mnemon-harness beta review notes

The mnemon project has released an experimental beta called `mnemon-harness`, a separate source-built track for project-local host-agent lifecycle state that is not production-ready and has no compatibility guarantee. The beta explores commands for lifecycle event logging, projection surfaces, coordination topology events, and a TUI review console, while explicitly excluding production readiness, automatic apply, and full multi-agent runtime. The release branch is intentionally public-safe, omitting internal planning and raw validation artifacts.

This is a temporary personal note for beta review context, not a roadmap.

mnemon-harness

is an experimental beta for project-local host-agent lifecycle state. It is source-built, separate from the stable mnemon

CLI, not production-ready, and has no compatibility guarantee. Commands, file layouts, schemas, projected surfaces, and behavior may change in breaking ways before a stable release.

Mnemon is a local, LLM-supervised persistent memory CLI for host agents. The stable mnemon

CLI focuses on memory operations such as setup, remember, link, recall, search, status, and retention.

mnemon-harness

is a separate experimental beta track in the same repository. It explores project-local lifecycle state around host agents without replacing those hosts. The release branch is intentionally public-safe: internal planning, raw validation artifacts, generated site HTML, and detailed future plans are not part of the beta branch.
