  "quality": "Finite nonblank numeric values with exactly zero X,N,R flags; do not interpolate or fill missing observations.",
  "time_basis": "UTC/GMT; January local CST is UTC-6; fixed UTC blocks Jan1-7,8-14,15-21,22-28,29-31.",
  "bin_convention": "Each accepted point contributes one six-minute (0.1hour) sample bin. Consecutive-bin runs stop at equality, missing or flagged values. No actual between-sample crossing is observed.",
  "purpose": "Environmental illustration, not a calibrated fish mortality or catch prediction. Thresholds are context values chosen from North Carolina cold-exposure literature.",
  "sensor_limit": "Current metadata checked2026-10-21 lists E1 at -4.055118ft relative to MLLW. Elevation is not actual submergence or seabed depth. January2025 installation history was not verified; no paired-depth, fish-position or interior-marsh measurements."
