The public docs/assets/js/vconsole.min.js URL remains vConsole 3.15.0 with a local lifecycle correction. upstream.js is the exact npm distribution bundle: SHA-256 671f47427e1e3048919147c765e9fb71e4ea40d79a8c2829089f499d3e9b9bf4. The archive identity and upstream LICENSE are pinned in ../manifest.json. Reference source is Tencent/vConsole commit 05d80398bae35e793774f74e3c052b4e530e293a (tag v3.15.0): src/log/log.model.ts, src/core/core.ts, and src/component/recycleScroller/recycleScroller.svelte.

Ownership and build

lifecycle.ts owns queued log frames. Removing the last log plugin invalidates the ticket before cancellation, clears its queue/flag, and restores console even when cancellation throws. A late cancelled callback cannot consume a new queue on the reused singleton log model. Ordinary batches retain order and release their flag before flushing, including reentrant logging.
The same helper schedules panel insertion against the original instance and plugin object. Removed or replaced plugins cannot populate a new same-ID tab.
build.ts verifies the whole upstream SHA and six unique insertion points. It adds the private helper inside the existing UMD factory, replaces log scheduling/unbinding and panel insertion, and guards two virtual-scroller continuations after their timers. Svelte sets the bound items element to null on destroy; those continuations return before touching removed DOM.
../../build-vconsole.mjs (scripts/build-vconsole.mjs from the root) is the CLI. TypeScript and esbuild are existing root dev dependencies. The helper is emitted as ES5; it uses an array rather than requiring WeakMap before the upstream bundle installs its own polyfills. The remaining vendor code, CSS and UMD branch selection are retained byte for byte.

Run yarn build:vconsole after editing the helper or reviewed patch hooks, then update the candidate fingerprint in ../manifest.json and refactor/third-party.json with the validation evidence. Run yarn build:site-notices. yarn check:vconsole is read-only and rejects output drift; it does not update the frozen upstream or bless arbitrary vendor changes. CI checks generation before notices and rebuilds the patch before notice output. Never hand-edit the generated minified file.

Validation and limits

yarn test:vconsole covers queue order, reentrancy, cancellation exceptions, late callbacks, panel ownership, upstream drift and deterministic generation. yarn test:browser test/browser/vconsole-lifecycle.spec.js test/browser/site-vendor.spec.js --workers=1 covers real browser globals, named AMD, CommonJS factory loading, visible logs, immediate destroy/recreate, same-ID plugin replacement, pending scroller layout, and the actual mobile page playing local media. Setting ARTPLAYER_VCONSOLE_BASELINE=1 serves the frozen original only in the lifecycle test to reproduce failures; normal CI serves the candidate and expects no errors. The scroller case holds zero-delay timers to force the late continuation while using native rendering, ResizeObserver and RAF; this is explicit fault injection.

This patch does not claim complete upstream lifecycle coverage, device coverage, or permission clearance. The upstream LICENSE is distributed verbatim, but its missing MIT body and bundled dependency notices remain open in VENDOR-07/SITE-07. Do not replace or upgrade the bundle to resolve these issues without separately checking entrypoints, logging, CSS and the full dependency notices.
