      "Excerpt": "## Problem\n\nThe `validateSelector()` function in `src/upload-validator.ts:220` uses `\\s` in its character allowlist, which matches raw newlines (`\\n`) and carriage returns (`\\r`) in addition to spaces and tabs. Raw newlines in a CSS selector are not valid CSS and could produce unexpected behavior in error messages that echo the selector (e.g., `src/cdp-client.ts:1625`: `No element found matching selector: ${selector}`).\n\n**Source**: PR #32 — fix(security): validate selector parameter before DOM.",
