efiten 0b35c7eef3 feat(server): persist multi-byte capability across restart + O(1) per-key lookup (#903) (#1324)
## Summary

Follows the reconciliation recommendation in #916 — extracts only the
NET-NEW persistence layer from that PR (which is now superseded by #1002
for the overlay UI) into a focused 6-file change against current master.

**What this adds:**
- `multibyte_sup_v1` migration: `multibyte_sup INTEGER NOT NULL DEFAULT
0` + `multibyte_evidence TEXT` on `nodes`/`inactive_nodes` so capability
survives restart
- `hasMultibyteSupCols` schema detection gates the persist/load paths
- `loadMultibyteCapFromDB()`: pre-populates `mbCapSnapshot`/`mbCapIndex`
at startup — cold starts serve last-known capability without waiting for
the first ~15s analytics cycle
- `maybePersistMultibyteCapability()` + `persistMultibyteCapability()`:
after each analytics cycle; TryLock-gated (concurrent cycles coalesce);
skips `sup==0` entries (data-destruction guard)
- `GetMultibyteCapFor(pk)`: O(1) map lookup; both `handleNodes` and
node-detail call sites updated from the O(N)-alloc
`GetMultiByteCapMap()`

**What this explicitly does NOT change:**
- API field names (`multi_byte_status`, `multi_byte_evidence`,
`multi_byte_max_hash_size`)
- `EnrichNodeWithMultiByte` — unchanged
- `GetMultiByteCapMap` — still present for any external callers
- `public/map.js`, `public/live.css`, `Dockerfile`, `docs/` — zero
frontend churn

## Test plan

- [x] `TestMultibyteCapPersistRoundTrip` — confirmed values survive
persist → fresh-store load
- [x] `TestMultibyteCapPersistSkipsUnknown` — data-destruction guard:
`sup==0` entry does not overwrite DB-confirmed value
- [x] `TestMultibyteCapMaybePersistCoalesces` — TryLock coalesces 10
concurrent callers without deadlock
- [x] `TestMultibyteCapGetMultibyteCapForO1` — O(1) index returns
correct entry / false for unknown pubkey
- [x] `TestMultibyteCapLoadFromDB` — only `sup>0` rows loaded; `sup==0`
row excluded
- [x] `TestSchemaMultibyteSupColumns` — migration adds columns to both
tables; idempotent on second `OpenStore`
- [x] All existing `TestMultiByteCapability_*` tests pass unchanged
- [x] Full ingestor test suite: `ok` in 27s
- [x] `go build ./cmd/server/ && go build ./cmd/ingestor/` clean

Kpa-clawbot de583f9df4 fix(paths-through): use canonical resolved_path instead of naive prefix match — fixes wrong-node attribution (#1352) (#1353)
## Summary
`/api/nodes/{pk}/paths` (paths-through-node) attributed the same
transmission to **every** prefix-sibling when their hop bytes collided
(e.g. 5 nodes with `c0…` on staging). Querying any of them returned the
tx — visible bug per #1352 where Kpa Roof Solar's view included a packet
whose actual relay was C0ffee SF.

## Root cause
`handleNodePaths` has two branches:

1. **Canonical resolved_path branch (#1278)** — when a tx has a
persisted `resolved_path`, membership is decided from the stored
pubkeys. This branch is correct.
2. **Fallback branch** — when `resolved_path` is NULL/missing, the code
invoked `pm.resolveWithContext(hop, []string{lowerPK}, graph)` to
re-resolve hops. The `hopContext=[lowerPK]` anchors the resolver on the
*queried target*, so the tier-2 (geo-proximity) / tier-3
(GPS+observation-count) tiers preferentially pick the target. Every
`paths-through-X` call for any `X` in the sibling set then resolved the
colliding hop to `X` and counted the tx — wrong-node attribution across
the whole sibling set.

## Fix
Server-side, query-time only. **No DB writes** (`#1289` read-only
invariant preserved). **No canonical-branch changes** — only the
fallback path.

In the fallback branch, accept a biased-resolver match as evidence of
target membership *only* when **either**:
- (a) the tx is already pre-confirmed via the resolved_path index hit or
SQL `INSTR(resolved_path, pubkey)` check, **or**
- (b) the hop's prefix candidate set is unique (`len(pm.m[hop]) <= 1`) —
no collision, no bias possible.

Multi-candidate prefix hops without independent SQL/index confirmation
are now treated as ambiguous and excluded from paths-through. Same rule
applied to the unresolvable-hop sub-case (when `resolveHop` returns nil
but the prefix could match the target).

## Which canonical resolved_path source is used
This PR does **not** introduce a new resolved_path source. It piggybacks
on what's already in place:
- **Canonical branch**: `s.store.fetchResolvedPathForTxBest(tx)` →
SQLite `observations.resolved_path` (populated upstream by the
hop-disambiguator from #1198/#1200/#1235).
- **Pre-confirmation in fallback**: `confirmedByFullKey` (membership
index `s.store.byPathHop[lowerPK]`) and `confirmedBySQL`
(`s.store.confirmResolvedPathContains` → `INSTR(LOWER(resolved_path),
"pubkey")`).

So when canonical data exists, attribution is purely persisted-path
driven; when it doesn't, attribution requires either a SQL pubkey hit or
a unique prefix candidate. Biased resolution alone is no longer
sufficient.

## TDD — red, then green
Two new tests in `cmd/server/paths_through_collision_1352_test.go`:

1. `TestHandleNodePaths_PrefixCollision_1352` — canonical branch
(already green via #1278). 3 nodes share `c0`, tx canonical
resolved_path = [B]. Only paths-through-B includes the tx.
2. `TestHandleNodePaths_PrefixCollision_1352_FallbackBranch` — **red**
before the fix. 3 GPS-having `c0` siblings, NULL resolved_path. Before:
A=1 B=1 C=1 (wrong-node attribution on all). After: ≤1 attribution.

Mutation: reverting the `len(pm.m[hop]) <= 1` guard in `routes.go`
restores the failing red state.

Existing tests preserved:
- `TestHandleNodePaths_PrefixCollisionExclusion` (#929) — still green.
- `TestHandleNodePaths_AnchorBiasInconsistency_Issue1278` (#1278) —
still green.
- Full `go test ./...` on `cmd/server` and `cmd/ingestor`: green.

## Acceptance criteria (from #1352)
- [x] On node detail for Kpa Roof Solar-shape, packet where actual relay
is C0ffee SF does NOT appear in paths-through (canonical branch test).
- [x] On node detail for C0ffee SF-shape, that same packet DOES appear
(canonical branch test).
- [x] Ambiguous fallback case (NULL resolved_path,
multi-prefix-collision) attributes to ≤1 node (fallback test).
- [x] Mutation test: removing the uniqueness guard makes the fallback
test fail.

## Out of scope
- Frontend UX for "ambiguous (N candidates)" badge (separate UX issue).
- Wider hop-disambiguator changes (#1198 family).

Fixes #1352

efiten 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

efiten 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 `#`).

efiten 51f823bf7e feat: one-click prune nodes outside geofilter (#669 M4) (#738)
## Summary

- Adds `POST /api/admin/prune-geo-filter` endpoint — dry-run by default,
`?confirm=true` to permanently delete nodes outside the current
geofilter polygon + buffer. Requires `X-API-Key` header.
- Adds **Prune nodes** section inside the GeoFilter customizer tab
(write-access only, same `writeEnabled` gate as PUT). **Preview** lists
affected nodes; **Confirm delete** removes them.
- Adds `GetNodesForGeoPrune` and `DeleteNodesByPubkeys` DB helpers.
- Updates `docs/user-guide/geofilter.md` — documents the UI button as
primary workflow, CLI script as alternative.

> **Depends on M3** (`feat/geofilter-m3-customizer`, PR #736). Merge M3
first.

## Test plan

- [x] `cd cmd/server && go test ./...` — all pass
- [x] Customizer GeoFilter tab without `apiKey` — Prune section not
visible
- [x] With `apiKey` + polygon active — Prune section visible
- [x] **Preview** returns list of nodes outside polygon (no deletions)
- [x] **Confirm delete** removes nodes, list clears
- [x] `POST /api/admin/prune-geo-filter` without `X-API-Key` → 401
- [x] `POST /api/admin/prune-geo-filter` with no polygon configured →
400

Kpa-clawbot 1da2034341 refactor(db): move all writes from server to ingestor; server truly read-only (fixes #1283) (#1286)
**Red commit:** f6290b63 — CI run will appear at
https://github.com/Kpa-clawbot/CoreScope/actions

Fixes #1283.

## What

Moves all four DB write operations out of `cmd/server/` into
`cmd/ingestor/`, making the server truly read-only and eliminating the
SQLITE_BUSY VACUUM bug at its root: the server can no longer race the
ingestor for the write lock because the server has no write path.

## The four operations

| # | Was in | Now in |
|---|--------|--------|
| 1 | `cmd/server/vacuum.go` (`checkAutoVacuum`, full VACUUM +
`auto_vacuum=INCREMENTAL` migration) | `cmd/ingestor/db.go`
`Store.CheckAutoVacuum` (already existed; ingestor runs it at startup
**before** the MQTT subscriber starts → no contention) |
| 2 | `cmd/server/db.go` `PruneOldPackets` (`DELETE FROM transmissions`)
| `cmd/ingestor/maintenance.go` `Store.PruneOldPackets` (new) + 24h
ticker in `cmd/ingestor/main.go` |
| 3 | `cmd/server/db.go` `PruneOldMetrics` (`DELETE FROM
observer_metrics`) | `cmd/ingestor/db.go` `Store.PruneOldMetrics`
(already existed) |
| 4 | `cmd/server/db.go` `RemoveStaleObservers` (`UPDATE observers SET
inactive=1`) | `cmd/ingestor/db.go` `Store.RemoveStaleObservers`
(already existed) |

## HTTP surface

- **Removed:** `POST /api/admin/prune` (`handleAdminPrune`, route,
openapi entry). Operators trigger an ad-hoc prune by restarting the
ingestor.
- **Kept:** `GET /api/backup` — uses `VACUUM INTO` which writes to a
separate file, not the live DB; read-only-safe.

## Tests

- `cmd/server/readonly_invariant_test.go` (RED gate) — reflect-asserts
`PruneOldPackets`/`PruneOldMetrics`/`RemoveStaleObservers` are NOT
methods on the server's `*DB`. Fails on master, passes after this PR.
- `cmd/ingestor/issue1283_test.go` — exercises `Store.PruneOldPackets`
and the auto_vacuum=NONE → INCREMENTAL migration through
`Store.CheckAutoVacuum` with `vacuumOnStartup=true`.

## Why the bug is gone

The SQLITE_BUSY VACUUM failure happened because supervisord launched
both ingestor + server in one container; the ingestor took the write
lock for INSERTs and the server's `checkAutoVacuum` then failed to
acquire it within `busy_timeout=5000`. After this PR, only the ingestor
ever opens a writable connection, and it runs `CheckAutoVacuum`
**before** spawning the MQTT subscriber → no contention possible.

## Scope notes

- `cachedRW()` still has three pre-existing callers in `cmd/server/`
(`neighbor_persist.go`, `ensure_indexes.go`,
`from_pubkey_migration.go`). These pre-date #1283 and are not in the
issue's four-operation list. Leaving them for follow-up keeps this PR
honest about scope; AGENTS.md documents the invariant so new write paths
can't sneak in.
- PII preflight reports false positives on the Go method name
`requireAPIKey` in `routes.go` diff context — no real PII.
- Server-side neighbor-edge prune (`PruneNeighborEdges`) intentionally
left in place — out of scope of #1283.

Kpa-clawbot d667dc0a74 fix(#1278): /api/nodes/{pk}/paths uses canonical persisted resolved_path (drop anchor-bias inconsistency) (#1282)
First failing (RED) commit: c994c5a7 — CI:
https://github.com/Kpa-clawbot/CoreScope/actions

Fixes #1278.

## Root cause
`handleNodePaths` (`cmd/server/routes.go`) anchored the disambiguator
with the queried node as `hopContext` (`hopContext :=
[]string{lowerPK}`). For ambiguous short-prefix hops (e.g. two nodes
sharing the 1-byte prefix `C0`), tier-1/2 hop-context resolution then
biased the resolver to pick the queried node — even though the CANONICAL
persisted `resolved_path` (what `/api/packets/{hash}` shows via
`fetchResolvedPathForTxBest`) had picked the OTHER colliding node at
ingest time. The `containsTarget` gate accepted those packets and
rendered the queried node into the displayed hop, while the packets page
(reading the canonical resolved_path) showed a different node. The two
pages disagreed.

Confirmed on staging: `/api/nodes/c0dedad…/paths` returned `sampleHash
6c4af39ee4b7e202`; `/api/packets/6c4af39ee4b7e202.resolved_path[3]` =
`c0ffeec7…`, not `c0dedad…`.

## Option chosen — A
For each candidate tx, read the canonical persisted `resolved_path` via
`fetchResolvedPathForTxBest`. When present, use it for BOTH:
- the `containsTarget` membership decision (queried pubkey must appear
in the canonical resolved hops), and
- the displayed hop names (zipped parallel to `tx.PathJSON`).

When absent (older data / async backfill not yet complete) the legacy
biased re-resolve is kept as a fallback — there's no canonical answer to
be consistent with, and dropping the bias unconditionally would regress
#1197.

## Why not B / C
- **B** (drop bias only for membership): still re-resolves display with
bias → display vs packets page can still diverge for hop names. Option A
fixes both.
- **C** (drop `hopContext` entirely): regresses #1197 / breaks the
`resolve_context_callsites_test.go` gate.

## Performance
Same O(N) walk over candidates; one extra `fetchResolvedPathForTxBest`
per candidate, LRU-cached, worst case a single SQL row.

## Tests
- RED: `cmd/server/paths_anchor_bias_test.go` — seeds two `c0…` nodes +
a tx whose best-obs resolved_path picks the GPS node; asserts the no-GPS
node's `/paths` excludes the tx and the GPS node's includes it.
Mutation-verified (fails on master).
- All existing tests green (including #1197 callsite gate and #929
prefix-collision exclusion).

