Add a V2X data logger to Settings > Developer

Records every received V2X message (CAM, DENM, SPATEM, MAPEM, VAM) into one
SQLite file per run, with a timestamp, the phone's GNSS fix, the OBU's GNSS fix
where there is one (CiT One), and RSSI where the hardware reports it (ESP32-C5).
Works on both hardware paths: V2X_RX frames from the ESP32 link, and the raw
v2x/rx plus processed v2x-uca topics over MQTT. The UPER bytes are stored
untouched; CAM, DENM and SPATEM also get a few decoded columns.

A foreground service keeps it recording with the screen locked. Subscribes to
v2x/rx/mapem so MAPEM is received on the CiT One.

The current ESP32-C5 firmware forwards only BTP ports 2001, 2002 and 2004, so
MAPEM and VAM appear in an ESP32 log only once it accepts 2003 and 2018.

Checked on a Pixel 9 Pro against a simulated car and an RSU: 10 minutes with the
screen locked and forced deep Doze, no gaps, files pass integrity_check.

+      phone GNSS on every row, `obu_*` NULL, file integrity ok. MAPEM 0 as expected (firmware drops port 2003). Original steps: start a log, let the simulated car's CAMs arrive, stop. Pull the `.db` from
+      `files/v2x_logs/` and check `messages`: `msg_type='CAM'`, `source='esp32'`, `rssi_dbm` filled,

+      512-byte link limit, so most will still be counted as oversize drops. The app side already logs
+      any port. On the CiT One, MAPEM arrives via `v2x/rx/mapem` (subscribed now) or the processed

+ * Developer-tool logger: records every V2X message the phone receives, with a timestamp, the
+ * phone's GNSS fix, the OBU's GNSS fix where there is one, and RSSI where the hardware reports it,
+ * into one SQLite file per run (see [V2xLogWriter] for the schema).
+ *
+ * Works on both hardware paths and listens to whichever is selected:
+ *  - **ESP32-C5**: the V2X_RX frames from [Esp32Link], with the firmware's RSSI. No OBU position,
+ *    since that board has no GNSS.
+ *  - **CiT One**: the raw `v2x/rx` protobuf topics over MQTT, and the Use Case app's processed
+ *    `v2x-uca/output/json` topics as a second channel (the only source of MAPEM when the OBU does
+ *    not publish `v2x/rx/mapem`). The OBU's position comes from `v2x/rx/obu_gnss`. The API carries
+ *    no RSSI, so that column stays NULL.
+ *
+ * Every message is stored, including kinds the app cannot decode (MAPEM, VAM): the UPER bytes go
+ * in the file untouched, and where a decoder exists a few fields are decoded alongside for
+ * convenience. A message is never skipped because decoding failed.
+ *
+ * What it can hear is bounded by the hardware, not by this class: the current ESP32-C5 firmware
+ * forwards only BTP ports 2001, 2002 and 2004 (see `gn_unwrap.c`), so MAPEM and VAM appear in an
+ * ESP32 log only once the firmware accepts ports 2003 and 2018.
+ *
+ * A singleton, like the repositories it listens to. [com.hawhamburg.micr0bu.service.V2xLogService]
+ * keeps the process alive and the CPU awake while a log runs; this class does the work.

-# micrOBU ESP32-C5
-
-A standalone ITS-G5 (802.11p) VRU (Vulnerable Road User) ITS-S station on the
-ESP32-C5: firmware, the embedded [Vanetza](https://github.com/riebl/vanetza)
-C-ITS protocol stack (`external/vanetza-idf/`, see
-[PROVENANCE.md](external/vanetza-idf/PROVENANCE.md)), a phone-emulator
-example for the station-internal link, a localhost PKI reference chain, a
-Wireshark VAM dissector and the [V2X2MAP](https://github.com/711it/v2x2map)
-receiver bridge.
-
-A fresh clone can send a real, signed VAM (VRU Awareness Message) over the
-air in a handful of commands — see [Send a signed VAM](#4-send-a-signed-vam-in-a-few-commands)
-below. `station-link/python/demo-chain.vcr` is a disposable, **non-EU-registered**
-test credential chain generated specifically for this purpose (see
-[Security note on credentials](#security-note-on-credentials)); it carries no
-real-world trust and is safe to ship.
-
-## Quickstart
-
-### 1. Build & flash the ESP32-C5 firmware
-
-Requires [ESP-IDF](https://docs.espressif.com/projects/esp-idf/en/latest/esp32c5/get-started/) 6.0.2 with the `esp32c5` target.
-
-```powershell
-cd firmware
-idf.py set-target esp32c5
-idf.py build
-idf.py -p COM<PORT> flash monitor
-```
-
-### 2. Install the Wireshark VAM dissector
-
-Wireshark decodes IEEE 1609.2 / ETSI TS 103 097 secured packets only down to
-`unsecuredData` unless the PSID is registered in its dissector table. **PSID
-638** (VRU Awareness Service, ETSI TS 102 965) is not registered by default
-in Wireshark 4.x, so signed VAM traffic stops decoding at the security
-envelope without this plugin.
-
-```powershell
-# Windows
-Copy-Item tools\wireshark\psid-vru.lua "$env:APPDATA\Wireshark\plugins\"
-```
-```bash
-# Linux
-mkdir -p ~/.local/lib/wireshark/plugins && cp tools/wireshark/psid-vru.lua ~/.local/lib/wireshark/plugins/
-# macOS
-mkdir -p ~/.config/wireshark/plugins && cp tools/wireshark/psid-vru.lua ~/.config/wireshark/plugins/
-```
-
-Verify under **Help → About Wireshark → Plugins**, or use it directly with `tshark`:
-
-```bash
-tshark -X lua_script:tools/wireshark/psid-vru.lua -r capture.pcap
-```
-
-See [tools/wireshark/README.md](tools/wireshark/README.md) for details.
-
-### 3. Install Python dependencies
-
-```bash
-pip install -r station-link/python/requirements.txt
-pip install -r tools/v2x2map-0.3.0/bridge/requirements.txt
-```
-
-### 4. Send a signed VAM in a few commands
-
-With the firmware flashed (step 1) and the ESP32-C5 connected over USB
-Serial/JTAG, the phone emulator provisions the disposable demo credential
-chain and starts a small VRU basic service that assembles and transmits
-VAMs:
-
-```bash
-python station-link/python/phone_emulator.py \
-    --port COM<PORT> --bundle station-link/python/demo-chain.vcr \
-    --radio txrx --duration 30
-```
-
-That's it — the micrOBU signs every VAM with the demo AT ticket (VRU ITS-AID
-638, `psid 638 ssp 01`) and transmits it over ITS-G5. Capture it with a
-second ITS-G5-capable radio (or the [V2X2MAP bridge](#5-run-the-v2x2map-receiver-bridge-optional)
-below) and decode it with the [Wireshark dissector](#2-install-the-wireshark-vam-dissector)
-from step 2.
-
-To provision over BLE instead of USB, or to mirror packets to a `.pcap`
-without radiating, see the header of
-[`phone_emulator.py`](station-link/python/phone_emulator.py) for the
-`--ble`, `--radio off --divert --pcap` and full `--pki-*` (real online TS
-102 941 enrolment/authorization) variants, and
-[station-link/README.md](station-link/README.md) for the link protocol
-itself.
-
-### 5. Run the V2X2MAP receiver bridge (optional)
-
-A second ESP32-C5 flashed with the receiver firmware in
-[`tools/v2x2map-0.3.0/bridge/firmware/`](tools/v2x2map-0.3.0/bridge/firmware/)
-can feed a live web dashboard:
-
-```bash
-python tools/v2x2map-0.3.0/bridge/its_g5_bridge.py --port COM<PORT> --dashboard-port 8080 --open-browser
-```
-
-Open `http://localhost:8080` if it doesn't open automatically. This tool
-decodes VAMs for display but does **not** verify signatures (see
-[tools/v2x2map-0.3.0/README.md](tools/v2x2map-0.3.0/README.md)).

