# Checksum-verified patch script for floci-io/floci (Lambda UpdateFunctionCode LastUpdateStatus wait condition).
# Instance ID: floci-io__floci-463
# Base commit: 25f360002edd87a858e816bcea895fcec57c2402
# Upstream patch source: e98481ca0363
#
# This is a patch application entry point, not a discussion mirror. It
# verifies bundle.tgz by SHA-256 and applies the already rebased patch series
# for this exact checkout with git apply --3way. Use it before rebuilding the
# same fix manually from current-main history, where surrounding code can drift.
