re: an unchecked aside said a .prm is 'skipped as everywhere else' -- it is the black backdrop
sylpheed-port named the mechanism after copying an unchecked aside of mine into an authored file twice, inside the same why that carefully said their re-derivation does not name the screen. Scrutiny goes where the weight is, so a claim carrying no weight attracts none, and then it reads as measured. Swept this corpus for the shape and found one in the port's own domain. ui-composable-bundles.md said a .prm element 'has no sprite and is skipped as everywhere else'. True of our compositor, false of the game: the element is palogo_eff0.prm, which ui-forced-backdrop.md decodes as the full-screen opaque black backdrop, forced first, measured off the running game. The page's load-bearing draw order was pinned by a disc test and checked; the aside was not. The generalising phrase is the tell -- 'as everywhere else' is what turns a statement about our tooling into one about the disc. Also records that a refutation is exactly as wide as the job a claim was offered for: 37 of the 63 pairs differ without a button-count mismatch, where my reading is unsupported rather than refuted, and they wrote the bound when the wider version was available.

re: bgm-two-stems.md said the menu's bank is undecodable from the disc, and its own page decodes it
The Status line and the section heading both read 'undecodable from the disc' while a later section of the same page decodes it three ways, one of them static from the executable -- GamePart_Title's handler does li r5, 1103. A reader who stops at the top concludes the opposite of what the page establishes. The surviving content is the reason the CUE TABLE cannot answer it: 32 BGM cues named by number with no screen name, with SOUNDS, FILES and the bank headers all searched. A negative about one search location, written as a negative about the disc -- the same method-versus-subject error as the SE-audio heading, in the first line a reader sees. It propagated: the port's BLOCKED.md carries 'which BGM the menu plays -- not on the disc' in the same words. Found by applying sylpheed-port's 'get the category right' discipline to my own noisy impossibility sweep, after measuring what the false positives actually were rather than assuming they were infrastructural.

re: run the identity control on the coherence estimator -- it is exact, and the refutation strengthens
sylpheed-port disqualified a difference instrument of their own and named the rule: before asking whether an instrument can measure a difference, ask whether it returns zero for no difference. Mine had never had that test -- its positive control was a filtered copy at 0.94, which I had taken as the ceiling. Identity reads 1.0000 in every band, and a linear filter with NO delay also reads 1.0000. The 0.94 was entirely the 12 ms delay's windowing cost. So the ceiling for a filtered copy is 1.0 and the measured 0.027 midrange is further from it than the original control implied. It also adds an argument the first pass missed: a delay depresses coherence uniformly (0.9288..0.9380 flat), while the measurement is 0.027 midrange against 0.83 at HF. The shape is inconsistent with a delayed filtered copy too, which was the remaining route by which a rear pair could have produced it.

re: a bank's wave 1 is not a filtered copy of wave 0 -- and my own discriminator cannot finish the job
Coherence on BGM_103, the menu's bank, with controls run first: a real linear filter of wave 0 reads 0.93-0.94 in every band, a different bank reads 0.001, and wave 0 misaligned by 1 s reads 0.004-0.057. The measurement reads 0.027 at 1-4 kHz, so the 'wave 1 is wave 0 filtered' model is refuted. The frequency structure is inverted relative to any mic-pair or reverb model: coherence rises with frequency (0.169 -> 0.827) while energy falls (71 % -> 0.2 %), and a rear pair decorrelates fastest at HF. In the midrange the two waves are 13x further apart than the two channels of one wave. But the L-R control is what limits the tool and it is recorded as such: within one wave, genuinely one performance in two channels, coherence is only 0.221-0.497. So 'same performance' does not imply high coherence here, my positive control was the wrong model of the rear-pair reading, and the 🟡 is NOT settled. The tool tests for linear filtering and neither surviving reading requires it. Also corrects MISSION's Q10 row, which still carried the refuted three-sub-wave premise and had directed work at a dead question for days. Its gate is in fact met.

re: the sweep IS drawn on the JP title -- and my gate was phase-locking the shutter
The occlusion hypothesis is refuted: build 7 draws the same three ROT strips at higher alpha than English, so there was never an absence to explain. The 0.32-vs-11.9 tension that motivated it was an artefact of my own instrument. Both JP captures were shuttered on the plate pulse, and the plate's pulse is part of the animation -- so the gate synchronises the shutter to the animation's phase. Measured at the shutter instant, the sweep sits 25-26 px apart across two runs in different locales and different sessions: 1.6 % of a ~1600 px traverse. So the 0.32 I recorded as between-session capture noise measures my trigger's repeatability, and I read it as evidence the title is still when it is evidence the gate works. The era adjudication is unaffected -- margin 16.72 clears even the un-locked 11.9 -- and unaffected for the reason that file already gave: correlated noise cancels in a margin. Refutation attempt on sylpheed-port's positional-mechanism rejection: FAILED, the claim stands. Its residual sits inside lit logos, and the logo ROI is byte-identical across five differently-phased frames in two sessions.

re: the gamma ramp write -- direct observation attempted, blocked by the build tree
ui-render-tone-curve.md records the game's gamma-ramp write as "inferred from a closed chain, not directly observed". The direct observation is a log in Canary's own DC_LUT write path, which /canary being read-write makes available. Wrote it; could not build it. The patch logs each completed 256-entry sweep with samples against the identity ramp the source documents (i * 0x3FF / 0xFF), so a written ramp is distinguishable from an unwritten one by reading the log. Recorded in the page in full so a future iteration with a working build can re-apply it. BLOCKED: /sylph-home/re/canary-build was configured with -S/work/xenia-canary and that path does not exist in this container. ninja fails at CMake regeneration before compiling anything, and reconfiguring against /canary would trigger a near-full Xenia rebuild -- not something to start on the way to one log line. Per "do not improvise around a blocker", stopped and wrote it down. REVERTED the patch and verified /canary byte-identical to its backup. Leaving instrumented source the running binary does not contain is the source-and-binary-disagree trap this session has caught three times; a later reader would find the logging in the tree and conclude it was live. Also of note for the corpus: the header edit initially failed silently because I chained it with `||`, which hid the failure -- the "assert every edit" lesson from four iterations ago, repeated. Caught by grepping for the symbol afterwards rather than by trusting the command. The ramp write remains inferred, not observed. What is new is the reach: the experiment is written and the obstacle is a build-tree path, not anything about the game.

re: sweep the SILENT instruction surface -- 5 files still named a dead gate
sylpheed-port refined my ranking: rank silent instructions above loud ones. All of theirs were loud -- wrong paths that error out and announce themselves -- while mine was silent: an inert env var returning a clean, wrong result. Only the silent kind manufactures evidence. The silent surface is enumerable, so this is a sweep rather than a sample: every environment variable the docs name, checked against the code. SYLPHEED_KF_TIME_SHIFT was still live in FIVE doc files after I fixed one last iteration. Two of the five were genuine hits rather than historical quotes: ui-resting-pose.md -- a RESULTS TABLE ROW labelled "with SYLPHEED_KF_TIME_SHIFT=1". Re-running it sets an inert variable, produces the DEFAULT row, and lets a reader conclude the two readings agree. A stale instruction inside a results table is the purest form of the evidence- manufacturing class. HANDOFF.md -- "experiment reachable via SYLPHEED_KF_TIME_SHIFT=1", a live instruction in the delivery contract. And a live gate exists under a DIFFERENT NAME that the docs never pointed at: SYLPHEED_KF_TIME_LEGACY, verified read at ui_layout.rs:595 -- the parser itself, not only the tests, so it does reach screen info and screen render. Both hits now redirect there. Beware the proxy, which is the trap the port named about their own "parsed" check: absent-from-code also flags SYLPHEED_DISC, XENIA_SRC and SYLPH_ISO, which are container paths the brief sets and no code reads. Absent-from-code is necessary, not sufficient, and I checked each rather than reporting the seven raw hits.

