Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.

- 2026-08-20T05:43:51Z
Contract
- createVirtualFileSystem initializes an in-memory file system with initial file tree and verifies file existence
- readFile retrieves exact file content and returns undefined for nonexistent files
- writeFile creates new files, overwrites existing files, and creates intermediate directories
- removeFile deletes files from virtual file system and updates accessible entries
- directoryExists and getAccessibleEntries inspect hierarchical directory structures
Files
- PROMPT.md
- csx.json
- package-lock.json
