# Mint a short-lived GitHub App installation token for the dispatch
# step below. We CANNOT use `secrets.GITHUB_TOKEN` to dispatch the
# downstream publish chain — workflow runs created by GITHUB_TOKEN
# do not fire `workflow_run` triggers on completion (the
# documented "no recursion" rule —
# https://docs.github.com/en/actions/using-workflows/triggering-a-workflow#triggering-a-workflow-from-a-workflow).
#
# Symptom this caused (root-caused on 2026-04-30): publish-image
# ran successfully twice (21313dc 14:41Z, 59dec57 15:21Z) but
# canary-verify and redeploy-tenants-on-main never chained,
# because the publish run's `triggering_actor` was
# `github-actions[bot]` (i.e. GITHUB_TOKEN). A manual dispatch
# earlier in the day with the operator's PAT (d850ec7 06:52Z) did
# chain — same workflow file, only the actor differed.
#
# An App token's triggering_actor is the App user (e.g.
# `molecule-ai[bot]`), which IS allowed to fire downstream
# workflow_run cascades.

# The App token minted above (before the promote-PR step) is
# also used by the polling tail below. Defense-in-depth: with
# the merge-queue-landed merge now using the App token, the
# main-branch push event SHOULD fire the publish/canary/redeploy
# cascade naturally — but if for any reason it doesn't (e.g. an
# unrelated event-suppression edge case), the explicit dispatches
# below still wake the chain.
- name: Wait for promote merge, then dispatch publish + redeploy (#2357)
# GITHUB_TOKEN-initiated merges suppress downstream `push` events
# (https://docs.github.com/en/actions/using-workflows/triggering-a-workflow#triggering-a-workflow-from-a-workflow).
# Result: when the merge queue lands the promote PR, the resulting
# main-branch push DOES NOT fire publish-workspace-server-image,
# so canary-verify and redeploy-tenants-on-main never run and
# tenants stay on stale code (issue #2357).
# Defense-in-depth dispatch. With the auto-merge call above
# now using the App token (this commit), the merge-queue-landed
# merge SHOULD fire publish-workspace-server-image naturally
# via on:push:[main] — App-token-initiated pushes DO trigger
# workflow_run cascades, unlike GITHUB_TOKEN-initiated ones
# (the documented "no recursion" rule —
# https://docs.github.com/en/actions/using-workflows/triggering-a-workflow#triggering-a-workflow-from-a-workflow).
#
# Workaround: poll for the merge to land, then explicitly
# `gh workflow run` publish-workspace-server-image. The dispatch
# MUST authenticate as the molecule-ai App (App token minted
# above) — not GITHUB_TOKEN — so that the resulting publish
# run's completion event can fire the workflow_run cascade
# into canary-verify + redeploy-tenants-on-main. See the prior
# step's comment for the GITHUB_TOKEN no-recursion details.
# This explicit dispatch stays as belt-and-suspenders for any
# edge case where the natural cascade misfires. If it never
# observably fires after this token swap (i.e. the publish
# workflow has already started by the time we get here), the
# second dispatch is a harmless no-op (publish-workspace-server-image
# has its own concurrency group that dedupes).
#
# Long-term fix: switch the auto-merge call above to use the
# same App token, so the merge's push event fires
# publish-workspace-server-image naturally and this polling tail
# becomes unnecessary. Tracked in #2357.
# See PR for #2357: pre-fix the merge action was via
# GITHUB_TOKEN, suppressing the cascade and forcing this tail
# to be the SOLE chain trigger. With the auto-merge token swap
# the tail becomes redundant in the happy path; keep until
# we've observed >=10 successful natural cascades, then drop.
