Competition File Parser Chain

Use this skill only as a downstream specialization after $ctf-sandbox-orchestrator is already active and has established sandbox assumptions, node ownership, and evidence priorities. If that has not happened yet, return to $ctf-sandbox-orchestrator first.

Use this skill when the hard part is following a file from ingress through every parser, extractor, converter, or deserializer boundary that matters.

Quick Start

1. Preserve the original upload and every derived artifact separately.
2. Map the chain in order: ingress, temp storage, archive extraction, format conversion, parser call, deserialization, and final consumer.
3. Record filenames, MIME guesses, extensions, temp paths, and parser choices before mutating anything.
4. Separate client-visible validation from backend parser behavior.
5. Reproduce the smallest file-processing chain that yields the decisive branch or artifact.
