Module summarization

Expand description

Context summarization pipeline for zeph-agent-context.

This module organises the three summarization tiers:

Deferred (deferred) — stores tool-pair summaries on message metadata and applies them lazily when context pressure rises, preserving provider cache hits.
Pruning (pruning) — evicts tool output bodies using one of the five configured strategies (Reactive, TaskAware, MIG, Subgoal, SubgoalMig).
Scheduling (scheduling) — dispatches the Soft/Hard/Proactive compaction tiers and drives non-blocking background goal/subgoal extraction.
Compaction (compaction) — LLM-based summarization that drains the oldest messages and reinserts a compact summary.

All entry points accept a crate::state::ContextSummarizationView so the logic contains no Agent<C> references and the crate does not depend on zeph-core.

Modules§

scheduling: Compaction scheduling: tiered compaction dispatch, proactive compression, and background goal/subgoal extraction.

count_deferred_summaries: Count messages that carry a pending deferred_summary.
count_unsummarized_pairs: Count tool-use/result pairs that have not yet been summarized.
find_oldest_unsummarized_pair: Find the index of the oldest unsummarized tool-use/result pair.
