efitenandClaude Opus 5 d1b615fc0d fix(node-health): list only observers that heard the node on air (#2057)
Closes #2056.

## What changes

The node detail "Heard By" card now lists only observers that received
the node's **own transmission off the air**, and reports the rest as a
count.

```
HEARD BY — DIRECT (8 OBSERVERS)
OBSERVER                REGION  PACKETS  AVG SNR   AVG RSSI
BE-DUF-SiSCD-01         —        16276    7.9 dB   -108 dBm
BE-BRU-Moris  repeater  —        13775   -5.6 dB   -122 dBm
...
Seen via relay by 29 observers. Those observers heard a repeater that
forwarded this node's traffic, not this node.
```

and for a node nothing hears:

```
HEARD BY — DIRECT (0 OBSERVERS)
No observer is within radio range of this node.
Seen via relay by 2 observers. …
```

## The rule, and where it comes from

Read out of the firmware rather than assumed:

| | |
|---|---|
| `Packet.h:83` | `setPathHashSizeAndCount(sz,n) { path_len =
((sz-1)<<6) \| (n&63); }` — hash size rides in the packet's `path_len`
byte |
| `Mesh.cpp:649,678` | only `sendFlood()` sets it, so the **originator**
decides; `CommonCLI.h:69` defaults `path_hash_mode = 0`, i.e. one byte |
| `Mesh.cpp:349` | a forwarding repeater appends its hash with the
packet's size — it cannot upgrade a packet, and the **last hop is who
was heard** |
| `Mesh.cpp:89,103` | on a direct route a forwarder matches the head of
the path and calls `removeSelfFromPath` before retransmitting, so the
path is the **remaining** route and the transmitter is not in it |

So an observation credits exactly one node:

1. Route type must be `ROUTE_TYPE_FLOOD` or
`ROUTE_TYPE_TRANSPORT_FLOOD`. Direct routes never qualify (38% of
transmissions over 7 days).
2. Empty path → the originator, known only for ADVERTs.
3. Otherwise the last hop.
4. The hop must resolve to exactly one candidate. Same gate
`resolvePathForObsColdLoad` already applies: under-attribute rather than
guess. It drops 418,530 of 1,455,721 flood observations with a path over
7 days (28.8%), and it is what stops the wrong-band credits.

## Measured effect

| node | before | after |
|---|---|---|
| BE-BRU-Moris | 36 observers | 3 |
| BE-KRO-RP01 \| ON1KW | 40 | 3 |
| BE-BRE-ON8AR | 38 | 2 |
| NL-BXE-RP01 \| 433 | 35 | 0 |

Network-wide over 7 days, 234 of 1,860 nodes have at least one direct
observer (161 have exactly one, maximum 8). The direct list is therefore
empty for most nodes, with the relay count below it. That is the correct
reading: no observer is in radio range of them.

Independent corroboration on staging: for BE-WIL-3EIK-01 the eight
direct observers are exactly the top eight entries of its Neighbors
table by score and observation count.

## Perf justification

`GetNodeHealth` is fast today precisely because it never walks
observations — it uses one representative observation per transmission.
Direct-RF needs the per-observation path, and that cannot be a
per-request walk: the reference store holds **232,928 transmissions /
2,887,861 observations**, one node's `byNode` slice alone holds **55,458
transmissions / 1,450,544 observations**, and
`/api/nodes/bulk-health?limit=200` would multiply that.

So the aggregate is rebuilt by a background recomputer on the existing
`newAnalyticsRecomputer` pattern, published into an `atomic.Value`.
Reads are `O(direct observers)`, which is **cheaper than before** — the
old code built per-observer sums over every transmission in `byNode` on
every request.

Proof, `BenchmarkBuildDirectHeardIndex`:

```
BenchmarkBuildDirectHeardIndex-12    1    63067900 ns/op
```

3,000,000 observations (60,000 transmissions × 50 observations, 8-hop
paths, 64 candidate repeaters) in **63 ms**, once per recompute
interval.

Per observation the walk does one route-type check, one backward scan of
`PathJSON` for the last quoted token (no allocation, no
`json.Unmarshal`), one prefix-map lookup and one counter update.

Rebuilding wholesale also means eviction needs no bookkeeping: a pass
simply does not see evicted transmissions. The alternative — a field on
`StoreObs` updated incrementally — would have needed the call at five
construction sites (`store.go:942,1264,2854,3179`,
`chunked_load.go:609`), which is the duplication that caused #1558, plus
matching decrements at eviction.

## API

Both `GetNodeHealth` and `GetBulkHealth` carried a near-identical copy
of the observer loop; they now share one builder.

- `observers` — direct-RF only. Same field names, so no client
migration. Rows are a named `HealthObserverRow` instead of
`map[string]interface{}` (one fewer occurrence in a touched file, per
the AGENTS.md ratchet).
- `relayObserverCount` — new integer, observers that saw traffic through
the node without hearing it. `stats.totalPackets` and `stats.avgHops`
still count relayed traffic, so without this number the card would
contradict the figures printed beside it.

`docs/api-spec.md` is updated for both endpoints. It also documented an
`iata` field on these rows that the endpoint has never emitted; removed.

## Tests

- `cmd/server/direct_heard_test.go` — table test over the rule: flood
with empty path and known originator, flood whose last hop is the node,
flood whose last hop is another node, direct and transport-direct routes
(never credit), ambiguous last-hop prefix, listener-only candidate,
1-byte and 2-byte hop sizes; plus aggregation and row-building.
- `cmd/server/node_health_direct_rf_test.go` — end-to-end through the
handler: an observer that only saw relayed traffic must not appear in
`observers` but must be counted in `relayObserverCount`. Plus the
benchmark.
- `tests/unit/test-direct-rf-heard-by.js` — slices the card template out
of `public/nodes.js` and evaluates it, so it tests the shipped markup
rather than a copy: heading, empty state, relay line, singular/plural,
signal columns, listener/repeater badge tri-state.
- `cmd/server/node_health_can_relay_case_1290_test.go` — updated to seed
a genuinely direct reception, since a relay-only observer no longer
carries a badge.
- `cmd/server/analytics_recompute_after_load_test.go` — recomputer count
10 → 11.

Verified locally: `cmd/server` suite green, `sh test-all.sh` green (180
suites), `tests/e2e/test-e2e-playwright.js` 131/134 passed with 3
skipped and 0 failures against the seeded fixture, plus
`test-issue-1147-section-order-e2e.js`,
`test-issue-1151-orphan-separators-e2e.js` and
`test-issue-1281-location-row-e2e.js`, which all assert on this card.
`gofmt` clean, `vet` clean across all modules.

