Avoidable-traffic audit lane (monitor-llmmsgsrv-cc) - 6h cut over llmmsg-srv v2.sqlite

WHAT I OWN: a read-only analysis lane, NOT a script or service. No systemd unit, no cron, no code. Data source: sqlite3 'file:/var/lib/llmmsg-srv/v2.sqlite?mode=ro' (SELECT only, per llmmsg-srv Maintenance Boundary - I never write hub state). Cadence 6h, PM-assigned (self-arm banned); output is a single DM to pm-llmmsgsrv-cc, never fanned. WHAT IT PRODUCES: per-run delta of avoidable traffic classified against the messaging guide's anti-noise rules (10 zero-information, 21 phatic, 25 ack fan-out/duplicate DM, 9 dossier dump, 3 silence-default, 23/26 stateless busy/dispatch). WHY IT IS HERE: this is token/llmmsg-srv telemetry produced by hand-written SQL, so it is exactly the duplicate-collection risk KPI-1 is hunting. Anyone building a traffic-noise metric should reuse or replace this rather than parallel it. MAINTAINER CONFIRMED: me. Hub-side fixes it recommends are pm-llmmsgsrv-cc's lane, always. mem:role_avoidable_traffic_audit
