The names turn 2a's leak removal exposed as honestly missing, now proper: - slurp/spit/flush (host-classified): path-based IO over Janet files; spit takes :append; flush flushes *out*. printf prints formatted (no newline) over the existing format. file-seq walks paths via two host dir primitives through the overlay's tree-seq. - ns-map / ns-unmap / ns-refers (ctx fns). ns-refers required fixing the refer MODEL: refer/use/:refer now map the SOURCE VAR into the target ns (the Clojure model) instead of copying its value into a new var — so source-ns redefinitions propagate, the :macro flag travels for free, and refers are identifiable by the var's home :ns. - Thread-binding family: with-bindings*/with-bindings, bound-fn*/bound-fn, bound?, thread-bound?, get-thread-bindings. The captured binding map is a Janet struct keyed by the var tables — the exact frame representation var-get reads — so it re-pushes correctly (a phm frame is invisible to var lookup). - load-string and eval interned as VALUES at the api layer (they need the loader's compile-or-interpret routing); the eval special form still handles direct calls. Suite 4532 -> 4572 (baseline floor 4540 across timeout variance, clean 86), conformance 326x3, stdlib battery, all specs+unit (+21 turn-2b rows). Coverage: missing-portable 27 -> 10 (left: the *in*-model readers, the with-local-vars/with-precision/extenders tail). |

The Clojure Language Specification (Draft)
A normative, implementation-independent specification of the Clojure
language, developed alongside jolt's self-hosted compiler and validated by
its executable conformance suites. Why: Clojure has no spec — every
alternative implementation re-derives semantics from the reference
implementation and folklore. See the RFC for motivation, scope, evidence
sources, and process: ../rfc/0001-language-specification.md.

Current numbers (2026-06-10)
Of the 694 clojure.core vars in the ClojureDocs inventory:
- 380 implemented in jolt and exercised by the behavioral suites
- 154 implemented but not directly tested — each gets a test with its spec entry
- 35 portable but missing from jolt (
parse-long/parse-double/parse-boolean,update-keys/update-vals,macroexpand,time,partitionv/partitionv-all/splitv-at,with-redefs,with-open, reader fns, ns-introspection stragglers, …) — tracked as implementation gaps - 22 resolvable in code but invisible to ns introspection
(
resolve/ns-publicscan't see seed-fallback names likecompare,gensym,type) — a conformance finding in its own right - the rest classified host/JVM/concurrency (see dashboard)
How this connects to the test suites
test/integration/conformance-test.janet— 302 assertions, each run through three independent execution paths (interpreter, bootstrap compiler, self-hosted compiler) that must agree. Spec entries cite these.test/spec/*.janet— ~1,500 behavioral cases organized by topic.vendor/clojure-test-suite— the cross-dialect suite (≥4081 assertions passing); dialect splits there are classification evidence.- jank's per-construct corpus (
~/src/jank/compiler+runtime/test/jank) is the granularity model for §2/§3 conformance.
The invariant: every numbered normative statement names its conformance test, or is marked UNVERIFIED. The spec cannot drift from the implementations that check it.
