Fifteen vars from the spec coverage gap (docs/spec/coverage.md): parse-long/parse-double/parse-boolean (strict validation; scan-number alone accepts 0x10), newline, current-time-ms (host clock for time), update-keys/ update-vals (PHM base, collisions last-wins), partitionv/partitionv-all/ splitv-at (lazy seqs of vectors; splitv-at's tail stays a seq, matching the reference), with-redefs/with-redefs-fn (roots restored on throw), time, macroexpand (expand-1 to fixpoint), alias/ns-unalias (write BOTH alias stores — require :as uses string-keyed :imports while ns-aliases reads :aliases; split filed), ns-publics (symbol-keyed map; publics == interns, no privacy). Three pre-existing bugs fixed along the way: - (partition n step pad coll) misparsed pad as the coll and returned () - (require 'bare.symbol) rejected — only vector specs were accepted - analyze-form leaked the interpreted analyzer's ns on a punt: a throw out of the analyzer left current-ns=jolt.analyzer and :compile-ns set, so the fallback interpretation resolved user vars against the wrong namespace (bit (var user-sym) under compile mode) And one overlay-authoring landmine documented in-code: a 20-coll fn must not use 30-macros macros (with-redefs-fn's dotimes compiled as a forward ref that resolved to the macro fn at runtime) — loop/recur instead. Gate: conformance 316x3 (+14 rows), suite 4324 pass / 78 clean (was 4081/72; parse_*/update_* files now contribute), baselines raised, all specs+unit, fixpoint, self-host, sci, staged. Coverage: missing-portable 35 -> 20.