Browser-validated on staging: both the full detail page and the side
pane, on a node with 8 direct observers and on the 433 MHz node with
none. No console errors.

## What this does not do

`prefixMap.resolveWithContext` still guesses on ambiguous hops, so
paths, neighbor edges and analytics keep their current attribution.
Making it abstain is a much larger change and needs its own issue.

The "Regions" line and Region column on this card read `o.iata`, which
this endpoint has never emitted, so both have always been dead. Left as
found rather than widened into this change.

efitenandClaude Opus 5 52b9474d7a feat(map): filter repeaters by region name (#1862) (#2022)
Fixes #1862

## What

Adds a **Region Scope** picker to the map controls: pick `#be` and the
map keeps the nodes that declare `#be` or were seen carrying `#be`
traffic. It combines with the #2006 scope-state filter and persists in
localStorage the same way. While a region is picked, a small "Region:
#be · reset" chip sits on the map itself, so the filter stays visible
when the controls panel is collapsed (the default on phones) and can be
cleared from there.

## API

`/api/nodes` and `/api/nodes/{pubkey}` gain two fields on repeater/room
rows:

- `declared_regions`: named regions from the node's newest
declared-regions answer, split by the same function the Scope Audit now
uses for `declaredRegions` (`splitDeclaredRegions`,
`cmd/server/scope_config_state.go`), so both pages list a repeater under
the same names. `[]` means it answered and named no region. Absent means
it never answered, other roles, no declared-regions source, or the
declared-regions lookup failed.
- `declared_regions_truncated`: present, and `true`, only when that
answer was flagged as truncated, so the list is partial. Never `false`:
the `nodes.configured_scope` source does not record truncation, so
absence does not mean the list is complete.

The observed side reuses `transported_scopes`. Documented in
`docs/api-spec.md` and the served OpenAPI spec.

### Why no `?hashRegion=` query parameter
The observed side lives in the in-memory store. Filtering it after the
SQL `LIMIT`/`OFFSET` would corrupt `total` and paging, and the map pages
through `/api/nodes`. Same reasoning as the Data path section of #2001.

## Map behaviour

- Filtering is client-side over the nodes `fetchAllNodes` already
loaded: no new request. One pass over the loaded nodes to build the
picker counts, one Set lookup per node per render. The marker filter is
`nodePassesMapFilters` (`public/map.js:219`) and the observer stand-down
`observerLayerShown` (`:212`), both exported and tested.
- The picker and hint count only nodes with a map position, the same
test the marker filter applies first, so a count never promises markers
the map cannot draw.
- The observer layer stands down while a region is picked, for the same
reason it does for the scope-state filter.
- The popup lists declared and observed regions separately. A truncated
declared answer carries the same `truncated` badge the Scope Audit
shows.
- Absence is not read as a finding: the hint under the picker says a
node left off the map is not proof it lacks the region.

## Tests

- Go: `node_declared_regions_api_test.go` covers `declared_regions` on
list and detail endpoints, the no-source case, agreement with
`/api/scope-audit`, `declared_regions_truncated` (truncated,
truncated-empty, complete, configured_scope-only, newer untruncated
answer, companion) and the OpenAPI schema.
- JS: `test-issue-1862-map-region-filter.js` (30 tests) covers the pure
pieces (evidence, counts, options, hint, popup rows,
`nodePassesMapFilters`, `observerLayerShown`) and, at page level, runs
the registered map page through `init()` and `loadNodes()` in a vm
sandbox: picker built from loaded nodes, markers filtered by a stored
region, observer pins standing down, popup rows, the change handler
persisting, and the chip showing, resetting and rendering its text as
text.
- Mutation-checked: removing the region check, the observer stand-down,
the picker build in `loadNodes`, the popup rows, the persist on change,
the chip reset, or the truncated flag (Go or JS) each fails a test.
`test-issue-2001-map-scope-state.js` still passes.
- `go test ./...` in `cmd/server` passes; `check-css-vars` and
`check-xss-sinks --diff` are clean.

## Staging validation
Build `c646310f`, Chrome, no console errors:
- Picking `#be`: chip "Region: #be · reset" at the top of the map, hint
"221 nodes with a map position have evidence for #be: 129 declare it,
191 seen carrying its traffic. Absence here is not proof: ...".
- Clicking reset: picker back to "All regions", stored choice cleared,
chip hidden.
- First version, same instance: `declared_regions` on 136 of 500
`/api/nodes` rows; returning to "All regions" blocked the main thread
5.4 s against 3.2 s for the existing Status filter returning to "All".
The review measured the region filter's own added work at about 0.08 ms
per render plus popup rows that are already built for every marker, so
most of that time is the existing full re-render.

## Not verified
- The chip placement at phone width, and on narrow desktop widths where
it may sit under the expanded controls panel.
- The truncated badge with real truncated answers (staging has none
today).
- `test-map-clustering.js` has one failing test on `upstream/master`
too; untouched here.
- Marker badges from the original issue body are not implemented; the
popup rows are the per-node display.

efitenandClaude Opus 5 efdb3ea0b3 feat(analytics): retransmission pressure over time (#1699) (#2023)
## Summary
Adds `GET /api/analytics/retransmissions` and a "Retransmission Pressure
(proxy)" chart on the Analytics Topology tab, implementing the metric
agreed in #1699: for each flood, the number of distinct repeaters in the
union of the paths of all its observations (`[A]`, `[A,B,C]`, `[A,D]`
gives 4), averaged per time bucket.

Topology is the tab that already shows hop counts and repeaters in
paths, so the chart sits there instead of in a new tab.

