Administrator 9cc8fee02c docs(todo,lessons): long-run lag root cause was the recent-panel append-gate cliff (measured 80ms->7ms) ... Records the verified root cause + the dismissed-with-evidence findings: - _sessionFileKeys "separator mismatch" = FALSE POSITIVE (real U+0001 chars, verifier Read rendered them invisibly) - queueJobs O(N) per-render scan = real but Blink-measured <0.1ms at 3000 jobs -> skipped - standing 2000-row relayout = median 0.4ms -> no virtualization needed - doodstream sync _debugLog = constant freeze, deferred to a separate change Lesson: measure magnitudes at the real artifact before fixing a "scales-with-X" cause; profile in real Blink (Playwright) not jsdom; verify multi-agent findings against primary evidence (char-code dump caught the control-char false positive).
