requirements-traceability

Create or audit requirements-to-design-to-code-to-test traceability. Builds a traceability matrix (REQ → design/ADR → implementation files → tests → evidence) and flags gaps (unimplemented requirements, untested changes, undocumented decisions). Use when you need a requirements traceability check for a PR/release, regulated/compliance work, or when requirements are drifting from implementation.
