 ### Blockers/Concerns
 
+- **PHASE 8 ESCALATION (open, 2026-10-25):** the CPU verdict measured FAIL post-ALT (25-route p95 152.788 ms / extended 185.692 ms vs the 8 ms budget; the L=32 probe worse) — the c3 class remains. The theoretical wall: no two-sided-Lipschitz landmark extension exists on a graph with sentinel fringes; sound+fast needs direction-split potentials with a re-proven meet rule (search-skeleton work). Options: direction-split potentials (new phase) / CH (Phase-6 deferral) / Workers Paid reversal ($0 law) / keep c3 (current shipped posture). Records: docs/BUDGETS.md §c3, docs/KNOWN-LIMITATIONS.md, 08-05-SUMMARY.md.
 - ~~PHASE 4 device-gate legs UNVERIFIED~~ RESOLVED 2026-10-24: legs 1–4+6 PASS on real hardware; leg 5 user-accepted (BotFather Main Mini App configured; unknown-id surface covered by automated gates). Known-open cosmetic: /cari absent from the client command menu (Telegram non-default setMyCommands defect; command works when typed; register script re-arms all scopes for retry).
 - Design-source conflict (root `DESIGN.md` typography vs `telemetry_rams/DESIGN.md` + mockups) — Phase 1 resolves; mockup markup is layout reference only, design doc tokens are binding (scrub rounded/blur utilities)
 - ~~VPS provisioning starts in Phase 4 (Photon bake-off)~~ SUPERSEDED by Phase 4 D-03: search is an in-Worker curated gazetteer ($0); VPS provisioning (Valhalla + Photon) defers to Phase 5; Photon is a documented SearchSource backend #3 (free-first mandate: one VPS, Oracle Cloud Always Free candidate)
