feat(status): reorder by data flow, sharpen reception signals#93
Merged
Conversation
Status output now follows the actual data path. Adds a receiver-activity byte sample, narrows the uplink check to ADS-B ports, raises server-reception tiers to match the 5-min sync, folds MLAT privacy in, and bumps --json to v2.
ADS-B uplink now parses the peer column only so a local listener on :30004/:64004 can't false-positive; netstat fallback enforces ESTABLISHED. Receiver activity skips on warn (not just fail) so malformed INPUT doesn't show a misleading second 'no data' line. Unknown mlat_private values surface as their own warn instead of being silently swallowed by the MLAT-line privacy fold.
CI runners ship /usr/bin/ss, so rm'ing the STUB_DIR/ss stub left command -v ss finding the system binary and the ss branch ran instead of the netstat fallback. Override command() in the test scope so BATS run inherits a definition that returns 1 for ss only.
The (vN) suffix is internal bookkeeping; operators have no actionable use for it and v1 just looks confusing on a freshly-registered feeder. Kept in --json (.claim.version) and the local mirror file for tooling.

The status output now follows the actual data path so a reader can walk it top-to-bottom: receiver input → receiver activity → feed service → ADS-B uplink → identity → server reception → MLAT → diagnostics push.

Receiver activityline samples the receiver socket for ~2 seconds and reports whether bytes are actually arriving, so an unplugged antenna or silent decoder surfaces as a warning instead of hiding behind a port that still listens.Airplanes.live linkis renamed toADS-B uplinkand narrowed to ports 30004/64004 — the failover target was missing, and the old check accepted :31090, so a MLAT-only connection used to mask an ADS-B-down state.Website feedbecomesServer receptionwith tier thresholds raised to match the 5-minute server-side sync (ok≤ 8 min,warn≤ 20 min,failbeyond) and a first-connect hint on the not-seen-yet case.
