port: retract the S00A coverage hole -- it was my control's filter, not the check
Yesterday I reported that a 6 kHz-lowpassed S00A deviated only 1.28 dB, so a transcode that lost its top end would pass the band check, filed it as a coverage hole and sent it to the Decoder, who wrote back that it was the part of my message they would keep. It is wrong. lowpass=f=6000 is SINGLE-POLE, 6 dB/octave -- a mild tilt that leaves most of the octave above 6 kHz in place. I named it 'a transcode that lost its top end' and it did not build that failure. With a real 4-pole brick wall the loss is caught: ADV 6.52 dB at 4.3x, S00A 1.83 dB at 1.2x. Covered, not absent. The instrument took the blame for the control's weakness, one day after I told the Decoder that a control must be a hard negative. The harder rule: a control must CONSTRUCT the failure it is named after. Mine carried the right name over the wrong filter and I read the resulting miss as a property of the check. What survives is weaker and more precise than either version: S00A's margin is 1.2x, which is thin, and the tool now prints a THIN warning below 2x. The margin depends on how much HF the material has, which is a real sensitivity statement. The retraction had to travel fast because the other agent had already adopted the finding. A wrong result the other agent has taken up is more expensive than one they ignored -- an argument for sending corrections at the same priority as findings. Also recorded: they tested 'an asserting step that asserts nothing' against their own tools and both had it, including one written the same day they read my report of the shape. Their statement of it is better than mine -- a check has two failure modes and the loud one hides the quiet one; printing a verdict is not asserting it. And they controlled the exit code in BOTH directions, clean 0, planted revival 1, control passing 0, control deliberately broken 2. My --control flags assert failure-on-perturbation but not that a broken control reports broken, which is the same gap one level up. Next thing to close here.

port: a hard negative found a coverage hole and two defects hiding each other
The Decoder generalised my identity rule back at me -- a positive control that is merely 'high' hides the difference between an exact instrument and a lossy one -- and it landed on the band check I shipped yesterday. Its positive control was 0.29 and 0.66 dB, and small is not zero. Source against itself read 7.656 dB, larger than the number the check calls faithful: bands() applied the fold to one side only, correct for source-versus-transcode and wrong for source-versus-itself. The fold is per-side now and identity reads 0.000 dB exactly. The published 0.66 stands unchanged; what changed is that the instrument is known unbiased rather than assumed to be, and the scale's bottom is anchored. Same rule applied to the port's headline numbers: the image RMSE metric reads 0.0000 for a capture against itself and after a PNG round-trip, so 13.21 is real difference and not pipeline noise. verify-capture now asserts that before printing any row and refuses if it is not exact. Then their refutation attempt on 'band energies need no alignment'. It survives -- 1 s of misalignment costs 0.16 dB -- but 10 s costs 1.00 dB, so the claim is narrowed to robust, not free. Their real point: separation is material-dependent, two unrelated music banks separate by 5.28 dB where an unrelated movie gave me 19-20. A movie is an easy negative, so I built the hard one and it failed. A 6 kHz lowpass is caught on ADV at 4.27 dB, 2.8x, and NOT caught on S00A at 1.28 dB against a 1.5 dB threshold, because S00A's own 6-16 kHz content sits at -67 dB. A transcode that lost its whole top end would pass on S00A. Reported per asset as COVERED / NOT COVERED rather than asserted, and tracked in BLOCKED. Splitting the top band raised ADV from 2.58 to 4.27 dB. That is changing the instrument's resolution so it can see a failure it must see, driven by a control it failed -- the pass threshold is unchanged. Repairing it exposed two defects that had been hiding each other. return 0 was unconditional: making the difference path report-only swallowed the band verdict, so check-all's transcode-bands must-pass step could not fail -- an asserting step that asserts nothing, shipped by me one day after writing up the same shape in someone else's work. And the disqualified difference path was still voting on the exit code, so fixing the return turned the run red for the wrong reason. Neither would have surfaced without a control the tool could fail.

port: the difference path is disqualified, and the identity test is what showed it
Audited my own docs for the Decoder's method-versus-subject error -- a negative
about the instrument written as a negative about the subject. Clean: every
impossibility claim in DECISIONS is already method-scoped ('undecodable WITH
REACH', 'cannot be answered BY LISTENING'), and both live open rows in BLOCKED
read 'not observed' and 'deliberately not inferred'. Nothing to fix, recorded as a
negative.
Then three cheap measurements located the fidelity fault exactly. Identity --
source against a second decode of itself at lag 0 -- subtracts to -inf, so
decode-and-subtract is exact and the pipeline was never the problem. A LOSSLESS
flac of the identical fold reaches only 14.2 dB down, searched exhaustively at
stride 1 over 300 lags, where it must reach about 90. The shipped transcode's 8.73
dB is therefore meaningless.
So the difference path is disqualified rather than inconclusive, and every number
it produced in this thread -- including the 'difference louder than source'
readings I reported twice -- was an artefact of the lag search, not evidence about
a transcode. The tool now refuses on that path and carries its acceptance test in
the code: make lossless-vs-source return >= 60 dB down before believing anything
it says.
The identity test costs one decode and no encoder, and it should have been the
first thing run three iterations ago. Before asking whether an instrument can
measure a difference, ask whether it returns zero for no difference.
Hypotheses ruled out and recorded so nobody re-runs them: drift (offset stable at
about -2465 samples across t=2, 10 and 20 s), container start time (start_time is
exactly 0), the codec being perceptual (the lossless control fails the same way),
and level or content mismatch (bands agree to 0.66 dB).
P4's waveform question is now open with a disqualified instrument -- worse than it
looked yesterday, and better than believing 8.73 dB meant something. The band
check is unaffected and still asserts.

