Created systemd user timer `cognitive-memory-embed.timer` that runs hourly. Uses `claude-memory embed --if-changed` which compares memory IDs in _index.json vs _embeddings.json — skips in ~0.1s when nothing changed, full re-embed (~27s) only when memories were added or deleted. Removed embed from daily timer (cognitive-memory-daily.service) since hourly covers it. Daily timer now only runs decay, core, and symlinks. Both services need `export PATH="/home/cal/.local/bin:$PATH"` because systemd doesn't load user shell profile and `uv` lives in ~/.local/bin. Files: ~/.config/systemd/user/cognitive-memory-embed.{service,timer}.
