A sample that falls

A sample answers one question: how many delivered jobs does a person still need to check?

human: { sample: '10%' } has a person check one delivered job in ten. The job ships first; the check comes after, so a sampled job never waits. A check that finds a defect sends the job back with the note, and the AI redoes it at no charge to the buyer:

export default Service({
  name: 'Translation',
  input: { document: 'file', to: 'language: a BCP 47 tag, such as fr-CA' },
  output: { document: 'file' },
  human: { sample: '10%' },
  price: 49,
})

A fixed sample runs on Free. The person is you or your staff, in the owner console's review inbox.

Add floor, and the share falls while the checks find nothing:

human: { sample: '10%', floor: '1%', by: 'reviewer' },

$ npx services.dev check
services/translation.ts · 6 lines · $49 per job, within 48 hours, charged on delivery.
  who     A reviewer checks 10% of delivered jobs, falling to 1% while send-backs stay rare.
  plan    Launch (services.dev) · human: { sample, floor } at services/translation.ts:5

Each week, while send-backs on the sampled jobs stay under 2%, the share halves, never below floor. A week over 2% puts it back at sample. by names the role that checks: your staff, or a Pool's reviewers, each paid per check at the act and never clawed back. A falling sample runs on Launch.

The owner console counts how often the person at the line changed what the AI drafted, and what that cost:

open http://localhost:8787/console

lingua · 1 job · +$49.00 · AI $0.84 · you $48.16
Translation: a person approved 1 of 1 job unchanged. next: try human: 'risky', or delete the line.

When the person's changes stay under the bar the step's stakes set, the console proposes the next rung down, and moves the step back up on its own the week the evidence breaks: Move a step to AI. A step your rules reserve to a credential is the exception. That line is how the Service meets licensing by design, and check reads it from the rules, never from this count.
