From 3ecc48fdf67ba0762a6c9d45adb652f15fc1289a Mon Sep 17 00:00:00 2001 From: can1357 Date: Sat, 30 May 2026 08:07:03 +0200 Subject: [PATCH] feat(memory): added Mnemosyne local SQLite memory backend - Introduced `@oh-my-pi/pi-mnemosyne` workspace package with BeamMemory, recall/retain, FTS, and optional fastembed ONNX embeddings. - Wired `memory.backend = "mnemosyne"` into the coding-agent settings schema and backend resolver. - Added `MnemosyneSessionState` for per-session auto-recall on first turn and auto-retain after completed turns. - Documented configuration, environment variables, and operational notes in `docs/mnemosyne-memory-backend.md`. --- bun.lock | 118 +- docs/mnemosyne-memory-backend.md | 135 +++ package.json | 1 + packages/coding-agent/package.json | 1 +
