solana-arb-executor

Scaffolds the Rust execution hot path for Solana arbitrage: stream -> detect -> simulate -> bundle -> land, wrapped in a risk gate (caps, circuit breaker, kill-switch) and a confirm-gate. This is the on-chain layer that prior art only analyzes: agiprolabs/claude-trading-skills is Python analysis (signals, backtests, no execution), and TypeScript arb skills punt the latency-sensitive landing path. This is the genuine white space -- the part that has to be fast, correct, and safe.

Honest economics (load-bearing): spatial DEX arb on Solana is infrastructure-dominated and heavily contested; raw price gaps go to parties with better network position than a single box. A retail operator's durable edge is not raw speed -- it is correct landing (simulate-first, right CU price, tip sizing, retry discipline), risk discipline (caps/breaker/kill-switch), and less-contested opportunities (funding-basis, cross-venue rate gaps, longer-horizon plays). This is scaffolding + knowledge, not a hosted bot and not a guaranteed profit machine.

PRECEDENCE (read before any code-gen)

1. Read references/safety-rails.md FIRST. Every emitted execution path obeys it.
2. Never emit code that sends a fund-moving / signing transaction without an explicit typed human confirm-gate; no flag defeats it. Default DRY_RUN=true, REQUIRE_CONFIRM=true. Always simulate before submit.
3. Use the pinned crate versions in references/sdk-versions.md (verified 2026-06). Flag jito-sdk-rust as early 0.x.
4. Delegate program / Anchor / IDL / transaction-signing work to ../solana-dev/ via references/delegation.md. Do not duplicate it here.
5. Mandatory caps (max-notional, max-position, daily-loss) + circuit breaker + kill-switch gate every order before it can reach the confirm-gate.

Progressive disclosure

• Router (this file): pointers only -- no bulk content.
• Leaves (~60-200 lines each): dense, correct, minimal. Code lives in skill/templates/.
• Pure logic is offline-testable: templates/src/fees.rs and templates/src/risk.rs are std-only and self-contained -- run rustc --edition 2021 --test fees.rs (and risk.rs) standalone. The full crate (stream.rs, jito.rs, detector.rs, main.rs) compiles with cargo build against the pinned crates.
• Delegation: ../solana-dev/ for program / tx / signing.
