Code Review
This pull request correctly fixes a regression from the t1031 modularization by restoring the ALL_STATUS_LABELS constant, which resolves an unbound variable error. The fix is straightforward and necessary. I've kept the suggestion to improve the maintainability of the new constant by defining it as a bash array instead of a comma-separated string, as it aligns with general shell scripting best practices and repository style guidelines, and is not contradicted by any specific rules.

For better maintainability and robustness, it's recommended to define this list of labels as a bash array instead of a comma-separated string. Using an array avoids the need for string splitting (e.g., with tr or by changing IFS) and allows for safer iteration over the elements, preventing potential issues with word splitting or globbing.
The repository style guide also encourages the use of arrays for dynamic command construction, and this principle extends well to managing lists of values.
| ALL_STATUS_LABELS="status:available,status:queued,status:claimed,status:in-review,status:blocked,status:verify-failed,status:done" | |
| ALL_STATUS_LABELS=("status:available" "status:queued" "status:claimed" "status:in-review" "status:blocked" "status:verify-failed" "status:done") |
References
- The style guide recommends using bash arrays for dynamic command construction, which implies a preference for arrays over delimited strings for managing lists of items to avoid issues like word splitting and make iteration safer. (link)
…(t1035) The ALL_STATUS_LABELS constant was defined in the monolithic supervisor-helper.sh but dropped when code was split into issue-sync.sh module. Under set -euo pipefail, the unbound variable crashed sync_issue_status_label(), which blocked cmd_dispatch() from completing (dispatch hung during the cmd_transition -> sync_issue_status_label call chain). This was the root cause of workers never starting after t1031 merged — the dispatch function wrote metadata to the log but crashed before creating the dispatch script and launching the worker process.
