Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for parser differentials, HTTP normalization gaps, ambiguous headers, path decoding drift, transfer-framing mismatches, and request smuggling routes. Use when the user asks to trace proxy and backend parse differences, conflicting path normalization, Host or forwarded-header ambiguity, CL/TE issues, or routing outcomes that differ across hops. Use only after `$ctf-sandbox-orchestrator` has already established sandbox assumptions and routed here.

# Competition Request Normalization Smuggling

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 request interpretation changes between proxy, middleware, and backend parser layers.

Reply in Simplified Chinese unless the user explicitly requests English.

## Quick Start

1. Map every parsing hop: client-facing proxy, gateway, app server, and downstream service.
2. Record path normalization, header canonicalization, transfer framing, and host derivation at each hop.
3. Capture one accepted baseline request and one differential request with minimal delta.
4. Prove which hop interprets the request differently.