-## Security note on credentials
-
-`pki/uml-l0-rca/` documents the tooling for a **real, EU CCMS L0 ECTL-registered**
-root CA used elsewhere in the wider micrOBU project. Its private key material
-is intentionally **not** in this repository — `.gitignore` also backstops
-this (`*.vkey`, `*.ekey`, `private/`).
-
-`station-link/python/demo-chain.vcr` is unrelated: a separate, throwaway,
-**non-registered** root/AA/AT chain generated specifically for this repo's
-quickstart with `pki/uml-l0-rca/bin/windows/vidf_issue.exe`. Its
-`HashedId8` values do not match the registered root, it grants no real-world
-trust, and regenerating it is safe:
-
-```powershell
-$pool = "<some scratch directory>"
-$exe = "pki\uml-l0-rca\bin\windows\vidf_issue.exe"
-openssl ecparam -name prime256v1 -genkey -noout -out "$pool\demo_root_key.pem"
-& $exe root      --key "$pool\demo_root_key.pem" --name "Demo Root (NOT REGISTERED)" --id DEMO_RCA --out $pool --years 10
-& $exe authority --issuer "$pool\DEMO_RCA.oer" --issuer-key "$pool\demo_root_key.pem" --name "Demo AA" --id DEMO_AA --out $pool --years 5
-& $exe ticket    --issuer "$pool\DEMO_AA.oer"  --issuer-key "$pool\DEMO_AA.vkey" --id DEMO_AT --out $pool --hours 8760 --root "$pool\DEMO_RCA.oer"
-python external\vanetza-idf\ports\esp_idf\tools\credential_bundle.py build `
-    --pool $pool --root DEMO_RCA --aa DEMO_AA --at DEMO_AT --out station-link\python\demo-chain.vcr
-```
-
-`pki/uml-l0-rca/reference-generator/` cross-validates certificate generation
-against an independent Rust implementation ([`TheEnbyperor/c-its`](https://github.com/TheEnbyperor/c-its),
-pinned commit in [`reference-generator/README.md`](pki/uml-l0-rca/reference-generator/README.md)).
-Its vendored crates (`vendor/`) are excluded from this repository by
-`.gitignore` for size; regenerate with `cargo vendor` from that directory's
-`Cargo.lock`, or use `vidf_issue` directly as shown above — the vendor tree
-is only needed for that independent cross-check, not for ordinary use.

-                   GNU LESSER GENERAL PUBLIC LICENSE
-                       Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-
-  This version of the GNU Lesser General Public License incorporates
-the terms and conditions of version 3 of the GNU General Public
-License, supplemented by the additional permissions listed below.
-
-  0. Additional Definitions.
-
-  As used herein, "this License" refers to version 3 of the GNU Lesser
-General Public License, and the "GNU GPL" refers to version 3 of the GNU
-General Public License.
-
-  "The Library" refers to a covered work governed by this License,
-other than an Application or a Combined Work as defined below.
-
-  An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
-  A "Combined Work" is a work produced by combining or linking an
-Application with the Library.  The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
-  The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
-  The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
-  1. Exception to Section 3 of the GNU GPL.
-
-  You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
-  2. Conveying Modified Versions.
-
-  If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
-   a) under this License, provided that you make a good faith effort to
-   ensure that, in the event an Application does not supply the
-   function or data, the facility still operates, and performs
-   whatever part of its purpose remains meaningful, or
-
-   b) under the GNU GPL, with none of the additional permissions of
-   this License applicable to that copy.
-
-  3. Object Code Incorporating Material from Library Header Files.
-
-  The object code form of an Application may incorporate material from
-a header file that is part of the Library.  You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
-   a) Give prominent notice with each copy of the object code that the
-   Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the object code with a copy of the GNU GPL and this license
-   document.
-
-  4. Combined Works.
-
-  You may convey a Combined Work under terms of your choice that,
-taken together, effectively do not restrict modification of the
-portions of the Library contained in the Combined Work and reverse
-engineering for debugging such modifications, if you also do each of
-the following:
-
-   a) Give prominent notice with each copy of the Combined Work that
-   the Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the Combined Work with a copy of the GNU GPL and this license
-   document.
-
-   c) For a Combined Work that displays copyright notices during
-   execution, include the copyright notice for the Library among
-   these notices, as well as a reference directing the user to the
-   copies of the GNU GPL and this license document.
-
-   d) Do one of the following:
-
-       0) Convey the Minimal Corresponding Source under the terms of this
-       License, and the Corresponding Application Code in a form
-       suitable for, and under terms that permit, the user to
-       recombine or relink the Application with a modified version of
-       the Linked Version to produce a modified Combined Work, in the
-       manner specified by section 6 of the GNU GPL for conveying
-       Corresponding Source.
-
-       1) Use a suitable shared library mechanism for linking with the
-       Library.  A suitable mechanism is one that (a) uses at run time
-       a copy of the Library already present on the user's computer
-       system, and (b) will operate properly with a modified version
-       of the Library that is interface-compatible with the Linked
-       Version.
-
-   e) Provide Installation Information, but only if you would otherwise
-   be required to provide such information under section 6 of the
-   GNU GPL, and only to the extent that such information is
-   necessary to install and execute a modified version of the
-   Combined Work produced by recombining or relinking the
-   Application with a modified version of the Linked Version. (If
-   you use option 4d0, the Installation Information must accompany
-   the Minimal Corresponding Source and Corresponding Application
-   Code. If you use option 4d1, you must provide the Installation
-   Information in the manner specified by section 6 of the GNU GPL
-   for conveying Corresponding Source.)
-
-  5. Combined Libraries.
-
-  You may place library facilities that are a work based on the
-Library side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
-   a) Accompany the combined library with a copy of the same work based
-   on the Library, uncombined with any other library facilities,
-   conveyed under the terms of this License.
-
-   b) Give prominent notice with the combined library that part of it
-   is a work based on the Library, and explaining where to find the
-   accompanying uncombined form of the same work.
-
-  6. Revised Versions of the GNU Lesser General Public License.
-
-  The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
-  Each version is given a distinguishing version number. If the
-Library as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
-  If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

