sjgandClaude Sonnet 4.6 22311eb01c [fix](trx-frontend-http): drop bidirectional requirement for decode paths
The bidirectional check required both A→B and B→A directed messages to
draw a contact line, which was too strict — the receiver may not hear
both sides of a QSO. Now a decode path is drawn whenever a directed
message is decoded and the target's locator is known from any message
in the 24 h history window.

Also rename "Longest QSOs" → "Longest decode paths" and update
related UI labels to better reflect what is actually shown.

Add hardware AGC on/off control for SoapySDR backend, wired through the
full stack from RigCommand to the web UI:

- RigCommand::SetSdrAgc(bool) + ClientCommand::SetSdrAgc in protocol
- set_sdr_agc() on RigCat trait (not-supported default)
- SoapySdrRig: agc_enabled field, set_sdr_agc() via pipeline agc_cmd,
  sdr_agc_enabled in filter_state(); removes the "not yet implemented"
  warning — gain_mode="auto" now properly enables hardware AGC via
  SoapySDR set_gain_mode()
- IqSource::set_gain_mode() trait method; RealIqSource implements it
- SdrPipeline: agc_cmd channel, read loop applies it each iteration
- POST /set_sdr_agc endpoint in trx-frontend-http
- New "SDR settings" full-row in index.html with Hardware AGC checkbox
  and RF Gain (moved out of WFM controls); row hidden when
  show_sdr_gain_control is false
- app.js: AGC checkbox handler, disables RF gain input while AGC is on,
  syncs checkbox state from filter.sdr_agc_enabled

sjgandClaude Sonnet 4.6 262e78e72b [fix](trx-backend-soapysdr): fix AM demodulation DC blocker, AGC, and add IQ AGC
Three issues caused audible distortion on AM reception:

1. DC blocker shared r=0.9999 (τ≈1.25 s at 8 kHz) across all modes.
   For AM the envelope detector outputs A_c+m(t) — always positive —
   so the blocker needs to track the carrier bias quickly.  AM now uses
   r=0.999 (τ≈125 ms), 10× faster, while keeping the highpass cutoff
   below 2 Hz so speech is unaffected.

2. Audio AGC time constants were inverted relative to good AM AGC design:
   attack=200 ms (should be fast to prevent overload) and
   release=3500 ms (unreasonably sluggish).  Changed to attack=5 ms /
   release=200 ms, target=0.5, max_gain=36 dB.

3. No IQ AGC before envelope detection meant carrier amplitude variation
   went directly into the audio chain, forcing the slow audio AGC to
   handle both RF level and audio level simultaneously.  Added an AM IQ
   AGC (attack=0.5 ms, release=50 ms, target=0.7, max=30 dB) that
   normalizes carrier power before demod_am, so the DC blocker always
   sees the same steady-state bias regardless of signal strength.

sjgandClaude Sonnet 4.6 b1f52bbfa5 [fix](trx-frontend-http): fix FT4/FT2/WSPR message container styling and cap DOM rows
Apply #ft8-messages container style (border, rounded corners, monospace
font, max-height with scroll) to #ft4-messages, #ft2-messages, and
#wspr-messages which were missing it.

Add #ft4-decode-toggle-btn and #ft2-decode-toggle-btn to the narrow-
screen white-space:nowrap media query rule alongside FT8/WSPR.

Cap DOM rows rendered per history view to 200 (FT8_MAX_DOM_ROWS,
FT4_MAX_DOM_ROWS, FT2_MAX_DOM_ROWS). Full history is retained in
memory; only the DOM representation is bounded. This prevents tab
switching from becoming sluggish after a long decode session where
thousands of rows accumulate in the DOM.

ab3bf9120e [fix](trx-backend-soapysdr): fix SSB demodulation with asymmetric complex BPF
Three bugs caused USB/LSB to sound like AM:

1. The IQ low-pass filter was symmetric (passband ±BW/2), so both
   sidebands were passed equally — taking .re then produced DSB-SC
   rather than SSB audio.

2. cutoff_hz was computed as bandwidth_hz/2, halving the usable audio
   bandwidth (1500 Hz for a 3 kHz USB channel).

3. demod_lsb claimed spectrum inversion was "handled upstream by
   negating channel_if_hz", but that negation was never applied; USB
   and LSB were functionally identical.

Fix: add a shift_norm parameter to build_fir_kernel / BlockFirFilterPair
that complex-modulates the time-domain FIR coefficients by
e^{j·2π·shift_norm·n}, shifting the passband in the frequency domain.
A new ssb_shift_norm() helper returns +cutoff_norm for USB/CW/DIG
([0, BW] Hz passband) and -cutoff_norm for LSB/CWR ([-BW, 0] Hz
passband); all other modes get 0.0 (symmetric LPF unchanged).

After the one-sided filter, taking .re correctly reconstructs the
selected sideband. No IF negation is needed for LSB.

Also fix two unit tests missing the force_mono_pcm argument introduced
after they were last updated.

sjgandClaude Sonnet 4.6 342adf476c [fix](trx-ft8): limit FT2 OSD-lite to prevent false decodes
The OSD-3 (triples) path over 5 LLR passes was doing ~11,600 CRC checks
per candidate. With a 14-bit CRC this gives ~0.7 expected false positives
per candidate — far too high.

