Summary

Promotes the verified dev branch to main for v0.4.2. This release adds friendly manifest failures, current-workspace update precedence, contributor branch guidance, and the finalized 0.4.2 metadata and public release notes.

Merge this PR with a merge commit. Do not squash it. The resulting promotion commit is the only commit eligible for the annotated v0.4.2 tag.

Tests

  • python -m pytest -q: 185 passed on integrated dev
  • Python 3.9 isolated suite: 185 passed; curriculum and installed-wheel smoke passed
  • Python 3.10 isolated suite: 185 passed; curriculum and installed-wheel smoke passed
  • pythonlings --root tests/fixtures/passing_curriculum verify: passing1 and passing2 passed
  • python -m mkdocs build --strict: passed
  • python -m build: built the 0.4.2 sdist and wheel
  • Installed 0.4.2 wheel: version, init, list, solution, reset, and all three patch-fix smokes passed

Screenshots

Not applicable. The release includes previously reviewed branding assets and CLI fixes; this PR only promotes the verified integration branch.

Checklist

  • Updated docs when behavior changed
  • Existing and added regression tests cover the release behavior
  • Verified python -m pytest -q
  • Promotion must use a merge commit

Post-Deploy Monitoring & Validation

  • Logs: watch the GitHub Actions publish workflow for ERROR, tag/version mismatch, build failure, and trusted-publishing failure messages.
  • Surfaces: verify the annotated tag object, GitHub Release asset list, PyPI 0.4.2 Files and provenance views, and a clean installation.
  • Healthy signals: v0.4.2, the GitHub Release, both PyPI artifacts, provenance, installed CLI version, and final dev/main ancestry all resolve to this promotion commit.
  • Failure trigger: stop if any tag, release, artifact, package version, or ancestry check disagrees. Do not move the tag or overwrite PyPI; publish corrections as v0.4.3.
  • Window and owner: the maintainer validates continuously from promotion merge through the successful clean-environment install and final dev fast-forward.

Review Change Stack

Warning

Review limit reached

@abhiksark, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 47 minutes

Limit details: You’ve used all 1 included review currently available under your plan.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The change adds strict manifest validation, safer workspace selection for update, protection against invalid update targets, and integration and unit coverage. It also updates version 0.4.2 metadata, release documentation, project status references, and the dev-based contribution workflow.

Changes

Workspace safety

Layer / File(s) Summary
Manifest validation and error handling
pythonlings/core/manifest.py, tests/unit/test_manifest.py, tests/integration/test_cli_verify.py
Manifest loading now converts file and parsing failures into ManifestError and validates fields, paths, symlinks, and regular files. Tests cover these failures and traceback-free CLI errors.
Update target resolution and synchronization
pythonlings/cli.py, pythonlings/core/curriculum.py, tests/integration/test_cli_workspace.py
update resolves explicit, global, current, or home workspace paths without creating invalid targets. Curriculum updates reject source directories and invalid workspace structures. Tests verify precedence and non-modification behavior.

Release and contribution refresh

Layer / File(s) Summary
Release metadata and project documentation
pyproject.toml, CHANGELOG.md, Readme.md, RELEASE.md, docs-site/*
The project version is 0.4.2. Release references use generic or latest-release wording. Documentation points contributors to active issues.
Branching and release workflow
AGENTS.md, CONTRIBUTING.md
Contribution guidance now uses dev as the integration branch and defines promotion from verified dev to main before tagging releases.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to b7933

The release promotion is backed by passing test, build, documentation, and installed-package checks, but release documentation still gives stale tag instructions that could lead to an incorrectly formatted or mismatched v0.4.2 release. Align that process documentation before merging; the remaining issues are localized follow-ups.

Poem

A rabbit checks each path with care,
And keeps unsafe links from hopping there.
The workspace finds its proper place,
While release notes refresh their face.
Dev branches merge, then tags take flight.

- Around line 51-59: Update the release documentation’s tag format from v0.1 to
vMAJOR.MINOR.PATCH, consistent with pyproject.toml’s current version v0.4.2 and
the publishing workflow. After the verified dev-to-main merge commit is
promoted, create the v0.4.2 tag on that exact commit.

In `@docs-site/index.md`:
- Around line 2-5: Move the “docs-site/index.md” heading below the closing YAML
front matter delimiter so it renders as the page title; if it is only a file

Add the required future import.

Not changing this. The current CLAUDE.md delegates Python policy to AGENTS.md, and neither guide requires from __future__ import annotations. Existing neighboring test modules such as tests/integration/test_cli_verify.py and tests/unit/test_manifest.py also omit it, so adding it only here would create an unsupported one-file convention.
