The gate summed every emitted chunk once and watched five pages. The sum counts a module once per chunk group it lands in, so it rose whenever a page got lighter by moving code into on-demand chunks, and it needed a raise in most releases while no reader downloaded more; and a heavy import into a page outside the five went unseen. scripts/check-bundle-budget.mjs now measures: - the first load of every page: rootMainFiles plus the page's client-reference chunks, each file counted once by content hash; - p50, p95 and max of those first loads across pages; - the distinct client code: every chunk evaluated in a node:vm sandbox with a stub TURBOPACK array, each module factory counted once by its module id (not its text: each chunk is minified on its own, so copies of one module differ in mangled names), catalogs excluded, gzipped once. The summed aggregate is still printed but no longer gated. The catalog, per-catalog and one-Recharts checks are unchanged. `--write-baselines` rewrites the per-page baselines, `--dir` measures another build directory, `--json` writes the report. bundle-budget.json is re-based from the v1.44.0 build (local arm64): 110 pages, first load p50 336, p95 437, max 451 KB gz; distinct client code 1904 KB gz in 1224 modules; summed aggregate 3875 KB for comparison. Every page has a baseline with the same 20 KB allowance; caps are p95 447, max 461 and distinct code 1930 KB. A page without a baseline fails until one is written in the same change. Proof: importing zod into the weight insights page measured /insights/weight at 427.8 KB gz, 88.8 KB over its 339 KB baseline, and the gate failed; the old gate passed the same build, because the page was not watched and the summed aggregate did not move (3875 KB). The import was removed again.
