`[2026-06-15]` **Memory provider LIVE-PROVEN against personal v0.35.3; recall-injection is upstream.** worldtree-dev's Tier-3 promotion recipe: memory-call fires from Tier-3 PROMOTION, gated at `service.py:2623` on `ctx.kind=="consumer_defined"` AND `ctx.memory_config is not None` (agent DEFINED WITH a `memory` block, dim 1024) AND handshake-granted memory caps AND `embedding_dim==1024`. Binding = `POST /sessions BifrostBindingRequest{endpoint_url}`, handshake `caps=["affect","memory"]`, **`binding.scope` null** (per-op scopes auto-minted). A `BIFROST_CLIENT_ALLOWED_HOSTS` allowlist gates the endpoint (infra-ops added `:8391`). HTTP + HS256 both work in dev.
