-# v3.6.0 - The Forensics
-
-CoreScope just got eyes everywhere. This release drops **path inspection**, **color-by-hash markers**, **clock skew detection**, **full channel encryption**, an **observer graph**, and a pile of robustness fixes that make your mesh network feel like it's being watched by someone who actually cares.
-
-134 commits, 105 PRs merged, 18K+ lines added. Here's what shipped.
-
----
-
-## 🚀 New Features
-
-### Path-Prefix Candidate Inspector (#944, #945)
-The marquee feature. Click any path segment and CoreScope opens an interactive inspector showing every candidate node that could match that hop prefix - plotted on a map with scoring by neighbor-graph affinity and geographic centroid. Ambiguous hops? Now you can see *why* they're ambiguous and pick the right one.
-
-**Why you'll love it:** No more guessing which `0xA3` is the real repeater. The inspector lays out every candidate, scores them, and lets you drill in visually.
-
-### Color-by-Hash Packet Markers (#948, #951)
-Every packet type gets a vivid, hash-derived color - on the live feed, map polylines, and flying-packet animations. Bright fill with dark outline for contrast. No more monochrome blobs - you can visually track packet flows by color at a glance.
-
-### Node Filter on Live Page (#924, #771)
-Filter the live packet stream to show only traffic flowing through a specific node. Pick a repeater, see exactly what it's carrying. That simple.
-
-### Clock Skew Detection (#746, #752, #828, #850)
-Full pipeline: backend computes drift using Theil-Sen regression with outlier rejection (#828), the UI shows per-node badges, detail sparklines, and fleet-wide analytics (#752). Bimodal clock severity (#850) surfaces flaky-RTC nodes that toggle between accurate and drifted - instead of hiding them as "No Clock."
-
-**Why you'll love it:** Nodes with bad clocks silently corrupt your timeline. Now they glow red before they ruin your analysis.
-
-### Observer Graph (M1+M2) (#774)
-Observers are now first-class graph citizens. CoreScope builds a neighbor graph from observation overlaps, scores hop-resolver candidates by graph edges (#876), and uses geographic centroid for tiebreaking. The observer topology is visible and queryable.
-
-### Channel Encryption - Full Stack (#726, #733, #750, #760)
-Three milestones landed as one: DB-backed channel message history (#726), client-side PSK decryption in the browser (#733), and PSK channel management with add/remove UX and message caching (#750). Add a channel key in the UI, and CoreScope decrypts messages client-side - no server-side key storage. The add-channel button (#760) makes it dead simple.
-
-**Why you'll love it:** Encrypted channels are no longer black boxes. Add your PSK, see the messages, search history - all without exposing keys to the server.
-
-### Hash Collision Inspector (#758)
-The Hash Usage Matrix now shows collision details for all hash sizes. When two nodes share a prefix, you see exactly who collides and at what size.
-
-### Geofilter Builder - In-App (#735, #900)
-The geofilter polygon builder is now served directly from CoreScope with a full docs page (#900). No more hunting for external tools. Link from the customizer, draw your polygon, done.
-
-### Node Blacklist (#742)
-`nodeBlacklist` in config hides abusive or troll nodes from all views. They're gone.
-
-### Observer Retention (#764)
-Stale observers are automatically pruned after a configurable number of days. Your observer list stays clean without manual intervention.
-
-### Advert Signature Validation (#794)
-Corrupt packets with invalid advert signatures are now rejected at ingest. Bad data never hits your store.
-
-### Bounded Cold Load (#790)
-`Load()` now respects a memory budget - no more OOM on cold start with a fat database. Combined with retention-hours cutoff (#917), cold start is safe on constrained hardware.
-
-### Multi-Arch Docker Images (#869)
-Official images now publish `amd64` + `arm64` in a single multi-arch manifest. Raspberry Pi operators: pull and run. No special tags needed.
-
-### /nodes Detail Panel + Search (#868)
-The nodes detail panel ships with search improvements (#862) - find nodes fast, see their full detail in a slide-out panel.
