## Which issue does this PR close? N/A. Documentation cleanup. ## Rationale for this change The Spark expression support reference (`expressions.md`) defines four statuses in its legend, but two of them, "⚠️ Incorrect by default" and "💤 Not currently planned", are not used by any row in the expression tables. Listing statuses that never appear is confusing and invites readers to look for rows that do not exist. The file-metadata functions (`input_file_name`, `input_file_block_start`, `input_file_block_length`) are technically Catalyst expressions, but their unsupported status is a scan-layer property and is already documented in the scan compatibility guide. Keeping a second copy in the expression reference risks the two pages drifting apart. ## What changes are included in this PR? - Remove the unused "Incorrect by default" and "Not currently planned" rows from the status legend. - Drop the intro sentence and "See also" wording that referenced the removed "Incorrect by default" status. - Replace the "File metadata" bullet in the not-planned list with a short cross-reference to the scan compatibility guide, which is the canonical place for that limitation. ## How are these changes tested? Documentation-only change; verified by rendering the page and confirming no remaining references to the removed statuses. -- This is an automated message from the Apache Git Service.
