Motivation & Context

The harness sample overview describes file memory as an optional MemoryContextProvider enabled by passing memory_store. The current factory adds FileMemoryProvider by default and exposes file_memory_store and disable_file_memory instead.

Description & Review Guide

• What are the major changes? Correct the feature-table entry and document the default store root, custom-store parameter, and disable flag.
• What is the impact of these changes? Documentation only. It describes the existing factory configuration without changing memory, storage, or runtime behavior.
• What do you want reviewers to focus on? Agreement with the current create_harness_agent signature and file-memory provider assembly. Static source/documentation checks were performed; no harness run, filesystem behavior test, build, or model call was executed.

N/A - trivial change. This corrects stale provider and configuration names and documents defaults already specified by the existing factory.

What changed in this PR

Corrects the harness sample’s file-memory guidance to match the existing factory configuration. This is documentation-only; runtime behavior is unchanged.

Changes:

• Replaces the stale provider name with FileMemoryProvider and clarifies that it is enabled by default.
• Documents the default {cwd}/agent-file-memory store root, file_memory_store parameter, and disable_file_memory flag.
