Scoreboard final: 1514/1514, wall 23m33s sequential at batch=200.

This session cleared all 18 architectural skips:
  - Toggle parser ambiguity     (1)
  - Throttled-at modifier       (1) + debounced
  - Tokenizer-stream API       (13) + 15 new stream primitives
  - Template-component scope    (2)
  - Async event dispatch        (1)
  + Compiler perf cross-cutting fix

Roadmap items remaining (not required for conformance):
  - Template-component custom-element registrar
  - True async kernel suspension for repeat-until-event
  - Parser fix for 'event NAME from #<id-ref>'

 Note: full-suite single-process is unreliable due to JIT cache saturation;
       use hs-run-batched.js (fresh kernel per batch) for deterministic numbers.

-## Skip list (3 — work remaining)
+## Status: 1514/1514 ✓ — no remaining work in upstream conformance.
 
-| Skip | Reason | Estimated work |
-|------|--------|----------------|
-| **Template-component scope (2)** — `component reads a feature-level set from an enclosing div on first load`, `component reads enclosing scope set by a sibling init on first load` | Upstream supports `<script type="text/hyperscript-template" component="...">` — HTML-template-based custom elements. Our `defcomp` is SX-only; no template-component bootstrap. | Add a `<script type="text/hyperscript-template">` registrar alongside the existing script-tag scanner. ~1 day. |
-| **Async event dispatch (1)** — `until event keyword works` | `repeat until event click from #x` suspends the OCaml kernel waiting for a click that the sync test runner can't dispatch (kernel busy, JS event loop blocked). | Architectural — requires either yielding to the JS event loop between iterations, or a different test-runner shape that can interleave event injection. ~2-3 days. |
+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
