Response Notes

Returns the symbol signature and locations. With includeLocations=true, replacementSpans identifies supported member declarations for replace_member. Lines and UTF-16 columns are one-based, with exclusive ends. start/length are zero-based UTF-16 offsets. Read the indicated file window and exclude outer trivia from expectedText. Results use top-level fields with success. Compact is the default; full adds responseDiagnostics. Both modes retain errors, coverage, partial state, and recovery advice.
