The compacted history keeps the system prompt and the most recent turns intact (KV-cache stability) and rewrites the middle. The summary is written by the turn's own model unless `[context] summarizer_model` (`OPENHUMAN_CONTEXT_SUMMARIZER_MODEL`) names another; that model is called on the turn's provider route, with the same credentials and endpoint (`inference/turn_models.rs`). Each turn logs its choice at debug as `[context_compression] summarizer model= source=config|turn`. A failed summary falls back to a deterministic trim, not to the turn's model. ### Oversized tool results: the summarizer detour From f8cd6e29e3de26d641518227ca8c7657ac2ff1a0 Mon Sep 17 00:00:00 2001 From: Steven Enamakel Date: Wed, 28 Oct 2026 04:01:09 +0300 Subject: [PATCH 37/92] test(inference): serialize summarizer pinning test with inference guard Acquire the shared async inference test guard in the summarizer pinning test so it no longer races other tests that mutate global inference state.

From 6a46ecdf9cdefc065069f05a2707eb61ce950a73 Mon Sep 17 00:00:00 2001 From: Steven Enamakel Date: Wed, 28 Oct 2026 05:42:49 +0300 Subject: [PATCH 89/92] docs(context): document ContextSettings and out-of-turn compaction The context README now describes ContextSettings as the whole [context] table, covering the summarizer tool rendering and max output token options alongside the flattened TinyAgents ContextConfig. A new section explains how compact_history and compact_bound_history fold a thread's history outside a model turn and seal the head generation.
