index fixups for the prod DB

controller: collapse duplicate OTel spans on the request path
Reduce spans emitted per controller request without touching the head sample rate. Removes 20 StartSpan sites (97 -> 77) that traced the same logical op at multiple layers: - DB.cpp: drop all db:: read-helper/leaf spans; the db_mirror_set:: wrapper survives as the single span per read op (also removes the latent member_id-from-networkId attribute bug). - CentralDB.cpp: drop inner write-op spans (save/+children, nodeIsOnline, eraseNetwork, eraseMember); keep getSSOAuthInfo (errors) and all background-thread spans (commitThread, onlineNotificationThread, init). - EmbeddedNetworkController.cpp: drop per-rule parseRule span and the no-op _startThreads span; keep request/_request roots. Sampler, trace-context propagation, commit/Bigtable-write spans, and all business logic are unchanged.

+2. License Grants and Conditions
+--------------------------------
+
+2.1. Grants
+
+Each Contributor hereby grants You a world-wide, royalty-free,
+non-exclusive license:
+
+(a) under intellectual property rights (other than patent or trademark)
+    Licensable by such Contributor to use, reproduce, make available,
+    modify, display, perform, distribute, and otherwise exploit its
+    Contributions, either on an unmodified basis, with Modifications, or
+    as part of a Larger Work; and
+
+(b) under Patent Claims of such Contributor to make, use, sell, offer
+    for sale, have made, import, and otherwise transfer either its
+    Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+The licenses granted in Section 2.1 with respect to any Contribution
+become effective for each Contribution on the date the Contributor first
+distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under
+this License. No additional rights or licenses will be implied from the
+distribution or licensing of Covered Software under this License.
+Notwithstanding Section 2.1(b) above, no patent license is granted by a
+Contributor:
+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+*  Covered Software is provided under this License on an "as is"       *
+*  basis, without warranty of any kind, either expressed, implied, or  *
+*  statutory, including, without limitation, warranties that the       *
+*  Covered Software is free of defects, merchantable, fit for a        *
+*  particular purpose or non-infringing. The entire risk as to the     *
+*  quality and performance of the Covered Software is with You.        *
+*  Should any Covered Software prove defective in any respect, You     *
+*  (not any Contributor) assume the cost of any necessary servicing,   *
+*  repair, or correction. This disclaimer of warranty constitutes an   *
+*  essential part of this License. No use of any Covered Software is   *
+*  authorized under this License except under this disclaimer.         *
+*                                                                      *

+*  Under no circumstances and under no legal theory, whether tort      *
+*  (including negligence), contract, or otherwise, shall any           *
+*  Contributor, or anyone who distributes Covered Software as          *

+*  including, without limitation, damages for lost profits, loss of    *

+*  extent applicable law prohibits such limitation. Some               *
+*  jurisdictions do not allow the exclusion or limitation of           *
+*  incidental or consequential damages, so this exclusion and          *

+************************************************************************
+
+8. Litigation
+-------------
+
+Any litigation relating to this License may be brought only in the
+courts of a jurisdiction where the defendant maintains its principal
+place of business and such litigation shall be governed by laws of that
+jurisdiction, without reference to its conflict-of-law provisions.
+Nothing in this Section shall prevent a party's ability to bring
+cross-claims or counter-claims.
+
+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent
+necessary to make it enforceable. Any law or regulation which provides
+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.
+
+10. Versions of the License
+---------------------------
+
+10.1. New Versions
+
+Mozilla Foundation is the license steward. Except as provided in Section
+10.3, no one other than the license steward has the right to modify or

+10.3. Modified Versions
+
+If you create software not governed by this License, and you want to
+create a new license for such software, you may create and use a
+modified version of this License if you rename the license and remove
+any references to the name of the license steward (except to note that
+such modified license differs from this License).

+## About

 ZeroTier is a smart programmable Ethernet switch for planet Earth. It allows all networked devices, VMs, containers, and applications to communicate as if they all reside in the same physical data center or cloud region.

