From b48809485cebb2820c7d5a6a3f1e1a27bf1caf72 Mon Sep 17 00:00:00 2001 From: nickyleach <331803+nickyleach@users.noreply.github.com> Date: Thu, 10 Sep 2026 08:29:43 +0000 Subject: [PATCH] feat(server): cap the item counts in the wake payload The wake payload builder copied every comment, interaction outcome, and completed action into the envelope with no limit. Add an item cap of 30 to six lists as a guard against a pathological item count. The cap keeps every origin message, keeps each message object complete, and does not change the objective. It reports the number of dropped messages on coverage.omittedMessageCount, and the prompt no longer claims a complete history when the cap drops a message.
