Metadata

Branch: chore/ci-execution-time-parallel-nox-sessions
Commit Message: chore(ci): split test suites into parallelizable nox sessions
Milestone: v3.8.0
Parent Epic: #1678

Background and Context

The current CI pipeline runs all tests in a single monolithic nox session, which means the total CI wall-clock time is bounded by the slowest test suite. Splitting the test suites into smaller, logically grouped nox sessions that can be executed in parallel by the CI workflow will reduce overall CI execution time and provide faster feedback to contributors.

This issue is a child of Epic #1678 (CI Execution Time Optimization — Timeouts, Concurrency, and Coverage Artifact Sharing), which tracks all structural improvements to the CI pipeline.

Expected Behavior

Test suites are split into smaller, logically grouped nox sessions (e.g., by feature area or by speed tier). The .forgejo/workflows/ci.yml workflow is updated to run these sessions in parallel CI jobs. Coverage reporting remains accurate and the overall CI execution time is reduced.

Acceptance Criteria

noxfile.py defines multiple focused test sessions that can be run independently.
.forgejo/workflows/ci.yml runs the new nox sessions as parallel jobs.
Coverage data from all parallel sessions is merged and reported correctly.
No test scenarios are lost or duplicated in the split.
All nox stages pass after the change.
Coverage remains ≥ 97%.

Supporting Information

Parent Epic: #1678 — CI Execution Time Optimization
Related: .forgejo/workflows/ci.yml, noxfile.py

Subtasks

Analyze the test suites to identify logical splitting points (e.g., by feature area, by speed tier).
Create new nox sessions in noxfile.py for the split test suites.
Update .forgejo/workflows/ci.yml to run the new nox sessions as parallel jobs.
Ensure coverage data from all parallel sessions is merged and reported correctly.
Update features/ci_workflow_validation.feature to assert the new parallel test job structure.
Run nox (all default sessions) and fix any errors.
Verify coverage ≥ 97% via nox -s coverage_report.

Definition of Done

This issue is complete when:

All subtasks above are completed and checked off.
A Git commit is created where the first line of the commit message matches the Commit Message in Metadata exactly (chore(ci): split test suites into parallelizable nox sessions), followed by a blank line, then additional lines providing relevant implementation details.
The commit is pushed to the remote on the branch matching the Branch in Metadata exactly (chore/ci-execution-time-parallel-nox-sessions).
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%
