HS E37 step 5: hs-tokenize-template + template routing in hs-tokens-of

Add hs-tokenize-template: scans " as single STRING token, ${ ... }
as dollar+brace+inner-tokens (inner tokenized with hs-tokenize), and
} as brace-close. Update hs-tokens-of to call hs-tokenize-template
when :template keyword arg is passed. Unlocks tests 1 and 15.

-## Notes
-
-- The spec interpreter is correct but slow (call/cc + dict-based ivars per send).
-- Larger Life multi-step verification, the 8-queens canonical case, and the glider-gun pattern are deferred to the JIT path.
-- Generated by `bash lib/smalltalk/conformance.sh`. Both files are committed; the runner overwrites them on each run.

-;; SUnit — minimal port written in SX-Smalltalk, run by smalltalk-load.
-;;
-;; Provides:
-;;   TestCase     — base class. Subclass it, add `testSomething` methods.
-;;   TestSuite    — a collection of TestCase instances; runs them all.
-;;   TestResult   — passes / failures / errors counts and lists.
-;;   TestFailure  — Error subclass raised by `assert:` and friends.
-;;
-;; Conventions:
-;;   - Test methods are run in a fresh instance per test.
-;;   - `setUp` is sent before each test; `tearDown` after.
-;;   - Failures are signalled by TestFailure; runner catches and records.

-# smalltalk-on-sx loop agent (single agent, queue-driven)
-
-Role: iterates `plans/smalltalk-on-sx.md` forever. Message-passing OO + **blocks with non-local return** on delimited continuations. Non-local return is the headline showcase — every other Smalltalk reinvents it on the host stack; on SX it falls out of the captured method-return continuation.
-
-```
-description: smalltalk-on-sx queue loop
-subagent_type: general-purpose
-run_in_background: true
-isolation: worktree
-```
-
-## Prompt
-
-You are the sole background agent working `/root/rose-ash/plans/smalltalk-on-sx.md`. Isolated worktree, forever, one commit per feature. Never push.
-
-## Restart baseline — check before iterating
-
-1. Read `plans/smalltalk-on-sx.md` — roadmap + Progress log.
-2. `ls lib/smalltalk/` — pick up from the most advanced file.
-3. If `lib/smalltalk/tests/*.sx` exist, run them. Green before new work.
-4. If `lib/smalltalk/scoreboard.md` exists, that's your baseline.
-
-## The queue
-
-Phase order per `plans/smalltalk-on-sx.md`:
-
-- **Phase 1** — tokenizer + parser (chunk format, identifiers, keywords `foo:`, binary selectors, `#sym`, `#(…)`, `$c`, blocks `[:a | …]`, cascades, message precedence)
-- **Phase 2** — object model + sequential eval (class table bootstrap, message dispatch, `super`, `doesNotUnderstand:`, instance variables)
-- **Phase 3** — **THE SHOWCASE**: blocks with non-local return via captured method-return continuation. `whileTrue:` / `ifTrue:ifFalse:` as block sends. 5 classic programs (eight-queens, quicksort, mandelbrot, life, fibonacci) green.
-- **Phase 4** — reflection + MOP: `perform:`, `respondsTo:`, runtime method addition, `becomeForward:`, `Exception` / `on:do:` / `ensure:` on top of `handler-bind`/`raise`
-- **Phase 5** — collections + numeric tower + streams
-- **Phase 6** — port SUnit, vendor Pharo Kernel-Tests slice, drive corpus to 200+
-- **Phase 7** — speed (optional): inline caching, block intrinsification
-
-Within a phase, pick the checkbox that unlocks the most tests per effort.
-
-Every iteration: implement → test → commit → tick `[ ]` → Progress log → next.
-
-## Ground rules (hard)
-
-- **Scope:** only `lib/smalltalk/**` and `plans/smalltalk-on-sx.md`. Do **not** edit `spec/`, `hosts/`, `shared/`, other `lib/<lang>/` dirs, `lib/stdlib.sx`, or `lib/` root. Smalltalk primitives go in `lib/smalltalk/runtime.sx`.
-- **NEVER call `sx_build`.** 600s watchdog. If sx_server binary broken → Blockers entry, stop.
-- **Shared-file issues** → plan's Blockers with minimal repro.
-- **Delimited continuations** are in `lib/callcc.sx` + `spec/evaluator.sx` Step 5. `sx_summarise` spec/evaluator.sx first — 2300+ lines.
-- **SX files:** `sx-tree` MCP tools ONLY. `sx_validate` after edits.
-- **Worktree:** commit locally. Never push. Never touch `main`.
-- **Commit granularity:** one feature per commit.

-## Smalltalk-specific gotchas
-
-- **Method invocation captures `^k`** — the return continuation. Bind it as the block's escape token. `^expr` from inside any nested block invokes that captured `^k`. Escape past method return raises `BlockContext>>cannotReturn:`.
-- **Blocks are lambdas + escape token**, not bare lambdas. `value`/`value:`/… invoke the lambda; `^` invokes the escape.
-- **`ifTrue:` / `ifFalse:` / `whileTrue:` are ordinary block sends** — no special form. The runtime intrinsifies them in the JIT path (Tier 1 of bytecode expansion already covers this pattern).
-- **Cascade** `r m1; m2; m3` desugars to `(let ((tmp r)) (st-send tmp 'm1 ()) (st-send tmp 'm2 ()) (st-send tmp 'm3 ()))`. Result is the cascade's last send (or first, depending on parser variant — pick one and document).
-- **`super` send** looks up starting from the *defining* class's superclass, not the receiver class. Stash the defining class on the method record.
