The globe wasn't rendering because initGlobe() used setTimeout(100)
which can race with the display:none removal by switchMode(). Both
GPS and WebSDR modes use requestAnimationFrame to wait for the browser
to compute layout before initializing Globe.gl.
- Replace setTimeout with RAF-based retry loop (up to 8 frames)
- Add try-catch around Globe() init with fallback message
- Match the proven pattern from GPS and WebSDR modes

- Fix globe destroyed on re-render by preserving canvas DOM node across
renderLocationCard() calls instead of recreating from scratch
- Reduce globe.gl camera minDistance (180->120) so globe is visible in
200px container
- Clear stale globeInstance ref when canvas is gone
- Enlarge CPU gauge (90->110px), percentage label (18->22px), core bars
(24->48px height), and detail text (11->12px)
- JS fetchLocation() now supplements server response with client-side
ObserverLocation.getShared() from localStorage when server returns
'default' or 'none', picking up manual coordinates from settings modal
- Location priority: GPS > config env vars > manual (localStorage) > default

- Add third location fallback to utils/constants (London 51.5074/-0.1278)
so location always resolves even without GPS or env vars configured
- Remove min-height from sys-card to eliminate wasted space
- Switch System Info to vertical key-value layout filling the card
- Clean up OS string (strip glibc suffix), use locale date for boot time
- Bump info grid font size from 11px to 12px for readability

Replace broken app.gps_state lookup with utils.gps.get_current_position()
and return GPS metadata (fix quality, satellites, accuracy). Shrink location
card to single-column with 200px globe, move System Info into row 2.

Add SVG arc gauge, per-core CPU bars, temperature sparkline, network
interface monitoring with bandwidth deltas, disk I/O rates, 3D globe
with observer location, weather overlay, battery/fan/throttle support,
and process grid layout. New /system/location and /system/weather endpoints.

Real-time dashboard for host metrics (CPU, memory, disk, temperatures),
active decoder process status, and SDR device enumeration via SSE streaming.
Auto-connects when entering the mode with graceful psutil fallback.

Switch decoder subprocess from text mode to binary mode and decode
each line with errors='replace' so corrupted radio bytes (e.g. 0xf7)
are substituted instead of raising UnicodeDecodeError after long runs.

The satellite dropdown had no change listener, so selecting a different
satellite never updated the pass list, timeline, countdown, or polar plot.

The .btn, .btn-sm, and .btn-ghost classes used by morse mode buttons
(TXT, CSV, Copy, Clear) were defined in core/components.css but the
stylesheet was never loaded in index.html, causing unstyled buttons.

When the stop POST timed out (5s), lifecycle was set to 'idle' on error,
allowing checkStatus to see running=true and reconnect SSE. Now:
- stop .then() stays in 'stopping' on timeout/error instead of going idle
- checkStatus skips reconnect when lifecycle is 'stopping' post-timeout
but still transitions to idle when server confirms running=false
- LOCAL_STOP_TIMEOUT_MS raised from 5s to 12s to match server cleanup time

The previous stopPromise guard only prevented new polls from being
dispatched. Polls already in-flight before stop was clicked could still
return with running=true and override the stopping lifecycle, causing
SSE reconnection and an apparent restart loop. Add a second guard in
the .then() handler to check stopPromise/lifecycle before acting.

Guard checkStatus() against in-flight stop to prevent status poller
from overriding stopping state and reconnecting SSE. Lower SNR floor
from 1.3 to 1.15 to accommodate weaker CW signals. Add SNR/noise_ref
to scope events and metrics for real-time threshold debugging.

Widen noise detector offset from ±100Hz to ±200Hz to reduce spectral
leakage into the noise reference, and scale threshold_multiplier for
SNR space (2.8 → 1.54) so real CW signals reliably trigger tone
detection instead of producing all-E's at 60 WPM.
Fix misleading "decoder startup" timeout message on stop requests and
increase stop timeout from 2.2s to 5s.

The previous magnitude-based threshold couldn't distinguish CW tone from
AGC-amplified inter-element silence — the Goertzel level stayed above
threshold permanently, preventing any tone OFF transitions and thus zero
character decodes.
Switch tone detection to use SNR (tone_mag / adjacent_band_noise_ref).
Both bands are equally amplified by AGC, so the ratio is gain-invariant.
Also replace the conditional noise_ref guard with unconditional blending
so the noise floor tracks actual ambient levels continuously.

Filter decoder-thread 'stopped' status events that race with the route
lifecycle, causing the frontend to drop back to idle on first start.
Pull noise floor upward using adjacent-frequency Goertzel reference when
warmup calibration runs before AGC converges, preventing permanent
tone-on with zero character decodes.

The multimon-ng MORSE_CW decoder never reliably decoded characters.
Switch live decode to use the existing morse_decoder_thread() which
wraps MorseDecoder with Goertzel tone detection, adaptive thresholds,
and proper timing estimation — eliminating multimon-ng, PTY plumbing,
and the relay thread from the CW pipeline entirely.

Add bufsize=0 to Popen for raw FileIO instead of BufferedReader, and
start decoder/stderr threads immediately before sleep+poll so stdout
is read without delay — matching the working pager pattern.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
BufferedReader.read(n) on non-interactive streams (Python 3.14) blocks
until the full n bytes accumulate, starving the decoder of real-time
PCM data. Use os.read() on the raw file descriptor instead, which
returns as soon as any data is available. Falls back to .read() for
file-like objects without fileno() (e.g. BytesIO in tests).
