canonical schema 字段语义与各 provider 原始格式要点（gmail/outlook/google-calendar）。产出格式映射时使用。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# canonical schema 字段语义
## 邮件（recordKind = "mail"）
- `providerMessageId`（必填）：provider 内全局唯一消息 id（Gmail `id`；Outlook `id`）。
- `providerThreadId`：会话 id（Gmail `threadId`；Outlook `conversationId`）。
- `subject` / `snippet`：主题；正文摘要（Gmail `snippet`；Outlook `bodyPreview`）。
- `textBody` / `htmlBody`：正文明文与 HTML；两者都有时都输出。
- `receivedAt` / `sentAt`：ISO-8601。
- `isRead` / `isStarred` / `isDraft`：布尔。
- `addresses`：`{role, address, displayName?}` 数组；role 枚举 from/sender/to/cc/bcc/reply-to。
- `memberships`：Gmail labelIds 原样（不含语义推导）。
- `attachments`：`{providerId?, filename?, mimeType?, size?, inline?}`。
## 日程（recordKind = "calendar"）
- `providerEventId`（必填）、`title`（必填，缺失时输出 `"(无标题)"`）、
`startsAt` / `endsAt`（必填，ISO-8601）。
- `allDay`：全天事件（Google `start.date` 无 dateTime 时为 true）。
- `timeZone` / `location` / `description` / `status` / `providerRevision`（etag）。
- `organizer` / `attendees`：`{role, address, displayName?}`；日程专用 role：
organizer 用 `"organizer"`、参与人用 `"attendee"`。
- 墓碑：Google `status === "cancelled"` → isTombstone。
# provider 原始格式要点
## gmail（映射输入 = Gmail REST 资源形状）
- `payload.headers`：`{name, value}` 数组，name 大小写不敏感 → 地址字段。

How to install
mdr add nxcoreai/everroom/canonical-schema@sha256:d9b8737c9b755c4cThe line at the top of this page pins the label git:20260905.48ce71f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
