AI Modification Log: x86_64 Config Comments

Date: 2026-06-29

Summary

• Added purpose and maintenance comment headers to Configs/x86_64-X, Configs/x86_64-Y, and Configs/x86_64-Z.
• Added NOTES_X86_CONFIG_OPTIMIZATION.md with config-specific optimization todos.
• Updated the handoff and backlog notes to mark item #35 as completed.

Behavior Impact

• No CONFIG_* selections were added, removed, or changed.
• The config comment update is documentation-only.

Verification

• Inspected the config diff and confirmed the three config files only gained comment headers.
• Compared CONFIG_* lines against HEAD and confirmed no config selections changed.
• Checked line endings and confirmed X stayed LF, Y stayed LF without EOF newline, and Z stayed CRLF without EOF newline.
• Ran CRLF-aware whitespace validation before commit.
