What unlocks how many — MISSING tests by block_reason

Block reason	Missing	Example	Est. effort
unscraped-category	282	breakpoint / parses as a top-level command	low — extend scraper to cover these upstream files
unscraped-in-known-category	170	default / can default variables	low — re-scrape; file was walked but these cases missed
added-post-snapshot	122	hide / can hide via the hidden attribute strategy	low — re-scrape upstream, bump JSON snapshot
needs-pattern:${}	51	liveTemplate / script type="text/hyperscript-template" works as a l...	low — template string interpolation in HS parser
needs-script-tag	26	throw / can throw a basic exception	medium — emit <script type="text/hyperscript"> wrapper in generator
needs-websocket	12	socket / with timeout parses and uses the configured timeout	high — WebSocket mock server
needs-css-transitions	8	viewTransition / runs the body when view transitions API is unavail...	medium — transitionend event dispatch in fixtures
needs-pattern:<sel/>	8	comparisonOperator / exists works	low — parser rule for positional expr
needs-pattern:[@attr]	5	attributeRef / attributeRef with no value works	low — attribute-ref parser rule
needs-dialog-api	3	dialog / show opens a dialog (non-modal)	low — stub showModal/close on HTMLDialogElement in fixture DOM
needs-intersection-observer	1	on / on intersection fires when the element is in the viewport	medium — IntersectionObserver mock

Skip-listed tests by block_reason

Block reason	Skipped	Example	Est. effort
translation-TBD	39	fetch / can do a simple fetch w/ html	unknown — needs case-by-case generator work
needs-script-tag	5	def / functions can be namespaced	medium — emit <script type="text/hyperscript"> wrapper in generator

How this was built

1. git clone --depth 1 --branch v0.9.90 https://github.com/bigskysoftware/_hyperscript /tmp/hs-upstream; git fetch --unshallow for dated history.
2. Walked test/ (excluding vendor/, manual/, fixtures.js, global-*.js, entry.js, htmx-fixtures.js, playwright.config.js).
3. For each .js file, a small Python parser finds every test.describe(...) block, then every test(...) within it — balanced-paren scan that ignores strings, regex literals, line/block comments.
4. Category = filename stem (e.g. add.js → add). Test name = the first string literal argument of test(...).
5. Matched each upstream test against spec/tests/hyperscript-upstream-tests.json using (category, name-normalized) keys (whitespace-collapsed lowercase). Copied complexity when found; inferred it otherwise from body content (sinon./script-tag/dialog/Promise/evaluate).
6. status = runnable if present and name not in generator's SKIP_TEST_NAMES; skip-listed if present and in that set; missing otherwise.
7. block_reason classified from body content — sinon./script tag/dialog/worker/eventsource/WebSocket/MutationObserver/transition/focus/ResizeObserver patterns or <sel/>/${}/[@attr] HS syntax. Missing tests in files touched between 2026-04-09 and 2026-04-14 (git log --after --before -- test/) are tagged added-post-snapshot.
8. Regenerate: python3 tests/playwright/build-hs-manifest.py (expects /tmp/hs-upstream clone at v0.9.90).

Untranslated caveat

The markdown reports runnable = present + not skip-listed. Empirical baseline is 645 pass / 109 fail / 77 skip on 831 present tests. The ~109 failures are in-scope but reveal implementation gaps; they are not statically identifiable from upstream source without running the generator. This manifest therefore does not surface an untranslated bucket — treat the 109 empirical fails as the lower bound of that bucket inside the runnable count.