re: finish the --help audit -- a stale percentage and a missing noun, both shipped
The METHOD entry I wrote an hour ago says to read your tool's own --help as if a stranger wrote it. I had done that for ONE of sixteen leaf commands, which is the "a rule written down is not a rule applied" failure this corpus already records twice. Finished it across the whole surface. One survivor, and it fails in two ways at once. `screen render --settle` said a narrow window means the bundle never settles, "(42 % of them, mostly loop* fragments)". MISSING NOUN: inside `screen render`, "them" reads as the builds you would render. The 42 % is over composable bundles -- a different and much larger set including ~1 700 two-element fragments a user of that flag never renders. ui-settle-time.md states its population precisely; the help inherited the number without it. STALE: recomputed under the corrected reader, the composable figure is 862/2211 = 39 %, not 731/1758 = 42 %. The POPULATION GREW BY 453, which is the keyframe record-layout fix's signature -- it times a group's final pose, so bundles that previously showed one timed keyframe now show two and qualify. Third consequence of that fix not being swept, after fade_quads.py and screen-transitions.md's 0.87-4.08 s fade-in. And the share a --settle user actually faces is 38 %: 185 of 491 screen builds. Corrected in the help text with all three numbers and their populations, and in ui-settle-time.md, whose three-row table is marked pre-fix and superseded rather than edited in place. Verified by artifact -- the tool's --help output is quoted, not merely recompiled.

re: test the port's black-backdrop predicate disc-wide -- exact locally, rare globally
sylpheed-port proposed that a screen declaring a full-screen .prm at t=0 with fade == 0xff000000 is standalone, and one without it is composited: 12/4 across their sixteen exported screens, every exception independently known to be composited. They asked for it against archives they do not have. That is my lane. CONTROL: the predicate reproduces their split exactly. GP_TITLE's sixteen bundles give 12 with and 4 without, the four without being entries 0, 1, 2, 3 -- build_00, build_01, press_start, press_start_jp -- and the element names match (pteff00.prm, palogo_eff0.prm, pgloading_eff00.prm). Independent derivation from the disc, not a re-run of their tool. DISC-WIDE it is rare: 76 of 965 screen builds, 7.9 %. GP_STAGE_CLEAR 4/4, GP_SYSTEM 2/2 and GP_TUTORIAL 2/2 are all-yes; GP_HANGAR_ARSENAL is 0 of 390, and GP_READY_ROOM, GP_OPTIONS, GP_PAUSE_MENU and GP_GAMEOVER are all zero. So it is not a general standalone/composited test. GP_OPTIONS and GP_PAUSE_MENU are screens a player plainly sees as screens and declare no backdrop; read as "composited" the rule would make 92 % of the game's screens composited, which the archives do not support. What it appears to separate is narrower: screens that BEGIN FROM BLACK from everything else. A pause menu over gameplay, a hangar over a 3D scene and a plate over a title all lack a backdrop without being the same kind of thing -- the negative class is heterogeneous, which is what a two-way rule cannot express. For the port: exact within GP_TITLE, so --black for those twelve is justified from the file rather than assumed; do not carry it into the four archives they have yet to export, where in three of them it classifies every screen alike.

re: the crop is not why the box is robust -- and it questions "the leaf free-runs"
sylpheed-port could not transfer the masking rule to their screens and inferred a
precondition: my free-running element is a localised plate I can crop around,
theirs is a wide sweep they cannot. Tested against my own screen, that is wrong.
The JP title carries the SAME sweep -- the leaves are identical on entries 4, 5
and 7, which I established last iteration -- and it crosses the box:
two renders of build 7 on the settled plateau, t=135 vs t=240
whole frame RMSE 12.135 95 791 px
in the box RMSE 11.923 57 981 px <- the sweep IS inside the box
differences span y 70..674, x 128..1140; the box is y 54..476, x 389..776
So the crop did not exclude the mover, and the in-box between-session term of
0.3215 has no explanation in the crop. Which leaves a tension worth stating:
two RENDERS one plateau-phase apart differ by 11.9 inside the box;
two CAPTURES of that screen from different sessions differ by 0.32 there;
and the --at sweep of renders against a capture is flat to 1.2 across
t=135..240, despite those renders differing from each other by 11.9.
A metric cannot be insensitive to an 11.9 change unless what changed is largely
absent from what it is compared against.
Hypothesis, recorded as untested: the game may not draw these leaves on the
settled title at all, while our renderer poses them wherever --at says. That
would explain the flat plateau, the tiny between-session term and part of the ~40
residual together. It would also mean the port's "the leaf free-runs in the game
too" is not established by their evidence -- their two minima come from two
DIFFERENT screens, which can differ for reasons other than phase, whereas my two
captures are of the same screen and barely differ where the sweep would be.
Not claiming the leaves are invisible; that needs a draw-stream check for
pteff03/pteff03a on a settled title, which is one run. What is established is
narrower and enough to stop the inference.

re: measure the capture-phase term -- 4.6 whole-frame, 0.32 in-box
sylpheed-port overturned their own phase-0 result using the identical-leaves fact I gave them: the same leaf minimises at phase 240 against a title capture and 0 against a main_menu capture, so the best-matching phase is a property of when the shutter fell rather than of the game's rest state. A continuously sweeping element has no canonical rest phase. They warned that any whole-frame score against a single capture carries a phase term of ~1.0 RMSE. Measured on my own two JP sessions, which certainly differ in sweep phase (44 025 px differ in the band the leaf crosses): whole frame 4.566 sweep band x721..1241 4.088 the adjudication box 0.3215 Their ~1.0 understates it for this screen: a whole-frame score against one capture of the JP title carries ~4.6. Theirs is the leaf-phase component isolated in a renderer; mine is everything that varies between sessions -- the plate pulse alone contributes ~2.8, measured separately on the EN peak/trough pair -- and includes theirs. My margins are unaffected and now for a measured reason rather than an assumed one. The era margin of 16.72 sits against an in-box term of 0.32, and settle-vs-rest at 1.48 is 4.6x that term while remaining non-decisive against the render-axis plateau of 1.2, exactly as stated. Scoring the 388x423 box rather than the frame drops the between-session term from 4.566 to 0.3215, a factor of 14, because the sweep contributes at x 721..1241 and the box is mostly clear of it. That was NOT why I cropped -- the crop was to stop a local difference being diluted across 92 % of an identical frame -- so the robustness is luck. The rule it earns: score inside a region that excludes the free-running elements, and measure the residual term there rather than estimating it.

re: verify the sweep leaves' full extent -- port's table confirmed, plus a new fact
Attempted to refute sylpheed-port's leaf table by measuring it against the disc. It SURVIVES to the digit: ptloop01 -> pteff03, cycle span 600, x track -639..1521, scale (100, 600); ptloop02 -> pteff03a, span 720, x -839..1721, scale (100, 800). The existing ptloop_leaf_sweep_at.rs samples only t=340..540 -- a window chosen to compare two competing fits -- so it could never have shown the extent. That gap is what let my "ptloop01/02 do not free-run" claim stand: measured over the parent's 200x90 pivot rect, which a leaf travelling -639..1521 is almost never inside. ptloop_leaf_extent.rs sweeps the whole cycle instead. New fact neither of us had: the leaves are IDENTICAL on entries 4, 5 AND 7 -- the title, the main menu and the JP title. Same leaf names, spans, x tracks, scales and parent rest position. So the menu declares exactly the same sweep as the title, and the still-open menu question is about the game's behaviour rather than a different declaration. The quad is 400 px wide at scale_x 100 % -- not widened -- and scale_y 600/800 % makes it 1080/1440 px tall, taller than the screen. A full-height strip crossing the frame and going off both sides, which is why a phase-to-phase diff covers the union of two positions and looks frame-wide. And my own "centre running x~921->1041" was a 30-unit window of a 600-unit cycle whose centre spans -439..1721. A sub-range is not an extent -- the same caution as a pivot not being a bounding box, one level up, and I made both errors within a day.

re: WITHDRAW "ptloop01/02 do not free-run" -- I measured a pivot, not an extent
sylpheed-port noted that build 5's ptloop parent can be static while the leaf record animates, and asked me to check it against my table. My own corpus refutes my claim outright. ptloop-leaf-sweep-positions.txt -- written earlier in this same corpus -- records ptloop01.rat's nested record at loop length 600, whose leaf pteff03.t32 sweeps a 400 px-wide quad with its centre running x~921->1041 over t=340..370. The parent's declared rect is (441,270) 200x90. The leaf draws 300 px outside it: the parent rect is a PIVOT ANCHOR, not the drawn extent. Checked against the two JP captures: my measured rect differs by 0 px -- and so does the whole dead region y 270..450 x 480..960 around it -- while the band the sweep actually occupies (x 721..1241) differs by 44 025 px. The zero was measured where nothing happens. So the port's reading is right and now confirmed from the disc: parent static, leaf animates, and the two nested records cycle at DIFFERENT lengths, 600 and 720. My "single static keyframe" described the parent only. The era adjudication is unaffected -- its box overlaps the sweep band only at x 721..776, which shows no between-session differences. The menu-loop question is still unsettled after a second attempt, and the second attempt's failure REFUTES my diagnosis of the first. menu_loop_probe.py gated on the plate pulse (glyph in [500,2500] held 12 samples), fired at t=484.5 s with glyph 1723 -- a verified settled BOOT title, not the attract one -- pressed A, and the press was delivered ([file-pad] keystroke vk=5800 down/up, 8 RE-INPUT lines). Twenty seconds later all five frames still classified as the title (rmse ~67-70, margins 0.06-0.16, the "neither" signature; screen_id says title). So "the attract title accepts nothing" does not explain attempt 1, and the corpus's "the boot title accepts a single A, 2 of 2 runs" is no longer 2 of 2. METHOD: a declared rect can be an anchor, not an extent -- confirm an element draws in a region before diffing that region to ask whether it moves. navigation.md: confirm the screen changed, do not infer it from a delivered press.

