- External players: MPV, VLC (via IPC to Electron backend)

- Embedded MPV (experimental, macOS/Windows/Linux): renders mpv video inside the Electron window through a native addon. macOS uses the libmpv render API in an `NSOpenGLView`; Windows uses in-process libmpv with `--wid` against an app-owned child `HWND`; Linux spawns an out-of-process `mpv --wid=<x11-window>` controlled over a JSON IPC socket (X11/XWayland only, requires system `mpv` on PATH; subtitles/speed/aspect/recording are not exported there). mpv's own screensaver inhibition does not apply to any of these paths, so `EmbeddedMpvNativeService` holds an Electron `powerSaveBlocker` (`prevent-display-sleep`) whenever any session's status is `playing`, and releases it on pause, dispose, or shutdown. Renderer bounds are CSS pixels; the service converts them to native units in the main process (`embedded-mpv-bounds.util.ts`: × page zoom everywhere, × display scale on Windows/Linux whose child windows are positioned in physical pixels; frame-copy bounds stay unscaled), and the session controller re-syncs bounds when `devicePixelRatio` changes.

- Finds the same movie in the user's other imported playlists and adds a "Sources N" chip to the Xtream VOD action row (only when ≥1 alternative exists), plus a `.source-caption` line reporting where playback is coming from. The chip opens a 460px anchored CDK-overlay popover (`libs/ui/components/src/lib/vod-sources/`; not `MatMenu`, which caps its width at 280px), reused unchanged in the inline player's now-playing bar and on the playback-error screen. Both chips are handed the same `matchKind` and `vodAutoFailover` and both write the setting back. The chip counts alternative **streams**; the caption ("also found in N other playlists") counts distinct **playlists** via `alternativePlaylistCount`, because the popover groups one portal's copies under that portal.
|
||||
- Scope v1 is **Xtream ↔ Xtream, movies only, Electron only**. Stalker never reaches the `content` table and M3U is a JSON blob whose search forces `content_type:'live'`; both are additive later since `VodSourceCandidate.portalType` already carries all three. In the PWA every entry point is gated off by a bridge `typeof` check and the chip renders nothing.
|
||||
- **Metadata provenance is the core contract.** Every field is `{value, provenance}` where `api`/`probe` are facts (plain tag), `parsed` is a title-regex guess (tag prefixed `~`, warn colour), and absent renders **no tag at all** plus a `check` chip. `factualOnly()` in `vod-source-metadata.util.ts` is the only accessor allowed for ranking/failover, so guesses are structurally unable to influence a decision. `VodSourceProbeStatus` separates `fail` (contacted and refused) from `unknown` (timed out / blocked / no capability) — an unchecked source is never shown as offline. Quality is derived from pixel **width** because letterboxing crops height — but a known height vetoes the answer on every tier, since cropping only removes lines: a taller frame is a different shape (1440×1080 anamorphic or 1600×900 are not 720p, 960×540 is not 576p) and gets no tag rather than a wrong one carrying `api` provenance. The route's OWN row is never resolved, so it takes its facts from the `get_vod_info` the page already loaded (`providerVodMetadataOf`, shared with the resolver) and picks them up via `refreshRouteFacts()` even when they arrive without changing the movie identity — otherwise `audioDiffersFactually` has nothing on one side and the dub warning cannot fire on a route-to-alternative switch.
|
||||
- Discovery (`DB_FIND_TITLE_SOURCES`, trigram FTS over `content_title_fts`) is lazy and returns only what the `content` table can prove; titles whose tokens are all shorter than three characters ("Up", "It") fall back to a scan, since the trigram tokenizer cannot index them at all. A source that is never read looks exactly like one that does not exist, so: the current playlist is excluded **in SQL** and duplicates collapse there too (`GROUP BY cat.playlist_id, c.xtream_id` before the limit — one playlist's dozens of identically ranked category rows would otherwise crowd out every alternative), and the scan matches an ASCII token as a whole word (`' ' || LOWER(title) || ' ' GLOB '*[^a-z0-9]it[^a-z0-9]*'`) ordered by title length **with no row limit** — FTS keeps its 60-row window because it ranks by relevance, while a scan cannot rank, and the GLOB reads every row regardless so a limit would only truncate the answer. The year gate covers BOTH match tiers: `normalizeTitleKeys` strips bracketed segments, so "Dune (1984)" normalizes identically to "Dune" and would otherwise be an *exact* match for the 2021 film; a bracketed year is read out of the raw title and a stated disagreement rejects the row — but the two tiers read different forms: the base tier accepts bracketed or trailing (it just stripped a trailing year, the only thing separating "Dune 1984" from "Dune 2021"), while the exact tier reads bracketed ONLY, since reaching it means both titles are the same string and a trailing number is then part of the NAME ("Blade Runner 2049" against a metadata year of 2017 would otherwise vanish once enrichment lands). A non-ASCII token cannot be folded by `LOWER()` (ASCII-only) but CAN be by a GLOB character class (UTF-8 code points), so `caseInsensitiveGlobPattern` folds the case in JS and emits one `[lowerUpper]` class per character — returning `null`, leaving the two substring tests alone, for a GLOB metacharacter or a length-changing case map (`ß`→`SS`). The movie's own year comes from `releaseTagYear` (bracketed or trailing only), never `extractYear`: a year inside the NAME ("2001: A Space Odyssey") would fail every genuine 1968 copy at the year gate and move the pin key once enrichment lands. One row inside the excluded playlist is kept when the caller names it (`keepContentId`), because a pin can point at another copy in the playlist being viewed — the host reads the pin before discovery for exactly this. Resolution is deferred to click/pin/check because `content` stores no `container_extension` and `constructVodUrl` returns `''` without one — each alternative costs a live `get_vod_info` against the foreign playlist's credentials.