-
-### Deduplicated Top Longest Hops (#848)
-Longest hops are now deduplicated by pair with observation count and SNR cues. No more seeing the same link 47 times.
-
----
-
-## 🔥 Performance Wins
-
-### StoreTx ResolvedPath Elimination (#806)
-The per-transaction `ResolvedPath` computation is gone - replaced by a membership index with on-demand decode. This was one of the hottest paths in the ingestor.
-
-### Node Packet Queries (#803)
-Raw JSON text search for node packets replaced with a proper `byNode` index (#673). Night and day.
-
-### Channel Query Performance (#762, #763)
-New `channel_hash` column enables SQL-level channel filtering. No more full-table scan to find messages in a channel.
-
-### SQLite Auto-Vacuum (#919, #920)
-Incremental auto-vacuum enabled - the database file actually shrinks after retention pruning. No more 2GB database holding 200MB of live data.
-
-### Retention-Hours Cutoff on Load (#917)
-`Load()` now applies `retentionHours` at read time, preventing OOM when the DB has more history than memory allows.
-
----
-
-## 🛡️ Security & Robustness
-
-### MQTT Reconnect with Bounded Backoff (#947, #949)
-The ingestor now reconnects to MQTT brokers with exponential backoff, observability logging, and bounded retry. No more silent disconnects that kill your data stream.

-## 🐛 Bugs Squashed
-
-This release exterminates **40+ bugs** — from protocol-level hash mismatches to pixel-level CSS breakage. Operators told us what hurt; we listened.
-
-- **Path inspector "Show on Map" missed origin and first hop** (#950) - map view now includes all hops
-- **Content hash used full header byte** (#787) - content hashing now uses payload type bits only, fixing hash collisions between packets that differ only in header flags
-- **Encrypted channel deep links showed broken UI** (#825, #826, #815) - deep links to encrypted channels now show a lock message instead of broken UI when you don't have the key
-- **Geofilter longitude wrapping** (#925) - geofilter builder wraps longitude to [-180, 180]; southern hemisphere polygons no longer invert
-- **Hash filter bypasses saved region filter** (#939) - hash lookups now skip the geo filter as intended
-- **Companion-as-repeater excluded from path hops** (#935, #936) - non-repeater nodes no longer pollute hop resolution
-- **Customize panel re-renders while typing** (#927) - text fields keep focus during config changes
-- **Per-observation raw_hex** (#881, #882) - each observer's hex dump now shows what *that observer* actually received
-- **Per-observation children in packet groups** (#866, #880) - expanded groups show per-obs data, not cross-observer aggregates
-- **Full-page obs-switch** (#866, #870) - switching observers updates hex, path, and direction correctly
-- **Packet detail shows wrong observation** (#849, #851) - clicking a specific observation opens *that* observation
-- **Byte breakdown hop count** (#844, #846) - derived from `path_len`, not aggregated `_parsedPath`
-- **Transport-route path_len offset** (#852, #853) - correct offset calculation + CSS variable fix
-- **Packets/hour chart bars + x-axis** (#858, #865) - bars render correctly, x-axis labels properly decimated
-- **Channel timeline capped to top 8** (#860, #864) - no more 47-channel chart spaghetti
-- **Reachability row opacity removed** (#859, #863) - clean rows without misleading gradient
-- **Sticky table headers on mobile** (#861, #867) - restored after regression
-- **Map popup 'Show Neighbors' on iOS Safari** (#840, #841) - link actually works now
-- **Node detail Recent Packets invisible text** (#829, #830) - CSS fix
-- **/api/packets/{hash} falls back to DB** (#827, #831) - when in-memory store misses, DB catches it
-- **IATA filter bypass for status messages** (#694, #802) - status packets no longer filtered out by airport codes
-- **Desktop node click URL hash** (#676, #739) - clicking a node updates the URL for deep linking
-- **Filter params in URL hash** (#682, #740) - all filter state serialized for shareable links