re: ptloop01/02 do not free-run on the settled title -- and the menu is not settled
sylpheed-port found ptloop01/02 free-running in their renderer on the menu path, pinned them, and was explicit that pinning picks one pose rather than the game's: "a capture question, not a harness one". It is, and it lands in my lane. On the title it is now answered. Those leaves rest at (441,270) 200x90, INSIDE the box the ptlogo_eff3 era adjudication uses, and across my two JP captures from different sessions they are byte-identical: 0 of 18 000 px, max |d| 0, against a whole-frame contrast of 116 492 px differing. So they are static at rest, and the in-box between-session noise of 0.32 is not theirs -- the 645 differing pixels all lie in a 30-row band at y 99..128, nowhere near the loop rect. That also closes the reach caveat on the EN->JP noise transfer. The MENU is a different bundle and is not settled. Build 5 declares the same rect with a single static keyframe, and that is where their row drifted. menu_loop_rest.sh was written to capture five settled menu frames and diff the rect; it did not complete. The run reached a title at t=146 s and (A) did not take across six attempts -- the documented intermittency where the attract loop's title accepts nothing, unlike the boot title. Recorded rather than re-rolled. Two committed main-menu captures cannot substitute: they differ across 57 % of the surface (different geometries and capture paths), so the 88 % differing on the loop rect measures the mismatch, not the loops. The control fails and the comparison is void. navigation.md gains the trap that cost this iteration a run: kill -9 on xenia orphans /tmp/xenia-canary.lock, the next run-canary refuses to STDERR where a polling script never looks, and a probe then sampled a dead display for 484 s reporting `other` every 4 s -- because screen_id.py on an empty screen returns `other` and "not the title yet" is indistinguishable from "there is no emulator". Kill plainly so it clears its own lock, and assert the emulator is alive before entering any wait loop.

re: a second JP capture closes the transfer -- and corrects my own noise claim
Last turn I transferred the EN title's capture noise to the JP box and flagged the gap: build 7 carries ptloop01/02.rat which may animate inside that region where the EN plate does not, and the era adjudication rests on a single capture. Took a second, independent capture from a fresh boot in a separate session (jp_title_session.sh -- sets ja, captures, always restores en; verified back at language=1). Within-run stability reproduces: 0 of 138 600 px in the ROI across four comparisons, with 47k-73k px moving whole-frame as the contrast control. BETWEEN SESSIONS, inside the box the adjudication uses: 645 of 164 124 px differ, RMSE 0.3215, against 116 492 px whole-frame -- genuinely different sessions. And the verdict reproduces to three decimals: stale 58.412 -> 58.413, fixed 41.690 -> 41.692, margin 16.722 -> 16.721. The shape is the useful part: capture noise moves both candidates together, so it nearly cancels in a MARGIN. Absolute scores moved 0.001-0.002 while the margin moved 0.001 against an in-box noise of 0.32. A margin between two renders scored on one capture is far more robust than either score is. CORRECTION to a claim I made earlier today and sent to the port: I said the settle-vs-rest negative was STRENGTHENED because 1.48 sits below the whole-frame capture spread of 2.8. Wrong comparison -- the measurement lives in the box, and in-box between-session noise is 0.32, so 1.48 is well above it. The negative rests on the render axis alone (1.2, ratio 1.2x), exactly as first stated. I reached for a number that was to hand rather than the one that applies, which is the same family as the errors we have both been cataloguing. METHOD gains: match the noise floor to the quantity, including which noise applies; and sylpheed-port's point that an instrument which rounds away the thing being verified cannot verify it (they called a harness reproducible from an RMSE printed to two decimals when the residual was 0.0565).

re: measure the CAPTURE-axis noise floor -- 0 in-box, and the era result survives
sylpheed-port found their main_menu row drifting 13.25-13.30 across runs on a free-running spin clock, and made the general point that a margin only means something against the noise it sits on. My --at plateau measures the RENDER axis; it says nothing about how much the score moves between two CAPTURES of the same screen, which is what a single JP grab is exposed to. Measured from two independent captures of the settled EN title at different phases of its free-running plate pulse, scored against one render: whole frame peak 31.302 trough 28.463 spread 2.839 inside the box peak 21.230 trough 21.230 spread 0.000 The zero carries its control: the two captures differ by 83 496 px whole-frame (max |d| 174), so they are genuinely different grabs, and by 0 inside the box -- the screen's free-running element is the plate, which lies outside the logo region the adjudication uses. Margins re-stated: stale-vs-fixed 16.7 is 14x the render noise and >=5.9x the whole-frame capture noise, so the era result survives on both axes. And the settle-vs-rest negative is STRONGER than first stated: 1.5 is not merely inside the render plateau's 1.2 flatness, it is below the whole-frame capture spread of 2.8 as well. Reach recorded: this transfers the EN title's capture noise to the JP title's box, and build 7 carries ptloop01/02.rat which may animate inside that region where the EN plate does not. A second JP capture would settle it and has not been taken.

re: an uncontrolled capture instant, and why the ptlogo_eff3 result survives it
sylpheed-port's harness grabbed main_menu at t=9.00 in one session and t=8.00 in the next. One keyframe unit apart, mid-build-in, is 70 % of the picture, and it read as "the change broke two screens" -- a real measurement of the wrong thing. The instant was stable WITHIN a session and drifted BETWEEN them, so every cheap reproducibility check said deterministic. Their flags are their harness's, not sylpheed-cli's (checked: `screen` has only list/info/render), so the tool defect is not in my crate -- but the hazard generalises to every live capture here. It would void this iteration's ptlogo_eff3 adjudication if the JP capture had been taken at an arbitrary moment. It was not, and for two independent reasons recorded rather than assumed: the grab was gated on the plate pulse, the title's own settled signature, with the gate and a contrast control written beside the capture in jp-title-at-rest.txt; and the --at sweep shows the capture on a plateau flat to 1.2 RMSE across 105 units against edges at 78, where a capture caught mid-build would give a sharp minimum. The sweep was run for a noise scale and answers this too -- which is luck, so METHOD now names both defences. METHOD: pin a capture's instant explicitly, and do not infer stability from repeat runs inside one session. Gate the grab on a settled signal prospectively, and sweep --at retrospectively -- a broad flat minimum with sharp edges means at rest, a sharp minimum means the instant is load-bearing.

re: the record-layout fix is confirmed against the GAME, and settle-vs-rest is not
The era test left one element responsible for all 74 507 differing pixels on title_jp -- ptlogo_eff3.t32, the corpus's named plateau-less rest() discriminator -- with two candidate rest poses, (108,72) stale and (98,42) fixed. There is a capture of that exact screen, so the oracle can choose. Scored over the 388x423 box where the two renders differ, so the result is not diluted by the ~92 % of the frame that is identical: stale era rest (108,72) RMSE 58.412 fixed era rest (98,42) RMSE 41.690 <- the game agrees with the fixed era fixed era --settle t=213 RMSE 40.210 Until now the keyframe record-layout fix rested on internal consistency: 0 of 1 042 multi-segment alpha ramps constant-rate under the old reading against 857 of 1 540 under the new. Strong, but not a measurement of the game. It now has one, on the single screen where the two readings change pixels. Three controls, all run first. Alignment found by sweeping the vertical offset rather than assuming it -- 45 gives 32.41 against 56.37 and 53.08 either side, a sharp minimum at the known game-surface offset. The scoring box discriminates: the same box against a different screen's capture gives 98-103 against 40-58 here. And --black changes nothing (58.412/41.690 either way) because every pixel in that box is covered by an element -- recorded because the flag's help says a framebuffer capture must be compared against a black canvas, and here it happens not to matter. Sweeping the screen's own timeline with --at gives the noise scale: the capture sits on a plateau from t~135 to t~240, flat to 1.2 RMSE across 105 units, rising sharply outside (78 at t=0 and t=270). So the stale-vs-fixed margin of 16.7 is ~14x that flatness and decisive, while the settle-vs-rest margin of 1.5 is INSIDE it and is not. This capture separates the eras and cannot separate the policies; the settle-instant proposal stays unadopted. Refutation attempted: sylpheed-port's adjudication that their shipped pose is closer to the game than their reference. It SURVIVES, independently and by a different metric, in the same direction. Also concedes that my "your branch is the stale era" reasoning was invalid -- I inferred era from a line count, which is the error they named -- while recording that the conclusion holds for the ref I could see: origin/auto/port-p6-audio's ui_layout.rs is md5-identical to origin/main's. METHOD: two things that should differ producing identical output is a broken experiment until proven otherwise, and a zero is its most dangerous form. Four instances now. Verify the inputs differ before believing the outputs match, and do not infer that difference from a proxy -- line count is not era.

