.SYNOPSIS
|
||||
Verifies the Module 03 challenge solution (checkpoint-aware).
|
||||
|
||||
.DESCRIPTION
|
||||
This script can verify completion of individual checkpoints or
|
||||
the entire module. Without arguments, it verifies all checkpoints.
|
||||
|
||||
.PARAMETER Checkpoint
|
||||
The checkpoint to verify: start, merge, or merge-conflict.
|
||||
If not specified, verifies all checkpoints.
|
||||
|
||||
.EXAMPLE
|
||||
.\verify.ps1
|
||||
Verifies all three checkpoints are complete.
|
||||
|
||||
.EXAMPLE
|
||||
.\verify.ps1 start
|
||||
Verifies only the branching basics checkpoint.
|
||||
|
||||
.EXAMPLE
|
||||
.\verify.ps1 merge
|
||||
Verifies only the merging checkpoint.