Remove OSD-3 entirely. Cap max_candidates at 16 for OSD-1/OSD-2, giving
136 CRC checks per pass (680 total). Gate OSD-lite behind a check that
LDPC reached within 6 parity errors of converging, so it only fires when
the LLRs are already trustworthy. Combined false-positive rate drops to
~0.04 per near-miss candidate.

Also remove the now-unused ft2_osd_decode and ft2_codeword_distance
functions.

sjgandClaude Sonnet 4.6 eac2efdb35 [fix](trx-ft8): increase FT2 LDPC iterations and improve OSD fallback
Increase BP/SP iteration count from 30 to 50 to match WSJT-X reference
and give belief propagation more opportunities to converge near-threshold
candidates.

Replace the parity-based OSD-1/OSD-2 fallback (which required LDPC to
have nearly converged) with ft2_osd_lite_decode applied to all five LLR
combination passes. The CRC-based decoder works directly from raw LLRs
without depending on LDPC convergence, searching the 24 least-reliable
systematic bits for up to three bit errors via OSD-3.

Also increase max_candidates in ft2_osd_lite_decode from 12 to 24 for
broader coverage of likely error positions.

sjgandClaude Sonnet 4.6 3b28281684 [fix](trx-ft8): add OSD-1/OSD-2 to FT2 LDPC decode path
Diagnostic logging showed the FT2 BP/SP decoders consistently reach
1-8 residual parity errors rather than zero — the LLRs are correct
in direction but LDPC belief propagation stalls just short of
convergence.

Add ft2_osd_decode() implementing Ordered Statistics Decoding orders
1 and 2: after the five-pass BP/SP loop fails, sort the 174 codeword
bits by |LLR| ascending and trial-flip single bits (OSD-1, always)
or all pairs of the 50 least-reliable bits (OSD-2, when the remaining
error count is <= 4).  Each trial costs one O(83) parity check;
worst-case overhead is ~1300 checks per candidate, negligible next to
the 5 x 30-iteration BP/SP passes already performed.

Add err=N/N/N/N/N to the FT2 window diagnostic log line, showing the
minimum number of unsatisfied parity equations across all candidates
for each of the five LLR passes. This makes it possible to distinguish
between a signal-quality-limited failure (small error count) and a
systematic decoder bug (large error count), which is the key unknown
in diagnosing the current FT2 LDPC non-convergence.

sjgandClaude Sonnet 4.6 b9744ef8fd [feat](trx-frontend-http): color radio paths by band or mode
Radio paths and decode contact paths now use the same color as the
marker they belong to, respecting the active filter mode:
- Band mode: color follows the band (golden-angle HSL hue)
- Mode/source mode: color follows the source type (FT8/WSPR/bookmark)

APRS, AIS, and VDES paths use their fixed source colors unchanged.
Decode contact paths sync color when the filter mode is switched.

CSS stroke/stroke-opacity removed from path classes so Leaflet's
color option takes effect; dasharray and flow animation are retained.

sjgandClaude Sonnet 4.6 a3c098b68f [fix](trx-ft8): correct FT8 SNR to WSJT-X 2500 Hz convention
The score from ft8_lib is an averaged uint8 difference between Costas
sync tones and their neighbours (each unit = 0.5 dB). The previous
score * 0.5 gave the signal-above-adjacent-noise in dB relative to a
single 3.125 Hz waterfall bin, yielding values of +5 to +50 dB —
all wrong.

Subtract 10*log10(2500/3.125) ≈ 29 dB to normalise to the 2500 Hz
reference bandwidth used by WSJT-X and expected by PSKReporter:

  snr = score * 0.5 - 29.0

This maps score 10 (minimum decodable) → -24 dB and score 60 → +1 dB,
matching typical WSJT-X SNR report ranges.

sjgandClaude Sonnet 4.6 587ece9903 [fix](trx-backend-soapysdr): fix audio distortion from incorrect force_mono_pcm
Two bugs introduced by 60697bb:

1. dsp.rs passed `channel_idx == 0` as force_mono_pcm, which forced the
   primary pipeline channel to output mono samples. The Opus encoder was
   configured for stereo, so it received half the expected frame data,
   causing distortion for all connected audio clients.
   Fixed by passing `false` — hidden virtual channels already set
   force_mono_pcm=true via set_force_mono_pcm() in vchan_impl.rs.

2. main.rs short-circuited channel conversion when no audio clients were
   connected, sending raw frames to pcm_tx (decoders). When clients then
   connected, decoders switched to receiving stereo-interleaved frames,
   making decoder input format dependent on client presence.
   Fixed by always performing the channel conversion before sending to
   pcm_tx; the no-client skip now only bypasses Opus encode + rx_audio_tx.

- Add missing enterprise numbers (0x0000768F = 30351) to all enterprise
  field specifiers in both template blocks
- Fix sender template field IDs: use correct attributes (senderCallsign
  30351.1, frequency 30351.5, sNR 30351.6, iMD 30351.7, mode 30351.10,
  informationSource 30351.11, senderLocator 30351.3, flowStartSeconds 150)
- Fix sender data field order to match the template declaration
- Add iMD byte (0) required by the 8-field template
- Add 4-byte null padding on receiver and sender data records
- Batch spots into one UDP packet per 5-minute window (spec requirement)
- Deduplicate by callsign within each window (keep most-recent spot)
- Send template descriptors only in first 3 packets then once per hour
- Increment sequence number by report count, not packet count
- Guard against history replays: drop any spot older than the flush
  window (live FT8/WSPR is seconds old; history can be 24 h old)
