+## The 30-second pitch
+
+Frontier-class agent behavior is not exclusively a function of model size. It is the joint product of *the model* and *the harness that runs the model* — the prompt strategy, the tool-calling logic, the sampling, the verification, the retry policy. Today, that harness is hand-tuned by senior staff at every serious AI lab. **Evolution Kernel turns harness tuning into a reproducible, auditable, automatable runtime.** Point it at a target repo, give it a measurable goal, walk away. Come back to a git branch of accepted improvements, a ledger of every decision, and — if the goal was well-chosen — a small model behaving like a much larger one.
+
+| | What this unlocks |
+| --- | --- |
+| 💰 **Economics** | Frontier API calls (GPT-5.5, Claude Opus 4.7) cost $$ per task. A 3 B-active open-weight model running locally costs fractions of a cent. Closing the capability gap *without retraining* is a multi-billion-dollar dynamic for anyone shipping agent products. |
+| 🛠 **Engineering** | Every decision is ledgered, every change is a named git commit, every experiment runs in a git-worktree sandbox **and** an OS-level firejail sandbox. This is a runtime you can put in production, not a research demo. |
+| 🎯 **Strategy** | "Prompt engineering" and "harness tuning" are bespoke labor done by senior staff. This loop makes them reproducible, transferable, and compoundable. |

-### $34. One night. An 8B model that runs on a MacBook — from 51.8% to 96.2% on elementary math. Zero weight changes.
+**Why this benchmark.** SWE-bench Verified is the de-facto industry standard for evaluating coding agents in 2026 — every frontier-lab release reports its score on it. 500 real GitHub bug-fix tasks, vetted by human annotators. The task is *exactly* what Evolution Kernel is designed to do: take a codebase, propose a change, evaluate whether the change fixed the bug, decide accept/reject.
-> Qwen3-8B-Instruct is a general-purpose model with no math-specific training. Its weights are frozen throughout. Evolution Kernel evolves only the solver harness — prompt strategies, tools, and sampling logic. After one overnight run, the same model sits 2.8 points behind GPT-5.5. That means every child can have a free, local, always-on, privacy-safe math tutor.
+**Why this model.** [Qwen3.6-35B-A3B](https://qwen.ai/blog?id=qwen3.6-35b-a3b) is Alibaba's flagship open-weight model (Apache 2.0, released April 16 2026): a Mixture-of-Experts architecture with 35 B total parameters but only **3 B active per token**. It runs on a single consumer GPU. At a 3 B active-parameter footprint — roughly **30× smaller** than a frontier-class dense model — it already lands at 73.4 % on SWE-bench Verified, **within 15 points of GPT-5.5 while costing fractions of a cent per task to run locally**.
-```
- GSM8K pass rate (1,319 math word problems)
- GPT-5.5 ████████████████████ 99.0%
- Claude Opus 4.7 ████████████████████ 98.6%
- ─────────────────────────────────────────────────────

- Qwen3-8B baseline ██████████░░░░░░░░░░ 51.8% ← raw model, naive prompt
-```
+**The thesis.** That 73.4 % is the result of months of hand-tuned harness engineering by the Qwen team. Closing the remaining gap to GPT-5.5 (88.7 %) is exactly the kind of work Evolution Kernel automates — the planner converges on better tool selection, parallel sampling, verifier loops, and error-pattern recovery. Same model, same weights, evolved harness.

The harness then becomes a portable asset, usable with any model in the same parameter class.

-### $34，一晚上，一个能在 MacBook 上跑的 8B 模型——小学数学应用题正确率 96.2%，和 GPT-5.5 基本同档。模型权重一字节未动。
+**为什么选这个 benchmark。** SWE-bench Verified 是 2026 年评估 coding agent 的事实标准——每家旗舰实验室发新版都报这个分。500 道真实 GitHub bug-fix 题，由人类标注者验证。它的任务和 Evolution Kernel 的本职 *完全对口*：拿到一份代码、提出一个改动、判断改动是否修好了 bug、决定接受 / 拒绝。
-> Qwen3-8B-Instruct 是一个通用模型，没有专门的数学训练。权重全程冻结。Evolution Kernel 只进化 solver harness——提示策略、工具调用和采样逻辑。一个隔夜跑完，同一个模型只落后 GPT-5.5 2.8 个百分点。这意味着每个孩子都能拥有一个免费、本地、随时在线、完全保护隐私的数学辅导老师。
+**为什么选这个模型。** [Qwen3.6-35B-A3B](https://qwen.ai/blog?id=qwen3.6-35b-a3b) 是阿里 2026-04-16 发布的开源旗舰（Apache 2.0）：35 B 总参 Mixture-of-Experts 架构，**每 token 只激活 3 B**。一张消费级 GPU 就能跑。3 B 激活参数足迹——比旗舰稠密模型**小约 30 倍**——在 SWE-bench Verified 上已经做到 73.4%，**距离 GPT-5.5 只差 15 分，而本地推理成本是每任务几分钱**。
-```
- GSM8K 通过率（1,319 道小学数学应用题）
- GPT-5.5 ████████████████████ 99.0%
- Claude Opus 4.7 ████████████████████ 98.6%
- ─────────────────────────────────────────────────────
- Qwen3-8B + 我们 ███████████████████░ 96.2% ← $34 一晚上跑出来的
- ─────────────────────────────────────────────────────
- 早期 GPT-4 ██████████████████░░ 92.0%
- Qwen3-8B 基线 ██████████░░░░░░░░░░ 51.8% ← 原始模型，朴素提示
-```
+**核心论点。** 那 73.4% 是 Qwen 团队几个月人肉调 harness 的成果。把剩下到 GPT-5.5（88.7%）的差距闭合，恰好是 Evolution Kernel 自动化的工作——规划器会收敛到更好的工具选择、并行采样、验证器循环、错误模式恢复。同一个模型，同一份权重，进化后的 harness。

+
+诚实交代 v1.0 *还不能* 做什么。
+
+- **评估器是 LLM。** 可能被一个"看起来对但实际不对"的 patch 骗到，或者拒掉一个"对但写法陌生"的 patch。用 `goal_evaluator` + `evidence_sources` 里的强程序化门控把 LLM 判断锚定到 ground truth。
+- **沙箱只管文件系统。** firejail 拦下 worktree 之外的写。它**不**拦网络、不拦 fork bomb、不拦进程注入。要跑不信任的执行器，外面再套 network namespace 或 VM。
+- **历史是摘要，不是回放。** 规划器只看到最近 *N* 轮的一行 reflection，不看完整的过往 plan。长时程策略需要规划器把状态自己编码进 `plan.json` 的 summary。
+- **成本会累积。** 30 轮循环用 Claude Sonnet 规划 + Claude Code 执行可能花 $40–$100。Hard-stop 预算是真的——设得比你预期还低。
+- **真实 provider 集成不在 CI 上。** 99 个测试用 `tests/fixtures/` 的 fixture 脚本。端到端的 Aider / Claude Code / Anthropic / OpenAI 集成是每个 release 前手测，不是每次 push 都跑。
