Compact archive controls are documented in the full reference: PROJECT_DATA_ARCHIVE_COMPACT_ENABLED, PROJECT_DATA_ARCHIVE_DAILY_WRITE_BUDGET, PROJECT_DATA_ARCHIVE_WRITE_ESTIMATE_FACTOR , PROJECT_DATA_ARCHIVE_R2_TIMEOUT_MS, PROJECT_DATA_ARCHIVE_BUDGET_RECEIPT_RETENTION_MS and PROJECT_DATA_ARCHIVE_BUDGET_RECEIPT_CLEANUP_LIMIT. The daily allowance is an admission estimate; preserve normal-account headroom and use measured SQL counters when tuning it.