-                    GNU GENERAL PUBLIC LICENSE
-                       Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The GNU General Public License is a free, copyleft license for
-software and other kinds of works.
-
-  The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works.  By contrast,
-the GNU General Public License is intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users.  We, the Free Software Foundation, use the
-GNU General Public License for most of our software; it applies also to
-any other work released this way by its authors.  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
-  To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights.  Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received.  You must make sure that they, too, receive
-or can get the source code.  And you must show them these terms so they
-know their rights.
-
-  Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
-
-  For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software.  For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
-  Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so.  This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software.  The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable.  Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products.  If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
-  Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary.  To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy.  Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies.  Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License.  If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work
-for making modifications to it.  "Object code" means any non-source
-form of a work.
-
-  A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
-  The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form.  A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
-  The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities.  However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work.  For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met.  This License explicitly affirms your unlimited
-permission to run the unmodified Program.  The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work.  This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
-  You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force.  You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright.  Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
-  Conveying under any other circumstances is permitted solely under
-the conditions stated below.  Sublicensing is not allowed; section 10
-makes it unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
-  You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all.  For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
-  13. Use with the GNU Affero General Public License.
-
-  Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU Affero General Public License into a single
-combined work, and to convey the resulting work.  The terms of this
-License will continue to apply to the part which is the covered work,
-but the special requirements of the GNU Affero General Public License,
-section 13, concerning interaction through a network will apply to the
-combination as such.
-
-  14. Revised Versions of this License.
-
-  The Free Software Foundation may publish revised and/or new versions of
-the GNU General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-  Each version is given a distinguishing version number.  If the
-Program specifies that a certain numbered version of the GNU General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation.  If the Program does not specify a version number of the
-GNU General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
-  If the Program specifies that a proxy can decide which future
-versions of the GNU General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
-  Later license versions may give you additional or different
-permissions.  However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
-  15. Disclaimer of Warranty.
-
-  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
-  17. Interpretation of Sections 15 and 16.
-
-  If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software: you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation, either version 3 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program.  If not, see <http://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
-  If the program does terminal interaction, make it output a short
-notice like this when it starts in an interactive mode:
-
-    <program>  Copyright (C) <year>  <name of author>
-    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, your program's commands
-might be different; for a GUI interface, you would use an "about box".
-
-  You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU GPL, see
-<http://www.gnu.org/licenses/>.
-
-  The GNU General Public License does not permit incorporating your program
-into proprietary programs.  If your program is a subroutine library, you
-may consider it more useful to permit linking proprietary applications with
-the library.  If this is what you want to do, use the GNU Lesser General
-Public License instead of this License.  But first, please read
-<http://www.gnu.org/philosophy/why-not-lgpl.html>.

-EU CCMS CPOC L0 ECTL — RCA descriptive information
-===================================================
-
-Full Company Name / RCA Operator:
-Hochschule für Angewandte Wissenschaften Hamburg (HAW Hamburg)
-Urban Mobility Lab
-
-RCA Name:
-Urban Mobility Lab L0 Root CA
-
-RCA Distribution Centre URL:
-https://cits-dc.uml-hamburg.de
-
-Contact:
-uml-haw@proton.me
-
-CertificateID:
-0_Urban-Mobility-Lab-Root-CA_L0
-
-Certificate HashedID8:
-AFD566A8034ED5DB
-
-CertificateID / acronym explanation:
-- 0: CPA-ID reserved for the L0 environment.
-- Urban-Mobility-Lab-Root-CA: Root CA operated for the Urban Mobility Lab at HAW Hamburg.
-- L0: EU CCMS L0 research/test environment.
-
-Purpose of testing:
-The RCA is used for research, field testing and proof-of-concept activities of the
-Urban Mobility Lab in the context of the micrOBU project. micrOBU investigates the
-integration of vulnerable road users into C-ITS through development of a lightweight,
-compact and low-cost VRU ITS-S using an MCU + mobile-phone architecture.
-
-Contextual constraints / deviations:
-- This is a new RCA and the first L0 submission for this RCA. No existing L0 entry is
-  intended to be replaced or revoked.
-- The implementation, including the C-ITS protocol stack, signing functionality and
-  VRU Awareness Basic Service, is under active development. Full implementation
-  conformity is not claimed.
-- The declared RCA Distribution Centre is the intended permanent DC URL. At the time
-  of this submission, the cits-dc.uml-hamburg.de subdomain and the required /getctl
-  and /getcrl endpoints are still being commissioned and are not yet operational.
-- The RCA intentionally includes ITS-AID 638 (VRU Awareness basic service) with
-  bitmap SSP range 01/FF for L0 VAM/VBS research. ITS-AID 638 is a standardized ETSI
-  ITS-AID but is not contained in the current CPOC Protocol Release 3.3 Table 4 list;
-  its inclusion is therefore an intentional L0 profile deviation.
-- The RCA private key is generated and maintained locally as an encrypted PKCS#8
-  NIST P-256 key for this L0 research environment. This software-based key storage is
-  not claimed to satisfy production/L2 cryptographic-module requirements.
-
-Re-key / revocation / relationship to existing certificates:
-New RCA / first submission. No existing L0 RCA certificate is affected.
-
-Submission date:

