js-on-sx: wrapper constructor-detection, Array.prototype.toString, >>> operator

Number.__callable__ and String.__callable__ now check this.__proto__ ===
Number/String.prototype before writing wrapper slots, preventing false-positive
mutation when called as plain function. js-to-number extended to unwrap
wrapper dicts and call valueOf/toString for plain objects. Array.prototype.toString
replaced with a direct js-list-join implementation (eliminates infinite recursion
via js-invoke-method on dict-based arrays). >>> added to transpiler + runtime.

String test262 subset: 62→66/100. 529/530 unit, 147/148 slice.

-# HS conformance — blockers drain
-
-Goal: take hyperscript conformance from **1277/1496 (85.4%)** to **1496/1496 (100%)** by clearing the blocked clusters and the design-done Bucket E subsystems.
-
-This plan exists because the per-iteration `loops/hs` agent can't fit these into its 30-min budget — they need dedicated multi-commit sit-downs. Track progress here; refer to `plans/hs-conformance-to-100.md` for the canonical cluster ledger.
-
-## Current state (2026-04-25)
-
-- Loop running in `/root/rose-ash-loops/hs` (branch `loops/hs`)
-- sx-tree MCP **fixed** (was a session-stale binary issue — restart of claude in the tmux window picked it up). Loop hinted to retry **#32**, **#29** first.
-- Recent loop progress: ~1 commit/6h — easy wins drained, what's left needs focused attention.
-
-## Remaining work
-
-### Bucket-A/B/C blockers (small, in-place fixes)
-
-| # | Cluster | Tests | Effort | Blocker | Fix sketch |
-|---|---------|------:|--------|---------|------------|
-| **17** | `tell` semantics | +3 | ~1h | Implicit-default-target ambiguity. `bare add .bar` inside `tell X` should target `X` but explicit `to me` must reach the original element. | Add `beingTold` symbol distinct from `me`; bare commands compile to `beingTold-or-me`; explicit `me` always the original. |
-| **22** | window global fn fallback | +2-4 | ~1h | `foo()` where `foo` isn't SX-defined needs to fall back to `(host-global "foo")`. Three attempts failed: guard (host-level error not catchable), `env-has?` (not in HS kernel), `hs-win-call` (NativeFn not callable from CALL). | Add `symbol-bound?` predicate to HS kernel **OR** a host-call-fn primitive with arity-agnostic dispatch. |
-| **29** | `hyperscript:before:init` / `:after:init` / `:parse-error` events | +4-6 | ~30m (post sx-tree fix) | Was sx-tree MCP outage. Now unblocked — loop should retry. 4 of 6 tests need stricter parser error-rejection (out of scope; mark partial). | Edit `integration.sx` to fire DOM events at activation boundaries. |

-| # | Cluster | Tests | Effort | Status |
-|---|---------|------:|--------|--------|
-| **31** | runtime null-safety error reporting | **+15-18** | **2-4h** | **THIS SESSION'S TARGET.** Plan node fully spec'd: 5 pieces of work. |
-| **32** | MutationObserver mock + `on mutation` | +10-15 | ~2h | Was sx-tree-blocked. Now unblocked — loop hinted to retry. Multi-file: parser, compiler, runtime, runner mock, generator skip-list. |
-| **33** | cookie API | +2 (remaining) | ~30m | Partial done (+3). Remaining 2 need `hs-method-call` runtime fallback for unknown methods + `hs-for-each` recognising host-array/proxy collections. |
-| 34 | event modifier DSL | +6-8 | ~1-2h | `elsewhere`, `every`, count filters (`once`/`twice`/`3 times`/ranges), `from elsewhere`. Pending. |
-| 35 | namespaced `def` | +3 | ~30m | Pending. |
-
-### Bucket E — subsystems (design docs landed, multi-commit each)
-
-Each has a design doc with a step-by-step checklist. These are 1-2 days of focused work each, not loop-fits.

