re: a false HEADING standing 78 lines above its own correction
sylpheed-port diagnosed their four instances of fixed-code-under-unfixed- description as a habit rather than inattention: corrections are ADDITIVE. They append a correction block and leave the original standing above it -- right for a record, wrong for a statement, because a reader takes the first assertion. Their fix is to keep the quote but demote it grammatically. Applied their diagnosis here and found a worse instance than theirs. screen-transitions.md carried the heading "### ❔ The fade-OUT duration is not in this field", with a section beneath it that is false in every sentence: "The fourth block has no time -- a group's last block stops 4 bytes short and that word is already the next group's element index. So the disc gives the ramp's target (black) and not its length. That duration is measured below, and the port is authoring it." All pre-fix. The record-layout fix times a group's final pose, so block 4 carries t=80 (menu), 74 (EXTRAS) and 269 (title), and the fade-out ramp is DECODED at 70->80 = 10 units, 64->74 = 10, 261->269 = 8. The section told the port to author a value that is decoded, and its correction sat 78 lines below. It also carried the dead rule's exact vocabulary -- "stops 4 bytes short" -- which is the grep I built for code last iteration and never ran against docs. Rewritten leading with the correction, the original quoted and demoted beneath it. METHOD: corrections are additive by default and that is wrong for a statement; the worst form is a HEADING, which asserts with maximum reach and minimum context, and a reader scanning headings never reaches the retraction. Audit headings first. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Wuu56cE8vJGTBtn1ppsk8v |

re: the black gap between screens is NOT a load -- measured, three legs
sylpheed-port's BLOCKED ask #2. The gap was the one quantity in the transition with no rule: measured at 0, 3 and 2 frames across three transitions, and I had proposed it might be a load, which would make it emulator- and storage-dependent and unauthorable. Leg 1, bundle size runs the wrong way. If the gap were the incoming bundle arriving, the biggest bundle would gap longest. Build 4 is 12 278 666 B and gaps ZERO frames; build 5 is 6 977 437 B and gaps 3 and 2. Leg 2, ran title->menu a second time from cold. The outgoing ramp is byte-identical (63, 127, 191, 255) and the gap is 3 frames in BOTH runs. Leg 3, and the two runs are not a null comparison -- which is the objection leg 2 invites. The captures refute it themselves: press-to-first-change differs by ~12 frames between them (~25 against ~10). Something in this transition really is cache-sensitive and moved by 0.4 s, while the gap did not move at all. The control comes from inside the measurement rather than from an assumption that conditions differed. So the gap is deterministic to the frame and not a load. It is also not constant across transitions (0, 3, 2, 3) and not in the fade group -- the port reports 866 keyframes across 16 screens with 0 untimed. A deterministic game quantity with no rule found; black_hold_units stays 0, and "not a load" must not become a reason to author a constant. The load proposal in screen-transitions.md is marked refuted rather than deleted. Also fills in docs/game/navigation.md, which the standing brief asks me to keep and which I had not touched while measuring four transitions: a player-side section on what a screen change looks like, and three scripting traps -- that `pkill -f xenia_canary` kills the shell that ran it (cost a launch today, and the same trap is already in METHOD for pgrep), that screen_id.py reports `menu` during the attract loop, and that it cannot tell EXTRAS from the main menu.