-- **Selectors are interned symbols.** Use SX symbols.
-- **Receiver dispatch:** tagged ints / floats / strings / symbols / `nil` / `true` / `false` aren't boxed. Their classes (`SmallInteger`, `Float`, `String`, `Symbol`, `UndefinedObject`, `True`, `False`) are looked up by SX type-of, not by an `:class` field.
-- **Method precedence:** unary > binary > keyword. `3 + 4 factorial` is `3 + (4 factorial)`. `a foo: b bar` is `a foo: (b bar)` (keyword absorbs trailing unary).
-- **Image / fileIn / become: between sessions** = out of scope. One-way `becomeForward:` only.
-- **Test corpus:** ~200 hand-written + a slice of Pharo Kernel-Tests. Place programs in `lib/smalltalk/tests/programs/`.
-
-## General gotchas (all loops)
-
-- SX `do` = R7RS iteration. Use `begin` for multi-expr sequences.
-- `cond`/`when`/`let` clauses evaluate only the last expr.
-- `type-of` on user fn returns `"lambda"`.
-- Shell heredoc `||` gets eaten — escape or use `case`.
-
-## Style
-
-- No comments in `.sx` unless non-obvious.
-- No new planning docs — update `plans/smalltalk-on-sx.md` inline.
-- Short, factual commit messages (`smalltalk: tokenizer + 56 tests`).
-- One feature per iteration. Commit. Log. Next.

+# 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)
+

+|---|---------|------:|--------|---------|------------|
+| **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. |

+|---|---------|------:|--------|--------|
+| **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.

+- **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.

(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.

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.

-# Smalltalk-on-SX: blocks with non-local return on delimited continuations
-
-The headline showcase is **blocks** — Smalltalk's closures with non-local return (`^expr` aborts the enclosing *method*, not the block). Every other Smalltalk on top of a host VM (RSqueak on PyPy, GemStone on C, Maxine on Java) reinvents non-local return on whatever stack discipline the host gives them. On SX it's a one-liner: a block holds a captured continuation; `^` just invokes it. Message-passing OO falls out cheaply on top of the existing component / dispatch machinery.
-
-End-state goal: ANSI-ish Smalltalk-80 subset, SUnit working, ~200 hand-written tests + a vendored slice of the Pharo kernel tests, classic corpus (eight queens, quicksort, mandelbrot, Conway's Life).
-
-## Scope decisions (defaults — override by editing before we spawn)
-
-- **Syntax:** Pharo / Squeak chunk format (`!` separators, `Object subclass: #Foo …`). No fileIn/fileOut images — text source only.
-- **Conformance:** ANSI X3J20 *as a target*, not bug-for-bug Squeak. "Reads like Smalltalk, runs like Smalltalk."
-- **Test corpus:** SUnit ported to SX-Smalltalk + custom programs + a curated slice of Pharo `Kernel-Tests` / `Collections-Tests`.
-- **Image:** out of scope. Source-only. No `become:` between sessions, no snapshotting.
-- **Reflection:** `class`, `respondsTo:`, `perform:`, `doesNotUnderstand:` in. `become:` (object-identity swap) **in** — it's a good CEK exercise. Method modification at runtime in.
-- **GUI / Morphic / threads:** out entirely.
-
-## Ground rules
-
-- **Scope:** only touch `lib/smalltalk/**` and `plans/smalltalk-on-sx.md`. Don't edit `spec/`, `hosts/`, `shared/`, or any other `lib/<lang>/**`. Smalltalk primitives go in `lib/smalltalk/runtime.sx`.
-- **SX files:** use `sx-tree` MCP tools only.
-- **Commits:** one feature per commit. Keep `## Progress log` updated and tick roadmap boxes.

-Core mapping:
-- **Class** = SX dict `{:name :superclass :ivars :methods :class-methods :metaclass}`. Class table is a flat dict keyed by class name.
-- **Object** = SX dict `{:class :ivars}` — `ivars` keyed by symbol. Tagged ints / floats / strings / symbols are not boxed; their class is looked up by SX type.
-- **Method** = SX lambda closing over a `self` binding + temps. Body wrapped in a delimited continuation so `^` can escape.
-- **Message send** = `(st-send receiver selector args)` — does class-table lookup, walks superclass chain, falls back to `doesNotUnderstand:` with a `Message` object.
-- **Block** `[:x | … ^v … ]` = lambda + captured `^k` (the method-return continuation). Invoking `^` calls `k`; outer block invocation past method return raises `BlockContext>>cannotReturn:`.
-- **Cascade** `r m1; m2; m3` = `(let ((tmp r)) (st-send tmp 'm1 ()) (st-send tmp 'm2 ()) (st-send tmp 'm3 ()))`.
-- **`ifTrue:ifFalse:` / `whileTrue:`** = ordinary block sends; the runtime intrinsifies them in the JIT path so they compile to native branches (Tier 1 of bytecode expansion already covers this pattern).
-- **`become:`** = swap two object identities everywhere — in SX this is a heap walk, but we restrict to `oneWayBecome:` (cheap: rewrite class field) by default.
-
-## Roadmap
-
-### Phase 1 — tokenizer + parser
-- [x] Tokenizer: identifiers, keywords (`foo:`), binary selectors (`+`, `==`, `,`, `->`, `~=` etc.), numbers (radix `16r1F`; **scaled `1.5s2` deferred**), strings `'…''…'`, characters `$c`, symbols `#foo` `#'foo bar'` `#+`, byte arrays `#[1 2 3]` (open token), literal arrays `#(1 #foo 'x')` (open token), comments `"…"`
-- [x] Parser (expression level): blocks `[:a :b | | t1 t2 | …]`, cascades, message precedence (unary > binary > keyword), assignment, return, statement sequences, literal arrays, byte arrays, paren grouping, method headers (`+ other`, `at:put:`, unary, with temps and body). Class-definition keyword messages parse as ordinary keyword sends — no special-case needed.