-### Bucket F — generator translation gaps
-
-~25 tests SKIP'd because `tests/playwright/generate-sx-tests.py` bails with `return None`. Single dedicated generator-repair sit-down once Bucket D is drained. ~half-day.
-
-## Order of attack
-
-In approximate cost-per-test order:
-
-1. **Loop self-heal** (no human work) — wait for #29, #32 to land via the running loop ⏱️ ~next 1-2 hours
-2. **#31 null-safety** — biggest scoped single win, dedicated worktree agent (this session)
-3. **#33 cookie API remainder** — quick partial completion
-4. **#17 / #22 / #34 / #35** — small fiddly fixes, one sit-down each
-5. **Bucket E** — pick one subsystem at a time. **#39 (WebWorker stub) first** — single commit, smallest. Then **#38 (SourceInfo)** — 4 commits. Then the bigger three (#36, #37, #40).
-6. **Bucket F** — generator repair sweep at the end.
-
-Estimated total to 100%: ~10-15 days of focused work, parallelisable across branches.
-
-## Cluster #31 spec (full detail)
-
-The plan note from `hs-conformance-to-100.md`:
-
-> 18 tests in `runtimeErrors`. When accessing `.foo` on nil, emit a structured error with position info. One coordinated fix in the compiler emit paths for property access, function calls, set/put.
-
-**Required pieces:**
-
-1. **Generator-side `eval-hs-error` helper + recognizer** for `expect(await error("HS")).toBe("MSG")` blocks. In `tests/playwright/generate-sx-tests.py`.
-2. **Runtime helpers** in `lib/hyperscript/runtime.sx`:
-   - `hs-null-error!` raising `'<sel>' is null`
-   - `hs-named-target` — wraps a query result with the original selector source
-   - `hs-named-target-list` — same for list results
-3. **Compiler patches at every target-position `(query SEL)` emit** — wrap in named-target carrying the original selector source. ~17 command emit paths in `lib/hyperscript/compiler.sx`:
-   add, remove, hide, show, measure, settle, trigger, send, set, default, increment, decrement, put, toggle, transition, append, take.
-4. **Function-call null-check** at bare `(name)`, `hs-method-call`, and `host-get` chains, deriving the leftmost-uncalled-name (`'x'` / `'x.y'`) from the parse tree.
-5. **Possessive-base null-check** (`set x's y to true` → `'x' is null`).
-
-**Files in scope:**
-- `lib/hyperscript/runtime.sx` (new helpers)
-- `lib/hyperscript/compiler.sx` (~17 emit-path edits)
-- `tests/playwright/generate-sx-tests.py` (test recognizer)
-- `tests/hs-run-filtered.js` (if mock helpers needed)
-- `shared/static/wasm/sx/hs-runtime.sx` + `hs-compiler.sx` (WASM staging copies)
-
-**Approach:** target-named pieces incrementally — runtime helpers first (no compiler change), then compiler emit paths in batches (group similar commands), then function-call/possessive at the end. Each batch is one commit if it lands +N tests; mark partial if it only unlocks part.
-
-**Watch for:** smoke-range regressions (tests flipping pass→fail). Each commit: rerun smoke 0-195 and the `runtimeErrors` suite.
-
-## Notes for future sessions
-
-- `plans/hs-conformance-to-100.md` is the canonical cluster ledger — update it on every commit.
-- `plans/hs-conformance-scoreboard.md` is the live tally — bump `Merged:` and the bucket roll-up.
-- Loop has scope rule "never edit `spec/evaluator.sx` or broader SX kernel" — most fixes here stay in `lib/hyperscript/**`, `tests/`, generator. If a fix needs kernel work, surface to the user; don't merge silently.
-- Cluster #22's `symbol-bound?` predicate would be a kernel addition — that's a real cross-boundary scope expansion.