Kpa-clawbot 8bf7709970 feat(repeater): usefulness score — bridge axis (#672 axis 2 of 4) (#1275)
RED test commit: `fd661569` — CI will fail on this (stub returns empty
map; assertions fail by design). GREEN: `bf4b8592`.

## What

Implements **axis 2 of 4** for the repeater usefulness score per #672
([status
comment](https://github.com/Kpa-clawbot/CoreScope/issues/672#issuecomment-4484635378)).
The Bridge axis measures *structural importance*: how many shortest
paths between other nodes route through this one. A high-traffic
redundant node and a low-traffic critical bridge will no longer look
identical.

## Algorithm

**Brandes' weighted betweenness centrality** with Dijkstra for shortest
paths (`cmd/server/bridge_score.go`).

- Nodes: pubkeys in the `neighbor_edges` graph
- Edge weight: `Score(now) * Confidence()` — per the convention from
#1235 (count + recency decay scaled by observer-diversity confidence).
Geo-rejected edges already excluded at graph build time (#1230) so we
don't re-filter here.
- Dijkstra distance: `1 / max(epsilon, weight)` — high affinity = cheap
cost.
- Normalize: divide by max observed centrality so output is in `[0, 1]`.

Cost: `O(V · (E + V log V))`. Staging-scale (~600 nodes / ~2 000 edges)
≈ ~4.8M ops, completes in milliseconds.

## Where it lives

- `cmd/server/bridge_score.go` — pure algorithm, no locks
- `cmd/server/bridge_recomputer.go` — background recomputer (mirrors
#1240/#1262 pattern), 5-min default interval, initial sync prewarm,
snapshot stored in `s.bridgeScoreMap atomic.Pointer[map[string]float64]`
- `cmd/server/routes.go` — `handleNodes` adds `node["bridge_score"]` on
repeater/room rows; node-detail handler adds it on the single-node path
- `public/nodes.js` — separate **Bridge** row in the node detail panel,
alongside the existing **Usefulness** (Traffic) row. Distinct
colour-coded bar.

## What's NOT in this PR (still pending for #672)

- **Coverage axis** (axis 3) — unique observer-pair connectivity
- **Redundancy axis** (axis 4) — simulated node-removal impact
- **Composite** — once all 4 axes ship, swap the `usefulness_score`
formula from "traffic-only" to the weighted composite

`Refs #672` (not `Fixes` — issue stays open until all 4 axes + composite
ship).

## Tests

- `TestComputeBridgeScores_LineGraph` — 4-node line: middles non-zero,
leaves zero, max normalized to 1.0
- `TestComputeBridgeScores_TriangleNoBridge` — clique has zero bridges
- `TestComputeBridgeScores_Empty` — defensive nil-safety
- `TestComputeBridgeScores_WeightSensitive` — mutation guard: revert the
`1/w` inversion and this test fails
- `TestBridgeScore_HandleNodesSurface` — integration: `/api/nodes`
returns `bridge_score` on repeater rows; middle nodes > 0, ends == 0

Kpa-clawbot 1efe93d7f6 perf(#1257): bulk-cache repeater enrichment in /api/nodes — 32s → <500ms (#1260)
RED commit `a2879e12` — perf regression test; CI run: see Actions tab.

Fixes #1257.

## Root cause

`handleNodes` looped over the response page and called
`store.GetRepeaterRelayInfo(pk, win)` +
`store.GetRepeaterUsefulnessScore(pk)` for every repeater/room. Each
call:

- grabbed its own `s.mu.RLock`,
- walked `byPathHop[pk]` (+ the matching 1-byte raw-prefix bucket, which
on busy networks fans out to nearly the entire non-advert tx set),
- and re-parsed every `tx.FirstSeen` with `parseRelayTS`.

Default page is the 50 most-recently-seen nodes — almost all hot
repeaters — so the request did O(50) lock acquisitions and hundreds of
thousands of timestamp parses on the same set of txs. That's the classic
load-then-paginate / per-row N+1 shape called out in the issue (same
family as #1226).

The `?limit=2000` variant looks faster relatively only because per-node
enrichment dwarfs serialization; on staging both still bottleneck on the
same loop.

## Fix

Two new bulk methods on `PacketStore`:

- `GetRepeaterRelayInfoMap(windowHours)` → `pubkey → RepeaterRelayInfo`
- `GetRepeaterUsefulnessScoreMap()` → `pubkey → 0..1`

Both snapshot `byPathHop` under a single `RLock`, pre-parse each
`FirstSeen` exactly once (a tx that appears in N hop buckets used to be
parsed N times), and emit one entry per hop key. Cached 15s — same TTL
as `GetNodeHashSizeInfo` / `GetMultiByteCapMap`, same status-column
freshness budget.

`handleNodes` is one map-lookup per node; behavior, output schema, and
`RelayActive` / `RelayCount{1h,24h}` / `LastRelayed` /
`usefulness_score` semantics are preserved.

## Why no `limit` default change

The issue mentioned a default-limit knob. Investigated: `queryInt(r,
"limit", 50)` already defaults to 50 — frontends calling `/api/nodes`
(no limit) get a 50-row page today. Capping further would change
behavior (live.js already passes `?limit=2000` when it wants more); the
cost was per-repeater enrichment, not page size. Fixing the N+1 is the
correct lever and preserves backward compat.

## Perf

Regression test `TestHandleNodesPerfLargeFleet` (600 nodes, 150k
non-advert tx, repeaters indexed under `byPathHop`):

| | elapsed | vs 2s budget |
|---|---|---|
| before (master) | 4.72s | ✗ |
| after | ~4ms | ✓ (~1000×) |

## TDD

- RED: `a2879e12` — test fails at 4.72s on master.
- GREEN: `c529d29a` — fix; full `cmd/server` + `cmd/ingestor` suites
green.

Kpa-clawbot b881a09f02 feat(#1188): show observer IATA on packets + filter grammar (#1189)
Red commit: 4ed272761b (CI run:
https://github.com/Kpa-clawbot/CoreScope/actions/runs/25651898290)

Fixes #1188 — observer IATA on packets in three UI surfaces + filter
grammar.

cross-stack: justified — feature spans API shape (Go), store, filter
grammar (JS), three packets UI surfaces.

## Scope shipped
- Packets table row: `.badge-iata` pill inline next to observer name
- Expanded observation rows: per-observation IATA badge
- Detail pane: Observer dd + per-observation list both render the badge
- Filter grammar: `observer_iata` field + `iata` alias;
`==`/`!=`/`contains`, plus a new `in (a, b, c)` list operator. Both
names appear in autocomplete with descriptions.

## TDD red→green pairs
1. `271d72f` filter-grammar tests → `2c182eb` evaluator + suggest
entries
2. `4ed2727` backend `observer_iata` API tests → `7856914` SQL join +
struct/store wiring
3. `0e09371` display E2E → `7a3f45d` packets.js + style.css badge
(E2E swapped for string-contract unit test in `ee414b4` — fixture
`observations.observer_idx` stores text pubkeys, blocking the join the
badge depends on)

## Backend
- `cmd/server/db.go`: SELECT `obs.iata AS observer_iata` in
`transmissionBaseSQL`, grouped query, observations-by-transmissions
- `cmd/server/store.go`: `ObserverIATA` on `StoreTx`/`StoreObs`, load
via all three ingest paths, surface in
`txToMap`/`enrichObs`/`groupedTxsToPage`
- `cmd/server/types.go`: field added to
`TransmissionResp`/`ObservationResp`/`GroupedPacketResp`
- Test fixture schemas declare `iata` on observers

## Perf
Per #383, `obsIataBadge(packet)` reads `packet.observer_iata` directly
(server-joined). Falls back to `observerMap.get(id).iata` only if absent
— hot row-render loop avoids per-row Map lookup on fresh data.

## Display rules
Missing IATA: nothing inline (Region column still shows `—`). No new hex
— `.badge-iata` uses `var(--nav-bg)` / `var(--nav-text)`.

E2E assertion added: test-observer-iata-1188.js:51

Kpa-clawbot eba9e89a72 fix(#1203): path-inspector — singleflight + stale-while-revalidate (#1208)
Red commit: c84a8f575a (CI run: pending
push)

Fixes #1203 — path-inspector 503 storm.

Three sub-fixes, each shipped as red→green per AGENTS TDD:

**A. Singleflight on rebuild** (`ensureNeighborGraph`)
Hand-rolled `sync.Mutex + chan` singleflight — no new deps (x/sync was
not in cmd/server's go.mod). Concurrent callers attach to one in-flight
rebuild instead of N parallel `BuildFromStore` goroutines.
- Red: `7340f23b` — test asserts ≤1 build under 10 concurrent callers
(saw 10 on master)
- Green: `abac6b3c`

**B. Stale-while-revalidate** (`handlePathInspect`)
Stale non-nil graph is served immediately with `"stale": true` while a
background rebuild runs (deduped by A). The 2s synchronous gate is gone.
Stale responses are not cached, so the next request after rebuild lands
fresh.
- Red: `c84a8f57` — test asserts 200+`stale:true`+rebuild-kickoff
(master returned 503)
- Green: `5eb86975`

**C. Cold-start 503 still kicks rebuild**
True cold start (`graph == nil`) is the only path that still returns 503
`{"retry": true}`, but it now spawns an async `ensureNeighborGraph` so
the very next request warms up.
- Green test: `f5ac7059` (passed on top of A+B)

Singleflight verified: `TestEnsureNeighborGraph_Singleflight`
Stale-while-revalidate verified:
`TestHandlePathInspect_StaleWhileRevalidate`
Cold-start verified: `TestHandlePathInspect_ColdStartKicksRebuild`

**Acceptance criteria (issue #1203):**
- [x] Concurrent requests share ONE rebuild
- [x] Stale non-nil graph served with `stale:true` async
- [x] 503 only on true cold-start
- [x] Cold-start 503 kicks rebuild → follow-up warm
- [ ] p99 < 500ms under load (not unit-testable; design satisfies it)
- [x] No regression in existing tests

**Out of scope (per issue):** 5-min TTL constant, `BuildFromStore` perf,
`/api/analytics/topology`, persist-lock contention.

No new deps.

Kpa-clawbot 353c5264ad fix(#1197): plumb hop-context + observation-count tiebreak to disambiguator (#1198)
Red commit: 5ffdf6b07c (CI run: pending —
see PR Checks tab)

Fixes #1197

## What this changes

Two-part fix matching the issue spec:

1. **Tier-3/4 tiebreak by observation count, not slice order**
(`store.go` resolver + `getAllNodes`).
- Plumbs `nodes.advert_count` → new `nodeInfo.ObservationCount` field
via the existing `getAllNodes` query (graceful fallback when the column
is absent on legacy DBs).
- `resolveWithContext` tier 3 (GPS preference) now picks the GPS-having
candidate with the highest observation count.
- Tier 4 (no-GPS fallback) likewise picks by observation count instead
of `candidates[0]`.
2. **Plumb hop-context to the resolver** at all four call sites called
out in the issue.
- New `buildHopContextPubkeys(tx, pm)` collects: sender pubkey from
`tx.DecodedJSON.pubKey`, observer pubkey from `tx.ObserverID`, plus
unambiguous-prefix anchors (single-candidate prefixes in the path).
- Wired into the four sites: broadcast distance compute (~1707),
recompute-on-path-change (~2944), `buildDistanceIndex` (~2982),
`computeAnalyticsTopology` (~5125).
- Per-tx hop caches were moved inside the per-tx loop on the distance
paths since context now varies per tx (was safely shared before only
because every caller passed `nil`).
- `computeAnalyticsTopology` aggregates context across the analytics
scan rather than per-tx because `resolveHop` is called outside the scan
loop downstream.

## Tests

Red→green pairs visible in the commit history:

- Pair A — tier-3 observation-count tiebreak
(`TestResolveWithContext_Tier3_PicksHigherObservationCount`).
- Pair B — context plumbing
(`TestBuildHopContextPubkeys_IncludesSenderAndUnambiguousAnchors`) +
tier-2 geo-proximity
(`TestResolveWithContext_Tier2_PicksGeographicallyCloserCandidate`).

`go test ./...` green on `cmd/server`.

## Out of scope (per issue)

300 km hop cap, API confidence/alternative-count surfacing, firmware
prefix-collision space — all explicitly excluded in #1197.

Kpa-clawbot fb744d895f fix(#1143): structural pubkey attribution via from_pubkey column (#1152)
Fixes #1143.

## Summary

Replaces the structurally unsound `decoded_json LIKE '%pubkey%'` (and
`OR LIKE '%name%'`) attribution path with an exact-match lookup on a
dedicated, indexed `transmissions.from_pubkey` column.

This closes both holes documented in #1143:
- **Hole 1** — same-name false positives via `OR LIKE '%name%'`
- **Hole 2a** — adversarial spoofing: a malicious node names itself with
another node's pubkey and gets attributed to the victim
- **Hole 2b** — accidental false positive when any free-text field (path
elements, channel names, message bodies) contains a 64-char hex
substring matching a real pubkey
- **Perf** — query now uses an index instead of a full-table scan
against `LIKE '%substring%'`

## TDD

Two-commit history shows red-then-green:

| Commit | Status | Purpose |
|---|---|---|
| `7f0f08e` | RED — tests assertion-fail on master behaviour |
Adversarial fixtures + spec |
| `59327db` | GREEN — schema + ingestor + server + migration |
Implementation |

The red commit's test schema includes the new column so the file
compiles, but the production code still uses LIKE — the assertions fail
because the malicious / same-name / free-text rows are returned. The
green commit changes the query plus adds the migration/ingest path.

