lib/tests/run-doc-behavioral.md — in-vivo whole-chain check (twin of run-behavioral.md for memory). Scenario A: doc-syncer patches a public doc, the include commits it surgically with dangling code present (coupled + surgical). Scenario B: a forbidden .claude/ path in PATCHED_FILES → helper refuses (rc 4), nothing half-committed, offender named (fail-closed + loud). Complements the 28-assertion deterministic suite (run-doc-commit.sh).
