Not for merging. These are the apps and scripts behind the numbers in #3244–#3247, kept here for inspection. Details are in apps/bundle-size-lab/README.md.

• Apps: standalone Vite 8 apps made from the four docs examples with the most 'use gpu' functions (monocular-light-injection, selfie-segmentation, os-awards, jelly-slider), each built into one minified chunk. Env vars toggle unstable_stripJsImpl, unstable_obfuscate, unstable_minify and auto-naming.
• measure.ts: raw/gzip/brotli size of every build, bytes per part of the metadata, and bytes per source (from sourcemaps). results-{main,pr2,pr3,pr4}.json come from running it with the repo at main and at each PR of the stack.
• formats.ts: re-encodes the metadata in the built bundles in candidate formats and measures the resulting bundles, plus ablations (no AST, no externals, no metadata).
• bench.ts + decoders.ts: cold-start benchmark of the formats. One fresh Node process per run compiles and runs each app's metadata, then reads all of it. Every format is first checked to decode to the same AST.
• evaluate.ts: time to import whole bundles in fresh Node processes, with two builds interleaved.
• serve.ts: serves the builds and records every shader module's code. That's how the generated WGSL was compared between builds in Chromium.
• examples/tests/revive-check: checks unstable_stripJsImpl by calling functions on the CPU.
