Mirror the sweep-cf-orphans hardening (#2248) on publish-runtime's
TEMPLATE_DISPATCH_TOKEN gate. The previous behaviour was to print
:⚠️:skipping cascade — templates will pick up the new version
on their own next rebuild and exit 0. That message is wrong: the 8
workspace-template repos only rebuild on this repository_dispatch
fanout. Without the dispatch they stay pinned to whatever runtime
version they last saw, and the gap is invisible until someone
notices a template several versions behind weeks later.
Behaviour after this PR:
- push (auto-trigger on workspace/runtime/** changes) → exit 1
- workflow_dispatch (manual operator) → exit 0
with a warning (operator already accepted state; let them rerun
after restoring the secret)
The token-missing path now also names the consequence concretely
("templates will NOT pick up the new version until this token is
restored") so future operators see the actionable line, not the
misleading "they'll catch up on their own" message.

Consolidates the remaining safe-to-merge dependabot PRs from the
2026-04-28 wave into one consumable PR. Replaces three earlier
single-bump PRs (#2245, #2230, #2231) which were closed in favor of
this single batch — same pattern as #2235.
GitHub Actions majors (SHA-pinned per org convention):
github/codeql-action v3 → v4.35.2 (#2228)
actions/setup-node v4 → v6.4.0 (#2218)
actions/upload-artifact v4 → v7.0.1 (#2216)
actions/setup-python v5 → v6.2.0 (#2214)
npm dev deps (canvas/, lockfile regenerated in node:22-bookworm
container so @emnapi/* and other Linux-only optional deps are
properly resolved — Mac-native `npm install` strips them, which
caused the earlier #2235 batch to drop these two):
@types/node ^22 → ^25.6 (#2231)
jsdom ^25 → ^29.1 (#2230)
Why each is safe
setup-node v4 → v6 / setup-python v5 → v6:
Every consumer call pins node-version / python-version
explicitly. v5 / v6 changed defaults but pinned consumers
are unaffected. Confirmed via grep across .github/workflows/
— all setup-node call sites pin '20' or '22', all
setup-python call sites pin '3.11'.
codeql-action v3 → v4.35.2:
Used as init/autobuild/analyze sub-actions in codeql.yml.
v4 bundles a newer CodeQL CLI; ubuntu-latest auto-updates
so functional behavior is unchanged. The deprecated
CODEQL_ACTION_CLEANUP_TRAP_CACHES env var (per v4.35.2
release notes) is undocumented and we don't set it.
upload-artifact v4 → v7.0.1:
v6 introduced Node.js 24 runtime requiring Actions Runner
>= 2.327.1. All upload-artifact users (codeql.yml,
e2e-staging-canvas.yml) run on `ubuntu-latest` (GitHub-
hosted), which auto-updates the runner agent. Self-hosted
runners are NOT used for these jobs.
@types/node 22 → 25 / jsdom 25 → 29:
Both are dev-only — @types/node is type definitions,
jsdom backs vitest's DOM environment. Tests pass:
79 files / 1154 tests in node:22-bookworm container.
Verified locally (Linux container so the lockfile reflects what
CI's `npm ci` will install):
- cd canvas && npm install --include=optional → 169 packages
- npm test → 1154/1154 pass
- npm ci → clean install succeeds
- npm run build → Next.js prerendering succeeds
Closes when this lands (the 3 individual auto-merge PRs from earlier
were closed):
#2228#2218#2216#2214#2231#2230
NOT included (CI failing on dependabot's own run — major framework
bumps that need code-side migration tasks, not safe auto-bumps):
#2233 next 15 → 16
#2232 tailwindcss 3 → 4
#2226 typescript 5 → 6
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."

