 ### Fixes
 
+- Memory/LanceDB embeddings: forward configured `embedding.dimensions` into OpenAI embeddings requests so vector size and API output dimensions stay aligned when dimensions are explicitly configured. (#32036) Thanks @scotthuang.
 - Mentions/Slack formatting hardening: add null-safe guards for runtime text normalization paths so malformed/undefined text payloads do not crash mention stripping or mrkdwn conversion. (#31865) Thanks @stone-jin.
 - Failover/error classification: treat HTTP `529` (provider overloaded, common with Anthropic-compatible APIs) as `rate_limit` so model failover can engage instead of misclassifying the error path. (#31854) Thanks @bugkill3r.
 - Voice-call/webhook routing: require exact webhook path matches (instead of prefix matches) so lookalike paths cannot reach provider verification/dispatch logic. (#31930) Thanks @afurm.
