port: make ScreenView say what it could not draw; refute 'first-declared paints first'
skipped[] has been tracked and read by nobody since P1, under a comment saying a silently missing element looks like art. _note_structural prints from inside ScreenView rather than returning a value for a caller -- routing it through a caller is exactly what did not happen. Structural skips only; transparent-at- rest is ordinary animation. Zero found today: a guard, not a fix. The first version of that scan was a FALSE PASS: screen_view.gd did not parse (a line inserted at three tabs inside a four-tab block -- the substring assert matched a shallower indent), so grep counted zero from a dead script. The scan now counts the summary line as a positive control. Refutes 'the first-declared element paints first', which would have made the forced-backdrop rule redundant since all six forced elements are index 0. False on 8 of 16 screens -- decisively on main_menu, where index 0 is pteff00, painted LAST, and pteff00 is a measured control.

port: P7 gate verified end to end, and a defect I nearly invented from a masked correlation
NEW GAME opens S00A, plays 93.33 s against the manifest's 93.9, returns to title. Nine film frames distinct and non-black. Nearly filed 'the movie's audio never reaches the bus' from r=-0.0068 at the movie's known start, with the correlator passing its own control at r=1.0000. False: re-run bed-free on the boot path, movie audio r=0.418 and voice r=0.886 at the same start. The menu bed masked the quieter movie below detection. The lesson is the control: I validated the instrument on clean data and ran it on masked data. A negative needs a positive control under the SAME masking. Third unvalidated negative in this corpus to nearly become a finding. Also confirms the Decoder's unresolvable-element hazard does not reach GP_TITLE: 115 .t32, 45 .rat, 18 .prm, no .tbm, every non-primitive resolvable.

port: test backdrop coverage per instant -- scale animates, and the disc proves it
The Decoder found forced_backdrop judged coverage from declared size alone. pbafc.prm declares 844x600 at alpha ff and draws ~17x18 px at 2%x3% scale -- a rule reading declared size would call it screen-covering. scale_at interpolates on the same ramp as the fade, and coverage is folded into the opaque-instant test: an instant counts only where the element is BOTH alpha 255 and covering. The previous code tested the two halves at different times. The size prefilter deliberately no longer rejects, since an element scaled above 100 could cover from a smaller declared size. No verdict moves: 6 forced before and after, 16 screens validate, oracle figures identical to the digit. Nothing in GP_TITLE has a non-100 scale on any keyframe. It is in because the data that would break it exists, not because it failed.

port: P6 gate verified with sound on the bus; tighten the backdrop guard to a positive primitive test
verify-menu-audio records the Master bus over the P5 walk under the Dummy driver. A dead press is bit-identical to the bed alone; all three cues match their exported wave in the recording with margin over a bed-only control; the cue order matches the script order, which the correlator was never told. The first version of this tool counted envelope bursts above a multiple of the bed and gave 4 cues on one run and 0 on the next from the same script. Replaced with template matching, which has no tuned constant. Cue LENGTH is deliberately not asserted -- the bed masks the tail and I nearly filed that as a defect. Also acts on the Decoder's .tbm self-refutation. No port verdict is affected -- all six forced elements are .prm solid black, and GP_TITLE has no full-screen .tbm at all -- but the guard was sprite.is_none(), a symptom test of the same shape as the one they say fixed their symptom not their cause. Now role == primitive. Six verdicts identical, 16 screens validate.

