Address the three findings from the 2026-08-24 re-review of #6455, plus one finding from a follow-up adversarial review: - The switch trace now opens inside commitGuardedNavigation, only after the navigation guard accepts — a refused click can no longer leave an orphan trace that a later history navigation would settle with inflated time. The commit flow is extracted and dependency-injected; new unit tests pin guard ordering and the refusal→history-back case. - The perf-log 4 KiB cap now bounds bytes on disk: one byte is reserved for the newline writeln! appends. New boundary test measures the file. - The channel↔Projects benchmark gates readiness on a new data-projects-hydrating marker (driven by the surface's query fan via isLoading, so disabled queries never wedge it) instead of the shell header, verifies member inflation on both inflated channels, uses a prefixed ready-selector for general, and reports each switch direction as its own median so a one-leg regression cannot hide. - A settle wait that hits its 5s deadline while the render is still pending now records with settleWaitTruncated instead of posing as an honest settled paint — the >deadline tail is what the tracer exists to expose. Also removes the dead ChannelSwitchFetchTrace type. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Signed-off-by: Max Lampert <maxwell@squareup.com>
