Use file briefs after processing

A file brief is a short review aid for a processed file.Use it to orient yourself before deeper source review. Brief availability depends on file processing.Briefs are created after Reia prepares the file's pages, tables, and context for review. They appear when Reia can create a useful summary from the processed material, so they are usually stronger after the source file has processed cleanly.## Brief statesBrief not ready means the file has not been processed. Brief in progress means processing is still running. Processing failed means processing did not finish. Brief unavailable means the file was processed, but no brief is available.## If a brief is missingIf a brief is not ready, process the file first. If processing is still running, check again later.If processing failed, retry processing. If a brief remains unavailable after a successful process, open the file directly and keep working from the processed source context.Briefs are a fast entry point into large files. Use them to find the right section, then follow source references and the original file when a detail matters.
