The night shift for your codebase.

One mark, one warm colour, eight words. Everything here comes from a single night: hand off at 23:00, proof at 07:00.

The Jarvai app icon: a check folded from receipt paper, with the sun rising in the fold.

The mark

A check folded from one strip of receipt paper.

23:00going down 03:00 · the fold 07:00 · torn edge the 0 of exit 0
  1. It is folded from a receipt.Both strokes are one strip of thermal paper, folded once. The long stroke ends where the receipt was torn off. At Jarvai, done is printed, never just said.
  2. The sun is a zero.The circle rising in the fold is the 0 of exit 0, the Finish Line. It is also the sun coming up when you wake to proof.
  3. The angle is the night.The short stroke goes down at 23:00. The fold is 3 a.m. The long stroke climbs to 07:00, which is why it is longer: most of a night is spent climbing.

Vocabulary

One night, eight words.

Capitalise them as product names in the interface. In running text they read as ordinary words: hand off a task, raise a flag, print a receipt.

  1. Hand-off

    A task you give Jarvai before bed, with the command that decides when it's done.

  2. Night Shift

    Every hand-off running at once, each with its own agent and its own sandbox.

  3. Finish Line

    Your command, exit 0, on a clean checkout. Done means this and nothing else.

  4. Flag

    Raised when a claim has no evidence. Flagged work goes back to the agent.

  5. Race

    One task, several models. The tests pick the winner.

  6. Cap

    A hard limit on money, time and turns. Hit it and the run stops.

  7. Receipt

    Signed proof of a run: commit, commands, exit codes, checks, spend and model.

  8. Morning Brief

    Your phone at breakfast: what's verified, and what needs you.