## Definition
- Flood routes only (`route_type` 0/1); TRACE excluded. Direct routes
carry the route still to travel (firmware
`src/Mesh.cpp:78-106,334-342`), zero-hop sends are direct
(`src/Mesh.cpp:717-737`), TRACE path bytes are SNR values
(`src/Mesh.cpp:59-61`, refused by `sendFlood` at
`src/Mesh.cpp:637-641`). Firmware commit 0679dbef.
- **Flood events, not hashes.** `transmissions.hash` is UNIQUE and the
packet hash excludes the path (`src/Packet.cpp:41-50`), so when the same
bytes flood again the observations land on the same transmission.
Observations are sorted by time and split into events wherever two
consecutive observations are more than 5 minutes apart. Each event is
counted on its own and bucketed by its first observation.
- Why 5 minutes: a node holds a flood for at most 32 s
(`src/Dispatcher.cpp:11,243-251`) plus a random retransmit delay. On
live over 7 days, 72,806 of 74,347 flood transmissions span 60 s or
less, and of 1,372,283 consecutive observation gaps, 52 fall between 60
s and 300 s against 1,823 above 300 s.
- Events that start before the store retention floor (now minus
`retentionHours`) are left out for every request shape. The store keeps
older observations only for hashes heard again recently, so they do not
represent that period. Eviction of those transmissions is tracked in
#2024.
- A flood event heard only with an empty path counts as 0 repeaters.
- **Prefixes are not resolved to nodes, and a prefix counts once per
event**, whether it repeats across observations or inside one path. On
live (7 days), a repeated 2-byte prefix inside one path occurs in 1.08%
of flood transmissions and 6,178 of 6,596 such repeats match exactly one
known node; for 3-byte it is 0.69% and 104 of 104. That is one node
forwarding again after its 160-slot cyclic duplicate filter dropped the
hash (`src/helpers/SimpleMeshTables.h:9,52-57`). A repeated 1-byte
prefix (44.9% of 1-byte transmissions) is mostly two nodes; counting it
once keeps the value a lower bound. `summary.one_byte_packets` reports
how many events that affects.
- Observations are stored once per observer and path per hash, so a
later event of the same hash only holds pairs not stored before; its
count is a lower bound too. On live these are 1,466 of 75,356 events
(1.9%), and they are kept in the average.
- Resolution was not used: on live, 1-byte observations nearly all have
`resolved_path` NULL, and cold load refuses context-based resolution of
history (`cmd/server/neighbor_persist.go:155-168`).
- Buckets `5m|15m|1h|6h|1d`. `region` filters on observers like
`/api/analytics/rf`, after the event split; a region with no known
observers is not filtered, the same as the other analytics endpoints.
`area` is not supported.

## Implementation
- `cmd/server/retransmission_pressure.go:255` `addPath`: scans path JSON
directly into a generation-stamped hash set, no allocation per
observation.
- `cmd/server/retransmission_pressure.go:367`
`computeRetransmissionPressure`: one pass under `s.mu.RLock`. Per flood
transmission it sorts the observations by cached parsed time into a
reused scratch slice, splits events and counts each in `addEvent`
(`:319`). O(T + O log k + H).
- `cmd/server/retransmission_pressure.go:470`
`GetRetransmissionPressure`: default shape from the recomputer (#1659
warm-up gate). Other shapes come from a typed TTL cache (max 64 entries)
cleared on new paths and eviction (`cmd/server/store.go:2289,2336`);
concurrent misses on one key share one compute through singleflight
(`store.go:204`).
- `cmd/server/retransmission_pressure.go:515` handler,
`cmd/server/routes.go:331`, `cmd/server/openapi.go:108`,
`docs/api-spec.md:1283`.
- `public/analytics.js:761` card, `:855` `renderRetransmissionChart`
(CSS variables only, lines break at missing buckets, caption states it
is a proxy, names the observer coverage bias, the once-per-flood prefix
rule and the 5 minute event split), `:829` loader with stale-response
guard.

## Performance
- `BenchmarkComputeRetransmissionPressure`, 50k transmissions x 20
observations, `-cpu 1`, i5-1335U: median 161 ms/op (132 ms/op before the
event split); first pass after startup with timestamps not yet parsed
192 ms/op. About 22 KB and 281 allocations per op.
- On staging the default shape is served from the recomputer in 0.3 s;
the post-load recompute of this recomputer took 994 ms on a
121k-transmission store (log line quoted in #2025). A 336h store would
be about twice that, every recompute interval, under the store read
lock.

## Tests
- `cmd/server/retransmission_pressure_test.go`: union counting (reporter
example, overlaps, once per event for 1/2/3-byte, width/case, growth);
route/TRACE/zero-hop filter, bucketing, window by event start; event
split and the 5 minute settle gap (boundary, chained steps, unsorted
input), retention floor; region filter, region applied after the split,
unknown region, 1-byte share; recomputer read, TTL cache invalidation on
new paths and on eviction, cache expiry, singleflight, recomputer gate
wiring, handler, warm-up gate.
- `test-issue-1699-retransmission-chart.js` (33 tests, registered in
`test-all.sh` and `deploy.yml`).
- Mutation-checked: 18 mutations of the event split, floor, prefix rule,
bucketing, region order, cache clears, expiry, gate wiring and
singleflight, all killed.
- `go test ./...` in cmd/server passes; `scripts/check-css-vars.js` OK.

## Staging validation
Build `c646310f` (this rework plus #2025 and the other review
follow-ups), after a container restart and full load: default shape
74,974 flood events, average 27.08 repeaters, 169 hourly buckets from
2026-09-06 16:00 (the 168h floor) to the current hour, highest hourly
average 53.3. Before the rework the same instance showed buckets back to
2026-07-18, averages up to 148, and for the first minutes after a
restart only 5,911 packets.

## Merge order with #2025
#2025 fixes the recomputer startup for all analytics endpoints (the
stale first snapshot seen here). Whichever of the two merges second has
to add `recompRetransmissions` to `analyticsRecomputersLocked`, wire it
to that PR's `loadedGate` instead of `LoadComplete`, bump the recomputer
count in `TestAnalyticsRecomputers_PostLoadOrder` from 9 to 10, and make
`TestStartAnalyticsRecomputers_RetransmissionsGatedOnLoadComplete` call
`signalStartupLoadDone()`. That resolution is what ran on staging.

## Not verified
- Recompute timing on a production-size (336h) store; only extrapolated.
- Phone-width layout and dark theme of the reworked chart.
- E2E Playwright suite.

Fixes #1699

914bd4cf0e feat(channels): show each message's region (#1851) (#2018)
## Show each channel message's region scope

Each message in the Channels view now shows the region scope it was sent
with, as a small chip in the meta line: the region name (for example
`#be`), `unknown scope`, or nothing.

This is the channel-message part of #1852 by @dborup, extracted as a
focused change. #1852 was closed unmerged because it had grown to the
whole fork diff. The implementation follows dborup's commits c686ae3f,
350bf7ee and a94d57ed on dborup/CoreScope, adapted to current master.
dborup is co-author on the commit.

