A klammer that reaches itself, directly or through a cycle, expanded until the C++ stack was exhausted: the process died from SIGSEGV with no message and no location. The former limit guarded only the top-level fixed-point iteration, never the descent through klammer application. A depth guard now raises a recursion error naming the klammer and where it was applied. The same loop's termination test moves from "the katom list stopped growing" to "a pass applied no klammer", since a klammer whose body expands to nothing is a reduction that adds no katoms; exceeding the round limit is now an error rather than a message followed by rendering a document with live klammers still in it. ktext --check locates every klammer application written in a document or in a klammer body and checks name existence, argument count, option names, and target coverage without applying anything, reporting all problems at once. This is possible because Klammertext has no catcodes: katom structure is fixed when a file is read, so a klammer body has a determinate shape before it is expanded. The check therefore reaches what the engine cannot -- the branch of a @cond that is not selected, and bodies a given render never enters. @cond's set of truth values is an open language question, so its meaning is unchanged here; an unrecognized predicate now warns, giving its value and location. tst/ gains recursion_test.sh (7 cases) and check_test.sh (19 cases), and this snapshot's test Makefile is generated from the shipped suite list so the two cannot drift apart.

# Runs the shell regression suites shipped with this snapshot (the list is

# Requires KLAMMERTEXT_HOME set and `ktext` on PATH (build it with `make -C com`).
