 ### Conventions to preserve
 
-- **Dry-run semantics:** any G1-mutating endpoint takes a `dry_run` flag; `G1Client._post` short-circuits and logs `[DRY-RUN]` instead of hitting the network. `auto_grid` keeps `dry_run=True` by default (the G1 DDS has been unstable). Never silently strip dry-run from a mutating path.
+- **Dry-run semantics:** any G1-mutating endpoint takes a `dry_run` flag; `G1Client._post` short-circuits and logs `[DRY-RUN]` instead of hitting the network. Never silently strip dry-run from a mutating path.
 - **Per-request client construction** (via `api/_deps.py`) is intentional — runtime `PUT /api/config` updates would otherwise be invisible.
 - Endpoints return `{ ..., "timings_ms": {step: ms, ..., total: ms} }`. New endpoints should follow this with `Stopwatch().step(name)`.
 - Calibration paths in config (`calibration.file`, `calibration.samples_file`) are resolved against `PRESA_MANO_DATA` when relative — see `_deps.calibration_file_path()` / `samples_file_path()`.