### What changed
- `cmd/server/db.go:2099,2195`: `GetChannelMessages` selects
`t.scope_name` when the column exists and returns it as `scope_name`.
- `cmd/server/store.go:5654`: the in-memory `GetChannelMessages` returns
`scope_name`, so the field does not depend on which path serves the
endpoint.
- `cmd/server/store.go:2966,3244`: both WebSocket broadcast builders
carry `scope_name`, so a live message shows its region immediately.
- `public/channels.js:342,2278`: `messageScopeChipHtml` renders the chip
with the existing `.sa-chip-declared` / `.sa-chip-unmatched` styles from
`scope-audit.css`. The name goes through `escapeHtml`. No new CSS.
- `public/channels.js:678,695,1435,1487`: the decrypt path and the
WebSocket path keep `scope_name` on the message.

### Differences from #1852
- The field is `scope_name`, the name `/api/packets` already uses.
- No `routeType` field. `transmissions.scope_name` already tells the
states apart: NULL means no transport code, an empty string means a
transport code that no configured region key matched. The frontend uses
`??`, not `||`, so the empty string is kept.
- A chip instead of `scope: <name>` text. The area label from later
#1852 commits is not included.

### Perf
One extra column per observation row in the page query (at most `limit`
transmissions), and one extra map entry per broadcast observation. No
new queries, loops or API calls.

### Tests
- `cmd/server/channel_message_scope_name_test.go`: the three states
through the DB query, the store, `/api/channels/{hash}/messages` over
both paths, a schema without the column, and both broadcast builders. 5
of its 6 tests fail without the change; the sixth guards the
missing-column case and passes either way.
- `test-issue-1851-channel-message-scope.js`: the REST, WebSocket and
client-side decrypt paths, escaping, and the name / unknown / none
render. 4/4 fail without the change. Registered in `test-all.sh` and the
unit step of `deploy.yml`.
- Mutation checks: returning `nil` for `scope_name` in the DB path fails
the DB and endpoint tests; `||` instead of `??` in the WebSocket path
fails the WebSocket test.
- `go test ./...` in `cmd/server`: ok. gofmt and go vet clean.

### Browser validation
On a staging instance with live traffic (build `e84d2da6`), in Chrome:
- `/api/channels/{hash}/messages` carries the `scope_name` key on every
message in the 19 channels whose results I read. `#hamradio`, latest 50:
34 named, 1 empty string, 15 NULL.
- Opening `#hamradio` renders 104 chips: `#nl` 53, `#be` 32, `#de` 11,
`#eu` 6, `#bx` 1 and `unknown scope` 1, and no chip on unscoped
messages. Chip text `rgb(26, 26, 46)` on `rgb(238, 242, 255)` in the
light theme.

### Not verified
- Dark theme not checked.
- The real-decrypt branch of `decryptCandidates` has no test and was not
exercised in the browser; the already-decrypted branch is tested.
- Messages already in the client decrypt cache show no chip until they
are decrypted again.
- `go test -race` and the Playwright E2E suite were not run locally.

Fixes #1851



## Review follow-up (commit `50346589`)

An independent review found no correctness or XSS problem and confirmed
DB, store and WebSocket agree on the value. Changed:

- **Real decrypt branch tested.** A new test runs the real AES+HMAC
decrypt branch in `decryptCandidates` with one packet per scope state;
deleting `scope_name` there now fails 2 of 7 tests.
- **Tooltip wording.** The unknown-scope tooltip now says the scope
"could not be matched to a single region on this instance"
(`public/channels.js:338-347`). The ingestor stores an empty name both
when no key matches and when several match without exactly one
operator-configured key (`cmd/ingestor/region_keys.go:364-393`), so
"matches none of the configured keys" was wrong for the second case.
- **Old decrypt cache.** Decrypted messages cached before this change
had no `scope_name` key and stayed chipless as long as the candidate
count did not change. A cached message missing the key now forces one
full decrypt; a cache that has it still takes the delta path. A test
covers each case.
- **Docs.** `docs/api-spec.md` documents `scope_name` on the channel
messages response, with the null / empty string / name semantics.

Corrections to the description:

- **Test counts.** With the `db.go` and `store.go` changes reverted, 4
of the 5 top-level Go tests fail (6 of 7 counting subtests); only the
missing-column test passes.
- **Broadcast payload.** `scope_name` is added to `pkt`, which is copied
into `broadcastMap` and also nested as `packet` (`store.go` ~2974-2980,
~3252-3257), so the key appears twice per observation: 36 bytes for
`null`, 48 bytes for `"#belgium"`.
- **Side effect on the Packets page.** The live table reads
`m.data.packet` (`packets.js` ~1316-1318), so flat rows and expanded
group children now show Scope for live packets. In grouped mode a new
group copies a fixed field list without `scope_name` (~1384-1395) and
shows the empty placeholder until reload. Before this PR every live row
showed that placeholder, so this is not a regression.

The three copies of the three-state scope rendering (`app.js`,
`packets.js`, `channels.js`) are left as they are.

efitenandClaude Opus 5 a059299588 feat(node-analytics): hop-count statistics per node (#1812) (#2021)
## Summary
Adds per-node hop-count statistics so repeater operators can choose
`flood.max`, `flood.max.unscoped` and `flood.max.advert` from what their
node actually sees.

- New endpoint `GET /api/nodes/{pubkey}/hop_analytics?days=N`
(`cmd/server/routes.go:299`, `cmd/server/node_hop_analytics.go:312`),
separate from `/analytics` as requested in the issue.
- New card "Hop Count at This Node" on the node analytics page
(`public/node-hop-analytics.js`, wired at
`public/node-analytics.js:130,174`): histogram of hop counts with a box
plot on the same x axis, filters `flood.max` (default),
`flood.max.advert`, `flood.max.unscoped`, driven by the existing range
picker.
- The existing "Hop Distribution" chart is unchanged: it shows path
length at the observer, a different quantity.
- No `direct` tag, although the issue lists one: for DIRECT packets the
path is the remaining route and no flood limit applies, so there is no
hop count to report.

## Hop count definition (firmware 0679dbef)
- `src/helpers/RoutingPolicy.h:15-21`: limits compare
`getPathHashCount()`; `.unscoped` applies to route type FLOOD, `.advert`
to adverts.
- `src/Mesh.cpp:344-350`: `routeRecvPacket` checks with n hashes in the
path, then writes its own hash at index n. So hops = the node's
zero-based index in the path, no +1.
- `src/Mesh.cpp:265-285`: a node forwards a flood once;
`src/Mesh.cpp:651,680`: an originator never forwards its own flood.
- DIRECT packets are excluded: their path is the remaining route
(`src/Mesh.cpp:78-103,334-341`).

