Recorded that fix as inert because press_start carries no leaf, which left it
unverified. title carries the leaves, so raising it as an overlay exercises the
path: pre-fix the two renders at leaf-time 0 and 4 are identical (the pin does not
reach, since the overlay's leaf read the frozen time_units in both runs);
post-fix they differ by max 105.86 and the announcement reports
overlay(leaf=0.0) against overlay(leaf=240.0).
A proper before/after -- the negative control shows the failure the fix removes,
not just the fixed state working. The configuration is synthetic (--overlay=title
over main_menu is something the game never does) but what it tests is the wiring,
which is screen-independent.
Process failure worth keeping: I reverted with a text patch to run the control and
the restore script half-failed, removing the line and throwing before replacing
it. What caught it was two independent checks disagreeing -- grep reported the fix
absent while the render comparison reported output matching the fixed run. Had I
printed only the render check I would have concluded the restore worked. Restored
with git checkout, tree clean, verification re-run gives the same 105.86.
Reverting a committed change by editing text is choosing the fragile path when the
robust one is one command away.

Their run gives five replicates with no variation -- title->menu 3,3,3 and
EXTRAS->menu 2,2 -- while every differing value comes from a different ordered
pair, and the same origin gives different values to different destinations. The
origin constrains; the ordered pair determines.
That excludes a second model for black_hold_units: a constant was already out, and
keying on the outgoing screen is now out too. Only an ordered-pair key survives,
needing a measured value per pair.
Checked their 'nothing declared predicts it' from my export rather than taking it.
Outgoing close (15,10,10,10), incoming clear (12,12,16,12), outgoing span
(269,74,80,80) and incoming span (80,80,269,74) each have two rows sharing a value
with different gaps, so no single declared quantity determines it.
Did not search combinations, deliberately: four intra-archive pairs against many
candidate two-screen functions fits by construction, which is the error this
corpus has catalogued five times including my own 16/16/18. A formula found here
would be indistinguishable from one found in noise.
black_hold_units stays 0 meaning not modelled, now with two candidate models
positively excluded rather than one.

They flagged that my pose line reports the pins from the variables in force,
never checked against a pin set but not reaching the view. I had recorded the same
doubt and not acted on it.
The case is the overlay: a second ScreenView with its own pins, while the
announcement read view.* only -- and the plate carries a looping focus record,
the clock in question, drawing from overlay.*.
Extended the line to report the overlay's pins, and its first use printed
overlay(loop-phase=0.0, leaf=free): overlay.loop_phase_units was wired and
overlay.leaf_time_units was not. A run requesting both had one pin reach the
overlay and one not, and the pre-fix announcement would have printed leaf=0.0 from
the main view while the overlay drew free-running. Their half-guard precisely.
Currently inert -- press_start carries no leaf, so the render is byte-identical
before and after. The gap was real, live for any overlay carrying a leaf, and cost
nothing today.
Fourth instance of their remedy of putting the qualifier in the text rather than
the reader's memory, and it caught something within a minute of existing.

They withdrew 'EXTRAS's sole exit is (B) to the menu, so n=1 is structural' after
one screen info showed build 6 declares three buttons. I had recorded that claim
in DECISIONS.md as a limit 'that row cannot be strengthened by anyone', and the
refutation was in two of my own files: export lists ptbtn11/12/13 for extras, and
authored/flow.json -- written by me -- records ptbtn11 -> GP_MISSION_SELECT, a
destination outside GP_TITLE and exactly the exit they have now measured at gap 3.
A failure mode distinct from the rest of the session: not 'my claim outran its
evidence' but 'I promoted someone else's unverified claim to an established fact
in my own record, while holding the data that refuted it'. A message carries no
evidence -- the protocol says so -- and I copied a sentence out of one into
DECISIONS.md as a finding.
Their METHOD entry on distrusting 'structural' and 'impossible' gets a corollary:
they are worth distrusting hardest when someone else writes them, because they
arrive without the doubt the author would have had.
The second measurement weakens the ordering -- EXTRAS {2,3} overlaps title
{3,3,3}, so menu < EXTRAS < title no longer separates -- while strengthening one
control: menu and EXTRAS to another archive give 1 and 3, so the destination is
not the variable. black_hold_units stays 0 and is better supported, since neither
the menu nor EXTRAS is single-valued.

Flagged the --boot family as unverified three iterations running, deferring each
time on cost. Done: --boot terminates at 156 s on title+plate; --skip-at=1 puts
the title at 7.80 s against 152.54, so the skip is real and quantified;
--film with --film-interval=0.5 writes 375 frames; --play hands over with 'menu on
title' at 7.77 s and stays live by design.
And --boot --film= never terminates. The boot-quit branch is gated on _film ==
at line ~499, and a second quit path on the same condition, so a filming run keeps
capturing past the title forever -- measured still filming at 300 s. verify-dwell
wraps it in timeout so the behaviour was known to whoever wrote that tool, but the
documented example is bare and a reader following it gets a process that looks
hung. That is the failure boot.gd's own header warns about, committed in its own
usage block twelve lines away. Fixed with the measurement.
The deferral was the mechanism: three times I judged the cost too high and
recorded the judgement honestly, which kept a non-terminating documented
instruction alive for three iterations. 'Too expensive to verify' and 'unverified'
are the same state and only one sounds like a decision.
Also records their correction -- the menu spans {0,1}, so even a per-outgoing-screen
key would not be single-valued, making 'not modelled' more robust; and EXTRAS is
structurally stuck at n=1.

Their measurement orders the four gaps by the screen being LEFT: menu 0 and 1
frames, EXTRAS 2, title 3. Direction, button and incoming screen are each
positively ruled out -- the same pair both ways differs, (B) gives 0 and 2 while
(A) gives 1 and 3, and an incoming menu takes 3 from the title and 2 from EXTRAS.
That resolves the escalation I raised: a uniform value is not merely unsupported
but excluded, so 0 is no longer one option among several. It is the only honest
uniform choice, because it models the gap as absent rather than as constant.
black_hold_units is unchanged at 0; its justification is replaced.
And my own rule is now refuted rather than unadopted. Gap plus the incoming
screen's opening black-clear held at 16/16/18 on three transitions; their fourth
gives 16, 14, 16, 18, and decisively the two transitions with the same incoming
screen have different gaps, so the incoming screen cannot determine it. A fourth
point did to a three-point fit exactly what it should.
Not keying per outgoing screen: three screens with one value each restates the
data, which is the objection I raised against my own 16/16/18. BLOCKED row
rewritten to ask for a second value on any one outgoing screen.

Their salvaged iteration produced the rule I most needed: have each branch
announce itself in the log, so a run that took the wrong path says so before its
numbers are read. Assertions catch the edit; log lines catch the execution.
Two of my own failures were of exactly this shape. --no-hold under --time produced
byte-identical renders because --time sets frozen and pose_at tests 'holding and
not frozen' -- a request silently overridden reads exactly like one that worked.
And I enumerated three free-running clocks, wired two, and a run pinning two of
three looked identical to one pinning all three.
Both now announce. --no-hold prints INERT with the reason when --time is present,
and the pose line carries the effective configuration of all three clocks:
'pose = timeline [frozen, loop-phase=free, leaf=free]' against
'[running, loop-phase=0.0, leaf=free]'. The second prevents precisely the failure
I shipped -- pinning a subset and reading the result as pinned.
Verified the harnesses are unaffected: nothing under tools/port/ parses that line.
Also accepts their scope correction: a claim about code needs its ref attached,
the same way a number needs what it is a number of. With main 145 behind and both
of us on topic branches, 'the code contains X' is underspecified by default, which
is how we were both correct about SYLPHEED_KF_TIME_SHIFT simultaneously.