-This is accomplished by combining a cryptographically addressed and secure peer to peer network (termed VL1) with an Ethernet emulation layer somewhat similar to VXLAN (termed VL2). Our VL2 Ethernet virtualization layer includes advanced enterprise SDN features like fine grained access control rules for network micro-segmentation and security monitoring.

-All ZeroTier traffic is encrypted end-to-end using secret keys that only you control. Most traffic flows peer to peer, though we offer free (but slow) relaying for users who cannot establish peer to peer connections.

See [AUTHORS.md](AUTHORS.md) for a list of third party code, where it is included, and the licenses that apply to it. All of the third party code in ZeroTier is liberally licensed (MIT, BSD, Apache, public domain, etc.).
+See [LICENSE-MPL.txt](LICENSE-MPL.txt) for all code in node/, osdep/. service/, and everywhere else except ext/ and nonfree/.

-### Getting Started
+See [nonfree/LICENSE.md](nonfree/LICENSE.md) for all non-free ("source available") portions of this repository.

-Everything in the ZeroTier world is controlled by two types of identifier: 40-bit/10-digit *ZeroTier addresses* and 64-bit/16-digit *network IDs*. These identifiers are easily distinguished by their length. A ZeroTier address identifies a node or "device" (laptop, phone, server, VM, app, etc.) while a network ID identifies a virtual Ethernet network that can be joined by devices.
-
-ZeroTier addresses can be thought of as port numbers on an enormous planet-wide enterprise Ethernet smart switch supporting VLANs. Network IDs are VLAN IDs to which these ports may be assigned. A single port can be assigned to more than one VLAN.
-
-A ZeroTier address looks like `8056c2e21c` and a network ID looks like `8056c2e21c000001`. Network IDs are composed of the ZeroTier address of that network's primary controller and an arbitrary 24-bit ID that identifies the network on this controller. Network controllers are roughly analogous to SDN controllers in SDN protocols like [OpenFlow](https://en.wikipedia.org/wiki/OpenFlow), though as with the analogy between VXLAN and VL2 this should not be read to imply that the protocols or design are the same. You can use our convenient and inexpensive SaaS hosted controllers at [my.zerotier.com](https://my.zerotier.com/) or [run your own controller](controller/) if you don't mind messing around with JSON configuration files or writing scripts to do so.
-
-### Project Layout
-
-The base path contains the ZeroTier One service main entry point (`one.cpp`), self test code, makefiles, etc.
-
- - `artwork/`: icons, logos, etc.
- - `attic/`: old stuff and experimental code that we want to keep around for reference.
- - `controller/`: the reference network controller implementation, which is built and included by default on desktop and server build targets.
- - `debian/`: files for building Debian packages on Linux.
- - `doc/`: manual pages and other documentation.
- - `ext/`: third party libraries, binaries that we ship for convenience on some platforms (Mac and Windows), and installation support files.
- - `include/`: include files for the ZeroTier core.
- - `java/`: a JNI wrapper used with our Android mobile app. (The whole Android app is not open source but may be made so in the future.)
- - `node/`: the ZeroTier virtual Ethernet switch core, which is designed to be entirely separate from the rest of the code and able to be built as a stand-alone OS-independent library. Note to developers: do not use C++11 features in here, since we want this to build on old embedded platforms that lack C++11 support. C++11 can be used elsewhere.
- - `osdep/`: code to support and integrate with OSes, including platform-specific stuff only built for certain targets.
- - `rule-compiler/`: JavaScript rules language compiler for defining network-level rules.
- - `service/`: the ZeroTier One service, which wraps the ZeroTier core and provides VPN-like connectivity to virtual networks for desktops, laptops, servers, VMs, and containers.
- - `windows/`: Visual Studio solution files, Windows service code, and the Windows task bar app UI.
- - `zeroidc/`: OIDC implementation used by ZeroTier service to log into SSO-enabled networks. (This part is written in Rust, and more Rust will be appearing in this repository in the future.)