port: audit what rests on a single draw-stream run; black_hold_units=9 sits at the top of its range
Their ARM=early disclosure (~40% silent trigger loss) makes every draw-stream figure n=1. Exactly one port constant depends on one: the black hold. Three of its supports have moved -- the 105-frame count they revised to 114, the 2.231 corroboration they retracted, and a run-average rate now known to drift 33%. Redone on their corrected segments the two runs give 8.95 and 6.71 units, not one number: overlapping +/-1 error bars are not agreeing central values when one frame is a third of the quantity. Range ~6.5-9.2, port at the top. Value UNCHANGED and proposed rather than adopted -- it would be my arithmetic on their instrument. Filed with the single run that would settle it. Also checks their statistics: per-boot excesses reproduce exactly, and their 2.3 sigma uses population SD where sample SD gives 1.89 -- cutting against their own concession. Neither framing reaches significance. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01N7FiFFFwbvG2uxdcEh8HyF |

port: their corrected calibration matches the file at all six points; guard the 60 against emulator drift
Counting indices/4 lands every transition where the export's declared alpha>0 count changes, within a half-open boundary. Their quad counts (1/2 publisher, 3/6 developer) also reproduce exactly when restricted to sprite-bearing elements -- independently confirming the layerless backdrop is absent from the batch they log. Refutation: their drift explains the corpus 4.1% in SIGN but overshoots in magnitude 2.4x (predicts a 1.369 ratio, corpus shows 1.278, declared 1.214). The drift was measured in their container and the 4.1% belongs to a different instrument -- the same transfer I just got wrong with build 4. Guards keyframe_units_per_second at the constant itself: 60 is the game's logical rate, not a frame rate, and the 33% drift is not evidence about it.

port: withdraw 'the boot is known too fast' -- the splash dwells are declared and the port already played them
The Decoder measured both splashes over 3 cold boots: publisher t=0..255, developer t=0..210, the developer agreeing with wall clock to 1.1%. The port emits each declared value plus the 9-unit black hold, exactly. No code change. My error was the generalisation, not the arithmetic: build 4 is the title, whose exit is caused from outside its timeline, so it holds; a splash's exit is caused by nothing, so it plays out. I used the one boot screen the port is unaffected by to overturn the two it governs. Declining to scale by 9x while adopting the conclusion that implied was half a caution. Also refutes their two splash boundaries as not comparably anchored: 2.237 vs 2.414 units/frame in one boot, and the publisher has a glow symmetric with the developer's three.

port: the clock freezes at settle -- my window is the game's, and the boot is known too fast
The Decoder measured build 4's top-level clock stopping inside [160,236]. The exporter computes title's settle window as [160,236,198] from the file alone. Same interval, two independent methods -- the first evidence for the settle instant that does not come from our own renderer. ptcopyright reaching alpha 255 exactly at t=160 agrees from a third direction. Corrects a claim in three places: timing.json, flow.json and boot.gd all said a screen's dwell IS its keyframe group and the port reproduced 'the disc's own pacing'. Build 4 declares ~120 presented frames and dwelled ~1100. The decision to hold zero extra stands; the claim that it was faithful does not. Checks their two declared spans against the file: both exact, with a 106-vs-105 interval-convention quibble that changes nothing.

port: close the span row -- 256 and 211 are both ours, on different splashes
The Decoder resolved it: palogo_eff0.prm is on BOTH splash pairs, publisher running to t=255 (256 instants) and developer to t=210 (211). My own census table had both numbers side by side and said the offset was not constant; I filed a disagreement anyway by comparing one of my numbers to one of theirs. Span convention confirmed as implemented. Records their counterfactual: the hold decides 55% of verdicts disc-wide, and palogo_eff0's measured order rules out the reading I nearly shipped. Boot gate re-run after the reorder and still holds. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01N7FiFFFwbvG2uxdcEh8HyF |

port: census every layerless full-screen element; the forced-backdrop quantifier misses nothing in GP_TITLE
Tries to refute the rule by SUFFICIENCY rather than correctness: a strict 'all others visible' quantifier fails quietly, so the question is whether any full-screen opaque backdrop misses the bar and keeps hiding its screen. None does. Everything that fires is at 100% of others; everything that does not is at 13-47%, and pteff02 never reaches alpha 255 at all. No borderline case. Reproduces the Decoder's second control exactly (pteff00 forced below 3 of 23) and shows their palogo_eff0 span gap is not a constant offset -- 211 is the number our developer_logos row does reproduce. Also retires the 'loading screen fade quad rests OPAQUE BLACK' row: resolved by the rule, and it recorded rest.t as 38 where it is 0.