## Changes

### Schema
- new column `transmissions.from_pubkey TEXT`
- new index `idx_transmissions_from_pubkey`

### Ingestor (`cmd/ingestor/`)
- `PacketData.FromPubkey` populated from decoded ADVERT `pubKey` at
write time. Cheap — already parsing `decoded_json`. Non-ADVERTs stay
NULL.
- `stmtInsertTransmission` writes the column.
- Migration `from_pubkey_v1` ALTERs legacy DBs to add the column +
index.
- Bonus: rewrote the recipe in the gated one-shot
`advert_count_unique_v1` migration to use `from_pubkey` (already marked
done on existing DBs; kept correct for fresh installs).

### Server (`cmd/server/`)
- `ensureFromPubkeyColumn` mirrors the ingestor migration so the server
can boot against a DB the ingestor has never touched (e2e fixture, fresh
installs).
- `backfillFromPubkeyAsync` runs **after** HTTP starts. Scans `WHERE
from_pubkey IS NULL AND payload_type = 4` in 5000-row chunks with a
100ms yield between chunks. Cannot block boot even on prod-sized DBs
(100K+ transmissions). Queries handle NULL gracefully (return empty for
that pubkey, same as today's unknown-pubkey path).
- All in-scope LIKE call sites switched to exact match:

| Site | Before | After |
|---|---|---|
| `buildPacketWhere` (was db.go:582) | `decoded_json LIKE '%pubkey%'` |
`from_pubkey = ?` |
| `buildTransmissionWhere` (was db.go:626) | `t.decoded_json LIKE
'%pubkey%'` | `t.from_pubkey = ?` |
| `GetRecentTransmissionsForNode` (was db.go:910) | `LIKE '%pubkey%' OR
LIKE '%name%'` | `t.from_pubkey = ?` |
| `QueryMultiNodePackets` (was db.go:1785) | `decoded_json LIKE
'%pubkey%' OR ...` | `t.from_pubkey IN (?, ?, ...)` |
| `advert_count_unique_v1` (was ingestor/db.go:257) | `decoded_json LIKE
'%' \|\| nodes.public_key \|\| '%'` | `t.from_pubkey = nodes.public_key`
|

`GetRecentTransmissionsForNode` signature simplifies: the `name`
parameter is gone (it was only ever used for the legacy `OR LIKE
'%name%'` fallback). Sole caller in `routes.go:1243` updated.

### Tests
- `cmd/server/from_pubkey_attribution_test.go` — adversarial fixtures +
Hole 1/2a/2b/QueryMultiNodePackets exact-match assertions, EXPLAIN QUERY
PLAN index check, migration backfill correctness.
- `cmd/ingestor/from_pubkey_test.go` — write-time correctness
(BuildPacketData populates FromPubkey for ADVERT only;
InsertTransmission persists it; non-ADVERTs stay NULL).
- Existing test schemas (server v2, server v3, coverage) get the new
column **plus a SQLite trigger** that auto-populates `from_pubkey` from
`decoded_json` on ADVERT inserts. This means existing fixtures (which
only seed `decoded_json`) keep attributing correctly without per-test
edits.
- `seedTestData`'s ADVERTs explicitly set `from_pubkey`.

## Performance — index is used

```
$ EXPLAIN QUERY PLAN SELECT id FROM transmissions WHERE from_pubkey = ?
SEARCH transmissions USING INDEX idx_transmissions_from_pubkey (from_pubkey=?)
```

Asserted in `TestFromPubkeyIndexUsed`.

## Migration approach

- **Sync at boot**: `ALTER TABLE transmissions ADD COLUMN from_pubkey
TEXT` is a metadata-only operation in SQLite — microseconds regardless
of table size. `CREATE INDEX IF NOT EXISTS
idx_transmissions_from_pubkey` is **not** metadata-only: it scans the
table once. Empirically a few hundred ms on a 100K-row table; expect a
few seconds on a 10M-row table (one-time cost, blocking boot during that
window). Subsequent boots no-op via `IF NOT EXISTS`. If this boot delay
becomes an operational concern at prod scale we can defer the `CREATE
INDEX` to a goroutine — for now a few-second one-time delay is
acceptable.
- **Async**: row-level backfill of legacy NULL ADVERTs (chunked 5000 /
100ms yield). On a 100K-ADVERT prod DB, this completes in seconds in the
background; HTTP is fully available throughout.
- **Safety**: queries handle NULL gracefully — a node whose ADVERTs
haven't backfilled yet returns empty, identical to today's behaviour for
unknown pubkeys. No half-state regression.

## Out of scope (intentionally)

The free-text `LIKE` paths the issue explicitly leaves alone (e.g.
user-typed packet search) are untouched. Only the pubkey-attribution
sites get the column treatment.



## Cycle-3 review fixes

| Finding | Status | Commit |
|---|---|---|
| **M1c** — async-contract test was tautological (test's own `go`, not
production's) | Fixed | `23ace71` (red) → `a05b50c` (green) |
| **m1c** — package-global atomic resets unsafe under `t.Parallel()` |
Fixed (`// DO NOT t.Parallel` comment + `Reset()` helper) | rolled into
`23ace71` / `241ec69` |
| **m2c** — `/api/healthz` read 3 atomics non-atomically (torn snapshot)
| Fixed (single RWMutex-guarded snapshot + race test) | `241ec69` |
| **n3c.m1** — vestigial OR-scaffolding in `QueryMultiNodePackets` |
Fixed (cleanup) | `5a53ceb` |
| **n3c.m2** — verify PR body language about `ALTER` vs `CREATE INDEX` |
Verified accurate (already corrected in cycle 2) | (no change) |
| **n3c.m3** — `json.Unmarshal` per row in backfill → could use SQL
`json_extract` | **Deferred as known followup** — pure perf optimization
(current per-row Unmarshal is correct, just slower); SQL rewrite would
unwind the chunked-yield architecture and is non-trivial. Acceptable for
one-time backfill at boot on legacy DBs. |

### M1c implementation detail

`startFromPubkeyBackfill(dbPath, chunkSize, yieldDuration)` is now the
single production entry point used by `main.go`. It internally does `go
backfillFromPubkeyAsync(...)`. The test calls `startFromPubkeyBackfill`
(no `go` prefix) and asserts the dispatch returns within 50ms — so if
anyone removes the `go` keyword inside the wrapper, the test fails.
**Manually verified**: removing the `go` keyword causes
`TestBackfillFromPubkey_DoesNotBlockBoot` to fail with "backfill
dispatch took ~1s (>50ms): not async — would block boot."

### m2c implementation detail

`fromPubkeyBackfillTotal/Processed/Done` are now plain `int64`/`bool`
package globals guarded by a single `sync.RWMutex`.
`fromPubkeyBackfillSnapshot()` returns all three under one RLock.
`TestHealthzFromPubkeyBackfillConsistentSnapshot` races a writer
(lock-step total/processed updates with periodic done flips) against 8
readers hammering `/api/healthz`, asserting `processed<=total` and
`(done => processed==total)` on every response. Verified the test
catches torn reads (manually injected a 3-RLock implementation; test
failed within milliseconds with "processed>total" and "done=true but
processed!=total" errors).

Kpa-clawbot 74dffa2fb7 feat(perf): per-component disk I/O + write source metrics on Perf page (#1120) (#1123)
## Summary

Implements per-component disk I/O + write source metrics on the Perf
page so operators can self-diagnose write-volume anomalies (cf. the
BackfillPathJSON loop debugged in #1119) without SSHing in to run
iotop/fatrace.

Partial fix for #1120

## What's done (4/6 ACs)
-  `/api/perf/io` — server-process `/proc/self/io` delta rates
(read/write bytes per sec, syscalls)
-  `/api/perf/sqlite` — WAL size, page count, page size, cache hit rate
-  `/api/perf/write-sources` — per-component counters from ingestor
(tx/obs/upserts/backfill_*)
-  Frontend Perf page — three new sections with anomaly thresholds +
per-second rate columns

## What's NOT done (deferred to follow-up)
-  `cancelledWriteBytesPerSec` field — issue #1120 lists this under
server-process I/O ("writes the kernel discarded — interesting signal");
not exposed in this PR
-  Ingestor `/proc/<pid>/io` — issue #1120 says "Both ingestor and
server"; only server-process I/O lands here. Adding ingestor I/O
requires either a unix socket back to the server, or surfacing the
ingestor pid through the stats file. Doable without changing the
existing API shape.
-  Adaptive baselining — anomaly thresholds remain static (10×, 100 MB,
90%); steady-state baselining can come once we have enough deployed
Perf-page telemetry

Per AGENTS.md rule 34, this PR uses "Partial fix for #1120" rather than
"Fixes #1120" so the issue stays open until the remaining ACs land.

## Backend

**Server (`cmd/server/perf_io.go`)**
- `GET /api/perf/io` — reads `/proc/self/io` and returns delta-rate
`{readBytesPerSec, writeBytesPerSec, syscallsRead, syscallsWrite}` since
last call (in-memory tracker, no allocation per sample).
- `GET /api/perf/sqlite` — returns `{walSize, walSizeMB, pageCount,
pageSize, cacheSize, cacheHitRate}`. `cacheHitRate` is proxied from the
in-process row cache (closest available signal under the modernc sqlite
driver).
- `GET /api/perf/write-sources` — reads the ingestor's stats JSON file
and returns a flat `{sources: {...}, sampleAt}` payload.

**Ingestor (`cmd/ingestor/`)**
- `DBStats` gains `WALCommits atomic.Int64` (incremented on every
successful `tx.Commit()` and on every auto-commit `InsertTransmission`
write) and `BackfillUpdates sync.Map` keyed by backfill name with
`IncBackfill(name)` / `SnapshotBackfills()` helpers.
- `BackfillPathJSONAsync` now increments `BackfillUpdates["path_json"]`
per row write — the BackfillPathJSON-style infinite loop becomes
immediately visible at `backfill_path_json` in the Write Sources table.
- New `StartStatsFileWriter` publishes a JSON snapshot to
`/tmp/corescope-ingestor-stats.json` (override via
`CORESCOPE_INGESTOR_STATS`) every second using atomic tmp+rename. The
tmp file is opened with `O_CREATE|O_WRONLY|O_TRUNC|O_NOFOLLOW` mode
`0o600` so a pre-planted symlink in a world-writable `/tmp` cannot
redirect the write to an arbitrary file.

## Frontend (`public/perf.js`)

Three new sections on the Perf page, all auto-refreshed via the existing
5s interval:

- **Disk I/O (server process)** — read/write rates (formatted
B/KB/MB-per-sec) + syscall counts. Write rate >10 MB/s flags ⚠️.
- **Write Sources** — sorted table of per-component counters with a
per-second rate column derived from snapshot deltas. Backfill rows show
⚠️ only when `tx_inserted >= 100` (meaningful baseline) AND the
backfill's per-second rate exceeds 10× the live tx rate. Avoids the
startup-spurious-alarm where cumulative-vs-cumulative was a tautology.
- **SQLite (WAL + Cache Hit)** — WAL size (⚠️ when >100 MB), page count,
page size, cache hit rate (⚠️ when <90%).

## Tests

- **Backend** (`cmd/server/perf_io_test.go`) —
`TestPerfIOEndpoint_ReturnsValidJSON`,
`TestPerfSqliteEndpoint_ReturnsValidJSON`,
`TestPerfWriteSourcesEndpoint_ReturnsSources` exercise the three new
endpoints. Skips the `/proc/self/io` non-zero-rate assertion when
`/proc` is unavailable.
- **Frontend** (`test-perf-disk-io-1120.js`) — vm-sandbox runs `perf.js`
with stubbed `fetch`, asserts the three new sections render with their
headings + values.

E2E assertion added: test-perf-disk-io-1120.js:91

## TDD

1. Red commit (`21abd22`) — added the three handlers as no-op stubs
returning empty values; tests fail on assertion mismatches (non-zero
rate, `pageSize > 0`, headings present).
2. Green commit (`d8da54c`) — fills in the real `/proc/self/io` parser,
PRAGMA queries, ingestor stats writer, and Perf page rendering.

Kpa-clawbot 136e1d23c8 feat(#730): foreign-advert detection — flag instead of silent drop (#1084)
## Summary

**Partial fix for #730 (M1 only — M2 frontend and M3 alerting
deferred).**

Today the ingestor **silently drops** ADVERTs whose GPS lies outside the
configured `geo_filter` polygon. That's the wrong default for an
analytics tool — operators get zero visibility into bridged or leaked
meshes.

This PR makes the new default **flag, don't drop**: foreign adverts are
stored, the node row is tagged `foreign_advert=1`, and the API surfaces
`"foreign": true` so dashboards / map overlays can be built on top.

## Behavior

| Mode | What happens to an ADVERT outside `geo_filter` |
|---|---|
| (default) flag | Stored, marked `foreign_advert=1`, exposed via API |
| drop (legacy) | Silently dropped (preserves old behavior for ops who
want it) |

## What's done (M1 — Backend)
- ingestor stores foreign adverts instead of dropping
- `nodes.foreign_advert` column added (migration)
- `/api/nodes` and `/api/nodes/{pk}` expose `foreign: true` field
- Config: `geofilter.action: "flag"|"drop"` (default `flag`)
- Tests + config docs

## What's NOT done (deferred to M2 + M3)

- **M2 — Frontend:** Map overlay showing foreign adverts as distinct
markers, foreign-advert filter on packets/nodes pages, dedicated
foreign-advert dashboard
- **M3 — Alerting:** Time-series detection of bridging events, alert
when foreign advert rate spikes, identify bridge entry-point nodes

Issue #730 remains open for M2 and M3.

Kpa-clawbot 3ab404b545 feat(node-battery): voltage trend chart + /api/nodes/{pubkey}/battery (#663) (#1082)
## Summary

Closes #663 (Phase 2 + 3 partial — time-series tracking + thresholds for
nodes that are also observers).

Adds a per-node battery voltage trend chart and
`/api/nodes/{pubkey}/battery` endpoint, sourced from the existing
`observer_metrics.battery_mv` samples populated by observer status
messages. No new ingest or schema changes — purely surfaces data we were
already collecting.

## Scope (TDD red→green)

**RED commit:** test(node-battery) — DB query, endpoint shape
(200/404/no-data), and config getters all asserted.
**GREEN commit:** feat(node-battery) — implementation only.

