+### 2026-04-24 — cluster 20 repeat property for-loops + where (worktree re-apply)
+- **c932ad59** — `HS: repeat property for-loops + where (+3 tests)`. Worktree agent `a7c6dca2…` produced `c4241d57`; straight cherry-pick conflicted on runtime.sx with cluster 30's log-all block and cluster 27's intersection-attach helper, so logical diff was replayed surgically via sx-tree. Parser: `obj-collect` now `append`s pairs (not `cons`), preserving source order. Compiler: `emit-for` detects `coll-where` wrapping, binds the filter lambda to the for-loop variable name (not default `it`), and wraps symbol collections with `cek-try` instead of the broken `hs-safe-call` (uninitialised CEK call-ref in WASM). `array-index` emits `(hs-index …)` not `(nth …)`. Runtime: new polymorphic `hs-index` (dict/list/string/host dispatch); `hs-put-at!` default branch delegates to `hs-put!` when target is a DOM element; `hs-make-object` tracks insertion order in a hidden `_order` list; `hs-for-each` and `hs-coerce` (Keys/Entries/Map branches) prefer `_order` when present. Suite hs-upstream-repeat: 25/30 → 28/30 (remaining 2 are the `repeat forever` hangs we knowingly skip). Smoke 0-195 unchanged at 165.

 ### 2026-04-24 — cluster 27 intersection observer (worktree re-apply)
 - **0c31dd27** — `HS: intersection observer mock + on intersection (+3 tests)`. Worktree agent `ad6e17cb…` produced the logical change but its commit's reformatted compiler/runtime bodies conflicted with cluster 26's landing of resize-observer state in `tests/hs-run-filtered.js` and `runtime.sx`; straight cherry-pick hit markers on `.sx` files that can't be Edit'd. Reapplied surgically via sx-tree: (a) parser `parse-on-feat` now collects `having margin X threshold Y` clauses between `from` and body, packaging them in `:having {"margin" M "threshold" T}`; (b) compiler `scan-on` threads a new `having-info` param and, when event-name is `"intersection"`, wraps `(hs-on target "intersection" fn)` with `(do on-call (hs-on-intersection-attach! target margin threshold))`; (c) runtime adds `hs-on-intersection-attach!` which constructs an `IntersectionObserver` with `{rootMargin, threshold}` opts and a callback that dispatches an `intersection` DOM event carrying `{intersecting, entry}` detail; (d) runner adds `HsIntersectionObserver` stub that fires the callback synchronously on `observe()` with `isIntersecting=true`. Suite hs-upstream-on: 33/70 → 36/70. Smoke 0-195 unchanged at 165.
