Summary (under 1500 chars):

- Exact error message and exit code
  - bash: line 1: warning: here-document at line 1 delimited by end-of-file (wanted `EOFnBuilding')
  - cat: from: No such file or directory
  - cat: source...nEOF: No such file or directory
  - ERROR: failed to build: failed to solve: process "/bin/sh -c bash -lc 'cat > /workspace/dist/build.log << \"EOF\"\\nBuilding from source...\\nEOF'" did not complete successfully: exit code: 1

- Failing command/step
  - Stage: builder 6/7
  - Command: RUN bash -lc 'cat > /workspace/dist/build.log << "EOF"\nBuilding from source...\nEOF'
  - Dockerfile line: 16

- Missing packages or files mentioned
  - No explicit missing packages/files reported. The errors stem from a broken here-document, not from apt/file operations. Earlier package installs succeeded.

- Version mismatch info
  - Base image: ubuntu:22.04 (Jammy)
  - The log shows standard apt installs completing for that base image (tzdata, ca-certificates, openssl, etc.) with various versioned packages (e.g., tzdata 2025b-0ubuntu0.22.04.1, openssl 3.0.2-0ubuntu1.21), but there is no explicit version mismatch error.
