Dimension Assessment
Instrument pickup detection (RFID + CV) Feasible with caveats — reliable in principle; on-metal tag compatibility must be bench-tested per instrument type
Hand-wash event detection (soap sensor) Straightforward — binary sensor, near-100% reliable, no inference required
Person attribution (~5 technicians) Feasible with caveats — wristband RFID is the reliable path; camera-only tracking degrades under occlusion
Real-time in-lab alarm Straightforward — state machine trigger to local alert hardware; latency is sub-second
Supervisor push notification + clip Feasible with caveats — clip retrieval latency must be measured; depends on network topology and storage setup
Regulatory compliance (audit trail) Unknown — depends on confirmation — ISO 15189 / GLP obligation is unconfirmed; if it applies, storage design must change
Optional features (history, reports) Straightforward — downstream consumers of the violation log; no new sensors or inference required

The system is buildable. The sensor architecture is sound and the protocol logic is deterministic. The two genuine risks are on-metal RFID reliability (solvable with bench testing before deployment) and the unconfirmed regulatory obligation (solvable with a single confirmation from the lab's quality manager). The longest pole is not engineering — it is the instrument tagging effort: physically attaching on-metal RFID tags to every instrument in the lab, verifying read reliability, and maintaining the tag registry as instruments are added or replaced.
