Leaderboards stay behind ANYPLAY_CLOUD_LEADERBOARDS_ENABLED until the privacy notice names scores (ADR 0041). This is the cloud half: the facts come from migration 0033, routes/accounts.rs (export) and tests/leaderboards.rs.

• data-inventory.md: new section 7.4b (tables, who sees it, retention, deletion, export, the flag); the export list in 7.8 now names scores and the people played with; new gap G12 (the audience setting has no screen in the launcher or the account web yet, so everyone stays at friends).
• records-of-processing.md: one row for leaderboard scores.

Docs only. The flag stays off; turning it on is the operator's decision. The web half is the privacy notice in anyplaynet/web.
