Compatibility verification workflow.

Use this workflow to keep product matrices tied to tests, fixtures, references, release notes, evidence records, owner review, and visible stale-row warnings.

Review Workflow

Collect Change Signals

Check product source changes, tests, fixtures, generated references, release notes, evidence indexes, and known-limits pages for rows that need review.

Refresh Evidence

Update evidence IDs, fixture names, release-note references, or owner signoff before changing any row status or maturity.

Review Row Wording

Product SME reviews runtime truth; docs QA checks notes, unsupported behavior, stale dates, evidence, and copy/paste safety.

Update The Matrix

Change the rendered matrix, evidence index, known-limits links, and internal tracking records in the same PR when behavior changes.

Record The Date

Set `last_reviewed` only after required reviewers accept the row for the stated scope.

Stale Warning Rules

The matrix component derives each row's next due date from lastReviewed plus the page cadence. Rows show Current until the warning window opens, Due Soon during the warning window, and Stale after the due date passes or the review date cannot be parsed.

A stale row should stay visible, but its wording must not be promoted to stronger support, security, durability, performance, scale, compliance, or customer-commitment language until the owner refreshes evidence and required reviewers accept the row again.

Review Boundary

Compatibility review records are maintained internally. Public matrices should expose owner, reviewer, cadence, evidence ID, and review status without publishing private source locations.
