"""XEngine coverage: release-post drafting + mentions poll, held/deduped/capped.

Mirrors the release-manager engine tests: flag-gated, no-creds no-ops, drafts
via the local model (mocked here), enforces the 280-char limit, dedupes
mentions by id, and caps origination per cycle + rolling open count. Never
posts — asserted against a real Postgres DB.
