v0.6.0: WebAssembly build with a WebGL backend (playable in the browser)

- ra3.webgl: a Web peer of Vulkan/Direct3D (SDL3 canvas + GLES3/WebGL2), with
  2D blit and the GPU terrain raymarch; GLSL ES shaders; null fallback off
  Emscripten. backend::webgl + default_backend() (webgl under Emscripten).
- Emscripten toolchain + Dockerfile.wasm + scripts/build-wasm.sh; import std,
  global -fexceptions, and Asyncify so the blocking frame loop yields to the
  browser (display::sleep_frame calls emscripten_sleep).
- apps/web/shell.html + apps/web/serve.py (Range-capable dev server).
- Assets: browsers forbid synchronous on-demand reads on the main thread (and
  FS.createLazyFile / the WasmFS fetch backend are worker-only; SDL3's Emscripten
  backend is main-thread DOM only, so the engine cannot run in a worker). The
  wasm build therefore preloads a compact per-map set via OPENRA3_WEB_ASSETS.
- New openra3 textures --map ID lists the loose terrain TGAs a map resolves to
  (terrain::resolve_texture_files, shared with load_textures_from_dir).
- Fixes: webgl heightmap used GL_R16 = 0x8229 (that is R8) -> upload rejected,
  terrain flattened to water; now 0x822A. Logger uses a stdout console sink on
  the web (stderr maps to console.error); a GL error check logs bad uploads.
- CI: wasm image + build jobs.

-- `Data\MapsMultiplayer.big` is read for the map catalog;

+  - with `-DOPENRA3_EXTRACT_ALL=ON` (default) also dumps **every** `.big` entry
+    plus models, textures (`.png`), sound effects/voice and movie audio via the
+    [`ra3-headless/ra3tools`](https://github.com/) scripts.
+- CMake cache vars: `RA3_GAME_DIR` (default `C:/Red Alert 3`), `RA3TOOLS_DIR`

+## Why Clang + `import std;`
+
+The engine never `#include`s the standard library: every module does
+`import std;`. CMake's support for that (`CXX_MODULE_STD`) works today with
+Clang + libc++. Linux uses the distro clang (LLVM 21); Windows cross-compiles
+with [llvm-mingw](https://github.com/mstorsjo/llvm-mingw) (clang 23 + libc++ +
+the libc++ `std` module). The two toolchains live in **separate images** so
+their compilers and standard libraries never interfere.
 
 ## Build
 
-The host needs no toolchain: build inside the container.
+The host needs no toolchain: each target builds inside its own image.

+scripts/build-linux-arm64.sh
+
+# Debian (amd64)  -> build/debian/bin/openra3 + .deb
+scripts/build-debian.sh
+
+# Debian (arm64)  -> build/debian-arm64/bin/openra3 + .deb   (cross)
+scripts/build-debian-arm64.sh
+
+# Windows (x86_64) -> build/windows/bin/openra3.exe + SDL3.dll, .zip, .msi
+scripts/build-windows.sh
+
+# Windows (arm64)  -> build/windows-arm64/bin/openra3.exe + SDL3.dll, .zip   (cross)
+scripts/build-windows-arm64.sh
+
+# WebAssembly      -> build/wasm/bin/openra3.html (+ .js/.wasm)
+scripts/build-wasm.sh
+```
+
+Every target is cross-built from x86_64 Linux in its own image: llvm-mingw for
+the Windows targets, clang + libc++ with dpkg multiarch for the arm64 targets,
+and Debian/Ubuntu-specific images for the `.deb` packages.
+
+Or drive Docker directly:
+
+```bash
+docker build --target dev -t openra3-linux:local .
+docker run --rm -v "$PWD:/work" -w /work openra3-linux:local \
+    cmake -S . -B build/linux -G Ninja -DCMAKE_BUILD_TYPE=Release
+docker run --rm -v "$PWD:/work" -w /work openra3-linux:local cmake --build build/linux -j
+docker run --rm -v "$PWD:/work" -w /work openra3-linux:local ctest --test-dir build/linux --output-on-failure