 ## Progress log
 
-### 2026-04-26 — Bucket F: array literal arg to JS fn (+1)
-- **da2e6b1b** — `HS Bucket F: array literal arg to JS fn fix (+1 test)`. Two-part fix: (a) `generate-sx-tests.py` `js_expr_to_sx` now translates `arr.reduce(fn, init)` → `(reduce fn init arr)`, `.map(fn)` → `(map fn arr)`, `.filter(fn)` → `(filter fn arr)` so SX list arguments work with JS array HO methods. (b) `host-call-fn` in `hs-run-filtered.js` adds `sxToJs` recursive converter that unwraps SX list `._type==='list'` to native JS arrays before calling native JS functions. Together these fix functionCalls "can pass an array literal as an argument". Suite hs-upstream-expressions/functionCalls: 8/12 (unchanged SKIP ratio). Test 597: 0/1 → 1/1. Smoke 0-195: 175/195 unchanged.

-- **daea2808** — `HS Bucket F: fix hs-make-object _order + assert= for dicts (+1 test)`. Two-part fix: (a) `runtime.sx` `hs-make-object` no longer appends `_order` key to HS object literals — V8's native string-key insertion order is sufficient, and the hidden key was breaking structural equality. (b) `generate-sx-tests.py` `emit_eval` now detects when `expected_sx` contains `{` (dict syntax) and emits `assert-equal` (which uses `equal?` for deep structural equality) instead of `assert=` (which uses `=`, reference equality for dicts). Together these fix arrayLiteral "arrays containing objects work". Suite hs-upstream-expressions/arrayLiteral: 7/8 → 8/8. Smoke 0-195 unchanged at 175/195.

-### 2026-04-26 — Bucket F: empty multi-element fix (+1)
-- **875e9ba3** — `HS: empty multi-element fix (+1 test)`. `empty .class` compiled `(empty-target (query ".class"))` through `hs-to-sx` → `(hs-empty-target! (hs-query-first ".class"))` which only emptied the first match. Fix: detect `(query ...)` target in the `empty-target` compiler case and emit `(for-each (fn (_el) (hs-empty-target! _el)) (hs-query-all sel))`, mirroring the `add-class` pattern. Suite hs-upstream-empty: 12/13 → 13/13. Smoke 0-195: 175/195 unchanged.
-
-### 2026-04-26 — Bucket F: add CSS template interpolation (+1)
-- **5a76a040** — `HS: add CSS template interpolation fix (+1 test)`. `add {color: ${}{"red"}}` uses two consecutive brace groups: the empty `${}` marker followed by `{"red"}` for the actual value. The prior parser fix called `parse-expr` when already at the closing `}` of the empty group, returning nil. Fix: detect the empty-brace case (`brace-open` → immediately `brace-close`), skip it, then read the actual value from the next `{…}` block. Also handles normal `${expr}` correctly. Suite hs-upstream-add: 17/19 → 18/19. Smoke 0-195: 174/195 → 175/195.

Wrapped call-expr in `emit-set (quote the-result) ...` so both `it` and `the-result` are updated. Suite hs-upstream-call: 5/6 → 6/6. Smoke 0-195: 173/195 → 174/195.

-### 2026-04-26 — cluster 7 put hyperscript reprocessing (done, final +1)
-- **247bd85c** — `hs: register promiseAString/promiseAnInt as sync test fixtures (+1 test)`. Upstream test "waits on promises" calls `promiseAString()` via window global. OCaml run_tests.ml registers these as NativeFns returning "foo"/"42" synchronously; JS runner had no equivalent. Added `globalThis.promiseAString = () => 'foo'` and `globalThis.promiseAnInt = () => 42` to hs-run-filtered.js. Suite hs-upstream-put: 37/38 → 38/38 (fully done). Smoke 0-195: 173/195 unchanged.

-### 2026-04-26 — cluster 7 put hyperscript reprocessing (partial +3 more)
-- **d663c91f** — `hs: stop event propagation after each hs-on handler fires (+3 tests)`. Root cause: click events bubble from b1 (inside d1) to d1, causing d1's `on click put ...` handler to re-fire and replace the just-modified b1 with fresh content (text=40). Fix: `hs-on`'s wrapped handler now calls `event.stopPropagation()` after each handler runs, preventing the bubbled click from reaching ancestor HS listeners. Tests 1147/1149/1150 now pass. Suite hs-upstream-put: 34/38 → 37/38. Smoke 0-195: 173/195 unchanged. One test remains: "waits on promises" (async/Promise issue).

