 ## travis build scripts
 
+Status: legacy documentation. The current Agrarian 2.0 modernization work is
+validated with local build helpers and smoke tests, not Travis CI.
+
 The `.travis` directory contains scripts for each build step in each build stage.
 Currently the travis build defines two stages `lint` and `test`. Each stage has
 it's own [lifecycle](https://docs.travis-ci.com/user/customizing-the-build/#the-build-lifecycle).
 Every script in here is named and numbered according to which stage and lifecycle
 step it belongs to.

+
+For the Ubuntu desktop wallet:
+
+    JOBS=1 ./contrib/build-linux-wallet.sh
+
+For a manual build, build depends first and configure against its config.site:
+
+    make -C depends HOST=x86_64-pc-linux-gnu NO_QT=0
+    ./autogen.sh
+    CONFIG_SITE=$PWD/depends/x86_64-pc-linux-gnu/share/config.site ./configure
     make
 
-Always verify the signatures and checksums.
+The current native Qt wallet depends baseline includes Qt 6.8.3, OpenSSL 3.5.6,
+Boost 1.91.0, Expat 2.8.0, FreeType 2.14.3, Berkeley DB 4.8.30, libevent, and
+GMP. Protobuf/BIP70 payment requests were removed. Prefer the helper scripts in
+`contrib/` for repeatable fresh-host builds.
+
+Always verify source checksums and release signatures when building a release.

+# Agrarian 2.0 Development Roadmap
+
+This file tracks the 2.0 line before it becomes the main Agrarian codebase.
+
+## Current Release Goal
+
+Agrarian 2.0 should be the modern, buildable baseline for the coin:
+
+- Ubuntu daemon builds
+- Ubuntu Qt wallet builds
+- Windows daemon cross-builds
+- Windows Qt wallet cross-builds
+- ARM64 daemon builds for server nodes
+- clean enough docs and scripts for repeatable fresh-server builds
+- stable network behavior with existing Agrarian nodes
+
+## Validation Before Promoting 2.0 To Main
+
+- Linux daemon: validated on Ubuntu with `contrib/build-linux.sh`.
+- Linux Qt wallet: validated on Ubuntu with `contrib/build-linux-wallet.sh`.
+- Daemon smoke test: validated with `contrib/smoke-test-daemon.sh`.
+- Wallet smoke test: validated with `contrib/smoke-test-wallet.sh`.
+- Qt smoke test: validated with `contrib/smoke-test-qt.sh`.
+- Windows daemon: validated with the build menu on x86_64 Ubuntu.
+- Windows Qt wallet: validated with the build menu on x86_64 Ubuntu.
+- Linux ARM64 daemon: validated with the build menu cross-build from x86_64 Ubuntu.
+- Linux ARM64 Qt wallet: native ARM64 build only for now; x86_64 menu guard validated.
+
+## Build Script Targets
+
+The build menu is the preferred entry point:
+
+```bash
+./contrib/agrarian-build-menu.sh
+```
+
+Supported targets:
+
+- Linux daemon and CLI tools
+- Linux Qt GUI wallet
+- Windows daemon and CLI tools
+- Windows Qt GUI wallet
+- Linux ARM64 daemon and CLI tools
+- Linux ARM64 Qt GUI wallet, native ARM64 host only
+
+The script should:
+
+- clone or fast-forward the selected branch
+- install Ubuntu packages needed for the selected target
+- refuse unsafe root execution unless explicitly overridden for controlled CI/root environments
+- stop a running user daemon gracefully before replacing binaries
+- refuse to force-close the GUI wallet
+- restore a daemon it stopped when the build completes
+
+## Dependency Policy
+
+Already modernized in the 2.0 line:
+
+- OpenSSL LTS path
+- Boost current modern path
+- Qt 6.8 LTS path
+- expat
+- freetype
+- zlib
+- libevent
+- zeromq
+- qrencode
+- miniupnpc
+- GMP
+- protobuf
+
+Berkeley DB stays on 4.8.30 for the 2.0 release to preserve wallet compatibility.
+Do not jump to BDB 18.x in 2.0. A future wallet database migration should be a
+planned project, likely toward SQLite, with explicit wallet backup and migration
+tooling.
+
+## Known Follow-Up Work
+
+- Re-run Windows daemon and Windows Qt wallet validation after every dependency change.
+- Keep ARM64 Qt wallet as native-only until a reliable cross-Qt path is designed.
+- Reduce remaining compiler warning noise where it affects correctness.
+- Replace deprecated `std::random_shuffle` usage.
+- Audit old Boost and LevelDB warning areas without changing consensus behavior casually.
+- Build a formal release packaging process for Linux and Windows artifacts.
+- Add repeatable clean-machine CI once the local build menu is stable.
+- Plan the SQLite wallet migration as a post-2.0 milestone.
+- Continue wallet UX modernization after the 2.0 build baseline is promoted.

