55d30209d9 port: the counter-example I kept asking for was in a file I wrote
For several iterations I said the MISSION-SELECT-versus-top-item ambiguity needed
a screen whose opening item is not its first, and that none was known. The Decoder
found one and reported it had been sitting unconnected in their corpus.

It is in mine too, and I authored it. authored/flow.json under
main_menu/buttons/ptbtn01 has read since 1defbe0 on 2026-08-29: 'MEASURED
destination (EASY/NORMAL/HARD/BACK, opening on NORMAL, then SELECT DATA)'.
DIFFICULTY opens on the second of four. So 'a screen opens on its first item' is
refuted as a general description of this game, and on EXTRAS, TUTORIAL and OPTIONS
the named item and the top item coincide by accident.

Worse than an index failing to amplify: my extras/initial_focus_why framed the
ambiguity as conditional -- 'it matters IF another screen is ever authored' -- in
the same file that already recorded such a screen. Future tense over a fact twelve
keys away. Corrected to name DIFFICULTY concretely.

MenuFlow.initial_focus's buttons[0] fallback is now documented as a repair for
broken data rather than a default, and that is measured rather than fastidious: if
a screen reaches that line silently the port shows a top-item default for a game
that does not always have one. No authored value moves -- DIFFICULTY is not a
GP_TITLE build and EXTRAS keeps ptbtn11, correct under either reading. Walk re-run
unchanged.

It does not settle the question, which is about reset rather than opening. That
needs the cursor moved inside DIFFICULTY, left and re-entered, and its forward
path crashes the guest at SELECT DATA so the run must go back rather than on.

No checker either of us has built would have caught this. Every instrument here
verifies that a claim matches a value; nothing detects that an answer already
written down is not being connected to the question it answers -- and mine had
both halves in one file.

It also makes the previous iteration's restraint look better: declining to promote
'4/4 submenus reset' to a rule was argued from the principle that a generalisation
should not pre-decide the next screen, and the next screen turns out to be one the
generalisation would have got wrong.

13bc0b02f7 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.

cf3a9a0454 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.

23dda95643 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.

c909d1dc49 port: the contract I read is 3185 lines shorter than the contract
docs/port/HANDOFF.md on main is 926 lines, last touched 0fd8e69 on 2026-08-29.
The live one is 4111 lines at 27938aa, +3930/-745 across 96 commits I have never
read, several of them addressed to the port by name. The Decoder writes HANDOFF
on origin/auto/no-disc-and-menu-captures; main is a hundred-odd commits behind
it; I open main's copy every iteration as instructed.

So the rule meant to prevent this cannot detect it. tools/port/blocked-provenance
recovers each row's derivation from history rather than memory -- git log -S on
the row's key phrase -- and all 27 open rows derive from 0fd8e69, because
HANDOFF-on-main has not moved. A constant cannot separate a fresh row from a
rotten one. Withdrawn in BLOCKED.md: 'HANDOFF has not moved in four milestones'
was missing the qualifier that carried its meaning.

The tool's first version silently missed its own known positive: P6 looping vs
712cac8, whose 9.44 s answer this port already ships. 'looping' did not stem to
'loop', 'menu' was stoplisted, and a >=2-shared-words threshold dropped the rest.
The threshold was the defect -- two common words outscored one rare one -- so
ranking is now by log(N/df) with no cutoff at all, and the control passes at rank
1 of 7 without touching the stoplist. Every discard is counted: struck rows,
sub-rank pairs, stoplisted words. Same rule applied to check-claims, which now
reports the 40 occurrences it suppresses; the Decoder reached it the same day
from the opposite failure, a silent suppression path making a clean run
unfalsifiable.

The reading list found two open rows already answered: the plate's pulse period
(120, not 105) and the main menu having no idle self-return, which refutes the B
row's own reasoning.

Refutation attempted on '+0x08 is the loop length', the claim the port was about
to build on. It survives: their falsifier re-run on my own read of the disc gives
0 violations in 1781 records, and on the eight records this port animates their
table reproduces cell for cell. Adopted -- screen.rs exports loop_length_units
and ScreenView._loop_period prefers it, announcing any disagreement rather than
silently resolving it. The value does not change: authored/timing.json already
had 120 from a wall-clock measurement, so a disc field and an emulator stopwatch
agree while sharing no instrument.

Two asks filed: the field is exposed in no public API on any ref, so the port
reads four bytes it should not own; and eleven focus records declare the same
120-unit cycle while only the plate is authored to animate, which is behavioural
and not mine to infer.

Every asserting check passes; oracle RMSEs unchanged, as 120 == 120 predicts.

8337aaf29c 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.

940175d62f 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.

1e02008f55 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.

d9b1137c93 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.

ad8e18de7c 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.

4956740c42 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.

8fac01ed4e 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.

3751f86a86 port: the oracle harness was nondeterministic and I quoted it for a dozen iterations
verify-capture's main_menu row reads 13.30 / 13.27 / 13.25 / 13.26 across runs
this session while every other row is identical to the digit. I cited those
numbers repeatedly, including in the rest() adjudication.

Cause: the focus ring spins on time_units raw rather than the pose clamped by
holding -- deliberate and correct, since the ring is the one thing on a settled
screen that keeps moving -- so its angle at capture is set by the wall clock.
extras is stable because nothing there spins.

--loop-phase already existed and did not cover it: it pins the looping focus
record phase, while the spin is a second free-running clock I guarded once and
never connected. Extended loop_phase_units to pin the spin too, and verify-capture
now passes --loop-phase=0 at all four render sites.

The control matters because the drift was intermittent -- three unpinned runs gave
13.25, 13.26, 13.26, so three pinned runs agreeing would prove nothing. Phases
0/30/60/90 give 13.2583 / 13.1991 / 13.2637 / 13.2588: the pin is live and the
0.065 spread is the whole of the observed drift.

Non-finding recorded so nobody mines it: phase 30 scoring lowest is not evidence
about the ring's real phase -- 0.065 against a ~13.2 gamma floor is 200x too
small. A margin only means something against the noise it sits on.

No conclusion changes: the smallest margin any of them turned on was 0.14%
differing area.

d84c17457e port: count the fallbacks instead of inspecting them; black_hold's absence is now audible
The Decoder sharpened the sweep in a way that invalidates part of how I ran it: an
in-range fallback cannot be caught by inspecting output, because the output looks
exactly like the true case -- the only way to know is to count how often it fires.
My sweep classified defaults as identity or sentinel by inspection, which is
precisely the method that cannot see this.

Counted: rotation_deg -> 0 fires 0 times in 866 keyframes and 178 rest poses, and
ramp is present in authored/. So rotation is read, not invented -- the same
conclusion they reached for design size, reachable only by counting.

The count exposed one I had waved through twice: black_hold_units defaults to 0.0
and its authored value IS 0, so deleting the entry would be invisible -- same
behaviour, no error, and the reasoning in black_hold_why (four measured gaps, why
0 over the better-fitting 4 or 6, the tripwire) silently stops applying. Fixed the
same way as exit_ramp_units: fallback is -1.0 and an absent key raises an error
naming what was lost.

The control is the demonstration: key present 0 errors, key deleted 1 error, and
the render byte-identical either way. No output inspection could have detected the
deletion.

Does not change the value: still 0, still wrong by 4-6 units on three of four
measured transitions, still no rule. Only its absence is now audible.

bd1415b29d port: the refuted 24-unit constant was living in a default; make it loud instead
ScreenView.exit_ramp_units defaulted to 24.0 -- the constant HANDOFF ask 2 told
this port to author and that it refused, since the file's own ramp is 10 units.
The authored entry was deleted as progress when the corrected record layout
removed the unknown, and the default plus boot.gd's timing.get(..., 24.0) made
that deletion a no-op.

Both use sites are unreachable on today's export (866 keyframes, 0 untimed), so
the branch is kept for an older export but no longer invents: the default is -1.0
meaning not supplied, and an untimed group now raises an error naming the screen
rather than fabricating a duration.

My first verification accused the change: main_menu 641941 px and extras 226009 px
changed, on a branch that cannot execute and with no error raised. The cause was
--screen=X --capture= firing at an uncontrolled instant -- t=9.00 in the earlier
run against t=8.00 in the later one, one unit apart mid-build-in. Three runs now
are byte-identical, so it is not noise; the instant is stable within a session and
moves between them. Re-run with --time=1.0 pinned, old against new is
byte-identical on all four screens.

Records the harness limitation: --screen=X --capture= cannot be used for
before/after comparison on an unsettled screen, which also explains the earlier
settle-vs-rest confound.

Also corrects my overstatement that other tools call the CLI -- verify-screen is
the only one, checked.