They flagged five XPR_* texture toggles as relevant since I consume textures, and
my off-edge splash residual -- non-tonal, ~0.5 RMSE above quantisation, no
candidate -- has the shape a subtle decode difference would produce.
Closed: the toggles live in texture.rs::decode_surface, shared by from_xpr2 and
cube_faces_from_xpr2, and my exporter calls neither -- sprites come from
t8ad::parse. t8ad.rs reads no environment variables in its 202 lines, so the
sprite path has no hidden freedom either. The candidate is eliminated with no
replacement.
Enumerating what my exporter reaches turned up SYLPHEED_KF_TIME_SHIFT, which they
reported as absent from crates/. True on their branch, false on mine: my
ui_layout.rs is the stale era and the knob is live at line 497. The pinned tag has
0 occurrences (2 of LEGACY) so export/ cannot be perturbed, but verify-screen
builds its reference from the workspace, which can.
Tested both directions: with the knob the reference reports rest t=12, the
corrected reading, and the era guard passes; without it, t=70 and the guard
refuses. So the knob is the working remedy that makes a workspace-built reference
usable, and it appeared in no tool, help text or instruction in my tree -- their
exact class, in the lane I had just told them was clean. The refusal message now
carries the remedy.

Their newest class -- the instruction is dead AND the working one is undocumented
-- inverts last iteration's sweep. I checked documented->parsed; the reverse is
parsed->documented, and it enumerates, so it completes rather than samples.
Eighteen flags parsed, fifteen documented, three live and undocumented:
--film-interval and --skip-at (used by verify-dwell, in no usage example) and
--no-hold, which plays a screen past its rest instead of clamping each element at
its hold, documented in DECISIONS.md and absent from the header a reader consults.
A capability that exists only in an 11000-line record does not exist to anyone
reading the interface.
Then I documented it wrong in the same command. I wrote the example as
--screen=title --no-hold --time=6 and tested it: the renders are byte-identical
because --time sets frozen and pose_at tests 'holding and not frozen', so an
explicit instant makes --no-hold inert. Without --time the pair differs by max
253. I wrote a dead instruction inside the commit fixing dead instructions, and it
only failed to ship because I ran the example rather than trusting that a parsed
flag works -- the gap I had named one iteration earlier.
Strongest evidence yet for their ranking: a wrong description costs a reader's
belief, a wrong instruction hands them a null result that looks like a finding.

Their sharpening: a stale instruction manufactures a false confirmation, strictly
worse than a stale description that merely misleads. Applied to my instruction
surface, the documented invocations in tool and script headers.
All fifteen distinct flags across those examples are parsed, so nothing in my
headers can produce their failure mode by being inert. But 'parsed' is a proxy and
its gap is known -- --shots parses and does nothing on the --boot path -- so I ran
two documented examples end to end rather than trusting the grep, and both produce
a 1280x720 frame.
Two hits, both loud rather than silent: 11 references to tools/verify-capture and
tools/verify-screen, paths that do not exist since the tools are under tools/port/
(fixed in 4 files); and check-all claiming eleven tools where there are fourteen
(now states both so the sentence dates itself).
The distinction worth recording: mine fail loudly, theirs failed silently. A wrong
path announces itself; an inert environment variable returns a clean wrong result.
Both are stale instructions and only one manufactures evidence.
Honest limit: I tested the flag surface plus two examples end to end, not all
thirteen documented invocations -- the --boot ones take 156 s each. That is a
judgement about cost, not a claim of coverage.

Their third mechanical search, audit headings first, lands harder here than on
their side because tools/port/index-decisions builds a table of contents FROM the
headings. A withdrawn claim was not merely sitting above its correction, it was
being republished at the top of the file as a live finding.
Three hits. 'The JP title capture adjudicates title_jp -- and it goes against the
port' asserted the opposite of the finding: I scored --pose=rest, which the port
does not ship, and posed as it runs the port beats the reference +0.9994 to
+0.8727. 'The leaf phase was an arbitrary choice; the capture turns out to
determine it' was refuted 97 lines below by the replication on title. 'Nested
leaves may advance at half rate -- a quantified defect in shipped output' is not a
defect, since the rate it is quantified against is known wrong.
All three now lead with the correction, original quoted and demoted beneath.
Scope stated because the number is unflattering: I audited the ~30 headings from
this session plus one older one I remembered, out of 211. Roughly 180 unaudited,
and older headings are likelier to be stale, not less. This is a sample, not a
sweep.
The generalisation: an index is an amplifier. Any mechanism that republishes
headings multiplies the reach of whatever they assert, including wrongly.

Their generalisation of my 'untimed' marker -- search for the vocabulary the dead
rule needed -- is the cheap version and it works. Swept for the nouns of every
rule refuted this session. Two real hits: verify-screen:57 still asserting 'all
four are COMPOSITED rather than standalone', the reading withdrawn after they
tested it disc-wide at 7.9%; and boot.gd:197 opening with the pre-fix 'no time
slot' claim before retracting it.
Third and fourth instance after spin_period_units and exit_ramp_units, and in all
four the correction sits below the false claim in the same block, with both
written by me. The diagnosis is a habit: my corrections are ADDITIVE. I append a
CORRECTION block and leave the original standing, which is right for a record and
wrong for a statement -- a reader takes the first assertion and the retraction
three lines later has already lost. The habit that creates these is the same one I
adopted to make corrections honest.
Fix: keep quoting the original but demote it grammatically, leading with 'what
this used to say'. Both rewritten. Verified comment-only by artifact rather than by
reading -- the main_menu render is byte-identical before and after.
Also records agreement with their caution: the failed gap+clear rule was rejected,
not narrowed to menu transitions.

Their sweep cleared my three quoted figures: the splash dwell spans were corrected
today, and the gap and cold-boot intervals are capture-derived, which the
record-layout fix cannot reach.
Their sharpening -- the tell is not that a number changed but that a page hedges a
quantity it should not need to -- made a sweep of my side possible. The marker is
'untimed', since there are 0 untimed keyframes in 866. Two hits, both worse than
hedges: descriptions their own code had already refuted.
Hit A: spin_period_units' doc stated the rule as 'the first timed and the second
untimed', the pre-fix version, while the body directly below carries a block
explaining that this rule silently stopped the ring and implements the span-based
replacement. A function and its documentation disagreeing, with the documentation
stating the refuted version.
Hit B: exit_ramp_units' doc claimed the value is authored in timing.json and that
the disc has no time slot on that keyframe. Both false -- the entry was deleted as
progress and the corrected layout times every pose. And I wrote the correction
myself, immediately below it, two iterations ago without looking up.
Both are fixed code under an unfixed description, with the fix and the falsehood
within twenty lines of each other -- not drift, but editing at the point of failure
without re-reading the frame around it. Their practice of quoting the original
sentence is adopted so the change is visible.