port: a capital letter hid a refuted claim; and band levels answer what alignment could not
Three findings, two of them defects in my own checkers. Changing the KIND of quantity answered the P4 fidelity question on the first attempt. Four attempts at sample-exact difference-signal alignment produced four failures and no verdict -- well past the Decoder's rule that two failed attempts at the same measurement are evidence the quantity is wrong, not the parsing. Band energies need no alignment at all: both transcodes match their sources to 0.66 dB worst-case across four bands, while an unrelated movie lands at 19-20 dB. Two populations an order of magnitude apart, so the 1.5 dB tolerance sits between measured values rather than being picked. Asserting in check-all with the known negative on every run, not behind a flag. It also diagnoses the failure it replaced: matching spectra mean same content at same level, so the difference signal's failure is my alignment, now by evidence rather than assumption. The difference path stays report-only. Band agreement cannot tell a faithful transcode from one that kept the spectrum and mangled the waveform -- weaker than P4 wanted, and what I can support. check-claims held 'no loop-point field has been identified' in its register the whole time and matched case-sensitively, so a capital N at the start of a sentence hid a registered dead claim in BLOCKED.md -- the one document whose job is to say what is still open. The correction had reached authored/audio.json and not the blocked list, which is exactly the failure that file's own why warns about. Matching is case-insensitive now and immediately surfaced five more unmarked sites, including a whole DECISIONS section still describing the refuted state. All six fixed: four tokened, two rewritten with the shipped values. Controlled with a planted capitalised revival. And --control caught its own harness: it perturbed only the first occurrence of an anchor, and the Decoder's delivery heading now appears twice, so the check read the untouched duplicate and passed a wrong contract. A perturbation that does not reach every copy makes a check untestable silently. First time a control has failed because of a change in someone else's document rather than my code. Not accepted from the same message: the (A)-skips-a-movie row is NOT stale. It reads (a) ANSWERED, cites Q9, and points at flow.json's skippable: true. Reported back rather than quietly 'fixed' -- marking a live row stale is the error their own message is about. Every asserting check passes.

port: attempt the P4 fidelity question -- four traps reproduced, no verdict claimed
AUDIO-VERIFICATION.md section 1 calls transcode fidelity the question P4 actually raised, needing neither an engine nor a device, and gives it in four lines of shell. Nothing implemented it: verify-video-audio deliberately declines, saying a difference RMS without alignment is meaningless. So the P4/P7 gate has rested on level and non-silence and the fidelity claim has never been made. tools/port/verify-transcode-fidelity now exists and is committed WITHOUT a verdict, deliberately. Four ways the measurement lies, each reproduced here rather than reasoned about. Indexing with a negative lag wraps to the end of the array in Python, so the difference was the transcode subtracted from an unrelated part of the source -- reported 7 dB LOUDER than the source, the same catastrophic-looking number the doc warns of. My regex for the recorded -af truncated the fold to its FL half, folding the source to a left-only signal: the doc names that trap, I reached it through a parsing bug, and the matrix contains runs of spaces so it cannot be tokenised on whitespace. -ss before -i is a container-level jump and on this WMA Pro source returned 4.6 s for a 4.0 s request while the Ogg side returned 4.0 s, so the windows covered different stretches of the movie, best correlation 0.172 -- this one is NOT in the doc and is indistinguishable from the alignment trap that is. And the single-resolution search returned +2413 against a window of +-2400, its own boundary rather than a peak, the same family as the Decoder's period estimator returning its search floor. Why no verdict: best alignment is corr 0.763 on S00A and 0.075 on ADV, and both still report the difference louder than the source, which cannot be true of two aligned signals at equal level. The remaining fault is on my side. A tool printing 'not faithful' in that state would put a false defect on the exporter. It now distinguishes 'could not align' from 'not faithful', two failures I conflated twice before separating them. Filed for the human as a proposal, not an edit: section 1 should carry the imprecise-seek trap as a fourth entry.

port: make the frame count permanent, then correct what I read from it twice
The Decoder's closing point -- the inference is cheap and the measurement looks expensive right up until someone does it -- is actionable, so the probe I reverted is now permanent. The exporter records each transcode's duration and frame rate in the manifest (probed from the file it wrote, not the source), and every video run prints what it showed against what the media holds. An instrument that has to be added before the question can be asked will not be there the next time somebody reasons instead. Then the instrument corrected me twice more. It is an UPPER BOUND, not a count. It counts engine frames, and the engine renders the UI at its own rate: on a quiet box ADV drew 6480 frames across a 4123-frame video, 44 fps against the media's 30. Above that crossover it constrains nothing, and '157% presented' is the counter used outside its range. The report now says so instead of printing a percentage. So 'the player skips, heavily' is not supported. At 8.3 engine fps under contention S00A could not have shown more than 28% -- a valid bound under contention and nothing more. Quiet, the bound is 88-90%, permitting anything from no drops to a tenth. And the 720p-versus-432p contrast is refuted -- the finding I sent them twice. I reported ADV +6.7% against S00A -0.5% and built 'heavy decode falls behind, light keeps up' on it. Quiet, both run +6.7...+6.9%. The -0.5% was a contended run in which the player dropped frames to hold schedule. I was measuring which run happened to share the box and reading it as a property of the resolution. What survives is sturdier than either: playback runs +6.7%...+6.9% long on this container, five runs, both videos, quiet, resolution-independent. Three corrections in three iterations, all mine, all the same shape: argued from an absence; measured and over-read; then found the measurement was taken under a confound I introduced myself by running the suite alongside it. Their rule needs a companion -- ask what the quantity can be skipped by, and ask what else was running.

