 - [What does “the agent proposes; the runtime decides” mean?](https://traverse-framework.com/questions/what-does-agent-proposes-runtime-decides-mean.html): boundary in one page — agents search/plan/suggest; runtime validates, executes or denies, leaves a trace.
 - [What is one shared runtime.wasm?](https://traverse-framework.com/questions/what-is-one-shared-runtime-wasm.html): embedders are clients; honest consumer list.

+- [Agent speaks MCP. Exact pin kills the freestyle.](https://traverse-framework.com/blog/agent-mcp-exact-ref.html): v0.14.0 weekly demo — an agent calls MCP-shaped tools (façade over `ExactModelBrowserHost` under Node, not the Mode A `traverse-mcp` binary) against the signed `digits-mlp-1.0.0` package; Browser + Node bit-identical; tamper → `digest_mismatch`, empty trust → `key_untrusted`, rights lie → `rights_mismatch`; test-only key (prod signing #1567). Not catalog `model.execute`. Not Hugging Face.
 - [Signed model. Exact pin. Bit-identical hosts.](https://traverse-framework.com/blog/signed-exact-ref-digits.html): v0.14.0 weekly demo — signed `digits-mlp-1.0.0` exact-ref package, same bytes on Browser + Node (`ExactModelBrowserHost`); tamper → `digest_mismatch`; test-only key (prod signing #1567). Not catalog `model.execute`. Not Hugging Face.
 - [Same WASM. Browser and Node match. Agent still can’t freestyle.](https://traverse-framework.com/blog/same-wasm-multi-host.html): v0.13.0 multi-host — identical `core.authorize@1.2.0` bytes on Browser + Node; agent treasury cheat still denied.
