The source-side "collided with existing call" warning fired on every dropped frame, flooding the log when streams contend for a slot (e.g. several peers on one master keying the same talkgroup). Gate it on a per-slot RX_COLLISION_SID so each contending stream is reported once, matching the once-per-stream behavior of the target-side contention log. Routing/emissions are unchanged; this is logging volume only. The dashboard's stale-stream reaper stays as-is for defense-in-depth (non-local dashboard, hblink failure, etc.).

Tests
Regression tests pinning the behavior of helpers extracted during the 2026 cleanup. They exist because a live OBP/HBP network with real DMR audio cannot be reproduced in a dev environment, so the routing helpers are validated in isolation instead.
test_acl.py—HBSYSTEM.dmrd_acl_check()(the shared master/peer ACL logic): PERMIT/DENY matching, per-timeslot scoping, and the once-per-stream drop logging.test_lc.py—gen_lcs()andembed_lc()frombridge.py: Link Control generation and the DMR payload LC rewrite used by all four group-routing paths.
Running
From the repo root, using the project virtualenv (which has twisted,
dmr_utils3, and bitarray):
venv/bin/python -m unittest discover -s tests -v
Pure stdlib unittest — no extra dependencies. They also run under pytest if
you have it installed (venv/bin/python -m pytest tests).