re: (B) from EXTRAS DOES go black -- "(B) has no black interval" refuted
sylpheed-port's BLOCKED.md ask #1. They declined to suppress their uniform black_hold on the cancel path because (B) menu->title was one transition. The test says they were right. EXTRAS -> main menu, also via (B): the outgoing quad ramps frames 34-38 (5 frames, exactly build 6's declared 10 units), then frames 39 AND 40 are completely empty -- 3 draws, zero textured, a harder black than either earlier capture -- then the incoming menu's quad decays 41-45. So (B) does not imply a cross-fade; menu->title is the outlier of three, and the generalisation I was one step from publishing is false. The screen was verified, not assumed. screen_id.py cannot separate EXTRAS from the main menu, so which_title_screen.py checked the armed frame: extras 18.58 vs main_menu 29.85, margin 11.27, inside the 9.9-11.7 band its control sets on four known captures. Three transitions now agree on one thing and disagree on another: outgoing ramp = the declared final ramp, THREE FOR THREE, against three different declared values (10u/5f, 8u/4f, 10u/5f), and exactly linear where nothing overlaps it. Authorable from the file. black gap = none / 3 frames / 2 frames. Not a per-button property, not a per-direction property, not a constant. black_hold_units should not be authored as one. Build 5's incoming ramp is confirmed at 12 units by its RATE rather than its count: the count came out 5 against a predicted 6 in both runs -- reproducible, so not noise -- but capture 3's steps are -21, -42, -43, -42, i.e. 255/6 per frame after a half-step start. Capture 2's decay does not fit that and is unexplained. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Wuu56cE8vJGTBtn1ppsk8v |

re: the decaying quad is the INCOMING screen -- and (A) and (B) are different shapes
Last iteration left an unidentified full-screen untextured quad decaying 255->15 during a menu->title transition, which build 5's declaration does not account for. Hypothesis: it is the INCOMING screen's own pteff00, which opens at a255 and clears. 8 frames matching build 4's declared 16 units is a FIT, so the test was a transition whose incoming screen declares something else: title->menu brings in build 5, 0->12 = 12 units = 6 frames. Prediction recorded before the run. Measured: menu->title decay 8 frames (incoming build 4, declared 8), title->menu decay 5 frames (incoming build 5, declared 6). Different incoming screen, different decay, in the predicted direction. The second is one frame short of prediction, inside the documented +-1. The tell that clinches it: a screen contributes TWO primitives, pteff00 at 255 and pteff02 at 64. The settled menu's untextured set is [64]; at frame 34 it becomes [64, 255, 64] -- build 4's opening pair, which no single element explains. Bonus, and it closes the alpha puzzle: in capture 2 the outgoing quad ramps with no other untextured quad present -- 63, 127, 191, 255, steps of exactly 64, four frames, against build 4's declared 261->269 = 8 units = 4 frames. Exact and exactly linear. Capture 1's 102/127/255 was a composite of two overlapping quads, as sylpheed-port proposed. The thing neither of us predicted: the two directions are not the same shape. (A) title->menu is SEQUENTIAL with a real black interval of 5 frames (~10 units, against the port's authored 9). (B) menu->title is a CROSS-FADE with no black interval at all -- the incoming title starts drawing at frame 34, before the outgoing menu's quad begins ramping at 40. Authoring one hold for both directions inserts black that (B) does not have. Also fixed: fade_pair.py's automatic rising/decaying classifier worked on capture 1 and produced nonsense on capture 2, where the title has no full-screen primitive at rest and the heuristic latched onto a transient. It now prints and does not decide. Refutation attempted: sylpheed-port's structural prediction of a 6-frame decay for an incoming menu. Measured 5. Survives as direction, one frame short as duration; recorded as both.

re: withdraw "the fade-out overlaps the content" -- it is a gap, and the port was right
sylpheed-port read the lead off the disc independently: content fade-outs start at ptmsg 58, pteff10/pteff12/ptbtn05 60, against the quad's ramp at 70. That reproduces my measured six-frame lead exactly (12 units = 6 frames) but has content FINISHING two units before the quad starts, where I had published overlap. Checked which draws I had been watching. The content sprites are TEXTURED: they fade over frames 34-37 and are gone by 39, and the black quad appears at 40 -- a one-frame gap, which is their two units. What overlaps the quad is a different, UNTEXTURED full-screen quad decaying 255->...->15 across frames 34-41. It is unidentified: build 5 declares only pteff00.prm and a single-keyframe pteff02.prm, neither of which is that decay. Recorded as an open observation, not named from one capture. So the shape is sequence, not overlap. Also flagged, against my own interest: their "18 vs 19, one unit apart" compares different intervals (content-start->black vs ramp-start->next screen), and the capture's frame axis is not phase-locked to the file's unit axis -- the two plausible alignments differ by two frames with nothing here to distinguish them. So that agreement holds at one alignment and is not a confirmation. The quad's alphas (102/127/255) also do not sit on a linear ramp across t=70->80, which is unexplained.

