# 21 — Samsung S21 ## Status ```text S21_LIVE_INTEGRATION=PLANNED S21_ROOT_REQUIRED=NO ``` ## Authority `docs/product/product_definition.md`. ## REQUIRED_PRODUCT_TARGET The S21 uses a device-specific acquisition adapter only at the device/acquisition boundary. Required properties: - no root; - no scientific-core fork; - graceful disconnect/reconnect; - explicit full-resolution Capture ingestion; - preview frames remain ephemeral until promoted; - exact optical/calibration assignment for scientific use. The exact Android transport is deliberately deferred until implementation research proves the best supported mechanism. ## Canonical-reference rule When implementation enters this area, read the cited canonical document in full before editing. If this prompt summary and the canonical document appear to conflict, do not silently choose the shorter text: determine whether this file is stale or whether a real contract contradiction exists, then apply the STOP rules where necessary.
