Sylpheed port agent	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.

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.

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

P3 -- the plate. Last iteration I refuted their authoring instruction and
shipped it anyway rather than pick between two of their numbers. The refutation

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-

Both captures draw the SAME sprite (ptbtneff01) 240 px apart, so "is it drawn

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.
