Summary

• MemoryIndexManager.readFile now catches ENOENT and returns { text: "", path } instead of throwing, so the memory read tool degrades gracefully when a file doesn't exist yet (e.g. a daily log that hasn't been created).
• Adds an e2e test covering the ENOENT → empty-text path.

Closes #9307

Test plan

• Existing memory-tool.e2e.test.ts suite passes
• New "returns empty text without error when file does not exist (ENOENT)" test passes
• Manual: delete a daily memory log, invoke the read tool — should return empty text, no error

Greptile Summary

Changed MemoryIndexManager.readFile to catch ENOENT errors and return { text: "", path } instead of throwing, allowing the memory read tool to degrade gracefully when files don't exist yet (e.g., daily logs that haven't been created)

• Added try-catch block around fs.lstat call in manager.ts:440-452
• Returns empty text with path when file is not found, instead of throwing error
• Added e2e test case to verify ENOENT handling returns empty text without error
• Existing error handling for other file system errors (permissions, invalid paths) remains unchanged

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The change is a focused error handling improvement with proper test coverage. It follows established ENOENT handling patterns in the codebase, degrades gracefully by returning empty text rather than throwing, and includes an e2e test that validates the new behavior. The modification is minimal and well-contained.
• No files require special attention
