Once a hunt reaches `cop2vu` it stops: that group is one dispatch bit covering the whole VU macro-mode instruction set, and there was no next axis. Finding which of them miscompiles meant hand-editing the classifier and rebuilding per hypothesis. Two additions close that gap. `--rec-fallback cop2vu:<mnemonic>` selects individual macro ops by name, over a flat 256-entry id space covering all three dispatch tables (BC2 by rt, SPECIAL1 by funct, SPECIAL2 by its packed index). And a compile-time census, printed after --mkstate, lists the macro ops the run actually emitted — an op that never compiles cannot be the bug, so it turns a 100-way search into a bisect over the handful a given game really uses. On NASCAR Thunder 2002 the census reported 58 distinct ops and the bisect reached one of them in eleven runs, no rebuilds.
