sjg 19ab3b3931 [feat](trx-rs): remove MARINE mode (superseded by virtual channels)
MARINE was a composite mode that ran both AIS and VDES decoders
simultaneously. It is now fully replaced by allocating two virtual
channels — one tuned to the AIS frequencies and one to VDES — each
decoded independently.

- trx-core/state: remove RigMode::MARINE variant
- trx-protocol/codec: remove MARINE parse/serialize
- trx-backend-ft817: remove MARINE from unsupported-mode guard
- trx-backend-ft450d: remove MARINE from FM CAT code mapping
- trx-backend-soapysdr: remove MARINE from bandwidth table, supported
  modes list, AIS channel activity check, parse_rig_mode, vchan_impl
  bandwidth table, demod selection, dsp/channel bandwidth / sample-rate
  / IQ-tap guards
- trx-server/audio: remove MARINE from AIS and VDES decoder activation
- trx-server/rig_task: remove MARINE from audio-streaming mode list
- trx-server/main: remove MARINE from bandwidth table, mode parser,
  VDES channel subscription match
- app.js: remove isMarineMode(), MARINE entry in MODE_BW_SPECS, MARINE
  bandwidth specs block in visibleBandwidthSpecs(), MARINE from
  decoder status mode lists, MARINE BW-edge drag guard

sjg 60267d450b [feat](trx-rs): persistent multi-channel virtual channels with OOB eviction
Allow users to allocate multiple virtual channels independently of
browser tab count. Channels survive SDR center-frequency retuning as
long as they stay within the capture bandwidth; channels that fall
outside the SDR span are automatically destroyed.

Changes:
- trx-core: add AUDIO_MSG_VCHAN_DESTROYED (0x12) wire constant;
  add default subscribe_destroyed() to VirtualChannelManager trait
- trx-backend-soapysdr: update_center_hz() detects OOB channels,
  removes them, fires destroyed_tx broadcast; add destroyed_sender()
  and subscribe_destroyed() override
- trx-server/audio: recv_destroyed() helper avoids select! busy-loop
  for non-SDR backends; send AUDIO_MSG_VCHAN_DESTROYED to client when
  a channel is evicted server-side
- trx-client/audio_client: persist active_subs across TCP reconnects,
  re-subscribe on reconnect; handle AUDIO_MSG_VCHAN_DESTROYED by
  pruning vchan_audio map and forwarding UUID via vchan_destroyed_tx
- trx-frontend/lib: add vchan_destroyed broadcast field to
  FrontendRuntimeContext
- trx-client/main: wire vchan_destroyed_tx into audio client and
  frontend runtime context
- trx-frontend-http/vchan: remove per-session one-channel limit in
  allocate(); replace auto-evict in release_session_on_rig() with
  subscriber-count-only update; add remove_by_uuid() for server-
  triggered OOB destruction (skips redundant VChanAudioCmd::Remove)
- trx-frontend-http/server: spawn background task that forwards
  vchan_destroyed broadcast to ClientChannelManager.remove_by_uuid()

sjg 6131d7a1d6 [feat](trx-rs): per-virtual-channel audio streaming
Add end-to-end audio routing for virtual DSP channels:

Server (trx-server):
- New wire protocol: AUDIO_MSG_RX_FRAME_CH (0x0b), VCHAN_ALLOCATED (0x0c),
  VCHAN_SUB (0x0d), VCHAN_UNSUB (0x0e), VCHAN_FREQ (0x0f), VCHAN_MODE (0x10),
  VCHAN_REMOVE (0x11) frame types in trx-core audio.rs
- Add frame helpers: write_vchan_uuid_msg, write_vchan_audio_frame,
  parse_vchan_audio_frame, parse_vchan_uuid_msg
- Add ensure_channel_pcm() to VirtualChannelManager trait; implement in
  SdrVirtualChannelManager with create-or-subscribe semantics using client UUID
- Extend audio.rs handle_audio_client: VChanCmd dispatcher, per-channel Opus
  encoder tasks, VCHAN_SUB/UNSUB/FREQ/MODE/REMOVE reader loop handlers
- Thread vchan_manager through run_audio_listener / spawn_rig_audio_stack

