giles	c4dd125210	Step 10c: desugared reactive pattern tests (8 new) ... Prove that provide/context/bind/peek replace signal/deref/computed for common reactive patterns: - counter, toggle (provide! replaces reset!/swap!) - derived values (bind replaces computed) - re-evaluation (bind replaces effect) - read-modify-write (peek + provide! replaces swap!) - nested state (nested provide replaces multiple signals) - batch coalescing with desugared pattern 2776/2776 OCaml tests pass.

giles	a965731a33	Step 10c: bind CEK special form + provide-set frame + scope-stack integration ... bind is now a CEK special form that captures its body unevaluated, establishes a tracking context (*bind-tracking*), and registers subscribers on provide frames when context reads are tracked. - bind special form: step-sf-bind, make-bind-frame, bind continue handler - provide-set frame: provide! evaluates value with kont (fixes peek bug) - context tracking: step-sf-context appends to *bind-tracking* when active - scope-stack fallback: provide pushes to scope stack for cek-call contexts - CekFrame mutation: cf_remaining/cf_results/cf_extra2 now mutable - Transpiler: subscribers + prev-tracking field mappings, *bind-tracking* in ml-mutable-globals - Test fixes: string-append → str, restored edge-cases suite Passing: bind returns initial value, bind with expression, bind with let, bind no deps is static, bind with conditional deps, provide! updates/multiple/nil, provide! computed new value, peek read-modify-write, guard inside bind, bind with string-append, provide! same value does not notify, bind does not fire on unrelated provide!, bind sees latest value, bind inside provide scope. Remaining: subscriber re-evaluation on provide! (scope-stack key issue), batch coalescing (no batch support yet).

giles	b3e9ebee1d	Step 10c: Vector type + unified reactive model test spec (34 tests) ... - Vector of value array added to sx_types.ml (prior commit) - Vector primitives in sx_primitives.ml (make-vector, vector-ref, vector-set!, vector-length, vector->list, list->vector) - R7RS vector tests - test-unified-reactive.sx: 34 tests specifying the unified reactive model (provide/context/peek/bind replacing signal/deref split). All 34 currently fail — implementation next. - WASM binary rebuilt Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-05 01:27:27 +00:00