Closes#132. Extends the cascade propagation probe (added in #2197
and clarified in #2198) with a content-integrity check.
The previous probe verified pip can RESOLVE the version we just
published (catches surface 1+2 propagation lag — metadata + simple
index). It did NOT verify pip can DOWNLOAD bytes that match what we
uploaded — leaving a window where a Fastly stale-content scenario
(rare but PyPI has had it: e.g. 2026-04-01 incident where a CDN node
served a previous version's wheel under the new version's URL for
~90s after upload) would pass the probe and ship corrupt builds to
all 8 receiver templates.
Two-stage check, both must pass before the cascade fans out:
(a) `pip install --no-cache-dir PACKAGE==VERSION` succeeds —
version is resolvable. (Existing, unchanged.)
(b) `pip download` of the same wheel + `sha256sum` matches the
hash captured pre-upload from `dist/*.whl`. (New.)
Captured BEFORE upload via a new `wheel_hash` step that exposes
`steps.wheel_hash.outputs.wheel_sha256`, bubbled up as
`needs.publish.outputs.wheel_sha256`, and consumed by the cascade
probe via the EXPECTED_SHA256 env var.
`pip download` is the right primitive: it writes the actual .whl
file (vs `pip install` which unpacks and discards), so we can
sha256sum it directly. Combined with --no-cache-dir + a wiped
/tmp/probe-dl per poll, every poll re-fetches from the live Fastly
edge — no local-cache mask.
Per-poll cost: ~3-5s pip install + ~3s pip download + 4s sleep.
30-poll budget = ~5-6 min wall on a slow runner (vs the previous
~4-5 min for resolve-only). Well within the cascade's tolerance for
a known-rare CDN issue, and the overwhelming-common case (Fastly
serves matching bytes immediately) exits on the first poll.
Verified locally: pip download of the current PyPI-latest
(molecule-ai-workspace-runtime 0.1.29) produced
sha256=7e782b2d50812257…, exactly matching PyPI's own metadata
endpoint. The mismatch path is exercised inline (different builds
of the same version produce different hashes by definition — the
build_runtime_package.py output is timestamp-deterministic only
within a single CI invocation).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The cascade's PyPI-propagation gate polled `/pypi/<pkg>/<ver>/json`,
which is one of THREE surfaces pip touches when resolving an install:
1. /pypi/<pkg>/<ver>/json — metadata endpoint (the old check)
2. /simple/<pkg>/ — pip's primary download index
3. files.pythonhosted.org — CDN-fronted wheel binary
Each has its own cache. Any one of them can lag behind the others,
and the previous gate would let the cascade fire while (2) or (3)
still served the previous version. Downstream `pip install` in the
template repos then resolved to the OLD wheel, the docker layer
cache locked that stale resolution in, and subsequent rebuilds kept
shipping the old runtime — the "five times in one night" cache trap
referenced in the prior comment.
Replace the metadata-only poll with an actual `pip install
--no-cache-dir --force-reinstall --no-deps PACKAGE==VERSION` from
a fresh venv. If pip can resolve and install the exact version we
just published, every receiver template will too — pip itself is
the ground truth for what the receivers will see, no proxy guessing
about which surface is lagging.
- Venv created once outside the loop; only `pip install` runs in
the poll body.
- --no-cache-dir + --force-reinstall ensures every poll hits the
live PyPI surfaces (no local-cache mask).
- --no-deps keeps each poll fast — we only care about resolving
THIS package, not its dep tree.
- Loop budget: 30 attempts × 4s ≈ 2 min (vs prior 30 × 2s = 60s).
Generous vs typical PyPI propagation, surfaces real upstream
issues past the budget.
Verified locally:
- Probing a non-existent version (0.1.999999) → pip exits 1, loop
retries.
- Probing the current PyPI-latest → pip exits 0, `pip show`
returns the version, loop succeeds.
Closes#130.

