The auto-discovery of known bots via the suffix only fed DM suppression,
which is moot since DMs are encrypted to one recipient. Channel
coordination now lands via patch 7's request token mechanism, which
doesn't need the suffix. Removes the marker, writeBotAdvertName,
isBotAdvertName, autoLearnKnownBotAdvert, and getAdvertNodeName; reverts
all four advert sites to use _prefs.node_name directly. Removes the
test_bot_advert_marker host test. Manual 'bot known add' from CLI still
works for explicit DM suppression.
Bots now prefix every response with a 4-hex request token derived from
the request fingerprint. Peers parsing the prefix can suppress their own
pending response for the same request, fixing duplicate replies on #bot
even for commands whose response text varies per bot (ack/test/hello/
status/roll/dice/path/trace/stats/time/lora/id/neighbors).
Patches 0001-0006 re-exported (cosmetic series-count bump 1/6 -> 1/7).
- All self-advert paths (CMD_SEND_SELF_ADVERT, CMD_EXPORT_CONTACT,
MyMesh::advert()) now use bot advert name with [MCBOT] suffix when
bot_prefs.enabled, via new getAdvertNodeName() helper
- Initial flood advert at 120s after boot instead of 24h, so other
nodes see [MCBOT] in the contact name shortly after the bot boots
- AUTO_ADD_OVERWRITE_OLDEST set by default on CMESH_BOT builds, so
bots don't silently stop accepting contacts when the table fills
Patches 0001-0005 re-exported (cosmetic series-count bump 1/5 -> 1/6).
Bundles in-progress utility commands (TIME, LORA, ID, NEIGHBORS), neighbor
tracking, received_at_timestamp / personalized acks, and per-hop response
delay coordination. Tunes the coordinator so multi-hop senders actually get
responses: hop step 5s→1.5s, hop bias capped at 8s, pending TTL 15s→45s.
Verified on Heltec V3 bench bot: responds to #bot at 2, 4, and 6 hops.
BOT_PREFS_VERSION bumped 2→3, so existing bots will reset bot prefs (channel
names, known bots) to defaults on first boot of this firmware.
