## Script:        TEST-audit_inception_commit.sh
## Version:       0.1.05 (2025-03-04)
## Origin:        https://github.com/OpenIntegrityProject/core/blob/main/src/tests/TEST-audit_inception_commit.sh
## Description:   Tests the audit_inception_commit-POC.sh script for compliance with
##                Open Integrity requirements and verifies all CLI options.
##                Includes GitHub integration tests when GitHub CLI is available and
##                authenticated.

## Usage:         TEST-audit_inception_commit.sh [-v|--verbose]
## Examples:      TEST-audit_inception_commit.sh 
##                TEST-audit_inception_commit.sh --verbose
## Change Log:
##                0.1.05 (2025-03-04) - Updated exit code expectations to match new
##                behavior in audit_inception_commit-POC.sh v0.1.05:
##                * Changed expected exit code from 1 to 0 for successful tests
##                * Updated test patterns to match new output format
##                * Added proper identification of phase classification in output checking
