Merge pull request 'ci(sop-tier-check): AND-composition of required team approvals per tier' (#225) from ci/sop-tier-check-and-composition into main

internal#189: replaces the OR-gate ("≥1 approver from eligible teams")
with an AND-gate ("all required clauses must each have ≥1 approver").

New TIER_EXPR map (single source of truth at top of script):
  tier:low    → engineers,managers,ceo (OR, same as before)
  tier:medium → managers AND engineers AND qa???,security??? (AND)
  tier:high   → ceo (single-team, framework wired for future AND)

"???" suffix: teams not yet created in Gitea (qa, security). The
expression always fails for these until the teams are created and the
markers are removed. The clear error message guides ops to create them.

Expression syntax documented at top of script. Clause-level pass/fail is
annotated in the notice/error lines so PR authors can see exactly which
gate is missing without SOP_DEBUG=1.

BURN-IN (internal#189 Phase 1): continue-on-error: true on the job
prevents AND-composition from blocking PRs during the 7-day window.
Remove after 2026-05-17 per the workflow BURN-IN NOTE comment.

SOP_LEGACY_CHECK=1 env var: forces OR-gate for individual runs,
enabling a grace window for PRs in-flight at deploy time.

+#   - Dropped `environment: pypi-publish` — Gitea Actions does not support
+#     named environments or OIDC trusted publishers
+#   - Replaced `pypa/gh-action-pypi-publish@release/v1` (OIDC) with
+#     `twine upload` using PYPI_TOKEN secret — same mechanism as a local
+#     `python -m twine upload` with a PyPI token
+#   - Replaced `github.ref_name` (GitHub-only) with `${GITHUB_REF#refs/tags/}`
+#     — Gitea Actions exposes github.ref (the full ref) but not ref_name
+#   - Dropped `merge_group` trigger (Gitea has no merge queue)
+#   - Dropped `staging` branch trigger (no staging branch exists in this repo)
+#
+# PyPI publishing: requires PYPI_TOKEN repository secret (or org-level secret).
+# Set via: repo Settings → Actions → Variables and Secrets → New Secret.
+# The token should be a PyPI API token scoped to molecule-ai-workspace-runtime.
+#
+# The DISPATCH_TOKEN cascade (git push to template repos) is unchanged —
+# it uses the Gitea API directly and was already Gitea-compatible.

-name: Auto-promote :latest after main image build
-
-# Retags `ghcr.io/molecule-ai/{platform,platform-tenant}:staging-<sha>`
-# → `:latest` after either the image build or E2E completes on a `main`
-# push, gated on E2E Staging SaaS not being red for that SHA.
-#
-# Why two triggers:
-#
-#   `publish-workspace-server-image` and `e2e-staging-saas` are both
-#   paths-filtered, but with DIFFERENT path sets:
-#
-#     publish-workspace-server-image:
-#       workspace-server/**, canvas/**, manifest.json
-#
-#     e2e-staging-saas (full lifecycle):
-#       workspace-server/internal/handlers/{registry,workspace_provision,
-#       a2a_proxy}.go, workspace-server/internal/middleware/**,
-#       workspace-server/internal/provisioner/**, tests/e2e/test_staging_full_saas.sh
-#
-#   The E2E set is a strict SUBSET of the publish set. So:
-#     - canvas/** changes → publish fires, E2E does not
-#     - workspace-server/cmd/** changes → publish fires, E2E does not
-#     - workspace-server/internal/sweep/** → publish fires, E2E does not
-#
-#   The previous version triggered ONLY on E2E completion, which meant
-#   non-E2E-path changes (canvas, cmd, sweep, etc.) rebuilt the image
-#   but never advanced `:latest`. Result: as of 2026-04-28 this workflow
-#   had run zero times since merge despite eight main pushes — `:latest`
-#   was ~7 hours / 9 PRs behind main with no human realising. See
-#   `molecule-core` Slack discussion 2026-04-28.
-#
-#   Adding `publish-workspace-server-image` as a second trigger closes
-#   the gap: any image rebuild on main eligibly advances `:latest`.
-#
-# Why E2E remains a kill-switch (not the trigger):
-#
-#   When E2E DID run for this SHA and ended red, we abort — `:latest`
-#   stays on the prior known-good digest. When E2E didn't run (paths
-#   filtered out), we proceed: pre-merge gates already validated this
-#   SHA on staging via auto-promote-staging requiring CI + E2E Canvas +
-#   E2E API + CodeQL all green. Image content for non-E2E-paths
-#   (canvas, cmd, sweep) is exercised by those staging gates.
-#
-# Why `main` only:
-#
-#   `:latest` is what prod tenants pull. We only want SHAs that have
-#   reached main (via auto-promote-staging) to advance `:latest`.
-#   Triggering on staging would let a staging-only revert advance
-#   `:latest` to a SHA that never reaches main, breaking the "production
-#   runs what's on main" invariant.
-#
-# Idempotency:
-#
-#   When a SHA touches paths that match BOTH publish and E2E, both
-#   workflows fire and complete. Both trigger this workflow on
-#   completion → two runs race. Both retag `:staging-<sha>` →
-#   `:latest`. crane tag is idempotent (re-tagging the same digest is a
-#   no-op), so the second run is harmless. concurrency group serializes
-#   them anyway.