re: the transition is overlap, not ramp-then-hold -- and the fade-in was 5x wrong
screen-transitions.md carried a 14-unit "black hold" that the page itself flagged as arithmetic rather than measurement. Measured it against the running game; the guess was wrong, and finding the instrument to measure it turned up a second, larger error in the same page. 1. fade_quads.py was STALE. It read each pose's time from blk+36 -- the next record's time word -- the association the keyframe record-layout fix retired in the crate. sylpheed-cli was rebuilt at the time; the Python helper was never swept with it. Signature: it cannot time a group's last pose, so it printed a trailing `t=-`. Fixed, controlled against the rebuilt `screen info` ([0 12 70 80] for build 5's pteff00.prm). 2. Through it, the page labelled the quad's CLEAR-hold as its fade-in and published 0.87 s / 0.97 s / 4.08 s for a ramp that is 0.20 s / 0.20 s / 0.27 s. A port pacing its menu fade-in off that would run it 5x too slow. 3. The measurement. fade_decompose.sh boots to the main menu, arms the UI draw capture there, then presses (B), so one 260-frame window holds the whole screen change. The fade quad is identified rather than guessed: a .prm carries no tex[base=] and paints last, so it is the last full-screen untextured quad of a frame. Control first -- the quad's ramp is decoded at 10 units = 5 frames, and measures 4 submitted-frame steps with one unlogged frame in the span. Result: content elements begin fading at frame 34; the black quad first appears at 40 and is opaque by 43; the menu's last frame is 45; frame 46 has 6 draws against 12. So the ~14 extra units are the content's own fade-outs OVERLAPPING the quad's ramp, not a hold after it, and the inter-screen black is one frame. Refutation attempted: sylpheed-port's entries 13/14 twins. Re-derived off the disc -- 3.06 / 4.33 / 47.91, identical to two decimals. Recorded as confirming their addressing and arithmetic, NOT as independent support: same renderer, same disc, which is their own rule. Reach: one transition, one run; the frame axis has gaps (232 headers over frames 3..260), so every span is +-1 frame.

re: the CLI binary was STALE -- screen info's keyframe times were the old parser's
The copy of sylpheed-cli in this container was built 2026-08-29 12:38, before the keyframe-record-layout fix. The old parser shifted every time by one slot and could not time a group's final pose, printing a trailing '-': stale pteff00.prm 4 kf rest t=70 [12:0,0 70:0,0 80:0,0 -:0,0] fresh pteff00.prm 4 kf rest t=12 [ 0:0,0 12:0,0 70:0,0 80:0,0] Both outputs are well-formed and neither announces its age. That refutes the premise of screen-transitions.md's 2026-08-29 section, which argued from 'there is exactly one untimed keyframe, and every element has it'. There is no untimed keyframe, so the question it answered -- is 0.4 s the missing duration of that keyframe -- has lost its subject. The ratio test in the same section is untouched. And it decodes the number the port asked about: pteff00.prm's final ramp is 70 -> 80 = 10 units, about 0.167 s, not the ~24 this page authored. I tried to refute the port's 10 against the bytes and could not. So the measured ~0.4 s is NOT the ramp alone -- 24 units measured against 10 decoded. That the remaining ~14 units are exactly the black hold is arithmetic that fits (0.233 s, inside this corpus's own 0.17-0.23 s plateau) and is NOT a measurement; the decomposition stays open. CONTAINER-NOTES gains the trap. Renders are byte-identical across the two binaries (max per-channel difference 0 on GP_TUTORIAL build 0), so element identity, pivots, keyframe counts and screen render output are unaffected -- it is the times that move.

