The gap #225 left

ctrlrun-langchain merged with its directory, its distribution, its tests and green CI — and
no tag could have published it. publish.yml's trigger list and its case statement are
both explicit, neither had a row, and a tag naming it would have exited 1.

Nothing failed, because test_the_tag_an_adapter_release_needs_is_one_publish_yml_accepts
transcribes the version rule and never asks whether the workflow knows the adapter exists.

Three changes

1. publish.yml learns the adapter. A tag trigger and a case row.

2. ADAPTER_DIRECTORIES is derived, not listed. It was ("langgraph", "openai-agents"),
which is why none of the three parametrised packaging tests covered the new adapter. Derived
from the tree now — the same rule the guarantee ids follow, and for the same reason: a
hand-maintained list of subjects is a list that silently stops covering things.

3. A new test asserts every adapter in the tree is one a tag can release — both a trigger
and a case row. This is the guard that would have caught #225.

The consequence of deriving, which is the interesting part

Pointing the two PUBLISHED.toml guards at an adapter with no published side failed them,
correctly. An unpublished adapter has nothing on PyPI to compare against.

Absence is now recorded rather than tolerated:

unreleased = ["langchain"]

An adapter in neither a version table nor that list fails. A row that is simply missing would
read as "not published yet" — which is this file's guard dying in the one way it has not died
yet, after three releases of dying in other ways.

A release pass moves a name out of unreleased and adds its table after the upload
succeeds, which is the rule the file already states.

Evidence

Both new guards mutation-checked:

with langchain removed from `unreleased`:  FAILS (good)
with the tag trigger removed:              FAILS (good)

tests/test_packaging.py   53 passed, 2 skipped
ruff check / format       clean
publish.yml               valid YAML

The two skips are the PUBLISHED.toml guards on langchain, skipping with the reason that it
is recorded as never uploaded.

After this merges

adapters-langchain-1.0.0 becomes a tag that publishes. It also needs a PyPI pending
publisher
for ctrlrun-langchain, since the workflow uses trusted publishing:

Field Value
project ctrlrun-langchain
owner CTRLRun
repository ctrlrun
workflow publish.yml
environment pypi

That part is yours; nothing in this PR can do it.

Summary by CodeRabbit

  • New Features

    • Added release workflow support for publishing the LangChain adapter from dedicated version tags.
    • LangChain adapter releases are mapped to the correct distribution without publishing unrelated components.
    • Added release tracking for the LangChain adapter while it awaits its first publication.
  • Tests

    • Expanded packaging validation to automatically cover all available adapters.
    • Added checks for release triggers, packaging entries, and adapters awaiting publication.

…cannot

#225 merged an adapter no tag could publish. publish.yml's trigger list and its
case statement are both explicit and neither had a row, so a tag naming it would
have exited 1. Nothing failed, because the tag test transcribes the *version*
rule and never asked whether the workflow knows the adapter exists.

Three changes, the second of which is the one that matters:

ADAPTER_DIRECTORIES was a literal, which is why none of the three parametrised
packaging tests covered the new adapter. Derived from the tree now, the rule the
repo's own instructions already state for guarantee ids.

A new test asserts every adapter in the tree has both a tag trigger and a case
row in publish.yml. Mutation-checked: removing either fails it.

Deriving the list pointed the two PUBLISHED.toml guards at an adapter with no
published side, correctly. Absence is recorded now rather than tolerated, via an
`unreleased` list, and an adapter in neither a version table nor that list
fails. A row that is simply missing would read as "not published yet", which is
this file's guard dying in the one way it has not died yet. Mutation-checked the
same way.

📝 Walkthrough

Walkthrough

The publish workflow now supports LangChain adapter tags. Release metadata records LangChain as unreleased. Packaging tests discover adapters dynamically and validate workflow coverage and published-record handling.

Changes

LangChain adapter publishing

Layer / File(s) Summary
LangChain publish wiring
.github/workflows/publish.yml, adapters/PUBLISHED.toml
The workflow recognizes adapters-langchain-* tags and maps them to ctrlrun-langchain without publishing the kernel. PUBLISHED.toml records langchain as unreleased.
Dynamic adapter packaging validation
tests/test_packaging.py
Tests discover adapter directories from pyproject.toml files. They verify publish workflow coverage and handle adapters listed as unreleased or missing from published records.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to d6015

The packaging guard can miss accidental inclusion of LangChain in the kernel distribution; add the exclusion before merging.

48-48: 🩺 Stability & Availability | 🔵 Trivial

Confirm the PyPI trusted publisher before the first non-prerelease release.

When the packaged version is non-prerelease, an adapters-langchain-* tag maps to ctrlrun-langchain and invokes pypa/gh-action-pypi-publish in the pypi environment with OIDC. Ensure PyPI trusts CTRLRun/ctrlrun, .github/workflows/publish.yml, the pypi environment, and the ctrlrun-langchain project. Without that registration, the upload may be rejected. The repository does not establish the PyPI-side registration, so this is a release prerequisite rather than a confirmed current configuration defect.

The package job unpacks the sdist and runs the suite from inside it, and the
sdist prunes .github/ along with adapters/. The new test read the workflow
before looking, so it raised FileNotFoundError there instead of skipping.

Same guard the section's other documentation tests already use for adapters/,
and the reason is the same: these tests read repository files that are
deliberately absent from a distribution, so not finding them is the expected
state and not a failure.

Verified against a directory holding only tests/, where it skips, and against
the tree, where it still fails if a trigger is removed.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Include ctrlrun_langchain in the kernel-artifact exclusion. T136 rejects adapters/, ctrlrun_langgraph, and ctrlrun_openai_agents, but it does not reject ctrlrun_langchain. If a LangChain package enters a kernel artifact under ctrlrun_langchain/ without an adapters/ path, T136 can pass. Derive the forbidden package names from the discovered adapters, or add ctrlrun_langchain explicitly.
