require/in-ns take quoted (already-evaluated) args, so they become ordinary ctx-capturing clojure.core fns (install-stateful-fns!): - require-impl (varargs over specs -> eval-require) / in-ns-impl, extracted from the eval-list special arms. - removed their eval-list match arms (they fall through to the function-call default, resolving the interned closures) and dropped them from host_iface special-names + loader stateful-head? + compiler uncompilable-heads. require+alias+refer and in-ns now compile + interpret as plain invokes. Tests: namespace-test uses bare make-ctx, so it now installs the stateful fns via a fresh-ctx helper (api/init does this automatically). fallback-zero moves require off must-punt and adds require/in-ns/defprotocol/extend-type/ reify/(var map) to must-compile (37 now); deftype takes require's must-punt slot. Gate green: conformance 267x3, fallback-zero 37/5, bootstrap-fixpoint stage1==2==3, self-host, staged-bootstrap, clojure-test-suite >=4034/67, features 78/78, deps-loader, all unit + spec (namespaces 24/24).

# Fallback-zero verification (Stage 1 Task 3).

#
|
|
# self-host-test.janet checks observable RESULTS but not WHICH path ran — a form
|
|
# that silently fell back to the interpreter still "passes" there. This harness
|
|
# checks the path: it runs the portable analyzer (jolt.analyzer/analyze, via
|
|
# backend/analyze-form) on a corpus of NON-STATEFUL forms and asserts NONE raise
|
|
# :jolt/uncompilable — i.e. the self-hosted analyzer actually COMPILED them.
|
|
#
|
|
# As analyzer↔compiler.janet parity grows (Stage 1), move forms from the
|
|
# "intentional fallback" sanity list into the must-compile corpus. The day the
|
|
# fallback set equals the frozen intentional stateful set, the Janet bootstrap
|
|
# compiler is retireable.
|
|
#
|
|
# Mechanism: backend/analyze-form throws (a "jolt/uncompilable: …" string) for a
|
|
# punted form; (protect …) turns that into [false msg]. [true ir] == compiled.
