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 caf3851ff8 feat(server): add opt-in HTTP gzip and WebSocket permessage-deflate compression (#934)
## Summary

- Adds `"compression": {"gzip": true, "websocket": true}` config option
(both `false` by default — no behavior change)
- HTTP gzip middleware wraps the entire router; skips WebSocket upgrade
requests and clients without `Accept-Encoding: gzip`
- WebSocket permessage-deflate enabled via
`hub.upgrader.EnableCompression` when `websocket: true`
- `CompressionConfig` struct and `GZipEnabled()` /
`WSCompressionEnabled()` helpers on `Config`
- `Hub.upgrader` moved from package-level var to struct field so tests
using `NewHub()` don't need changes

## Why opt-in / off by default

Operators behind a reverse proxy that already compresses (nginx, Caddy
with `encode gzip`) should leave this off to avoid double-compression.
Only enable when the proxy does **not** compress.

## Test plan

- [x] `TestCompressionConfigDefaults` — both helpers return false when
`Compression` is nil
- [x] `TestCompressionConfigExplicitFalse` — both helpers return false
when set to false
- [x] `TestCompressionConfigEnabled` — both helpers return true when set
to true
- [x] `TestGZipMiddlewareCompresses` — response body is valid gzip,
headers set correctly
- [x] `TestGZipMiddlewareSkipsNoAcceptEncoding` — passthrough when
client doesn't send Accept-Encoding: gzip
- [x] `TestGZipMiddlewareSkipsWebSocket` — WebSocket upgrades are never
gzip-wrapped

All 6 tests pass (`go test ./...` in `cmd/server`).

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 9383201c07 refactor(db): finish #1283 — Option 4: ingestor owns neighbor-graph + schema migrations; server is read-only (fixes #1287) (#1289)
Red commit:
https://github.com/Kpa-clawbot/CoreScope/commit/eae179b99b5fd34924547632aa8f8025c405aa53
(CI: pending — opens with this PR)

Finishes #1283. RED test `TestServerSourceHasNoCachedRWCalls` goes from
failing (13 writer call-sites) to GREEN (zero). Per #1287 Option 4
(https://github.com/Kpa-clawbot/CoreScope/issues/1287#issuecomment-4485099992):
ingestor owns the neighbor graph build + persist; server reads the
snapshot.

**Category A — Schema migrations** → new `internal/dbschema` package.
`dbschema.Apply(rw)` runs in `cmd/ingestor` startup (in `OpenStore`).
`dbschema.AssertReady(ro)` runs in `cmd/server/main.go` and
FATAL-LOG-EXITS if any expected column/index/table is missing — the
operator must restart the ingestor first. Covers indexes,
`neighbor_edges`, `observations.resolved_path`,
`observers.{inactive,last_packet_at,iata}`,
`(inactive_)nodes.foreign_advert`, `transmissions.from_pubkey`.

**Category B — Backfill** → ingestor.
`BackfillFromPubkey` and observer-blacklist soft-delete moved to
`cmd/ingestor/maintenance.go`. Server keeps an inert
`fromPubkeyBackfillSnapshot` stub for `/api/healthz` API compatibility.

**Category C — Neighbor-graph persistence (Option 4)** → ingestor
writes, server reads.
- Ingestor (`cmd/ingestor/neighbor_builder.go`): every 60s scans
`observations + transmissions`, extracts edges (originator↔first-hop for
ADVERTs; observer↔last-hop for all), resolves hop prefixes via a
node-table prefix index, upserts into `neighbor_edges`.
- Server (`cmd/server/neighbor_recomputer.go`): every 60s re-reads
`neighbor_edges` and atomic-swaps the resulting `NeighborGraph` into
`s.graph`. Initial load is synchronous on startup. All server-side
incremental edge writers (the two `asyncPersistResolvedPathsAndEdges`
paths in `cmd/server/store.go`) are gone.
- Neighbor-edge daily prune (`PruneNeighborEdges`) moved to ingestor.

**Why Option 4**: clean read/write separation, no startup CPU spike
(server loads existing snapshot instead of rebuilding from history), no
IPC/delta-protocol churn. Staleness budget ~60s — same model as the
analytics recomputers in #1240 / #1248 / #672 axis 2.

**Recomputer interval default for neighbor graph**: 60s
(`NeighborGraphRecomputerDefaultInterval`,
`NeighborEdgesBuilderInterval`).

**Invariants added**:
- `TestServerSourceHasNoCachedRWCalls` (RED commit eae179b9): grep
enforces zero `cachedRW(`, `mode=rw`, or `sql.Open(_journal_mode=WAL…)`
in non-test `cmd/server/` sources.
- `TestServerStartupRequiresMigratedSchema`: server refuses to start
against an unmigrated DB.
- `TestNeighborGraphRecomputerLoadsSnapshot`: post-write snapshot is
picked up on the next refresh.
- `TestNeighborEdgesBuilderUpsertsFromObservations`: end-to-end pipeline
writes the expected edge.

`grep cachedRW cmd/server/*.go | grep -v _test.go` → 0 matches.

Fixes #1287.

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 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 ae17a2be12 perf(#1262): /api/nodes?limit=2000 cold-miss 15.7s → <100ms — prewarm repeater enrichment cache (#1263)
RED commit: `22ce5736066142583017cad7303fa48d9e00ccf0` — CI on red:
https://github.com/Kpa-clawbot/CoreScope/actions?query=branch%3Afix%2Fissue-1262

## Problem
After #1260 added a 15s-TTL bulk cache for repeater enrichment in
`handleNodes`,
`/api/nodes` (default limit) dropped to ~500ms. But
`/api/nodes?limit=2000` —
called by `public/live.js` at SPA startup for hop resolution — still
took
**15.7s cold** on staging (75k tx, 600 nodes). Warm hits were ~40ms.

