get_recent_packets/1 and get_recent_packets_for_map/1 now accept a
:cursor option (%{received_at: DateTime, id: uuid}) instead of :offset
for deep paging. On the 100M-row partitioned packets table, offset
scanning was linear in page depth; keyset is constant.
Ordering tightened to (received_at DESC, id DESC) so the cursor is
stable across ties. idx_packets_received_desc still covers the lookup;
a dedicated (received_at DESC, id DESC) index isn't worth its size
given microsecond timestamp granularity.
historical_loader migrated from batch_offset*batch_size scheduling to
a sequential cursor chain. The old loader fanned out N Process.send_after
batches up-front which could arrive out-of-order; the cursor version
waits for batch N before scheduling N+1, and also short-circuits the
remaining schedule when an under-full batch signals exhaustion.
mobile_channel load_historical_packets dropped its meaningless
`offset: 0`; callsign history already lacked offset.
No LiveView or WebSocket payload shapes changed. offset: 0 (or omitted)
still behaves as first page; non-zero offsets are silently ignored.
Turned on :error_handling, :underspecs, and :unmatched_returns in
mix.exs dialyzer config. The 97 warnings this surfaced were fixed in
place rather than suppressed:
- unmatched_return (79): explicit discard with `_ = ...` for
fire-and-forget side effects (Process.cancel_timer, :ets.new,
send/2), and pattern-matched `:ok = ...` for control-plane
Phoenix.PubSub subscribe/unsubscribe/broadcast calls so a future
return-shape change fails loud.
- contract_supertype (18): tightened @spec arg and return types on
data_builder, historical_loader, url_params, packet_utils,
encoding_utils, aprs_symbol, weather_controller, packet_replay to
match each function's actual success typing.
No behavioural change. mix compile clean, 1008 tests pass, dialyzer
count is now 0.
Historical map loading previously fetched all 73 columns (SELECT *) from
the packets table (~2068 bytes/row). Added get_recent_packets_for_map/1
with select_map_fields/1 that fetches only the 22 columns needed for map
rendering (~200 bytes/row), yielding a ~3x query speedup.
Also removes unused all_packets tracking from PacketProcessor and
simplifies visible_packets cleanup in Index.
Extract helper functions to reduce complexity in functions with
complexity 10-15:
- packet.ex: Extract add_symbol_data/2
Moves symbol data extraction into separate function
Reduces complexity from 10 to 9
- mobile_channel.ex: Extract bounds validation helpers
Creates all_numeric?/4, valid_latitudes?/2, valid_longitudes?/2
Moves complex boolean conditions into readable helper functions
Reduces complexity from 15 to within limits
- historical_loader.ex: Extract packet_has_valid_coordinates?/1
Moves coordinate validation logic with multiple conditions
Reduces complexity from 15 to within limits
Fixes 3 more Credo cyclomatic complexity issues.
Extract packet query logic into helper functions:
- query_historical_packets: Main query orchestration with error handling
- build_query_params: Build query parameters with callsign filtering
- maybe_include_latest_packet: Include latest packet for tracked callsigns
This breaks down the complex do_load_historical_batch function.

Ensure that when viewing a specific callsign (e.g., /w5isp), the most
recent position packet is always displayed, regardless of how old it is
or what historical time period is selected.
The fix ensures that during historical loading, if we're tracking a
specific callsign and it's the first batch, we always include the
callsign's most recent packet even if it falls outside the selected
historical time filter (1h, 3h, 6h, etc.).
This resolves the issue where callsigns with very old last positions
would not be visible when viewing their specific page.

Fix the issue where the historical data loading indicator would get stuck
indefinitely when no packets are found for a callsign or time period.
Changes:
- Handle empty packet results by properly updating loading state
- Add failsafe timeout (30s) to prevent infinite loading states
- Add debug logging to help identify when no packets are found
- Ensure loading progress is updated even when batches return no data
This fixes the issue where viewing callsigns with no recent data would
show "loading historical data" forever.

- Remove all CachedQueries usage throughout the codebase
- Replace with direct Packets module calls
- Delete CachedQueries module entirely
- Rename get_recent_packets_optimized to get_recent_packets
- Add has_weather_packets? function to Packets module
- Fix duplicate function definitions
- Update all test references to use new function names
This simplifies the codebase by removing the caching layer and
eliminates the database ownership errors in tests.

This commit addresses two major areas:
1. Crash Prevention & Error Handling:
- Added error handling to all database queries to prevent crashes
- Implemented circuit breaker pattern for APRS-IS connection
- Added timeouts to all Redis operations (5 second timeout)
- Fixed unsafe pattern matches that could cause MatchError crashes
- Added try/rescue blocks around background tasks
- Improved socket operation error handling with proper cleanup
- Enhanced packet cleanup worker with comprehensive error handling
2. RF Path Station Markers:
- Fixed issue where digipeater/iGate icons weren't shown when searching for callsigns
- Now loads and displays position markers for all stations in the RF path
- Extracts RF path stations from tracked callsign packets
- Fetches latest position for each digipeater/iGate
- Properly displays complete RF path visualization with station positions
Technical details:
- Added Process.alive? checks before sending messages
- Fixed resource cleanup in terminate functions
- Added proper error handling to File.read operations
- Implemented safe wrapper for ShutdownHandler health checks
- All changes ensure the app continues running even when errors occur

- Increase debounce time from 300ms to 400ms for bounds updates
- Cancel in-progress historical loading when new bounds are scheduled
- Add stale update detection to skip outdated bounds updates
- Clear timer reference and pending bounds when processing updates
- Add debug logging for cancelled loads and stale updates
This prevents overlapping historical data loads during rapid zoom
changes, eliminating duplicate packets and improving performance.

The function was sending a message but not returning the socket,
causing an ArgumentError when the result was passed to assign/3.
