The four full my.cnf profiles under etc/lp, etc/dev, etc/corp, and
etc/portal are the source templates for sites. They share the safe fleet
policy established during the 2026-08 MariaDB tuning: query cache disabled,
realistic table/file caches, thread_stack=512K, and bounded temporary and
per-operation buffers.
The profile determines only the fixed working-set and connection tier:
lp/dev: 32 MiB InnoDB pool, 10 connections;corp: 64 MiB pool, 25 connections;portal: 128 MiB pool, 50 connections.
A site with a database that needs a larger working set must receive a separately reviewed configuration and explicit Docker memory/no-swap limits; do not raise the shared template values for one project.
