 ## Progress log
 
+### 2026-04-26 — Bucket F: array literal arg to JS fn (+1)
+- **da2e6b1b** — `HS Bucket F: array literal arg to JS fn fix (+1 test)`. Two-part fix: (a) `generate-sx-tests.py` `js_expr_to_sx` now translates `arr.reduce(fn, init)` → `(reduce fn init arr)`, `.map(fn)` → `(map fn arr)`, `.filter(fn)` → `(filter fn arr)` so SX list arguments work with JS array HO methods. (b) `host-call-fn` in `hs-run-filtered.js` adds `sxToJs` recursive converter that unwraps SX list `._type==='list'` to native JS arrays before calling native JS functions. Together these fix functionCalls "can pass an array literal as an argument". Suite hs-upstream-expressions/functionCalls: 8/12 (unchanged SKIP ratio). Test 597: 0/1 → 1/1. Smoke 0-195: 175/195 unchanged.
+
+### 2026-04-26 — Bucket F: hs-make-object _order + assert= for dicts (+1)
+- **daea2808** — `HS Bucket F: fix hs-make-object _order + assert= for dicts (+1 test)`. Two-part fix: (a) `runtime.sx` `hs-make-object` no longer appends `_order` key to HS object literals — V8's native string-key insertion order is sufficient, and the hidden key was breaking structural equality. (b) `generate-sx-tests.py` `emit_eval` now detects when `expected_sx` contains `{` (dict syntax) and emits `assert-equal` (which uses `equal?` for deep structural equality) instead of `assert=` (which uses `=`, reference equality for dicts). Together these fix arrayLiteral "arrays containing objects work". Suite hs-upstream-expressions/arrayLiteral: 7/8 → 8/8. Smoke 0-195 unchanged at 175/195.
+
+### 2026-04-26 — Bucket F: empty multi-element fix (+1)
+- **875e9ba3** — `HS: empty multi-element fix (+1 test)`. `empty .class` compiled `(empty-target (query ".class"))` through `hs-to-sx` → `(hs-empty-target! (hs-query-first ".class"))` which only emptied the first match. Fix: detect `(query ...)` target in the `empty-target` compiler case and emit `(for-each (fn (_el) (hs-empty-target! _el)) (hs-query-all sel))`, mirroring the `add-class` pattern. Suite hs-upstream-empty: 12/13 → 13/13. Smoke 0-195: 175/195 unchanged.
+
+### 2026-04-26 — Bucket F: add CSS template interpolation (+1)
+- **5a76a040** — `HS: add CSS template interpolation fix (+1 test)`. `add {color: ${}{"red"}}` uses two consecutive brace groups: the empty `${}` marker followed by `{"red"}` for the actual value. The prior parser fix called `parse-expr` when already at the closing `}` of the empty group, returning nil. Fix: detect the empty-brace case (`brace-open` → immediately `brace-close`), skip it, then read the actual value from the next `{…}` block. Also handles normal `${expr}` correctly. Suite hs-upstream-add: 17/19 → 18/19. Smoke 0-195: 174/195 → 175/195.
+
+### 2026-04-26 — cluster 36b call result binds to it (done +1)
+- **35f498ec** — `hs: call command binds result to it via emit-set (+1 test)`. `call X then put it into Y` compiled `call X` without `emit-set`, so `it` remained nil. Wrapped call-expr in `emit-set (quote the-result) ...` so both `it` and `the-result` are updated. Suite hs-upstream-call: 5/6 → 6/6. Smoke 0-195: 173/195 → 174/195.
+
+### 2026-04-26 — cluster 7 put hyperscript reprocessing (done, final +1)
+- **247bd85c** — `hs: register promiseAString/promiseAnInt as sync test fixtures (+1 test)`. Upstream test "waits on promises" calls `promiseAString()` via window global. OCaml run_tests.ml registers these as NativeFns returning "foo"/"42" synchronously; JS runner had no equivalent. Added `globalThis.promiseAString = () => 'foo'` and `globalThis.promiseAnInt = () => 42` to hs-run-filtered.js. Suite hs-upstream-put: 37/38 → 38/38 (fully done). Smoke 0-195: 173/195 unchanged.
+
+### 2026-04-26 — cluster 7 put hyperscript reprocessing (partial +3 more)
+- **d663c91f** — `hs: stop event propagation after each hs-on handler fires (+3 tests)`. Root cause: click events bubble from b1 (inside d1) to d1, causing d1's `on click put ...` handler to re-fire and replace the just-modified b1 with fresh content (text=40). Fix: `hs-on`'s wrapped handler now calls `event.stopPropagation()` after each handler runs, preventing the bubbled click from reaching ancestor HS listeners. Tests 1147/1149/1150 now pass. Suite hs-upstream-put: 34/38 → 37/38. Smoke 0-195: 173/195 unchanged. One test remains: "waits on promises" (async/Promise issue).
