What

Add python-multipart>=0.0.27 to the PYPROJECT_TEMPLATE.dependencies list in scripts/build_runtime_package.py — the actual SSOT for molecule-ai-workspace-runtime's PyPI dist.

7 LoC, single file.

Why

Hermes workspace PDF (44KB) upload returns opaque 400 "failed to parse multipart form". Forensic a78762a0 (2026-05-19): python-multipart is absent from the published runtime wheel (0.1.17), so Starlette's Request.form() raises AssertionError when parsing multipart bodies. Every template that pip-installs molecule-ai-workspace-runtime is affected (Hermes confirmed; openclaw + future templates latent).

Chloe (Hermes user) is currently blocked — P0.

Why THIS file (SSOT trace)

workspace/requirements.txt already has the canonical pin from Dependabot PR #2526 months ago:

python-multipart>=0.0.27

But that file is excluded from the PyPI build path. Per scripts/build_runtime_package.py:125:

EXCLUDE_FILES = {
    ...
    "requirements.txt",
    ...
}

The published wheel's deps come from the hardcoded PYPROJECT_TEMPLATE on line 253. Two manifests, zero enforced parity = silent drift. That's the bug.

Why not edit the mirror repo directly

molecule-ai-workspace-runtime PR #18 made the analogous edit to the mirror's pyproject.toml and was correctly rejected by mirror-guard — the file is regenerated from PYPROJECT_TEMPLATE on every runtime-v* tag push. Direct edits get clobbered.

Closing molecule-ai-workspace-runtime#18 in favor of this PR.

Class drift (out-of-scope follow-up)

workspace/requirements.txt (monorepo Docker image deps) and PYPROJECT_TEMPLATE (PyPI wheel deps) are two separate manifests with no enforced parity. A follow-up RFC should consider:

• (a) build_runtime_package.py derives deps from workspace/requirements.txt (single source), OR
• (b) A lint that asserts the two are aligned at CI time.

Out of scope for this P0 fix — would expand the diff and delay Chloe's unblock.

Verification path for CTO (post-merge)

1. Merge this PR → push tag runtime-v0.1.18 on main (or publish-runtime-autobump will do it).
2. publish-runtime.yml runs:
   • Builds wheel via build_runtime_package.py — pyproject.toml now contains python-multipart>=0.0.27.
   • twine upload to PyPI (with the SHA256 self-verification round-trip).
   • Cascade pins .runtime-version=0.1.18 across the 8 templates incl. Hermes.
3. Restart Chloe-Hermes workspace (forces re-pull of latest runtime).
4. Retry PDF upload via canvas → expect 200 with {"files":[{"uri":"workspace:/...",...}]}.

fix(workspace/deps): pin python-multipart>=0.0.27 for chat-upload Starlette parser ... 940bae15a6

Add python-multipart to the PYPROJECT_TEMPLATE dependencies in
scripts/build_runtime_package.py — the actual SSOT for
molecule-ai-workspace-runtime's PyPI dist (not the sibling repo's
pyproject.toml, which is regenerated from this template on every
runtime-v* tag push per publish-runtime.yml).

Root cause (forensic a78762a0, 2026-05-19): Hermes workspace PDF upload
returned opaque 400 "failed to parse multipart form" because the
published PyPI runtime (0.1.17) lacks python-multipart. Without it,
Starlette's Request.form() raises AssertionError on multipart bodies,
which /internal/chat/uploads/ingest surfaces as a 400.

workspace/requirements.txt already pins this (Dependabot PR #2526
landed it months ago for the monorepo Docker image), but the PyPI
build path bypasses workspace/requirements.txt entirely — it uses the
hardcoded PYPROJECT_TEMPLATE on line 253. That divergence is the bug.

Class drift note: workspace/requirements.txt and the PyPI deps list
are two separate manifests with no enforced parity. A follow-up RFC
should consider either (a) having build_runtime_package.py derive
deps from workspace/requirements.txt, or (b) a lint that asserts the
two are aligned. Out of scope for this P0 fix.

Companion: workspace-runtime#18 was correctly rejected by mirror-guard
(direct edits to the mirror are reverted by the next publish). That
PR is closed in favor of this one.

Verification path after merge:
  1. Tag runtime-v0.1.18 on main (or trigger publish-runtime-autobump).
  2. publish-runtime.yml builds wheel via build_runtime_package.py →
     pyproject.toml now contains python-multipart>=0.0.27.
  3. twine uploads to PyPI; cascade fans out .runtime-version to
     templates including Hermes.
  4. Restart Chloe-Hermes workspace; retry PDF upload via canvas.
  5. Expect HTTP 200 with {"files":[{"uri":"workspace:/...",...}]}.

core-qa APPROVE — mc#1578 review-relay

QA review:

• test plan: leaf dep-floor pin; behaviour is verified end-to-end by chat-upload integration (currently surfacing the 400 forensic a78762a0 captured). Once runtime-v0.1.18 ships and Chloe-Hermes restarts on the new wheel, the PDF upload path is the live signal.
• risk: very low — pure pyproject template addition; pin is already mirrored in workspace/requirements.txt (no contract drift). Build runs unit + integration suites — all green on head 940bae15.
• regression watch: publish-runtime-autobump.yml does NOT fire on scripts/** — manual runtime-v0.1.18 tag is the canonical trigger; flagged in brief, captured in post-merge step.
