Batch Signoff Source Gap Tool

Description

Count empty sources, literal role mismatches, and rows with nonempty source, matching role, and verified flag.

Good manufacturing practice records connect materials, actions, people, and source evidence. A local check can expose missing or inconsistent metadata, but it cannot authenticate a record or replace quality-system review.

Count empty sources, literal role mismatches, and rows with nonempty source, matching role, and verified flag.

When to use this tool

Use Batch Signoff Source Gap when you need a literal manufacturing-record or source-support diagnostic.

How to use the tool and how it works

Enter stepIds, signoffSources, requiredRoles, recordedRoles, sourceVerified. Keep parallel arrays aligned. Use the units and conventions below.
Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
Read steps, missingSources, roleMismatches, verifiedMatchingSignoffs. Use the output convention below.

Require aligned stepIds, signoffSources, roles, and sourceVerified flags with unique step IDs. Count empty sources, literal role mismatches, and rows with nonempty source, matching role, and verified flag.^[1]

Input field	Meaning and units	Accepted input
stepIds	Step Ids	Required. Array of text; maximum UTF-16 length 8192; maximum items 256.
signoffSources	Signoff Sources	Required. Array of text; maximum UTF-16 length 8192; maximum items 256.
requiredRoles	Required Roles	Required. Array of text; maximum UTF-16 length 8192; maximum items 256.
recordedRoles	Recorded Roles	Required. Array of text; maximum UTF-16 length 8192; maximum items 256.
sourceVerified	Source Verified	Required. Array of boolean; maximum items 256.

Output field	Interpretation	Returned shape
steps	Steps	Required. Safe integer.
missingSources	Missing Sources	Required. Safe integer.
roleMismatches	Role Mismatches	Required. Safe integer.
verifiedMatchingSignoffs	Verified Matching Signoffs	Required. Safe integer.

Limitations and assumptions

Counts describe supplied metadata; sourceVerified is not independently checked and no identity authentication, cryptographic signature, authorized release, or complete signoff compliance is established.
Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.

Alternative or Complementary methods

Use the controlled record system to verify identity, provenance, approvals, and complete audit history. Treat local flags as prompts for investigation rather than release or compliance decisions.