-- **Hide undecryptable channel messages** (#727, #728) - clean default view
-- **TRACE path_json uses path_sz** (#732) - correct field from flags byte, not header hash_size
-- **Multi-byte adopters** (#754, #767) - all node types, role column, advert precedence
-- **Channel key case sensitivity** (#761) - Public decode works correctly
-- **Transport route field offsets** (#766) - correct offsets in field table
-- **Clock skew sanity checks** (#769) - filter epoch-0, cap drift, require minimum samples
-- **Neighbor graph slider persistence** (#776) - default 0.7, persisted to localStorage
-- **Node detail panel navigation** (#779, #785) - Details/Analytics links actually navigate
-- **Channel key removal** (#898) - user-added keys for server-known channels can be removed
-- **Side-panel Details on desktop** (#892) - opens full-screen correctly
-- **Hex-dump byte ranges client-side** (#891) - computed from per-obs raw_hex
-- **path_json derived from raw_hex at ingest** (#886, #887) - single source of truth
-- **Path pill and byte breakdown hop agreement** (#885) - they match now
-- **Mobile close button + toolbar scroll** (#797, #805) - accessible and scrollable
-- **/health.recentPackets resolved_path fallback** (#810, #821) - falls back to longest sibling observation
-- **Channel filter on Packets page** (#812, #816) - UI and API both fixed
-- **Clock-skew section in side panel** (#813, #814) - renders correctly
-- **Real RSS in /api/stats** (#832, #835) - surface actual RSS alongside tracked store bytes
-- **Hash size detection for transport routes + zero-hop adverts** (#747) - correct detection

-// Scenario from #804:
-//   - PDX-Repeater is a multi-byte (hashSize=2) repeater whose ZERO-HOP direct
-//     adverts are only heard by obs-PDX (a PDX observer). That zero-hop direct

-//   - A flood advert from PDX-Repeater (hashSize=2) propagates and is heard by
-//     obs-SJC (a SJC observer) via a multi-hop relay path.
-//   - When the user asks for region=SJC analytics, the PDX-Repeater MUST NOT
-//     pollute SJC's multiByteNodes — it lives in PDX.
-//   - The result should also expose attributionMethod="repeater" so the API
-//     consumer knows which method was used.
-//

-**Issue**: Kpa-clawbot/CoreScope#899  
-**Date**: 2026-04-23  
-**Branch target**: `master`
-
----
-
-## Overview
-
-Add a dedicated **Scopes** page showing scope/region statistics for MeshCore transport-route packets. Scope filtering in MeshCore uses `TRANSPORT_FLOOD` (route_type 0) and `TRANSPORT_DIRECT` (route_type 3) packets that carry two 16-bit transport codes. Code1 ≠ `0000` means the packet is region-scoped.
-
-Feature 3 from the issue (default scope per client via advert) is **not implemented** — the advert format has no scope field in the current firmware.
-
----
-
-## How Scopes Work (Firmware)
-
-Transport code derivation (authoritative source: `meshcore-dev/MeshCore`):
-
-```
-key  = SHA256("#regionname")[:16]          // TransportKeyStore::getAutoKeyFor
-Code1 = HMAC-SHA256(key, type || payload)  // TransportKey::calcTransportCode, 2-byte output
-```
-
-Code1 is a **per-message** HMAC — the same region produces a different Code1 for every message. Identifying a region from Code1 requires knowing the region name in advance and recomputing the HMAC.
-
-`Code1 = 0000` is the "no scope" sentinel (also `FFFF` is reserved). Packets with route_type 1 or 2 (plain FLOOD/DIRECT) carry no transport codes.
-
----
-
-## Config
-
-Add `hashRegions` to the ingestor `Config` struct in `cmd/ingestor/config.go`, mirroring `hashChannels`:
-
-```json
-"hashRegions": ["#belgium", "#eu", "#brussels"]
-```
-
-Normalization (same rules as `hashChannels`):
-- Trim whitespace
-- Prepend `#` if missing
-- Skip empty entries
-
----
-
-## Ingestor Changes
-
-### Key derivation (`loadRegionKeys`)
-
-```go
-func loadRegionKeys(cfg *Config) map[string][]byte {
-    // key = first 16 bytes of SHA256("#regionname")
-}
-```
-
-Returns `map[string][]byte` (region name → 16-byte HMAC key). Called once at startup, stored on the `Store`.
