[Community] Establish QA staffing and ownership

Summary

Establish clear QA ownership for release qualification, community pull requests, regression triage, and supported-model coverage.

The project needs a documented operating model that makes qualification responsibilities, response expectations, and escalation paths predictable for maintainers and contributors.

Tasks

• Assign a primary QA owner and a backup.
• Define and maintain the supported platform, model, checkpoint, precision, and runtime-version test matrix.
• Identify which configurations are release-blocking, qualification-only, or best-effort.
• Establish a review and regression-triage rotation.
• Define response targets for new regressions, failing qualification jobs, and blocked pull requests.
• Document release sign-off responsibilities and the evidence required for approval.
• Define the escalation path when a regression cannot be reproduced or assigned promptly.
• Track gaps in automated model, platform, accuracy, performance, and reliability coverage.
• Create a recurring review of flaky, quarantined, skipped, and disabled tests.
• Require an owner, reason, and review date for every disabled or quarantined test.
• Document how changes to the supported test matrix are proposed, reviewed, and communicated.
• Publish the qualification process and ownership information where community contributors can find it.

Acceptance criteria

The project has:

• A named primary QA owner and backup.
• A documented qualification and release sign-off process.
• A maintained supported-platform and supported-model test matrix.
• Defined triage and response targets.
• A predictable escalation path for CI and release blockers.
• A recurring process for reviewing coverage gaps, flaky tests, and disabled tests.

Start with the issue's task list and acceptance criteria, then inspect the project's existing qualification, release, CI, and contributor documentation for any current ownership or test-matrix guidance. Done means the project has named QA owners, a documented sign-off and escalation process, maintained coverage and support matrices, response targets, and recurring review procedures.
