[ci-maintainer] Import reference architectures fails at validate:architectures — SVG→PNG conversion does not rewrite asset reference (run 35175044427) #218

CI Issue

The daily Import reference architectures workflow now fails one step later than before. The librsvg2-bin fix landed (the apt install step runs and import:architectures succeeds), but npm run validate:architectures fails:

[error] swisscom-cloud-native-telco: missing asset /img/architectures/swisscom-cloud-native-telco/swisscom-cloud-native-telco-automation-architecture-overview.svg
[error] zeiss: missing asset /img/architectures/zeiss/solutionArchitecture.svg

Root cause: scripts/import-architectures.mjs converts raster-embedded SVGs to PNG:

Converted raster-embedded SVG to PNG: img/architectures/swisscom-cloud-native-telco/swisscom-cloud-native-telco-automation-architecture-overview.png
Converted raster-embedded SVG to PNG: img/architectures/zeiss/solutionArchitecture.png

but does not rewrite the asset reference in the architecture MDX/frontmatter, which still points at the .svg path. Validation then looks for an .svg that the import deliberately never wrote.

Evidence

• Failing run: 35175044427 (2026-09-17T02:36, schedule), step Run npm run validate:architectures, exit 1.
• Prior failure mode (raster-embedded SVG rejection, missing rsvg-convert) is resolved — this supersedes the remaining part of [ci-maintainer] Import reference architectures fails daily: raster-embedded SVGs, rsvg-convert missing (fix PR #49 open) #121.

Recommendation

In scripts/import-architectures.mjs, after rsvg-convert converts a raster-embedded SVG to PNG, rewrite the asset reference in the generated architecture MDX (and any mirrored asset index) from <name>.svg to <name>.png so validate:architectures checks the file that actually exists.

Coordination note: scripts/import-architectures.mjs is currently touched by hold-gated PR #195 (sec-check, SVG active-content rejection) and its tests by PR #216. This fix should land after/rebased on those to avoid conflicts.

Completion criterion

• Import reference architectures scheduled run passes validate:architectures with the two raster-embedded architectures present as PNG assets referenced from their MDX.