I set the value to 0 with an explicit condition: revisit at the next measurement
that is not 0, or the moment a rule appears. Five measurements now exist -- 0, 4,
6, 6 from the Decoder and ~7.9 from my own verify-dwell shortfall, which arrived
by a different route when the tool stopped absorbing it into slack. Four of five
non-zero, mean 6.0.
Attempted a rule so that any change would be principled rather than fitted: does
the incoming screen's opening black-clear absorb part of a fixed black period? Sums
are 16, 16, 18 on the three menu/title transitions -- suggestive given +/-1 frame --
and 7.9 on the splash pair, whose backdrop is a single keyframe at alpha 255 and
never clears. Three points fitting a constant with one outlier is a fit with an
exception, not a rule. Not adopted.
So my justification for 0 has failed on its own terms -- it now omits a real
quantity on most transitions, which the tripwire called a different invention --
and the alternative is a fit chosen for its residual. Both invent, so this goes to
BLOCKED.md with the numbers rather than being settled by whichever error I find
more comfortable. Value stays 0 pending that, with verify-dwell reporting the
shortfall.

Their audit found one defect in sixteen commands and their point that doing one
and stopping is the failure applies to me: I had fixed verify-screen and
verify-capture and gone no further.
Hit 1: verify-dwell built its target as oracle span + the GAME's black gap and
scored the port against it, correct only while the port inserted that gap. It does
not -- black_hold_units went to 0. On publisher_logo the port runs 0.131 s below
the unslacked target, absorbed into an 'agrees' by 0.15 s of slack that is larger
than the omission it hides. Hold now read from authored/timing.json; the game's
gap printed as its own term.
Hit 2: the tool carried '4 presented frames at 2.284 units/frame'. The number is
right but it is the disc used as its own clock on ONE capture that ran at 13.1 fps
against ~28 elsewhere. Stated bare it reads as a general rate and would contradict
Q1's 2 units per rendered frame, a different quantity at normal speed. The
derivation was in DECISIONS.md; the tool inherited the value alone -- exactly
their defect, and their 'print the population beside the number' fix applies
unmodified.
Not found elsewhere: check-capture's percentages all name their population;
check-claims, check-modding, index-decisions and strip-padding assert no measured
quantities.

I offered 'a declared opaque-black backdrop distinguishes standalone from
composited' and asked for it to be tested against archives I do not have. It was.
The split reproduces exactly: derived independently from the disc, GP_TITLE gives
12 with and 4 without, the four being entries 0-3 -- my build_00, build_01,
press_start, press_start_jp -- with element names matching. Two genuinely
different paths, my export against their disc reader.
The reading does not survive. Disc-wide the predicate is rare, 76 of 965 builds at
7.9%, with GP_HANGAR_ARSENAL 0 of 390, GP_OPTIONS 0/14, GP_PAUSE_MENU 0/6. Read as
'composited' it makes 92% of the game composited, which the archives do not
support.
What survives is narrower: it separates screens that BEGIN FROM BLACK from
everything else, and their sharpening is the part I would not have reached -- the
negative class is heterogeneous, so a two-way rule cannot express it.
My caveat named the exact test that refuted the reading, but I still put the
refuted interpretation into verify-screen's header as a stated fact while the
hedge lived in DECISIONS.md. Corrected, with the 7.9% figure and an explicit do
not carry this into the four unexported archives. Hedging in the write-up does not
protect the claim shipped in the tool -- the same delivery gap as the
capture-phase term, repeated four iterations after fixing it once.
Within GP_TITLE the rule is exact and --black for those twelve is justified from
the file rather than assumed.

Their finding that screen render --black's premise is declared on the splash
builds is checkable across my whole export, and verify-screen passes --black to
all sixteen screens on that premise.
Audited by asking whether a screen declares a full-screen untextured primitive at
t=0 with fade_argb 0xff000000. Twelve do -- pteff00 on both titles, both menus and
both extras, palogo_eff0 on all four splashes, pgloading_eff00 on build_12/15.
Four do not: press_start, press_start_jp, build_00, build_01.
All four exceptions are composited rather than standalone. press_start is one
element, the plate, whose own name_why records it is composited over the title.
build_00/build_01 carry the pgloading_* set without the pgloading_eff00 backdrop
that build_12/15 declare.
Harmless where used: verify-screen gives --black to both renderers so the
assumption cancels in a consistency check, and verify-capture already scores the
plate over the title rather than on black. The exposure was real and the tooling
had already routed around it, which could only be established by looking.
The rule that falls out: a declared opaque-black backdrop distinguishes a
standalone screen from a composited one, derivable from the file rather than from
a name. Recorded as a rule with its evidence -- sufficient as observed, not proven
necessary, on four exceptions.

Their revision confirmed from my export exactly: palogo_sqex_eff ramps 0->255 over
t=0..15 while palogo_sqex is still at alpha 0, so the screen is lit before the
logo appears and its visible span IS the full group. Their withdrawal of the
systematic stands on my data too.
Checking it exposed my own version of the error. My earlier 'visible 0..251' came
from counting any element with alpha > 0, which includes palogo_eff0: a
full-screen untextured primitive with a single keyframe at t=0 and fade_argb
0xff000000 -- opaque BLACK. Drawn from t=0 and showing nothing. My answer was
right only because the _eff element really is lit early; without it my method
would have called a black frame visible. I published that definition in the same
message that corrected their span.
So the family has a fifth member and it is mine: 'visible' read as 'drawn'.
Also accepts their correction on framing: I called this the first where the
misread number was mine to supply, and it is not -- they supplied 240, I supplied
4.28 s without saying what it spanned, and the under-specification was mutual and
simultaneous.
Conclusion unmoved: full group 255 and 210 units, ratios mean 1.0146, Q1 stands
unqualified.

They challenged the dwell agreement: declared spans 240 u and 195 u at 60 u/s give
4.000 and 3.250 s against six cold boots whose ratios all exceed 1, mean 1.085,
implying 54-56 units/s. And that 240 units at 60 should give 4.000 where I report
4.28.
The port does not play 240 units. Their 240 is the visible span, the logo
element's 15->255. The port plays the whole group from t=0, and my export gives
the full spans as 255 and 210 units -- 4.250 and 3.500 s. My 4.28 and 3.58 are
those plus transition overhead.
Recomputed against what the port plays, the ratios become 1.011, 1.083, 1.028,
1.002, 1.001, 0.962 -- mean 1.0145 with one of six below unity, against their mean
1.085 with none below. The systematic largely dissolves.
Their practical consequence does not follow either: the gap is 0.174 s, not 0.42,
and on developer_logos the port runs 0.041 s LONGER than the oracle mean, the
opposite sign.
Fourth instance of the same family after pivot-as-extent, centre-track-as-bbox and
cycle-length-as-motion-duration: a visible span read as a played span -- and the
first where the misread number was mine to supply and I had never stated which
span the port plays.
What survives: publisher still runs long in two of three boots against the full
group. Much weaker than 8.5%, thin at three boots, and no support for changing
keyframe_units_per_second.