## Changes

### Backend
- `cmd/server/node_battery.go` (new):
- `DB.GetNodeBatteryHistory(pubkey, since)` — pulls `(timestamp,
battery_mv)` rows from `observer_metrics WHERE LOWER(observer_id) =
LOWER(public_key) AND battery_mv IS NOT NULL`. Case-insensitive join
tolerates historical pubkey casing variation (observers persist
uppercase, nodes lowercase in this DB).
- `Server.handleNodeBattery` — `GET /api/nodes/{pubkey}/battery?days=N`
(default 7, max 365). Returns `{public_key, days, samples[], latest_mv,
latest_ts, status, thresholds}`.
- `Config.LowBatteryMv()` / `CriticalBatteryMv()` — defaults 3300 / 3000
mV.
- `cmd/server/config.go` — `BatteryThresholds *BatteryThresholdsConfig`
field.
- `cmd/server/routes.go` — route registration alongside existing
`/health`, `/analytics`.

### Frontend
- `public/node-analytics.js` — new "Battery Voltage" chart card with
status badge (🔋 OK / ⚠️ Low / 🪫 Critical / No data). Renders dashed
threshold lines at `lowMv` and `criticalMv`. Empty-state message when no
samples in window.

### Config
- `config.example.json` — `batteryThresholds: { lowMv: 3300, criticalMv:
3000 }` with `_comment` per Config Documentation Rule.

## Status semantics

| latest_mv             | status     |
|-----------------------|------------|
| no samples in window  | `unknown`  |
| `>= lowMv`            | `ok`       |
| `< lowMv`, `>= critMv`| `low`      |
| `< criticalMv`        | `critical` |

## What this PR does NOT do (deferred)

The issue's full Phase 1 (writing decoded sensor advert telemetry into
`nodes.battery_mv` / `temperature_c` from server-side decoder) and Phase
4 (firmware/active polling for repeaters without observers) are out of
scope here. This PR delivers the requested Phase 2/3 surfacing for the
data path that already lands rows: `observer_metrics`. Repeaters that
are also observers (i.e. publish status to MQTT) will get a voltage
trend immediately; pure passive nodes won't until Phase 1 lands.

## Tests

- `TestGetNodeBatteryHistory_FromObserverMetrics` — case-insensitive
join, NULL skipping, ordering.
- `TestNodeBatteryEndpoint` — full happy path with thresholds + status.
- `TestNodeBatteryEndpoint_NoData` — 200 + status=unknown.
- `TestNodeBatteryEndpoint_404` — unknown node.
- `TestBatteryThresholds_ConfigOverride` — config getters + defaults.

`cd cmd/server && go test ./...` — green.

## Performance

Endpoint is per-pubkey (called once on analytics page open), indexed by
`(observer_id, timestamp)` PK on `observer_metrics`. No hot-path impact.

Kpa-clawbot f33801ecb4 feat(repeater): usefulness score — traffic axis (#672) (#1079)
## Summary

Implements the **Traffic axis** of the repeater usefulness score (#672).
Does NOT close #672 — Bridge, Coverage, and Redundancy axes are deferred
to follow-up PRs.

Adds `usefulness_score` (0..1) to repeater/room node API responses
representing what fraction of non-advert traffic passes through this
repeater as a relay hop.

## Why traffic-axis-first

The issue proposes a 4-axis composite (Bridge, Coverage, Traffic,
Redundancy). Bridge/Coverage/Redundancy require betweenness centrality
and neighbor graph infrastructure (#773 Neighbor Graph V2). Traffic axis
can ship independently using existing path-hop data.

## Remaining work for #672

- Bridge axis (betweenness centrality — depends on #773)
- Coverage axis (observer reach comparison)
- Redundancy axis (node-removal simulation — depends on #687)
- Composite score combining all 4 axes

Partial fix for #672.

Kpa-clawbot 45f30fcadc feat(repeater): liveness detection — distinguish actively relaying from advert-only (#662) (#1073)
## Summary

Implements repeater liveness detection per #662 — distinguishes a
repeater that is **actively relaying traffic** from one that is **alive
but idle** (only sending its own adverts).

## Approach

The backend already maintains a `byPathHop` index keyed by lowercase
hop/pubkey for every transmission. Decode-window writes also key it by
**resolved pubkey** for relay hops. We just weren't surfacing it.

`GetRepeaterRelayInfo(pubkey, windowHours)`:
- Reads `byPathHop[pubkey]`.
- Skips packets whose `payload_type == 4` (advert) — a self-advert
proves liveness, not relaying.
- Returns the most recent `FirstSeen` as `lastRelayed`, plus
`relayActive` (within window) and the `windowHours` actually used.

## Three states (per issue)

| State | Indicator | Condition |
|---|---|---|
| 🟢 Relaying | green | `last_relayed` within `relayActiveHours` |
| 🟡 Alive (idle) | yellow | repeater is in the DB but
`relay_active=false` (no recent path-hop appearance, or none ever) |
|  Stale | existing | falls out of the existing `getNodeStatus` logic |

## API

- `GET /api/nodes` — repeater/room rows now include `last_relayed`
(omitted if never observed) and `relay_active`.
- `GET /api/nodes/{pubkey}` — same fields plus `relay_window_hours`.

## Config

New optional field under `healthThresholds`:

```json
"healthThresholds": {
  ...,
  "relayActiveHours": 24
}
```

Default 24h. Documented in `config.example.json`.

## Frontend

Node detail page gains a **Last Relayed** row for repeaters/rooms with
the 🟢/🟡 state badge. Tooltip explains the distinction from "Last Heard".

## TDD

- **Red commit** `4445f91`: `repeater_liveness_test.go` + stub
`GetRepeaterRelayInfo` returning zero. Active and Stale tests fail on
assertion (LastRelayed empty / mismatched). Idle and IgnoresAdverts
already match the desired behavior under the stub. Compiles, runs, fails
on assertions — not on imports.
- **Green commit** `5fcfb57`: Implementation. All four tests pass. Full
`cmd/server` suite green (~22s).

## Performance

`O(N)` over `byPathHop[pubkey]` per call. The index is bounded by store
eviction; a single repeater has at most a few hundred entries on real
data. The `/api/nodes` loop adds one map read + scan per repeater row —
negligible against the existing enrichment work.

## Limitations (per issue body)

1. Observer coverage gaps — if no observer hears a repeater's relay,
it'll show as idle even when actively relaying. This is inherent to
passive observation.
2. Low-traffic networks — a repeater in a quiet area legitimately shows
idle. The 🟡 indicator copy makes that explicit ("alive (idle)").
3. Hash collisions are mitigated by the existing `resolveWithContext`
path before pubkeys land in `byPathHop`.

Fixes #662

Kpa-clawbot b06adf9f2a feat: /api/backup — one-click SQLite database export (#474) (#1022)
## Summary

Implements `GET /api/backup` — one-click SQLite database export per
#474.

Operators can now grab a complete, consistent snapshot of the analyzer
DB with a single authenticated request — no SSH, no scripts, no DB
tooling.

## Endpoint

```
GET /api/backup
X-API-Key: <key>            # required
→ 200 OK
  Content-Type: application/octet-stream
  Content-Disposition: attachment; filename="corescope-backup-<unix>.db"
  <body: complete SQLite database file>
```

## Approach

Uses SQLite's `VACUUM INTO 'path'` to produce an atomic, defragmented
copy of the database into a fresh file:

- **Consistent**: VACUUM INTO runs at read isolation — the snapshot
reflects a single point in time even while the ingestor is writing to
the WAL.
- **Non-blocking**: writers continue uninterrupted; we never hold a
write lock.
- **Works on read-only connections**: verified manually against a
WAL-mode source DB (`mode=ro` connection successfully produces a
snapshot).
- **No corruption risk**: even if the live on-disk DB has issues, VACUUM
INTO surfaces what the server can read rather than copying broken pages
byte-for-byte.

The snapshot is staged in `os.MkdirTemp(...)` and removed after the
response body is fully streamed (deferred cleanup). Requesting client IP
is logged for audit.

The issue suggested an alternative in-memory rebuild path; `VACUUM INTO`
is simpler, faster, and produces a strictly more accurate copy of what
the server actually sees, so going with it.

## Security

- Mounted under `requireAPIKey` middleware — same gate as other admin
endpoints (`/api/admin/prune`, `/api/perf/reset`).
- Returns 401 without a valid `X-API-Key` header.
- Returns 403 if no API key is configured server-side.
- `X-Content-Type-Options: nosniff` set on the response.

## TDD

- **Red** (`99548f2`): `cmd/server/backup_test.go` adds
`TestBackupRequiresAPIKey` + `TestBackupReturnsValidSQLiteSnapshot`.
Stub handler returns 200 with no body so the tests fail on assertions
(Content-Type / Content-Disposition / SQLite magic header), not on
import or build errors.
- **Green** (`837b2fe`): real implementation lands; both tests pass;
full `go test ./...` suite stays green.

## Files

- `cmd/server/backup.go` — handler implementation
- `cmd/server/backup_test.go` — red-then-green tests
- `cmd/server/routes.go` — route registration under `requireAPIKey`
- `cmd/server/openapi.go` — OpenAPI metadata so `/api/openapi`
advertises the endpoint

## Out of scope (follow-ups)

- Rate limiting (issue suggested 1 req/min). Not added here —
admin-key-gated endpoint with a fast snapshot path is acceptable for v1;
happy to add a token-bucket limiter in a follow-up if operators report
hammering.
- UI button to trigger the download (frontend work — separate PR).

Kpa-clawbot 51b9fed15e feat(roles): /#/roles page + /api/analytics/roles endpoint (Fixes #818) (#1023)
## Summary

Implements `/#/roles` per QA #809 §5.4 / issue #818. The page previously
showed "Page not yet implemented."

### Backend
- New `GET /api/analytics/roles` returns `{ totalNodes, roles: [{ role,
nodeCount, withSkew, meanAbsSkewSec, medianAbsSkewSec, okCount,
warningCount, criticalCount, absurdCount, noClockCount }] }`.
- Pure `computeRoleAnalytics(nodesByPubkey, skewByPubkey)` does the
bucketing/aggregation — no store/lock dependency, fully unit-testable.
- Roles are normalised (lowercased + trimmed; empty bucketed as
`unknown`).

### Frontend
- New `public/roles-page.js` renders a distribution table: count, share,
distribution bar, w/ skew, median |skew|, mean |skew|, severity
breakdown (OK / Warning / Critical / Absurd / No-clock).
- Registered as the `roles` page in the SPA router and linked from the
main nav.
- Auto-refreshes every 60 s, with a manual refresh button.

### Tests (TDD)
- **Red commit** (`9726d5b`): two assertion-failing tests against a stub
`computeRoleAnalytics` that returns an empty result. Compiles, runs,
fails on `TotalNodes = 0, want 5` and `len(Roles) = 0, want 1`.
- **Green commit** (`7efb76a`): full implementation, route wiring,
frontend page + nav, plus E2E test in `test-e2e-playwright.js` covering
both the empty-state contract (no "Page not yet implemented"
placeholder) and the populated-table case (header columns, body rows,
API response shape).

### Verification
- `go test ./cmd/server/...` green.
- Local server with the e2e fixture: `GET /api/analytics/roles` returns
`{"totalNodes":200,"roles":[{"role":"repeater","nodeCount":168,...},{"role":"room","nodeCount":23,...},{"role":"companion","nodeCount":9,...}]}`.

Kpa-clawbot a56ee5c4fe feat(analytics): selectable timeframes via ?window/?from/?to (#842) (#1018)
## Summary
Selectable analytics timeframes (#842). Adds backend support for
`?window=1h|24h|7d|30d` and `?from=&to=` on the three main analytics
endpoints (`/api/analytics/rf`, `/api/analytics/topology`,
`/api/analytics/channels`), and a time-window picker in the Analytics
page UI that drives them. Default behavior with no query params is
unchanged.

## TDD trail
- Red: `bbab04d` — adds `TimeWindow` + `ParseTimeWindow` stub and tests;
tests fail on assertions because the stub returns the zero window.
- Green: `75d27f9` — implements `ParseTimeWindow`, threads `TimeWindow`
through `compute*` loops + caches, wires HTTP handlers, adds frontend
picker + E2E.

## Backend changes
- `cmd/server/time_window.go` — full `ParseTimeWindow` (`?window=`
aliases + `?from=/&to=` RFC3339 absolute range; invalid input → zero
window for backwards compatibility).
- `cmd/server/store.go` — new
`GetAnalytics{RF,Topology,Channels}WithWindow` wrappers; `compute*`
loops skip transmissions whose `FirstSeen` (or per-obs `Timestamp` for
the region+observer slice) falls outside the window. Cache key composes
`region|window` so different windows do not poison each other.
- `cmd/server/routes.go` — handlers call `ParseTimeWindow(r)` and
dispatch to the `*WithWindow` methods.

## Frontend changes
- `public/analytics.js` — new `<select id="analyticsTimeWindow">`
rendered under the region filter (All / 1h / 24h / 7d / 30d). Selecting
an option triggers `loadAnalytics()` which appends `&window=…` to every
analytics fetch.

## Tests
- `cmd/server/time_window_test.go` — covers all aliases, absolute range,
no-params backwards compatibility, `Includes()` bounds, and `CacheKey()`
distinctness.
- `cmd/server/topology_dedup_test.go`,
`cmd/server/channel_analytics_test.go` — updated callers to pass
`TimeWindow{}`.

## E2E (rule 18)
`test-e2e-playwright.js:592-611` — opens `/#/analytics`, asserts the
picker is rendered with a `24h` option, then asserts that selecting
`24h` triggers a network request to `/api/analytics/rf?…window=24h`.

## Backwards compatibility
No params → zero `TimeWindow` → original code paths (no filter,
region-only cache key). Verified by
`TestParseTimeWindow_NoParams_BackwardsCompatible` and by the existing
analytics tests still passing unchanged on `_wt-fix-842`.

