ai-memory compiles a git-versioned wiki at session end instead of retrieving over raw logs.

akitaonrails/ai-memory (1,229 stars, +184 this week, MIT, Rust, 900 commits) inverts the usual design: hooks emit sanitized lifecycle observations during a session, and the server compiles them into coherent wiki pages at session end or PreCompact, "compiled from observations at session-end, not retrieved over raw logs." Storage is a git-versioned markdown directory plus SQLite with FTS5 and embeddings, alongside immutable transcript segments. Support matrix covers 15 CLIs including Claude Code, Codex, Devin CLI, OpenCode, Cursor, Gemini CLI, Antigravity CLI, Kimi Code and VS Code Copilot via MCP, with vendor-to-vendor handoff as the explicit goal. Read it against the 0-memory-operations paper: compile-time memory is a harness property, which is exactly what that paper says it has to be.
