PR #254 re-proposed mcp <2 -> <3 on 2026-09-08 at 10:08, six hours after
5839a7f landed an ignore written to stop exactly that. The ignore was not
missing and was not misspelled -- it reached the job intact, and did
nothing.

`update-types: ["version-update:semver-major"]` is derived from the
CURRENT version. Neither pip ecosystem here has one: every requirement is
a range (`mcp>=1.0,<2`) and Dependabot has no pip lockfile to resolve it
against. Root pip run 34213488343 prints the whole failure in three lines
-- "Checking if mcp  needs updating" with an empty version, "Ignored
versions:" with an empty list, "Updating mcp from  to 2.1.1". All six
conditions in that job behaved the same way: langchain-core,
langchain-text-splitters, langsmith, dagster, mcp and pyiceberg-core each
logged an empty ignore list. Only mcp produced a PR because it is the only
one whose latest release currently sits above its ceiling; the other five
were inert too, just not yet visibly so.

Each condition now states `versions: [">=<ceiling>"]`, evaluated against
the candidate release, so no current version is needed. Ceilings mirror
the upper bound each manifest declares: langchain-core >=2,
langchain-text-splitters >=2, langsmith >=1, dagster >=2, mcp >=2 (both
halves of the mirrored pin), pyiceberg-core >=0.8. No policy changed --
these are the same gates 5839a7f documented, expressed in the mechanism
that fires.

docker and github-actions keep `update-types`: an image tag and an action
ref are pinned current versions, so the update type is computable there.

tests/unit/test_dependabot_ignore_contract.py holds the shape (no
`update-types` in a pip ignore), ties each ceiling to the `<` bound parsed
out of pyproject.toml / integrations/pyproject.toml so a widened pin
cannot leave its ignore behind, and keeps the two halves of the mcp pin
equal. 6 passed; test_security_tooling_policy.py and
test_contract_dependencies.py still pass (27 passed).

Looks like mcp is no longer being updated by Dependabot, so this is no longer needed.
