Greg Pomerantz 16526a402a Keep-alive inactive by default: it froze the Mali display pipeline 
The 16 ms keep-alive submits from a 5th thread, racing Slint's
render/present path and the four decode workers on the same wgpu
queue, hung the phone UI for seconds (51 decodes stalled ~6 s).
System survived (no reboot) but it read as a crash. Debug knob
.gallery_keep re-enables it.

Also: jsamp one-shot permission probes (the cgroup/PSI polling
loop flooded the SELinux audit subsystem at ~100 denials/s and
ANR'd the app); cgroup/PSI probing removed (the device has the
cgroup cpu controller disabled, so quota was ruled out anyway).
Sampling at 5 ms. HANDOFF 8.8 records the full findings.

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).