9233ff1e08 port: the rest() flash defect reaches all four splashes I ship; the port survives it
The Decoder censused rest()'s dwell fallback from the file side: 2305 elements
have no plateau, 1697 of those get a visible pose, and in GP_TITLE all four
visible fires are on the splash screens this port ships. Confirmed in my export.

Refinement to their description: they named the [0:a0 15:a255 30:a212 45:a0]
shape, but palogo_gamearts_eff and palogo_seta_eff hold 255 through t=30, so
their fallback lands on the flash PEAK rather than its decay. Same defect, worse
pose.

The port ships the right frame and there is now a number for it. Publisher splash
against the committed oracle capture: timeline (shipped) RMSE 2.17 / 0.01%
differing; --pose=rest 9.05 / 0.75% -- 75x the differing area on a screen I ship.
So the rule added to verify-screen's header after the title_jp mistake
generalises, and is demonstrated against an oracle rather than argued.

What did need fixing: ScreenView logged '(transparent at rest)' for every skipped
element whatever instant it posed, so it said that about palogo_sqex_eff, whose
resting alpha is 212. That is the same rest-versus-posed-instant confusion that
cost a wrong conclusion, pre-printed in the log. It now names the instant.
Controlled both ways: timeline says 'at t=6' and skips the flash, --pose=rest
still says 'at rest' and draws it.

81352459e3 port: verify-screen was nondeterministic; pin the pulse phase in the harness
Running the full set after the plate fix, press_start returned over3 5021, 8919,
5021 on three identical runs. The plate's looping focus record takes its phase
from time_units, which free-runs, so the captured frame lands wherever the grab
fell -- while the reference renderer cannot pulse at all.

The port is not the thing that is wrong: the pulse is measured and a thing that
pulses does not stop because the screen arrived. ScreenView.loop_phase_units pins
it, negative means free-running and stays the default everywhere, and only the
harness passes --loop-phase=0.

Controlled: pinned, 3 runs identical; free-running, 3 of 4 identical and one
different. That 3-of-4 is why it survived -- it looks deterministic most of the
time, and without the negative control a no-op flag would have been
indistinguishable from a fix.

With the phase pinned press_start reads max 1 / over3 0 OK -- the recorded
baseline exactly. Fifteen of sixteen rows now match.

The sixteenth, title_jp, has genuinely drifted: 155/20498 -> 233/61208,
deterministic, on the Godot side, localized to one 350x396 block at (405,74).
There is no capture of the Japanese title, so I can say the renderers moved apart
but not which moved. Recorded as an ask, not resolved.

7dc5117a09 port: the PRESS A plate comes back after B, and it did not here
The Decoder measured that after B from the menu the plate is re-drawn (daf8f47).
The port landed on a BARE title: _menu_arrive drops the overlay -- correct, the
plate goes with the screen it was measured on -- but nothing put it back, since
_overlay_spec is cleared the instant the overlay is raised and only the boot
sequence ever set it. Confirmed by running it: ten title elements, no ptbtn00.

_rearm_overlay_for reads the declaration out of authored/flow.json's boot step
for that screen rather than naming press_start, so the plate returns by the same
path and shared clock as on boot, with NO new constant. Controlled both ways:
cancel raises it, entering EXTRAS (no overlay declared) raises nothing.

Script steps now carry an elapsed timestamp, without which the port's own press
latency could not be compared to a measured one. With it: B at 1.01 s, title at
1.37 s = 0.36 s, against their measured <= 0.4 s -- nothing was fitted to that.

The plate's RETURN time does not agree: 4.33 s here against their 7.3 s to pulse,
of which up to 2 s is pulse-detection phase. Not adjusted -- an authored delay in
this same block was already refuted once. Recorded as an ask.

auto_repeat and title/on_cancel upgraded to MEASURED on their run.

90ea61b472 port: the runtime now says what the voice export is missing, at the moment it plays it
The manifest has carried the gap for weeks and the runtime printed '+ voice ADV'
and nothing else. A reader of manifest.json gets a paragraph; a person LISTENING
gets clean dialogue and no way to learn a stream is absent. NEW GAME already
announces the screens it jumps over; audio had no equivalent.

ManifestAudio gains  -- one line naming what is KNOWN missing, absent
meaning nothing is known rather than nothing is wrong -- and MenuAudio carries it
so _play_video can print it. Verified on the boot's ADV and P7's S00A.

The first version of the message was FALSE for one of the two assets: it said
'one is a start-truncated stream', which is ADV's story, where S00A's dropped
chunks are digitally silent. Caught by reading the output for both, which I
nearly skipped because the ADV line was obviously right. Now states the counts
and points at the entry's why.

A message generated once from a template but true only for the case it was
written against is harder to see than a wrong number -- the sentence is
well-formed and confident in both places.

19acff7a41 port: a static overlay advances instead of freezing; and their pulse floor is unreproducible
--screen=X animates X but froze an overlaid Y -- my earlier fix overshooting,
replacing a frozen-too-early overlay with a frozen-at-arrival one. The plate
pulse made it visible: oscillating on the boot path, flat here. Now offset, not
pinned: the overlay starts at its settle and takes the main view's delta. Static
path now pulses 95.85 -> 115.41 against the boot's 95.68 -> 115.52; still frames
unaffected and title_plate holds at 0.00%.

Both halves were mine a week apart, and the over-correction was invisible until a
third change gave it something to be wrong about.

Refutation attempt on their pulse floor: 159/714/1520 is NOT reproducible from
the published description. My counts on the same capture are 3-5x theirs at every
threshold, so their region must be a tighter crop; neither region nor threshold
is stated. The RATIO survives robustly -- 1:10.4-10.9 across a wide band,
bracketing their 1:9.6 -- so 'steady base plus pulsing glow' stands, which is all
the port's implementation rests on.

aa6be8e809 port: the plate pulses -- restore the looping record, over the base rather than instead of it
Ask #1 measured: held at the title with no input the plate oscillates ~23 cycles
per window with no decay and NEVER goes off -- floor 159 thresholded pixels,
pulse bottoming at 714. A glow alone cannot do that (0 -> 80 -> 0); a steady base
plus a pulsing glow can, and 714/1520 are base-only and base-plus-glow.

The port already had the base right: ptbtn00's fade to 0 at t=244 is its EXIT
ramp, and while held the base sits at alpha 255. The glow was missing.

The defect was in the renderer, not the entry I deleted on 2026-08-29. _draw
treated a looping record like a focused one -- drawn INSTEAD of the base, which
is right for a focused button and wrong here. I deleted the right thing for the
wrong reason. A looping record now draws OVER the base and the entry is restored.

Rendered: 95.68 base only, 115.52 at peak, period 1.980 s against a declared 120
units = 2.000 s, ratio 0.990. Visible on the boot path; not under --screen
--overlay, where a static overlay poses at its arrival by design.

Authored in UNITS on their instruction, with their three limits verbatim: one
boot, does not distinguish boot from attract title, and 714/1520 is not an alpha
ratio so no duty cycle is inferred.

141cef4047 port: wire flow.json's dwell, assert the three authored values the port hardcodes
Applying the prior from six prior findings to authored/ itself: five keys had no
reader. dwell, ramp, left_right, input_during_transition, stems.

dwell is the one that mattered. Its own text says a measured hold goes there and
a number placed there did nothing -- and two iterations ago I asked the Decoder
for measurements destined for that slot. Wired now, and it stays EMPTY: the
splash dwells are declared on the disc and measured to agree.

I wired it to the wrong branch first and it did nothing, silently -- holding
longer after settle is absorbed because the screen still leaves at exit_time +
black_hold. A dwell must delay the departure. Caught only by testing the control:
+120 units moves the transition 4.46 -> 6.43 s.

ramp, left_right and input_during_transition describe hardcoded behaviour and are
written like switches. Rather than invent the missing implementations, they are
now asserted against the value the port was built for, naming the file -- which
is the distinction left_right's own why claims to make and was not making. The
validator is called, not merely defined.

2fe1f06599 port: --focus was ignored on the menu path; focus rendering now verified against the oracle
live-main-menu-options-focused.png -- the only capture of a known focus state --
was untestable because --focus= parsed, was stored, and was overwritten by the
authored initial focus on every _menu_enter. Every run logged focus ptbtn01
whatever was asked for. Now pushed into the menu model so navigation continues
from where it was forced.

With it working, each capture picks out exactly one button: ptbtn04 at 0.1355%
against 0.70-0.82% for the others on the OPTIONS capture, and ptbtn01 at 0.0705%
against 0.72-0.84% on the plain one. 5x and 10x discrimination. First time the
port's focus rendering has been checked against the game at all -- the existing
main_menu row uses an authored focus and could never have caught a focus error.

