agent: tag the decoder states the port pins, and stop leaking credential config
Two fixes to push-work and the policy that goes with them.
**Tags.** The port's exporter depends on sylpheed-formats BY REVISION, so a
commit of ours is part of its build -- and the commit it pinned lived on one
auto/* branch and nowhere else. Deleting that branch orphans it; squash-merging
it is worse, because squash creates NEW commits, so main appears to contain the
work while the pinned sha becomes unreachable and the port stops building for a
fresh checkout. Silently, at their build, long after the breakage.
push-work now pushes with --follow-tags, which publishes annotated tags
reachable from the pushed commits, and MISSION.md says to tag whatever the port
needs. formats-pin-2026-08-29 at

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. |

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. |

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(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. |

re(ui): the game does query the display gamma -- measured, with its control
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. |

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: 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
600-780 s windows tried, or something regressed since

re: the English control removes the locale from the title-capture problem
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. |

re(ui): finish the top-level rotation census; record the JP-capture blocker
Two threads had converged on needing one capture this container cannot take, so this iteration records that and finishes something reachable. BLOCKED, written into MISSION.md rather than worked around: Q1's keyframe time association and the rest() rule for plateau-less elements both now hinge on a running capture of GP_TITLE build 7, the Japanese title. The console language is not settable here -- user_language appears only as DECLARE_int32 at four call sites with no DEFINE anywhere in the tree, and it is absent from the registered cvars in xenia-canary.config.toml. There is no flag to pass, and guessing one is specifically unsafe: run-canary's own header records that xenia calls ShowSimpleMessageBox from ParseLaunchArguments before logging starts, so a bad flag blocks forever with an empty log. Rebuilding canary to add the cvar would be improvising around the blocker; it needs a human decision. Neither question blocks the five menu screens. FINISHED: the disc-wide top-level rotation count, left running four iterations ago as a shell loop over `screen info --geometry` that never completed (it decodes every texture per build). Walking the placement region directly takes seconds. top-level elements with a keyframe group 15 493 carrying a non-zero rotation 2 152 (13.89 %) Both controls pass: GP_TITLE build 4 reports 0 (its rotations are the nested ptloop records) and GP_DIALOG build 0 reports the expected two. The control earned its place -- the first version indexed the pak with a `screen list` BUILD number and got 0 for a screen that has two, because GP_DIALOG build 0 is entry 2. GP_TITLE maps 1:1, which is how the assumption survived. METHOD line added. Two free corroborations of the rotation decode. The rotated population is dominated by tactical-map ship icons -- pbb_destroyer 444, pbr_destroyer 402, pbr_fighter 276 -- i.e. markers rotated to heading, the single largest use of the field on the disc. And GP_TITLE entry 7's Japanese wordmark pieces settle from ALTERNATING tilts: ptlogo3a r = 0, -14, -4, -1, 0, ... ptlogo3b r = 0, +14, +4, +1, 0, ... ptlogo3c r = 0, -14, -4, -1, 0, ... Same magnitudes, opposite signs, all decaying to upright. A misread field does not produce that. |

blit() and fill_quad() both opened with
let sx_pct = if kf.scale_x == 0 { 100 } else { kf.scale_x };
so an element whose pose is collapsed to nothing rendered at FULL SIZE.
I first described this as "a 1-pixel sliver", reading the .max(1) in the
size arithmetic two lines below -- the guard above it meant .max(1) never
saw a zero. Read the whole function, not the lines you went looking for.
Control run before the change: if 0 meant "unset", something on the disc
would use it throughout. Nothing does.
elements with a keyframe group 15 493
at least one keyframe at scale 0 2 166
EVERY keyframe at scale 0 0
zero is a transient the element grows out of 1 762
ptlogo_eff3.t32 runs 0% -> 200%. An "unset" marker no element ever uses
throughout is not a marker.
Both functions now return without drawing when either scale is 0.
Reach: 24 of 24 renders byte-identical across GP_TITLE (all 16 builds),
GP_PAUSE_MENU and GP_OPTIONS -- additive on every screen the port needs.
195 elements have a guessed rest pose at scale 0 and 126 of those have a
non-zero alpha, so the old code painted them; all 126 are in
GP_READY_ROOM.pak, which S1 already declared a no-go. They are
tactical-map sprites at sx=0/sy=100, mid-horizontal-wipe, that the
coercion drew full-width.
So: a real correctness fix with no visible effect on the menu port.

