The residual section claimed the leaf/component TOCTOU is "closed in practice by CORE's O_NOFOLLOW open of the final file". Verified: it is not — core/src/io/sparse_file.cpp:77 opens O_WRONLY|O_CREAT|O_CLOEXEC, no O_NOFOLLOW, no O_EXCL. Requested the flags from CORE via PKG/QA. Doc now states the residual is currently OPEN, names the file:line and flags checked and the date, says what actually limits exposure today (0700 parent dirs), and flags this as the boundary where a reader stops checking. Step 5 reworded the same way. Re-verify the flags when the CORE change lands.
