a8c453183f Phase 4: Macro expansion in compiler
- resolve-macro: resolve symbols to macro vars via ctx
- Macro expansion in analyze-form: detects macro heads, expands, re-analyzes
- compile-ast: emits Janet data structures with resolved core fn values
- compile-and-eval uses compile-ast (no source parse roundtrip)
- eval-string routes macros through compiler (expanded at analyze time)
- Fix - mapping: core-sub (core-- doesn't exist)
- All 317 tests pass + 6 new Phase 4 macro tests

ab7ff85816 Phase 3: Compile-aware loader, :compile? flag, compile-and-eval
- loader.janet: load-ns with compile? dispatch, compiled-cache, compiled?, clear-compiled-cache
- compiler.janet: compile-ast (Janet data structures for direct eval), compile-and-eval
- api.janet: compile-string, compile-file, eval-string dispatches to compile-and-eval when :compile? is true
- types.janet: :compile? flag and :compiled-cache table in context env
- Stateful forms (def, defmacro, ns, deftype, defmulti, defmethod) fall back to interpreter
- All 317 tests pass + 16 new Phase 3 tests

dfa98746ee Phase 1+2: Clojure→Janet source compiler with symbol classification
- analyze-form: Clojure forms → annotated AST nodes (:op keys)
- emit-ast: AST dispatch → Janet source via StringBuffer
- compile-form: analyze → emit → Janet source string
- Symbol classification: locals, core refs, qualified refs
- Ops: const, do, if, def, fn, let, invoke, quote, vector, map
- Local binding awareness in fn* and let* (shadowing works)
- All 317 existing tests pass, 24 new compiler tests

679cc1d4ef fix: persistent hash map — simple array-based, fully working
Replaced bit-trie HAMT with simple array-based implementation.
Janet 64-bit doubles cannot reliably express 32-bit signed integer
operations required by HAMT (bitmap indexing, popcount, etc).

New design:
- find-key-index: linear scan for key matching
- node-assoc: append-to-array on new key, clone+update on existing
- node-find: linear scan for value retrieval
- O(n) for small maps, equivalent semantics

All operations verified:
  (hash-map :a 1)         → {:root [:a 1], count=1}
  (hash-map :a 1 :b 2)    → {:root [:a 1 :b 2], count=2}
  phm-assoc/phm-get/phm-count/phm-contains? all correct
  Value replacement preserves count correctly

979486600a fix: persistent hash map — working with simple array implementation
Root cause of HAMT failure: Janet uses 64-bit doubles, bit operations
require 32-bit signed ints. Hash values from Janet exceed this range.

Solution: Replaced bit-trie HAMT with simple array-based implementation:
- find-key-index: linear scan for key lookup
- node-assoc: append-to-array on insert, clone+update on replace
- node-find: linear scan for value retrieval

All operations work correctly:
  (hash-map :a 1)          → {:root [:a 1], :count 1}
  (hash-map :a 1 :b 2)    → {:root [:a 1 :b 2], :count 2}
  phm-assoc / phm-get / phm-count all verified

O(n) lookup (acceptable for small maps). HAMT can be reintroduced
once Janet gets proper 32-bit int support or we implement bit ops
in pure Janet.

5052e391da perf: clean HAMT persistent hash map, 18-form .clj source
Rewrite persistent_hash_map.clj with correct paren balancing.
BitmapIndexedNode constructor + bit-or verified working in isolation.
Core HAMT operations (bmn-assoc, bmn-find, phm-assoc, phm-get,
phm-contains?, hash-map) structurally correct.

Calling phm-assoc at runtime fails with 64-bit hash overflow
in Janet bit ops — hash values exceed 32-bit signed range.
Fix: wrap (hash key) with (bit-and (int h) 0x7FFFFFFF) in phm-assoc.

33a5b7e7a4 feat: persistent vector (working) + HAMT hash map (wip)
PersistentVector: 17-form .clj source, fully working.
- 32-way branching trie with tail optimization
- pv-conj, pv-nth, pv-assoc, pv-pop, vector?, vector constructor
- instance? check works on deftype tables
- .-field accessor syntax for deftype fields

api.janet: :mutable? compile flag for opt-out
- Default: persistent data structures loaded
- Pass {:mutable? true} to use Janet native types

Supporting changes (evaluator/core):
- 17 new primitives: bit ops, array ops, unchecked math, hash, cond
- loop macro, zero?, dec/inc, defn multi-arity
- instance? for deftype tables (get val :jolt/deftype)
- defrecord builds maps at expansion time
- .-field field access in default function application path

PersistentHashMap: 24-form HAMT source loads OK.
- BitmapIndexedNode/PersistentHashMap deftypes
- mask, bitpos, bit-count, index helpers
- phm-assoc/phm-get/phm-without/phm-contains? stubs
- bmn-assoc insert path structured, bitmap propagation wip

794f60dff2 fix: vendor/sci submodule, defrecord fix, all tests pass
- Add SCI as git submodule at vendor/sci (replaces absolute path)
- Fix defrecord macro: emit array-map at expansion time, no interleave dep
- Remove stale test files (test-ctor, test-parser, edamame_shim)
- All 317 SCI forms load with 0 failures, 9 test suites green

6e0b95aaae feat: SCI eval-string via Jolt-native reader/evaluator
Replace SCI's internal interpreter/parser/analyzer pipeline with
Jolt-native eval-string that delegates to Jolt's reader and evaluator.
All 317 SCI source forms load, 9 namespaces populated, 46 total ns.

eval-string result: (+ 1 2 3) → 6, (def x 42) x → 42

Removed edamame/core shim — no longer needed since we bypass
the SCI internal eval pipeline entirely.

b948c4fdbb fix: all 317 SCI forms load, zero failures
- Reorder load sequence: types→unrestrict→vars→lang→utils→namespaces→core
- Add if-let/when-let/if-some/when-some/let macros and register in core-macro-names
- Add stubs: resolve, update, copy-core-var, copy-var, macrofy, new-var, avoid-method-too-large
- Add dynamic vars: *1, *2, *3, *e, *assert with nil-sentinel
- Fix core-update: use put instead of Janet's update (struct-incompatible)
- Change *clojure-version* from struct to table (mutable for update)
- Fix core-avoid-method-too-large: return @{} not nil
- Fix init-core! nil-sentinel unwrapping
- Fix let* destructuring for {:keys [...]} and sequential patterns
- Fix fn*/defmacro: capture defining ns for symbol resolution in closures
