+## 三之五、条件分支（`when` ＋ `on_dep_fail`）
+
+节点加 `when` 子句就变成有条件的节点：条件全成立才放行，任一被证伪直接 `skipped`。
+
+    {"id": "B", "deps": ["A"], "deps_rule": "all_done",
+     "when": [{"node": "A", "status": "done"}]}
+    {"id": "C", "deps": ["A"], "deps_rule": "all_done",
+     "when": [{"node": "A", "status": "blocked"}]}
+
+`A` 成了走 `B`、`A` 败了走 `C`，就是这样写出来的。判「成 / 败」用 `deps_rule: all_done`（`blocked` 也算有定论），用默认的 `all_success` 会先卡在依赖上。
+
+上游跑不成时下游怎么办，由 `on_dep_fail` 决定，三档：
+
+1. `wait`（默认）—— 停在待办里等，与旧行为一致。
+2. `skip` —— 连坐跳过，一路往下跳。
+3. `block` —— 整枝停住，进 `blocked`（`blocked_by: dep`）。
+
+`skipped` 是终态：不会再被派活、不算进进度分母、下游按 `on_dep_fail` 继续传。
+
+## 三之六、子图
+
+节点内部再拆流程，用 `subgraph` 内联写，展开成 `<父id>/<子id>`：
+
+    {"id": "P", "domain": ["docs/"], "subgraph": {"nodes": [
+        {"id": "s1", "accepts": ["文档写完了"]},
+        {"id": "s2", "deps": ["s1"], "accepts": ["索引登记了"]}]}}
+
+规则四条：
+
+1. 子节点 id 自动加 `<父>/` 前缀，内部 `deps` 也跟着映射过去，所以子图里怎么写 `deps` 都行。
+2. 子节点**默认继承父节点域**（子流程通常写同一块）；要分片就用 `subgraph.child_domain`，支持 `{id}`。
+3. 父节点展开后进 `gating`，子节点全 `done` ⇒ 父 `done`；子节点全定下来但有不满意的 ⇒ 父 `blocked`（`blocked_by: child_failed`）。
+4. `map` 与 `subgraph` 只能选一个，同时写直接报错。
+
+`subgraph` 里还能再套 `subgraph`，前缀会一层层叠上去。
+
+## 三之七、人审节点与取消
+
+人审：节点写 `"approval": true`，回报 `done` 后不进 `done`，而是进 `awaiting` 等人过目：
+
+    python graph/graphctl.py approve --ws "<ws>" --gid "<gid>" --node A --by user
+    python graph/graphctl.py approve --ws "<ws>" --gid "<gid>" --node A --reject --reason "不合格"
+
+通过 ⇒ `done`（记 `approved_at` / `approved_by`）；驳回 ⇒ `blocked`（`blocked_by: rejected`）。下游在 `awaiting` 期间一律不派。
+
+取消：`cancelled` 是终态，会连坐子节点：
+
+    python graph/graphctl.py cancel --ws "<ws>" --gid "<gid>" --node P --reason "改需求"
+    python graph/graphctl.py cancel --ws "<ws>" --gid "<gid>" --all
+
+已经 `done` 的节点不被取消（结果不能撤回）。下游按 `on_dep_fail` 处置，配 `skip` 就整枝跳过。
+
+## 三之八、自动派活与排期
+
+`tick` 是「算完就开」：一次调用把超时回收、展开、条件判定推到不动点，再按就绪集直接把节点开成 `running`。
+
+    python graph/graphctl.py tick --ws "<ws>" --gid "<gid>" --by tick [--limit N] [--dry-run]
+
+输出 `started`（这次开了谁）、`missed`（算的时候还行、写的时候被别人改了，通常为空）、`ready_now`（下一批）、`slots`（还剩几个名额）。
+
+`plan` 给上层排期用，出的一行已经把四条硬规则写成规范形态：
+
+    python graph/graphctl.py plan --ws "<ws>" --gid "<gid>" [--scope "<线名>/"] [--after-sec 240]
+
+1. `cwds` —— 正斜杠绝对路径。
+2. `workspace_scope` —— 线名加尾斜杠，默认取工作区目录名。
+3. `next_run_at` —— 毫秒 epoch。
+4. `scheduled_at` —— ISO 本地时间。
+
+`plan` 只产出行，**不写宿主库** —— 图模式零侵入这条不变，落库由上层一条命令完成。
+
+## 三之九、按域分池与进度
+
+分池：同域并发单独限流，与 `max_parallel` 叠加生效。
+
+    python graph/graphctl.py init ... --pool "docs/ui/=1" --pool "server/=2"
+    {"pools": {"docs/ui/": 1}}       # 写进 nodes-json 也可以
+
+判定用的是域前缀重叠：节点域 `docs/ui/a/` 落进 `docs/ui/` 这个池。
+
+进度与关键路径：
+
+    python graph/graphctl.py progress --ws "<ws>" --gid "<gid>"
+
+输出 `total` / `by_status` / `percent`（分母排除 `skipped` 与 `cancelled`）、`blocked` / `awaiting`、`critical_path`（**未完成节点之间的最长依赖链**，告诉你哪条链决定工期）。
+

 测试对 `graphctl.py` 的唯一要求是「能当命令行跑」，不 import 它的内部函数 —— 所以改内部实现不会连带改测试。
 
 ## 六、还没做的（下一步）
 
-- 自动派活：读 `ready` 后自动建排期（要复用现有排期硬规则：cwds 正斜杠、workspace_scope、next_run_at 毫秒、scheduled_at ISO）。
 - 判定节点完成：现在靠回报 `--state done`，还没有「看证据够不够」的自动判定。
 - 回退边：`attempts` 与重试已在记，但还没有「判不过回到某个上游节点」的字段（现在的回退只有"自己重试"）。
 - 展开源变化：`map.from` 只在上游 `done` 之后读一次，上游重跑（回退）不会重新展开。
+- 排期落库：`plan` 只出规范行，写进宿主排期表由上层完成。
+- 跨图子图：现在子图只能内联，还不能引用另一张图。
 
 这几件都只在本目录内加，不影响现有机制。