+Interactive Build Menu
+======================
+
+`contrib/agrarian-build-menu.sh` provides an interactive Ubuntu build workflow
+for common Agrarian targets:
+
+- Linux daemon and CLI tools
+- Linux Qt GUI wallet
+- Windows daemon and CLI tools
+- Windows Qt GUI wallet
+- Linux ARM64 daemon and CLI tools
+- Linux ARM64 Qt GUI wallet
+
+The script clones the Agrarian repository if the selected checkout directory
+does not exist. If the checkout already exists, it fetches, checks out the
+configured branch, and performs a fast-forward pull.
+
+Only bootstrap packages needed to update the checkout are installed before the
+pull. Target-specific packages are installed after the checkout is current, so
+fresh dependency fixes on the selected branch are applied before the build.
+After updating the checkout, the launcher restarts itself from the checked-out
+copy so the current branch version of the menu is used for package installation
+and build steps. The selected target, checkout directory, and job count are
+preserved across that restart.
+
+Quick Start
+-----------
+
+From an existing checkout:
+
+    ./contrib/agrarian-build-menu.sh
+
+Do not run the script with `sudo`. It runs checkout, compilation, daemon config,
+and the user systemd service as the current local user. It asks for sudo only
+when it needs to install Ubuntu packages or set MinGW compiler alternatives.
+
+From a fresh Ubuntu host:
+
+    sudo apt-get update
+    sudo apt-get install -y git ca-certificates
+    git clone --branch 2.0 https://github.com/pacificao/agrarian.git agrarian
+    cd agrarian
+    ./contrib/agrarian-build-menu.sh
+
+On minimal VPS images, apt sources may be incomplete. The script checks for
+missing Ubuntu `-updates` and `-security` suites before installing build
+packages. If they are missing, it asks before adding a standard
+`/etc/apt/sources.list.d/agrarian-ubuntu.sources` file for the host
+architecture.
+
+The Linux daemon option uses the deterministic native `depends/` build with Qt
+disabled, so Berkeley DB and other core libraries are built inside the checkout
+instead of being required as Ubuntu system development packages.
+
+The Linux Qt wallet option also installs Ubuntu desktop development headers
+needed by Qt's xcb platform plugin, including fontconfig, freetype, xcb, and
+xkbcommon packages. Expat 2.8.0 and FreeType 2.14.3 are built through
+`depends/` for the Linux Qt/font stack. Protobuf is not required because
+obsolete BIP70 payment request support was removed. The helper also clears
+stale Qt work directories before rebuilding, because failed CMake
+feature checks can otherwise be cached between attempts.
+
+The Linux ARM64 daemon option cross-compiles the daemon and CLI tools from an
+x86_64 Ubuntu host when the `g++-aarch64-linux-gnu` and
+`binutils-aarch64-linux-gnu` packages are available. On an ARM64 Ubuntu host it
+uses the normal native Linux daemon path.
+
+The Linux ARM64 Qt wallet option is native-only. Run it on an ARM64 Ubuntu
+desktop/server with the Qt/XCB development packages installed. The current Qt 6
+Linux wallet build depends on target-system XCB/font pkg-config metadata, so the
+menu does not advertise a fragile x86_64-to-ARM64 Qt GUI cross-build path.
+
+Defaults
+--------
+
+The script can be configured with environment variables:
+
+    REPO_URL=https://github.com/pacificao/agrarian.git
+    BRANCH=<current checkout branch, or main when run standalone>
+    WORKDIR=$HOME/agrarian
+    JOBS=<detected CPU count>
+
+Example:
+
+    JOBS=8 WORKDIR=$HOME/src/agrarian ./contrib/agrarian-build-menu.sh
+
+To test the 2.0 branch from a standalone downloaded copy of the script:
+
+    BRANCH=2.0 ./agrarian-build-menu.sh
+
+Linux Daemon Autostart
+----------------------
+
+After a Linux daemon-capable build, the script asks whether to install and start
+`agrariand` for the current user. If accepted, it creates:
+
+- `$HOME/.local/bin/agrariand`
+- `$HOME/.local/bin/agrarian-cli`
+- `$HOME/.agrarian/agrarian.conf`
+- `$HOME/.config/systemd/user/agrariand.service`
+
+It then enables and starts the user service with:
+
+    systemctl --user enable --now agrariand.service
+
+Windows Build Output
+--------------------
+
+For Windows targets, the script prints the `.exe` artifact paths when the build
+finishes. Copy the generated files from `src/` and `src/qt/` to the Windows
+machine and run either `agrariand.exe` or `agrarian-qt.exe`.
+
+ARM64 Build Output
+------------------
+
+For ARM64 daemon targets, the script prints the generated Linux binaries in
+`src/`. Copy them to the ARM64 machine if the build was cross-compiled. For the
+ARM64 Qt wallet target, the build should be run directly on the ARM64 machine
+and the wallet binary is `src/qt/agrarian-qt`.