-### 2026-04-25 — Bucket F: in-expression filter semantics (+1)
-- **67a5f137** — `HS: in-expression filter semantics (+1 test)`. `1 in [1, 2, 3]` was returning boolean `true` instead of the filtered list `(list 1)`. Root cause: `in?` compiled to `hs-contains?` which returns boolean for scalar items. Fix: (a) `runtime.sx` adds `hs-in?` returning filtered list for all cases, plus `hs-in-bool?` which wraps with `(not (hs-falsy? ...))` for boolean contexts; (b) `compiler.sx` changes `in?` clause to emit `(hs-in? collection item)` and adds new `in-bool?` clause emitting `(hs-in-bool? collection item)`; (c) `parser.sx` changes `is in` and `am in` comparison forms to produce `in-bool?` so those stay boolean. Suite hs-upstream-expressions/in: 8/9 → 9/9. Smoke 0-195: 173/195 unchanged.

-### 2026-04-25 — cluster 22 window global fn fallback (+1)
-- **d31565d5** — `HS cluster 22: simplify win-call emit + def→window + init-blocks test (+1)`. Two-part change building on 337c8265 (host-call-fn FFI + hs-win-call runtime). (a) `compiler.sx` removes the guard wrapper from bare-call and method-call `hs-win-call` emit paths — direct `(hs-win-call name (list args))` is sufficient since hs-win-call returns nil for unknown names; `def` compilation now also emits `(host-set! (host-global "window") name fn)` so every HS-defined function is reachable via window lookup. (b) `generate-sx-tests.py` fixes a quoting bug: `\"here\"` was being embedded as three SX nodes (`""` + symbol + `""`) instead of a single escaped-quote string; fixed with `\\\"` escaping. Hand-rolled deftest for `can refer to function in init blocks` now passes. Suite hs-upstream-core/regressions: 13/16 → 14/16. Smoke 0-195: 172/195 → 173/195.

-### 2026-04-25 — cluster 11/33 followups: hide strategy + cookie clear (+2)
-- **5ff2b706** — `HS: cluster 11/33 followups (+2 tests)`. Three orthogonal fixes that pick up tests now unblocked by earlier work. (a) `parser.sx` `parse-hide-cmd`/`parse-show-cmd`: added `on` to the keyword set that flips the implicit-`me` target. Previously `on click 1 hide on click 2 show` silently parsed as `(hs-hide! nil ...)` because `parse-expr` started consuming `on` and returned nil; now hide/show recognise a sibling feature and default to `me`. (b) `runtime.sx` `hs-method-call` fallback for non-built-in methods: SX-callables (lambdas) call via `apply`, JS-native functions (e.g. `cookies.clear`) dispatch via `(apply host-call (cons obj (cons method args)))` so the native receives the args list. (c) Generator `hs-cleanup!` body wrapped in `begin` (fn body evaluates only the last expr) and now resets `hs-set-default-hide-strategy! nil` + `hs-set-log-all! false` between tests — the prior `can set default to custom strategy` cluster-11 test had been leaking `_hs-default-hide-strategy` into the rest of the suite, breaking `hide element then show element retains original display`. New cluster-33 hand-roll for `basic clear cookie values work` exercises the method-call fallback. Suite hs-upstream-hide: 15/16 → 16/16. Suite hs-upstream-expressions/cookies: 3/5 → 4/5. Smoke 0-195 unchanged at 172/195.

