- Add CLAUDE_OPUS_4_7_CONFIG and register it in ALL_MODEL_CONFIGS
- Set Opus 4.7 as default for firstParty in getDefaultOpusModel() (3P stays on 4.6 until rollout)
- Fix sonnet[1m] → 404 bug: query.ts was passing raw alias to API without resolving via parseUserSpecifiedModel
- Add opus-4-7 to modelSupportsAdaptiveThinking so it uses { type: 'adaptive' } not { type: 'enabled' }
- Fix duplicate opus47 case and wrong opus46[1m] fallthrough in getPublicModelDisplayName switch
- Update user-facing display strings (picker labels, plan mode description) to reference Opus 4.7
- Add 3P fallback suggestion chain for opus-4-7 → opus-4-6 in validateModel
