plan: batch-200 expansion (100 Pro + 100 Std)

Doubles down on what worked in batch-50:
  - dev1 (Guangzhou) is primary execution host
  - Owner cap=2 for diversity
  - --max-source-mb 200 to defend against X86-class outliers
  - Pro 2.x deprecated-board fix is already in (commit c3cac97)
  - SSH transport for dev1 -> gitea (commit 8220c99)

Candidate pool:
  200 picks from A-tier (grade>=3 & like>=10) minus already-crawled 65
  Remaining A-tier corpus is 2,741 (Pro 1326 + Std 1415)
  173 unique authors, like median 258, grade dist 4:118 / 3:82

Estimated walltime ~25-35 min on dev1 for Step 1-4 (no attachments).
LFS increment ~2.5 GB (source only) or +10 GB if Step 5 attachments
included. Either way well within Gitea's 200 GB migration threshold.

Step 5 (attachment download) deferred — not on the critical path for
EPRO2/Std → KiCad work, can revisit when license-filtered Forge
projection demands it.

+# oshwhub 扩抓批 200：执行计划
+
+**创建**：2026-04-29
+**承接**：`docs/plans/oshwhub_batch50.md`（已 100% 完结）
+**目标**：从 65 项扩到 265 项 — 验证流水线在中等规模的稳定性，开始覆盖 A 档第二梯队
+**候选清单**：`data/state/oshwhub_batch200_candidates.jsonl`（200 行）
+**主执行机**：dev1（广州，~30× 网络优势已实测）
+
+---
+
+## 1. batch-50 经验回放（影响这一批的设计）
+
+| 教训 | 这一批的对策 |
+|---|---|
+| dev1 Guangzhou 网络是关键加速器 | 全部步骤都在 dev1 跑，SG 这边只是同步消费 |
+| Pro 2.x 占高质量 Pro 池 80% | Pro 2.x parser 必须稳；deprecated-board 已修 |
+| `git push` 单次 70 MB 在 dev1 → gitea 链路 6.5% 丢包 → 360 KB/s | dev1 origin 已切 SSH 协议（commit `8220c99`），后续 push 流畅 |
+| `--max-source-mb 200` 没触发（25 Pro 最大才 9 MB）| 保留 cap 防 X86-class outlier，但预期触发率极低 |
+| `git push 2>&1 \| tail -5` 永远 exit 0 吞掉错误 | 启用 `set -o pipefail` 或检查 PIPESTATUS |
+| Pro 2.x boards[] 可能含废弃 sch/pcb 返 401 | 已修：`ticket.schematics`/`pcbs` 求交集（commit `c3cac97`）|
+| 详情 HTML 抓取是 server-render bound（~50ms / 项）| 不优化；本批 200 项 ~10s 即可 |
+
+---
+
+## 2. 候选池筛选标准（与 batch-50 一致）
+
+数据源：`data/state/oshwhub_listing_full.jsonl`（33,695 项全量索引）
+
+**硬过滤**：
+- `grade >= 3 AND like >= 10`（A 档）
+- `uuid` 不在已抓 65 项内（剩余 A 档 = 2,741 项 Pro 1326 + Std 1415）
+
+**排序**：`like*3 + star + fork*2 + views/100 + comments*2 + grade*50`
+
+**多样性约束**：
+- 单作者全局上限 2
+- Pro / Std 100:100 均衡（同 batch-50 思路）
+
+---
+
+## 3. 选出的 200 项概况
+
+| 维度 | 值 |
+|---|---|
+| 总数 | 200（100 Pro + 100 Std） |
+| 唯一作者 | 173（max 单作者 2 项） |
+| like 区间 | min=22 / median=258 / max=624 |
