File	Summary
packages/pyright/packages/pyright-internal/src/analyzer/analysis.ts	Exports types and analyzeProgram to run a Program analysis, gather diagnostics, and invoke a completion callback
packages/pyright/packages/pyright-internal/src/analyzer/analyzerFileInfo.ts	Provides interfaces and utilities for storing per-source-file analysis metadata and import lookup in the analyzer
packages/pyright/packages/pyright-internal/src/analyzer/backgroundAnalysisProgram.ts	Manages a Program with optional background analysis, syncing config, imports, file state and diagnostics
packages/pyright/packages/pyright-internal/src/analyzer/cacheManager.ts	Tracks cache owners and heap usage to trigger cache eviction when memory usage approaches the heap limit
packages/pyright/packages/pyright-internal/src/analyzer/cellChainIndex.ts	Provides a lazily-built index mapping notebook CellDocs cells to their chain tails for fast later-cell lookups
packages/pyright/packages/pyright-internal/src/analyzer/circularDependency.ts	Represents circular import chains as ordered lists of file URIs, normalizing start and comparing equality
packages/pyright/packages/pyright-internal/src/analyzer/parentDirectoryCache.ts	Cache for storing parent-directory import lookup results to avoid repeated folder searches
packages/pyright/packages/pyright-internal/src/analyzer/program.ts	Tracks and manages the project's source files, imports, and analysis state for Pyright's type checker
packages/pyright/packages/pyright-internal/src/analyzer/programTypes.ts	Defines ISourceFileFactory interface and a type guard for creating SourceFile instances
packages/pyright/packages/pyright-internal/src/analyzer/service.ts	Analyzes Python files and manages background analysis, programs, configuration, and import resolution
packages/pyright/packages/pyright-internal/src/analyzer/serviceUtils.ts	Helpers to locate pyproject.toml and project config files starting from a given Uri
packages/pyright/packages/pyright-internal/src/analyzer/sourceFile.ts	Represents a single Python source or stub file and manages its parsing, analysis, and diagnostics
packages/pyright/packages/pyright-internal/src/analyzer/sourceFileInfo.ts	Holds per-file metadata and mutable program relations like imports, diagnostics, and edit-mode snapshots
packages/pyright/packages/pyright-internal/src/analyzer/sourceFileInfoUtils.ts	Utilities for SourceFileInfo: import/chain relationships, cycle checks, and parsing open IPython notebook cells