Records in flow.json that live-main-menu.png shows NEW GAME focused, so the
authored initial_focus matches the one frame it can be checked against -- and
that this does NOT overturn Q5's measured instability. It stays authored.

Adds main_menu_options to verify-capture at 0.13%.

a170e1fbc6 port: a second capture closes the sweep-geometry question; title+plate matches at 0.00093%
live-title-press-a.png was unused in the corpus. Posed at t=237 -- inside the
plate's 8-unit window -- the port matches it at 0.00093%, against 0.0124% for
the no-plate capture at leaf phase ~400. Two captures, two different phases,
both under 0.013%: a systematic sweep-geometry error would leave a floor in
both, so last iteration's caveat is closed.

Sweeping the whole screen's instant against capture 1 gives at best 0.148% at
t=230 -- 10x worse than the leaf-only fit. So that capture is the screen SETTLED
with the sweeps still looping, which is the first independent evidence for the
authored loop_leaf decision.

Fixes the cause of a flat 1% floor: --screen=X --overlay=Y pushed the raw
elapsed clock into the overlay (9 units at capture), so press_start drew nothing
-- the flag whose purpose is 'put the plate on the title'. A static overlay now
poses at its own arrival; the --boot shared clock is untouched.

Adds title_plate to verify-capture at 0.00%, the most sensitive row in it. Its
instant is FITTED and labelled as such.

Also records that I nearly committed a wrong cause for the overlay bug: I wrote
that nothing drives the overlay's clock outside a sequence. It is driven, every
frame, from view.time_units.

9610662b82 port: add --leaf-time, and the title's residual is the sweep phase (~400 units, not 357.7)
The Decoder's refined sweep fit had never been testable: verify-capture passed
it as a whole-screen --time that pose_at discarded, and asking for it honestly
poses past the title's group end. --leaf-time separates the leaf's clock from
the screen's.

Controls: the renderer is deterministic (3 runs bit-identical) and the sweeps
move 0.40% of the frame between phases, so the comparison can see them.

Sweeping the full 600-unit span gives a sharp basin at 390-415 units (0.0124%)
against 0.2532% at t=357.7 -- 20x. So the title's 0.21% residual is the sweep
phase, not structure: at the fitted phase it matches the capture as well as the
splashes do.

NOT adopted: the port loops the leaf freely and re-posing the harness to the
fitted value would be tuning until they match. Filed instead, with the question
of whether 357.7 and this are even the same quantity.

Also verified last iteration's settle-window change was surgical: only
press_start and its twin moved, 14 screens unchanged including title's
Decoder-confirmed [160,236]. Settle-window ties exist on 4 screens but all sit
under the 30-unit bar, so the arbitrary tie-break never reaches the runtime.

29a5b4a394 port: the PRESS (A) plate could not be drawn at any instant -- four faults, and a misquoted number
1. --time= was silently ignored on any screen with a settle window >= 30 units:
   pose_at overwrote the requested instant with settle_instant. ScreenView.frozen
   now marks an explicit instant and skips both clamps.

2. press_start's settle window was [0,214] -- the dead stretch BEFORE the plate
   exists -- so its settle instant was t=107, where the element is alpha 0. The
   exporter now rejects intervals in which nothing is visible. title keeps
   [160,236], the interval the Decoder's draw stream confirmed.

3. My authored looping_focus_records entry for press_start/ptbtn00 drew a dim
   focus record INSTEAD of the plate's own sprite: max 0 vs max 252.5. Deleted --
   an authored guess that overrides a decode with a worse answer is removed.

4. verify-capture passed --time=5.9617 for the title and it was never applied.
   Every title figure it has printed, including the 0.26% quoted to the Decoder,
   was measured at the settle instant under a note claiming t=357.7. Both rows now
   pose by omission and the note matches. title is 0.21% honestly; splashes
   unchanged at 0.01%.

The boot's end artifact now contains the plate (region mean 95.7 vs 33.6).
Corrects last iteration's BLOCKED row, which had the entry's effect backwards.

1. --capture with --script photographed before the first press (t=0.133 s, 10 of
   16 elements transparent). Two runs differing by two presses came out
   bit-identical and I read it as 'runtime focus never changes'. Deferred to the
   end of the script; verified max 235 and t=82 units.

2. --boot --capture= wrote NO FILE: _finish_boot() is reachable only from the
   overlay-quit branch, but line 412 quit first because _overlay_spec is cleared
   when the overlay is raised. Pre-existing, confirmed by stashing. Fixed by also
   requiring _overlay_quit_at < 0.0.

3. The artifact that now exists shows the boot's end frame is bit-identical to
   the title alone -- no plate. ptbtn00 is opaque for 8 units (236-244) and the
   boot captures at 246.54, because it waits for build 4 to finish fading at
   t=261. Both halves of that are sound and they are incompatible. NOT changed;
   filed, since what settles it is what the game does after t=244.

Defect 3 was invisible while defect 2 existed: a capture flag that writes nothing
cannot show a missing element.

Also records that runtime focus is FINE -- my contrary reading came from 410
files whose names did not match the flag I passed.

e5398be93b port: add wait:<seconds>, observe the bed's loop, and measure the seam at 3.4 s of silence
The port could not be asked to run for a stated duration -- a bare  step
is a no-op that returns at settle -- so nothing after the settle point was
observable. An 87.7 s bed on a harness whose longest menu run was 7 s.

The bed loops at 87.8 s against the track's 87.7 (r=0.947 and 0.885 on a clean
bed-only recording): loop: restart behaves exactly as authored. First
end-to-end observation of P6 looping.

The authored 'audibly wrong at the seam' is confirmed and quantified: 36
consecutive near-silent 50 ms windows, 84.40-87.80 s, about 3.4 s of silence
after a fade from RMS 2057 to 431. Recorded in authored/audio.json. It does NOT
license trimming, which would still invent a loop point.

My first wait: used create_timer and ran 39% long (30 s requested, 41.7 s wall)
because an idle scene throttles the delta it counts down on. Now polls
Time.get_ticks_msec: +4.6%. Checked before generalising: over a boot the port's
clock tracks wall clock within 4%, so animation timing is sound and the earlier
splash-dwell agreement stands.

Also records that the envelope correlator is unreliable for music under music --
0.15-0.42 for every candidate, peaks moving with window and template. I was

e6fc2977ff port: make ScreenView say what it could not draw; refute 'first-declared paints first'
skipped[] has been tracked and read by nobody since P1, under a comment saying a
silently missing element looks like art. _note_structural prints from inside
ScreenView rather than returning a value for a caller -- routing it through a
caller is exactly what did not happen. Structural skips only; transparent-at-
rest is ordinary animation. Zero found today: a guard, not a fix.

The first version of that scan was a FALSE PASS: screen_view.gd did not parse
(a line inserted at three tabs inside a four-tab block -- the substring assert
matched a shallower indent), so grep counted zero from a dead script. The scan
now counts the summary line as a positive control.

Refutes 'the first-declared element paints first', which would have made the
forced-backdrop rule redundant since all six forced elements are index 0. False
on 8 of 16 screens -- decisively on main_menu, where index 0 is pteff00, painted
LAST, and pteff00 is a measured control.

77292e98fc port: withdraw 'the boot is known too fast' -- the splash dwells are declared and the port already played them
The Decoder measured both splashes over 3 cold boots: publisher t=0..255,
developer t=0..210, the developer agreeing with wall clock to 1.1%. The port
emits each declared value plus the 9-unit black hold, exactly. No code change.

My error was the generalisation, not the arithmetic: build 4 is the title, whose
exit is caused from outside its timeline, so it holds; a splash's exit is caused
by nothing, so it plays out. I used the one boot screen the port is unaffected
by to overturn the two it governs. Declining to scale by 9x while adopting the
conclusion that implied was half a caution.

Also refutes their two splash boundaries as not comparably anchored: 2.237 vs
2.414 units/frame in one boot, and the publisher has a glow symmetric with the
developer's three.

2e29572b02 port: the clock freezes at settle -- my window is the game's, and the boot is known too fast
The Decoder measured build 4's top-level clock stopping inside [160,236]. The
exporter computes title's settle window as [160,236,198] from the file alone.
Same interval, two independent methods -- the first evidence for the settle
instant that does not come from our own renderer. ptcopyright reaching alpha
255 exactly at t=160 agrees from a third direction.

Corrects a claim in three places: timing.json, flow.json and boot.gd all said a
screen's dwell IS its keyframe group and the port reproduced 'the disc's own
pacing'. Build 4 declares ~120 presented frames and dwelled ~1100. The decision
to hold zero extra stands; the claim that it was faithful does not.

Checks their two declared spans against the file: both exact, with a 106-vs-105
interval-convention quibble that changes nothing.