Response: `{timeRange, packets: [{hash, timestamp, hops, tags}],
ambiguous}`. Tags: `flood`, `scoped` or `unscoped`, `advert`. Documented
in `docs/api-spec.md:679` and `cmd/server/openapi.go:90`.

## Attribution
`cmd/server/node_hop_analytics.go:198-309`. The result depends only on
the observed paths, the prefix map and the neighbor graph, so it is the
same after a restart as after live ingest.

- Every observation of every flood packet in the window is read.
`byNode` holds the server resolver's pick at ingest and other picks
after a cold load; `byPathHop` indexes only each packet's longest path,
which for a busy relay often runs through another branch of the flood.
- A packet counts when the node's prefix sits at exactly one index
across its observations, and either the node is the only relay candidate
for that prefix (`prefixMap.relayCandidates`,
`cmd/server/store.go:6795`), or the hop resolves to the node under the
ingestor's strict rule (`cmd/ingestor/path_resolver.go:143-214`) in at
least one observation and to another node in none. Strict rule: earlier
hops identified without a tiebreak, exactly one candidate adjacent in
`neighbor_edges` to the previous hop (the originator for hop 0 of an
advert), nodes already on the path excluded.
- The server resolver's tiebreaks (affinity, GPS distance, advert count,
pubkey order) are not used.
- Everything else with the node's prefix goes to `ambiguous`. In
practice that is most packets with a colliding 1-byte path hash.

On a read-only 7-day dump of a 1,669-node mesh DB, for one busy
repeater: 23,081 packets attributed, 11,437 ambiguous. Taking candidates
from `byPathHop` instead gave 9,995 attributed, with the histogram mode
moved from 2 to 3-5 hops.

## Performance
Scans `s.packets` under the read lock, no SQL per packet. Per
observation: one substring test for the node's first prefix byte; the
hop scan only for observations containing it; the strict walk only for
colliding prefixes, with per-request caches for candidates and
adjacency. `BenchmarkNodeHopPackets` models one 7-day request at that
scale (73,782 flood packets, 1,430,280 observations): 44-87 ms/op, 13.4
MB, 40 allocs on a throttling laptop.

Response size for that repeater over 7 days: about 23k entries, 2.3 MB
JSON, 375 KB gzipped. `hash` and `timestamp` are 61% of the raw and 91%
of the gzipped bytes; they stay because the issue asks for them so a
client can join entries to packets and bin by time.

## Tests
- Go: `cmd/server/node_hop_analytics_test.go`: 12 unit tests, a
live-ingest test through `IngestNewFromDB` (a colliding prefix without
independent attribution goes to `ambiguous`, not to the node the
resolver picked), live ingest versus cold load of the same DB, route
test, benchmark. 15 mutations of the attribution logic each fail a test.
- JS: `test-node-hop-analytics.js` (filters, histogram, quartiles and
whiskers with a fixture that separates 1.5 IQR from 3 IQR, render),
registered in `test-all.sh` and `.github/workflows/deploy.yml`.
- `gofmt`, `go vet ./...`, `go test ./...` in `cmd/server`,
`scripts/check-css-vars.js` pass.

## Staging validation
Build `c646310f` (this PR's review follow-up together with the other
open follow-ups), after a container restart and full load, on a busy
Belgian repeater:

- `hop_analytics?days=7`: 23,302 packets, 11,548 ambiguous, median 4,
adverts never above hop 7 (matching the firmware default
`flood_max_advert = 8`, `examples/simple_repeater/MyMesh.cpp:922`), 1.2
s. The first version reported 23,035 packets and 86 ambiguous in 534 ms,
because it trusted the resolver's pick for colliding prefixes.
- The card rendered on the first version with no console errors; the
rework does not touch the frontend beyond a test fixture.

## Not verified
- Response time and lock hold for 30 days on the busiest node on a
14-day store.
- Server relay candidates exclude companions and listeners while the
ingestor's prefix index does not, so a few strict attributions can
differ from the ingestor's persisted `resolved_path`.
- Identical numbers across a second container restart were shown in a Go
test, not repeated on staging.
- Dark theme, phone width, and switching the range picker in the
browser.
- Filter state is not reflected in the URL hash (the range picker is not
either).

Fixes #1812

efitenandClaude Opus 5 0fea3f2a75 feat(analytics): break scope adverts down by node role (#1979) (#2019)
## Summary

Adds a breakdown of flood adverts by sender role to `/api/scope-stats`
and the Scopes tab, in the descriptive shape agreed in #1979: per node
role, how many flood adverts were unscoped, scoped with an unnamed
region, or scoped with a named region. It reports what was sent, not
why.

## Changes

- `cmd/server/db.go:3114-3144`: one grouped query in `GetScopeStats`.
ADVERT packets on flood routes (TRANSPORT_FLOOD 0, FLOOD 1) in the
window, `LEFT JOIN nodes` on `from_pubkey`, split by the three
`scope_name` states (NULL, empty string, name). A missing or empty role
becomes `"unknown"`. Ordered by total descending, then role. Zero-hop
adverts are excluded because firmware sends them as
DIRECT/TRANSPORT_DIRECT (`src/Mesh.cpp:717-730`, `Mesh::sendZeroHop`),
so they would inflate "unscoped".
- `cmd/server/types.go:116-133`: `ScopeAdvertRoleCount` and
`ScopeStatsResponse.AdvertsByRole` (`advertsByRole`, always an array).
- `public/analytics.js:4760`: `scopeAdvertsByRoleHtml` renders a table
under the time-series chart with the count per state and its share of
the row. Role text is escaped. It reuses the existing `/scope-stats`
response, so there is no extra request.
- `docs/api-spec.md:1763-1786`: documents the new field.
`/api/scope-stats` is in `openapi_known_gaps.json`, so there is no
`openapi.go` entry to update.

