# Conventions match the deployed user-engine workload: digest-pinned image from

|
|
# platform-pg-consumer-ingress in the databases namespace admits, so without it

then NOT NULL. An image that does not write those columns cannot accept

events after 0006. Do not roll back past sha256:7febc28e… to a pre-0007

writer. A future migration that drops or narrows a column must state
|

its own rollback position before it is released.
