Trace shots against current map geometry instead of stale render depth. Preserve outline counters across volatile pixel calls and freeze gameplay on cinematic, transition and death ticks. Clamp packed HP before narrowing and match legacy archetype rules. Publish IDE saves atomically; failed saves block file switches and builds. Drain compiler output while hidden. Verify runtime/editor builds, 112 editor checks, 148 ASM checks and live preview parity. Record remaining stages in docs/STABILIZATION.md.
