-"""lua-conformance — run the PUC-Rio Lua 5.1 test suite against Lua-on-SX.
-
-Walks lib/lua/lua-tests/*.lua, evaluates each via `lua-eval-ast` on a
-long-lived sx_server.exe subprocess, classifies pass/fail/timeout per file,
-and writes lib/lua/scoreboard.{json,md}.
-
-Modelled on lib/js/test262-runner.py but much simpler: each Lua test file is
-its own unit (they're self-contained assertion scripts; they pass if they
-complete without raising). No harness stub, no frontmatter, no worker pool.
-
-Usage:
-    python3 lib/lua/conformance.py
-    python3 lib/lua/conformance.py --filter locals
-    python3 lib/lua/conformance.py --per-test-timeout 3 -v

-have to "dirt your hands".
-
-The tarball should expand in the following contents:
-  - several .lua scripts with the tests
-  - a main "all.lua" Lua script that invokes all the other scripts
-  - a subdirectory "libs" with an empty subdirectory "libs/P1",
-    to be used by the scripts
-  - a subdirectory "etc" with some extra files
-
-To run the tests, do as follows:
-
-- go to the test directory
-
-- set LUA_PATH to "?;./?.lua" (or, better yet, set LUA_PATH to "./?.lua;;"
-  and LUA_INIT to "package.path = '?;'..package.path")
-
-- run "lua all.lua"
-
-
---------------------------------------------
-Internal tests
---------------------------------------------
-
-Some tests need a special library, "testC", that gives access to
-several internal structures in Lua.
-This library is only available when Lua is compiled in debug mode.
-The scripts automatically detect its absence and skip those tests.
-
-If you want to run these tests, move etc/ltests.c and etc/ltests.h to
-the directory with the source Lua files, and recompile Lua with
-the option -DLUA_USER_H='"ltests.h"' (or its equivalent to define
-LUA_USER_H as the string "ltests.h", including the quotes). This
-option not only adds the testC library, but it adds several other
-internal tests as well. After the recompilation, run the tests
-as before.

+# 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. |
+
+### Bucket D — medium features
+
+| # | 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.
+
+| # | Subsystem | Tests | Design doc | Branch |
+|---|-----------|------:|------------|--------|
+| 36 | WebSocket + `socket` + RPC Proxy | +12-16 | `plans/designs/e36-websocket.md` | `worktree-agent-a9daf73703f520257` |
+| 37 | Tokenizer-as-API | +16-17 | `plans/designs/e37-tokenizer-api.md` | `worktree-agent-a6bb61d59cc0be8b4` |
+| 38 | SourceInfo API | +4 | `plans/designs/e38-sourceinfo.md` | `agent-e38-sourceinfo` |
+| 39 | WebWorker plugin (parser-only stub) | +1 | `plans/designs/e39-webworker.md` | `hs-design-e39-webworker` |
+| 40 | Real Fetch / non-2xx / before-fetch | +7 | `plans/designs/e40-real-fetch.md` | `worktree-agent-a94612a4283eaa5e0` |
+
+### 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.

+- **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.

 ## Progress log
 
 _Newest first. Agent appends on every commit._
 
-- 2026-04-25: lua: scoreboard iteration — `coroutine.running()` (returns current `__current-co` or nil) and `coroutine.isyieldable()`. 393/393 green.
-- 2026-04-25: lua: scoreboard iteration — `string.byte(s, i, j)` now returns multi-values for ranges (was single byte only). 393/393 green; scoreboard unchanged.
-- 2026-04-25: lua: scoreboard iteration — `math.sinh`/`cosh`/`tanh` (Lua 5.1 hyperbolic). 393/393 green; scoreboard unchanged.
-- 2026-04-25: lua: scoreboard iteration — tried two-phase eval (extract top-level `function f` decls, evaluate them BEFORE the guard so they leak to top-level env, then run the rest inside guard). Broke method-decl tests because `function a:add(...)` requires `a` to exist, and `a = {...}` was in the deferred phase-2. Reverted. Real fix needs `_G` table or AST-level rewriting of top-level returns into chunk-result mutations. 393/393 green.
-- 2026-04-25: lua: scoreboard iteration — `string.dump` stub (returns string-of-fn). Diagnosed calls.lua: file ENDS with `return deep` (line 295), which makes my `lua-has-top-return?` correctly return true, triggering the guard, which scopes user defines and breaks loadstring's lexical capture of `fat`. The fix would require either rewriting top-level returns into a different mechanism (post-processing the AST) or implementing a real `_G` global table for global assignment/lookup. Both larger.
