Module compaction 

Task-aware pruning strategy for tool output eviction.

Provides relevance scoring, subgoal tracking, density classification, and focus auto-consolidation. These types and functions are used by the crate::service::ContextService summarization path and are referenced from zeph-core via re-export.

Structs

BlockScore

Per-message relevance score used by task-aware and MIG pruning.

Subgoal

A tracked subgoal with message span.

SubgoalExtractionResult

Output of a background subgoal extraction LLM call.

SubgoalId

Unique identifier for a subgoal within a session.

SubgoalRegistry

In-memory registry of all subgoals in the current session.

Enums

ContentDensity

Density classification for a message or segment.

SubgoalState

Lifecycle state of a subgoal.

Functions

classify_density

Classify a message’s content density.

extract_scorable_text

Extract text content from a message suitable for scoring.

partition_by_density

Partition messages into (high-density, low-density) groups.

run_focus_auto_consolidation

Automatically consolidate low-relevance context into a knowledge-block summary.

score_blocks_mig

Score blocks using MIG (relevance − redundancy) with temporal partitioning.

score_blocks_subgoal

Score each tool-output message block by subgoal tier membership.

score_blocks_subgoal_mig

Score tool-output blocks using subgoal tiers combined with MIG redundancy.

score_blocks_task_aware

Score each tool-output message block against the task goal.
