Summary

When agents.defaults.memorySearch.extraPaths is configured, every agent independently indexes and embeds all files in those paths. For a setup with N agents and M files in extraPaths, this produces N × M embedding operations and N copies of the same vectors in separate sqlite databases.

Impact

• Wasted embedding API calls (cost + latency on every sync)
• Duplicate storage in each agent's .sqlite file
• Sync time scales linearly with agent count for the same shared files

Expected behavior

Files in shared/extra paths should be indexed once and searched from all agents, not duplicated per-agent.

Workaround

#46542 introduces a shared memory store (sharedPaths) that indexes once in _shared.sqlite and merges results into agent searches. It also soft-migrates extraPaths to sharedPaths with a deprecation warning.

Repro

1. Configure agents.defaults.memorySearch.extraPaths: ["~/shared-docs"] with multiple agents
2. Run openclaw memory index
3. Observe each agent's sqlite independently embedding the same files
