The char-level streaming fuzz runs 12 seeds × 500 growing prefixes (~6000 full+cached lexes) and first trips the pre-fix boundary at seed 11 / step 257, so the workload can't shrink without gutting the guard. The work is bounded but exceeds Vitest's 5s per-test default on CI workers under parallelism, so give this one test an explicit 30s timeout instead of weakening coverage.
