The SavedFilters incident shape — a page.goto fired while the previous
heavy RSC navigation was still in flight (net::ERR_ABORTED) — gets a
build-level guard: two gotos with no settle between them (await expect /
waitForURL / click / reload / login / catch) fail the suite. Measured
baseline on the current tree: 58 gotos across 17 specs, 0 unsettled
pairs — the six SOFT pairs from the miss audit all settle on awaited
assertions, so the guard starts clean without churning them.
TESTING.md records the convention the miss asked for: goto for cold
loads and URL contracts; in-shell navigation for continuity scenarios;
interactive-state waits before dynamic clicks; a dev-mode caveat for the
campaignLeaderships chip spec (deterministic dev failure at the
suggestion/commit step, prod green — ledgered).
