ORCH

New Features

• Grok adapter — first-class grok adapter backed by the Grok CLI. Supports headless execution, model selection, reasoning effort, max turns, system prompt override, tool/error event mapping, streaming text aggregation, doctor, init, TUI wizard, model tiers, docs, landing assets, and smoke/e2e coverage.
• Antigravity adapter — first-class antigravity adapter backed by Google Antigravity CLI (agy). Supports headless prompt execution, model selection, permission bypass for autonomous runs, stdout streaming, doctor, init, TUI wizard, model tiers, docs, landing assets, and smoke/e2e coverage.
• Runtime model discovery in TUI — model choices now load from adapter CLIs where available (grok models, agy models, opencode models, pi --list-models) with curated fallbacks for unavailable or non-listing CLIs. Agent creation, edit flows, and Agent Shop templates all use the same model catalog path.

Bug Fixes

• Targeted orch run <task-id> no longer dispatches unrelated todo tasks — running a specific task now keeps ownership of that request instead of reactive-dispatching other queued tasks after the requested task completes.

Refactoring

• Model catalog source of truth — moved TUI model fallback options out of wizard config into src/infrastructure/models/model-discovery.ts, so adapter model lists are centralized and guarded by AdapterKind.
• Adapter type safety — model option lookup now uses the existing isAdapterKind guard instead of string casts.

Tests

• Added unit coverage for Grok and Antigravity adapters.
• Added integration coverage for the new adapters.
• Added model discovery parser and TUI wizard catalog tests.
• Extended model tier, onboarding, and smoke coverage for grok and antigravity.
