* core: Stage 2 Task 2 tier 5a — compile defmulti + defmethod
defmulti/defmethod become macros (30-macros) over ctx-capturing
clojure.core fns (defmulti-setup/defmethod-setup, interned by
install-stateful-fns!):
- defmulti: (defmulti name dispatch & opts) -> (defmulti-setup 'name
dispatch ~@opts). name quoted; dispatch + opts (:default/:hierarchy)
evaluated. defmulti-setup builds the dispatch closure over the method
table and interns the var (same hierarchy/default/cache behavior).
- defmethod: (defmethod mm dval & fn-tail) -> (defmethod-setup 'mm dval
(fn ~@fn-tail)). The method impl is now a COMPILED (fn …) (was an
interpreted fn* eval). Auto-creates the multimethod if missing.
- removed their special-symbol? entries + eval-list arms, and dropped them
from host_iface special-names + loader stateful-head?.
Both compile + interpret as plain invokes; dispatch incl. :default and
derive/hierarchy works in both modes.
Tests: evaluator-test (defmulti case) + namespace-test now use init (these
forms are overlay macros now, so a bare make-ctx lacks them).
Gate green: conformance 269x3, fallback-zero 38/4, bootstrap-fixpoint
stage1==2==3, self-host, staged-bootstrap, sci-bootstrap, clojure-test-suite
>=4034/67, features 78/78, all unit + spec (multimethods 16/16).
* core: Stage 2 Task 2 tier 5b — compile deftype + defrecord
deftype becomes a macro (30-macros) over make-deftype-ctor (a ctx-capturing
clojure.core fn that bakes the ns-qualified type tag at def time) plus
extend-type for any inline protocol methods — so it compiles as a plain (do …).
Mirrors defrecord's existing field-let/protocol-grouping pattern.
- make-deftype-ctor-impl (evaluator) builds the ctor; interned as a closure.
- removed the deftype special-symbol? entry + eval-list arm; dropped deftype/
defrecord from host_iface special-names + loader stateful-head?.
- defrecord no longer redefines ->name via (Name. …) interop (frozen) — deftype
already provides ->name, so defrecord compiles too (map->name builds via it).
- field-kws spliced into a vector LITERAL ([~@…]) so the analyzer sees a vector
form, not a runtime pvec; type name + fields are unwrapped of ^meta (the reader
yields (with-meta sym m) forms, e.g. sci's (deftype ^{:doc …} Var …)).
With tier 5a, all of deftype/defrecord/defmulti/defmethod compile. The loader's
interpret-only set is now just the frozen host-coupled forms: defmacro/set!/./
new/eval.
Tests: evaluator-test deftype case uses init (deftype is an overlay macro now);
fallback-zero moves deftype off must-punt, adds deftype/defrecord/defmulti/
defmethod to must-compile (43/3).
Gate green (full jpm build + jpm test): conformance 269x3, fallback-zero 43/3,
bootstrap-fixpoint stage1==2==3, self-host, staged-bootstrap, sci-bootstrap
422/0, clojure-test-suite >=4034/67, all unit + spec.

Reorganize the flat 49-file test/ into three layers (jpm test recurses, so all
are still discovered):
- test/unit/ white-box component tests (reader, evaluator, types,
persistent-map, lazy-seq, macro, interop, compiler)
- test/integration/ cross-cutting + regression batteries (conformance, jank,
sci-bootstrap/runtime, features, systematic-coverage, api,
core, namespaces, ported clojure suites) and
.../ports/ ported clojure/cljs test batches pending consolidation
- test/spec/ the behavioral contract (built out in following commits)
- test/support/harness.janet shared defspec table runner (cases compared via
Jolt's own =, with a :throws sentinel) + expect= helpers
Files moved with git mv (history preserved) and import paths fixed for depth.
jpm test green. README Test section updated.
Next: build out test/spec/ to cover the public API area-by-area, mining the
integration batteries and filling gaps.
