From 86725267b65673c5564fcd6c60a5e9255427ac2a Mon Sep 17 00:00:00 2001 From: Alex Date: Wed, 1 Apr 2026 00:57:22 -0400 Subject: [PATCH 1/2] fix(checkpoint): replace custom KVStore with solnlib KVStoreCheckpointer The custom KVStore checkpoint code fails in Splunk Cloud environments because the collection may not initialize and nested object serialization doesn't round-trip correctly. Replaces with solnlib's KVStoreCheckpointer which handles initialization, error recovery, and Cloud compatibility. Flattens checkpoint data structure to avoid nested object issues. Removes key_id from EventLogsCheckpoint model (now managed by library). Includes migration from legacy 'eventsapi' KVStore collection. Adds checkpoint serialization roundtrip tests.
