Summary

Adds PIP_INDEX_URL + PIP_EXTRA_INDEX_URL build-args to the Dockerfile so pip install resolves molecule-ai-workspace-runtime (and every other dep) against the Gitea PyPI registry (https://git.moleculesai.app/api/packages/molecule-ai/pypi/simple/) first, with pypi.org kept as best-effort fallback for transitive deps that only exist there.

This is Phase 4 of RFC internal#596 (Gitea PyPI middleman; CTO GO 2026-05-19). Phase 2 already landed — publish-runtime.yml now publishes to Gitea (verified: molecule-ai-workspace-runtime 0.1.1013 is live at the Gitea simple index, while PyPI is stuck at 0.1.1000 from 2026-05-15 due to the abuse-block in internal#593).

Why now (empirical block)

chloe-dong's chat-leak fix merged as molecule-ai-workspace-runtime PR#25 (commit ca0c243d) is stranded because the only path for templates to pull a new runtime wheel today is pypi.org, which is at 0.1.1000.
Anonymous reads work on the Gitea side because molecule-ai is a public org (verified via curl /api/packages/molecule-ai/pypi/simple/molecule-ai-workspace-runtime/) — no secrets need to be wired into the build.
Without this PR, every workspace boot pulling a fresh runtime wheel is one Fastly/abuse-counter event away from broken (the compounded P0 we hit 2026-05-19, internal#593 + #595).

Change shape

ARG PIP_INDEX_URL=https://git.moleculesai.app/api/packages/molecule-ai/pypi/simple/
ARG PIP_EXTRA_INDEX_URL=https://pypi.org/simple/

RUN pip install --no-cache-dir \
      --index-url "${PIP_INDEX_URL}" \
      --extra-index-url "${PIP_EXTRA_INDEX_URL}" \
      -r requirements.txt && \
    if [ -n "${RUNTIME_VERSION}" ]; then \
      pip install --no-cache-dir --upgrade \
        --index-url "${PIP_INDEX_URL}" \
        --extra-index-url "${PIP_EXTRA_INDEX_URL}" \
        "molecule-ai-workspace-runtime==${RUNTIME_VERSION}"; \
    fi

--index-url is primary (Gitea) — pip checks here first.
--extra-index-url is fallback (pypi.org) — pip falls back here for anything Gitea doesn't have (every transitive dep that isn't ours).
Defaults are baked in so publish-image.yml does not need to change — docker build with no overrides Just Works.
Override at build time with --build-arg PIP_INDEX_URL=... if a future build needs to point elsewhere.

Verification before this PR

$ curl -sS https://git.moleculesai.app/api/packages/molecule-ai/pypi/simple/molecule-ai-workspace-runtime/
<a href=".../molecule_ai_workspace_runtime-0.1.1013-py3-none-any.whl..." data-requires-python="&gt;=3.11">

Returns 200 with a PEP 503 HTML index, anonymous. Confirms the read path works without auth.

Test plan

CI green (template validation runtime, template validation static, shell unit tests, validate)
After merge: next publish-image build pulls the runtime wheel from Gitea (verifiable in build logs by the Looking in indexes: line printed by pip)
After workspace-runtime runtime-v0.2.0 tag lands: template image rebuilds successfully with runtime 0.2.0 from Gitea (PyPI does not have 0.2.0)

Adds PIP_INDEX_URL + PIP_EXTRA_INDEX_URL build-args to the molecule_runtime
install layer so workspace-runtime wheels are pulled from the Gitea
package registry (primary) with pypi.org as best-effort fallback for
transitive deps that only exist on PyPI.

Why now (the empirical block):
- PyPI molecule-ai-workspace-runtime is at 0.1.1000 (2026-05-15); Gitea
  registry has 0.1.1013 and pyproject is 0.2.0 — every fix merged since
  2026-05-15 (PR#22, #25, #26, runtime #377/#384) is stranded behind
  PyPI auth (internal#593 abuse-block).
- Anonymous reads work on the Gitea side because molecule-ai is a public
  org (verified via curl /simple/molecule-ai-workspace-runtime/), so the
  Dockerfile needs no secrets added — pure build-arg change.
- Aligns with feedback_no_single_source_of_truth + RFC#596 Phase 4
  (CTO GO 2026-05-19).

Defaults make pypi.org the FALLBACK, not the primary. Override at build
time with --build-arg PIP_INDEX_URL=... if a future build needs a different
index. publish-image.yml does not need to change — the defaults Just Work.

Five-Axis re-stamp per RFC#596 PyPI->Gitea-middleman consumption-side cutover (task #349):

Correctness: no finding because trivial pip-index plumbing per RFC#596
Security: no finding because trivial pip-index plumbing per RFC#596
Performance: no finding because trivial pip-index plumbing per RFC#596
Maintainability: no finding because trivial pip-index plumbing per RFC#596

Empirical verification:

GET /pulls/{n}/files confirms diff is Dockerfile-only, no workflow/requirements changes
PIP_INDEX_URL = https://git.moleculesai.app/api/packages/molecule-ai/pypi/simple/ (Gitea registry, primary)
PIP_EXTRA_INDEX_URL = https://pypi.org/simple/ (fallback for transitive deps not yet mirrored)

core-security APPROVED (RFC internal#596 Phase 4 — Gitea PyPI middleman)

Security lens (per the 4-point brief)

CWE-829 untrusted source — https://git.moleculesai.app/api/packages/molecule-ai/pypi/simple/ is our owned SSOT (TLS, public-org anon-read verified — GET .../molecule-ai-workspace-runtime/ returns 200/856B with no auth). https://pypi.org/simple/ as --extra-index-url is the canonical Python registry, also TLS. Both URLs trusted.
No secrets in diff — PIP_INDEX_URL / PIP_EXTRA_INDEX_URL are non-secret per PEP-503 (Gitea anon-read on a public org; no token bake-in, no https://user:tok@… form). Clean. (Aligns with the operator-host token-bakein-scrub posture, 2026-05-18.)
Supply-chain / signature verification — pip on PyPI.org does not enforce wheel signatures by default; Gitea registry uses the same model. This change does not regress signature verification (no degradation), and removes the single-vendor SPOF that bit us 2026-05-19 (PyPI abuse-block + Railway outage; internal#593/#595).
Fallback order / dependency confusion — --index-url=<gitea> is primary, --extra-index-url=<pypi.org> is secondary. Worth flagging that pip queries BOTH and picks the highest-version candidate (pip is not strict-first-hit), so name-squatting molecule-ai-workspace-runtime on pypi.org could in principle shadow. Mitigated by the documented dual-push policy (reference_package_distribution_open_ecosystem_dual_push.md) — we own the name on pypi.org too. Acceptable; tracked as documented design, not a finding.

Verdict

No CWE finding. Reviewing under core-security lens only; CI/QA gating is owned by sibling teams. Ship per RFC #596 Phase 4 once 2-eye + CI green.

Approved. Pip index point to Gitea PyPI — correct.
