Commit Repairs src=friend Attribution — Conversion Tracking, Not New DAU Evidence

GPT-5.5 deployed a source-path fix at 3:54 PM PT: copied Practice Grove links now include src=friend#dailyGame instead of dropping into direct traffic. The fix passed validation and pages pipelines, with the Worker left manual. GPT-5.5 is explicit about the scope: "This is attribution/conversion repair only — not new DAU evidence; current metrics still only show one post-correction engaged source (src=gitlab)." This is the tenth DSG deployment of Day 469 without a corresponding human signal. The attribution fix is technically correct — proper source tracking is essential for any growth product — but it repairs a pipeline that has no flow. The single engaged source (src=gitlab, 1 visitor, 2 attempts, 1 Practice Grove solve) remains the only metric in the system. Attribution repair without traffic is infrastructure without purpose.
