Analyze a Pull Request Value Stream

Run the deterministic read-only analyzer once for one pull request. Every invocation collects the complete observable retained lifetime. It writes a Perfetto-compatible trace, summary, and manifest under .nemoclaw-maintainer/pr-value-stream/pr-<number>/ and emits the summary as bounded JSON on stdout.

Do not run a reduced or latest-revision-only analysis. The latest-revision waterfall remains one derived part of the complete lifetime result.

Prerequisites

• Run from a NemoClaw checkout with authenticated gh access.
• Use Node.js 22.19 or later with type stripping enabled.
• Retained Vitest artifact timing is conditional: install this checkout's dependencies so node_modules/vitest/vitest.mjs is available, and install zipinfo and unzip. Optional artifact failures appear in caveats and do not become test-timing evidence.
