+\ API conformance probes for forth — the same sections as lua.lua, in the
+\ same order; that file is the reference and carries the protocol notes.
+\
+\ PROBE traces the marker, then runs the probe word.  forth's CATCH catches a
+\ THROW, and what a binding refuses is not one — a pop past the empty stack
+\ reads memory rather than raising — so the sections whose call the reference
+\ refuses are not in this file.  Neither are the sections whose argument is a
+\ string, a float, or left out: a forth word takes what the stack holds, and
+\ the stack holds integers.  The coverage line is what says so.
+\
+\ Generated by openspec/changes/conformance-forth-probes/generate.py, whose
+\ table carries each word's stack shape as src/api/forth.c comments it.
