• Documentation
• Internal (build, CI, dependencies, tooling)

Packages touched

• shared (types and contracts)
• core (framework-agnostic capture/reporting)
• service (WebdriverIO adapter)
• nightwatch-devtools (Nightwatch adapter)
• selenium-devtools (Selenium adapter)
• backend (server)

Greptile Summary

The PR expands component and adapter test automation while updating trace capture, run-state continuity, trace parsing, and related app behavior.

• Adds WebdriverIO browser-based UI coverage across explorer, workbench, player, panel, and tab components.
• Adds cross-adapter trace configuration and capture support for WebdriverIO, Selenium, and Nightwatch/Cucumber examples.
• Propagates stable run identifiers through worker connections so backend state can continue across workers.
• Consolidates trace archive paths and improves trace reading, writing, command selection, error rendering, and compare-step resolution.
• Removes the previous fixture-driven capture-parity verification layer and documents the replacement testing strategy.

Confidence Score: 5/5

The PR appears safe to merge because no blocking failure remains within the scope of the prior review thread.

The previously reported missing-fixture skip path no longer exists: the capture-parity suite, ready matrix, fixtures, verification script, and associated CI workflow were removed together, so the old silent-skip behavior cannot occur on the current HEAD.

Important Files Changed

Filename	Overview
packages/core/src/run-id.ts	Introduces shared environment-backed run identity generation and propagation.
packages/backend/src/index.ts	Updates worker connection handling to preserve backend state across sockets belonging to the same run.
packages/backend/src/trace-reader.ts	Extends trace archive parsing around the consolidated trace-file contract.
packages/app/src/components/workbench/compare/stepResolution.ts	Resolves preserved test UIDs directly so compare commands are windowed to the selected test.
packages/nightwatch-devtools/src/cucumber-lifecycle.ts	Adds pre-quit Cucumber capture handling while the scenario browser session remains available.
packages/app/wdio.conf.ts	Configures the new WebdriverIO browser-component test suite.
