The previous approach matched nodes via data packet hashes seen by
regional observers — but mesh packets propagate everywhere, so nearly
every node matched every region (550/558).
New approach: _advertByObserver index tracks which observers saw each
node's ADVERT packets. ADVERTs are local broadcasts that indicate
physical presence, so they're the correct signal for geographic filtering.
Also fixes role counts to reflect filtered results, not global totals.
Math.min(...arr) and Math.max(...arr) blow the call stack when arr
has tens of thousands of elements. Replaced with simple for-loop
arrMin/arrMax helpers.
Pills look out of place in the dense toolbar. Added { dropdown: true }
option to RegionFilter.init() to force dropdown mode regardless of
region count.
- Add aria-label and aria-haspopup='dialog' to BYOP trigger button
- Add aria-label to close button and textarea
- Add role='status' and aria-live='polite' to result container
- Add role='alert' to error messages for screen reader announcement
- Fix textarea focus style: visible outline instead of outline:none
- Update cache busters
- Separate region filtering from SNR filtering in /api/analytics/rf
- totalAllPackets now shows regional observation count (was global)
- Add totalTransmissions (unique hashes in regional set)
- Payload types and packet sizes use all regional data, not just SNR-filtered
- Signal stats (SNR, RSSI, scatter) use SNR-filtered subset
- Handle empty SNR/RSSI arrays gracefully (no Infinity/-Infinity)
- Fixes empty region dropdown (was populated before async regionMap loaded)
- Now uses multi-select RegionFilter component consistent with other pages
- Loads regions from /api/observers with proper async handling
- Supports multi-region filtering
The subagent used a non-existent column (sender_key) in the SQL join.
Reverted to the same byObserver + _nodeHashIndex approach used by
bulk-health and network-status endpoints.
The previous approach used pktStore._nodeHashIndex which only tracks
nodes appearing as sender/dest in decoded packet JSON. Most nodes only
send ADVERTs, so they had no entries in _nodeHashIndex and were filtered
out when a region was selected (showing 0 results).
Now uses a direct SQL join between observations and transmissions to find
all sender_keys observed by regional observers, which correctly includes
ADVERT-only nodes.
- Add RegionFilter.regionQueryString() to all API calls in renderSubpaths and renderNodesTab
- Add region filtering to /api/analytics/subpaths (filter packets by regional observer hashes)
- Add region filtering to /api/nodes/bulk-health (filter nodes by regional presence)
- Add region filtering to /api/nodes/network-status (filter node counts by region)
- Add region param to nodes lookup in hash collision tab
- Update cache keys to include region param for proper cache separation
Track current active tab in _currentTab variable so that
loadAnalytics() re-renders the current tab instead of always
resetting to 'overview' when region filter changes.
- Add 'Region:' label before filter controls
- ARIA roles: group with aria-label, checkbox roles on pills, aria-checked
- When >4 regions: render multi-select dropdown with checkboxes
- Trigger shows summary (All / selected names / N selected)
- All option at top, click-outside closes
- Pill bar mode unchanged for ≤4 regions (just added label + ARIA)
- channel-rainbow.json: 592 pre-computed SHA256-derived keys for common
channel names (cities, topics, ham radio, emergency, etc.)
- server.js: Load rainbow table at startup as lowest-priority key source
- config.example.json: Add #LongFast to hashChannels list
Key derivation verified against MeshCore source: SHA256('#name')[:16bytes].
Rainbow table boosted decryption from ~48% to ~88% in testing.
Channel keys for #test, #sf, #wardrive, #yo, #bot, #queer, #bookclub, #shtf
are all SHA256(channelName).slice(0,32) — no need to hardcode them. Move to
hashChannels array for auto-derivation. Only the MeshCore default public key
(8b3387e9c5cdea6ac9e5edbaa115cd72) needs explicit specification since it's
not derived from its channel name.
- Remove composite key scheme (ch_/unk_ prefixes) that broke URL routing
due to # in channel names. Use plain numeric channelHash as key instead.
- All packets with same hash byte go in one bucket; name is set from
first successful decryption.
- Add packet detail renderer for decoded CHAN type showing channel name,
sender, and sender timestamp.
- Update cache buster for packets.js.
The /api/channels endpoint was returning simple numeric hash (e.g. '45') while
/api/channels/:hash/messages was using composite keys (e.g. 'ch_#LongFast',
'unk_45') internally. This mismatch meant no channel ever matched, so all
messages appeared encrypted.
Fix: return the composite key as the hash field from /api/channels so the
frontend passes the correct identifier. Also add encodeURIComponent() to
channel API calls in the frontend since composite keys can contain '#'.
Adds mapDefaults config option with center and zoom properties.
New /api/config/map endpoint serves the defaults. live.js and map.js
fetch the config with fallback to hardcoded Bay Area defaults.
FixesKpa-clawbot/meshcore-analyzer#115
Channels sharing the same hash prefix but with different keys (e.g. #startrek
and #ai-bot both with hash 2d) now display the correct name by keying on the
actual channel name from decryption rather than just the hash byte.
FixesKpa-clawbot/meshcore-analyzer#108
~26% of observations were duplicates from multi-broker MQTT ingestion.
Added UNIQUE index to prevent future dupes, INSERT OR IGNORE to skip
silently, and in-memory dedup check in packet-store.
resolve-hops now accepts originLat/originLon params. Forward pass
starts from sender position so first ambiguous hop resolves to the
nearest node to the sender, not the observer.