port: I measured my own claim and it is wrong -- the player skips, heavily
I told the Decoder that a player running long decoded everything, so my video spans were time-to-consume measurements. They granted it and added the refinement I had not claimed: running long proves the player did not skip ENOUGH to stay on schedule, not that it skipped nothing. That is testable, because a video player cannot present more video frames than the engine draws. Engine.get_frames_drawn() across each playback: S00A drew 775 frames in 93.33 s, 8.3 fps, 28% of the 2813 frames in the media; ADV drew 1941 in 140.77 s, 13.8 fps, 47% of 4123. Both skip most of their frames, and S00A kept real time BECAUSE it dropped roughly three frames in four -- the exact mechanism I claimed was absent. The sentence was not unproven, it was false, and the probe that refutes it is four lines long and could have been written the day I wrote the claim. The probe's honest limit, stated because it cuts the other way: it counts PRESENTED frames, not decoded ones. Theora is inter-frame predicted, so a decoder generally must decode frames it never displays. This refutes 'presented every frame' and leaves 'decoded every frame' unmeasured, and I have no instrument for the second. Their read_offset counter is a consumption counter precisely because it cannot have that gap. And the number I sent them twice is a spread. Three ADV runs: 146.42, 146.60, 140.77 s, giving +6.5%, +6.7%, +2.4%. I quoted +6.7% as the measurement; it is the top of a range whose spread is nearly as large as the effect on the third run, and the runs differed in what else the port was doing. Reported as +2.4%...+6.7%, n=3, load-dependent, from here. What survives is the qualitative result they cared about: heavy decode falls behind the container clock and light decode does not, demonstrated in one box -- now correctly stated as a lower bound on a deficit measured under skipping. The general form, third time in this project: I argued from an absence -- no overrun would be visible if frames were dropped -- instead of measuring directly. The direct measurement cost four lines. An argument that a mechanism is absent is not a measurement that it is absent, and I had just told the Decoder that being right by luck is not evidence. Also recorded: their sweep for stale HANDOFF sections is a negative, 7 candidates and 0 real, because in that corpus a red heading marks a correction being delivered far more often than a section overtaken. Neither of us should build it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01N7FiFFFwbvG2uxdcEh8HyF |

port: a leak that was not mine, a second narrow anchor, and a result recovered
Three findings, one of them a withdrawal of my own fix. The ObjectDB leak line on every run is engine-side. The leaked objects are the Ogg streams and playbacks of exactly the cues that sounded, which reads as MenuAudio holding references past teardown. It does not: releasing every reference the port owns -- stop each player, null every stream, clear _players, clear cues/beds/voices -- moved the count not at all, 8 before and 8 after, with a debug print confirming _exit_tree runs. The cleanup is REVERTED rather than kept, because code that changes nothing under a comment claiming to fix a leak is worse than none: the next reader sees it handled and stops looking. Filed as a negative result so nobody re-investigates. check_focus_persists gets a SECOND NARROW ANCHOR, repairing a weakness I recorded last iteration and did not act on. It anchored on the heading -- the conclusion -- so when the Decoder corrected the run's item names it sailed past, surviving by luck rather than design. It now also rests on the evidence, the ring at y 384.0 before the round trip and 385.5 after, which is the geometry-free equality the conclusion stands on. The two anchors are checked AGAINST EACH OTHER: if one matches and the other does not it reports ANCHOR SPLIT. The second anchor has its own known negative, perturbing only the evidence line -- without that it would be decorative and the check would still rest on the conclusion alone. And their skippability rule recovers a result I had over-withdrawn. Frames can be skipped, bytes consumed cannot; that is why my withdrawal reaches my test and not their read-offset one. Applied backwards: the OVERRUN IS the evidence nothing was skipped. A player that drops frames finishes on schedule; mine took 146.6 s for 137.44 s of media, so ADV +6.7% and S00A -0.5% are time-to-consume measurements after all. The withdrawal stands for the pacing-audit use; the load-starvation result is recovered. Standing caveat recorded: every timing this port publishes is frame-derived, and the only reason those seconds mean anything is that this player demonstrably does not skip -- an empirical property, not a guarantee, and nothing checks it. Reported: the 'do not hardcode the menu's initial focus' HANDOFF section still reads as live while two later sections have overtaken both its claims. Every asserting check passes; 14 controls fire.

port: my media-versus-wall-clock method cannot audit container pacing
The Decoder proposed borrowing it to settle their 27.6 fps confound. It does not work, and the reason matters more than the result. Three S00A replicates, whose 93.78 s is fixed by its own sample rate: -0.44%, -0.51%, -0.50%. Tight, reproducible, and unable to answer the question it was asked. The video player is driven by the container clock -- it picks frames from elapsed time as that clock reports it -- so a uniformly slow clock would present fewer frames per real second and still finish in exactly 93.78 s of container time. A perfect match, produced by the failure it was meant to detect. Every timer inside shares that clock, the shell's date included. My earlier entry conflated two uses. 'Compare through media length, not wall clock' is sound as a COMMON UNIT between their numbers and mine, because media length is container-independent. It is not an AUDIT of pacing. Corrected here and in BLOCKED rather than in place. What the contrast does establish favours their doubt. Same container, same clock, same player: ADV at 1280x720 runs +6.7% over its media, S00A at 768x432 runs -0.5%. Load-dependent starvation is demonstrated positively, not inferred, and Xenia is far heavier than 720p Theora while their frame counts are taken per container-second -- the exact axis this acts on. What would settle theirs is a clock the guest does not control: frames presented per audio sample consumed, since audio hardware consumes at a fixed rate. Offered as a route, theirs to say whether Xenia exposes it. Their addendum to global-versus-narrow is written into contract-check's header: they did not loosen an instrument gradually, they swapped it wholesale the moment it failed and the swap felt like rigour. So when an ANCHOR LOST comes, add a second narrow anchor rather than one looser one.

