dsh-compaction-policy

Main output and summary configuration remain separate

The global entry has no basic field, including under config.policy. Each engine keeps its original Basic configuration: summary provider/model, summary output budget, reasoning behavior, automatic enablement, and stock/manual/overflow settings. Configure those at the engine's existing Basic row, not in the global plugin.

Where upstream defaults are used, the 65,536-token summary cap stays intact. Policy headroom 0 does not set the summary cap to zero. The main request's output cap and thinking settings also remain unchanged. Basic's auto: false retains its native semantics: automatic pressure and overflow listeners are off, while manual /compact remains available.