Fixes #842

Kpa-clawbot df69a17718 feat(#772): short pubkey-prefix URLs for mesh sharing (#1016)
## Summary

Fixes #772 — adds a short-URL form for node detail pages so operators
can paste node links into a mesh chat without bringing along a
64-hex-char public key.

## Approach

**Pubkey-prefix resolution** (no allocator, no lookup table).

- The SPA hash route `#/nodes/<key>` already accepts whatever
pubkey-shaped string the user pastes; the front end forwards it to `GET
/api/nodes/<key>`.
- When that lookup misses **and** the path is 8..63 hex chars, the
backend now calls `DB.GetNodeByPrefix` and:
  - returns the matching node when exactly one node has that prefix,
- returns **409 Conflict** when multiple nodes share the prefix (with a
"use a longer prefix" hint),
  - falls through to the existing 404 otherwise.
- 8 hex chars = 32 bits of entropy, which is enough for fleets in the
low thousands. Operators can extend to 10–12 chars if collisions become
common.
- The full-screen node detail card gets a new **📡 Copy short URL**
button that copies `…/#/nodes/<first 8 hex chars>`.

### Why not an opaque ID table (`/s/<id>`)?

Considered and rejected:

- Needs persistence + an allocator + cleanup story.
- IDs aren't self-describing — operators can't sanity-check them.
- IDs don't survive a DB rebuild.
- 32 bits of pubkey already buys us collision resistance with zero
moving parts.

If the directory grows past the point where 8-char prefixes routinely
collide, we can extend the minimum length without changing the URL
shape.

## Changes

- `cmd/server/db.go` — new `GetNodeByPrefix(prefix)` returning `(node,
ambiguous, error)`. Validates hex; rejects <8 chars; `LIMIT 2` to detect
collisions cheaply.
- `cmd/server/routes.go` — `handleNodeDetail` falls back to prefix
resolution; canonicalizes pubkey downstream; emits 409 on ambiguity;
honors blacklist on the resolved pubkey.
- `public/nodes.js` — adds **📡 Copy short URL** button + handler on the
full-screen node detail card.
- `cmd/server/short_url_test.go` — Go tests (red-then-green).
- `test-e2e-playwright.js` — E2E: navigates via prefix-only URL and
asserts the new button surfaces.

## TDD evidence

- Red commit: `2dea97a` — tests added with a stub `GetNodeByPrefix`
returning `(nil, false, nil)`. All four assertions failed (assertion
failures, not build errors): expected node got nil; expected
ambiguous=true got false; route 404 vs expected 200/409.
- Green commit: `9b8f146` — implementation lands; `go test ./...` passes
locally in `cmd/server`.

## Compatibility

- Existing 64-char pubkey URLs are untouched (exact lookup runs first).
- Blacklist is enforced both on the raw input and on the resolved
pubkey.
- No new config knobs.

## What I did **not** touch

- `cmd/server/db_test.go`, other route tests — unchanged.
- Packet-detail short URLs (issue scopes nodes; revisit in a follow-up
if asked).

Fixes #772

Kpa-clawbot e86b5a3a0c feat: show multi-byte hash support indicator on map markers (#1002)
## Summary

Show 2-byte hash support indicator on map markers. Fixes #903.

## What changed

### Backend (`cmd/server/store.go`, `cmd/server/routes.go`)

- **`EnrichNodeWithMultiByte()`** — new enrichment function that adds
`multi_byte_status` (confirmed/suspected/unknown), `multi_byte_evidence`
(advert/path), and `multi_byte_max_hash_size` fields to node API
responses
- **`GetMultiByteCapMap()`** — cached (15s TTL) map of pubkey →
`MultiByteCapEntry`, reusing the existing `computeMultiByteCapability()`
logic that combines advert-based and path-hop-based evidence
- Wired into both `/api/nodes` (list) and `/api/nodes/{pubkey}` (detail)
endpoints

### Frontend (`public/map.js`)

- Added **"Multi-byte support"** checkbox in the map Display controls
section
- When toggled on, repeater markers change color:
  - 🟢 Green (`#27ae60`) — **confirmed** (advertised with hash_size ≥ 2)
- 🟡 Yellow (`#f39c12`) — **suspected** (seen as hop in multi-byte path)
  - 🔴 Red (`#e74c3c`) — **unknown** (no multi-byte evidence)
- Popup tooltip shows multi-byte status and evidence for repeaters
- State persisted in localStorage (`meshcore-map-multibyte-overlay`)

## TDD

- Red commit: `2f49cbc` — failing test for `EnrichNodeWithMultiByte`
- Green commit: `4957782` — implementation + passing tests

## Performance

- `GetMultiByteCapMap()` uses a 15s TTL cache (same pattern as
`GetNodeHashSizeInfo`)
- Enrichment is O(n) over nodes, no per-item API calls
- Frontend color override is computed inline during existing marker
render loop — no additional DOM rebuilds

Kpa-clawbot 4b8d8143f4 feat(server): explicit CORS policy with configurable origin allowlist (#883) (#971)
## Summary

Adds explicit CORS policy support to the CoreScope API server, closing
#883.

### Problem

The API relied on browser same-origin defaults with no way for operators
to configure cross-origin access. Operators running dashboards or
third-party frontends on different origins had no supported way to make
API calls.

### Solution

**New config option:** `corsAllowedOrigins` (string array, default `[]`)

**Middleware behavior:**
| Config | Behavior |
|--------|----------|
| `[]` (default) | No `Access-Control-*` headers added — browsers
enforce same-origin. **Preserves current behavior.** |
| `["https://dashboard.example.com"]` | Echoes matching `Origin`, sets
`Allow-Methods`/`Allow-Headers` |
| `["*"]` | Sets `Access-Control-Allow-Origin: *` (explicit opt-in only)
|

**Headers set when origin matches:**
- `Access-Control-Allow-Origin: <origin>` (or `*`)
- `Access-Control-Allow-Methods: GET, POST, OPTIONS`
- `Access-Control-Allow-Headers: Content-Type, X-API-Key`
- `Vary: Origin` (non-wildcard only)

**Preflight handling:** `OPTIONS` → `204 No Content` with CORS headers
(or `403` if origin not in allowlist).

### Config example

```json
{
  "corsAllowedOrigins": ["https://dashboard.example.com", "https://monitor.internal"]
}
```

### Files changed

| File | Change |
|------|--------|
| `cmd/server/cors.go` | New CORS middleware |
| `cmd/server/cors_test.go` | 7 unit tests covering all branches |
| `cmd/server/config.go` | `CORSAllowedOrigins` field |
| `cmd/server/routes.go` | Wire middleware before all routes |

### Testing

**Unit tests (7):**
- Default config → no CORS headers
- Allowlist match → headers present with `Vary: Origin`
- Allowlist miss → no CORS headers
- Preflight allowed → 204 with headers
- Preflight rejected → 403
- Wildcard → `*` without `Vary`
- No `Origin` header → pass-through

**Live verification (Rule 18):**

```
# Default (empty corsAllowedOrigins):
$ curl -I -H "Origin: https://evil.example" localhost:19883/api/health
HTTP/1.1 200 OK
# No Access-Control-* headers ✓

# With corsAllowedOrigins: ["https://good.example"]:
$ curl -I -H "Origin: https://good.example" localhost:19884/api/health
Access-Control-Allow-Origin: https://good.example
Access-Control-Allow-Methods: GET, POST, OPTIONS
Access-Control-Allow-Headers: Content-Type, X-API-Key
Vary: Origin ✓

$ curl -I -H "Origin: https://evil.example" localhost:19884/api/health
# No Access-Control-* headers ✓

$ curl -I -X OPTIONS -H "Origin: https://good.example" localhost:19884/api/health
HTTP/1.1 204 No Content
Access-Control-Allow-Origin: https://good.example ✓
```

Kpa-clawbot 3364eed303 feat: separate "Last Status Update" from "Last Packet Observation" for observers (v3 rebase) (#969)
Rebased version of #968 (which was itself a rebase of #905) — resolves
merge conflict with #906 (clock-skew UI) that landed on master.

## Conflict resolution

**`public/observers.js`** — master (#906) added "Clock Offset" column to
observer table; #968 split "Last Seen" into "Last Status" + "Last
Packet" columns. Combined both: the table now has Status | Name | Region
| Last Status | Last Packet | Packets | Packets/Hour | Clock Offset |
Uptime.

## What this PR adds (unchanged from #968/#905)

- `last_packet_at` column in observers DB table
- Separate "Last Status Update" and "Last Packet Observation" display in
observers list and detail page
- Server-side migration to add the column automatically
- Backfill heuristic for existing data
- Tests for ingestor and server

## Verification

- All Go tests pass (`cmd/server`, `cmd/ingestor`)
- Frontend tests pass (`test-packets.js`, `test-hash-color.js`)
- Built server, hit `/api/observers` — `last_packet_at` field present in
JSON
- Observer table header has all 9 columns including both Last Packet and
Clock Offset

## Prior PRs

- #905 — original (conflicts with master)
- #968 — first rebase (conflicts after #906 landed)
- This PR — second rebase, resolves #906 conflict

Supersedes #968. Closes #905.

efiten 40c3aa13f9 fix(paths): exclude false-positive paths from short-prefix collisions (#930)
Fixes #929

## Summary

- `handleNodePaths` pulls candidates from `byPathHop` using 2-char and
4-char prefix keys (e.g. `"7a"` for a node using 1-byte adverts)
- When two nodes share the same short prefix, paths through the *other*
node are included as candidates
- The `resolved_path` post-filter covers decoded packets but falls
through conservatively (`inIndex = true`) when `resolved_path` is NULL,
letting false positives reach the response

**Fix:** during the aggregation phase (which already calls `resolveHop`
per hop), add a `containsTarget` check. If every hop resolves to a
different node's pubkey, skip the path. Packets confirmed via the
full-pubkey index key or via SQL bypass the check. Unresolvable hops are
kept conservatively.

## Test plan
- [x] `TestHandleNodePaths_PrefixCollisionExclusion`: two nodes sharing
`"7a"` prefix; verifies the path with no `resolved_path` (false
positive) is excluded and the SQL-confirmed path (true positive) is
included
- [x] Full test suite: `go test github.com/corescope/server` — all pass

Kpa-clawbot b3a9677c52 feat(ingestor + server): observerBlacklist config (#962) (#963)
## Summary

Implements `observerBlacklist` config — mirrors the existing
`nodeBlacklist` pattern for observers. Drop observers by pubkey at
ingest, with defense-in-depth filtering on the server side.

Closes #962

## Changes

### Ingestor (`cmd/ingestor/`)
- **`config.go`**: Added `ObserverBlacklist []string` field +
`IsObserverBlacklisted()` method (case-insensitive, whitespace-trimmed)
- **`main.go`**: Early return in `handleMessage` when `parts[2]`
(observer ID from MQTT topic) matches blacklist — before status
handling, before IATA filter. No UpsertObserver, no observations, no
metrics insert. Log line: `observer <pubkey-short> blacklisted,
dropping`

### Server (`cmd/server/`)
- **`config.go`**: Same `ObserverBlacklist` field +
`IsObserverBlacklisted()` with `sync.Once` cached set (same pattern as
`nodeBlacklist`)
- **`routes.go`**: Defense-in-depth filtering in `handleObservers` (skip
blacklisted in list) and `handleObserverDetail` (404 for blacklisted ID)
- **`main.go`**: Startup `softDeleteBlacklistedObservers()` marks
matching rows `inactive=1` so historical data is hidden
- **`neighbor_persist.go`**: `softDeleteBlacklistedObservers()`
implementation

### Tests
- `cmd/ingestor/observer_blacklist_test.go`: config method tests
(case-insensitive, empty, nil)
- `cmd/server/observer_blacklist_test.go`: config tests + HTTP handler
tests (list excludes blacklisted, detail returns 404, no-blacklist
passes all, concurrent safety)

## Config

```json
{
  "observerBlacklist": [
    "EE550DE547D7B94848A952C98F585881FCF946A128E72905E95517475F83CFB1"
  ]
}
```

## Verification (Rule 18 — actual server output)

**Before blacklist** (no config):
```
Total: 31
DUBLIN in list: True
```

**After blacklist** (DUBLIN Observer pubkey in `observerBlacklist`):
```
[observer-blacklist] soft-deleted 1 blacklisted observer(s)
Total: 30
DUBLIN in list: False
```

Detail endpoint for blacklisted observer returns **404**.

All existing tests pass (`go test ./...` for both server and ingestor).

Kpa-clawbot 57e272494d feat(server): /api/healthz readiness endpoint gated on store load (#955) (#956)
## Summary

Fixes RCA #2 from #955: the HTTP listener and `/api/stats` go live
before background goroutines (pickBestObservation, neighbor graph build)
finish, causing CI readiness checks to pass prematurely.

## Changes

1. **`cmd/server/healthz.go`** — New `GET /api/healthz` endpoint:
- Returns `503 {"ready":false,"reason":"loading"}` while background init
is running
   - Returns `200 {"ready":true,"loadedTx":N,"loadedObs":N}` once ready

2. **`cmd/server/main.go`** — Added `sync.WaitGroup` tracking
pickBestObservation and neighbor graph build goroutines. A coordinator
goroutine sets `readiness.Store(1)` when all complete.
`backfillResolvedPathsAsync` is NOT gated (async by design, can take 20+
min).

3. **`cmd/server/routes.go`** — Wired `/api/healthz` before system
endpoints.

4. **`.github/workflows/deploy.yml`** — CI wait-for-ready loop now polls
`/api/healthz` instead of `/api/stats`.

5. **`cmd/server/healthz_test.go`** — Tests for 503-before-ready,
200-after-ready, JSON shape, and anti-tautology gate.

