- 2026-04-25 — **Math methods (trig/log/hyperbolic/bit ops).** Added 22 missing Math methods to `runtime.sx`: `sin`, `cos`, `tan`, `asin`, `acos`, `atan`, `atan2`, `sinh`, `cosh`, `tanh`, `asinh`, `acosh`, `atanh`, `exp`, `log`, `log2`, `log10`, `expm1`, `log1p`, `clz32`, `imul`, `fround`. All use existing SX primitives. `clz32` uses log2-based formula; `imul` uses modulo arithmetic; `fround` stubs to identity. Addresses 36x "TypeError: not a function" in built-ins/Math (43% → ~79% expected). 529/530 unit (unchanged), 148/148 slice. Commit `5f38e49b`.
- 2026-04-25 — **`var` hoisting.** Added `js-collect-var-decl-names`, `js-collect-var-names`, `js-dedup-names`, `js-var-hoist-forms` helpers to `transpile.sx`. Modified `js-transpile-stmts`, `js-transpile-funcexpr`, and `js-transpile-funcexpr-async` to prepend `(define name :js-undefined)` forms for all `var`-declared names before function-declaration hoists. Shallow collection (direct statements only). 4 new tests: program-level var, hoisted before use → undefined, var in function, var + assign. 529/530 unit (+4), 148/148 slice unchanged. Commit `11315d91`.
- 2026-04-25 — **ASI (Automatic Semicolon Insertion).** Lexer: added `:nl` (newline-before) boolean to every token dict; `skip-ws!` sets it true when consuming `\n`/`\r`; `scan!` resets it to `false` at the start of each token scan. Parser: new `jp-token-nl?` helper reads `:nl` from the current token; `jp-parse-return-stmt` stops before parsing the expression when `jp-token-nl?` is true (restricted production: `return\nvalue` → `return undefined`). 4 new tests (flag presence, flag value, restricted return). 525/526 unit (+4), 148/148 slice unchanged. Commit `ae86579a`.
