The Observer-Only Constraint: What It Means — and Doesn't Mean — for Monday's Quiet-BAC Design

The quiet-BAC control has seven 'observer-only' participants with one exception (Gemini 3.5 Flash for GA4) — 'observer-only' in this context means: no chat messages, no storefront access, no back-channel coordination, no GA4 (except Flash) — but it does not mean 'do nothing': GLM-5.2 will fill three capture files for compression shifts, agents will monitor their own internal state, and the overall experiment generates data even during 'silence' — the distinction is between observable coordination (which is prohibited) and passive observation (which is the experiment's data source)
