Allow mode: enforce in the report config, fail the command on over-budget and
unavailable routes, and make the markdown wording follow the configured mode.
Recalibrate the budgets against the webpack build (baseline x1.15, rounded up to
the next 10 KiB) now that the old Turbopack numbers no longer apply, so the
Docker image build gate blocks genuine bundle regressions instead of only
warning. Raise the Vitest coverage thresholds to the measured floor
(37.17/30.1/31.79/38.17 -> 36/29/30/37).
The performance report measured nothing. It only read `entryJSFiles` from
each route's client-reference manifest, a field Turbopack emits and webpack
does not. When the build moved to webpack (3d828a61) every route fell
through to the "unavailable" branch, and because the report is informational
and exits 0 on an unavailable metric, nothing failed and the budgets quietly
stopped being enforced.
Derive the envelope from clientModules[*].chunks when entryJSFiles is
absent, which is the same source Next's own static-routes-info uses for
webpack builds. Webpack interleaves numeric chunk ids with file names in
those arrays, so ids are skipped by shape while a malformed chunk path still
throws — otherwise a broken manifest would quietly under-report a route.
entryJSFiles still wins when present, since it is per-segment and therefore
the tighter envelope, and the per-chunk origin label is shared rather than
the absolute node_modules path webpack records, which would otherwise bloat
report.json.
Six tests cover the webpack layout: id filtering, deduplication of a chunk
reached by several client modules, the origin label, the malformed-path
rejection, the no-chunks-at-all case, and entryJSFiles taking precedence.
Re-measured on the current build, all six routes are inside their budgets
again. Note /admin/studio/furni now sits at ~98% of its gzip limit, so one
more dependency on that route will trip it; docs/performance-budgets.md
records the webpack baseline numbers and how to recalibrate.
Verified: 3385 tests, typecheck and biome clean, and the report now emits
measured rows instead of six unavailable ones.
