CPU profile evidence (CDP Profiler + Tracing, additive
neode-ui/e2e/perf/profile-revisit.spec.ts, frozen harness untouched)
shows 86-99% of every revisit window spent in (idle)/(program) with
under 10% genuine app JS self-time on every surface — ruling out
expensive computed re-evaluation, watcher cascades, and whole-subtree
re-renders as the dominant cost, per the plan's own explicit list of
hypotheses to check before accepting one.
A follow-up source-level lifecycle audit (grep every setInterval call
site for a missing onActivated/onDeactivated pair, extending 02-04's
own audit convention past the top-level view files it originally
checked) found three child components/composables inside the
KeepAlive'd Fleet/Server/Web5 subtrees that arm a poll in onMounted
and only ever clear it in onUnmounted — harmless before phase 2
(the view was destroyed on tab-away) and now a permanent, session-long
background-RPC cost once KeepAlive keeps the parent instance alive:
useFleetData.ts (60s), FipsNetworkCard.vue (15s, Server), and
Web5Monitoring.vue (30s, Web5 — redundant with Home.vue's own,
correctly-gated 10s poll of the same store).
This directly explains the idle-dominated CPU signature (background
network/scheduling contention, not compute) and why 02-10's 5-run
remeasure regressed further than the 3-run baseline/after runs even
as disk pressure eased: a longer session accumulates more of these
always-on pollers, degrading every subsequent navigation.

Task 1: built keepalive-remount-probe.spec.ts, a committed, re-runnable
Playwright spec covering every KEEP_ALIVE_PATHS tab with three added
instruments (instance-uid, session-wide console/pageerror capture, DOM
population/pathname logging per hop) beyond 02-08's ad-hoc probe.
Eliminated suspects 2 (runtime error), 3 (LRU eviction), 4 (route.path
mismatch) and 5 (include-name matching) by direct measurement. Confirmed
suspect 1 with positive proof: an authoritative document.elementFromPoint()
hit-test signal contradicted the naive selector-match method's "remounted"
verdict for both Server and Web5 across independent runs, and a companion
diagnostic found the original stamped root still connected+visible under
a different (unpicked) match. Root cause: Server, Web5 and Fleet share the
fully generic .view-container [data-controller-container] selector every
KeepAlive-cached main tab's root carries via fallthrough, which cannot
disambiguate "the foreground tab" from "another cached tab still connected
to the document" once more than one tab has been visited — the normal,
intended KeepAlive state. Settings (the away tab every round trip uses)
independently renders matching content too (AccountInfoSection/
KioskDisplaySection), compounding the ambiguity.
Server.vue and Web5.vue's instances survive tab round-trips exactly like
every other registered tab — no defect in DashboardRouterView.vue,
dashboardViewWrappers.ts, keepAliveRoutes.ts or Server.vue's KeepAlive
wiring. 02-FINDINGS.md records the full method, eliminated suspects and
verdict per D-10 (this commit lands before any src change, per gate).

- 02-PERF-BASELINE.json: on-device baseline recorded against archi-dev-box
(real hardware, D-11's verification target). 13/15 surfaces measured
cleanly across 3 runs each; Mesh and Chat are recorded as unmeasured with
their reasons (Mesh: no connected mesh device on this node within the
wait window; Chat: AIUI's own loading overlay outlives the close-button
click budget) rather than silently marked already-fast, per plan rule.
- measure.ts: goHome() now falls back to a hard `page.goto('/dashboard')`
when the Chat surface's own close button is unreachable (blocked behind
AIUI's connecting overlay on real hardware) — without this, every
surface after Chat inherited a permanently hidden sidebar
(`v-show="!chatFullscreen"`) and cascaded to unmeasured. This recovery
path is exempted from the "no page.goto between surfaces" rule because
it exists only to break out of a stuck state, not to measure one.
- surface-perf.spec.ts: currentCommit() now shells out with `process.cwd()`
instead of `__dirname`, which is unavailable under this package's
`"type": "module"` runtime and was silently recording every run header's
`commit` field as 'unknown'.
No file under neode-ui/src/ was modified by this task (git diff --name-only
HEAD -- neode-ui/src is empty).

- surfaces.ts: SURFACES table covering all D-09 surfaces (home/wallet,
apps, marketplace, discover, cloud, mesh, server, web5, fleet, chat) plus
four secondary screens (AppDetails, MarketplaceAppDetails, CloudFolder,
OpenWrtGateway) and the located wallet-send modal. Navigation is via real
RouterLink/button clicks (never page.goto) so revisit measures actual
Vue Router client-side transitions.
- measure.ts: measureSurface() records first-visit vs revisit timing, an
RPC method+timing trace (no bodies), a dataset-stamp remount probe, and
derives maxConcurrentRpc/rpcWallClockMs via sweep-line so serial
waterfalls are distinguishable from parallel fan-outs. Includes a
dismiss-and-retry click guard for stray modals (Companion app intro) that
would otherwise cascade failures across surfaces.
- surface-perf.spec.ts: logs in via the existing app-launch flow, walks
every SURFACES row, writes results + a run header to ARCHY_PERF_OUT.
Verified end-to-end against the local mock-backend + vite dev server
(14/15 surfaces measured cleanly across 3 runs each; the 15th, Mesh, times
out only because the mock backend never reports a connected mesh device —
expected to resolve against a real node in Task 2).
