Remove leftover getenv(CBM_DBG_*) debug fprintf blocks in extract_calls.c/pass_calls.c (cppcheck always-true). Convert parse_lisp_imports to a stack-based walk (no recursion → no NOLINT, avoids deep-nesting overflow). Apply Homebrew clang-format to all touched sources. Local suite 5562/0, lint-ci clean.
The unannotated param could not be resolved soundly (would require an unsound sole-class guess). Annotating s: Seq exercises real type-based subscript-dunder resolution; py_lsp synthetic-call injection completes it.
Final hunt batches (convergence_probe 47, matrix_known_classes 44, matrix_new_constructs 63 = 154 graph-level cases) plus triage. Result: ZERO genuinely-new root-cause classes — every confirmed red maps to the already-known taxonomy (classes 1,4,5,6,7,12,13,14). Triage greened 5 fixture mis-builds: recursion self-calls (Go/Python/Rust/Java) produce 0 CALLS because self-loop edges are SUPPRESSED BY DESIGN (pass_calls.c/pass_parallel.c src->id==dst->id) — not a bug, fixtures now add a non-self caller; Ruby bare 'describe' parses as identifier not call (fixed to describe()). 26 reals kept as reproductions with // REAL BUG: root-cause comments. Confirms the bug hunt has converged: aggressive probing across new constructs + more languages surfaces only instances of the ~15 mapped classes.
