zit landing comment grew --reply-to, so a parented remark no longer has to detour through forum reply. Both cases go through LandingSay, which means the landing-specific error handling below — conflict and refusal decoding — now covers every remark rather than half of them.

The same-thread check stays. zit refuses an out-of-thread target too, but here it is a capability boundary: quarry does not delegate its permission model to an upstream refusal.

Artifact cards verified unchanged: G=root, I=parent, identical to what the forum-reply path produced. check-in: 3886890ee7 user: dmestas tags: trunk
