Replace raw strdup calls in the incremental inbound-edge snapshot with cbm_strdup so the touched path follows the repository portability wrapper convention. Add a source-safety diff guard and self-test that reject newly introduced raw strdup calls in production code without failing historical existing uses.
Validation: git diff --check; make -j8 -f Makefile.cbm build/c/test-runner; make -f Makefile.cbm lint-source-safety; CBM_ONLY_SUITE=pipeline ./build/c/test-runner; CBM_ONLY_SUITE=incremental ./build/c/test-runner.

Add a root-overridable self-test harness for scripts/check-source-safety.sh so the guard can be tested against synthetic trees without scanning the real repository.
Cover clean input, MCP/server stdout writes, unsafe string APIs, and new raw filesystem APIs in production diffs. Add a dedicated lint-source-safety target because the broader lint-no-suppress path is currently blocked by existing NOLINT audit failures before this guard can run.
Validation: bash scripts/test-source-safety.sh; bash scripts/check-source-safety.sh; git diff --check; make -f Makefile.cbm lint-source-safety.
