…ement) Kernel v0.16.29 requires an X-Cogos-Grant header on all POST/PUT/PATCH/ DELETE routes. Adds a per-process grant helper to the three cogos-harness hooks that POST to the kernel (session registration and session-end): user-scope-session-start.py, user-scope-session-end.py, seat-identity-heal.py. The helper reads ~/.cog/vault/node-root-grant, falls back to the loopback grants/current endpoint, and caches the result in-process. Grant-acquisition failure is fail-open -- the hook proceeds without the header exactly as before, so a broken vault degrades to the pre-v0.16.29 401 rather than blocking the hook. compaction-handoff.py and kernel-vitals-probe.py are unaffected: the former never calls the kernel, the latter is GET-only.
