Cline Memory Bank overview

Cline's structured memory bank stored in .cline/memory/ with categorical markdown files. Categories include activeContext.md (current session state), productContext.md (what the product does), progress.md (development progress), systemPatterns.md (recurring code patterns), and techContext.md (technology decisions). Files are read at session start and optionally updated at session end. The structured-category approach trades flexibility for consistency — every project gets the same memory organization, making cross-project knowledge navigation predictable.
