giles	29c90a625b	Delete evaluator.py shim: all imports go directly to bootstrapped sx_ref.py ... EvalError moved to types.py. All 27 files updated to import eval_expr, trampoline, call_lambda, etc. directly from shared.sx.ref.sx_ref instead of through the evaluator.py indirection layer. 320/320 spec tests pass.

giles	3ca89ef765	Self-hosted z3.sx translator, prove.sx prover, parser unicode, auto reader macros ... - z3.sx: SX-to-SMT-LIB translator written in SX (359 lines), replaces Python translation logic - prove.sx: SMT-LIB satisfiability checker in SX — proves all 91 primitives sat by construction - Parser: support unicode characters (em-dash, accented letters) in symbols - Auto-resolve reader macros: #name finds name-translate in component env, no Python registration - Platform primitives: type-of, symbol-name, keyword-name, sx-parse registered in primitives.py - Cond heuristic: predicates ending in ? recognized as Clojure-style tests - Library loading: z3.sx loaded at startup with reload callbacks for hot-reload ordering - reader_z3.py: rewritten as thin shell delegating to z3.sx - Split monolithic .sx files: essays (22), plans (13), reactive-islands (6) into separate files Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-08 22:47:53 +00:00
giles	03ba8e58e5	Implement reader macros (#;, #|...|, #', #name) and #z3 demo ... Reader macros in parser.sx spec, Python parser.py, and hand-written sx.js: - #; datum comment: read and discard next expression - #|...| raw string: no escape processing - #' quote shorthand: (quote expr) - #name extensible dispatch: registered handler transforms next expression #z3 reader macro demo (reader_z3.py): translates define-primitive declarations from primitives.sx into SMT-LIB verification conditions. Same source, two interpretations — bootstrappers compile to executable code, #z3 extracts proof obligations. 48 parser tests (SX spec + Python), all passing. Rebootstrapped JS+Python. Demo page at /plans/reader-macro-demo with side-by-side examples. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-08 20:21:40 +00:00