Root cause: the bulk cache was lazily populated on the first request
after
TTL expiry. The rebuild ran on the request-serving goroutine. Every cold
SPA
load triggered the rebuild and ate 15s.

## Fix
Add `StartRepeaterEnrichmentRecomputer` — a steady-state background
recomputer that mirrors the `analytics_recomputer.go` pattern from
#1240:

- **Prewarm**: initial synchronous compute on Start so the first request
  hits a populated cache.
- **Steady-state**: ticker refreshes the snapshot every 5min
(configurable
  via the existing analytics recompute interval knob).
- **Panic-safe** + idempotent Start.

Wired into `main.go` right after `StartAnalyticsRecomputers`, using
`cfg.GetHealthThresholds().RelayActiveHours` as the window.

## Test
`TestHandleNodesLimit2000ColdMiss` — seeds 600 nodes + 150k non-advert
tx with repeaters indexed under a shared 1-byte hop prefix (matches
production hop-prefix collisions), starts the recomputer, then issues
`/api/nodes?limit=2000` with **no HTTP warmup**.

| State | Latency |
|---|---|
| Before (master, on-thread rebuild) | 3.37s |
| After (prewarm + steady-state) | 56ms |
| Budget | 2s |

Staging end-to-end: 15.7s → expected sub-100ms on the same call path.

Red commit (`22ce5736066142583017cad7303fa48d9e00ccf0`) compiles with a
no-op stub of the new method so the
test fails on the latency **assertion**, not a missing symbol.

Fixes #1262

Kpa-clawbot 356f001027 perf(#1240): steady-state background recompute for analytics endpoints (#1248)
RED commit: `27630f6a` — adds latency test that fails on master
(p99=225ms > 50ms budget) and a stub `StartAnalyticsRecomputers` that
returns a no-op so the assertion (not a build error) gates the change.

GREEN commit: `20fbbceb` — wires real background recompute
infrastructure. Test passes at p99=~1µs.

## What changed

Replaces the on-request "compute-then-cache" pattern for the
default-shape analytics queries with a steady-state background recompute
loop. Reads always hit an `atomic.Value` snapshot in <1µs regardless of
compute cost or writer contention. Operator principle: serving slightly
stale data quickly beats real-time data slowly.

## Endpoints converted (default 5min interval each)

| Endpoint | Cold compute | Recomputer interval |
|---|---|---|
| `/api/analytics/topology` | ~5s | 5 min |
| `/api/analytics/rf` | ~4s | 5 min |
| `/api/analytics/distance` | ~3s | 5 min |
| `/api/analytics/channels` | ~0.5s | 5 min |
| `/api/analytics/hash-collisions` | ~0.5s | 5 min |
| `/api/analytics/hash-sizes` | ~22ms | 5 min |

All intervals configurable per-endpoint via
`analytics.recomputeIntervalSeconds.<name>` in `config.json`; documented
in `config.example.json`. Default override via
`analytics.defaultIntervalSeconds`.

## Scope: default query only

Only the canonical shape `(region="", window=zero)` is precomputed.
Region- or window-filtered requests fall back to the legacy TTL cache +
on-request compute — keeps recomputer count bounded (6, not 6×N×M).

## Latency

Test `TestAnalyticsRecomputerSteadyStateLatency`: 100 concurrent readers
+ 4 writers churning `s.mu.Lock` on 20k distHops.
- Before: p50=188ms p99=225ms (assertion failed)
- After:  p50=240ns p99=1.1µs (atomic load + map return)

## Shutdown integration

`StartAnalyticsRecomputers` returns a stop closure invoked from
`main.go`'s SIGTERM handler BEFORE `dbClose()` so any in-flight SQLite
compute drains cleanly. `TestAnalyticsRecomputerShutdownNoLeak` confirms
all 6 goroutines are reaped (Δ=6 within 2s).

## Safety details

- Initial compute is synchronous in `Start()` — first read after startup
never sees nil.
- `recover()` inside `runOnce` keeps a compute panic from killing the
goroutine; previous snapshot remains valid.
- `analyticsRecomputerMu` is a sync.RWMutex; recomputer pointers are
read-locked in the hot path. The atomic.Value swap inside `runOnce` is
lock-free.

Fixes #1240.

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.

efiten 11d2026bb1 feat(startup): hot startup — load hotStartupHours synchronously, fill retentionHours in background (#1187)
Closes #1183

## Summary

- Adds `packetStore.hotStartupHours` config key (float64, default 0 =
disabled). When set, `Load()` loads only that many hours of data
synchronously, reducing startup time on large DBs. Background goroutine
fills the remaining `retentionHours` window in daily chunks after
startup completes.
- A background goroutine (`loadBackgroundChunks`) fills the remaining
`retentionHours` window in daily chunks after startup completes.
Analytics indexes are rebuilt once at the end.
- `QueryPackets` and `QueryGroupedPackets` check `oldestLoaded` and fall
back to `db.QueryPackets()` for any query whose `Since`/`Until` predates
the in-memory window — covering days 8–30 permanently (beyond
`retentionHours`) and the background-fill gap during startup.
- `/api/perf` gains `hotStartupHours`, `backgroundLoadComplete`, and
`backgroundLoadProgress` fields inside `packetStore` so operators can
monitor the fill.

### Drive-by fixes

- E2E: added `gotoPackets` navigation helper used across packet-related
tests
- E2E: rewrote stripe assertion to check per-row stripe parity rather
than a fragile computed-style comparison
- E2E: theme test updated to use `#/home` as the initial route (was
`#/`)
- `db.go`: removed the RFC3339→unix-timestamp subquery path in
`buildTransmissionWhere`; `t.first_seen` is now always compared directly
as a string for both RFC3339 and non-RFC3339 inputs

## Configuration

```json
"packetStore": {
  "retentionHours": 168,
  "hotStartupHours": 24
}
```

`hotStartupHours: 0` (default) preserves existing behavior exactly.
Recommended for large DBs to reduce startup time; set to 0 to disable
(loads full retentionHours at startup, legacy behavior).

