name: E2E API Smoke Test
# Extracted from ci.yml so workflow-level concurrency can protect this job
# from run-level cancellation (issue #458).
#
# Trigger model (changed 2026-04-28 — see auto-promote gap below):
#
# This workflow always FIRES on push/pull_request to staging+main, but
# only does real work when paths under `workspace-server/`,
# `tests/e2e/`, or this workflow file changed. The detect-changes job
# uses dorny/paths-filter to decide; the e2e-api job runs only if
# changes match. Otherwise the no-op job emits success so the workflow
# always produces a `completed/success` run record.
#
# Why: auto-promote-staging.yml's gate-check (line 99) treats "workflow
# didn't run" as failure, which dead-locked any platform-only or
# test-only push to staging that didn't touch workspace-server paths.
# Dropping the path filter on the trigger and gating real work
# internally guarantees the workflow always emits a result that the
# auto-promote chain can read. Same pattern applied to
# e2e-staging-canvas.yml in the same PR.

concurrency:
  # Per-SHA grouping (changed 2026-04-28 from per-ref). Per-ref had the
  # same auto-promote-staging brittleness as e2e-staging-canvas — back-
  # to-back staging pushes share refs/heads/staging, so the older push's
  # queued run gets cancelled when a newer push lands. Auto-promote-
  # staging then sees `completed/cancelled` for the older SHA and stays
  # put; the newer SHA's gates may eventually save the day, but if the
  # newer push gets cancelled too, we deadlock.
  #
  # See e2e-staging-canvas.yml's identical concurrency block for the full
  # rationale and the 2026-04-28 incident reference.
