TeTeHackoandClaude Opus 5.5 417c8dd00a feat(observers): latest /neighbors report on the observers list and page (#2270, #2271) (#2300)
Closes #2270, closes #2271.

The ingestor took only the confirmed region scopes out of an observer's
`/neighbors` report (#1865) and dropped the rest. Nothing could
therefore say when an observer last reported, or whom it heard.

## Ingestor

`observer_neighbor_reports` (created in `dbschema.Apply`) keeps the
latest report of each observer, one row per observer, replaced by every
live report.

The report is unauthenticated, so `neighbors[]` is stored sanitised:

- only 64-hex keys
- `snr` and `heard_secs_ago` finite and in range
- `status` limited to `[a-z_]`
- `scopes` clamped
- at most 500 rows

`total_neighbors` is believed only when it is not below the number of
rows that arrived.

A **retained replay** only fills a missing row, and it is dated by the
report's own `timestamp`. After an ingestor restart, a long-dead
observer therefore does not look as if it just reported.

## API

The table is optional for the server (no `AssertReady` change); without
it the fields are simply absent.

- `GET /api/observers`: `neighbors_report_at` and `neighbors_count`,
from one batch query in the existing cached builder.
- `GET /api/observers/{id}`: also `neighbor_report`, which is
`{received_at, reported_at, neighbor_count, queried_neighbors,
self_scopes, self_default_scope, neighbors: [{pubkey, name, role, snr,
heard_secs_ago, status, scopes}]}`. Names and roles come from the node
table in one query.

## Frontend

`public/observer-neighbors.js` is shared by both pages and escapes
everything.

- **#2270, observers list:** a sortable **Neighbors** column, e.g. `3h
ago · 12`, or `—` when the observer never reported. The same value
appears in the slide-over.
- **#2270, observer page:** **Neighbors Report** and **Neighbors** stat
cards.
- **#2271, observer page:** a **Neighbors** table listing each neighbor
by name (a link to the node) or key prefix, with SNR, heard, scope query
status and scopes. The heading says when the list is shorter than the
count, e.g. `(2 of 3 listed)`.

## Tests

- **ingestor:** sanitising, the cap, live replace, the retained rules
(fill only, dated by the report, undated ignored) and the MQTT topic end
to end. The existing #1865 scope tests are unchanged and still pass.
- **server:** the list summary, the detail with names, and both
endpoints without the table.
- **frontend:**
  - unit tests of the helpers
- an XSS case for every rendered field; I checked that it fails when
escaping is removed
- `test-observers-headings` now expects the new column after `Last
Packet`
- **E2E:** `test-observer-neighbors-2270-e2e.js` intercepts the observer
endpoints, since the fixture has no reports. It is listed in
`scripts/non-unit-tests.json` and on shard 2.

Gates that pass:

- `go test -race` in `cmd/server`, `cmd/ingestor` and
`internal/dbschema`
- `sh test-all.sh`
- `eslint@8`, with 0 errors
- the XSS diff gate
- these E2E suites: the new one,
`test-issue-1639-observers-sort-e2e.js`,
`test-observer-iata-1188-e2e.js` and `test-e2e-playwright.js`

Performance: the list adds one primary-key-sized query per cache fill,
and the detail adds two small queries per request.

Also fixes #2330 (folded in from #2337, second commit).

n30nexandn30nex 202bafea28 fix(observers): show metadata while analytics loads (#2339)
Partial follow-up to #1778, limited to observer details; other pages
remain separate.

Observer identity, status and radio information now render when the
basic request finishes. Analytics and clock calibration load into their
own regions, so either can finish first. An analytics failure preserves
usable metadata. Identity failures and obsolete responses cannot
overwrite the current view, and failed chart construction is cleaned up.

The same three requests start together. Generation ownership, request
deduplication, date-window behavior and disposal remain covered. No new
fetches, settings, dependencies or customizer options; secondary replies
preserve the actual metadata DOM node.

[RED

proves 14 new assertion failures while all 11 existing unit cases pass.
Local RED browsers reproduce 20 new failures while all 32 old cases
pass. GREEN `52eabad7` passes 221 standalone suites, 28 ownership unit
checks and 56 browser cases across desktop/mobile and both themes; the
parent independently repeated the 56 browser cases.

All three independent review roles passed. Held-response assertions
prove the rendering behavior without claiming a server-latency speedup.
[Final

passes on this exact head, including all three browser shards, the
repeated slide-over stability gate and the architecture build.

n30nexandn30nex 1ed5e4ab3f fix(compare): exclude observer TX-only packets from overlap (#2346)
Red commit: `39295da8` ([intended CI assertion
failure](https://github.com/Kpa-clawbot/CoreScope/actions/runs/40605770951/job/122544822813)).
Green commit: `d1bda496`.

Observer comparison counted an observer's TX-only packets as receptions,
producing false overlap. It now requests `excludeTx=true`: the selected
observer and non-TX direction must match the same observation in memory
and SQLite v2/v3. Normal packet lists and stored TX records remain
unchanged; missing directions retain legacy compatibility.

Refs #667. This completes a comparison slice, not the issue's remaining
observer counters or #671's fleet/SNR feature. Representative display
fields and existing time-filter semantics are unchanged. API/OpenAPI
docs describe the filter and multi-node bypass.

Validation:
- RED: Go tests compiled with 32 intended failures/16 control passes;
unit and browser regressions reproduced false overlap. CI reached the
new unit assertion.
- GREEN: all 48 packet cases pass, plus grouped-cache isolation and
OpenAPI tests. The added cache regression caught a malformed-radio
cache-key collision before correction.
- Full local server suite: 174s; ingestor: 185s; `npm run test:unit`:
pass. Final focused packet/grouped/OpenAPI checks: pass.
- E2E assertion added to
`tests/e2e/test-issue-1640-compare-discovery-e2e.js`; all 10 checks
pass, including correct 1/2 reception totals and 50% overlap.

Performance: still two capped bulk requests, indexed candidate lookups
retained, one direction check within the existing observation scan/SQL
predicate, no new persistent structures. No configuration/customizer
changes.

Final-head CI passed; independent reviews found no must-fix items.

n30nexandn30nex c211ef7643 feat(nodes): show relay activity from certain forwarding evidence (#2336)
Fixes #2331 with the additive API option.

The Last Relayed row shows green **actively relaying** only when
`last_certain_relay` falls within the existing
`healthThresholds.relayActiveHours` window. Missing, invalid, future or
expired evidence adds no idle/alive claim. Existing `relay_active`,
attributed timestamps and counts retain their meanings.

The optional node list/detail field uses the existing certain-relay
path: an eligible observed frame, matching hop, unique prefix, no
retired namesake and existing signature checks. Originating an advert
does not count. Forwarding another node's advert can count, even with
zero non-advert attributions. Adverts with an unknown origin cannot
establish forwarding.

Evidence uses transmission `first_seen`, not late observation receipt
time, and follows node-membership eviction. Snapshots take one read lock
over requested keys, O(page size), with no packet scan or new database
query. Work per qualifying hop stays bounded. No new dependency or
setting; configuration documentation and OpenAPI explain the
distinction.

The test-first history includes assertion-failing RED commits and GREEN
fixes. The initial RED's nil-return compile stub is explicitly permitted
by `docs/agents/TDD.md`. Local native server/ingestor suites, focused
race checks, 809 frontend helper assertions and 70 browser cases pass.
Browser coverage includes both themes and full/side/tablet detail views.

n30nex 1e1bfa0255 fix(ingestor): require unique hop prefixes for relay liveness (#2334)
Fixes #2329 (option 1: unique-prefix liveness).

The ingestor could select a likely relay through neighbour adjacency and
refresh its `last_seen` even when its prefix matched two nodes.
Contextual resolution remains available in stored `resolved_path`;
liveness now uses the existing unique-prefix resolver, sharing the
parsed path and prefix-index snapshot. The current flood-frame
eligibility gate remains unchanged. Retired-prefix catalogue parity with
the server is separate.

The native SQLite regression exercises real `InsertTransmission`: the
displayed path still selects the adjacent candidate, neither colliding
relay is touched, and the unique preceding hop is refreshed. Existing
direct/TRACE/flood checks remain intact. [RED

Full local server and ingestor suites, repeated focused race checks and
all 221 frontend suites pass. Existing test assertions are unchanged;
one misleading resolver comment is corrected. Frame/path assumptions
were checked against MeshCore firmware revision `81dbae59`.

Performance: one additional indexed lookup per hop, O(h), with no node
scan or extra database query. No schema, dependency, configuration or
customizer change. [Final

n30nex f9b7c66a8b fix(ingestor): open buffered writes before startup packet retention (#2328)
Partial fix for #2325; leave the issue open for the remaining startup
work.

MQTT subscribed early but its buffer could not drain until the entire
packet-retention backlog finished. Required startup work and the
migration barrier still finish first; ingestion now opens before the
initial packet sweep, so buffered writes can use the gaps between the
existing 250-transmission transactions.

The sweep remains synchronous with its count/error logging. No new
worker, shutdown owner, setting, retention window or batch size. The
readiness log reflects the actual gate opening. Earlier non-packet
maintenance, initial vacuum ordering and diagnostics publication during
maintenance remain unchanged.

Native SQLite tests exercise blocked migrations, inter-batch writes,
FIFO/drop accounting, stopped buffers, callback counts, rollback/retry
and main-function wiring. Removing the migration wait fails the
regression. Existing tests are unchanged; GREEN strengthens the new RED
test with a blocked-gate assertion and early-failure cleanup.

[RED
CI](https://github.com/Kpa-clawbot/CoreScope/actions/runs/40308382930)
fails the intended assertions. [Final-head
CI](https://github.com/Kpa-clawbot/CoreScope/actions/runs/40311222867)

shards and architecture builds. Full local ingestor tests, repeated
focused race checks and local browser/API smoke checks pass. Three
independent reviews found no blockers in this partial scope.

This removes the whole-sweep startup gate; it does not bound an
individual deletion transaction or claim a measured live latency
improvement.

n30nexandn30nex ef17d78909 docs(api): document node resolution and battery history (#2338)
Partial follow-up to #1670; the broader documentation issue stays open.

Documents the existing node-prefix resolution and node battery-history
GET APIs: parameters, normalization and lookup rules, defaults,
ambiguity/visibility, ordered samples, nullable latest values and error
media types. The generator now has concrete success schemas for both.
Error statuses remain documented in prose under its existing convention.

Removes exactly these two entries from the known-gap list: 18 → 16, with
115 of 131 routes described. No handler, query, configuration or
dependency changes.

both full native CGO suites and focused OpenAPI/real-handler contract
tests. Parent browser acceptance passed 28 checks through the rendered

empty/null history.

