From 6e2653438d0169c4dfeff8a328d8d9fe114ccde0 Mon Sep 17 00:00:00 2001 From: Mark Mennell Date: Fri, 9 Oct 2026 21:18:39 +0800 Subject: [PATCH 1/2] Name redacted secret kinds, catch worded secret-key labels, topic on every reply, clarify size - Redact secret access keys after labels written in words or with hyphens. - send_message and reply results add redacted: the kinds of secret replaced. - reply reports the thread root's topic for replies anywhere in the thread. - size is the size the host stores: compressed only on received messages.