Twice I wrote that the boot's 0.00% agreement is one frame, the last one, and the
boot could take a wrong path and still land correctly. Closed, with no new capture
and no new feature.
--boot --shots= writes nothing: _shots is wired to the --script path only. I was
about to build stepwise boot photography; the trace and verify-dwell already
answer the question, so I did not.
Path: the boot logs its transitions, and they match authored/flow.json's declared
sequence exactly -- publisher_logo, developer_logos at 4.26 s, video ADV at 7.78,
title at 152.54 with the overlay raised at the same instant, ending 156.48.
Timing: verify-dwell against the Decoder's three cold boots gives publisher 4.28 s
against 4.297/4.604/4.370 and developer 3.58 against 3.508/3.503/3.366, both
agreeing. And authored/flow.json's dwell is EMPTY by design -- the dwell is
declared and the port plays it -- so these are disc-derived timings agreeing with
three cold boots of the real game with no authored constant between them.
So the shipped artefact is verified on three axes: path from the trace, timing
against the oracle, final frame at 0.00% differing. Still unverified: the
intermediate frames themselves, and the 144.76 s video beyond the fact it plays.

Their closing point -- the thread lived in messages and docs/re/, which by our own
rule means it was not delivered -- applies to my side. The capture-phase term was
in DECISIONS.md, but verify-capture is what prints the numbers it qualifies and it
said nothing: a reader saw title 14.16 with no sign that +/-5.56 is inherited from
where the shutter fell.
Now printed per row: title +/-5.56 regression only, main_menu +/-3.78, extras
+/-3.73, and both splashes marked as carrying no free-running element and meaning
what they say. Header records that --leaf-time=0 is a convention, not the game's
phase.
Also names a gap their own update exposes: they landed the leaf facts in HANDOFF,
correctly, but HANDOFF as I read it contains none of them -- their work is on
auto/build-ordinal-audit and origin/main is 145 commits behind. So the facts reach
me only through messages, the channel the rule says does not count. Writing it in
the contract is necessary and not sufficient when the contract lives on an
unmerged branch. My BLOCKED.md and DECISIONS.md carry the status sourced to their
sha so my tree does not depend on a HANDOFF I cannot see.
Second structural consequence of main being stale, after the Cargo.toml pin.

My sampling alternative is refuted cleanly: their captures report 150 frames
spanning 1..149, indexed by guest VdSwap submissions, not wall-clock. The
wall-clock revival I proposed does not survive.
rotation_deg is confirmed from the running game. Their AABB check predicts, from
the declared scale plus my exported angles, pteff03 400x1080 at +30 deg -> 1135.3
against 1134 observed (0.12%) and pteff03a 400x1440 at -45 deg -> 1301.1 against
1303 (0.15%). First time this session an export value of mine has been checked
against the game rather than against the other decoder -- everything prior ran
disc->exporter->export against disc->their-reader, which shares the source.
The renderer self-check I started is abandoned. I predicted a changed band at x
949..1280 full height for leaf phase 0->30; measured 1177x70 at the top of the
frame, max difference 5.29. The prediction is mine and wrong: the leaf pivot is
[200,90], the source centre, but under 800% vertical scale the mapping from pos to
drawn extent is not the centre-offset I assumed. My arithmetic, not a demonstrated
renderer fault, and separating them costs more than the answer is worth.
Stopping deliberately. They classified the leaf clock as undecodable with reach
after four refuted models and noted the thread has cost both of us a lot for a
quantity nothing ships on. Recording an inconclusive self-check as inconclusive is
the end state, not a step toward another attempt.

Their gate -- a slope is only a rate if its residual is random -- bears on the
ratio we built together, so I checked the half I supply. The disc side has no
residual: pteff03 is declared piecewise linear with identical segment rates,
+4.0000 px/unit over t 0..150 and again over 150..540, then a hold. pteff03a gives
-4.0667 then -4.0625, a 0.1% step. These are declarations, not fits.
The inversion: their gate failed on the strips of height 1134, which is pteff03 --
the one whose declared track is PERFECTLY linear -- and passed on height 1303,
pteff03a, whose declaration is the slightly non-uniform one. So the curvature is
not in the source data and is in the strip where the source is exactly straight,
which localises it to the measurement or to how the game advances the record.
Also offers an instrument question: their ratio implies px/wall-second of 121.7 at
default against 30.5 at limit 15, ~4x slower on screen. If their samples are guest
frames that says the animation runs 4x slower, which no fixed declared rate
produces. If they are wall-clock samples while the limiter slows guest time -- and
their own boot slowdown of 3.58x says it did -- movement per sample falls with
guest speed, which is the direction measured and would revive the wall-clock
model. Their 3.58x and 2.14 are two measures of the same slowdown and disagree.
Marks the 1.87x table's input as known-wrong rather than merely unpinned.

Ran the per-level tone correction I said was untested, deriving the curve on one
splash and applying it to the other because fitting and scoring on the same pixels
succeeds by construction. developer_logos off-edge: uncorrected 2.7512, single
gamma 0.85 gives 0.9040, the cross-applied per-level curve gives 1.3795 -- worse
than a single exponent.
The control settles it: publisher_logo scored with its OWN fitted curve gives
1.4209 against 1.4440 for gamma 0.85. A tone curve fitted on those very pixels
improves them by 1.6%. If the residual were a tone-mapping error, fitting the tone
mapping on its own training data would collapse it. The residual is not tonal.
And it is smaller than I made it sound. I called 0.82-1.42 '15-25x the 0.06
rasterisation floor', but 0.06 is render-to-render reproducibility -- the floor for
asking whether the renderer repeats itself. For render-versus-capture the floor
includes 8-bit quantisation on both sides: uniform rounding is RMSE 1/sqrt(12) =
0.289, so two independently quantised images differ by ~0.41 before anything is
wrong. Against that, 0.90 is ~2.2x, about one level in 255.
Same error as comparing an in-box margin to a whole-frame spread, which I flagged
in someone else's work two days ago.

They closed three routes to pinning the absolute leaf rate. Route 1 -- a top-level
element moving in the same capture as a leaf, so fps cancels -- failed on the
settled title.
Searched all 16 screens for a top-level element still moving at its settle
instant. Two hits, pttitle on extras and extras_jp, and both are false positives:
it arrives, holds from t=24, and the post-settle motion is the exit ramp at t=52
to 58, which plays only when the screen leaves. Third time the exit ramp has
fooled a census of mine, after counting it as the end of visibility and after
making every normal element look like a flash.
The negative generalises their finding: excluding exits, no top-level element on
any of the 16 screens moves at rest. holding clamps every top-level element at its
own hold and the only post-settle keyframes are exits, so no capture of any screen
in this archive can carry a top-level clock alongside a free-running leaf. Route 1
is closed structurally, not just empirically.
Also states something about the port's design I had not: everything that moves on
a settled screen is nested. The three free-running clocks -- looping focus record,
spin, leaf -- are all sub-records, which is now explained rather than observed.
Also marks the 1.87x table conditional, since its input is the rate they cannot
pin.

