 - **Subscription boundary:** the *primary* never sets `ANTHROPIC_BASE_URL` (stays on
   Pro/Max). Only the *secondary* process is off-subscription — and `bridged` itself is a
   plain daemon (no Anthropic quota), so it may poll/subscribe freely.
-- **Symmetric 2-way:** herdr can inject a turn into *either* pane (typing keystrokes is
-  subscription-safe), so primary→worker and worker→primary use one mechanism.
+- **How the primary consumes a reply:** a single **blocking request** (`bridged` holds the
+  HTTP call open until the worker's turn completes, then returns the reply as the body). No
+  cross-turn busy-poll, so no quota burn. SSE is an optional side-channel for humans/dashboards
+  watching status, not how the primary gets its answer. Long/detached work uses the async
+  broker path instead.
+- **Worker → primary:** *single-host only*, herdr can also type into the primary pane (typing
+  keystrokes is subscription-safe). When the primary runs off-herdr (e.g. on a Mac,
+  split-host), that direction goes via the **broker + the primary's own `Stop`-hook** —
+  `bridged` cannot inject into a primary it doesn't host. See the wiki for the two topologies.
 - **Different model per process** sidesteps Claude Code's lack of per-subagent provider
   routing — the worker isn't a subagent, it's its own configured process.
 - **AgentAPI** ([`coder/agentapi`](https://github.com/coder/agentapi)) is retained only as a
