Huanqi Cao 6fb226ea24 feat(loader): interpolate the entry disabled field
The Windows platform layer disables tool-bash and inserts the pwsh stack, but the shipped presets each mount a tool-bash row that re-enabled the tool on win32 — the session had both a PowerShell-backed bash tool and tool-pwsh, silently, because no spec pinned the composed preset layer.

The Loader now evaluates a disabled: !!js expression against the loader context at every mount decision; disabled is the only interpolated metadata field, and the raw node stays in the options so write-back keeps the !!js form. The standard/code/cordis presets gate tool-bash with process.platform === 'win32', verify-cordis-config allows expressions in disabled only, and the windows-shell spec pins the preset-level invariant.

# Agent Note:Loader 插值条目 `disabled` 字段
Status: implemented
[English](2026-08-11-loader-entry-disabled-interpolation.md) | 中文
## 问题
Windows 平台层(`packages/bundle/base/windows.cordis.patch.yml`)在 win32 上禁用 `tool-bash`,但 shipped 预设各自挂载了一行 `tool-bash`。预设行最后组合,同名行在 Windows 上重新启用了该工具——会话同时拥有 `tool-bash`(PowerShell 后端)与 `tool-pwsh`,且是静默的,因为没有 spec pin 组合后的预设层。条目元数据没有条件机制:`!!js` 只在插件 `config` 下插值,[postmortem 0002](../../../../docs/postmortem/0002-js-expression-disabled-filesystem-tools.md) 记录了 `disabled: !!js ...` 保持真值表达式对象、在所有平台上禁用该行的事故。
## 决策
Loader 插值条目 `disabled` 字段(`vendor/loader/src/config/entry.ts`):`!!js` 表达式在每次挂载决策时基于 loader 上下文求值。`disabled` 是唯一被插值的元数据字段;`id`、`name`、`group`、`inject` 保持静态。原始节点保留在 options 中,写回保持 `!!js` 形式。shipped 预设(standard、code、cordis)用 `disabled: !!js process.platform === 'win32'` 门控 `tool-bash`,`verify-cordis-config` 现在只允许 `disabled` 中的表达式。
## 备选方案
**行上的声明式 `platform` 字段。** 静态且可被门禁检查,但它是 `!!js` 之外的第二种组合机制,且平台只是今天的条件。
**预设级平台 overlay。** 被否:条件应当属于它所治理的行。
## 后果
行可以按平台或环境门控自身;错误的表达式在启动时响亮失败。其余元数据字段保持字面值,门禁继续拒绝那里的表达式——`disabled` 上的 postmortem-0002 隐患以「求值」而非「禁止」关闭。`minimal` 预设缺失的 win32 PTY 栈是预设元数据的后续工作。