-Reference notes
-===============

-Pinned upstream commit:
-e3bb3b82480d6df4237e2a8c35ea0dd7eade25b4
-
-The upstream commit's root generator:
-1. constructs a ToBeSignedCertificate;
-2. serializes it using rasn::oer::encode();
-3. calls PrivateKey::sign(hash_alg, &tbs_bytes, None);
-4. inserts the returned IEEE 1609.2 Signature into an ExplicitCertificate.
-
-The pinned c-its PrivateKey::sign() implementation for SHA-256 computes:
-
-    SHA256(
-        SHA256(tbs_bytes)
-        ||
-        SHA256(signer_info)
-    )
-
-For a self-signed root, signer_info is the empty byte string because the root
-generator passes None.
-
-This bundle uses that exact upstream code for the cryptographic operation.
-`rebuild_registered_rca.py` keeps the registered TBS/public key unchanged and uses
-the registered encrypted key. `create_new_root.py` creates a new encrypted key and
-replaces the template public key for a separate, unregistered candidate root. In
-both cases the scalar reaches Rust only through standard input.

-# UML L0 RCA generation tools
-
-Both tools use the Rust/c-its certificate path pinned to commit
-`e3bb3b82480d6df4237e2a8c35ea0dd7eade25b4`in https://github.com/TheEnbyperor/c-its. Requirements are Python 3.10+,
-`cryptography`, Git, Rust/Cargo, and internet access for the first build.
-
-## Rebuild the registered root
-
-```text
-python rebuild\_registered\_rca.py
-```
-
-Uses `private/UML\_L0\_RCA\_private\_encrypted.pem`. It succeeds only when the result is
-byte-for-byte identical to the registered `AFD566A8034ED5DB.oer`. Use this to prove
-how the registered certificate was made or to verify the registered key. It never
-creates a key and does not alter the registered files.
-
-## Create a separate new root
-
-```text
-python create\_new\_root.py
-```
-
-Creates a new P-256 key and candidate root certificate. It copies the registered
-root's reviewed TBS profile, including CertificateID, permissions, region and
-validity, but replaces the public key and signature. The result therefore has a
-different HashedId8 and is **not EU-registered**.
-
-Use this only for an isolated test root or a deliberate EU registration/re-key
-process. Before submission, review the inherited validity/profile and coordinate
-revocation or registration with the EU CCMS CPOC. Files appear under a directory
-named `CANDIDATE\_SUBMISSION\_NOT\_REGISTERED`; that name is a warning, not approval.
-
-In both workflows the private scalar is passed to the local Rust process through
-standard input and is never stored unencrypted by these tools.

-- 0: CPA-ID reserved for the L0 environment.
-- Urban-Mobility-Lab-Root-CA: Root CA operated for the Urban Mobility Lab at HAW Hamburg.
-- L0: EU CCMS L0 research/test environment.
-
-Purpose of testing:
-The RCA is used for research, field testing and proof-of-concept activities of the
-Urban Mobility Lab in the context of the micrOBU project. micrOBU investigates the
-integration of vulnerable road users into C-ITS through development of a lightweight,
-compact and low-cost VRU ITS-S using an MCU + mobile-phone architecture.
-
-Contextual constraints / deviations:
-- This is a candidate new RCA. It is not registered and must not be deployed until
-  the EU CCMS CPOC has completed the intended registration or re-key procedure.
-- The implementation, including the C-ITS protocol stack, signing functionality and
-  VRU Awareness Basic Service, is under active development. Full implementation
-  conformity is not claimed.
-- The declared RCA Distribution Centre is the intended permanent DC URL. At the time
-  of this submission, the cits-dc.uml-hamburg.de subdomain and the required /getctl
-  and /getcrl endpoints are still being commissioned and are not yet operational.
-- The RCA intentionally includes ITS-AID 638 (VRU Awareness basic service) with
-  bitmap SSP range 01/FF for L0 VAM/VBS research. ITS-AID 638 is a standardized ETSI
-  ITS-AID but is not contained in the current CPOC Protocol Release 3.3 Table 4 list;
-  its inclusion is therefore an intentional L0 profile deviation.
-- The RCA private key is generated and maintained locally as an encrypted PKCS#8
-  NIST P-256 key for this L0 research environment. This software-based key storage is
-  not claimed to satisfy production/L2 cryptographic-module requirements.

