* perf(bundle): drop the BAS chart and the Node crypto polyfill from the shared client baseline
Two chunks rode along in the first-load JS of almost every dashboard route:
the full BAS 2026 chart (315 KB uncompressed, in 81 route manifests) and
the browser polyfill for Node's crypto/vm/Buffer (327 KB, in 26 routes
incl. login and register). Neither was needed on first paint; both got
there through static imports of helpers that happen to live next to code
that needs the data or the builtin.
Node polyfill (4 pure splits, behaviour unchanged, re-exported from the
original modules for server callers):
- lib/auth/bankid-flags.ts: isBankIdEnabled (login, register, security
settings imported it from bankid.ts, which imports crypto).
- lib/import/bank-file/formats.ts: the format registry + detection (the
import history imported getFormat from parser.ts, which hashes).
- lib/salary/personnummer-format.ts: parsing/validation/formatting (the
employee forms reached the encrypting personnummer.ts via tax-column).
- lib/auth/api-key-scopes.ts: scope catalogue, groups, tool map, helpers
(the API key panel imported STAGING_SCOPES from the key generator).
BAS chart:
- lib/bookkeeping/bas-lazy.ts + use-bas-reference.ts: the chart becomes a
dynamic import, fetched once per session after first paint; components
that show BAS names/descriptions call useBasReference() and re-render
when it lands. Until then (and on the server) only the hardcoded
account-descriptions answer, so SSR and hydration agree.
- lib/bookkeeping/bas-labels.ts: class/group labels out of bas-reference.ts
(account-descriptions needed a label and paid for the whole chart).
- lib/bookkeeping/bas-account-numbers.ts (generated, ~11 KB) +
scripts/generate-bas-account-numbers.ts (--check) + parity test:
isStandardBASAccountNumber for AddAccountDialog/ChartOfAccountsManager.
- lib/bookkeeping/account-classifier-{heuristic,client}.ts: the BAS-aligned
heuristic shared by the server classifier and a client variant that uses
the lazy chart.
- lib/bookkeeping/invoice-accounts.ts: INVOICE_FX_RATE_MISSING,
InvoiceFxRateMissingError, getRevenueAccount, getOutputVatAccount out of
invoice-entries.ts, whose engine import pulled account-backfill and the
chart into SendInvoiceDialog/PaymentBookingDialog.
- CorrectOpeningBalanceDialog re-seeds names when the chart lands;
OpeningBalanceRowEditor builds its Fuse indexes lazily; the
ChartOfAccountsManager BAS-katalog tab awaits the chunk.
Tooling:
- scripts/perf/client-import-closure.mjs: static import closure of every
'use client' module with the shortest chain to a target (file or bare
specifier); found every path above without a build.
- scripts/checks/client-node-builtin.mjs wired into check:guards: a client
module reaching a Node builtin is a hard failure (0 today).
Left as is: invoices/[id], its credit page and SendInvoiceDialog still
reach the chart through lib/invoices/issue-credit-note -> invoice-entries
-> engine -> account-backfill; splitting the engine is out of scope here.

* fix(perf): unambiguous import-edge regex in the closure walker (CodeQL js/redos)
One quantifier per span: a greedy [^'"]* up to the specifier quote, which it
cannot cross, so a run of whitespace has a single parse. Same edges as
before (multi-line named imports, re-exports, side-effect imports; type-only
imports still skipped).

The proxy in front of every page, RSC, prefetch and /api request makes
several sequential network calls (getUser, session state, the
resolve_active_company RPC, MFA factor lookups) and nothing measured them,
while the route wrapper has logged authMs/companyMs/handlerMs per API call
for months. This is the first PR of the responsiveness plan (customer
report: "it takes time before all fields load when clicking around"): the
baseline every later change is measured against.
- lib/supabase/proxy-timing.ts: pure helpers (request classification from
the app-router headers, route template that collapses ids and tokens,
Server-Timing formatting, a timed() accumulator).
- lib/supabase/middleware.ts: updateSession wraps updateSessionInner, times
each phase, sets Server-Timing on page/RSC/prefetch responses and
X-Proxy-Timing on /api responses (withRouteContext owns Server-Timing
there), and emits one "proxy completed" log line per request.
- scripts/perf/log-percentiles.ts: p50/p90/p99 per group over
`vercel logs --json` output, for both "op completed" and
"proxy completed"; scripts/perf/README.md documents the protocol and
targets.
