream. This one carries its own evidence. title_probe_xchecked.py restarts its capture stream every 30 s AND prints its reading beside an independent `import` grab every 60 s: 1851 frames in 560.2 s = 3.30 fps cross-checks 9, disagreements 1 max glyph 0 t= 62s stream 6.05 | import 0.07 disagree (a fade, logos mid-transition) t=123s stream 7.40 | import 7.49 agree t=183s stream 8.18 | import 8.29 agree t=243s stream 0.23 | import 0.10 agree t=311s stream 89.68 | import 89.51 agree t=371s stream 80.97 | import 81.58 agree t=426s stream 117.43 | import 117.72 agree t=487s stream 77.71 | import 76.25 agree t=546s stream 70.43 | import 70.55 agree Eight of nine agree within 2%, fps held at 3.30 with no collapse to 1.60, and the surface moved through dark and bright phases. So the frames were live: over 560 continuous seconds from launch, sampled 3.3 times a second, the interactive title's green (A) plate never appears while the game renders throughout. The final frame correlates 0.0145 / -0.0047 / 0.0102 with our title / main menu / EXTRAS renders -- attract-movie content, not a UI screen. Why remains unknown. live-title-press-a.png with its 753 glyph pixels proves the title was reachable from this container on 2026-08-28, and clearing the shader cache fixed the black surface but not this. The two emulator-side questions (gamma control, 8AX vs ptbase) are therefore blocked on a characterised failure rather than a suspicion. Neither blocks the five menu screens, so I am returning to static work; the probe is committed for whoever picks it up. METHOD: a probe that cross-checks itself turns "no result" into a result. |

re: the fast probe stalls -- its own dense negatives are withdrawn
Cross-checked the instrument built last iteration against an independent grabber while both watched the same screen, and it fails. A single long-lived ffmpeg x11grab stream degrades and then freezes: 862 frames in 540.1 s = 1.60 fps (it starts at 3.98) t=450/480/510/540 s: surface mean 5.21, identical every time At that same moment `import` read surface mean 125.65, and a freshly started ffmpeg stream read 122.43 -- agreeing with import to 3%. So the acquisition was broken, not the analysis: the stream replayed a stale frame while the screen was 24x brighter. That withdraws last iteration's headline. "2391 frames over 600 s from t=0, max glyph 0" cannot distinguish "the title never appeared" from "the stream froze early and repeated one frame 2391 times". Its 3.98 fps was measured over the first 20 s, before the degradation. Sample count is not coverage unless the samples are known independent. Fixed: the stream is now torn down and restarted every 30 s. Startup is ~0.3 s, cheap against the title's window, and it guarantees live frames. Separately, the cache hypothesis was tested and is SUPPORTED. cache, cache0, cache1, cache_host moved aside (to /tmp/xenia-cache-aside, not deleted) and the surface renders again: import reads mean 54.8 and 68.6 with 100% non-black warm content, against 0.07 and 0.08% non-black in the black run; 773 of 862 probe frames had >2% non-black. One run each side and many kill -9s before the black one, so it is supported, not proven -- the old caches are kept for reproduction. Still no title, but that number now comes from a stalling probe and establishes nothing either way. METHOD: validating a probe on static images tests its analysis, not its acquisition -- cross-check against an independent grabber during a run. |

re: the game surface is rendering BLACK -- check that before explaining absences
The named experiment was to attach the fast probe at t=0 so the boot title could not be missed. Done, default config, English: 2391 frames in 600.4 s = 3.98 fps; max glyph 0; hits 0 Ten minutes sampled four times a second FROM LAUNCH, no green-(A) glyph. So "the plate only shows in an early boot window I keep missing" is mine and refuted -- the third explanation refuted in three iterations. Then the check that should have come first. Splitting the raw root grab into bands: y 0- 44 (GTK menu bar) 100.00% non-black mean 210.50 y 45-719 (game surface) 0.08% non-black mean 0.07 The game is rendering black, reproducibly across back-to-back samples, while the guest is alive and polling input (XamInputGetKeystrokeEx past 1201 calls) and MEM-WATCH keeps reporting. The crop and every pixel oracle were correct; there was nothing on the surface to detect. What this does NOT do is retroactively explain the earlier failures, and claiming so would be the fourth over-reach in a row. Those runs had content: run 2 sampled mean 33.1, run 3's classifier measured real frame-to-frame rmse, the gamma_type=0 run measured mean 122.8. The failure mode CHANGED over the session; black is the newest and worst. Hypothesis for the regression, untested: canary's shader/pipeline cache is 47 MB and was last written 23:49 on Aug 28, during the failed runs, and this session has kill -9'd the emulator repeatedly. The test is to move cache* aside and boot again -- one line and one run, not done. Two METHOD lines: ask whether the screen is drawing anything before explaining why a feature of it is missing; and a newly found fault does not retroactively explain older failures. |

