Claude (auto-RE) eac92c3e44 re(flight): withdraw the roll result — the probe was measuring pitch as much as roll
Re-running roll with 5 s settles and in-run clock brackets:

  this run's clock: TIME 00:34.93 -> 00:45.97 = 11.04 s game in 7.98 s wall = 1.383
  min speed: 90.6 deg/wall-s /1.383 -> 65.5 deg/game-s  (AV_Roll_Min 200)
  max speed: 59.1            /1.383 -> 42.7             (AV_Roll_Max 125)

The corrected numbers are within a few per cent of the PITCH run's 67.8 and 40.9 —
two different stick axes cannot produce the same rates, so the probe is not
separating them. Cause: watching a non-forward matrix row sees any rotation that
moves that row, and pitch moves it as much as roll. The correct measure is rotation
ABOUT the forward axis (project the row onto the plane perpendicular to forward and
track that angle).

So "roll shows no speed dependence, unlike pitch" is withdrawn: it rested on 2 s
settles and a row that mixes axes, and the two runs disagree with each other
(144/150 then, 90.6/59.1 now). AV_Roll_{Min,Max} are not confirmed and the axis
question is open.

The clock ratio is now measured three times in three flights: 1.260, 1.311, 1.383 —
a property of the moment, not the machine, so every rate probe must bracket its own
phases.

Runtime-capture harness (sylph-re container)

Screenshot-driven scripts for reading the running retail game's menus under Xenia Canary + lavapipe, headless. They assume the container helpers screenshot, vgamepad, pad are on $PATH and HOME=/sylph-home/re.

Script What it does
skip_intro.sh Boot → main menu, unattended. Taps A only while the intro movie is actually playing (frame-to-frame RMSE), then once at the PRESS Ⓐ BUTTON title. Static logo screens are left alone, so a stray tap can never land on NEW GAME.
wait_title.sh Older variant: wait for the title (green Ⓐ glyph at px 625,618) and tap A. Superseded by skip_intro.sh.
step.sh One Arsenal navigation step (down/up/next/prev/none) + a compact capture: weapon list stacked over the DATA SHEET.
sweep.sh Walk a whole weapon-type list, capturing only rows that show a DATA SHEET — locked rows (a "Conditions to Develop" panel) are detected by the brightness of the Range Class label box and skipped.
type.sh Change weapon-type tab N times (RB) and report the header strip.
hp.sh / cyc.sh Hangar hard-point carousel: cyc.sh steps it (d-pad down, not left/right) and captures the Name + DATA SHEET.

Input timing under lavapipe: the game polls input at its own low frame rate, so a 60 ms d-pad tap is dropped roughly half the time. 200 ms is reliable; 300 ms starts to auto-repeat (two rows per press).

Findings produced with these: docs/re/weapon-datasheet-runtime.md.

Guest-memory tools (no screenshots)

Script What it does
gmem.py Read the live guest address space out of /dev/shm/xenia_memory_* (Xenia's backing file), addressed by guest VA. find / read / words.
weapon_runtime.py Solve the Weapon/Shell struct layouts against the disc records and read the fields the disc defaults.
unit_discover.py Find which runtime class carries a set of ID strings, assuming no vtable: tallies the word at pointer_site - k across distinct IDs.
unit_runtime.py Same solver for the unit\UN_*.tbl definition objects (vtable 0x820af844). Unions several snapshots — unit definitions are per-stage.
schema_order.py Merge a sub-record's field-declaration order across all tables (topological sort); the layout check that pins fields no table ever values.
order_check.py Test offset = base + 4*index for one table's sub-record against solver output.
grab_tutorial.sh Cold-boot Canary, walk to the Nth TUTORIAL entry, wait for the stage load, snapshot guest RAM. One emulator per capture — backing out of a loaded mission wedges it.

Snapshot first — cp --sparse=always /dev/shm/xenia_memory_* snap.bin (~2 s) — and point $GMEM_FILE at the copy; the running emulator pegs every core under lavapipe.
