Walkthrough

Adds Git LFS tracking entries for two PNG assets and inserts duplicated Figure 1 blocks into the Presto UI user guide describing UI components and usage notes.

Changes

Cohort / File(s)	Summary
Git LFS Configuration ​.gitattributes	Registers clp-presto-ui.png (root) and docs/src/user-docs/clp-presto-ui.png for Git LFS with filter=lfs, diff=lfs, merge=lfs, and -text.
Documentation Update docs/src/user-docs/guides-using-presto.md	Inserts two identical Figure 1 blocks (duplicated) showing clp-presto-ui.png and a numbered list describing Presto UI elements (filter inputs, time range selector, Freeform selector, results timeline, results table, query inspector) plus usage notes (single query at a time, no trailing semicolon).

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Pay attention to the duplicated Figure 1 insertion in docs/src/user-docs/guides-using-presto.md (intentional duplication vs. accidental).
• Verify image paths in .gitattributes match repository layout and that the LFS rules apply as intended.

Learning: In the CLP webui Presto configuration, host and port are set via package settings (configurable), while user, catalog, and schema are set via environment variables (environment-specific). This mixed approach is intentional - settings are typically set by package and some values don't need to be package-configurable.

🔇 Additional comments (2)

docs/src/user-docs/guides-using-presto.md (2)

206-206: Specify the image directory path.

Line 206 references clp-presto-ui.png without a directory prefix. Verify the image location and update the path accordingly (e.g., ./clp-presto-ui.png if in the same directory, or a relative path to the assets folder).

---

201-240: No duplication found. The review comment's concern is unfounded.

The verification confirms:

• The (figure-1)= reference definition appears only once (line 203)
• Two links to Figure 1 exist at lines 201 and 212, both pointing to the same single definition
• The image file clp-presto-ui.png exists at the correct location

Having multiple references to a single figure definition is standard practice in documentation and is correct. The AI-generated summary mentioned in the original review comment mischaracterized the code structure.

Likely an incorrect or invalid review comment.