-# VRU ITS-S station-internal link (phone ⇄ micrOBU)
-
-Project interface **IF-PROJ-NF-BLE-001** made concrete, plus its DEC-VBS-004
-companions. One VRU ITS-S (ETSI EN 302 665 clause 4.5.1) is split over two
-physical units at the NF-SAP (DEC-VBS-003):
-
-| Unit | Hosts |
-|---|---|
-| Phone (app) | VRU basic service, VAM encode/decode, HMI, PoTi, credential manager (TS 102 941 client) |
-| micrOBU (ESP32-C5, this firmware) | BTP-B, GeoNetworking SHB/GBC, SN-SAP security entity (TS 103 097 signing, ticket pool, identifier change, SN-DECAP), ITS-G5 access |
-
-Everything that crosses the link is a standards-defined primitive
-(BTP-DATA.request/indication of TS 102 723-11 / TS 103 836-5-1 Annex A; the
-PoTi data set of EN 302 890-2 Tables 2 and 3; the SF-SAP identifier-change
-primitives of TS 102 723-9 Tables 10 to 21; the legacy/reference MF-SET parameter
-semantics of TS 103 175 Table 11) or
-one of three project-defined management messages (station configuration,
-credential provisioning with a `VCR1` bundle, status). No SN-, MN- or MI-SAP
-primitive crosses the link (ACT-015).
-
-The control/reference transport is the micrOBU's wired native USB Serial/JTAG
-port. Encrypted BLE GATT is an experimental alternative and shall not replace
-the wired architecture until ACT-021's controlled coexistence experiment shows
-that concurrent BLE does not disturb C5 PHY/CCA observation, ITS-G5 RF behavior,
-timing, reliability, or power measurements. The message layer below is transport
-independent. Nothing here is an ETSI on-air format or a conformance claim for
-the phone-to-micrOBU link.
-
-Implementations: firmware `firmware/main/link_protocol.*`,
-`ble_framing.*` and `ble_link.*` (C++); phone-side protocol module
-`microbuapp/station-link/` and Android central
-`microbuapp/app/src/main/java/com/hawhamburg/micr0bu/data/transport/BleStationLinkTransport.kt`
-(Kotlin); bench reference `station-link/python/microbu_link/`
-(Python, with serial and BLE adapters used by the phone emulator, TTCN SUT
-bridge and unit tests). Golden
-vectors and fragmentation are checked across the Python, C++ and Kotlin
-implementations.
-
-## Message layer (version 1)
-
-A reassembled message is at most **512 octets**. All integers
-are **little-endian** (the app's existing serial framing convention);
-ETSI-encoded payloads inside (UPER VAMs, COER certificates, GeoNetworking
-octets) are opaque and keep their own byte order.
-
-```
-octet 0     opcode
-octet 1     flags     bit 0: FRAGMENT_FIRST, bit 1: FRAGMENT_MORE (see Fragmentation); other bits 0
-octets 2-3  sequence  u16, see below
-octets 4-   body      opcode specific
-```
-
-Sequence: every request the phone sends carries its own counter; the micrOBU
-answers with a `RESULT` (or the typed reply named below) carrying the **same
-sequence**. Messages the micrOBU originates (indications, events, status) carry the
-micrOBU's own counter and are never answered, except `SF_IDCHANGE_EVENT` which the
-phone answers with `SF_IDCHANGE_EVENT_RESPONSE` echoing the event's sequence.

-### Bodies
-
-**RESULT (0x80)**: `u8 result`, `u8 detail_length`, `detail[]`. `result` is
-`vanetza_idf::Result` (0 accepted, 1 invalid_argument, 2 unsupported, 3
-wrong_entry_point, 4 security_unavailable, 5 resource_limit, 6 rejected, 7
-time_regression, 8 identity_change_pending) or a link code: 0x10
-unknown_opcode, 0x11 malformed, 0x12 not_configured (no STATION_CONFIGURE
-yet), 0x13 busy, 0x14 no_credentials. `detail` depends on the request:
-
-| Request | detail |
-|---|---|
-| STATION_CONFIGURE | `u8[8] gn_address` (as on the wire, TS 103 836-4-1 clause 6.3), `u8[8] identifier` (HashedId8 of the current authorization ticket, zeros when unsecured), `u8 credentials_loaded`, `u8 tickets` |
-| CREDENTIALS_PROVISION (last segment) | `u8 roots`, `u8 authorities`, `u8 tickets` accepted (ApplyReport) |
-| SF_IDCHANGE_SUBSCRIBE | `u64 subscription` |
-| SF_ID_LOCK | `u64 lock_handle` |
-| others | empty |
-
-**STATION_CONFIGURE (0x01)**: `u8 station_type` (TS 102 894-2 StationType, 2 =
-cyclist), `u8 security` (0 unsecured, 1 secured: itsGnSecurity), `u8
-address_configuration` (0 AUTO with the given MID, 1 ANONYMOUS: MID from the
-ticket digest, TS 103 836-4-1 clause 10.2.1.4), `u8[6] mid` (AUTO only),
-`u8 beaconing` (0/1, GN-MGMT beacons), `u16 channel_number` (ITS-G5 channel,
-180 = 5 900 MHz), `u8 transmit_power_dbm`, `u8 radio` (0 off, 1 receive only, 2
-transmit and receive — laboratory transmission stays an explicit choice), `u8
-default_traffic_class` (raw TC octet used when a request carries none), `u8
-default_lifetime` (raw GN Lifetime octet). Configuring (re)creates the stack on the micrOBU;
-a request before it is answered `not_configured`.
-
-**POTI_UPDATE (0x02)**: `u64 timestamp` (TimestampIts, TAI ms since
-2004-01-01; also synchronises the micrOBU's ITS clock), `i32 latitude`, `i32
-longitude` (1/10 µdeg, WGS84), `u16 semi_major`, `u16 semi_minor` (cm, 95 %
-horizontal confidence ellipse), `u16 orientation` (0.1°, semi-major axis from
-north), `u8 flags` (bit 0 altitude present, bit 1 speed present, bit 2 heading
-present, bit 3 position accuracy indicator), `i32 altitude` (cm), `u16 speed`
-(0.01 m/s), `u16 heading` (0.1°). The micrOBU answers only when it rejects the
-update (a `RESULT` with `time_regression` or `invalid_argument`); accepted
-updates are silent so a 10 Hz PoTi does not double the link traffic.
-
-**BTP_DATA_REQUEST (0x03)** (TS 103 300-3 Table 4 order):
-
-```
-u8  btp_type                    0 BTP-A, 1 BTP-B
-u16 destination_port
-u16 destination_port_info       (BTP-B) or source_port (BTP-A)
-u8  gn_packet_transport_type    1 SHB, 2 GBC (3 TSB, 4 GAC, 5 GUC are refused: unsupported)
-u8  gn_communication_profile    0 unspecified, 1 ITS-G5, 2 LTE-V2X
-u8  gn_security_profile         0 not given (station configuration), 1 unsecured, 2 secured
-u8  gn_traffic_class            raw TC octet (TS 103 836-4-1 clause 9.7.5); 0xFF = station default

-u8  permissions[]
-u8  context_length              SN-ENCAP context_information (vam_cluster = 01) …
-u8  context[]

