# Async (off-peak / "idle plan") bridge.

# that route through ZCode's off-peak ticket-queue backend — free compute when

# SSE keepalives during queue wait, forwards the LLM stream once a ticket is
# ready, and auto-retries on ticket-expired (up to maxRetries).
#
# IMPORTANT: off-peak needs the JWT captured by `auth login`. A credential
# without a JWT makes the route return 400 `async_credentials_unavailable`.
# Off-peak is a coding-plan feature: when `plan: start-plan`, the /async/*
# routes return 400 `async_plan_unsupported` even when enabled: true.

# Manual claim ("weekend plan") — mirrors the ZCode 3.10 desktop client's

# highest-priority one ({origin}/api/v1/zcode-plan/billing/claim) using the
# OAuth JWT + an Aliyun captcha token (same solver as start-plan). Weekend
# campaigns are quota-limited first-come-first-served; claimed plans activate
# at the campaign's `starts_at` and land as Start-Plan quota.
