A neighbour heard before the clock is set carries the firmware's unset-clock
default (1715770351, 15 May 2024). Subtracting that from an NTP-synced clock
published ages of ~806 days for neighbours that had just answered a live scope
query, and a backwards clock step reported 0, i.e. "heard just now".
- finishNeighborDiscover() reports the age as unknown ("heard_secs_ago": null)
when the stored stamp and the current clock come from different epochs, or
when the clock has stepped backwards
- handleNeighborDiscoverResponse() re-stamps heard_timestamp on a zero-hop scope
reply, in both the snapshot and the live table, so entries heal once per
discovery cycle instead of waiting for the neighbour's next advert
- publish ordering places usable ages ahead of unknown ones so a poisoned stamp
cannot displace fresh entries when the JSON buffer truncates
- document the null case, and the always-present total_neighbors /
queried_neighbors / truncated fields the payload sample omitted
- add UPSTREAM_BUGS.md, tracking the monotonic-uptime fix to propose upstream
plus the unclamped subtraction in the companion and CLI readouts
Containment only: upstream still stamps neighbours from the wall clock at
packet-reception time, which on a cold boot always precedes NTP.