-### Build and Platform Notes
-
-To build on Mac and Linux just type `make`. On FreeBSD and OpenBSD `gmake` (GNU make) is required and can be installed from packages or ports. For Windows there is a Visual Studio solution in `windows/`.
-
- - **Mac**
-   - Xcode command line tools for macOS 10.13 or newer are required.
-   - Rust for x86_64 and ARM64 targets *if SSO is enabled in the build*.
- - **Linux**
-   - The minimum compiler versions required are GCC/G++ 8.x or CLANG/CLANG++ 5.x.
-   - Linux makefiles automatically detect and prefer clang/clang++ if present as it produces smaller and slightly faster binaries in most cases. You can override by supplying CC and CXX variables on the make command line.
-   - Rust for x86_64 and ARM64 targets *if SSO is enabled in the build*.
- - **Windows**
-   - Visual Studio 2022 on Windows 10 or newer.
-   - Rust for x86_64 and ARM64 targets *if SSO is enabled in the build*.
- - **FreeBSD**
-   - GNU make is required. Type `gmake` to build.
-   - `binutils` is required.  Type `pkg install binutils` to install.
-   - Rust for x86_64 and ARM64 targets *if SSO is enabled in the build*.
- - **OpenBSD**
-   - There is a limit of four network memberships on OpenBSD as there are only four tap devices (`/dev/tap0` through `/dev/tap3`).
-   - GNU make is required. Type `gmake` to build.
-   - Rust for x86_64 and ARM64 targets *if SSO is enabled in the build*.
-
-Typing `make selftest` will build a *zerotier-selftest* binary which unit tests various internals and reports on a few aspects of the build environment. It's a good idea to try this on novel platforms or architectures.
-
-### Running
-
-Running *zerotier-one* with `-h` option will show help.
-
-On Linux and BSD, if you built from source, you can start the service with:
-
-    sudo ./zerotier-one -d
-
-On most distributions, macOS, and Windows, the installer will start the service and set it up to start on boot.
-
-A home folder for your system will automatically be created.
-
-The service is controlled via the JSON API, which by default is available at `127.0.0.1:9993`. It also listens on `0.0.0.0:9993` which is only usable if `allowManagementFrom` is properly configured in `local.conf`. We include a *zerotier-cli* command line utility to make API calls for standard things like joining and leaving networks. The *authtoken.secret* file in the home folder contains the secret token for accessing this API. See [service/README.md](service/README.md) for API documentation.
-
-Here's where home folders live (by default) on each OS:
-
- * **Linux**: `/var/lib/zerotier-one`
- * **FreeBSD** / **OpenBSD**: `/var/db/zerotier-one`
- * **Mac**: `/Library/Application Support/ZeroTier/One`
- * **Windows**: `\ProgramData\ZeroTier\One` (That's the default. The base 'shared app data' folder might be different if Windows is installed with a non-standard drive letter assignment or layout.)
-
-### Basic Troubleshooting
-
-For most users, it just works.
-
-If you are running a local system firewall, we recommend adding a rules permitting zerotier. If you installed binaries for Windows this should be done automatically. Other platforms might require manual editing of local firewall rules depending on your configuration.
-
-See the [documentation site](https://docs.zerotier.com/zerotier/troubleshooting) for more information.
-
-The Mac firewall can be found under "Security" in System Preferences. Linux has a variety of firewall configuration systems and tools.
-
-On CentOS check `/etc/sysconfig/iptables` for IPTables rules. For other distributions consult your distribution's documentation. You'll also have to check the UIs or documentation for commercial third party firewall applications like Little Snitch (Mac), McAfee Firewall Enterprise (Windows), etc. if you are running any of those. Some corporate environments might have centrally managed firewall software, so you might also have to contact IT.
-
-ZeroTier One peers will automatically locate each other and communicate directly over a local wired LAN *if UDP port 9993 inbound is open*. If that port is filtered, they won't be able to see each others' LAN announcement packets. If you're experiencing poor performance between devices on the same physical network, check their firewall settings. Without LAN auto-location peers must attempt "loopback" NAT traversal, which sometimes fails and in any case requires that every packet traverse your external router twice.
