The 100-line combined log dump was entirely filled by litestream R2 errors, hiding the actual blue-app crash output. Now dumps blue-app (60 lines), router (10 lines), and litestream (10 lines) separately. Revert litestream image tag to latest — the R2 errors were caused by misconfigured endpoint/bucket CI variables, not a litestream version bug. The v0.5.8 tag may not exist on Docker Hub (tags omit 'v' prefix). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
