 ## Notes
 
+- Related: G-070 (pure-Tcl tclparser fallback; activated 2026-08-02) - directly
+  supplies this goal's candidate scanning basis without the native-binary
+  coupling: the tclparser_tcl stub this file cites becomes a working pure-Tcl
+  'parse' implementation, so the scan can run inside build tooling on any tclsh.
 - Interacts with G-005/G-006 (how the c-only tclparser binary is provisioned if
   chosen) and G-018 (the spectrum of executable flavours).
 - G-115 relationship (recorded 2026-07-24; G-115 achieved 2026-07-31 - see

 # G-070 Pure-Tcl tclparser: parse-command API fallback with behavioural parity against the C library
 
-Status: proposed
+Status: active
 Scope: src/modules/punk/lib-999999.0a1.0.tm (tclparser_tcl stub + dispatch; new module if size warrants - decided in the work); src/tests/modules/punk/lib/ (parity + fallback suites); external fork repo c:/repo/jn/tclparser_punk (read-only reference snapshots + the zig-built parser dll oracle - G-154, achieved - see goals/archive/G-154-tclparser-punk-zig-build.md)
 Goal: punk::lib's script-analysis machinery (tclword_to_scriptlist and the dependent analysis paths) runs on runtimes without the tclparser C binary, via a pure-Tcl implementation of the tclparser 'parse' command API covering at least the subcommands and token shapes punk::lib consumes - with behavioural parity verified against the C library rather than assumed, and the C parser still preferred where present (performance).
 Acceptance: the punk::lib tclparser_tcl error stub is replaced by a working pure-Tcl implementation of the 'parse' subcommands punk::lib currently uses ('parse command' at minimum; the full covered set enumerated in this file during the work), returning the same parse-tree shapes (ranges, token types, expansion handling) the C library returns for those calls; a parity testsuite compares pure-Tcl output against the C tclparser across a recorded probe corpus (representative punkshell module scripts plus edge cases: {*} expansion, comments, backslash-newline continuation, nested command substitution, braces/quotes in words) - parity tests capability-gated on the binary, pure-Tcl-only tests running everywhere; a documented punk::lib analysis entry point (e.g. tclword_to_scriptlist) demonstrably works under a plain tclsh with no parser binary on the package path; dispatch prefers the C parser when available with the fallback engaging automatically otherwise; the reference source consulted (the tclparser_punk fork repo - snapshot and checkin/commit identity per its src/reference provenance table) is recorded in this file.
