## What
Adds a per-node **Reach** view that answers "how well does this specific
node hear, and get heard by, its neighbours?" — both as a standalone
page (`#/nodes/{pubkey}/reach`) and as a section on the node detail
page.
New endpoint: **`GET /api/nodes/{pubkey}/reach`**.
## What it measures
For the target node it derives, from raw `path_json` adjacency (a path
travels origin→observer, so in `[A,B]` B received A directly):
- **Directional link counts** per neighbour: `we_hear` (how often we
received them) vs `they_hear` (how often they received us).
- **Bidirectional / bottleneck**: a link is two-way stable when both
directions > 0; the weaker direction is the bottleneck and rates real
two-way reliability.
- **Importance**: neighbour degree + rank, relay-observation volume,
bidirectional-link count, direct-observer count.
- **Direct observers**: who received the node at 0 hops, with SNR.
Reliability rule: a neighbour is only attributed when its pubkey
**prefix is unique** at the path's byte length (collisions are skipped,
never misattributed).
## UI
- Standalone Reach page + node-detail section.
- Reusable bidirectional link map (OSM) with links coloured by
bottleneck.
- Incoming/outgoing toggles to isolate each direction.
## Naming note (deliberate, no collision)
This is distinct from the existing **per-observer reachability** in
topology analytics (`ReachNode` / `ObserverReach` / `perObserverReach`).
This PR adds its own `NodeReach*` response structs in a new
`node_reach.go` and a new `/api/nodes/{pubkey}/reach` route — there are
no symbol or route collisions (verified: `go build ./...` clean). Happy
to rename to disambiguate further (e.g. "Link Quality") if you'd prefer
to reserve "Reach" for the per-observer feature.
## Testing
- `cmd/server`: endpoint shape/404/limit-clamp + unit tests for token
derivation and directional attribution, plus a scan benchmark — all
pass.
- Frontend: helper tests + Reach-page E2E (`test-node-reach-e2e.js`),
standalone route + incoming/outgoing toggles.
- `go build ./...` and `eslint public/*.js` (no-undef) clean.
## Docs
Design spec, implementation plan, and the `GET
/api/nodes/{pubkey}/reach` API contract are included under `docs/`.

## Summary
- Adds configurable GPS polygon areas to `config.json`; nodes are
attributed to an area if their last-known position falls inside the
polygon
- New `Area: …` dropdown filter (matching the existing region filter
style) appears on all analytics, nodes, packets, map, and live screens
when areas are configured
- Backend resolves area membership with a 30s TTL cache; area filter
bypasses the 500-node cap on `/api/bulk-health` so all area nodes are
always returned
- Includes a polygon builder tool (`/area-map.html`) for drawing and
exporting area boundaries
## Changes
**Backend**
- `AreaEntry` type + `Areas` config field
- `GetNodePubkeysInArea` DB query + `resolveAreaNodes` (30s TTL,
`areaNodeMu` RWMutex)
- `PacketQuery.Area` + `filterPackets` polygon check
- `?area=` param propagated through all analytics, topology,
clock-health, and bulk-health routes
- `/api/config/areas` endpoint
**Frontend**
- `area-filter.js`: single-select dropdown, persists to localStorage,
cleans up stale keys on load
- Wired into analytics, nodes, packets, channels, map, and live pages
- Live map clears node markers on area change
**Docs & tools**
- `docs/user-guide/area-filter.md` — configuration and usage guide
- `docs/api-spec.md` — updated with new endpoint and `?area=` param
table
- `tools/area-map.html` — polygon builder for defining area boundaries
- Demo areas added to `config.example.json`
## Test plan
- [x] No areas configured → filter dropdown does not appear on any page
- [x] Areas configured → dropdown appears, "All" selected by default
- [x] Selecting an area filters nodes/packets/topology/map correctly
- [x] Selecting "All" restores unfiltered view
- [x] Selection persists across page reloads (localStorage)
- [x] Stale localStorage key (area removed from config) is cleared on
load
- [x] `/api/bulk-health?area=X` returns all nodes in area (no 500-node
cap)
- [x] `/api/config/areas` returns correct list

## What this PR does
Implements region-scoped transport-route packet tracking with two
sub-features:
### Feature 1 — Scope statistics (`scope_name`)
- At ingest, transport-route packets (route_type 0/3) with Code1 !=
`0000` are HMAC-matched against configured `hashRegions` keys (mirroring
the `hashChannels` pattern). Matched region name (or `""` for unknown)
stored in new `transmissions.scope_name` column via migration
`scope_name_v1`.
- New `GET /api/scope-stats?window=` endpoint (1h/24h/7d, 30s
server-side TTL) returning transport totals, scoped/unscoped counts,
per-region breakdown, and time-series.
- New **Scopes** tab in Analytics with summary cards, per-region table,
and two-line SVG chart. Auto-refreshes every 60s.
### Feature 2 — Node default scope (`default_scope`)
- Per-node `default_scope` column on `nodes`/`inactive_nodes` (migration
`nodes_default_scope_v1`) tracks the most recently matched region for
each node, derived from transport-scoped ADVERT packets.
- `GET /api/nodes` response includes `default_scope` field when column
is present.
- Node detail panel displays the default scope badge.
- Async startup backfill (`BackfillDefaultScopeAsync`) populates the
column for nodes with pre-existing ADVERT data.
### Config
Add `hashRegions` to `config.json` (see `config.example.json`). One
entry per region name (with or without leading `#`).

Document the exact response shape, query parameters, and type information
for every endpoint in server.js. This is the authoritative contract that
both Node.js and Go backends must conform to.
Covers:
- All 30+ REST endpoints with full JSON response schemas
- WebSocket message envelope and data shapes
- Shared object shapes (Packet, Observation, DecodedHeader, DecodedPath)
- Query parameter documentation with types and defaults
- Null rules, pagination conventions, error response format
- Frontend consumer matrix (which page reads which WS fields)
- Payload type and route type reference tables
