# Mark a program as checked

`POST /v1/admin/programs/{company}/{program}/checked`

## Request

- Base URL: `http://api.technooptimist.io`
- URL: `http://api.technooptimist.io/v1/admin/programs/{company}/{program}/checked`
- Auth: HTTP bearer

Stamps the program's `checkedAt` ("last checked") without changing anything else: call it after re-verifying a program page when nothing changed. Body: `at` (ISO datetime or YYYY-MM-DD) defaults to now; `sources` (the pages checked) is required from routines. Program writes (patch, milestones, specs, full upsert) stamp it themselves.

## Path parameters

- `company` string, required
- `program` string, required

## Headers

- `x-routine-name` string: Name of the routine making the write; recorded as `routine:<name>` in the audit log.

## Request body

- object
  - `at` union
    - string, date-time
    - string
  - `sources` string[]

## Response `200`
