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 (revised 2026-04-29):
#
# Always FIRES on push/pull_request to staging+main. Real work is gated
# per-step on `needs.detect-changes.outputs.api` — when paths under
# `workspace-server/`, `tests/e2e/`, or this workflow file haven't
# changed, the no-op step alone runs and emits SUCCESS for the
# `E2E API Smoke Test` check, satisfying branch protection without
# spending CI cycles. See the in-job comment on the `e2e-api` job for
# why this is one job (not two-jobs-sharing-name) and the 2026-04-29
# PR #2264 incident that drove the consolidation.
#
# Parallel-safety (Class B Hongming-owned CICD red sweep, 2026-05-08)
# -------------------------------------------------------------------
# Same substrate hazard as PR #98 (handlers-postgres-integration). Our
# Gitea act_runner runs with `container.network: host` (operator host
# `/opt/molecule/runners/config.yaml`), which means:
#
#   * Two concurrent runs both try to bind their `-p 15432:5432` /
#     `-p 16379:6379` host ports — the second postgres/redis FATALs
#     with `Address in use` and `docker run` returns exit 125 with
#     `Conflict. The container name "/molecule-ci-postgres" is already
#     in use by container ...`. Verified in run a7/2727 on 2026-05-07.
#   * The fixed container names `molecule-ci-postgres` / `-redis` (the
#     pre-fix shape) collide on name AS WELL AS port. The cleanup-with-
#     `docker rm -f` at the start of the second job KILLS the first
#     job's still-running postgres/redis.
#
# Fix shape (mirrors PR #98's bridge-net pattern, adapted because
# platform-server is a Go binary on the host, not a containerised
# step):
#
#   1. Unique container names per run:
#         pg-e2e-api-${RUN_ID}-${RUN_ATTEMPT}
#         redis-e2e-api-${RUN_ID}-${RUN_ATTEMPT}
#      `${RUN_ID}-${RUN_ATTEMPT}` is unique even across reruns of the
#      same run_id.
#   2. Ephemeral host port per run (`-p 0:5432`), then read the actual
#      bound port via `docker port` and export DATABASE_URL/REDIS_URL
#      pointing at it. No fixed host-port → no port collision.
#   3. `127.0.0.1` (NOT `localhost`) in URLs — IPv6 first-resolve was
#      the original flake fixed in #92 and the script's still IPv6-
#      enabled.
#   4. `if: always()` cleanup so containers don't leak when test steps
#      fail.
#
# Issue #94 items #2 + #3 (also fixed here):
#   * Pre-pull `alpine:latest` so the platform-server's provisioner
#     (`internal/handlers/container_files.go`) can stand up its
#     ephemeral token-write helper without a daemon.io round-trip.
#   * Create `molecule-monorepo-net` bridge network if missing so the
#     provisioner's container.HostConfig {NetworkMode: ...} attach
#     succeeds.
# Item #1 (timeouts) — evidence on recent runs (77/3191, ae/4270, 0e/
# 2318) shows Postgres ready in 3s, Redis in 1s, Platform in 1s when
# they DO come up. Timeouts are not the bottleneck; not bumped.
#
# Item explicitly NOT fixed here: failing test `Status back online`
# fails because the platform's langgraph workspace template image
# (ghcr.io/molecule-ai/workspace-template-langgraph:latest) returns
# 403 Forbidden post-2026-05-06 GitHub org suspension. That is a
# template-registry resolution issue (ADR-002 / local-build mode) and
# belongs in a separate change that touches workspace-server, not
# this workflow file.

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.

  # ONE job (no job-level `if:`) that always runs and reports under the

  # on `needs.detect-changes.outputs.api`. Reason: GitHub registers a
  # check run for every job that matches `name:`, and a job-level
  # `if: false` produces a SKIPPED check run. Branch protection treats
  # all check runs with a matching context name on the latest commit as a
  # SET — any SKIPPED in the set fails the required-check eval, even with
  # SUCCESS siblings. Verified 2026-04-29 on PR #2264 (staging→main):
  # 4 check runs (2 SKIPPED + 2 SUCCESS) at the head SHA blocked
  # promotion despite all real work succeeding. Collapsing to a single
  # always-running job with conditional steps emits exactly one SUCCESS
  # check run regardless of paths filter — branch-protection-clean.
