docs(memory): how to detect unused assets (srcset/URL-encoding traps)#18
Merged
Conversation
…traps Captures the reusable method for checking whether an image/PDF/CSS class is really unused (grep the built _site including .webmanifest, not just source) and the two false-positive traps hit this session: srcset responsive variants (the 2 MB hero original never ships — only its -p-* variants) and URL-encoded filenames (PDFs with %20). Also records the maintainer's decision not to delete orphaned images. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Adds a
memory/note from the improve-system review of the CSP/cleanup session.memory/finding-unused-assets.mdcaptures the reusable method for checking whether an image/PDF/CSS class is genuinely unused — grep the built_site(HTML + CSS +site.webmanifest), not just source — and the two false-positive traps hit this session:srcsetvariants: the index hero uses onlyInOEG_IRIS-One-Pager_Hero-p-*; the 2 MB full-size original is never referenced and never ships (so the earlier "optimise the 2 MB hero" idea was moot).%20, so a plaingrep -Fmisses them — all 13documents/PDFs are in fact used.Also records the maintainer's decision not to delete orphaned images.
