+# Speedometer 3.1 pinned pack: redistribution audit
+
+## Decision
+
+**Do not redistribute the complete pinned archive yet.** The top-level BSD-style license permits redistribution of Speedometer's own work when its notice, conditions, and disclaimer travel with it. It does not establish rights for every embedded work. The pinned archive contains identifiable third-party material whose grant or compliance path is not yet established. This is a source audit, not a legal opinion or a benchmark run.
+
+Source: [WebKit/Speedometer commit `1386415be8fef2f6b6bbdbe1828872471c5d802a`](https://github.com/WebKit/Speedometer/tree/1386415be8fef2f6b6bbdbe1828872471c5d802a), [root license](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/LICENSE).
+
+## Exact inventory
+
+The companion [per-file manifest](speedometer-license-manifest.tsv) records every relative path, byte count, SHA-256, and **review group** in the full GitHub commit archive: **1,118 files; 61,022,359 uncompressed bytes**. Its SHA-256 is `78edcd45649128fbd4c8659c1d054a2b9bb76a184b58ce59b37895c19f2bdfb6`. The archive download SHA-256 was `cfefa818d7789ed2f2b9f3f1bf608cc35e4e8241489eef47049296ce92791313`. Review groups flag provenance work; they are **not license determinations**. The complete source archive is a conservative candidate pack, not a selected minimum runtime file set.
+
+Reproduce the manifest from that commit's GitHub `.tar.gz`: strip its single leading directory; sort regular-file paths by UTF-8 path; for each file write `path`, decimal byte count, lowercase SHA-256, and review group as tab-separated fields. Group rules: exact notice names and `*.LICENSE.txt`/`3rdpartylicenses.txt` first; then Gutenberg HTML, chart datasets, all news-site files, Adobe icon SVGs, then TodoMVC, React Stockcharts, charts, editors, and remainder in that order. The manifest itself is not an upstream artifact.
+
+Nine separate notice files appear in the archive: `LICENSE`; `resources/todomvc/license.md`; `resources/react-stockcharts/build/static/js/2.8e539c84.chunk.js.LICENSE.txt`; Angular and Angular Complex `dist/3rdpartylicenses.txt`; and React, React Complex, React Redux, React Redux Complex `dist/app.bundle.js.LICENSE.txt`. Exact paths and hashes are in the manifest. Inline notices in JavaScript, CSS, HTML, SVG, and source maps also need preservation. A filename scan cannot prove all component notices were extracted.
+
+## Established obligations and specific gaps
+
+| Material | Evidence and current finding | Required action before shipping |
+| --- | --- | --- |
+| Speedometer-owned source | [Root license](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/LICENSE) requires retention of copyright, conditions, and disclaimer for source; reproduction in documentation or other materials for binary form. | Include root `LICENSE` in pack and distribution materials; keep original headers. |
+| TodoMVC implementations | [TodoMVC subtree license](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/todomvc/license.md) says MIT **unless otherwise specified**. Generated React and Angular notices identify further components. | Carry subtree license and all bundled notices. Audit each runtime bundle against its dependency versions; fill missing texts/attributions. |
+| Angular bundles | Both [`3rdpartylicenses.txt` files](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/todomvc/architecture-examples/angular/dist/3rdpartylicenses.txt) include MIT, Apache-2.0, and CC-BY-4.0 material. | Keep both files with their matching bundles; map each named component to bundle; satisfy Apache notice/change rules and CC attribution requirements as applicable. |
+| React Stockcharts | Its [README](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/react-stockcharts/README.md) claims MIT and points to upstream; [bundle notice](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/react-stockcharts/build/static/js/2.8e539c84.chunk.js.LICENSE.txt) lists dependencies. | Include upstream MIT text plus bundled notice; verify the actual bundled versions. |
+| News-site template and CSS | Both [Next README](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/newssite/news-next/README.md) and [Nuxt README](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/newssite/news-nuxt/README.md) credit [`flashdesignory/news-site-template`](https://github.com/flashdesignory/news-site-template). Its repository has no visible license file, and [its package metadata](https://github.com/flashdesignory/news-site-template/blob/main/package.json) declares none. Pinned [news-site-css metadata](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/newssite/news-site-css/package.json) says ISC but does not provide that license text. The source and exported `dist` include adapted template material. **No redistribution grant established for the template.** | Get written permission or a verifiable applicable license from its rights holder, or remove/replace the NewsSite suites and all dependent files. Obtain and carry correct ISC text/notice for news-site-css. Reassess suite set and scoring if suites removed. |