re: sweep the disc for the ordinal foot-gun -- GP_TITLE was the mildest case
Last iteration I retracted three claims because `--build 10/11` on GP_TITLE are entries 12/15, and named the untested remainder in my own report: how much else in the corpus used a build ordinal as an entry index. This is that sweep. `screen --build N` indexes a predicate-filtered list, so every rejected entry shifts every later ordinal. Disc-wide: 21 of 24 build-bearing archives diverge, 18 of them at ordinal 0 -- `--build 0` is entry 108 in each GP_MAIN_GAME_*2D, 24/26 in GP_HANGAR_ARSENAL/GP_READY_ROOM. GP_TITLE is the ONLY archive whose first ten ordinals are the identity, which is the sole reason 207 of the corpus's 226 build citations are safe. Second foot-gun: `--all` swaps the predicate and renumbers 18 archives, so `--build N` and `--build N --all` are not the same object. The instrument failed its control first. A version using parse_build as the predicate reported GP_TITLE as 16 builds, ordinal == entry throughout -- it would have certified the exact bug it was built to find. The shipped version uses the same predicates screen_builds() uses and reproduces `screen list` on GP_TITLE exactly. Audited all 226 citations. One real defect: a five-row table in ui-keyframe-time-unit.md headed "declared element (build 11)" spans builds 10 and 11 -- palogo_sqex is in 10. All five placements re-verified and correct, so the linear-ramp measurement is untouched; only the label was wrong. Fixed with a per-row bundle column. GP_DIALOG --build 0 and GP_DEBRIEFING_PILOTLOG --build 10 re-run and reproduce. Refutation attempted: sylpheed-port's corrected mid-ramp test rests on ptlogo_all_eff holding a=127 from t=112 to t=246. Their quote is exact and it is a plateau. The refutation fails; their correction stands. METHOD already carried the rule I broke, and ui-splash-addressing already said the splashes need --all. The failure was not missing knowledge -- it was addressing a bundle by index without grepping for the index first.

re: RETRACT the splash settle windows -- --build takes an ORDINAL, not an entry
The port recomputed the publisher splash's widest keyframe-free gap as 190 units against my 8 and said one reading must be wrong. Mine was, and the library was never wrong -- only my invocation. From the file: entry 10's union of times is [0,15,30,45,235,239,251,255], widest gap 190, and settle_window() returns Some((45,235)). Entry 11 gives 145. Both match the port exactly. The cause is that screen render --build N takes a BUILD ORDINAL. screen list says [10] entry 12 and [11] entry 15; the splashes are entries 10 and 11 and are not screen builds at all, so my --build 10/11 rendered the LOADING screens. This is the foot-gun HANDOFF already documents, which the port caught months ago in the mirror direction. Three retractions: 1. 'Width does not predict quality' -- withdrawn. It rested entirely on the splashes being width 8 while winning 75x. They are the widest of the five, so width and mid-ramp are perfectly confounded across every screen either of us has measured and the width hypothesis is NOT refuted. 2. 'My filter excluded the splashes' -- withdrawn; at 190 and 145 they were never near the 10-unit cutoff. The other half stands: it admitted the 10-19 bucket, the worst at 45.1 %. 3. The splash rows of settle-vs-rest-against-captures -- void. They scored loading-screen renders against splash captures. I discarded them for a railed gamma fit; the real reason is that they were the wrong screens, and the railing was that mismatch surfacing where my instrument could report it. Surviving: the title row (ordinal 4 = entry 4) and the disc-wide censuses, which iterate pak entries directly and never touch the ordinal path.

re: census the settle pose's own failure mode -- and refute the obvious explanation
The port found ptmsg, the main menu's footer, at alpha 127.5 at that screen's settle instant. Verified: build 5's window is [44,56] = 12 units and screen render --settle already prints 'narrow -- this bundle may never settle'. Disc-wide, elements caught mid-ramp at their screen's settle instant: 25.5 % overall, 40.9 % on windows under 10 units, 45.1 % on 10-19, falling to 11.7 % and 15.0 % on wide ones. The obvious reading of that table -- narrow window means the settle pose is bad -- is REFUTED by the screens that motivated the proposal, and I nearly published it. The two splashes have an 8-unit window, narrower than the main menu's 12, and the settle pose beats rest() there by 75x and 33x. Width does not predict quality. The predictor is the port's own statement: the settle pose wins decisively where rest() lands on a transient's peak, and loses slightly where rest() is already sound and an element arrives after the window closes. And my own rest_vs_settle filter was wrong in both directions: dropping bundles under 10 units admitted the 10-19 bucket, the worst at 45.1 %, and excluded both splashes at width 8 -- the strongest evidence FOR the proposal. A threshold taken from a documented rule of thumb and applied without checking which screens it admitted and which it threw away.

re: rest_plateau() picks the wrong plateau -- and it is the whole residual
rest_plateau() selects the LONGEST run of identical adjacent poses, which need
not be the run covering the screen's settle instant. rest_vs_settle left a 21.9 %
disagreement that I recorded as ambiguous by construction. It is not.
CONTROL exactly one plateau, covering the settle instant:
3 072 / 3 072 agree (100.0 %)
TEST more than one plateau, at least one covering:
1 622 elements, agree on 586 (36.1 %)
of the 1 036 disagreements, rest() landed on a run NOT covering the
settle instant: 1 036 -- all of them, no exceptions
Both poses are genuinely held in these cases -- they are plateau cases, not
transients -- so this is rest() returning a pose the screen has ALREADY LEFT by
the time it settles.
This corrects my own METHOD entry of two iterations ago, which said a candidate
cannot be adjudicated against the incumbent it replaces. Too strong. The bare
comparison cannot; the comparison plus a structural property that independently
says which side is wrong in each disagreement can. What I lacked was not an
oracle but a discriminator.

re: settle_time() itself beats rest() against the game -- on the one screen that adjudicates
Closes the gap the port named: it ran my proposal against captures 3/3 in favour, but tested ITS OWN settled pose rather than UiBuild::settle_time(). Geometry established first, because my first attempt got it wrong: a 1280x720 render meets a 1279x675 capture by CROP, not scale -- crop rows 0..675 gives RMSE 14.07 against 68.89 resized and 79.61 for the 45-row crop. The 45-row offset holds for a full display frame; these captures are already the game surface. Gamma fitted per pose so neither candidate can win on the fit: title settle g=0.84 RMSE 8.17 15.28 % >8 title rest g=1.04 RMSE 20.92 70.84 % >8 The two splashes DO NOT ADJUDICATE and are not counted: their gamma fit rails at the edge of the search range, still railing when widened to 0.30..3.00, so the photometric model is wrong for them -- and with gamma railed their margins collapse to 1.16x and 1.06x. title adjudicates at an interior gamma and does so decisively, 4.6x on differing area and 2.6x on RMSE. So the IMPLEMENTATION and not merely the direction is supported. Absolute agreement is poor -- the port's settled title row is 0.21 % where mine is 15.28 % -- so the ordering is what this table carries, not the values. The port's three-screen result remains the stronger evidence.

