v0.2.0

What's New

Vector-ranked retrieval — All five memory types now use embedding-based semantic retrieval, replacing the previous keyword/filter approach. Recall and ranking quality improve significantly across the board.

Postgres backend — Membrane now supports Postgres as a storage backend with native embedding-based selection. Configure via env var; integration tests cover both backends.

Semantic extractor consolidation — A new pipeline consolidates and deduplicates semantically overlapping memories at extraction time, reducing noise in long-running agents.

OpenClaw client plugin (contributed by @alberthild) — First-party plugin integrating the OpenClaw client. Includes full schema validation, sealed tool parameters, and plugin test coverage.

--version flag (contributed by @yunior123) — membrane --version now works and is injectable via ldflags for reproducible builds.

Eval

The eval suite has been rewritten to benchmark Membrane against a standard RAG baseline across all five memory types. Lifecycle behaviors — retraction, reinforcement, supersession, and decay — are now tested explicitly. A CI workflow keeps README scores automatically up to date.

Fixes & Cleanup

• Sealed tool parameters against unknown properties
• Corrected memory_types schema; invalid search filters now rejected
• Added min/max bounds to limit and min_salience in tool schema
• Fixed gofmt formatting in eval binaries
• Fixed actionlint warning in CI
• Removed legacy docs directory and docs build workflow