-- 2026-04-25: lua: scoreboard iteration — `math.mod` (Lua 5.0 alias for `fmod`), `math.frexp` (mantissa/exponent split), `math.ldexp` (m·2^e). math.lua moves past line-103 `math.mod` call. Timeouts 6→3, asserts 5→7. 393/393 green.
-- 2026-04-25: lua: scoreboard iteration — `unpack(t, i, j)` now treats explicit nil for `i` or `j` as missing (defaults to 1 and `#t`). vararg.lua-style `unpack(args, 1, args.n)` works when `args.n` is nil. Asserts 4→5, timeouts 8→6 (more tests reach assertions instead of timing out). 393/393 green.
-- 2026-04-25: lua: scoreboard iteration — extended `string.format`. New `%x`/`%X`/`%o` (hex/octal), `%c` (codepoint→char via `lua-char-one`), `%q` (basic quote), width N (`%5d`), zero-pad (`%05d`), left-align (`%-5d`), `%.Ns` precision. Helpers `lua-fmt-pad` and `lua-fmt-int-base`. 393/393 green (+6 format tests).
-- 2026-04-25: lua: scoreboard iteration — `lua-eval-ast` now SKIPS the top-level guard when the parsed chunk has no top-level `return` (recursive AST walk via `lua-has-top-return?` that descends through control-flow but stops at function-body boundaries). Without the guard, top-level user defines leak to the SX top env, and `loadstring`-captured closures can find them. Verified: `function fat(x)...loadstring("return fat(...)")...end; x=fat(5)` works (was undefined). Most PUC-Rio tests still have top-level returns elsewhere, so they still need the guard. Scoreboard unchanged at 1/16 but unblocks future work.
-- 2026-04-25: lua: scoreboard iteration — math fns now error on bad/missing args (was silently returning 0). New `lua-math-num "name" x` validator wraps `abs`/`ceil`/`floor`/`sqrt`/`exp`/`sin`/`cos`/`tan`/`asin`/`acos`/`atan`/`atan2`/`pow`. errors.lua moves past assert #4 (`pcall(math.sin)` now returns false+err as expected).
-- 2026-04-24: lua: scoreboard iteration — **pattern character sets** `[...]` and `[^...]`. New `lua-pat-set-end`/`lua-pat-set-match` helpers handle ranges (`[a-z]`), classes inside sets (`[%d%a]`), negation (`[^abc]`), and `[]...]`/`[^]...]` (literal `]` as first char). Asserts 6→4, but timeouts 3→7 — many tests now reach loop-heavy code. 387/387 green (+3 charset tests).
-- 2026-04-24: lua: scoreboard iteration — `tonumber(s, base)` for bases 2-36. Validates digit ranges per base, supports leading `+`/`-`, trims whitespace. `math.lua` past assert #21. Asserts 8→6, timeouts 3→4. 384/384 green.
-- 2026-04-24: lua: scoreboard iteration — added `lua-unwrap-final-return` (post-processor that rewrites top-level `(raise (list 'lua-ret V))` → `V` so top-level defines leak to SX top and loadstring closures can see them). Tried dropping the function-guard at top level, but too many tests use `if x then return 0 else return err end` at chunk tail, whose returns aren't at the *statement-list* tail — guard still needed. Kept guard + unwrap-as-no-op. Scoreboard unchanged.
-- 2026-04-24: lua: scoreboard iteration — `lua-pat-strip-captures` helper lets patterns with `(...)` capture parens at least match (captures themselves aren't returned yet — match returns whole match). Unblocks common Lua pattern idioms like `(%a+)=(%d+)`. Scoreboard unchanged.
-- 2026-04-24: lua: scoreboard iteration — extended pattern engine to `string.match`/`gmatch`/`gsub`. `gsub` now supports string/function/table replacement modes. 381/381 green (+6 pattern tests).
-- 2026-04-24: lua: scoreboard iteration — **Lua pattern engine (minimal)** for `string.find`. Supports character classes (`%d`/`%a`/`%s`/`%w`/`%p`/`%l`/`%u`/`%c`/`%x` + complements), `.` any, `^`/`$` anchors, quantifiers `*`/`+`/`-`/`?`, literal chars, `%%`. Added `plain` arg pathway. match/gmatch/gsub still literal. Scoreboard unchanged (pattern-using tests still hit other issues downstream).
