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

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