All three independent review roles passed. [Final

n30nexandn30nex 8437d22356 docs: use consistent snapshots for backup and restore (#2345)
The deployment guide copied a running `meshcore.db`, which can omit
committed WAL data or produce an inconsistent backup. It now uses the
existing authenticated `/api/backup` snapshot, checks the download
before publishing it, and explains how to restore with all database
users stopped while preserving the old database and sidecars for
rollback.

Fixes #703, following the [maintainer's remaining documentation
scope](https://github.com/Kpa-clawbot/CoreScope/issues/703#issuecomment-6163256620).

- Protects API credentials in a header file and keeps incomplete
downloads out of the completed backup set.
- Links the separate account-backup guide; configuration and secrets
remain separate backup responsibilities.
- Replaces unsafe live-copy scheduling instructions with the same
checked download procedure.

Validation:
- Exact shell example with real curl/SQLite: valid download, HTTP
401/500, empty, HTML, corrupt database, and truncated transfer. Failures
preserved the previous backup and published no new `.db`.
- Existing `TestBackup*` passed. Chromium downloaded an authenticated
snapshot from a disposable instance; a row committed only in its
nonempty WAL survived and `quick_check` returned `ok`.
- Disposable stopped-file restore and rollback recovered the original
WAL-only row and preserved the original files byte-for-byte.
- `git diff --check` and privacy preflight passed.

TDD exemption: pure docs; no application behavior changed and no test
files modified. No new config/customizer settings. Live operator
services were not used for validation.

efitenandClaude Opus 5.5 15e2d2a4a7 fix(packets): read HB from the row's own raw_hex header (#2351)
## Problem

The HB column on the packets page can show `4`. Path mode 3 (hash size
4) is reserved: `Packet::isValidPathLen` in `src/Packet.cpp` returns
false for it, and `Dispatcher::checkRecv` drops such a packet. So HB 4
is never a real value.

The three HB cells in `public/packets.js` found `path_len` with
`getPathLenOffset(p.route_type)`, the route type of the
**transmission**. The raw_hex in a child row (and in a live-updated row)
is an **observation's** raw_hex. The packet hash does not cover the
route bits, so the same packet is heard as FLOOD by one observer and as
TRANSPORT_FLOOD by another, and the transmission keeps the route type of
its first observation.

Example from a production DB (transmission 3645334):

| source | raw_hex start | path_len at |
|---|---|---|
| transmission | `01 12 3A646A…` (FLOOD) | byte 1 |
| observation | `00 E2E0 0000 1D 3A646A…` (TRANSPORT_FLOOD) | byte 5 |

Read at the FLOOD offset, the observation gives `0xE2`, `0xE2 >> 6 = 3`,
`+ 1 = 4`. In the last 300,000 observations of that DB, about 4,300 have
a header route type that differs from their transmission's.

## Fix

`pathHashSize(rawHex)` in `public/app.js` already takes the route type
from the header byte of the same raw_hex, and the detail pane uses it.
The three HB cells now call it through a small `hashBytesText` helper
instead of carrying their own copy of the offset logic.

Behaviour change: a raw_hex with no hash size (reserved mode 3, a DIRECT
packet with no hops, missing raw_hex) shows the same placeholder as
TRACE rows instead of a number. Before, missing raw_hex showed `1`.

## Tests

- New `tests/unit/test-hb-column-header-route.js` (7 cases, registered
in `test-all.sh`): transport raw_hex on a FLOOD transmission gives 1,
flood raw_hex with 2-byte hashes on a TRANSPORT_FLOOD transmission gives
2, reserved mode 3 never gives 4, for the helper, the flat row and the
group header. It fails on `upstream/master` with `'4' !== '1'`.
- `sh test-all.sh`: all standalone frontend suites pass.
- Browser: local server on a migrated copy of the E2E fixture, with one
observation rewritten to a TRANSPORT_FLOOD raw_hex. The expanded group
shows HB 2 on all three rows. The old code reads `0xE2` on that child
and shows 4.

## Performance

Same per-cell work as before: one header parse and one byte parse per
rendered row, O(1), no new allocations beyond the existing regex test in
`pathHashSize`. Only visible rows are rendered.

## Not done

- The child-row call site is not hit by a unit test: child rows only
render when the group is in `expandedHashes`, which the test API does
not expose. It is covered by the helper test and the browser check
above.
- The HB sort accessor (`hash_byte_count` / `hash_size`, sort key `hb`
in `packets.js`) is unchanged; it does not read raw_hex.
- `transportBadge(c.route_type)` on child rows still follows the stored
route type, not the observation header. Left out of scope.

efitenandClaude Opus 5.5 b65412ab83 feat(observer-logins): turn on neighbour reports in the firmware block of the credentials mail (#2349)
The firmware block of the observer credentials mail now ends with `set
mqtt.neighbors on`, so firmware observers send the same `/neighbors`
report that the OpenHop block already turns on ("Publish Neighbours",
#2347). The ingestor reads that report for region scopes (#1865).

## Changes

- `cmd/server/observer_mail.go`: one extra line in the firmware block,
and one sentence in its note. The sentence says the command sends the
neighbour table and region scopes once a day, and that older firmware
does not know it and should skip it.
- `cmd/server/observer_mail_test.go`: the full firmware block assertion
includes the new line, and the slot test checks the line and the note.
- `docs/observer-mqtt-logins.md`: the mail section describes the new
line.

## Tests

- `go test ./...` in `cmd/server`: ok. Skipped
`TestSaveGeoFilterPreservesFileMode`, which needs Unix file modes; this
run was on Windows.
- `TestObserverCredentialsMail*` failed before the change, on the
missing line, and passes after it.

## Not checked

- The command name and the 24-hour default come from #1865. I did not
read the observer firmware source.
- The wording of the error older firmware gives for an unknown command
is not quoted in the mail. The note only says to skip the line.

efitenandClaude Opus 5.5 ddce76a685 ci(e2e): run the E2E shards on ubuntu-24.04 and fail on a broken browser install (#2350)
`ubuntu-latest` now hands out `ubuntu-26.04` runners. Every E2E shard
that lands on one fails before a single test runs:

```
browserType.launch: Executable doesn't exist at /home/runner/.cache/ms-playwright/chromium_headless_shell-1208/...
```

The step "Install Playwright browser" runs `npx playwright install
chromium 2>/dev/null || true`, so its own failure is invisible and the
job only breaks at the first browser launch.

## Evidence

- Run 40779894898 (PR #2349, a mail-text change): three attempts, each
failing on `Executable doesn't exist`. The job log shows `Image:
ubuntu-26.04`, OS `26.04.1 LTS`.
- The master run at 2026-10-28 21:31Z passed. Its shard log shows
`Image: ubuntu-24.04`.
- `playwright` in package-lock.json is 1.58.2.

## Change

- `e2e-shard` gets `runs-on: ubuntu-24.04`, with a comment saying when
to unpin. The other jobs do not install Playwright and stay on
`ubuntu-latest`.
- "Install Playwright browser" no longer has `2>/dev/null || true`, so a
failed install fails at that step.

## Not done

- I did not find out why the install fails on 26.04: its stderr was
discarded. Once this is merged, a run with the pin removed would show
it.
- No Playwright upgrade. That is a separate change, and it may make the
pin unnecessary.
- Before this change, `install-deps` errors were also swallowed. If it
fails on 24.04, this PR's own CI will show it.

efitenandClaude Opus 5.5 cadc666bd9 feat(observer-logins): OpenHop block in the credentials mail (#2347)
The observer credentials mail (#2306) had blocks for meshcoretomqtt, the
Gessaman/Dutch-MeshCore firmware, Home Assistant and plain values. An
operator running OpenHop (repeater software with its own MQTT uploader)
could not tell which of these matched its broker form, and picked the
format by trial.

## Changes

- `cmd/server/observer_mail.go`: a fifth block, "4. OpenHop (repeater
software)", before the plain values. It uses the field and option labels
of the OpenHop broker form:
- `Format: Letsmesh`, `Transport: TCP` or `Websockets` (from
`observerLogins.transport`), host, port, username, password, `TLS:
on/off`, `Use JWT Auth: off`, `Retain Status: on`, `Publish Neighbours:
on`.
- The note says Meshcoretomqtt works too, but the format labelled
"openHop" (value `mqtt`) does not: it publishes to
`meshcore/repeater/<name>`, which a personal login may not use.
- Publish Neighbours is on because the ingestor reads the `neighbors`
topic for region scopes (#1865).
- `openapi.go` and `docs/observer-mqtt-logins.md`: "four formats"
becomes five.

## Sources

Read from OpenHop, not tested on a device by me:
- format family and topics:
`openhop_repeater/repeater/data_acquisition/mqtt_handler.py`
(`MC2MQTT_FORMATS = ("meshcoretomqtt", "letsmesh", "waev")`, the `mqtt`
format's `meshcore/repeater/<node_name>` base topic, transport values
`tcp`/`websockets`);
- labels: the built web UI (`Configuration-*.js`: "Add Broker", option
labels `Letsmesh`, `Meshcoretomqtt`, `openHop`, `TCP`, `Websockets`,
"Retain Status", "Publish Neighbours", "Use JWT Auth").

An operator on our instance set it up from a screenshot of that form
with format Letsmesh, TCP, Retain Status and Publish Neighbours on; the
observer publishes, and its `neighbors` report set `configured_scope` on
its node.

## Tests

- `TestObserverCredentialsMailOpenHopBlock`: the block text for TCP
without TLS and for Websockets with TLS, the "openHop" warning, HTML
escaping, and the block order.
- `TestObserverCredentialsMailBlockTitles`: five titles in order.
- `cmd/server` suite green locally (the two Windows-only failures
skipped, as on master).

## Not in this PR

- The websocket path: OpenHop uses paho's default, the doc already tells
operators to match the listener path.
- Anything with the other fields of the `neighbors` report (SNR,
heard_secs_ago, default_scope): we are measuring how many observers send
it first.

n30nex 3bf678709f fix(ui): preserve navigation and menu focus during delayed updates (#2333)
Fixes #2332. Fixes #2335.

Two delayed UI updates could undo user actions. Rebuilding the More menu
removed its focused link; a late packet-list response could replace a
newly requested Nodes URL before `hashchange` ran.

The menu now preserves the selected destination when it stays in More or
moves inline, closes an empty menu, and leaves other controls' focus
alone. Packet URL updates now require the packets route, including its
existing detail/query forms. Observation selection and encoded filters
remain supported.

The changes add one lookup across the existing 12 navigation links and a
URL ownership check. No packet loop, API request, dependency, setting or
customizer change is added.

[Packet
RED](https://github.com/Kpa-clawbot/CoreScope/actions/runs/40409110743/job/121874676123)
fails four wrong-route assertions. [Menu
RED](https://github.com/Kpa-clawbot/CoreScope/actions/runs/40409898375/job/121877663579)
fails the intended focused-destination assertion after the packet
correction removes the competing navigation failure. GREEN is
`57522143`.