re(ui): size the rest() guess disc-wide, and refute my own proposed fix
Follows up the defect found last iteration: rest()'s dwell fallback is
guessing whenever it runs. Two things were open -- how big it is, and
whether "rest = the last keyframe" is the fix. Both are now answered, and
the second is answered no.
plateau_census.py walks the placement regions directly instead of going
through `screen info --geometry`, which decodes every texture and cannot
do a disc-wide pass in reasonable time. Its control reproduces GP_TITLE
build 7's three fallback elements and names ptlogo_eff3.t32 among them
before counting anything.
elements with a keyframe group 15 493
no plateau -> rest pose is guessed 3 807 (24.57 %)
... current rule returns invisible 1 711 (44.9 %)
... current rule returns scale=0 195 ( 5.1 %)
the two candidate rules agree 1 911 (50.2 %)
195 elements get a rest pose with scale 0%, which is not a pose. And
disc-wide the choice of rule is not cosmetic: the candidates agree half
the time.
But the port's exposure is one element. Across main menu, EXTRAS, title
and the developer splash, 14 elements are plateau-less and the two rules
agree on 13. The single disagreement is palogo_anima_eff.t32.
And "last keyframe" loses there, on a control that needed no new capture:
the splash carries three sibling glows with identical structure and
identical times --
palogo_gamearts_eff 15:a=0 30:a=255 45:a=255 -:a=0 plateau -> visible
palogo_seta_eff 15:a=0 30:a=255 45:a=255 -:a=0 plateau -> visible
palogo_anima_eff 15:a=0 30:a=255 45:a=212 -:a=0 no plateau
-- differing in one byte. "Last keyframe" makes anima alone invisible
while its two siblings stay lit. The capture agrees weakly: box-mean
ratios capture/render are gamearts 0.717, seta 0.723, anima 0.772, and a
glow we drew that the game does not would put anima below its siblings,
not above.
So the defect is measured and the fix is still undecided. Nothing in the
decoder changed.

re(ui): withdraw the render evidence -- rest()'s dwell fallback is unsound
Last iteration I reported a 13.1% render change in GP_TITLE build 7 as
evidence AGAINST the keyframe-time shift, arguing that language twins
should match in brightness. Withdrawn. Localising the diff to an element
shows it is not about the time association at all.
The element is ptlogo_eff3.t32, a transient bloom:
46: (98,42) 100%,100% a=0
61: (108,72) 0%,0% a=0
103: (108,72) 200%,200% a=255 r=80
-: (108,72) 0%,0% a=0 r=150
No two adjacent poses are equal, so there is no plateau, and rest() falls
through to its longest-dwell fallback. The longest gap is 61->103, during
which the sprite grows from nothing to 200% at full alpha and then
collapses. The rule returns whichever end of that movement the indexing
lands on: the invisible frame as decoded, the 200% peak shifted. An
896x389 sprite at 200% is larger than the screen, which accounts for the
entire 13.1% and the entire 4.9-unit luminance gap. I was comparing a
heuristic against itself.
The defect generalises, and structurally. A dwell gap is time spent
interpolating FROM pose k TO pose k+1; neither pose is held during it
unless the two are equal -- which is a plateau, and the plateau path has
already returned by then. So the fallback is guaranteed to be guessing
every time it is reached, under any reading of the times. Every element
with no two adjacent identical poses has a guessed rest pose, in our
renderer and in anything built from it.
Consequences: the case FOR the shift (26x on the hold:fade-out ratio) is
no longer opposed by render evidence -- 10 of 11 builds byte-identical,
the 11th differing only through this heuristic. It is still not adopted,
now because it flips this element to the visibly wrong answer, so the
shift and a decision about plateau-less elements must land together, and
neither half has a capture to verify against.
Default-mode suite green (122 passed, 0 failed across 3 suites so far).