## Rule 18 Verification

Built and ran against `test-fixtures/e2e-fixture.db` (499 tx):
- With the small fixture DB, init completes in <300ms so both immediate
and delayed curls return 200
- Unit tests confirm 503 behavior when `readiness=0` (simulating slow
init)
- On production DBs with 100K+ txs, the 503 window would be 5-15s
(pickBestObservation processes in 5000-tx chunks with 10ms yields)

## Test Results

```
=== RUN   TestHealthzNotReady    --- PASS
=== RUN   TestHealthzReady       --- PASS  
=== RUN   TestHealthzAntiTautology --- PASS
ok  github.com/corescope/server  19.662s (full suite)

Kpa-clawbot 54f7f9d35b feat: path-prefix candidate inspector with map view (#944) (#945)
## feat: path-prefix candidate inspector with map view (#944)

Implements the locked spec from #944: a beam-search-based path prefix
inspector that enumerates candidate full-pubkey paths from short hex
prefixes and scores them.

### Server (`cmd/server/path_inspect.go`)

- **`POST /api/paths/inspect`** — accepts 1-64 hex prefixes (1-3 bytes,
uniform length per request)
- Beam search (width 20) over cached `prefixMap` + `NeighborGraph`
- Per-hop scoring: edge weight (35%), GPS plausibility (20%), recency
(15%), prefix selectivity (30%)
- Geometric mean aggregation with 0.05 floor per hop
- Speculative threshold: score < 0.7
- Score cache: 30s TTL, keyed by (prefixes, observer, window)
- Cold-start: synchronous NeighborGraph rebuild with 2s hard timeout →
503 `{retry:true}`
- Body limit: 4096 bytes via `http.MaxBytesReader`
- Zero SQL queries in handler hot path
- Request validation: rejects empty, odd-length, >3 bytes, mixed
lengths, >64 hops

### Frontend (`public/path-inspector.js`)

- New page under Tools route with input field (comma/space separated hex
prefixes)
- Client-side validation with error feedback
- Results table: rank, score (color-coded speculative), path names,
per-hop evidence (collapsed)
- "Show on Map" button calls `drawPacketRoute` (one path at a time,
clears prior)
- Deep link: `#/tools/path-inspector?prefixes=2c,a1,f4`

### Nav reorganization

- `Traces` nav item renamed to `Tools`
- Backward-compat: `#/traces/<hash>` redirects to `#/tools/trace/<hash>`
- Tools sub-routing dispatches to traces or path-inspector

### Store changes

- Added `LastSeen time.Time` to `nodeInfo` struct, populated from
`nodes.last_seen`
- Added `inspectMu` + `inspectCache` fields to `PacketStore`

### Tests

- **Go unit tests** (`path_inspect_test.go`): scoreHop components, beam
width cap, speculative flag, all validation error cases, valid request
integration
- **Frontend tests** (`test-path-inspector.js`): parse
comma/space/mixed, validation (empty, odd, >3 bytes, mixed lengths,
invalid hex, valid)
- Anti-tautology gate verified: removing beam pruning fails width test;
removing validation fails reject tests

### CSS

- `--path-inspector-speculative` variable in both themes (amber, WCAG AA
on both dark/light backgrounds)
- All colors via CSS variables (no hardcoded hex in production code)

Closes #944

Kpa-clawbot 6ca5e86df6 fix: compute hex-dump byte ranges client-side from per-obs raw_hex (#891)
## Symptom
The colored byte strip in the packet detail pane is offset from the
labeled byte breakdown below it. Off by N bytes where N is the
difference between the top-level packet's path length and the displayed
observation's path length.

## Root cause
Server computes `breakdown.ranges` once from the top-level packet's
raw_hex (in `BuildBreakdown`) and ships it in the API response. After
#882 we render each observation's own raw_hex, but we keep using the
top-level breakdown — so a 7-hop top-level packet shipped "Path: bytes
2-8", and when we rendered an 8-hop observation we coloured 7 of the 8
path bytes and bled into the payload.

The labeled rows below (which use `buildFieldTable`) parse the displayed
raw_hex on the client, so they were correct — they just didn't match the
strip above.

## Fix
Port `BuildBreakdown()` to JS as `computeBreakdownRanges()` in `app.js`.
Use it in `renderDetail()` from the actually-rendered (per-obs) raw_hex.

## Test
Manually verified the JS function output matches the Go implementation
for FLOOD/non-transport, transport, ADVERT, and direct-advert (zero
hops) cases.

Closes nothing (caught in post-tag bug bash).

Kpa-clawbot 56ec590bc4 fix(#886): derive path_json from raw_hex at ingest (#887)
## Problem

Per-observation `path_json` disagrees with `raw_hex` path section for
TRACE packets.

**Reproducer:** packet `af081a2c41281b1e`, observer `lutin🏡`
- `path_json`: `["67","33","D6","33","67"]` (5 hops — from TRACE
payload)
- `raw_hex` path section: `30 2D 0D 23` (4 bytes — SNR values in header)

## Root Cause

`DecodePacket` correctly parses TRACE packets by replacing `path.Hops`
with hop IDs from the payload's `pathData` field (the actual route).
However, the header path bytes for TRACE packets contain **SNR values**
(one per completed hop), not hop IDs.

`BuildPacketData` used `decoded.Path.Hops` to build `path_json`, which
for TRACE packets contained the payload-derived hops — not the header
path bytes that `raw_hex` stores. This caused `path_json` and `raw_hex`
to describe completely different paths.

## Fix

- Added `DecodePathFromRawHex(rawHex)` — extracts header path hops
directly from raw hex bytes, independent of any TRACE payload
overwriting.
- `BuildPacketData` now calls `DecodePathFromRawHex(msg.Raw)` instead of
using `decoded.Path.Hops`, guaranteeing `path_json` always matches the
`raw_hex` path section.

## Tests (8 new)

**`DecodePathFromRawHex` unit tests:**
- hash_size 1, 2, 3, 4
- zero-hop direct packets
- transport route (4-byte transport codes before path)

**`BuildPacketData` integration tests:**
- TRACE packet: asserts path_json matches raw_hex header path (not
payload hops)
- Non-TRACE packet: asserts path_json matches raw_hex header path

All existing tests continue to pass (`go test ./...` for both ingestor
and server).

Fixes #886

Kpa-clawbot 42ff5a291b fix(#866): full-page obs-switch — update hex + path + direction per observation (#870)
## Problem

On `/#/packets/<hash>?obs=<id>`, clicking a different observation
updated summary fields (Observer, SNR/RSSI, Timestamp) but **not** hex
payload or path details. Sister bug to #849 (fixed in #851 for the
detail dialog).

## Root Causes

| Cause | Impact |
|-------|--------|
| `selectPacket` called `renderDetail` without `selectedObservationId` |
Initial render missed observation context on some code paths |
| `ObservationResp` missing `direction`, `resolved_path`, `raw_hex` |
Frontend obs-switch lost direction and resolved_path context |
| `obsPacket` construction omitted `direction` field | Direction not
preserved when switching observations |

## Fix

- `selectPacket` explicitly passes `selectedObservationId` to
`renderDetail`
- `ObservationResp` gains `Direction`, `ResolvedPath`, `RawHex` fields
- `mapSliceToObservations` copies the three new fields
- `obsPacket` spreads include `direction` from the observation

## Tests

7 new tests in `test-frontend-helpers.js`:
- Observation switch updates `effectivePkt` path
- `raw_hex` preserved from packet when obs has none
- `raw_hex` from obs overrides when API provides it
- `direction` carried through observation spread
- `resolved_path` carried through observation spread
- `getPathLenOffset` cross-check for transport routes
- URL hash `?obs=` round-trip encoding

All 584 frontend + 62 filter + 29 aging tests pass. Go server tests
pass.

Kpa-clawbot 3f26dc7190 obs: surface real RSS alongside tracked store bytes in /api/stats (#832) (#835)
Closes #832.

## Root cause confirmed
\`trackedMB\` (\`s.trackedBytes\` in \`store.go\`) only sums per-packet
struct + payload sizes recorded at insertion. It excludes the index maps
(\`byHash\`, \`byTxID\`, \`byNode\`, \`byObserver\`, \`byPathHop\`,
\`byPayloadType\`, hash-prefix maps, name lookups), the analytics LRUs
(rfCache/topoCache/hashCache/distCache/subpathCache/chanCache/collisionCache),
WS broadcast queues, and Go runtime overhead. It's \"useful packet
bytes,\" not RSS — typically 3–5× off on staging.

## Fix (Option C from the issue)
Expose four memory fields on \`/api/stats\` from a single cached
snapshot:

| Field | Source | Semantics |
|---|---|---|
| \`storeDataMB\` | \`s.trackedBytes\` | in-store packet bytes; eviction
watermark input |
| \`goHeapInuseMB\` | \`runtime.MemStats.HeapInuse\` | live Go heap |
| \`goSysMB\` | \`runtime.MemStats.Sys\` | total Go-managed memory |
| \`processRSSMB\` | \`/proc/self/status VmRSS\` (Linux), falls back to
\`goSysMB\` | what the kernel sees |

\`trackedMB\` is retained as a deprecated alias for \`storeDataMB\` so
existing dashboards/QA scripts keep working.

Field invariants are documented on \`MemorySnapshot\`: \`processRSSMB ≥
goSysMB ≥ goHeapInuseMB ≥ storeDataMB\` (typical).

## Performance
Single \`getMemorySnapshot\` call cached for 1s —
\`runtime.ReadMemStats\` (stop-the-world) and the \`/proc/self/status\`
read are amortized across burst polling. \`/proc\` read is bounded to 8
KiB, parsed with \`strconv\` only — no shell-out, no untrusted input.

\`cgoBytesMB\` is omitted: the build uses pure-Go
\`modernc.org/sqlite\`, so there is no cgo allocator to measure.
Documented in code comment.

## Tests
\`cmd/server/stats_memory_test.go\` asserts presence, types, sign, and
ordering invariants. Avoids the flaky \"matches RSS to ±X%\" pattern.

\`\`\`
$ go test ./... -count=1 -timeout 180s
ok  	github.com/corescope/server	19.410s
\`\`\`

## QA plan
§1.4 now compares \`processRSSMB\` against procfs RSS (the right
invariant); threshold stays at 0.20.

Kpa-clawbot 886aabf0ae fix(#827): /api/packets/{hash} falls back to DB when in-memory store misses (#831)
Closes #827.

## Problem
`/api/packets/{hash}` only consulted the in-memory `PacketStore`. When a
packet aged out of memory, the handler 404'd — even though SQLite still
had it and `/api/nodes/{pubkey}` `recentAdverts` (which reads from the
DB) was actively surfacing the hash. Net effect: the **Analyze →** link
on older adverts in the node detail page led to a dead "Not found".

Two-store inconsistency: DB has the packet, in-memory doesn't, node
detail surfaces it from DB → packet detail can't serve it.

## Fix
In `handlePacketDetail`:
- After in-memory miss, fall back to `db.GetPacketByHash` (already
existed) for hash lookups, and `db.GetTransmissionByID` for numeric IDs.
- Track when the result came from the DB; if so and the store has no
observations, populate from DB via a new `db.GetObservationsForHash` so
the response shows real observations instead of the misleading
`observation_count = 1` fallback.

## Tests
- `TestPacketDetailFallsBackToDBWhenStoreMisses` — insert a packet
directly into the DB after `store.Load()`, confirm store doesn't have
it, assert 200 + populated observations.
- `TestPacketDetail404WhenAbsentFromBoth` — neither store nor DB → 404
(no false positives).
- `TestPacketDetailPrefersStoreOverDB` — both have it; store result wins
(no double-fetch).
- `TestHandlePacketDetailNoStore` updated: it previously asserted the
old buggy 404 behavior; now asserts the correct DB-fallback 200.

All `go test ./... -run "PacketDetail|Packet|GetPacket"` and the full
`cmd/server` suite pass.

## Out of scope
The `/api/packets?hash=` filter is the live in-memory list endpoint and
intentionally store-only for performance. Not touched here — happy to
file a follow-up if you'd rather harmonise.

## Repro context
Verified against prod with a recently-adverting repeater whose recent
advert hash lives in `recentAdverts` (DB) but had been evicted from the
in-memory store; pre-fix 404, post-fix 200 with full observations.

Kpa-clawbot d7fe24e2db Fix channel filter on Packets page (UI + API) — #812 (#816)
Closes #812

## Root causes

**Server (`/api/packets?channel=…` returned identical totals):**
The handler in `cmd/server/routes.go` never read the `channel` query
parameter into `PacketQuery`, so it was silently ignored by both the
SQLite path (`db.go::buildTransmissionWhere`) and the in-memory path
(`store.go::filterPackets`). The codebase already had everything else in
place — the `channel_hash` column with an index from #762, decoded
`channel` / `channelHashHex` fields on each packet — it just wasn't
wired up.

**UI (`/#/packets` had no channel filter):**
`public/packets.js` rendered observer / type / time-window / region
filters but no channel control, and didn't read `?channel=` from the
URL.

## Fix

### Server
- New `Channel` field on `PacketQuery`; `handlePackets` reads
`r.URL.Query().Get("channel")`.
- DB path filters by the indexed `channel_hash` column (exact match).
- In-memory path: helper `packetMatchesChannel` matches
`decoded.channel` (plaintext, e.g. `#test`, `public`) or `enc_<HEX>`
against `channelHashHex` for undecryptable GRP_TXT. Uses cached
`ParsedDecoded()` so it's O(1) after first parse. Fast-path index guards
and the grouped-cache key updated to include channel.
- Regression test (`channel_filter_test.go`): `channel=#test` returns ≥1
GRP_TXT packet and fewer than baseline; `channel=nonexistentchannel`
returns `total=0`.

### UI
- New `<select id="fChannel">` populated from `/api/channels`.
- Round-trips via `?channel=…` on the URL hash (read on init, written on
change).
- Pre-seeds the current value as an option so encrypted hashes not in
`/api/channels` still display as selected on reload.
- On change, calls `loadPackets()` so the server-side filter applies
before pagination.

## Perf

Filter adds at most one cached map lookup per packet (DB path uses
indexed column, store path uses `ParsedDecoded()` cache). Staging
baseline 149–190 ms for `?channel=#test&limit=50`; the new comparison is
negligible. Target ≤ 500 ms preserved.

## Tests
`cd cmd/server && go test ./... -count=1 -timeout 120s` → PASS.

Kpa-clawbot 9e90548637 perf(#800): remove per-StoreTx ResolvedPath, replace with membership index + on-demand decode (#806)
## Summary

Remove `ResolvedPath []*string` field from `StoreTx` and `StoreObs`
structs, replacing it with a compact membership index + on-demand SQL
decode. This eliminates the dominant heap cost identified in profiling
(#791, #799).

**Spec:** #800 (consolidated from two rounds of expert + implementer
review on #799)

Closes #800
Closes #791

## Design

### Removed
- `StoreTx.ResolvedPath []*string`
- `StoreObs.ResolvedPath []*string`
- `TransmissionResp.ResolvedPath`, `ObservationResp.ResolvedPath` struct
fields

### Added
| Structure | Purpose | Est. cost at 1M obs |
|---|---|---:|
| `resolvedPubkeyIndex map[uint64][]int` | FNV-1a(pubkey) → []txID
forward index | 50–120 MB |
| `resolvedPubkeyReverse map[int][]uint64` | txID → []hashes for clean
removal | ~40 MB |
| `apiResolvedPathLRU` (10K entries) | FIFO cache for on-demand API
decode | ~2 MB |

### Decode-window discipline
`resolved_path` JSON decoded once per packet. Consumers fed in order,
temp slice dropped — never stored on struct:
1. `addToByNode` — relay node indexing
2. `touchRelayLastSeen` — relay liveness DB updates
3. `byPathHop` resolved-key entries
4. `resolvedPubkeyIndex` + reverse insert
5. WebSocket broadcast map (raw JSON bytes)
6. Persist batch (raw JSON bytes for SQL UPDATE)

### Collision safety
When the forward index returns candidates, a batched SQL query confirms
exact pubkey presence using `LIKE '%"pubkey"%'` on the `resolved_path`
column.

### Feature flag
`useResolvedPathIndex` (default `true`). Off-path is conservative: all
candidates kept, index not consulted. For one-release rollback safety.

## Files changed

| File | Changes |
|---|---|
| `resolved_index.go` | **New** — index structures, LRU cache, on-demand
SQL helpers, collision safety |
| `store.go` | Remove RP fields, decode-window discipline in
Load/Ingest, on-demand txToMap/obsToMap/enrichObs, eviction cleanup via
SQL, memory accounting update |
| `types.go` | Remove RP fields from TransmissionResp/ObservationResp |
| `routes.go` | Replace `nodeInResolvedPath` with
`nodeInResolvedPathViaIndex`, remove RP from mapSlice helpers |
| `neighbor_persist.go` | Refactor backfill: reverse-map removal →
forward+reverse insert → LRU invalidation |

## Tests added (27 new)

**Unit:**
- `TestStoreTx_ResolvedPathFieldAbsent` — reflection guard
- `TestResolvedPubkeyIndex_BuildFromLoad` — forward+reverse consistency
- `TestResolvedPubkeyIndex_HashCollision` — SQL collision safety
- `TestResolvedPubkeyIndex_IngestUpdate` — maps reflect new ingests
- `TestResolvedPubkeyIndex_RemoveOnEvict` — clean removal via reverse
map
- `TestResolvedPubkeyIndex_PerObsCoverage` — non-best obs pubkeys
indexed
- `TestAddToByNode_WithoutResolvedPathField`
- `TestTouchRelayLastSeen_WithoutResolvedPathField`
- `TestWebSocketBroadcast_IncludesResolvedPath`
- `TestBackfill_InvalidatesLRU`
- `TestEviction_ByNodeCleanup_OnDemandSQL`
- `TestExtractResolvedPubkeys`, `TestMergeResolvedPubkeys`
- `TestResolvedPubkeyHash_Deterministic`
- `TestLRU_EvictionOnFull`

**Endpoint:**
- `TestPathsThroughNode_NilResolvedPathFallback`
- `TestPacketsAPI_OnDemandResolvedPath`
- `TestPacketsAPI_OnDemandResolvedPath_LRUHit`
- `TestPacketsAPI_OnDemandResolvedPath_Empty`

**Feature flag:**
- `TestFeatureFlag_OffPath_PreservesOldBehavior`
- `TestFeatureFlag_Toggle_NoStateLeak`

**Concurrency:**
- `TestReverseMap_NoLeakOnPartialFailure`
- `TestDecodeWindow_LockHoldTimeBounded`
- `TestLivePolling_LRUUnderConcurrentIngest`

**Regression:**
- `TestRepeaterLiveness_StillAccurate`

**Benchmarks:**
- `BenchmarkLoad_BeforeAfter`
- `BenchmarkResolvedPubkeyIndex_Memory`
- `BenchmarkPathsThroughNode_Latency`
- `BenchmarkLivePolling_UnderIngest`

## Benchmark results

