enricobuehlerandClaude Fable 5	957cf7781c	feat(apple): a Pencil near the glass pins the panel at the link ceiling ... UIKit delivers Pencil events at the PANEL's cadence, and the deadline link's rate hint pins the panel to the stream rate (min = preferred = stream Hz, deliberately — the anti-idle-stall floor). Net effect: a 60 fps stream on a 120 Hz iPad silently halved pencil sampling, 8.3 → 16.7 ms per event batch — exactly the workload (drawing) that feels it most. FrameRateHint gains a boost that lifts min/preferred to the range ceiling while a Pencil is in range (hover or contact): PencilStream surfaces proximity transitions from its emit() choke point, the view controller debounces release by 2 s (edge-of-canvas hover flicker must not thrash the link), and Stage2Pipeline/SessionPresenter stage it like the rate hint — applied from the link's own thread, no-op under arrival/glass pacing. Presents still pace at stream rate (extra updates vend into the newest-wins stash), so the cost is empty link wakes scoped to proximity. pf.present logs engage/release for on-glass verification.

enricobuehlerandClaude Fable 5	c002ca8746	fix(clients): pen batches split at the wire cap and the heartbeat survives tracking mode ... Three drawing-path defects on the pen clients: - The Apple in-range heartbeat was re-armed on every emit (~120 run-loop mutations/s during a stroke) and lived in .default run-loop mode only — a tracking-mode excursion >200 ms with a stationary pen crossed the host's force-release failsafe and dropped the held stroke. Now one long-lived 50 ms timer in .common mode, resending only after ≥50 ms of send silence. - Both clients TRUNCATED an over-8-sample coalesced run instead of splitting it into consecutive batches (the send_pen contract): Apple suffix(8) dropped the oldest samples, the Android JNI clamped count. An over-cap run means the UI thread hitched — exactly when dropping stroke geometry hurts most. Apple splits in emit(); the Android JNI loops send_pen over ≤8-sample chunks (Kotlin's per-emit ceiling is now 64 = a >250 ms stall). - The iOS letterbox mapper did a lock+FFI currentMode() read per coalesced sample on the main thread, contending the ABI lock the batch send takes next — now a 250 ms TTL cache (mid-stream requestMode still tracked).

enricobuehlerandClaude Fable 5	c8aa3ed48b	feat(apple/ios): pen P4 — Apple Pencil (Pro) capture onto the stylus plane ... The flagship leg of design/pen-tablet-input.md §7: against a HOST_CAP_PEN host the Pencil splits out of the finger path (independent of touch-input mode) into PencilStream — state-full samples with force→pressure, altitude→polar tilt, azimuth (+90° to the wire's north-clockwise convention), Pencil Pro rollAngle→ barrel roll (17.5+), coalesced touches batched ≤8/send for full 240Hz fidelity, and Pencil hover (zOffset>0 distinguishes it from trackpad hover) as in-range samples with distance. Squeeze holds barrel 1, double-tap clicks barrel 2 (the Pencil has no hardware buttons/eraser — these are how host apps get those affordances). Implements the ≤100ms heartbeat wire contract (80ms timer) so a stationary held stroke survives the host's 200ms dead-client failsafe. Toward a pen-less host nothing changes (Pencil stays a finger). Also fixes hostSupportsCursor testing the STALE 0x04 bit — HOST_CAP_CURSOR moved to 0x08 when TEXT_INPUT claimed 0x04; the old test would mistake a text-input host (e.g. Windows) for a cursor grant and double-render the pointer.
