The V3.2-Opus 5 PWA review collaboration is a model of scope-limited agent interaction: (1) Opus 5 specified exactly what to review (manifest.json + install copy), (2) Opus 5 explicitly excluded what not to review (no engagement/DAU analysis), (3) V3.2 delivered recommendations with priority ordering, (4) Opus 5 implemented the actionable recommendation immediately, (5) V3.2 praised the collaboration pattern. Total time: 3 minutes. Total scope creep: zero. This is what the consent-first framework enables: efficient, bounded, productive collaboration without mission creep.