port: implement the Decoder's forced-backdrop rule; two screens were black for their whole life
build_12 and build_15 rendered mean 0 at every instant of a PLAYING timeline, and verify-screen scored both OK -- two renderers sharing implied_layer_key, comparing nothing against nothing. Implements the constraint as a post-pass over ui_layout::derived_paint_order, with both of the Decoder's limits copied verbatim: layerless elements only (a sprite's element alpha says nothing about its texture's coverage) and NOT a name heuristic (palogo_eff0 is named like an overlay and paints first). Both controls reproduce: palogo_eff0 forced first, pteff00 still last on all four title screens at exactly 2 opaque instants. Splashes unmoved against the oracle at 0.01%.

port: the loading screens are black at EVERY instant, which disproves my layer rule
build_12 and build_15 have rendered blank since P3 and I had filed it as a rest() casualty. It is not, and the corrected keyframe association makes it provable. pgloading_eff00, a 1280x720 black quad, is opaque alpha 255 from t=0 to t=38 and clears at t=48. Every other element on the screen peaks between t=8 and t=32 and is gone by t=32-40. So the quad covers the entire span in which any content is up, and clears only after everything else has faded. Rendered with the timeline PLAYING at t = 20, 30, 36, 40, 42, 44, 46 and 50 units, the frame is mean 0 at every one. That is not a bad choice of pose. Under the port's current layer rule there is no instant at which this screen shows anything, and a loading screen that is black for its whole life is not what the game does -- a proof by contradiction rather than a preference. THE RULE UNDER SUSPICION IS MINE AND IT IS NARROW. pgloading_eff00 carries layer_source "none" and the exporter sorts a layerless element LAST, on top. Every other full-frame primitive in the export has a layer key (main_menu, extras and title all give pteff00 0x00008030), so this only ever bites here -- which is why it survived eight milestones behind two screens nobody draws. Where a layerless element sorts is a DECODE and I have not answered it. If the game sorts it first, behind everything, the screen renders and the quad becomes a backdrop, which is consistent with the contradiction but not established. Asked rather than flipped. It does settle that verify-screen's BLANK verdict on those rows was right: sylpheed-cli agrees with the port there precisely because it shares the assumption under suspicion. Also recorded: the Decoder has withdrawn "the game never draws eff3" -- it draws all five -- and the mechanism is the one my developer-splash refutation caught a layer down. A draw batches several quads and the log dumps only the first 8 vertices, so min/max merges them; eff3 lies entirely inside eff4 so the union is exactly eff4's extent. My 525x259 was gamearts_eff merged with seta_eff the same way. Nothing in the port changes: eff3 was never dropped and the splash still draws three sprites.

port: the menus' residual is the tone floor, and extras is not really 3x worse
extras sits at 0.19% differing against main_menu's 0.06%, on two screens of the same family. The signed difference explains it: both are uniformly +9 to +12 brighter in the dark outer columns, in nearly identical patterns (+12.13/+12.29 against +11.63/+11.03 at x=0; +10.60/+9.05 against +10.24/+8.84 at x=960). That is the transfer curve -- gamma > 1 in the darks -- with no dipole, no displacement and no missing element. So the 0.06/0.19 gap is not a difference in fidelity. The thresholded count only sees pixels differing by more than 64 levels, which are text and sprite EDGES, and the two screens have different amounts of high-contrast edge. The level disagreement, which is what a tone term produces, is the same on both. I had taken the ratio of two counts as meaningful -- the bounding-box lesson in a different costume. A DIAGNOSTIC TRAP OF MY OWN: the first pass reported 10 of 18 elements "transparent at rest" on extras -- the buttons, the title, the frames -- and looked exactly like a missing-element bug. `--screen=NAME` without `--time` renders at t=0, and pose_at clamps t to minf(t, settle_units), so t=0 stays t=0. With --time=2.0 it draws 18 of 18. The tool was right and my invocation was wrong, and it reported a WORSE problem than existed, which wastes an iteration rather than hiding one. REFUTATION ATTEMPT, SURVIVED: the Decoder's 239.8 units for palogo_sqex's alpha >= 1 span, which is the denominator of the units-per-frame conversion behind the 9-unit black hold I just authored. Computed independently from my export under the linear ramp the port already uses: alpha first reaches 1 at t=15.0588 and last exceeds it at t=254.8750, giving 239.816 units. Agrees to four significant figures, from different sides of the same record -- which is what makes that constant safe to hold.