-
-### Decoder: expose raw payload bytes
-
-Add `PayloadRaw []byte` to `DecodedPacket` in `cmd/ingestor/decoder.go`. Populated from the raw `buf` slice at the payload offset — zero-copy slice, no allocation. This is the **encrypted** payload bytes, matching what the firmware feeds into `calcTransportCode`.
-
-### At-ingest region matching
-
-In `BuildPacketData`:
-- Skip if `route_type` not in `{0, 3}` → `scope_name` stays `nil`
-- If `Code1 == "0000"` → `scope_name = nil` (unscoped transport, no scope involvement)
-- If `Code1 != "0000"` → try each region key:
-  ```
-  HMAC-SHA256(key, payloadType_byte || PayloadRaw)  → first 2 bytes as uint16
-  ```
-  First match → `scope_name = "#regionname"`. No match → `scope_name = ""` (unknown scope).
-
-Add `ScopeName *string` to `PacketData`.
-
-### MQTT-sourced packets (DM / CHAN paths in main.go)
-
-These are injected directly without going through `BuildPacketData`. They use `route_type = 1` (FLOOD), so they are never transport-route packets. No scope matching needed for these paths.
-
----
-
-## Database
-
-### Migration
-
-```sql
-ALTER TABLE transmissions ADD COLUMN scope_name TEXT DEFAULT NULL;
-CREATE INDEX idx_tx_scope_name ON transmissions(scope_name) WHERE scope_name IS NOT NULL;
-```
-
-### Column semantics
-
-| Value | Meaning |
-|-------|---------|
-| `NULL` | Either: non-transport-route packet (route_type 1/2), or transport-route with Code1=0000 |
-| `""` (empty string) | Transport-route, Code1 ≠ 0000, but no configured region matched |
-| `"#belgium"` | Matched named region |
-
-The API stats queries resolve the NULL ambiguity by always filtering `route_type IN (0, 3)` first:
-- `unscoped` count = `route_type IN (0,3) AND scope_name IS NULL`
-- `scoped` count = `route_type IN (0,3) AND scope_name IS NOT NULL`
-
-### Backfill
-
-On migration, re-decode `raw_hex` for all rows where `route_type IN (0, 3)` and `scope_name IS NULL`. Run the same HMAC matching logic. Rows with `Code1 = 0000` remain `NULL`.
-
-The backfill runs in the existing migration framework in `cmd/ingestor/db.go`. If no regions are configured, backfill is skipped.
-
----
-
-## API
-
-### `GET /api/scope-stats`
-
-**Query param**: `window` — one of `1h`, `24h` (default), `7d`
-
-**Time-series bucket sizes**:
-| Window | Bucket |
-|--------|--------|
-| `1h`   | 5 min  |
-| `24h`  | 1 hour |
-| `7d`   | 6 hours|
-
-**Response**:
-```json
-{
-  "window": "24h",
-  "summary": {
-    "transportTotal": 1240,
-    "scoped": 890,
-    "unscoped": 350,
-    "unknownScope": 42
-  },
-  "byRegion": [
-    { "name": "#belgium", "count": 612 },
-    { "name": "#eu",      "count": 236 }
-  ],
-  "timeSeries": [
-    { "t": "2026-04-23T10:00:00Z", "scoped": 45, "unscoped": 18 },
-    { "t": "2026-04-23T11:00:00Z", "scoped": 51, "unscoped": 22 }
-  ]
-}
-```
-
-- `transportTotal` = `scoped + unscoped` (transport-route packets only)
-- `scoped` = Code1 ≠ 0000 (named + unknown)
-- `unscoped` = transport-route with Code1 = 0000
-- `unknownScope` = scoped but no region name matched (subset of `scoped`)
-- `byRegion` sorted by count descending, excludes unknown
-- `timeSeries` covers the full window at the bucket granularity
-
-Route: `GET /api/scope-stats` registered in `cmd/server/routes.go`.  
