Partnership Compatibility (two-person)

Structured two-person PARTNERSHIP reading (taxonomy partner-1) for a co-founder, business, romantic or friendship bond — extends work-1. Embeds the collaboration core (role pairing, decision pacing, Wu Xing day-master relation, four dimensions) and adds: zodiacRelation (生肖/year-branch 三合/六合/六冲/六害), dayBranchRelation (day-branch/spouse-palace 合/冲, weighted for romance), elementComplement (does each supply the element the other lacks?), leadershipBalance (who leads vs anchors), frictionAxes[] (the 冲/害/剋 axes to watch + repair guidance), a relation-typed synthesis, and a symbolic partnerFit explicitly labelled 'not a matchmaking verdict'. The relation param (business|cofounder|romance|friendship|general) weights which layers matter. The embedded collaboration core carries hdTimeAssumption when a birth time is omitted (see /compatibility/work). Symmetric in the two people, deterministic, structured-only. A shared conversation aid — per the API terms never a screening, ranking or matchmaking verdict.