- Pins are keyed portal-agnostically (`tmdb:{id}` else `title:{base}:{year}` else the yearless `title:{base}:`, `vod_source_pins` table); enrichment supplies the id and the year late, so a pin may sit under any poorer form — three key sets (`pinKeysFor`): `lookup` passes every alias most-trusted-first, `write` holds only keys naming exactly one film, and `loaded` records where the pin on screen was found — the yearless alias is readable but never written or deleted on spec, since it is shared by every remake, with the single exception of the row this session actually read. A write stores the decision under **every** key in `write` (`setVodSourcePin(db, pin, retireKeys, aliasKeys)`: one upsert per key plus the leftover retirement, in a single transaction), because a movie's identity grows — recorded only under the enriched `tmdb:` key, a pin is invisible to the next reopen, which starts out with just a title and a year, and stays invisible for good if enrichment is off or never answers. A pin is not decoration: the primary Play action starts from the pinned source (except when that button reads Stop — an active external session wins, or the control would launch a second player), and it outranks everything else in failover ranking. The row changes only after the write lands, so a refused pin is never shown as saved. Starting a pinned source loads THAT source's own playback position — progress is keyed by (playlist, stream), so the row the page loaded belongs to the route's copy. The primary button says nothing at all until that row is in, and "is it in" is answered by comparing the loaded pin **id** rather than mere presence, or re-pinning would leave the button wearing the previous copy's timecode. An external player launched for an alternative carries the OTHER playlist's ids, so `VodDetailsPlaybackBindings.activeSource` feeds one `ownsContent()` predicate used by BOTH the session matcher and the playback-position bridge — if they disagree, the page shows Stop for a session whose progress it throws away and a later switch rewinds hours. Two identity keys: `vodMultiSourceMovieKey` (title, year, tmdbId) makes TMDB enrichment re-trigger discovery and rebuild the pin keys, while `vodMultiSourceSessionKey` (`playlistId:contentId`) decides whether that rerun is a refresh or a new session — a refresh keeps the active source, its resolved facts, the tried set, the live position and any switch in flight; only a different film resets them.
|
||||
- Claims in the present tense (the "Playing from" caption and the source row's `Playing` badge) are gated on `VodDetailsRouteComponent.playbackLive`, never on `isActive` — discovery marks a source active before anything plays and it stays active after the player closes. Inline that means a `timeupdate` has arrived (`inlinePlayback()` is only the request to play); external it means the session is past `launching`. A merely selected row reads `Current`.
|
||||
- Pins are included in playlist backup as the optional `sourcePins` collection, carried under the playlist they point at; `matchKey` survives untouched and only the playlist id is remapped on restore (older archives simply lack the field).

# Structured Shaka Diagnostics Implementation Plan
|
||||
|
||||
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
|
||||
|
||||
**Goal:** Replace raw Shaka error retention with a version-locked, public,
|
||||
allowlisted evidence boundary that distinguishes recoverable events from
|
||||
terminal load failures.
|
||||
|
||||
**Architecture:** Normalize only Shaka 5.2.2 public severity/category/code
|
||||
values and documented HTTP status layouts into `ShakaPlaybackEvidence`.
|
||||
`ShakaVideoSession` supplies the lifecycle disposition, the classifier maps
|
||||
only exact category/code pairs, and the existing UI renders only structured
|
||||
evidence.
|
||||
|
||||
**Tech Stack:** Angular 21, TypeScript 5.9, Shaka Player 5.2.2, Jest through
|
||||
Nx, Markdown architecture and release-note documentation.
|
||||
|
||||
---
|
||||
|
||||
### Task 0: Establish The Evidence And Baseline
|
||||
|
||||
**Files:**
|
||||
|
||||
- Verify: `package.json`
|
||||
- Verify: `pnpm-lock.yaml`
|
||||
- Verify: `node_modules/shaka-player/lib/util/error.js`
|
||||
- Verify: `node_modules/shaka-player/lib/net/http_plugin_utils.js`
|
||||
- Verify: `node_modules/shaka-player/lib/net/networking_engine.js`
|
||||
- Verify: `node_modules/shaka-player/lib/media/preload_manager.js`
|
||||
- Verify: `node_modules/shaka-player/lib/player.js`
|
||||
- Verify: `node_modules/shaka-player/dist/shaka-player.compiled.d.ts`
|
||||
|
||||
- [x] **Step 1: Install locked dependencies**
|
||||
|
||||
Run:
|
||||
|
||||
```bash
|
||||
pnpm install --frozen-lockfile
|
||||
```
|
||||
|
||||
Expected: exit 0, Shaka Player `5.2.2`, and no lockfile change.
|
||||
|
||||
- [x] **Step 2: Verify Nx workspace discovery**
|
||||
|
||||
Run:
|
||||
|
||||
```bash
|
||||
pnpm nx show projects
|
||||
```
|
||||
|
||||
Expected: exit 0 and output containing `ui-playback`, `web`, and `web-e2e`.
|
||||
|
||||
- [x] **Step 3: Run the affected-project baseline**
|
||||
|
||||
Run:
|
||||
|
||||
```bash
|
||||
pnpm nx test ui-playback
|
||||
```
|
||||
|
||||
Expected: 86 suites and 801 tests pass before implementation.
