port: delete exit_ramp_units, invert the format's own rule, and guard a scale-0 leaf
FOUR THINGS, and the first is what MISSION section 3 calls the measure of
progress.
DELETED `exit_ramp_units` AND `exit_ramp_seconds`. They were authored because the
disc had no time slot on a group's final keyframe, so the ramp into it was the
one unknown duration per screen. Under the corrected record layout that keyframe
does not exist -- a group is an 8-byte header then frames x {u32 time; 36-byte
pose} and every pose is timed. VERIFIED DEAD BEFORE DELETING: setting it to 9999
(166 s) moved the boot's transitions by 0.04 s, which is wall-clock jitter, and
both uses in ScreenView are gated on a condition that no longer fires on any of
the export's 866 keyframes.
INVERTED THE FORMAT'S OWN RULE. `check.rs` enforced "the final keyframe has no
`t`; the disc has no time slot there" and FORMAT.md stated it. Both are now
backwards, and the validator fired 150 times on a re-export. I had not run
`check` between pinning the tag and measuring against the oracle -- the pixel
harness was green while the format validator was failing on every screen with a
multi-keyframe group. A correctness harness does not replace a format one; they
fail at different layers.
GUARDED A SCALE-0 LEAF, which the Decoder hit in its own renderer: its leaf
branch marked the element drawn unconditionally while the blit returned early on
zero scale, so a scale-0 leaf suppressed its parent and blanked the element --
live on all four loading screens. This port did not have the bug only because
authored/rendering.json happens not to list pgloading_loop5. That is an accident
of a gate written for another reason, not a defence, so `_draw_leaf` now reports
whether it drew and `_draw` falls back to the parent.
ISOLATED THE PACING QUESTION rather than leaving it as a suspected regression.
Legacy association: publisher 4.70 agrees, developer 3.92 DIFFERS. Corrected:
publisher 4.26 DIFFERS, developer 3.62 agrees. Both misses are ~0.03 s outside a
composite bound. The association traded which screen is marginally out; it did
not regress the pacing.
Bumped the pin c -> d for the parser and audio changes. Its headline renderer
change does not reach this port: sylpheed-cli builds from the workspace crate.

port: the 11.5 px was the fit's resolution -- and the lesson inverts
The Decoder closed it by ADDING OBSERVABLES, not by tuning. The vertex buffer carries positions and colours at the same instant, so all four quantities must agree on one t: quad A x solves to 357.88 and quad B x to 357.58, both +/-0.12 units, against 355.75 +/-1.54 and 354.09 +/-1.89 from the alphas. Alpha moves only 0.27-0.33 levels per unit, so one byte of quantisation is worth 1.5-1.9 units -- 6-8 px of sweep at 4 px/unit. That is the whole of the 11.5 px. At t=357.7 the centres land within 0.70 px and both alphas inside one level. THE LESSON IS THE EARLIER ONE INVERTED AND IT IS THE HALF WORTH KEEPING. Checking a wrong rule against alpha made it look confirmed; here the same insensitivity MANUFACTURED a residual that did not exist. An insensitive quantity does not merely fail to falsify -- it invents error. Solve on the fastest-moving field, check the slow one, never the reverse. I was already looking for a pivot rule to explain 11.5 px when they wrote; there was nothing to find. REFUTATION ATTEMPT, survived with a nuance: they state the leaf pivot is (200,90) on a 399x180 sprite, "the pivot is the centre, so rotation displaces it by nothing". Checked against my export -- pivot [200,90], sprite 399x180, true centre 199.5,90. It survives, but the sprite is ODD-WIDTH so the pivot is the centre to within half a pixel rather than exactly. No consequence against their 0.70 px agreement; worth stating because "displaces it by nothing" is the kind of sentence that later gets leaned on for a sub-pixel claim. verify-capture now poses the title at t=357.7 rather than 355: RMSE 21.07 -> 20.92, differing 1.82% -> 1.81%. Marginal, and it is the right pose for a stated reason rather than a better number. AND ptlogo_eff2 IS WITHHELD FOR A BETTER REASON THAN MINE. I had it on caution about untested generalisation; the Decoder points out it is on title_jp and MISSION section 7 scopes out "localisation beyond English", so it is not a question this port has to answer and the parked Japanese capture does not need reviving for it. authored/rendering.json now gives scope first and undecidability second. Widening scope to close a residual would have been the wrong trade.

port: pin formats-pin-2026-08-29c -- the knob I tested last iteration was retired
I tested the wrong switch. SYLPHEED_KF_TIME_SHIFT is a superseded partial fix: it
got the association right but LEFT POSE 0 UNTIMED, which is exactly why the
untimed keyframe appeared to move from last to first. The real correction is the
DEFAULT in the tagged crate, with the old reading behind SYLPHEED_KF_TIME_LEGACY.
So last iteration's five rows measured a mismatch against a knob nobody should
use -- I suspected they were not decisive, I did not suspect the knob was retired.
THE CONSEQUENCE IS MUCH SMALLER THAN I BUDGETED. A placement group is an 8-byte
header then frames x {u32 time; 36-byte pose}, so pose 0's time is the group's
lead-in word and every pose is timed. Measured on the re-export: 866 keyframes,
0 untimed. `pose_at`'s "the final keyframe carries no t, so give it a synthetic
time" premise does not invert, it DISAPPEARS -- dead code rather than wrong code,
which is why nothing needed re-deriving. And the leaf now reads t=0 x=-639,
t=150 x=-39, t=540 x=1521, giving x=781 at t=355: the Decoder's predicted
top-left, and the 1300 px discrepancy is gone.
Pinned by tag, which is what MISSION section 2's tagging rule is for. BLOCKED was
wrong in both directions -- "cannot be taken yet" AND "only when that branch lands
on main". It arrives when the tag is pinned.
COST STATED: sylpheed-cli builds from the workspace crate, so until this reaches
main the exporter and the reference renderer read different decoders and
verify-screen compares two eras. verify-capture is unaffected -- it compares
against oracle captures and never touches the CLI. Revert to the path dependency
when the tag is an ancestor of main.
Oracle: publisher_logo 1.00% -> 0.75%, developer_logos 0.39% -> 0.33%, and
extras' differing region COLLAPSING from 736x525 to 398x295 at the sweep position
-- the residual localised onto the one element still in question. title unchanged
at 1.82%, now posed at t=355, the Decoder's FITTED sweep time. t=390 measures
1.65% and picking it would be fitting the pose to the score.
REFUTED, MINE: "ptlogo_eff2 is the single drawn element at a scale that is not a
whole multiple of 100%". That census was parents-only; the 45 leaves hold
thirteen distinct non-whole-multiple scales and 125% is among the rarest at two.
The claim's real content was "the only one the port draws" -- about my element
set, not the disc.

port: re-run the P5/P6 gate, and verify the cues with a null control rather than a detector
The leaf path, the plate pulse, the BGM level fix, the voice export, the focus fix and a diagnostic flag have all landed since the gate was last run. I had been verifying pieces against captures without once re-running the whole walk, which is the mission's actual test. It works. Nine steps unattended: down x4 through all five buttons, (A) into EXTRAS, (B) back to main_menu with FOCUS RESTORED to ptbtn05 (HANDOFF Q5's rule, live), up, (A) on OPTIONS which prints the archive gap rather than pretending. Every shot non-blank. Filmstrip shared as 1788027380-788b1faafc3e. THE SOUND IS VERIFIED BY A NULL CONTROL, NOT A DETECTOR. I first tried counting sharp level rises: it found ONE onset in the walk and THE SAME ONE in the music bed alone, which contains no cues -- a 50 ms envelope cannot see a short cue over the bed. The right response to a detector that cannot separate its control from its subject is to stop using it, not to widen the window until the numbers look better. So the technique that settled the voice: shadow the three cues with silence through data/mods/, run the identical walk, compare. cues playing peak +0.0003 dBFS RMS -18.36 cues silenced peak -4.74 dBFS RMS -20.78 Silencing three sound effects costs 4.74 dB of peak and 2.43 dB of RMS, and the walk's peak is SET BY a cue rather than by the music. The mod log confirms exactly three files shadowed. No detector, no threshold, and the control is the same run with one input changed. Recorded under the Dummy driver. It shows the cues reach the Master bus at the right moments; it does not show they are the cues the game plays -- that is Q8, and authored/audio.json still carries the offsets as measured.

port: the -324 was the old keyframe association, and the corrected one was available all along
The Decoder found it and it is not geometry: my leaf path pairs each pose with the NEXT pose's time. Fed my pairing into its own interpolation it reproduces -324 to the digit; corrected, t=355 gives centre 980.5 against 992.0 measured. So there was no 1300 px pivot mystery, and saying both numbers rather than hunting one is what surfaced it. CORRECTING BLOCKED: this was never gated on a branch landing. The row said the change "cannot be taken yet ... reaches the port only when that branch lands on main". Wrong -- ui_layout.rs in this checkout carries the corrected association behind SYLPHEED_KF_TIME_SHIFT=1 and has all along. I read that file twice this session, once for rotation_deg and once for the leaf note, without noticing the switch. Ran the experiment. Re-exported under the shift and asked the oracle: publisher_logo 1.00% -> 0.75% better developer_logos 0.39% -> 0.33% better title RMSE 21.07 -> 20.41 better (area 1.82 -> 1.86, worse) main_menu 0.06% -> 0.10% worse extras 0.20% -> 0.24% worse NOT DECISIVE, and the reason is the point: under the shift the untimed keyframe moves from LAST to FIRST, while `pose_at` is written around "the final keyframe carries no t, so it is given a synthetic time exit_ramp_units after the last timed frame". The numbers measure a renderer/association mismatch, not the association. Adopting it means re-deriving exit_ramp_units, settle_units, spin_period_units and the plate against a layout where the untimed frame is first. Export reverted to the default; doing that work hastily is how a 1.8% gap becomes five wrong ones. THE METHODOLOGICAL POINT IS THE DECODER'S AND IS THE BEST THING HERE: its rule matched because alpha at t=355 sits inside a long segment where a one-keyframe shift barely moves it, while x sweeps 1560 px over the same span. It confirmed on the insensitive quantity, I was wrong on the sensitive one, and neither of us saw it until they were compared. CHECK A NEW INTERPRETATION AGAINST THE FASTEST-MOVING FIELD YOU HAVE, NOT THE ONE THAT HAPPENS TO AGREE. That is a control chosen where it could not fail, which is a different failure from the uncontrolled instruments this session has collected. An 11.5 px residual is left and is not to be fitted.

