- runtime-mcp.mdx: add Environment variables table documenting MOLECULE_MODEL
(canonical), MODEL (alias), and MODEL_PROVIDER (deprecated). Warns that
MODEL_PROVIDER was misnamed and caused production incidents.
- runtime-mcp.mdx: add HTTP/SSE transport section for Hermes workspaces —
a2a_mcp_server.py now exposes --transport=http with POST /mcp, GET /mcp/stream,
and GET /health endpoints.
- changelog.mdx: add 2026-05-10 entries for #280 (MODEL_PROVIDER deprecation),
#291 (delegate_task self-deadlock guard), and #5 (HTTP/SSE Hermes transport).
Closes: molecule-core#280, molecule-core#291, molecule-ai-workspace-runtime#5