|
||||
|
||||
- [x] **Step 4: Audit the installed public runtime**
|
||||
|
||||
Confirm:
|
||||
|
||||
```text
|
||||
shaka.Player.version = v5.2.2
|
||||
Severity = { RECOVERABLE: 1, CRITICAL: 2 }
|
||||
Category = {
|
||||
NETWORK: 1, TEXT: 2, MEDIA: 3, MANIFEST: 4, STREAMING: 5,
|
||||
DRM: 6, PLAYER: 7, CAST: 8, STORAGE: 9, ADS: 10
|
||||
}
|
||||
BAD_HTTP_STATUS data[1] = HTTP status
|
||||
LICENSE_REQUEST_FAILED data[0] = nested Shaka network error
|
||||
SERVER_CERTIFICATE_REQUEST_FAILED data[0] = nested Shaka network error
|
||||
```
|
||||
|
||||
Confirm the installed event order:
|
||||
|
||||
```text
|
||||
recoverable Player#error -> engine continues
|
||||
critical PreloadManager error -> public error event -> load rejection
|
||||
direct manifest/parser throw -> load rejection without required error event
|
||||
attempts exhausted -> final recoverable-severity error rejects load
|
||||
```
|
||||
|
||||
### Task 1: Drive The Public Shaka Evidence Boundary From Failing Tests
|
||||
|
||||
**Files:**
|
||||
|
||||
- Create:
|
||||
`libs/ui/playback/src/lib/shaka-engine/shaka-error-contract.ts`
|
||||
- Create:
|
||||
`libs/ui/playback/src/lib/shaka-engine/shaka-playback-evidence.util.ts`
|
||||
- Create:
|
||||
`libs/ui/playback/src/lib/shaka-engine/shaka-playback-evidence.util.spec.ts`
|
||||
- Modify:
|
||||
`libs/ui/playback/src/lib/playback-diagnostics/playback-diagnostics.model.ts`
|
||||
- Modify:
|
||||
`libs/ui/playback/src/lib/shaka-engine/shaka-module.types.ts`
|
||||
|
||||
- [ ] **Step 1: Write the failing installed-runtime contract test**
|
||||
|
||||
In `shaka-playback-evidence.util.spec.ts`, load the real compiled package in a
|
||||
child process with `global.self = globalThis` and return:
|
||||
|
||||
```typescript
|
||||
interface InstalledShakaContract {
|
||||
readonly version: string;
|
||||
readonly severity: Readonly<Record<string, number>>;
|
||||
readonly category: Readonly<Record<string, number>>;
|
||||
readonly code: Readonly<Record<string, number>>;
|
||||
}
|
||||
```
|
||||
|
||||
Assert:
|
||||
|
||||
```typescript
|
||||
expect(installed.version).toBe(SHAKA_DIAGNOSTIC_VERSION);
|
||||
expect(installed.severity).toEqual(SHAKA_ERROR_SEVERITY);
|
||||
expect(installed.category).toEqual(SHAKA_ERROR_CATEGORY);
|
||||
for (const [name, value] of Object.entries(SHAKA_ERROR_CODE)) {
|
||||
expect(installed.code[name]).toBe(value);
|
||||
}
|
||||
```
|
||||
|
||||
Run:
|
||||
|
||||
```bash
|
||||
NODE_OPTIONS=--experimental-vm-modules node node_modules/jest/bin/jest.js \
|
||||
--config jest.web-esm.workspace.ts --runTestsByPath \
|
||||
libs/ui/playback/src/lib/shaka-engine/shaka-playback-evidence.util.spec.ts \
|
||||
--runInBand
|
||||
```
|
||||
|
||||
Expected: FAIL because the contract and evidence module do not exist.
|
||||
|
||||
- [ ] **Step 2: Add the minimal public model**
|
||||
|
||||
Add const-derived types to `playback-diagnostics.model.ts`:
|
||||
|
||||
```typescript
|
||||
export const ShakaPlaybackSeverity = {
|
||||
Recoverable: 'recoverable',
|
||||
Critical: 'critical',
|
||||
Unknown: 'unknown',
|
||||
} as const;
|
||||
|
||||
export const ShakaPlaybackCategory = {
|
||||
Network: 'network',
|
||||
Text: 'text',
|
||||
Media: 'media',
|
||||
Manifest: 'manifest',
|
||||
Streaming: 'streaming',
|
||||
Drm: 'drm',
|
||||
Player: 'player',
|
||||
Cast: 'cast',
|
||||
Storage: 'storage',
|
||||
Ads: 'ads',
|
||||
Unknown: 'unknown',
|
||||
} as const;
|
||||
|
||||
export const ShakaPlaybackDisposition = {
|
||||
Terminal: 'terminal',
|
||||
Recoverable: 'recoverable',
|
||||
} as const;
|
||||
|
||||
export const ShakaPlaybackStage = {
|
||||
Manifest: 'manifest',
|
||||
Segment: 'segment',
|
||||
Media: 'media',
|
||||
License: 'license',
|
||||
Unknown: 'unknown',
|
||||
} as const;
|
||||
|
||||
export const ShakaPlaybackFailure = {
|
||||
Network: 'network',
|
||||
Drm: 'drm',
|
||||
Manifest: 'manifest',
|
||||
Media: 'media',
|
||||
Unknown: 'unknown',
|
||||
} as const;
|
||||
|
||||
export const ShakaPlaybackUnknownCode = 'unknown' as const;
|
||||
|
||||
export interface ShakaPlaybackEvidence {
|
||||
readonly severity: ShakaPlaybackSeverity;
|
||||
readonly category: ShakaPlaybackCategory;
|
||||
readonly engineCode: number | typeof ShakaPlaybackUnknownCode;
|
||||
readonly disposition: ShakaPlaybackDisposition;
|
||||
readonly stage: ShakaPlaybackStage;
|
||||
readonly failure: ShakaPlaybackFailure;
|
||||
readonly httpStatus?: number;
|
||||
}
|
||||
```
|
||||
|
||||
Add `readonly shaka?: ShakaPlaybackEvidence` to `PlaybackDiagnostic`, and
|
||||
remove `message` from `ShakaErrorLike` so downstream Shaka code has no typed
|
||||
message access:
|
||||
|
||||
```typescript
|
||||
export interface ShakaErrorLike {
|
||||
severity: number;
|
||||
category: number;
|
||||
code: number;
|
||||
data?: readonly unknown[];
|
||||
}
|
||||
```
|
||||
|
||||
- [ ] **Step 3: Add the exact 5.2.2 public allowlist**
|
||||
|
||||
In `shaka-error-contract.ts`, export:
|
||||
|
||||
```typescript
|
||||
export const SHAKA_DIAGNOSTIC_VERSION = 'v5.2.2';
|
||||
export const SHAKA_ERROR_SEVERITY = {
|
||||
RECOVERABLE: 1,
|
||||
CRITICAL: 2,
|
||||
} as const;
|
||||
export const SHAKA_ERROR_CATEGORY = {
|
||||
NETWORK: 1,
|
||||
TEXT: 2,
|
||||
MEDIA: 3,
|
||||
MANIFEST: 4,
|
||||
STREAMING: 5,
|
||||
DRM: 6,
|
||||
PLAYER: 7,
|
||||
CAST: 8,
|
||||
STORAGE: 9,
|
||||
ADS: 10,
|
||||
} as const;
|
||||
```
|
||||
|
||||
Define `SHAKA_ERROR_CODE` with the exact active public Shaka 5.2.2 online
|
||||
playback codes from categories NETWORK through PLAYER, including the direct
|
||||
and nested HTTP codes, media and manifest codes, all DRM codes, and
|
||||
`LOAD_INTERRUPTED`. Do not include retired numeric gaps. The contract test
|
||||
must verify every name/value against the installed runtime.
