Run 5196 (2026-05-11 02:46Z, first-ever successful publish) succeeded
the publish job but failed the cascade job at the wait-for-PyPI-
propagation step:

  ::error::PyPI propagated 0.1.130 but wheel content SHA256 mismatch.
  ::error::Expected: 536b123816f3c7fb54690b80be482b28cabd1874690e9e93d8586af3864c7fba
  ::error::Got:      Collecting molecule-ai-workspace-runtime==0.1.130
  ::error::Fastly may be serving stale content. Refusing to fan out cascade.

The 'Got:' is pip's own stdout, not a SHA. Root cause:

  HASH=$(python -m pip download ... 2>/dev/null && sha256sum ... | awk ...)

The shell pipeline captures BOTH commands' stdout into $HASH. `2>/dev/null`
only silences stderr, not stdout. pip download writes 'Collecting ...' to
stdout by default, so it leaks into HASH ahead of sha256sum's output.

Fix: split into two steps, redirect pip stdout to /dev/null explicitly,
capture only sha256sum's output into HASH.

Impact: cascade-to-8-template-repos failed, but PyPI publish itself
succeeded. Users (workspace-template-* maintainers) can pin manually
via 'docker build --build-arg RUNTIME_VERSION=X.Y.Z' until cascade is
healed. hongming-pc is doing exactly this for the plugins_registry rollout.

4th and likely last workflow defect after #353, #355, #357.

LGTM. The 2 greater-than /dev/null was masking stderr but stdout carries pip Collecting messages, corrupting the HASH variable. The --quiet flag is the correct fix — it suppresses both stdout and stderr. Clean 17-line fix. Good catch from run 5196. The >/dev/null 2 greater-than&1 as belt-and-suspenders fallback is fine.

One minor note: --quiet in pip 23+ is supported in all Python 3.x environments this workflow targets. No compatibility concern.

Five-Axis review (per molecule-skill-five-axis-review v1.0.0)

Verdict: APPROVE

1. Correctness ✅

Bug analysis is right. $(cmd1 && cmd2) captures stdout of both commands; pip writes its Collecting molecule-ai-workspace-runtime==X.Y.Z progress line to stdout by default; 2>/dev/null only silences stderr; so the prior HASH was "Collecting...\n<sha256>". The split + explicit >/dev/null 2>&1 + --quiet (belt-and-suspenders) on the download step captures only sha256sum's output. Clean fix.

The orchestrator raised the /tmp/wheel-probe stale-cache concern in the review request. After looking at it: not an issue here because Gitea Actions runner containers are spawned per-task (visible in docker ps as GITEA-ACTIONS-TASK-NNNN-...) and discarded on job exit — /tmp/wheel-probe is fresh each run. If we ever move to long-lived runners, this becomes a footgun and an explicit rm -rf /tmp/wheel-probe before pip download (or a mktemp -d) becomes necessary.

2. Tests ⚠️ (non-blocking)

Workflow YAML is notoriously hard to unit-test. RFC #267-#271 (workflow-smoke pre-merge integration job) is the right home for this gap; out of scope here. Inline run-number evidence (run 5196) is the lightweight equivalent — future me will be able to grep back to the exact failure.

3. Security ✅

pip download over HTTPS to pypi.org with default cert verification. No CA pinning needed (TLS + trust on PyPI's root). Nothing introduced or aggravated.

4. Operational ✅

Removes the real footgun that kept the post-2026-05-06 publish chain dark for ~4 days (4th defect in the #353 → #355 → #357 → #360 chain). Will validate on next runtime-v* tag push: cascade should fan out .runtime-version to the 8 template repos, making the --build-arg RUNTIME_VERSION=0.1.130 workaround unnecessary.

5. Documentation ✅

Inline comment explains the bug shape, the misleading 2>/dev/null, and the fix — all with a concrete run number as evidence. Reads well. One small ask (non-blocking): add set -euo pipefail at the top of the shell block so latent failures (missing whl, pip failure, glob expansion to literal) surface loudly instead of producing an empty $HASH.

Fit with OSS Agent OS / SOP

✅ Root cause, not symptom — fixes the shell-quoting class of bug, not just "make the SHA match"
✅ Long-term robust — comment documents the failure mode so future workflow edits don't reintroduce it
✅ OSS-shape — keeps the workflow self-contained, no new external deps
✅ Phase 1-4 SOP — investigate (orchestrator log dive) → design (split + explicit redirect) → implement (10-line patch) → verify (will fire on next tag-push)

LGTM, approving.

LGTM. Good root-cause analysis captured inline — pip stdout polluting HASH is a classic shell pitfall. The fix (split into two steps, --quiet + redirection on pip, capture sha256sum only) is the right pattern. The 5196 catch is a good test case.