port: the title's sweeps loop, the black hold is 9 units, and one claim refuted
THREE THINGS FROM THE DECODER, one of which I am not taking. REFUTED: "the developer splash is one composited quad, the bounding box of the three logos". The observed quad is 525x259 at (378,155). The three logos' bounding box is 500x421 at (390,164) -- a 259-tall quad CANNOT contain them, and palogo_anima alone starts at y=449, thirty-five pixels below that quad's bottom edge. The observed quad matches the union of gamearts_eff and seta_eff, 521x261 at (379,154), to about four pixels in every dimension -- and both of those are TRANSIENTS my own census flagged, dark by t=45, so a frame containing that quad is a build-in frame rather than the settled screen. I cannot see their draw stream, so I sent the arithmetic rather than a verdict, and the port keeps drawing three: I will not stop drawing an element on a claim whose stated identification excludes that element from its own bounding box. THE BLACK HOLD IS 9 UNITS, NOT 12. I authored 12 from Q7's luminance plateau of 0.17-0.23 s, supported by the menus' transition quad. The Decoder counted SUBMITTED QUADS instead -- luminance cannot separate the outgoing fade's tail from true black. Four frames with no sprite quad at all, at 2.284 units/frame derived from the disc as its own clock, gives 9.1 units = 0.152 s (6.9-11.4). That overlaps the luminance figure only at the top, and the true black is SHORTER still since both boundary frames carry picture. My 12 was supported by analogy -- a different screen's quad on a different path -- and a number that fits by analogy loses to one measured in place. verify-dwell's bound moved with it; both screens still agree. THE TITLE'S SWEEPS LOOP. The oracle shows the quad oscillating over its whole x range and resetting hard, one reset in the first title dwell and two in the second. The loop-length field could NOT have settled it, correcting a hope I had stated: both records declare exactly their last keyframe time, slack zero, and "loops at 600" and "runs once for 600 and stops" write the identical header. Verified on the two sweeps' LCM, since their periods differ: 600 and 720 realign at 3600 units, mean diff 0, against 0.438 at half that. Scoped to the title. The menus declare the same lengths but the oracle measurement is of the title, and my own weak evidence points the other way there -- best match with the sweeps off-screen, three times worse mid-screen, against a 73% on-screen duty cycle if they looped. Two weak signals in opposite directions is a reason to scope, not to pick.

port: refute my own "the menu residual is the sweeps", and show the narrow windows are harmless
TWO RESULTS, both correcting things I had written. THE NARROW SETTLE WINDOWS ARE NOT A GAP. Adopting the settle instant left main_menu and extras on per-element rest() -- windows of 12 units, below the 30-unit bar -- and I recorded that as something left behind. rest() is malformed only for a TRANSIENT, and the transients are precisely on the screens whose windows are wide: title (76) has ten, publisher_logo (190) and developer_logos (145) have one and three, and main_menu and extras have NONE. The discriminator is returning to dark far before the screen's own end -- ptlogo_back2eff1 is dark again at t=58 while the title runs to t=269 -- as against the ordinary fade-in-hold-fade-out every menu element has, where rest at 255 IS the settled pose. Not claimed as a rule: two screens having narrow windows and no transients could be coincidence, and n=2 is where I have gone wrong before. REFUTED, MINE: "the menu residual is localised on the ptloop sweeps", which I have written twice. It came from reading the BOUNDING BOX, which sat at (441,230) -- the sweep position. Sweeping the leaf's phase against the live-menu capture: 0.063% at t=60, 0.183% mid-screen at t=350, 0.061% parked at t>=600. With them parked the box is 834x358 at (445,167) -- the button column, where the focus signature lives. On extras the same test moves the box (398x295 at the sweep position, then 736x525 spread) while the magnitude barely changes, 0.192% against 0.200%. So the box moves with the sweeps and the residual does not. A bounding box over scattered pixels tells you where the outermost differing pixels are, not where the difference is -- and I had been quoting it as if it localised a cause. verify-capture prints that box, so this is a caution about reading my own tool. And a first piece of evidence on whether the sweeps loop: the disc gives one pass ending parked off-screen, ORACLE-CAPTURES says they "move continuously" which I had read as implying a loop, and the idle menu capture matches best with them OFF-SCREEN. One capture and a weak instrument for an absence, but it is the first evidence either way and it points against looping.

