Three executable research slices connected the minimal function language to crash recovery, external effects, and a more precise model of logical continuity.
Ordinary functions lowered to durable runs
Typed functions compiled to durable continuations and state deltas. After crashes, they resumed without replaying committed code or admitting stale activations. See the durable-runtime results.
External effects became durable protocols
Effects commit intent before dispatch and receipt before resumption. Deduplicated calls retry one
identity; uncertain calls run at most once and may return Unknown. Read the
[external-effect results][external-effect-results].
Runs became replaceable machinery, not source values
An application became a graph of typed causal continuities: stable subjects with replaceable runs and activations. Once results, maintained values, and occurrences retain distinct contracts.
Lifetime requires more than demand
Interest, rooted retention, obligation, and attachment follow different lifetime laws. Reclamation requires causal reachability plus obligations; disconnecting a socket does not end an attachment. See the causal-continuity results.
