Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for race windows, ordering bugs, idempotency failures, lock gaps, concurrent worker drift, and state inconsistencies that produce decisive effects. Use when the user asks to reproduce timing-sensitive bugs, concurrent state corruption, duplicate actions, stale reads, or privilege or balance drift caused by request ordering. Use only after `$ctf-sandbox-orchestrator` has already established sandbox assumptions and routed here.

# Competition Race Condition State Drift

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 decisive behavior depends on request timing, async ordering, lock gaps, or stale state.

Reply in Simplified Chinese unless the user explicitly requests English.

## Quick Start

1. Identify mutable state first: rows, cache keys, queue payloads, session fields, counters, or files.
2. Reproduce with smallest concurrent sequence and fixed timing assumptions.
3. Capture one baseline run and one racing run with only one variable changed.
4. Track read, check, write, enqueue, and commit boundaries separately.