-No auth required (same as other read endpoints).  
-TTL cache: 30 seconds (heavier query than `/api/stats`).
-
----
-
-## Frontend
-
-### Navigation
-
-Add nav link between Channels and Nodes in `public/index.html`:
-```html
-<a href="#/scopes" class="nav-link" data-route="scopes">Scopes</a>
-```
-
-### `public/scopes.js`
-
-Three sections on the page:
-
-**1. Summary cards** (reuse existing card CSS pattern from home/analytics pages)  
-- Transport total, Scoped, Unscoped, Unknown scope  
-- Each card shows count + percentage of transport total
-
-**2. Per-region table**  
-Columns: Region, Messages, % of Scoped  
-Sorted by count descending. Last row: "Unknown scope" (italic) if unknownScope > 0.  
-Shows "No regions configured" message if `byRegion` is empty and `unknownScope = 0`.
-
-**3. Time-series chart**  
-- Window selector: `1h / 24h / 7d` (default 24h)  
-- Two lines: **Scoped** (blue) and **Unscoped** (grey)  
-- Uses the same lightweight canvas chart pattern as other pages (no external chart lib)
-
-### Cache buster
-
-`scopes.js` added to the `__BUST__` entries in `index.html` in the same commit.
-
----
-
-## Testing
-
-- Unit tests for `loadRegionKeys`: normalization, key bytes match firmware SHA256 derivation
-- Unit tests for HMAC matching: known Code1 value computed from firmware logic, verified against Go implementation
-- Integration test: ingest a synthetic transport-route packet with a known region, assert `scope_name` column is set correctly
-- API test: `GET /api/scope-stats` returns correct summary counts against fixture DB
-
----
-
-## Out of Scope
-
-- Feature 3 (default scope per client via advert) — firmware has no advert scope field
-- Drill-down from region row to filtered packet list (deferred)
-- Private regions (`$`-prefixed) — use secret keys not publicly derivable

-# Database
-
-CoreScope uses SQLite in WAL (Write-Ahead Log) mode for both the server
-(read-only) and ingestor (read-write).
-
-## WAL mode
-
-WAL mode allows concurrent reads while writes happen. It is set automatically
-at connection time via `PRAGMA journal_mode=WAL`. No operator action needed.
-
-The WAL file (`meshcore.db-wal`) grows during writes and is checkpointed
-(merged back into the main DB) periodically and at clean shutdown.
-
-## Auto-vacuum
-
-By default, SQLite does not shrink the database file after `DELETE` operations.
-Deleted pages are marked free and reused by future writes, but the file size
-on disk stays the same. This is surprising when lowering retention settings.
-
-### New databases
-
-Databases created after this feature was added automatically have
-`PRAGMA auto_vacuum = INCREMENTAL`. After each retention reaper cycle,
-CoreScope runs `PRAGMA incremental_vacuum(N)` to return free pages to the OS.
-
-### Existing databases
-
-The `auto_vacuum` mode is stored in the database header and can only be changed
-by rewriting the entire file with `VACUUM`. CoreScope will **not** do this
-automatically — on large databases (5+ GB seen in the wild) it takes minutes
-and holds an exclusive lock.
-
-**To migrate an existing database:**
-
-1. At startup, CoreScope logs a warning:
-   ```
-   [db] auto_vacuum=NONE — DB needs one-time VACUUM to enable incremental auto-vacuum.
-   ```
-2. **Ensure at least 2× the database file size in free disk space.** Full VACUUM
-   creates a temporary copy of the entire file — on a near-full disk it will fail.
-3. Set `db.vacuumOnStartup: true` in your `config.json`:
-   ```json
-   {
-     "db": {
-       "vacuumOnStartup": true
-     }
-   }
-   ```
-4. Restart CoreScope. The one-time `VACUUM` will run and block startup.
