​Created by Roomote. Follow up by mentioning @roomote, in the web UI, or in Discord.

What changed

  • Keep the existing cache-compatible package and core coverage task identities on both platforms.
  • Run the five expensive extension ownership lanes on Windows without V8 coverage instrumentation, using cacheable Turbo tasks with the same inputs as their coverage counterparts.
  • Keep Ubuntu as the authoritative extension coverage producer, verifier, merger, and uploader.
  • Add required workflow contract tests for matrix conditions and matching cache boundaries.

Why this change was made

Recent Windows runs took 6:00 with one extension coverage lane cached and 8:10 when all five lanes missed Turbo cache. The first implementation changed every Windows task identity; although the cache archive restored successfully, Turbo missed those new tasks and the hosted job spent 6:23 in package tests plus 8:18 in a monolithic extension suite. This revision preserves proven cache hits and isolates the optimization to sharded extension tasks.

Impact

Windows retains the full test scope and authoritative Ubuntu coverage remains unchanged. Locally, the five new extension tasks complete cold in 1:15 and then hit Turbo cache in 0.6 seconds; the updated hosted Windows result remains the authoritative measure for the sub-five-minute target.

📝 Summary

Summary by CodeRabbit

  • Tests

    • Added automated validation for the code-quality workflow.
    • Expanded checks for coverage collection, verification, merging, and uploads in coverage-enabled environments.
    • Added validation that standard test suites run correctly without coverage collection.
    • Added dedicated test commands for API, core, services, miscellaneous, and tree-sitter areas.
  • Chores

    • Improved continuous integration reliability through automated workflow and test configuration checks.

Walkthrough

The Code QA workflow now collects coverage on Ubuntu and runs plain tests on Windows. Coverage verification, merging, caching, and uploads run only for coverage-enabled lanes. New scripts, Turbo tasks, and CI assertions support and validate this behavior.

Changes

Code QA coverage flow

Layer / File(s) Summary
Coverage matrix and conditional test lanes
.github/workflows/code-qa.yml
The matrix uses collect-coverage. Ubuntu runs coverage lanes. Windows runs plain test lanes. Coverage verification, merging, caching, and uploads require matrix.collect-coverage.
Plain test lane configuration
src/package.json, src/turbo.json
Five non-coverage Vitest scripts and matching Turbo tasks were added for API, core, services, misc, and tree-sitter tests.
Workflow configuration assertions
scripts/code-qa-workflow.test.mjs
The Node test checks workflow commands, matrix values, coverage-step conditions, and matching Turbo task inputs and dependencies.
CI validation wiring
package.json, .github/workflows/code-qa.yml
The test:code-qa-ci script runs the workflow test. The compile job invokes the script.

A future workflow edit could misroute Windows coverage or plain test lanes without CI detecting it. Strengthen the workflow assertion before merging.

Updated in 7a88e978d.

  • Fixed the valid condition-binding finding and resolved its thread.
  • Preserved cache-compatible package/core task identities; prior Windows evidence shows 5/5 package coverage tasks hit in 0.176s and core coverage tasks hit in under 0.1s each.
  • Added five sharded, cacheable plain extension tasks with contract-tested inputs matching their coverage counterparts. Local cold/warm execution was 1:15 / 0.6s.
  • Full tests (8,454 passed, 39 skipped), lint, types, coverage-cache contract, focused workflow tests, formatting, and diff checks pass.
  • The Description warning is not actionable: this repository has no checked-in PR template and the PR has no approved linked issue to invent or close. The refreshed description follows the repository’s actual PR contract and includes the measured evidence.
  • The updated hosted Windows job is currently in the extension lane step; setup plus cache restore took 2:13 and the cache-compatible package step took 2s. Final sub-five status is still pending that job.

Visual proof was not produced because the proof step exceeded its shared deadline; this workflow-only change is supported by CI and contract-test evidence instead.

Parse workflow steps before asserting their guards. workflowStep captures raw indented YAML text, and the assertions for Run extension coverage lanes and Run extension test lanes search that text with assert.match and includes. A comment or nested value can preserve the expected condition string after the step-level if field is removed or changed. The test can then miss Windows coverage running with collect-coverage: false or the plain lane using the wrong condition. Parse each step and assert its run and if fields together.
