Field Plausibility

This semantic rule warns on suspicious but technically decodable MISB ST 0601 values that often indicate placeholder, clipped, or operationally doubtful metadata.

What This Test Does​

The rule looks for patterns such as:

  • zero-value coordinates that resemble defaults or placeholders
  • offset corner values at clipping boundaries
  • empty operational strings that are usually populated in real telemetry

✅ Pass Criteria​

The test passes when no suspicious MISB ST 0601 plausibility patterns are detected in the decoded packets.

⚠️ Warning Criteria​

This rule is advisory. It reports warnings rather than hard failures when a value is decodable but looks operationally suspect.

Notes​

Use this rule to separate likely telemetry quality issues from strict schema failures. A warning here does not necessarily mean the packet is malformed, only that the content deserves closer inspection.
