A skill nobody has loaded in a month is prompt weight, not knowledge, and archival is recoverable (`hermes curator restore`). Defaults move stale 30→14 / archive 90→30; config v44 rewrites only the OLD defaults so an explicitly customized window is preserved. `hermes curator prune` now defaults --days to curator.archive_after_days instead of a hardcoded 90 so the manual and automatic paths agree.
