Metadata

  • Branch: chore/ci-parallelize-nox-sessions
  • Commit Message: chore(ci): parallelize default nox sessions to reduce CI execution time
  • Milestone: v3.2.0
  • Parent Epic: #1678

Background and Context

The default nox sessions are currently run sequentially in the CI pipeline. Many of these sessions — such as lint, typecheck, and security_scan — are fully independent of one another and do not share mutable state. Running them sequentially wastes wall-clock time and increases the overall CI execution time unnecessarily.

Expected Behavior

Independent default nox sessions should be executed in parallel in the CI pipeline, reducing the total CI execution time while still correctly aggregating all results.

Acceptance Criteria

  • The CI pipeline runs independent default nox sessions (e.g., lint, typecheck, security_scan) in parallel.
  • The CI pipeline correctly aggregates the results of all parallel sessions (i.e., a failure in any session still fails the overall pipeline).
  • The CI execution time is demonstrably reduced compared to the sequential baseline.

Subtasks

  • Investigate using nox --parallel or a suitable CI-level parallelism mechanism to run default sessions concurrently.
  • Identify which default nox sessions are safe to run in parallel (no shared mutable state or conflicting resources).
  • Modify the CI workflow to execute the identified independent nox sessions in parallel.
  • Ensure the CI pipeline correctly aggregates results from all parallel sessions (any failure = pipeline failure).
  • Measure and document the reduction in CI execution time.
  • Run nox (all default sessions) locally, fix any errors introduced.
  • Verify coverage >= 97% via nox -s coverage_report.

Definition of Done

  • All subtasks above are completed and checked off.
  • The default nox sessions run in parallel in the CI pipeline.
  • The CI execution time is demonstrably reduced.
  • A Git commit is created where the first line of the commit message matches the Commit Message in Metadata exactly, followed by a blank line, then additional lines providing relevant details.
  • The commit is pushed to the remote on the branch matching the Branch in Metadata exactly.
  • The commit is submitted as a pull request to master, reviewed, and merged before this issue is marked done.
  • All nox stages pass
  • Coverage >= 97%