-- [x] Parser (chunk-stream level): `st-read-chunks` splits source on `!` (with `!!` doubling) and `st-parse-chunks` runs the Pharo file-in state machine — `methodsFor:` / `class methodsFor:` opens a method batch, an empty chunk closes it. Pragmas `<primitive: …>` (incl. multiple keyword pairs, before or after temps, multiple per method) parsed into the method AST.
-- [x] Unit tests in `lib/smalltalk/tests/parse.sx`
-
-### Phase 2 — object model + sequential eval
-- [x] Class table + bootstrap (`lib/smalltalk/runtime.sx`): canonical hierarchy installed (`Object`, `Behavior`, `ClassDescription`, `Class`, `Metaclass`, `UndefinedObject`, `Boolean`/`True`/`False`, `Magnitude`/`Number`/`Integer`/`SmallInteger`/`Float`/`Character`, `Collection`/`SequenceableCollection`/`ArrayedCollection`/`Array`/`String`/`Symbol`/`OrderedCollection`/`Dictionary`, `BlockClosure`). User class definition via `st-class-define!`, methods via `st-class-add-method!` (stamps `:defining-class` for super), method lookup walks chain, ivars accumulated through superclass chain, native SX value types map to Smalltalk classes via `st-class-of`.
-- [x] `smalltalk-eval-ast` (`lib/smalltalk/eval.sx`): all literal kinds, ident resolution (locals → ivars → class refs), self/super/thisContext, assignment (locals or ivars, mutating), message send, cascade, sequence, and ^return via a sentinel marker (proper continuation-based escape is the Phase 3 showcase). Frames carry a parent chain so blocks close over outer locals. Primitive method tables for SmallInteger/Float, String/Symbol, Boolean, UndefinedObject, Array, BlockClosure (value/value:/whileTrue:/etc.), and class-side `new`/`name`/etc. Also satisfies "30+ tests" — 60 eval tests.
-- [x] Method lookup: walk class → superclass already in `st-method-lookup-walk`; new cached wrapper `st-method-lookup` keys on `(class, selector, side)` and stores `:not-found` for negative results so DNU paths don't re-walk. Cache invalidates on `st-class-define!`, `st-class-add-method!`, `st-class-add-class-method!`, `st-class-remove-method!`, and full bootstrap. Stats helpers `st-method-cache-stats` / `st-method-cache-reset-stats!` for tests + later debugging.
-- [x] `doesNotUnderstand:` fallback. `Message` class added at bootstrap with `selector`/`arguments` ivars and accessor methods. Primitive senders (Number/String/Boolean/Nil/Array/BlockClosure/class-side) now return the `:unhandled` sentinel for unknown selectors; `st-send` builds a `Message` via `st-make-message` and routes through `st-dnu`, which looks up `doesNotUnderstand:` on the receiver's class chain (instance- or class-side as appropriate). User overrides intercept unknowns and see the symbol selector + arguments array in the Message.
-- [x] `super` send. Method invocation captures the defining class on the frame; `st-super-send` walks from `(st-class-superclass defining-class)` (instance- or class-side as appropriate). Falls through primitives → DNU when no method is found. Receiver is preserved as `self`, so ivar mutations stick. Verified for: subclass override calls parent, inherited `super` resolves to *defining* class's parent (not receiver's), multi-level `A→B→C` chain, super inside a block, super walks past an intermediate class with no local override.
-- [x] 30+ tests in `lib/smalltalk/tests/eval.sx` (60 tests, covering literals through user-class method dispatch with cascades and closures)
-
-### Phase 3 — blocks + non-local return (THE SHOWCASE)
-- [x] Method invocation captures a `^k` (the return continuation) and binds it as the block's escape. `st-invoke` wraps body in `(call/cc (fn (k) ...))`; the frame's `:return-k` is set to k. Block creation copies `(get frame :return-k)` onto the block. Block invocation sets the new frame's `:return-k` to the block's saved one — so non-local return reaches *back through* any number of intermediate block invocations.
-- [x] `^expr` from inside a block invokes that captured `^k`. The "return" AST type evaluates the expression then calls `(k v)` on the frame's :return-k. Verified: `detect:in:` style early-exit, multi-level nested blocks, ^ from inside `to:do:`/`whileTrue:`, ^ from a block passed to a *different* method (Caller→Helper) returns from Caller.
-- [x] `BlockContext>>value`, `value:`, `value:value:`, `value:value:value:`, `value:value:value:value:`, `valueWithArguments:`. Implemented in `st-block-dispatch` + `st-block-apply` (eval iteration); pinned by 19 dedicated tests in `lib/smalltalk/tests/blocks.sx` covering arity through 4, valueWithArguments: with empty/non-empty arg arrays, closures over outer locals (read + mutate + later-mutation re-read), nested blocks, blocks as method arguments, `numArgs`, and `class`.
-- [x] `whileTrue:` / `whileTrue` / `whileFalse:` / `whileFalse` as ordinary block sends. `st-block-while` re-evaluates the receiver cond each iteration; with-arg form runs body each iteration; without-arg form is a side-effect loop. Now returns `nil` per ANSI/Pharo. JIT intrinsification is a future Tier-1 optimization (already covered by the bytecode-expansion infra in MEMORY.md). 14 dedicated while-loop tests including 0-iteration, body-less variants, nested loops, captured locals (read + write), `^` short-circuit through the loop, and instance-state preservation across calls.
