The dashboard's missing-portable category is now EMPTY (was 35 when the issue was filed; this session's io/leaf work had already landed most of them). The final seven: - extenders — ctx-capturing clojure.core fn over the protocol type-registry: the type-tags implementing a protocol, as symbols; nil when none - find-keyword — keyword: jolt keywords have no intern table, so it always finds (babashka makes the same call) - inst-ms* — the raw Inst method; one inst representation, so = inst-ms - read+string — over the 50-io readers, which now expose :buf and :fill-fn; returns [form exact-text-consumed], EOF throws or yields [eof-value ""] with the 3-arity, works for string AND stdin readers - with-local-vars — fresh free-standing var cells (__local-var seam) bound as locals; var-get/var-set work on any cell - with-open — canonical recursive expansion closing through the __close seam: a map-like value's :close fn or a host file (no .close interop here); nested closes run inner-first, finally runs on throw - with-precision — body evaluates with precision/:rounding accepted and ignored (doubles, no BigDecimal context) — documented divergence 30 new spec rows (test/spec/missing-vars-spec.janet); coverage.md regenerated: implemented+tested 426 -> 433, missing-portable 7 -> 0. Gate: jpm exit 0, all tests passed. |

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.

python3 tools/spec_coverage.py (requires clojuredocs-export.json in the
repo root and a working jolt checkout).
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.
