mcp-data-platform-v1.55.1

Sensible defaults for S3 bucket configuration

Three S3 config fields previously defaulted to empty strings, requiring explicit operator configuration even when convention-based names work fine. Upgrading to a version that enables portal or managed resources without also adding bucket names to config would fail at S3 call time. These fields now have defaults applied at config load time:

Config key	Old default	New default
portal.s3_bucket	""	"portal-assets"
portal.s3_prefix	""	"artifacts/"
resources.managed.s3_bucket	""	"managed-resources"

Explicit values in your config are always preserved — defaults only apply when the field is omitted.

Patch coverage script fix

The local make verify patch coverage check (scripts/patch-coverage.sh) now diffs against the working tree instead of only committed changes. Previously, the script used git diff MERGE_BASE...HEAD which skipped entirely when run before committing (the normal make verify workflow), allowing uncovered lines to slip through to CI. Now uses git diff MERGE_BASE to include uncommitted and staged changes, matching what Codecov will see after push.

Upgrade notes

• No config changes required. Existing configs with explicit s3_bucket or s3_prefix values are unaffected.
• Deployments that previously relied on empty bucket names (database-only artifact storage without S3) are unaffected — the default only applies when an s3_connection is configured.
