CI Failures

If CI is failing, it may be because updating the schema broke some code integrations. In that case, a human should manually fix the code to make it work before merging. This is the responsibility of the PR creator.

Closing: the generated artifacts target content/en/security/guide/findings-schema/generated/*.md, but the live page is the single file content/en/security/guide/findings-schema.md. Publishing this would add 7.4k lines at a new path that shadows the existing page's URL rather than updating it. Needs a fix in the publish tool's documentation output paths first. The batch's actual schema change (custom._dd.sds_info) is internal-only and does not surface in the customer-facing reference, so documentation has nothing to ship this batch.