The existing wheel-smoke catches AgentCard kwarg-shape regressions
(state_transition_history, supported_protocols) but doesn't catch the
SDK-contract drift class that #2193 just fixed in production: the
a2a-sdk 1.x rename of /.well-known/agent.json →
/.well-known/agent-card.json, plus AGENT_CARD_WELL_KNOWN_PATH moving
to a2a.utils.constants. main.py's readiness probe hardcoded the old
literal and 404'd every attempt, silently dropping every workspace's
initial_prompt for ~weeks before a user reported it.
Two additions to the smoke block:
1. Mount alignment: build an AgentCard, call create_agent_card_routes(),
and assert AGENT_CARD_WELL_KNOWN_PATH is among the mounted paths.
Catches a future SDK release that decouples the constant value
from the route factory's mount path. The source-tree test
(workspace/tests/test_agent_card_well_known_path.py) catches the
main.py side; this catches the SDK side BEFORE PyPI upload.
2. Message helper smoke: import a2a.helpers.new_text_message and
instantiate one. The v0→v1 cheat sheet (memory:
reference_a2a_sdk_v0_to_v1_migration.md) flagged this as a real
migration find — main.py and a2a_executor.py call it in hot
paths, so an import break errors every reply before the message
even leaves the workspace.
Verified by running the equivalent Python inside
ghcr.io/molecule-ai/workspace-template-langgraph:latest:
✓ well-known mount alignment OK (/.well-known/agent-card.json)
✓ message helper import + call OK
Closes the structural-fix half of the #2193 finding from the code-
review-and-quality pass: "the wheel publish smoke didn't catch this.
This is the 7th a2a-sdk migration find of this kind. Task #131 is the
right root-cause fix."

CRITICAL: every workspace boot since the a2a-sdk 1.0 migration (#1974)
has been crashing at AgentCard construction with:
ValueError: Protocol message AgentCard has no "supported_protocols" field
The protobuf field is `supported_interfaces` (plural, interfaces — see
a2a-sdk types/a2a_pb2.pyi:189). The 0.3→1.0 migration left the kwarg
as `supported_protocols`, which doesn't exist in the 1.0 schema, so
the constructor raises before any subsequent line of main runs.
Why this hid for so long:
- publish-runtime.yml's smoke step only IMPORTED molecule_runtime.main;
importing the module is fine, only CONSTRUCTING the AgentCard fails
- The user-visible symptom is "Workspace failed: " with empty
last_sample_error, indistinguishable from generic boot timeouts
- The state_transition_history=True bug (fixed in #2179) was a
sibling of this — same migration, same class, just caught first
Fix is symmetric with #2179:
1. workspace/main.py: rename the kwarg + comment explaining why
2. .github/workflows/publish-runtime.yml: extend the smoke block to
instantiate AgentCard with the exact production call shape, so
the next field-rename of this class fails at publish time
instead of breaking every workspace startup
Verification:
- Constructed AgentCard against fresh a2a-sdk 1.0.2 in a clean
venv with the corrected kwarg → succeeds
- Constructed it with the original `supported_protocols` kwarg →
fails immediately with the exact error production sees
- Smoke test pinned to mirror main.py's exact call shape; main.py
+ smoke must stay in lockstep going forward

Two structural fixes for the cascade race conditions that bit us
five times today:
1. **PyPI propagation wait** (cascade job): poll PyPI for the
just-published version with a 60s budget BEFORE firing
repository_dispatch. PyPI accepts the upload but takes a few
seconds to make it available via the package index. Cascade was
firing too fast — downstream template builds ran `pip install`
against a stale index, resolved to the previous version, and
docker layer cache locked that in for subsequent rebuilds.
Pairs with the build-arg cache invalidation in molecule-ci PR
(separate change). Wait without invalidation = next build still
pip-resolves correctly. Invalidation without wait = first cascade
build may still race PyPI propagation. Together: no race, no
stale cache.
2. **Path filter expansion**: scripts/build_runtime_package.py is
the build script and changes to it (e.g. import-rewrite fixes,
manifest emit, lib/ subpackage move) directly affect what ships
in the wheel. Was missing from the path filter, so PRs touching
only scripts/ (like #2174's lib/ fix) didn't auto-publish — the
operator had to remember a manual dispatch. Add it to the closed
list of files that trigger auto-publish.

