Direct port of research/tracing-knowledge-lineages (obra/superpowers-skills, not yet vendored). Distinct from the traceability skill (that's forward spec→ADR→commit linkage; this is backward "why does X exist, was Y tried before and abandoned, is a 'new' idea actually a revival").

Techniques to port: decision archaeology (search docs/adr, git log --all --grep, ask the author), failed-attempt analysis (don't assume a past failure means the approach is flawed — trace context that may no longer apply), revival detection, paradigm-shift mapping. Full SKILL.md content already fetched during research — reuse it, adapt phrasing away from obra's generic "your human partner" tone to this workspace's conventions.