```
BenchmarkResolvedPubkeyIndex_Memory/pubkeys=50K     429ms  103MB   777K allocs
BenchmarkResolvedPubkeyIndex_Memory/pubkeys=500K   4205ms  896MB  7.67M allocs
BenchmarkLoad_BeforeAfter                            65ms   20MB   202K allocs
BenchmarkPathsThroughNode_Latency                   3.9µs    0B      0 allocs
BenchmarkLivePolling_UnderIngest                    5.4µs  545B      7 allocs
```

Key: per-obs `[]*string` overhead completely eliminated. At 1M obs with
3 hops average, this saves ~72 bytes/obs × 1M = ~68 MB just from the
slice headers + pointers, plus the JSON-decoded string data (~900 MB at
scale per profiling).

## Design choices

- **FNV-1a instead of xxhash**: stdlib availability, no external
dependency. Performance is equivalent for this use case (pubkey strings
are short).
- **FIFO LRU instead of true LRU**: simpler implementation, adequate for
the access pattern (mostly sequential obs IDs from live polling).
- **Grouped packets view omits resolved_path**: cold path, not worth SQL
round-trip per page render.
- **Backfill pending check uses reverse-map presence** instead of
per-obs field: if a tx has any indexed pubkeys, its observations are
considered resolved.

Kpa-clawbot a8e1cea683 fix: use payload type bits only in content hash (not full header byte) (#787)
## Problem

The firmware computes packet content hash as:

```
SHA256(payload_type_byte + [path_len for TRACE] + payload)
```

Where `payload_type_byte = (header >> 2) & 0x0F` — just the payload type
bits (2-5).

CoreScope was using the **full header byte** in its hash computation,
which includes route type bits (0-1) and version bits (6-7). This meant
the same logical packet produced different content hashes depending on
route type — breaking dedup and packet lookup.

**Firmware reference:** `Packet.cpp::calculatePacketHash()` uses
`getPayloadType()` which returns `(header >> PH_TYPE_SHIFT) &
PH_TYPE_MASK`.

## Fix

- Extract only payload type bits: `payloadType := (headerByte >> 2) &
0x0F`
- Include `path_len` byte in hash for TRACE packets (matching firmware
behavior)
- Applied to both `cmd/server/decoder.go` and `cmd/ingestor/decoder.go`

## Tests Added

- **Route type independence:** Same payload with FLOOD vs DIRECT route
types produces identical hash
- **TRACE path_len inclusion:** TRACE packets with different `path_len`
produce different hashes
- **Firmware compatibility:** Hash output matches manual computation of
firmware algorithm

## Migration Impact

Existing packets in the DB have content hashes computed with the old
(incorrect) formula. Options:

1. **Recompute hashes** via migration (recommended for clean state)
2. **Dual lookup** — check both old and new hash on queries (backward
compat)
3. **Accept the break** — old hashes become stale, new packets get
correct hashes

Recommend option 1 (migration) as a follow-up. The volume of affected
packets depends on how many distinct route types were seen for the same
logical packet.

Kpa-clawbot bf674ebfa2 feat: validate advert signatures on ingest, reject corrupt packets (#794)
## Summary

Validates ed25519 signatures on ADVERT packets during MQTT ingest.
Packets with invalid signatures are rejected before storage, preventing
corrupt/truncated adverts from polluting the database.

## Changes

### Ingestor (`cmd/ingestor/`)

- **Signature validation on ingest**: After decoding an ADVERT, checks
`SignatureValid` from the decoder. Invalid signatures → packet dropped,
never stored.
- **Config flag**: `validateSignatures` (default `true`). Set to `false`
to disable validation for backward compatibility with existing installs.
- **`dropped_packets` table**: New SQLite table recording every rejected
packet with full attribution:
- `hash`, `raw_hex`, `reason`, `observer_id`, `observer_name`,
`node_pubkey`, `node_name`, `dropped_at`
  - Indexed on `observer_id` and `node_pubkey` for investigation queries
- **`SignatureDrops` counter**: New atomic counter in `DBStats`, logged
in periodic stats output as `sig_drops=N`
- **Retention**: `dropped_packets` pruned alongside metrics on the same
`retention.metricsDays` schedule

### Server (`cmd/server/`)

- **`GET /api/dropped-packets`** (API key required): Returns recent
drops with optional `?observer=` and `?pubkey=` filters, `?limit=`
(default 100, max 500)
- **`signatureDrops`** field added to `/api/stats` response (count from
`dropped_packets` table)

### Tests (8 new)

| Test | What it verifies |
|------|-----------------|
| `TestSigValidation_ValidAdvertStored` | Valid advert passes validation
and is stored |
| `TestSigValidation_TamperedSignatureDropped` | Tampered signature →
dropped, recorded in `dropped_packets` with correct fields |
| `TestSigValidation_TruncatedAppdataDropped` | Truncated appdata
invalidates signature → dropped |
| `TestSigValidation_DisabledByConfig` | `validateSignatures: false`
skips validation, stores tampered packet |
| `TestSigValidation_DropCounterIncrements` | Counter increments
correctly across multiple drops |
| `TestSigValidation_LogContainsFields` | `dropped_packets` row contains
hash, reason, observer, pubkey, name |
| `TestPruneDroppedPackets` | Old entries pruned, recent entries
retained |
| `TestShouldValidateSignatures_Default` | Config helper returns correct
defaults |

### Config example

```json
{
  "validateSignatures": true
}
```

Joel Claw b9ba447046 feat: add nodeBlacklist config to hide abusive/troll nodes (#742)
## Problem

Some mesh participants set offensive names, report deliberately false
GPS positions, or otherwise troll the network. Instance operators
currently have no way to hide these nodes from public-facing APIs
without deleting the underlying data.

## Solution

Add a `nodeBlacklist` array to `config.json` containing public keys of
nodes to exclude from all API responses.

### Blacklisted nodes are filtered from:

- `GET /api/nodes` — list endpoint
- `GET /api/nodes/search` — search results
- `GET /api/nodes/{pubkey}` — detail (returns 404)
- `GET /api/nodes/{pubkey}/health` — returns 404
- `GET /api/nodes/{pubkey}/paths` — returns 404
- `GET /api/nodes/{pubkey}/analytics` — returns 404
- `GET /api/nodes/{pubkey}/neighbors` — returns 404
- `GET /api/nodes/bulk-health` — filtered from results

### Config example

```json
{
  "nodeBlacklist": [
    "aabbccdd...",
    "11223344..."
  ]
}
```

### Design decisions

- **Case-insensitive** — public keys normalized to lowercase
- **Whitespace trimming** — leading/trailing whitespace handled
- **Empty entries ignored** — `""` or `" "` do not cause false positives
- **Nil-safe** — `IsBlacklisted()` on nil Config returns false
- **Backward-compatible** — empty/missing `nodeBlacklist` has zero
effect
- **Lazy-cached set** — blacklist converted to `map[string]bool` on
first lookup

### What this does NOT do (intentionally)

- Does **not** delete or modify database data — only filters API
responses
- Does **not** block packet ingestion — data still flows for analytics
- Does **not** filter `/api/packets` — only node-facing endpoints are
affected

## Testing

- Unit tests for `Config.IsBlacklisted()` (case sensitivity, whitespace,
empty entries, nil config)
- Integration tests for `/api/nodes`, `/api/nodes/{pubkey}`,
`/api/nodes/search`
- Full test suite passes with no regressions

Joel Claw fa3f623bd6 feat: add observer retention — remove stale observers after configurable days (#764)
## Summary

Observers that stop actively sending data now get removed after a
configurable retention period (default 14 days).

Previously, observers remained in the `observers` table forever. This
meant nodes that were once observers for an instance but are no longer
connected (even if still active in the mesh elsewhere) would continue
appearing in the observer list indefinitely.

## Key Design Decisions

- **Active data requirement**: `last_seen` is only updated when the
observer itself sends packets (via `stmtUpdateObserverLastSeen`). Being
seen by another node does NOT update this field. So an observer must
actively send data to stay listed.
- **Default: 14 days** — observers not seen in 14 days are removed
- **`-1` = keep forever** — for users who want observers to never be
removed
- **`0` = use default (14 days)** — same as not setting the field
- **Runs on startup + daily ticker** — staggered 3 minutes after metrics
prune to avoid DB contention

## Changes

| File | Change |
|------|--------|
| `cmd/ingestor/config.go` | Add `ObserverDays` to `RetentionConfig`,
add `ObserverDaysOrDefault()` |
| `cmd/ingestor/db.go` | Add `RemoveStaleObservers()` — deletes
observers with `last_seen` before cutoff |
| `cmd/ingestor/main.go` | Wire up startup + daily ticker for observer
retention |
| `cmd/server/config.go` | Add `ObserverDays` to `RetentionConfig`, add
`ObserverDaysOrDefault()` |
| `cmd/server/db.go` | Add `RemoveStaleObservers()` (server-side, uses
read-write connection) |
| `cmd/server/main.go` | Wire up startup + daily ticker, shutdown
cleanup |
| `cmd/server/routes.go` | Admin prune API now also removes stale
observers |
| `config.example.json` | Add `observerDays: 14` with documentation |
| `cmd/ingestor/coverage_boost_test.go` | 4 tests: basic removal, empty
store, keep forever (-1), default (0→14) |
| `cmd/server/config_test.go` | 4 tests: `ObserverDaysOrDefault` edge
cases |

## Config Example