API addition (existing fields unchanged):

    "advertsByRole": [
{ "role": "repeater", "unscoped": 7741, "unknownScope": 7, "named": 1562
}
    ]

## Performance

The query runs inside `GetScopeStats`, so it shares the existing 30s
cache per window. The unary `+` on `payload_type` keeps SQLite on the
`first_seen` range index. Without it the planner picked the
`payload_type` index and walked every stored advert whatever the window.
Read-only timing on a production DB (1,063,345 transmissions, 161,634
adverts, sqlite3 CLI 3.45.1):

| Window | payload_type index | first_seen index (this PR) |
|---|---|---|
| 7d | 0.231s | 0.059s |
| 24h | 0.214s | 0.008s |
| 1h | 0.213s | 0.001s |

## Tests

- `TestGetScopeStatsAdvertsByRole` (`cmd/server/db_test.go:2295`): the
three states, flood-only routes, non-advert and out-of-window exclusion,
`unknown` for a missing node row, an empty role and a NULL
`from_pubkey`, and ordering. Mutation checked: widening to routes 0-3
and dropping the empty-role fallback both fail it.
- `TestGetScopeStatsAdvertsByRoleEmpty` (`:2372`): empty result is `[]`,
not null.
- `test-issue-1979-scope-adverts-by-role.js`: renders the real
`analytics.js` helper in a vm sandbox. Covers row order, totals and
shares, columns, escaping (mutation checked), the empty state, and the
non-causal caption. Registered in `test-all.sh` and the deploy.yml unit
step.
- `go test ./...` in `cmd/server` passes, gofmt and go vet are clean,
`check-css-vars.js` OK, `check-xss-sinks.sh --diff` exits 0.

## Browser validation

On a staging instance with live traffic (build `139e484e`, together with
#1074's branch), in Chrome, no console errors: `/#/analytics?tab=scopes`
shows "Flood adverts by node role" under the time-series chart with its
caption, and a table of 6 roles for the default window, for example
`repeater 1.361 | 1.109 (81.5%) | 2 (0.1%) | 250 (18.4%)`. Shares in
each row add up to 100%. `/api/scope-stats?window=7d` returns
`advertsByRole` with the same six roles.

## Not verified

- Timings are from the sqlite3 CLI, not the modernc driver in the server
process.
- Role is the sender's current `nodes.role`. A node whose advert type
changed within the window is counted under its latest role. The data
also contains a raw `type-13` role, shown as is.
- Switching the window in the browser was not exercised; the API was
checked for 7d.
- No Playwright E2E added.

Fixes #1979



## Review follow-up (commit `43af46b8`)

An independent review found no correctness, security or performance
problem: counts are per transmission, the window matches the rest of the
Scopes tab, zero-hop adverts are DIRECT per firmware, and the
`+t.payload_type` hint holds on modernc SQLite 3.46.0. It found two test
gaps and a docs gap. Changed:

- **Ordering.** The Go fixture gave companion, repeater and unknown 3
adverts each, so ordering by total was never checked (`ORDER BY COUNT(*)
ASC` still passed). The fixture now has repeater 4, unknown 3, companion
2, sensor 2, so the expected order differs from alphabetical and the
companion/sensor tie checks the role-name tie-break. Reversing the count
order, dropping it, or reversing the tie-break now fails the test.
- **Column positions.** The JS test only checked that each cell string
appeared somewhere in the row, so swapping two columns passed. It now
compares each row's cells and the header cells by position; both swaps
fail.
- **Docs.** `docs/api-spec.md` and the `ScopeAdvertRoleCount` comment
now name every source of `unknown`: a NULL `from_pubkey` (legacy rows
the #1143 backfill has not reached), a sender with no `nodes` row,
including one moved to `inactive_nodes` by node retention (inside the 7d
window only with `retention.nodeDays` below 7), and an empty role.

Not added: a query-plan test pinning the `+t.payload_type` hint. The SQL
is inline in `GetScopeStats`, so the test would have to copy it or the
query would have to move into a constant; left for a follow-up if
wanted. The raw `type-13` role in the table is the ingestor's
placeholder for reserved advert types 5-15
(`cmd/ingestor/decoder.go:1229`, #1279), shown as is.

efiten 296456f9c1 feat(map): colour and filter repeaters by scope-configuration state (#2006)
Closes #2001. Two review rounds plus a re-review; findings and evidence on the PR. Verified on a deployment against live data: the field over 1653 nodes, marker tints per filter state, the marker title and popup Scope row reaching the DOM, and the colorblind-preset cascade. The audit and the map are held to the same classification by an end-to-end test that fails when either side's wildcard handling drifts.

efiten 8c164c5315 feat(scope-audit): verify a declared region against the repeater's own traffic (#1990)
Follow-up to #1987, and the point of counting that traffic in the first
place.

A region this instance holds no `hashRegions` key for is **unnameable,
not absent**. #1987 says so with a caveat chip. This settles it wherever
the evidence allows: derive `SHA256("#region")[:16]` from the repeater's
own declaration and HMAC that repeater's own unmatched packets with it.
Same computation the ingestor performs at ingest, with the candidate set
narrowed from every configured key to this repeater's handful of
declarations.

Where it fires, a grey "declared but not observed" chip becomes a green
one and the caveat count shrinks by the packets it explained.

## Two packets, not one

`code1` is two bytes, so an unrelated name matches a given packet with
probability 1/65536. Across ~400 unmatched packets and ~124 declared
names, chance alone produces roughly one false match per refresh. Two
matches on the same region for the same repeater is (1/65536)², about
one in four billion.

Lowering the threshold to one would not make this noisy, it would make
it **unsound**, so the constant carries that arithmetic and a test
rather than a comment. A region with exactly one hit stays grey and
reports its single hit, so the page can say why it is still shown as not
observed instead of leaving the reader to wonder.

## What it deliberately does not do

**It writes nothing.** Read-time only. A wrong answer expires with the
window instead of sitting in `transmissions.scope_name` until someone
runs a repair, and `cmd/server` stays read-only per the invariant in
AGENTS.md.

**`notObserved` remains the single source of chip colour.**
`regionEvidence` says only HOW a region was established. Two fields that
can disagree about the same fact is how this column got confusing in the
first place.

## Rule 0, including the part that was wrong at first

The naive shape is `targets × names × packets` HMACs: 205 × 124 × 400 ≈
10M.

Caching per `(region, transmission)` pair cuts the HMACs to ~50k. **That
measured 501ms**, because the HMACs had become a rounding error while
the *iteration* stayed cubic at 10.2M map lookups. Re-keyed per region,
holding the set of matching transmissions, it is **36ms** at the same
worst-case shape: a region is HMACed over every packet once, and a
target then asks one question per declared region instead of one per
(region, packet). Most declared regions match nothing, so the common
case is a single map lookup and no packet loop at all.

`hmacCount` exists so a test can assert the first mistake cannot come
back; the benchmark exists because only it caught the second.

## Both axes are bounded, because neither is bounded by the data

The "~400 packets in a 7 day window" this was sized against is a
property of one instance's configuration, not of the feature: the
ingestor stores the unnameable state for every transport-scoped packet
no configured key names, so an instance with few or no `hashRegions`
entries — the stock state, and the one this helps most — has **every**
scoped packet in that set.

