THE ONE QUERY (#1157/#1160): the latest capture-health projection for ONE device — one `device_health` row, no scan, no on-device access needed. Answers "is the TLS-intercept engine armed, and if not, WHY": engine_state ('armed'|'inert') + engine_reason (e.g. no_ca_key) + state_established_at (when that state was first established, so a stale fact is visibly stale), the CA triple (ca_loaded / ca_key_present / ca_trusted — 'trusted CA, missing key' means refetch the cert BUNDLE; 'CA not trusted' means reinstall the profile: opposite fixes today's signals cannot distinguish), ssl_domain_count + ssl_domain_hash (compare against the server's expected effective-settings hash: mismatch = config-delivery fault, match + inert = engine fault), config_hash/config_fetched_at, the decrypt counters (flows_total / flows_decrypted / flows_reasons {reason: count} over no_engine|no_sni|out_of_scope|leaf_mint_failed|ca_untrusted|pinned|upstream_failed), events_dropped + last_seq/seq_gaps (the telemetry stream's own honesty detectors), tunnel_state, app_build + ios_version + boot_id, and last_error. The row is trigger-written from device_events (the DEVICE's own claims about itself — diagnostic, never authorization). iOS-ONLY BY TRIGGER (#1208): device_events is a MULTI-PRODUCER stream (the PAC/proxy server writes to it too), but this projection admits ONLY legacy/no-producer and detail.producer='ios' rows — a proxy/PAC event can never refresh last_event_at/updated_at or overwrite last_error, so this row is never 'recently healthy' on another process's evidence, and every unknown future producer fails closed the same way. For the proxy's own stream use list_device_events with producer:'proxy-server'. A device with NO row returns found:false + a note (it has never emitted telemetry — needs an iOS build with the #1160 emitter); that is a NORMAL complete answer, and absence of telemetry is never evidence of health. Owner-scoped: without devices:view you may still read YOUR OWN device by uuid/name.