-
-Users behind certain types of firewalls and "symmetric" NAT devices may not be able to connect to external peers directly at all. ZeroTier has limited support for port prediction and will *attempt* to traverse symmetric NATs, but this doesn't always work. If P2P connectivity fails you'll be bouncing UDP packets off our relay servers resulting in slower performance. Some NAT router(s) have a configurable NAT mode, and setting this to "full cone" will eliminate this problem. If you do this you may also see a magical improvement for things like VoIP phones, Skype, BitTorrent, WebRTC, certain games, etc., since all of these use NAT traversal techniques similar to ours.
-
-If a firewall between you and the Internet blocks ZeroTier's UDP traffic, you will fall back to last-resort TCP tunneling to rootservers over port 443 (https impersonation). This will work almost anywhere but is *very slow* compared to UDP or direct peer to peer connectivity.
-
-Additional help can be found in our [knowledge base](https://zerotier.atlassian.net/wiki/spaces/SD/overview).
-
-### Prometheus Metrics
-
-Prometheus Metrics are available at the `/metrics` API endpoint.  This endpoint is protected by an API key stored in `metricstoken.secret` to prevent unwanted information leakage.  Information that could be gleaned from the metrics include joined networks and peers your instance is talking to. 
-
-Access control is via the ZeroTier control interface itself and `metricstoken.secret`. This can be sent as a bearer auth token, via the `X-ZT1-Auth` HTTP header field, or appended to the URL as `?auth=<token>`. You can see the current metrics via `cURL` with the following command:
-
-    // Linux
-    curl -H "X-ZT1-Auth: $(sudo cat /var/lib/zerotier-one/metricstoken.secret)" http://localhost:9993/metrics
-
-    // macOS
-    curl -H "X-ZT1-Auth: $(sudo cat /Library/Application\ Support/ZeroTier/One/metricstoken.secret)" http://localhost:9993/metrics
-
-    // Windows PowerShell (Admin)
-    Invoke-RestMethod -Headers @{'X-ZT1-Auth' = "$(Get-Content C:\ProgramData\ZeroTier\One\metricstoken.secret)"; } -Uri http://localhost:9993/metrics
-
-To configure a scrape job in Prometheus on the machine ZeroTier is running on, add this to your Prometheus `scrape_config`:
-
-    - job_name: zerotier-one
-      honor_labels: true
-      scrape_interval: 15s
-      metrics_path: /metrics
-      static_configs:
-      - targets:
-        - 127.0.0.1:9993
-        labels:
-          group: zerotier-one
-          node_id: $YOUR_10_CHARACTER_NODE_ID
-      authorization:
-        credentials: $YOUR_METRICS_TOKEN_SECRET
-
-If neither of these methods are desirable, it is probably possible to distribute metrics via [Prometheus Proxy](https://github.com/pambrose/prometheus-proxy) or some other tool.  Note: We have not tested this internally, but will probably work with the correct configuration.
-
-Metrics are also available on disk in ZeroTier's working directory:
-
-   // Linux
-   /var/lib/zerotier-one/metrics.prom
-
-   // macOS
-   /Library/Application\ Support/ZeroTier/One/metrics.prom
-
-   //Windows
-   C:\ProgramData\ZeroTier\One\metrics.prom
-

-If there are other metrics you'd like to see tracked, ask us in an Issue or send us a Pull Request!
-
-### HTTP / App server
-
-There is a static http file server suitable for hosting Single Page Apps at http://localhost:9993/app/<app-path>
-
-Use `zerotier-cli info -j` to find your zerotier-one service's homeDir
-
-``` sh
-cd $ZT_HOME
-sudo mkdir -p app/app1
-sudo mkdir -p app/appB
-echo '<html><meta charset=utf-8><title>appA</title><body><h1>hello world A' | sudo tee app/appA/index.html 
-echo '<html><meta charset=utf-8><title>app2</title><body><h1>hello world 2' | sudo tee app/app2/index.html 
-curl -sL http://localhost:9993/app/appA http://localhost:9993/app/app2 
-```
-
-Then visit [http://localhost:9993/app/app1/](http://localhost:9993/app/app1/) and [http://localhost:9993/app/appB/](http://localhost:9993/app/appB/)
-
-Requests to paths don't exist return the app root index.html, as is customary for SPAs. 
-If you want, you can write some javascript that talks to the service or controller [api](https://docs.zerotier.com/service/v1).
