Description Punctuation Check


Punctuation-only edit — NO PUBLISH
Edit ONLY current existing project jharwinbarrozo/rn1401clf~jkz. Read actual saved project description/Description. Preserve exact text; if already ends '.', leave unchanged; otherwise trim trailing whitespace and append exactly one period. Description mutation only. No publish calls, new parts, sharing, design, URLs, MPNs, other metadata, or docs. Verify saved description via get_project readback. Return canonical URL, exact before and after, changed/already correct/failed, readback verified, zero publish calls. Fully specified single edit; skip lengthy skills/docs.
Status: already correct; unchanged. Readback verified. Zero publish calls.
Exact before and after (identical):
