Supply-chain hardening for the CI pipeline. 23 workflow files
modified, 59 mutable-tag refs replaced with commit SHAs.
The risk
Every `uses:` reference in .github/workflows/*.yml was pinned to a
mutable tag (e.g., `actions/checkout@v4`). A maintainer of an
action — or a compromised maintainer account — can repoint that
tag to malicious code, and our pipelines silently pull it on the
next run. The tj-actions/changed-files compromise of March 2025 is
the canonical example: maintainer credential leak, attacker
repointed several `@v<N>` tags to a payload that exfiltrated
repository secrets. Repos that pinned to SHAs were unaffected.
The fix
Replace each `@v<N>` with `@<commit-sha> # v<N>`. The trailing
comment preserves human readability ("ah, this is v4"); the SHA
makes the reference immutable.
Actions covered (10 distinct):
actions/{checkout,setup-go,setup-python,setup-node,upload-artifact,github-script}
docker/{login-action,setup-buildx-action,build-push-action}
github/codeql-action/{init,autobuild,analyze}
dorny/paths-filter
imjasonh/setup-crane
pnpm/action-setup (already pinned in molecule-app, listed here for completeness)
Excluded:
Molecule-AI/molecule-ci/.github/workflows/disable-auto-merge-on-push.yml@main
— internal org reusable workflow; we control its repo, threat model
is different from third-party actions. Conventional to pin to @main
rather than SHA for internal reusables.
The maintenance cost
SHA pinning means upstream fixes require manual SHA bumps. Without
automation, pinned SHAs go stale. So this PR also enables Dependabot
across four ecosystems:
- github-actions (workflows)
- gomod (workspace-server)
- npm (canvas)
- pip (workspace runtime requirements)
Weekly cadence — the supply-chain attack window is "minutes between
repoint and pull"; weekly auto-bumps don't help with zero-days
regardless. The point is to pull in non-zero-day fixes without
operator effort.
Aligns with user-stated principle: "long-term, robust, fully-
automated, eliminate human error."

The auto-promote-staging.yml gate-check (line 99) treats "workflow
didn't run" as failure. Path-filtered triggers on E2E API Smoke Test
and E2E Staging Canvas meant a platform-only or test-only push to
staging — say, the prior PR #2201 which only touched
tests/e2e/test_staging_full_saas.sh — never triggered the canvas
workflow, and auto-promote saw `missing/none`, marked all_green=false,
and aborted. Same class for any push that doesn't touch the gate's
watched paths. Dead-lock by design, never noticed because the gate
was new.
Fix per Design B (always-run + fast-skip):
- Drop `paths:` from the push/pull_request triggers on both gate
workflows. The workflow now always fires on every staging+main
push/PR.
- Add a `detect-changes` job using `dorny/paths-filter@v3` that
decides whether to do real work, scoped to the same paths the
trigger filter used to watch.
- Real work job (e2e-api / playwright) gates on
`needs: detect-changes; if: needs.detect-changes.outputs.X == 'true'`.
- Add a sibling `no-op` job that runs when the filter output is
false, emitting `::notice::… no-op pass`. The workflow run's
conclusion is `success` either way — auto-promote sees green and
proceeds.
manual `workflow_dispatch` and the weekly canvas `schedule` short-
circuit detect-changes to always-run — those triggers exist precisely
to exercise the suite and shouldn't be silently no-op'd.
Why this approach over making auto-promote-staging smarter:
The alternative (Design A, considered + rejected) was to teach
auto-promote-staging to read each gate's `paths:` filter and treat
"no run because filter excluded the commit" as conditional pass.
That couples auto-promote to other workflows' YAML schema and breaks
silently if a gate is renamed or its filter changes. Design B keeps
the auto-promote contract simple ("each gate emits success") and
makes each gate self-describing — adding a new gate doesn't require
touching auto-promote.
Cost: ~10-30s of runner overhead per gate per push for the no-op when
paths don't match. Negligible vs the alternative of dead-locked
auto-promote chains.

Self-contained happy-path E2E for the two runtimes the project commits
to first-class support for (task #116, completes the loop on the
"both must work end-to-end with tests" requirement).
What it proves per runtime:
1. POST /workspaces succeeds with the runtime + secrets
2. Workspace reaches status=online within its cold-boot window
(claude-code: 240s, hermes: 900s on cold apt + uv + sidecar)
3. POST /a2a (message/send "Reply with PONG") returns a non-error,
non-empty reply
4. activity_logs row written with method=message/send and ok|error
status (a2a_proxy.LogActivity contract)
Skip semantics: each phase independently checks for its required env
key (CLAUDE_CODE_OAUTH_TOKEN / E2E_OPENAI_API_KEY) and skips cleanly
if absent. The script always exit-0s if every phase either passed or
skipped — so wiring it into a no-keys CI job validates the script
itself stays clean without false-failing.
Idempotent: pre-sweeps any prior "Priority E2E (claude-code)" /
"Priority E2E (hermes)" workspaces so a run interrupted by SIGPIPE /
kill -9 (which bypasses the EXIT trap) doesn't poison the next run.
Same defensive pattern as test_notify_attachments_e2e.sh.
CI wiring:
- e2e-api.yml — runs on every PR with no LLM keys, both phases skip,
catches script-level regressions (set -u bugs, syntax issues, etc.)
- canary-staging.yml + e2e-staging-saas.yml already have the keys
via secrets.MOLECULE_STAGING_OPENAI_KEY and exercise wire-real
behavior — could be wired to opt-in if you want claude-code coverage
there too.
Local runs (from this branch, no keys):
=== Results: 0 passed, 0 failed, 2 skipped ===
Validates the capability primitives shipped in PRs #2137-2144: once
template PRs #12 (claude-code) + #25 (hermes) merge with their
declared provides_native_session=True + idle_timeout_override=900,
a manual run with both keys validates the full native+pluggable chain.