+| Chart datasets | [Dataset README](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/charts/datasets/README) identifies two CSVs copied from an older D3 path. It does not state their data source or rights. `airports.csv`, `flights-airports.csv`, and the README are the three manifest paths. Generated `resources/charts/dist/assets/flights-airports-9a9e6422.js` embeds data. | Trace dataset origin and grant, then include required attribution. Otherwise replace with licensed/synthetic data and rebuild the affected chart assets, or omit that workload. |
+| Adobe Spectrum icons and CSS | [Big DOM README](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/todomvc/big-dom-generator/README.md) says static shell uses Adobe `@spectrum-css`. Its source contains 22 `Smock_*.svg` icons plus three other SVGs, with no per-file notice. Generated `dist` and complex TodoMVC pages may embed this material. TodoMVC's MIT default alone cannot establish rights over Adobe assets. | Identify exact Adobe package/source and applicable icon/CSS license, preserve its notice, and verify built copies. If unavailable, replace assets and rebuild/verify affected pages. |
+| Editor text | [`longtext.html`](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/editors/assets/longtext.html) is Project Gutenberg eBook 2650 per [asset README](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/editors/assets/README.md). It includes Gutenberg branding and full license. [Gutenberg terms](https://www.gutenberg.org/policy/license) impose access, notice, format, fee, and territorial conditions while branding remains. | Preserve full embedded license and prominent notice; assess distribution geography and price. Simpler path: replace with separately cleared text of equivalent workload shape. |
+| Other generated bundles and imagery | Charts, Editors, NewsSite, TodoMVC, React Stockcharts, images, maps, and CSS are generated or embedded works. Package lock entries identify dependencies but do not themselves provide all license texts; absence of a notice file is not proof of permission. | Build a component-to-file bill of materials from pinned locks/source maps and licenses. Review all shipped binaries/images individually; acquire missing grants or exclude/rebuild. |
+
+## Pack gate
+
+1. Define exact runtime file set; leave development files out only after proving every enabled suite resolves locally. Record each shipped file in a final manifest, with source commit and byte hash. The full-archive manifest here remains comparison baseline.
+2. Map every final file to originating project or generated bundle components. Record SPDX identifier, copyright holder, evidence URL, required notice text, and fulfillment location. Mark unknown explicitly; no implicit root-license inheritance for third-party work.
+3. Resolve the specific gaps above. Carry all nine existing notice files when their associated files ship; carry missing upstream notices and keep inline notices. Build a top-level `THIRD_PARTY_NOTICES` index with bundled texts or direct accompanying files.
+4. Recheck after any exclusion, replacement, or rebuild. Any changed byte needs a new manifest digest and runtime validation. License clearance and offline functional validation are separate gates.
+
+The earlier [offline pack research](speedometer-offline-pack.md) established static-path plausibility and proposed blocked-network validation; it did not clear redistribution rights. No benchmark, browser installation, or host change was made here.

+# Speedometer 3.1 offline pack at the pinned upstream commit
+
+## Decision-ready finding
+
+The pinned [WebKit/Speedometer commit `1386415be8fef2f6b6bbdbe1828872471c5d802a`](https://github.com/WebKit/Speedometer/commit/1386415be8fef2f6b6bbdbe1828872471c5d802a) is a plausible source for an Odin **versioned browser workload** served from localhost. It contains built static applications and the benchmark runner. Its page identifies itself as Speedometer **3.1**, although `package.json` still says `3.0.0-alpha`; identify the pack by the full commit and a content digest, not that package version. The [about page](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/about.html) says workloads are built as static files and cannot depend on server infrastructure. The [runner](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/benchmark-runner.mjs) loads each suite in an iframe under `resources/`.
+
+This is a **conditional yes** for an offline pack. Source inspection and static link checks support completeness, but they do not prove that a browser makes no external requests or that every workload succeeds without internet. Require a blocked-network browser smoke test before calling the pack offline-ready. This research did not execute a benchmark or install a browser.
+
+## Pack contents and static checks
+
+The [suite list](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/tests.mjs) declares 32 suites, 20 enabled by default. Local inspection of the pinned source archive found every declared suite entry path. The archive contained 1,118 files totaling 61,022,359 uncompressed bytes. For the root page plus the 20 enabled suite entry pages, a static HTML parser checked 194 `script`, asset `link`, and `img` references: none was external or missing. These numbers describe the checked archive, not a run result. The parser did not resolve dynamic JavaScript imports, CSS URLs, route requests, or user navigation.