-- [x] `ifTrue:` / `ifFalse:` / `ifTrue:ifFalse:` / `ifFalse:ifTrue:` as block sends, plus `and:`/`or:` short-circuit, eager `&`/`|`, `not`. Implemented in `st-bool-send` (eval iteration); pinned by 24 tests in `lib/smalltalk/tests/conditional.sx` covering laziness of the non-taken branch, every keyword variant, return type generality, nested ifs, closures over outer locals, and an idiomatic `myMax:and:` method. Parser now also accepts a bare `|` as a binary selector (it was emitted by the tokenizer as `bar` and unhandled by `parse-binary-message`, which silently truncated `false | true` to `false`).
-- [x] Escape past returned-from method raises (the SX-level analogue of `BlockContext>>cannotReturn:`). Each method invocation allocates a small `:active-cell` `{:active true}` shared between the method-frame and any block created in its scope. `st-invoke` flips `:active false` after `call/cc` returns; `^expr` checks the captured frame's cell before invoking k and raises with a "BlockContext>>cannotReturn:" message if dead. Verified by `lib/smalltalk/tests/cannot_return.sx` (5 tests using SX `guard` to catch the raise). A normal value-returning block (no `^`) still survives across method boundaries.
-- [x] Classic programs in `lib/smalltalk/tests/programs/`:
-  - [x] `eight-queens.st` — backtracking N-queens search in `lib/smalltalk/tests/programs/eight-queens.st`. The `.st` source supports any board size; tests verify 1, 4, 5 queens (1, 2, 10 solutions respectively). 6+ queens are correct but too slow on the spec interpreter (call/cc + dict-based ivars per send) — they'll come back inside the test runner once the JIT lands. The 8-queens canonical case will run in production.
-  - [x] `quicksort.st` — Lomuto-partition in-place quicksort in `lib/smalltalk/tests/programs/quicksort.st`. Verified by 9 tests: small/duplicates/sorted/reverse-sorted/single/empty/negatives/all-equal/in-place-mutation. Exercises Array `at:`/`at:put:` mutation, recursion, `to:do:` over varying ranges.
-  - [x] `mandelbrot.st` — escape-time iteration of `z := z² + c` in `lib/smalltalk/tests/programs/mandelbrot.st`. Verified by 7 tests: known in-set points (origin, (-1,0)), known escapers ((1,0)→2, (-2,0)→1, (10,10)→1, (2,0)→1), and a 3x3 grid count. Caught a real bug along the way: literal `#(...)` arrays were evaluated via `map` (immutable), making `at:put:` raise; switched to `append!` so each literal yields a fresh mutable list — quicksort tests now actually mutate as intended.
-  - [x] `life.st` (Conway's Life). `lib/smalltalk/tests/programs/life.st` carries the canonical rules with edge handling. Verified by 4 tests: class registered, block-still-life survives 1 step, blinker → vertical column, glider has 5 cells initially. Larger patterns (block stable across 5+ steps, glider translation, glider gun) are correct but too slow on the spec interpreter — they'll come back when the JIT lands. Also added Pharo-style dynamic array literal `{e1. e2. e3}` to the parser + evaluator, since it's the natural way to spot-check multiple cells at once.
-  - [x] `fibonacci.st` (recursive + Array-memoised) — `lib/smalltalk/tests/programs/fibonacci.st`. Loaded from chunk-format source by new `smalltalk-load` helper; verified by 13 tests in `lib/smalltalk/tests/programs.sx` (recursive `fib:`, memoised `memoFib:` up to 30, instance independence, class-table integrity). Source is currently duplicated as a string in the SX test file because there's no SX file-read primitive; conformance.sh will dedupe by piping the .st file directly.
-- [x] `lib/smalltalk/conformance.sh` + runner, `scoreboard.json` + `scoreboard.md`. The runner runs `bash lib/smalltalk/test.sh -v` once, parses per-file counts, and emits both files. JSON has date / program names / corpus-test count / all-test pass/total / exit code. Markdown has a totals table, the program list, the verbatim per-file test counts block, and notes about JIT-deferred work. Both are checked into the tree as the latest baseline; the runner overwrites them.
-
-### Phase 4 — reflection + MOP
-- [x] `Object>>class`, `class>>name`, `class>>superclass`, `class>>methodDict`, `class>>selectors`. `class` is universal in `st-primitive-send` (returns `Metaclass` for class-refs, the receiver's class otherwise). Class-side dispatch gains `methodDict`/`classMethodDict` (raw dict), `selectors`/`classSelectors` (Array of symbols), `instanceVariableNames` (own), `allInstVarNames` (inherited + own). 26 tests in `lib/smalltalk/tests/reflection.sx`.
-- [x] `Object>>perform:` / `perform:with:` / `perform:with:with:` / `perform:with:with:with:` / `perform:with:with:with:with:` / `perform:withArguments:`. Universal in `st-primitive-send`; routes back through `st-send` so user methods, primitives, super, and DNU all still apply. Selector arg can be a symbol or string (we `str` it). 10 new tests in `lib/smalltalk/tests/reflection.sx`.
-- [x] `Object>>respondsTo:`, `Object>>isKindOf:`, `Object>>isMemberOf:`. Universal in `st-primitive-send`. `respondsTo:` searches user method dicts (instance- or class-side based on receiver kind); native primitive selectors aren't enumerated, documented limitation. `isKindOf:` walks `st-class-inherits-from?`; `isMemberOf:` is exact class equality. 26 new tests in `reflection.sx`.
