Four test files and one node header carried no TRACES tag, so the requirements they verify read as implemented-but-unverified. Tagging a test is what distinguishes the two. test_calibration.cpp is AR-023; its three [report] cases verify GR-003 and are tagged separately, since the report is fitted from the same distributions but is its own requirement. test_similarity.cpp is the CI half of AR-026 — equivalence against hand-computed dot products, where throughput at scale is AR-027 and cannot run on this host. test_face_tracker.cpp is AR-007 and AR-008. Two headers described code that no longer exists. face_aligner_node.hpp still documented the RANSAC fit AR-005 replaced with an Umeyama least-squares fit over all five points — not merely out of date but the opposite of what the file does, and it reads as a rationale for discarding the landmarks AR-030 measures. test_face_tracker.cpp still described the park/revive branch AR-008 deleted, and the raw-cosine cut_revive_sim that guarded it, which AR-024 retired.