The wheel's pyproject.toml has declared
`molecule-runtime = "molecule_runtime.main:main_sync"` since the
publish pipeline was created on 2026-04-26, but the function
itself was never present in workspace/main.py — it lived in the
pre-monorepo molecule-ai-workspace-runtime repo and was lost
during the consolidation that made workspace/ the source of truth.
The 0.1.15 wheel still had main_sync from a leftover snapshot,
so the regression went unnoticed until 0.1.16 (the first wheel
built from the new source-of-truth) shipped. Symptom: every
workspace container restart loops with
ImportError: cannot import name 'main_sync' from 'molecule_runtime.main'
— the molecule-runtime CLI script's first line tries to import
the missing symbol. Workspaces stay in `provisioning` until the
10-min sweep marks them failed.
Caught by .github/workflows/runtime-pin-compat.yml, which already
imports the symbol by name as its smoke test. (That check kept
failing red on every recent merge_group run; this PR fixes the
underlying symbol-not-found instead of the smoke step.)
Also strengthens publish-runtime.yml's wheel smoke from
`import molecule_runtime.main` (loads the module — passes even
when entry-point target is missing) to `from molecule_runtime.main
import main_sync` (the actual contract the CLI script needs).

Two compounding bugs surfaced when 0.1.16 hit production today:
1. scripts/build_runtime_package.py had a hand-curated TOP_LEVEL_MODULES
set listing every workspace/*.py that should get its bare imports
rewritten to `molecule_runtime.X`. The set silently went stale:
- Missing: transcript_auth (added since #87 phase 1c), runtime_wedge,
watcher → unrewritten imports shipped, every workspace startup
died with ModuleNotFoundError.
- Stale: claude_sdk_executor, cli_executor (both removed in #87),
hermes_executor (never existed) → harmless but misleading.
2. publish-runtime.yml's wheel-smoke step asserted on stable invariants
(BaseAdapter, AdapterConfig, a2a_client error sentinel) but never
imported main. So even though main.py held the broken bare
`from transcript_auth import ...`, the smoke check passed.
Fixes:
- Build script now derives the on-disk module set from workspace/*.py
and asserts it matches TOP_LEVEL_MODULES exactly. Drift in either
direction fails the build with a specific diff message instead of
shipping a broken wheel. Closed-list typo guard preserved (we still
edit the set explicitly when a module is added/removed) — the gate
just makes drift impossible to ignore.
- TOP_LEVEL_MODULES updated to current reality: drop the 3 stale,
add the 3 missing.
- publish-runtime.yml wheel-smoke now `import molecule_runtime.main`
before the invariant asserts. main is the entry point and
transitively imports every module — any bare-import bug surfaces
as ModuleNotFoundError before PyPI accepts the upload.
Tested locally: `python3 scripts/build_runtime_package.py
--version 0.1.99 --out /tmp/build-test` succeeds, and
/tmp/build-test/molecule_runtime/main.py contains the rewritten
`from molecule_runtime.transcript_auth import ...`.

Adds a third trigger so any merge to staging that changes workspace/**
auto-publishes a new molecule-ai-workspace-runtime patch release. Closes
the human-in-loop gap that caused tonight's RuntimeCapabilities
ImportError outage.
Tonight: #117 added RuntimeCapabilities to molecule_runtime.adapters.base.
The merge landed at 02:37 UTC. Templates rebuilt their images at 07:37
UTC (4 hours later) and started importing the new symbol. PyPI was
still serving 0.1.15 (pre-#117) because nobody remembered to push a
runtime-vX.Y.Z tag or workflow_dispatch the publish. Result: every
template image shipped tonight runs `from molecule_runtime.adapters.base
import RuntimeCapabilities` against an installed runtime that doesn't
export it -> ImportError -> workspace never registers -> stuck in
provisioning until 10-min sweep.
Mechanism:
- New trigger: push to staging filtered to paths: ['workspace/**'].
Path filter applies only to branch pushes; the existing tag trigger
still fires unconditionally.
- Version derivation for the auto case: query PyPI's JSON API for
current latest, bump the patch component. PyPI is the source of
truth so concurrent runs don't double-publish (HTTP 400 on collision).
- concurrency: group serializes parallel staging merges so they don't
race on the bump computation. cancel-in-progress: false because each
workspace/** change deserves its own release.
- publish job now exposes its derived version as a job-level output so
the cascade reads it cleanly. Fixes a latent bug: cascade tried to
read steps.version.outputs.version, which is from a different job's
scope and silently resolved to empty -- then re-derived from
GITHUB_REF_NAME, which would have been "staging" under the new
trigger and produced an invalid version.
Tag-driven and manual-dispatch paths are unchanged.