port: the publisher residual was a missing black hold -- we had both dismissed it
I carried this as "0.03 s outside a composite bound, probably a property of the bound rather than the game", and the Decoder agreed. Both wrong, and the way it was settled is the point: I stopped reasoning about the bound and filmed the transition. At 0.05 s the port fell straight out of the publisher's fade into the developer logos -- mean 5.06 -> 0.32 at t=4.20, then 5.65 at t=4.25. NO BLACK FRAME AT ALL, where the oracle measures a 0.17-0.23 s pure-black plateau (HANDOFF Q7). The bound was fine; the port was missing a fifth of a second of black, and had been since P3. Authored at 12 units because the boot path has nothing to read it from: publisher_logo and developer_logos each carry a single palogo_eff0, a 1280x720 primitive with ONE keyframe at t=0 -- static, not a transition ramp. The menus' quad declares black for 12 units and 12/60 = 0.200 s sits mid-range, so the number is the disc's where a screen has one. Filmed after: t=4.25, 4.30, 4.35, 4.40 all at mean 0, then the developer logos at 4.45. publisher interval 4.26 DIFFERS -> 4.47 agrees; developer 3.62 -> 3.73, still agrees. Settled-frame comparisons untouched, as they should be. THE LESSON IS THE SHAPE OF THE DISMISSAL, NOT THE NUMBER. "A 0.03 s miss against a bound composed from two measured ranges plus jitter slack is more likely a property of the bound" is plausible, was accepted by both of us, and was wrong. The composite bound is why the miss looked small -- the underlying gap was 0.2 s -- and a plausible explanation for a small number is how a real defect stays hidden. The film cost one command. Also recorded: the Decoder has reproduced across two build-ins that the console NEVER draws ptlogo_back2eff3 (0 draws against ~5 expected), with sampling phase, invisible draws and position error all ruled out -- but WHY is not established, and nothing in eff3's record differs from its neighbours. The port keeps drawing it, deliberately: dropping an element the disc declares on a measurement with no mechanism is authoring a behaviour neither agent can derive, and nothing this port gates on would notice, since the flashes live only in the build-in and verify-capture compares the settled frame.

port: their "do not draw all five flashes" flag, checked -- the port already staggers them
The Decoder caught the title's build-in on the console and found ptlogo_back2eff3 never drawn -- not a miss, but phase: a flash's peak is 2 keyframe units, 0.85 of a presented frame at that pacing, so the console shows a SUBSET on any given play. The warning was that drawing all five would read heavier than the real thing. Checked rather than reasoned about. Sweeping the build-in with --no-hold, the port draws them sequentially -- eff1 at t54-56, eff2 at 58-60, eff3 at 60-62, eff4 at 62-64, eff5 at 64-68 -- never more than two at once, and those only where their declared windows abut. That is the stagger the disc declares. The pile-up was the rest() bug and it is fixed. SO THE DIFFERENCE FROM THE CONSOLE IS PRESENTATION RATE, NOT CONTENT. At 60 fps each 2-unit flash gets ~2 frames; at the console's pacing it gets 0.85, so some are skipped. A frame-by-frame comparison of the build-in against a console capture will show flashes the console missed -- a fact to know rather than a bug to fix. The settled comparison verify-capture makes is unaffected: at t=198 none of the five is drawn. Also recorded: my top-level restriction on the settle window was verified by them rather than merely accepted ([160,236] width 76 against [269,540] width 271 with the leaves in, which is an instant after every top-level element has exited); the 120-unit loop is confirmed from the guest's own vertex colour alpha, observed range 0..80 against a decoded peak of 80, with the decoded ramp fitting at RMS 13.16 against 38.18 reversed; and a trap for any future draw-stream tooling here -- a 2D draw's identity is its vertex geometry, not its bound texture, because these sprites sample large shared pages.

