+# SITE-04 checkpoint: JASSUB, Danmuku Mask and Chromecast guides
+
+Six bilingual pages replace external-only or missing sidebar entries. All 16
+plugins now have dedicated guides in both languages. Original demo JavaScript is
+copied unchanged into visible Run Code blocks; Mask forwards both required plugin
+libraries. New routes record pre-change HEAD
+558e946ae538b6e0aac9754aed875ba521d6ca9d. This documents the unreleased branch,
+not the capabilities of a package currently fetched from the registry.
+
+JASSUB covers resource/rendering options, instance methods and fields, ASS data,
+callback queries, actual resize argument order and return values, ownership and
+the preserved root versus accurate runtime declarations. Mask covers all ten
+options, fixed SDK/model selection, initialization and cancellation, previous-mask
+retention, cleanup and NodeNext type-only extraction without inventing a runtime
+default alias. Chromecast covers SDK loading, live options/callbacks, media MIME
+and URL behavior, raw/normalized state, shared sessions and async runtime types.
+Session presence is not described as receiver playback. The detailed source and
+member mapping is in [the tracker](../site-content-review.md).
+
+## Verification
+
+- Node24.21.0, Yarn1.22.22 and TypeScript5.9.3. Six exact TS snippets pass strict
+  NodeNext with skipLibCheck:false and types:[], including JASSUB runtime and Mask
+  type extraction. All six runnable examples equal their original demo files.
+- Each JASSUB/Mask page validates37 distinct local file/fragment targets; each
+  Chromecast page validates38. Original/additional demo route checks pass.
+- Desktop Chromium153.0.8010.12, Firefox155.0 and Windows WebKit26.6 validate all
+  18 final guide cases without retries or page errors: HTTP load, sidebar, visible
+  Run Code, exact code/libs forwarding and language switch. Popup responses are
+  isolated; this does not execute the editor, SDK, segmentation or media playback.
+- The initial run also passed18 cases. Its Mask screenshot exposed an excessively
+  wide options table. Move the CDN link into prose and combine type/default
+  columns. A separate final run retains new screenshots and verifies no horizontal
+  table scrolling is required at the tested1100px viewport. Initial evidence is
+  preserved; no mobile responsiveness or physical-device acceptance is inferred.
+- Existing site-loading/documentation-pipeline tests:17 pass,0 failures/skips,
+  1204.8237ms. Config lint, build:llm/check:llm, build:docs and inventory checks
+  pass. Final VitePress build8.46s; Yarn10.12s. No new dependency or project script.
+- Current inventory:58 Markdown (29 per language),67 HTML,30 examples,963 core
+  members and204 assets. Enumeration is not complete semantic coverage.
+- All21 library build envelopes remain accepted. Library source, declarations,
+  distribution and dependency inputs were not changed; release blockers remain.
+
+See [the evidence record](../baselines/site04-jassub-mask-cast-guides.json).
+Generated HTML, browser assets and LLM outputs came from repository commands.
+SITE-04 remains doing; totals remain224 done/22 doing/39 todo. Two proxy and two
+tool guides, current earlier-guide checks and core semantic mapping remain.
+SITE-05/EX-03, SDK/media/device gaps and user-directed formal reviews are separate.
+
+No push, remote dispatch, deployment or publication occurred. Revert this
+checkpoint to restore previous guides, navigation and generated outputs without
+changing runtime APIs, root declarations or approved compatibility decisions.
+
+Full staged whitespace checking exits2 on12 whitespace-only template lines in
+the six new generated HTML files. Exact paths, lines and blank content were
+inspected; excluding only these files passes. Generated HTML is preserved,
+and the full check is not reported as passing. See the evidence record.