-5. After migration, remove or set `vacuumOnStartup: false` — it's not needed again.
-
-### Configuration
-
-| Field | Default | Description |
-|-------|---------|-------------|
-| `db.vacuumOnStartup` | `false` | One-time full VACUUM to enable incremental auto-vacuum |
-| `db.incrementalVacuumPages` | `1024` | Pages returned to OS per reaper cycle |
-
-## Manual VACUUM
-
-You can also run a manual vacuum from the SQLite CLI:
-
-```bash
-sqlite3 data/meshcore.db "PRAGMA auto_vacuum = INCREMENTAL; VACUUM;"
-```
-
-This is equivalent to `vacuumOnStartup: true` but can be done offline.
-
-> ⚠️ Full VACUUM requires **2× the database file size** in free disk space (it
-> creates a temporary copy). Check with `ls -lh data/meshcore.db` before running.
-
-## Checking current mode
-
-```bash
-sqlite3 data/meshcore.db "PRAGMA auto_vacuum;"
-```
-
-- `0` = NONE (default for old databases)
-- `1` = FULL (automatic, but slower writes)
-- `2` = INCREMENTAL (recommended — CoreScope triggers vacuum after deletes)
-
-See [#919](https://github.com/Kpa-clawbot/CoreScope/issues/919) for background on this feature.

-<main>
-
-<h2>How it works</h2>
-<p>Geographic filtering restricts which nodes are ingested and returned in API responses. It operates at two levels:</p>
-<ul>
-  <li><strong>Ingest time</strong> — ADVERT packets carrying GPS coordinates are rejected by the ingestor if the node falls outside the configured area. The node never reaches the database.</li>
-  <li><strong>API responses</strong> — Nodes already in the database are filtered from the <code>/api/nodes</code> response if they fall outside the area. This covers nodes ingested before the filter was configured.</li>
-</ul>
-<div class="note"><p>Nodes with no GPS fix (<code>lat=0, lon=0</code> or missing coordinates) always pass the filter regardless of configuration.</p></div>
-
-<h2>Configuration</h2>
-<p>Add a <code>geo_filter</code> block to <code>config.json</code>:</p>
-<pre><code>"geo_filter": {
-  "polygon": [
-    [51.55, 3.80],
-    [51.55, 5.90],
-    [50.65, 5.90],
-    [50.65, 3.80]
-  ],
-  "bufferKm": 20
-}</code></pre>
-<table>
-  <thead><tr><th>Field</th><th>Type</th><th>Description</th></tr></thead>
-  <tbody>
-    <tr><td><code>polygon</code></td><td><code>[[lat, lon], ...]</code></td><td>Array of at least 3 coordinate pairs defining the boundary</td></tr>
-    <tr><td><code>bufferKm</code></td><td>number</td><td>Extra distance (km) around the polygon edge that is also accepted. <code>0</code> = exact boundary</td></tr>
-  </tbody>
-</table>
-<p>Both the server and the ingestor read <code>geo_filter</code> from <code>config.json</code>. Restart both after changing this section.</p>
-<p>To disable filtering entirely, remove the <code>geo_filter</code> block.</p>
-
-<h2>Builder workflow: Save Draft, Load Draft, Download</h2>
-<p>The <a href="/geofilter-builder.html">GeoFilter Builder</a> lets you draw a polygon on a map and produce the <code>geo_filter</code> snippet without hand-editing JSON. Three buttons drive the workflow:</p>
-<ul>
-  <li><strong>💾 Save Draft</strong> — writes the current polygon and <code>bufferKm</code> to your browser's <code>localStorage</code> under the key <code>geofilter-draft</code>. Drafts persist across page reloads and browser restarts so you can iterate on a shape over multiple sessions.</li>
-  <li><strong>📂 Load Draft</strong> — restores the most recently saved draft into the builder. The current polygon is replaced. If no draft exists the button is a no-op.</li>