-- 2026-04-24: lua: scoreboard iteration — `package.cpath`/`config`/`loaders`/`searchers`/`searchpath` stubs. attrib.lua moves from #9 (checking `package.cpath` is a string) to "module 'C' not found" — test requires filesystem-based module loading, not tractable. Most remaining failures need Lua pattern matching (pm.lua/strings.lua), env tracking (locals.lua/events.lua), or filesystem (attrib.lua).
-- 2026-04-24: lua: scoreboard iteration — **parenthesized expressions truncate multi-return** (Lua spec: `(f())` forces single value even if `f` returns multi). Parser wraps `(expr)` in a new `lua-paren` AST node; transpile emits `(lua-first inner)`. Fixes `constructs.lua`@30 (`a,b,c = (f())` expects `a=1, b=nil, c=nil`) and `math.lua`@13. 375/375 green (+2 paren tests). Scoreboard: 8× asserts (was 10).
-- 2026-04-24: lua: scoreboard iteration — stripped `(else (raise e))` from `lua-tx-loop-guard`. SX `guard` with `(else (raise e))` hangs in a loop (re-enters the same guard). Since unmatched sentinels fall through to the enclosing guard naturally, the else is unnecessary. Diagnosed `calls.lua` undefined-`fat`: `function fat(x)` defined at Lua top-level is scoped inside the SX top-level guard's scope; loadstring-captured closures don't see it via lexical env. Fix would require either dropping the top-level guard (breaking top-level `return`) or dynamic env access — deferred.
-- 2026-04-24: lua: scoreboard iteration — **method-call double-evaluation bug**. `lua-tx-method-call` emitted `(lua-call (lua-get OBJ name) OBJ args…)` which evaluated OBJ TWICE, so `a:add(10):add(20):add(30).x` computed `110` instead of `60` (side effects applied twice). Fixed by `(let ((__obj OBJ)) (lua-call (lua-get __obj name) __obj args…))`. 373/373 green (+1 chaining test).
-- 2026-04-24: lua: **🎉 FIRST PASSING PUC-Rio TEST — 1/16 runnable (6.2%)**. `verybig.lua` now passes: needed `io.output`/`io.input`/`io.stdout`/`io.stderr` stubs, made `os.remove` return `true` (test asserts on it), and added `dofile`/`loadfile` stubs. All cumulative fixes (returns/break/scoping/escapes/precedence/vararg/tonumber-trim) combined make this test's full happy path work end-to-end. 372 unit tests. Failure mix: 10× assertion / 4× timeout / 1× call-non-fn.
-- 2026-04-24: lua: scoreboard iteration — **proper `break` via guard+raise sentinel** (`lua-brk`) + auto-first multi-values in arith/concat. Loop break dispatch was previously a no-op (emitted bare `'lua-break-marker` symbol that nothing caught); converted to raise+catch pattern, wrapping the OUTER invocation of `_while_loop`/`_for_loop`/`_repeat_loop`/`__for_loop` in a break-guard (wrapping body doesn't work — break would just be caught and loop keeps recursing). Also `lua-arith`/`lua-concat`/`lua-concat-coerce` now `lua-first` their operands so multi-returns auto-truncate at scalar boundaries. 372/372 green (+4 break tests). Scoreboard: 10×assert / 4×timeout / 2×call-non-fn (no more undef-symbol or compare-incompat).
-- 2026-04-24: lua: scoreboard iteration — **proper early-return via guard+raise sentinel**. Fixes long-logged limitation: `if cond then return X end ...rest` now exits the enclosing function; `rest` is skipped. `lua-tx-return` raises `(list 'lua-ret value)`; every function body and the top-level chunk + loadstring'd chunks wrap in a guard that catches the sentinel and returns its value. Eliminates "compare incompatible types" from constructs.lua (past line 40). 368/368 green (+3 early-return tests).
-- 2026-04-24: lua: scoreboard iteration — **unary-minus / `^` precedence fix**. Per Lua spec, `^` binds tighter than unary `-`, so `-2^2` should parse as `-(2^2) = -4`, not `(-2)^2 = 4`. My parser recursed into `parse-unary` and then let `^` bind to the already-negated operand. Added `parse-pow-chain` helper and changed the `else` branch of `parse-unary` to parse a primary + `^`-chain before returning; unary operators now wrap the full `^`-chain. Fixed `constructs.lua` past assert #3 (moved to compare-incompatible). 365/365 green (+3 precedence tests).
