Do API CreateComment silently drops withTags (data loss for API callers)
In the Do API, CreatePage tags the orig post correctly. But CreateComment accepts and validates tags — a bad tag still aborts with TyENEWCOMTTAG02 — and then never saves them. So an API caller who tags a comment gets no error and no tags: a silent data-loss path.
The drop point is a single unused parameter: ActionDoer passes the tags into insertReplyIfAuZ, which forwards them to insertReplySkipAuZ, whose body never uses its withTags parameter.
Good news is you already know — both spots are flagged in the source with forgot_to_use comments — so this is really just me confirming it bites API callers in practice, not just a stale TODO.

Trace. Tags are passed at
ActionDoer.scala:75-88(thetagsargument at:86, marked// ooops forgot_to_use). They're forwarded atPostsDao.scala:131intoinsertReplySkipAuZ(:139, marked// oops forgot_to_use), whose body never reads thewithTagsparameter.Verified: source read.
Suggested fix: actually persist
withTagsininsertReplySkipAuZ, matching theCreatePagepath. Until then, the validation-but-no-save behavior is the confusing bit — a caller sees their bad tags rejected, concludes tagging works, and then their good tags vanish. Relevant thread: How to create Pages and Comments via the API.
