+
+## Problem
+
+The outer `run_code` tool persisted complete rendered content, but its editor presenter ignored that content and rebuilt the card body from a logs-only `presentationMeta` projection. A result-only run appeared correct because an empty presenter body let ACP and TUI fall back to `tool/result.content`. Once the program emitted a log, the presenter supplied non-empty content, that fallback stopped, and the returned value disappeared from the completed card. Failure text and a spill policy's final head/tail preview were vulnerable to the same split ownership.
+
+Nested Code calls never owned cards, so producing metadata for the outer call solely to reconstruct one incomplete card also obscured the intended one-card boundary.
+
+## Decision
+
+The `run_code` output renderer remains the single owner of model-facing outer content. It renders captured logs followed by the return value, the explicit no-output marker, or the failure content produced by the canonical tool pipeline. Post-execute policy and spill may replace that content before it is persisted.
+
+`run_code.presentResult` now forwards the final `result.content` into one generic result card. It deliberately omits the title so the pending card retains the program text. The existing logs metadata remains in `tool/result` for transcript compatibility, but the presenter no longer treats it as a second content source: `tool/result.content` is the durable, replayable, post-policy projection.
+
+Nested dispatch remains unchanged. Calls marked by `exec.parent` emit bounded `tool/code-dispatch` diagnostics but no `tool/call` or `tool/result` surface cards, so one outer `run_code` invocation still produces exactly one card.
+
+## Testing
+
+Presenter unit coverage pins logs-only, result-only, logs-plus-result, no-output, failure, and spilled-result content. Every case proves stale metadata cannot replace the final content.
+
+The keyless ACP and TUI Code Mode snapshots execute one outer program that performs two nested bash calls, logs `captured output`, and returns `CODE_ONE+CODE_TWO`. Both surfaces show one completed outer card containing both lines and no nested cards.
+
+## Alternatives considered
+
+**Append the return value to logs metadata.** Rejected because metadata would duplicate the renderer, need a second stable formatting contract for every JSON root, and still miss post-policy content replacement or spill previews.
+
+**Merge presenter metadata with `result.content`.** Rejected because the rendered content already contains the logs; merging would duplicate them and require brittle deduplication.
+
+**Create one card per nested dispatch.** Rejected because intermediate values are intentionally execution-local and never model-facing. Multiple cards would expose an implementation trace instead of the single Code Mode operation the model and user invoked.
+
+## Consequences
+
+ACP and TUI now display the same complete content the model receives and replay persists, including post-policy spill previews. The change adds or removes no event fields and requires no session-format bump. Existing and future replay records remain valid because the presenter ignores logs metadata when choosing card content and reads their durable rendered content.

+# Agent Note: 保证 Code Mode 结果卡片内容完整
+
+Status: implemented
+
+[English](2026-07-20-code-mode-result-card-completeness.md) | 中文
+
+## 问题
+
+外层 `run_code` 工具会持久化完整的渲染内容，但编辑器的卡片展示逻辑忽略了这些内容，转而根据仅含日志的 `presentationMeta` 投影重新构建卡片正文。仅有结果的运行看似正确，是因为展示逻辑未提供正文时，ACP 和 TUI 会回退到 `tool/result.content`。只要程序输出一条日志，展示逻辑就会提供非空内容，回退随即停止，返回值便会从完成态卡片中消失。失败文本以及输出落盘策略最终生成的头尾预览，也会受到同一职责拆分的影响。
+
+嵌套 Code 调用从不生成自己的卡片。因此，仅仅为了重建这一张不完整卡片而给外层调用生成元数据，还掩盖了每次外层调用只生成一张卡片的预期边界。
+
+## 决策
+
+`run_code` 输出渲染器继续作为面向模型的外层内容的唯一所有者。它先渲染已捕获的日志，然后渲染返回值、显式的无输出标记，或规范工具流水线生成的失败内容。Post-execute 策略与输出落盘机制可以在内容持久化之前替换它。
+
+`run_code.presentResult` 会把最终的 `result.content` 转交给一张通用结果卡片。它有意省略标题，使待完成卡片保留程序文本。现有日志元数据仍保留在 `tool/result` 中，以维持 transcript（文本记录）兼容性；但展示逻辑不再把它视为第二个内容来源：`tool/result.content` 才是持久、可回放且经过 post-policy 处理的投影。
+
+嵌套分发保持不变。带有 `exec.parent` 标记的调用会发出有界的 `tool/code-dispatch` 诊断，但不会生成与 `tool/call` 或 `tool/result` 对应的界面卡片，因此一次外层 `run_code` 调用仍然只会生成一张卡片。
+
+## 测试
+
+展示逻辑的单元测试覆盖仅有日志、仅有结果、日志与结果并存、无输出、失败和结果落盘六种情况。每个用例都证明，陈旧元数据无法替换最终内容。
+
+无密钥的 ACP 与 TUI Code Mode 快照会执行一个外层程序：程序进行两次嵌套 bash 调用，记录 `captured output`，并返回 `CODE_ONE+CODE_TWO`。两个界面都只显示一张完成态外层卡片，其中包含这两行内容，且没有嵌套卡片。
+
+## 备选方案
+
+**把返回值追加到日志元数据：**不予采纳。元数据会与渲染器重复，并且需要为每一种 JSON 根另行维护稳定的格式化契约；post-policy 内容替换或输出落盘预览仍然会被遗漏。
+
+**把展示元数据与 `result.content` 合并：**不予采纳。渲染内容已经包含日志；合并会造成重复，还需要依赖脆弱的去重逻辑。
+
+**为每次嵌套分发创建一张卡片：**不予采纳。中间值有意只存在于执行期间，永远不面向模型。多张卡片会暴露实现轨迹，而不是模型与用户调用的单次 Code Mode 操作。
+
+## 影响
+
+ACP 和 TUI 会显示模型接收、回放持久化的同一份完整内容，其中包括 post-policy 输出落盘预览。该变更不增加或删除任何事件字段，也不需要提升会话格式版本。现有及未来的回放记录都保持有效，因为展示逻辑在选择卡片内容时会忽略日志元数据，转而读取记录中的持久化渲染内容。

 **Concurrency is serialized.** Each run owns a dispatch queue, so even `Promise.all` executes tool calls in submission order. Settlement abandons queued calls that have not started. Parallelism requires per-tool concurrency-safety metadata.