Local combined validation passes all 221 standalone frontend suites, 60
navigation browser checks, 17 branding/route checks and 11
filter/deep-link checks. The packet regression controls delivery of a
real API response; substituting the original code still fails it.
Existing exact title assertions remain; diagnostics now report the
actual title. Backend source trees are unchanged from the tested
baseline.

[Final
CI](https://github.com/Kpa-clawbot/CoreScope/actions/runs/40410894023)
passes on `57522143`, including all three browser shards and both
architecture builds. Three independent source reviews found no blockers.
Final repository checks and after-push browser verification pass. Ready

Follow-up to #2306 / #2319. With personal observer logins, a migrated
observer still is not safe from the shared login: the hook answers
`ignore` for the shared login, so EMQX's built-in database lets it
publish under any observer's topic, including one whose owner has moved
to a personal login. This PR lets an operator close that per migrated
observer, before the shared login is removed altogether.

## Changes

**users.db v8.** `observer_bindings.confirmed_at`: the moment the
owner's personal login first published under that pubkey.
- An auto-bind (the owner's first publish) is confirmed at once.
- An admin assignment stays unconfirmed until the owner's login
publishes under that pubkey; that publish sets it.
- Reassigning to another user or unbinding clears it; reassigning to the
same owner keeps it.
- Migration: existing `auto` rows get `confirmed_at = bound_at`, `admin`
rows stay NULL.

**Config.** `userManagement.observerLogins.sharedUsernames` (default
empty): the broker's shared login names. A name starting with `obs_` is
refused at startup.

**Authz hook.** For a login in `sharedUsernames`, a publish under
`meshcore/<x>/<pubkey>/...` is denied when that pubkey's binding is
confirmed, whatever the number of topic segments (the ingestor
attributes `meshcore/<x>/<pubkey>` and longer topics to that pubkey).
Logged as `publish denied: user=<name> observer=<8 hex>: confirmed
owner`. Every other request from a shared login keeps `ignore`, so the
built-in database decides as before. Personal logins are unchanged.

An orphaned binding (owner account deleted) does not count as confirmed.

**Admin.** The observers table of the Observer logins tab gets a
Confirmed column; the bindings JSON gets `confirmedAt`.

**Docs.** `docs/observer-mqtt-logins.md`: "Locking the shared login out
of migrated observers" (what it denies, how to see `confirmedAt`, the
risk below). `config.example.json` has the key.

## Risk for operators

An observer that is confirmed but still runs a second uploader on the
shared login loses that second uploader once its name is in
`sharedUsernames`. The deny log line names the observer.

## Tests

- `internal/users`: v7 to v8 migration on a real v7 database, auto
confirm, admin assignment then owner confirm, non-owner and repeated
confirm, reassign clears, orphan reassign.
- `cmd/server`: the decision table (confirmed, unconfirmed, unbound,
non-publish), topics with 3, 4 and 5+ segments, trailing slash, empty
and `client` iata, lowercase key; owner publish confirms, confirm
failure still allows and retries; reassign, unbind and user removal
clear the flag; the index load against a real store; config validation;
the hook and admin endpoints end to end.
- `tests/e2e/test-user-management-e2e.js`: the Confirmed column for an
auto-bound observer.
- Local: `internal/users`, `cmd/server` (two Windows-only tests skipped,
as on master) and `cmd/ingestor` green. The E2E assertion was not run
locally; CI runs it.

## Not in this PR

- Using `confirmed_at` for verified `/neighbors` reports: a separate PR,
built on #2300.
- Removing the shared login: still an operator step after migration.

TeTeHackoandClaude Opus 5.5 660cbbf5ff deps: golang.org/x/net v0.61.0, x/crypto v0.58.0, paho.mqtt.golang v1.5.1; runtime alpine:3.24 (#2297)
A Trivy scan of the published image found **19 HIGH and 20 MEDIUM** in
Go dependencies, plus a runtime base past its support window. There is
no Dependabot here, so this collects the bumps in one PR.

| dependency | from | to | why |
|---|---|---|---|
| `golang.org/x/net` (ingestor) | v0.27.0 | v0.61.0 | CVE-2024-45338 and
later advisories, fixed up to v0.60.0 |
| `golang.org/x/crypto` (server, `internal/users`) | v0.31.0 | v0.58.0 |
CVE-2025-22869, CVE-2025-47913 and later; `x/sys` follows to v0.49.0 |
| `github.com/eclipse/paho.mqtt.golang` | v1.5.0 | v1.5.1 |
CVE-2025-10543, an integer overflow in the UTF-8 string encoding |
| runtime image | `alpine:3.20` | `alpine:3.24` | 3.20 is out of
support; its musl 1.2.5-r3 carries CVE-2026-107891 |

The Alpine change covers `Dockerfile`, `Dockerfile.go`, the arm64 smoke
step in `deploy.yml` and the comment in
`docker/test-select-service-user.sh`.

**What changes besides the versions:**

- The new `x/` modules declare `go 1.26.0`, so the `go` directive of
`cmd/server`, `cmd/ingestor` and `internal/users` moves up from 1.22.
The builder image and CI already run 1.27.
- `x/sync` follows paho to v0.17.0.

**What is left:** only `GO-2026-5932`. It flags `x/crypto/openpgp` as
unmaintained; nothing here imports that package and no fix exists.

## Checks

- Every module passes `go mod tidy`, `go build` and `go vet`.
- `go test -race` passes in `internal/users`, `cmd/ingestor` and
`cmd/server`.
- A local image build on alpine 3.24.3:
  - ships mosquitto 2.1.2, caddy v2.11.4 and supervisor 4.3.0
- keeps the caddy and mosquitto accounts at the same uid:gid (100:101,
101:102), so `test-select-service-user.sh` still describes the image
(116 assertions pass)
- comes up healthy, ingests an MQTT status through mosquitto and serves
the frontend

TeTeHackoandClaude Opus 5.5 77a5f14925 feat(observers): radio setting per observation from the observer's radio history (#1869) (#2292)
Part of #1869.

## Problem

`observers.radio` keeps only the **last** `MHz,kHz,SF,CR` an observer
reported. Once an observer is retuned (say from SF7 to the EU narrow SF8
setting to listen to a neighbouring mesh), every packet it ever heard
reads as heard on the new setting, and there is no way to tell an SF7
packet from an SF8 one.

## What this does

As #1869 proposes, the packet data model is untouched: the setting of an
observation is resolved from its observer and time.

**Ingestor** (all schema in `dbschema.Apply`)

- `observer_radios`: one row per stretch of time an observer, and each
radio of a multi-radio node, stayed on one setting. Every live status
extends the current row and a change starts a new one; retained replays
never extend a row. On the first run it is seeded with every observer's
current radio, which is what the UI already showed for the past.
- Settings are stored canonical through `dbschema.CanonicalRadio`, so
`869.4320068,62.5,7,5` and `869.432,62.50,7,5` are one setting.
- `observation_radios` (`observation_id → rx_radio_id`): multi-radio
openHop nodes tag each packet with `rx_radio_id` and list `radios: [{id,
radio}]` in their status, so their observations resolve per radio.
- The table is sparse: single-radio nodes never send the field, so
`observations` and every query that scans it stay untouched.
  - The row id comes from the observation upsert via `RETURNING id`.
- Rows are pruned with their transmissions, and a purged observer takes
its history along.

**Server** (read-only)

- No `AssertReady` change: an absent table reads as empty and is probed
again later, the same rule as `advert_route_evidence`.
- The history is held in memory. The live poller checks it on every tick
(two primary-key lookups), so a retune or a new `rx_radio_id` is known
before the observation is broadcast. A full reload runs every 10 min.
- `radio` is added to observations, packets, grouped rows (taken from
the header observation) and the live feed.
- `GET /api/packets?radio=MHz,kHz,SF,CR` filters by setting.
- Combined with `observer=`, it means *that* observer heard it on that
setting.
- A radio query is served from memory instead of falling back to SQL,
which would return the window unfiltered.
- `GET /api/radios` (named struct) and `radio_history` on `GET
/api/observers/{id}`.

**Frontend**

- Packet filter fields `radio`, `freq`, `bw`, `sf`, `cr`, e.g. `sf == 8`
or `freq > 869.5 && bw == 62.5`.
- A Radio row in the packet detail and a Radio column in its
observations table (only when the server reports one).
- A radio history table on the observer page once there is more than one
stretch.
- `RfParams.radioText` formats the setting. It escapes all five
characters and returns non-numeric input as it came, escaped.

## Performance

`txMatchesRadio` runs once per observation inside `filterPackets`.

- Each observation costs one map lookup by observer id.
- Observers with a single stretch (nearly all) answer from that lookup
directly.
- Retuned observers add a binary search over their few stretches.
- Multi-radio observers add one lookup by observation id.
- The snapshot is loaded once per filter call.

`BenchmarkTxMatchesRadio`, 30K packets / 150K observations (20
observers, 2 of them retuned):

```
BenchmarkTxMatchesRadio-24    602    2056924 ns/op    0 B/op    0 allocs/op
```

Memory is one entry per stretch plus one per multi-radio observation;
nothing is added per observation otherwise.

## Tests

- **dbschema:** seed runs once, canonical spellings, the tables exist
without `observers.radio`.
- **ingestor:**
  - stretches extend and split; canonical spellings do not split
- two radios of one node hearing one transmission over two paths each
keep their own radio
  - a retained status does not write history
  - prune and purge
  - `rx_radio_id` reaches `PacketData`
- **server:**
- resolution before, between and after stretches, and with an unknown
radio id
  - `observer` + `radio`, and grouped rows carry `radio`
  - incremental refresh, `/api/radios`, `radio_history`, missing tables
  - the benchmark above
- **frontend:** the new filter fields in
`tests/unit/test-packet-filter.js`, and XSS cases through the real
`RfParams.radioText` and the history renderer.
- **E2E:** `tests/e2e/test-radio-setting-1869-e2e.js` checks the grouped
rows' radio, `sf ==` on the packets page, the detail Radio row and the
observer history. It is added to `scripts/non-unit-tests.json` and to
shard 2.

`go test -race` in `cmd/server`, `cmd/ingestor` and `internal/dbschema`
passes, along with `sh test-all.sh`, `eslint@8` (0 errors) and the XSS
diff gate. The new E2E test and `test-e2e-playwright.js` pass against
the fixture.

## Browser validation

This runs on a live instance with six observers, one of them retuned to
869.618/62.5/SF8/CR8:

- The packet detail shows `Radio: 869.432 MHz · SF7 · BW 62.5 kHz · CR
4/5`.
- `sf == 7` shows 106 of 106 grouped rows and `sf == 8` shows 0 of 107;
the SF8 observer has not heard anything yet.
- `/api/radios` lists both settings.
- No page errors.

## Notes

- **The customizer (rule 8)** gets nothing: the only constants are
server-side refresh intervals.
- **Attribution timing:** packets heard between a retune and the
observer's next status message (minutes) are attributed to the previous
setting, because a stretch starts when the status is handled. This is
documented at `RecordObserverRadios`.

