Dedupe the INFO line when a peer keys into a busy TG during an active QSO,
bind RX_STREAM_ID on silent activation to avoid per-frame re-entry, and
clear the dedupe marker on suppressed-stream VTERM.
Enforce one active group QSO per peer/slot (SINGLE=0 and SINGLE=1) at the
downlink layer instead of treating the shared MASTER STATUS[slot] as a single
RF slot. Concurrent streams from different hotspots to different TGs are now
legitimate on ingress; contention is decided per-peer.
- Ingress: hbp_ingress_new_stream_collision honours per_peer=True so a second
hotspot is not silenced by the first; hbp_master_ingress_repeat_allowed
applies the same multi-hotspot rule and always passes VTERMs so listener
sessions close and mid-call join works.
- Silent activation: TX onto a TG with an active QSO activates the TG
dynamically, suppresses the uplink, and delivers the in-progress QSO
downlink. Only a TG in GROUP_HANGTIME (no live stream) is rejected.
- Downlink: peer_voice_slots tracks one listen TG per peer/slot with
GROUP_HANGTIME and bridge-hold semantics; stale sessions expire after
STREAM_TO; duplex slots stay independent.
- Non-regression tests for slot contention, silent activation, stale session
expiry, and duplex independence.
Normalize all Python sources to the standard ADN copyright block with
complete GPLv3 notice. Add legacy attribution on routing and dmr_utils
ports; drop SemVer wording from changelog and fix an unused test import.
Replace internal bridge terminology with routing (RoutingUseCases, AclRouter,
routing_table export). SubscriptionStore remains runtime authority with O(1)
indexes for router and downlink filters. Fix STATIC TG parity on OPTIONS/RPTO,
parrot in-band edge cases, and remove per-packet routing_table export from the
hot path that caused high CPU under multi-hotspot OBP load.