-### 2026-04-25 — cluster 35 namespaced def + script-tag globals (+3)
-- **122053ed** — `HS: namespaced def + script-tag global functions (+3 tests)`. Two-part change: (a) `runtime.sx` `hs-method-call` gains a fallback for unknown methods — `(let ((fn-val (host-get obj method))) (if (callable? fn-val) (apply fn-val args) nil))`. This lets `utils.foo()` dispatch through `(host-get utils "foo")` when `utils` is an SX dict whose `foo` is an SX lambda. (b) Generator hand-rolls 3 deftests since the SX runtime has no `<script type='text/hyperscript'>` tag boot. For `is called synchronously` / `can call asynchronously`: `(eval-expr-cek (hs-to-sx (first (hs-parse (hs-tokenize "def foo() ... end")))))` registers the function in the global eval env (eval-expr-cek processes `(define foo (fn ...))` at top scope), then a click div is built via dom-set-attr + hs-boot-subtree!. For `functions can be namespaced`: define `utils` as a dict, register `__utils_foo` as a fresh-named global def, then `(host-set! utils "foo" __utils_foo)` populates the dict; click handler `call utils.foo()` compiles to `(hs-method-call utils "foo")` which now dispatches through the new runtime fallback. Skip-list cleared of the 3 def entries. Suite hs-upstream-def: 24/27 → 27/27. Smoke 0-195 unchanged at 172/195.
-
-### 2026-04-25 — cluster 34 elsewhere / from-elsewhere modifier (+2)
-- **3044a168** — `HS: elsewhere / from elsewhere modifier (+2 tests)`. Three-part change: (a) `parser.sx` `parse-on-feat` parses an optional `elsewhere` (or `from elsewhere`) modifier between event-name and source. The `from elsewhere` variant uses a one-token lookahead so plain `from #target` keeps parsing as a source expression. Emits `:elsewhere true` part. (b) `compiler.sx` `scan-on` threads `elsewhere?` (10th param) through every recursive call + new `:elsewhere` cond branch. The dispatch case becomes a 3-way `cond` over target: elsewhere → `(dom-body)` (listener attaches to body and bubble sees every click), source → from-source, default → `me`. The `compiled-body` build is wrapped with `(when (not (host-call me "contains" (host-get event "target"))) BODY)` so handlers fire only on outside-of-`me` clicks. (c) Generator drops `supports "elsewhere" modifier` and `supports "from elsewhere" modifier` from `SKIP_TEST_NAMES`. Suite hs-upstream-on: 48/70 → 50/70. Smoke 0-195 unchanged at 172/195.
-
-### 2026-04-25 — cluster 34 count-filtered events + first modifier (+5 partial)
-- **19c97989** — `HS: count-filtered events + first modifier (+5 tests)`. Three-part change: (a) `parser.sx` `parse-on-feat` accepts `first` keyword before event-name (sets `cnt-min/max=1`), then optionally parses a count expression after event-name: bare number = exact count, `N to M` = inclusive range, `N and on` = unbounded above. Number tokens coerced via `parse-number`. New parts entry `:count-filter {"min" N "max" M-or--1}`. (b) `compiler.sx` `scan-on` gains a 9th `count-filter-info` param threaded through every recursive call + a new `:count-filter` cond branch. The handler binding now wraps the `(fn (event) BODY)` in `(let ((__hs-count 0)) (fn (event) (begin (set! __hs-count (+ __hs-count 1)) (when COUNT-CHECK BODY))))` when count info is present. Each `on EVENT N ...` clause produces its own closure-captured counter, so `on click 1` / `on click 2` / `on click 3` fire on their respective Nth click (mix-ranges test). (c) Generator drops 5 entries from `SKIP_TEST_NAMES` — `can filter events based on count`/`...count range`/`...unbounded count range`/`can mix ranges`/`on first click fires only once`. Suite hs-upstream-on: 43/70 → 48/70. Smoke 0-195 unchanged at 172/195. Remaining cluster-34 work (`elsewhere`/`from elsewhere`/`every`-keyword multi-handler) is independent from count filters and would need a separate iteration.
-
-### 2026-04-25 — cluster 29 hyperscript init events (+2 partial)