Red commit: `7277ca23` ([failing
CI](https://github.com/Kpa-clawbot/CoreScope/actions/runs/40190626951)).

Fixes #2229. Management startup now defines logging helpers before
normalizing CRLF environment files. Updates refresh version, revision
and build time after checking out the target. Deployment verification
and all five Compose healthchecks use `/api/healthz`, so an available
statistics endpoint cannot report an unfinished startup as healthy.

- The actual-script regression passes 15 checks: LF/CRLF/no environment
file, repeat startup, all update targets, failed checkout,
delayed/failed readiness, HTTPS readiness and unchanged informational
statistics.
- RED CI reproduced all 11 intended failures; GREEN `7ff9050b` passes
the full standalone frontend suite and shell syntax checks.
- Browser verified: an isolated Go fixture at http://127.0.0.1:18851

Fixes #2232. Battery badges now render their fixed status icon and
append voltage as text, including zero. Chart sizing excludes inline
icons, and status colors use the existing theme variables. Unknown
status values stay muted.

- The original browser regression failed on literal SVG; a second local

n30nex d07186af43 fix(nodes): preserve names and metadata in preview panels (#2315)
Fixes #2309 and #2312. Partial follow-up to #1154 (U1 and tablet
timestamp parity).

Node previews omitted Last Relayed, Traffic share and Hash Prefix, while
tablet previews read `advert_name` instead of the API's `name`. Shared
rendering now presents those fields consistently across full detail,
side preview and tablet, with the existing timestamp tooltips.

Relay attribution is labelled neutrally: ambiguous relay evidence no
longer claims a node is alive. Existing certainty/status logic is
unchanged. Measured zero, legacy score fallback, role applicability,
missing values and escaped names/hash tooltips are covered. A resize
regression prevents duplicate score-row IDs across retained desktop and
tablet previews.

Only the selected node's metadata is formatted. Existing request counts
remain five for full/side and two for tablet; no new fetch, cache, hot
loop, setting, customizer value or dependency.

Validation: 806 helper checks, all 218 standalone suites, 46 browser
checks in both themes, eight health checks, and the main browser suite
(149 passes, three existing fixture skips). The unchanged backend tree
passed full server/ingestor suites. Independent reviews completed; the
parent verified the two-line follow-up from its resize check.

Test-only RED `e0f681ae` produced [eight expected assertion

Fixes #2291; addresses U7 of #1154. The two observed-path links now say

sample-packet destination. Recent-advert labels and link behavior remain
unchanged.

- Production diff: two text literals in public/nodes.js.
- Existing browser suite preserves contrast/highlighting assertions and
adds exact labels, canonical destinations and real click-through from

Red commit: `e5589b4c` ([failing
CI](https://github.com/Kpa-clawbot/CoreScope/actions/runs/40191348162)).

Fixes #2216. Navigation measures the available flex strip instead of
guessing component widths. Optional statistics and spacing yield when
primary/active links would overlap More. Account insertion triggers a
layout event immediately, including while authentication is pending or
fails; normal user-change events retain their semantics.

- Regression CI reproduced link overlap across narrow widths and late
account controls. Review added a second RED test for the actual delayed
authentication bootstrap before the three-line correction.
- Validation on `f0ccbf4c`: full frontend suite; 89 user-management
checks; 56 navigation checks; existing priority and clipping suites.
Parent independently reran auth and browser checks.
- Browser verified: http://127.0.0.1:18854; real bootstrap overlap of
14.66px becomes 21.38px clearance. Resizing, account changes, keyboard
More and touch targets remain covered.
- E2E assertion added: `tests/e2e/test-nav-fluid-1055-e2e.js:89`.
- Work is bounded by the fixed navigation link set; events share one
animation frame. No polling, observers, new requests, dependencies or

Red commit: `a62753de` ([failing

Fixes #2259. Browser titles now identify the current page, Analytics

Reach view reads `Node abababababab | Reach | CoreScope`. Detail
identifiers are limited to 12 characters; account/reset parameters stay
out of titles.

- Branding and page context have separate state, so delayed theme loads
and edits cannot erase the view or accumulate suffixes. Selection/close
paths that use replaceState also update the title.
- Validation: all standalone frontend suites; 29 focused unit checks; 16
browser steps covering routes, history, reload, tabs, real row clicks,
closing, branding and literal route text. An explicit All time selection
keeps the browser test independent of fixture age.
- Browser verified: http://127.0.0.1:18853 on an isolated Go fixture.
- E2E assertion added: `tests/e2e/test-customize-branding-e2e.js:48`.
- Fixed-size work at navigation/selection boundaries; no extra requests,
DOM observers, render-loop work, dependencies or settings.

TeTeHackoandClaude Opus 5.5 684f89f200 feat(frontend): serve Leaflet, leaflet.heat and Chart.js from vendor/, not unpkg.com (#2299)
Refs #1554.

`index.html`, `area-map.html` and `geofilter-builder.html` load Leaflet,
leaflet.heat and Chart.js from **unpkg.com** on every page view. That
causes three problems:

- **Privacy:** every visitor sends a request to a third party.
- **Availability:** where unpkg is blocked (script blockers, filtered
networks) or down, the map and every chart are gone. The observer page
then fails with `Error: Chart is not defined`.
- **#1554:** the CSP target there, `script-src 'self'`, blocks these
scripts just like the inline handlers the issue lists, but they are
missing from its inventory.

## Change

- **Vendored libraries:** `public/vendor/leaflet-1.9.4/` (with
`images/`), `vendor/leaflet-heat-0.2.0.js` and
`vendor/chart-4.5.1.umd.min.js`.
- They are the unpkg dist files byte for byte, verified against the SRI
hashes `index.html` already pins.
- The two standalone pages loaded Leaflet without SRI; they now carry
it.
  - This is the same pattern as `vendor/leaflet.markercluster.js`.
- **`.gitattributes`:** `public/vendor/** -text`. Otherwise `* text=auto
eol=lf` rewrites `leaflet.css`, which ships with CRLF, and the browser
refuses it for the integrity mismatch. I hit exactly that while
preparing this.
- **`scripts/instrument-frontend.sh`:** now copies `vendor/`
recursively. The flat `cp public/vendor/*` left the E2E server without
`vendor/leaflet-1.9.4/`, which showed up as `L is not defined`.
- **New test `tests/unit/test-vendored-libs.js`:**
  - no off-site `<script src>` or stylesheet in the served pages
  - every `integrity` attribute matches its vendored file
  - the images Leaflet's stylesheet references exist

  I checked that it fails against the old `index.html`.

## Checks

- `sh test-all.sh` passes.
- These E2E suites pass against the fixture: `test-e2e-playwright.js`,
`test-analytics-fluid-charts.js`, `test-issue-1236-map-mobile-e2e.js`
and `test-issue-1329-map-controls-accordion-e2e.js`.
- On a live instance, a headless browser with `unpkg.com`, `jsdelivr`
and `cdnjs` blocked:
  - the observer page renders all four charts
  - the map loads tiles and markers
  - `typeof L` and `typeof Chart` are defined
  - no CDN request is made and no page error occurs

## Not in this PR

Swagger UI on `/api/docs` (`cmd/server/openapi.go`) still loads
`swagger-ui-dist` from unpkg. I can vendor it in a follow-up if wanted.

n30nex e61ff6e473 fix(observers): keep detail responses tied to the current view (#2323)
Fixes #2316 and #2320. Related to #1778; progressive loading remains
separate.

Delayed observer responses could replace a newer observer or period,
overwrite its error/status/calibration, and leave detached charts alive.
Each load now captures its observer and days and checks ownership before
success or failure can update the view. Leaving the page invalidates
pending loads, including same-observer revisits.

New visits also reset the request window to the selector's existing
seven-day default. Previously, a new page could display seven days while
requesting the preceding visit's 30-day window.

Production change: 12 added lines and three replacements in one frontend
file. No new requests, caches, settings or dependencies; the ownership
check is O(1). Existing request deduplication, comparison controls,
chart cleanup and current-request errors are preserved.

Validation: 11 unit checks, all 219 standalone suites, 32 controlled
browser cases across desktop/mobile and both themes, comparison 9/9, and
observer-IATA 5/5. Core browser run exited successfully with 149 passes
and three declared fixture skips; existing conditional subchecks remain.

n30nex 1dfcd0f5d3 fix(analytics): preserve distance invalidation during an active build (#2284)
Red commit: `38c0abe1` ([failing
CI](https://github.com/Kpa-clawbot/CoreScope/actions/runs/40190273036)).

Fixes #2281. Background-fill completion could reset an active
`sync.Once`, causing a fatal mutex unlock or letting an older distance
build mark an incomplete index ready. Build admission now uses the
existing mutex, and a generation check prevents stale completion from
consuming invalidation. The loader also releases the store lock before
acquiring the distance gate.

- Deterministic regression drives the actual loader, recomputer and HTTP
handler; the old runtime crash is contained in a child process.
- Two cold observations stay below the normal 5% rebuild threshold. Ten

n30nex f66cd320da perf(graph): reuse indexed shortest-path workspaces (#2293)
Red commit: `8b3cffd0` ([regression
CI](https://github.com/Kpa-clawbot/CoreScope/actions/runs/40203043161)).

Fixes #2226. Bridge and coverage scoring now convert keys once and reuse
indexed distance/predecessor workspaces and at most one heap item per
vertex. Existing algorithms, normalization, snapshot publication and
synchronous startup behavior remain intact.

Five paired runs, deterministic 2,000-node/10,000-edge fixture, Go
1.27.2 on Windows/amd64, GOMAXPROCS=2:

| Calculation | Median time | Allocated bytes/run |
|---|---:|---:|
| Bridge | 8.237s → 0.819s | 2,083,295,328 → 2,517,664 |
| Coverage | 4.900s → 0.694s | 1,508,440,736 → 2,209,984 |

The desktop was shared; baseline bridge runs ranged 7.81–17.56s. These
are algorithm/allocation measurements, not startup/API latency or
retained memory. Rebuilding committed `5f34b5bf` produced the exact
measured binary hash.

- Independent path oracle, edge/epsilon/tie/disconnected cases,
allocation regression, race checks and full server/frontend suites pass.
- Browser verified: isolated native servers at http://127.0.0.1:18903
and http://127.0.0.1:18904 return identical nonzero graph scores.
- O(V+E) bounded workspace; O(V(V+E) log V) calculation. No persistent
cache, schema, dependency or configuration change.

Independent reviews and local preflight checks passed. External
home-directory preflight bundle unavailable; applicable checks were
performed locally. [Final

n30nex 63d63ea90a perf(healthz): avoid scanning retained packets after startup (#2305)
Fixes #2301.

Readiness probes currently scan every retained transmission while
holding the packet-store read lock. Once `StartupLoadDone` closes, this
reads the maintained observation counter beside the transmission count
under that same lock. Count extraction becomes O(1), with no new cache,
query or allocation.

