Memory Layer v1.0.0

First stable release of Memory Layer: local-first, project-scoped memory for coding agents.

Highlights

• Self-maintaining memory (new) — memories earn an activation score through real usage (retrievals, answer citations), activation spreads to linked memories and decays over time, and hot memories are re-validated against project evidence (sources, provenance, git history) by an opt-in LLM pipeline. Weak evidence never rewrites content — it flags the memory for review. New commands: memory scores, memory validate, memory review; new [reinforcement] config section (scoring on by default, validation opt-in and dry-run first).
• Hybrid retrieval (full-text + embeddings + code graph) with ranking diagnostics, provenance verification, and replacement-proposal curation.
• Terminal UI, browser UI with 3D graph explorer, watchers, loop automations, and a read-only MCP server.

Install

Debian/Ubuntu:

sudo dpkg -i memory-layer_1.0.0_amd64.deb

macOS:

brew tap 3vilM33pl3/memory https://github.com/3vilM33pl3/memory
brew install 3vilM33pl3/memory/memory-layer

Requires PostgreSQL with pgvector. Full instructions and upgrade notes: see the documentation site or docs/user/.

Known issues

• Four loop_repository integration tests fail on PostgreSQL 17 (FOR UPDATE on the nullable side of an outer join); loop approval flows are unaffected in normal use but this is tracked for a point release.
• Windows packaging is prepared but not yet released.
