+The vendor default entity table still has its historical semicolon bug, preserved

+exact amp/lt/gt/lrm/rlm/nbsp references through the existing constructor option.
+Historical partial/bare-name handling remains via the old aliases; numeric and

+Literal text is escaped separately from semantic cue tags before the serializer's
+outer escaping. The renderer's existing onVttLoad unescape removes only that outer
+layer, leaving escaped literal tags/timestamps for native VTT and HTML display.
+Wrappers are sibling text nodes around the prepared node; they are never assigned

+# PKG-MULTI-SUB-08: entity text and semantic tag wrapping
+
+Baseline: 4acf85ea696a99f05fce71089711bc4a4ca0d5b6. This independent correction
+precedes task05's complete core/combination acceptance; it does not complete that
+task or publication readiness.
+
+## Old behavior and corrections
+
+Nine historical implementations reproduce `&lt;`/`&gt;`/`&amp;` decoding with stray
+semicolons. The vendor's default table contains bare keys, while its exact-match
+branch looks for the semicolon-terminated key and falls through to partial-match
+handling. `text.ts` supplies both forms for the six existing named entities using
+the parser's already-supported constructor option. Bare/partial-name aliases,
+numeric references and unknown-reference handling retain the existing parser path.
+No upstream/vendor execution body or provenance snapshot is edited.
+
+Correctly decoded text must remain literal after the existing onVttLoad unescape.
+Text values therefore receive a separate escaping layer before the serializer
+protects the complete VTT. Literal `<b>` and timestamp-shaped text remain visible
+text; `&amp;lt;` displays `&lt;` rather than decoding repeatedly. Real b/i/c/v/ruby
+cue nodes remain semantic nodes, and inline timestamps retain their numeric data.
+
+Related tag coverage exposed a second historical bug: the old merge assigned an
+HTML wrapper to a semantic node's annotation field, yielding output such as
+`<b <div ...>undefined</div>>bold</b>`. Nine historical implementations now reproduce
+that exact malformed structure separately. Merge wraps prepared nodes with sibling
+opening/closing text nodes instead. CSS hooks remain `.art-subtitle-<name>`; markup
+annotations are preserved and source trees are still immutable across selections.
+Plain-text/timing output remains byte-matched outside these intentional fixes.
+
+## Structure, compatibility and ownership
+
+- `text.ts`: entity configuration and literal-text protection through the two
+  existing serialization/HTML stages. It introduces no browser API or dependency.
+- `merge.ts`: recursively prepare text/timestamp/object nodes and wrap top-level
+  nodes without changing annotations. A simple loop avoids requiring Array.flatMap
+  in older environments. Parsing/selection order and original cue times remain.
+- Vendor parser/serializer, request/lifetime/render/caption code, public types,
+  factory/default alias, tracks/reset, Promise behavior and distribution paths
+  are unchanged. This is an authored adapter around a frozen vendor, not a vendor
+  upgrade or an unexplained relaxation of its fingerprint check.
+
+There are no new resources or lifetime responsibilities. Existing download, URL,
+destroy/restart and host-error checks still apply. Corrected entity/tag output is
+an intentional bug fix; malformed attributes and visible semicolons are not kept
+as compatibility requirements. Tests formerly comparing those erroneous serialized
+bytes move to explicit corrected text/markup expectations. Raw ampersands and
+malformed angle text retain a separate actual-old-versus-current visible-output
+comparison. No historical failure fixture is rewritten to pretend old releases
+were correct.
+
+## Verification
+
+Source/log/artifact hashes and actual counts are in
+[multiple-subtitles-entities-validation.json](../baselines/multiple-subtitles-entities-validation.json).
+
+- The initial5 entity/rendering tests fail against the frozen pre-change bundle.
+  The final expanded11-case file is rerun against both old and new artifacts.
+- Full package suite294 passes, including11 focused cases, immutable tree and
+  timestamps,9 historical entity failures,9 historical malformed-tag failures,
+  actual release contracts/types and complete unchanged vendor parity/notices.
+- Windows source browser suite42 passes: entity/markup native VTT and HTML display
+  on published/candidate cores, plus existing playback, SRT, timestamps, selection,
+  source replacement and cleanup. An early implementation used flatMap; the final
+  equivalent loop has full Node coverage and actual built-browser verification.
+- Production main/legacy artifacts each run the focused Node suite; actual main
+  also runs entity display in all3 engines on both core variants. UMD/legacy/ESM
+  and matching docs copies are regenerated using the normal build.
+- Strict package TypeScript passes. Initial Unicode escape casing/list formatting
+  lint errors are corrected; final root lint has only its one existing docs type
+  warning. CI and final plan/risk checks are recorded separately.
+
+This is desktop engine evidence, not physical Safari/mobile, all historical core
+versions or a remote CI run. Complete core combinations remain task05, distribution
+and demo acceptance task06. No lockfile, dependency, public declaration or version
+change. The package architecture and test maintenance documentation explain the
+adapter and corrected behavior. Revert the dedicated task08 commit, including
+generated outputs, to restore the prior implementation. Local commit only; no
+push or npm publication.

 # 进度与证据

+## PKG-MULTI-SUB-08 字幕实体与标签包装完成
+
+通过解析器既有实体表入口修复标准命名实体后多余分号，保留原始vendor文件与
+来源校验；独立转义字面文本，避免实体形式的标签/时间戳被再次解释。同步修复
+把包装节点塞进b等标签注释字段的问题，改为节点外包装，保留CSS钩子与时间戳。
+九套历史实现分别复现两类旧缺陷，最终11项新用例在旧bundle中8红3绿，候选及
+实际main/legacy各11项全绿。完整插件294项、源码浏览器42项、实际main浏览器
+6项、CI50项通过；严格TS与vendor校验通过，lint 1既有warning。三格式与docs
+副本正常重建，公开类型/依赖/版本未改。详见[记录](changes/2026-09-14-PKG-MULTI-SUB-08-entities.md)
+和[证据](baselines/multiple-subtitles-entities-validation.json)。关闭实体与标签包装
+风险，247项变为175 done、16 doing、56 todo；这不完成全部旧核心/真机/分发
+验收，下一步继续任务05组合验证。独立本地提交，无推送/发布。

 # Tests and fixture ownership

+`test/multiple-subtitles-entities.test.js` checks named entities, literal tags,
+double encoding, nested semantic tags and selection/reset through the real plugin.
+The vendor parity suite stays unchanged: the plugin uses the parser's existing
+entity-table option. Historical malformed-tag and stray-semicolon tests continue
+to assert old defects; corrected cases have explicit rendering expectations instead
+of treating those old serialized bytes as a required contract. Browser entity
+tests compare native VTT fragments and actual HTML captions on both core variants.
+
 `yarn test:library` runs actual library builds, build-input freshness checks and the
 scaffold's generated consumers. The new build modules live in `scripts/library/`;
 `yarn typecheck:library` checks them and the retained JS/MJS entrypoints. Browser