|
||||
|
||||
- [ ] **Step 4: Write failing sanitizer and privacy tests**
|
||||
|
||||
Use the documented direct bad-status shape:
|
||||
|
||||
```typescript
|
||||
const raw = {
|
||||
severity: 1,
|
||||
category: 1,
|
||||
code: 1001,
|
||||
message: 'https://user:secret@provider.example/manifest.mpd',
|
||||
data: [
|
||||
'https://provider.example/manifest.mpd?token=secret',
|
||||
503,
|
||||
'provider body secret',
|
||||
{ Authorization: 'Bearer secret' },
|
||||
0,
|
||||
'https://provider.example/final?token=secret',
|
||||
],
|
||||
};
|
||||
```
|
||||
|
||||
Expect:
|
||||
|
||||
```typescript
|
||||
{
|
||||
severity: 'recoverable',
|
||||
category: 'network',
|
||||
engineCode: 1001,
|
||||
disposition: 'terminal',
|
||||
stage: 'unknown',
|
||||
failure: 'network',
|
||||
httpStatus: 503,
|
||||
}
|
||||
```
|
||||
|
||||
Add a nested `DRM + LICENSE_REQUEST_FAILED` shape whose `data[0]` is the same
|
||||
network error and whose remaining data contains license/session secrets.
|
||||
Expect only the nested status number to survive.
|
||||
|
||||
Cover:
|
||||
|
||||
- HTTP boundaries 99/100/599/600 and non-integers;
|
||||
- status-like values on non-documented codes remain absent;
|
||||
- unknown severity/category/code values become `unknown`;
|
||||
- mismatched public category/code pairs have `failure=unknown`;
|
||||
- no URL, message, header, body, key, license, credential, or arbitrary
|
||||
property survives `JSON.stringify(evidence)`;
|
||||
- exact manifest, segment, media, license, and unknown stages;
|
||||
- exact network, DRM, manifest, media, restrictions, and unknown failures.
|
||||
|
||||
- [ ] **Step 5: Implement the minimal sanitizer**
|
||||
|
||||
In `shaka-playback-evidence.util.ts`, expose:
|
||||
|
||||
```typescript
|
||||
export function createShakaPlaybackEvidence(
|
||||
error: Partial<ShakaErrorLike> | null | undefined,
|
||||
disposition: ShakaPlaybackDisposition
|
||||
): ShakaPlaybackEvidence;
|
||||
```
|
||||
|
||||
Use only:
|
||||
|
||||
```typescript
|
||||
error?.severity;
|
||||
error?.category;
|
||||
error?.code;
|
||||
error?.data?.[1]; // exact direct BAD_HTTP_STATUS only
|
||||
error?.data?.[0]; // exact documented nested DRM network error only
|
||||
```
|
||||
|
||||
Build severity/category/code through exact sets, derive stage/failure through
|
||||
exact category/code pairs, and return a fresh flat evidence object. Do not
|
||||
read or serialize any other field.
|
||||
|
||||
Run the focused spec again.
|
||||
|
||||
Expected: PASS.
|
||||
|
||||
### Task 2: Drive Exact Classification And Shared Diagnostic Retention
|
||||
|
||||
**Files:**
|
||||
|
||||
- Modify:
|
||||
`libs/ui/playback/src/lib/shaka-engine/shaka-error-classifier.spec.ts`
|
||||
- Modify:
|
||||
`libs/ui/playback/src/lib/shaka-engine/shaka-error-classifier.ts`
|
||||
- Modify:
|
||||
`libs/ui/playback/src/lib/playback-diagnostics/playback-diagnostics.util.ts`
|
||||
|
||||
- [ ] **Step 1: Replace heuristic expectations with failing exact-code tests**
|
||||
|
||||
Change the classifier API to:
|
||||
|
||||
```typescript
|
||||
classifyShakaPlaybackIssue(
|
||||
error,
|
||||
metadata,
|
||||
disposition
|
||||
): PlaybackDiagnostic | null;
|
||||
```
|
||||
|
||||
Add expectations:
|
||||
|
||||
```text
|
||||
NETWORK + BAD_HTTP_STATUS -> network-error
|
||||
DRM + REQUESTED_KEY_SYSTEM_CONFIG_UNAVAILABLE -> drm-or-encryption
|
||||
MANIFEST + DASH_NO_COMMON_KEY_SYSTEM -> drm-or-encryption
|
||||
MANIFEST + DASH_INVALID_XML -> unknown-playback-error
|
||||
MANIFEST + DASH_UNSUPPORTED_CONTAINER -> unsupported-container
|
||||
MANIFEST + CONTENT_UNSUPPORTED_BY_BROWSER -> unknown-playback-error
|
||||
MEDIA + MEDIA_SOURCE_OPERATION_FAILED -> media-decode-error
|
||||
MANIFEST + RESTRICTIONS_CANNOT_BE_MET -> unknown-playback-error
|
||||
mismatched category/code -> unknown-playback-error
|
||||
unknown values -> unknown-playback-error
|
||||
recoverable disposition -> null
|
||||
```
|
||||
|
||||
Put misleading `message` and `data` strings such as `CORS codec license`
|
||||
alongside unknown or mismatched structured values and prove they do not change
|
||||
classification.
|
||||
|
||||
Run the focused classifier spec.
|
||||
|
||||
Expected: FAIL against the current category/message heuristic classifier.
|
||||
|
||||
- [ ] **Step 2: Implement exact classification**
|
||||
|
||||
Create evidence first:
|
||||
|
||||
```typescript
|
||||
const evidence = createShakaPlaybackEvidence(error, disposition);
|
||||
if (evidence.disposition === ShakaPlaybackDisposition.Recoverable) {
|
||||
return null;
|
||||
}
|
||||
```
|
||||
|
||||
Select the top-level code only from exact evidence:
|
||||
|
||||
```typescript
|
||||
network -> NetworkError
|
||||
drm -> DrmOrEncryption
|
||||
DASH_UNSUPPORTED_CONTAINER -> UnsupportedContainer
|
||||
MEDIA_SOURCE_OPERATION_FAILED -> MediaDecodeError
|
||||
MEDIA_SOURCE_OPERATION_THREW -> MediaDecodeError
|
||||
VIDEO_ERROR -> MediaDecodeError
|
||||
everything else -> UnknownPlaybackError
|
||||
```
|
||||
|
||||
Call `createPlaybackDiagnostic` with `httpStatus` and `shaka`, but no raw
|
||||
`details` or native message.
|
||||
|
||||
Extend `createPlaybackDiagnostic` to accept and retain:
|
||||
|
||||
```typescript
|
||||
readonly shaka?: ShakaPlaybackEvidence;
|
||||
```
|
||||
|
||||
Run the focused evidence and classifier specs.
|
||||
|
||||
Expected: PASS.
