HS Conformance Scoreboard

Live tally for plans/hs-conformance-to-100.md. Update after every cluster commit.

Baseline:    1213/1496 (81.1%)  initial scrape
Snapshot:    1511/1514          upstream sync 2026-05-08 (+18 new upstream tests)
Conformance: 1511/1511 (100.0%) on counted tests; 3 documented architectural skips
Wall:        28m45s sequential (8 batches × 200) via tests/hs-run-batched.js
Target:      1514/1514 — clear the 3 remaining skips
Note: full-suite single-process is unreliable due to JIT cache saturation;
      use hs-run-batched.js (fresh kernel per batch) for deterministic numbers.

Cleared this session:
  - Toggle parser ambiguity → 2-token lookahead in parse-toggle
  - Throttled-at modifier → parser + emit-on wrap + hs-throttle!/hs-debounce!
  - Tokenizer-stream API (13) → hs-stream wrapper + 15 stream primitives

Skip list (3 — work remaining)

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.

Maintenance

After each cluster commit, update:

• Merged: pass count + delta line at top
• The row's Status / Δ / Commit in the relevant bucket
• The buckets roll-up table counts

Use mcp__hs-test__hs_test_run(start=0, end=195) + targeted-suite runs to get the real number; don't run the full suite every iteration (hangs on 196/199/200/615/1197/1198).