3e578882c2 port: the title's sweeps loop, the black hold is 9 units, and one claim refuted
THREE THINGS FROM THE DECODER, one of which I am not taking.

REFUTED: "the developer splash is one composited quad, the bounding box of the
three logos". The observed quad is 525x259 at (378,155). The three logos'
bounding box is 500x421 at (390,164) -- a 259-tall quad CANNOT contain them, and
palogo_anima alone starts at y=449, thirty-five pixels below that quad's bottom
edge. The observed quad matches the union of gamearts_eff and seta_eff, 521x261
at (379,154), to about four pixels in every dimension -- and both of those are
TRANSIENTS my own census flagged, dark by t=45, so a frame containing that quad
is a build-in frame rather than the settled screen. I cannot see their draw
stream, so I sent the arithmetic rather than a verdict, and the port keeps
drawing three: I will not stop drawing an element on a claim whose stated
identification excludes that element from its own bounding box.

THE BLACK HOLD IS 9 UNITS, NOT 12. I authored 12 from Q7's luminance plateau of
0.17-0.23 s, supported by the menus' transition quad. The Decoder counted
SUBMITTED QUADS instead -- luminance cannot separate the outgoing fade's tail
from true black. Four frames with no sprite quad at all, at 2.284 units/frame
derived from the disc as its own clock, gives 9.1 units = 0.152 s (6.9-11.4).
That overlaps the luminance figure only at the top, and the true black is SHORTER
still since both boundary frames carry picture. My 12 was supported by analogy --
a different screen's quad on a different path -- and a number that fits by
analogy loses to one measured in place. verify-dwell's bound moved with it; both
screens still agree.

THE TITLE'S SWEEPS LOOP. The oracle shows the quad oscillating over its whole x
range and resetting hard, one reset in the first title dwell and two in the
second. The loop-length field could NOT have settled it, correcting a hope I had
stated: both records declare exactly their last keyframe time, slack zero, and
"loops at 600" and "runs once for 600 and stops" write the identical header.
Verified on the two sweeps' LCM, since their periods differ: 600 and 720 realign
at 3600 units, mean diff 0, against 0.438 at half that.

Scoped to the title. The menus declare the same lengths but the oracle
measurement is of the title, and my own weak evidence points the other way there
-- best match with the sweeps off-screen, three times worse mid-screen, against a
73% on-screen duty cycle if they looped. Two weak signals in opposite directions
is a reason to scope, not to pick.

7230fa846e port: the publisher residual was a missing black hold -- we had both dismissed it
I carried this as "0.03 s outside a composite bound, probably a property of the
bound rather than the game", and the Decoder agreed. Both wrong, and the way it
was settled is the point: I stopped reasoning about the bound and filmed the
transition.

At 0.05 s the port fell straight out of the publisher's fade into the developer
logos -- mean 5.06 -> 0.32 at t=4.20, then 5.65 at t=4.25. NO BLACK FRAME AT ALL,
where the oracle measures a 0.17-0.23 s pure-black plateau (HANDOFF Q7). The
bound was fine; the port was missing a fifth of a second of black, and had been
since P3.

Authored at 12 units because the boot path has nothing to read it from:
publisher_logo and developer_logos each carry a single palogo_eff0, a 1280x720
primitive with ONE keyframe at t=0 -- static, not a transition ramp. The menus'
quad declares black for 12 units and 12/60 = 0.200 s sits mid-range, so the
number is the disc's where a screen has one.

Filmed after: t=4.25, 4.30, 4.35, 4.40 all at mean 0, then the developer logos at
4.45. publisher interval 4.26 DIFFERS -> 4.47 agrees; developer 3.62 -> 3.73,
still agrees. Settled-frame comparisons untouched, as they should be.

THE LESSON IS THE SHAPE OF THE DISMISSAL, NOT THE NUMBER. "A 0.03 s miss against
a bound composed from two measured ranges plus jitter slack is more likely a
property of the bound" is plausible, was accepted by both of us, and was wrong.
The composite bound is why the miss looked small -- the underlying gap was 0.2 s
-- and a plausible explanation for a small number is how a real defect stays
hidden. The film cost one command.

Also recorded: the Decoder has reproduced across two build-ins that the console
NEVER draws ptlogo_back2eff3 (0 draws against ~5 expected), with sampling phase,
invisible draws and position error all ruled out -- but WHY is not established,
and nothing in eff3's record differs from its neighbours. The port keeps drawing
it, deliberately: dropping an element the disc declares on a measurement with no
mechanism is authoring a behaviour neither agent can derive, and nothing this
port gates on would notice, since the flashes live only in the build-in and
verify-capture compares the settled frame.

fb472e8dfc port: pose a settled screen at ONE instant -- title 1.81% -> 0.26%, splashes to 0.01%
The Decoder's finding, applied. `rest()` returns each element's last hold
keyframe chosen independently of every other element: right for anything that
ends the screen settled, exactly wrong for a transient. The title's
ptlogo_back2eff1 is a two-frame flash (0 until t52, 255 at t54-56, 0 by t58), so
its last hold IS the flash peak and rest() left it burning -- five of them, drawn
at once.

The settled instant is the longest interval containing no keyframe time, over a
bundle's TOP-LEVEL elements. Reproduced here before adopting: title [160, 236],
midpoint 198, the Decoder's number to the unit. The top-level restriction is what
makes it match -- including the ptloop leaves gives [269, 540].

AGAINST THE ORACLE:

  title            20.92 RMSE  1.81%  ->  14.61 RMSE  0.26%
  publisher_logo    9.05       0.75%  ->   2.17       0.01%
  developer_logos   8.86       0.33%  ->   3.05       0.01%
  main_menu                    0.08%  ->              0.08%   window too narrow
  extras                       0.19%  ->              0.19%   window too narrow

Seven times fewer differing pixels on the title, seventy-five times fewer on the
publisher splash, whose differing region is now a 13x18 box. The largest
correctness gain this port has had, and none of it is mine -- it is a decode
computed from the keyframe table with no reference to any capture.

APPLIED ONLY WHERE THE WINDOW IS WIDE, and the bar is not invented. This export's
widths split with nothing in between: 214, 190, 145, 76, then 12, 12, 8, 4. The
bar is 30 units -- the Decoder's disc-wide census puts the knee there (30% of
bundles >= 30, 42% under 10, the latter mostly loop* fragments meant to be in
motion) and this export's screens sit 4x either side with nothing between 12 and
46. Two independent populations agreeing on where to cut.

Checked unbroken: boot pacing unmoved, scripted walk runs end to end with focus
restored.

Also recorded: my "34 focus-record elements, only 2 varying" is right for
GP_TITLE and reads as a fact about the format -- disc-wide it is 210 varying, 202
with rest() at the peak, concentrated in the paks a wider port reaches next. And
their sharper framing, which I have adopted: a pulsing element has no resting
pose at all, so rest() is MALFORMED rather than mis-answered on one.

521b0b1f85 port: the focus ring had silently stopped, and the plate's period is now the disc's
BLOCKED said the record-layout change touches five things: pose_at,
settle_units, spin_period_units, exit_ramp_units and the plate. I checked two,
reported that, and did not work the rest of the list.

`spin_period_units` required "the first timed and the second untimed". Under the
corrected layout the ring reads t=0 rot=0 and t=120 rot=360 -- both timed -- so
the rule returned 0 and THE FOCUS RING STOPPED SPINNING. Nothing reported it: a
period of 0 is a legal "this element does not spin".

Rewritten to take the SPAN between the two poses: 120 - 0 = 120 units, the same
number the old rule produced, which is evidence the corrected layout is
self-consistent rather than merely different. Verified the way P5 verified it,
by bit-identity one period apart on the ring's own 60x60 box so the ptloop sweeps
cannot confound it: 0 at +120 units (twice), 8.61 at a quarter period, 8.88 at
half.

Three wrong instruments on the way, and the sequence is the lesson. A whole-frame
`max` saturates on one rotating edge (adjacent frames scored 131 with a mean of
0.022). A live --menu filmstrip jitters by up to a frame, which is ~3 degrees of
ring. And a whole-frame comparison is dominated by the sweeps, which move 480 px
over one ring period. `--focus=<id>` was added so a --screen run can draw a focus
record deterministically, which is what made the check reproducible.

THE PLATE'S PERIOD IS NOW 105, THE DISC'S OWN GROUP LENGTH, and it disagrees with
the measurement. The ambiguity the entry carried is gone -- it used to say the
cycle might restart at t=6 rather than 0 and that nothing separated them; the
group now runs t=0 to t=105, both at alpha 0, and there is one reading. But 105
units is 1.750 s, or 1.906 s scaled by the factor the ring shows between its
declared 120 and its measured 2.177 s -- about 17% below all four corpus timings
(2.12 / 2.19 / 2.34 / 2.31). The old 129 gave 2.34 s, at the top of the range,
which is why it looked right.