-  <li><strong>⬇ Download</strong> — exports the current polygon and <code>bufferKm</code> as <code>geofilter-config-snippet.json</code> — a single JSON object containing a top-level <code>geo_filter</code> block. Open the file, copy the <code>geo_filter</code> entry, and paste it into your <code>config.json</code>.</li>
-</ul>
-<div class="note"><p>Drafts are stored locally in your browser only — they are not uploaded anywhere. Clearing site data or switching browsers will lose the draft. Use <strong>Download</strong> to keep a portable copy.</p></div>
-<p>After pasting the snippet into <code>config.json</code>, restart the server and ingestor for the new filter to take effect.</p>
-
-<h2>Coordinate ordering</h2>
-<div class="warn"><p><strong>Important:</strong> Coordinates are <code>[lat, lon]</code> — latitude first, longitude second. This is the opposite of GeoJSON, which uses <code>[lon, lat]</code>. Swapping them will place your polygon in the wrong location.</p></div>
-
-<h2>Multi-polygon</h2>
-<p>Only a single polygon is supported. If your deployment area consists of multiple disconnected regions, draw a single convex hull that covers all of them, or use the largest region with a generous <code>bufferKm</code> value.</p>
-
-<h2>Examples</h2>
-<h3>Belgium (bounding rectangle)</h3>
-<pre><code>"geo_filter": {
-  "polygon": [
-    [51.55, 3.80],
-    [51.55, 5.90],
-    [50.65, 5.90],
-    [50.65, 3.80]
-  ],
-  "bufferKm": 20
-}</code></pre>
-<h3>Irregular shape</h3>
-<pre><code>"geo_filter": {
-  "polygon": [
-    [51.10, 3.70],
-    [51.55, 4.20],
-    [51.30, 5.10],
-    [50.80, 5.50],
-    [50.50, 4.80],
-    [50.70, 3.90]
-  ],
-  "bufferKm": 10
-}</code></pre>
-
-<h2>Legacy bounding box</h2>
-<p>An older bounding box format is also supported as a fallback when no <code>polygon</code> is present:</p>
-<pre><code>"geo_filter": {
-  "latMin": 50.65,
-  "latMax": 51.55,
-  "lonMin": 3.80,
-  "lonMax": 5.90
-}</code></pre>
-<p>Prefer the polygon format — it supports irregular shapes and the <code>bufferKm</code> margin.</p>
-
-<h2>Cleaning up historical nodes</h2>
-<p>The ingestor prevents new out-of-bounds nodes from being ingested, but does not retroactively remove nodes stored before the filter was configured. Use the prune script for that:</p>
-<pre><code># Dry run — shows what would be deleted without making any changes
-python3 scripts/prune-nodes-outside-geo-filter.py --dry-run
-
-# Default paths: /app/data/meshcore.db and /app/config.json
-python3 scripts/prune-nodes-outside-geo-filter.py
-
-# Custom paths
-python3 scripts/prune-nodes-outside-geo-filter.py /path/to/meshcore.db \
-  --config /path/to/config.json
-
-# In Docker — run inside the container
-docker exec -it meshcore-analyzer \
-  python3 /app/scripts/prune-nodes-outside-geo-filter.py --dry-run</code></pre>
-<p>The script reads <code>geo_filter.polygon</code> and <code>geo_filter.bufferKm</code> from config, lists nodes that fall outside, then asks for <code>yes</code> confirmation before deleting. Nodes without coordinates are always kept.</p>
-<p>This is a one-time migration tool — run it once after first configuring <code>geo_filter</code> to clean up pre-filter data.</p>

- * in **secure contexts** (HTTPS or localhost). When CoreScope is served
- * over plain HTTP — common for self-hosted instances and LAN-side
- * deployments — `crypto.subtle` is undefined and any

- * SHA-256 / HMAC paths used by `computeChannelHash` and `verifyMAC`.
- *
- * Implementation: textbook FIPS-180-4 SHA-256 + RFC 2104 HMAC. Operates
- * on Uint8Array inputs; returns Uint8Array outputs. ~120 LOC, no deps.