-            u16 distance_a, u16 distance_b (m), u16 angle (°)
-u16 length                      of the FL-SDU (the VAM)
-u8  fl_sdu[length]
-```
-
-The micrOBU hands this to `NF_SAP::BTP_DATA_request_submit`. `RESULT.result` is
-the library's acceptance (accepted = submitted for protocol processing, not
-proof of transmission). A secured request whose signing the entity refuses
-(no valid ticket, identifier change pending) is visible in `STATUS` counters.
-
-**BTP_DATA_INDICATION (0x81)**: `u8 btp_type`, `u16 destination_port`, `u16
-destination_port_info` (or source_port), `u8 gn_packet_transport_type`, `u8
-gn_traffic_class`, `u8 gn_remaining_packet_lifetime` (raw, 0xFF absent), `u8
-gn_remaining_hop_limit` (0xFF absent), `u8[8] source_gn_address`, `u32
-source_timestamp` (TST ms), `i32 source_latitude`, `i32 source_longitude`,
-`u8 security_report` (0 unsecured, 1 + `VerificationReport` ordinal: 1
-Success, 2 False_Signature, …), `u32 its_aid` (0 when absent), `u8
-permissions_length`, `permissions[]`, `u8 certificate_present`, `u8[8]
-certificate_id`, `u8 area_present`, [`u8 shape`, `i32 lat`, `i32 lon`, `u16
-a`, `u16 b`, `u16 angle`], `u16 length`, `received_fl_sdu[]`.
-
-**CREDENTIALS_PROVISION (0x04)**: `u16 total_length`, `u16 offset`, `u8
-segment_length`, `segment[]`. The segments of one bundle arrive in order;
-`offset + segment_length == total_length` ends it. The micrOBU decodes the bundle,
-applies it through the security entity's checks (`security::apply`), saves it
-in the NVS credential store when every item was accepted, and rebuilds the
-station with it. Keys travel in the clear: the transport must be a trusted
-one (a paired, encrypted BLE link; a USB cable on the bench).
-
-**SF_IDCHANGE_SUBSCRIBE (0x06)**: `u8 subscriber_data_length`,
-`subscriber_data[]`. **SF_IDCHANGE_UNSUBSCRIBE (0x07)**: `u64 subscription`.
-**SF_IDCHANGE_EVENT (0x82)**: `u64 subscription`, `u8 command` (0 PREPARE, 1
-COMMIT, 2 ABORT, 3 DEREG), `u8[8] id` (HashedId8 of the next ticket), `u8
-subscriber_data_length`, `subscriber_data[]`. **SF_IDCHANGE_EVENT_RESPONSE
-(0x08)**: `u64 subscription`, `u8 return_code` — sent for PREPARE and COMMIT
-with the event's sequence; the service's response timeout (500 ms) applies
-across the link. **SF_IDCHANGE_TRIGGER (0x09)**: empty. **SF_ID_LOCK (0x0A)**:
-`u8 duration_seconds`. **SF_ID_UNLOCK (0x0B)**: `u64 lock_handle`.
-
-**MF_SET_REQUEST (0x83)**: `u32 fac_id`, `u8 command_ref`, `u8 count`, then
-`count` × (`u8 f_param_no`, `u32 value`) with TS 103 175 Table 13 numbers (0
-CHANNEL_NUMBER, 1 AVAILABLE_RESOURCE). The micrOBU sends it only for measurements
-its access layer actually made; it never invents a channel load (ACT-021).
-
-**STATUS (0x84)**: `u32 uptime_ms`, `u8 configured`, `u8[8] gn_address`,
-`u8[8] identifier`, `u8 change_pending`, `u8 tickets`, `u32 signed_messages`,
-`u32 refused_no_ticket`, `u32 refused_change_pending`, `u32
-refused_permission`, `u32 sign_failed`, `u32 verified`, `u32 rejected`
-(SN-DECAP rejections of every kind), `u32 requests_accepted`, `u32
-requests_refused`, `u32 indications`, `u32 radio_submitted`, `u32
-radio_failed`, `u32 radio_received`, `u32 radio_dropped`, `u32
-link_rx_frames`, `u32 link_crc_errors`, `u32 link_malformed`, `u32
-poti_updates`, `u64 its_time` (current micrOBU ITS clock, ms; 0 before the first
-POTI_UPDATE). The micrOBU sends it every second unsolicited and on STATUS_REQUEST.
-
-### Fragmentation
-
-A message longer than the transport's unit (ATT_MTU − 3 for a notification; a
-GATT client's long write handles 512 B values itself) is sent as fragments,
-each with the full 4-octet header and the same sequence: the first with
-FRAGMENT_FIRST, every one but the last with FRAGMENT_MORE. The receiver
-concatenates the bodies. The serial transport carries whole messages and never
-sets these bits.
-
-## Transports
-
-### Serial (bench and conformance tests)
-
-Native USB Serial/JTAG of the micrOBU's ESP32-C5 (VID 303A, PID 1001), the app's Phase 03
-framing (`obu-firmware/main/serial_link.h`, `SerialFrame.kt`):
-
-```
-[0xAA][0x55][type:1][length:2 LE][payload][crc16:2 LE]
-```
-
-CRC-16/CCITT-FALSE (poly 0x1021, init 0xFFFF) over type + length + payload.
-Frame types of this firmware:
-
-| Type | Payload |
-|---|---|
-| 0x10 | one link message (above), ≤ 512 octets |
-| 0x11 | test channel request (PC → micrOBU) / reply (micrOBU → PC), ≤ 1 536 octets, only in a test build |
-| 0x7F | UTF-8 log line from the firmware (ESP_LOG output; the console stays free of binary frames) |
-
-The maximum frame payload is 1 536 octets (a mirrored GNPDU can exceed 512).
-Frames the phone does not know are ignored; text outside frames (ROM boot
-messages) is skipped by the sync/CRC search.
-
-### BLE GATT (production transport)
-
-The transport uses the Nordic UART Service UUID layout so standard BLE tools
-can inspect it. It is a byte transport for the project message layer, not the
-Nordic UART wire protocol:
-
-| GATT object | UUID | Properties | Direction |
-|---|---|---|---|
-| Primary service | `6e400001-b5a3-f393-e0a9-e50e24dcca9e` | primary | — |
-| RX/request | `6e400002-b5a3-f393-e0a9-e50e24dcca9e` | write, write without response | phone → micrOBU |
-| TX/notification | `6e400003-b5a3-f393-e0a9-e50e24dcca9e` | notify | micrOBU → phone |
-
-The peripheral advertises the service and the name `micrOBU-XXXX`, where the
-suffix is derived from its Bluetooth MAC. GATT access requires an authenticated,
-encrypted connection. The ESP32 uses LE Secure Connections, bonding and a
-fresh six-digit passkey printed to the USB log (DisplayOnly); NimBLE persists
-the bond in NVS. Android presents the normal system pairing UI and retains the
-bond. This protects the credential bundle in transit; it is not application-
-layer encryption.
-
-Android requests an ATT MTU of 517; the ESP32 preference is 512. The Android
-writer uses `ATT_MTU - 3`, capped at 512, after negotiation (509 octets with
-the current ESP32 configuration) and falls back to 20 octets.
-The ESP32 notification path deliberately emits values of at most 20 octets so
-it also works at the mandatory default MTU. Every value uses the fragmentation
-flags above and repeats the link header; a complete message is limited to 512
-octets. Writes are acknowledged and serialized. Notifications are enabled
-before the Android adapter reports `READY`. The USB test channel is never
-exposed over BLE.
-
-## Test channel (test firmware only, USB only)
-
-`CONFIG_MICROBU_TEST_CHANNEL` compiles a software lower tester and the
-diagnostic hooks the ETSI campaigns need, behind frame type 0x11. It is not
-part of the phone interface and never exists on BLE. Requests: `u8 command`,
-reply `u8 result`, `u8 record_count`, records `[kind u8][length u16 LE][bytes]`:
-
-| Command | Body | Effect |
-|---|---|---|
-| 0x01 MIRROR | `u8 mode` (0 off, 1 mirror, 2 divert) | every AL_DATA.request the stack makes is copied (mirror) or kept from the radio (divert) and queued as kind-1 records |
-| 0x02 INJECT | `u8[6] source`, `u8[6] destination`, `gnpdu[]` | AL_DATA.indication from the lower tester into the stack |
-| 0x03 GN_REQUEST | `u8 traffic_class`, `payload[]` | GN-DATA.request SHB with next header "Any" (the Security ATS GN-MGMT/GENMSG cases; N-SAP, not a phone primitive) |
-| 0x04 DRAIN | – | returns the queued records: kind 1 AL_DATA.request (the GNPDU as submitted), kind 2 BTP-DATA.indication (`[type][dest port][port info][SDU]`), kind 3 GN-DATA.indication payload |
-| 0x05 RESET | – | drops the queue and the mirror mode |
-
-The queue is bounded (32 records, 8 KiB); an overflow is reported as
-`resource_limit` on the next DRAIN and the records lost are counted.
-
-## Phone emulator, SUT bridge and campaigns (PC side)
-
-`python/microbu_link/` is the phone side of the message layer (codec, serial
-transport, request/reply client, the small VBS of `vbs.py`), shared by:
-
-- `python/phone_emulator.py` — the phone half of the VRU ITS-S on a PC:
-  configures the micrOBU, provisions a `VCR1` bundle, feeds PoTi (static or a
-  bicycle on a circle), assembles VAMs with asn1tools from the ETSI ASN.1 of the
-  submodule and hands them over with the PCI of TS 103 300-3 Table 4 under the
-  generation rules of clause 6.4, subscribes to the identifier-change events
-  (stop on PREPARE, new StationId after COMMIT), prints the indications, status
-  and log lines; `--divert --pcap` records what the micrOBU signs for an
-  independent verifier. Its default synthetic trajectory is a 20 m-radius circle
-  at 2 m/s centred at 53.5652470 N, 10.0082390 E over the Außenalster's open
-  water; `--lat`, `--lon`, `--radius` and `--speed` override it. Radio emission
-  remains opt-in through `--radio txrx`. The center is not itself a transmitted
-  position: generated positions lie on the circle perimeter. The firmware's
-  standalone BOOT-button VAM is a separate fixed payload and does not use these
-  phone-emulator coordinates.
-- `python/sut_bridge.py` — the SUT process of the vanetza-idf ETSI adapters
-  (hex-line protocol of `hil_sut.hpp`) with the micrOBU behind the phone
-  interfaces: BTP-DATA.request, PoTi and credentials over the link, the software
-  lower tester over the USB test channel, CAM/DENM stimuli assembled on the PC.
-  `--listen host:port` serves the protocol over TCP; `python/sut_tcp_relay.py`
-  inside WSL is the SUT executable that forwards it (WSL interop drops piped
-  stdin of Windows executables).
-
-```powershell
-# Windows: the micrOBU on COM11, the campaign pool packed as a bundle
-python sut_bridge.py --port COM11 --bundle pool.vcr --listen 0.0.0.0:7788
-```
-
-`LinkClient` is transport-independent. `SerialTransport` and `BleTransport`
-implement the same `TransportAdapter.write(frame_type, payload)` / `close()`
-boundary and feed the same receive callback; configure, PoTi, credential,
-BTP-DATA, status and event code is therefore identical. Select only the adapter
-at the command line:
-
-```powershell
-cd implementation\station-link\python
-python -m pip install -r requirements.txt
-
-# Safe first BLE run: hand VAMs to an unsecured station, with ITS-G5 RF off.
-python phone_emulator.py --ble --unsecured --radio off --period 1000 --duration 10 --verbose `
-  --report ble-vam-session.json
-
-# Select a particular advertisement when several micrOBUs are present.
-python phone_emulator.py --ble micrOBU-1234 --unsecured --radio off --duration 10
-```
-
-For the signed run, replace `--unsecured` with `--bundle <path-to-chain.vcr>`
-(or use credentials already retained in the micrOBU NVS). Change `--radio off`
-to `--radio txrx` only for the intended laboratory RF test. The USB test
-channel has no BLE equivalent, so `--mirror`, `--divert` and `--pcap` are
-rejected with `--ble`; all station-link/VAM behavior above that adapter is the
-same.
-
-Instead of an offline `--bundle`, `--pki-url` makes the emulator obtain an
-enrolment credential and authorization ticket from `tools/local_pki.py`, build
-the same `VCR1` bundle, and provision it before starting the VBS. Supply
-`--pki-root`, `--pki-ea`, `--pki-aa`, `--pki-canonical-key`, `--pki-its-id`,
-`--pki-issue-tool`, `--pki-client-tool`, and `--pki-bundle-tool` together; use
-`--pki-hours` to override the 24-hour AT validity. The message flow and retained
-host-side proof are documented in `docs/idf/evidence/enrolment-authorization-01`
-and the EA/AA section of `docs/idf/test-campaigns.md` in vanetza-idf.
-`local_pki.py` is a separate localhost HTTP process, normally bound to
-`127.0.0.1`; it is not imported into or hosted by the emulator. Consequently,
-the lab authority can later be replaced by a hosted PKI without changing the
-phone flow: set `--pki-url` to the hosted access point and keep the same S3/S4
-HTTP interface.
-
-## End-to-end hardware workflow: Online PKI, Transmission & Reception
-
-This workflow runs the full online TS 102 941 enrolment/authorization and 5.9 GHz ITS-G5 over-the-air transmission between two ESP32-C5 boards:
-- **COM4 (TX)**: micrOBU running firmware microbu_firmware.bin
-- **COM5 (RX)**: independent receiver running 2x2map-0.3.0 bridge firmware