- the window query takes the 4096 most recent candidates and reports
truncation, which the handler logs, so a grey chip on a sampled refresh
is not read as "not forwarded"
- the declared list is capped at 32 names per repeater: it arrives from
a collector that validates each entry's shape but never how many entries
there are
- measured at the cap: **306ms** for 205 targets over 124 names, against
29ms for the shape a real network produces

Because both caps make the evidence a sample, the response carries
`observedUnmatchedSampled`. Without it a client subtracts a capped
numerator from an uncapped total and overstates the unexplained traffic
with no way to know it is doing so. The chip subtracts only evidence for
regions **absent** from `notObserved` — a single-hit region the server
refused to accept is not called explained either — and says "at most N"
when the count was sampled.

## Verified on live data

Six repeaters clear the threshold in a 7d window on a real instance. One
of them: `nl-nb` green with 3 corroborating packets and the tooltip
stating the count, `belml` still grey on 1, and the caveat chip reading
31 of 34 packets unexplained rather than 30.

## Tests

`scope_verify_test.go` covers the HMAC-input walk against a real
transport-flood packet captured from a live instance (a hand-built
fixture would only prove the parser agrees with itself), that
`regionCode` does not fold case, the threshold in both directions, the
memo's HMAC count, both bounds with their truncation flag, and the
benchmark at cap size. Handler-level tests cover a region verified into
green, a single hit left grey with its count reported, and the
sample-size field.

`cd cmd/server && go test ./...` passes (77s), frontend 723 assertions
pass, `go vet` and `gofmt -l` clean.

efiten 0605b1703a feat(scope-audit): count and surface the traffic this instance cannot name (#1987)
Follow-up to #1986, and the second half of the same problem.

`ScopeAuditForwarding` drops rows whose `scope_name` is the empty string
with a bare `continue`. That empty string is the ingestor's
"transport-scoped, but no configured region key matched `code1`" state
(`scopeNameForDB`), so those packets name no region and can never
satisfy a declared one. The consequence is on the page: **a repeater
forwarding a region this instance holds no `hashRegions` key for is
reported exactly like a repeater forwarding nothing at all.** The audit
presents a gap in the reader's own configuration as a finding about
someone else's hardware.

This counts them per target, exposes the count as
`observedUnmatchedPackets`, and renders it as a caveat chip beside the
scope chips.

## Why it is not a rare edge

Measured on a live instance before this landed: of 613 `notObserved`
entries across 205 repeaters, **260 named a region that never appeared
under any name in the whole 7-day window**. Two of them (`behss`,
`fm-112`) were hash-verified as genuinely forwarded traffic the instance
simply could not name: packet `0a065d41d51f1f77` decodes to
`code1=9209`, which is exactly the code `#fm-112` derives over that
packet's own payload.

That instance had 16 region keys configured against 124 distinct region
names its repeaters declare. A stock install has fewer.

## What the counter is not

It is deliberately **not** folded into `unscopedPackets`. The two are
opposites:

| | meaning | what governs it |
|---|---|---|
| `unscopedPackets` | the packet carried no scope at all (`scope_name`
SQL NULL) | the `*` wildcard |
| `observedUnmatchedPackets` | the packet IS scoped, this instance holds
no key for that region | nothing the repeater declares |

For the same reason the new count never feeds `wildcardContradiction`,
which counts only plain unscoped floods. `scopeNameForDB` in the
ingestor is the source of truth for that three-state encoding, and the
comments point there rather than restating it.

It is also distinct from `ambiguousHops`, and the distinction is the
point of the chip: that one is a pubkey-prefix collision between two
repeaters and is nobody's fault, this one is a missing entry in the
reader's own configuration and they can act on it. Saying which is which
is what stops someone investigating an innocent repeater.

## Frontend

The chip reuses the muted dashed treatment of `.sa-chip-ambiguous` on
purpose: both are caveats on the row's finding rather than findings
themselves, and neither may compete visually with the red/green scope
chips beside them.

It renders nothing for a non-numeric count. The value is
server-supplied, and a truthiness check would put the literal string
`NaN forwarded packets` on the page if that ever stopped holding.

## Docs

`docs/api-spec.md` had **no entry for `GET /api/scope-audit` at all**,
so this adds one: query parameter, full response shape, and the notes a
client needs (the three traps the per-node endpoint documents apply here
identically, `*` is never a scope, and "never asked" is not "declared
nothing"). The new field is documented there rather than in isolation.

## Tests

- the counter on a last-hop and on a mid-path hop
- an unmatched packet enters neither `agg.scopes` nor `unscopedPackets`,
which is the confusion this field exists to prevent
- the field on the API row
- six frontend cases: zero renders nothing, a missing field renders
nothing (older server), the chip carries its count and class, singular
and plural are both grammatical, the title names the cause and the fix,
and a non-numeric count renders nothing rather than `NaN`

`cd cmd/server && go test ./...` passes, frontend 712 assertions pass,
`go vet` and `gofmt -l` clean.

Rule 0: the counter is one increment on a branch that already existed as
a `continue`, inside a loop this PR does not change. No new query, no
new pass over the data.

efitenandClaude Opus 5 e7b3a2e77f chore(#1856): remove POST /api/packets, which has never worked (#1959)
Part 1 of #1856. Part 2 (the hash migration reporting false success) is
#1958.

## It has never worked

`handlePostPacket` writes to the server's DB handle, and that handle is
read-only. `cmd/server/db.go:106`:

```go
dsn := fmt.Sprintf("file:%s?mode=ro&_journal_mode=WAL&_busy_timeout=5000", path)
```

Every call answered `500 attempt to write a readonly database`.

**This is the second report.** #1196 raised it on 2026-06-13, a fix was
merged that corrected v2 column names to v3, and the issue was closed.
That fix could not have worked, because the column names were never why
the write failed. Its comment is still sitting at `routes.go:1288`, next
to code that has never executed successfully in production.

## Why remove rather than build a handoff

**It cannot break a caller.** An endpoint that has only ever returned
500 has no working consumer. This is not a breaking API change, it is
documentation catching up with reality. Nothing in `public/` calls it.

**It was actively misleading.** `openapi.go` advertised it as "Ingest a
packet" and it sits behind `requireAPIKey`, which reads as a live,
protected write endpoint.

**Its test hid the breakage.** `TestPostPacketPersistsV3Schema` asserted
the observation row is written and passed for four months, because the
test DB is opened read-write while production is not. That is how #1196
came to be closed as fixed.