- * Tests for AES-128-ECB decryption in public/channel-decrypt.js.
- *
- * Background: the original implementation simulated ECB via Web Crypto
- * AES-CBC with a zero IV and a dummy PKCS7 padding block. Web Crypto
- * validates PKCS7 padding on the decrypted output and throws an
- * `OperationError` whenever the last 16 bytes of the (CBC-decrypted)
- * output don't form a valid PKCS7 padding sequence — which is the

- * second block. This test pins decryptECB() to the FIPS-197 NIST
- * AES-128-ECB known-answer vector (Appendix B / C.1) so that the

- * origin like `http://<lan-ip>:8080`), browsers refuse to expose

- * pinned to `crypto.subtle`. Result on HTTP origins:
- *
- *   addUserChannel("372a9c93260507adcbf36a84bec0f33d")
- *     -> computeChannelHash(key) throws "Cannot read properties of undefined

-/**
- * Regression test: live PSK decrypt for user-added channels (#1029 follow-up).
- *
- * PR #1030 added decryptLivePSKBatch() which rewrites encrypted GRP_TXT
- * WS packets in place when a stored PSK key matches. It sets
- *   payload.channel = dec.channelName  (e.g. "medusa")
- * but user-added channels are stored in channels[] with hash:
- *   "user:medusa"
- * (and selectedHash is also "user:medusa" when viewing).
- *
- * Symptoms in production:
- *  - selectedHash === "user:medusa" but processWSBatch compares
- *    `channelName === selectedHash` ("medusa" !== "user:medusa") so a live
- *    packet for the open channel is NEVER appended to the message list.
- *  - channels.find(c => c.hash === channelName) misses the user channel and
- *    a duplicate plain entry "medusa" is pushed into the sidebar; the real
- *    user-added channel's lastMessage / messageCount / lastActivityMs never
- *    update.
- *  - The unread bumper guards with `chName === prior` (raw name vs prefixed
- *    selectedHash), so an unread badge is added even when the user IS
- *    actively viewing that channel.
- *
- * Fix: have the live decrypt rewrite annotate the payload with the
- * canonical channel hash that channels[] / selectedHash use. A simple,
- * non-breaking shape: keep payload.channel = name (so the rest of
- * processWSBatch keeps working for non-user channels), AND also set
- * payload.channelKey = "user:" + name when a user-added channel exists for
- * that name. processWSBatch then uses channelKey when present for the
- * lookup + selectedHash comparison.
- *
- * This test loads the real channels.js in a vm sandbox, primes a
- * user-added channel, drives an encrypted GRP_TXT through the WS handler
- * and asserts:
- *   1. the open channel's message list grows by 1 (text is decrypted-locally
- *      and visible in the messages array)
- *   2. the user-added channel's messageCount / lastMessage update
- *   3. NO duplicate plain "medusa" entry is added to channels[]
- *   4. unread is NOT bumped on the channel currently being viewed

-/**
- * Tests for live PSK decrypt on WebSocket-delivered GRP_TXT packets.
- *
- * Bug: when a user has a stored PSK key for a channel and a new encrypted
- * GRP_TXT packet arrives via the WebSocket feed, the existing UI path
- * leaves it as an encrypted blob and only renders sender="Unknown" with
- * empty text. The user has to refresh the page to get the message decrypted
- * via the REST fetch path.
- *
- * Fix:
- *   - ChannelDecrypt.buildKeyMap()    -> Map<hashByte, { channelName, keyBytes, keyHex }>
- *   - ChannelDecrypt.tryDecryptLive(payload, keyMap)
- *       For GRP_TXT payloads with encryptedData/mac/channelHash matching
- *       a stored key, returns { sender, text, channelName, channelHashByte }.
- *       Returns null when no key matches or when MAC verification fails.
- *   - channels.js processWSBatch() uses these to upgrade encrypted live
- *     packets in-place before rendering, and bumps an unread badge for
- *     channels the user is not currently viewing.
