HOW THIS VERIFICATION WORKS

Step 1: Calculate station-level data completeness ratio — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
Step 2: Validate monotonic timestamp ordering in audit log — compares engineering inputs against deterministic thresholds and produces a PASS or FAIL decision.
Step 3: Verify cryptographic hash chain continuity — compares engineering inputs against deterministic thresholds and produces a PASS or FAIL decision.

This tool coordinates 2 validation steps and 1 calculation step. The overall engineering decision uses ALL_REQUIRED_VALIDATION_PASS aggregation: only validation steps contribute to the pass/fail outcome; calculation steps produce data only.

METHODS & EQUATIONS

All formulas are resolved from canonical runtime definitions and executed deterministically by the client-side engine.

Step 1: Calculate station-level data completeness ratio

FormulaP_act/P_exp

Step 2: Validate monotonic timestamp ordering in audit log

Manual Workflow

For i = 1 to len(τ)−1: assert τ[i] ≥ τ[i−1]; T_mono = True if all assertions hold, else False.

Step 3: Verify cryptographic hash chain continuity

Manual Workflow

For each entry i > 0: compute SHA-256(H_prev[i] + τ[i] + payload[i]); compare result to H[i]. H_valid = True iff all matches succeed.

UNDERSTANDING THE RESULTS

PASS: A proven validation criterion passed. The engineering input satisfies the deterministic threshold.
FAIL: A proven validation criterion failed. The engineering input does not satisfy the deterministic threshold.
CALCULATED: A deterministic calculation completed, but no acceptance criterion exists for this step. CALCULATED does NOT mean PASS.
RESULT NOT VALID: Runtime executed but engineering validity requirements were not met.
INCOMPLETE: Required inputs or workflow steps are incomplete.

The overall decision reflects only validation steps. Calculation steps produce numerical results without pass/fail claims.

WHEN TO USE THIS TOOL

When deterministic Battery Module Assembly Line engineering verification is needed for project-specific conditions.
For calculation of Calculate station-level data completeness ratio (Step 1).
For validation of Validate monotonic timestamp ordering in audit log (Step 2).
For validation of Verify cryptographic hash chain continuity (Step 3).
For deterministic pre-checks before formal engineering review or submission.

When NOT to use this tool: This tool does not replace laboratory testing, formal engineering analysis by a licensed professional, or code-compliance certification. It performs deterministic threshold comparison and calculation only.

ENGINEERING FAQ

What does this verification tool check?

This tool performs 3 deterministic engineering steps: (1) Calculate station-level data completeness ratio, (2) Validate monotonic timestamp ordering in audit log, (3) Verify cryptographic hash chain continuity.

What does a PASS result mean?

A PASS result means the validation step's deterministic threshold comparison was satisfied. It does not constitute laboratory certification or code compliance.

What does a CALCULATED result mean?

A CALCULATED result means the deterministic calculation completed, but no acceptance criterion is applied to this step. CALCULATED does NOT mean PASS.