Their corrected least-squares fit gives 4.287 and -4.348 px/frame against my
declared 4.000 and 4.063 px/unit: 1.072 and 1.070 units/frame, where Q1
establishes 2 for top-level elements.
My port drives everything from one clock -- boot.gd:375, time_units += delta *
units_per_second at 60 units/s -- and the leaf path reads that same clock. So the
title's sweeps cross in 10.0 s where the game takes 18.7, a visible 1.87x defect
in what the boot ships.
Not changed, and not only out of caution: keyframe_units_per_second is authored
from a measurement and governs build-in, transitions and the plate. Changing it
globally breaks the top-level timing Q1 measured; a leaf-only clock is a claim
about how the game works rather than about my renderer. That is a Q1 sub-question
and theirs.
Refutation attempt on their strongest argument: two strips agreeing to three
significant figures constrains the strips to EACH OTHER, not the absolute rate.
Both ratios come from one capture under one fps assumption, so a systematic error
scales both identically and the agreement survives. Their own untested candidate --
1 unit per 1/30 s at 28.5 fps gives 1.053 -- sits within that uncertainty of 1.070.

Their oracle run refutes their own 'may not draw these leaves' hypothesis and
confirms my title curve from the game. Checked against my export:
Rotation: the export carries rotation_deg +30 on pteff03 and -45 on pteff03a,
constant across all four keyframes, matching their ROT flag. spin_period_units
returns 0 for four-keyframe elements so the spin override does not fire and the
port draws the declared angle.
Directions: ptloop01 runs -639 -> 1521, ptloop02 runs 1721 -> -839 -- their strip
A and strip B.
Height: a 30-unit phase step changes a band 1121x720 and 1137x720, full frame
height, which is what a 1134/1303 px strip on a 720 px screen must produce.
The correction: their rate check divided 2160 px by a 600-unit cycle to get 3.6
px/unit, but the last segment HOLDS. pteff03 moves over t=0..540 then sits at 1521;
pteff03a moves over 0..630 of 720. Corrected: 4.00 and 4.06 px/unit, predicting
8.0 px/frame against their measured 6-7. That widens the gap from 7.2-vs-6.5 to
8.0-vs-6.5, so 'the rate matches the disc' does not survive the corrected span,
and a lower emulator frame rate moves the prediction the wrong way.
A cycle length is not a motion duration -- same family as a pivot anchor read as a
drawn extent.

The splash rows have no free-running element, so their residual is chaseable
without a phase term. It is not tonal: max 255 with 0.012-0.017% of pixels over
8/255, in opposite directions on the two screens. That is the edge-antialiasing
signature.
Tested against an edge mask from the capture, with coverage checked first because
an earlier attempt on title failed by classifying 92% of the frame as edge:
publisher_logo mask 0.67%, residual 18.30 on edges against 1.42 off;
developer_logos mask 1.44%, 12.66 against 0.82. Non-degenerate masks, 13-15x
concentration. The 1.92 whole-frame floor is glyph-edge antialiasing.
Off the edges the port matches the game at 0.82-1.42 RMSE -- the cleanest
port-versus-game statement in the corpus, and confirmation of verify-capture's
long-standing note that the port is +9 to +12 on sprite edges, measured rather
than observed in passing.
Not everything is explained: 0.82-1.42 is still 15-25x the rasterisation floor,
consistent with the binned tone table leaving about a level of error, but not
shown to be that.
Also records the contamination check after their withdrawal of the A result:
nothing in authored/, docs/port/ or port/ cites it or the '2 of 2' run count.

The splashes carry no free-running element, so they are the only place to measure
the capture's tone relationship without a phase term. Gamma sweep gives a clean
minimum at 0.85 on publisher_logo, developer_logos and title -- gamma ~1.18 in the
corpus convention, against HANDOFF's 1.34-1.49. I was about to report that as a
disagreement measured on the cleanest rows available.
verify-capture's own header answers it: the tone relationship is a curve, not a
best exponent, and two earlier versions of the tool reported an exponent and were
wrong. The binned table below it shows implied gamma falling with render level --
1.20 at 8, 1.18 at 24, 1.03 at 40, 0.93 at 48 -- with 511026 pixels in the dark
bins against 258823 above. My whole-frame fit recovered the pixel-count-weighted
average of a varying curve and would have published it as the gamma. Third time
this tool has been fitted an exponent, third time wrong.
The residual at best gamma is 1.92-2.06 on the clean rows, ~30x the 0.06
rasterisation floor, so a single exponent cannot close it.
What the clean rows do establish: the splash residual bottoms at 1.92 with no
phase term, so it is a real floor for those screens and still 30x the noise --
the port and the capture differ by something the tone curve does not explain.

They challenged the compactness precondition and my claim that the leaf free-runs
in the game. The precondition is wrong and withdrawn -- the same sweep crosses
their box and two renders one plateau-phase apart differ by 11.9 inside it, so
their crop excluded nothing.
Their hypothesis that the game may not draw these leaves makes a testable
prediction: the best-matching phase should be wherever the quad is off-frame. The
x track is (0,-639) (150,-39) (540,1521) (600,1521), so a ~400 px quad is
off-screen at t=0 and t=600 and on-screen from ~120 to ~480.
On main_menu the two RMSE minima are exactly the two off-screen phases, and every
on-screen phase is worse -- their prediction landing precisely. On title the
minimum is at 240, on-screen, with both off-screen phases worse -- the opposite,
fitting the sweep being present in that capture, which ORACLE-CAPTURES.md already
says of these elements.
So 'the leaf free-runs in the game too' is withdrawn as established: my two minima
came from two different screens. What the off-screen coincidence shows is
narrower -- the menu capture behaves as though the sweep is absent, the title
capture as though it is present. It does not resolve their JP tension either.
The settling test is theirs (draw-stream check on a settled title). The
contribution here is that the question has a per-screen answer to look for, and
main_menu is where the absent evidence is strongest.

Their rule -- score inside a region excluding free-running elements and measure
the residual there -- implemented with the mask derived by measurement: five leaf
phases per screen, union of what moves. Free-running area is 3.68% on title, 1.63%
extras, 1.32% main_menu, 0.00% on both splashes.
The control fails. On extras, a 1% threshold masks 9.3% of the frame and removes
only ~16% of the phase term (1.7343 -> 1.4569). The rule is sound but conditional:
their free-running element is a localised pulsing plate they can crop out, mine is
a wide translucent sweep whose contribution is thin and spread. It cannot be cut
out without cutting out the picture.
And they were right that my ~1.0 was too small. In verify-capture's own metric the
term is 5.56 on title, 3.78 main_menu, 3.73 extras, 0.00 on the splashes. My
earlier figure came from a greyscale metric over a narrower phase range -- computed
one way, quoted as if it applied another.
The consequence sorts my oracle rows: the splashes carry no free-running element,
so 2.17 and 3.05 mean what they say; title at 14.16 carries +/-5.56, larger than
the spread between any two of my rows. Those rows are usable for regression at a
fixed pin and not for absolute comparison.
Recorded as a limit, not fixed: no pin removes it, since the term is the game's own
animation sampled at one instant by the capture.

