+"""Render agent markdown into Slack Block Kit blocks.
+
+Opt-in (``slack.extra.rich_blocks: true``) alternative to the flat mrkdwn
+``text`` payload produced by :meth:`SlackAdapter.format_message`.  Block Kit
+gives us real structural primitives — section headers, dividers, and true
+*nested* lists via ``rich_text`` — that plain mrkdwn can only approximate.
+
+Design constraints (why this module is deliberately conservative):
+
+* **Markdown pipe-tables render as native ``table`` blocks** — real grid
+  cells with per-column alignment and inline-formatted ``rich_text`` content.
+  A table that exceeds Slack's limits (100 rows / 20 cols / 10k aggregate
+  cell chars) or won't parse falls back to aligned monospace
+  ``rich_text_preformatted`` so a large table never breaks the message.
+* **Slack caps a message at 50 blocks** and a ``section``/text object at 3000
+  characters.  :func:`render_blocks` enforces both and, if the content simply
+  cannot be expressed within them, returns ``None`` so the caller falls back
+  to the plain-text path.  A rich render is a nice-to-have; it must never lose
+  a message.
+* **Every blocks payload MUST ship a ``text`` fallback.**  Slack uses it for
+  notifications, screen readers, and old clients.  This module only builds the
+  ``blocks`` list; the adapter pairs it with the existing mrkdwn string.
+
+The renderer never raises: any unexpected input degrades to ``None`` (caller
+uses plain text).  It is a pure function of its input — no Slack client, no
+adapter state — so it is trivially unit-testable.

-# Bootstrap Open WebUI against Hermes Agent's OpenAI-compatible API server.

-# Idempotent by design:
-# - ensures ~/.hermes/.env has API server settings
-# - installs Open WebUI into ~/.local/open-webui-venv
-# - writes a reusable launcher at ~/.local/bin/start-open-webui-hermes.sh

+"""Regression test for #20271: classic-CLI hangs when messages typed during
+an agent turn never leave ``_interrupt_queue``.
+
+Background
+----------
+The CLI routes user input typed while ``_agent_running`` is True into
+``_interrupt_queue`` (separate from ``_pending_input``) so that the explicit
+interrupt path can opt to deliver them as a single combined "interrupt"
+message. The explicit drain at the top of ``process_loop`` only fires when
+``busy_input_mode == "interrupt"`` AND a ``pending_message`` was
+acknowledged.
+
+The original PR #17939 paired the paste-file TOCTOU fix with a separate
+drain inside ``process_loop``'s ``finally`` block: any message left in
+``_interrupt_queue`` after the agent's turn ends gets re-queued onto
+``_pending_input``. The drain was split off in #17666 / #18760 as "worth
+its own review" and never re-landed. v0.12.0 users hit a hang when typing
+during a turn that completes naturally — the message sits in
+``_interrupt_queue``, the next ``Enter`` re-routes input to the same
+blocked queue, and the CLI looks frozen.
+
+This test exercises the restored ``_drain_interrupt_queue_to_pending_input``
+helper that ``process_loop`` now calls every turn. The integration into
+``process_loop`` itself is not threaded here (it requires a real
+prompt_toolkit app); the helper is unit-testable on its own and is the
+load-bearing piece.