+
+The [main page](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/index.html) loads local CSS and `resources/main.mjs`; the [runner](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/benchmark-runner.mjs) constructs `resources/${suite.url}`. The Perf Dashboard workload deserves special attention: its [static page](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/perf.webkit.org/public/v3/index.html) replaces its API method with `mockAPIs()` and fetches 13 specified local JSON paths. All 13 files exist in the pinned archive. The ordinary [dashboard remote API](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/perf.webkit.org/public/v3/remote.js) supports XHR, so verify the mock remains active in the actual packaged page.
+
+No `npm install` is needed to serve the already built workload assets. Upstream [development instructions](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/Development.md) use `http-server` for local development. Odin can serve the frozen file tree with its own loopback-only static server; do not rebuild application assets as part of a benchmark run. Use an HTTP origin rather than `file://`, since the suite uses modules, iframe paths, and fetches. The [upstream test harness](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/tests/run.mjs) is Selenium based and requires an installed browser and matching driver, per [Testing.md](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/Testing.md); it is not a prerequisite for serving the built pack.
+
+## Redistribution boundary
+
+The root [LICENSE](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/LICENSE) permits source and binary redistribution with or without changes if its copyright notice, conditions, and disclaimer are retained or reproduced as specified. This is not a blanket license for all included third-party work. The [TodoMVC subtree license](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/todomvc/license.md) states MIT unless otherwise specified and requires inclusion of its notice in copies or substantial portions. Built bundles also carry license files, including [React bundle notices](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/todomvc/architecture-examples/react/dist/app.bundle.js.LICENSE.txt), [Angular third-party notices](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/todomvc/architecture-examples/angular/dist/3rdpartylicenses.txt), and [React Stockcharts notices](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/react-stockcharts/build/static/js/2.8e539c84.chunk.js.LICENSE.txt).
+
+Pack the complete upstream notice files alongside their assets, preserve inline notices, and record a notice inventory with the pack manifest. A complete third-party license audit remains unresolved: the archive includes many generated bundles and assets, and finding a root license plus named notice files does not establish licensing for every individual asset. Review the final redistributed file set and notices before shipping. This is a licensing assessment from primary source text, not legal advice.
+
+## Browser mode and result identity
+
+Upstream [test instructions](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/instructions.html) call for a latest stable browser, clean profile, focused page, closed competing tabs, and no interaction during the run. The [page](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/index.html) warns when its visible viewport is below 850 × 650. The [parameters](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/params.mjs) separately default the suite iframe to 800 × 600 and expose iteration count, suite selection, and timing method. Record these exact conditions in Odin's run record.
+
+Use a headed, focused browser session for the comparable browser workload. Upstream provides no headless equivalence claim in the cited instructions or [Selenium runner](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/tests/run.mjs). Headless may be useful for a smoke test, but treat any headless measurement as a distinct software mode until equivalence is demonstrated. Do not silently mix browser versions, profiles, window/iframe sizes, suite selections, or headed/headless results in one calibrated measurement.
+
+## Manifest and offline acceptance proposal
+
+Create a deterministic, content-addressed pack manifest. Record: upstream repository URL and full commit; Speedometer 3.1 display version; every shipped relative path with byte length and SHA-256; a sorted inventory of license/notice paths; default suite names; and packaging schema version. Hash canonical serialized manifest bytes for the pack identifier. Verify each file hash before serving; reject missing, extra, or changed files. Keep the complete source snapshot or an auditable mapping from snapshot to shipped subset. This is an Odin design recommendation based on the pinned [runner paths](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/benchmark-runner.mjs), [suite list](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/resources/tests.mjs), and [license](https://github.com/WebKit/Speedometer/blob/1386415be8fef2f6b6bbdbe1828872471c5d802a/LICENSE); upstream does not prescribe this manifest.
+
+Before a benchmark run, validate offline behavior without collecting a score: serve the frozen tree on loopback, open the landing page and each default suite page in a disposable browser profile, disable outside network at the browser or sandbox boundary, log attempted requests, and check that all required assets load with no external request or console error. Include dynamic imports, CSS fonts/images, redirects, worker requests, and the Perf Dashboard JSON paths. Do not click Start Test during this gate. If the gate fails, report the missing/remote URL and mark the browser workload unavailable; do not substitute an online fetch. This acceptance procedure is proposed, not claimed as completed.
