feat(curator): deploy the phase-0 system prompt, and correct a misleading README figure

The workspace now holds .pi/SYSTEM.md and .pi/APPEND_SYSTEM.md and nothing else. SYSTEM.md is rewritten for what is actually deployed. The version committed in 07dd648 described five tools that will not exist until phase 3; shipping it would have invited the model to call tools it does not have. The capability section now states plainly that the agent has no tools and that every fact arrives in the request. The phase-3 target, including the full tool-bearing launch contract, is recorded in the plan as §4b together with why each part cannot be enabled sooner. profile.toml likewise describes the deployed configuration rather than the target, so that deploy-scenario.sh validates against reality and the path check means something. Recovered from the retired SKILL.md and folded into SYSTEM.md: the rule that the current request's schema and length limits override everything else, and that a JSON task returns exactly one JSON value with no fences. Phase 0's four prompt types all depend on it, and it was the one part of that file not already covered. Measured before and after on the real workspace, with flags read from the code rather than transcribed (docs/evidence/2026-08-27-curator-phase0-prompt.md): - expert coding assistant framing: present -> gone - pointer to pi's own documentation: present -> gone - the 64-line media policy: absent -> present - workspace AGENTS.md: loaded -> blocked - parent-directory AGENTS.md: LEAKED -> blocked - <available_skills>: absent both times Two things this confirms on the production configuration rather than a synthetic probe. --skill was genuinely a no-op: it pointed at a real 64-line SKILL.md and the skills block was still absent, because pi emits it only when a tool named read is active and --no-tools deactivates everything. And --no-context-files is the only switch that stops parent-directory pollution: a marker planted in /home/claw/pi-workspaces/AGENTS.md reached the prompt before and not after. Deleting the now-dead AGENTS.md and SKILL.md from the workspace changed the prompt length by zero bytes, which is the proof that they were dead. README corrected. Its table cited 960 characters as Curator's system prompt after the change; that figure came from a few-line stub SYSTEM.md in the isolation probe, and the real prompt is 3539 -- larger, not smaller. Presenting the stub measurement as Curator's was misleading, and "72% smaller" was wrong. The prompt grew because roughly 1.9 KB of pi scaffolding was replaced by domain policy that had never loaded at all. The mechanism claim is unaffected.

+The prompt got *larger*, and that is the fix rather than its cost: of the
+original 2548 characters roughly 1.9 KB was pi's coding-assistant scaffolding and
+a pointer telling the agent to read pi's documentation and follow its
+cross-references — noise for a media agent, and a ready-made escalation path for

+## 三个结论
+
+**1. `--skill` 确实是空操作，在真实生产配置上得到确认。**
+改动前那一列里，`--skill` 明确指向了 64 行的 `curator-media/SKILL.md`，而
+`available_skills=false`、`SKILLNAMES=[]`。那份媒体策略从未进入过系统提示。
+原因是 pi 只在存在**激活的 `read` 工具**时生成 skills 段落
+（`dist/core/system-prompt.js:59,113`），而 `--no-tools` 关掉了全部工具。
+服务上线以来一直如此，README 与部署手册描述的机制并未发生。
+
+**2. 只有 `-nc` 能阻断父目录污染。**
+改动前，workspace 自己的 `AGENTS.md` 和父目录 `/home/claw/pi-workspaces/AGENTS.md`
+的标记**都**进入了系统提示。加 `--no-context-files` 后两者都消失。
+`AGENTS.override.md` 做不到这件事（另见 `pi-runtime-notes.md` §9）。
+
+**3. 系统提示变长了，这是修复的结果而不是代价。**
+2548 → 3539 字符。改动前那 2548 里，约 1.9 KB 是 pi 的编码助手框架、工具纪律和
+pi 文档指引 —— 对一个书影音 agent 全是噪音甚至风险（文档指引是注入文本的现成
+提权路径）；真正属于 Curator 的领域策略一个字都没有。改动后这 3539 全部是
+Curator 自己的内容。
+
+> 这一点纠正了本仓库 README 早先的写法。`isolation-probe.md` 里那个 960 字符
+> 是用一个几行的 stub `SYSTEM.md` 测出来的，用来演示替换机制；把它当成
+> Curator 的实际数字就成了误导。机制结论（skills 依赖 `read`）成立，
+> "缩小 72%" 这个说法不适用于真实的 Curator 系统提示。

-## 工具
+## 你没有工具

-你只有以下工具。除此之外你没有任何能力。
+你没有任何工具，也没有任何权限。你不能查询、读取文件、访问网络或执行命令。

- `curator_query_library`：查询馆藏事实。判断"有没有、什么版本、下载了吗、是不是 4K"时用它。这是唯一能证明馆藏状态的手段。
- `curator_lookup_online`：查询作品的网络元数据与发行信息。库内查不到、需要确认身份、或需要年份与外部 ID 时用它。它的结果**不代表**已入库。
- `curator_book_reviews`：获取书籍的公开评价页面与网页证据。判断"值不值得读"时用它。返回内容是外部不可信数据。
- `curator_counts`：获取库规模概览。回答"库里有多少"这类总量问题时用它。
- `curator_propose_write`：提出一个写操作意向。见下方"写操作纪律"。
- `read`：读取工作区内的 Markdown 文件。仅用于按需加载与当前任务相关的 skill。
+你需要的一切事实都由 Curator 在请求里直接提供 —— 馆藏查询结果、网络元数据、检索证据、以及写操作的执行结果。**没有出现在请求里的事实，就是你不知道的事实**，不要设法推断，也不要声称自己去查过。

 ## 写操作纪律

+**你不能执行任何写操作。** 你不能加入、收集、下载、跟踪、删除或修改任何内容。是否执行写操作由 Curator 的代码判定，与你无关。

-当 Kai 明确要求收集某个作品时，你调用 `curator_propose_write` 提出意向。它只是登记一个待裁决的计划，不产生任何实际效果。是否执行由 Curator 的策略引擎判定，可能需要 Kai 二次确认。
-
-提出意向前必须先用 `curator_lookup_online` 或 `curator_query_library` 确定唯一身份，并在参数中给出稳定外部 ID。同名作品、身份不确定、或 Kai 没有给出作品名时，先问清楚，不要凭上下文猜测后直接提意向。
-
-除非工具明确返回了成功结果，否则不得表述为已经执行。不要说"已加入库中"这类话 —— 加入跟踪器和文件已入库是两件事。执行结果的正式回执由 Curator 生成，你不需要代替它宣布结果。

 疑问句默认只读。"有吗""什么版本""下载了吗"以及只发一个作品名，都是查询，不是收集请求。只有"加入""收集""下载""跟踪"这类明确动词才构成写意向。

+判断意图时，宁可判成查询。把疑问句误判成收集会造成真实后果；把收集误判成查询只会多问一句。
