Anchor-precision audit: fixed okiacag→okgsid2 anchor drift, bambustudio C++ macro whitespace + User-Agent format, bambu-blog glyph mismatch, sfc-copyleft training-data contamination on Welte-line cases (kept D-Link/Fantec with primary gpl-violations.org sources, deleted Sitecom/Skype). Pipeline hardened with anchor-precision rule + build-log contract; see fixes-postaudit.md and rescorecard-v2.md.

Fix anchor-drift citation: the 'gym on a public square' blockquote was reusing a different Pawel Jarczak comment's ref (okiacag, plugin-severability syllogism). Repointed to the correct comment URL (okgsid2). Other improvements pending broader audit.
