# Parameter Groups
Shared parameters reused across command roots. Groups emerge from semantic coherence — parameters that together control the same operational concern.
See [param/readme.md](../param/readme.md) for individual parameter specs and [command/readme.md](../command/readme.md) for per-command usage.
### Responsibility Table
| `01_output_control.md` | Output Control — show_stat, show_tokens, show_tree toggles |
| `02_project_scope.md` | Project Scope — project:: identifier scoping |
| `03_session_identification.md` | Session Identification — session_id:: direct access |
| `04_session_filter.md` | Session Filter — session/agent/min_entries listing filters |
| `05_scope_configuration.md` | Scope Configuration — scope:: and path:: discovery boundary |