|
||||
|
||||
- [ ] **Step 3: Sanitize the pre-engine DRM diagnostic**
|
||||
|
||||
Change `createUnsupportedDrmDiagnostic` to ignore the provider-supplied
|
||||
license string in technical details:
|
||||
|
||||
```typescript
|
||||
details: 'Unsupported DRM license configuration';
|
||||
```
|
||||
|
||||
Add a secret-bearing license string test and prove the diagnostic JSON and
|
||||
details omit it while the top-level code remains `drm-or-encryption` and
|
||||
external fallback remains disabled.
|
||||
|
||||
### Task 3: Drive Session Lifecycle And Adapter Routing
|
||||
|
||||
**Files:**
|
||||
|
||||
- Modify:
|
||||
`libs/ui/playback/src/lib/shaka-engine/shaka-video-session.spec.ts`
|
||||
- Modify:
|
||||
`libs/ui/playback/src/lib/shaka-engine/shaka-video-session.ts`
|
||||
- Modify:
|
||||
`libs/ui/playback/src/lib/shaka-engine/shaka-player-test-double.ts`
|
||||
- Modify:
|
||||
`libs/ui/playback/src/lib/art-player/art-player-source-session.dash.spec.ts`
|
||||
|
||||
- [ ] **Step 1: Write failing recoverable/terminal routing tests**
|
||||
|
||||
Add session regressions for:
|
||||
|
||||
```text
|
||||
recoverable Player#error -> no diagnostic, same current player
|
||||
unknown-severity Player#error -> no diagnostic, same current player
|
||||
critical Player#error -> one terminal diagnostic, player destroyed
|
||||
recoverable-severity load rejection -> one terminal diagnostic
|
||||
critical event during stalled load -> one diagnostic, later interruption ignored
|
||||
module-loader Error with URL/token -> terminal unknown evidence without message
|
||||
```
|
||||
|
||||
For the terminal rejected `BAD_HTTP_STATUS`, expect:
|
||||
|
||||
```typescript
|
||||
expect(issue.shaka).toEqual({
|
||||
severity: 'recoverable',
|
||||
category: 'network',
|
||||
engineCode: 1001,
|
||||
disposition: 'terminal',
|
||||
stage: 'unknown',
|
||||
failure: 'network',
|
||||
httpStatus: 503,
|
||||
});
|
||||
```
|
||||
|
||||
Run:
|
||||
|
||||
```bash
|
||||
NODE_OPTIONS=--experimental-vm-modules node node_modules/jest/bin/jest.js \
|
||||
--config jest.web-esm.workspace.ts --runTestsByPath \
|
||||
libs/ui/playback/src/lib/shaka-engine/shaka-video-session.spec.ts \
|
||||
--runInBand
|
||||
```
|
||||
|
||||
Expected: FAIL because the current session suppresses only event severity,
|
||||
passes arbitrary messages on rejection, and has no structured disposition.
|
||||
|
||||
- [ ] **Step 2: Implement route-owned disposition**
|
||||
|
||||
In `ShakaVideoSession`:
|
||||
|
||||
- call the classifier with `Terminal` for module rejection, unsupported
|
||||
browser support, and `load()` rejection;
|
||||
- call it with `Recoverable` for exact recoverable events and emit nothing
|
||||
when it returns null;
|
||||
- call it with `Terminal` only for exact critical events;
|
||||
- ignore unknown-severity events;
|
||||
- suppress interruption only for the exact
|
||||
`CRITICAL + PLAYER + LOAD_INTERRUPTED` triple;
|
||||
- remove `toErrorMessage` and every Shaka message fallback;
|
||||
- tear down only after a non-null terminal diagnostic.
|
||||
|
||||
Run the focused session spec.
|
||||
|
||||
Expected: PASS.
|
||||
|
||||
- [ ] **Step 3: Write and pass the ArtPlayer adapter regression**
|
||||
|
||||
Configure the fake Shaka player's load promise to reject with a documented
|
||||
bad-status shape, pass `emitPlaybackIssue` into
|
||||
`ArtPlayerSourceSession`, invoke the `mpd` custom type, and expect one
|
||||
diagnostic with:
|
||||
|
||||
```typescript
|
||||
{
|
||||
source: PlaybackDiagnosticSource.Shaka,
|
||||
player: InlinePlaybackPlayer.ArtPlayer,
|
||||
code: PlaybackDiagnosticCode.NetworkError,
|
||||
httpStatus: 503,
|
||||
shaka: expect.objectContaining({
|
||||
engineCode: 1001,
|
||||
disposition: 'terminal',
|
||||
}),
|
||||
}
|
||||
```
|
||||
|
||||
Prove the response body/header/token sentinel is absent from serialized
|
||||
diagnostic data other than the pre-existing active `sourceUrl`.
|
||||
|
||||
### Task 4: Drive Safe Rendered Technical Details
|
||||
|
||||
**Files:**
|
||||
|
||||
- Modify:
|
||||
`libs/ui/playback/src/lib/web-player-view/web-player-view.component.spec.ts`
|
||||
- Modify:
|
||||
`libs/ui/playback/src/lib/web-player-view/web-player-view-diagnostics.utils.ts`
|
||||
|
||||
- [ ] **Step 1: Write the failing rendered-detail regression**
|
||||
|
||||
Create a Shaka diagnostic with safe evidence plus malicious legacy fields:
|
||||
|
||||
```typescript

|
||||
|
||||
### Task 5: Documentation, Release Note, And Full Validation
|
||||
|
||||
**Files:**
|
||||
|
||||
- Modify: `docs/architecture/embedded-inline-playback.md`
|
||||
- Modify: `docs/architecture/m3u-playlist-module.md`
|
||||
- Modify: `CLAUDE.md`
|
||||
- Modify: `AGENTS.md`
|
||||
- Create: `.changes/playback-structured-shaka-diagnostics.md`
|
||||
|
||||
- [ ] **Step 1: Update canonical documentation**
|
||||
|
||||
Document:
|
||||
|
||||
- Shaka 5.2.2 public version lock;
|
||||
- evidence fields and rejected raw fields;
|
||||
- direct and nested documented HTTP status layouts;
|
||||
- exact failure/stage classification and ambiguous unknown cases;
|
||||
- recoverable event versus terminal load-rejection semantics;
|
||||
- sanitized technical detail output;
|
||||
- unchanged source routing, ClearKey fallback rule, and VOD failover.
