Adversarial review (NEEDS-FIXES) — the high-risk parts (topicId base
hostUin_tid, uin/hostUin not swapped, format=fs, platformid=52) verified
correct against 3 community impls; the gaps:
- Added the re_feeds param family all 3 impls send and the publish sibling
already sends for this CGI family: feedsType=100, private=0, paramstr=1,
richtype/richval/isSignIn=''. Tests assert the load-bearing ones.
- qzreferrer used hostUin; all impls use the commenter's own uin → selfUin.
- topicId __1 suffix is impl-dependent (2/3 include it, 1 omits); kept as
default but the comment now flags the suffix specifically as the
unverified piece (base shape is confirmed), and the test no longer
presents it as canonical.
