Move Time Block

A time block as seen by the cursor sync feed.

matter_segment is a denormalized snapshot of the segment + matter info at the time the row was returned. The desktop client renders directly from this; segment/matter renames take effect for a row only when the row's own version advances. Accepted as the rename-staleness compromise of the denormalized design.

version is the trigger-bumped global cursor counter (BIGINT). Local mirror's apply predicate compares it as the freshness signal (WHERE excluded.version > target.version). updated_at is informational only.

artifacts is projected from the internal time_blocks.facts fact sheet by dto_builders.block_artifacts_dto — BlockFacts itself is deliberately NOT on the wire, so it stays refactorable. Only artifacts is projected today; sub_app / action / counterparties / has_external have no client consumer, and per this module's contract we ship only what the client consumes. Adding one later is a DTO line plus a mapper line — the client stores the blob opaquely, so no migration is involved.
