From b55d2c9ff2a62ab40b93adaf826f482aa2404c68 Mon Sep 17 00:00:00 2001 From: Millsy <231802394+millsydotdev@users.noreply.github.com> Date: Tue, 30 Jun 2026 22:47:13 +0100 Subject: [PATCH 01/15] =?UTF-8?q?=EF=BB=BFfeat(runtime):=20Wave=2017.2=20?= =?UTF-8?q?=E2=80=94=20suspension=20compression,=20SDK=20panic=20eliminati?= =?UTF-8?q?on,=20asset=20hardening?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Complete three runtime integrity tasks: Task 1 — Suspension system completion: - Zstd snapshot compression with magic-byte detection for backward compat - Performance benchmark test verifies <500ms suspend, <1000ms resume targets - 3 new regression tests (compressed roundtrip, size comparison, perf) Task 2 — SDK panic elimination: - Removed 5 expect("storage lock") calls via mutex recovery helper - Removed 3 expect("rng lock") calls via mutex recovery helper - All SDK functions now recover gracefully from mutex poison Task 3 — Asset pipeline hardening: - Replaced expect("texture_loader lock") with mutex recovery - Replaced 12 expect("cache lock") calls with recovery helpers - Added lock_entries/lock_id_map helpers for consistent mutex handling All 79 tests pass. cargo fmt, clippy -D warnings clean. --- Cargo.toml | 1 + crates/vibege-asset/Cargo.toml | 19 + crates/vibege-asset/src/cache.rs | 319 +++++
