From 8de27afa2c95776ebe53ca106c8450a2c3165d6b Mon Sep 17 00:00:00 2001 From: Dhravya Shah Date: Tue, 18 Aug 2026 08:14:00 -0700 Subject: [PATCH 1/3] feat(python-sdks): SDK-level cross-source memory deduplication Port the normalized, priority-ordered (static > dynamic > search) profile deduplication into the Python SDKs, injecting one owned memory block per request that replaces the prior block rather than accumulating. Dedup is request-local (no shared state), so it stays correct under concurrency. Covers OpenAI, Agent Framework (middleware + context provider), Cartesia, and Pipecat.