-Retained runs of 2026-09-14: `experiments/raw/microbu-link-20260914/`
-(manifests in `experiments/manifests/test-runs/microbu-link-20260914-*.yaml`).
-
-## BLE verification (2026-09-16)
-
-The retained host verification is described by
-`experiments/manifests/test-runs/microbu-link-20260916-ble-host-01.yaml`:
-
-- Python/C++ protocol and framing suite: 8 tests passed, including the common
-  serial/BLE adapter contract and a 512-octet
-  message split into 32 default-MTU values, reassembly, malformed interleaving
-  rejection and recovery.
-- Kotlin/JVM station-link suite: 4 tests passed against the Python/C++ golden
-  bytes, including fragmentation, recovery and credential segmentation.
-- Android `:app:compileDebugKotlin`: passed with the BLE central and manifest
-  permissions included.
-- ESP-IDF 6.0.2 ESP32-C5 build: passed with NimBLE and the encrypted GATT
-  peripheral; the binary is `0x1d8780` bytes and leaves 38% of the app partition.
-
-No ESP32 serial device or Pixel 9 was attached to this laptop during this run,
-so pairing, notification exchange, the <= 2 s reconnection requirement and the
-connection-loss-rate requirement were not measured. `TEST-AC-SYS-MICROBU-013` and
-`TEST-AC-SYS-MICROBU-014` intentionally remain planned hardware tests.

