+## Fixed
+
+### Dependencies - FastAPI Compatibility
+
+- **FastAPI Upper Bound** — Pinned `fastapi` to `>=0.136,<0.137` to prevent breakage from FastAPI 0.137+
+  which introduced incompatible changes with the current codebase.
+
+## Refactored
+
+### Tooling - Testing Execution Model
+
+- **Removed Parallel Behave Settings** — Deleted `parallel = 8` and `parallel_scheme = "multiprocessing"` from
+  `[tool.behave]` in `pyproject.toml`. Tests now run sequentially by default, aligning with the BDD convention
+  of isolated scenarios.
+- **Updated AGENTS.md** — Refreshed quick commands and dev setup instructions.
+- **Documentation Alignment** — Brought `docs/getting-started/project_structure.md` in sync with current layout.
