- Target Roles:
Go Backend Engineering Intern·AI Agent Infrastructure & Harness Architecture Intern(Xi'an on-site or Remote · Available 4–5 days/week · 3–6+ months) - Direct Technical Pitch: Prefer a concrete technical challenge to a cover letter. Hand me a goroutine leak, a cascading cancellation race, or an AST gate that leaks edge cases, and I will trace root causes and deliver passing deterministic receipts before the day ends.

# Deterministic Evidence Probe: clone & run race detector on flagship runtime
git clone --depth 1 https://github.com/ROM4n2/agent-runtime.git && cd agent-runtime && go test -race -count=1 ./...- Zero-Hallucination (Physical Evidence Over Claims): Statements, benchmarks, and bug fixes require automated execution receipts and verifiable test outputs before landing.
- Anti-Sycophancy & Guard Clauses Flattening: Maximum two indentation levels; branch boundaries enforced early without nested logic drift.
- Local-First & Zero Leaks: Deterministic RAII/context lifetimes; fully functional offline without unvetted cloud dependencies.
