v0.29.0

• ExecutionMode.Local removed. Replaced by ExecutionMode.LocalQuery — read-only client-side compute over locally replicated state, no RPC. Pre-0.29.0 Local permitted client-only writes which is a divergence anti-pattern (server never confirms; two clients diverge forever). UI-state mutations belong in a ViewModel / POCO outside SharedMeta.
• LocalQuery contract (enforced where possible by the generator): must return a value (no void / bare Task); must not mutate State, call cross-entity services, or consume Context.Random; requires the entity to be subscribed at call time.
• Pair with Query (server-roundtrip read for entities NOT subscribed). Use LocalQuery for cheap per-method reads over your own / any subscribed entity's state; use Query when authoritative source is on the server.
