5 dead file references in v4.0.1 (files referenced but never shipped)

[jdrolls]

Summary

After upgrading to v4.0.1, I ran a comprehensive dead-reference audit across all PAI files. Found 5 references to files that don't exist in the repo — they're referenced in code/docs but were never shipped.

Dead References

Referenced Path	Referenced From	Type
PAI/DEPLOYMENT.md	PAI/CONTEXT_ROUTING.md, PAI/DOCUMENTATIONINDEX.md	Doc
PAI/BROWSERAUTOMATION.md	PAI/CONTEXT_ROUTING.md, PAI/DOCUMENTATIONINDEX.md	Doc
skills/PAI/Tools/FileBasedMCPs.md	skills/PAI/Tools/SKILL.md line 23	Tool doc
skills/Aesthetic/SKILL.md	skills/PAI/USER/SKILLCUSTOMIZATIONS/README.md	Skill ref
skills/BackgroundRemoval/SKILL.md	skills/PAI/USER/SKILLCUSTOMIZATIONS/README.md	Skill ref

How I Found This

Ran rg across all .md and .ts files for path references, then verified each target with ls. These 5 are files that are referenced in upstream code but don't exist in the repo at any path.

Additional Context

This is separate from PR #836 (which addresses dead refs in CONTEXT_ROUTING.md). These 5 span multiple files and include references in TypeScript tool files, not just docs.

Environment

• PAI version: v4.0.1
• Platform: macOS (Darwin 25.3.0)

Additional finding: loadAtStartup references non-existent file

settings.json in v4.0.1 has this in loadAtStartup.files:

"PAI/USER/PROJECTS/PROJECTS.md"

But the actual file in PAI/USER/PROJECTS/ is README.md, not PROJECTS.md. This means LoadContext.hook.ts silently fails to load the projects context every session.

Fix: Change to "PAI/USER/PROJECTS/README.md" in settings.json, or create the PROJECTS.md file.

This is in addition to the 5 dead refs in the original issue.
