Walkthroughs

Description

• Archive the sandbox workspace and remove its code from the repo.
• Drop sandbox references from CODEOWNERS, labelers, Renovate, and Codecov.
• Record the archive in the repo’s archived plugin/workspace registries.

High-Level Assessment

The following are alternative approaches to this PR:

1. Keep workspace in-tree but mark as archived/readonly

• ➕ Preserves source for grepping/blame without using tags
• ➕ Avoids breaking downstream forks that referenced paths directly
• ➖ Continues to burden repo tooling (Renovate/Codecov/labeling) and reviewers
• ➖ Increases risk of accidental dependency drift or build breakage

2. Move sandbox to a dedicated archive folder/repo

• ➕ Keeps mainline lean while preserving code in an explicit location
• ➕ Clear separation of maintained vs archived content
• ➖ Requires extra repo/release/process decisions and tooling updates
• ➖ Still needs ongoing CI/ownership decisions if kept in the same monorepo

Recommendation: Current approach (remove workspace from mainline and record the archive in central registries) is the best fit for an unmaintained workspace. It minimizes ongoing tooling/CI overhead while preserving traceability via git tags/links and explicit archived listings.