|
||||
|
||||
Keep the high-level Shaka summaries in `CLAUDE.md` and `AGENTS.md`
|
||||
consistent.
|
||||
|
||||
- [ ] **Step 2: Add the user-facing release note**
|
||||
|
||||
Create:
|
||||
|
||||
```markdown
|
||||
---
|
||||
type: fix
|
||||
area: playback
|
||||
---
|
||||
|
||||
Shaka playback errors now use exact engine evidence, keep recoverable retries from becoming terminal diagnostics, and omit provider URLs, credentials, and response data from technical details.
|
||||
```
|
||||
|
||||
- [ ] **Step 3: Run focused and affected validation**
|
||||
|
||||
Run:
|
||||
|
||||
```bash
|
||||
NODE_OPTIONS=--experimental-vm-modules node node_modules/jest/bin/jest.js \
|
||||

|
||||
pnpm run release:notes:validate
|
||||
git diff --check
|
||||
```
|
||||
|
||||
Expected: every command exits 0.
|
||||
|
||||
- [ ] **Step 4: Complete the test-impact pass**
|
||||
|
||||
Confirm:
|
||||
|
||||
```text
|
||||
Affected project: ui-playback
|
||||
Unit/component coverage: required and run
|
||||
Lint: required and run
|
||||
Web typecheck: required and run
|
||||
i18n validation: required and run
|
||||
Release-note validation: required and run
|
||||
E2E: not required; no workflow, routing, player selection, or integration
|
||||
lifecycle changed, and event/rejection behavior is covered at the
|
||||
session plus ArtPlayer adapter boundaries
|
||||
```
|
||||
|
||||
### Task 6: Independent Review, Fixes, And Ready PR
|
||||
|
||||
**Files:**
|
||||
|
||||
- Review: complete diff from `origin/master` to branch HEAD
|
||||
|
||||
- [ ] **Step 1: Commit the implementation before review**
|
||||
|
||||
Create focused conventional commits for the evidence boundary/runtime change
|
||||
and documentation/release note. Confirm:
|
||||
|
||||
```bash
|
||||
git status --short
|
||||
git log --oneline origin/master..HEAD
|
||||
```
|
||||
|
||||
- [ ] **Step 2: Dispatch an independent local Codex review**
|
||||
|
||||
Give the reviewer:
|
||||
|
||||
```text
|
||||
Base: origin/master
|
||||
Head: branch HEAD
|
||||
Requirements: the structured Shaka design and this implementation plan
|
||||
Focus: actionable P0/P1/P2 correctness, privacy, public-contract drift,
|
||||
lifecycle duplication/suppression, classification accuracy, and tests
|
||||
```
|
||||
|
||||
Require a full-diff review. If the reviewer reports an issue, verify it
|
||||
against the installed Shaka 5.2.2 source before changing code.
|
||||
|
||||
- [ ] **Step 3: Fix confirmed findings through TDD**
|
||||
|
||||
For every confirmed P0/P1/P2:
|
||||
|
||||
1. add or tighten a regression test;
|
||||
2. run it and observe the expected failure;
|
||||
3. implement the minimal fix;
|
||||
4. rerun the focused test and affected suite;
|
||||
5. commit the fix.
|
||||
|
||||
- [ ] **Step 4: Repeat independent review**
|
||||
|
||||
Review the updated full diff from `origin/master`. Expected: no actionable
|
||||
P0/P1/P2 findings.
|
||||
|
||||
- [ ] **Step 5: Repeat the complete validation ladder**
|
||||
|
||||
Rerun every command from Task 5 Step 3 after the final review fix. Expected:
|
||||
all exit 0 with fresh output.
|
||||
|
||||
- [ ] **Step 6: Push and create a ready PR**
|
||||
|
||||
Push `agent/structured-shaka-diagnostics` and create a non-draft PR with:
|
||||
|
||||
```text
|
||||
Title: fix(playback): structure Shaka diagnostics
|
||||

|
||||
safe technical details
|
||||
Testing: list every fresh validation command and result
|
||||
```
|
||||
|

# Structured Shaka Diagnostics
|
||||
|
||||
## Context
|
||||
|
||||
PR #1314 stopped treating an ambiguous native `MediaError` as codec evidence
|
||||
and retained explicit HTTP evidence. PR #1316 added an allowlisted hls.js
|
||||
boundary for HTML5 and ArtPlayer. PR #1317 added an allowlisted Video.js/VHS
|
||||
boundary for the default player. Shaka remains the only web source engine that
|
||||
copies an arbitrary message and serialized `error.data` into a diagnostic.
|
||||
|
||||
The locked workspace installs Shaka Player `5.2.2`. The audit used the
|
||||
installed package's public declarations, `shaka.util.Error` JSDoc, compiled
|
||||
runtime exports, and the load/error paths in the installed source. The public
|
||||
runtime reports:
|
||||
|
||||
- `shaka.Player.version === "v5.2.2"`;
|
||||
- severity values `RECOVERABLE=1` and `CRITICAL=2`;
|
||||
- category values `NETWORK=1`, `TEXT=2`, `MEDIA=3`, `MANIFEST=4`,
|
||||
`STREAMING=5`, `DRM=6`, `PLAYER=7`, `CAST=8`, `STORAGE=9`, and `ADS=10`;
|
||||
- numeric `shaka.util.Error.Code` values documented by the installed public
|
||||
API.
|
||||
|
||||
The existing `ShakaVideoSession` binds the public `Player#error` event before
|
||||
calling `load()`, and also observes the public `load()` rejection. Those paths
|
||||
have different terminal meaning and must not be collapsed into a
|
||||
severity-only gate.
|
||||
|
||||
## Goals
|
||||
|
||||
- Convert Shaka errors into a minimal allowlisted `ShakaPlaybackEvidence`
|
||||
value before classification or UI rendering.
|
||||
- Retain only validated public severity, category, and code values, an
|
||||
explicit lifecycle disposition, a code-proven stage/failure kind, and a
|
||||
documented HTTP status.
|
||||
- Classify only exact Shaka 5.2.2 category/code pairs.
|
||||
- Keep insufficient or inconsistent evidence unknown.
|
||||
- Keep recoverable player events from becoming terminal IPTVnator
|
||||
diagnostics.
|
||||
- Treat a rejected `Player.load()` as terminal even when the final public
|
||||
Shaka error still carries `RECOVERABLE`.
