check

Run environment and capacity preflight checks before heavy operations.

Usage

openalex-snapshot check --root-dir . --dataset all

What it checks

• dependency binaries (aws; DuckDB is no longer required — parquet I/O is pure Rust)
• path writability for root/parquet/metadata
• download disk requirement (parquet manifest.json size + safety margin)

Options

• --strict fail on warnings as well as failures
• --json machine-readable output
• --precise enable precise source inventory estimate
• shared runtime args: --dataset, --workers, --max-memory-mb