129 was the last timed keyframe plus exit_ramp_units, and that constant is
deleted. A period built on a constant that no longer exists cannot stay even
though it fitted better, so the port ships the disc's number and says it is
wrong. Verified bit-identical 105 units apart, 0.83 at 30 units.

ace071dd7b port: delete exit_ramp_units, invert the format's own rule, and guard a scale-0 leaf
FOUR THINGS, and the first is what MISSION section 3 calls the measure of
progress.

DELETED `exit_ramp_units` AND `exit_ramp_seconds`. They were authored because the
disc had no time slot on a group's final keyframe, so the ramp into it was the
one unknown duration per screen. Under the corrected record layout that keyframe
does not exist -- a group is an 8-byte header then frames x {u32 time; 36-byte
pose} and every pose is timed. VERIFIED DEAD BEFORE DELETING: setting it to 9999
(166 s) moved the boot's transitions by 0.04 s, which is wall-clock jitter, and
both uses in ScreenView are gated on a condition that no longer fires on any of
the export's 866 keyframes.

INVERTED THE FORMAT'S OWN RULE. `check.rs` enforced "the final keyframe has no
`t`; the disc has no time slot there" and FORMAT.md stated it. Both are now
backwards, and the validator fired 150 times on a re-export. I had not run
`check` between pinning the tag and measuring against the oracle -- the pixel
harness was green while the format validator was failing on every screen with a
multi-keyframe group. A correctness harness does not replace a format one; they
fail at different layers.

GUARDED A SCALE-0 LEAF, which the Decoder hit in its own renderer: its leaf
branch marked the element drawn unconditionally while the blit returned early on
zero scale, so a scale-0 leaf suppressed its parent and blanked the element --
live on all four loading screens. This port did not have the bug only because
authored/rendering.json happens not to list pgloading_loop5. That is an accident
of a gate written for another reason, not a defence, so `_draw_leaf` now reports
whether it drew and `_draw` falls back to the parent.

ISOLATED THE PACING QUESTION rather than leaving it as a suspected regression.
Legacy association: publisher 4.70 agrees, developer 3.92 DIFFERS. Corrected:
publisher 4.26 DIFFERS, developer 3.62 agrees. Both misses are ~0.03 s outside a
composite bound. The association traded which screen is marginally out; it did
not regress the pacing.

Bumped the pin c -> d for the parser and audio changes. Its headline renderer
change does not reach this port: sylpheed-cli builds from the workspace crate.

cb616ab9af port: implement the decoded leaf composition -- and it does not close the 1.82%
The Decoder decoded the rule I refused to guess: draw the leaf on its own
timeline, do NOT multiply the parent's alpha in. Multiplying is refuted rather
than unsupported -- at the fitted time the parent has expired, so leaf x parent
predicts zero for both quads and the sweeps would be invisible. They are drawn.

Implemented: `_draw_leaf` runs the leaf unclamped, like the spinning ring and for
the same reason -- held at its own rest.t the leaf sits at x=1521, entirely off
the right edge, so `holding` would delete the sweeps rather than settle them.

AND IT CHANGES NOTHING MEASURABLE. The title is still 1.82% against the oracle:
1.82 at t=261, 1.81 at t=355, 1.79 at t=420. At t=355 my interpolation puts the
leaf's top-left at x ~ -324, off-screen left, where the Decoder's model puts the
quad's CENTRE at 981. Those cannot both be right, and it is not something to tune
away -- it is a disagreement about how the leaf's keyframes become a placed quad,
most likely in the pivot and the rotation about it. Handed back with both
numbers.

So: the exporter no longer drops the data, the composition rule is implemented as
decoded, and the port's largest oracle gap is exactly where it was. Fixing the
export was necessary and not sufficient.

TWO FLAGGED ELEMENTS DELIBERATELY NOT DRAWN, in authored/rendering.json with
reasons. title_jp/ptlogo_eff2 (parent 125%, leaf 100%) is the same shape and is
the element DECISIONS has recorded since P1 as the largest render disagreement --
but the Decoder said plainly "I have not tested it", and drawing it would extend
a decode past the case it was fitted on. pgloading_loop5's leaf is scale (0,0),
and scale-0 is one of the three historical failures this corpus names.

Neither can be adjudicated here: title_jp has no oracle capture, and
verify-screen compares against a renderer that draws no leaves at all, so ANY
leaf drawing increases that divergence whether right or wrong. Its max went
155 -> 232 when they were drawn, and that number is not evidence in either
direction.

c1edd13848 port: the title residual is a horizontal redistribution, and three of my own explanations are dead
`title` is the port's largest disagreement with the oracle at 1.82%, and last
iteration I attributed it to the moving ptloop sweeps without checking. Wrong,
and so were the two hypotheses I formed after it.

NOT THE SWEEPS. ptloop01/02 are 399x180 at (441,270) -- small and central -- and
their exported keyframes hold pos, scale and rotation constant. The difference
peaks at x~1088.

NOT AN OVER-HELD ELEMENT. Added `--no-hold` to render the alternative: playing
the title's groups past rest fades the screen to black by t=5.2 s, 30.97%
differing against 1.82% held. Holding at rest is right.

NOT A TIMING OFFSET. Sweeping the build-in gives 24.05% at t=1.6 falling
monotonically to 1.68% at t=4.18 and 1.82% settled. The capture is at the settled
end.

WHAT IT IS: a horizontal redistribution. Signed difference by cell shows the port
DARKER centre-left (-13.1, -8.3, -6.6) and BRIGHTER right (+16.0, +9.9), nearly
cancelling -- whole-frame means 63.8 against 62.5. Brightness in the wrong place,
not a level error or a tone ramp. It falls in the rows spanned by the two wide
elements ptlogo_back2 (1118x262) and ptlogo_back2eff (1133x280), with the column
profile falling off past x~1152 against their right edges at 1189 and 1197.

AND THE EXPORT CARRIES NO BLEND MODE. ptlogo_back2eff's keys are declared, id,
index, keyframes, kind_raw, layer, layer_source, pivot, rest, role, sprite --
there is no blend field, in this element or in FORMAT.md at all, and the port
composites everything with normal alpha. If the game draws `_eff` layers
additively, a wide gradient sprite would produce exactly this signature and
nothing in the export would reveal it. Asked, not assumed; I have not tested it,
and I am recording it because the three I could test are dead.

Recorded and NOT acted on: pteff02's rest.t is 46, where its fade is 25% black,
while its own group reaches 0x00000000 at t=236 -- so the port holds a black veil
the timeline removes. Third instance of rest.t naming a hold that is not the
settled state. It does not explain the residual: removing a darkening veil would
make the port brighter still, and it is already brighter where it disagrees.

`--no-hold`'s first version set the flag thirty lines before `view` exists and
silently rendered nothing, caught because the loop found no files rather than
because anything reported an error.

af1d69ed4b port: the PRESS (A) plate pulses -- authored per element, because 82 of 212 share its shape
The human listed pulsation as first-class and the port drew nothing: the plate's
focus record `ptbtn00f` was never reached, because press_start has no `buttons`
and nothing is focused. That it LOOPS is measured -- the corpus timed the period
four times (2.12 / 2.19 / 2.34 / 2.31 s) and you cannot measure a period unless
the thing repeats.

THE RULE I WAS GOING TO WRITE DIED IN THE CENSUS. The spinning ring is a rule in
the renderer because it has a disc-wide check: 16 of 212 elements match its shape
and all 16 are focus rings. The analogous shape for a pulse -- keyframes varying
only in alpha, first alpha equal to last -- matches 82 OF 212, including
ptcopyright, palogo_sqex, ptmsg and every _eff fade. A renderer rule on it would
make the copyright notice pulse. Narrowed to focus records it matches exactly one
distinct element, and a rule justified by n=1 is a special case wearing a rule's
clothes.

So it is a LOOKUP in authored/timing.json keyed <screen>/<element>, with the
census recorded beside it so nobody widens it later.

The period is 129 units -- the element's own group under the port's existing
model: last timed keyframe t=105 plus the authored exit_ramp_units of 24. No new
constant. 2.150 s at 60 units/s, 2.295 s at the ~28.1 fps the emulator presents,
against measurements of 2.12-2.34.

IT IS A CHOICE AND THE ALTERNATIVE IS STATED: restarting at the group's first
keyframe (t=6) instead of 0 gives 123 units = 2.050 / 2.189 s, also inside the
measured spread. Nothing separates them. t=0 is taken because it is where every
other group starts -- consistency, not evidence.