port: implement the decoded leaf composition -- and it does not close the 1.82%
The Decoder decoded the rule I refused to guess: draw the leaf on its own timeline, do NOT multiply the parent's alpha in. Multiplying is refuted rather than unsupported -- at the fitted time the parent has expired, so leaf x parent predicts zero for both quads and the sweeps would be invisible. They are drawn. Implemented: `_draw_leaf` runs the leaf unclamped, like the spinning ring and for the same reason -- held at its own rest.t the leaf sits at x=1521, entirely off the right edge, so `holding` would delete the sweeps rather than settle them. AND IT CHANGES NOTHING MEASURABLE. The title is still 1.82% against the oracle: 1.82 at t=261, 1.81 at t=355, 1.79 at t=420. At t=355 my interpolation puts the leaf's top-left at x ~ -324, off-screen left, where the Decoder's model puts the quad's CENTRE at 981. Those cannot both be right, and it is not something to tune away -- it is a disagreement about how the leaf's keyframes become a placed quad, most likely in the pivot and the rotation about it. Handed back with both numbers. So: the exporter no longer drops the data, the composition rule is implemented as decoded, and the port's largest oracle gap is exactly where it was. Fixing the export was necessary and not sufficient. TWO FLAGGED ELEMENTS DELIBERATELY NOT DRAWN, in authored/rendering.json with reasons. title_jp/ptlogo_eff2 (parent 125%, leaf 100%) is the same shape and is the element DECISIONS has recorded since P1 as the largest render disagreement -- but the Decoder said plainly "I have not tested it", and drawing it would extend a decode past the case it was fitted on. pgloading_loop5's leaf is scale (0,0), and scale-0 is one of the three historical failures this corpus names. Neither can be adjudicated here: title_jp has no oracle capture, and verify-screen compares against a renderer that draws no leaves at all, so ANY leaf drawing increases that divergence whether right or wrong. Its max went 155 -> 232 when they were drawn, and that number is not evidence in either direction.

port: the exporter never opened an element's own .rat leaf -- 45 elements, and the title's 1.82%
The Decoder overturned the elimination I was most confident about. I ruled out
the ptloop sweeps because "399x180 at (441,270), keyframes hold position
constant". That is the PARENT's record. The geometry is in the leaf.
ptloop01 parent: scale (100,100) rot 0, fixed at (441,270)
LEAF: scale (100,600) rot +30, x sweeping -639 -> -39 -> 1521
ptloop02 parent: scale (100,100) rot 0, fixed at (441,270)
LEAF: scale (100,800) rot -45, x sweeping 1721 -> 1111 -> -839
Two ~1080 and ~1440 px quads leaning opposite ways and sweeping across the frame,
against two 400 px sprites drawn upright and static in the middle. That is
exactly the signature I measured -- darker centre-left, brighter right, nearly
cancelling -- and the GPU capture puts their centres at x ~ 467 and 992, the two
cells where my signed difference peaked.
`ui_layout`'s own doc comment said it: "the rotated quads come from its two
nested .rat leaf records, which the census never opened". Neither did this
exporter -- it opened a leaf in exactly one place, `highlight_name`, for focus
records.
IT IS NOT TWO ELEMENTS, IT IS 45: every button on every menu (the benign case,
where screen.rs already knew the leaf duplicates the parent and the parent wins),
the four loading screens' pgloading_loop*, and title_jp's ptlogo_eff2 -- which is
the element DECISIONS has recorded since P1 as the largest render disagreement in
the export, and which has a TWO-element leaf. A lead, not a conclusion.
EMITTED, DELIBERATELY NOT DRAWN. One `read_leaf` closure serves both the new path
and the focus path, because a second copy is how this would go missing again.
ScreenView ignores the data: parent and leaf each carry their own alpha ramp over
a different span (parent 0->255 over t=70..238, leaf 255->0x80->255 over
t=150..600), so how they compose is a decoding question, and drawing on a guess
would replace a visible 1.82% gap with an invisible wrong one. verify-screen
confirms nothing moved.
Additive blending is refuted -- the Decoder tested T8aD +0x04 bit 0x02 and "every
measure worsens", and the export carries no blend field because none has been
found (no RB_BLENDCONTROL in the per-draw capture). My hypothesis from last
iteration is dead.
This makes the port's biggest oracle gap the same item as the rotation question
already standing with the human: sylpheed-cli deliberately does not rotate, which
is why both renderers show it, and MISSION's "Needs a human decision -- rotation"
now has a number: 1.82% of the title's pixels.

port: S00A is closed as not obtainable, and Q5's shape is tighter than "unstable"
Three things folded in from the Decoder, none of which change the export. S00A IS NOT OBTAINABLE HERE and it is the game that stops it, not the drive. The drive works end to end -- main menu +0.999, newgame-difficulty +0.999, newgame-selectdata-crash +0.997, with the focus detector validated live against a known transition rather than trusted -- and then the guest throws at PC: 0x82307128 x349 with no S00A stream ever decoding. Recorded in BLOCKED as a route finding, with the consequence for me stated: THE CENTRE-CHANNEL RESULT RESTS ON ADV ALONE. S00A was wanted precisely because its second stream is digital silence where ADV's is a 0.60x copy. Q5 GAINED TWO POINTS and the shape is sharper than "it varies": TUTORIAL x3, NEW GAME x3 over six boots, and no other item ever observed. That does not change the port's authored initial focus -- NEW GAME is still one of exactly two observed states and is the state of the committed capture -- but it changes what would REFUTE it, so the authored `why` now says so: a boot opening on LOAD GAME, OPTIONS or EXTRAS breaks the two-way shape, and a rule predicting the split deletes the entry outright. `which-focus` NEEDS GODOT AND THE EXPORT TREE, so it cannot run in the RE container. Recorded in its own header rather than left for the next agent to discover, along with the pointer to the capture-only alternative and that tool's own caveat: its offline controls are its calibration inputs, which is self-consistency and not validation.

port: the title residual is a horizontal redistribution, and three of my own explanations are dead
`title` is the port's largest disagreement with the oracle at 1.82%, and last iteration I attributed it to the moving ptloop sweeps without checking. Wrong, and so were the two hypotheses I formed after it. NOT THE SWEEPS. ptloop01/02 are 399x180 at (441,270) -- small and central -- and their exported keyframes hold pos, scale and rotation constant. The difference peaks at x~1088. NOT AN OVER-HELD ELEMENT. Added `--no-hold` to render the alternative: playing the title's groups past rest fades the screen to black by t=5.2 s, 30.97% differing against 1.82% held. Holding at rest is right. NOT A TIMING OFFSET. Sweeping the build-in gives 24.05% at t=1.6 falling monotonically to 1.68% at t=4.18 and 1.82% settled. The capture is at the settled end. WHAT IT IS: a horizontal redistribution. Signed difference by cell shows the port DARKER centre-left (-13.1, -8.3, -6.6) and BRIGHTER right (+16.0, +9.9), nearly cancelling -- whole-frame means 63.8 against 62.5. Brightness in the wrong place, not a level error or a tone ramp. It falls in the rows spanned by the two wide elements ptlogo_back2 (1118x262) and ptlogo_back2eff (1133x280), with the column profile falling off past x~1152 against their right edges at 1189 and 1197. AND THE EXPORT CARRIES NO BLEND MODE. ptlogo_back2eff's keys are declared, id, index, keyframes, kind_raw, layer, layer_source, pivot, rest, role, sprite -- there is no blend field, in this element or in FORMAT.md at all, and the port composites everything with normal alpha. If the game draws `_eff` layers additively, a wide gradient sprite would produce exactly this signature and nothing in the export would reveal it. Asked, not assumed; I have not tested it, and I am recording it because the three I could test are dead. Recorded and NOT acted on: pteff02's rest.t is 46, where its fade is 25% black, while its own group reaches 0x00000000 at t=236 -- so the port holds a black veil the timeline removes. Third instance of rest.t naming a hold that is not the settled state. It does not explain the residual: removing a darkening veil would make the port brighter still, and it is already brighter where it disagrees. `--no-hold`'s first version set the flag thirty lines before `view` exists and silently rendered nothing, caught because the loop found no files rather than because anything reported an error.

