Provider Mux & Launcher Implementation Plan

Status

This file is archived historical context from the April 19, 2026 planning pass. Do not use it as the active operational source for amux-proxy.

The current runtime truth for this path now lives in:

• packages/transport-mux/README.md
• packages/transport-mux/migration.md
• packages/transport-mux/architecture.md

Why this file was retired

The original plan described an active implementation track for a separate proxy package and related packaging/container work. The launcher path in this repo now resolves through the JS transport-mux package instead, so keeping the earlier plan in the active operational path created split runtime truth.

What remains useful here

• historical sequencing context for the early provider-mux rollout
• evidence of the earlier task breakdown and naming
• background for why the runtime and publication surfaces later needed convergence cleanup

Operator note

When checking the current cutover state, use the transport-mux package docs and their verification commands. Treat any implementation details that used to appear in this archived plan as historical unless they are restated in the active transport-mux docs.
