A self-describing Value node (null/int/fixed/bool/str/list/object) with constructors, builders (Value.add/put) and accessors (get/at/count/kind/ as_int/as_str/…). Reflect.serialize(entity) walks an entity's whole component set into a value tree — one member per component, each a sub-object of its fields — and Reflect.apply(entity, value) writes one back; a fixed field becomes a fixed node, everything else an int node, so the round-trip is bit-exact, with the model id under "@kind". Json.encode/parse bridge the tree to and from compact, stable, diffable text, with fixed written as an exact terminating decimal that parses back bit-for-bit (verified across the raw Q16.16 range). Together: a one-call, bit-exact save/load for entities. Written in Ludic and spliced on demand (runtime/native/value.ludic + reflect_io.ludic, like Query/Light), so a program that doesn't touch Value.*/Json.*/Reflect.serialize compiles byte-identically and the C-free bootstrap fixpoint holds (verified). The general tagged-union/any language type stays tracked in #1; this ships the concrete value tree the serializer needs. Adds 21 namespace-method docs pages + Value/Json sections, examples/library/serialize.ludic, and a regression case. Whole CI set green: x test 72/72, x test-tools 30/30, check-impl/vocabulary/docs.

The inverse of <a href="reflect-serialize"><code>Reflect.serialize</code></a>: writes the fields of a value-tree <code>value</code> back into a live <code>entity</code>, and returns how many were set. Only components the entity already has and fields the schema knows are applied; reserved <code>"@"</code>-keys (like <code>"@kind"</code>) and unknown names are skipped, so a partial or older save loads cleanly. Feed it the output of <a href="json-parse"><code>Json.parse</code></a> to load a save.