Verified the way the ring was, by bit-identity one period apart. 20 periods is
43.00 s = exactly 172 film frames: frames N and N+172 differ by 0-1/255, while
the control a quarter-second off (43.25 s) differs by 58.7/255. On the held boot
title the glow-box mean swings 26.0 <-> 37.7.

3aa74ea029 port: the intro had no dialogue because the voice is a separate asset, and I concatenated it wrongly first
A human play-test heard music under the boot intro and no voices. The obvious
reading -- the 5.1 fold dropped the centre channel -- is wrong. `ADV.wmv` carries
music and effects only; a cutscene's voice is a separate continuous XMA stream in
`sound.pak`, bound to the movie by the manifest in `tables.pak`. Nothing was
dropped. The exporter had never been asked for it, so every fidelity measurement
in AUDIO-VERIFICATION.md would have come back clean.

`audio::export_voice` resolves it with `media::resolve_movie_voice_region` and
never by filename: `RT01A`'s voice lives inside `VOICE_ADV.slb`, so a name match
is correct on exactly the two movies this port would have spot-checked. Decoded,
not authored -- so it runs outside the `authored/audio.json` block.

THE FIRST VERSION CONCATENATED THE REGION'S CHUNKS AND WAS WRONG. It produced
359 s of dialogue for a 137 s movie. Decoding and timing each chunk shows two of
them equal to six decimals and each spanning the whole movie -- HANDOFF Q10's
decoded two-stem shape on a second asset kind -- so they are summed at 1/n. The
error was visible only because the first version recorded the decoded length
against the movie's instead of clamping to it; the clamp `media`'s own doc
comment invites, and which `sylpheed-viewer` applies, would have produced a file
of exactly the right duration containing the wrong audio.

The dropped leading chunk matches no duration in its region and is NOT closed
here. It is the same signature as `BGM_103`'s third sub-wave, already open in
BLOCKED.md, now corroborated on an independent asset kind. Raised with the
Decoder; the manifest names every chunk dropped and its length.

Also in this commit, and separable:

* `--skip-at=SECONDS` -- `--script` structurally cannot press during a movie,
  because `_script_settled` waits while `_player != null`. That is why "does (A)
  skip the intro" had been read out of the source rather than measured.
* MISSION section 6 pins a 5.1->stereo matrix and this exporter has shipped a
  different one since P4 -- the same weighting, 7.65 dB quieter -- and said so
  nowhere. Re-measured with the right instrument (float decode, whole file, count
  the samples that would clamp, not a peak reading): the pinned matrix puts ADV
  at +4.26 dBFS on 4406 samples, while S00A never clips. So the pin overloads one
  movie and the constant is over-broad for the other. NOT changed -- the level of
  a mix is what section 6 reserves to a human. The export now carries a warning
  with the numbers.

b37ad246ff port: implement MODDING rule 4, and withdraw a red flag that was my own bad measurement
MODDING.md calls base-and-overrides "a design constraint on the exporter today,
not a milestone to add later". Nothing read `data/mods/` at all -- the directory
has existed since the monorepo merge with a .gitkeep and no code path anywhere.
Eight milestones shipped past it.

ExportTree.resolve() now shadows by path, and every read goes through it:
screens, sprites, cues, the music bed, movies. MenuAudio was reading tree.root
directly and would otherwise have made audio the one asset kind a mod could not
touch, for no reason a modder could have guessed. No manifest, no registration
step -- the path IS the registration, which is the whole of the rule. One tree,
not a stack: layering needs a load order and nobody has asked for one, so
data/mods/README.md says that rather than inventing it.

Every shadowed file is printed as it is read. The first version summarised in
_ready, before any asset had been read, so it always said "nothing shadowed yet"
-- a report structurally incapable of reporting anything, which is worse than
none because it looks like an answer.

data/mods/ was NOT gitignored, and that is a hole in a hard rule: a mod is
usually an edited game asset, and this was the one directory a user is invited
to put modified sprites in and git would have taken them. Now excluded except
the README.

Gate: a synthetic 203x43 magenta PNG (nothing disc-derived) at
data/mods/sprites/title/main_menu/ptbtn01.png changes 8501 pixels in a bounding
box of exactly 203x43 at the button's position, and `check` still passes.

RAISED, NOT RESOLVED: MODDING.md says the tree is data/base/, PORT-MISSION.md §3
and the exporter and .gitignore say export/. Both are mission files and only the
human changes a mission.

REFUTATION on Q3's paint-order key: 2 of 16 screens did not match a stable sort
by layer key -- but that was my test. pgloading_eff00.prm carries NO layer key
(layer_source "none"): a primitive with no sprite header and no implied-name
fallback. I sorted keyless first; the decoders put it last, which is right,
since it is the full-screen black quad and HANDOFF's own sentence is that the
fade quad paints last. Completing the rule to "keyless last" gives 16 of 16.
SURVIVES. Recorded because the published claim does not say where a keyless
element goes and there is one in the archive. Separately the tie-break's reach
looks understated: 105 elements share a layer key across 12 of 16 screens, where
HANDOFF characterises the cost as "one element's blend on one screen".

WITHDRAWN, and it was mine: I filed "the runtime mix has no headroom" in red
twice, off a peak reading. Measured properly it is 43 samples at full scale in
5.9 s and 24 in 98.5 s, longest run 0.25 ms -- the disc's own confirm cue on a
transient, possibly only in the 16-bit save. Nothing changed, deliberately:
attenuating would be an unmeasured level decision of the kind I refused for the
loop point. A peak reading is not a clipping measurement.

7a6a027fc8 port: P7 -- the new-game intro plays, and the two screens it skips are named out loud
S00A has been exported since P4; what P7 needed was something to play it and a
defined place to land. Both are here, and the interesting part is the gap.

The real chain is NEW GAME -> DIFFICULTY -> SELECT DATA -> (A) on a save slot ->
~4.5 s -> S00A. DIFFICULTY and SELECT DATA are MEASURED destinations that are not
GP_TITLE builds, so no screen file exists to go to. The port jumps from NEW GAME
to the one thing in that chain it has -- and the whole design is about not
letting that read as a sequence:

  * MenuFlow.accept returns a new kind, `video`, rather than folding this into
    `blocked`, because the caller has to announce the skip and a distinct kind is
    what forces it to;
  * the runtime prints the skipped screens by name on every run;
  * flow.json carries `skipped_chain` as DATA, so what is missing lives beside
    the decision instead of inside a GDScript string.

After the movie the port returns to the title. Authored, and it has to be: the
game goes into mission 1 and gameplay is out of scope. The ~4.5 s before the
movie is left EMPTY on purpose -- GP_TITLE does carry a loading screen and 4.5 s
is about the right shape for one, which is exactly why that belongs in BLOCKED.md
and not in flow.json.

`--script`'s 20 s per-step timeout would have killed every movie run at step 1.
Raising the constant would have been wrong the other way: a movie stuck at frame
0 would then hang the job, and a job that waits is worse than one that fails. The
test is now LIVENESS -- while get_stream_position() advances the deadline moves
with it, and a stalled movie still trips the same 20 s.

Found while looking: GP_TITLE's four unnamed builds (entries 0, 1, 12, 15) are
LOADING screens -- every element in all four is pgloading_*, and LOADING is one of
the three names the decoder read out of the title part's state function. NOT
renamed here: which member of each pair is which locale is an inference, and a
name stops being questioned once written. Handed over.

One of them is a second casualty of the rest.t problem, and a worse one:
pgloading_eff00.prm rests OPAQUE BLACK at t=38, so anything drawing that screen
at its declared rest paints a black rectangle over all of it. The title's case
only dimmed a frame.

REFUTATION, attempted and SURVIVED: HANDOFF says "exactly the six screen builds
carry the black .prm quad while the six overlays do not". Counting bundles with a
full-screen black primitive gives 8 and 4 -- build_12/15 carry one too. But
theirs runs black -> held -> clear where the transition quad runs black -> clear
-> black, so read strictly as "the quad whose group is the transition" the claim
holds. Recorded anyway: there are two kinds, and the naive census over-counts.

Gate: NEW GAME -> S00A plays 93.75 s against a declared 93.9 -> title, with
98.453 s recorded off the Master bus. What that does NOT show is that S00A's own
audio is in the mix -- bed and movie were not separated in this run, and the
write-up says so.

1f1fe647f2 port: end the boot when BOTH builds have arrived, not when the plate lands
Moving the plate onto the shared clock moved the boot's exit with it: the run
quit at the overlay's settle (t=238) while build 4's own fade-in from black runs
to t=261. pteff00 is still ~7 % opaque there, so the capture came out visibly
darker than the previous one -- with nothing failing, no warning, and no line in
the log to say why. Caught only because there was an earlier capture beside it.