re: propose settle-instant posing -- and my control cannot validate it
The proposal: pose every element at the SCREEN's settle instant rather than asking each element for its own resting pose. On the 2 249 fallback elements in settling bundles the visible-pose rate falls 73.6 % -> 34.7 %. But the control fails twice. Naive, over every plateau element: 46.6 %. That one was misspecified and I caught it by asking what the number means physically -- rest() finds *a* held pose and many elements hold one during the build-in then move on, so it answers a different question and disagreement proves nothing. Restricted to elements HOLDING ACROSS the settle instant: 78.1 %, still not a pass. And the residual is ambiguous by construction: rest_plateau() picks one plateau, so an element with two whose settle instant falls in the other will disagree -- and there pose_at(settle) is RIGHT. The control cannot separate 'the candidate is wrong' from 'the incumbent is wrong'. Recorded as the general point: comparing a candidate to the incumbent cannot adjudicate when the incumbent is the thing under suspicion. It is the wrong shape of experiment, not a tuning problem. What does adjudicate is the oracle and it is the port's measurement, not mine -- publisher splash against a committed capture, settle-instant pose RMSE 2.17 / 0.01 % differing against --pose=rest 9.05 / 0.75 %. My numbers describe the proposal's effect; they do not establish it.

re: my own 1697 audited -- and the first correction failed its control
Applying the port's physical-story rule to my own number. '1 697 fallback fires return a visible pose' was published as if it were a defect count; it is not, since an element that genuinely ends visible should rest visible. The first correction split the 1 697 by whether the element's LAST keyframe is visible: 347 correct, 1 350 transient peaks. Plausible, arithmetic fine, and WRONG -- 12 278 of 13 991 elements (87.8 %) end at alpha 0 because a screen's exit ramp drives everything to zero, so the split carries almost no information. The 1 350 is not published. What survives needs no such split: the fallback runs only when no two adjacent poses are equal, i.e. only when no pose is held, so every pose it can return is un-held by construction -- and 1 457 of the 2 305 times it returns the element's MAXIMUM alpha, the brightest un-held pose. I ran that control only because the port had just been bitten by the same exit ramp, its census calling ptmsg -- the main menu's permanent footer -- 'a 2-unit flash'. Without its message the 1 350 would have shipped. METHOD gains the sharpened form: the physical-story test catches confident FALSE claims, not just nulls. A wrong number usually still has a story, just an absurd one. Plus the tell that its fix was right -- re-keyed on the screen's span, the false positives fell out on their own, and a definition that stops needing hand-maintained exceptions is usually the correct one.

re: the port's two extra elements are PLATEAU cases -- refutation succeeds, and its point gets bigger
The port listed palogo_gamearts_eff and palogo_seta_eff among GP_TITLE's four visible dwell-fallback fires; this census listed only palogo_sqex_eff and palogo_anima_eff. Checked, and the census is right: gamearts_eff and seta_eff hold a=255 at identical x, y and scale from t=15 to t=30, which is a plateau at pair index 1, so rest_plateau() handles them and t=15 is the CORRECT answer. They are not fallback cases. The distinction is not cosmetic -- a plateau is a pose the element genuinely holds, and only the dwell fallback is the unsound path. But the refutation makes the port's underlying point STRONGER. Its rest pose for those two really is the flash's peak, reached by the SOUND path. So 'a rest render is not a frame to score against a capture' does not follow from the fallback being unsound: a plateau can itself be the held peak of a transient. The rule covers both paths, and the fallback census understates the exposure rather than bounding it. Also records the port's oracle number for the rule -- publisher splash against the committed capture, timeline RMSE 2.17 / 0.01 % differing against --pose=rest 9.05 / 0.75 %, 75x the differing area.

re: the rest() fallback -- its example dissolved, the question got bigger
ui-resting-pose.md built its dwell-fallback section on GP_TITLE build 7's ptlogo_eff3.t32, listing keyframes [46, 61, 103, -] -- the STALE PARSER's output. Corrected they are [0, 46, 61, 103], the longest gap moves from 61->103 to 0->46, and BOTH ends of the new longest gap are a=0. The element no longer selects a visible pose under either indexing, and build 7 renders byte-identical under the corrected and legacy readings (0 px differ). MISSION lists this element as the one case a Japanese capture was needed to discriminate; it is not. But losing an example is not closing a question, so: disc-wide census. The fallback fires on 2 305 of 13 991 elements and returns a VISIBLE pose in 1 697 of them -- 74 %. GP_TITLE is 5 fires, 4 visible, and all four are on the SPLASH screens: palogo_sqex_eff and palogo_anima_eff, each [0:a0 15:a255 30:a212 45:a0], a flash peaking at 15 and dead by 45 where the fallback returns t=30 a=212. Independently converged on from the other side: the port, working from the JP capture and knowing nothing of this census, found ptlogo_back2eff1's rest.t at the peak of its own 4-unit sparkle with six staggered across the logo, so --pose=rest fires every sparkle at once -- a frame the game never shows. Consequence recorded as a rule: a render posed at rest is a legitimate common reference for comparing two DECODERS and is not a frame to score against a capture of the game.

re: a .tbm DRAWS -- the TUTORIAL screen captured, and the 'inert' reading refuted
Closes the open second reading in ui-forced-backdrop.md: that a .tbm contributes no pixels, leaving 24 of its 62 deciding verdicts harmless rather than correct. The TUTORIAL screen was reached and captured. It carries a full-screen blue circuit/hex background. GP_TUTORIAL build 0's element 0 is pubase.tbm with pivot (640,360) -- 1280x720, the only full-screen TEXTURED element in the bundle; the one other full-screen element is pueff00.prm, an untextured primitive the colour census puts at pure black. Our render of the same build is the identical layout on pure black, 6.0-6.4 % inked against the game's 99.7 %. The only difference is the background and the only thing it can be is the .tbm. So the 24 .tbm verdicts are correct rather than harmless, and they are load-bearing in the full sense. Reach: one .tbm observed; the class question is settled, the ten other families are not individually seen. Also: screen render is wrong on every screen carrying a .tbm -- it drops the background silently, with no diagnostic. And the identification is worth its own METHOD entry. Two statistical identifiers were built. Masked correlation FAILED its control, picking EXTRAS over the known main menu by 0.004 because the shared background dominates. A high-passed variant PASSED by 1.28x, which is not a margin that licenses identifying an unknown, so it was not used. The screen says TUTORIAL across the top. Ask whether the artefact already states the answer before building a matcher.

re: a submenu is REACHED -- and correlation cannot identify it
Third attempt at the .tbm question. All three fixes from the previous page were applied and all three were needed: hold A for 0.5 s, confirm delivery from [RE-INPUT] rather than from the pad, and detect the screen change instead of timing it. Title at 288.6 s, both presses delivered on attempt 1, submenu at 303.4 s with 87.1 % of pixels changed. The capture is 99.7 % inked and uniform top to bottom -- a full-screen background. Our renderer gives 1.9-3.0 % for all 19 GP_SAVE_LOAD builds, 6.0-6.4 % for GP_TUTORIAL, 78.4 % for GP_SYSTEM 0/1. So two of the three archives render essentially nothing where the game draws a full screen. But WHICH screen was captured is not established, and the reason is worth more than the run: correlation cannot discriminate when the candidate renders are near-blank. All 19 GP_SAVE_LOAD builds score -0.004..-0.010 -- a ranking with no information. A matching statistic is useless against a hypothesis that predicts an empty image, which is exactly the hypothesis under test. Focus could not be read either: the two labelled menu captures fit at 2.52 and 2.48 mean absolute difference, 1.6 % apart. That is a SECOND statistic failing on the focus problem after the per-row brightness one, so it is an open item rather than an oversight. Kept regardless: the game surface sits at y=45 in the 1280x720 display frame, fitting the committed 1279x675 captures to 2.5 mean absolute difference. That is the alignment the earlier cross-geometry comparison got wrong.

re: run 'grep the corpus for the claim' on this corpus -- four still standing
Applying my own METHOD entry one iteration after writing it found four refuted
statements still asserted unmarked where a reader lands:
* envelope correlation 'has no resolving power' -- in three places including
HANDOFF. The port controlled the same estimator on a single track and got
r=1.0000 at zero offset; the saturation needs CONCURRENT streams sharing
timing. I agreed to this in a message and never landed it.
* '8 of 10 three-chunk regions' -- still asserted in HANDOFF in a different
section from its own correction.
* 'r9 is a wild pointer, never a guest address' -- still asserted inside the
kept-for-the-record section.
* the ALSA channel permutation, stated without scope, when a later capture
measured the identity and labelling from it put the silent channel on the
wrong name.
All four marked in place, striking the sentence and pointing forward.
Two lessons added: a 'kept for the record' section still asserts, so labelling
the heading is not enough; and naming a refuted claim keeps it greppable, so the
audit returns its own corrections as hits and every hit needs reading.
The first item is the one worth admitting: I acknowledged that correction in a
message, wrote the entry about corrections that never land, and then did not land
my own for a full iteration.