## Test plan

- [x] `TestHotStartupConfig_Clamp` — clamping when `hotStartupHours >
retentionHours`
- [x] `TestHotStartupConfig_ZeroIsDisabled` — zero leaves feature
disabled
- [x] `TestHotStartup_LoadsOnlyHotWindow` — only hot-window packets in
memory after `Load()`
- [x] `TestHotStartup_DisabledWhenZero` — all retention packets loaded
when disabled
- [x] `TestHotStartup_loadChunk_AddsOlderData` — chunk merges correctly,
ASC order maintained
- [x] `TestHotStartup_BackgroundFillsToRetention` — background goroutine
fills to `retentionHours`
- [x] `TestHotStartup_ChunkErrorRecovery` — chunk SQL failure logged and
skipped, loop terminates
- [x] `TestHotStartup_SQLFallback_TriggeredForOldDate` — query before
`oldestLoaded` routes to SQL
- [x] `TestHotStartup_SQLFallback_NotTriggeredForRecentDate` — recent
query stays in-memory
- [x] `TestHotStartup_PerfStats` — new fields present in
`GetPerfStoreStats()` (backs the perf endpoint)
- [x] `TestHotStartup_PerfStoreHTTP` — HTTP-level: GET /api/perf returns
`hotStartupHours`, `backgroundLoadComplete`, `backgroundLoadProgress` in
`packetStore`

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 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 d05e468598 feat(memlimit): GOMEMLIMIT support, derive from packetStore.maxMemoryMB (#836) (#1077)
## Summary

Implements **part 1** of #836 — `GOMEMLIMIT` support so the Go runtime
self-throttles GC under cgroup memory pressure instead of getting
SIGKILLed.

(Parts 2 & 3 — bounded cold-load batching + README ops docs — land in
follow-up PRs.)

## Behavior

On startup `cmd/server/main.go` now calls `applyMemoryLimit(maxMemoryMB,
envSet)`:

| Condition | Action | Log |
|---|---|---|
| `GOMEMLIMIT` env set | Honor the runtime's parse, do nothing |
`[memlimit] using GOMEMLIMIT from environment (...)` |
| env unset, `packetStore.maxMemoryMB > 0` | `debug.SetMemoryLimit(maxMB
* 1.5 MiB)` | `[memlimit] derived from packetStore.maxMemoryMB=512 → 768
MiB (1.5x headroom)` |
| env unset, `maxMemoryMB == 0` | No-op | `[memlimit] no soft memory
limit set ... recommend setting one to avoid container OOM-kill` |

The 1.5x headroom covers Go's NextGC trigger at ~2× live heap (per #836
heap profile: 680 MB live → 1.38 GB NextGC).

## Tests (TDD red→green visible in commit history)

- `TestApplyMemoryLimit_FromEnv` — env wins, function does not override
- `TestApplyMemoryLimit_DerivedFromMaxMemoryMB` — verifies bytes
computation + `debug.SetMemoryLimit` actually applied at runtime
- `TestApplyMemoryLimit_None` — no env, no config → reports `"none"`, no
side effect

Red commit: `7de3c62` (assertion failures, builds clean)
Green commit: `454516d`

## Config docs

`config.example.json` `packetStore._comment_gomemlimit` documents
env/derived/override behavior.

## Out of scope

- Cold-load transient bounding (item 2 in #836)
- README container-size table (item 3)
- QA §1.1 rewrite

Closes part 1 of #836.

Kpa-clawbot dd2f044f2b fix: cache RW SQLite connection + dedup DBConfig (closes #921) (#982)
Closes #921

## Summary

Follow-up to #920 (incremental auto-vacuum). Addresses both items from
the adversarial review:

### 1. RW connection caching

Previously, every call to `openRW(dbPath)` opened a new SQLite RW
connection and closed it after use. This happened in:
- `runIncrementalVacuum` (~4x/hour)
- `PruneOldPackets`, `PruneOldMetrics`, `RemoveStaleObservers`
- `buildAndPersistEdges`, `PruneNeighborEdges`
- All neighbor persist operations

Now a single `*sql.DB` handle (with `MaxOpenConns(1)`) is cached
process-wide via `cachedRW(dbPath)`. The underlying connection pool
manages serialization. The original `openRW()` function is retained for
one-shot test usage.

### 2. DBConfig dedup

`DBConfig` was defined identically in both `cmd/server/config.go` and
`cmd/ingestor/config.go`. Extracted to `internal/dbconfig/` as a shared
package; both binaries now use a type alias (`type DBConfig =
dbconfig.DBConfig`).

## Tests added

| Test | File |
|------|------|
| `TestCachedRW_ReturnsSameHandle` | `cmd/server/rw_cache_test.go` |
| `TestCachedRW_100Calls_SingleConnection` |
`cmd/server/rw_cache_test.go` |
| `TestGetIncrementalVacuumPages_Default` |
`internal/dbconfig/dbconfig_test.go` |
| `TestGetIncrementalVacuumPages_Configured` |
`internal/dbconfig/dbconfig_test.go` |

## Verification

```
ok  github.com/corescope/server    20.069s
ok  github.com/corescope/ingestor  47.117s
ok  github.com/meshcore-analyzer/dbconfig  0.003s
```

Both binaries build cleanly. 100 sequential `cachedRW()` calls return
the same handle with exactly 1 entry in the cache map.

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.

