From: Anderson A. Giacomolli Date: Wed, 11 Nov 2026 17:30:02 +0000 (-0300) Subject: Queue external data for the next root turn X-Git-Url: https://git.giacomolli.uk/onechat/commitdiff_plain/d7bc0a6ac452bfc646610fdfd7c8eccb5c55218f Queue external data for the next root turn Root events stay in the durable agent queue until a turn boundary, so accepted data cannot enter an active tool chain or its memory view. Source and event IDs bind retries to the accepted text across restart and completion. A fixed receipt cap rejects new keys without discarding pending work or retry protection. External data carries its receipt time and an explicit trust boundary. Quoted bodies cannot create image attachments, and raw events do not produce task-worker completion notices in Telegram. Delivery recovery can repeat model calls and tool effects, not delivery log entries.
