From 812e3ee265192dc2ad41c9d9cc9f9833bc0d61ad Mon Sep 17 00:00:00 2001 From: WHC Date: Thu, 29 Oct 2026 11:29:38 +0800 Subject: [PATCH] feat: parliament seat collaboration loop (0.9.19) Seats publish via parliament_note, sync pushes on write, member join without stealing the chair, and worker tools are hard-gated when parliament is active.
