@chestnutlabs/gcode-containers

Safe, bounded, zero-dependency container extraction for sliced G-code archives — .gcode.3mf (sliced-plate export) and plain ZIP — for the Chestnut Labs G-code Preview stack (design: DD-005, security review DD-005 §7.3).

• In-memory ZIP reader with strict resource limits (entry counts, sizes, name policies)
• .gcode.3mf plate discovery and selection (multi-plate via the wire plate option)
• Hardened against adversarial archives — a manifest-tracked adversarial corpus rides in CI, and coverage-guided fuzzing over readDirectory/streamEntry is part of the release gate

This package is bundled into the parser's default batteries worker — most applications never import it directly. Import it to build a custom worker or to consume containers outside the parse pipeline.
