+/**
+ * Scenario: the **session skill catalog** — loading the skills available in
+ * the current directory and inspecting where each one came from.
+ *
+ * Concept taught: the skill domain is split across scopes by state identity.
+ * `IGlobalSkillCatalog` (App) holds the process-wide set — code-defined
+ * builtins plus user / brand skills discovered from the home directories — and
+ * is loaded once; `ISessionSkillCatalog` (Session) merges that global set with
+ * the project skills discovered from the session's current `workDir`
+ * (`ISessionWorkspaceContext` ← `IExecContext.cwd`), reloading when the
+ * workDir changes. Every `SkillDefinition` carries a `source` tag
+ * (`builtin` | `user` | `extra` | `project`), so the catalog can report
+ * *provenance* — which layer and which directory a skill came from — not just
+ * its name.
+ *
+ * This example boots the production `startUpFileSystem` composition root so the
+ * catalog reads real `SKILL.md` files from disk through the filesystem
+ * `ISkillCatalogStore`, opens one Session scope rooted at `process.cwd()`, and
+ * prints every merged skill together with its `source` and path.
+ * `IPluginService` is seeded as an empty stub so the slice stays focused on the
+ * builtin / user / project layers and contributes no plugin skills.
+ *
+ * Run:
+ *   pnpm --filter @moonshot-ai/agent-core-v2 example -- examples/session-skill.example.ts