port: running it as a player finds two defects reading it did not
--boot --script= parsed, was stored, and did nothing. The script only starts at _menu_enter, and a --boot run without --play never enters a menu -- it holds on the title and quits. The run completed, exit 0, no menu line, no press: a clean result to a question never asked. This file already warns about that exact shape 600 lines above the bug, where --capture used to photograph the first frame of a scripted run. The warning was written, kept, and did not stop the same class recurring in the neighbouring flag. Now push_errors and exits 2, naming both working forms, refusing rather than implying --play since the two runs differ by 157 s of intro. Verified: --boot --play --script walks power-on through splashes, ADV, title, (A), main menu, down, (A). A comment above audio.play_bed described the port as CHOOSING the menu track, which HANDOFF Q10 refuted a week ago -- BGM_103 is measured on three independent legs and audio.json says so. Third instance of the drifted-comment trap. The dead phrase is now a check-claims register row, controlled: a planted revival fails and removing it passes. And the boot's wall-clock seconds are a property of this container. ADV takes 146.6 s of wall clock for 137.44 s of media, +6.7%, while S00A runs real time at -0.4%. Not a post-roll and not a general deficit: ADV is 1280x720 and S00A is 768x432, this box has no GPU, and 720p Theora decodes below real time here. The transcode is faithful against a 137.71 s source and the exporter does not rescale. P3/P7 artifacts quote seconds containing that deficit -- reproducible here, not a statement about the port or the game. Comparisons with the Decoder's measurements must go through media length, not wall clock; they carry an explicit emulator pacing factor for the same reason and I had been quoting mine as exact. Their negative result on LOAD GAME, TUTORIAL and OPTIONS leaves guard_focus_scope right to count them UNMEASURED rather than 'resets'. The transferable part is their instrument story: a narrow calibrated reader failed, so they generalised to a whole-frame comparison, which died the moment a crash dialog overlaid the frame while the narrow reader kept working. contract-check is deliberately narrow, individually anchored checks for the same reason, and the temptation after an ANCHOR LOST will be to loosen the matching -- trading a failure I can see for one I cannot. Every asserting check passes. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01N7FiFFFwbvG2uxdcEh8HyF |

port: EXTRAS resets, measured -- and being right by luck is not evidence
Ring at 347.5 on entry (MISSION SELECT), 427.5 after one delivery-confirmed DOWN, 347.5 on re-entry with the frame 0.0% different from first entry, screen confirmed by eye because an earlier run was fooled about which screen it was on. Two things settle here. The caveat on extras/initial_focus comes off: MISSION SELECT is a genuine initial focus, because a screen that RESETS cannot have a single-entry reading that is measuring history -- that objection was live only while persistence here was unknown. And focus_persists: false for extras is now written explicitly with kind: measured. Nothing changes at runtime, since the port already defaulted to false; the point is that an absent key and a measured false behave identically and mean opposite things -- 'nobody looked' versus 'the game was watched doing it' -- and only the second is visible to audit-kinds. It does not vindicate how it got there and is not recorded as if it did. For one iteration contract-check ASSERTED extras non-persistence with nothing behind it, the Decoder flagged it, and the measurement then agreed. Their separation is sharper than my own account was: declining to generalise the memory was correct, on the evidence then and on measurement now, since the two screens genuinely disagree -- but encoding 'not measured here' as a positive assertion of the negative was a different move that happened to land. Being right by luck does not retroactively make it evidence. The check is rewritten to rest on the measurement rather than left in place looking vindicated. guard_focus_scope no longer polices 'only main_menu': there is no menu-wide rule to state, since two measured screens disagree. It now states both measured values and counts the screens that say nothing, printing UNMEASURED, not 'resets'. Untested and not built on: OPTIONS, LOAD GAME, TUTORIAL. And nobody can separate 'resets to MISSION SELECT' from 'resets to the top item' -- they coincide, since ptbtn11 is both. The port's value is right under either reading and the reason is not established, which matters the day a screen is authored whose opening item is not its first. 16 kind labels audited clean, 14 controls firing, every asserting check passes. The P5 walk artifact now matches a measurement on both halves rather than one measurement and one default.

port: an authored value becomes measured, and a difference-only check gets an origin
The Decoder corrected their own focus delivery: the persistence run's item names were two positions out, from a reader using design-space rows against captures carrying Xenia's chrome and a 1.060 scale. Two things follow. initial_focus_kind moves from authored to measured. NEW GAME on a fresh boot, 2/2 fresh boots, both the first menu entry. The value did not change; its standing did, and the upgrade is not because the measurement agrees with me -- they had said my agreeing with their records was no evidence, which was correct, and this is a direct reading independent of the reasoning that chose NEW GAME here. "First entry" is load-bearing: since the menu remembers its cursor, a reading taken later measures history, which is the objection that voided the earlier TUTORIAL-versus-NEW-GAME disagreement. The superseded reasoning is kept under (was) lines -- the field existing and being labelled honestly is what made arriving at a measurement a label change rather than an archaeology problem, the third time that has paid off after loop_start_s and the +0x08 read. My check_focus_persists anchor survived a correction it should not have been able to detect. It anchors on the heading, the conclusion, not on the item names. That is lucky rather than designed: the conclusion is geometry-free -- ring at y 384.0 before the round trip and 385.5 after, an equality immune to a constant offset -- while the names were not. The check would not have caught the label error, and nothing in it distinguishes anchored-on-a-robust-claim from anchored-above-the- part-that-was-wrong. Their generalisation: a control that only checks differences is blind to the origin. check_splash_dwell is that shape -- it compares the widest gap between keyframe times, and a reader with every time shifted by a constant passes. Added check_splash_times, asserting the absolute list the contract prints. Origin and difference now fail independently. Writing that control reproduced the error one level down: its perturbation literal was written from memory of the prose, with a space where the document has a newline, so it reported its own anchor gone. A control written from a memory of the source rather than from the source is the class of error these checks exist to catch. Thirteen controls, all firing. Q2 closed: fixed same day, and the row was worse than I reported -- the splashes were also mis-paired as 10/11, one half each of two different pairs. EXTRAS remains unmeasured; the run meant to settle it navigated to OPTIONS believing it was EXTRAS. Every asserting check passes.

port: audit every kind label, and seven rested on a neighbour's argument
tools/port/audit-kinds reports what each in authored/ rests on. Nothing had ever checked them, which is the point -- the disciplines that fail this way are the ones that never visibly failed. Seven of fifteen labels, every goto_name_kind, had no of their own. Four scored ok on the first run because the audit fell back to the parent's , which argues the DESTINATION while the label is about where the NAME came from. That is the same error I was corrected for the previous iteration, one level down: crediting a claim with evidence that does not bear on it. Borrowed evidence is now its own outcome, and all seven carry a why citing HANDOFF Q4's own words and stating that the port never branches on the field. The audit refuted itself twice first. It counted only paths, shas and filenames as citations, so HANDOFF Q1 and PORT-MISSION section 7 read as citing nothing -- four false positives, and an audit that invents defects is worse than none because its false positives are indistinguishable from its true ones until each is opened. It also resolved paths against committed refs only, failing on a citation to the tool being written. Both fixed. It still cannot read a cited page to confirm it says what the why claims, and prints that every run. MEASURED and measured both existed; a consumer comparing == measured misses the other, and a label that fails to match reads as ABSENT rather than wrong. Normalised. Refutation attempt on HANDOFF Q2's map of GP_TITLE. The headline survives and is exactly right: 4 UI states + 2 loading variants + 2 boot splashes = 8 states shipped twice = the 16 entries the archive holds, confirmed against my export's entry map. But the row enumerates six of those eight -- entries 10, 11, 13 and 14, publisher_logo and developer_logos, appear nowhere in it. A reader counting Q2 gets twelve, and this is the row already corrected once for an ordinal-versus- entry error, which is the mistake four unlisted entries feed. The port is unaffected; both splashes are exported, named and verified at RMSE 2.17 and 3.05. Every asserting check passes, audit-kinds included.

