- Region filter container: remove margin-bottom, use inline-flex align
- Column dropdown checkboxes: 14x14px to match region dropdown
- Sort help ⓘ: use for newlines in title (\n doesn't render)
- Dark mode: .filter-bar .btn.active now retains accent background
(dark theme override was clobbering the active state)
- All filter-bar controls now exactly 34px tall with line-height:1 and border-radius:6px
- col-toggle-btn matched to same height/font-size as other controls
- Controls grouped into 4 logical sections (Filters, Display, Sort, Columns) with vertical separators
- Added title attributes with helpful descriptions to all controls
- Added sort help icon (ⓘ) with detailed tooltip explaining each sort mode
- Mobile responsive: separators hidden on small screens
All filter bar controls now share: height 34px, font-size 13px,
border-radius 6px, same padding. Region dropdown trigger matches
other controls, menu widened to 220px with white-space:nowrap to
prevent text wrapping.
When switching to a non-Observer sort, batch-fetches observations for
all visible multi-observation groups that haven't been expanded yet.
Header rows update immediately without needing manual expand.
Sort was only applied in pktToggleGroup and dropdown change handler.
Missing from: loadPackets restore (re-fetches children for expanded
groups) and WS update path (unshifts new observations). Now all
three paths call sortGroupChildren after modifying _children.
- Removed per-group sort bar links (broken navigation)
- Added global 'Sort:' dropdown in filter toolbar
- Persists to localStorage across sessions
- Re-sorts all expanded groups on change
Two sort modes for expanded packet groups:
- Observer: group by observer, earliest first, ascending time within
- Path length: shortest paths first, alphabetical observer within
Sort bar appears above expanded children with bold active mode.
- Deeplinks now use ?obs=<observation_id> which is unique per row,
fixing cases where same observer has multiple paths
- Added '🔍 Trace' link in detail pane actions
During _loadNormalized(), observations load in DESC order so the first
observation processed is the LATEST. tx.observer_id was set from this
latest observation. Added post-load pass that finds the earliest
observation by timestamp and sets tx.observer_id/path_json to match.
The WS handler was overwriting the group's path_json with the longest
path from any new observation. Header should always show the first
observer's path — individual observation paths are in the expanded rows.
Previously db.seed() ran unconditionally on startup and would populate
a fresh database with fake test data. Now seeding only triggers when
explicitly requested via --seed CLI flag or SEED_DB=true env var.
The seed functionality remains available for developers:
node server.js --seed
SEED_DB=true node server.js
node db.js (direct run still seeds)
When viewing a specific observation, the URL now includes ?obs=OBSERVER_ID.
Opening such a link auto-expands the group and selects the observation.
Copy Link button includes the obs parameter when an observation is selected.
Removed server-side longest-path override in /api/packets/:id that
replaced the transmission's path_json with the longest observation
path. The header should always reflect the first observer's path.
Individual observation paths are available in the observations array.
When expanding a grouped packet and clicking a child observation row,
the detail pane now shows that observation's observer, SNR/RSSI, path,
and timestamp instead of the parent packet's data.
Child rows use a new 'select-observation' action that builds a synthetic
packet object by overlaying observation-specific fields onto the parent
packet data (no extra API fetch needed).
When a later observation has an earlier timestamp, the transmission's
first_seen was updated but observer_id and path_json were not. This
caused the header row to show the wrong observer and path — whichever
MQTT message arrived first, not whichever observation was actually
earliest.
- Track lastActivityMs (Date.now()) on each channel object instead of ISO lastActivity
- 1s interval iterates channels[] array and updates DOM text only (no re-render)
- Uses data-channel-hash attribute to find time elements after DOM rebuilds
- Simple formatSecondsAgo: <60s→Xs, <3600s→Xm, <86400s→Xh, else Xd
- Seed lastActivityMs from API ISO string on initial load
- WS handler sets lastActivityMs = Date.now() on receipt
- Bump channels.js cache buster
The insert() method had a second code path (for building rows from
packetData) that pushed observations without checking for duplicates.
Added the same dedup check (observer_id + path_json) that exists in
the other insert path and in the load-from-DB path.
packet.timestamp is first_seen — when the transmission was originally
observed. When multiple observers re-see the same old packet, the
broadcast carries the original (stale) first_seen. For channel list
display, what matters is 'activity happened now', not 'packet was
first seen 10h ago'.