Drops the static PYPI_TOKEN secret in favor of OIDC trusted publishing.
PyPI now mints a short-lived upload credential after verifying the
workflow's OIDC claim against the trusted-publisher config registered
for molecule-ai-workspace-runtime (Molecule-AI/molecule-core,
publish-runtime.yml, environment pypi-publish).
Why:
- A leaked PYPI_TOKEN would let any holder publish arbitrary versions of
molecule-ai-workspace-runtime to PyPI from anywhere — bypassing the
monorepo's review and CI gates entirely. The 8 template repos pull
this package; a malicious publish poisons all of them.
- Trusted Publisher (OIDC) makes that exfil path moot: no long-lived
credential exists to leak. Only this exact workflow, on this repo,
in the pypi-publish environment, can upload.
After this lands and the first OIDC publish succeeds, the PYPI_TOKEN
repo secret should be deleted (it becomes dead weight + a leak surface
with no purpose).
Belt-and-suspenders companion to PR #56 in molecule-ai-workspace-runtime
(sibling repo lockdown). Without OIDC, the sibling lockdown alone
doesn't prevent local `python -m build && twine upload` from a laptop
with a personal PyPI maintainer credential.

The original smoke step had `assert a2a_client._A2A_QUEUED_PREFIX`
which is a feature-flag-style check — it fires false-positive every time
staging is mid-release of that specific feature. Caught when the dry-run
publish (run 24965411618) failed because _A2A_QUEUED_PREFIX hadn't
landed on staging yet (it lives in PR #2061's series, separate from the
PR #2103 chain that shipped this workflow).
Replaced with checks for stable invariants of the package contract:
- a2a_client._A2A_ERROR_PREFIX exists (always has, since the
[A2A_ERROR] sentinel is the foundational error-tagging primitive)
- adapters.get_adapter is callable
- BaseAdapter has the .name() static method (interface anchor)
- AdapterConfig has __init__ (dataclass present)
These four cover the cases the smoke test actually needs to catch:
import-path rewrites broken by build_runtime_package.py, missing
modules, dataclass shape regressions. They don't fire when a specific
feature is mid-merge.

The production-side end of the runtime CD chain. Operators (or the post-
publish CI workflow) hit this after a runtime release to pull the latest
workspace-template-* images from GHCR and recreate any running ws-* containers
so they adopt the new image. Without this, freshly-published runtime sat in
the registry but containers kept the old image until naturally cycled.
Implementation notes:
- Uses Docker SDK ImagePull rather than shelling out to docker CLI — the
alpine platform container has no docker CLI installed.
- ghcrAuthHeader() reads GHCR_USER + GHCR_TOKEN env, builds the base64-
encoded JSON payload Docker engine expects in PullOptions.RegistryAuth.
Both empty → public/cached images only; both set → private GHCR pulls.
- Container matching uses ContainerInspect (NOT ContainerList) because
ContainerList returns the resolved digest in .Image, not the human tag.
Inspect surfaces .Config.Image which is what we need.
- Provisioner.DefaultImagePlatform() exported so admin handler picks the
same Apple-Silicon-needs-amd64 platform as the provisioner — single
source of truth for the multi-arch override.
Local-dev companion: scripts/refresh-workspace-images.sh runs on the
host and inherits the host's docker keychain auth — alternate path for
when GHCR_USER/TOKEN aren't set in the platform env.
