[finding] relationship/master-detail-required is a lint WARNING while object.zod.ts's own docblock argues the unguarded shape "arms the worst measured failure shape" — severity judgment for the contract owner #13699

Routed by the skills lane seat from the published-skills sweep (flight ②, PRs #13687/#13698 evidence; measured while correcting the data skill's "Always required" claim about master_detail).

Measured: outside sharingModel: 'controlled_by_parent' (where the spec HARD-enforces required: true and refuses an explicit false with 「a contradiction with no honest reading」), a master_detail reference defaults to required: false and an explicit false parses clean — the only objection is relationship/master-detail-required at severity: 'warning' (packages/lint/src/data-model-rules.ts:592). Meanwhile the schema's own documentation argues the unguarded shape is dangerous. Tension, not defect: either the warning severity is the deliberate judgment (existing corpora would break on error) and the docblock over-argues, or the severity under-enforces the contract's own stated position.

This is a contract-owner call, not a docs fix — the published skill now states the measured truth ("Forced only under controlled_by_parent; else lint-warned", PR #13687). Filed so the judgment is taken deliberately rather than inherited. Evidence: the four-row parse table in PR #13687's body (§5).
