Red commits: `dc7dcbe`, `76e3217` ([assertion failures](https://github.com/Kpa-clawbot/CoreScope/actions/runs/37059977385)). Fixes #2041; supplies #2085's backend contract. Records at most two route bits per retained advert. Node flood counts now use the same evidence, including mixed and transport-flood adverts. Analytics failures log/count errors while core observation, path and liveness writes continue. The unrelated recent-advert limit clamp is removed. Direct adverts (empty path) describes the observed remaining path across valid hash widths. Firmware can forward an advert down to an empty path; this cannot establish original send mode or RF distance. The `zero_hop` API spelling remains compatible. Successful post-upgrade evidence writes survive observation replacement and restart. Older overwritten frames and failed writes can leave gaps. The UI explains automatic background backfill. ## Measured validation Synthetic Windows workloads; timings are not production guarantees: - 300K retained adverts, one-hour window: median 64.35→39.84 ms; 13.98 MB→145 KB allocated. Seven-day allocations unchanged; five paired samples. - 1M transmissions/11M observations: backfill 5m43s. Simple 10 Hz writer: all 3,423 observations persisted; p99 28 ms, maximum 323 ms. - Simulated pre-backfill cursor: retained evidence ready 4m21s; full catch-up 6m41s, 122 cache invalidations. Normal completed-migration startup bulk-loads current evidence. Portable opt-in scale tests and window benchmarks are included. All 183 frontend suites, full server tests, targeted races, lint and real-API desktop/mobile checks passed. Full [Linux CI](https://github.com/Kpa-clawbot/CoreScope/actions/runs/37063210229) passed at `36def9c`; three independent reviews are clear. Local Windows testing hit the unchanged symlink-privilege test. No configuration changes. Preflight overrides: external script/OpenClaw profile unavailable; repository checks and Chromium used.
