Acceptance Criteria

  • Testing doc states single-process local default, parallel CI
  • Note orphaned test procs deadlock; agent-worktree clears them

Expected Test Plan

No expected checks recorded.

Checks Run

No completed checks recorded.

Agent Context

Doc sweep from the task-card session wrap. docs/agents/modules/testing.md (~L75-78) still says the suite parallelizes by forking and to run PARALLEL_WORKERS=1 manually if it crashes. PR #169 made test_helper.rb default to single-process LOCALLY (TestParallelism.worker_count: parallel only when CI set, PARALLEL_WORKERS overrides) + bin/agent-worktree test clears orphaned 'rails test' procs first. Update the paragraph to match: single-process is now the local default (plain bin/rails test is reliable), CI keeps parallel, orphaned procs deadlock the next run / agent-worktree clears them / don't pipe through tail. Docs-only, kind=docs exempt from the test-tier gate.

Stage Timeline

Who handled each stage, the time it took (measured), and the model / tokens / cost reported (best-effort) — plus who's on it right now. — means the agent didn't report that metric.

QA review feedback, agent handoffs, and follow-up notes for this task.

Comment 1 day ago

Review pair APPROVED: carl (heavy) + shannon (light). Both verified the doc against live code — TestParallelism.worker_count (test_helper.rb: 1 locally, :number_of_processors on CI, PARALLEL_WORKERS overrides) and bin/agent-worktree clear_orphan_test_procs (cwd-scoped). pg fork-safety claim accurate; obsolete OBJC_DISABLE_INITIALIZE_FORK_SAFETY dropped. CI green (4/4).