re: the .tbm submenu is not reached -- and the second tap was never delivered
Two runs, neither answering whether a .tbm draws pixels. Run 1 TIMED the title->menu transition and was still on the title 8 s later (glyph 714, the plate's pulse trough), so the second tap did the transition and the 'submenu' capture is the menu. Void. Run 2 DETECTED the menu instead -- glyph 327, matching live-main-menu.png exactly -- tapped 0.8 s later, and 12 s after that was still on the menu. The log says why: 2 file-pad vk=5800 lines, i.e. ONE press, and one RE-INPUT delivery. The second tap was never delivered, with zero swallow lines so it is not the sign-in path. A 0.12 s press issued while the guest is still loading a screen is missed outright. So 'the press did nothing' and 'there was no press' look identical from the screen, and only the log separates them. Worth more than the run: this is the third time in one iteration that timing was used where detection was required -- the title->menu wait, the menu->submenu wait, and the press itself. Each fix is the same substitution, and each was written only after the timed version had produced a confident wrong answer. Also records that no focus detector is needed for this question, since every main-menu destination except EXTRAS carries a .tbm decider.

re: land the loop-point correction where the claim actually lives
The port found its exporter still shipping 'no loop-point field has been identified anywhere' in the field manifest.json concatenates, days after the correction existed in other fields. Auditing this corpus the same way found the same failure here: the refuted sentence was still standing untouched in bgm-two-stems.md -- where anyone looking up BGM behaviour arrives -- and in HANDOFF.md, the one page the port is told to read. My correction had gone into a NEW page only. Both fixed in place, each naming the refutation rather than quietly deleting the old claim, and each carrying the measured window [9.44, 71.31] s at 61.87 s. METHOD entry: writing a correction down is not landing it. Grep the corpus for the CLAIM, not for the file you were working in. Plus the port's trap in doing that audit -- a replacement that quotes the refuted sentence in order to name it will match a substring search from inside the paragraph saying it is false.

re: the menu loop starts at 9.44 s -- measured, and the fix was scheduling
Tailing the log from BEFORE the music starts cut the unsampled backlog from 616
samples spanning offsets 32..2,559,033 to 125 spanning 32..515,239, so the first
pass is sampled like any later cycle. Offsets below loop_start play exactly once,
which is why the previous run could not measure them.
Wraps at 96.46 / 158.33 / 220.21 s, gaps 61.87 / 61.87, both contexts together.
Two derivations, neither converting bits to seconds:
(a) time to read_offset crossing loop_start, plus a 1.33 s head correction at a
rate measured on 748 timestamped samples of that same stretch
(b) first pass (offset 32 -> loop_end) minus the cycle
Both give 9.44 s on both contexts -- four numbers, one value.
So the loop region is [9.44, 71.31] s of an 87.744 s wave, cycling every 61.87 s.
The first 9.44 s is an intro played once; the last 16.4 s, the fade-out
bgm-two-stems.md documents, is never played at all.
The decoder reads ahead of playback, but both endpoints are read_offset events so
the lead cancels in the difference. One boot, one bank.

re: the menu loop WATCHED -- three wraps, 61.81 s, and my placement is refuted
Settles the conflict by timing the loop instead of converting it. A tailing probe stamps read_offset with the wall clock as each log line arrives, so the period needs no bits-to-time step -- the step already shown to be invalid. Three wraps, each exactly loop_end -> loop_start, and BOTH CONTEXTS WRAP AT THE SAME INSTANT all three times. That is the property two stems of one performance must have and the one the linear conversion could not deliver (62.34 vs 63.29 s would drift a second per cycle). Cycle 61.56 and 62.06 s, mean 61.81, against the audio autocorrelation's 61.93 -- 0.2 % apart from instruments sharing nothing. Linearity refuted a second time and internally: the fitted rate over 10..60 s is 341 394 bits/s while the cycle covers 22 034 741 bits in 61.81 s = 356 491 bits/s, 4.4 % apart inside one stream. My own audio locator's PLACEMENT is refuted. loop_start at 3.6 M bits is 11.6 % of the stream by any reading, ~10.1 s at the cycle's own mean rate, against the 0.25 s that page reported -- for the reason already suspected, that its control matched slices cut from the wave itself and never tested the aliasing the real problem has. The length was right and the span was wrong. Still not measured: loop_start in seconds. Offsets below it play exactly once and this trace stamped that whole stretch at t=0.002, swallowing the log backlog in one read, because it started after the music. The fix is to start the trace before tapping into the menu -- one line, not done.

re: the loop IS a runtime XMA field -- and reading it contradicts my audio measurement
No Canary patch was needed: UpdateLoopStatus already logs loop_start/loop_end, they just need the Apu category (--log_mask=13 --log_level=3). Decoded, from the menu, 8734 records all after BGM_103's contexts appear: ctx0 (wave 3876864) loop_start 3605682 loop_end 25640423 loop_count 255 ctx1 (wave 3930112) loop_start 3539158 loop_end 26216351 loop_count 255 The movie's three ADV streams log NO loop records -- they do not loop. Semantics visible in the trajectory: read_offset runs from 32 upward and 20 % of samples sit below loop_start, so the stream plays from the beginning and loop_start is where it returns AFTER loop_end. No wrap was observed -- the 45 s hold ended with read_offset at 17 M against a loop_end of 25.6 M. Two registered predictions REFUTED. loop_start is not ~0 but 11.6 % in. And a linear bits-to-seconds conversion is invalid: it gives 62.34 s and 63.29 s for two stems that must play sample-synchronously, which is impossible, so the data refutes the assumption on its own. That leaves a conflict I am not resolving: the field implies a cycle of roughly [10 s, 72 s]; my audio tracking reported offsets 0.25..57.18 s. Recorded as contested, with the likely weak link named as mine -- that locator's control used slices cut from the wave itself, exact copies, which is an easier problem than matching a real capture, and a control easier than the measurement does not bound its error. The port is told to change nothing: its trimmed 61.93 s loop is verified in its own output, and the length survives better than the placement.

re: count the voice-region population properly -- 25 three-chunk, and 17 of them were broken
Pays the debt from the truncated audit. The census prints population, coverage and skips in the same output, and ends with an explicit END line, so a cut-short run cannot be read as a complete one. POPULATION 104 movies; COVERAGE 95 resolved, 9 unresolved, 0 unreadable 70 one-chunk regions, 25 three-chunk regions The port's 25 was right; my '8 of 10' was not a count. Cross-referenced against the fix's own sweep, which also ran to completion (78 + 17 + 9 = 104): all 17 changed regions are three-chunk, none is one-chunk, and 8 three-chunk regions were never affected -- which the 1.5 MB cap predicts, since a region only trips the filter if its span exceeds it. So 'the defect is specific to the multichannel regions' survives with complete populations on both sides, while 'all three-chunk regions were broken' does not. The original 8-of-10 was wrong in its denominator and coincidentally shares a digit with the 8 that are unaffected, which is the kind of resemblance that carries a dead number into a later document.

re: the menu BGM loops at 61.93 s, and the game never reaches the fade
240 s parked on the main menu, reached by using the XMA probe log as the screen oracle instead of video -- the route the previous iteration wrote down. Menu in 26.8 s against never-in-378 s for the video rig, guest at 0.92x, capture at 0.08 % silence against the recipe page's own best of 0.31 %. BGM_103's contexts verify the screen and no ADV context appears afterwards, so the attract loop never took over. Three results, two instruments. NO SEAM: zero runs >= 0.3 s below median-18 dB in 232 s. The port's 3.4 s near-silence is a property of its authored loop, not of the game. NOT THE WAVE LENGTH: autocorrelation r at 87.750 s is -0.009 on four independent windows; the top lag is 61.909 s with a 2x harmonic. Estimator controls recover 87.750 and 60.000 exactly. 61.93 s, INDEPENDENTLY: locating 30 s slices of the capture inside the decoded summed waves shows playback advancing exactly +5.00 s per 5 s and wrapping at 61.93, from three wraps. Control: slices cut from the wave itself at 10/45/70 s are found at 10.00/45.00/70.00. Two points mis-lock where the slice straddles a wrap and they carry the two lowest scores in the table. Offsets span 0.25..57.18 s of an 87.744 s wave, so the loop is [~0, 61.93) and the final ~25.8 s is never played -- exactly where bgm-two-stems.md found the fade-out and trailing silence. The game loops before the fade, which is why there is no seam. Also corrects my own '8 of 10 three-chunk regions start mid-stream'. The port counts 25 three-chunk regions; it is right that both numbers cannot describe the same set. My audit run was CUT SHORT -- the committed file ends mid-list with no summary line -- so that was a ratio over an unknown fraction of the population, and the claim that the defect is specific to multichannel regions is now unsupported. The ADV verification and the fix's own sweep are unaffected; that sweep ran to completion and printed its totals.