-- 2026-04-24: lua: scoreboard iteration — `lua-byte-to-char` regression fix. My previous change returned 2-char strings (`"\a"` etc.) for bytes that SX string literals can't express (0, 7, 8, 11, 12, 14–31, 127+), breaking `'a\0a'` length from 3 → 4. Now only 9/10/13 and printable 32-126 produce real bytes; others use a single `"?"` placeholder so `string.len` stays correct. literals.lua back to failing at assert #4 (was regressed to #2).
-- 2026-04-24: lua: scoreboard iteration — **decimal string escapes** `\ddd` (1-3 digits). Tokenizer `read-string` previously fell through to literal for digits, so `"\65"` came out as `"65"` not `"A"`. Added `read-decimal-escape!` consuming up to 3 digits while keeping value ≤255, plus `\a`/`\b`/`\f`/`\v` control escapes and `lua-byte-to-char` ASCII lookup. 362 tests (+2 escape tests).
-- 2026-04-24: lua: scoreboard iteration — **`loadstring` error propagation**. When `loadstring(s)()` was implemented as `eval-expr ( (let () compiled))`, SX's `eval-expr` wrapped any propagated `raise` as "Unhandled exception: X" — so `error('hi')` inside a loadstring'd chunk came out as that wrapped string instead of the clean `"hi"` Lua expects. Fix: transpile source once into a lambda AST, `eval-expr` it ONCE to get a callable fn value, return that — subsequent calls propagate raises cleanly. Guarded parse-failure path returns `(nil, err)` per Lua convention. vararg.lua now runs past assert #18; errors.lua past parse stage.
-- 2026-04-24: lua: scoreboard iteration — `table.sort` O(n²) insertion-sort → **quicksort** (Lomuto partition). 1000-element sorts finish in ms; but `sort.lua` uses 30k elements and still times out even at 90s (metamethod-heavy interpreter overhead). Correctness verified on 1000/5000 element random arrays.
-- 2026-04-24: lua: scoreboard iteration — `dostring(s)` alias for `loadstring(s)()` (Lua 5.0 compat used by literals.lua). Diagnosed `locals.lua` call-non-fn at call #18 → `getfenv/setfenv` stub-return pattern fails `assert(getfenv(foo("")) == a)` (need real env tracking, deferred). Tokenizer long-string-leading-NL rule verified correct.
-- 2026-04-24: lua: scoreboard iteration — Lua 5.0-style `arg` auto-binding inside vararg functions (some PUC-Rio tests still rely on it). `lua-varargs-arg-table` builds `{1=v1, 2=v2, …, n=count}`; transpile adds `arg` binding alongside `__varargs` when `is-vararg`. Diagnosis done with assert-counter instrumentation — literals.lua fails at #4 (long-string NL rule), vararg.lua was at #2 (arg table — FIXED), attrib.lua at #9, locals.lua now past asserts into call-non-fn. 360 tests.
-- 2026-04-24: lua: scoreboard iteration — **`loadstring` scoping**. Temporarily instrumented `lua-assert` with a counter, found `locals.lua` fails at assertion #5: `loadstring('local a = {}')() → assert(type(a) ~= 'table')`. The loadstring'd code's `local a` was leaking to outer scope because `lua-eval-ast` ran at top-level. Fixed by transpiling once and wrapping the AST in `(let () …)` before `eval-expr`.
-- 2026-04-24: lua: scoreboard iteration — **`if`/`else`/`elseif` body scoping** (latent bug). `else local x = 99` was leaking to enclosing scope. Wrap all three branches in `(let () …)` via `lua-tx-if-body`. 358 tests.
-- 2026-04-24: lua: scoreboard iteration — **`do`-block proper scoping**. Was transpiling `do ... end` to a raw `lua-tx` pass-through, so `define`s inside leaked to the enclosing scope (`do local i = 100 end` overwrote outer `i`). Now wraps in `(let () body)` for proper lexical isolation. 355 tests, +2 scoping tests.
-- 2026-04-24: lua: scoreboard iteration — `lua-to-number` trims whitespace before `parse-number` (Lua coerces `" 3e0 "` in arithmetic). math.lua moved past the arith-type error to deeper assertion-land. 12× asserts / 3× timeouts / 1× call-non-fn.