Startup retains the original scan: the background loader publishes
indexes before its packet slice, so switching on readiness or
`LoadComplete` would be premature. Response fields, readiness status,
ingestion and configuration remain unchanged.

Whole-handler benchmark medians, microseconds per probe:

| Retained transmissions | Upstream | Candidate |
| ---: | ---: | ---: |
| 1,000 | 72.14 | 83.84 |
| 30,000 | 320.85 | 65.74 |
| 100,000 | 1,228.50 | 81.97 |

Four alternating pairs, 10,000 iterations/size, real SQLite-loaded
fixtures with three observations per transmission on average; Go 1.27.2,
Windows/amd64, two CPUs. All samples retained; shared-host variability
means no small-cache or production-latency improvement is claimed.
Allocations remain 36/probe. The included benchmark supports
reproduction against unchanged upstream production plus the identical
harness.

TDD exemption: pure performance refactor; **all pre-existing test files
are byte-unchanged**. Added characterization tests pass before and
after, covering loaders, deduplication, live updates, eviction, partial
startup failures, concurrent snapshots and liveness. Independent review
prompted test-only follow-up `2a0083b1`, which detects premature counter
use; production remains identical to measured `1b8e6680`.

Full server, race, ingestor and post-push browser/API checks pass
locally. [Final-head CI

including all browser shards and architecture builds. No customizer

n30nex abad8a26b3 fix(liveness): require evidence from each observed relay frame (#2298)
Red commit: `46e3b082` ([regression
CI](https://github.com/Kpa-clawbot/CoreScope/actions/runs/40203680455)).

Fixes #2266 and #2267. Certain relay activity now requires an eligible
path from the observation that supplied it. A representative
transmission header, destination attribution or catalogue uniqueness
alone cannot supply that evidence. Later valid FLOOD evidence survives
observer/path deduplication.

The fix preserves valid own packets and excludes failed signatures,
planned DIRECT/TRACE paths, ambiguous/retired prefixes and missing or
mismatched headers. Firmware reference: meshcore-dev/MeshCore
`81dbae59`.

- One eligibility byte replaces an unused raw-frame field. StoreObs
remains 152 bytes in the protected 160-byte allocation class; no wire
frames are retained. Existing dedup maps gain one pointer per slot only
at 64+ observations.
- Processing is linear in retained paths, bounded by 64 wire path bytes.
No new SQL, schema, configuration or maps.
- Tests cover five load/ingest paths, late duplicates,
analytics/adaptive thresholds, positive controls and concurrent readers.
Review correction `4ad6c5ad` preserves lazy decoded caches while
retaining escaped/legacy signature rejection.
- Full server suite, focused/race checks and frontend checks pass.
Browser verified on http://127.0.0.1:18905: both upstream false-positive
cases disappear and a genuine later FLOOD is recognized.

Independent review findings are addressed. Local preflight checks
passed; external home-directory bundle unavailable. [Final

AdamandClaude Opus 5.5 d777f4b7ce fix(ingestor): only flood relay hops refresh nodes.last_seen (#2307) (#2308)
Fixes #2307.

The ingestor refreshed `nodes.last_seen` for every resolved hop in a
path. For DIRECT routes those hops are still to come, and for TRACE
`path_json` is the route the trace was asked to take, so tracing or
messaging a switched-off repeater kept it looking recently heard.

## What changes

**`cmd/ingestor/db.go`**
- New `pathHopsTransmitted(data)`: true only when
`PathBytesAreHops(payloadType)` and the route is FLOOD or
TRANSPORT_FLOOD. It's the same rule as the server's `relayHopHexLen` in
`certain_heard.go`.
- `InsertTransmission` calls `touchRelayNodesLocked` only when that
holds. `observations.resolved_path` is still written for every
observation, so analytics are unchanged.
- The route and payload type come from the observation's own decoded
header (`PacketData`), not the transmission's first frame (see #2266).

## Perf

There's one integer comparison per observation, before the existing
touch. The touch now skips DIRECT and TRACE observations, so it does
fewer `UPDATE nodes` calls, never more.

## Tests

`cmd/ingestor/relay_touch_test.go`:
`TestInsertTransmission_TouchesOnlyFloodRelays` goes through
`InsertTransmission` with a real store and prefix index, using a node
whose 2-byte prefix is unique:

- FLOOD and TRANSPORT_FLOOD TXT_MSG: `last_seen` advances to the rx time
- DIRECT TXT_MSG and DIRECT TRACE: `last_seen` is unchanged

With `db.go` from master, the DIRECT and TRACE cases fail.

How I checked:
- `go vet ./...` and `go test ./...` in `cmd/ingestor` pass, and `gofmt
-l` is clean (`golang:1.27` container, since there's no local Go
toolchain).
- No server, frontend or schema changes, so I didn't run the browser and
E2E steps.

n30nex 410db29fe6 chore: remove unused legacy Dockerfiles (#2314)
Fixes #2310. Partial follow-up to #1385 (PR-C).

Remove unused `Dockerfile.go` and `Dockerfile.node`, which describe
retired alternate builds. Current workflows, Makefile, Compose variants
and operator scripts already select the canonical `Dockerfile`.

Remove the obsolete formatter exclusions and label the old Node-to-Go
migration guide historical, linking current deployment instructions.
Historical release prose remains untouched. The canonical image, runtime
files, dependencies and Compose behavior are unchanged.

Validation: audited all 1,501 tracked files; old and new formatter
inputs are exactly the same 633 real Go files. Both formatter commands,
YAML/shell/workflow-reference checks, existing workflow/routing tests,
COPY gate and test inventory pass. All 218 standalone frontend suites
pass. The unchanged backend tree passed full server/ingestor suites, and
the unchanged app passed 12 browser smoke cases.

TDD exemption: behavior-preserving cleanup/refactor plus documentation;
no test files modified. `make` and `actionlint` were unavailable
locally; equivalent formatter and focused workflow checks ran directly.

n30nex 3a85a98cc5 docs(api): describe the supported packet-list query parameters (#2294)
Red commit: `cee2a4bc` ([regression
CI](https://github.com/Kpa-clawbot/CoreScope/actions/runs/40203052113)).

Partial follow-up for #1670. GET /api/packets now documents all 16
supported query parameters, including hash, route, node(s), region,
channel, area and expand. It removes unsupported sort/timeRange/search
entries, corrects numeric types, and describes actual defaults, limits
and memory/SQL/multi-node differences.

This changes only packet-route metadata. Runtime API behavior and the
schema generator stay unchanged.

- Served-spec regressions fail on upstream while actual-route controls
pass.
- Focused OpenAPI/SwaggerUI tests, full server suite and full standalone
frontend suite pass on `d8014193`.
- Browser verified: http://127.0.0.1:18906/api/spec exposes the 16
supported parameters and integer types; the running packet route
confirms default limit 50 and offset 0.
- No new requests, dependencies, settings, schema or untyped-map
occurrences.

n30nex 041daecd1e docs(api): describe performance and clock diagnostics (#2303)
Partial follow-up to #1670.

Six existing read-only diagnostics endpoints lacked usable OpenAPI
descriptions: process I/O, SQLite metrics, ingestor write counters, and
fleet/node/observer clock skew. This documents their parameters,
empty/error behavior and response root shapes. The known-gap list falls
from 24 to 18.

Descriptions preserve current behavior, including unknown/empty area
fallback, the PacketStore cache ratio, stale write-counter snapshots,
and the single-node 404. Schemas remain minimal; the existing generator
still declares only the generic 200 response, with 404 explained in
prose.

No runtime handler, authentication, configuration or customizer changes.
No added generic response maps.

Validation: regression tests exercise the served spec and real router,
including missing/malformed data, area selection and fallback, and
calibration responses. Full server and ingestor tests pass locally;

immediately reading the badge could race with a theme refresh that

Fixes #2311. Partial follow-up to #1385 (PR-B).

Five historical release notes lived outside `docs/release-notes/`. Move
v2.6.0, v3.0.0, v3.1.0, v3.4.0 and v3.6.0 into that directory using its
existing version naming convention.

Release content is preserved except for concise historical notices and
four relative-link repairs. The v3.0.0 notice identifies its obsolete
Node rollback instructions; current setup links point to README and
DEPLOY. No new documentation hierarchy or index is introduced.

directly after Go setup, before gofmt/vet and backend builds/tests.
Failed unit checks then stop later work under the existing default

checks, coverage outputs and publication gates are unchanged. No new
job, package, timeout, cache or application setting.

Validation: dependency audit found no need for prior Go outputs. All 218
standalone suites passed with no checkout build artifacts or external
Node packages, after earlier shared Go tests had finished and cleaned
up. The parent reran the suite, parsed-workflow equivalence checks and
browser smoke. The unchanged backend tree passed both full backend
suites.

efitenandClaude Opus 5.5 e149568c6c feat(observer-logins): personal MQTT logins for observers (#2306)
Observers publish to the broker with one shared MQTT login. Anyone who
has that login can publish under any observer's topic, and the ingestor
takes the observer id from the topic (`cmd/ingestor/main.go:1009`), so
the data in the analyzer DB is only as trustworthy as the shared
password. This PR gives each user a personal MQTT login, generated and
mailed by CoreScope, and lets the broker ask CoreScope whether a login
may connect and publish.

Closes #2319.

The feature is optional and off by default
(`userManagement.observerLogins.enabled`). It needs
`userManagement.enabled`. With it off, nothing changes.

## Changes in this PR

**Broker hooks.** `POST /api/mqtt-hook/emqx/authn` and `/authz`, for the
EMQX HTTP authenticator and authorizer.
- They check a shared secret header, `X-CoreScope-Hook-Secret`, in
constant time.
- A username CoreScope does not know gets `ignore`, so EMQX falls
through to its built-in database and existing users keep working.
- A personal login may only publish `meshcore/<iata>/<pubkey>/<type>`,
with a 64-hex pubkey that is unbound or bound to the same user.
- The first publish for an unbound pubkey binds that observer to the
user (first come wins), until the user owns 20 observers (admin
assignments count too).
- An admin can rebind any observer.

**Credentials.**
- Username `obs_` + 12 random `[a-z0-9]`, password 32 random
`[A-Za-z0-9]`, both from `crypto/rand`.
- The password is stored twice: SHA-256 for the auth check, and sealed
with AES-256-GCM (key from config or `CORESCOPE_OBSERVER_KEY`) so the
user can ask for the same credentials again.
- The UI and the API never show the password. It leaves the server only
in the mail.

