The authenticated shell wraps every route and read one destination
predicate off the `@/lib/record-settings` barrel. That barrel also
re-exports the managed settings-patch schemas, so Zod, the module
registry and three validation modules rode into the eager client
bundle of every authenticated page for a function that inspects a URL
slug. The shell imports `record-settings/classification` now; the
barrel loses the re-export nobody else used.
Measured over all 585 client-rendered routes: none grew, 100 fell, by
4.7 KB gz at the median and 8.1 KB at the most. /insights had been
sitting on its 445 KB ceiling for three releases and went over it on
this branch's CI run; it measures 437 now, /measurements 435, / 450,
/insights/mood 450.
The whole-build sum moved the other way, 3451 to 3476, because the
aggregate counts each emitted chunk once: a graph that leaves the
chunk group every route shares gets counted again wherever it lands,
here inside the deferred settings chunks that use it. Bytes on disk
rose, bytes a reader downloads only fell. The aggregate cap moves to
3500 with the same 24 KB headroom the four earlier re-measurements
kept, and the reasoning sits next to the number.
The settling state's copy, the index-outcome plain-words line across
six locale catalogs and the reindex-count wiring take the whole-build
client sum to 3429 KB gzip, one kilobyte over the cap set at v1.37.4.
Every per-route ceiling stays met, so nothing a person downloads on a
given route grew beyond its ceiling; the aggregate cap moves to 3452
with the same margin as previous re-measurements.
Adding recoverable read-failure handling to thirteen surfaces and the MCP and
managed-record copy rewrites across six locales lifts the whole-build client
total to 3404 KB gz. Every per-route ceiling is still met; the aggregate cap
moves 3352 to 3428 with the same margin.
The /insights overview crept a kilobyte over its ceiling: the ECG
teaser imported its overview cap from the classification module, which
dragged that module's label map and helpers into the eager page, and
the Health Score card pulled the whole metric-provenance map for its
one citation. The cap now lives in a value-only module and the single
provenance entry is split out, so the overview imports the bare number
and citation it renders. Both routes are back under budget. The
aggregate ceiling rises to hold the six-locale copy the new encounter,
mood-context, mood-prognosis and practitioner surfaces added, which the
whole-build sum counts independently and no single route downloads.
CI died at the 4 GB default heap while checking types. The build was given its
own ceiling earlier this month so a local run, CI and the published image all
invoke it the same way; the type check was left on the default and has now grown
past it. Same treatment, same reason.
Also raises the aggregate bundle cap from 3260 to 3310 KB, and only that one.
Every per-route ceiling is untouched and every measured route sits within a
kilobyte of its previous value, so nothing a person downloads grew. The rise is
the new score-settings route, a mutually exclusive chunk that the whole-build sum
counts even though no single visit pays for it, plus its strings across six
locales. The reasoning is recorded in the budget file beside the number.
The measured first-load gap on / was never the server: FCP painted the
SSR shell at ~1.8 s but LCP landed at ~5.5 s (mobile-throttled) because
the tiles waited for JS download + hydrate + a CLIENT-side snapshot
fetch — while /api/dashboard/snapshot answers in ~8 ms server-side.
src/app/page.tsx is now a thin RSC wrapper: it runs the same cached
snapshot read the API route uses (extracted to
src/lib/dashboard/snapshot-read.ts, one shared SWR cell for both
readers) and hands the result to TanStack via HydrationBoundary +
dehydrate, so the first HTML carries real tile data and the mounted
cell starts warm (staleTime 60 s, refetchOnMount false — no double
fetch). Query keys come only from the central factory
(dashboardSnapshot(locale) + the dashboardWidgets seed the client cell
already performs); the payload is JSON-round-tripped so the hydrated
shape is byte-equal to the wire shape. Fail-soft: no session or any
builder error renders the page exactly as before. The 1,727-line client
page moves unchanged to src/app/page-client.tsx; no component-tree
rewrite.
Companion: the documented bundle tooling was dead on Turbopack
(ANALYZE=1 silent no-op, bundle-report read a webpack-only JSON), so
H2/H3-class regressions shipped invisibly. scripts/check-bundle-budget.mjs
derives per-route gzip totals from the Turbopack client-reference
manifests + rootMainFiles, prints the report (pnpm bundle-report), and
enforces bundle-budget.json (pnpm bundle-check): per-route caps,
total-client-JS cap, a recharts-duplication guard (fingerprint count
must stay 1), and a catalog guard (no message catalog referenced by any
route manifest). Wired into the existing e2e workflow after next build.