+| grade 分布 | 4: 118 项, 3: 82 项 |
+
+> like 中位数 258 比 batch-50 的 554 低——因为 batch-50 已经吃掉了 A 档头部。本批进入 A 档第二梯队，整体仍合格。
+
+完整名单见 `data/state/oshwhub_batch200_candidates.jsonl`。
+
+---
+
+## 4. 执行步骤
+
+> 全部在 dev1 跑。SG 端只 `git pull` 消费成果。
+
+### Step 0 — 候选池冻结 ✅
+
+`oshwhub_batch200_candidates.jsonl` 已生成。
+
+### Step 1 — 详情页扫 license（~3 min @ concurrency=5）
+
+```bash
+ssh dev1 'export PATH=$HOME/.local/bin:$PATH && \
+  cd ~/repo/FacereDataset && \
+  PYTHONUNBUFFERED=1 uv run python -u -m crawlers.oshwhub \
+    --from-jsonl data/state/oshwhub_batch200_candidates.jsonl \
+    --no-files --no-cover --concurrency 5 \
+    --out data/raw/oshwhub'
+```
+
+预期：200 项 / ~3-5 分钟（dev1 详情页 p90=73ms × 200/5 并发 ≈ 3s 网络 + server render 时间 ≈ 几分钟）。
+
+### Step 2 — license 分布盘点（无过滤入库）
+
+```bash
+ssh dev1 'cd ~/repo/FacereDataset && uv run python - <<EOF
+import json, glob, collections
+target = {json.loads(ln)["uuid"] for ln in open("data/state/oshwhub_batch200_candidates.jsonl")}
+licenses = collections.Counter()
+for p in glob.glob("data/raw/oshwhub/*/metadata.json"):
+    m = json.load(open(p))
+    if m.get("project_id") in target:
+        licenses[m.get("license") or "<unknown>"] += 1
+for lic, n in licenses.most_common():
+    print(f"  {n:>4}  {lic}")
+EOF'
+```
+
+按 batch-50 数据外推：~64% GPL 3.0、~16% Forge-friendly 自由、~16% NC variants。
+
+### Step 3 — Pro 100 项 backfill source（~10-15 min）
+
+```bash
+ssh dev1 'export PATH=$HOME/.local/bin:$PATH && \
+  cd ~/repo/FacereDataset && \
+  PRO_UUIDS=$(jq -r "select(.origin==\"pro\") | .uuid" \
+                data/state/oshwhub_batch200_candidates.jsonl | paste -sd,) && \
+  PYTHONUNBUFFERED=1 uv run python -u -m crawlers.oshwhub \
+    --backfill-pro-source \
+    --uuids "$PRO_UUIDS" \
+    --max-source-mb 200'
+```
+
+预期分布（按 batch-50 的 Pro 比例外推）：
+- Pro 2.x legacy ~80 项（chain 平均 < 30），每项 ~30s → ~40 分钟……
+
+> 等等，得拆估算：dev1 端 Pro chain 是 0.5s sleep × N + CDN 0.2s × M。粗算单项 average = 0.5×5 + 0.2×30 = 8.5s。100 项串行 = ~14 min。
+> 如果想再快可以加 backfill 路径的 concurrency（目前没加，是个小改动）。先不优化，看实测。
+
+### Step 4 — Std 100 项 backfill source（~5-10 min）
+
+```bash
+STD_UUIDS=$(jq -r 'select(.origin=="std") | .uuid' \
+              data/state/oshwhub_batch200_candidates.jsonl | paste -sd,)
+ssh dev1 ... --backfill-source --uuids "$STD_UUIDS"
+```
+
+每项 ~5-10s（Std 比 Pro 快，doc 数少），100 项 ~10 min。