-- **e01a3baa** — `HS: hyperscript:before:init / :after:init events (+2 tests)`. `integration.sx` `hs-activate!` now wraps the activation block in `(when (dom-dispatch el "hyperscript:before:init" nil) ...)` — `dom-dispatch` builds a CustomEvent with `bubbles:true`, the mock El's `cancelable` defaults to true, `dispatchEvent` returns `!ev.defaultPrevented`, so `when` skips the activate body if a listener called `preventDefault()`. After activation completes successfully it dispatches `hyperscript:after:init`. Generator (`tests/playwright/generate-sx-tests.py`) gains two hand-rolled deftests: `fires hyperscript:before:init and hyperscript:after:init` builds a wa container, attaches listeners that append to a captured `events` list, sets innerHTML to a div with `_=`, calls `hs-boot-subtree!`, asserts the events list. `hyperscript:before:init can cancel initialization` attaches a preventDefault listener and asserts `data-hyperscript-powered` is absent on the inner div after boot. Suite hs-upstream-core/bootstrap: 20/26 → 22/26. Smoke 0-195: 170 → 172. Remaining 4 cluster-29 tests (basic parse error messages, parse-error event, EOF newline, eval-API throws on first error) all need stricter parser error-rejection plus a parse-error collector — recommend bucket-D plan-first multi-commit, not a single iteration.
-
-### 2026-04-25 — cluster 32 MutationObserver mock + on mutation dispatch (+7)
-- **13e02542** — `HS: MutationObserver mock + on mutation dispatch (+7 tests)`. Five-part change: (a) `parser.sx` `parse-on-feat` now consumes `of <FILTER>` after `mutation` event-name. FILTER is one of `attributes`/`childList`/`characterData` (ident tokens) or one or more `@name` attr-tokens chained by `or`. Emits `:of-filter {"type" T "attrs" L?}` part. (b) `compiler.sx` `scan-on` threads new `of-filter-info` param; the dispatch case becomes a `cond` over `event-name` — for `"mutation"` it emits `(do on-call (hs-on-mutation-attach! target MODE ATTRS))` where ATTRS is `(cons 'list attr-list)` so the list survives compile→eval. (c) `runtime.sx` `hs-on-mutation-attach!` builds a config dict (`attributes`/`childList`/`characterData`/`subtree`/`attributeFilter`) matched to mode, constructs a real `MutationObserver(cb)`, calls `mo.observe(target, opts)`, and the cb dispatches a `"mutation"` event on target. (d) `tests/hs-run-filtered.js` replaces the no-op MO with `HsMutationObserver` (global registry, decodes SX-list `attributeFilter`); prototype hooks on `El.setAttribute/appendChild/removeChild/_setInnerHTML` fire matching observers synchronously, with `__hsMutationActive` re-entry guard so handlers that mutate the DOM don't infinite-loop. Per-test reset clears registry + flag. (e) `generate-sx-tests.py` drops 7 mutation entries from `SKIP_TEST_NAMES` and adds two body patterns: `evaluate(() => document.querySelector(SEL).setAttribute(N,V))` → `(dom-set-attr ...)`, and `evaluate(() => document.querySelector(SEL).appendChild(document.createElement(T)))` → `(dom-append … (dom-create-element …))`. Suite hs-upstream-on: 36/70 → 43/70. Smoke 0-195 unchanged at 170/195.
-
-### 2026-04-25 — cluster 33 cookie API (partial +3)
-- No `.sx` edits needed — `set cookies.foo to 'bar'` already compiles to `(dom-set-prop cookies "foo" "bar")` which becomes `(host-set! cookies "foo" "bar")` once the `dom` module is loaded, and `cookies.foo` becomes `(host-get cookies "foo")`. So a JS-only Proxy + Python generator change does the trick. Two parts: (a) `tests/hs-run-filtered.js` adds a per-test `__hsCookieStore` Map, a `globalThis.cookies` Proxy with `length`/`clear`/named-key get traps and a set trap that writes the store, and a `Object.defineProperty(document, 'cookie', …)` getter/setter that reads and writes the same store (so the upstream `length is 0` test's pre-clear loop over `document.cookie` works). Per-test reset clears the store. (b) `tests/playwright/generate-sx-tests.py` declares `(define cookies (host-global "cookies"))` in the test header and emits hand-rolled deftests for the three tractable tests (`basic set`, `update`, `length is 0`). Suite hs-upstream-expressions/cookies: 0/5 → 3/5. Smoke 0-195 unchanged at 170/195. Remaining `basic clear` and `iterate` tests need runtime.sx edits (hs-method-call fallback + hs-for-each host-array recognition) — out of scope for a JS-only iteration.