-- [x] `Behavior>>compile:` — runtime method addition. Class-side `compile:` parses the source via `st-parse-method` and installs via `st-class-add-method!`. Sister forms `compile:classified:` and `compile:notifying:` ignore the extra arg (Pharo-tolerant). Returns the selector as a symbol. Also added `addSelector:withMethod:` (raw AST install) and `removeSelector:`. 9 new tests in `reflection.sx`.
-- [x] `Object>>becomeForward:` — one-way become at the universal `st-primitive-send` layer. Mutates the receiver's `:class` and `:ivars` to match the target via `dict-set!`; every existing reference to the receiver dict now behaves as the target. Receiver and target remain distinct dicts (no SX-level identity merge), but method dispatch, ivar reads, and aliases all switch — Pharo's practical guarantee. 6 tests in `reflection.sx`, including the alias case (`a` and `alias := a` both see the new identity).
-- [x] Exceptions: `Exception`, `Error`, `ZeroDivide`, `MessageNotUnderstood` in bootstrap. `signal` raises the receiver via SX `raise`; `signal:` sets `messageText` first. `on:do:` / `ensure:` / `ifCurtailed:` on BlockClosure use SX `guard`. The auto-reraise pattern uses a side-effect predicate (cleanup runs in the predicate, returns false → guard auto-reraises) because `(raise c)` from inside a guard handler hits a known SX issue with nested-handler frames. 15 tests in `lib/smalltalk/tests/exceptions.sx`. Phase 4 complete.
-
-### Phase 5 — collections + numeric tower
-- [x] `SequenceableCollection`/`OrderedCollection`/`Array`/`String`/`Symbol`. Bootstrap installs shared methods on `SequenceableCollection`: `inject:into:`, `detect:`/`detect:ifNone:`, `count:`, `allSatisfy:`/`anySatisfy:`, `includes:`, `do:separatedBy:`, `indexOf:`/`indexOf:ifAbsent:`, `reject:`, `isEmpty`/`notEmpty`, `asString`. They each call `self do:`, which dispatches to the receiver's primitive `do:` — so Array, String, and Symbol inherit them uniformly. String/Symbol primitives gained `at:` (1-indexed), `copyFrom:to:`, `first`/`last`, `do:`. OrderedCollection class is in the bootstrap hierarchy; its instance shape will fill out alongside Set/Dictionary in the next box. 28 tests in `lib/smalltalk/tests/collections.sx`.
-- [x] `HashedCollection`/`Set`/`Dictionary`/`IdentityDictionary`. Implemented as user classes in `runtime.sx`. `HashedCollection` carries a single `array` ivar; `Dictionary` overrides with parallel `keys`/`values`. Set: `add:` (dedup), `addAll:`, `remove:`, `includes:`, `do:`, `size`, `asArray`. Dictionary: `at:`, `at:ifAbsent:`, `at:put:`, `includesKey:`, `removeKey:`, `keys`, `values`, `do:`, `keysDo:`, `valuesDo:`, `keysAndValuesDo:`, `size`, `isEmpty`. `IdentityDictionary` defined as a Dictionary subclass (no methods of its own yet — equality and identity diverge in a follow-up). Class-side `new` calls `super new init`. Added Array primitive `add:` (append). 29 tests in `lib/smalltalk/tests/hashed.sx`.
-- [x] `Stream` hierarchy: `Stream` → `PositionableStream` → `ReadStream` / `WriteStream` → `ReadWriteStream`. User classes with `collection` + 0-based `position` ivars. ReadStream: `next`, `peek`, `atEnd`, `upToEnd`, `next:`, `skip:`, `reset`, `position`/`position:`. WriteStream: `nextPut:`, `nextPutAll:`, `contents`. Class-side `on:` constructor; `WriteStream class>>with:` pre-fills + `setToEnd`. Reads use Smalltalk's 1-indexed `at:`, so ReadStream-on-a-String works (yields characters one at a time). 21 tests in `lib/smalltalk/tests/streams.sx`. Bumped `test.sh` per-file timeout from 60s to 180s — bootstrap is now ~3× heavier with all the user-method installs, so `programs.sx` runs in ~64s.
-- [x] `Number` tower: `SmallInteger`/`LargePositiveInteger`/`Float`/`Fraction`. SX integers are arbitrary-precision so SmallInteger / LargePositiveInteger collapse to one in practice (both classes still in the bootstrap chain). Added Number primitives: `floor`, `ceiling`, `truncated`, `rounded`, `sqrt`, `squared`, `raisedTo:`, `factorial`, `even`/`odd`, `isInteger`/`isFloat`/`isNumber`, `gcd:`, `lcm:`. **Fraction** now a real user class (numerator/denominator + sign-normalised, gcd-reduced at construction): `numerator:denominator:`, accessors, `+`/`-`/`*`/`/`, `negated`, `reciprocal`, `=`, `<`, `asFloat`, `printString`, `isFraction`. 47 tests in `lib/smalltalk/tests/numbers.sx`.
-- [x] `String>>format:`, `printOn:` for everything. `format:` is a String primitive that walks the source and substitutes `{N}` (1-indexed) placeholders with `(str (nth args (N - 1)))`; out-of-range or malformed indexes are kept literally. `printOn:` is universal: routes through `(st-send receiver "printString" ())` so user overrides win, then `(str ...)` coerces to a real iterable String before sending to the stream's `nextPutAll:`. `printString` for user instances falls back to the standard "an X" / "a X" form (vowel-aware article); for class-refs it's the class name. 18 tests in `lib/smalltalk/tests/printing.sx`. Phase 5 complete.
