feat(reflect): generic value tree + Reflect.serialize/apply + JSON bridge (#44)
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.

Changesets

A changeset is one small Markdown file describing a single user-facing change, dropped in this directory. x release consumes every changeset here into a new CHANGELOG.md section, bumps VERSION, and deletes the consumed files.

Format

bump: minor
type: feat
One or more lines describing the change, in the past-agnostic imperative used in
the changelog. Markdown is fine.
  • bump: — major, minor, or patch (SemVer). The release version is bumped by the highest level among the pending changesets (unless x release <level> overrides it).
  • type: — the Conventional Commit type (feat, fix, perf, docs, …); it becomes the bold prefix of the changelog bullet.

Adding one

Create a file with a short, unique name, e.g. changes/regex-namespace.md. Any filename works except this README.md, which the release step always skips.