-- 2026-04-24: lua: scoreboard iteration — `table.getn`/`setn`/`foreach`/`foreachi` (Lua 5.0-era), `string.reverse`. `sort.lua` unblocked past `getn`-undef; now times out on the 30k-element sort body (insertion sort too slow). 13 fail / 3 timeout / 0 pass.
-- 2026-04-24: lua: scoreboard iteration — parser consumes trailing `;` after `return`; added `collectgarbage`/`setfenv`/`getfenv`/`T` stubs. All parse errors and undefined-symbol failures eliminated — every runnable test now executes deep into the script. Failure mix: **11× assertion failed**, 2× timeout, 2× call-non-fn, 1× arith. Still 0/16 pass but the remaining work is substantive (stdlib fidelity vs the exact PUC-Rio assertions).
-- 2026-04-24: lua: scoreboard iteration — trailing-dot number literals (`5.`), preload stdlibs in `package.loaded` (`string`/`math`/`table`/`io`/`os`/`coroutine`/`package`/`_G`), `arg` stub, `debug` module stub. Assertion-failure count 4→**8**, parse errors 3→**1**, call-non-fn stable, module-not-found gone.
-- 2026-04-24: lua: scoreboard iteration — **vararg `...` transpile**. Parser already emitted `(lua-vararg)`; transpile now: (a) binds `__varargs` in function body when `is-vararg`, (b) emits `__varargs` for `...` uses; `lua-varargs`/`lua-spread-last-multi` runtime helpers spread multi in last call-arg and last table-pos positions. Eliminated all 6× "transpile: unsupported" failures; top-5 now all real asserts. 353 unit tests.
-- 2026-04-24: lua: scoreboard iteration — added `rawget`/`rawset`/`rawequal`/`rawlen`, `loadstring`/`load`, `select`, `assert`, `_G`, `_VERSION`. Failure mix now 6×vararg-transpile / 4×real-assertion / 3×parse / 2×call-non-fn / 1×timeout (was 14 parse + 1 print undef at baseline); tests now reach deep into real assertions. Still 0/16 runnable — next targets: vararg transpile, goto, loadstring-compile depth. 347 unit tests.
-- 2026-04-24: lua: `require`/`package` via preload-only (no filesystem search). `package.loaded` caching, nil-returning modules cache as `true`, unknown modules error. 347 tests.
-- 2026-04-24: lua: `os` stub — time/clock monotonic counter, difftime, date (default string / `*t` dict), getenv/remove/rename/tmpname/execute/exit stubs. Phase 6 complete. 342 tests.
-- 2026-04-24: lua: `io` stub + `print`/`tostring`/`tonumber` globals. io buffers to internal `__io-buffer` (tests drain it via `io.__buffer()`). print: tab-sep + NL. tostring respects `__tostring` metamethod. 334 tests.
-- 2026-04-24: lua: `table` lib — insert (append / at pos, shifts up), remove (last / at pos, shifts down), concat (sep, i, j), sort (insertion sort, optional cmp), unpack + table.unpack, maxn. Caught trap: local helper named `shift` collides with SX's `shift` special form → renamed to `tbl-shift-up`/`tbl-shift-down`. 322 tests.
-- 2026-04-24: lua: `math` lib — pi/huge + abs/ceil/floor/sqrt/exp/log/log10/pow/trig (sin/cos/tan/asin/acos/atan/atan2)/deg/rad/min/max (&rest)/fmod/modf/random (0/1/2 arg)/randomseed. Most ops delegate to SX primitives; log w/ base via change-of-base. 309 tests.
-- 2026-04-24: lua: `string` lib — len/upper/lower/rep/sub (1-idx + neg)/byte/char/find/match/gmatch/gsub/format. Patterns are literal-only (no `%d`/etc.); format is `%s`/`%d`/`%f`/`%%` only. `string.char` uses printable-ASCII lookup + tab/nl/cr. 292 tests.
-- 2026-04-24: lua: phase 5 — coroutines (create/resume/yield/status/wrap) via `call/cc` (perform/cek-resume not exposed to SX userland). Handles multi-yield + final return + arg passthrough. Fix: body's final return must jump via `caller-k` to the **current** resume's caller, not unwind through the stale first-call continuation. 273 tests.
-- 2026-04-24: lua: generic `for … in …` — parser split (`=` → num, else `in`), new `lua-for-in` node, transpile to `let`-bound `f,s,var` + recursive `__for_loop`. Added `ipairs`/`pairs`/`next`/`lua-arg` globals. Lua fns now arity-tolerant (`&rest __args` + indexed bind) — needed because generic for always calls iter with 2 args. Noted early-return-in-nested-block as pre-existing limitation. 265 tests.
