+# Particle shader lifetime reproducer
+
+Independent Godot project: no game assets, autoloads, GDExtension, network,
+EffectPlayer, or particles emitter. Eight short-lived ParticleProcessMaterials
+cycle through three emission shapes. Weak references must all be dead before
+exit; a RenderingServer synchronization also runs before quitting.
+
+Export this project with the installed macOS template using `--export-release`
+and `--export-debug` into separate directories under the repository's `build/`.
+Run each exported executable and preserve both stdout and stderr until process
+exit. A run is clean only if `ISOLATED_PARTICLE_EXIT alive=0` is present and no
+shader/RID error follows. The success marker alone is not a clean-exit verdict.
+
+2026-09-10, Godot 4.7.1 official, Apple M4/Metal:
+
+- Release: zero surviving materials, three ParticlesShaderRD/Shader RID leaks.
+- Debug: zero surviving materials, no shader/RID leak.
+
+Logs: `build/rendering/particle-isolated-release.log` and
+`build/rendering/particle-isolated-debug.log`. Path overrides (`--main-pack`,
+external `--script`) are not supported by the installed release template;
+export a standalone app instead. This project contains no copyrighted artwork
+and may be used as a minimal upstream reproduction if separately authorized.
+
+2026-09-11: an unmodified same-revision arm64 release build using
+`debug_symbols=yes optimize=speed lto=none vulkan=no` exits cleanly in this
+project and in two complete game package checks. Rebuild it with
+`bash script/build_macos_release_engine.sh arm64` from the repository root.
+This is a verified alternative build path, not proof of a specific compiler
+bug or a source fix to the installed official template. Intel and Vulkan are
+outside this result.