```json
{
  "retention": {
    "nodeDays": 7,
    "observerDays": 14,
    "packetDays": 30,
    "_comment": "observerDays: -1 = keep forever, 0 = use default (14)"
  }
}
```

## Admin API

The `/api/admin/prune` endpoint now also removes stale observers (using
`observerDays` from config) and reports `observers_removed` in the
response alongside `packets_deleted`.

## Test Plan

- [x] `TestRemoveStaleObservers` — old observer removed, recent observer
kept
- [x] `TestRemoveStaleObserversNone` — empty store, no errors
- [x] `TestRemoveStaleObserversKeepForever` — `-1` keeps even year-old
observers
- [x] `TestRemoveStaleObserversDefault` — `0` defaults to 14 days
- [x] `TestObserverDaysOrDefault` (ingestor) —
nil/zero/positive/keep-forever

Kpa-clawbot a815e70975 feat: Clock skew detection — backend computation (M1) (#746)
## Summary

Implements **Milestone 1** of #690 — backend clock skew computation for
nodes and observers.

## What's New

### Clock Skew Engine (`clock_skew.go`)

**Phase 1 — Raw Skew Calculation:**
For every ADVERT observation: `raw_skew = advert_timestamp -
observation_timestamp`

**Phase 2 — Observer Calibration:**
Same packet seen by multiple observers → compute each observer's clock
offset as the median deviation from the per-packet median observation
timestamp. This identifies observers with their own clock drift.

**Phase 3 — Corrected Node Skew:**
`corrected_skew = raw_skew + observer_offset` — compensates for observer
clock error.

**Phase 4 — Trend Analysis:**
Linear regression over time-ordered skew samples estimates drift rate in
seconds/day. Detects crystal drift vs stable offset vs sudden jumps.

### Severity Classification

| Level | Threshold | Meaning |
|-------|-----------|---------|
|  OK | < 5 min | Normal |
| ⚠️ Warning | 5 min – 1 hour | Clock drifting |
| 🔴 Critical | 1 hour – 30 days | Likely no time source |
| 🟣 Absurd | > 30 days | Firmware default or epoch 0 |

### New API Endpoints

- `GET /api/nodes/{pubkey}/clock-skew` — per-node skew data (mean,
median, last, drift, severity)
- `GET /api/observers/clock-skew` — observer calibration offsets
- Clock skew also included in `GET /api/nodes/{pubkey}/analytics`
response as `clockSkew` field

### Performance

- 30-second compute cache avoids reprocessing on every request
- Operates on in-memory `byPayloadType[ADVERT]` index — no DB queries
- O(n) in total ADVERT observations, O(m log m) for median calculations

## Tests

15 unit tests covering:
- Severity classification at all thresholds
- Median/mean math helpers
- ISO timestamp parsing
- Timestamp extraction from decoded JSON (nested and top-level)
- Observer calibration with single and multi-observer scenarios
- Observer offset correction direction (verified the sign is
`+obsOffset`)
- Drift estimation: stable, linear, insufficient data, short time span
- JSON number extraction edge cases

## What's NOT in This PR

- No UI changes (M2–M4)
- No customizer integration (M5)
- Thresholds are hardcoded constants (will be configurable in M5)

Implements #690 M1.

Kpa-clawbot 84f03f4f41 fix: hide undecryptable channel messages by default (#727) (#728)
## Problem

Channels page shows 53K 'Unknown' messages — undecryptable GRP_TXT
packets with no content. Pure noise.

## Fix

- Backend: channels API filters out undecrypted messages by default
- `?includeEncrypted=true` param to include them
- Frontend: 'Show encrypted' toggle in channels sidebar
- Unknown channels grayed out with '(no key)' label
- Toggle persists in localStorage

Fixes #727

Kpa-clawbot 71be54f085 feat: DB-backed channel messages for full history (#725 M1) (#726)
## Summary

Switches channel API endpoints to query SQLite instead of the in-memory
packet store, giving users access to the full message history.

Implements #725 (M1 only — DB-backed channel messages). Does NOT close
#725 — M2-M5 (custom channels, PSK, persistence, retroactive decryption)
remain.

## Problem

Channel endpoints (`/api/channels`, `/api/channels/{hash}/messages`)
preferred the in-memory packet store when available. The store is
bounded by `packetStore.maxMemoryMB` — typically showing only recent
messages. The SQLite database has the complete history (weeks/months of
channel messages) but was only used as a fallback when the store was nil
(never in production).

## Fix

Reversed the preference order: DB first, in-memory store fallback.
Region filtering added to the DB path.

Kpa-clawbot 7af91f7ef6 fix: perf page shows tracked memory instead of heap allocation (#718)
## Summary

The perf page "Memory Used" tile displayed `estimatedMB` (Go
`runtime.HeapAlloc`), which includes all Go runtime allocations — not
just packet store data. This made the displayed value misleading: it
showed ~2.4GB heap when only ~833MB was actual tracked packet data.

## Changes

### Frontend (`public/perf.js`)
- Primary tile now shows `trackedMB` as **"Tracked Memory"** — the
self-accounted packet store memory
- Added separate **"Heap (debug)"** tile showing `estimatedMB` for
runtime visibility

### Backend
- **`types.go`**: Added `TrackedMB` field to `HealthPacketStoreStats`
struct
- **`routes.go`**: Populate `TrackedMB` in `/health` endpoint response
from `GetPerfStoreStatsTyped()`
- **`routes_test.go`**: Assert `trackedMB` exists in health endpoint's
`packetStore`
- **`testdata/golden/shapes.json`**: Updated shape fixture with new
field

### What was already correct
- `/api/perf/stats` already exposed both `estimatedMB` and `trackedMB`
- `trackedMemoryMB()` method already existed in store.go
- Eviction logic already used `trackedBytes` (not HeapAlloc)

## Testing
- All Go tests pass (`go test ./... -count=1`)
- No frontend logic changes beyond template string field swap

Fixes #717

copelaje 922ebe54e7 BYOP Advert signature validation (#686)
For BYOP mode in the packet analyzer, perform signature validation on
advert packets and display whether successful or not. This is added as
we observed many corrupted advert packets that would be easily
detectable as such if signature validation checks were performed.

At present this MR is just to add this status in BYOP mode so there is
minimal impact to the application and no performance penalty for having
to perform these checks on all packets. Moving forward it probably makes
sense to do these checks on all advert packets so that corrupt packets
can be ignored in several contexts (like node lists for example).

Let me know what you think and I can adjust as needed.

Kpa-clawbot 22bf33700e Fix: filter path-hop candidates by resolved_path to prevent prefix collisions (#658)
## Problem

The "Paths Through This Node" API endpoint (`/api/nodes/{pubkey}/paths`)
returns unrelated packets when two nodes share a hex prefix. For
example, querying paths for "Kpa Roof Solar" (`c0dedad4...`) returns 316
packets that actually belong to "C0ffee SF" (`C0FFEEC7...`) because both
share the `c0` prefix in the `byPathHop` index.

Fixes #655

## Root Cause

`handleNodePaths()` in `routes.go` collects candidates from the
`byPathHop` index using 2-char and 4-char hex prefixes for speed, but
never verifies that the target node actually appears in each candidate's
resolved path. The broad index lookup is intentional, but the
**post-filter was missing**.

## Fix

Added `nodeInResolvedPath()` helper in `store.go` that checks whether a
transmission's `resolved_path` (from the neighbor affinity graph via
`resolveWithContext`) contains the target node's full pubkey. The
filter:

- **Includes** packets where `resolved_path` contains the target node's
full pubkey
- **Excludes** packets where `resolved_path` resolved to a different
node (prefix collision)
- **Excludes** packets where `resolved_path` is nil/empty (ambiguous —
avoids false positives)

The check examines both the best observation's resolved_path
(`tx.ResolvedPath`) and all individual observations, so packets are
included if *any* observation resolved the target.

## Tests

- `TestNodeInResolvedPath` — unit test for the helper with 5 cases
(match, different node, nil, all-nil elements, match in observation
only)
- `TestNodePathsPrefixCollisionFilter` — integration test: two nodes
sharing `aa` prefix, verifies the collision packet is excluded from one
and included for the other
- Updated test DB schema to include `resolved_path` column and seed data
with resolved pubkeys
- All existing tests pass (165 additions, 8 modifications)

## Performance

No impact on hot paths. The filter runs once per API call on the
already-collected candidate set (typically small). `nodeInResolvedPath`
is O(observations × hops) per candidate — negligible since observations
per transmission are typically 1–5.

Kpa-clawbot 0f5e2db5cf feat: auto-generated OpenAPI 3.0 spec endpoint + Swagger UI (#530) (#632)
## Summary

Auto-generated OpenAPI 3.0.3 spec endpoint (`/api/spec`) and Swagger UI
(`/api/docs`) for the CoreScope API.

## What

- **`cmd/server/openapi.go`** — Route metadata map
(`routeDescriptions()`) + spec builder that walks the mux router to
generate a complete OpenAPI 3.0.3 spec at runtime. Includes:
- All 47 API endpoints grouped by tag (admin, analytics, channels,
config, nodes, observers, packets)
- Query parameter documentation for key endpoints (packets, nodes,
search, resolve-hops)
  - Path parameter extraction from mux `{name}` patterns
  - `ApiKeyAuth` security scheme for API-key-protected endpoints
  - Swagger UI served as a self-contained HTML page using unpkg CDN

- **`cmd/server/openapi_test.go`** — Tests for spec endpoint (validates
JSON structure, required fields, path count, security schemes,
self-exclusion of `/api/spec` and `/api/docs`), Swagger UI endpoint, and
`extractPathParams` helper.

- **`cmd/server/routes.go`** — Stores router reference on `Server`
struct for spec generation; registers `/api/spec` and `/api/docs`
routes.

## Design Decisions

- **Runtime spec generation** vs static YAML: The spec walks the actual
router, so it can never drift from registered routes. Route metadata
(summaries, descriptions, tags, auth flags) is maintained in a parallel
map — the test enforces minimum path count to catch drift.
- **No external dependencies**: Uses only stdlib + existing gorilla/mux.
Swagger UI loaded from unpkg CDN (no vendored assets).
- **Security tagging**: Auth-protected endpoints (those behind
`requireAPIKey` middleware) are tagged with `security: [{ApiKeyAuth:
[]}]` in the spec, matching the actual middleware configuration.

## Testing

- `go test -run TestOpenAPI` — validates spec structure, field presence,
path count ≥ 20, security schemes
- `go test -run TestSwagger` — validates HTML response with swagger-ui
references
- `go test -run TestExtractPathParams` — unit tests for path parameter
extraction

Kpa-clawbot dc5b5ce9a0 fix: reject weak/default API keys + startup warning (#532) (#628)
## Summary

Hardens API key security for write endpoints (fixes #532):

1. **Constant-time comparison** — uses
`crypto/subtle.ConstantTimeCompare` to prevent timing attacks on API key
validation
2. **Weak key blocklist** — rejects known default/example keys (`test`,
`password`, `change-me`, `your-secret-api-key-here`, etc.)
3. **Minimum length enforcement** — keys shorter than 16 characters are
rejected
4. **Startup warning** — logs a clear warning if the configured key is
weak or a known default
5. **Generic error messages** — HTTP 403 response uses opaque
"forbidden" message to prevent information leakage about why a key was
rejected

### Security Model
- **Empty key** → all write endpoints disabled (403)
- **Weak/default key** → all write endpoints disabled (403), startup
warning logged
- **Wrong key** → 401 unauthorized
- **Strong correct key** → request proceeds

### Files Changed
- `cmd/server/config.go` — `IsWeakAPIKey()` function + blocklist
- `cmd/server/routes.go` — constant-time comparison via
`constantTimeEqual()`, weak key rejection
- `cmd/server/main.go` — startup warning for weak keys
- `cmd/server/apikey_security_test.go` — comprehensive test coverage
- `cmd/server/routes_test.go` — existing tests updated to use strong
keys

### Reviews
-  Self-review: all security properties verified
-  djb Final Review: timing fix correct, blocklist pragmatic, error
messages opaque, tests comprehensive. **Verdict: Ship it.**

### Test Results
All existing + new tests pass. Coverage includes: weak key detection
(blocklist + length + case-insensitive), empty key handling, strong key
acceptance, wrong key rejection, and constant-time comparison.

Kpa-clawbot 767c8a5a3e perf: async chunked backfill — HTTP serves within 2 minutes (#612) (#614)
## Summary

Adds two config knobs for controlling backfill scope and neighbor graph
data retention, plus removes the dead synchronous backfill function.

## Changes

### Config knobs

#### `resolvedPath.backfillHours` (default: 24)
Controls how far back (in hours) the async backfill scans for
observations with NULL `resolved_path`. Transmissions with `first_seen`
older than this window are skipped, reducing startup time for instances
with large historical datasets.

#### `neighborGraph.maxAgeDays` (default: 30)
Controls the maximum age of `neighbor_edges` entries. Edges with
`last_seen` older than this are pruned from both SQLite and the
in-memory graph. Pruning runs on startup (after a 4-minute stagger) and
every 24 hours thereafter.

### Dead code removal
- Removed the synchronous `backfillResolvedPaths` function that was
replaced by the async version.

### Implementation details
- `backfillResolvedPathsAsync` now accepts a `backfillHours` parameter
and filters by `tx.FirstSeen`
- `NeighborGraph.PruneOlderThan(cutoff)` removes stale edges from the
in-memory graph
- `PruneNeighborEdges(conn, graph, maxAgeDays)` prunes both DB and
in-memory graph
- Periodic pruning ticker follows the same pattern as metrics pruning
(24h interval, staggered start)
- Graceful shutdown stops the edge prune ticker

### Config example
Both knobs added to `config.example.json` with `_comment` fields.

## Tests
- Config default/override tests for both knobs
- `TestGraphPruneOlderThan` — in-memory edge pruning
- `TestPruneNeighborEdgesDB` — SQLite + in-memory pruning together
- `TestBackfillRespectsHourWindow` — verifies old transmissions are
excluded by backfill window
