 ### Changed
 - **Copilot Studio Core Concepts Overview deck refreshed to the latest version** (`presentations/advanced-agent-in-a-day/02. Copilot Studio Core Concepts_AIAD.pptx`, Git LFS). Updated the slide deck backing the `copilot-studio-core-concepts-overview` module (used by the *Advanced Agent in a Day* workshop). Filename and module `slides:` path are unchanged, so no references needed updating.
+- **Orchestration & Dynamic Chaining deck refreshed to the latest version** (`presentations/bootcamp/09. Orchestration and Dynamic Chaining Concepts_CB.pptx`, Git LFS). Updated the slide deck backing the shared `orchestration` module — used by both the *Advanced Agent in a Day* workshop and the *Architecture Bootcamp*. Filename and module `slides:` path are unchanged, so no references needed updating.
 - **Agenda rows now show a Level pill consistently on modules *and* labs.** In `_layouts/event.html`, `type: module` agenda rows previously rendered only a duration pill, while lab rows rendered both a Level and a duration pill — so on every event/workshop agenda the level looked sporadic (present on labs, absent on modules). Module rows now render a `Level {{ mod.difficulty }}` pill alongside duration, matching lab rows. Applies to all agendas (Advanced Agent in a Day, Bootcamp, MCS in a Day, Agent in a Day). All `_modules/*.md` already carry a numeric `difficulty`, so every module row now shows its level.
 - **Tools module (`tools-overview`) promoted to level 300** (was 200), aligning it with its already-300 companion lab (`mcs-tools`). Affects every agenda that uses the module — the new *Advanced Agent in a Day* workshop and the *Architecture Bootcamp*.
 - **Copilot Studio Plugin / Skills module (`copilot-studio-plugin`) promoted to level 300** (was 200). Affects every agenda that uses the module — the new *Advanced Agent in a Day* workshop and the *Architecture Bootcamp*.