re: build the fast probe -- and it refutes the diagnosis that motivated it
Last iteration I blamed four failed runs on the probe sampling every ~41 s, slower than the title screen lasts, and withdrew three earlier conclusions on that basis. Building the fix tested the claim and killed it. The speedup is real and control-verified. One long-lived ffmpeg x11grab stream, raw RGB, glyph counted in numpy -- no per-sample process startup, no PNG encode, no convert -crop: wrapper `screenshot` 3.98 s per sample (emulator running) import -window root -> PPM 1.20 s long-lived x11grab stream 0.29 s 13.7x The counter is byte-identical to is_title.py: 753 on the committed title capture, 327 on the main menu. Pointed at a running game it says the opposite of what I expected: 332 frames in 85.3 s = 3.89 fps; max glyph 0 1674 frames in 420.0 s = 3.99 fps; max glyph 0 1674 consecutive samples over seven unbroken minutes, four per second, zero green-(A) pixels. Sampling rate was a real defect that happened not to be the cause. So "neither locale reaches the interactive title without a pad press" -- withdrawn last iteration for want of evidence -- is reinstated, now as a dense measurement, with its reach stated: a MID-RUN window only, silent about the boot title. Leading hypothesis, unconfirmed: the PRESS (A) plate appears only in the boot title window and the attract loop's title carries none, which is exactly what title_states_capture.sh was written to test. The experiment is to start the fast probe from t=0 rather than attach to a run already in progress. METHOD: fixing the instrument is how you test the explanation that blamed it -- a plausible mechanism is a hypothesis, and the fix is its experiment, not its proof. |

re: the boot harness was blinking slower than the title -- diagnosed
Four consecutive runs failed to reach the interactive title, across two locales, two launch paths and two display-gamma settings. I attributed it in turn to a stale oracle, to the locale, and to the attract loop. It was none of those. one `screenshot` call, emulator running: 10.8 s one `screenshot` call, emulator killed: 0.117 s 92x, measured at a 1-minute load average of 1.80 -- so it is contention with the emulator through the X server, not background load. skip_intro.sh takes two grabs per iteration plus a numpy import, giving a median sampling interval of 41 s in the last run (38/82/41/20/30/30/35/ 47/46/45/44/43/21/19). The title lasts "a few seconds" before the attract loop reclaims it -- wait_title.sh's own header says so. The harness was sampling slower than the event it was waiting for. That also explains why runs at 16:43-18:05 the same day succeeded. Withdrawn as CAUSES, though the observations stand: "the JP run never reaches the interactive title", "neither locale reaches it without a pad press", and "the game sat in the attract loop for 604 s". The English control did control for locale -- it just shared the same defect. Also recorded: I set kernel_display_gamma_type = 0 for the gamma control run, which brightens the frame (mid-attract mean 122.8 vs 52.5/82.8 at type 2) -- and skip_intro classifies movie-vs-static on an ABSOLUTE rmse threshold, so the gamma change biased the very classifier the run depended on. Changing a display setting and a capture behaviour in one run confounds both. Config restored to type 2. The fix is not applied: make the probe cheap enough to outpace the title window (small region, no convert round trip, one long-lived process). Every remaining emulator-side question is waiting on that. |