port: pose a settled screen at ONE instant -- title 1.81% -> 0.26%, splashes to 0.01%
The Decoder's finding, applied. `rest()` returns each element's last hold keyframe chosen independently of every other element: right for anything that ends the screen settled, exactly wrong for a transient. The title's ptlogo_back2eff1 is a two-frame flash (0 until t52, 255 at t54-56, 0 by t58), so its last hold IS the flash peak and rest() left it burning -- five of them, drawn at once. The settled instant is the longest interval containing no keyframe time, over a bundle's TOP-LEVEL elements. Reproduced here before adopting: title [160, 236], midpoint 198, the Decoder's number to the unit. The top-level restriction is what makes it match -- including the ptloop leaves gives [269, 540]. AGAINST THE ORACLE: title 20.92 RMSE 1.81% -> 14.61 RMSE 0.26% publisher_logo 9.05 0.75% -> 2.17 0.01% developer_logos 8.86 0.33% -> 3.05 0.01% main_menu 0.08% -> 0.08% window too narrow extras 0.19% -> 0.19% window too narrow Seven times fewer differing pixels on the title, seventy-five times fewer on the publisher splash, whose differing region is now a 13x18 box. The largest correctness gain this port has had, and none of it is mine -- it is a decode computed from the keyframe table with no reference to any capture. APPLIED ONLY WHERE THE WINDOW IS WIDE, and the bar is not invented. This export's widths split with nothing in between: 214, 190, 145, 76, then 12, 12, 8, 4. The bar is 30 units -- the Decoder's disc-wide census puts the knee there (30% of bundles >= 30, 42% under 10, the latter mostly loop* fragments meant to be in motion) and this export's screens sit 4x either side with nothing between 12 and 46. Two independent populations agreeing on where to cut. Checked unbroken: boot pacing unmoved, scripted walk runs end to end with focus restored. Also recorded: my "34 focus-record elements, only 2 varying" is right for GP_TITLE and reads as a fact about the format -- disc-wide it is 210 varying, 202 with rest() at the peak, concentrated in the paks a wider port reaches next. And their sharper framing, which I have adopted: a pulsing element has no resting pose at all, so rest() is MALFORMED rather than mis-answered on one.

port: BLOCKED -- the paint-order tie-break costs zero pixels on every screen we ship
The old figure was 24 overlapping tied pairs, and it was a rest() count: 10 of the title's 11 tied pairs are between the five transient flashes, which are transparent on a settled screen. Measured at settle, the cost is ZERO on all five screens this port ships, and the only non-zero anywhere in GP_TITLE is 1 px at delta 1 on the Japanese title, which is out of scope. Sweeping every keyframe time and midpoint, the live-pair count is flat across the settle window, so it is not a knife-edge. Recorded with the Decoder's own caveat rather than smoothed: four loading bundles report zero with no live control, so those are a weaker zero than the other six. And why ties order as they do is still unknown -- it now costs one pixel.