port: which-focus -- a focus detector for the Decoder, with the control wired in
S00A is blocked on knowing which button a screenshot has focused. `newgame_path.sh` assumed NEW GAME at boot, drove on it, and landed in a tutorial mission -- HANDOFF Q5 measured focus as UNSTABLE across boots. Counting presses cannot substitute: up from the first item wraps to the last, so no fixed number of presses lands on a known item from an unknown start. The Decoder's own attempt, a per-row brightness statistic, FAILED the control -- it picked NEW GAME on the capture whose filename says OPTIONS. The render-difference method passes it, so this packages it as a script. IT RUNS THE CONTROL ON EVERY INVOCATION, not once when it was written, and refuses to report anything if the control fails. live-main-menu-options-focused KNOWN ANSWER OPTIONS 4.7x live-main-menu the question NEW GAME 11.4x live-extras KNOWN from corpus MISSION SELECT 4.2x live-title-press-a no menu at all refuses 1.0x The extras row is a second known answer I did not plant -- authored/flow.json already records "MEASURED: EXTRAS opens focused on MISSION SELECT (live-extras.png)" -- and the tool reaches it independently. The title row is the negative control. AND THE REFUSAL NOW CARRIES A NON-ZERO EXIT CODE. The first version printed "do not act on this" and exited 0, so a caller scripting it -- which is the entire point -- would have read a refusal as an answer. Same defect as a checker claiming a check it skipped, and the fifth instance of that shape this session. What it is not: it identifies focus in ONE FRAME and says nothing about what selects focus. Q5's instability stands. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01N7FiFFFwbvG2uxdcEh8HyF |

port: the capture has NEW GAME focused, and my harness had been rendering no focus
The Decoder attached an honest caveat to its reproduction of the tone-curve
refutation -- its bins included the focus-state mismatch, so it was "not a clean
second opinion". Removing that caveat found a defect of mine.
IDENTIFYING THE FOCUSED BUTTON, with a known-answer control. Walking focus
through all five buttons and comparing each against a capture:
vs -options-focused vs live-main-menu
ptbtn01 NEW GAME 6351 531
ptbtn02 LOAD GAME 7087 7094
ptbtn03 TUTORIAL 6230 6237
ptbtn04 OPTIONS 1292 6364
ptbtn05 EXTRAS 6073 6080
The control picks OPTIONS by 4.7x -- the answer its own filename gives -- so the
test is trustworthy, and live-main-menu.png has NEW GAME focused by 11.5x. That
is what the port already focuses. Corroboration, NOT a decode: Q5's instability
stands (four boots gave TUTORIAL, TUTORIAL, NEW GAME, NEW GAME) and this
identifies one frame rather than a rule. Recorded in the authored entry.
THE DEFECT: `verify-capture` rendered menus with `--screen=`, which draws no
focus record, so it had been comparing main_menu to the oracle in a state the
oracle was never in.
main_menu 0.25% differing, RMSE 14.79 -> 0.06%, RMSE 13.21
extras 0.46%, RMSE 15.29 -> 0.20%, RMSE 13.38
A 4x improvement that was entirely my harness posing the port wrong rather than
the port drawing wrong. The first run of a new correctness harness reported a
discrepancy and three quarters of it was the harness.
AND THE DECODER'S CAVEAT RESOLVES TO NOTHING, measured rather than assumed:
re-deriving the transfer curve on the correctly-posed pair gives 1.20 / 1.26 /
1.18 / 1.10 / 1.03 / 0.94 at render 8..48, unchanged from the mismatched run. Its
reproduction stands as a second opinion after all.

port: build the correctness harness verify-screen has pointed at since P1
`tools/port/verify-screen` line 20 has said "use `tools/verify-capture` for the
correctness question" since P1, and there was no such file. The port has had a
harness comparing itself to sylpheed-cli -- two renderers sharing its assumptions
-- and none comparing it to the game, while its own docs said otherwise. That gap
is what ORACLE-CAPTURES.md warns about: this corpus has been bitten three times
by two renderers agreeing, and every one was obvious against a capture.
Five screens against framebuffer captures of the real game:
main_menu RMSE 14.79 0.25% differing focus state may differ
extras RMSE 15.29 0.46% focus state may differ
title RMSE 21.07 1.82% ptloop sweeps never stop
publisher_logo RMSE 10.77 1.00%
developer_logos RMSE 9.37 0.39%
NO SCREEN SHOWS A LARGE CONNECTED BLOB -- the shape a missing element makes, and
the shape all three historical failures made.
And 74.1% of main_menu's differing pixels fall inside the ORACLE'S OWN focus
signature (live-main-menu vs live-main-menu-options-focused, the same screen with
a different button lit). So the bulk of that disagreement is a state mismatch,
not a defect.
REFUTATION ATTEMPT, on ui-render-tone-curve.md's `capture = 255*(render/255)^g`.
It survives where it was measured and not past it. Binning every structurally
matched pixel by render level gives the relationship directly, and the implied
exponent is NOT constant: 1.26 at render 16, 1.10 at 32, crossing 1.0 near 44,
down to 0.69 at 96. Above ~44 the capture is BRIGHTER than the render, which one
exponent cannot express -- and that is exactly why my whole-frame fits kept
returning 1.00, the two halves cancelling. The page's own stated reach ("nothing
constrains midtones or highlights") was not a hedge, it was the finding. Its 1.49
for this screen measures 1.18-1.26 in my darks; recorded as a disagreement rather
than resolved, since they fit selected flat patches and I binned everything.
Two earlier versions of this tool reported a best-fit gamma and were wrong both
times -- once fitting across a 74% structural mismatch, once extrapolating past
the measurement's stated reach. The fix was not a better fit but a different
instrument: it prints the curve, which somebody can argue with.

port: stripping driver padding is exact -- the gate on S00A is cleared
The Decoder made this the gate on S00A and that was the right order: ADV plays itself on boot and can be captured with --gpu=null at 0.96x real time, but S00A starts ~4.5 s after (A) on a save slot, which needs a driven run, which needs screens, which rules out --gpu=null. So S00A is necessarily the 0.70x rendered route with ~10% additive padding, and is only worth a boot if stripping is exact. It is. A real music+SFX bed -- 137.37 s, carrying 454 genuine zero runs of its own -- had 1149 holes inserted at 8.37/s to +9.9% length, matching the observed ALSA profile, then was stripped and correlated in the low band: original vs itself r 1.000 lag 0.0 s margin +0.141 ceiling PADDED vs original r 0.436 lag -12.2 s margin +0.006 destroyed STRIPPED vs original r 1.000 lag 0.0 s margin +0.142 recovered stripped vs orig-also-stripped r 1.000 margin +0.143 Two things worth reading off that. Padding at that profile destroys correlation completely -- r 0.436 in the known-absent regime -- which independently confirms on a file whose contents I control that the earlier captures were unusable for the reason claimed and not for some other one. And recovery does NOT require stripping both sides: the stripped capture matches the UNSTRIPPED source at the ceiling, so the port's reference assets never need touching. `tools/port/strip-padding` implements it, and its header leads with when the operation is vandalism rather than with what it does: PulseAudio's monitor SUBSTITUTES silence and deleting those holes repairs nothing, while Xenia's ALSA writer PADS and removing that is exact. Running it on the wrong artefact would look like it worked. Its output is byte-identical to the control's own stripping, so the tool and the experiment are one operation rather than two implementations that agree. Not licensed by this: stripping removes genuine silence too and cannot tell them apart. Here the genuine runs total 0.71 s in 137 s and cost nothing measurable; on material that is mostly silence they would.

port: the oracle speaks -- the exported voice IS the game's centre channel
The Decoder's fourth capture is the first faithful one: --gpu=null takes the guest
from 0.70x to 0.96x real time so Xenia stops padding, and an ALSA `file` tee in
front of a paced slave removes PulseAudio's wall clock entirely. 59.7 s, 0.35%
silence, ONE gap in the whole file. Checked here rather than taken: it passes
check-capture, and its header sizes verify exactly.
The correlator was already calibrated, so this was a re-run and not a rebuild.
Controls on this instrument first: known-present margin +0.248, absent +0.005.
SPEECH BAND, margins by channel:
FL FR FC LFE RL RR
stream 1 (leading) +.013 +.006 +.012 +.009 +.012 +.005
stream 2 (EXPORTED) +.238 +.171 +.305 +.011 +.035 +.006
stream 3 +.240 +.173 +.307 +.009 +.054 +.006
r = 0.989 on FC, margin +0.305, above the known-present control. And the bed in
the low band is the mirror image: FL .763 / FR .838 / RL .805 / RR .817, all on
the same lag, FC .317.
SO: the dialogue is in the centre channel and the bed is in the four corners --
measured, where the header could never have said it, since ChannelMask reads
0x0002 on all three streams. And the port's exported voice file is the material
the game plays in FC: the `loudest` choice, which I recorded as unjustified,
selects the dialogue.
WHAT THIS DOES NOT SAY. Streams 2 and 3 are indistinguishable to this instrument,
exactly as expected from stream 3 being 0.60x stream 2 with the residual 26.8 dB
down -- so this does not say `loudest` picked the right one of the two, only that
whichever it picked is the dialogue. Stream 1 is undetectable here, consistent
with being stream 2's tail and a window that starts before it.
The `1 of 3 streams` warning STAYS: nothing here explains what the other two
contribute. What changed is its character -- from "one of three, contents
unknown" to "the centre-channel dialogue, plus two streams whose relationship to
it is measured and whose role is not".
Reach: 59.7 s of a 137 s movie, one run, 0.96x real time, and no screen
provenance -- --gpu=null costs video, so provenance is the XMA probe showing
ADV's three streams decoding during the run.

