Compares caller-estimated tokens (and optionally turn count) against a hardcoded threshold and recommends whether to checkpoint. Purely advisory — no server-side token accounting, no persisted state. A `should_checkpoint: true` response also fire-and-forget enqueues a scoped dream pass (T501).

## Path parameters

- `id` integer, required

## Request body

- object
  - `estimated_tokens` integer, required
  - `turn_count` integer

## Response `200`

Checkpoint recommendation.

- object
  - `should_checkpoint` boolean
  - `reason` string
  - `threshold` integer

## Other responses

- `400`: Request body/query failed Zod validation.
- `401`: Missing or invalid credentials.