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 e1a1be1735 fix(server): add observers.inactive column at startup if missing (root cause of CI flake) (#961)
## The actual root cause

PR #954 added `WHERE inactive IS NULL OR inactive = 0` to the server's
observer queries, but the `inactive` column is only added by the
**ingestor** migration (`cmd/ingestor/db.go:344-354`). When the server
runs against a DB the ingestor never touched (e.g. the e2e fixture), the
column doesn't exist:

```
$ sqlite3 test-fixtures/e2e-fixture.db "SELECT COUNT(*) FROM observers WHERE inactive IS NULL OR inactive = 0;"
Error: no such column: inactive
```

The server's `db.QueryRow().Scan()` swallows that error →
`totalObservers` stays 0 → `/api/observers` returns empty → map test
fails with "No map markers/overlays found".

This explains all the failing CI runs since #954 merged. PR #957
(freshen fixture) helped with the `nodes` time-rot but couldn't fix the
missing-column problem. PR #960 (freshen observers) added the right
timestamps but the column was still missing. PR #959 (data-loaded in
finally) fixed a different real bug. None of those touched the actual
mechanism.

## Fix

Mirror the existing `ensureResolvedPathColumn` pattern: add
`ensureObserverInactiveColumn` that runs at server startup, checks if
the column exists via `PRAGMA table_info`, adds it with `ALTER TABLE
observers ADD COLUMN inactive INTEGER DEFAULT 0` if missing.

Wired into `cmd/server/main.go` immediately after
`ensureResolvedPathColumn`.

## Verification

End-to-end on a freshened fixture:

```
$ sqlite3 /tmp/e2e-verify.db "PRAGMA table_info(observers);" | grep inactive
(no output — column absent)

$ ./cs-fixed -port 13702 -db /tmp/e2e-verify.db -public public &
[store] Added inactive column to observers

$ curl 'http://localhost:13702/api/observers'
returned=31    # was 0 before fix
```

`go test ./...` passes (19.8s).

## Lessons

I should have run `sqlite3 fixture "SELECT ... WHERE inactive ..."`
directly the first time the map test failed after #954 instead of
writing four "fix" PRs that didn't address the actual mechanism.
Apologies for the wild goose chase.

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

Kpa-clawbot aeae7813bc fix: enable SQLite incremental auto-vacuum so DB shrinks after retention (#919) (#920)
Closes #919

## Summary

Enables SQLite incremental auto-vacuum so the database file actually
shrinks after retention reaper deletes old data. Previously, `DELETE`
operations freed pages internally but never returned disk space to the
OS.

## Changes

### 1. Auto-vacuum on new databases
- `PRAGMA auto_vacuum = INCREMENTAL` set via DSN pragma before
`journal_mode(WAL)` in the ingestor's `OpenStoreWithInterval`
- Must be set before any tables are created; DSN ordering ensures this

### 2. Post-reaper incremental vacuum
- `PRAGMA incremental_vacuum(N)` runs after every retention reaper cycle
(packets, metrics, observers, neighbor edges)
- N defaults to 1024 pages, configurable via `db.incrementalVacuumPages`
- Noop on `auto_vacuum=NONE` databases (safe before migration)
- Added to both server and ingestor

### 3. Opt-in full VACUUM for existing databases
- Startup check logs a clear warning if `auto_vacuum != INCREMENTAL`
- `db.vacuumOnStartup: true` config triggers one-time `PRAGMA
auto_vacuum = INCREMENTAL; VACUUM`
- Logs start/end time for operator visibility

### 4. Documentation
- `docs/user-guide/configuration.md`: retention section notes that
lowering retention doesn't immediately shrink the DB
- `docs/user-guide/database.md`: new guide covering WAL, auto-vacuum,
migration, manual VACUUM

### 5. Tests
- `TestNewDBHasIncrementalAutoVacuum` — fresh DB gets `auto_vacuum=2`
- `TestExistingDBHasAutoVacuumNone` — old DB stays at `auto_vacuum=0`
- `TestVacuumOnStartupMigratesDB` — full VACUUM sets `auto_vacuum=2`
- `TestIncrementalVacuumReducesFreelist` — DELETE + vacuum shrinks
freelist
- `TestCheckAutoVacuumLogs` — handles both modes without panic
- `TestConfigIncrementalVacuumPages` — config defaults and overrides

## Migration path for existing databases

1. On startup, CoreScope logs: `[db] auto_vacuum=NONE — DB needs
one-time VACUUM...`
2. Set `db.vacuumOnStartup: true` in config.json
3. Restart — VACUUM runs (blocks startup, minutes on large DBs)
4. Remove `vacuumOnStartup` after migration

## Test results

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.

Fixes #786

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
- [x] `TestObserverDaysOrDefault` (server) —
nil/zero/positive/keep-forever
- [x] Both binaries compile cleanly (`go build`)
- [ ] Manual: verify observer count decreases after retention period on
a live instance

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 05fbcb09dd fix: wire cacheTTL.analyticsHashSizes config to collision cache (#420) (#622)
## Summary

Fixes #420 — wires `cacheTTL` config values to server-side cache
durations that were previously hardcoded.

## Problem

`collisionCacheTTL` was hardcoded at 60s in `store.go`. The config has
`cacheTTL.analyticsHashSizes: 3600` (1 hour) but it was never read — the
`/api/config/cache` endpoint just passed the raw map to the client
without applying values server-side.

## Changes

- **`store.go`**: Add `cacheTTLSec()` helper to safely extract duration
values from the `cacheTTL` config map. `NewPacketStore` now accepts an
optional `cacheTTL` map (variadic, backward-compatible) and wires:
  - `cacheTTL.analyticsHashSizes` → `collisionCacheTTL`
  - `cacheTTL.analyticsRF` → `rfCacheTTL`
- **Default changed**: `collisionCacheTTL` default raised from 60s →
3600s (1 hour). Hash collision computation is expensive and data changes
rarely — 60s was causing unnecessary recomputation.
- **`main.go`**: Pass `cfg.CacheTTL` to `NewPacketStore`.
- **Tests**: Added `TestCacheTTLFromConfig` and `TestCacheTTLDefaults`
in eviction_test.go. Updated existing `TestHashCollisionsCacheTTL` for
the new default.