re(ui): put a number on the render-vs-capture tone difference
Closes an observation I left dangling last iteration ("the capture is ~4x
darker than the render") and puts a figure on the ❔ INDEX's texture row
already carried: exact gamma/sRGB fidelity untested because a hue
comparison cannot see it.
Geometry first: cross-correlating the main-menu capture against our
render over +/-6 px puts the best alignment at exactly dy=0 dx=0,
correlation 0.9466. Only the tone differs.
Two methods failed before one worked, and both failures are recorded.
Three dark patches gave "4x darker" -- the whole-frame best linear scale
is 0.914, so three patches from one region are not a transfer curve. A
pixel-wise fit over 854,685 pixels then produced a NON-MONOTONIC transfer
(render 96-127 mapping brighter than render 128-159) with mean abs error
10-14 for every candidate model. That is edge misalignment, not a tone
curve: at correlation 0.947 a bright pixel routinely lands on a dark one.
Flat patches fix it -- 16x16 blocks with std < 8 in BOTH images, a
threshold chosen from the counts (0/83/404/1055/1788 at std<3/5/8/12/20):
main menu 404 patches gamma 1.491 err 0.28 (best linear 0.276, 0.34)
EXTRAS 382 patches gamma 1.493 err 0.22 (best linear 0.273, 0.28)
title 506 patches gamma 1.338 err 1.08 (best linear 0.842, 9.02)
Reach, stated because it is narrow: those patches span only render values
~0-60, where gamma and a plain scale are nearly indistinguishable -- the
two menus decide nothing (0.28 vs 0.34, 0.22 vs 0.28) and only the title
separates them. Nothing constrains midtones or highlights.
The held-out control FAILED TO DISCRIMINATE and is reported as such: the
splash's 2918 flat patches are pure black (render 0-4), so every model
scores ~0.00. That is a test with no power, not corroboration.
Confound left open: this compares our composite to what canary DISPLAYS,
and canary applies kernel_display_gamma_type = 2 (BT.709). The exponent
may be its output stage. The discriminating run -- set it to 0, recapture,
refit -- needs one emulator session reaching the main menu and was not
done.
Classified measured, not decoded; HANDOFF says plainly that a port
applying it is authoring.

re(ui): a full-screen element is dropped on three port screens -- do not "fix" it
Audited what `screen render` silently omits on the port's five screens,
since an element the game draws but we skip is the one defect class the
port agent has actually hit. Everything is accounted for -- kind & 0x4
ghost instances, .prm primitives, loop* animations -- except pteff04.t32
on the title and pteff05.t32 on both menus. Those are kind 0x0, one
keyframe, rest a=255, pivot (640,360): full-screen and opaque.
Cause: the element declares pteff05.t32, but the T8aD behind its `opt `
link is registered under the name 8AX, so build.sprites.get() misses and
compose hits a silent continue. Bytes at 0x0e2035 of GP_TITLE entry 5:
opt ... 70 74 65 66 66 30 35 2e 74 33 32 00 38 41 58 54 38 61 44
p t e f f 0 5 . t 3 2 \0 8 A X T 8 a D
8AX is 1280x720 and present in all six title-family bundles; it is a
sprite in builds 4/5/6 and never an element.
It does not currently show, and that is the useful half. ptbase.t32 is
640x360 drawn at 200% and carries THE SAME ARTWORK: its 2x upscale
differs from 8AX by mean abs diff 2.05 (max 80), and our rendered
background is pixel-identical to 8AX in every patch sampled. So resolving
the name and drawing it in addition would double-draw an opaque
full-screen layer -- invisible as a doubling, which is worse than a
visible bug. Written into HANDOFF as a do-not-do.
The free win, offered and not taken: use 8AX at 1:1 and drop ptbase
instead of upscaling a half-res copy. That is a rendering choice and
ptbase's element carries the keyframes, so it is the port's call.
Not established: which of the two the game actually draws. Both carry the
same art, so pixels cannot separate them; it needs a per-draw capture
recording texture base addresses, since the two differ in size.

re: the title capture is not reachable here either; stopping this line
Run 3 used the proven path rather than my own probe: launched exactly as
boot_menu.sh does (DISPLAY=:98, --apu=sdl, /dev/shm/xenia_* cleared, the
existing profile signed in) and drove skip_intro.sh, the detector that is
documented to work and that is stricter than mine (glyph >= 800 AND a
static frame).
It classified every one of 20 samples over 604 s as "movie", waited them
all out, and timed out. A direct check at 604 s says it was right: zero
green-glyph pixels, screen_id = other, warm mean (69,53,40), correlation
0.09 with build 7. The game really was playing attract movies for ten
minutes.
Three runs, two locales, two launch paths, ~35 minutes of emulator time,
no interactive title. Either the attract loop is far longer than the

