# PKG-MULTI-SUB-11: preserve ASS conversion on old core main
## Reproduction
Frozen npm core5.1.2 has different converter behavior across its own files.
For a plain Dialogue cue, main returns
`WEBVTT 1 00:00:01.250 --> 00:00:03.750 Plain`; the source and legacy file retain
the required header, identifier, timing and payload line breaks. The plugin's
VTT parser consequently sees no ASS cue from main. These are actual verified
tarball members, not simulated converters or version-number assumptions.
The new unit regression initially passes seven baseline/legacy assertions and
fails six main-converter samples. The initial raw-string text assertion also
compared an encoded ampersand with an equivalent literal ampersand; that fixture
failure is retained separately. Canonical HTML comparison fixes the test's text
representation comparison without weakening cue timing/count or semantic markup.
The actual browser regression with the previous plugin artifact fails because
only two of three VTT/SRT/ASS cues load on5.1.2.
## Implementation and compatibility
`src/ass-conversion.ts` is a private adapter called after request decoding. It
calls the existing host converter once. Valid output takes the normal path.
For output with the old collapsed header/timing shape, the adapter reconstructs
the old converter's supported Dialogue fields, timestamp formatting and text
cleanup, then compares the entire collapsed output. Only an exact match receives
the missing structural newlines. Custom output, comments, empty results and
nonmatching malformed conversions retain their original value; exceptions still
reject registration and release owned resources.
This small duplicate of the old supported Dialogue projection is intentional:
importing runtime code from the new core would make the plugin depend on that
core version. It is not a second general ASS parser. Keep its complete-output
comparison and frozen source/legacy parity tests when editing it. Do not extend
accepted ASS syntax or modify cue timing under this repair task.
The host's shared utility is never patched, called with a probe or replaced.
The factory, methods, event order, public types, declarations, global/ESM/CJS
entries, vendor bytes and package versions stay unchanged. No dependency or
lockfile changes are needed. The new test joins existing Yarn unit/package
commands; all three package formats and docs copies are normally rebuilt.
## Validation and limits
Exact inputs, hashes, archived reports and commands are in
[the validation index](../baselines/multiple-subtitles-ass-validation.json).
- Plugin suite315/315: the new15 tests include actual old main/legacy converters,
source parity, independent timing, Unicode, inline markup, ASS line breaks,
overlapping cues, long hours, comma text, custom/empty output and failure cleanup.
- The same targeted15-test file passes with actual main and legacy plugin input.
Its frozen-host and private-adapter checks are identified separately from
full-plugin registration/selection cases in the source.
- Source browser21/21 and actual-main browser21/21. The matrix spans
core5.1.2/5.1.7/5.3.0/5.4.0/candidate in Chromium, Firefox and Windows WebKit.
It checks UTF16 input, explicit type override, native cue times/text, multiline
and semantic HTML, overlapping translation, selection/reset and clearing.
The old-host regression now uses an actual third ASS track on both5.1 cores.
- Actual legacy browser21/21. Strict TypeScript,37 declarations with zero drift,
root and changed-script lint, CI50 and plan/risk validation pass; root lint keeps
the existing generated-doc warning. Detailed evidence is retained in the index.
Close only MULTI-SUB-ASS-01 after these checks. This is conversion into VTT, not
full ASS positioning/animation/rendering, physical-device evidence, remote CI or
package publication. The old WebKit source-seek failure reopened in task10 stays
open and is not rerun or waived by this targeted conversion matrix. Tasks05/06
and the wider refactor remain incomplete.
## Maintenance and rollback
The package architecture and test READMEs describe the adapter and replay commands.
Revert this task and rebuild the plugin to restore prior behavior; preserve the
frozen converter evidence so the known old-main failure cannot be mistaken for
successful ASS compatibility. No push or publication is included.

# 进度与证据
## PKG-MULTI-SUB-11 旧发布核心 ASS 转换适配完成
实际5.1.2 tarball证明只有main转换器丢失模板换行，同版legacy与源码正确；新增
ASS适配模块先调用宿主转换器一次，仅当完整输出匹配已复现损坏格式才补回结构换行。
有效、自定义、空输出和异常保持原行为，不修改宿主utils、不依赖新核心、无新增依赖。
冻结转换器回归修复前6失败/7通过，旧产物浏览器仅加载2/3字幕；修复后全插件315通过，
实际main/legacy各15项定向测试通过。源码/main/legacy各21项三引擎播放通过，覆盖
5.1.2/5.1.7/5.3.0/5.4.0/候选、UTF16、多行、语义HTML、独立时间与重叠翻译、选择重置。
两个旧宿主第三轨现在都使用真实ASS。严格TS、37声明零漂移、lint与CI50通过，三格式及
docs副本正常重建；关闭ASS风险。见[变更](changes/2026-09-14-PKG-MULTI-SUB-11-ass-conversion.md)
和[验证索引](baselines/multiple-subtitles-ass-validation.json)。251项：179 done、17 doing、55 todo。
不计作完整ASS排版、真机或远端CI验收。旧WebKit切源风险仍open；下一步继续task05
剩余组合验收与切源诊断，随后推进分发及其他插件未完成任务。

# Tests and fixture ownership
`test/multiple-subtitles-ass.test.js` verifies hashes of actual core5.1.2 main,
legacy and source before comparing conversion behavior. It covers the collapsed
main output, source-equivalent timings/text, valid/custom/empty passthrough and
converter failure cleanup through the real candidate plugin. It runs in both
`test:unit` and `test:multiple-subtitles`. This is native VTT conversion, not ASS
layout/rendering acceptance for JASSUB.
`test/multiple-subtitles-caption.test.js` checks the old-host view adapter with the
actual plugin bundle: native order, original update identity/scalar event payload,
escape changes, timestamp cleanup, modern-host isolation and destroy/registration

`multiple-subtitles-legacy.spec.js` uses real 5.1.2/5.1.7 cores and the candidate
plugin to check three independently timed captions, VTT/SRT, semantic HTML/CSS,
the original update method and native cue identities, scalar event payloads,
repeated updates, selection/reset and empty intervals. It uses ASS for the third
track on5.1.7; the5.1.2 published converter's malformed VTT remains a separate
task11 failure and is not covered by substituting a VTT fixture. Use
repeated updates, selection/reset and empty intervals. It now uses ASS for the third
track on both hosts: task11 repairs the exact5.1.2 main converter defect inside
the plugin. Task10's historical VTT substitution was not ASS acceptance. Use
`ARTPLAYER_MULTIPLE_SUBTITLES_ARTIFACT` for actual main/legacy package bytes.
The combination suite retains explicit published1.1/1.2 overlap-loss observations
while requiring candidate captions to contain both languages. A passing historical
observation is not a compatibility pass.
`multiple-subtitles-ass.spec.js` checks UTF16 decoding, explicit ASS type selection,
multiline text/HTML, overlapping translation, selection/reset and empty intervals
on5.1.2/5.1.7/5.3.0/5.4.0/candidate. The attachment records the unchanged original
host converter output alongside actual native cues and browser/artifact hashes.
It covers desktop video/track playback, not full ASS layout or physical devices.
