 ## Pi: subagents no longer inherit project AGENTS.md / CLAUDE.md
 
 While fixing the spawn path we found that Pi appends project context files (`AGENTS.md`, `CLAUDE.md`) to a custom system prompt unless told not to. Magic Context's hidden subagents are focused one-shot workers with purpose-built prompts; your project's agent instructions were being silently appended to all of them. Subagent spawns now pass `--no-context-files`, so the historian, dreamer, and sidekick receive exactly the prompt they were designed with. You may notice slightly different historian output on Pi as a result — that is the prompt getting cleaner, not a regression.

+## `dreamer.inject_docs: false` works again
+
+Setting `dreamer.inject_docs` to `false` no longer silently does nothing (#210). When the `<project-docs>` block moved from the system prompt into the cached history baseline a few releases ago, the setting was left gating the old, retired path — so `ARCHITECTURE.md` and `STRUCTURE.md` kept being injected regardless of the config. The flag now gates the real injection site on both OpenCode and Pi. It is independent of whether the dreamer itself is enabled: if you maintain those files by hand but don't want them in context, `inject_docs: false` now honors that. Changing the setting mid-session takes effect on the next natural context rebuild rather than forcing an immediate one.