+The daemon script confirms RPC and wallet calls work, mines one block, checks
+the block count, and stops the daemon. The wallet script checks address
+creation, mining, send/confirm, backup, and encryption shutdown. The Qt script
+starts `agrarian-qt` under Xvfb and confirms the GUI reaches `Done loading`
+without Qt6 TLS, signal, or stylesheet compatibility warnings.
 
 OpenSSL 3
 ---------
 
-Ubuntu 24.04 ships OpenSSL 3. Agrarian no longer rejects this only because
-`RAND_egd` is unavailable. Some deprecated OpenSSL SHA calls still warn during
-compilation; those warnings are expected until the hashing helper code is
-modernized.
+The deterministic depends build currently uses OpenSSL 3.5.6.
+
+Expat and FreeType
+------------------
+
+The native Ubuntu Qt wallet path uses Expat 2.8.0 through fontconfig and
+FreeType 2.14.3 for Qt 6 static font support. Keep those in the deterministic
+depends graph; do not satisfy them with ad hoc system-library fallbacks.

+Agrarian 2.0 Modernization Status
+=================================
+
+This branch is the modernization line for Agrarian. The goal is to preserve
+network behavior while making the codebase build repeatably on current systems.
+
+Verified Build Baseline
+-----------------------
+
+Use Ubuntu 24.04 as the primary build host.
+
+The current deterministic `depends/` baseline is:
+
+- Qt 6.8.3 LTS
+- OpenSSL 3.5.6 LTS
+- Boost 1.91.0
+- Expat 2.8.0 for the Linux Qt/font stack
+- FreeType 2.14.3 for Qt 6 static font support
+- Berkeley DB 4.8.30 for portable legacy wallet compatibility
+- qrencode 4.1.1 for Qt wallet QR code support
+- libevent 2.1.12-stable
+- GMP 6.3.0
+- MiniUPnPc 2.3.3 when UPnP support is enabled
+- ZeroMQ 4.3.5 when enabled
+
+Obsolete BIP70 payment request support was removed to eliminate the protobuf
+and `protoc` dependency from the wallet build. Standard `agrarian:` URI payment
+links are still supported.
+
+Berkeley DB 4.8.30 is intentionally retained for legacy `wallet.dat`
+compatibility. Future wallet-storage modernization should add a dedicated SQLite
+backend and migration flow instead of changing the BDB version in-place.
+
+The currently verified binaries are:
+
+- Ubuntu daemon and command-line tools
+- Ubuntu Qt desktop wallet
+- Windows x86_64 Qt desktop wallet and command-line tools cross-compiled from
+  Ubuntu
+
+Recommended Commands
+--------------------
+
+Native Ubuntu daemon:
+
+    JOBS=1 ./contrib/build-linux.sh
+
+Native Ubuntu desktop wallet:
+
+    JOBS=1 ./contrib/build-linux-wallet.sh
+
+Windows x86_64 desktop wallet:
+
+    JOBS=1 ./contrib/build-win64-wallet.sh
+
+Use higher `JOBS` values only on hosts with enough memory. On an 8-core, 16 GB
+host, `JOBS=8` is reasonable.
+
+Verification
+------------
+
+After a native Ubuntu build, run:
+
+    ./contrib/smoke-test-daemon.sh