## Audit of other cacheTTL values

The remaining `cacheTTL` keys (`stats`, `nodeDetail`, `nodeHealth`,
`nodeList`, `bulkHealth`, `networkStatus`, `observers`, `channels`,
`channelMessages`, `analyticsTopology`, `analyticsChannels`,
`analyticsSubpaths`, `analyticsSubpathDetail`, `nodeAnalytics`,
`nodeSearch`, `invalidationDebounce`) are **client-side only** — served
via `/api/config/cache` and consumed by the frontend. They don't have
corresponding server-side caches to wire to. The only server-side caches
(`rfCache`, `topoCache`, `hashCache`, `chanCache`, `distCache`,
`subpathCache`, `collisionCache`) all use either `rfCacheTTL` or
`collisionCacheTTL`, both now configurable.

## Complexity

O(1) config lookup at store init time. No hot-path impact.

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

Kpa-clawbot 6f35d4d417 feat: RF Health Dashboard M1 — observer metrics + small multiples grid (#604)
## RF Health Dashboard — M1: Observer Metrics Storage, API & Small
Multiples Grid

Implements M1 of #600.

### What this does

Adds a complete RF health monitoring pipeline: MQTT stats ingestion →
SQLite storage → REST API → interactive dashboard with small multiples
grid.

### Backend Changes

**Ingestor (`cmd/ingestor/`)**
- New `observer_metrics` table via migration system (`_migrations`
pattern)
- Parse `tx_air_secs`, `rx_air_secs`, `recv_errors` from MQTT status
messages (same pattern as existing `noise_floor` and `battery_mv`)
- `INSERT OR REPLACE` with timestamps rounded to nearest 5-min interval
boundary (using ingestor wall clock, not observer timestamps)
- Missing fields stored as NULLs — partial data is always better than no
data
- Configurable retention pruning: `retention.metricsDays` (default 30),
runs on startup + every 24h

**Server (`cmd/server/`)**
- `GET /api/observers/{id}/metrics?since=...&until=...` — per-observer
time-series data
- `GET /api/observers/metrics/summary?window=24h` — fleet summary with
current NF, avg/max NF, sample count
- `parseWindowDuration()` supports `1h`, `24h`, `3d`, `7d`, `30d` etc.
- Server-side metrics retention pruning (same config, staggered 2min
after packet prune)

### Frontend Changes

**RF Health tab (`public/analytics.js`, `public/style.css`)**
- Small multiples grid showing all observers simultaneously — anomalies
pop out visually
- Per-observer cell: name, current NF value, battery voltage, sparkline,
avg/max stats
- NF status coloring: warning (amber) at ≥-100 dBm, critical (red) at
≥-85 dBm — text color only, no background fills
- Click any cell → expanded detail view with full noise floor line chart
- Reference lines with direct text labels (`-100 warning`, `-85
critical`) — not color bands
- Min/max points labeled directly on the chart
- Time range selector: preset buttons (1h/3h/6h/12h/24h/3d/7d/30d) +
custom from/to datetime picker
- Deep linking: `#/analytics?tab=rf-health&observer=...&range=...`
- All charts use SVG, matching existing analytics.js patterns
- Responsive: 3-4 columns on desktop, 1 on mobile

### Design Decisions (from spec)
- Labels directly on data, not in legends
- Reference lines with text labels, not color bands
- Small multiples grid, not card+accordion (Tufte: instant visual fleet
comparison)
- Ingestor wall clock for all timestamps (observer clocks may drift)

### Tests Added

**Ingestor tests:**
- `TestRoundToInterval` — 5 cases for rounding to 5-min boundaries
- `TestInsertMetrics` — basic insertion with all fields
- `TestInsertMetricsIdempotent` — INSERT OR REPLACE deduplication
- `TestInsertMetricsNullFields` — partial data with NULLs
- `TestPruneOldMetrics` — retention pruning
- `TestExtractObserverMetaNewFields` — parsing tx_air_secs, rx_air_secs,
recv_errors

**Server tests:**
- `TestGetObserverMetrics` — time-series query with since/until filters,
NULL handling
- `TestGetMetricsSummary` — fleet summary aggregation
- `TestObserverMetricsAPIEndpoints` — DB query verification
- `TestMetricsAPIEndpoints` — HTTP endpoint response shape
- `TestParseWindowDuration` — duration parsing for h/d formats

### Test Results
```
cd cmd/ingestor && go test ./... → PASS (26s)
cd cmd/server && go test ./... → PASS (5s)
```

### What's NOT in this PR (deferred to M2+)
- Server-side delta computation for cumulative counters
- Airtime charts (TX/RX percentage lines)
- Channel quality chart (recv_error_rate)
- Battery voltage chart
- Reboot detection and chart annotations
- Resolution downsampling (1h, 1d aggregates)
- Pattern detection / automated diagnosis

Kpa-clawbot b0862f7a41 fix: replace time.Tick with NewTicker in prune goroutine for graceful shutdown (#593)
## Summary

Replace `time.Tick()` with `time.NewTicker()` in the auto-prune
goroutine so it stops cleanly during graceful shutdown.

## Problem

`time.Tick` creates a ticker that can never be garbage collected or
stopped. While the prune goroutine runs for the process lifetime, it
won't stop during graceful shutdown — the goroutine leaks past the
shutdown sequence.