re(ui): the keyframe-time shift is favoured 26x by timing, rejected by a render
Follow-up on last iteration's unadopted candidate (+36 holds the NEXT pose's time, not its own). Two new results, pointing opposite ways, and both are reported. FOR, and calibration-free: the observed full-alpha hold : fade-out ratio on palogo_gamearts is 83 : 13 frames = 6.38. The shifted reading predicts 8.00. The current reading predicts 0.25 -- off by 26x. With the glow's 2 units/frame fixed and nothing else free, the current reading says the logo holds full alpha for 2.0 frames; the capture holds it for 83. This is no longer the shape argument the candidate rested on. Also for: rest()'s plain max-dwell fallback picks a=0 -- a transparent pose, for a publisher logo -- under the current reading, and the visible a=255 hold under the shift. Only the rest_plateau special case rescues the render today, and that is the case the port agent reported a bug in. AGAINST: rendering every build of six UI paks under both readings, 10 of 11 compared are byte-identical and one changes -- GP_TITLE build 7, the Japanese twin of build 4, by 13.1% of pixels. Build 4, the one verified against a live capture, is unchanged either way, so the single build the shift moves is the one with no capture to adjudicate it. The proxy goes against the shift: language twins are the same artwork, and build 7 reads 70.94 mean luminance as decoded against build 4's 71.41, but 76.32 shifted. Correlation does not separate them (0.6206 vs 0.6201). These constrain different things -- timing versus pose selection -- and rest() is a heuristic layered on the times, so moving the times moves its tie-breaks. Adopting the shift means revisiting that heuristic in the same change, with no build-7 capture to verify against. Default UNCHANGED. Experiment reachable via SYLPHEED_KF_TIME_SHIFT=1. Shifted-mode suite: 122 passed, 0 failed across 3 suites at commit time. |

re(ui): Q1 -- the interpolation law holds, the group timeline does not
Q1's gate asks whether the ramp is linear. It is, and that result stands: it rests on the splash's _eff glows, which reproduce exactly. This adds the part that does not. The test is a calibration, not a fit. Fix the clock on palogo_gamearts_eff -- declared 15-unit fade-in 0@15 -> 255@30 against captured alphas 34,68,102,136,170,204,238, a constant step of 34, giving t = 2f - 171 -- then check that against the glow's own next landmark: its declared hold ends t=45, predicted frame 108.0, observed last full-alpha frame 107. Then apply it to palogo_gamearts in the same bundle and the same frames, with no free parameter left: declared a=232 at t=206 -> frame 188.5, observed alpha 255 declared a= 32 at t=210 -> frame 190.5, observed alpha 255 The logo is still at full alpha nine frames after it should read 32; its fade-out runs ~17 frames late; its declared 80-frame fade-in is never drawn. Not culling -- the same element is submitted down to a=7 on the way out. Calibration-free version: the declared fade-out spends 12 of 16 units dropping 23/255 of the alpha, and the capture has no such plateau. Candidate, offered and NOT adopted: if +36 held the NEXT keyframe's time, the fade-out shape fits (RMS 4.05 vs 12.13, two elements) and the decoder's "last block's time is unreadable" special case disappears -- the last block would simply have no successor. Rejected for now because it explains neither the missing fade-in nor the lateness, and because the _eff elements cannot discriminate between the readings at all (with four blocks the shift only relabels the phases). Decoder unchanged. Also withdrawn, mine, within the iteration: "the _eff glows hold a constant alpha 33". They ramp 34 -> 255 in steps of 34. I printed the series minimum and read it as its range, with a "14 distinct colours" column sitting next to it saying otherwise. |

