Convex Retention

Overview

ClawHub retention is code-owned. Every current Convex table must be classified in convex/lib/retentionPolicy.ts, and ephemeral tables need an indexed, bounded cleanup path unless their lifecycle is handled by usage-time validation or a documented component.

Checklist

• Use clawhub-convex and read convex/_generated/ai/guidelines.md first.
• Add every new schema table to RETENTION_POLICIES; the Record<TableNames, RetentionPolicy> type is the enforcement gate.
• For ephemeral tables, prefer an explicit expiration field plus index, then prune with .withIndex() and .take(...).
• For new generic TTL tables, prefer expirationTime to match Convex Auth. Keep existing expiresAt, dayStart, and processedAt fields unless that table already needs a real migration.
• Use RETENTION_STANDARD_BATCH_SIZE for ordinary retention jobs. Keep incident-tested special cases, such as skillStatEvents, on their documented caps.
• Cron jobs should schedule bounded cleanup entrypoints only. Large one-off production migrations or destructive backfills still start with convex-migration-helper.
• Do not bulk-clear active auth state. Expired authSessions and authRefreshTokens are pruned by convex/retention.ts.

Verification

• Add or update focused tests for policy classification and cleanup behavior.
• Run the focused Vitest slice for touched cleanup modules.
• Run bunx convex codegen after schema/API changes.
• Run a real Convex runtime check such as bunx convex dev --once --typecheck=disable.
