- cek_run patched to handle import suspensions via _import_hook. define-library (import ...) now resolves cleanly on the server. IO suspension errors: 190 → 0. JIT failures: ~50 → 0. - _import_hook wired in sx_server.ml to load .sx files on demand. - compile-modules.js syncs source .sx files to dist/sx/ before compiling — eliminates stale bytecode from out-of-date copies. - WASM binary rebuilt with all fixes. - 2658/2658 tests pass (8 new — previously failing import tests).

;; freeze.sx — Serializable state boundaries
|
|
;;
|
|
;; Freeze scopes collect signals registered within them. On freeze,
|
|
;; their current values are serialized to SX. On thaw, values are
|
|
;; restored. Multiple named scopes can coexist independently.
|
|
;;
|
|
;; This is a library built on top of the evaluator's scoped effects
|
|
;; (scope-push!/scope-pop!/context) and signal system. It is NOT
|
|
;; part of the core evaluator — it loads after evaluator.sx.
|
|
;;
|
|
;; Usage:
|
|
;; (freeze-scope "editor"
|
|
;; (let ((doc (signal "hello")))
|
|
;; (freeze-signal "doc" doc)
|
|
;; ...))
|
|
;;
|
|
;; (cek-freeze-scope "editor") → {:name "editor" :signals {:doc "hello"}}
|
|
;; (cek-thaw-scope "editor" frozen-data) → restores signal values
|
|
;; ==========================================================================
|
|

|
;; Registry of freeze scopes: name → list of {name signal} entries
