Phase 1 — persona + persistent memory chat loop: - lyra/persona.py + personas/lyra.md: editable identity/voice (friend-first, honest, never invents poker math) - lyra/chat.py: turn loop assembling persona + cross-session recall + recent context, persisting both sides to SQLite - lyra/session.py, lyra/__main__.py: session lifecycle + `lyra` REPL Phase 1.25 — reuse the old web UI: - vendored the prior single-page UI into lyra/web/static, repointed to same-origin - lyra/web/server.py (FastAPI): serves the UI and backs its endpoint contract (/v1/chat/completions, session CRUD, health, inert thinking-stream) with the new chat loop + memory; SQLite stays the single source of truth - `lyra-web` console script Local backends — test for free, no OpenAI key: - llm.embed routes via EMBED_BACKEND (cloud=OpenAI, local=Ollama /api/embed) - simplified UI backend selector to Local (Ollama) / Cloud (OpenAI), default local - memory connection opened check_same_thread=False for the threaded server Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
