# Repo Write Frontmatter

`PUT /v1/teams/{team_id}/repo/frontmatter`

## Request

- Base URL: `https://api.stormy.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://api.stormy.ai/v1/teams/{team_id}/repo/frontmatter`
- Auth: none declared

Set ONE flat frontmatter key on one file, as a real commit.

hash-object → temp-index write-tree → commit-tree → CAS update-ref, then
the same mirror hook receive-pack fires. A concurrent push loses no work:
the CAS fails and the editor retries against the new head.

## Path parameters

- `team_id` string, uuid, required

## Headers

- `authorization` string, nullable
- `x-darwin-token` string, nullable
