artifact-prune.yml

# Weekly artifact-prune job (Phase 0 retention policy, artifact-gc task).
# Deletes perf-capture dirs older than 30 days that are not cited in docs. See
# scripts/artifact-prune.ts for rules. (There is no perf-baselines.json pin to
# honor — that file was permanently removed 2026-06-02; the script's "pinned in
# perf-baselines.json" clause is now an `if present` no-op. Perf is
# raw-metrics / non-gating until STABILIZAT-1 re-establishes a baseline. —