+    ./contrib/smoke-test-wallet.sh
+    ./contrib/smoke-test-qt.sh
+
+After a Windows cross build, confirm the expected PE binaries:
+
+    file src/qt/agrarian-qt.exe src/agrariand.exe src/agrarian-cli.exe src/agrarian-tx.exe
+
+Documentation Status
+--------------------
+
+The preferred docs are:
+
+- `doc/build-ubuntu-24.md`
+- `doc/build-wallets.md`
+- `doc/build-windows.md`
+- `doc/dependencies.md`
+
+Older macOS, RPM, Gitian, and Travis documents remain in the tree as historical
+reference. They are not part of the verified 2.0 modernization path unless a
+document explicitly says otherwise.

 ==============
 
-Agrarian Core is extensively tested on multiple operating systems using the Linux kernel, macOS 10.10+, and Windows 7 and later.

-Microsoft ended support for Windows XP on [April 8th, 2014](https://www.microsoft.com/en-us/WindowsForBusiness/end-of-xp-support), No attempt is made to prevent installing or running the software on Windows XP, you can still do so at your own risk but be aware that there are known instabilities and issues. Please do not report issues about Windows XP to the issue tracker.

 Apple released it's last Mountain Lion update August 13, 2015, and officially ended support on [December 14, 2015](http://news.fnal.gov/2015/10/mac-os-x-mountain-lion-10-8-end-of-life-december-14/). Agrarian Core software starting with v3.2.0 will no longer run on MacOS versions prior to Yosemite (10.10). Please do not report issues about MacOS versions prior to Yosemite to the issue tracker.

 # Ubuntu Installer
 
-`installer/agrarian-installer.sh` provides a Ubuntu-only CLI for common build actions.
+`installer/agrarian-installer.sh` provides a Ubuntu-only CLI for common build
+actions. The current modernization baseline is Ubuntu 24.04 with deterministic
+`depends/`; see `doc/modernization.md` for the verified dependency set.
+
+For fresh Ubuntu hosts, prefer `contrib/agrarian-build-menu.sh` first. The menu
+script installs target-specific packages, updates the selected branch, builds
+the deterministic depends tree, and can install/start the daemon for the current
+user. This installer CLI is retained as a lower-level build tool.
 
 ## Usage
 
@@ -32,6 +39,12 @@ If wallet is enabled (default), installer preflight checks require:
 - `depends/<host>/lib/libboost_thread*.a`
 - `depends/<host>/lib/libboost_system*.a`
 
+For the current native Ubuntu Qt wallet path, depends should also provide Qt6
+pkg-config files such as `Qt6Core.pc`, `Qt6Gui.pc`, `Qt6Network.pc`, and
+`Qt6Widgets.pc`. The Linux Qt/font path also builds Expat 2.8.0 and FreeType
+2.14.3 through depends. The Windows cross-build path also uses the Qt6 depends
+target.
+
 When missing, the installer exits early and prints the exact missing path(s) plus the `make -C depends ...` command to fix them.
