⚡ Bolt: Concurrent PR status check#66
Conversation
* 💡 **What:** Use `concurrent.futures.ThreadPoolExecutor` to check PR states concurrently in `_filter_to_still_open_prs`. * 🎯 **Why:** Sequential subprocess calls to the GitHub CLI (`gh`) for each PR create a significant N+1 network bottleneck when the fan-out supervisor initially filters the list of PRs. * 📊 **Impact:** Reduces startup latency linearly with the number of open PRs (up to `max_workers=10`). * 🔬 **Measurement:** Compare the execution time of the initial fan-out loop filtering when there are many open PRs before and after this change.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

The S606 hint is a non-issue (intentional shell-less re-exec). RUF005 is purely stylistic.

In @.jules/bolt.md:
- Line 1: The changelog entry header uses the wrong year; update the header
string "## 2024-05-30 - Concurrent PR status checking" in .jules/bolt.md to the
correct date "## 2026-05-30 - Concurrent PR status checking" so the entry is
chronologically accurate.

547-576: ⚡ Quick winThread-safety:
_pr_is_still_openlooks pure; confirm_run_commandshared state
The concurrency/filtering logic is sound:executor.map(...)feeds results in input order and_print_step(...)is only called in the consuming loop (main thread), not inside workers. Inralph_loop/gh_ops.py,_pr_is_still_open/_pr_viewjust call_gh_json/_pr_viewand inspect returned fields—no module-level mutation there. The remaining risk is whetherralph_loop/process.py’s_run_command/_remaining_command_timeoutmutate any module-level globals during execution (e.g., deadline/log configuration), and that such configuration happens before theThreadPoolExecutorblock.

Fix the entry date (year is off by two).
This learnings entry is dated 2024-05-30, but the change is being introduced on 2026-05-30. In a chronological log this misdates the entry by two years.
