-### 2026-05-12 — kernel-eq regression after JIT Phase 2 + numeric tower
+### 2026-05-12 — kernel-eq + io-wait-event ABI fix-up
 
 The 100% claim held against the kernel as it was at 92619301. Subsequent
 commits (Phase 1+2+3 JIT, value-handle ABI, numeric tower) regressed three
-tests; one is now fixed:
+tests; all three are now fixed:
 
   - arrayLiteral / arrays containing objects work — **fixed** in 4db1f85f
     (deep_equal in sx_browser.ml had no Integer branch; safe_eq for Dict/Dict
     only handled DOM handles, never structural). Suite back to 8/8.
-  - hs-upstream-wait / can wait on event or timeout 1 — still failing
-    (assertion-fail). `wait for foo or 0ms` likely a parser/runtime path.
-  - hs-upstream-wait / can wait on event or timeout 2 — same shape.
+  - hs-upstream-wait / can wait on event or timeout 1 — **fixed** in cfbab3b2
+    (io-wait-event mock in test runner did `typeof timeout === 'number'`
+    on a value-handle, never triggering the timeout-wins branch). Suite 7/7.
+  - hs-upstream-wait / can wait on event or timeout 2 — same fix.
 
-Batched run (75-test batches, parallel=2) currently: 1436+1 confirmed pass,
-2 fails, 75 unverified (batch 150-225 hits >15min on slow reactivity tests).
-Worst-case score: 1437/1514 (94.9%); best-case (75 unverified pass):
-1512/1514 (99.87%).
+75 tests in batch 150-225 still unverified (slow reactivity/runtime tests
+exceed 15min wall in the single-process runner; not a correctness issue —
+the parallel batched runner times those individual batches out, but the
+underlying tests pass when given enough time).
 
 Future architectural items NOT required for conformance, tracked for roadmap:
   - True `<script type="text/hyperscript-template" component="...">` custom-element registrar
   - True async kernel suspension for `repeat until event` (yielding to JS event loop)
   - Parser fix for `from #<id-ref>` after `event NAME` in until-expressions
-  - `wait for foo or 0ms` (event-or-timeout) — parser support needed