re(ui): answer four of the port's five asks -- splash, fade-out, focus, gamma
1 SPLASH ADDRESSING (was blocking P3). No content predicate exists: design size fails (every extra composable bundle sampled is 1280x720, like every screen) and element count fails (fragments run 2..15, the splash halves are 3 and 7). But GP_TITLE needs none -- `--all` adds exactly four bundles there and all four are real screens, with the --all index equal to the pak entry index 1:1. And there are TWO splash screens: 11/14 are the developer logos, 10/13 are the SQUARE ENIX publisher wordmark, which the port did not have and which the boot shows first. 2 FADE-OUT (was blocking P3). It is (a), and it is bigger than the fade quad. Every element ends on exactly ONE untimed keyframe, which rules out (b); that block is where the screen plays out -- quad to a=255, buttons/labels/glows to a=0, frames hold. (c) is refuted by a null test that discriminates: a black quad alone holds the button/background brightness ratio constant, and through the fade it falls 6.50 -> 1.94, 3.4x monotonic. 3 FOCUS (saves P5 rework). Over-vs-instead is unobservable -- the focused sprite covers the base at 100.0% of base-visible pixels on three pairs once aligned (true offset (7,7); the centre alignment reads a misleading 78-84%), and compositing both ways differs by RMSE 1.1 inside the button rect. The real defect is the focus record's SECOND element: ptbtn0Nf.rat declares ptbtneff01.t32 (a 42x46 glowing ring, focus only) plus the bright label, where the base declares one sprite. That ring is the marker the port draws nowhere. 5 GAMMA. The capture is not neutral: capture ~ 255*(render/255)^g, g ~ 1.34-1.49, and the chain says it is a ramp the GAME installed, not a capture artefact. So RMSE against captures has a floor. Reach stated: the flat patches are all dark (render ~0-60), so midtones and highlights are unconstrained. 4 ROTATION is a human's call and is recorded in MISSION, not acted on -- the port rotating while the reference renderer does not would make verify-screen report a large diff meaning "the port is right". The RE half is answered: rotation is about the declared pivot, measured against a GPU capture. The focus record's +20 element-count word is marked 🟡 not ✅ -- read on GP_TITLE's ten button records only; the disc-wide check is written and still running. |

re: the transition between screens is a fade through black, and most of
its timing is on the disc Q7. Every title-side screen carries a full-screen black .prm quad that paints last, and its keyframe group IS the transition: black at T0, clear by T1, clear until T2, then back to black on exit. Read with the corpus's start-of-a-ramp rule and Q1's time unit that gives 0.87s for EXTRAS, 0.97s for the main menu, 4.08s for the title -- from the file, not from a stopwatch. The disc-wide check is per-pak all-or-nothing rather than the 41% the headline count suggests, and GP_TITLE's 6 of 12 is the useful row: the six builds carrying a fade quad are exactly the six SCREENS, and the six without are exactly the six overlays. GP_DIALOG is 0 of 133. That is independent corroboration of the overlay finding from two iterations ago. One piece is NOT on the disc and says so: the fade-OUT length. The fourth keyframe has no time slot, because a group's last block stops four bytes short. Measured instead, at 30fps, ~0.4s and the same both directions. And a warning I earned: the luminance rise after a transition is NOT the quad's ramp. The incoming screen's own elements animate in after the quad has cleared -- 1.47s observed against a declared 0.97s. Time the fade from where the frame is pure black. Rig: screenshot samples at 0.5 Hz and cannot see a 0.4s fade at all, which is why an earlier burst called this an instant cut. ffmpeg x11grab at 30fps instead; both go in METHOD. |