**Mail.** One mail with four formats:
- the meshcoretomqtt TOML;
- the observer firmware CLI commands (Gessaman or Dutch-MeshCore, same
`mqttN` CLI), on slot 4: slots 1-2 (Gessaman, Let's Mesh US/EU) and 1-3
(Dutch-MeshCore, `MQTTDefaults.h:19-34`) hold default broker presets on
a fresh install, slot 4 is empty on both. `set mqtt4.server` gets the
bare host: the firmware picks the scheme from the port
(`MQTTBridge.cpp:2094-2145`), and builds before merge 32dd8ad
(2026-10-19) do not accept a scheme there (read from the source, not
tested on a device). A scheme is written only when the port would pick
the wrong one, for example TLS on 8884;
- the Home Assistant meshcore-ha broker form fields;
- the plain values.

Each block starts with a numbered title and one line on where it goes.
The account page can resend the mail, at most 3 times per 24 h.

**Account and admin UI.**
- The account page gets an "Observer MQTT login" section
(`#/account?section=observers`) with the username, the bound observers
and the resend button.
- The admin page gets an "Observer logins" tab
(`#/admin?tab=observer-logins`) that lists logins with revoke and
reissue, and every observer with its owner, "not migrated" or
"orphaned", with a reassign control.

**Notifications.** Creating a login adds `observer.offline.own` ("My
observers go offline") to the owner's notification events; mails go out
once the user has notifications switched on, and the user can untick it.

**Storage.** users.db schema v7 adds `mqtt_logins` and
`observer_bindings`. The server still writes only users.db through
`internal/users`, and the analyzer DB stays read-only.

**Docs.** `docs/observer-mqtt-logins.md` covers the EMQX setup (authn
and authz chains, the hook body templates, the closing `^obs_` deny rule
and why it is needed), how to enable it on a running EMQX through the
REST API step by step, with a check and a rollback per step, and how to
migrate observers off a shared login. `config.example.json` has the
block with placeholder values.

## Enabling it on an instance

Full steps in `docs/observer-mqtt-logins.md`. In short:

1. **CoreScope:** add `userManagement.observerLogins` to `config.json`
with `enabled: true`, a `hookSecret` (`openssl rand -hex 32`), an
`encryptionKey` (`openssl rand -base64 32`) and the `broker` host, port,
transport and TLS that observers should use. Restart. Keep the key safe:
without it, mails cannot be resent and logins must be reissued.
2. **EMQX, authorization:** add a file source with `{deny, {username,
{re, "^obs_"}}, all, ["#"]}.` and move it to the end, then add the HTTP
authorizer pointing at `/api/mqtt-hook/emqx/authz` (it lands at the
front).
3. **EMQX, authentication:** add the HTTP authenticator pointing at
`/api/mqtt-hook/emqx/authn` and move it to the front, before the
built-in database.
4. **Check:** the shared login still connects, an unknown `obs_` login
is refused, and `metrics.deny` on the authorizer stays 0 for existing
clients.
5. **Owners:** they request a login on their account page and paste the
block for their uploader. Each observer binds to them on its first
publish. An uploader that was refused before step 3 may need a restart.
6. **Later:** remove the shared login from the broker once enough
observers moved.

## Who can claim an observer

Any active account can request a login, and its first publish under an
unbound pubkey binds that observer, also when CoreScope already knew it
from the shared login (first come wins, a deliberate choice: owners
migrate without waiting for an admin). Observer pubkeys are public, and
registration cannot be closed, so with this feature on anyone with a
mail address can claim up to 20 unbound observers per account. Before,
publishing needed the shared password.

What limits it: each claim of a known observer mails the admins, an
admin can unbind or reassign it and revoke the login, and a bound
observer cannot be claimed by another login. The doc spells this out and
suggests assigning known observers to their owners before announcing the
feature. A stricter mode (admin approval of logins, or no auto-bind for
known observers) is not in this PR.

## Performance

`authorize()` runs for every publish that misses the EMQX authz cache.
It takes two short read locks, does map lookups and one topic split.
`BenchmarkAuthorizeBound` (2000 observers, 500 logins): 533.5 ns/op, 96
B/op, 2 allocs/op. The admin observers table renders once per load and
updates single rows after a change.

## Verification

- All 16 Go modules: `bash scripts/allmod.sh test ./...` green.
- Skipped `TestSaveGeoFilterPreservesFileMode` and
`TestWriteStatsAtomic_SymlinkAtDestIsReplaced`: both fail on Windows on
a clean master too.
- `sh test-all.sh` green.
- `tests/e2e/test-user-management-e2e.js` 36/36 locally. It covers:
request, mail, resend, revoke, reissue, reassign, no password in the
page or API body, and axe. The CI job for this suite gets the
`observerLogins` block with fake values in `deploy.yml`.
- Local EMQX 5.8.6 in Docker against a local CoreScope:
- a personal login connects and publishes, which binds the observer; a
second personal login is denied on that observer's topic, and subscribe
is denied;
- with CoreScope stopped, the built-in users still connect and publish,
and new personal-login connects are refused;
- the `^obs_` deny rule blocks an already-connected personal login while
CoreScope is down; without the rule, the same publish was delivered.

- Production: running on an EMQX 5.8.9 broker with about 50 clients
since 2026-10-25, set up through the REST API as in the doc. After the
hooks went in, the authorizer answered `ignore` for every existing login
(0 denies, 0 dropped messages), and 4 observers were bound to their
owners through personal logins on the same evening, with the shared
login still in use by the rest.

## Known behaviour

EMQX's HTTP client can mark the hook resource down for one health-check
interval (15 s measured) when CoreScope closes an idle keep-alive
connection just as a health check runs. During that window new
personal-login connects are refused and the uploader reconnects. I saw
it 3 times in about 25 minutes of runs with a forced 1-5 s idle timeout,
and could not trigger it on demand. EMQX 5.8.6 has no setting for it,
and 5.10.5 ships the same client code. The doc describes it and the
alarm to watch for.

## Not in this PR

- mosquitto (mosquitto-go-auth). EMQX only.
- A websocket path field: the mail does not carry one, the doc tells
operators to match the listener path.
- Disabling the shared login. That is an operator step after migration,
described in the doc.
- Tested on EMQX 5.8.6 (Docker) and 5.8.9 (production) only.

Note on cb9f4ff3: its message says the scheme problem was reported by an
operator. That report turned out to come from before the broker used the
hook, so it does not show this cause; the change rests on the firmware
source only.

efitenandClaude Opus 5.5 11ce123505 fix(rx-coverage): English tooltips for the leaderboard score and cells columns (#2280)
## Problem

The RX coverage leaderboard has two column tooltips in Dutch, since
#1728 (`public/rx-coverage.js:340` and `:342`). The rest of the UI is
English.

## Change

- **score:** now says what `cmd/server/rx_dashboard.go:362-366`
computes. Each ~150 m cell (`leaderboardHexRes = 13`,
`rx_dashboard.go:264`) adds 1 divided by the number of observers that
heard something there, so an unshared cell counts 1 and a cell shared
with 3 others counts 0.25.
- **cells:** a plain translation.

No logic changes, so there is no new test. `sh test-all.sh` passes. Not
done: no browser check of the tooltips.

Noticed in the review of #2269, which had picked the Dutch text up as an
English key.

n30nex cb38ac356c fix(packets): preserve All time across reloads and links (#2279)
Desktop All time now survives reloads and shared links, including a
selected older grouped packet and observation. An explicit zero is
retained in storage and the URL; missing/invalid values still use the
default. Mobile requests retain their existing time and row limits.

Fixes #2231.

Validation: RED reproduces the lost zero; all standalone frontend suites
and the unchanged server suite pass. The local main browser suite
(`test-e2e-playwright.js`) passes 149 checks with three explicit
fixture-dependent skips. The gesture suite also preserves the existing
time window when opening a packet trace. The new regression covers
selection, reload, fresh links, older grouped observations and mobile
bounds.

Normalization is constant work; URL updates reuse the existing
serializer and add no requests. No new settings or dependencies. Common
ingestor validation is covered by the separate #2272 test-stability
change.


[Exact-head
CI](https://github.com/Kpa-clawbot/CoreScope/actions/runs/40160982457)
passed on commit 5278ade6, including all three browser shards.

n30nex b3367f5aea fix(analytics): keep distance indexing lazy during startup (#2278)
Chunked startup now leaves the distance index lazy, as the legacy loader
already does. Requests wait for the initial chunks to finish, then
trigger one build and publish the refreshed result. A terminal
initial-load failure returns a clear error instead of retrying forever;
a completed hot window remains usable if later background filling fails.

Fixes #2227.

Validation: RED reproduces eager and premature builds plus the
terminal-error retry loop. Full server and unchanged frontend suites
pass, with focused race checks. The browser/API check observed 202 then
200, nonempty distances, and exactly one build.

Performance evidence is the test-enforced absence of eager/duplicate
distance construction, with required path indexes retained. No timing
speedup is claimed. No new settings. Common ingestor validation is
covered by the separate #2272 test-stability change.
2026-10-25 12:11:09 +01:00
n30nex 77c0392947 fix(reach): avoid caching interrupted query results (#2277)
Reach now propagates failed scope lookups, rejects cancelled results
before caching, and retains the prior complete degree snapshot when
scanning or row iteration fails. Missing rows and optional scope columns
still produce the legitimate empty result.

Fixes #2258.

Validation: RED reproduces partial degree snapshots and cached success
after failed/cancelled follow-up queries. The full server and unchanged
frontend suites pass; focused race and browser Reach checks pass.
Handler regressions verify that failed builds do not replace caches and
that a later request rebuilds successfully.

The shared-build cancellation policy and query count are unchanged. This
is independent of #2249's admission/queue work. Common ingestor
validation is covered by the separate #2272 test-stability change.
2026-10-25 12:10:58 +01:00
n30nex c085ca8cba fix(rf-params): respect node visibility in responses (#2276)
The RF endpoint now applies the current blacklist and hidden-name policy
to both exposed node metadata and deviations, including after cache
warm-up. Unhiding a node restores its data without waiting for cache
expiry.

Fixes #2268.

The shared RF snapshot and peer calculation remain unchanged; filtering
copies only the response data. This adds a linear node pass and bounded
deviation copies, with no additional database calls or cache
invalidation. The feature remains opt-in.

Validation: RED reproduces both response leaks. The full server and
standalone frontend suites pass, as do focused race tests and the RF
browser suite. Regressions cover warm/cold caches, policy updates,
unhide, visible controls and default-off behavior. Common ingestor
validation is covered by the separate #2272 test-stability change.
2026-10-25 12:10:47 +01:00
n30nex 82aafb53c3 fix(analytics): count roles within selected filters (#2275)
Analytics Nodes now counts roles from the same complete, filtered node
list used by Network Status. Region/area selections no longer display
the API's global role totals. The global API metadata remains available
to other consumers.

Fixes #2213.

Validation: RED reproduces the mismatching totals; all standalone
frontend suites and the unchanged server suite pass. Browser checks
cover region and area changes and empty results. Regressions also cover
501-node pagination, unknown roles, unchanged metadata and request
counts.