**Ingest is MQTT-only by design since #1283.** Re-adding an HTTP write
path re-opens the invariant that change established. If manual injection
is wanted later for testing or replay, it belongs on the ingestor side
and deserves its own issue. The repository already has the handoff shape
for that: the server writes `request-<id>.json` and the ingestor
consumes it (`cmd/ingestor/prune_geofilter.go`).

## What went

The route, `handlePostPacket` (103 lines), the now-unused
`PacketIngestResponse` type, the `openapi.go` entry, the round-trip
test, and the section plus table-of-contents line in `docs/api-spec.md`.
The `packetpath` import in `routes.go` became unused and went with it.

`+4/-225` across 6 files.

## The auth tests

The four `requireAPIKey` tests used `"/api/packets"` only as a request
path while building their own handler with `s.requireAPIKey(...)`, so
they never touched the route.

I checked that by **running them**, not by reading the code:

```
--- PASS: TestRequireAPIKey_RejectsWeakKey
--- PASS: TestRequireAPIKey_AcceptsStrongKey
--- PASS: TestRequireAPIKey_EmptyKeyDisablesEndpoints
--- PASS: TestRequireAPIKey_WrongKeyUnauthorized
```

Their paths now point at `/api/admin/prune-geo-filter`, which still
exists, so they no longer name a removed endpoint. Re-ran after that
change: still 4 of 4.

`/api/packets/observations` is a different endpoint and is untouched.

Verified: `gofmt` clean, `go vet` clean, `cmd/server` suite ok in 62.9s.

e2212f5015 feat(nodes): per-node Reach page + GET /api/nodes/{pubkey}/reach (v2, review-complete) (#1627)
Re-submission of #1625 (which was merged early, then reverted in #1626)
— now with **all three round-1 reviews addressed** so it lands in one
hardened state instead of as post-merge follow-ups.

## What

Per-node **Reach** view: a standalone page (`#/nodes/{pubkey}/reach`) +
a node-detail section + `GET /api/nodes/{pubkey}/reach`. It shows which
nodes a node has a **stable two-way RF link** with, derived from raw
`path_json` adjacency (a path travels origin→observer, so `[A,B]` ⇒ B
heard A). A link is bidirectional when both directions have
observations; the **bottleneck** (weaker direction) rates two-way
reliability. Nodes are identified only by **unique 2–3 byte** path
prefixes (1-byte collides → excluded).

## Review fixes folded in vs #1625

**Performance (Carmack):** hard scan LIMIT (200k) + modest prealloc;
`json.Unmarshal` replaced by a single-pass `parsePathTokens` (100k-row
scan 2.2M→1.3M allocs, 344→203ms); memoized resolver; size-hinted maps
(attribution over 100k rows: 102 allocs); `context.Context` plumbed;
cache `RWMutex` + evict-oldest (no full wipe); singleflight dedup;
degree/rank from a 60s shared snapshot; bench rewritten (ReportAllocs,
1k/10k/100k, mixed-payload, isolated attribution).

**Correctness/safety + tests (Independent + Kent Beck):** pubkey
validation → 400; error logging instead of silent swallow (first_seen /
degree / marshal→500 / discarded rows); `public_key=?` index use;
canonical `PayloadADVERT`; `min()` builtin; documented cache-slice
immutability; mux ordering comment. New tests: scanReachRows decode,
3-byte token branch, non-advert first-hop guard, observer SNR
aggregation across rows, HTTP-level attribution (asserts non-zero
we_hear/they_hear), 400/404/blacklist/cache-hit.

**UI / a11y / Tufte:** in-map legend (tiers + thresholds); dropped the
colour+width double-encoding (constant width, colour-only); colour-blind
glyphs (●●●/●●/●) + tier title beside the bottleneck number; dark-theme
`--link-*`; lighter table (horizontal rules, sentence-case headers); map
built once + link layer updated in place on toggle (no flicker);
time-range no longer flashes a loader; `destroy()` generation guard;
statCard escaping; scoped `@media print` to `#nq-report`;
`fieldset/legend` + `for/id` toggles; `aria-pressed` / `aria-live` /
back-link `aria-label`; "distance (km)" + bottleneck tooltip + no-GPS
note; inline styles → CSS; decorative emoji removed.

**Docs:** api-spec documents the 5-min cache, 200k scan cap, and 400.

## Testing
- `cmd/server` full suite green; reach unit + endpoint + bench all pass.
- `eslint public/*.js` (no-undef) and the XSS-sink gate clean.
- E2E updated: request status checks + exact (non-tautological) toggle
assertions + hard map-render assert.

## TDD-history note (Kent Beck gate)

This branch carries production + tests together, not a fabricated
red→green sequence. That's deliberate: the branch was rebased onto
upstream and the intermediate SHAs were squashed, so reconstructing a
"failing-test-first" commit after the fact would be theatre, not
evidence — and rewriting history to stage it would be dishonest. The
behaviour is instead covered by a comprehensive, anti-tautological suite
(directional attribution edges, 3-byte token branch, non-advert
first-hop guard, observer SNR aggregation, HTTP-level attribution
asserting non-zero counts, scan-cap truncation, zero-reach 200-not-404,
companion mis-attribution, cache eviction). Requesting maintainer
acceptance of the work on test *substance* rather than commit
*choreography*; the net-new-UI exemption is not claimed for the server
endpoint.

efiten 9c5faab1e4 Revert "feat(nodes): per-node Reach page (#1625)" (#1626)
Reverts #1625.

#1625 was merged before the round-1 reviews (Independent / Kent Beck /
Tufte) were addressed. Reverting to land it cleanly: a fresh PR will
re-add the feature with the perf pass, the backend correctness/safety +
test-coverage fixes, and the UI/a11y (Tufte) batch folded in, so it goes
through review in a single hardened state rather than as a string of
post-merge follow-ups.

No functional loss — the feature returns in the replacement PR.

efitenandClaude Opus 4.8 47f85f6c4c feat(nodes): per-node Reach page + GET /api/nodes/{pubkey}/reach (directional link quality) (#1625)
## 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/`.

317b59ab10 feat: area-based visual node filter — attribute packets by transmitter GPS (#804) (#839)
## 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

2329639f45 feat: scoped/unscoped transport-route statistics (#899) (#915)
@
## 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 `#`).

Kpa-clawbotandCopilot 3ddd9662e6 docs: add formal API contract spec for all REST endpoints and WebSocket messages
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