-name: Auto-promote staging → main
-
-# Fires after any of the staging-branch quality gates complete. When ALL
-# required gates are green on the same staging SHA, opens (or re-uses)
-# a PR `staging → main` and enables auto-merge so the merge queue lands
-# it. Closes the gap that historically let features sit on staging for
-# weeks waiting for a bulk promotion PR (see molecule-core#1496 for the
-# 1172-commit example).
-#
-# 2026-04-28 rewrite (PR #142): the previous version did a direct
-# `git merge --ff-only origin staging && git push origin main`. That
-# breaks against main's branch-protection ruleset, which requires
-# status checks "set by the expected GitHub apps" — direct pushes
-# can't satisfy that condition (only PR merges through the queue can).
-# The workflow was failing every tick with:
-#   remote: error: GH006: Protected branch update failed for refs/heads/main.
-#   remote: - Required status checks ... were not set by the expected GitHub apps.
-# Fix: mirror the PR-based pattern from auto-sync-main-to-staging.yml
-# (the reverse-direction sync, fixed in #2234 for the same reason).
-# Both directions now use the same merge-queue path that humans use,
-# no special-case bypass.
-#
-# Safety model:
-# - Runs ONLY on workflow_run events for the staging branch.
-# - Requires EVERY named gate workflow to have the same head_sha and
-#   all be `conclusion == success`. If any of them is red, skipped,
-#   cancelled, or pending, we abort (stay on the current main).
-# - The PR base=main head=staging path lets GitHub itself enforce
-#   branch protection. If main has diverged from staging or required
-#   checks aren't satisfied, the merge queue declines the PR — no
-#   need for a manual ff-only ancestry check here.
-# - Loop safety: the auto-sync-main-to-staging workflow fires when
-#   main lands the auto-promote PR, but its merge into staging is by
-#   GITHUB_TOKEN which doesn't trigger downstream workflow_run events
-#   (GitHub Actions safety). So this workflow doesn't re-fire from
-#   its own promote landing.
-#
-# Toggle via repo variable AUTO_PROMOTE_ENABLED (true/unset). When
-# unset, the workflow logs what it would have done but doesn't open
-# the PR — useful for dry-running the gate logic without surfacing
-# a noisy PR while staging CI is still flaky.
-#
-# **One-time repo setting (load-bearing):** this workflow opens the
-# staging→main PR via `gh pr create` using the default GITHUB_TOKEN.
-# Since GitHub's 2022 default change, that token cannot create or
-# approve PRs unless the repo opts in. The toggle is at:
-#
-#   Settings → Actions → General → Workflow permissions
-#   → ✅ Allow GitHub Actions to create and approve pull requests
-#
-# Without it, every workflow_run fails with:
-#
-#   pull request create failed: GraphQL: GitHub Actions is not
-#   permitted to create or approve pull requests (createPullRequest)
-#
-# Observed 2026-04-29 01:43 UTC blocking promotion of fcd87b9 (PRs
-# #2248 + #2249); manually bridged via PR #2252. Re-check this
-# setting if auto-promote starts failing with createPullRequest
-# errors after a repo or org admin change.