|
||||
- Prevent messages, URLs, headers, bodies, license/key payloads, credentials,
|
||||
and arbitrary objects from reaching stored or rendered diagnostics.
|
||||
- Version-lock the allowlist and tests to the installed Shaka public API.
|
||||
|
||||
## Non-goals
|
||||
|
||||
- Changing hls.js or Video.js/VHS evidence contracts.
|
||||
- Redesigning mpegts.js diagnostics.
|
||||
- Adding top-level diagnostic codes, history, persistence, correlation,
|
||||
probes, automatic engine failover, or a cross-player recommendation matrix.
|
||||
- Inspecting Shaka private loaders, networking state, parser internals, or
|
||||
retry counters.
|
||||
- Changing VOD multi-source auto-failover.
|
||||
- Inferring CORS, codec, DRM, container, or stage from message text.
|
||||
|
||||
## Approaches Considered
|
||||
|
||||
### Public error boundary with lifecycle disposition (selected)
|
||||
|
||||
Normalize the public `severity`, `category`, `code`, and only the documented
|
||||
HTTP-status slot into `ShakaPlaybackEvidence`. The session supplies
|
||||
`recoverable` for a recoverable event and `terminal` for a critical event or a
|
||||
rejected load. Classification and technical details accept only the sanitized
|
||||
evidence.
|
||||
|
||||
This preserves the strongest stable facts while making unsafe fields
|
||||
structurally unavailable to downstream code. It also represents the important
|
||||
case where Shaka's final network error remains severity-recoverable but the
|
||||
load promise has terminated.
|
||||
|
||||
### Severity-only event and rejection gate
|
||||
|
||||
Suppressing every `severity=RECOVERABLE` error would hide a terminal manifest
|
||||
load failure after Shaka exhausts retries. Treating every error as terminal
|
||||
would tear down a player that Shaka is still recovering. The route that
|
||||
delivers the error is therefore required evidence.
|
||||
|
||||
### Inspect request/parser internals
|
||||
|
||||
Private networking and parser state could reveal request types and richer
|
||||
stages, but it also exposes URLs, headers, response data, license payloads, and
|
||||
unstable implementation details. This is rejected by the privacy and public
|
||||
contract requirements.
|
||||
|
||||
### Stop after the audit
|
||||
|
||||
Stopping would be correct if the public API could not distinguish safe facts
|
||||
or terminal lifecycle. The installed API exposes exact enums, documented
|
||||
status layouts, and distinct event/rejection semantics, so a stable focused
|
||||
improvement is available.
|
||||
|
||||
## Installed Runtime And Event Ordering
|
||||
|
||||
Shaka 5.2.2 documents recoverable severity as an error from which the player
|
||||
is attempting to recover. It explicitly warns that some media-segment retry
|
||||
paths may never escalate to a critical error.
|
||||
|
||||
The installed runtime orders errors as follows:
|
||||
|
||||
1. `PreloadManager.onError()` rejects its success promise for a critical
|
||||
error, destroys preload work, and synchronously dispatches the public
|
||||
`error` event.
|
||||
2. The existing session's event listener therefore observes that critical
|
||||
event before the `await player.load()` continuation handles the rejection.
|
||||
3. Session teardown changes the current-player identity; the later rejection
|
||||
is ignored, preventing a duplicate diagnostic.
|
||||
4. Direct manifest/parser failures can reject the preload/load promise without
|
||||
dispatching a player error. The load-rejection path must classify them.
|
||||
5. The networking engine retries errors while their public severity is
|
||||
recoverable. When attempts are exhausted it throws the last error without
|
||||
rewriting its severity. A rejected `load()` is therefore terminal by
|
||||
lifecycle even if evidence says `severity=recoverable`.
|
||||
6. A recoverable public player event is not terminal and must leave the
|
||||
current engine attached.
|
||||
|
||||
`LOAD_INTERRUPTED` is suppressed only when the exact public triple is
|
||||
`CRITICAL + PLAYER + LOAD_INTERRUPTED`; an arbitrary object containing the
|
||||
number `7000` is not enough.
|
||||
|
||||
## Version-locked Public Contract
|
||||
|
||||
The production allowlist contains the exact Shaka 5.2.2 severity/category
|
||||
values and the public online-playback error codes used by the boundary. A
|
||||
contract test loads the installed compiled package in a child Node process,
|
||||
asserts `v5.2.2`, compares the full severity/category maps, and verifies every
|
||||
allowlisted code name/value against `shaka.util.Error.Code`.
|
||||
|
||||
The explicit version assertion makes a dependency upgrade fail before new or
|
||||
changed codes are silently accepted. An upgrade requires reviewing the new
|
||||
public JSDoc layouts and lifecycle before updating the lock.
|
||||
|
||||
## Evidence Contract
|
||||
|
||||
`ShakaPlaybackEvidence` contains:
|
||||
|
||||
- `severity`: `recoverable`, `critical`, or `unknown`;
|
||||
- `category`: one validated public category name in lowercase, otherwise
|
||||
`unknown`;
|
||||
- `engineCode`: one allowlisted public numeric code, otherwise `unknown`;
|
||||
- `disposition`: `terminal` or `recoverable`, supplied by the session route;
|
||||
- `stage`: `manifest`, `segment`, `media`, `license`, or `unknown`;
|
||||
- `failure`: `network`, `drm`, `manifest`, `media`, or `unknown`;
|
||||
- optional `httpStatus`: an integer from 100 through 599.
|
||||
|
||||
The boundary does not retain:
|
||||
|
||||
- `error.message`;
|
||||
- arbitrary or serialized `error.data`;
|
||||
- request, redirect, manifest, segment, license, or certificate URLs;
|
||||
- request or response headers;
|
||||
- response text, bodies, or binary data;
|
||||
- browser exceptions and events;
|
||||
- DRM session metadata, keys, licenses, provider payloads, or credentials;
|
||||
- unknown object properties.
|
||||
|
||||
The existing `PlaybackDiagnostic.sourceUrl` remains the active source metadata
|
||||
used by Retry, Copy URL, explicit external-player actions, and the existing VOD
|
||||
failover flow. No URL is copied from a Shaka error.
|
||||
|
||||
## HTTP Status Extraction
|
||||
|
||||
Shaka 5.2.2 publicly documents:
|
||||
|
||||
- `BAD_HTTP_STATUS` (`NETWORK`, code `1001`): `error.data[1]` is the status;
|
||||
- `LICENSE_REQUEST_FAILED` (`DRM`, code `6007`): `error.data[0]` is a nested
|
||||
Shaka networking error;
|
||||
- `SERVER_CERTIFICATE_REQUEST_FAILED` (`DRM`, code `6017`):
|
||||
`error.data[0]` is a nested Shaka networking error.