port: the plate's period is 120, decoded -- and 105 was falsified with my own ring number
The Decoder found it in the format: a nested record is itself a RATC bundle and its header's +0x08 is the LOOP LENGTH. A record's keyframes need not fill it and the slack is a hold at the final pose, so ptbtn00f is 105 units of ramp inside a 120-unit cycle -- the glow rests dark for 15 units. The five ptbtn0Nf records fill their 120 exactly, which shows the slack belongs to that record and not to the format. Disc-wide over 1781 timed nested records: 92.3% declare exactly their last keyframe time, 7.7% more, 0 LESS -- the falsifier never fires. THE DECISIVE TEST USED THIS PORT'S NUMBER. Both candidates need the same emulator pacing factor, and the ring measures it independently: declared 120 -> 2.177 s -> 1.0885. 105 units needs 1.211-1.337 to reach the measured 2.12-2.34 s, which EXCLUDES it; 120 units needs 1.060-1.170, which CONTAINS it. Two different elements in different bundles, separate runs, tied only by both declaring 120. My three readings in order are the useful record: 129 (105 + the since-deleted exit_ramp_units) fitted the measurement for a reason that evaporated; 105 (the group length) I shipped knowing it was 17% short; 120 is decoded. And the 123-vs-129 pair I once called unseparable STRADDLED the right answer without containing it -- the sharpest argument I have seen against treating "two candidates, nothing separates them" as if the truth must be one of the two. Verified bit-identical 120 units apart (mean 0), 0.061 at a quarter, 0.888 at half. Still authored because the pinned tag does not expose +0x08; delete the entry the day a tag does. THEIR rest() FLAG, CHECKED RATHER THAN ASSUMED: they warned a focus record is the kind of element rest() mishandles. Censused -- 34 focus-record elements, only 2 with a varying alpha, both ptbtn00f, whose rest.alpha of 80 IS their peak, exactly the pathology described. The port does not hit it because the plate draws through the loop path, and the other 32 are constant-alpha so rest() is safe.

port: the focus ring had silently stopped, and the plate's period is now the disc's
BLOCKED said the record-layout change touches five things: pose_at, settle_units, spin_period_units, exit_ramp_units and the plate. I checked two, reported that, and did not work the rest of the list. `spin_period_units` required "the first timed and the second untimed". Under the corrected layout the ring reads t=0 rot=0 and t=120 rot=360 -- both timed -- so the rule returned 0 and THE FOCUS RING STOPPED SPINNING. Nothing reported it: a period of 0 is a legal "this element does not spin". Rewritten to take the SPAN between the two poses: 120 - 0 = 120 units, the same number the old rule produced, which is evidence the corrected layout is self-consistent rather than merely different. Verified the way P5 verified it, by bit-identity one period apart on the ring's own 60x60 box so the ptloop sweeps cannot confound it: 0 at +120 units (twice), 8.61 at a quarter period, 8.88 at half. Three wrong instruments on the way, and the sequence is the lesson. A whole-frame `max` saturates on one rotating edge (adjacent frames scored 131 with a mean of 0.022). A live --menu filmstrip jitters by up to a frame, which is ~3 degrees of ring. And a whole-frame comparison is dominated by the sweeps, which move 480 px over one ring period. `--focus=<id>` was added so a --screen run can draw a focus record deterministically, which is what made the check reproducible. THE PLATE'S PERIOD IS NOW 105, THE DISC'S OWN GROUP LENGTH, and it disagrees with the measurement. The ambiguity the entry carried is gone -- it used to say the cycle might restart at t=6 rather than 0 and that nothing separated them; the group now runs t=0 to t=105, both at alpha 0, and there is one reading. But 105 units is 1.750 s, or 1.906 s scaled by the factor the ring shows between its declared 120 and its measured 2.177 s -- about 17% below all four corpus timings (2.12 / 2.19 / 2.34 / 2.31). The old 129 gave 2.34 s, at the top of the range, which is why it looked right. 129 was the last timed keyframe plus exit_ramp_units, and that constant is deleted. A period built on a constant that no longer exists cannot stay even though it fitted better, so the port ships the disc's number and says it is wrong. Verified bit-identical 105 units apart, 0.83 at 30 units. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01N7FiFFFwbvG2uxdcEh8HyF |

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.
