Introduce downlink.py as the single authority for hotspot eligibility (OPTIONS,
slot busy, post-TX GROUP_HANGTIME). send_peer and BRDG fan-out share the same
gate; monitor events carry stream id from BRDG so new QSOs after hangtime
display without replaying calls blocked during the hangtime window.
Planned release: 2.2.0
* feat: persist peer dynamic TGs in MariaDB across reconnects
Add DATABASE config, async DynamicTgStore, and restore on RPTC so
SINGLE=0/1 dynamics survive hotspot disconnects and server restarts
without blocking the DMRD voice path.
* fix: ensure peer_dynamic_tgs table on server startup
Apply migration 004 idempotently at boot so the server does not depend
on adn-monitor db_bootstrap when peer_dynamic_tgs is missing.
* fix: import DynamicTgEntry for ruff F821 in subscription_table
* fix: log clear MariaDB startup failures to file and stderr
Validate DATABASE at config load and on connect; map common MySQL
errors to actionable messages so the server does not fail silently.
* fix: TG 4000 clears STATUS and bridge legs after dynamic reset
Clear RX slot state to stop RPTO re-seeding cleared sessions, run
in-band 4000 deactivation on inject-only paths, and mark downlink dirty.
* fix: complete TG 4000 reset for monitor and dynamic TG persistence
Emit INGRESS BRDG_EVENT so SINGLE=0 UA chips clear without stuck TX;
wipe all peer dynamic rows from memory and MariaDB on reset. Never store
TG 4000 as a UA session. Require DATABASE only for full peer-server configs.
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.
Require subscription_store in BridgeUseCases and route timer, OPTIONS,
static TG, and OBP mutations through store ops with export-only BRIDGES shim.
Fix dashboard YAML static TG fallback and sole-hotspot monitor remap for
dynamic UA when a bridge leg is active.
Sync subscription store after timer and in-band mutations, add optional
store authority with BRIDGES export shim, wire MeshCodecRegistry into
OBP udp_hbp paths, and extend harness parity tests.
Enforce strict SINGLE=1 RX exclusivity, always filter inject-only downlink by
each peer's own OPTIONS, and push self-service DB options only after PASS=.
Stop merged SYSTEM static TG lists from leaking across hotspots in topology.