Client (trx-client):
- Add VChanAudioCmd enum to trx-frontend; add vchan_audio and vchan_audio_cmd
  fields to FrontendRuntimeContext
- Extend audio_client: demux AUDIO_MSG_RX_FRAME_CH to per-channel broadcasters,
  handle VCHAN_ALLOCATED; forward VChanAudioCmd over TCP write loop
- Wire vchan_cmd_tx/rx channel in main.rs; pass vchan_audio map to audio_client
- ClientChannelManager.set_audio_cmd() / send_audio_cmd(): dispatch
  Subscribe/Remove/SetFreq/SetMode on allocate/delete/freq/mode operations
- Wire audio_cmd sender in server.rs serve() after creating vchan_mgr

HTTP frontend:
- /audio?channel_id=<uuid>: route WebSocket to per-channel Opus broadcaster
- vchan.js: vchanReconnectAudio() stops/restarts RX audio on channel switch;
  _audioChannelOverride in app.js selects primary vs virtual WS endpoint
- app.js: _audioChannelOverride variable; startRxAudio appends channel param

sjg dda5ec17bb [feat](trx-backend): VirtualChannelManager trait + SdrVirtualChannelManager impl
Add VirtualChannelManager trait in trx-core::vchan with types VChannelInfo,
VChanError, and SharedVChanManager alias. Re-export from trx-backend::vchan.

Implement SdrVirtualChannelManager in trx-backend-soapysdr:
- Wraps Arc<SdrPipeline> + shared AtomicI64 center_hz
- add_channel / remove_channel / set_channel_freq / set_channel_mode
- Slot-stability: on remove, shifts pipeline_slot for surviving channels
- update_center_hz: recomputes IF offsets for all virtual channels on retune
- update_primary_meta: keeps channel-0 freq/mode in sync for API consumers

Wire into SoapySdrRig (holds Arc<SdrVirtualChannelManager>, exposes
channel_manager()), SdrPipeline (shared_center_hz AtomicI64), and RigHandle
(vchan_manager: Option<SharedVChanManager>). main.rs extracts the manager
before boxing the SDR rig and stores it in the handle.

Add max_virtual_channels to SdrConfig (default 4, TOML-configurable).
Add 5 unit tests: add, remove, permanent guard, cap, out-of-bandwidth.

sjg 05169912b1 [feat](trx-backend-soapysdr): dynamic virtual channel DSP slots
Replace the fixed channel_dsps Vec (thread-owned) with an
Arc<RwLock<Vec<...>>> shared between the IQ read thread and the async
side, enabling live add/remove of virtual DSP channels.

Cache audio construction params in SdrPipeline so add_virtual_channel()
can build ChannelDsp instances without being re-passed them. Add:
  - SdrPipeline::add_virtual_channel() / remove_virtual_channel()
  - SoapySdrRig::virtual_channel_add/remove/set_freq/set_mode()
  - SoapySdrRig::center_hz() / half_span_hz() accessors

The IQ read loop holds a brief read lock (~2 ms per block) while
processing all channels; write lock for add/remove waits at most one
block. All 27 existing tests continue to pass.

sjg 409b173f62 [feat](trx-server): gzip-compress history replay blob
Add flate2 dependency and a new AUDIO_MSG_HISTORY_COMPRESSED (0x0a)
wire type. The server gzip-compresses the full history blob before
sending; JSON history compresses ~10-20x so both transfer size and
client wait time drop significantly. The client decompresses and
dispatches sub-messages from the embedded framed stream. MAX_PAYLOAD_SIZE
is kept at 1 MB for normal messages; a separate 16 MB limit is applied
only to the compressed history type.

sjg 53199642ea [fix](trx-server): fix VDES channel routing and IQ sample rate
Subscribe to the first sdr.channels[] entry configured as VDES or
MARINE instead of always using channel 0.  The ChannelDsp IQ tap only
emits samples when its own mode is VDES/MARINE, so the two must agree.

