CodeAtlas previously exposed its graph mainly through CLI summaries, which made whole-project structure, file relationships, and implementation evidence difficult to inspect.

This update adds a local browser workspace and snapshot workflow with:

• project architecture and module dependency graphs
• file-level data handoff and relationship views
• directory and declaration trees with declaration-specific call identities
• AST- and docstring-grounded file guides with source-line evidence
• bundled Python and TypeScript grammars for offline use
• a double-click launcher, static demo, validation notes, and Chinese architecture documentation

Accuracy limits are shown in the UI and documentation: the data-flow view is static structural evidence rather than runtime tracing.

Validation: 127 pytest tests, Ruff lint and format checks, mypy, installed console entry point, browser/snapshot smoke tests, and a self-index of CodeAtlas with zero parse failures.
