 - **`.env` and `grapharc.toml` follow the same discovery rule: the working directory, and nowhere else.** Neither searches parent directories — a run must not be governed by a file you did not know about, and must not be *billed* to one either. **This is a behaviour change:** the credential loader used to walk up to `/`, so a `.env` in an ancestor directory (a `$HOME` one on a shared box, a client project one above a demo checkout) was picked up silently. If you relied on that, move the file into the directory you run from, `export` the variable, or pass `env_file=` to name it explicitly. A real environment variable still beats any file.
 - **`grapharc run` has no budget unless you give it one.** Set any of `--max-tokens`, `--max-iterations`, `--max-seconds`, or `--max-concurrency`; without them each dimension is unlimited and the gate admits a topology of any worst-case cost.
 
-**Verified this pass:** `pytest` → green, 2,148 selected and 13 deselected (the live ones); `ruff check .` clean; all eight `grapharc demo` stages green, plus the `trace` / `metrics` / `viz` / `replay` tour against a freshly recorded demo trace; the wheel builds and imports all submodules in a clean virtualenv with `[all]`, and `0.1.6` on PyPI is that wheel. The counts are a snapshot, not a property of the project — `pytest` re-derives them in one command, which is the only reason they are quoted, and `tests/test_deep_dive.py` fails this line rather than letting it drift.