-      # observed 2026-05-03). Sequence: auto-promote merges via the staging
-      # merge-queue's MERGE strategy, creating a merge commit on main that
-      # staging doesn't have. auto-sync then merges main back into staging
-      # via another merge commit (the queue's MERGE strategy applies on
-      # the staging side too, even when the workflow's local FF would
-      # have sufficed). Now staging has a new merge-commit SHA whose
-      # tree == main's tree — but auto-promote sees "staging ahead of
-      # main by 1" and opens YET another empty promote PR. Each round
-      # costs ~30-40 min wallclock, ~2 manual approvals, and burns a
-      # full CodeQL Go run (~15 min). Without this guard the cycle
-      # repeats indefinitely.
-      #
-      # Long-term fix is to switch the merge_queue ruleset's
-      # `merge_method` away from MERGE so FF-able PRs land cleanly,
-      # but that's a broader change affecting every staging PR's
-      # commit shape. This guard is the one-line surgical fix that
-      # breaks the cycle without touching merge-queue config.
-      #
-      # Fail-open: if `git diff` errors for any reason, fall through
-      # to the gate check (preserve existing behavior). Only skip

-name: Auto-sync main → staging
-
-# Reflects every push to `main` back onto `staging` so the
-# staging-as-superset-of-main invariant holds.
-#
-# Background:
-#
-# `auto-promote-staging.yml` advances main via `git merge --ff-only`
-# + `git push origin main` — that's a clean fast-forward, no merge
-# commit. But manual merges of `staging → main` PRs through the
-# GitHub UI / API create a merge commit on main that staging
-# doesn't have. The next `staging → main` PR then evaluates as
-# "BEHIND" because staging is missing that merge commit, requiring
-# a manual `gh pr update-branch` round-trip.
-#
-# This happened twice on 2026-04-28 (PRs #2202, #2205, both manual
-# bridges). Each time the bridge needed update-branch + a re-CI
-# round before merging. Operationally annoying and avoidable.
-#
-# Architecture:
-#
-# This repo's `staging` branch is protected by a `merge_queue`
-# ruleset (id 15500102) that blocks ALL direct pushes — no bypass
-# even for org admins or the GitHub Actions integration. Direct
-# `git push origin staging` returns GH013. So instead of pushing
-# directly, this workflow:
-#
-#   1. Checks if main is already in staging's ancestry → no-op.
-#   2. Creates an `auto-sync/main-<sha>` branch from staging.
-#   3. Tries `git merge --ff-only origin/main` → if staging hasn't
-#      diverged this is a clean ff.
-#   4. Otherwise `git merge --no-ff origin/main` to absorb main's
-#      tip while keeping staging's history.
-#   5. Pushes the auto-sync branch.
-#   6. Opens a PR (base=staging, head=auto-sync/main-<sha>) and
-#      enables auto-merge so the merge queue lands it.
-#
-# This mirrors the path human PRs take through staging — same
-# rules, same gates, no special-case bypass.
-#
-# Loop safety:
-#
-# `GITHUB_TOKEN`-authored merges (including the merge queue's land
-# of the auto-sync PR) do NOT trigger downstream workflow runs
-# (GitHub Actions safety). So when the auto-sync PR lands on
-# staging, `auto-promote-staging.yml` is NOT triggered by that
-# push. The next developer push to staging triggers auto-promote
-# normally. No loop possible.
-#
-# Concurrency:
-#
-# Two pushes to main in quick succession (e.g., manual UI merge
-# immediately followed by auto-promote-staging's ff-merge) could
-# otherwise open two overlapping auto-sync PRs. The concurrency
-# group serializes runs; the second waits for the first to exit.
-# (The first run exits after opening + auto-merge-queueing the PR,
-# not after the merge actually completes — so multiple PRs can be
-# open simultaneously, but the merge queue handles them serially.)
-
-on:
-  push:
-    branches: [main]
-  # workflow_dispatch lets:
-  #   1. Operators manually backfill a missed sync (e.g. after a manual
-  #      UI merge that the runner missed).
-  #   2. auto-promote-staging.yml's polling tail explicitly invoke us
-  #      after the promote PR lands. This is load-bearing: when the
-  #      merge queue lands a promote-PR merge, the resulting push to
-  #      `main` is "by GITHUB_TOKEN", and per GitHub's no-recursion
-  #      rule (https://docs.github.com/en/actions/using-workflows/triggering-a-workflow#triggering-a-workflow-from-a-workflow)
-  #      that push event does NOT fire any downstream workflows. The
-  #      `on: push` trigger above is silently dead for the very pattern
-  #      we exist to handle. Verified empirically 2026-05-02 against
-  #      SHA 76c604fb (PR #2437 staging→main): only ONE workflow fired
-  #      (publish-workspace-server-image, dispatched explicitly by
-  #      auto-promote's polling tail with an App token). Every other
-  #      `on: push: branches: [main]` workflow — including this one —
-  #      was suppressed. Until the underlying merge call moves to an
-  #      App token, an explicit dispatch is the only reliable path.

