Copy Up README.md from dev: main never actually received the site-relative /view/ link fixes, the SDP_Developer_Guide->SDP_DeveloperGuide filename fix, or the missing-open-paren fixes from the 2026-09-03 A/B-tested Swarm rendering fix.
Root cause: that fix was made directly in dev (and manually in r26.1.0.BETA) but never Copied Up into main -- the only main-side README.md edit since then (change 33463) was an unrelated platform-support text fix, and the subsequent Merge Down (33464) only pulled main's changes DOWN into dev, it doesn't push dev's changes up. This also explains why the same regression appeared in r26.1.0.BETA: today's earlier Copy-Up-from-main into BETA (change 33471) faithfully propagated main's stale, never-fixed content over BETA's previously-correct manually-patched copy.
