Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for firmware images, partition tables, boot chains, update packages, extracted filesystems, embedded configs, and device-facing trust boundaries. Use when the user asks to unpack firmware, map partition layout, inspect bootloader or init chains, recover update keys or credentials, trace config loading, or explain how a device surface reaches the decisive artifact. Use only after `$ctf-sandbox-orchestrator` has already established sandbox assumptions and routed here.

# Competition Firmware Layout

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 understanding how a firmware image is structured, booted, updated, and turned into reachable device behavior.

Reply in Simplified Chinese unless the user explicitly requests English.

## Quick Start

1. Preserve the original image, extracted partitions, unpacked filesystems, and patched copies as separate artifacts.
2. Map outer container, partition table, bootloader, kernel, rootfs, config, and update metadata before editing anything.
3. Track the boot or update chain in order instead of jumping straight to the most interesting file.
4. Record keys, signatures, offsets, partition boundaries, and init entrypoints in one compact evidence chain.