port: check-capture refuses a format it cannot read, and accepts the one it nearly rejected
The Decoder is moving to an ALSA `type file` tee, which writes float32. Read as s16 that yields a plausible-looking file whose only tell is per-channel peaks alternating exactly -- the two halves of each float landing in alternate channels. My parser assumed s16 throughout and would have mis-read it confidently. An unreadable format now ends the run at PARTIAL (exit 2) rather than PASS: channels were checked, starvation was not, and the tool says which. A checker that claims a check it skipped is the shape of every failure this file documents. AND THE FIRST VERSION OF THE GUARD WAS TOO STRICT -- it rejected one of this tool's own controls, a six-tone file `ffprobe` correctly calls pcm_s16le, because the file is WAVE_FORMAT_EXTENSIBLE (tag 0xFFFE) rather than plain PCM. A format guard that refuses a legitimate capture is the same defect as one that mis-reads an illegitimate one, pointing the other way. The check turns on wBitsPerSample, which is what decides the layout; a float tee is 32-bit and still caught. Control sweep, now the tool's real specification and all of it runnable here: real music+SFX bed PASS voice track, mono, 53% real pauses PASS six distinct tones, PCM and extensible PASS bed with 350 ms holes punched in FAIL the starved capture FAIL the same tones as float32 PARTIAL Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01N7FiFFFwbvG2uxdcEh8HyF |

port: the PRESS (A) plate pulses -- authored per element, because 82 of 212 share its shape
The human listed pulsation as first-class and the port drew nothing: the plate's focus record `ptbtn00f` was never reached, because press_start has no `buttons` and nothing is focused. That it LOOPS is measured -- the corpus timed the period four times (2.12 / 2.19 / 2.34 / 2.31 s) and you cannot measure a period unless the thing repeats. THE RULE I WAS GOING TO WRITE DIED IN THE CENSUS. The spinning ring is a rule in the renderer because it has a disc-wide check: 16 of 212 elements match its shape and all 16 are focus rings. The analogous shape for a pulse -- keyframes varying only in alpha, first alpha equal to last -- matches 82 OF 212, including ptcopyright, palogo_sqex, ptmsg and every _eff fade. A renderer rule on it would make the copyright notice pulse. Narrowed to focus records it matches exactly one distinct element, and a rule justified by n=1 is a special case wearing a rule's clothes. So it is a LOOKUP in authored/timing.json keyed <screen>/<element>, with the census recorded beside it so nobody widens it later. The period is 129 units -- the element's own group under the port's existing model: last timed keyframe t=105 plus the authored exit_ramp_units of 24. No new constant. 2.150 s at 60 units/s, 2.295 s at the ~28.1 fps the emulator presents, against measurements of 2.12-2.34. IT IS A CHOICE AND THE ALTERNATIVE IS STATED: restarting at the group's first keyframe (t=6) instead of 0 gives 123 units = 2.050 / 2.189 s, also inside the measured spread. Nothing separates them. t=0 is taken because it is where every other group starts -- consistency, not evidence. Verified the way the ring was, by bit-identity one period apart. 20 periods is 43.00 s = exactly 172 film frames: frames N and N+172 differ by 0-1/255, while the control a quarter-second off (43.25 s) differs by 58.7/255. On the held boot title the glow-box mean swings 26.0 <-> 37.7.

port: check-capture needed two numbers -- the rate alone passed a 50%-silent file
The Decoder found a blind spot in the bar I shipped last iteration. Raising the PulseAudio client buffer keeps cutting the gap RATE while total silence bottoms out and then doubles -- an over-large buffer starves in a few enormous holes instead of many small ones. Its 500 ms capture scores 1.3 gaps/s, better than a genuine music bed at 3.3, while being 50% silence. My 20/s bar passed it. Same shape as the level table that cannot see a duplicated channel: one number, blind to the failure next door. I did not set a bar on their numbers, because I do not hold those files and the last two bars in this tool were wrong precisely from being invented. Instead I built a control in that regime -- `bigholes`, a real bed with 350 ms holes punched in -- and set the rule from four controls I can run: real music+SFX bed 1.1% silence, 3.3 gaps/s PASS voice track, mono, pauses 53.2% silence, 0.3 gaps/s PASS bed with 350 ms holes 46.3% silence, 3.2 gaps/s FAIL the starved capture 35.6% silence, 30.9 gaps/s FAIL Rate alone cannot separate rows 2 and 3; silence alone cannot separate 1 and 3. The pair does: fail when >=10% is silent on every channel AND there is at least one gap per second. Real audio is either mostly not silent, or silent in a few long stretches -- not both at once. AND THE REGIME IT STILL CANNOT JUDGE IS PRINTED RATHER THAN PASSED. High silence with very few gaps is what a real voice track looks like and what an over-buffered capture looks like; nothing here separates them, so the tool says UNJUDGED and tells the reader to check against a known source. Inventing a bar for a regime with no control in it is how the previous two bars came to be wrong. A CONTROL THAT DOES NOT EXECUTE IS NOT A CONTROL: the tool returned immediately for single-channel input, so the mono voice track -- one of the four controls -- was never run through the check it was meant to control. Mono now skips only the duplicate test. Also recorded: the Decoder has withdrawn "the monitor-sink route cannot be fixed by configuration". A ~200 ms client buffer is worth a retry BEFORE anyone spends a session on a Canary rebuild.

port: make the dwell comparison repeatable, and record that the settle run is unanchored
TWO THINGS, and the first is that nothing needed changing. The Decoder withdrew one of the two legs under its settle-time run: the plate pulse period it had offered as proof the run was not slowed rests on one interval at a 125 ms sample rate, and re-picking the troughs gives 2.628 s rather than 2.369 -- an adjacent local minimum counted as a separate trough. It cannot resolve a real-time factor below ~7%. Nothing in the port moves, because the numbers that correction touches were already unauthored. Checked rather than remembered: grep over authored/ and port/scripts/ finds no 0.531 and no 0.482. The only build-in reference in the tree is the plate arithmetic t=118 -> t=238, 120 units, which is the anchored leg -- it agrees with three prior readings and with the disc's own declaration. I had declined those two as one-run figures the Decoder itself flagged, with the port already within ~0.1 s from the disc's keyframes. That reasoning now has a second, independent justification I did not have at the time: a few per cent of slowdown sits inside them undetected. SECOND: `tools/port/verify-dwell`. Last iteration's hand comparison refuted a red flag I had filed myself -- `rest.t` is the wrong settle landmark, but "everything the sequencer paces off it is therefore late" was false and I nearly re-paced screens that already matched the game to 0.05 s. That check existed once, in a transcript. Now it runs. Its header carries the trap it exists to prevent, because that is the whole point: a port's TRANSITION TIMESTAMPS and the oracle's VISIBLE SPANS are not the same quantity, and differ by the exit ramp plus the black hold -- about 0.6 s, the entire discrepancy. The same confusion cost this corpus 0.48 s on the plate delay. The bar is the oracle's own run-to-run spread plus one film interval. Three cold boots of the real game differ by 0.3 s, so agreeing more tightly than the oracle agrees with itself would mean nothing. The developer-logo span reads 3.50 s on the hand-run and 3.75 s here, one interval apart and both inside the bar -- the tool reporting its resolution rather than hiding it. The oracle's numbers are in the script as a labelled test fixture citing their RE document; nothing in the port derives them.

port: BLOCKED -- the voice row says the capture routes are closed and why
The row still asked for a capture through the PulseAudio null sink as the thing that settles it. Both routes are now closed: take 1 was corrupted by a channel-map remap, take 2 is starved by construction, and the monitor sink cannot be fixed by configuration -- it advances at wall-clock rate and substitutes silence. The route that works needs a Canary rebuild costed at a whole session, which is the human's call. Also records the withdrawal of the WMA-track concern: a starved file neither supports nor refutes it.

port: check-capture passed a file that was 36% holes -- it now catches starvation
The Decoder diagnosed take 2 as a STARVED capture and I verified it here rather
than take it on trust: 35.6% of frames silent on all six channels, 10482
alternating runs, median burst 13.5 ms and gap 3.9 ms, a 17.4 ms period at 57 Hz.
Their untruncated original reads 39.3% and 10595 runs; the difference is exactly
the truncation and every other number agrees.
So my rebuilt correlator was working correctly on a file that could not carry the
signal. The alarming reading it produced -- that the game may not play the .wmv's
WMA track, so ADV.ogv's audio has been wrong since P4 -- is NOT SUPPORTED by this
capture and is not refuted either. Withdrawn as a concern arising from evidence,
with nothing changed in either direction. It was the most expensive-to-act-on
hypothesis in the port and it came from a file that could not speak to it.
THE REAL DEFECT WAS MINE: `check-capture` tested only for duplicated channels, so
it cleared a recording that was 36% holes. A provenance check that passes the
artefact it was built in response to is not a check.
It now measures starvation, and TWO THRESHOLDS I INVENTED WERE BOTH WRONG:
counting exact-zero frames -- real audio crosses zero constantly, so a clean
voice track scored 5947 "gaps" of median 0.0 ms and was called starved. A gap
is a RUN, not a sample; only runs over 1 ms count.
gap count and median length -- a genuine music bed shows 454 gaps at a median
of 1.4 ms, because quiet 16-bit passages really are zero for milliseconds.
What separates them is the RATE: 32.9 gaps/s starved, 3.3 for a real bed, 0.03
for a voice track that is 53% pauses. Bar at 20/s, derived from those controls
rather than chosen and then justified. Controlled both directions: real stereo
bed PASS, six distinct tones PASS, starved capture FAIL. It also reports a `data`
chunk declaring 0 bytes -- what a file copied mid-write looks like, which is what
happened.
VOICE CHANNEL ROLES ARE NOT OBTAINABLE THIS SESSION. Both routes closed: the
monitor sink is starved by construction, and the internal tap at
SDLAudioDriver::SubmitFrame needs a Canary rebuild the Decoder has costed at a
whole session. That is the human's call, not an agent's. The port keeps authoring
with the known recorded.