-### 2026-04-25 — cluster 32 MutationObserver mock + on mutation dispatch (blocked)
-- Two issues conspire: (1) `loops/hs` worktree has no pre-built sx-tree binary so MCP tools aren't loaded, and the block-sx-edit hook prevents raw `Edit`/`Read`/`Write` on `.sx` files. Built `hosts/ocaml/_build/default/bin/mcp_tree.exe` via `dune build` this iteration but tools don't surface mid-session. (2) Cluster scope is genuinely big: parser must learn `on mutation of <filter>` (currently drops body after `of` — verified via compile dump: `on mutation of attributes put "Mutated" into me` → `(hs-on me "mutation" (fn (event) nil))`), compiler needs `:of-filter` plumbing similar to intersection's `:having`, runtime needs `hs-on-mutation-attach!`, JS runner mock needs a real MutationObserver (currently no-op `class{observe(){}disconnect(){}}` at hs-run-filtered.js:348) plus `setAttribute`/`appendChild` instrumentation, and 7 entries removed from `SKIP_TEST_NAMES`. Recommended next step: dedicated worktree where sx-tree loads at session start, multi-commit shape (parser → compiler+attach → mock+runner → generator skip-list).

-### 2026-04-25 — cluster 31 runtime null-safety error reporting (blocked)
-- All 18 tests are `SKIP (untranslated)` — generator has no `error("HS")` helper at all. Inspected representative compile outputs: `add .foo to #doesntExist` → `(for-each ... (hs-query-all "#doesntExist"))` (silently no-ops on empty list, no error); `hide #doesntExist` → `(hs-hide! (hs-query-all "#doesntExist") "display")` (likewise); `put 'foo' into #doesntExist` → `(hs-set-inner-html! (hs-query-first "#doesntExist") "foo")` (passes nil through); `x()` → `(x)` (raises `Undefined symbol: x`, wrong format); `x.y.z()` → `(hs-method-call (host-get x "y") "z")`. Implementing this requires generator helper + 17 compiler emit-path patches + function-call/method-call/possessive-base null guards + new `hs-named-target`/`hs-named-target-list` runtime — too many surfaces for a single-iteration commit. Bucket D explicitly says "plan-first" — recommended path is a dedicated design doc and multi-commit worktree like E36-E40, not a loop iteration.

 ### 2026-04-24 — cluster 29 hyperscript:before:init / :after:init / :parse-error (blocked)
 - **2b486976** — `HS-plan: mark cluster 29 blocked`. sx-tree MCP file ops returning `Yojson__Safe.Util.Type_error("Expected string, got null")` on every file-based call (sx_read_subtree, sx_find_all, sx_replace_by_pattern, sx_summarise, sx_pretty_print, sx_write_file). Only in-memory ops work (sx_eval, sx_build, sx_env). Without sx-tree I can't edit integration.sx to add before:init/after:init dispatch on hs-activate!. Investigated the 6 tests: 2 bootstrap (before/after init) need dispatchEvent wrapping activate; 4 parser tests require stricter parser error-rejection — `add - to` currently parses silently to `(set! nil (hs-add-to! (- 0 nil) nil))`, `on click blargh end on mouseenter also_bad` parses silently to `(do (hs-on me "click" (fn (event) blargh)) (hs-on me "mouseenter" (fn (event) also_bad)))`. Fundamental parser refactor is out of single-cluster budget regardless of sx-tree availability.