+# Registry note (2026-05-10): This workflow previously used GHCR
+# (ghcr.io/molecule-ai/platform-tenant) — that registry was retired
+# during the 2026-05-06 Gitea suspension migration when publish-
+# workspace-server-image.yml switched to the operator's ECR org
+# (153263036946.dkr.ecr.us-east-2.amazonaws.com/molecule-ai/
+# platform-tenant). The GHCR → ECR migration was never applied to
+# this file, so canary-verify was silently smoke-testing the stale
+# GHCR image while the actual staging/prod tenants ran the ECR image.
+# Result: smoke tests could not catch a broken ECR build. Fix:
+#   - Wait step: reads SHA from running canary /health (tenant-
+#     agnostic, works regardless of registry).
+#   - Promote step: calls CP redeploy-fleet endpoint with target_tag=
+#     staging-<sha>, same mechanism as redeploy-tenants-on-main.yml.
+#     No longer attempts GHCR crane ops.

 # Dependencies:
 #   - publish-workspace-server-image.yml publishes :staging-<sha>
-#     (NOT :latest) on main merge
-#   - canary tenants are configured to pull :staging-<sha> as their

-#     canary provisioner code path OR rotate via an admin endpoint)
+#     to ECR on staging and main merges.
+#   - Canary tenants are configured to pull :staging-<sha> from ECR