re(ui): rotation is not nested-only, and the pivot-anchored scale is measured
Two corrections and one new confirmation, all from finishing the sweep I left running last iteration. Refuted, by my own sweep, within the hour: "rotation appears to live only in nested .rat leaf records". That held for GP_TITLE, GP_BUNK and GP_CHALLENGE -- the three archives the sweep had reached when I wrote it -- and fails on GP_DIALOG and GP_DEBRIEFING_PILOTLOG, which rotate top-level elements. Scoping the claim made it cheap to withdraw, but the sentence should have waited for the sweep. Those top-level cases are the best evidence on the disc, and they show up in `screen info --geometry` without a hex dump. GP_DIALOG build 0: pceff03/pceff04 ramp r = 90 -> 30 -> 10 -> 3 -> 0 while alpha ramps 0 -> 255 and they slide into place -- a swing-in settling upright. Build 6: pzeff02 ramps 43 -> 61 -> 75 -> 90 while scaling 112% -> 200% and fading to 0 -- a spin-out. Rows committed as reference data. New: the pivot-anchored scale term in blit, kf.x - pivot*(scale-100)/100, was implemented and reasoned about but never measured, because every element previously examined sits at 100% scale where the term is exactly zero. The ptloop pair scale 600% and 800%, where it is worth 450 and 630 px. Formula predicts centre y = 360.0 for both; capture measures 359.1 and 360.0. Top-left anchoring predicts 810 and 990. Horizontally it makes t-from-position agree with t-from-alpha to 0.33 / 0.65 units against ~8 without it. That agreement does NOT prove linear interpolation -- both fields were inverted through the same linear map, so a shared easing curve cancels. It shows position and alpha ride one shared parameter. Recorded as such. The disc-wide sweep is still running; the count is incomplete, the existence is settled. |

re(ui): decode keyframe +12 as screen-plane rotation in degrees
The rotated quads on the title screen come from the keyframe block after all. The earlier negative -- "every GP_TITLE build 4 element has all three angle words at zero" -- read the right bytes over too small a region: it walked the top-level declaration table, and the rotated elements are the nested leaf records ptloop01.rat / ptloop02.rat. Confirmed against the framebuffer rather than against our own renderer. The two records declare +12 = 30 and -45; the GPU capture submits their quads at +30.26 and -45.28 degrees -- magnitude and sign, two different values. Corroborated by shape in GP_BUNK 117ca14f, where +12 ramps 0 -> 360 with position, scale and alpha constant: a spin in place. Identifying which draw it was needed edge lengths, not bounding boxes: 400x1076 and 400x1444 against pteff03/pteff03a 399x180 at the elements' two different declared scales, 600% (1080) and 800% (1440). The same test names three known-positives in the capture (ptlogo1, ptcopyright, ptbtn00), so it passes its own control. Keyframe gains rotation_deg plus unknown_4/unknown_8, carried rather than dropped. NOT rendered -- ui_layout::blit is axis-aligned only, so the reference renderer and the port will both draw these upright until a rotating blit exists. The census tool ships with the trap that broke its first version: nested RATC blobs are not 4-byte aligned, so an aligned scan found 0/3 of its own control blocks and missed 16 341 blocks. Disc-wide +12 is non-zero in 14.50 % of 83 862 blocks. sylpheed-formats tests, SYLPHEED_DISC set: 131 passed, 0 failed across the 6 suites finished at commit time; the run had not yet completed. |

re: the skewed draw is not the swoosh -- refuting the identification five
iterations of work were built on I flagged last iteration that "draw 2 is the swoosh" was an inference I had never checked. Checking it took one line, and it is wrong. Converting the quads from NDC to screen space: quad A spans y -209 to 925, quad B spans y -292 to 1012. Both cover the full screen height and run well off it. The swoosh, ptlogo_back2, rests at (71,126) and is a 234-pixel band at y 126 to 360. Draw 2 is not it. A candidate offered as one: the two ptloop sweeps. pteff03a is 399x180 with element scale (100,800), so 399x1440, and pteff03 carries (100,600) -- two long thin sprites, two quads, and the drawn vertex alphas 0xC3 and 0xB6 sit inside the 0x80 to 0xff ramp those records declare. Not confirmed; no texture or position match was made. If that is right it matters, and I have written it conditionally rather than acting on it: our renderer parks those sweeps at their final keyframe, both off screen, and draws nothing, while the game draws them across the screen. That would mean the capture caught them mid-sweep inside their t=150 to 600 window, and that the "groups hold" reading needs re-examining for those two elements. What this cost is worth stating plainly. Five iterations -- the additive blend test, the pivot analysis, the vertex-colour capture -- were built on an identification made by elimination on one screen and never checked against the draw's own coordinates. The eliminations themselves stand, because each was measured against the capture rather than against the identification. The chain that pointed them at ptlogo_back2 did not. METHOD takes the general form. |