Fix vdes_sr to mirror channel.rs pipeline_rates(): use
audio_sample_rate.max(96_000) as the target rather than the hardcoded
96_000.  The two diverge when audio_sample_rate > 96_000, causing the
VdesDecoder to use the wrong symbol-to-sample ratio.

Move persistent history from trx-client to trx-server where decode
events originate. History for AIS, VDES, APRS, CW, FT8, and WSPR is

DecoderHistories and replayed to connecting clients, consistent with
all other decoder types.

sjg 1001786a08 [fix](trx-backend-soapysdr): ensure IQ stream recovery after overflow
Two problems prevented reliable recovery after a persistent overflow:

1. Restart storm: once read_error_streak >= 3, every subsequent read
   failure triggered a deactivate/activate cycle, potentially preventing
   the hardware from stabilising. Fix: after a successful restart, reset
   read_error_streak to 1 so the stream gets 2 more failures before the
   next restart attempt.

2. Stuck-deactivated stream: if activate() failed after overflow, the
   stream was left deactivated. Subsequent reads returned non-overflow
   errors which handle_read_error ignored (Ok(false)), so the stream was
   never reactivated. Fix: add a high-streak fallback (>= 10 consecutive
   errors of any kind) that also attempts a full deactivate/activate
   restart, covering the stuck-deactivated case.

sjg bfc510e1eb [fix](trx-client,trx-server): fix spectrum death and stuck shutdown after IQ overflow
Two bugs triggered by a SoapySDR IQ overflow:

1. Spectrum dies permanently (trx-client): when GetSpectrum times out
   (300ms SPECTRUM_IO_TIMEOUT), the error was silently swallowed and
   the spectrum buffer cleared. The in-flight response remained in the
   TCP receive buffer, desynchronising all subsequent reads so every
   poll kept failing. Fix: propagate the error so handle_connection
   returns and the outer loop reconnects, restoring TCP sync.

2. CTRL+C hangs trx-server: after IQ overflow, the sdr-iq-read thread
   can get stuck in a blocking SoapySDR/USB call (deactivate/activate
   with no timeout). Tokio received SIGINT and aborted async tasks, but
   the process could not exit while the native thread was blocked in
   uninterruptible I/O. Fix: call std::process::exit(0) after the
   graceful shutdown sequence so the OS forcibly terminates all threads.

sjg 10f5a147dc [fix](trx-vdes): preserve higher SDR iq rate
Keep the SoapySDR VDES and MARINE IQ path at a much higher channel sample rate instead of collapsing toward the normal audio rate, so the decoder receives usable complex baseband for the 76.8 ksps VDES signal.

sjg 9fe293e056 [feat](trx-rs): expose marine mode and ft8 live bar
Add an FT8 live overlay bar, align APRS top controls with the other decoder tabs, advertise MARINE in the SoapySDR mode list, and make the VDES decoder emit raw unsynced diagnostic frames instead of dropping weak bursts outright.

sjg c8d81ed353 [feat](trx-rs): add marine mode scaffolding and VDES fallback
Keep weak VDES bursts visible by emitting unsynced diagnostic frames instead of dropping them, remove receiver badges from FT8 and WSPR history rows, and carry the current MARINE composite-mode scaffolding through the shared mode enums and backend mappings.

sjg 5e84fe2a82 [feat](trx-rs): add VDES hard-decision FEC stage
Improve the VDES decoder with sync/rotation metadata and a first hard-decision rate-1/2 Viterbi stage after deinterleaving, then surface the extra lock state in the VDES frontend. Also fix the strict clippy findings in AIS, frontend bookmarks, and the server audio stack signature.