port: correct a check that asserted an absence of measurement as a finding
The pair I shipped this iteration -- focus_persists on for main_menu, off everywhere else -- reported both halves as agreement with the contract. Nothing measured that extras does not persist. The corpus has EXTRAS' opening item from one entry and (B) restoring the PARENT's focus 4/4; neither says what a submenu's own cursor does on re-entry. Caught by the Decoder. It is the mirror of the trap it was written to avoid. I refused to let a derived menu-wide rule overwrite a measured value, then let 'not measured here' become a positive assertion of the negative. Both treat a gap in the corpus as if it carried information and differ only in which direction they fill it. And the failure mode was the bad one: if the game does persist EXTRAS, the check holds the port to the wrong behaviour and passes while doing it. check_focus_persists now asserts only the measured half. The scope became a separate guard with its own outcome word -- 'only main_menu, AUTHORED DEFAULT, unmeasured elsewhere' -- which still fails if widened, since that should be a deliberate edit, but can no longer be read as the game being known to reset. focus_persists_why records the correction rather than being rewritten. It also weakens a label. EXTRAS' initial_focus is marked measured and was taken on a single entry; now that the main menu is known to remember its cursor, a one-entry reading of any screen may be measuring history rather than what the screen opens on -- the same objection that reframed the TUTORIAL/NEW GAME disagreement. The observation stands, its reading as an initial focus does not. Caveat attached, kind left as measured with a note that it changes if EXTRAS turns out to persist. Not building on the non-persistence half until their EXTRAS re-entry run returns.

port: the main menu remembers its cursor -- a measured P5 defect, fixed and scoped
Measured by the Decoder today: (B) from the menu to the title and (A) back returns to the item you left, not to a default; their control passed first, two delivery-confirmed DOWNs moving the cursor exactly two items before the round trip. The port reset to initial_focus on every entry, so a player who moved to EXTRAS, pressed (B) then (A) landed back on NEW GAME. MenuFlow.enter() now consults opening_focus(), and a new set_focus() writes the memory. set_focus() exists because two call sites set focus -- a cursor move and (B)'s restore -- and a memory updated at only one of them is right until the player uses the other. focus_persists is true on main_menu and nowhere else, and the scope is the authored part. wrap generalised because it was measured on two screens; this was measured on one. Here that is stronger than a preference: extras opens on MISSION SELECT as a MEASURED initial focus, so a menu-wide memory would have silently replaced a measured value with a derived one. Both halves are in one artifact, because a one-sided test passes a port that quietly generalised: the menu returns to ptbtn05 after the round trip, and extras opens on ptbtn11 both times despite being left on ptbtn12. contract-check asserts the pair -- on where measured, off elsewhere -- and fails its known negative. Eleven checks. Not assumed: whether the memory survives a reboot, or whether any other screen has it. Their reach is one boot, one round trip, one direction. The finding also reframes this morning's initial-focus warning without settling it -- if focus persists, a reading not taken on a fresh boot's first entry is measuring history. NEW GAME stays authored, on its own reasoning. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01N7FiFFFwbvG2uxdcEh8HyF |

port: take formats-pin-2026-08-30b and stop owning the +0x08 read
The tag was cut within the iteration, so screen.rs now calls ui_layout::loop_length_units and its local RATC guard and byte read are deleted. One line, as predicted -- and the doc comment promising that deletion is the only reason a temporary reading did not quietly become permanent. A pin bump moves the whole crate, not one function, and this pin is recorded load-bearing, so both commits between the tags were read before taking it: |

port: check the walk as well as the contract, and a defect I nearly filed off a debug pin
docs/game/navigation.md is a second document unreachable from main, and
authored/flow.json is its executable form -- nothing in the port fails when a
label drifts from it. Three more checks in contract-check, anchored on the walk's
own text: the five main-menu labels in order, EXTRAS' three items, the cursor
wrap. Ten checks now, ten known negatives, all passing.
The manual audit behind them found nothing else: initial focus is already
kind:authored citing Q5's instability, left_right is an explicit no-op,
auto_repeat is measured, unexported destinations are marked blocked with reasons.
Refutation target: the walk's claim that the ring is the ONLY thing moving on the
settled menu. Cannot be tested against the game from here, but can be tested
against my renderer, which is the direction that matters. Five renders across a
full ring cycle: 1428 of 921600 pixels vary, 0.155 %, one 46x44 cluster beside
the focused item. The port animates one ring, not five -- worth checking, since
all five ptbtn01f..05f declare the same 120-unit cycle and a renderer running all
of them would look identical until you diffed frames.
Then I nearly filed a serious P5 defect against myself: sweeping --leaf-time with
the ring pinned moves 10.4 % of the frame, full-screen. It is not a defect. That
pin addresses the build-in -- ptloop01 runs t=0..600, ptloop02 t=0..720 -- and at
settle both park off-screen at x=1521 and x=-839, with loop_leaf_on_screens
scoped to the title alone. The general form: a pin that can address states the
screen never occupies will manufacture defects on demand, which inverts what the
three pins are for.
The +0x08 ask came back answered and is not consumable. ui_layout::loop_length_units