re: the swoosh is solved -- the game draws it as rotated quads and our
blit cannot Ran the route I corrected last iteration, and it answered the question I had classified as undecodable. First the ninth candidate died: every vertex colour in the whole capture is <alpha>FFFFFF, white RGB with only alpha varying. The game passes no colour, so that hypothesis is refuted from the running game rather than from the file. Then the geometry gave it away. Draw 2 submits TWO PARALLELOGRAMS, neither axis-aligned -- edges (0.54,-0.56) and (0.44,0.79), roughly 45 and 61 degrees, both extending to y=+/-1.81 in NDC, well off screen. That is the diagonal Z stroke. And ui_layout::blit walks rows and columns of an axis-aligned rectangle; it has no rotation at all. So we blit the sprite upright where the game draws it skewed, which is exactly the signature I measured: right on average at +1.83, right in position with the correlation peaking at zero shift, wrong in structure at 0.70. Nine candidates, and the answer was never going to be a field, because the difference is not in the sprite -- it is in how the quad is built. Two things left open and written as such. The decoded keyframe carries fade, scale, tint, x, y and time and NO rotation, so where the rotation comes from is not decoded. And the pink-versus-white reading I have been carrying was a visual comparison of two differently-shaped renderings; it should be re-checked after geometry rather than treated as a separate defect. |

re: full suite green, and correcting the route I recommended last
iteration Two loose ends, both on my own work. The disc-gated suite finally completed: all six binaries, 131 passed, 0 failed, one pre-existing ignored. So the rest() fix and the T8adImage flags field are fully verified rather than verified-on-three-binaries. The reason earlier attempts produced empty logs was that the tool timeout's SIGTERM reached the whole process group; setsid nohup survives it, which is now a METHOD line. And a correction that matters more. Last iteration I closed the swoosh as undecodable from the disc and named a per-draw GPU capture as the next route, "because it reads the actual blend state". It does not. Reading command_processor.cc, each captured draw records primitive type, index count, index-buffer address, VS and PS ucode hashes, the pixel shader's texture bindings, and vertex attribute 0 of binding 0. There is no RB_BLENDCONTROL dump. So the route splits, and I have said so rather than leaving the wrong version standing: the capture can test a per-draw VERTEX COLOUR today with no code change, which would explain white-versus-pink directly, and getting the blend mode itself needs a Canary change to dump the blend registers. Either way it is instrumentation rather than another field. The general lesson goes in METHOD too: validate a recommendation before leaving it as advice. A named next step is a claim like any other, and I made it without checking. |

re: the capture is settled after all, and the swoosh is undecodable from
the disc Testing my own caveat instead of leaving it hanging. I had worried the plate-free title capture at t=4.0s was too early, since elements carry keyframes out to t=600 and I had judged "settled" from mean luminance, which cannot see a thin sprite still moving. The plate sits at y 550-600 and the swoosh band at y 112-225, disjoint, so a LATE capture works even with the plate present. The band correlates 0.7342 at t=4.0s and 0.7353 at t=21.5s -- identical to a thousandth over 17.5 seconds, with the band mean flat at 127. So the band is settled by 4 seconds, the capture I handed the port agent is sound, and my caveat is withdrawn. It also corroborates the earlier finding that groups hold: nothing crosses that band in 22 seconds. That was the seventh candidate for the swoosh and the last one that was not a format field. Pivot is inert at scale 100 and there is no displacement anyway; fade is white-with-alpha; tint is white; the texture is blue-leaning; additive via +0x04 bit 0x02 makes everything worse; the capture is settled. The residual is stable and modest -- band mean +1.83, edge-correlation 0.70 against 0.92 frame-wide. So I have classified it rather than generating an eighth candidate: undecodable from the disc, with the reach written out. And I have named where a next attempt should start, which is not another field -- a per-draw GPU capture of the running guest reads the actual blend state, vertex colours and draw order for that band instead of inferring them from the file. That is where static RE stops here. |
