about

nx_fetch_unit.nx -- the SHARED staged-fetch unit (Rule #15: this logic lived copy-pasted in _dlr_fetch_one + _ed_fetch_html; extracted 2026-06-10 in the standards audit so the next consumer inherits fixes instead of forking them). module: nishi-core.search.fetch_unit depends: nx_https_get.nx stack capability: CORE_COMPUTE nx_fetch_staged(url, bodybuf, cap): validated-HTTPS GET with 301/302/303/307/308 Location follow (https-only, hop-capped FU_HOPS) and Transfer-Encoding chunked DECODE. Returns decoded body length into bodybuf, or 0/negative on failure. Callers decide what the body becomes (html->text, raw html, header probe...).
