T1 — one octave, hands separate (shown in its teach state: the terrain shows on the item's first encounter only, the F6 convention — graded reps are from memory). The dots carry the sourced fingering (1-2-3 · 1-2-3-4-5, thumb under at E). B major's five black keys make the terrain the lesson. Top note once at the turnaround.

T2 — two octaves, hands separate. Blank keyboard on graded reps; played keys light as they land (shown mid-run). Wrong notes log substitution tagged scale-degree:N + key:A♭.

T3 — hands together, parallel. Adds the hand-alignment stat (onset delta per degree, as F6 T3); the asymmetric thumb-crossings (different degrees per hand) are exactly where misalignment shows.

T4 — tempo gates, hands separate. Same screen, stricter clock (v0 anchor ♪=80, tunable — the metronome shows the gate). Evenness still graded — speed bought with unevenness doesn't pass.

T5 — four octaves at the RCM upper anchor (♪=104, HT). The full technique-exam scale. The viewport is beat-indexed to the expected path — it leads the hand, never chases played keys.

Scale types are config, not schema. Toggling "harmonic minor" in drill scope reveals its items with FSRS state intact (cards created lazily); chromatic, natural/melodic minor, and later modes or pentatonics arrive the same way — each type is a data entry (interval pattern + sourced fingering + scope defaults). Same grading, plus type-specific tags (the ♯7 here).

Results. F6's results anatomy with scale semantics: the late onsets cluster at descending crossings — evenness is where MIDI sees fingering quality. Feeds the same per-key evidence as F4/F6 latencies (three legs of key:X diagnosis).