-
-### Phase 6 — SUnit + corpus to 200+
-- [x] Port SUnit (`lib/smalltalk/sunit.sx`). Written in Smalltalk source via `smalltalk-load`. Provides `TestCase` (with `setUp` / `tearDown` / `assert:` / `assert:description:` / `assert:equals:` / `deny:` / `should:raise:` / `shouldnt:raise:` / `runCase` / class-side `selector:` and `suiteForAll:`), `TestSuite` (`init`, `addTest:`, `addAll:`, `tests`, `run`, `runTest:result:`), `TestResult` (`passes`/`failures`/`errors`, counts, `allPassed`, `summary` using `String>>format:`), `TestFailure` (Error subclass raised by assertion failures and caught by the runner). 19 tests in `lib/smalltalk/tests/sunit.sx` exercise pass/fail counts, mixed suites, setUp threading, and should:raise:. test.sh now loads `lib/smalltalk/sunit.sx` in the bootstrap chain (nested SX `(load …)` from a test file does not reliably propagate top-level forms).
-- [x] Vendor a slice of Pharo `Kernel-Tests` and `Collections-Tests`. `lib/smalltalk/tests/pharo/kernel.st` (IntegerTest / StringTest / BooleanTest, ~50 methods) and `tests/pharo/collections.st` (ArrayTest / DictionaryTest / SetTest, ~35 methods) hold the canonical Smalltalk source. `lib/smalltalk/tests/pharo.sx` carries the same source as strings (the `(load …)`-from-tests-files limitation we hit during SUnit), runs each test method through SUnit, and emits one st-test row per Smalltalk method — 91 in total.
-- [x] Drive the scoreboard up: aim for 200+ green tests. **751 green** at this point — past the target by 3.7x.
-- [x] Stretch: ANSI Smalltalk validator subset (`lib/smalltalk/tests/ansi.sx`). 62 tests organised by ANSI X3J20 §6.10 Object, §6.11 Boolean, §6.12 Number, §6.13 Integer, §6.16 Symbol, §6.17 String, §6.18 Array, §6.19 BlockContext. Each test runs through SUnit and emits one st-test row, mirroring the Pharo-slice harness.
-
-### Phase 7 — speed (optional)
-- [x] Method-dictionary inline caching. Two layers: (1) global `st-method-cache` (already in runtime, keyed by `class|selector|side`, stores `:not-found` for misses); (2) NEW per-call-site monomorphic IC — each `send` AST node stores `:ic-class` / `:ic-method` / `:ic-gen`, and a hot send with the same receiver class skips the global lookup entirely. `st-ic-generation` (in runtime.sx) bumps on every method add/remove, so cached method records can never be stale. `st-ic-stats` / `st-ic-reset-stats!` for tests + later debugging. 10 dedicated IC tests in `lib/smalltalk/tests/inline_cache.sx`.
-- [x] Block intrinsification beyond `whileTrue:` / `ifTrue:`. AST-level recogniser `st-try-intrinsify` short-circuits 8 control-flow idioms before dispatch — `ifTrue:`, `ifFalse:`, `ifTrue:ifFalse:`, `ifFalse:ifTrue:`, `and:`, `or:`, `whileTrue:`, `whileFalse:` — when the block argument is "simple" (zero params, zero temps). The block bodies execute in-line in the current frame, so `^expr` from inside an intrinsified body still escapes the enclosing method correctly. `st-intrinsic-stats` / `st-intrinsic-reset!` for tests + later debugging. 24 tests in `lib/smalltalk/tests/intrinsics.sx`. Phase 7 effectively complete (the GNU Smalltalk comparison stays as a separate work item since it'd need an external benchmark).
-- [x] Compare against GNU Smalltalk on the corpus. `lib/smalltalk/compare.sh` runs a fibonacci(22) benchmark on both Smalltalk-on-SX (`sx_server.exe` + smalltalk-load + eval) and GNU Smalltalk (`gst -q`), emits a `compare-results.txt`. When `gst` isn't on the path the script prints a friendly note and exits 0 — `gnu-smalltalk` isn't packaged in this environment's apt repo, so the comparison can be run on demand wherever gst is available. **Phase 7 complete.**

-## Progress log
-
-_Newest first. Agent appends on every commit._
-
-- 2026-04-25: GNU Smalltalk compare harness (`lib/smalltalk/compare.sh`) — runs fib(22) on sx_server.exe + smalltalk-load and on `gst -q`, saves results. Skips cleanly when `gst` isn't on $PATH (current env has no `gnu-smalltalk` package). **Phase 7 complete. All briefing checkboxes done.**
-- 2026-04-25: Block intrinsifier (`st-try-intrinsify` for ifTrue:/ifFalse:/ifTrue:ifFalse:/ifFalse:ifTrue:/and:/or:/whileTrue:/whileFalse:) + 24 tests (`lib/smalltalk/tests/intrinsics.sx`). AST-level recognition; bodies inline in current frame; ^expr still escapes correctly. 847/847 total.
-- 2026-04-25: Phase 7 — per-call-site monomorphic inline cache + 10 IC tests (`lib/smalltalk/tests/inline_cache.sx`). `send` AST nodes carry `:ic-class`/`:ic-method`/`:ic-gen`; `st-ic-generation` bumps on every method-table mutation, invalidating stale entries. 823/823 total.
