contributor-pipeline-gardening

Maintenance of the contributor issue pipeline for JSONbored/metagraphed — closing issues that are already done but not marked so, and keeping the contributor-available backlog at its 50-100+ steady-state floor with well-scoped new issues. Runs every ~8h via the scheduled task (raised from daily on 2026-07-15 so the floor is maintained continuously, not caught up once a day). Invoke for "run the issue gardening", "audit open issues for stale/complete ones", "generate new contributor issues", or any recurring/scheduled run of this process. reference.md (next to this file) has the exhaustive label/milestone/template detail — read it before doing real work, not just this file. This is the metagraphed-specific instance; JSONbored/gittensory (loopover) has its own separate copy with different conventions — do not cross-apply either repo's specifics to the other without being asked.