re: the menu BGM loop is NOT captured -- and the rig that cannot take it
Recorded per 'do not improvise around a blocker'. The question is what the game does at BGM_103's loop seam, where the corpus has 'not a seamless loop, no loop-point field found, so the menu loop is authored' and the port measures a 3.4 s near-silent seam. Audio needs the ALSA tee; detecting the title needs video, so --gpu=null was unavailable. Measured twice: the guest runs at ~0.20x real time (76.5 s of audio in 378 s of wall clock) and the title is not reached in 300 s even after tapping A to skip the movie, with the tee's slave ending in a broken pipe and Xenia in underrun recovery. Not a crash -- rss 701 MB with 9.5 GB free, and the 'Killed' line is this harness's own cleanup. REFUTED along the way: CONTAINER-NOTES says --gpu=null runs here die at ~70 s. The intro-audio capture ran 148.02 s under --gpu=null and ended on its probe's timer with the emulator alive and the whole ADV movie decoded. More than twice the quoted lifetime. That note had been the reason not to use --gpu=null for anything long, which is exactly what a clean audio capture needs. The route left, written down rather than attempted: use the XMA probe log as the screen oracle instead of video. Sitting on the main menu decodes exactly BGM_103's two waves, so their byte_sizes appearing IS the menu -- which is better provenance for an audio question than a screenshot anyway.

formats: drop the 1.5 MB cap that truncated 17 voice regions' first stream
The cause, and the fix, with a disc-wide check. resolve_movie_voice_region picks start = the predecessor cue's trailer, then filtered it with 'end - s < 1_500_000' -- 'only within one bank'. ADV's predecessor sits 3 618 816 B before end, so the filter rejected it and start fell back to anchor, which is a TOC offset and not a stream boundary. That explains the shape of the defect exactly: it strikes regions larger than 1.5 MB, which is why the three-stream multichannel regions are hit and single-stream ones never are. 17 of 95 resolving movies took the fallback. ADV's predecessor trailer at 433 425 776 plus 17 040 B of descriptor and padding is 433 442 816 -- the -238-packet start measured against the decoder, to the byte. Dropping the cap: unchanged 78, fixed cleanly 17, changed in any other way ZERO. In all 17 the only difference is a larger first chunk with every later chunk byte-identical, which is what a corrected start looks like and what pulling in a neighbouring asset does not. Regression test pinned to the RUNNING DECODER's byte_sizes rather than to this crate's own output. That is the point of it: every internal check passed happily while a third of a stream was missing, so only an external number could have caught this class of bug. sylpheed-formats: 136 tests pass, 0 fail (the one still running at commit time is an unrelated long mesh test). Exact clips for the other 16 are not independently verified -- the sweep is strong but ADV is the only one with a decoder measurement behind it.

re: resolve_movie_voice_region starts INSIDE the first stream, 8 of 10 multichannel regions
Found because the port refused to apply my stream assignment and did the arithmetic instead: the running decoder's three ADV contexts sum to 3 584 000 B against a resolved region of 3 114 352 -- 15 % too small to hold them. Two spans, one wrong, and it was the disc side. The gap is 238 packets exactly (487 424 B), which is what a start offset looks like; ctx0 declares 632 packets and the resolver's leading chunk has 394. Verified against the decoder's own byte_sizes, which cannot be fitted to: at -238 packets to_xma_riffs yields [1294336, 1118208, 1171456], all three exactly. It is a real boundary and not the end of a sweep -- at -300 the previous asset's chunks appear while the three ADV sizes stay stable. Disc-wide: 24 of 24 single-chunk regions start at a boundary; 8 of 10 three-chunk regions start mid-stream. The defect is specific to the multichannel case. The audit's per-movie number is an UPPER BOUND, not the clip -- its stopping rule is the chunk count changing, and to_xma_riffs absorbs a few packets of the previous asset first (243 reported for ADV against a true 238). Only ADV has external ground truth. Consequence: in those 8 movies the leading chunk is a truncated first stream, not a spurious artefact, and anything measured on it was measured on a fragment -- including this corpus's own chunk-0 level, though the assignment survives because its ratio test was chosen to be immune to the clipping. The resolver is NOT patched. Why the predecessor cue's trailer lands 238 packets into the next asset is unanswered, and a fix guessed from one movie would be worse than a documented defect.

re: which ADV stream sits where -- settled by level, not by waveform
Completes ask #4. The three chunks were dumped from the resolved voice region and decoded; the assignment is ctx0 -> FL/FR, ctx1 -> FC with LFE silent, ctx2 -> BL/BR. Two instruments failed first and both look like results, so both are recorded. Envelope correlation with a per-pair lag search returns 0.86-0.95 for EVERY chunk against EVERY channel, because all six residual channels share the dialogue's activity timing -- that is an instrument with no resolving power, not a finding. Sample-level correlation returns about zero, because the chunks do not start with the movie and the XMA decode's framing offset is unknown. Level settles it under the same 0.600 gain the bed uses: each stream lands within 0.5 dB of exactly one residual pair and misses the others by 4-6 dB. The ratio test is immune to chunk 0 being a clipped tail of ctx0 -- chunk0 - chunk2 is +5.88 dB against FL - BL at +6.18 dB, agreeing to 0.30 dB, where a swap would be wrong by 11.76 dB. Structural confirmation: chunk 1 is the only chunk with a digitally silent channel and LFE is the only output channel with an empty residual (-115.73 dBFS), one to one; and the internal L/R correlations track the residual pairs' (0.932 vs 0.918, 0.962 vs 0.929). Worth having on its own: the same 0.600 scales both the movie bed and the voice, so it is one mixer gain rather than two. Reach: levels, not waveforms; one boot, one movie; and whether 0.600 is a fixed constant or a volume setting is still unknown.

re: ask #4 answered -- the intro is a 5.1 WMAPro bed at 0.600 plus three streams
ADV.wmv carries ONE audio stream and it is wmapro 5.1, not XMA. Any framing of the intro's audio as only 'which of three voice streams to ship' was missing the bed. Aligned the 148 s capture against that track (envelope r 0.769 against a median of -0.001, refined to +224 samples, r 0.900) and solved capture = g x movie + residual per channel. The gain is 0.600 on every channel -- a uniform -4.44 dB, a mixer setting rather than a fit artefact. LFE reproduces to -115.73 dBFS, 72 dB down, which is what rules out codec difference as the explanation for the other residuals. FC is the exception: the movie explains NOTHING of it (-0.09 dB), and the movie's own FC is 91.6 % silent. The residual is three signals, not one: a front pair (r 0.918), a rear pair (r 0.929), and a centre whose partner LFE is empty. The FC residual spans 34 dB across 100 ms frames -- bursty, not steady noise. That CONFIRMS the corpus's 5.1 reading, which voice-three-streams-are-concurrent recorded as not established, and it confirms the specific detail it offered: that the mono-in-stereo stream is 'a centre paired with a silent LFE'. Measured from the output with no access to the stream contents. Also corrects my own census page: it labelled channels with the ALSA permutation [0,1,4,5,2,3] from the recipe page, which does NOT apply to this capture. The 6x6 matrix was computed assuming no order, every row's max falls on a distinct movie channel, and the answer is the identity -- so the census's 'BR is 82 % silent' was really LFE, reconciling with the movie's own 80.64 % silent LFE. Reach: one boot, one movie; which XMA context is front/centre/rear is not determined, only that the residual occupies those positions; and whether 0.600 is a fixed constant or a volume setting is unknown.