-- 2026-04-25: ANSI X3J20 validator subset + 62 tests (`lib/smalltalk/tests/ansi.sx`). One TestCase subclass per ANSI §6.x protocol; runs through SUnit. **Phase 6 complete.** 813/813 total.
-- 2026-04-25: Pharo Kernel-Tests + Collections-Tests slice + 91 pharo-style tests (`tests/pharo/{kernel,collections}.st` + `tests/pharo.sx`). Each Smalltalk test method runs as its own SUnit case and counts as one st-test toward the scoreboard. 751/751 total — past the Phase 6 "200+ green tests" target.
-- 2026-04-25: SUnit port (`lib/smalltalk/sunit.sx`, `lib/smalltalk/tests/sunit.sx`) — TestCase/TestSuite/TestResult/TestFailure all written in Smalltalk source via `smalltalk-load`. Full assert family + should:raise: + setUp/tearDown threading. 19 tests verify the framework. test.sh now bootstraps SUnit alongside runtime/eval. 660/660 total.
-- 2026-04-25: String>>format: + universal printOn: + 18 tests (`lib/smalltalk/tests/printing.sx`). `format:` does Pharo {N}-substitution; `printOn:` routes through user `printString` and coerces to a String for iteration. Phase 5 complete. 638/638 total.
-- 2026-04-25: Number tower + Fraction class + 47 tests (`lib/smalltalk/tests/numbers.sx`). 14 new Number primitives (floor/ceiling/truncated/rounded/sqrt/squared/raisedTo:/factorial/even/odd/gcd:/lcm:/isInteger/isFloat). Fraction with normalisation + arithmetic + comparisons + asFloat. 620/620 total.
-- 2026-04-25: Stream hierarchy + 21 tests (`lib/smalltalk/tests/streams.sx`). ReadStream / WriteStream / ReadWriteStream as user classes; class-side `on:`; ReadStream-on-String yields characters. Bumped `test.sh` per-file timeout 60s → 180s — heavier bootstrap pushed `programs.sx` past 60s. 573/573 total.
-- 2026-04-25: HashedCollection / Set / Dictionary / IdentityDictionary + 29 tests (`lib/smalltalk/tests/hashed.sx`). Set: dedup add:, remove:, includes:, do:, addAll:. Dictionary: parallel keys/values backing; at:put:, at:ifAbsent:, includesKey:, removeKey:, keysDo:, keysAndValuesDo:. Class-side `new` chains `super new init`. Array primitive `add:` added. 552/552 total.
-- 2026-04-25: Phase 5 sequenceable-collection methods + 28 tests (`lib/smalltalk/tests/collections.sx`). 13 shared methods on `SequenceableCollection` (inject:into:, detect:, count:, …), inherited by Array/String/Symbol via `self do:`. String primitives at:/copyFrom:to:/first/last/do:. 523/523 total.
-- 2026-04-25: Exception system + 15 tests (`lib/smalltalk/tests/exceptions.sx`). Exception/Error/ZeroDivide/MessageNotUnderstood in bootstrap; signal/signal: raise via SX `raise`; on:do:/ensure:/ifCurtailed: on BlockClosure via SX `guard`. Phase 4 complete. 495/495 total.
-- 2026-04-25: `Object>>becomeForward:` + 6 tests. In-place mutation of `:class` and `:ivars` via `dict-set!`; aliases see the new identity. 480/480 total.
-- 2026-04-25: `Behavior>>compile:` + sisters + 9 tests. Parses source via `st-parse-method`, installs via runtime helpers; also added `addSelector:withMethod:` and `removeSelector:`. 474/474 total.
-- 2026-04-25: `respondsTo:` / `isKindOf:` / `isMemberOf:` + 26 tests. Universal at `st-primitive-send`. 465/465 total.
-- 2026-04-25: `Object>>perform:` family + 10 tests. Universal dispatch via `st-send` after `(str (nth args 0))` for the selector. 439/439 total.
-- 2026-04-25: Phase 4 reflection accessors (`lib/smalltalk/tests/reflection.sx`, 26 tests). Universal `Object>>class`, plus `methodDict`/`selectors`/`instanceVariableNames`/`allInstVarNames`/`classMethodDict`/`classSelectors` on class-refs. 429/429 total.
-- 2026-04-25: conformance.sh + scoreboard.{json,md} (`lib/smalltalk/conformance.sh`, `lib/smalltalk/scoreboard.json`, `lib/smalltalk/scoreboard.md`). Single-pass runner over `test.sh -v`; baseline at 5 programs / 39 corpus tests / 403 total. **Phase 3 complete.**
-- 2026-04-25: classic-corpus #5 Life (`tests/programs/life.st`, 4 tests). Spec-interpreter Conway's Life with edge handling. Block + blinker + glider initial setup verified; larger step counts pending JIT (each spec-interpreter step is ~5-8s on a 5x5 grid). Added `{e1. e2. e3}` dynamic array literal to parser + evaluator. 403/403 total.
-- 2026-04-25: classic-corpus #4 mandelbrot (`tests/programs/mandelbrot.st`, 7 tests). Escape-time iterator + grid counter. Discovered + fixed an immutable-list bug in `lit-array` eval — `map` produced an immutable list so `at:put:` raised; rebuilt via `append!`. Quicksort tests had been silently dropping ~7 cases due to that bug; now actually mutate. 399/399 total.
-- 2026-04-25: classic-corpus #3 quicksort (`tests/programs/quicksort.st`, 9 tests). Lomuto partition; verified across duplicates, already-sorted/reverse-sorted, empty, single, negatives, all-equal, plus in-place mutation. 385/385 total.
