Abstract
Owners of underwater systems for telecommunications, oil and gas production, exploration, or military use typically require a proven history of performance and/or extensive development and qualification prior to deployment. As a result, suppliers of such systems normally take a cautious and deliberate approach to the introduction of new technologies. Development involving the construction of a prototype and deployment at sea may last years. Even incremental improvements may require extensive qualification tests stretching over eighteen months or more. Entirely novel approaches may be shelved due to the cost of trials or test deployments. Science communities around the world are installing, or proposing to install, a new generation of cabled infrastructure that will provide standard communications and power interfaces in the deep ocean. The first of these large scale observatories, NEPTUNE Canada, is scheduled for final deployment in 2008. While the primary goal of cabled ocean observatories is observation of the ocean environment, engineering research is also encouraged, and facilities can be made available for use demonstration and qualification of new technologies. The primary interfaces to NEPTUNE Canada are the node science ports. Each science port provides optical Gigabit Ethernet connection and up to 9 kW of power at 400 volts DC. These interfaces are suitable for connection of equipment within a few kilometres of the node. For longer extensions, a power interface providing a direct connection to backbone power at 5 to 10 kV, and long reach optics are available. The NEPTUNE Canada physical infrastructure consists of an 800 km loop beginning and ending at Port Alberni British Columbia. NEPTUNE nodes are located at depths ranging from 100 m to 2700 m, which encompasses the range at which most commercial subsea activity takes place. There are active hot volcanic vents, outcrops of gas hydrates and existing ODP drill holes adjacent to the planned node sites. These capabilities make the new generation of ocean observatories, and NEPTUNE Canada in particular, an ideal test bed for any application requiring high bandwidth communication and hundreds or thousands of watts of electrical power. Communication between the nodes and shore is provided via Ethernet and wavelength division multiplexed optics. A 10 Gb/s backhaul link from Port Alberni to Victoria provides a connection to the Internet. VLANs and VPNs can be established to provide direct access to connected equipment.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