port: Q10 correction does not reach me; the register's cost is per-mention
Their stale Q10 row does not touch my tree: stems_why already reads 'a bank is exactly TWO waves of identical duration', the corrected understanding, and the three-sub-waves discrepancy is recorded here as refuted. stems: sum unchanged. Nor do I cite their coherence discriminator, which they flagged because its own control showed L-vs-R within one wave reading 0.22-0.50, so its premise fails in this material. Adopted their paraphrase resolution: the register entry is the verbatim home of a dead phrase and prose paraphrases freely, since they are different documents. That resolves the prose half but not my hook, and I wrote the limit into the tool -- it detects whether a section contains a registered phrase, so it will always over-report on well-written corrections, mixing 'never registered' with 'registered and paraphrased'. A prompt to check, never a defect count. Fourth instance of the recursive cost, incurred while documenting it: writing that comment quoted a registered phrase and check-claims failed, as did the previous entry explaining that the corrected heading no longer contains it. Both marked. So the cost is not per-correction but per-MENTION, and mentions multiply once the register becomes a subject. Four instances, each inside text about the mechanism.

port: full regression passes; the phase term moved two published rows
Ran the suite after a session of edits to boot.gd, screen_view.gd, four tools and two authored files. Every asserting check passes, and verify-screen's two DIFFERS are the named pair with per-screen reasons. Two oracle rows moved: title_plate 12.83/0.00% to 13.04/0.09%, title_band 15.31/0.35% to 12.86/0.00%. Opposite directions, which is a phase change rather than a regression, and the cause is mine -- adding --leaf-time=0 to verify-capture's render sites pinned the sweeps while the captures froze them wherever the shutter caught them. That makes the capture-phase term concrete: I documented +/-5.56 for title from a sweep, and here it moved two published rows from a one-line harness change. It also touches a number I published -- the boot-end-frame 0.00% was measured before the pin, and the equivalent row now reads 0.09%. Both inside the term, and the right reading is that neither is 'the' number. Also narrowed the withdrawal-time hook. Its regex matched headings ABOUT corrections rather than headings making them, so 33 was a measurement of the regex; narrowed to a leading WITHDRAWN/CORRECTION/Refuted, it gives 10, all genuine retractions. Residual limit named: several of the ten are flagged because the registered phrase does not appear in that section -- the corrected JP heading reads 'does NOT go against the port', which does not contain 'goes against the port'. The register wants the claim quoted; a good correction paraphrases it away.

port: their 0.32 retraction dissolves a tension I recorded -- both halves gone
They retracted RMSE 0.32 as a noise floor: their plate-pulse gate phase-locks the shutter to the title animation, so it measures their trigger's repeatability rather than the game, and 11.9 is the replacement title-capture figure. Checked my tree. Two hits: one is my own unrelated splash ink measurement that happens to read 0.32, the other is a genuine citation. My entry used their 0.32 as evidence the sweep is absent on the JP title, creating a tension with my EN curve that I recorded as unadjudicable. Both halves are now gone. Half one was settled by their draw-stream run -- the leaves are drawn and free-run, so present was right. Half two is retracted at source: two captures at the same animation phase show identical content in the sweep band whether or not the sweep is drawn, so the figure never argued absent. I built a tension I could not adjudicate out of a number that carried no information about the question. It looked like a conflict between two measurements; it was one measurement and one artefact of a trigger.

port: localise the off-edge splash residual -- 98% of the area is exact
Tested the last signature on the open residual: is it positional? A sub-pixel or resampling difference makes the residual track local gradient. Rule stated first, r > 0.5. Got +0.109 and +0.307, and the brightness control settles it -- on developer_logos brightness correlates more strongly (+0.471) than gradient, so the gradient signal is not distinguishable from 'content is where things happen'. Not positional. The brightness correlation pointed somewhere better. Signed residual by capture brightness, off-edge: 843025 of 857573 pixels on publisher_logo and 812111 of 850869 on developer_logos sit in the 0-15 band with a residual of -0.00. So 98% of the off-edge area is exact, and the entire 0.82-1.42 RMSE comes from the ~2% of pixels that are lit. Within those the sign is inconsistent across bands and across screens -- publisher +1.68, -1.09, -2.48, +0.45 against developer +2.19, +0.74, -1.57, -0.96 -- so not a global gain and not a global curve, consistent with a per-level LUT fitted on its own pixels improving them by only 1.6%. Three mechanisms now ruled out with evidence: global tone, texture decode, positional. Still no mechanism, and naming what it is not four times is not finding what it is.

port: run their absence shape on my citations -- five stale paths, and a wording gap in my P0 closure
Their finding was about their own audit: evidence exists in three forms and their check looked for one, so '48 citations, 0 missing' was a statement about the data-file form -- reported in the wording rather than the scope. The analogue: do my own citations resolve? 32 paths cited in DECISIONS.md, 12 do not. Inspected before publishing -- fifth instance of that habit here -- and most are relative fragments, the Decoder's branch files, a historical absolute path, and a hypothetical modding example. Genuine: five stale citations from the docs/ -> docs/port/ reorganisation, rewritten. And one reached a claim I published last iteration. P0's gate says the export 'validates against FORMAT.md'; my closure reported the validator saying '16 screens validate against sylpheed.screen/3'. Different words, and I certified the gate on one while quoting the other -- their exact failure, in a gate closure published as verified. Checked rather than assumed: docs/port/FORMAT.md is 405 lines and contains format: sylpheed.screen/3 as the specification, so the schema the validator enforces is the one FORMAT.md defines and the closure stands. But it stood on an unstated identity, and had FORMAT.md described a superseded format nothing in the check would have said so, because the validator never mentions FORMAT.md. Verifying in the tool's vocabulary and certifying in the gate's is a substitution nobody performs explicitly.

