# Rechenaufwand-Score: R=2 (K=2, L=2, N=2) | last-calibrated: 2026-08-25
# Trigger policy: repo framework score calibration for workflow cost controls.
# Consolidated community automation: greeting, labeling, issue summarization.
# Replaces: greetings.yml, label.yml, summary.yml
#
# Security hardening: all third-party actions are pinned to immutable commit
# SHAs (OSSF Scorecard Token-Permissions + Pinned-Dependencies compliance).
# SHA pins verified 2026-08-11 — re-verify on dependency updates.
