Summary

Fixed YAML syntax error in release workflow that caused startup_failure on v0.24.19 release.

Problem

Release workflow failed with startup_failure error when processing tag v0.24.19:

• Run: https://github.com/RAprogramm/masterror/actions/runs/18441530077
• Error: Workflow file issue

Root Cause

Heredoc delimiters in release.yml used custom names with potential YAML conflicts:

cat > "${TMPDIR}/src/main.rs" << 'RUST_EOF'
...
RUST_EOF

cat > "${TMPDIR}/Cargo.toml" << 'TOML_EOF'
...
TOML_EOF

GitHub Actions YAML parser had issues with these delimiter names.

Solution

Simplified heredoc delimiters to standard EOF:

cat > "${TMPDIR}/src/main.rs" << 'EOF'
...
EOF

cat > "${TMPDIR}/Cargo.toml" << 'EOF'
...
EOF

Note: Single quotes around 'EOF' are maintained to prevent variable expansion in heredoc content.

Changes

• Line 125: 'RUST_EOF' → 'EOF'
• Line 159: RUST_EOF → EOF
• Line 161: 'TOML_EOF' → 'EOF'
• Line 169: TOML_EOF → EOF

Test Plan

• YAML syntax validated
• Heredoc functionality preserved
• Variable expansion still prevented by single quotes

Next Steps

After merge:

• Re-run release workflow for v0.24.19
• Verify crates.io publish succeeds
