The transient assoc! accepted an odd key/val count and silently assigned
nil to the dangling key — non-Clojure, and inconsistent with the seed's
own plain assoc (which throws) and Clojure's assoc!. Make it throw.
Updates the 4 'assoc! odd args' transient spec rows to 3 :throws + 1
even-args positive, and regenerates corpus.edn. The Chez host already
threw on these, so this only realigns the corpus contract.
Emit a :quote node by reconstructing the raw reader form as RT constructor
calls: symbol -> jolt-symbol, list (array) -> jolt-list, vector (tuple) ->
jolt-vector, map -> jolt-hash-map, set -> jolt-hash-set, scalars via emit-const.
The runtime value of a quote is just that literal data (the interpreter returns
the reader form verbatim).
Quote exposed a latent seq.ss bug: empty map/filter results were jolt-nil, but
Clojure's (map f []) is an empty seq, so (= () (map f [])) must be true. Return
jolt-empty-list (which seqs back to nil, so it's still a valid lazy-tail
terminator) instead — matching jolt-take/drop/rest/list.
Prelude emit reach 334 -> 342/355. Subset probe 632 -> 664/664 compiled, 0
divergences (quote + the seq fix pull 32 corpus cases into the subset). emit-test
110/110 (added 16 quote cases). corpus.edn regenerated (the 3 malformed-catch
spec rows). Full gate green.
0a (host/chez/values.ss): Jolt value model on Chez — nil sentinel distinct from
#f/'(), interned keywords, ns+meta symbols, exactness-aware = and consistent
hash. Chez numeric tower gives ratios/bignums free. 33/33 tests.
0b (test/chez/): extract test/spec/*.janet defspec tables into corpus.edn (2655
cases, valid as both EDN and Janet data), and a runner that drives ANY jolt
binary via the CLI boundary with per-case subprocess isolation. Pluggable target
(JOLT_BIN) so the same corpus gates every host. Baseline vs Janet build/jolt:
2641/2655, 14 known CLI divergences allowlisted; gate fails only on NEW ones.