Counting happens inside the existing O(n) status pass, using six bounded
counters and no additional requests. No configuration changes. Common
ingestor validation is covered by the separate #2272 test-stability
change.
2026-10-25 12:10:36 +01:00
n30nex 7ebbed58dc fix(analytics): anchor resize handles to table headers (#2274)
Resize handles now use their static table header as the containing
block. Already-positioned headers, including sticky Nodes headers,
retain their existing positioning.

Fixes #2217.

Validation: assertion-failing RED commit followed by the fix; all
standalone frontend suites and the unchanged server suite pass. The
browser suite passes 48 checks covering desktop/mobile bounds, real
dragging, saved widths and sticky headers. The browser regression waits
for the initial theme render before measuring.

The fix adds one positioning check per header during setup, with no new
requests, dependencies or settings. Common ingestor validation is
covered by the separate #2272 test-stability change.
2026-10-25 12:10:25 +01:00
n30nex 12e0a40a82 test: make hop coverage clock checks deterministic (#2273)
Three hop-coverage tests sampled the clock before database setup, then
allowed only five seconds of drift. Slow setup made otherwise correct
coverage checks fail. They now use the existing clock hook, restore it
after fixture workers finish, and assert exact equality. Production code
is unchanged.

Fixes #2272.

Validation: the original full run reproduced all three failures; the
corrected full ingestor suite passes. Focused race checks pass, and
row/deletion/ordering assertions remain intact. This is a test-only
stabilization of existing failing assertions, not a new runtime feature.

efitenandClaude Opus 5.5 7fa86fe1c1 docs(release-notes): v3.15.0 (#2263)
Release notes for v3.15.0: `docs/release-notes/v3.15.0.md` and the
`CHANGELOG.md` entry. The release workflow uses the notes file as the
GitHub release body.

## What is in it

- 77 commits since v3.14.0 (76 merged pull requests plus this one): 27
fix, 23 perf, 19 feat, 3 test, 2 ci, 2 docs, 1 chore. Nineteen feats, so
minor.
- "Read this before upgrading" first. It covers:
  - the liveness change (#2261, #2262);
- the `users.db` v6 migration and what it means for a rollback (#2174);
- the backfill at every ingestor start (#2133) and the 24 h
planner-statistics refresh (#2158);
- the caches that trade freshness for latency (#2165, #2222, #2147,
#2156);
- changes in hop names and region placement (#2188, #2190, #2234, #2245,
#2220);
  - the role thresholds on favorites (#2215);
  - the geo-filter save on a single-file mount (#2137);
  - the `/api/stats` polling in hidden tabs (#2162).
- Features, fixes, performance, then tests/CI/docs.
- 29 issues closed, taken from each pull request's
`closingIssuesReferences`.
- Contributors: pull request authors and issue reporters with counts.
The commit co-author trailers only name the pull request's own author or
tooling.

## How it was checked

- I read every pull request body. Every number in the notes comes from a
pull request body.
- I checked the config keys and defaults against `config.example.json`
on `2bb000f2`.
- I checked the UNASKED and opt-in claims for #2125, #2133, #2235 and
#2239 against the source.
- For the other pull requests I relied on their bodies and did not open
the diffs.

## Not covered

- The uncertain count is a single count on one staging instance on the
day of the change (1,682 repeaters and rooms). It is not a before/after
comparison.
- #2133 gives no measured cost for its backfill on a large database, and
the notes say so.

## After merge

Tag `v3.15.0` on the merge commit once its `:edge` image exists. Then
check in the registry that `v3.15.0`, `v3.15`, `v3` and `latest` share
one digest, and that the release has the notes as its body and both
`corescope-decrypt` binaries.

efitenandClaude Opus 5.5 2bb000f2aa feat(notify): adaptive offline threshold and certain node analytics (#2260) (#2262)
Part 2 of #2260. **Builds on #2261** (certain liveness): review/merge
that first; until then this diff also shows its commit.

## Adaptive offline threshold

`userManagement.notifications.adaptiveOffline` — **off by default**:

```json
"notifications": {
  "enabled": true,
  "adaptiveOffline": { "enabled": true, "floorMinutes": 30, "minObservers": 3 }
}
```

The fixed `infraSilentHours` (72 h) treats every repeater the same. With
this on, a watched node's `node.offline` window is learned from its own
**certain** traffic (the #2261 rule):

1. Certain packets per hour over the week **before its last certain
packet**. Ending there, not at now, keeps an outage from dragging the
rate down until the fixed window returns and the node reads "back
online".
2. Empty runs are classified: ≤ 6 h and recurring on another day at the
same hours = normal silence (kept; the window is never shorter than the
longest + 1 h); any other run = outage, left out of the learning so it
neither stretches the window nor blocks learning.
3. λ = 10th percentile of the remaining hourly counts, so quiet nights
don't alert.
4. Window = 14/λ hours: silence at rate λ has a < 10⁻⁶ chance (Poisson,
ln 10⁶ ≈ 13.8).
5. Clamped to [`floorMinutes`, the role's silent window].

Kept on the fixed window: λ < 1/hour, under 24 h of history in memory,
or a 10th-percentile hour heard by fewer than `minObservers` observers
(one observer dropping out must not read as the node going offline).
Silence is measured up to the newest packet in the store, so a stalling
feed stops every node's clock. A node stored offline comes back only on
evidence from the moment it went offline on. The notifier caches each
learned window for 10 minutes and drops unwatched nodes.

For the #2260 repeater (~840 packets/day) the mail would have gone out
about 30 minutes into the outage, instead of never (or 72 h with #2261
alone).

## Certain node analytics

- Each `activityTimeline` bucket carries `certain`: the part that can
only be this node (`certainFor`, the packet-level form of the
`certainHeard` rule). `TimeBucket.Certain` is `omitempty`, so other
endpoints are unchanged.
- Availability and longest silence use certain buckets only; the longest
silence now includes one **still running** (an outage in progress is the
silence worth seeing).
- The chart stacks certain (`--accent`) and uncertain (`--text-muted`) —
existing theme variables, so no new customizer entry. Descriptions
updated.

## Performance

`CertainActivity` walks a week of packets per watched node, at most once
per node per 10 minutes, with the read lock taken **per node**:

```
BenchmarkCertainActivity-16   12.1 ms/op   (50 watched repeaters × 6,000 packets; ~0.25 ms per lock hold)
BenchmarkNoteCertainRelays-16  121 ns/op   0 allocs
```

Node analytics adds one `certainFor` per packet of the requested node (a
prefix-map lookup, or the cached decoded JSON for its own packets).

## Tests

- `adaptiveOfflineAfter`: busy repeater hits the floor; 5/hour; quiet
nights set the rate; > 10 % empty hours, short history, too few
observers → fixed.
- `CertainActivity` ends at the last certain packet and counts only
certain packets — verified red by mutating the window to end at now.
- Notifier end to end: learned window passed → bad; inside → good; too
few observers / setting off → fixed 72 h; cache refresh and prune.
- `certainFor`, `longestSilence` (incl. running silence), config
defaults, `/api/nodes/{pk}/analytics` splits a shared-prefix bucket.
- Frontend: `NodeAnalyticsTimeline.series` (new
`tests/unit/test-node-analytics-certain-timeline.js`).
- `cmd/server` `go test ./...` and `test-all.sh` pass locally, also on a
trial merge into a downstream fork.

## Validation

Server on the freshened e2e fixture: analytics buckets carry `certain`
(e.g. 89 of 90 packets certain for one repeater). **No browser
screenshot**: Playwright isn't installed on this machine.

## Later (rule 8)

`floorMinutes` / `minObservers` are server config, not theme settings;
an admin UI for notification settings would be the place, not the
customizer.

efitenandClaude Opus 5.5 a08f2f4e7c fix(liveness): count only evidence that can be the node alone (#2260) (#2261)
Fixes #2260 (part 1 of 2: liveness; the adaptive offline threshold
follows in a separate PR).

## Problem

A repeater silent since 2026-10-18 showed **Active — Last relayed 4m
ago** and **Last Heard 36m**, and its offline mail never fired. Every
hit after that date was the 1-byte hop `67`, shared by nine nodes:

- the live resolver's affinity tiebreak (`resolvePathForObs`) put those
transmissions in `byNode`, which fed `stats.lastHeard` and
`LastHeardMap`;
- `last_relayed` folds in the 1-byte prefix bucket on purpose (#662),
and drove the status in `roles.js` and the notify offline check.

## Fix

The store keeps `certainHeard` per node: the newest transmission that
can only be that node.

| Evidence | Counts? |
|---|---|
| Own packet (`pubKey`, `srcPubKey`) | ✅ |
| Flood relay hop whose prefix, at the packet's path hash size, matches
exactly one path-capable node | ✅ |
| 1-byte hop shared with other repeaters | ❌ |
| Direct-route path (hops still to come, `Mesh::removeSelfFromPath`) | ❌
|
| TRACE (path bytes are SNR) | ❌ |
| Destination (`destPubKey`) | ❌ |

A multibyte repeater legitimately appears as a 1-byte hop (the
originator picks the hash size, `Mesh::routeRecvPacket` appends at that
size), so only uniqueness decides. The rule is applied in every load
path through `indexResolvedPathHops` and the new
`indexColdLoadRelayHops`: Load, loadChunk, scanAndMergeChunk, live
ingest, late observations.

Liveness reads only that:

- `/api/nodes` and the node detail: `last_heard` is the newer of
`last_seen` and the certain last heard. Before, it was a plain copy of
`last_seen`.
- health / bulk-health `stats.lastHeard`.
- `LastHeardMap` → notify offline check. The separate relay input
(`lastRelayed`, `relayTimes`, `notifyInput.Relayed`) is removed.
- `roles.js getEffectiveHeardMs`: newest known timestamp, without
`last_relayed`. The side pane no longer says "Last relayed"; the Last
Relayed row stays (analytics) with an updated tooltip.
- New status **`uncertain`** (repeaters and rooms): nothing certain
within the silent window, but the shared prefix (`last_relayed`) still
in paths. Grey badge with explanation, an *Uncertain* filter on the
nodes list and the map, dimmed like stale. The offline mail for such a
node says only its shared prefix was still seen.
- A prefix also held by a path-capable node in `inactive_nodes` is not
unique; adverts with `signatureValid: false` are no evidence;
`/api/nodes/search` reports the same `last_heard`.

Attribution for analytics (`byNode`, packet counts, `last_relayed`,
relay counters, usefulness) is unchanged.

## Performance

Hot path: `noteCertainRelays` runs per observation on ingest under the
write lock: two hex bytes of header parsing plus one prefix-map lookup
per resolved hop.

```
BenchmarkNoteCertainRelays-16   10307640   116.2 ns/op   0 B/op   0 allocs/op   (8-hop 2-byte path, 2,000 repeaters)
BenchmarkLastHeardMap-16            1902   0.77 ms/op                            (5,000 nodes; was 3.7 ms scanning byNode)
```

Memory: one string per node ever certainly heard, dropped together with
the node's `byNode` list on eviction.

