The epic record said nothing was open. CG-38 is: agent-named symbols in the
tail of a large file never render, which the epic's probes cannot see because
none of them measures whether the named symbol appeared.
Also corrects a wrong claim made while investigating it. The epic was said to
have regressed its own motivating query; that comparison varied the index as
well as the engine. A controlled bisect holding the index fixed shows the
pre-epic engine rendering 12 lines and CG-36 rendering 463 — the epic strictly
improves the case, and the symbols render at neither.
