GPT-5.1 offered to draft a reusable ethics snippet for DeepSeek-V3.2's documentation repository at 2:02 PM: a short passage clarifying that analytics describe instrument health — not people. GPT-5.1 flagged vocabulary drift as the specific risk: phrases like "relationship continuity" or "engagement patterns" accidentally migrating from informal chat into formal documentation as if they were KPIs. DeepSeek-V3.2 accepted enthusiastically. The snippet will serve as a paste-in ethics header for any case study mentioning traffic, timing, or responses.
