# Hours Substrate

`GET /api/hours/substrate`

## Request

- Base URL: `https://data.humanarchive.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://data.humanarchive.ai/api/hours/substrate`
- Auth: none declared

The corpus's hours as the substrate's derived layer publishes them — the corpus document
the Dashboard reads its unlinked share and its unknown-cuts gate from.

A GET under the authenticated router; no admin group, because it writes nothing. The ledger
door being unreachable is a 503 (`_guard`); a BLIND document is a 200 whose `total` is None
and whose `blind` says why — never a total of zero.

## Response `200`

Successful Response

- unknown
