 None of these block convergence — every device agrees on the same answer. They are about the answer being the one a person expected. Ranked by how much they will actually bite.
 
 1. **`block.outdented` moves blocks it does not name.** Trailing siblings become children, so its effect is defined over whoever the siblings happened to be at fold time, which differs per device. Carrying the explicit ids it moves makes it mergeable. Payload `v: 3` — `v: 2` is the one that dropped `page`. **Do this one before relying on sync daily.**
-2. **`block.deleted` has no tombstone.** Device A deletes X while device B writes a block `after: X`. The fallback in `reduce` (`packages/pages/blocks.ts`) keeps the content — the right instinct — but the block lands at the bottom of the page instead of where it was written. A tombstone restores the placement.

 3. **`block.indented` no-ops when its `parent` is gone**, silently dropping the user's intent. Deterministic, so both devices drop it identically. Still surprising.
 4. **Text is last-writer-wins per block.** Concurrent edits to one block lose one side. The loser is still on disk forever, so it can be surfaced rather than pretended away.

 ## Tests
 
-The ledger's tests cover the order, the stalls and convergence, with events of their own that are not blocks. The block fold is tested without a log in `packages/pages/blocks.test.ts` and `packages/pages/pages.test.ts`, and through one in `src/main/features/projects/pages/pages-store/pages-store.test.ts`. Both write from a single device. Nothing yet tests two devices' block events interleaving, so each deferred item above lands with a test that folds its events in both orders.