|
||||
|
||||
The boundary reads a status only from an exact `NETWORK + BAD_HTTP_STATUS`
|
||||
shape, directly or through those two exact documented nested-error layouts.
|
||||
It validates the integer protocol range and copies only the number. Status-like
|
||||
values in any other data position or arbitrary object are ignored.
|
||||
|
||||
## Failure And Stage Mapping
|
||||
|
||||
Failure uses exact category/code pairs:
|
||||
|
||||
- allowlisted online network codes in the `NETWORK` category → `network`;
|
||||
- allowlisted DRM codes in the `DRM` category → `drm`;
|
||||
- exact manifest encryption/key-system codes → `drm`;
|
||||
- exact media codes in the `MEDIA` category → `media`;
|
||||
- exact manifest/parsing codes in the `MANIFEST` category → `manifest`;
|
||||
- `DASH_UNSUPPORTED_CONTAINER` and
|
||||
`CONTENT_UNSUPPORTED_BY_BROWSER` → `media`, because the public descriptions
|
||||
prove a media support failure but the latter does not distinguish container
|
||||
from codec;
|
||||
- inconsistent category/code pairs, internal/test-only ambiguity, and
|
||||
`RESTRICTIONS_CANNOT_BE_MET` → `unknown`.
|
||||
|
||||
Stage is narrower than failure:
|
||||
|
||||
- exact manifest codes → `manifest`;
|
||||
- exact segment/index/init parsing codes and `SEGMENT_MISSING` → `segment`;
|
||||
- exact MediaSource/video pipeline codes → `media`;
|
||||
- exact license request/response/server-selection/expiry codes → `license`;
|
||||
- everything else → `unknown`.
|
||||
|
||||
Messages and arbitrary data never affect either value.
|
||||
|
||||
## User-facing Classification
|
||||
|
||||
No new top-level diagnostic code is needed:
|
||||
|
||||
1. `failure=network` → `network-error`.
|
||||
2. `failure=drm` → `drm-or-encryption`.
|
||||
3. Exact `DASH_UNSUPPORTED_CONTAINER` →
|
||||
`unsupported-container`.
|
||||
4. Exact MediaSource operation or video-element failure codes that identify
|
||||
the media pipeline → `media-decode-error`.
|
||||
5. Manifest parsing, generic media parsing/transformation, ambiguous
|
||||
browser-content support, restrictions, unknown values, and inconsistent
|
||||
pairs → `unknown-playback-error`.
|
||||
|
||||
Shaka 5.2.2 has no exact public code that distinguishes an unsupported codec
|
||||
from an unsupported container for the generic
|
||||
`CONTENT_UNSUPPORTED_BY_BROWSER` case. It therefore remains unknown instead of
|
||||
becoming a false codec or container diagnosis. No Shaka path emits
|
||||
`browser-access-error` without a structured public access code.
|
||||
|
||||
## Session And Adapter Flow
|
||||
|
||||
`ShakaVideoSession` owns disposition:
|
||||
|
||||
- module-load rejection, unsupported browser capability, and `load()`
|
||||
rejection are terminal;
|
||||
- a public error event is terminal only for the exact critical severity;
|
||||
- a recoverable event is passed through the shared evidence/classifier gate,
|
||||
returns no diagnostic, and leaves the player attached;
|
||||
- an event with unknown severity is ignored because terminal state is not
|
||||
proven;
|
||||
- a terminal diagnostic tears down the engine once;
|
||||
- ClearKey sources keep the existing rule that external fallback is
|
||||
unavailable because the external player never receives key configuration.
|
||||
|
||||
HTML5 and ArtPlayer keep their current Shaka session adapters. The structured
|
||||
diagnostic travels through their existing `emitPlaybackIssue` callbacks; no
|
||||
player-selection, source-selection, or VOD failover behavior changes.
|
||||
|
||||
Unsupported playlist DRM remains a pre-engine app diagnostic, but its
|
||||
technical detail becomes a fixed safe description instead of echoing the
|
||||
provider-supplied license string.
|
||||
|
||||
## User Interface
|
||||
|
||||
The existing technical “Error details” row renders only
|
||||
`ShakaPlaybackEvidence`, for example:
|
||||
|
||||
`stage=unknown · failure=network · severity=recoverable · category=network · code=1001 · disposition=terminal · HTTP 503`
|
||||
|
||||
When structured Shaka evidence exists, legacy `details` and native message
|
||||
fields are ignored even if a caller accidentally supplies them. Existing
|
||||
titles, descriptions, HTTP badge, Retry, Copy URL, explicit MPV/VLC actions,
|
||||
and layout remain unchanged. No translation or visual styling change is
|
||||
required.
|
||||
|
||||
## Testing
|
||||
|
||||
Use test-driven development:
|
||||
|
||||
- Compare the allowlist/version with the real installed Shaka 5.2.2 runtime.
|
||||
- Exercise real documented direct and nested HTTP error shapes.
|
||||
- Prove all unsafe data fields and misleading messages are excluded.
|
||||
- Cover exact network, DRM, manifest, container, media, restrictions,
|
||||
mismatched, and unknown classification.
|
||||
- Prove recoverable classification returns no terminal diagnostic.
|
||||
- Prove a recoverable-severity load rejection is terminal by lifecycle.
|
||||
- Prove recoverable and unknown-severity events leave the session running.
|
||||
- Prove a critical event during an in-flight load emits once and teardown does
|
||||
not duplicate the later rejection.
|
||||
- Cover ClearKey fallback suppression and ArtPlayer adapter routing.
|
||||
- Prove the rendered detail row uses only sanitized Shaka evidence.
|
||||
|
||||
Run the complete `ui-playback` unit target, its lint target, web typecheck,
|
||||
i18n validation, release-note validation, and the repository test-impact pass.
|
||||
No E2E is required because the player workflow, controls, source routing, and
|
||||
integration lifecycle are unchanged; the event/rejection semantics are
|
||||
covered at the session and adapter boundaries.
|
||||
|
||||
## Documentation And Release Note
|
||||
|
||||
Update `docs/architecture/embedded-inline-playback.md` as the canonical
|
||||
browser diagnostic contract and the Shaka engine section in