+- 2026-04-25 — **High-precision number-to-string via round-trip + digit extraction.** `js-big-int-str-loop` extracts decimal digits from integer-valued float. `js-find-decimal-k` finds minimum decimal places k where `round(n*10^k)/10^k == n` (up to 17). `js-format-decimal-digits` inserts decimal point. `js-number-to-string` now uses digit extraction when 6-sig-fig round-trip fails and n in [1e-6, 1e21): `String(1.0000001)="1.0000001"`, `String(1/3)="0.3333333333333333"`. String test262 subset: 58→62/100. 529/530 unit, 148/148 slice.
+
+- 2026-04-25 — **String wrapper objects + number-to-string sci notation.** `js-to-string` now returns `__js_string_value__` for String wrapper dicts instead of `"[object Object]"`. `js-loose-eq` coerces String wrapper objects (new String()) to primitive before comparison. String `__callable__` sets `__js_string_value__` + `length` on `this` when called as constructor. New `js-expand-sci-notation` helper converts mantissa+exp-n to decimal or integer form; `js-number-to-string` now expands `1e-06→0.000001`, `1e+06→1000000`, fixes `1e21→1e+21`. String test262 subset: 45→58/100. 529/530 unit, 148/148 slice.
+
+- 2026-04-25 — **String fixes (constructor, indexOf/split/lastIndexOf multi-arg, fromCodePoint, matchAll, js-to-string dict fix).** Added `String.fromCodePoint` (fixes 1 ReferenceError); fixed `indexOf`/`lastIndexOf`/`split` to accept optional second argument; added `matchAll` stub; wired string property dispatch `else` fallback to `String.prototype` (fixes `'a'.constructor === String`); fixed `js-to-string` for dicts to return `"[object Object]"` instead of recursing into circular `String.prototype.constructor` structure. Scoreboard: String 42→43, timeouts 32→13. Total 162→202/300 (54%→67.3%). 529/530 unit, 148/148 slice.
+
+- 2026-04-25 — **Number/String wrapper constructor-detection fix + Array.prototype.toString + js-to-number for wrappers + `>>>` operator.** `Number.__callable__` and `String.__callable__` now check `this.__proto__ === Number/String.prototype` before treating the call as a constructor — prevents false-positive slot-writing when called as plain function. `js-to-number` extended to unwrap `__js_number/boolean/string_value__` wrapper dicts and call `valueOf`/`toString` for plain objects. `Array.prototype.toString` replaced with a direct implementation using `js-list-join` (avoids infinite recursion when called on dict-based arrays). `>>>` (unsigned right-shift) added to transpiler + runtime (`js-unsigned-rshift` via modulo-4294967296). String test262 subset: 62→66/100. 529/530 unit, 147/148 slice.
+
+- 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`.

 - 2026-04-23 — scaffold landed: lib/js/{lexer,parser,transpile,runtime}.sx stubs + test.sh. 7/7 smoke tests pass (js-tokenize/js-parse/js-transpile stubs + js-to-boolean coercion cases).
 - 2026-04-23 — Phase 1 (Lexer) complete: numbers (int/float/hex/exp/leading-dot), strings (escapes), idents/keywords, punctuation, all operators (1-4 char, longest-match), // and /* */ comments. 38/38 tests pass. Gotchas found: `peek` and `emit!` are primitives (shadowed to `js-peek`, `js-emit!`); `cond` clauses take ONE body only, multi-expr needs `(do ...)` wrapper.
 - 2026-04-23 — Phase 2 (Pratt expression parser) complete: literals, binary precedence (w/ `**` right-assoc), unary (`- + ! ~ typeof void`), member access (`.`/`[]`), call chains, array/object literals (ident+string+number keys), ternary, arrow fns (zero/one/many params; curried), assignment (right-assoc incl. compound `+=` etc.). AST node shapes all match the `js-*` names already wired. 47 new tests, 85/85 total. Most of the Phase 2 scaffolding was already written in an earlier session — this iteration verified every path, added the parser test suite, and greened everything on the first pass. No new gotchas beyond Phase 1.
