Problem

The zeph_session_summaries Qdrant collection has 0 points across all sessions, meaning session summaries are never available for cross-session semantic recall.

Observed behavior

• zeph_session_summaries collection: 0 points (verified via Qdrant REST API)
• SQLite summaries table: has rows (summarization fires and writes to SQLite)
• Cross-session context recall (inject_cross_session_context) likely returns nothing because Qdrant has no embeddings

Expected behavior

When a session summary is created (LLM-based summarization after threshold):

1. Summary text stored in SQLite summaries table ✓ (works)
2. Summary embedded and upserted into zeph_session_summaries Qdrant collection ✗ (missing)
3. On next session, fetch_cross_session() retrieves semantically relevant past summaries

Root cause hypothesis

The SemanticMemory::save_summary() method either:

• Does not upsert to Qdrant after writing to SQLite, or
• Is never called from the summarization path in context/assembly.rs

Impact

The agent has no persistent memory of what happened in previous sessions. Every session starts from scratch even though summaries are being generated and stored in SQLite. Cross-session recall is effectively disabled.

Steps to reproduce

1. Run a session with summarization threshold configured (e.g. 6 messages)
2. Have >6 turns so summarization fires
3. Restart session
4. Check zeph_session_summaries point count — still 0
5. Ask about something discussed in the previous session — agent has no recall