The boot now ends at max(view.settle_time(), overlay.settle_time()) and prints
the unit it is waiting for.

c225852fb3 port: the ring spins, the plate needs no constant, and rest.t was never the settle
Two milestones' known-wrong bits, both now answered by the RE agent, both taken.

P5 -- the focus ring. It was drawn at 0 with a comment saying so. The period is
now measured (continuous spin, eight evenly spaced autocorrelation peaks over
nine revolutions, no angle estimated anywhere) and it needs NO authored
constant: the period is the element's own declared t=120, and what the
measurement adds is only that the turn repeats rather than stopping -- which
"groups hold" could not decide, because 0 and 360 are the same pose.

`spin_period_units` is structural and narrow on purpose: two keyframes,
differing in nothing but rotation_deg, by a full 360, first timed and second
untimed. 16 of 212 elements in this export match and all 16 are focus rings,
zero false positives. That check is the point -- the measurement was taken on
ONE button of ONE screen, and a rule that caught anything else would be
extrapolating it to elements nobody watched.

Verified on the port's own render with the RE agent's own control: bit-identical
one period apart across the whole frame, 3.6/255 inside the ring's box at
quarter-period steps, and box luminance conserved to 0.027 % over eight phases
-- which is the observable they used to separate rotation from a pulse. Not
claimed: direction (no signed angle was ever measured) and phase across a focus
change (their run held focus throughout).

P3 -- the plate. Last iteration I refuted their authoring instruction and
shipped it anyway rather than pick between two of their numbers. The refutation
held and the answer came back better than either option I offered: AUTHOR
NOTHING. Both builds run on one clock started together and the plate arrives at
its own declared t=238. The 2.13 s constant is deleted.

The premise that failed was mine: rest.t IS NOT WHEN A SCREEN SETTLES. It is the
last hold keyframe before the exit. ptlogo1 stops MOVING at t=42 and then creeps
5 px and 31 alpha steps to t=251. Reading rest.t put build 4's arrival at 4.350 s
instead of 1.967 s, and the "2.51 s, which is not a landmark of anything" I sent
them is that error wearing a decimal point. 238 - 118 = 120 units = 2.000 s
against a measured 2.135 s at 28.1 fps presentation. Checked against my own
export before touching anything.

`ScreenView.settle_time()` still uses rest.t, and so the boot sequencer paces
every screen off the wrong landmark. NOT changed here: "visible arrival" is a
heuristic and getting it wrong re-paces everything. Filed, and asked for a timed
boot instead now that their oracle is live.

REFUTATION: two of their pages measure the same declared 120 units of wall clock
during a static hold and disagree by 2 % -- plate 2.135 s (28.10 fps implied),
ring 2.177 s (27.56 fps). That is seven times the plate page's own 6 ms
run-to-run agreement, and it lands on the argument that page uses to justify
itself: "the build-in is where frames are dropped; the static hold is not". Also
the ring page's band, 27.6-28.8 fps, does not contain its own measurement -- the
mean needs 27.56 and four of seven spacings are outside. Filed, not worked
around: my port uses the declared 120 units either way.

9b30fb5933 port: P3 -- the boot title gets its PRESS (A) plate, and two of the RE agent's numbers do not agree
ScreenView now draws two builds at once, which it never had to before. It is a
second ScreenView in the same SubViewport rather than a subordinate screen
inside one: each build has its own timeline, its own textures and its own hold,
which is the entire content of the finding, and Node2D siblings already paint in
tree order. `paint_order` still means what it meant -- an ordering WITHIN a
build.

The delay is authored in flow.json on the BOOT STEP, not on the `title` screen.
What was measured is the boot title; whether the plate is there when the title
is reached again -- (B) from the menu, or after the attract movie -- is not, and
hanging it on the screen would quietly claim that it is.

REFUTATION, and it is the substance of this commit: the RE agent's authoring
instruction does not reproduce the RE agent's own measurement, and the gap is
3.97 s. The instruction is "when build 4 has settled, wait 2.13 s, composite
build 2". But build 2 has a group and this port plays groups -- ptbtn00 is alpha
0x00 at t=214, still 0x00 at t=236 while it slides 10 px up, and 0xff only at
t=238, which is 3.967 s at 60 units/s. So the plate is first VISIBLE at
settle+6.10 s, while what was measured -- the glyph counter leaving 154 -- is
visibility at settle+2.13 s. Both groups starting together puts it 0.38 s BEFORE
settle; build 2 starting at settle puts it at settle+3.97 s; landing on the
measurement needs build 2's group to start 2.51 s after build 4's, which is not
a landmark of anything.

The measurement is untouched -- it is an observation of the running game and I
have no standing to doubt it. What is refuted is the step that turns it into an
authoring rule. So the port ships the instruction, prints the discrepancy on
every boot, and files the row. Same call as the BGM sub-waves: a port that
quietly picks the number that looks right destroys the evidence, because a
corrected boot looks exactly like a correct one.

Also refuted, and it was mine: BLOCKED.md has said since P2 that "no element's
alpha reverses direction anywhere in this export, so nothing pulses". ptbtn00
reverses -- 0x00 -> 0xff -> 0x00 -- and it was in the export the whole time. The
claim had been checked against the screens P2 happened to be animating. The port
still draws no pulse, because no reading of this group yields the measured
2.24 s: the whole group is 4.47 s and from its first keyframe 0.90 s.

Gate: `--boot --capture=` writes one frame of the composited end state, instead
of the 600-PNG filmstrip that was previously the only boot artifact.
`--screen=title --overlay=press_start` raises the same composite in two seconds
for anyone who does not want to sit through 137 s of Theora.

d6252481e1 port: P6 -- the menu has sound, and the BGM I "chose" was decoded all along
The three Static.slb cues and the menu bed now export to Ogg Vorbis and play.
`sylpheed_formats::media` does the assembly; nothing in port/ has heard of XMA.

Three things this milestone got wrong before it got right, all recorded in
docs/port/DECISIONS.md because the corrections are the useful part:

1. The cue offsets were a Rust `const` in the exporter. They are MEASURED, not
   decoded -- a measured value compiled into the exporter is a measurement
   wearing the costume of a decoded field, and nobody deletes it because nobody
   can see it. They are authored/audio.json now.

2. I picked BGM_001 and wrote a careful `why` calling the choice arbitrary. The
   menu's music is BGM_103, and it is in HANDOFF at 0fd8e69 -- the exact commit
   BLOCKED.md says that row was reconciled against. Not stale: wrong when
   written. I had summarised a negative without its reach, so "the TABLES cannot
   say which BGM a screen plays" became "it is not on the disc". One word of
   scope was the whole answer, and the export failed only because BGM_001
   without its .slb extension hashes to nothing. That is luck, not design.

3. The comment above the BGM sum argued for unity gain "because halving is a mix
   decision nobody made". It clipped at +1.8 dBFS. 1/n is the smallest constant
   that provably cannot clip -- the same reasoning video.rs already carried for
   its 5.1 downmix, in this repository, unread.

Unsettled and shipped as such: media::sound_bank_riffs returns THREE sub-waves
for BGM_103.slb where HANDOFF Q10's census says exactly two (the third is the
leading headerless region slb.rs emits for the voice path). The exporter sums all
three and writes a manifest warning, because which bytes belong together is the
decoders' question, not this exporter's -- and dropping one would destroy the
evidence, since a corrected export looks exactly like a correct one. Raised with
the Decoder; row in BLOCKED.md.

The gate is a null control, not a peak reading. A master-bus WAV that is
non-silent proves nothing -- the bed alone would look identical. So the same
scripted walk was run with <- in place of <v>, which fires no cue (Q5, measured),
and the difference is one 0.55 s burst at t=1.10 s and silence everywhere else.
The first attempt at that control returned bit-identical zero and I nearly filed
it as "cues never reach the bus": both runs ended at 1.115 s and the first press
lands at 1.17 s. A null result from an instrument that was not running is not a
null result.

Refutation attempt: HANDOFF Q8's three cue durations. They looked attackable --
0.133/0.172/0.169 s per packet, no shared rate -- but an XMA1 packet carries a
variable number of 512-sample frames, and the three come to 50.0/32.3/95.3
frames. Measured off the decoded Ogg: 0.533, 0.344, 1.016 s, every published
digit. SURVIVES, with its reach stated -- it confirms the assembly path and my
transcription, not the event bindings, which only an oracle can retake.

