Codex/node network devtools v2

[GrinZero]

Summary

• Delivers the v2 Native/Legacy backend architecture, standard CDP discovery,
  zero-code CLI setup, capability-aware fallback, official DevTools support,
  Session/HAR/Replay/Trace, and Legacy-only request mocking.
• Adds a reviewable manual acceptance layer: 14/14 cases passed, with 26
  privacy-reviewed screenshots, 17 structured artifacts, five reproduction
  harnesses, and a 51-file SHA-256 manifest.
• Fixes an HTTP/2 capability overclaim found during the manual run. The exact
  package completes the HTTP/2 lifecycle on Node 22.22.3; Node 24.16/26.8
  reproduce an upstream Inspector crash, so those and unverified future majors
  now correctly advertise http2=false.

  449d47db89109e826eb0e7e0584777365eac3f9b
• Exact package: node-network-devtools@2.0.0, 190 files
• Tarball SHA-256:
  e97dc360d2fcd5d141b13bca490f603b802dc7fe94f3b6a06a690c7a7f48e2ac
• Local automated gate: 60 files / 841 tests passed
• Repository build and lint passed
• Evidence checksum: 51/51 files verified
• Remote quality gates:
  pull-request run 33154271318
  and
  push run 33154267596
  both passed, including packed consumers, Native/Legacy protocol E2E,
  Windows/macOS 20-round smoke, and the official Chromium frontend
• Manual runtime: Node 24.16.0 on macOS arm64
• Compatibility probe: Node 22.22.3, 24.16.0, and 26.8.1
• Browser: Chrome for Testing 151.0.7922.34, driven by Playwright

The manual run used only loopback traffic and an isolated consumer installed
from the exact tarball. Local filesystem prefixes were redacted; protocol
methods, bodies, statuses, event counts, and lifecycle semantics were retained.