+
+### Step 5 — 附件下载（**可选 / 推迟**）
+
+batch-50 的 50 项声明附件 2.36 GB；外推 batch-200 ~9-10 GB。Gitea LFS 当前用量 < 5 GB，加 10 GB 还在舒适区。
+
+但下载时间是关键因素：
+- 200 项 × 平均 50 MB 附件 / 5 MB/s（dev1 → image.lceda.cn 估算）= ~30 分钟
+- 加 `--skip-ext mp4,qt,mov` 可砍 30-50% 体积
+
+**建议**：先做 Step 1-4 拿到 license + source；附件单独评估后再决定。如果只为 EPRO2 → KiCad 训练，附件不需要。
+
+### Step 6 — 验收 + push
+
+```bash
+ssh dev1 'cd ~/repo/FacereDataset && \
+  uv run python scripts/build_index.py && \
+  git add data/raw/oshwhub/ projects.md && \
+  git commit -m "batch-200: ..." && \
+  git push origin main'
+```
+
+---
+
+## 5. 资源预算
+
+| 项 | 估算 | 备注 |
+|---|---:|---|
+| API 调用 | ~2,500 次 | 200 详情 + 100 Pro × 5 calls + 100 Std × 5 calls + chain blob 几百次 |
+| dev1 walltime（Step 1-4）| **~25-35 分钟** | 单 IP 串行；加 backfill concurrency 可压到 10-15 min |
+| 源工程体积 | **~2.5 GB** | batch-50 实测 12 MB/项 × 200 = 2.4 GB |
+| Gitea push（dev1 SSH 链路）| ~3-5 min | 同 batch-50 量级，SSH transport 健康 |
+| 附件（如做 Step 5）| +10 GB / +30 min | 可砍 mp4 节流 |
+| **LFS 总增量（不含附件）** | **~2.5 GB** | 当前 < 5 GB → batch-200 后 ~7-8 GB |
+| **LFS 总增量（含附件）** | **~12 GB** | → 批后 ~17 GB；离 200 GB 迁移线还远 |
+
+## 6. 风险与预案
+
+| 风险 | 概率 | 影响 | 预案 |
+|---|---|---|---|
+| Pro cookie 过期半路 | 低 | 100 项 Pro 可能多个失败 | 已在 dev1 + SG 同 cookie；过期表现是连续 401，监控前 5 个失败即停 |
+| 单 Pro 项目超 200 MB | 低 | size cap 触发跳过 | `--max-source-mb 200` 拦截，记 oversize state |
+| Pro 2.x 又出现新边缘 case（非 deprecated-board）| 中 | 单项 fail | 当前 fix 处理 deprecated 类；新 case 用 try/except 单点收敛后 retry |
+| 附件 mp4 视频拉爆磁盘 | 中（如做 Step 5）| 多消耗 5+ GB | `--skip-ext mp4,qt,mov` |
+| dev1 → gitea 链路波动期间 push | 中 | 需手动重试 | 已切 SSH，BBR 已开；最差 retry |
+| 触发 oshwhub 限流 | 低 | 整批中断 | 现有 sleep 已在实测水位；监控 200/non-200 比例，连续 3 个 5xx 即停 |
+
+## 7. 验收标准
+
+- [ ] `data/raw/oshwhub/` 新增 ≥ 195 个项目目录（允许 ≤ 5 项 fail）
+- [ ] 每个新增项目的 `metadata.json` 含 `license` + `source_format` + `source_path`
+- [ ] license 分布盘点写入 log
+- [ ] `projects.md` 自动重建后包含全 265 项
+- [ ] LFS 增量 < 5 GB（不含附件）/ < 15 GB（含附件）
+- [ ] log.md 顶部一条总结性日志
+- [ ] dev1 push 整批 ≤ 10 min wall
+
+## 8. 后续候选
+
+- **batch-500** —— 把 A 档（2,741 项）一次性吃完（剩 ~2,540）
+- **B 档（grade≥2 & like≥5）扩量** —— 总池子 ~6,243 项
+- **附件细分策略** —— 按 ext 分类 LFS（Gerber/STEP 留、视频走外链）
+- **Pro 2.x → KiCad 解析链路** —— 复用 `easyeda2kicad.py`（plan.md §1.7 提过但未做）
+- **license 详情扫全 A 档** —— 全 2,806 项 license 落本地，给所有未来批选作过滤依据