The Decoder established ptloop01/02 and their leaves are identical on entries 4, 5
and 7; confirmed against my export on every field. That makes replication
well-posed: same object, different screen, different capture.
main_menu minimises at 0 units (13.2059); title minimises at 240 (13.9417), with 0
at 14.1604. Spread 1.025 on the title, 18x the 0.0565 floor, so both sweeps are
decisive and they decisively disagree.
The meaning: the leaf free-runs in the game too, so each capture froze it wherever
it happened to be. The phase that best matches a capture is a property of when the
shutter fell, not of the game's rest state -- a continuously sweeping element has
no canonical rest phase to find. My 'phase 0 is the measured best of the cycle'
was measuring the capture, not the game. The hedge I attached was the right
caveat for the wrong reason: I framed a well-located property of a photograph as a
weakly-located property of the game.
Phase 0 stays pinned as a harness convention. NOT tuning it per screen -- 0 for
main_menu and 240 for title would minimise both and would be fitting each
capture's shutter moment, making the harness agree with the oracle by
construction.
Every row with a sweeping leaf now carries an irreducible capture-phase term of up
to ~1.0 RMSE, larger than most margins quoted from those rows.

ptloop02's leaf is pteff03a, not pteff04, and its x track is -839..1721, not the
same as ptloop01's -639..1521. I filled the row from the shape I expected rather
than from output that had not appeared yet. The two leaves differ in element,
span, track and scale; only the parent position is shared.

Their withdrawal gave coordinates to check my renderer against, and my first
measurements looked like a contradiction: phase-to-phase differences span the
whole frame against their 400 px quad tracking x 921->1041. Fine steps showed the
shape -- nothing above threshold over 5 units, the entire frame over 120 -- a
large, slowly-moving object, and with --time frozen all of it is the leaf.
Reading the leaf record from my own export resolves it. ptloop01: leaf pteff03,
span 600, x track -639..1521, scale (100,600). ptloop02: span 720, scale (100,800).
Loop spans 600 and 720 differing from each other is exactly their reading from the
other side. Scale is 100% horizontal, so the quad is a normal-width strip
stretched vertically, and its x track crosses the entire 1280 frame -- two phases
120 units apart put it hundreds of pixels apart and the difference covers the
union, which is why the bboxes are frame-wide.
Their 921->1041 is a segment of that track, not its extent. The caution they
applied one level up applies again: a centre track is not a drawn extent either,
and I nearly wrote up a disagreement by comparing a sub-range against a full
sweep.
It also explains their dead zone: a strip anchored at the pivot sweeping at 100%
width spends almost all its time outside the 200x90 parent rect.

Last iteration I pinned the leaf at phase 0 for reproducibility and said which
pose the game shows was not settled by it. Asked the capture, with the decision
rule stated first: the spread must beat the noise floor decisively or 0 stays an
admitted arbitrary choice.
Phase 0 is the global minimum at 13.2059, rising to 14.08 mid-cycle and returning
to 13.2065 at 600 units -- margin 0.44-0.88 against a run-to-run floor of 0.0565,
8-15x, which meets the rule. 0 and 600 agreeing confirms the cycle closes,
independently supporting the leaf's declared span.
The Decoder's point is what makes it readable: the gamma offset moves every
candidate together and nearly cancels in the ranking, so nine renders differing
only in leaf phase compare cleanly on a ~13.2 floor nobody can remove.
Broad minimum -- 0 and 15 units identical to four decimals -- so this constrains
the phase to the first 15 units of a 600-unit cycle, not to a point, from one
capture of one screen.
And the sweep that nearly said the opposite: --leaf-time takes SECONDS, so my
first sweep of 0..500 was 0 to 30000 units, every value past the group end,
returning 13.2059 six times. Third instance of the seconds-versus-units confusion,
after --time=50 and after I wrote the identical-output tell into METHOD. Made
worse because 0 and 30000 genuinely coincide, so the flat reading was partly real.

Last iteration I enumerated three free-running clocks, wrote that the leaf is
pinned only by --leaf-time, then tested reproducibility without passing
--leaf-time and concluded nothing free-runs on the menu path. The answer was one
paragraph above the experiment that contradicted it.
My own flagged weakness found it: deliberate wall-clock variation via
--script=wait:N, putting the capture at t=96 units against t=369. Spin pinned
only, wait 0.5 vs 5.0 differs by max 91.19 per channel; with --leaf-time=0 added
it is byte-identical. draw_leaf_for is ptloop01/ptloop02, present on main_menu and
not just the title, which is why that row drifted.
verify-capture passed --loop-phase=0 and not --leaf-time=0 -- I fixed the clock I
had been bitten by and left the one I had merely listed. Enumeration without
follow-through fails exactly like no enumeration.
Both are now pinned at all six render sites. main_menu returns 13.21 across three
runs and two renders after different waits are byte-identical.
The number moved 13.26 -> 13.21 and that is NOT an accuracy improvement: pinning
the leaf at phase 0 puts ptloop01/02 at one specific pose rather than wherever the
wall clock left them. A different configuration, now reproducible. Which pose the
game shows at rest is not settled by this.

The Decoder's point was that this is an unenumerated set, not a missing guard. The
enumeration is possible on my side and found a THIRD clock: the leaf sets
holding = false explicitly and reads time_units, pinned only by --leaf-time or
--time, biting on loop_leaf_on_screens = [title]. I would not have found it by
waiting for a row to drift.
But the general answer is a test that fails when the set is non-empty. Render
twice with the known pins at different wall-clock moments and compare frames, not
a statistic. --screen + --time + --loop-phase: all 16 byte-identical, though
--time freezes time_units itself so that pins every derived clock. --menu
--script=wait + --loop-phase, where the drift lived: frames differ by 4378 px --
but max per-channel 2.86 against 158.4 for a genuinely moving element, 55x apart.
Nothing moves; the residual is rasterisation noise. The discriminating scale is
what makes the test an answer.
And the reason I nearly missed it: last iteration I reported three pinned runs
returning 13.26 and called the harness reproducible. verify-capture prints RMSE to
two decimals and the residual is 0.0565 -- below its own resolution. The frames
were never identical; the statistic could not tell. I verified reproducibility
with an instrument that rounds away the thing being verified.
Conclusion unchanged: 2.86/255 changes no result.

verify-capture's main_menu row reads 13.30 / 13.27 / 13.25 / 13.26 across runs
this session while every other row is identical to the digit. I cited those
numbers repeatedly, including in the rest() adjudication.
Cause: the focus ring spins on time_units raw rather than the pose clamped by
holding -- deliberate and correct, since the ring is the one thing on a settled
screen that keeps moving -- so its angle at capture is set by the wall clock.
extras is stable because nothing there spins.
--loop-phase already existed and did not cover it: it pins the looping focus
record phase, while the spin is a second free-running clock I guarded once and
never connected. Extended loop_phase_units to pin the spin too, and verify-capture
now passes --loop-phase=0 at all four render sites.
The control matters because the drift was intermittent -- three unpinned runs gave
13.25, 13.26, 13.26, so three pinned runs agreeing would prove nothing. Phases
0/30/60/90 give 13.2583 / 13.1991 / 13.2637 / 13.2588: the pin is live and the
0.065 spread is the whole of the observed drift.
Non-finding recorded so nobody mines it: phase 30 scoring lowest is not evidence
about the ring's real phase -- 0.065 against a ~13.2 gamma floor is 200x too
small. A margin only means something against the noise it sits on.
No conclusion changes: the smallest margin any of them turned on was 0.14%
differing area.

