interlens.context.sliding_window_policy¶

Bases: ContextPolicy

Keep the preserved framing plus the most recent keep_last turns; drop older turns.

keep_system=True (the default) preserves the system/moderator/private_context framing regardless of the window; set it False to also let framing fall outside the window (rarely wanted). Unlike DropOldestPolicy this is a fixed-size window rather than a fit-to-budget trim, so it's predictable turn-to-turn.