Two iterations framed the JP title capture as possibly locale-specific. It is not. Same flags, same oracle, English locale: 75 samples over 734 s, every one glyph = 0. The English boot does not present the interactive title either. Canary was alive throughout, polling XamInputGetKeystrokeEx (1801 calls); the frame at 734 s has content but correlates 0.15 with build 4's render and 0.05 with the main menu -- an attract-movie frame, not title art. So neither locale reaches the interactive title in ~12 minutes without a pad press. What is actually untested is the pad: pad.py and nav_to_flight.sh exist, and title_states_capture.sh reaches title states with a flag set this probe did not replicate (--log_ui_draws --ui_draw_capture_frames, plus xdotool window focus). It is a capture problem, not a locale one. MISSION.md updated. Also resolved a caveat I had given the port agent without checking it: "rotation is decoded but not rendered" does NOT affect their five screens at rest. Title, main menu, EXTRAS and both splash halves have ZERO top-level elements with a non-zero rotation. The only rotations on any of them are the title's two nested ptloop records (r = 30 and -45), and at rest those sit at x = 1521 and x = -839 -- a 399-wide sprite entirely off both edges of a 1280 screen. The caveat now applies only to animating the title build-in, where the sweeps cross the screen rotated. Two METHOD lines: run the control before theorising about the difference, and log every sample so a failure is a measurement rather than a silence. Emulator stopped, lock cleared, locale English. |

re: fix wait_title.sh's stale oracle; the JP title still is not reached
Last iteration's "never reached the title in 787 s" was a broken tool reporting on the world. wait_title.sh was still sampling the single pixel (625,618) that is_title.py had already been written to replace -- its docstring says why: a 1280x720 coordinate sampled against the 1279x675 game surface, so it always reads the copyright line. The replacement sat in the same directory. wait_title.sh now delegates to it. is_title.py passes its own controls before being trusted here: 753 green-glyph pixels on the committed English title capture, 327 on the main menu, threshold 400. Re-ran with the working oracle and the profile flag the English captures use. The game STILL did not present the interactive title -- but that is now a measurement rather than an artefact: not one frame showed a single green-(A) glyph pixel, and content correlation against either build-7 render never exceeded 0.22. Canary was alive and polling XamInputGetKeystrokeEx (601 calls), sitting in the attract movie. So the open question narrowed again, and is written into MISSION.md: whether the attract loop returns to the INTERACTIVE title without a pad press. title_states_capture.sh claims it does on the English boot with no pad input; if that holds, the difference is the locale. Nothing decided about the keyframe-time association or the rest() rule. Emulator stopped, lock cleared, locale restored to English. |

re: the JP-locale capture is not blocked -- I stopped one grep too early
Last iteration I wrote into MISSION.md that a Japanese-locale capture is impossible here, because user_language is DECLARE_int32 at four call sites with no DEFINE and no entry in xenia-canary.config.toml. That is true, and it was not the question. The language is PERSISTED: kernel_state.cc builds XConfig over <storage_root>/xconfig.settings, SetDefaults() only supplies a value when the file has none, and the file is writable. Checking where a setting is stored rather than where it is configured turned "blocked, needs a human decision" into a two-line edit. Withdrawn from MISSION.md; METHOD and REFUTED lines added. The field is located from struct landmarks rather than a hard-coded offset, and the check re-runs on every invocation so it fails loudly if the layout moves: music_volume 0.7f at User+449 -> BE float at 2727 -> User base 0x8e6 language at User+44 -> reads 1 (kEnglish) at 0x912 country at User+64 -> reads 103 (US) at 0x926 XLanguage::kJapanese = 2 (xbox.h:307). set_console_language.py wraps it with a backup and a --restore. The capture itself is still NOT taken, for a smaller reason than I claimed. A run with the locale set to Japanese booted fine but never reached the title in 787 s: wait_title.sh's green-(A) oracle never fired and burst-sampling found no frame correlating above 0.18 with either build-7 render -- the run sat in the attract loop. So it needs a longer or pad-driven run, not a rebuilt emulator. Emulator stopped, lock cleared, locale restored to English. Nothing is decided about the keyframe-time association or the rest() rule; this only changes what standing between us and deciding them. |
