# Manually dispatch a Radicle issue-poll Buildkite build (same as the schedule).
#
# The 10m Buildkite schedule already sets RADICLE_TRIGGER=poll. Use this when you
# want an immediate poll without waiting for the next tick.
#
# Buildkite UI (no script needed):
#   https://buildkite.com/nandi/sleek-5u9xbr → New Build
#   Branch: main (or tip you want)
#   Environment variables: RADICLE_TRIGGER=poll
#   Create Build → runs radicle-issue-poll → poll-issues.sh
#
# CLI:
#   ./scripts/buildkite/dispatch-poll.sh
#   # loads BUILDKITE_API_TOKEN from OpenBao when OPENBAO_TOKEN is set:
#   #   eval "$(./scripts/configure-buildkite-from-openbao.sh)"
#   # or set BUILDKITE_API_TOKEN yourself.
#
# Specific issue (skip poll; run agent for one id):
#   ./scripts/buildkite/dispatch-poll.sh --issue <issue-id>
#   # same as: ./scripts/buildkite/trigger-issue-build.sh <issue-id>
#
# Optional env:
#   BUILDKITE_ORG=nandi
#   BUILDKITE_PIPELINE=sleek-5u9xbr
#   BUILDKITE_BRANCH=main
#   BUILDKITE_API_URL=https://api.buildkite.com/v2
