Deployed the poller fix to archi-dev-box and re-ran the frozen harness
(02-PERF-FINAL.json, 5 runs/surface). Web5 fixed (275ms, below both
its 566ms pre-phase-2 baseline and the 300ms pass bar). Server's
regression closed (574ms, below 738ms baseline) though not yet under
300ms. Fleet substantially improved (790ms, down from a 2631ms
regression). AppDetails restored to at/near its own baseline.
Investigated the two open items the coordinator raised:
- OpenWrtGateway: this run's 5/5 samples failed with a Chromium
"Target crashed" error cascading from an unrelated surface earlier
in the same harness run — recorded as not-measurable, not written
in as data. Separately confirmed via source (OpenWrtGateway.vue's
h1 renders unconditionally, and a "No router configured" RPC error
deterministically shows a real Connect-to-Router form) that the
prior baseline/after/remeasure numbers were measuring a genuine,
substantive disconnected-state UI render, not an empty/error page —
so the "six confirmed regressions" count is not retracted, but the
numbers are flagged as reflecting one specific code branch.
- Discover (1389ms, worst remaining, least improved): profiled
directly and found a SECOND, distinct, phase-2-class cause —
showStagger/card-stagger entrance-animation classes are baked into
the DOM at first mount and never programmatically removed (the flag
is a correctly-scoped once-per-session const, but nothing ever
re-renders to strip the class), so every KeepAlive detach/reattach
cycle restarts the CSS animation on reactivation, replaying the full
entrance cascade on every revisit. Confirmed via a diagnostic
showing DOM card count doubling transiently on every revisit and an
extended animationstart/animationend event log. Not fixed this pass
— the safe fix's blast radius spans 5+ files outside this plan's
scope (Apps.vue, Marketplace.vue, Home.vue, several Web5 sub-cards)
and needs its own real-device verification budget, matching the
precedent 02-02's original KeepAlive rollout needed for this exact
class of change. Named and evidenced, recommended as a dedicated
follow-up rather than expanded into this plan under time pressure.
REQUIREMENTS.md's PERF-02/PERF-03 rows updated to the final state.
