box fleet status / approvals check misreported every node as STOPPED / CDP-unreachable from sandboxed shells (own PID+net namespaces: pgrep blind, no route to 10.201.x.x, no sudo). Fleet was healthy throughout. - bin/host_evidence.py (new): host watchdog evidence fallback. Recent timer runs (journal -o json, exact UNIT match) with no newer failure line in cdp-relay-watchdog.log / chromebox-watchdog.log (both silent-when-healthy) prove a node is up. def/dev have no watchdog coverage: browser verdict via chromebox-<node>.log freshness (alive-only), CDP verdict unknown. - super-cli.py: effective status/source/evidence per node. Host evidence decides ONLY the fully-blind pattern (both local probes negative); live local signals always win. New UNKNOWN badge, [*] footnote; approvals UNREACHABLE splits into BLIND / OFFLINE(host agrees) / unreachable-evidence-inconclusive, with honest footer. proc_alive/cdp_ok keep local-probe meaning; status/source/evidence are new JSON fields. - approvals.py: host_cdp_ok flag on the unreachable path. - agent-health.sh: restart circuit breaker. 3 consecutive futile restarts (restart leaves agent still failing) opens the circuit: no more kills for 1800s, ALERT to log+journal, half-open probe after cooldown, reset on any success. Stops the def murder loop (57 restarts / 155 API FAILs for an account-layer failure). - tests/test_fleet_status.py (25), tests/test_agent_health.py (6). - CHROMEBOX-RUNBOOK.md: blind-shell status + futile-restart sections. Tests: 98/98 focused green (agent_health + fleet_status + completion + tool_calls). Live-verified: 4 ACTIVE [*] + 2 UNKNOWN.