port: the menu music was 3.52 dB quiet -- a bank header was being summed as a stem
Checking my export against the Decoder's declared XMA1 durations turned up a
defect of mine that has been shipping since P6.
`export_bgm` summed every sub-wave `media` returned and scaled by 1/n. Decoded
and timed, all three banks have the same shape:
BGM_103 sub-wave 0: 10300 B -> 0.009 s, peak -inf 1: 87.744 s 2: 87.744 s
BGM_102 sub-wave 0: 10300 B -> 0.009 s, peak -inf 1: 37.482 s 2: 37.482 s
BGM_001 sub-wave 0: 10300 B -> 0.009 s, peak -inf 1: 173.809 s 2: 173.809 s
Sub-wave 0 is DIGITALLY SILENT in all three, and 10300 B is 10240 plus a 60-byte
RIFF wrapper -- 10240 being exactly the bank header the Decoder's census
identifies. Counting it in the divisor put every real stem at 1/3 instead of 1/2:
3.52 dB on all the menu music since P6. Dropping a silent input is arithmetic,
not a decoding decision. Measured after: main_menu.ogg -7.69 -> -4.20 dBFS,
+3.49 dB against 3.52 predicted.
THIRD INSTANCE OF ONE DEFECT: a silent chunk in the voice sum, a silent channel
in the mono fold, now a silent sub-wave in the music sum. Each invisible to every
check except a level, and each time the divisor was computed from how many inputs
there are rather than how many carry signal. That is the shape, not the bug.
Closes a red row open since P6 -- "sound_bank_riffs returns three sub-waves where
Q10's census says two". The census was right, and this corroborates the Decoder's

port: my correlation instrument failed its own control -- the negative had to be re-earned
Take 2 is a good file: it passes check-capture (I re-ran it rather than cite the Decoder's run), carries a screen log, and was recorded with the sink's channel_map set equal to Canary's own. BEFORE REPORTING A SECOND NEGATIVE I ASKED WHETHER MY METHOD COULD DO THE JOB, by building a synthetic mix -- the bed plus the three voice streams -- and hunting the bed inside it. It failed: r=0.415, against the r>0.8 bar my earlier negatives were judged against. So the instrument that produced "the capture contains no ADV audio" could not have found ADV audio in a mix even when it was certainly there. That conclusion was right -- the Decoder's tone control proved take 1 corrupt independently -- but it was right BY LUCK and I reported it as measurement. The three controls I was pleased with tested that the method finds a clean signal in a clean reference, which was never the task. REBUILT AND CALIBRATED IN BOTH DIRECTIONS. Band-limit so the target dominates, then judge on LAG and MARGIN rather than absolute r -- r>0.8 is correct clean-against-clean and meaningless for a component in a mix. bed, 40-180 Hz in a mix containing it r=0.663 lag 0.0 s margin +0.111 bed, 40-180 Hz against a voice-only mix r=0.262 lag wrong margin +0.005 voice, 300-3000 in a mix containing it r=0.810 lag 0.0 s margin +0.248 voice, 300-3000 against the bed alone r=0.358 lag wrong margin +0.005 A 20-50x separation in the discriminating statistic. Written up as AUDIO-VERIFICATION.md section 6, retraction included. THE NEGATIVE NOW STANDS ON SOMETHING. All six of take 2's channels, against both targets, sit in the known-absent regime: margins 0.000-0.017, lags scattered from -72 to +255 s. Take 2 contains neither the movie's WMA bed nor the cutscene voice. Two captures, differently configured, the second provably free of the channel-map fault, with a screen log saying the movie was on screen, and neither carries either source. Handed back: a capture path still losing the mix, or the guest not emitting these sources during the movie, and only one side of the wall can tell those apart. If it is the second it reaches the port directly -- the export's movie audio comes from the .wmv's WMA track. Also noted: the message gives 253.3 s, the file is 318.539 s. The screen log agrees with the file, so it is a mis-stated number, but a length quoted in a provenance claim should match the artefact.

port: a capture must pass a provenance check before anyone analyses it
The 6-channel capture I spent an iteration refuting was corrupt, and the Decoder found the cause: PulseAudio remapping between two mismatched channel maps, where a 6-channel remap SILENTLY DROPS AND DUPLICATES. Its control -- six channels, six tones, same sink, same parec -- came back 400/3200/200/800/800/200 for an input of 400/800/200/1600/3200/6400. Two source channels gone entirely. So the negative was right, and the byte-identical pair I reported was the thread that unravelled it. Worth recording precisely, because it nearly went unreported: it began as an idle look at two channels whose peak AND RMS matched to six decimals, and it only became evidence because a coincidence at six decimals is cheaper to hash than to explain. `tools/port/check-capture` makes that check one command -- split the file, hash every channel, fail on any duplicate pair -- and AUDIO-VERIFICATION.md gains a section 5 saying to run it FIRST, every time, plus the two conditions the same incident produced: start the recorder before the process, and log what was on screen against the recording's own clock so a miss is diagnosable. Controlled both directions, because a checker nobody controlled is what this incident is about: six distinct tones PASS; the remap's own output pattern FAILS naming all four pairs; the corrupt capture FAILS on ch2 == ch5. THE KNOWN-BAD CONTROL IS THE POINT. All six of its channels report a peak of -18.063656 dB, identical to six decimals, while containing three duplicate pairs. A level check cannot see this failure. That is why the tool hashes rather than measures, and why the corrupt capture's "plausible per-channel levels" were never evidence. The tool says of itself that it is necessary, not sufficient. Withdrawn with the file, both the Decoder's: "all six channels carry signal", and the non-zero-surround observation offered as weak support for 5.1. Unaffected: the three-XMA-context concurrency result, read from the emulator's log rather than the audio path, on two independent boots. The corrupt file is dropped from the exchange so the next agent cannot pick it up and repeat the work. Nothing in the export changed.

port: the oracle capture does not contain the intro -- a controlled negative
The Decoder took the capture I asked for and described it as the full mix, the
movie's WMA track plus the three XMA streams. It contains none of them.
Envelope cross-correlation, sliding with overhang, normalised over the overlap,
minimum 30 s of overlap so a short window cannot win on an edge. Against the ADV
bed, against each of the three voice streams, against BGM_103 and against S00A,
every pairing is a PLATEAU rather than a peak: best-to-runner-up margins of
0.001-0.016. The margin is the number that matters, not r.
Three controls, because a negative from an uncontrolled instrument is worthless:
the instrument finds matches on this data -- bed vs bed r=1.000 margin +0.115,
voice stream 2 vs stream 3 r=1.000 margin +0.300;
my reference really is the movie -- the .ogv transcode against the disc's own
ADV.wmv, r=1.000 margin +0.114, so a miss is not my transcode;
drift is excluded -- a stretched playback would still match locally with the
best lag climbing monotonically, and 5 s windows give 4.95, 15.30, 119.35,
50.75, 29.35, 83.95 s, scattered across the movie.
WHAT IT IS has been handed back rather than guessed. It is 70 s of something,
all six channels carrying signal at RMS about -27 dBFS, matching nothing this
port exports. Diagnosing it is the other side of the wall.
One measurement that may help: split as 5.1, channels 3 and 6 are BYTE-IDENTICAL
-- same MD5, not merely the same peak and RMS. An exact duplicate pair inside a
six-channel surround output is consistent with the Decoder's own warning that the
6-channel frame is Xenia's hardcoded kFrameChannelsDefault rather than the
guest's request, and weakens any reading of that file as evidence of a 5.1 mix.
THE VOICE EXPORT IS UNCHANGED: still one stream of three, still marked red in the
manifest, the console line and authored/audio.json. A failed measurement should
change nothing, and what would have been wrong is treating an expensive recording
as an oracle because it was expensive.

port: the game decodes all three voice streams at once, and two baseline rows were comparing blank frames
TWO FINDINGS, one mine and one handed to me, and the second retires a premise I built on twice. THE P1 BASELINE HAD ROWS THAT PROVED NOTHING. `build_12` and `build_15` render pure black in BOTH renderers -- mean 0, max 0 -- so the difference is zero and `verify-screen` scored them `max 0 over3 0 OK`, the strongest verdict it has. Two of sixteen rows were comparing nothing against nothing. Worse than a missing test, because a missing test is visible in the count. Cause isolated by a control, not by reading: `build_00`/`build_01` are the same loading screen minus three elements and render fine (mean 1.913, max 214.5). The dressed variants add `pgloading_eff00`, a 1280x720 primitive resting OPAQUE BLACK at t=38 inside its own opening black hold, with no layer key so paint order puts it last. The rule I was about to write -- "rest.t before the last timed keyframe is the pathology" -- was killed by running the census first: 152 of 212 elements in this export have rest.t earlier than their last timed keyframe. It is the norm. What is actually unusual is the CONTENT, and its reach is one: `pgloading_eff00` is the only element in the export whose resting pose is a fully opaque full-frame quad. One instance is not a rule, so the renderer is unchanged and the HARNESS is fixed: a blank pair now reports BLANK -- both renderers drew nothing; this row proves nothing. `status` is untouched, so an unrelated DIFFERS still fails. THE VOICE EXPORT IS KNOWN INCOMPLETE. The Decoder booted Canary with --xma_param_probe and the game decodes ALL THREE streams CONCURRENTLY, in three XMA contexts whose byte sizes match the disc payloads exactly. So "three presentations of one take, pick one" is refuted by the running game and the question I had been arguing -- WHICH presentation -- has no answer. This one no census could have caught. Every measurement was right: the streams are equal-duration, one is silence, one is 0.60x another with the residual 26.8 dB down. The frame around them was wrong, and the file says ChannelMask 0x0002 on all three. It took the running game -- which is the mission's own sentence arriving in practice. BEHAVIOUR HELD DELIBERATELY. An equal-gain 1/n sum of channel pairs is not a downmix either -- MISSION section 6 pins an explicit matrix for exactly that reason -- and summing cost S00A 6.02 dB when one stream was silence. Swapping one guess for another on a message is what produced this entry twice. What changed is that the wrongness is now LOUD, because this failure sounds like success: one stream is clean audible dialogue. A top-level manifest warning per movie, the console line, and the authored entry all say `1 of 3 streams`. "They are 5.1" is recorded as the Decoder's HYPOTHESIS with its own counter-evidence attached, and nothing builds on it. What settles it is asked: a recording of the game's own output over ADV through the null sink, which turns channel roles into a fit against an oracle. Refutation attempt, survived: the Decoder's loading-screen variant map. Entries 0/1 carry 7 elements and 12/15 carry those seven plus baseeff, eff00 and loop5 -- exact in count and identity, and it is what made build_00 a control.