-- 2026-04-24: lua: `pcall`/`xpcall`/`error` via SX `guard` + `raise`. Added `lua-apply` (arity-dispatch 0-8, apply fallback) because SX `apply` re-wraps raises as "Unhandled exception". Table payloads preserved (`error({code = 42})`). 256 total tests.
-- 2026-04-24: lua: phase 4 — metatable dispatch (`__index`/`__newindex`/arith/compare/`__call`/`__len`), `setmetatable`/`getmetatable`/`type` globals, OO `self:method` pattern. Transpile routes all calls through `lua-call` (stashed `sx-apply-ref` to dodge user-shadowing of SX `apply`). Skipped `__tostring` (needs `tostring()` builtin). 247 total tests.
-- 2026-04-24: lua: PUC-Rio scoreboard baseline — 0/16 runnable pass (0.0%). Top modes: 14× parse error, 1× `print` undef, 1× vararg transpile. Phase 3 complete.
-- 2026-04-24: lua: conformance runner — `conformance.sh` shim + `conformance.py` (long-lived sx_server, epoch protocol, classify_error, writes scoreboard.{json,md}). 24 files classified in full run: 8 skip / 16 fail / 0 timeout.
-- 2026-04-24: lua: vendored PUC-Rio 5.1 test suite (lua5.1-tests.tar.gz from lua.org) to `lib/lua/lua-tests/` — 22 .lua files, 6304 lines; README kept for context.
-- 2026-04-24: lua: raw table access — fix `lua-set!` to use `dict-set!` (mutating), fix `lua-len` `has?`→`has-key?`, `#t` works, mutation/chained/computed-key writes + reference semantics. 224 total tests.
-- 2026-04-24: lua: phase 3 — table constructors verified (array, hash, computed keys, mixed, nested, dynamic values, fn values, sep variants). 205 total tests.
-- 2026-04-24: lua: multi-return — `lua-multi` tagged value, `lua-first`/`lua-nth-ret`/`lua-pack-return` runtime, tail-position spread in return/local/assign. 185 total tests.
-- 2026-04-24: lua: phase 3 — functions (anon/local/top-level) + closures verified (lexical capture, mutation-through-closure, recursion, HOFs). 175 total tests.
 - 2026-04-24: lua: phase 2 transpile — arithmetic, comparison, short-circuit logical, `..` concat, if/while/repeat/for-num/local/assign. 157 total tests green.
 - 2026-04-24: lua: parser (exprs with precedence, all phase-1 statements, funcbody, table ctors, method/chained calls) — 112 total tokenizer+parser tests
 - 2026-04-24: lua: tokenizer (numbers/strings/long-brackets/keywords/ops/comments) + 56 tests

-## Known limitations (own code, not shared)
-
-- **`require` supports `package.preload` only** — no filesystem search (we don't have Lua-file resolution inside sx_server). Users register a loader in `package.preload.name` and `require("name")` calls it with name as arg. Results cached in `package.loaded`; nil return caches as `true` per Lua convention.
-- **`os` library is a stub** — `os.time()` returns a monotonic counter (not Unix epoch), `os.clock()` = counter/1000, `os.date()` returns hardcoded "1970-01-01 00:00:00" or a `*t` table with fixed fields; `os.getenv` returns nil; `os.remove`/`rename` return nil+error. No real clock/filesystem access.
-- **`io` library is a stub** — `io.write`/`print` append to an internal `__io-buffer` (accessible via `io.__buffer()` which returns + clears it) instead of real stdout. `io.read`/`open`/`lines` return nil. Suitable for tests that inspect output; no actual stdio.
-- **`string.find`/`match`/`gmatch`/`gsub` patterns are LITERAL only** — no `%d`/`%a`/`.`/`*`/`+`/etc. Implementing Lua patterns is a separate work item; literal search covers the common case.
-- **`string.format`** supports only `%s`, `%d`, `%f`, `%%`. No width/precision flags (`%.2f`, `%5d`).
-- **`string.char`** supports printable ASCII 32–126 plus `\t`/`\n`/`\r`; other codes error.
-- ~~Early `return` inside nested block~~ — **FIXED 2026-04-24** via guard+raise sentinel (`lua-ret`). All function bodies and the top-level chunk wrap in a guard that catches the return-sentinel; `return` statements raise it.
