The duplicate window lives in memory, and queue overflow drops events. These are deliberate limits of a small automation daemon. Current adapters are ntfy and OS-task execution.",

      "context": "Moving a photo library involves more than copying files. A Live Photo has multiple components, edited images have additional versions, and missing capture dates can scramble the destination timeline. I built the migration around explicit resource state so interruptions and partial uploads can be handled deliberately.",

          "text": "An upload attempt is insufficient evidence to delete a source. The pipeline requires a returned media key or a confirmed remote duplicate for each resource, checks a configurable age grace period, and rechecks the ledger immediately before deletion. Both components of a Live Photo must satisfy that requirement."
