type-two e5df63128a Lane B S16 pool: the frame-determinism bound is pinned — and it is 66.7 ms, not 83 ... ROADMAP carried '>83 ms determinism bound (documented, un-tested)'. Measured: the spiral guard fires whenever a step() consumes MAX_SUBSTEPS, dropping even a legal sub-SIM_DT residual — so the unconditionally-lossless bound is (MAX_SUBSTEPS-1)*SIM_DT = 66.7 ms; 67-83 ms may drop up to one SIM_DT by accumulator phase; >=83 ms always drops. Pinned AS MEASURED (no retune): frames <=66 ms converge on the fixed trace at equal sim clocks with zero wall time lost; one 120 ms hitch drops exactly its overflow (36.7 ms). Mutations red-then-green: MAX_SUBSTEPS shrunk (6 s went missing); guard deleted (deficit 3 ms vs expected 37). Test header is the documented waiver.
