HS scoreboard: dict-eq fix entry + post-JIT-Phase-2 regression note

Records that the 1514/1514 claim was relative to the kernel as of
92619301; the value-handle ABI + numeric tower + JIT Phase 2 commits
introduced three regressions (1 dict-eq, now fixed in 4db1f85f, and 2
event-or-timeout wait tests still pending).

 ## Status: 1514/1514 ✓ — no remaining work in upstream conformance.
 
+### 2026-05-12 — kernel-eq regression after JIT Phase 2 + numeric tower
+
+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:
+
+  - 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.
+
+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%).
+
 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
