Graphify — looks good

Looks safe to merge — no coupling regressions and no blocking issues, checked against the code graph (not a self-assessment).

Graphify review — findings

This PR adds Common Lisp as a supported language. It introduces a new graphify/extractors/commonlisp.py extractor (backed by tree-sitter-commonlisp), registers it in the extractor dispatch tables and language registry, and wires the .lisp/.cl/.lsp/.asd extensions into detect.py's code-extension set. Documentation in the README is updated (grammar count 36→37, new optional dependency entry, extension list) and a corresponding set of language tests is added or modified. Reviewer surface area: the new extractor module, the dispatch/registry hookups in extract.py and extractors/__init__.py, the extension additions in detect.py, README updates, and the test suite changes.

No blocking issues surfaced.

Analysis details — impact, health, verification

Impact & health

Graphify review

Impact — 1867 functions depend on the 785 functions this change touches.

Health — this change adds coupling hotspots:

  • new: extract_commonlisp() — 25 callers, 1 callees
  • new: _process_form() — 1 callers, 10 callees
  • new: _handle_def_form() — 1 callers, 6 callees
  • new: _handle_defpackage() — 1 callers, 6 callees

Verification — 1867 functions in the blast radius were not formally verified this run (proofs are advisory here).

Gate & verification

graphify gate

PASS — objectively clean (no health regressions, tests not run — proofs not run this pass (advisory)). Grounded, not self-assessed.

Advisory (not blocking):

  • verification_scope: 1702 function(s) in the blast radius were not formally verified this run
