Summary

.github/dependabot.yml does not parse, so Dependabot has been opening no pull requests at all. It set versioning-strategy: "widen" for pip, which that ecosystem does not accept. GitHub's .github/dependabot.yml check on any pull request that touches the file says:

The property '#/updates/0/versioning-strategy' value "widen" did not match one of the following values: lockfile-only, auto, increase, increase-if-necessary

(widen is valid for npm and Composer.) I introduced it in the contributor-intake change (#964) and did not see the check, because that run did not surface it until a later pull request touched the file. The first weekly run is Monday 2026-10-19, so this should merge before then.

Changes

  • .github/dependabot.yml: the key is removed (the default is auto) and the header comment says why. The comment also records the open question: ForgeLM declares bounded ranges with no lockfile, so auto may raise a floor the ceiling already covers instead of admitting a new major. Look at the first pull requests and tighten then.
  • tests/test_packaging.py::test_dependabot_config_uses_only_values_the_pip_ecosystem_accepts: parses the file and fails on a pip strategy outside the accepted four. It fails against the old file.
  • CHANGELOG.md: one entry.

Type

  • Bug fix (CI configuration)

Testing

  • The full CLAUDE.md gauntlet from a clean worktree of this branch: exit 0.
  • GitHub's own .github/dependabot.yml check on this pull request should turn green; that is the real confirmation, and it is the only check that can tell.

Checklist

  • CHANGELOG entry under [Unreleased]
  • Test added

Summary by Sourcery

Restore valid Dependabot configuration for pip dependency updates and guard against unsupported versioning strategies.

Bug Fixes:

  • Fix the Dependabot configuration so the pip update block is accepted by GitHub and Dependabot can resume opening dependency updates.

Enhancements:

  • Document the pip versioning-strategy constraint and the need to review Dependabot’s initial pull requests.

Tests:

  • Add packaging coverage that validates pip Dependabot strategies against GitHub’s accepted values and ensures the pip update block remains configured.

Summary by CodeRabbit

  • Bug Fixes
    • Corrected the Python dependency update settings to use supported versioning options, preventing configuration rejection.
  • Tests
    • Added a check to ensure Python dependency updates use valid versioning settings.
  • Documentation
    • Updated the changelog with the configuration correction.

…den for pip

GitHub's Dependabot check on every pull request that touched the file reported:
  The property '#/updates/0/versioning-strategy' value "widen" did not match one of the following values:
  lockfile-only, auto, increase, increase-if-necessary
so the whole configuration was rejected and Dependabot opened nothing. 'widen' is valid for npm and Composer, not for pip. The key is
removed (the default is auto), the header comment says why, and a test pins the values the pip ecosystem accepts (it fails against the old
file).

Reviewer's Guide

This PR restores Dependabot operation by removing the invalid widen strategy from the pip configuration, documenting the implications of falling back to auto, and adding a regression test to prevent unsupported pip strategies from breaking the file again.

.github/dependabot.yml
Added regression coverage that validates pip Dependabot strategies against GitHub’s accepted values.
  • Loads .github/dependabot.yml with YAML parsing and rejects unsupported pip strategies.
  • Ensures the pip update block remains present.

📝 Walkthrough

The pip Dependabot configuration no longer sets the unsupported widen strategy. Its comment describes accepted strategies and the possible effect of the default auto strategy. A packaging test checks strategy values, and the changelog records the change.

Changes: Dependabot configuration

Layer / File(s) Summary
Correct and validate the pip strategy
.github/dependabot.yml, tests/test_packaging.py, CHANGELOG.md
The pip configuration removes widen and updates its explanatory comment. The test checks that each pip update omits the strategy or uses an accepted value, and confirms that a pip update exists. The changelog records the correction.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~7 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to 50578

The unsupported pip strategy has been removed to address Dependabot’s reported configuration rejection. The remaining issue is a small changelog detail that should be removed to meet the project’s user-facing requirement.
