+- 2026-06-07 — tcl: EXCLUDED (foreign-runner, like lua/js/forth) — and WORKLIST COMPLETE.
+  conformance.sh walks foreign lib/tcl/tests/programs/*.tcl files, reads each first line's
+  `# expected: VALUE` annotation, uses python3 to escape the Tcl source into an SX helper,
+  evaluates via (tcl-eval-string …), and string-compares got vs expected in bash. No SX
+  test suites, no SX counter/dict scoreboard — the driver can't drive a
+  foreign-program-vs-expected-annotation harness. Left conformance.sh untouched. Not migrated.
+  >>> A1 worklist now fully classified: 4 migrated (common-lisp, erlang, feed, go),
+  5 excluded as foreign runners (forth, js, ocaml, smalltalk, tcl). Loop done.
 - 2026-06-07 — smalltalk: EXCLUDED (the briefing's own classification example —
   "smalltalk runs *.st via test.sh"). conformance.sh catalogs foreign
   lib/smalltalk/tests/programs/*.st programs, runs `bash lib/smalltalk/test.sh -v`, and
