SUMMARY

A fresh source install can select an older published apache-superset-core with incompatible SQLAlchemy requirements, and the CLI imports rich even though package metadata does not declare it. Declare rich directly and document installing the application and core together from the same checkout, including the editable development command.

Refs #45937 and #42568. This addresses the Superset packaging portion of #45937; it does not close the broader Flight SQL compatibility report. Table/type reflection fixes belong to the third-party adapter and are being submitted separately. The rich declaration also overlaps the broader, still-open Python 3.15 work in #45823; this PR offers the small independently validated packaging fix.

No core version bound is invented before a matching package is published. The source-install command uses the matching local core without bypassing dependency resolution.

Not applicable; dependency metadata and documentation only.

TESTING INSTRUCTIONS

Validated on Python 3.12.16, macOS arm64, against master 7519fa8b6f5a145097d51e36579240e872044266:

• Fresh virtual environment: python -m pip install /path/to/superset /path/to/superset/superset-core (plus pytest, pre-commit and build as validation tools). rich==15.0.0 was installed through application metadata, without an explicit rich install.
• python -m pip check: no broken requirements.
• Installed package metadata declares rich; superset --help succeeds with disposable local configuration.
• superset db upgrade against a fresh isolated SQLite metadata database succeeds.
• Application creation and /health: HTTP 200.
• pre-commit run on all three staged files: all applicable checks passed.
• git diff --check: passed.

Reproduce with a clean Python 3.12 environment, the documented source-install command, and a disposable Superset configuration. No existing metadata or running deployment needs changing.

Separately, the adapter fix was exercised with Superset 7.0.0rc2 against a disposable Redis Arrow Flight SQL endpoint: table discovery, BIGINT/VARCHAR/FLOAT column reflection, ordered/NULL/empty reads, SQL Lab CREATE/INSERT/UPDATE/DELETE/DROP with read-back assertions, dataset creation, and a grouped chart data query passed. Browser rendering and production behavior remain unverified.

Fixed the Netlify build failure in commit 9520dce: the source-installation link now uses /developer-docs/contributing/development-setup#flask-server to cross the admin/developer Docusaurus sections. Verified the target page and Flask-server anchor, and verified the committed diff changes exactly that link. The replacement Netlify deploy preview is successful: https://deploy-preview-45938--superset-docs-preview.netlify.app . No new local pre-commit or full docs build was run; validation here is the exact change and hosted preview build.