## Fix

- Create a `time.NewTicker` and a done channel
- Use `select` to listen on both the ticker and done channel
- Stop the ticker and close the done channel in the shutdown path (after
`poller.Stop()`)
- Pattern matches the existing `StartEvictionTicker()` approach

## Testing

- `go build ./...` — compiles cleanly
- `go test ./...` — all tests pass

you 0c340e1eb6 fix: set hasResolvedPath flag after ensuring column exists
detectSchema() runs at DB open time before ensureResolvedPathColumn()
adds the column during Load(). On first run (or any run where the column
was just added), hasResolvedPath stayed false, causing Load() to skip
reading resolved_path from SQLite. This forced a full backfill of all
observations on every restart, burning CPU for minutes on large DBs.

Fix: set hasResolvedPath = true after ensureResolvedPathColumn succeeds.

Kpa-clawbot ae38cdefb4 feat: server-side hop resolution at ingest — resolved_path (#556)
## Summary

Implements server-side hop prefix resolution at ingest time with a
persisted neighbor graph. Hop prefixes in `path_json` are now resolved
to full 64-char pubkeys at ingest and stored as `resolved_path` on each
observation, eliminating the need for client-side resolution via
`HopResolver`.

Fixes #555

## What changed

### New file: `cmd/server/neighbor_persist.go`
SQLite persistence layer for the neighbor graph and resolved paths:
- `neighbor_edges` table creation and management
- Load/build/persist neighbor edges from/to SQLite
- `resolved_path` column migration on observations
- `resolvePathForObs()` — resolves hop prefixes using
`resolveWithContext` with 4-tier priority (affinity → geo → GPS → first
match)
- Cold startup backfill for observations missing `resolved_path`
- Async persistence of edges and resolved paths during ingest
(non-blocking)

### Modified: `cmd/server/store.go`
- `StoreObs` gains `ResolvedPath []*string` field
- `StoreTx` gains `ResolvedPath []*string` (cached from best
observation)
- `Load()` dynamically includes `resolved_path` in SQL query when column
exists
- `IngestNewFromDB()` resolves paths at ingest time and persists
asynchronously
- `pickBestObservation()` propagates `ResolvedPath` to transmission
- `txToMap()` and `enrichObs()` include `resolved_path` in API responses
- All 7 `pm.resolve()` call sites migrated to `pm.resolveWithContext()`
with the persisted graph
- Broadcast maps include `resolved_path` per observation

### Modified: `cmd/server/db.go`
- `DB` struct gains `hasResolvedPath bool` flag
- `detectSchema()` checks for `resolved_path` column existence
- Graceful degradation when column is absent (test DBs, old schemas)

### Modified: `cmd/server/main.go`
- Startup sequence: ensure tables → load/build graph → backfill resolved
paths → re-pick best observations

### Modified: `cmd/server/routes.go`
- `mapSliceToTransmissions()` and `mapSliceToObservations()` propagate
`resolved_path`
- Node paths handler uses `resolveWithContext` with graph

### Modified: `cmd/server/types.go`
- `TransmissionResp` and `ObservationResp` gain `ResolvedPath []*string`
with `omitempty`

### New file: `cmd/server/neighbor_persist_test.go`
16 tests covering:
- Path resolution (unambiguous, empty, unresolvable prefixes)
- Marshal/unmarshal of resolved_path JSON
- SQLite table creation and column migration (idempotent)
- Edge persistence and loading
- Schema detection
- Full Load() with resolved_path
- API response serialization (present when set, omitted when nil)

## Design decisions

1. **Async persistence** — resolved paths and neighbor edges are written
to SQLite in a goroutine to avoid blocking the ingest loop. The
in-memory state is authoritative.

2. **Schema compatibility** — `DB.hasResolvedPath` flag allows the
server to work with databases that don't yet have the `resolved_path`
column. SQL queries dynamically include/exclude the column.

3. **`pm.resolve()` retained** — Not removed as dead code because
existing tests use it directly. All production call sites now use
`resolveWithContext` with the persisted graph.

4. **Edge persistence is conservative** — Only unambiguous edges (single
candidate) are persisted to `neighbor_edges`. Ambiguous prefixes are
handled by the in-memory `NeighborGraph` via Jaccard disambiguation.

5. **`null` = unresolved** — Ambiguous prefixes store `null` in the
resolved_path array. Frontend falls back to prefix display.

## Performance

- `resolveWithContext` per hop: ~1-5μs (map lookups, no DB queries)
- Typical packet has 0-5 hops → <25μs total resolution overhead per
packet
- Edge/path persistence is async → zero impact on ingest latency
- Backfill is one-time on first startup with the new column

## Test results

```
cd cmd/server && go test ./... -count=1  → ok (4.4s)
cd cmd/ingestor && go test ./... -count=1 → ok (25.5s)
```

Kpa-clawbot bf2e721dd7 feat: auto-inject cache busters at server startup — eliminates merge conflicts (#481)
## Problem

Every PR that touches `public/` files requires manually bumping cache
buster timestamps in `index.html` (e.g. `?v=1775111407`). Since all PRs
change the same lines in the same file, this causes **constant merge
conflicts** — it's been the #1 source of unnecessary PR friction.

## Solution

Replace all hardcoded `?v=TIMESTAMP` values in `index.html` with a
`?v=__BUST__` placeholder. The Go server replaces `__BUST__` with the
current Unix timestamp **once at startup** when it reads `index.html`,
then serves the pre-processed HTML from memory.

Every server restart automatically picks up fresh cache busters — no
manual intervention needed.

