Resolve awkward line endings

Prepare a representative pass

Distinguish an isolated boundary line from a visually weak last line, then assess the whole reflow. Use a saved working copy, identify the intended active document, and check the inspection scope before interpreting a result. A profile is an inspection brief, not a command to repair the document.

Follow the workflow

Inspect a representative chapter with the intended scope and whole-story policy. Read the exact Copyfit finding and coverage.
Locate the affected paragraph and page/frame boundary. Determine whether the concern is a widow/orphan, a short last line or another fit constraint.
Check paragraph-style Keep Options and the design intention in InDesign. A short caption or title can legitimately have a different shape.
If the selected compatible finding offers Preview fix or Explore fixes, read its goal, target and Before/After evidence.
Compare the strategy and side effects. A small improvement at the target is insufficient if it creates overset or an unacceptable break elsewhere.
Apply an eligible result or make a deliberate manual adjustment. Inspect again and review the surrounding spread and threaded story.

How to recognize a finished pass

The actual boundary concern is identified.
The target improves without unacceptable downstream reflow.
Final evidence uses the same intended scope and policy.

Where judgement matters

Minimum paragraph length for short-ending review is not a widow definition.
A goal name does not promise that a safe candidate exists.

Does a finding mean I must change the document?

No. Check intent, scope, current evidence and available actions. Retaining an intentional occurrence can be the correct decision. Record the supported review status when useful; it does not edit the source text.