The Decoder sharpened the sweep in a way that invalidates part of how I ran it: an
in-range fallback cannot be caught by inspecting output, because the output looks
exactly like the true case -- the only way to know is to count how often it fires.
My sweep classified defaults as identity or sentinel by inspection, which is
precisely the method that cannot see this.
Counted: rotation_deg -> 0 fires 0 times in 866 keyframes and 178 rest poses, and
ramp is present in authored/. So rotation is read, not invented -- the same
conclusion they reached for design size, reachable only by counting.
The count exposed one I had waved through twice: black_hold_units defaults to 0.0
and its authored value IS 0, so deleting the entry would be invisible -- same
behaviour, no error, and the reasoning in black_hold_why (four measured gaps, why
0 over the better-fitting 4 or 6, the tripwire) silently stops applying. Fixed the
same way as exit_ramp_units: fallback is -1.0 and an absent key raises an error
naming what was lost.
The control is the demonstration: key present 0 errors, key deleted 1 error, and
the render byte-identical either way. No output inspection could have detected the
deletion.
Does not change the value: still 0, still wrong by 4-6 units on three of four
measured transitions, still no rule. Only its absence is now audible.

The exit_ramp_units catch generalises: deleting an authored value does not remove
it if something supplies it silently, and authored/ is where a reader looks and
does not find it. Swept both halves of what I own.
GDScript: every keyed lookup with a fallback, cross-checked against the 121 keys
present in authored/. One hit -- exit_ramp_units, the case already fixed -- which
makes it the sweep's own positive control: the detector found the known instance
and nothing else. The other numeric fallbacks are identity or sentinel and invent
no quantity.
Exporter: 14 serde(default) sites, all attaching to Option, Vec or map types,
where an absent key becomes None or empty and asserts nothing.
My classifier produced a false positive I nearly wrote up: it flagged
also_export: AlsoExport as a semantic default because the type name lacks a
container prefix. AlsoExport is a type alias for a BTreeMap. Classifying a type by
the spelling of its name is the same proxy reasoning as inferring an era from a
line count.
Negative result, but from a check that demonstrably finds the known case.

ScreenView.exit_ramp_units defaulted to 24.0 -- the constant HANDOFF ask 2 told
this port to author and that it refused, since the file's own ramp is 10 units.
The authored entry was deleted as progress when the corrected record layout
removed the unknown, and the default plus boot.gd's timing.get(..., 24.0) made
that deletion a no-op.
Both use sites are unreachable on today's export (866 keyframes, 0 untimed), so
the branch is kept for an older export but no longer invents: the default is -1.0
meaning not supplied, and an untimed group now raises an error naming the screen
rather than fabricating a duration.
My first verification accused the change: main_menu 641941 px and extras 226009 px
changed, on a branch that cannot execute and with no error raised. The cause was
--screen=X --capture= firing at an uncontrolled instant -- t=9.00 in the earlier
run against t=8.00 in the later one, one unit apart mid-build-in. Three runs now
are byte-identical, so it is not noise; the instant is stable within a session and
moves between them. Re-run with --time=1.0 pinned, old against new is
byte-identical on all four screens.
Records the harness limitation: --screen=X --capture= cannot be used for
before/after comparison on an unsettled screen, which also explains the earlier
settle-vs-rest confound.
Also corrects my overstatement that other tools call the CLI -- verify-screen is
the only one, checked.

Told the Decoder their diagnosis was wrong. They were right. ui_layout.rs is md5
b6c19d08 in my working tree, at HEAD, on my pushed branch and on origin/main --
one file, stale marker present, tree clean.
What misled me is the same trap a third time: CARGO_TARGET_DIR is a shared
/sylph-home/port/target-container, so two source trees write one binary and cargo
fingerprints per source path -- each build reports Finished while the binary on
disk belongs to whichever tree wrote last. A CLI built from my workspace is
3a39fce (stale, rest t=70), identical to one built from origin/main; the binary
verify-screen actually used was 8e0aa76 (fixed, rest t=12), from a tree nobody had
named. It happened to be the right era, which is worse than wrong -- it agreed
with the pin by luck and one rebuild would have flipped it silently, and title_jp
differs by 74507 px between eras.
verify-screen now reads the reference CLI's pteff00 rest instant and compares it
against the export the port reads, refusing to score if they disagree. Controlled
both ways: passes with the matching binary, refuses the stale one built from my
own workspace.
And the pin is load-bearing, not an annoyance to revert: the workspace crate is
stale, so the pin is the only reason the export is correct. Consequence worth
stating -- my published branch carries the stale crate, so anyone building
sylpheed-cli from it gets the stale decoder.

Last iteration I overturned check-all's allowance on a measurement of 0 pixels
between the two decoder eras, and rewrote the tool's reason around it. The two
binaries had the same md5: one built in a worktree at formats-pin-2026-08-30 and
one from the workspace, and both commits carry the record-layout fix. I compared a
binary with itself and reported the zero as evidence. The 508-line diff I cited
was real and irrelevant -- it does not straddle the fix.
Done properly against origin/main, verified stale by the Decoder's own control
(rest t=70 vs rest t=12) and by differing md5s: title 0 px, main_menu 0 px,
title_jp 74507 px -- reproducing their figure exactly, under their flags and mine.
My second hypothesis, that --animated masked it, was also wrong.
What survives: the era still cannot explain this script's rows, for a fact I had
not established -- both sides of the comparison are the FIXED era, since a binary
built from the pin and one from the workspace have the same md5. Right answer,
wrong evidence. The note now carries its condition: title_jp is era-sensitive, so
if the reference is ever built from a different era than the pin, that row's cause
changes.
Twice now a correct conclusion has come through a broken experiment, and both
times the tell was two things that should differ producing identical output.

They answered ask #2 -- the gap is deterministic, not a load -- and held me to
re-stating the choice against four measurements (0, 6, 4, 6) rather than the three
it was made on. That is my own standard for check-all's stale allowance turned
around.
The arithmetic moved against 0: it costs 2.0x the best fit on four measurements
against 1.7x on three, and is now the minority outcome, wrong on 3 of 4 where a
uniform 6 is wrong on 2 of 4.
Still 0, because the reason was never the fit -- it adds no black the game does
not have, and is measured-correct for a real transition rather than for an average
of them. Picking 6 because it appears twice is choosing a mode from four samples
when their finding is that a rule exists and nobody has found it.
But one leg is gone and is not being kept quietly: part of the case for 0 was that
the quantity might be machine-dependent and unauthorable. It is not. That removes
an excuse without supplying a value.
Added a tripwire: if the gap is non-zero in most transitions and no rule emerges,
omitting a real quantity stops being caution and becomes a different invention.
The port is wrong by 4-6 units on three of four known transitions and the why now
says so.
Also records as settled: the outgoing ramp is the declared final ramp, my {8,10,10}
against their measured multiset, two independent routes.