port: run their sufficiency check on authored/ -- clean, after nearly reporting 35 false positives
Their audit found 48 citations resolving and 0 missing, with the caveat that it cannot see data a page should have cited and did not. The port-side analogue: my earlier audit checked what a MEASURED stamp cited and could not see an authored value carrying no why at all, which passes by being absent. First pass flagged 35 of 131 values as bare. Every inspected sample was a false positive: ptbtn01's label and goto sit in an object carrying five *_why siblings plus a blocked explanation, and /voice/stream_weights/.../position is covered by a _ key one level above, which the check only looked for in the same object. Ancestor-aware, the real number is 126 values and 0 uncovered -- every authored scalar has a why, _ or *_why in its own object or an ancestor. 35 was the instrument's resolution, not a finding. Third instance in one exchange after their 9 raw hits going to 2 real and my 33 hook candidates: a first count from a new detector is a measurement of the detector. Their caveat transfers unchanged and is stated rather than glossed: this tests that a why exists in scope, not that it explains that value. A parent _ covering twenty values may say nothing about any one.

port: record the P0 gate, verified -- and name the gap it belongs to
They were right that the P0/P2/P5 gap matters more than the P2 fix. P0 is the one of the three I can close alone: its gate names no human and no emulator. Verified both halves. export/screens/title/main_menu.json exists at 51011 bytes, the validator reports 16 screens validating against sylpheed.screen/3 with that file among them, and all 20 sprites it references open as PNG with 0 missing and 0 unreadable. P0's gate is met on an artifact and now written down; it had been met for a long time and only the record was missing. That is the argued-versus-indexed split one level up. The refutation register taught it about deaths -- the page is where a refutation is argued, the index is where it is found. Here the milestone was completed and never indexed: the work existed, the artifact existed, the gate record did not. Remaining: P2 verified and recorded last iteration; P5 is 'a human clicks through it', which I cannot self-certify and will not try. Converting it into something I can check would be rewriting the gate to fit the checker, which is the mission's own warning about gating on 'it compiles' in a more flattering costume.

port: apply 'a correction is a new claim' to my own most recent correction
Their rule, from replacing a stale status with an unchecked one in the edit criticising unchecked status: a correction is a new claim and needs the same check as the claim it replaces. I made that shape of edit last iteration. The blocker halves were checked -- I confirmed Q1 and Q10 read 'answered' in HANDOFF before writing it. The gate half was not: my correction asserts 'Gate met' for P2 and there is no P2 gate record in DECISIONS.md at all. Written from confidence. Resolved by measuring rather than withdrawing. ptbtn01 declares y 142 -> 162 across t=28..34; rendering main_menu at both gives a changed region 307x215 at (542,162), x and final y matching the declared button exactly, max difference 159. The port does slide the buttons in, so P2's gate is met -- now on evidence. Being right is the dangerous part: an unchecked assertion that happens to be true does not announce itself, and correct-by-luck is indistinguishable from correct-by-checking in the text. The check also turned up that P0, P2 and P5 have no gate record while P1, P3, P4, P6 and P7 do. P2 is now verified here; P0 and P5 remain unrecorded and unverified, and P5's gate is 'a human clicks through it', which I cannot self-certify. Their boundary holds: this correction would have passed my own withdrawal-time hook cleanly. Neither mechanism tests whether a correction is true.

port: build the withdrawal-time hook, and violate the rule it enforces while writing it
They ended with 'it needs a hook at withdrawal time, not a sweep'. Expressible, because a correction here has a shape: a heading carrying WITHDRAWN / CORRECTION / refuted. A correction section containing no registered phrase is a death argued and never indexed. check-claims now reports them, and the first run names more than my 'four of eight' -- the shortfall runs back through earlier work. Reported, not asserted, deliberately: not every correction retires a claim, and forcing rows for those would push rows in to silence the check. Two failures while building it. The first version pasted the register rows into its own heredoc, so every registered phrase became an unmarked quotation and check-claims flagged its own source -- a tool violating the rule it enforces by being written. Fixed by passing the register through the environment. And writing up the previous catch re-introduced three unmarked quotations: describing a refuted claim quotes it, so every correction is a new occurrence needing the token. The cost is recursive, which the header implies but does not say out loud. What the hook does not do: it fires when a correction is written, so it closes the gap between arguing and indexing, not between believing and arguing. Nothing here would have caught me copying their 'structural' claim into my record.

port: their REFUTED gap, in a register I had and fed nothing
Their finding: eight claims died this session and none reached REFUTED.md, the file their brief says to grep before proposing anything. The pages are where a refutation is argued; the index is where it is found. Mine is the same gap and worse in one respect. tools/port/check-claims is a register that FAILS the run if a refuted claim is quoted without its [refuted] token, and it is in check-all -- so an entry enforces rather than merely publishes. It held 7 rows, all from earlier work, and I added none while withdrawing about 8 claims this session. Registered four. The checker immediately flagged three still asserted unmarked, and every one was inside a correction I had written myself -- the headings-audit table rows explaining the withdrawals, and the EXTRAS withdrawal block. That is the token doing what phrasing cannot: all three read as corrections to a human and the marker fired anyway, because it tests for a token an author places rather than for language that sounds retracted. Marked; the register now passes. Scope: four of roughly eight registered. Not registered -- the compactness precondition, the half-rate defect, 'the eras render identically', and my 16/16/18 rule -- each argued in its own correction and findable by nobody. Stopped at four because each row costs marking every existing quotation by hand. And nothing mechanically checks that a future withdrawal reaches the register.

port: finish the required-reading audit -- MODDING clean and checker-backed
Finished the second half rather than leaving it named. MODDING.md carries no status markers at all, so nothing of the stale-blocker shape. But their finding was about claims, not markers: it states five rules, and tools/port/check-modding asserts all five by name, one section each, and passes in check-all. Those claims are mechanically verified on every suite run rather than merely unstaled. Of the five documents the brief names, three are mine: BLOCKED.md (five rows struck earlier), PORT-MISSION.md (two stale blockers corrected), MODDING.md (clean, checker-backed). PROTOCOL.md and HANDOFF.md are not mine to correct, and HANDOFF as I read it is the stale main copy, which is its own recorded problem. Also checks their 'a ranked list always has a winner' against my own matching. My GP_TUTORIAL identification ran the control first -- my own title capture over seven builds with a known answer, picking build 4 at +0.2792 -- and the submenu then scored +0.4962, above the calibrated true-match score rather than merely top of a list.

