**retain_closets.py** — 90-day closet aging enforcement for #1083.
Removes *.closet.json files older than --days (default 90) from the
fleet palace. Supports --dry-run for safe preview. Wired into the
weekly-audit workflow as a dry-run CI step; production cron guidance
added to workflow comments.
**tunnel_sync.py** — remote wizard wing pull client for #1078.
Connects to a peer's fleet_api.py HTTP endpoint, discovers wings via
/wings, and pulls core rooms via /search into local *.closet.json
files. Zero new dependencies (stdlib urllib only). Supports --dry-run.
This is the code side of the inter-wizard tunnel; infrastructure
(second wizard VPS + fleet_api.py running) still required.
**Tests:** 29 new tests, all passing. Total suite: 294 passing.
