At-a-glance capability matrix

Need	Avellio	InDesign Preflight	GREP Find/Change	Human proofreading
Missing links and low-resolution images	Outside primary scope	Strong when configured	Not appropriate	Possible but inefficient
Missing fonts and overset output risk	Limited context/guards, not certification	Strong when configured	Limited	Possible but easy to miss
Style distribution and local overrides	Strong, visual and report-led	Profile-dependent and narrower	Can target known formatting patterns	Strong judgment, slow at scale
Widows, orphans, short last lines, rag and rivers	Strong heuristic evidence	Not a general typography proofreader	Limited; composition geometry is difficult	Strong with enough time and skill
Double spaces and punctuation spacing	Strong detection; guarded fixes for supported cases	Not primary purpose	Strong for exact patterns and replacements	Strong but repetitive
Locale-aware quotes, numbers, currency, units, dates	Strong diagnostics across supported profiles	Not primary purpose	Strong only when rules are explicitly authored	Strong with locale expertise
Meaning, tone, factual accuracy, names	Not designed for this	Not designed for this	Not designed for this	Essential
Repeatable exact text transformation	Supported only for guarded Action Layer cases	Not designed for this	Excellent	Slow and inconsistent at volume
Visual heatmap and diagnostic rendering	Strong	Panel/list-based	Match navigation, not a document QA heatmap	Natural visual review
Audit evidence and issue classification	Strong Typography, Override, and Fix Reports	Preflight results and profiles	Saved query, not a QA evidence model	Depends on review process
Final production acceptance	Advisory only	Advisory output checks	Never	Accountable human decision