User asked to "keep optimizing and comprehensive e2e testings to prove all
works as expected" for the communication path. Adds three layers of coverage
for PR #2130 (agent → user file attachments via send_message_to_user) since
that path has the most user-visible blast radius:
1. Shell E2E (tests/e2e/test_notify_attachments_e2e.sh) — pure platform test,
no workspace container needed. 14 assertions covering: notify text-only
round-trip, notify-with-attachments persists parts[].kind=file in the
shape extractFilesFromTask reads, per-element validation rejects empty
uri/name (regression for the missing gin `dive` bug), and a real
/chat/uploads → /notify URI round-trip when a container is up.
2. Canvas AGENT_MESSAGE handler tests (canvas-events.test.ts +5) — pin the
WebSocket-side filtering that drops malformed attachments, allows
attachments-only bubbles, ignores non-array payloads, and no-ops on
pure-empty events.
3. Persisted response_body shape test (message-parser.test.ts +1) — pins
the {result, parts} contract the chat history loader hydrates on
reload, so refreshing after an agent attachment restores both caption
and download chips.
Also wires the new shell E2E into e2e-api.yml so the contract regresses
in CI rather than only in manual runs.

Adds branches: [main, staging] to e2e-api.yml triggers so the
auto-promote workflow can see E2E API status on staging SHA.
Without this, the promoter gate for E2E API always reports missing
and auto-promotion is permanently blocked.
molecule-core is a public repo — GHA-hosted minutes are free. The
self-hosted Mac mini was only in play to dodge GHA rate limits
(memory feedback_selfhosted_runner), but for these specific
workflows it came with real costs:
- Docker-push workflows emulated linux/amd64 from arm64 via QEMU —
every canvas + platform image build ran ~2-3x slower than native.
- Six PRs worth of keychain-avoidance hacks in publish-* because
`docker login` on macOS writes to osxkeychain unconditionally,
and the Mac mini's launchd user-agent keychain is locked.
- Homebrew pin-down environment variables (HOMEBREW_NO_*) sprinkled
everywhere to work around the shared /opt/homebrew symlink mess
on the runner.
- Setup-python@v5 couldn't write to /Users/runner, so ci.yml
python-lint resorted to a hand-rolled Homebrew python3.11 dance.
- Single runner → fan-out contention; CodeQL's 45-min analysis
fought the canvas publish for the one slot.
Changes across the 7 workflows:
- runs-on: [self-hosted, macos, arm64] → ubuntu-latest (every job)
- publish-canvas-image + publish-workspace-server-image:
drop the hand-rolled auths-map step + QEMU setup + buildx v4
→ docker/login-action@v3 + setup-buildx@v3. Linux + amd64
target = native build.
- canary-verify + promote-latest: replace `brew install crane` +
HOMEBREW_NO_* incantations with imjasonh/setup-crane@v0.4.
- codeql.yml: drop `brew install jq` — jq is preinstalled on
ubuntu-latest.
- ci.yml shellcheck: drop the self-hosted existence check —
shellcheck is preinstalled via apt.
- ci.yml python-lint: replace the Homebrew python3.11 path dance
with actions/setup-python@v5 (which works fine on GHA-hosted),
add requirements.txt caching while we're there.
- Remove stale comments referencing "the self-hosted runner",
"Mac mini", keychain, osxkeychain etc.
The self-hosted Mac mini remains in service for private-repo
workflows only. Memory feedback_selfhosted_runner updated to
reflect the public-repo scope carve-out.
Net -96 lines across the 7 files.

CI now detects which paths changed and skips irrelevant jobs:
- Platform (Go): only runs when platform/** changes
- Canvas (Next.js): only runs when canvas/** changes
- Python Lint: only runs when workspace-template/** changes
- Shellcheck: only runs when tests/e2e/** or scripts/** change
- E2E API: only runs when platform/** or tests/e2e/** change
Docs-only PRs (*.md, docs/**) skip all 5 jobs, saving ~15 min of
runner time per PR. Uses dorny/paths-filter for the CI workflow and
native paths: filter for the E2E workflow.

Job-level `concurrency.cancel-in-progress: false` only prevents sibling jobs
from killing each other — it does not protect the parent workflow run from
being cancelled when a new push arrives. Every PR push was cancelling the
in-progress E2E run, forcing manual `gh run rerun` across 7+ active PRs.
Fix: move e2e-api into `.github/workflows/e2e-api.yml` with a workflow-level
concurrency group (`e2e-api-${{ github.ref }}`, cancel-in-progress: false).
New pushes now queue behind the running E2E job instead of cancelling it.
Fast jobs (platform-build, canvas-build, shellcheck, python-lint) stay in
ci.yml and retain normal run-level cancellation for quick iteration feedback.
