Appends one cell to a run's or a dataset's decision record — why a source was chosen, what a check found, what you changed and why. The record is append-only and is what a reader sees beside the data. Write one for every decision worth explaining. Example: {"run_id": "…", "heading": "Dropped the 2019 station file", "markdown": "The 2019 export repeats each hour twice; the API covers the same range cleanly, so the recipe reads the API for every year.", "phase": "acquire"}. Exactly one of run_id or dataset_id. Reusing a cell_id revises that cell in place. Returns {cell_id, sequence}. Costs nothing and builds nothing.
