WalkthroughIntroduced centralized worker launch validation and utilization enforcement via pulse-wrapper.sh, replacing ad-hoc CLI output checks. Added utility functions for worker state inspection and backfill cycle management, with updated documentation reflecting the new validation framework. Changes

the ripgrep (rg) dependency used in the loop that checks files (rg -q '...') by
either documenting rg in project setup/dependencies or replacing rg with a
portable grep -E/grep -q equivalent, and apply the same pgrep fix to other
occurrences of pgrep -fal in pulse-wrapper.sh so behavior remains consistent.

pgrep -fal has portability issues between Linux and macOS.
The -a flag has different meanings:
- Linux (GNU pgrep):
-a, --list-full— shows full command line - macOS (BSD pgrep):
-a— include process ancestors in match
Since output is discarded to /dev/null, only the exit code matters. The -l flag is also unnecessary here. For cross-platform reliability, use just -f:

Remove non-portable pgrep flags and document or replace rg dependency.
Line 1809 uses pgrep -fal, where -a and -l are GNU/Linux-only extensions not available on macOS. Replace with POSIX-compatible pgrep -f.
Additionally, rg (ripgrep) is used here without any documented setup requirement. While ripgrep is a project pattern, the absence of any dependency documentation creates maintenance friction. Either add ripgrep to an explicit setup/dependency file, or use grep -E as a portable fallback.

Code Review
This pull request introduces a robust mechanism to enforce worker utilization by backfilling pulse cycles. It adds several helper functions to count active workers, runnable candidates, and detect failed launches. The logic is sound and well-encapsulated. The documentation is also updated to guide users on the new check_worker_launch helper. I've identified a couple of areas for improvement in the new helper functions where the gh command's default pagination limits could lead to incomplete data, potentially affecting the accuracy of the backfill logic. I've updated the suggestions to use the --paginate flag for comprehensive data retrieval.

The gh CLI commands are limited to fetching 100 items by default. If a repository has more than 100 open issues or pull requests, this count of runnable candidates will be incomplete, potentially causing the backfill loop to terminate prematurely even when there is more work available. To ensure all items are retrieved, use the --paginate flag.

The gh issue list command is limited to fetching 100 items by default. If a repository has more than 100 issues with the status:queued label, this function will not count all of them, leading to an inaccurate queued_without_worker count. This could prevent the backfill logic from triggering correctly for failed worker launches. To ensure all queued issues are checked, use the --paginate flag.
