Port the observer firmware's neighbours feature into the bot's packet capture
service, by way of meshcore-packet-capture (upstream PRs #42/#43). On a long
interval the bot asks which repeaters it hears directly and records each
confirmed link with its measured SNR.
This is the strongest link evidence the bot collects: a first-party RF
measurement between two full 32-byte public keys. Path inference works from
1-3 byte prefixes with no keys, and complete_contact_tracking.hop_count
over-claims zero-hop (800 claimed vs 68 corroborated on the live database).
modules/neighbors_discovery.py keeps upstream's public names so its fixes and
tests stay portable. Two deliberate divergences:
- No command_lock plumbing. _SerializedCommands in modules/core.py already
serialises and paces every radio command, strictly more than upstream's
reentrant lock did.
- neighbors_collect_scopes defaults off. Upstream's zero-hop scope probe
relies on a neighbour not being a known contact; this bot tracks contacts,
and for a repeater with no stored path the library reaches zero-hop by
calling change_contact_path() then reset_path() -- mutating the device's
contact table per neighbour. Scope requests also hold the radio lock for
their whole round trip (~25s), stalling bot replies. The default cycle is
one command plus a passive listen window, during which the bot stays
responsive.
Evidence lands in neighbor_links and neighbor_observations (migration 22)
rather than mesh_connections, which cannot persist provenance. The viewer
exposes it as evidence=neighbors on /api/mesh/edges and a Neighbours Only
mode on the mesh page, with populated public keys and real SNR; confirmed
neighbours also relabel edges in the combined view and count as
provenance-trusted when framing the initial map.
neighbors_enabled is the single switch. Every enabled broker publishes once
it is on (mqttN_neighbors defaults true; set false to hold one back). The
topic derives from each broker's packets topic with the last segment swapped,
so a templated broker gets meshcore/{IATA}/{PUBLIC_KEY}/neighbors -- the
topic the firmware uses -- instead of an unrelated flat one. A derived
location-routed topic is skipped with a warning when no iata is set, rather
than publishing into meshcore/XYZ/... on a shared namespace. Snapshots are
non-retained: heard_secs_ago is relative to publish time, so a retained copy
would read as current days later.
Also adds a DM-gated `neighbors` command (the 12h interval floor makes
waiting for the scheduler impractical), which acks immediately and reports in
a second message once the window closes.