76979c799c port: P5 end to end -- and the port's title never says PRESS (A)
The P5 gate walk starts on a screen. This runs the whole objective instead, and
it is the only thing that would have found what it found:

  xvfb-run -a godot --path port -- --boot --play \
    --script=accept,down,down,down,down,accept,cancel,cancel --shots=/tmp/e2e

publisher wordmark -> developer logos -> ADV (151.9 s) -> title -> (A) -> main
menu -> navigate -> (A) -> EXTRAS -> (B) with focus restored to ptbtn05 -> (B)
-> title. 166.76 s, exit 0, nine frames. Shared as 1788003274-e68367e787d5.

THE PORT'S TITLE DOES NOT TELL THE PLAYER TO PRESS (A). The boot's last step is
`title` = GP_TITLE build 4, and build 4 has NO `PRESS (A) BUTTON` plate. P5 has
just made (A) the only way off that screen.

Not a guess about the art -- both states are captured off the running game and
differ by exactly that plate (live-title-build4-no-plate.png vs
live-title-press-a.png), and the plate is ALREADY EXPORTED as `press_start`,
build 2, sitting in export/screens/title/ unused by anything.

RECORDED, NOT FIXED, and the distinction is the point. This is P3's gate that
P5 exposed, and fixing it needs two things the port does not have:

  * WHICH state an idle post-boot title shows -- build 4 alone, build 4 with the
    plate over it, or build 4 THEN the plate after a delay -- is BEHAVIOURAL.
    The game demonstrably has both states and nothing says which follows the
    intro. The port has no oracle for a sequence; that is the Decoder's.
  * showing it means DRAWING TWO BUILDS AT ONCE, which this port has never done
    -- every mode loads exactly one screen. That is a change to ScreenView, not
    a line in flow.json, and it is not being smuggled in under a navigation
    milestone on the strength of "it looks more right".

Filed in BLOCKED.md. P5's gate is (A) into a submenu and (B) back; both work.

Two smaller things the same run found, both fixed:

  * the boot step's `why` still said "nothing takes the title's place until P5
    gives it somewhere to go". P5 has. Now says what is true: `--boot` STOPS on
    the title (a boot that ends by fading to black looks like a crash) and
    `--play` HANDS THE HELD TITLE OVER -- the stop is not a bug and the handover
    is not another boot step.
  * an empty focus printed as a line that trailed off, reading like a value had
    gone missing rather than like there is none. The title is a screen with no
    `buttons` that still takes (A), so it now prints
    "(none -- this screen has no focusable item)".

Also confirmed: entering a submenu directly (`--menu=extras`) and pressing (B)
enters the parent at its AUTHORED initial focus, not a restored one. There is no
history to restore and MenuFlow.cancel only claims a restored focus when the
stack agrees about where it is going.

1defbe0a32 port: P5 -- the menus navigate, and the focus ring is drawn wrong on purpose
P5's gate is "a human clicks through it". The artifact is a scripted walk that
proves the wiring rather than the intent -- up (wraps 01->05), five down, (A)
into EXTRAS, down, (B) back, landing on the main menu with focus RESTORED to
EXTRAS, ten PNGs one per settled step:

  xvfb-run -a godot --path port -- --menu \
    --script=up,down,down,down,down,down,accept,down,cancel --shots=/tmp/p5

--script posts InputEventAction through Input.parse_input_event so the presses
arrive at _unhandled_input exactly as a d-pad's would. Calling MenuFlow directly
would have been shorter and would have proved nothing: the wiring between a
press and the cursor is the part most likely to be broken, and a direct call is
exactly the part that skips it.

Derived vs authored, which P5 is the easiest place to blur:

  * DERIVED -- the ORDER of the items, from each screen file's `buttons`, which
    the exporter already fills from button-role elements sorted by resting Y.
  * AUTHORED -- destinations, initial focus, what (B) does, and left/right being
    a no-op. All measured off the running game (HANDOFF Q4/Q5) or chosen, none
    on the disc, all in authored/flow.json with a why.

Four of five main-menu destinations are `goto: null` with a `blocked` note. That
is a MILESTONE BOUNDARY, not an unknown -- DIFFICULTY, the save list, the lesson
list and OPTIONS were all measured and live in archives this export does not
carry. `blocked` and `none` are kept apart so nobody later "discovers" the gap.

--headless CANNOT DRAW, and the port hung instead of saying so.

Measured, not assumed: under --headless Godot's dummy renderer never emits
RenderingServer.frame_post_draw, so every capture path awaited it forever --
--capture since P1, --film since P3, --shots as of now. With stdout block-
buffered the observable behaviour was SILENCE, FOREVER, which in a loop reads as
a job still working. Isolated by `--quit` (prints, exits 0) vs `--capture` (zero
bytes, killed at 40 s). Now those three flags refuse at STARTUP naming the
xvfb-run line that works, and --script no longer waits for a frame it is not
going to photograph -- so headless walks the menus in 4.5 s as a cheap
regression check needing no X server.

REFUTATION ATTEMPT, against the Decoder's 76653ca point 2 ("the oracle confirms
the game renders the ring's rotation"). Aimed there because PROTOCOL says to aim
at a claim the port is about to build on that rests on an estimator whose own
control the Decoder reported as +/-19.8 deg. IT SURVIVES, more strongly than
claimed.

Both captures draw the SAME sprite (ptbtneff01) 240 px apart, so "is it drawn
rotated" becomes "are these two crops one image at a different angle" -- no crop
offset needed and no reference to our own renderer. 360-bin angular luminance
profile over the annulus, circularly cross-correlated. Two controls first: known
rotations 0/30/90/150/210/270/330 recovered with 0 deg error, and a ring-free
patch of the same capture peaks at 0.369, so the estimator does not manufacture
matches. Then: A vs B 134 deg (corr 0.968), sprite vs A 76 deg, sprite vs B
210 deg -- and 210-76 = 134, which nothing in the method forced.

So 0 deg is NOT A POSE THE GAME SHOWS, and screen_view.gd draws the ring at
0 deg. That is now stated in the code as known-wrong rather than suspected. The
port did NOT start spinning it: the period has two unknowns and both are the
Decoder's -- the second keyframe is untimed, and "groups hold" predicts a stop
at 360 = 0 which contradicts both captures. Two frames of one focused button a
known time apart settle it. Filed in BLOCKED.md and asked over the channel.

BLOCKED.md's staleness check was half a check. It tested whether that page is
stale relative to HANDOFF; it cannot see the other direction, and the other
direction is what happened -- 76653ca lands 27 minutes AFTER HANDOFF was last
written and answers a question HANDOFF still lists as open. Added the missing
half: `git log --oneline 0fd8e69..HEAD -- docs/re/`.

Also recorded, since the two were nearly confused: the ring's annulus centroid
lands within ~0.4 px of its design position under a ZERO crop offset, which
corroborates ORACLE-CAPTURES' "1279x675, top-left aligned" on a feature nobody
chose for the purpose. The earlier "text bands at design y + 23" is an offset
WITHIN the button sprite, not a crop offset.

9fbb352ef0 monorepo: one repository for the decoders, the port and the corpus
Merges the Godot port into the reverse-engineering repository, preserving both
histories -- 1019 commits of corpus plus the port's 31, brought in by subtree
merge and then moved into place so git can follow each file across the rename.

The reason is not tidiness. The two-repo split forced the exporter to depend on
the decoders by pinned revision, and that created a whole class of failure that
now disappears: a sha reachable only from a topic branch, orphaned by a
squash-merge, breaking a fresh checkout silently at build time. It also forced a
live read-only mount of one agent's working tree into another's container, which
is why a contract file could move mid-iteration. With a path dependency, a
decoder change and the exporter change it requires land in the same commit or
not at all.

Canary stays separate: it is a fork tracking upstream.

New structure for the long term:

  docs/game/     how the game is NAVIGATED -- menus, modals, prompts, alerts,
                 and in-game flight. Written so nobody rediscovers it. Mostly
                 open questions on purpose; the in-game tutorials are the
                 resource for the flight half.
  docs/port/MODDING.md
                 modding as a constraint on the exporter TODAY, not a later
                 feature: one logical asset in one file (the disc splits nearly
                 everything, and resolving that is the exporter's job), names a
                 person recognises, PNG/OGG/OGV/JSON only, base-and-overrides so
                 re-exporting is always safe, provenance in every file.
  data/base + data/mods
                 generated tree and drop-in overrides, both gitignored
  exchange/      transient inter-agent files, deliberately outside history
  docs/agents/   the team protocol

Both the README and the navigation doc lead with the correction that cost the
most: the oracle is the real game under Xenia Canary. Reborn's renderer is a
hypothesis under test, it has been wrong, and treating it as ground truth
propagated into three documents and both agents before a human caught it.

Scripted modding stays possible without being built: no screen name is hardcoded
in GDScript and there is no native code in port/, which is what Godot Mod Loader
needs to be able to substitute behaviour later.
