Crate codemem_engine 

codemem-engine: Domain logic engine for the Codemem memory system.

This crate contains all business logic, orchestration, and domain operations:

• index — ast-grep based code indexing, symbol extraction, reference resolution
• hooks — Lifecycle hook handlers (PostToolUse, SessionStart, Stop)
• watch — Real-time file watching with debouncing and .gitignore support
• bm25 — Okapi BM25 scoring with code-aware tokenization
• scoring — 9-component hybrid scoring for memory recall
• patterns — Cross-session pattern detection
• compress — Optional LLM-powered observation compression
• metrics — Operational metrics collection

Modules

analysis

Analysis domain logic: impact-aware recall, decision chains, session checkpoints.

bm25

BM25 scoring module for code-aware text ranking.

compress

LLM-powered observation compression for Codemem.

consolidation

Consolidation logic for the Codemem memory engine.

enrichment

Enrichment logic: store_insight, git history, security, performance, complexity, architecture, test mapping, API surface, doc coverage, change impact, code smells, hot+complex correlation, blame/ownership, enhanced security scanning, and quality stratification.

hooks

Hooks module: PostToolUse hook handler for passive capture from AI coding assistants.

index

Code indexing engine: ast-grep based code parsing, symbol extraction, reference resolution, and incremental indexing.

metrics

In-memory metrics collector for operational metrics.

patterns

Cross-session pattern detection for Codemem.

persistence

Graph persistence: persist indexing results (file/package/symbol/chunk nodes, edges, embeddings, compaction) into the storage and graph backends.

recall

Memory recall with hybrid scoring.

scoring

Hybrid scoring for memory recall.

search

Code search and summary tree domain logic.

watch

Watch module: Real-time file watcher for Codemem.

Structs

CodememEngine

Core domain engine holding all backends and domain state.

IndexCache

Cached code-index results for structural queries.

IndexEnrichResult

Combined result from index_and_enrich.

SessionContext

Session context synthesized at session start.

SplitPart

A part descriptor for split_memory().