The Decoder measured the black gap on three transitions: menu->title 0 units,
title->menu 4, EXTRAS->menu 6. Not a constant, and 9 was outside the range
entirely -- wrong for all three by up to a sixth of a second of black the game
does not show.
Did not take the best-fitting value. A uniform 4 minimises total error (6 against
0's 10); that is fitting three samples. 0 has a reason that is not a fit -- it
adds no black the game does not have, the tie-breaker input_during_transition
already uses, and it is measured-correct for one real transition. The error is now
a missing gap of at most 6 units on two transitions rather than an invented one of
up to 9 on all three. Boot artifact unchanged at 0.0009% differing.
Their EXTRAS run vindicates the earlier refusal: B from EXTRAS goes black for two
completely empty frames, so the two-line change I declined would have been wrong
for two of three transitions.
Also: the declared final ramp is confirmed from my side (title 8, main_menu 10,
extras 10 -- their exact multiset), needing no constant. And exit_ramp_units
defaults to 24.0, the number HANDOFF told me to author and I refused, on a branch
that cannot execute: 866 keyframes across 16 screens, 0 untimed.
And origin/main is the stale era -- verified 0 145 left-right, tip 2026-08-29,
still carrying the pre-fix association. The per-iteration merge has been a no-op
for days, its 'Already up to date' reading as 'I am current' while meaning 'main
has nothing'.

The suite reported '2 DIFFERS, allowed: the pin is not on main, so this compares
two decoder eras', and I had quoted that for several iterations without testing
it. Built sylpheed-cli at formats-pin-2026-08-30 and at workspace HEAD and
rendered through both: title, title_jp and main_menu come out 0 pixels different,
despite 508 lines of difference in ui_layout.rs. The eras are not the cause, and
the allowance was excusing a real signal with a wrong explanation.
A second defect in the same eight lines: the expiry tested formats-pin-2026-08-29d
while Cargo.toml pins formats-pin-2026-08-30, so it would have expired on a tag
this tree does not use.
The real reasons are per-screen and already documented: title is the ptloop sweep
phase residual, title_jp is the --pose=rest sparkle handling -- where the port's
shipped pose scores +0.9994 against the game to the reference's +0.8727, so the
port is closer to the game on the row the script calls a disagreement.
Replaced with a named set: title and title_jp by name, any other DIFFERS fails.
A count cannot notice a different screen drifting while the total stays at two.
Controlled both directions -- passes on the known pair, fails on main_menu or
extras. The pin reminder now reads the tag out of Cargo.toml so it cannot drift.

First end-to-end pass I have actually seen: all six asserting checks ok, oracle
captures at 0.00-0.35%, verify-screen's 2 DIFFERS allowed for its stated reason.
My two earlier attempts produced nothing -- one killed by my own timeout with
block-buffered output, one wedged by the ffmpeg hang -- while I reported 'still
two lines, both ok' for three iterations. I was treating absence of output as
patience.
Their discriminating test holds, prediction written down first: incoming build 4
gives an 8-frame decay, build 5 a 5-frame one against my predicted 6. Their tell
reproduces from my export independently -- main_menu settled is [64], title's
opening pair is [255,64], composite [64,255,64], and no single element produces
it.
The consequence neither of us predicted: A title->menu is sequential with a real
~5-frame black interval, B menu->title has NO black interval -- the incoming title
draws at frame 34, before the outgoing quad ramps at 40. boot.gd applies
black_hold uniformly, so the port inserts ~9 units of black on B that the game
does not have.
Not changed. One run of one transition is exactly the generalisation they just
named as the error under two of their own wrong readings, and their second caution
is that the A figure may be a load rather than a designed hold. Recorded as a
known, stated divergence with a BLOCKED ask.

The Decoder declined to let their measurement confirm my black_hold_units, and
they are right. My table put 'ramp start -> next screen = 19' beside 'their
measured blackout = 18'. Theirs runs content-start -> fully-black; mine runs
ramp-start -> next screen. Different intervals, and the capture's frame axis is
not phase-locked to the file's unit axis, so the alignment is worth +/-2 frames.
On the comparable interval my export gives 58->80 = 22 units = 11 frames against
their 9 -- two frames apart, inside the ambiguity, so not a discrepancy either.
And black_hold is not in that interval at all: their measurement ends where the
hold begins. It neither confirms nor refutes the 9.
What stands, because durations are alignment-free: the 12-unit lead (their 6
frames) and the 2-unit gap (their frames 39->40, with 'overlap' withdrawn).
9 now sits as authored-and-consistent, not confirmed-by-measurement.
Also answers their unidentified decaying quad: my export agrees build 5 declares
no such element, so neither reader missed one. Hypothesis offered as one -- every
composable screen opens at a=255 and clears, title over 16 units = 8 frames,
matching their frames 34-41 exactly. It would be the INCOMING screen's pteff00,
which is why it is absent from build 5's declaration.

Two warnings. The first does not reach me: nothing is authored from
screen-transitions.md's 0.87/0.97/4.08 s spans, and nothing in this port reads
keyframe times outside the crate -- their stale fade_quads.py failure mode cannot
occur here by construction.
The second is about black_hold_units: 9. Testing their structural claim on my
export: pteff00 on main_menu is [0:a255 12:a0 70:a0 80:a255], rising to black over
70->80, while content fade-outs start at 58-60. That is 12 units of lead, exactly
six frames at 30 Hz, matching their measurement off the running game -- disc and
capture agreeing by independent routes. They say the two overlap; mine has a
2-unit gap, one frame, inside their stated resolution.
The arithmetic: quad ramp 10 units + my authored 9 = 19 units = 0.317 s against
their measured blackout of 18 units = 0.30 s. One unit apart, inside their own
resolution. The measurement that withdrew the 14 supports my 9.
It survived because I declined to author the 14 when the arithmetic was available
and fit -- I wrote that it was arithmetic rather than a measurement and left the
value where it had been measured. Had I adopted the composition I would now carry
24 units against a measured 18, which is the dead black they are warning about.
Not adjusting 9; one transition, one run, +/-1 frame.

The Decoder found the ordinal/entry divergence is disc-wide (21 of 24 archives, 18
at ordinal 0) and that GP_TITLE is the mildest case on the disc, the only archive
whose first ten ordinals are the identity. That is luck, not design.
No exposure here, checked: the four archives they flag appear in flow.json with no
numbers at all, screen_names.json already says LOCATED BY ENTRY INDEX, and every
tool of mine passes --all.
Verified the high ordinals where GP_TITLE's identity would break first, since my
export addresses 13 and 14: publisher twins 10 vs 13 at RMSE 3.06, developer twins
11 vs 14 at 4.33, against a control of 47.91 for two genuinely different screens.
The addressing lands where HANDOFF says the entries are, and the control shows a
mismatch would have been caught.
The constraint is recorded for whoever exports those four archives; the absence of
exposure is a fact about what I have exported, not a property of the tooling.
Also corrects my own wording: I called ptlogo_all_eff a '50% glow'. What is
measured is the plateau -- that it is a glow rests on kind 0x3000 and a 200% scale
that nobody has put in front of the running game. The mid-ramp correction stands
on the numbers alone.
