v0.3.0

Added

• Typed mutations (ADR-0010). SyncRegistry takes a third generic — a collection-row manifest — so handlers are fully typed without casts: new SyncRegistry<TUser, Env, { messages: Message }>() types pk (must be a column) and each handler's op.cols per op (insert→Message, update→Partial<Message>, delete→none). Purely type-level; the untyped two-generic form still works (op.cols falls back to unknown).
• Changelog time-based retention (ADR-0009). A new changelogRetentionMs knob (default 2 days) prunes _sync_changes rows older than the window, so the log is bounded by age, not just key-cardinality. A client reconnecting from beyond the surviving floor now receives a reset + full snapshot instead of an incremental delta. Set changelogRetentionMs: null to disable retention (compaction-only, the prior behavior).

Changed

• Renamed Registry → SyncRegistry. Breaking, no compat shim. The old name was too generic and clashy; the public surface is uniformly Sync* (SyncDurableObject, runSyncedWrite, registerSync). Update your import and new SyncRegistry(...).
• registerSync now reconciles CDC triggers to the registry instead of only adding them: triggers for a collection you've removed from the registry are dropped on the next registerSync, so an orphaned table stops firing capture triggers into _sync_changes. Trigger reap only — existing change rows are left untouched. (ADR-0008)
