 | 3 — lex.sx (lua + tcl) | [done] | 559b0df9 | lex.sx exports nil-safe char-class predicates + token record. lua/tokenizer.sx (7 preds) and tcl/tokenizer.sx (5 preds) collapsed into prefix-rename calls. lua 185/185, tcl 342/342, tcl-conf 3/4 — all = baseline. |
 | 4 — pratt.sx (lua + prolog) | [done] | da27958d | Extracted operator-table format + lookup only — climbing loops stay per-language because lua and prolog use opposite prec conventions. lua/parser.sx: 18-clause cond → 15-entry table. prolog/parser.sx: pl-op-find deleted, pl-op-lookup wraps pratt-op-lookup. lua 185/185, prolog 590/590 — both = baseline. |
 | 5 — ast.sx (lua + prolog) | [partial — pending real consumers] | a774cd26 | Kit + 33 self-tests shipped (10 canonical kinds, predicates, accessors). Step is "Optional" per brief; lua/prolog parsers untouched (185/185 + 590/590). Datalog-on-sx will be the natural first real consumer; lua/prolog converters can land later. |

Existing prolog/haskell engines untouched (structurally divergent — mutating-symmetric vs pure-asymmetric — would risk 746 passing tests under brief's revert-on-regression rule). Real consumer is minikraken/datalog work in flight. |
