The refresh now preserves public/owner scope, keeps generated intent-label ownership aligned, is idempotent, and rejects foreign-owner documents. Three scoped P2 review items were also resolved: answer-owner ref mutation moved out of render, PDF page changes use router navigation without scroll reset, and the worker-free staging harness no longer enqueues a reindex job before cleanup. No other high-confidence issue remained in the reviewed follow-up diff. | GitHub review-thread inspection; bundled Next.js navigation guide; focused Vitest 38/38; scoped ESLint; Prettier; full TypeScript; `git diff --check`.

The unsupported-related-document deadline finding was not applicable because the configured unsupported route budget is intentionally `0` and creates no deadline. | GitHub review-thread inspection; focused Vitest 58/58; scoped ESLint; Prettier; full TypeScript; `git diff --check`.

Agitation dose/route retrieval now keeps only the dose and route signals present in the question; the exact case retrieves its expected source and five citations in 1.54 seconds without a model.
