use_hint/usehint were unit-global first-leaf-match: two directory- packages exporting the same fn leaf, each imported by a different module aliasing the same bareword, mis-routed every qualified call to whichever use was collected first. Identically wrong on both stages (byte-id-green #263-class). Key the hint on (owner-module, alias) and prefer cur_mod, mirroring the checker's use_path curmod-preference (55f54fb). 989_m1usehint_run: two same-leaf pick() across a.math/b.math, each module's call routes to its own import (111/222) + cs.s==ww.s.