port: withdraw the dual-mono generalisation -- the measurement stands, the rule does not
I argued `highest_rate` had no case because ADV's higher-rate presentation is dual-mono while its louder one is mono-in-stereo, so the extra bytes buy a duplicated channel rather than fidelity. The Decoder tested that disc-wide over the 28 three-stream cues: the stream-3/stream-2 size ratio runs min 0.0778, median 1.2565, max 2.9163, sd 0.5057, with only 12 of 28 within 15% of 1.0, and declared rates scatter with them. A 37x spread is not a duplicated channel. The CHANNEL MEASUREMENT STANDS -- ADV chunk 1 is mono-in-stereo and chunk 2 is dual-mono at -8.318574, this port's own decode, which the Decoder could not re-run and did not dispute. What fails is the step from one asset to the format. NOTHING IN THE EXPORT CHANGES. `loudest` is a per-asset content rule -- it reads the peak of the streams in front of it -- so a scattering structural ratio cannot undermine it. What changes is the REASON, in four places: authored/audio.json's presentation_why, the selector comment in audio.rs, BLOCKED.md's row, and DECISIONS.md. The honest statement is narrower: `highest_rate` was never refuted, it was never argued for, and neither is `loudest`. That is why the entry is marked CHOSEN rather than measured, and why one capture deletes it. Recorded on the pattern rather than just the instance: this is the third claim of mine in two iterations that generalised a single-asset observation, after "the chunks are two stems" and "everything the sequencer paces off rest.t is late". All three were true of the thing I looked at. The failure is reaching for the rule a measurement would imply if it held everywhere and writing that down in the same breath as the measurement. Also noted, not mine and not affecting export_voice: S12B's three streams are byte-size identical, and BIRD_224 is three-stream while not being a movie cue.

port: settle times measured -- the pacing was already right, and my own red flag was half wrong
THE TRANSCODE CACHE HAD NEVER HIT. `video::transcode` has carried one since P4 -- a `.cmd` sidecar with the command, the source size and the channel count -- and `main.rs` clears the output tree wholesale immediately before the check, deleting the sidecar and the file it stamps. Six exports in this session paid the full Theora encode and produced five byte-identical files, roughly 48 minutes. Nothing reported it, and nothing could: a cache is silent either way and the only symptom is a wall clock that looks like the job being slow. The wipe now spares `video/` and `prune_videos` deletes anything in it this run did not claim, so the wholesale guarantee is kept rather than traded. A re-export is 20 s. SETTLE TIMES, MEASURED, and they refute more of my row than they confirm. The principle holds -- the title's rest.t is 251 units = 4.183 s where its art finishes at ~2 s -- but "everything the sequencer paces off that landmark is therefore late" does not. Measured the port the way the game was measured, by VISIBLE SPAN rather than arrival-to-arrival: publisher wordmark port 4.25 s game 4.297 / 4.604 / 4.370 developer logos port 3.50 s game 3.508 / 3.503 / 3.366 black hold port ~0.25 s game 0.2 - 0.3 title -> plate port 2.000 s (declared 120 units) game 2.247 s Dead on. My earlier reading compared the port's transition timestamps against the game's visible spans, which differ by the exit ramp plus the black hold -- the whole of the discrepancy I was about to chase, and the same definitional trap that cost this corpus 0.48 s on the plate delay. Nothing in the sequencer is changed. `dwell_seconds` stays null, now for a measured reason rather than an absent one: `timing.json` said "if a capture ever times the real boot, this is where that number goes", and the answer is that nothing goes there. Not authored, deliberately: an (A)->menu dwell, which measures 3.763 s and contains a 1.53 s guest load stall on a cold cache; and the menu build-in and (B)->title, which rest on one run where the port is already within ~0.1 s. THE VOICE PRESENTATION MOVED TO authored/, because the recommendation behind it was withdrawn as self-contradictory and the choice is now unambiguously mine. `voice.presentation` = `loudest`, and the reason to switch is a measurement, not a preference: ADV chunk 1 is MONO-IN-STEREO and chunk 2 is DUAL-MONO, so chunk 2's extra bytes encode a duplicate channel rather than fidelity. That explains the byte-rate difference and removes the only argument for `highest_rate`. ADV's dialogue now exports at +0.3 dBFS instead of -8.7, which is the SE bound's documented decode overshoot on a wave mastered at full scale.

port: a voice region is three presentations of one take -- keep one stream, sum nothing
Third reading of the same bytes in one session, and the first one that is
decoded rather than inferred.
1. concatenate -> 359 s of dialogue for a 137 s movie. Dead on measurement.
2. sum as Q10's two stems -> refuted here: S00A's second full-length chunk is
DIGITAL SILENCE and ADV's is 0.60x the first with 26.8 dB of residual. That
claim was mine, and the Decoder had already adopted it before I tested it;
it is withdrawn in both places.
3. keep ONE stream. Decoded disc-wide by the Decoder, counting stream starts
inside every inter-descriptor span: 258 spans hold one stream, 28 hold
three, nothing holds two. So 359 = 84.55 + 137.32 + 137.32.
Summing was therefore wrong a third time, and for a third reason: a take plus a
0.60x copy of itself is ~4 dB louder and coloured, not a mix of parts. The filter
is now `[0:a]anull` plus the mono fold -- no gain applied at all.
`check` moves `voice` off the strict peak bound as a consequence. It sat with
`bgm` because it was a sum this exporter produced; it is now a single wave off
the disc, mastered near full scale -- ADV's louder presentation measures +0.0003
dBFS at source -- so refusing that would be refusing the disc's own mastering.
The leading chunk is dropped as a DUPLICATE, not a truncation. It is this
movie's own dialogue (the Decoder, 17 of 17) and I measured it to be the TAIL of
the kept stream: sliding envelope correlation r=0.998 / 0.932 with the lag flush
against that stream's end, controls 1.000 self and 0.289 for a different movie,
confirmed in the sample domain at 16.7 / 23.2 dB of residual.
STILL OPEN, and flagged rather than absorbed: WHICH presentation to keep. Highest
byte rate is the Decoder's recommendation and not a decoded field, and on ADV it
selects the QUIETER of two (-8.3 dBFS against 0.0). Said in the manifest with the
consequence, so it is visible and reversible. A capture of the intro with
dialogue audible settles it.
Not converted, and the Decoder has since withdrawn the ask with a better reason
than mine: its 504464 B anchor constant is structural, not proportional --
identical on all 17 regions, and a proportional prediction lands within 8 bytes
on ADV while being 4305 B out on S00A.

port: fold only the channels that carry signal, and measure what the leading chunk actually is
TWO DEFECTS AND ONE MEASUREMENT, all from verifying the previous commit rather than from reading it. Channel 2 of both voice streams is DIGITALLY SILENT -- peak -inf over the whole file. The voice is a mono recording carried in a nominally stereo stream, and averaging it with silence cost 5.94 dB. The doc comment directly above the code that did it warned that "a stereo matrix applied to a mono voice track is not an error, it is a -6 dB attenuation that nothing reports", and then the code checked the DECLARED channel count instead of the content. `live_channels` now measures which channels carry signal and averages only those. Three defects this iteration were the same shape: a silent chunk in a sum, a silent channel in a fold, and a pan matrix naming channels that do not exist. Each is an input contributing nothing while still counting in a divisor, and none is visible in anything but a level. THE LEADING CHUNK IS THE TAIL OF THE FULL-LENGTH ONE. The Decoder settled by byte-span analysis that it is the movie's own dialogue, 17 of 17 -- killing its own hypothesis that it was an in-mission line -- and asked whether dropping it is a truncation, having no XMA1 decoder. Sliding envelope correlation with overhang allowed and normalised over the overlap: ADV r=0.998 at +52.8 s, S00A r=0.932 at +25.6 s, against controls of 1.000 (self) and 0.289 (a different movie). Both lags put chunk 0 flush against the END of chunk 1. Sample domain, lag refined to one sample then a scalar best-fit: residuals 16.70 dB and 23.15 dB below target. So dropping it removes a DUPLICATE and the exporter was right for a worse reason than it gave. The manifest note is NOT rewritten to claim that -- the structural conclusion belongs on the Decoder's page, not in my manifest -- but it no longer equates the chunk with BGM_103's third sub-wave, which a disc-wide census showed is a different structure, and it now says in words that the omission must not be read as junk removal. Not converted, deliberately: the Decoder's 504464 B anchor constant. Bytes per second is not constant even inside one region -- chunk 1 is 1118268 B and chunk 2 is 1171516 B for the SAME 137.324 s -- so any figure in seconds off it would be invented.

port: withdraw my own "two stems" reading of a voice region, and stop summing silence
The Decoder asked me to decode a voice region's leading chunk -- it has no XMA1
decoder in its container -- and the decoder run refuted a claim of mine that it
had already adopted into `docs/re/structures/voice-region-leading-chunk.md`.
I wrote that a region's two equal-length chunks are HANDOFF Q10's decoded
two-stem shape. Equal duration was a SHAPE match and I carried the music census
across on the strength of it. The content does not support it:
S00A chunk 2 is DIGITAL SILENCE -- 4497300 samples, peak -inf.
ADV chunk 2 is 0.60x chunk 1, best-fit scalar, residual 26.8 dB below the
target: about 95% of its energy is a -4.4 dB copy of the first chunk.
That cost real level. Summing chunk 1 with silence at 1/n put S00A's dialogue
6.02 dB down for nothing -- the exported file peaked at -16.2 dBFS against a
source chunk peaking at -4.2. `export_voice` now drops a digitally silent chunk
before the sum, which is arithmetic and not a judgement about content.
WHAT ADV'S NEAR-DUPLICATE SECOND CHUNK IS REMAINS OPEN AND IT IS STILL SUMMED.
Whether the game plays both is a decoding question, 26.8 dB of residual is not
nothing, and dropping a chunk because it correlates with another would be
answering it.
The leading chunk, answered as far as a measurement goes: ADV region + 1392, 394
packets, 84.553 s, stereo 48 kHz, peak -2.48 dBFS, 6 silent gaps over 0.4 s
totalling 45.3 s -- 54% silence, the same duty cycle as the full-length chunks.
Speech-structured, so not a header and not padding. "Cutscene or mission" is an
identification and this agent has no ears and no oracle; envelope correlation
peaks at 0.768 at the last lag in the search range, which is where a statistic
lands when it has found nothing, and it is not an answer.
Not taken yet, and said so in BLOCKED: the discriminator should be
`bank_header_len`, not a duration tie. This exporter never used `riffs.len()`, so
it already handles both of the Decoder's cases, but a tie is an observation and
`bank_header_len` is decoded. It switches when `c1f3608` reaches `main`;
`sylpheed-formats` is a path dependency and merging another agent's topic branch
is not the port's to do.

