Greg Pomerantz d38dcd3495 Jank A/B script for the phone (scripts/jank_ab.sh) 
One-shot: install release APK, verify thread priorities (thumb-* nice 2,
slint vsync nice 0), then two 30 s user-scroll windows — real textures vs
grey 1x1 images — with SCRDBG cadence analysis (on-grid %, stalls, p95,
worst). Decisive fork: real-janky+grey-smooth -> texture/GPU path; both
janky -> base render/present path; both smooth -> priority fix worked.
Dry-run tested on the emulator (grey knob detection, priority readback).

gallery

A high-performance image gallery for Android (primary), Linux and macOS — Rust + Slint 1.18.

Status: M1 (metadata scan + DB) done. See HANDOFF.md — the development hand-off with the full plan: architecture, thumbnail pipeline, milestones M1–M7, Slint gotchas, permission flow, and performance targets. Next: M2 (thumbnail engine).

Build

./scripts/build.sh debug     # debug x86_64 APK + install on emulator
./scripts/build.sh           # release x86_64 (emulator)
./scripts/build.sh aarch64   # release aarch64 (device)
cargo run                    # desktop (Linux needs libfontconfig1 + pkg-config)

Requires: Rust (rustup), cargo-apk2, Android SDK + NDK 27 (see HANDOFF.md §3 for exact paths/env).

License

GPL-3.0 (see LICENSE). Built on Slint, used under the Slint royalty-free license for proprietary apps (see HANDOFF.md §10.4).