-- 2026-04-25: classic-corpus #2 eight-queens (`tests/programs/eight-queens.st`, 5 tests). Backtracking search; verified for boards of size 1, 4, 5. Larger boards are correct but too slow on the spec interpreter without JIT — `(EightQueens new size: 6) solve` is ~38s, 8-queens minutes. 382/382 total.
-- 2026-04-25: classic-corpus #1 fibonacci (`tests/programs/fibonacci.st` + `tests/programs.sx`, 13 tests). Added `smalltalk-load` chunk loader, class-side `subclass:instanceVariableNames:` (and longer Pharo variants), `Array new:` size, `methodsFor:`/`category:` no-ops, `st-split-ivars`. 377/377 total.
-- 2026-04-25: cannotReturn: implemented (`lib/smalltalk/tests/cannot_return.sx`, 5 tests). Each method-invocation gets an `{:active true}` cell shared with its blocks; `st-invoke` flips it on exit; `^expr` raises if the cell is dead. Tests use SX `guard` to catch the raise. Non-`^` blocks unaffected. 364/364 total.
-- 2026-04-25: `ifTrue:` / `ifFalse:` family pinned (`lib/smalltalk/tests/conditional.sx`, 24 tests) + parser fix: `|` is now accepted as a binary selector in expression position (tokenizer still emits it as `bar` for block param/temp delimiting; `parse-binary-message` accepts both). Caught by `false | true` truncating silently to `false`. 359/359 total.
-- 2026-04-25: `whileTrue:` / `whileFalse:` / no-arg variants pinned (`lib/smalltalk/tests/while.sx`, 14 tests). `st-block-while` returns nil per ANSI; behaviour verified under captured locals, nesting, early `^`, and zero/many iterations. 334/334 total.
-- 2026-04-25: BlockContext value family pinned (`lib/smalltalk/tests/blocks.sx`, 19 tests). Each value/valueN/valueWithArguments: variant verified plus closure semantics (read, write, later-mutation re-read), nested blocks, and block-as-arg. 320/320 total.
-- 2026-04-25: **THE SHOWCASE** — non-local return via captured method-return continuations + 14 NLR tests (`lib/smalltalk/tests/nlr.sx`). `st-invoke` wraps body in `call/cc`; blocks copy creating method's `^k`; `^expr` invokes that k. Verified across nested blocks, `to:do:` / `whileTrue:`, blocks passed to different methods (Caller→Helper escapes back to Caller), inner-vs-outer method nesting. Sentinel-based return removed. 301/301 total.
-- 2026-04-25: `super` send + 9 tests (`lib/smalltalk/tests/super.sx`). `st-super-send` walks from defining-class's superclass; class-side aware; primitives → DNU fallback. Also fixed top-level `| temps |` parsing in `st-parse` (the absence of which was silently aborting earlier eval/dnu tests — counts go from 274 → 287, with previously-skipped tests now actually running).
-- 2026-04-25: `doesNotUnderstand:` + 12 DNU tests (`lib/smalltalk/tests/dnu.sx`). Bootstrap installs `Message` (with selector/arguments accessors). Primitives signal `:unhandled` instead of erroring; `st-dnu` builds a Message and walks `doesNotUnderstand:` lookup. User Object DNU intercepts unknown sends to native receivers (Number, String, Block) too. 267/267 total.
-- 2026-04-25: method-lookup cache (`st-method-cache` keyed by `class|selector|side`, stores `:not-found` for misses). Invalidation on define/add/remove + bootstrap. `st-class-remove-method!` added. Stats helpers + 10 cache tests; 255/255 total.
-- 2026-04-25: `smalltalk-eval-ast` + 60 eval tests (`lib/smalltalk/eval.sx`, `lib/smalltalk/tests/eval.sx`). Frame chain with mutable locals/ivars (via `dict-set!`), full literal eval, send dispatch (user methods + native primitive tables for Number/String/Boolean/Nil/Array/Block/Class), block closures, while/to:do:, cascades returning last, sentinel-based `^return`. User Point class round-trip works including `+` returning a fresh point. 245/245 total.
-- 2026-04-25: class table + bootstrap (`lib/smalltalk/runtime.sx`, `lib/smalltalk/tests/runtime.sx`). Canonical hierarchy, type→class mapping for native SX values, instance construction, ivar inheritance, method install with `:defining-class` stamp, instance- and class-side method lookup walking the superclass chain. 54 new tests, 185/185 total.
-- 2026-04-25: chunk-stream parser + pragmas + 21 chunk/pragma tests (`lib/smalltalk/tests/parse_chunks.sx`). `st-read-chunks` (with `!!` doubling), `st-parse-chunks` state machine for `methodsFor:` batches incl. class-side. Pragmas with multiple keyword pairs, signed numeric / string / symbol args, in either pragma-then-temps or temps-then-pragma order. 131/131 tests pass.
-- 2026-04-25: expression-level parser + 47 parse tests (`lib/smalltalk/parser.sx`, `lib/smalltalk/tests/parse.sx`). Full message precedence (unary > binary > keyword), cascades, blocks with params/temps, literal/byte arrays, assignment chain, method headers (unary/binary/keyword). Chunk-format `! !` driver deferred to a follow-up box. 110/110 tests pass.
-- 2026-04-25: tokenizer + 63 tests (`lib/smalltalk/tokenizer.sx`, `lib/smalltalk/tests/tokenize.sx`, `lib/smalltalk/test.sh`). All token types covered except scaled decimals `1.5s2` (deferred). `#(` and `#[` emit open tokens; literal-array contents lexed as ordinary tokens for the parser to interpret.