re: the boot intro's audio output -- five live channels, not a stereo mix
Groundwork for the port's ask #4; it does not settle #4. Captured the game's own output over the boot intro following the ALSA file-tee recipe exactly -- paced pulse slave, --gpu=null, both mutes off. 148.02 s, 6ch float32 48 kHz, 0.15-0.16 % silence against the 0.31 % the recipe page records for its own clean run. Provenance is the XMA probe rather than a screenshot, which is the right evidence for an audio question: ADV's three contexts appear byte-exact (1294336 / 1118208 / 1171456), then the documented BGM_102 pair. Five of the six channels carry distinct content; BR is 82 % silent and 11-15 dB down. No channel is a copy of another -- the largest pairwise correlation is 0.70 between FL and FR. That rules out a stereo mix, so 'ship one stream' cannot be right and the port's held-wrong value stays wrong. It does NOT establish that summing is right, and the 6-channel count is Xenia's hardcoded kFrameChannelsDefault -- what is evidence is that five of them differ, which a stereo guest cannot produce. NOT settled and named as such: the stream-to-channel mapping. The cross-correlation of each captured channel against each decoded ADV stream has not been run. One boot, one movie, and --gpu=null means no video cross-check. Raw is 170 MB and is not committed; sent over share to the port.

re: the pulse floor gets a second witness, and two METHOD entries
The port reproduced the floor exactly (159) once the predicate was named, and counted an independent capture from a different session: 753 against this run's 714, a ratio of 4.7x against 4.6x. 'Never goes off' is no longer single-run. Two METHOD entries. A detector that can fire on a single frame will fire on the wrong one. The A/B's first pair was void because the title detector tested one frame against a glyph threshold and the intro movie throws sub-second green flashes of 1298..5433. The presses were real and skipped the movie, so both legs returned a clean, symmetric, meaningless result -- a void test that looks like it ran is worse than one that errors. Same shape the corpus already recorded for screen_id.py calling the SQUARE ENIX logo 'title'. Twice paid for. The rule is that a screen detector matches a signature over time, and a broken run's own series is the cheapest control for its replacement. A demand for reproducibility can surface a defect that is not the one demanded. The literal answer to 'your figures are unverifiable' was 'here is the predicate', after which they verified exactly -- but writing the method down is what exposed the cross-geometry floor comparison, which nobody was looking for. And both sides were wrong at once: the challenger's counts were the wrong measurement AND the published figure had a real flaw.

re: the A-press A/B is run -- signed-in profile, no swallow, menu opens
The debt from two iterations ago. Two boots, same binary and ISO, one A tap each, fired only after the plate's pulse had been seen for 12 consecutive samples. ARGV recorded per leg, because the config dump provably cannot say. leg A no profile flag 3811 swallow lines and climbing leg B --logged_profile_... 0 swallow lines, final glyph 327 = MAIN MENU 327 is the documented main-menu glyph count, reproduced by this instrument's own control, so leg B's press opened the menu. Capture committed. Leg A demonstrates the SWALLOW, not the crash: I stopped it at ~2.3 M swallowed calls because kernel tracing at log_level=3 was eating the 300 MB budget the crash dumps need. The fault itself remains measured once, historically. One run per leg. A void pair came first and is recorded, because it is why the detector is what it is. The first version fired on a single frame over a glyph threshold and hit the INTRO MOVIE -- green flashes of 1298..5433 lasting under a second -- about 6 s before the title, in both legs. The presses were real (each skipped the rest of the movie, which is Q9's behaviour) but the pair tested nothing. The fixed detector requires 12 consecutive in-band samples, and was replayed against the void runs' own series as its control: it declines the movie flash at 84.8/85.5 s and fires at 93.9/94.7 s inside the sustained pulse.

re: name the region and the threshold -- and the floor was cross-geometry
The port agent could not reproduce this page's 159/714/1520 from the capture it holds: counting green>150..200 over a plate box it got 3-5x at every threshold. The page named neither the region nor the predicate. Stated now: the whole 1280x720 frame, and is_title.py's three-channel predicate (g>130 & g-r>45 & g-b>45), which is why it counts far fewer pixels than a bare green>N. That reproduces 1520/714/159 exactly. Writing the method down exposed a defect the prose had hidden. The 159 floor came from live-title-build4-no-plate.png at 1279x675 -- the game surface -- while the pulse frames are 1280x720, the whole display. Different crops, silently compared. Replaced with a same-run, same-geometry floor that was in the series all along: 154, flat for ~2 s immediately before the plate ramps in. So 'it never goes off' now rests on one run in one geometry, at 714 against 154, which is where it should have rested from the start. The port's independent ratio of 1:10.4-10.9 brackets this page's 1:9.6 and is the part robust to how anyone counts. Two METHOD entries: a pixel figure needs its region and its predicate, and a comparison between two counts needs them to share a geometry; and the port's observation that a fix which overshoots leaves no symptom until a third change needs the part it disabled.

re: RETRACT -- a Canary config dump is the FILE, not the run
Refuted my own evidence with a direct test. The A-press fault page cited the faulting run's dumped logged_profile_slot_0_xuid = "" as proof no profile was signed in. Xenia prints its config dump BEFORE applying command-line overrides: in a run launched with --apu=sdl --hid=file --mute=true --log_mask=13, the dump says apu="any", hid="any", mute=false, log_mask=0. Four for four. So the dump is a statement about xenia-canary.config.toml and nothing else, and this page cannot know the faulting run's profile state. Anything in the corpus citing a config dump as evidence of what a run did is making the same mistake; to know a run's settings, record its argv. Survives: the mechanism (swallow -> unbounded pump -> failed allocation -> fault), which rests on the [RE-INPUT] counter and the crash dump's registers; and canary-scripted-input-traps.md section 3's measured sign-in-dialog claim, which has a capture behind it. Also records the port's base-plus-glow mechanism for the plate, which explains why the pulse floor is 714 rather than the plate-absent 159 -- ptbtn00's fade at t=244 is an exit ramp so the base holds at 255 while the screen is held, and ptbtn00f's 0->80->0 glow draws over it. Marked as agreeing with the measurement, not confirming it: their renderer is not an oracle. It does rule out a glow-only plate, which could not produce a non-zero floor.

re: the PRESS A plate PULSES -- measured, and it keeps an authored entry
Answers the port's ask #1, which it had flagged as the only one of its four that could delete an authored entry rather than confirm one. It confirms one. Held at the title with no input, the plate oscillates continuously: two windows in one boot, 58 s and 57 s, ~23 cycles each, no decay. Periods 2.530 and 2.540 s by upward mid-crossings -- 0.4 % apart. It never goes off. The plate-absent floor is 159 green pixels, measured on the committed live-title-build4-no-plate.png; the pulse bottoms at 714, 4.5x that. So the port's 'flash and nothing after', reasoned from ptbtn00 expiring at t=244, is wrong on the boot's end state -- ptbtn00f's 120-unit cycle is what runs. Instrument controls were run before it was pointed at anything unknown: the glyph counter reproduces the documented 753 on live-title-press-a.png and 327 on live-main-menu.png exactly. Two estimators, and only one replicates. Mid-crossings agree across the two windows to 0.4 %; a single-sinusoid least-squares fit does not (2.553 vs 2.413), because the waveform is fast-rise/slow-decay rather than sinusoidal -- its own r2 of 0.468 and 0.228 is the tell. Both were controlled on synthetic sinusoids at 2.24/2.55/3.10 s laid on the ACTUAL timestamps and recovered every one exactly, so neither is broken; one is misspecified. Recorded as such. The wall-clock is 13 % longer than the corpus's earlier 2.24 s mean. Same declared 120 units, different emulator pacing (x1.27 here against x1.12), so this corroborates 'author the units' rather than disturbing it. Reach stated: one boot; does not distinguish the boot title from an attract-loop title; and the glyph count is a thresholded pixel count, so 714/1520 is not an alpha ratio and no duty cycle can be read off it.

method: the mirror trap -- two records that drift, and a weakened control
Two corrections from the port agent, both of which make earlier claims smaller. 1. Its 'reproduces your published centres to half a pixel' was model against model. This corpus's 981/478 are the model's output at t=355, not the capture's; the capture measured 992.0/467.2, the 11.5 px residual the page declines to fit. So that control shows two implementations of one model agreeing, not the model matching the oracle. Neither of us applied the correlated-instrument test to that sentence at the time. The discriminator survives: it asks whether two captures are the same frame, and the model is monotone in t at ~4 px/unit, so a 42-unit gap cannot come out of one frame however wrong the absolute times are. Recorded as such. 2. Running my 'grep for the symptom' audit against its own tree, the port found the opposite failure: a control recorded in BOTH a tool table and a document, drifted to 53.3 % and 53.2 %, with the evidence file gone so neither can be re-measured. One hard-to-find record announces itself as missing; two disagreeing records announce nothing, which is worse. So the rule is not 'write it down twice' -- one record in docs/re/, everything else cites it, and any number that must appear twice is generated rather than typed.