port: the voice is in the mix, proved by a null control that needed no test code
Three things verified against the re-export, none of them by reading the source. THE STEM READING IS CORROBORATED BY A NUMBER IT WAS NOT FITTED TO. Chunks are selected as "the longest, and everything tying with it" -- the movie's own length is not an input to that rule. The result now matches the picture to -0.114 s (ADV) and -0.085 s (S00A), where the concatenated version was +221 s and +161 s. THE VOICE REACHES THE MASTER BUS. `+ voice ADV` in the log proves only that a stream was found and played. The control is MODDING rule 4: 140 s of silence at data/mods/audio/voice/ADV.ogg shadows the exported file and changes nothing else, so no test-only flag was added to the runtime. The muted run reproduces the movie's own bed to 0.01 dB peak and 0.19 dB RMS; the unmuted run measures -22.913 dBFS RMS against -23.184 predicted for two incoherent sources at -24.941 and -27.965. 0.27 dB out. (A) SKIPS THE INTRO IN THIS BUILD. `--skip-at=25` ends the movie at 25.02 s through `Input.parse_input_event` and `_unhandled_input`, so the press-to-skip wiring is live and the play-test's report is not that bug. Untested here: a real key from a focused window. Unsettled anywhere: whether the GAME permits skipping an attract movie -- Q9, still amber, and if the answer is no this path is deleted rather than debugged. `check` accepts the new `voice` kind and holds it to the strict peak bound, with `bgm`, because it is a sum this exporter produced rather than a wave off the disc. FORMAT.md says what a `voice` entry is, that it keys by MOVIE NAME rather than by a role, and that its `why` names every chunk dropped.

port: the intro had no dialogue because the voice is a separate asset, and I concatenated it wrongly first
A human play-test heard music under the boot intro and no voices. The obvious reading -- the 5.1 fold dropped the centre channel -- is wrong. `ADV.wmv` carries music and effects only; a cutscene's voice is a separate continuous XMA stream in `sound.pak`, bound to the movie by the manifest in `tables.pak`. Nothing was dropped. The exporter had never been asked for it, so every fidelity measurement in AUDIO-VERIFICATION.md would have come back clean. `audio::export_voice` resolves it with `media::resolve_movie_voice_region` and never by filename: `RT01A`'s voice lives inside `VOICE_ADV.slb`, so a name match is correct on exactly the two movies this port would have spot-checked. Decoded, not authored -- so it runs outside the `authored/audio.json` block. THE FIRST VERSION CONCATENATED THE REGION'S CHUNKS AND WAS WRONG. It produced 359 s of dialogue for a 137 s movie. Decoding and timing each chunk shows two of them equal to six decimals and each spanning the whole movie -- HANDOFF Q10's decoded two-stem shape on a second asset kind -- so they are summed at 1/n. The error was visible only because the first version recorded the decoded length against the movie's instead of clamping to it; the clamp `media`'s own doc comment invites, and which `sylpheed-viewer` applies, would have produced a file of exactly the right duration containing the wrong audio. The dropped leading chunk matches no duration in its region and is NOT closed here. It is the same signature as `BGM_103`'s third sub-wave, already open in BLOCKED.md, now corroborated on an independent asset kind. Raised with the Decoder; the manifest names every chunk dropped and its length. Also in this commit, and separable: * `--skip-at=SECONDS` -- `--script` structurally cannot press during a movie, because `_script_settled` waits while `_player != null`. That is why "does (A) skip the intro" had been read out of the source rather than measured. * MISSION section 6 pins a 5.1->stereo matrix and this exporter has shipped a different one since P4 -- the same weighting, 7.65 dB quieter -- and said so nowhere. Re-measured with the right instrument (float decode, whole file, count the samples that would clamp, not a peak reading): the pinned matrix puts ADV at +4.26 dBFS on 4406 samples, while S00A never clips. So the pin overloads one movie and the constant is over-broad for the other. NOT changed -- the level of a mix is what section 6 reserves to a human. The export now carries a warning with the numbers. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01N7FiFFFwbvG2uxdcEh8HyF |

port: file the keyframe-layout change and the loading-screen answer in BLOCKED
Neither is taken. The keyframe record layout (every pose timed, exit_ramp_units decodable) reaches me only when that branch lands on main -- sylpheed-formats is a path dependency and merging another agent's topic branch is not mine to do. The loading-screen names are answered but carry two of the RE agent's own amber flags plus the index-space problem I found, so no name is written yet. Recorded with what limits the risk: static composites are byte-identical across the keyframe change, so this iteration's verify-screen baseline is the control to re-run the day the pin lands.

port: implement MODDING rule 4, and withdraw a red flag that was my own bad measurement
MODDING.md calls base-and-overrides "a design constraint on the exporter today, not a milestone to add later". Nothing read `data/mods/` at all -- the directory has existed since the monorepo merge with a .gitkeep and no code path anywhere. Eight milestones shipped past it. ExportTree.resolve() now shadows by path, and every read goes through it: screens, sprites, cues, the music bed, movies. MenuAudio was reading tree.root directly and would otherwise have made audio the one asset kind a mod could not touch, for no reason a modder could have guessed. No manifest, no registration step -- the path IS the registration, which is the whole of the rule. One tree, not a stack: layering needs a load order and nobody has asked for one, so data/mods/README.md says that rather than inventing it. Every shadowed file is printed as it is read. The first version summarised in _ready, before any asset had been read, so it always said "nothing shadowed yet" -- a report structurally incapable of reporting anything, which is worse than none because it looks like an answer. data/mods/ was NOT gitignored, and that is a hole in a hard rule: a mod is usually an edited game asset, and this was the one directory a user is invited to put modified sprites in and git would have taken them. Now excluded except the README. Gate: a synthetic 203x43 magenta PNG (nothing disc-derived) at data/mods/sprites/title/main_menu/ptbtn01.png changes 8501 pixels in a bounding box of exactly 203x43 at the button's position, and `check` still passes. RAISED, NOT RESOLVED: MODDING.md says the tree is data/base/, PORT-MISSION.md §3 and the exporter and .gitignore say export/. Both are mission files and only the human changes a mission. REFUTATION on Q3's paint-order key: 2 of 16 screens did not match a stable sort by layer key -- but that was my test. pgloading_eff00.prm carries NO layer key (layer_source "none"): a primitive with no sprite header and no implied-name fallback. I sorted keyless first; the decoders put it last, which is right, since it is the full-screen black quad and HANDOFF's own sentence is that the fade quad paints last. Completing the rule to "keyless last" gives 16 of 16. SURVIVES. Recorded because the published claim does not say where a keyless element goes and there is one in the archive. Separately the tie-break's reach looks understated: 105 elements share a layer key across 12 of 16 screens, where HANDOFF characterises the cost as "one element's blend on one screen". WITHDRAWN, and it was mine: I filed "the runtime mix has no headroom" in red twice, off a peak reading. Measured properly it is 43 samples at full scale in 5.9 s and 24 in 98.5 s, longest run 0.25 ms -- the disc's own confirm cue on a transient, possibly only in the 16-bit save. Nothing changed, deliberately: attenuating would be an unmeasured level decision of the kind I refused for the loop point. A peak reading is not a clipping measurement.

port: say at the top of BLOCKED.md that it is the ask list, and that nobody reads it
The port's open asks have now been delivered by message three times and lost three times, because the decoder container was recreated each time and a message dies with it. The asks themselves were never lost -- they are in this file, with the HANDOFF sha each row came from -- but `docs/agents/decoder-loop.md`'s read list does not name this page, so a fresh decoder has no route to it. This does not fix that. It makes the page introduce itself, so that ONE pointer at it is enough for a session that has never seen it, and states the gap plainly where both agents and the human will read it. Changing the loop brief is the human's call and I have not touched it.

decoder: tell it about the reference assets, and that the DB can be wrong
Some checks failed
The mounts landed but the agent could not learn of them: I documented them in CONTAINER-NOTES.md, which the decoder's prompt does not list, and then restarted the container -- so a fresh session with no memory of the exchange had a 586 MB database and a decompressed image sitting unmentioned in its filesystem. Now in the PROMPT itself, not only in a document, because the prompt is the one thing a new session is guaranteed to read. CONTAINER-NOTES.md is also added to its reading list. And the caveat that matters more than the asset. The .pe is PRIMARY -- the bytes the console executed. The database is somebody's ANALYSIS of them, produced by a disassembler that had to guess, and it is wrong in the ways disassemblers are wrong: misdecoded mnemonics where data was read as code, function boundaries short or long or merged or split, coverage missing entirely for code reached only by indirect dispatch, and names that are derived rather than symbols. So a finding resting on a database row is not established until the bytes agree: read the same address out of the .pe and check. Where they disagree the image wins, and the disagreement is itself worth recording, because it tells the next reader which parts of the database to distrust. A fast index into 9.2 MB of machine code, not a source of truth. |

decoder: mount the disassembly DB and the flat VA image
Some checks failed
The decoder had neither, and reported the gap precisely: four scripts in this repo READ /work/xenia-rs/sylpheed.db and nothing produces it, so the whole static PPC route was consumers with the producer missing. Both exist on the host and are now mounted read-only: the 586 MB database (25 481 functions, 851 classes with RTTI, EH tables, imports, 1.8M indirect-dispatch candidates) and the decompressed image. The image is the more useful of the two. It is a FLAT VA DUMP -- file offset = VA - 0x82000000 -- so reading a known address needs no XEX decrypt, no LZX, and no booted emulator. The decoder had independently recovered the same bytes by dumping /dev/shm/xenia_memory_* and validating against the GamePart table, which is good work and a sound method, but it noted itself that needing a running emulator is a bad dependency for something the entire static corpus rests on. It does not need one. Also recorded that an earlier claim the .pe was STALE was tested and refuted, so nobody re-litigates it, and that instructions.raw is an INT rather than hex. Written down as reference material, explicitly NOT a deliverable: they are read-only, they come from outside the repository, and a fresh checkout elsewhere has neither. Reimplementing the producer belongs in sylpheed-formats, and until it exists every static finding rests on an artefact this project cannot rebuild. |

