Notes

• All 12 targets (including 4 beyond the original expected set: dim_extremes, limits_boundaries, stride_extremes, yuv_planes) were fuzzed for 600 s each in parallel.
• limits_boundaries triggered an OOM (oom-295aeb3c0ad753d8dd6830b91eabcb5ada70e8e5, 364 bytes) during the run. Minimized to 347 bytes via cargo fuzz tmin. The fuzz_regression test suite runs the seed without panicking, suggesting the underlying allocation issue may already be fixed or the OOM does not reproduce as a panic in the stable test harness.
• No other crashes, OOMs, leaks, or timeouts were found across the remaining 11 targets.
