+"""Boardroom taste: a backrooms-style turn loop over claude + codex, transcript on an issue.
+
+    python3 -m phastacp.taste --turns 6 --agenda "..."     (from the repo root, on hb-5)
+
+- participants are seats; each seat's role prompt is seats/<seat>.md in the repo
+- a turn = (role prompt + transcript so far + "your turn") -> the seat's CLI, headless
+- every turn is posted to the room issue *as the seat* (bot user), so the URL is the room
+- commands a seat may use at the start of a line:
+    !pass                 skip the turn
+    !prompt <text>        propose an amendment to your own seat prompt (recorded, never applied here)
+    @<seat>               hand the next turn to that seat (default: round robin)
+No GUI, no OpenRouter, no RAM state worth keeping: kill it and the issue is the record.
