11aa4ec7cf 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.

0db76bcc57 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.

be937e3d5d 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.

c4b5752713 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.

29d59cdb06 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.
