Yogthos e3c14e656c java.time Phase 2: Duration/Period, enums, ChronoUnit/Field machinery 
Duration (ISO PT.. toString, between, full arithmetic), Period (between with
borrow, P.. toString, normalized), full Month/DayOfWeek enums (named constants,
print as their name — fixes the Phase-1 raw-jhost print), Year, YearMonth
(2020-02 toString, leap, atDay/atEndOfMonth), ChronoUnit (between/getDuration)
and ChronoField. The temporal machinery on the Phase-1 types now works with
ChronoUnit/ChronoField: (.plus t n DAYS), (.until t1 t2 unit), (.get/.getLong
t field), (.with t field v), (.isSupported ..), (.truncatedTo ..).

Analyzer: (. Class method args) with a class target lowers to a static call
(Class/method args) instead of mis-dispatching as an instance call on the arg
— matches JVM; needed by cljc.java-time.year. Seed re-minted; selfhost holds.

The Phase-2 cljc.java-time namespaces load; tick.core advances to a Phase-3
zone gap. 10 corpus rows certified vs JVM. make test + shakesmoke green, 0 new
divergences, data.json stays 138/139.

Chez bootstrap seed

These two files are the bootstrap compiler for jolt — the seed that makes the build self-hosting:

  • prelude.ss — the clojure.core prelude (all tiers + clojure.string/walk/ template/edn/set/pprint) as Scheme def-var! forms.
  • image.ss — the compiler image (jolt.ir + jolt.analyzer + jolt.backend-scheme) as Scheme def-var! forms.

Both are generated, not hand-written. They are checked in because a fresh checkout must be able to build jolt-on-Chez using only Chez: host/chez/bootstrap.ss loads this seed, then rebuilds the prelude + image from the .clj/.ss sources via the on-Chez compiler (read → analyze → emit, all on Chez). The seed is a joint byte-fixpoint: rebuilding from an up-to-date seed reproduces it exactly. make selfhost (host/chez/selfcheck.sh) runs host/chez/bootstrap.ss and diffs the rebuilt artifacts against the checked-in seed.

Re-minting

When the seed sources change (the core tiers, the compiler namespaces, the host contract, the reader, emit-image.ss), the seed drifts and make selfhost fails. Re-mint it by running host/chez/bootstrap.ss and writing the freshly rebuilt prelude/image back to host/chez/seed/prelude.ss / host/chez/seed/image.ss, then commit the refreshed files.