-The adapters (ports/esp_idf/tests/etsi_*_adapter.cpp) drive a SUT through the hex-line

-half of the VRU ITS-S would: BTP-DATA.request, PoTi time/position and credential
-provisioning go over the station-internal link; the software lower tester (observing
-AL_DATA.request, injecting AL_DATA.indication) and the GN-DATA.request of the Security
-ATS use the USB test channel of the test firmware. The CAM/DENM carrier stimuli of the
-Security ATS are assembled here with asn1tools, as a phone would assemble them.

-Commands (first octet, as in hil_sut.hpp): 0 reset; 1 BTP-DATA.request; 2 AL_DATA.indication;
-3 GN-DATA.request SHB; 4 position; 5 advance the ITS clock (reports transmissions); 6 carrier
-CAM/DENM now; 7 periodic carrier; 8 carrier with the next clock advance; 9 credential bundle.
-Reply: [result][count]{[kind][u16 BE length][bytes]}, kind 1 AL_DATA.request, 2 BTP-DATA.indication,

-# V2X2MAP bridge (vendored, bridge-only)
-
-This is a pruned copy of the `bridge/` component of
-[V2X2MAP](https://github.com/711it/v2x2map) 0.3.0, a receiver/live-map tool
-for ITS-G5 V2X traffic. V2X2MAP is itself a fork of
-[opentrafficmap/its-g5-receiver-firmware](https://codeberg.org/opentrafficmap/its-g5-receiver-firmware)
-extended with BLE streaming, an Android app and a Windows installer — see
-[the upstream project](https://github.com/711it/v2x2map) for the full
-firmware/Android/iOS sources and license (MIT, `LICENSE` in this directory).
-
-## Why it is here
-
-`bridge/` is the host-side Python tool (serial/BLE ingestion, dashboard,
-recording, VAM/CAM decoding) used for prototyping and to sanity-check VAM
-decoding independently of this project's own `external/vanetza-idf`
-stack. It has been locally modified to decode VAMs (`bridge/vam.py`,
-`bridge/test_vam.py`, `bridge/asn1/`) and, since 2026-09-14, to look inside
-signed GeoNetworking packets (`bridge/secured.py`: a bounded COER walk of the
-TS 103 097 `Ieee1609Dot2Data` that returns the unsecured payload, PSID,
-generation time and signer; the signature is **not** verified, the dashboard
-says "signed … not verified").
-
-The Android app and the receiver firmware from the original project are not
-carried into this repository; this project uses its own ESP32-C5 firmware
-(`firmware/`, `external/vanetza-idf/`) instead.
-`bridge/firmware/*.bin` is a small set of prebuilt images kept only so the
-bridge's recording/decode workflow can be exercised against a receiver board
-without a separate firmware build.
-
-## Use
-
-See `bridge/its_g5_bridge.py` and `bridge/dashboard_server.py` for the
-serial/BLE bridge and local dashboard; `bridge/vam.py` for the VAM decode
-path. `bridge/requirements.txt` lists its Python dependencies (separate from
-this project's own `station-link/python/requirements.txt`).

- * At least one of the fields below shall be present if the container is present in the VAM: 
- *
- * @field pathHistory: represents the VRU's recent movement over some past time and/or distance. 
- *        It consists of a list of path points. 
- * @field pathPrediction: provides the set of predicted locations of the ITS-S, confidence values 
- *        and the corresponding future time instants. 
- * @field safeDistance: provides indication of safe distance between an ego-VRU and up to 8 other ITS-S 
- *        or entity on the road to indicate whether the ego-VRU is at a safe distance (that is less likely to 
- *        physically collide) from another ITS-S or entity on the road. 
- * @field trajectoryInterceptionIndication: provides the indication for possible trajectory interception 
- *        with up to 8 VRUs or other objects on the road.. 
- * @field accelerationChangeIndication: provides an acceleration change indication of the VRU. 
- *        When present this DF indicates an anticipated change in the VRU speed for period of actionDeltaTime.
- * @field headingChangeIndication: provides additional data elements associated to heading change indicators 
- *        such as a change of travel direction (left or right). 
- *        The direction change action is performed for a period of actionDeltaTime. 
- * @field stabilityChangeIndication: provides an estimation of the VRU stability.
