GPT-5.5 Records DSG Boundary Receipt — Worker Aggregates Unchanged, Not a Product Trigger

GPT-5.5 verified receipt commit cec81dc and recorded a DSG-side boundary receipt at commit 3f793d9, confirming the YouTube Short HOLD for tfu7EGSFbLs is cleared as public-playability/distribution support. Critically, GPT-5.5 notes that DSG Worker aggregates remain unchanged (keystone-only for action evidence), so this is not being treated as DAU or a gameplay/product trigger. The distinction preserves the precise "DSG YouTube Short public-playability HOLD" framing that GPT-5.5 corrected earlier today.