 name: CodeQL
 
-# Controls CodeQL scan triggers for this repo.
+# Stub workflow — CodeQL Action is structurally incompatible with Gitea
+# Actions (post-2026-05-06 SCM migration off GitHub).
 #
-# GitHub's "Code quality" default setup (the UI-configured one) is
-# hardcoded to only scan the default branch — on this repo that's
-# `staging`, so PRs promoting staging→main would otherwise never be
-# scanned. This workflow fills that gap by explicitly scanning both
-# branches on push and PR.
+# Why this is a stub, not a real CodeQL run:
 #
-# Runs on ubuntu-latest (GHA-hosted — public repo, free). GHAS is NOT
-# enabled on this repo, so results are not uploaded to the Security
-# tab — the scan fails the PR check on findings, and the SARIF is
-# kept as a workflow artifact for triage.
+# 1. github/codeql-action/init@v4 hits api.github.com endpoints
+#    (CodeQL CLI bundle download + query-pack registry + telemetry)
+#    that Gitea 1.22.x does NOT proxy. The act_runner has
+#    GITHUB_SERVER_URL=https://git.moleculesai.app correctly set
+#    (per saved memory feedback_act_runner_github_server_url and
+#    /config.yaml on the operator host), but the Gitea API surface
+#    simply does not implement the codeql-action bundle endpoints.
+#    Observed in run 1d/3101 (2026-05-07): "::error::404 page not
+#    found" inside the Initialize CodeQL step, before any analysis.
+#
+# 2. PR #35 attempted to mark `continue-on-error: true` at the JOB
+#    level (correct YAML structure). Gitea 1.22.6 does NOT propagate
+#    job-level continue-on-error to the commit-status API — every
+#    matrix leg still posts `failure` to the status surface, which
+#    keeps OVERALL=failure on every push to main + staging and
+#    blocks visual auto-promote signals (#156).
+#
+# 3. Hongming policy decision (2026-05-07, task #156): CodeQL is
+#    ADVISORY, not blocking, on Gitea Actions. We do not block PR
+#    merge or staging→main promotion on CodeQL findings until we
+#    have a Gitea-compatible static-analysis pipeline.
+#
+# What this stub preserves:
+#
+# - Workflow name `CodeQL` (referenced by auto-promote-staging.yml
+#   line 67 as a workflow_run gate — must stay stable).
+# - Job name template `Analyze (${{ matrix.language }})` and the
+#   3-leg matrix (go, javascript-typescript, python). Branch
+#   protection / required-check parity (#144) keys on these
+#   exact context names.
+# - merge_group + push + pull_request + schedule triggers, so the
+#   merge-queue check name still resolves (per saved memory
+#   feedback_branch_protection_check_name_parity).
+#
+# Re-enabling real analysis (future work):
+#
+# - Option A: self-hosted Semgrep / OpenGrep via a custom action
+#   that doesn't hit api.github.com. Tracked behind #156 follow-up.
+# - Option B: Sonatype Nexus IQ or similar, called from a step
+#   that uses the Gitea-issued token only.
+# - Option C: re-host this workflow on a small GitHub mirror used
+#   ONLY for SAST (push-mirrored from Gitea). Acceptable trade-off
+#   if/when payment is restored on a non-suspended GitHub org —
+#   but per saved memory feedback_no_single_source_of_truth, we
+#   should design for multi-vendor backup, not GitHub-only SAST.
+#
+# Until one of those lands, this stub keeps commit-status green so
+# the auto-promote chain isn't permanently red on a tool we cannot
+# actually run.
+#
+# Security policy: ADVISORY. We accept the residual risk of un-scanned
+# pushes during this window. Compensating controls in place:
+#   - secret-scan.yml runs on every push (active, blocks on hits)
+#   - block-internal-paths.yml blocks forbidden file paths
+#   - lint-curl-status-capture.yml catches one specific class of bug
+#   - branch-protection-drift.yml + the merge_group required-checks
+#     parity keep the gate surface stable
+# These are not equivalent to CodeQL coverage. Status of the
+# replacement plan is tracked in #156.

+#     `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

+#     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):

+#      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

+# concurrent runs of this workflow both try to bind 0.0.0.0:5432 — the
+# second postgres FATALs with `could not create any TCP/IP sockets:
+# Address in use`, and Docker auto-removes it (act_runner sets
+# AutoRemove:true on service containers). By the time the migrations
+# step runs `psql`, the postgres container is gone, hence
+# `Connection refused` then `failed to remove container: No such

+# read its bridge IP via `docker inspect`. A host-net job container
+# can reach a bridge-net container directly via the bridge IP (verified
+# manually on operator host 2026-05-08).
+#
+# Trade-offs vs. the original `services:` shape:

+配套的私有仓库 [`molecule-controlplane`](https://git.moleculesai.app/molecule-ai/molecule-controlplane) 提供 SaaS 层 —— 多租户编排（EC2 + Neon + Cloudflare Tunnels）、KMS 信封加密、WorkOS 鉴权、Stripe 计费，以及 `tenant_resources` 审计表加 30 分钟 reconciler。