## Tests

- `certain_heard_loadpaths_test.go`: every load path (Load, loadChunk,
LoadChunked — each with and without resolved_path — live ingest, late
observations) feeds `certainHeard`; each of the 8 call sites verified
red with a nil prefix map.
- `certain_heard_test.go`: hop width per route/payload type; retired
namesake prefix; failed signature; uncertain offline mail; shared vs
unique 1-byte vs 2-byte hops; direct/TRACE/nil prefix map; cold-load
path; sender vs destination; eviction; `lastHeardValue`; `/api/nodes`,
detail and health agree.
- Regression for #2260: last certain packet on day X, 20 shared-prefix
hops after it → `LastHeardMap` stays at X and `node.offline` goes bad
after 72 h. Verified red with the uniqueness check mutated out.
- Notify: `TestEvaluateCertainHeard` replaces the relay-input test.
- Frontend: `last_relayed` alone no longer keeps a repeater or room
active; newest timestamp wins (an old `_liveSeen` can't hide a fresh
certain relay).
- `cmd/server` `go test ./...` and `test-all.sh` pass locally, also on a
trial merge into a downstream fork with 457 extra commits.

## Validation

Ran the server on the freshened e2e fixture: list, detail and health
report the same last heard; e.g. a repeater whose `last_relayed` is 3
min newer than anything certain keeps its certain time. **No browser
screenshot**: Playwright isn't installed on this machine; CI's E2E
covers the pages.

## Not changed

- The ingestor's relay touch of `nodes.last_seen` (#1854) resolves a
shared hop only when exactly one candidate is adjacent in the neighbor
graph; it did not fire in this case. Left as is.
- The `lastHeard=` list filter still filters `last_seen` in SQL.

AdamandClaude Opus 5.5 dbcdca9dc5 feat(region-filter): honor ?region= in the URL on every page (#2255) (#2256)
Fixes #2255.

Only the packets page read `?region=` from the hash, with its own
one-off code. Live, nodes, observers, channels, analytics and scope
audit ignored it, so a link like this opened with whatever region the
visitor last picked:

```
https://<instance>/#/live?region=SJC
```

We link into our instance from a community directory (one link per
region), and wanted those links to land on the live map or node list
already filtered, not only on packets.

## What changes

**`public/region-filter.js`**
- `?region=` (comma-separated, trimmed) overrides the saved selection
and is saved like a click in the control, the same as packets did
through `setSelected()`.
- **Fresh load:** it's applied when the script runs, before any page
reads the selection. This matters for live, which fetches nodes before
it calls `RegionFilter.init()`.
- **In-app navigation:** `init()` applies it before its `await`, so a
page that loads after `init()` uses it. If it changed the selection,
listeners are told once regions load, so a page that already fetched
(live) reloads instead of showing the old region's data under the new
region's label.
- Unknown codes are dropped by the existing cleanup in `fetchRegions()`.
No param, or an empty one, leaves the saved selection alone.

**`public/packets.js`**
- Drops its own `_pendingUrlRegion` handling; `RegionFilter` covers it.
- Removes its region and area listeners in `destroy()`. They were
registered without a handle and outlived the page: after visiting
packets, a region change on any other page reloaded packets and
`replaceState`'d the URL to `#/packets?...` while you were on another
page. That already happened with the dropdown on master; the in-app
notify above would make it happen on every region link.

## Tests

`tests/unit/test-region-filter-url-param.js`, 14 assertions:
- URL region overrides the saved selection; comma lists, whitespace,
unknown codes, empty param, no param, no hash
- fresh load: selection is set before `init()` is called, and `init()`
doesn't notify
- in-app navigation: a changed region notifies listeners once, the same
region doesn't
- selection is saved to `localStorage`
- packets keeps handles for both listeners and removes them in
`destroy()`

With `region-filter.js` from master, 5 of the first 8 assertions fail.

How I checked:
- `test-all.sh` suites all pass except
`test-issue-1956-release-routing.js` and `test-preflight-xss-gate.js`.
Both also fail on unmodified master on macOS: they shell out to bash-4
features (`mapfile`, and a syntax error in `check-xss-sinks.sh` under
bash 3.2).
- `eslint@8.57.1` on the two files: 0 errors, 3 warnings, the same as
master.
- Browser: served `public/` locally with `/api` proxied to a live
instance and checked the requests each page made:
- fresh load of `#/nodes?region=AUS`, `#/live?region=DFW`,
`#/packets?region=HOU`: the first request carries the URL's region and
the dropdown shows it
- packets → `#/live?region=DFW`: live fetches with the old region, then
reloads with DFW; the dropdown shows DFW
- packets → `#/nodes?region=AUS`: no packets requests, and the URL stays
on `#/nodes`

I couldn't run the Playwright E2E suite locally (no Go toolchain on this
machine).

efitenandClaude Opus 5.5 0e3ce48cff feat(nodes): flag nodes whose LoRa settings differ from nearby nodes (#1268) (#2210)
Refs #1268. #2209 is merged as `cab4f71c`, and master is merged into
this branch (`47ce8264`), so the diff against master is this PR's own
change: `ea4d1130` plus the fix in `5cbbe5d5`.

## What it does

Two nodes hear each other only when SF and bandwidth match and their
frequencies are close enough. `/api/rf-params` now also returns
`deviations`: nodes whose setting differs from a majority of the nodes
around them on the same band.

- **Peers:** nodes with GPS and RF params within
`rfParams.compareRadiusKm` (default 50) whose frequency is within 30
MHz.
- **Same channel:** frequencies within a quarter of the bandwidth count
as one channel (15.625 kHz at BW 62.5). The SX1262 tolerates a
transmitter/receiver offset of up to 25% of BW without sensitivity loss,
for SF5 to SF12 and all bandwidths. Source: the `FERR_L` row in the
[S62F module
datasheet](https://lora-alliance.org/wp-content/uploads/2020/07/S62F_SPEC_Ver.B.pdf),
an SX1262 module; I did not find the figure in a Semtech document
itself. That table also lists -50/-100/-200 ppm for SF12/SF11/SF10,
which at 869 MHz is wider than BW/4 at 62.5 and 125 kHz, so BW/4 is the
tighter bound there.
- **Flagged when:** a setting the node cannot hear is shared by more
than half of the group, the node itself counted, with at least 3 peers
and no other incompatible setting at the same support. So 5 against 5
flags nobody, and 2 of 4 does not count as a majority. Each deviation
carries the majority, how many peers are compatible with it, the peer
count, and which of freq/sf/bw differ.
- **Coding rate is not compared.** RadioLib starts SX126x radios with an
explicit LoRa header (`SX126x::begin` sets
`RADIOLIB_SX126X_LORA_HEADER_EXPLICIT` at `6d89348`, the commit the
firmware pins in `platformio.ini`), and nothing in `firmware/src`
switches to implicit. The header carries the CR, so a CR mismatch still
decodes. I checked SX126x only, not SX127x or LR11x0.

UI:
- Nodes list: a badge such as `LoRa SF7` next to the name of a deviating
node (the majority in its tooltip), and a `LoRa: differs from nearby
(N)` filter kept in the URL as `?lora=differs`.
- Node detail: one line, for example "Differs from 12 of 14 nearby nodes
on this band, which use 869.618 MHz · SF8 · BW 62.5 kHz".
- Badge and filter only exist while the server has map data.

## Why same-band only

On our instance (1,110 nodes with params and GPS, measured with the
first version of the rule), a plain neighbourhood majority flagged
exactly 15 nodes, all of them a deliberate 433 MHz network in Limburg
next to the 868 MHz one (names like `NL-ZAY-RP01 | 433 X 868`). The
same-band comparison flags none there. On our network this PR shows
nothing today. The flags are for instances where a node really is set to
a different SF, bandwidth or channel than the nodes around it.

## Cost

- Points are bucketed on a radius-sized grid (rows of radius/110.57
degrees, longitude columns widened by 1/cos(lat)) and compared with a
squared equirectangular distance.
- `BenchmarkRfDeviations1k` (1,100 nodes over Belgium and the southern
Netherlands): 4.5 ms. `BenchmarkRfDeviations10k` (10,000 nodes in the
same box): 388 ms, 1.3 MB. Both on the first version.
- After `5cbbe5d5`, on a slower machine, 3 runs each: 1k 4.4 to 9.5 ms,
10k 821 to 852 ms, 1.8 MB. On that machine the first version measured
7.6 to 9.3 ms and 819 to 861 ms, so the majority step adds no measurable
time. It is one pass over the distinct settings around a node, and those
are few (one per preset in use).
- Inside the radius the work is close to O(n²): 10,000 nodes in one
dense box means about 2,000 neighbours per node, and a request after the
5 minute TTL waits for that computation.
- The result is cached per map snapshot for 5 minutes; concurrent
requests wait for one computation.
- On staging `/api/perf` reports `/api/rf-params` at 9.9 ms average, 26
ms max (8 requests).

## Tests

- Go: deviation cases (SF, freq within band, BW, CR ignored, other band
ignored, no GPS, no params, far away), split vote and too few peers,
radius, a peer in another longitude column at 60°N, the cache (same
snapshot within TTL, new snapshot, after TTL), the route with four
inserted nodes, plus the two benchmarks.
- Go, added in `5cbbe5d5`: a 5/5 split and 2 of 4 flag nobody; a 1 and a
15 kHz offset are not deviations while 32 kHz is, and offset peers add
up into one majority; the BW/4 boundary; peers two grid columns away at
60°N; a peer at the north edge of the radius. Each fails on the first
version. The two-column test also fails with a ±1 column search, which
the existing longitude test did not catch.
- Full `cmd/server` suite and `test-all.sh` pass locally on `5cbbe5d5`.
- Frontend unit: 6 new assertions for `deviationBadge` and the detail
line (13 in the file).
- E2E: 4 new checks: badge only on the deviating node, filter count and
result, `?lora=differs` written and restored, detail line. The disabled
check now also asserts no filter and no badges. 8/8 locally.

## Validation

On staging with live map data, with the first version: 1,115 nodes
served, `deviations: {}`, and the filter shows `LoRa: differs from
nearby (0)` with no badges. Because no real deviation exists there, the
badge, filter and detail line were checked by serving one simulated
deviation through Playwright route interception against the staging
page.

## Not done

- No map marker for deviating nodes.
- `compareRadiusKm` is config-only; the customizer is a later step. The
other values are hardcoded and belong in that step too: at least 3
peers, the 30 MHz band, the more-than-half rule, BW/4 and the 5 minute
TTL.
- Not re-run on staging after `5cbbe5d5`, and the E2E suite was not
re-run locally. The fix changes only the server's choice of nodes, not
the UI.
- The detail line says the peers "use" the majority setting. With the
BW/4 tolerance, some of them may be a few kHz off it.
- Companions and room servers are compared too, not only repeaters.