## What changed

| File | Change |
|------|--------|
| `public/index.html` | All `v=1775111407` → `v=__BUST__` (28
occurrences) |
| `cmd/server/main.go` | `spaHandler` reads index.html at init, replaces
`__BUST__` with Unix timestamp, serves from memory for `/`,
`/index.html`, and SPA fallback |
| `cmd/server/helpers_test.go` | New `TestSpaHandlerCacheBust` —
verifies placeholder replacement works for root, SPA fallback, and
direct `/index.html` requests. Also added tests for root `/` and
`/index.html` routes |
| `AGENTS.md` | Rule 3 updated: cache busters are now automatic, agents
should not manually edit them |

## Testing

- `go build ./...` — compiles cleanly
- `go test ./...` — all tests pass (including new cache-bust tests)
- `node test-frontend-helpers.js && node test-packet-filter.js && node
test-aging.js` — all frontend tests pass
- No hardcoded timestamps remain in `index.html`

Kpa-clawbot f87eb3601c fix: graceful container shutdown for reliable deployments (#453)
## Summary

Fixes #450 — staging deployment flaky due to container not shutting down
cleanly.

## Root Causes

1. **Server never closed DB on shutdown** — SQLite WAL lock held
indefinitely, blocking new container startup
2. **`httpServer.Close()` instead of `Shutdown()`** — abruptly kills
connections instead of draining them
3. **No `stop_grace_period` in compose configs** — Docker sends SIGTERM
then immediately SIGKILL (default 10s is often not enough for WAL
checkpoint)
4. **Supervisor didn't forward SIGTERM** — missing
`stopsignal`/`stopwaitsecs` meant Go processes got SIGKILL instead of
graceful shutdown
5. **Deploy scripts used default `docker stop` timeout** — only 10s
grace period

## Changes

### Go Server (`cmd/server/`)
- **Graceful HTTP shutdown**: `httpServer.Shutdown(ctx)` with 15s
context timeout — drains in-flight requests before closing
- **WebSocket cleanup**: New `Hub.Close()` method sends `CloseGoingAway`
frames to all connected clients
- **DB close on shutdown**: Explicitly closes DB after HTTP server stops
(was never closed before)
- **WAL checkpoint**: `PRAGMA wal_checkpoint(TRUNCATE)` before DB close
— flushes WAL to main DB file and removes WAL/SHM lock files

### Go Ingestor (`cmd/ingestor/`)
- **WAL checkpoint on shutdown**: New `Store.Checkpoint()` method,
called before `Close()`
- **Longer MQTT disconnect timeout**: 5s (was 1s) to allow in-flight
messages to drain

### Docker Compose (all 4 variants)
- Added `stop_grace_period: 30s` and `stop_signal: SIGTERM`

### Supervisor Configs (both variants)
- Added `stopsignal=TERM` and `stopwaitsecs=20` to server and ingestor
programs

### Deploy Scripts
- `deploy-staging.sh`: `docker stop -t 30` with explicit grace period
- `deploy-live.sh`: `docker stop -t 30` with explicit grace period

## Shutdown Sequence (after fix)

1. Docker sends SIGTERM to supervisord (PID 1)
2. Supervisord forwards SIGTERM to server + ingestor (waits up to 20s
each)
3. Server: stops poller → drains HTTP (15s) → closes WS clients →
checkpoints WAL → closes DB
4. Ingestor: stops tickers → disconnects MQTT (5s) → checkpoints WAL →
closes DB
5. Docker waits up to 30s total before SIGKILL

## Tests

All existing tests pass:
- `cd cmd/server && go test ./...` 
- `cd cmd/ingestor && go test ./...`

efiten fe314be3a8 feat: geo_filter enforcement, DB pruning, geofilter-builder tool, HB column (#215)
## Summary

Several features and fixes from a live deployment of the Go v3.0.0
backend.

### geo_filter — full enforcement

- **Go backend config** (`cmd/server/config.go`,
`cmd/ingestor/config.go`): added `GeoFilterConfig` struct so
`geo_filter.polygon` and `bufferKm` from `config.json` are parsed by
both the server and ingestor
- **Ingestor** (`cmd/ingestor/geo_filter.go`, `cmd/ingestor/main.go`):
ADVERT packets from nodes outside the configured polygon + buffer are
dropped *before* any DB write — no transmission, node, or observation
data is stored
- **Server API** (`cmd/server/geo_filter.go`, `cmd/server/routes.go`):
`GET /api/config/geo-filter` endpoint returns the polygon + bufferKm to
the frontend; `/api/nodes` responses filter out any out-of-area nodes
already in the DB
- **Frontend** (`public/map.js`, `public/live.js`): blue polygon overlay
(solid inner + dashed buffer zone) on Map and Live pages, toggled via
"Mesh live area" checkbox, state shared via localStorage

### Automatic DB pruning

- Add `retention.packetDays` to `config.json` to delete transmissions +
observations older than N days on a daily schedule (1 min after startup,
then every 24h). Nodes and observers are never pruned.
- `POST /api/admin/prune?days=N` for manual runs (requires `X-API-Key`
header if `apiKey` is set)

```json
"retention": {
  "nodeDays": 7,
  "packetDays": 30
}
```

### tools/geofilter-builder.html

Standalone HTML tool (no server needed) — open in browser, click to
place polygon points on a Leaflet map, set `bufferKm`, copy the
generated `geo_filter` JSON block into `config.json`.

### scripts/prune-nodes-outside-geo-filter.py

Utility script to clean existing out-of-area nodes from the database
(dry-run + confirm). Useful after first enabling geo_filter on a
populated DB.

### HB column in packets table

Shows the hop hash size in bytes (1–4) decoded from the path byte of
each packet's raw hex. Displayed as **HB** between Size and Type
columns, hidden on small screens.

