 Three read-only lens agents in `parallel()`; the orchestrator synthesizes the ≤400-word Project Brief and discards the raw returns.
 
 **A1 — Code/asset graph (read-only).**
-> Map the code surface relevant to `{goal}`. Prefer serena `find_symbol`/`find_referencing_symbols`; if serena's C# LSP stalls on the Unity solution, use `Glob`/`Grep` on `Assets/_Project/**/*.cs` + `**/*.asmdef`. Identify the existing components/systems/bakers touching `{surface}`, the asmdef each lives in (Simulation / Client / Server / Authoring), and any `*Math.cs` helper or system you'd otherwise duplicate. `manage_scene get_hierarchy` for relevant subscenes. Return a terse symbol/asmdef map (names + paths), not file dumps.
