      "Issue #809 tracks Oh-My-Pi 15.7.3 shake compaction primitives: collectShakeRegions, applyShakeRegion(s), summarizeShakeRegions, default/aggressive configs, and related compaction types.",

      "The shake compressor is provider-agnostic and can be wired to local on-device models, so adapter metadata should distinguish local-on-device compression backends from remote provider-managed compaction.",
      "Related 15.7.2 metadata adds providers.autoThinkingModel plus auto thinking-level classification for user turns.",