port: PORT-MISSION.md had two stale blockers, in the file I read every iteration
Their finding was that MISSION.md carried three stale headings while they had audited everything else. The diagnosis transfers: a document read only for instructions is never read for review, and the more central it is the more often it is consulted and the less often checked. The brief names five documents to read every iteration. I had audited BLOCKED.md and never PORT-MISSION.md or MODDING.md. Two stale blockers in the table I am told to consult to find the lowest unfinished milestone: P2 'Blocked on HANDOFF Q1 -- do not invent it' when Q1 is answered (ramp linear, 2 units/frame, 1 unit = 1/60 s) and P2 shipped long ago; P6 'Looping is blocked on HANDOFF Q10' when Q10 is answered and the P6 gate is recorded verified. Worse than a stale heading in a record: a stale INSTRUCTION in a document whose purpose is instruction, the class we ranked highest. Scope: PROTOCOL says only the human changes a mission, so I corrected the factual status clause and nothing else. Gates, requirements and asks untouched, original struck through rather than deleted so the change is visible and reversible. If a human reads this as a mission change rather than maintenance, revert the two table cells. MODDING.md is still unaudited and is named as such rather than quietly skipped.

port: check their incoming-primitive observation -- counter-example stands, and it cannot explain the intra-archive spread
They offered, with its counter-example attached, that the incoming screen's
full-screen primitive is [255] where the gap is 0 and [127] where it is 1, failing
on menu -> EXTRAS which declares a black backdrop and gives 1.
My first check got it wrong and would have dissolved their counter-example: I took
the FIRST full-screen primitive in element order and reported extras arriving at
alpha 64. extras has two such primitives; I read one and called it the screen's.
Corrected, all three GP_TITLE screens are identical in this respect -- pteff00 at
255 painting last, pteff02 at 64 -- so every one opens with an opaque black quad
on top clearing over 12-16 units, extras does arrive at 255, and their
counter-example stands.
The sharpening: within GP_TITLE this quantity is CONSTANT, so it cannot explain
any variation among the four intra-archive pairs. It could only separate GP_TITLE
screens from outside ones, which is much narrower than 'begins from black implies
no blank frame' and is already contradicted by menu->EXTRAS 1 against
menu->other-2 0, both arriving at an opaque incoming.
Their new pair kills the origin story from my side too: the menu gives {0,1,1,0}
across four destinations, both extremes from one origin.

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

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

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

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

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

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

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

port: close their XPR lead, and find their class in the lane I called clean
They flagged five XPR_* texture toggles as relevant since I consume textures, and my off-edge splash residual -- non-tonal, ~0.5 RMSE above quantisation, no candidate -- has the shape a subtle decode difference would produce. Closed: the toggles live in texture.rs::decode_surface, shared by from_xpr2 and cube_faces_from_xpr2, and my exporter calls neither -- sprites come from t8ad::parse. t8ad.rs reads no environment variables in its 202 lines, so the sprite path has no hidden freedom either. The candidate is eliminated with no replacement. Enumerating what my exporter reaches turned up SYLPHEED_KF_TIME_SHIFT, which they reported as absent from crates/. True on their branch, false on mine: my ui_layout.rs is the stale era and the knob is live at line 497. The pinned tag has 0 occurrences (2 of LEGACY) so export/ cannot be perturbed, but verify-screen builds its reference from the workspace, which can. Tested both directions: with the knob the reference reports rest t=12, the corrected reading, and the era guard passes; without it, t=70 and the guard refuses. So the knob is the working remedy that makes a workspace-built reference usable, and it appeared in no tool, help text or instruction in my tree -- their exact class, in the lane I had just told them was clean. The refusal message now carries the remedy. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01N7FiFFFwbvG2uxdcEh8HyF |

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

port: sweep instructions above descriptions -- the silent class is clean, two loud hits
Their sharpening: a stale instruction manufactures a false confirmation, strictly worse than a stale description that merely misleads. Applied to my instruction surface, the documented invocations in tool and script headers. All fifteen distinct flags across those examples are parsed, so nothing in my headers can produce their failure mode by being inert. But 'parsed' is a proxy and its gap is known -- --shots parses and does nothing on the --boot path -- so I ran two documented examples end to end rather than trusting the grep, and both produce a 1280x720 frame. Two hits, both loud rather than silent: 11 references to tools/verify-capture and tools/verify-screen, paths that do not exist since the tools are under tools/port/ (fixed in 4 files); and check-all claiming eleven tools where there are fourteen (now states both so the sentence dates itself). The distinction worth recording: mine fail loudly, theirs failed silently. A wrong path announces itself; an inert environment variable returns a clean wrong result. Both are stale instructions and only one manufactures evidence. Honest limit: I tested the flag surface plus two examples end to end, not all thirteen documented invocations -- the --boot ones take 156 s each. That is a judgement about cost, not a claim of coverage. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01N7FiFFFwbvG2uxdcEh8HyF |

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

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

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

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

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

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

port: audit the --black premise -- declared on 12 screens, assumed on 4, all composited
Their finding that screen render --black's premise is declared on the splash builds is checkable across my whole export, and verify-screen passes --black to all sixteen screens on that premise. Audited by asking whether a screen declares a full-screen untextured primitive at t=0 with fade_argb 0xff000000. Twelve do -- pteff00 on both titles, both menus and both extras, palogo_eff0 on all four splashes, pgloading_eff00 on build_12/15. Four do not: press_start, press_start_jp, build_00, build_01. All four exceptions are composited rather than standalone. press_start is one element, the plate, whose own name_why records it is composited over the title. build_00/build_01 carry the pgloading_* set without the pgloading_eff00 backdrop that build_12/15 declare. Harmless where used: verify-screen gives --black to both renderers so the assumption cancels in a consistency check, and verify-capture already scores the plate over the title rather than on black. The exposure was real and the tooling had already routed around it, which could only be established by looking. The rule that falls out: a declared opaque-black backdrop distinguishes a standalone screen from a composited one, derivable from the file rather than from a name. Recorded as a rule with its evidence -- sufficient as observed, not proven necessary, on four exceptions.

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