## Test plan

- [x] ADVERT from node outside polygon is not stored (no new row in
nodes or transmissions)
- [x] `GET /api/config/geo-filter` returns polygon + bufferKm when
configured, `{polygon: null, bufferKm: 0}` when not
- [x] `/api/nodes` excludes nodes outside polygon even if present in DB
- [x] Map and Live pages show blue polygon overlay when configured;
checkbox toggles it
- [x] `retention.packetDays: 30` deletes old transmissions/observations
on startup and daily
- [x] `POST /api/admin/prune?days=30` returns `{deleted: N, days: 30}`
- [x] `tools/geofilter-builder.html` opens standalone, draws polygon,
copies valid JSON
- [x] HB column shows 1–4 for all packets in grouped and flat view

Kpa-clawbot 5aa4fbb600 chore: normalize all files to LF line endings 2026-03-30 22:52:46 -07:00
Kpa-clawbot 93f85dee6e Add API key auth to Go write endpoints (#283)
## Summary
- added API key middleware for write routes in cmd/server/routes.go
- protected all current non-GET API routes (POST /api/packets, POST
/api/perf/reset, POST /api/decode)
- middleware enforces X-API-Key against cfg.APIKey and returns 401 JSON
error on missing/wrong key
- preserves backward compatibility: if piKey is empty, requests pass
through
- added startup warning log in cmd/server/main.go when no API key is
configured:
- [security] WARNING: no apiKey configured — write endpoints are
unprotected
- added route tests for missing/wrong/correct key and empty-apiKey
compatibility

## Validation
- cd cmd/server && go test ./... 

## Notes
- config.example.json already contains piKey, so no changes were
required.

Kpa-clawbot 77d8f35a04 feat: implement packet store eviction/aging to prevent OOM (#273)
## Summary

The in-memory `PacketStore` had **no eviction or aging** — it grew
unbounded until OOM killed the process. At ~3K packets/hour and ~5KB per
packet (not the 450 bytes previously estimated), an 8GB VM would OOM in
a few days.

## Changes

### Time-based eviction
- Configurable via `config.json`: `"packetStore": { "retentionHours": 24
}`
- Packets older than the retention window are evicted from the head of
the sorted slice

### Memory-based cap
- Configurable via `"packetStore": { "maxMemoryMB": 1024 }`
- Hard ceiling — evicts oldest packets when estimated memory exceeds the
cap

### Index cleanup
When a `StoreTx` is evicted, ALL associated data is removed from:
- `byHash`, `byTxID`, `byObsID`, `byObserver`, `byNode`, `byPayloadType`
- `nodeHashes`, `distHops`, `distPaths`, `spIndex`

### Periodic execution
- Background ticker runs eviction every 60 seconds
- Analytics caches and hash size cache are invalidated after eviction

### Stats fixes
- `estimatedMB` now uses ~5KB/packet + ~500B/observation (was 430B +
200B)
- `evicted` counter reflects actual evictions (was hardcoded to 0)
- Removed fake `maxPackets: 2386092` and `maxMB: 1024` from stats

### Config example
```json
{
  "packetStore": {
    "retentionHours": 24,
    "maxMemoryMB": 1024
  }
}
```

Both values default to 0 (unlimited) for backward compatibility.

## Tests
- 7 new tests in `eviction_test.go` covering time-based, memory-based,
index cleanup, thread safety, config parsing, and no-op when disabled
- All existing tests pass unchanged

Kpa-clawbot b326e3f1a6 fix: pprof port conflict crashed Go server — non-fatal bind + separate ports
Server defaults to 6060, ingestor to 6061. Removed shared PPROF_PORT
env var. Bind failure logs warning instead of log.Fatal killing the process.

Kpa-clawbot 6d31cb2ad6 feat: add pprof profiling controlled by ENABLE_PPROF env var
Add net/http/pprof support to both Go server (default port 6060) and
ingestor (default port 6061). Profiling is off by default — only
starts the pprof HTTP listener when ENABLE_PPROF=true.

PPROF_PORT env var overrides the default port for each binary.

Enable on staging-go in docker-compose with exposed ports 6060/6061.
Not enabled on prod.

Kpa-clawbot e300228874 perf: add TTL cache for subpaths API + build timestamp in stats/health
- Add 15s TTL cache to GetAnalyticsSubpaths with composite key (region|minLen|maxLen|limit),
  matching the existing cache pattern used by RF, topology, hash, channel, and distance analytics.
  Cache hits return instantly vs 900ms+ computation. fixes #168

- Add BuildTime to /api/stats and /api/health responses, injected via ldflags at build time.
  Dockerfile.go now accepts BUILD_TIME build arg. fixes #165

Kpa-clawbot 0d9b535451 feat: add version and git commit to /api/stats and /api/health
Node.js: reads version from package.json, commit from .git-commit file
or git rev-parse --short HEAD at runtime, with unknown fallback.

Go: uses -ldflags build-time variables (Version, Commit) with fallback
to .git-commit file and git command at runtime.

Dockerfile: copies .git-commit if present (CI bakes it before build).
Dockerfile.go: passes APP_VERSION and GIT_COMMIT as build args to ldflags.
deploy.yml: writes GITHUB_SHA to .git-commit before docker build steps.
docker-compose.yml: passes build args to Go staging build.

Tests updated to verify version and commit fields in both endpoints.

Kpa-clawbot afe16db960 feat(go-server): in-memory packet store — port of packet-store.js
Streams transmissions + observations from SQLite at startup into
5 indexed in-memory structures. QueryPackets and QueryGroupedPackets
now serve from RAM (<10ms) instead of hitting SQLite (2.3s).

- store.go: PacketStore with byHash, byTxID, byObsID, byObserver, byNode indexes
- main.go: create + load store at startup
- routes.go: dispatch to store for packet/stats endpoints
- websocket.go: poller ingests new transmissions into store

Kpa-clawbot b2e6c8105b fix: handle WebSocket upgrade at root path (client connects to ws://host/)
Node.js upgrades WS at /, Go was only at /ws. Now the static file
handler checks for Upgrade header first and routes to WebSocket.