port: P7 -- the new-game intro plays, and the two screens it skips are named out loud
S00A has been exported since P4; what P7 needed was something to play it and a
defined place to land. Both are here, and the interesting part is the gap.
The real chain is NEW GAME -> DIFFICULTY -> SELECT DATA -> (A) on a save slot ->
~4.5 s -> S00A. DIFFICULTY and SELECT DATA are MEASURED destinations that are not
GP_TITLE builds, so no screen file exists to go to. The port jumps from NEW GAME
to the one thing in that chain it has -- and the whole design is about not
letting that read as a sequence:
* MenuFlow.accept returns a new kind, `video`, rather than folding this into
`blocked`, because the caller has to announce the skip and a distinct kind is
what forces it to;
* the runtime prints the skipped screens by name on every run;
* flow.json carries `skipped_chain` as DATA, so what is missing lives beside
the decision instead of inside a GDScript string.
After the movie the port returns to the title. Authored, and it has to be: the
game goes into mission 1 and gameplay is out of scope. The ~4.5 s before the
movie is left EMPTY on purpose -- GP_TITLE does carry a loading screen and 4.5 s
is about the right shape for one, which is exactly why that belongs in BLOCKED.md
and not in flow.json.
`--script`'s 20 s per-step timeout would have killed every movie run at step 1.
Raising the constant would have been wrong the other way: a movie stuck at frame
0 would then hang the job, and a job that waits is worse than one that fails. The
test is now LIVENESS -- while get_stream_position() advances the deadline moves
with it, and a stalled movie still trips the same 20 s.
Found while looking: GP_TITLE's four unnamed builds (entries 0, 1, 12, 15) are
LOADING screens -- every element in all four is pgloading_*, and LOADING is one of
the three names the decoder read out of the title part's state function. NOT
renamed here: which member of each pair is which locale is an inference, and a
name stops being questioned once written. Handed over.
One of them is a second casualty of the rest.t problem, and a worse one:
pgloading_eff00.prm rests OPAQUE BLACK at t=38, so anything drawing that screen
at its declared rest paints a black rectangle over all of it. The title's case
only dimmed a frame.
REFUTATION, attempted and SURVIVED: HANDOFF says "exactly the six screen builds
carry the black .prm quad while the six overlays do not". Counting bundles with a
full-screen black primitive gives 8 and 4 -- build_12/15 carry one too. But
theirs runs black -> held -> clear where the transition quad runs black -> clear
-> black, so read strictly as "the quad whose group is the transition" the claim
holds. Recorded anyway: there are two kinds, and the naive census over-counts.
Gate: NEW GAME -> S00A plays 93.75 s against a declared 93.9 -> title, with
98.453 s recorded off the Master bus. What that does NOT show is that S00A's own
audio is in the mix -- bed and movie were not separated in this run, and the
write-up says so.

port: end the boot when BOTH builds have arrived, not when the plate lands
Moving the plate onto the shared clock moved the boot's exit with it: the run quit at the overlay's settle (t=238) while build 4's own fade-in from black runs to t=261. pteff00 is still ~7 % opaque there, so the capture came out visibly darker than the previous one -- with nothing failing, no warning, and no line in the log to say why. Caught only because there was an earlier capture beside it. The boot now ends at max(view.settle_time(), overlay.settle_time()) and prints the unit it is waiting for.

port: the ring spins, the plate needs no constant, and rest.t was never the settle
Two milestones' known-wrong bits, both now answered by the RE agent, both taken. P5 -- the focus ring. It was drawn at 0 with a comment saying so. The period is now measured (continuous spin, eight evenly spaced autocorrelation peaks over nine revolutions, no angle estimated anywhere) and it needs NO authored constant: the period is the element's own declared t=120, and what the measurement adds is only that the turn repeats rather than stopping -- which "groups hold" could not decide, because 0 and 360 are the same pose. `spin_period_units` is structural and narrow on purpose: two keyframes, differing in nothing but rotation_deg, by a full 360, first timed and second untimed. 16 of 212 elements in this export match and all 16 are focus rings, zero false positives. That check is the point -- the measurement was taken on ONE button of ONE screen, and a rule that caught anything else would be extrapolating it to elements nobody watched. Verified on the port's own render with the RE agent's own control: bit-identical one period apart across the whole frame, 3.6/255 inside the ring's box at quarter-period steps, and box luminance conserved to 0.027 % over eight phases -- which is the observable they used to separate rotation from a pulse. Not claimed: direction (no signed angle was ever measured) and phase across a focus change (their run held focus throughout). P3 -- the plate. Last iteration I refuted their authoring instruction and shipped it anyway rather than pick between two of their numbers. The refutation held and the answer came back better than either option I offered: AUTHOR NOTHING. Both builds run on one clock started together and the plate arrives at its own declared t=238. The 2.13 s constant is deleted. The premise that failed was mine: rest.t IS NOT WHEN A SCREEN SETTLES. It is the last hold keyframe before the exit. ptlogo1 stops MOVING at t=42 and then creeps 5 px and 31 alpha steps to t=251. Reading rest.t put build 4's arrival at 4.350 s instead of 1.967 s, and the "2.51 s, which is not a landmark of anything" I sent them is that error wearing a decimal point. 238 - 118 = 120 units = 2.000 s against a measured 2.135 s at 28.1 fps presentation. Checked against my own export before touching anything. `ScreenView.settle_time()` still uses rest.t, and so the boot sequencer paces every screen off the wrong landmark. NOT changed here: "visible arrival" is a heuristic and getting it wrong re-paces everything. Filed, and asked for a timed boot instead now that their oracle is live. REFUTATION: two of their pages measure the same declared 120 units of wall clock during a static hold and disagree by 2 % -- plate 2.135 s (28.10 fps implied), ring 2.177 s (27.56 fps). That is seven times the plate page's own 6 ms run-to-run agreement, and it lands on the argument that page uses to justify itself: "the build-in is where frames are dropped; the static hold is not". Also the ring page's band, 27.6-28.8 fps, does not contain its own measurement -- the mean needs 27.56 and four of seven spacings are outside. Filed, not worked around: my port uses the declared 120 units either way.

port: P3 -- the boot title gets its PRESS (A) plate, and two of the RE agent's numbers do not agree
ScreenView now draws two builds at once, which it never had to before. It is a second ScreenView in the same SubViewport rather than a subordinate screen inside one: each build has its own timeline, its own textures and its own hold, which is the entire content of the finding, and Node2D siblings already paint in tree order. `paint_order` still means what it meant -- an ordering WITHIN a build. The delay is authored in flow.json on the BOOT STEP, not on the `title` screen. What was measured is the boot title; whether the plate is there when the title is reached again -- (B) from the menu, or after the attract movie -- is not, and hanging it on the screen would quietly claim that it is. REFUTATION, and it is the substance of this commit: the RE agent's authoring instruction does not reproduce the RE agent's own measurement, and the gap is 3.97 s. The instruction is "when build 4 has settled, wait 2.13 s, composite build 2". But build 2 has a group and this port plays groups -- ptbtn00 is alpha 0x00 at t=214, still 0x00 at t=236 while it slides 10 px up, and 0xff only at t=238, which is 3.967 s at 60 units/s. So the plate is first VISIBLE at settle+6.10 s, while what was measured -- the glyph counter leaving 154 -- is visibility at settle+2.13 s. Both groups starting together puts it 0.38 s BEFORE settle; build 2 starting at settle puts it at settle+3.97 s; landing on the measurement needs build 2's group to start 2.51 s after build 4's, which is not a landmark of anything. The measurement is untouched -- it is an observation of the running game and I have no standing to doubt it. What is refuted is the step that turns it into an authoring rule. So the port ships the instruction, prints the discrepancy on every boot, and files the row. Same call as the BGM sub-waves: a port that quietly picks the number that looks right destroys the evidence, because a corrected boot looks exactly like a correct one. Also refuted, and it was mine: BLOCKED.md has said since P2 that "no element's alpha reverses direction anywhere in this export, so nothing pulses". ptbtn00 reverses -- 0x00 -> 0xff -> 0x00 -- and it was in the export the whole time. The claim had been checked against the screens P2 happened to be animating. The port still draws no pulse, because no reading of this group yields the measured 2.24 s: the whole group is 4.47 s and from its first keyframe 0.90 s. Gate: `--boot --capture=` writes one frame of the composited end state, instead of the 600-PNG filmstrip that was previously the only boot artifact. `--screen=title --overlay=press_start` raises the same composite in two seconds for anyone who does not want to sit through 137 s of Theora.

port: P6 -- the menu has sound, and the BGM I "chose" was decoded all along
The three Static.slb cues and the menu bed now export to Ogg Vorbis and play.
`sylpheed_formats::media` does the assembly; nothing in port/ has heard of XMA.
Three things this milestone got wrong before it got right, all recorded in
docs/port/DECISIONS.md because the corrections are the useful part:
1. The cue offsets were a Rust `const` in the exporter. They are MEASURED, not
decoded -- a measured value compiled into the exporter is a measurement
wearing the costume of a decoded field, and nobody deletes it because nobody
can see it. They are authored/audio.json now.
2. I picked BGM_001 and wrote a careful `why` calling the choice arbitrary. The
menu's music is BGM_103, and it is in HANDOFF at

agents: merge main at the start of every iteration
Some checks failed
Both agents read the protocol, their mission and the shared tooling from their OWN checkout, and both work on topic branches -- so without an explicit sync they follow whichever version of the rules existed when the branch started. Found concretely: tools/audio-capture and two protocol revisions were on main while the decoder worked for hours from a branch that had neither. The port had merged on its own initiative and did have them, which is exactly the kind of divergence nobody notices until the two disagree about what the rules say. |