The UNIQUE index on (hash, observer_id, path_json) didn't prevent
duplicates when path_json was NULL because SQLite treats NULL != NULL
for uniqueness. Fixed by:
1. Using COALESCE(path_json, '') in the UNIQUE index expression
2. Adding migration to clean up existing duplicate rows
3. Adding NULL-safe dedup checks in PacketStore load and insert paths
Device clocks on MeshCore nodes are wildly inaccurate (off by hours or
epoch-near values like 4). The channel messages endpoint was using
sender_timestamp as part of the deduplication key, which could cause
messages to fail deduplication or incorrectly collide.
Changed dedupe key from sender:timestamp to sender:hash, which is the
correct unique identifier for a transmission.
Also added TIMESTAMP-AUDIT.md documenting all device timestamp usage.
WS messages from lincomatic bridge lack packet.timestamp, so the
code fell through to payload.sender_timestamp which reflects the
MeshCore device's clock (often wrong). Use current time as fallback.
timeAgo labels were computed once on render and never updated,
showing stale '11h ago' until next WS message triggered re-render.
Added 30s interval to re-render channel list, cleaned up on destroy.
Multiple observers seeing the same packet triggered separate message
entries. Now deduplicates by packet hash — additional observations
increment repeats count and add to observers list. Channel messageCount
also only bumps once per unique packet.
Instead of re-fetching /api/channels and /api/channels/:hash/messages
on every WebSocket event, the channels page now processes WS messages
client-side:
- Extract sender, text, channel, timestamp from WS payload
- Append new messages directly to local messages[] array
- Update channel list entries (lastActivity, lastSender, messageCount)
- Create new channel entries for previously unseen channels
- Deduplicate repeated observations of the same message
API calls now only happen on:
- Initial page load (loadChannels)
- Channel selection (selectChannel)
- Region filter change
This eliminates all polling and WS-triggered re-fetches.
The channels WS handler was calling invalidateApiCache() before
loadChannels()/refreshMessages(), which nuked the cache and forced
network fetches. Combined with the global WS onmessage handler also
invalidating /channels every 5s, this created excessive API traffic
when sitting idle on the channels page.
Changes:
- channels.js: Remove invalidateApiCache calls from WS handler, use
bust:true parameter instead to bypass cache only when WS triggers
- channels.js: Add bust parameter to loadChannels() and refreshMessages()
- app.js: Remove /channels from global WS cache invalidation (channels
page manages its own cache busting via its dedicated WS handler)
Timestamp is decoded from the ADVERT but never persisted to the nodes
table. The validation was rejecting valid nodes with slightly-off clocks
(28h future) and nodes broadcasting timestamp=4. No reason to gate on it.
Expanding a grouped row fired: packets?hash=X&expand=observations,
packets?hash=X&limit=1, and packets/HASH — all returning the same
data. Now uses single /packets/HASH call and passes prefetched data
to selectPacket() to skip redundant fetches.
The WS handler's 250ms debounce fired loadChannels() before the
global 5s cache invalidation timer cleared the stale entry, so
the fetch returned cached data. Now channels.js invalidates its
own cache entries immediately before re-fetching.
packets_v view uses observation IDs, not transmission IDs, so
getPacket(transmissionId) returned null. Skip the DB lookup entirely
and construct the row directly from the incoming packetData object
which already has all needed fields.
packets_v view uses transmission IDs, not packets table IDs.
insertPacket returns a packets table ID which doesn't exist in
packets_v, so getPacket returned null and new packets never got
indexed in memory. Use transmissionId from insertTransmission instead.
Create public/hop-resolver.js that mirrors the server's disambiguateHops()
algorithm (prefix index, forward/backward pass, distance sanity check).
Replace all /api/resolve-hops fetch calls in packets.js with local
HopResolver.resolve() calls. The resolver lazily fetches and caches the
full nodes list via /api/nodes on first use.
The server endpoint is kept as fallback but no longer called by the UI,
eliminating 40+ HTTP requests per session.
- Create packets_v SQL view joining transmissions+observations to match old packets schema
- Replace all SELECT FROM packets with packets_v in db.js, packet-store.js, server.js
- Update countPackets/countRecentPackets to query observations directly
- Update seed() to use insertTransmission instead of insertPacket
- Remove insertPacket from exports (no longer called)
- Keep packets table schema intact (not dropped yet, pending testing)
SQLite WAL auto-checkpoint (every 1000 pages/4MB) was causing 200ms+
event loop spikes on a 381MB database. This is synchronous I/O that
blocks the Node.js event loop unpredictably.
Fix: disable auto-checkpoint, run PASSIVE (non-blocking) checkpoint
every 5 minutes. PASSIVE won't stall readers or writers — it only
checkpoints pages that aren't currently in use.
