A2a Meta Clones

Canonical policy (binding): This repo is orchestrated by A2A-Meta (sibling of !A2A-Meta-Repos/). See A2A-Meta/docs/repo_topology.md for the relationship, and A2A-Meta/docs/clone_repo_architecture_v0_DRAFT.md for the spec this repo implements.

A2A-Meta/docs/repo_topology.md is the canonical policy document. This README is a convenience mirror, not a second authority. If they conflict, the root side wins.

Deployable MCP clone services for A2A-Meta. Hosts 3 Railway service slots (slot-a, slot-b, slot-c) for the 5 PENDING_CLONES MCP clones catalogued in A2A-Meta/api/middleware/live_clone_catalog.py.

The catalog in A2A-Meta is the single source of truth for which clones are LIVE. This repo vendors a snapshot (via sync_catalog.py) and serves the clones via the multiplexer vendored from A2A-Meta/api/multiplexer.py.

Status (Phase A — local scaffold)

• Phase A (local scaffold): in progress, see docs/parallel_prep_runlog.md (mirror) and A2A-Meta/docs/a2a_meta_clones_v1_implementation_plan_v0_DRAFT.md (canonical plan)
• Phase B (GitHub + CI): not started
• Phase C (Railway provisioning): not started
• Phase D (deploy + promotion): not started
