Build-order plan (sub-phases 3a–3k) with per-sub-phase scope, exit gates, and written DA gates, modelled on docs/plans/20260520-adr-0032-phase-2.md. Centrepiece is the cross-cut verification matrix scaffold (~75 rows) grouped by ADR-0033 section (statement shapes, dispatch, RETURNING, shortid, cascade, diagnostics, UPSERT, inherited Phase-2 diagnostics, ambient assistance, engine-neutrality, persistence, OOS rejections), to be filled in during 3k. Carries the handoff-29 §4 process pins into the relevant sections: DA critiques listed before verdict, no silent out-of-scope classification, and matrix attribution requiring SQL-input tests for SQL claims. Records four open questions to escalate before code starts (shortid SELECT row-source path, R1 mechanism fallback, cascade pre-count construction, UPSERT catalog wording).