+docker run --rm -v "$PWD:/work" -w /work openra3-windows:local \
+    cmake -S . -B build/windows -G Ninja \
+        -DCMAKE_TOOLCHAIN_FILE=cmake/toolchains/llvm-mingw-x86_64.cmake \
+        -DCMAKE_BUILD_TYPE=Release
+docker run --rm -v "$PWD:/work" -w /work openra3-windows:local cmake --build build/windows -j
 ```
 
 Behind a slow or blocked mirror, pass `--build-arg APT_MIRROR=<url>`.
 
+The two images are deliberately separate so the Linux (clang + libc++) and
+Windows (llvm-mingw + MinGW SDL3) toolchains never interfere. The Windows demo
+is `build/windows/bin/openra3.exe` next to `SDL3.dll`:
+
+```powershell
+# show a real map in a Vulkan window
+openra3.exe render --game-dir "C:\Red Alert 3" --vulkan
+```
+
+Vulkan is provided by **vendored volk + headers** (`third_party/`), resolved at
+runtime, so neither image needs a Vulkan SDK.
+
+## WebAssembly
+
+OpenRA3 also builds to **WebAssembly** with Emscripten (`scripts/build-wasm.sh`),
+producing `openra3.html` + `.js` + `.wasm`. The browser gets the same GPU renderer
+as the desktop builds: a **`ra3.webgl`** backend peers with Vulkan/Direct3D — SDL3
+provides the canvas and input, and GLES 3.0 / WebGL2 runs the 2D blit and the
+terrain raymarcher (GLSL ES ports of the desktop shaders).
+
+Browsers forbid synchronous on-demand file reads on the main thread, so the
+assets are **preloaded into the module's filesystem** at build time. Bundle a
+compact per-map set (one map plus the tiles it uses) rather than the whole dump:
+
+```bash
+# 1. which loose TGAs does the map resolve to?
+openra3 textures --map map_mp_2_feasel1      # prints paths under assets/terrain
+
+# 2. stage one map + those tiles (+ maps/map_names.tsv) into a directory, then
+OPENRA3_WEB_ASSETS=/path/to/that/set scripts/build-wasm.sh

+```
+
+The engine's frame loops are blocking; the wasm build yields to the browser via
+Asyncify (`display::sleep_frame` calls `emscripten_sleep`), so the page repaints
+and handles input. Log records go to `console.log` at their real level (the
+console sink uses stdout on the web instead of stderr). Without
+`OPENRA3_WEB_ASSETS` the module still loads and starts, but exits at the menu
+because no maps are found.
+
+## Packages
+
+CPack produces the release artifacts; the Docker images and CI run it for every
+target.
+
+| Target | Portable | Installer |
+| --- | --- | --- |
+| Linux amd64 (Ubuntu 26.04) | `.tar.gz` | `openra3_<v>_amd64ubuntu26.04.deb` |
+| Linux arm64 (Ubuntu 26.04) | `.tar.gz` | `openra3_<v>_arm64ubuntu26.04.deb` |
+| Linux amd64 (Debian 13) | `.tar.gz` | `openra3_<v>_amd64debian13.deb` |
+| Linux arm64 (Debian 13) | `.tar.gz` | `openra3_<v>_arm64debian13.deb` |
+| Windows x86_64 | `openra3-<v>-windows-x86_64.zip` | `openra3-<v>-windows-x86_64.msi` |
+| Windows arm64 | `openra3-<v>-windows-arm64.zip` | (WiX-only; see below) |
+
+The `.deb` dependencies are derived from the binary with `dpkg-shlibdeps`. The
+`.msi` is built with **wixl** (msitools) straight from the Linux cross image;
+wixl 0.106 has no arm64 support, so Windows/ARM64 ships the portable `.zip`
+(the MSI toolchain for ARM64 would be WiX v4 via the .NET SDK).
+
+## Logging
+
+Every run writes `openra3.log` next to the executable through the vendored
+[`libenderlog`](third_party/libenderlog) module (`import ender.log;`). A file
+sink archives the previous log to `openra3.log.<YYYYmmdd-HHMMSS>` on open, so
+each run gets its own file; the active file rotates at 4 MiB and the last 10
+archives are kept. Records at **`warn` and above** carry a call stack (Windows
+`CaptureStackBackTrace` / POSIX `execinfo`, because libc++ has no
+`<stacktrace>`). A hard crash also writes `openra3_crash.log` with the faulting
+module and a raw backtrace.
+
 ## Running a skirmish
 
 ```bash
 # list the maps in your install
-docker run --rm -v "/path/to/Red Alert 3:/game:ro" openra3-dev:local \
-    ./build/bin/openra3 maps --game-dir /game
+docker run --rm -v "/path/to/Red Alert 3:/game:ro" openra3-linux:local \
+    /work/build/linux/bin/openra3 maps --game-dir /game
 
 # play a headless skirmish on a real map
-docker run --rm -v "/path/to/Red Alert 3:/game:ro" openra3-dev:local \
-    ./build/bin/openra3 skirmish --game-dir /game --map map_mp_2_feasel4 --seed 7
+docker run --rm -v "/path/to/Red Alert 3:/game:ro" openra3-linux:local \
+    /work/build/linux/bin/openra3 skirmish --game-dir /game --map map_mp_2_feasel4 --seed 7
 ```
 
+The Windows build is a native `openra3.exe` — copy it next to `SDL3.dll` and run
+it from `cmd`/PowerShell, e.g. `openra3.exe skirmish --game-dir "C:\Red Alert 3"`.
+
 `--frames N` caps the simulation length (default 15 minutes of game time at
 30 Hz). The result is deterministic for a given map and seed.
 
+## Menu
+
+Run `openra3` with no arguments (or `openra3 menu`) to open a window listing the
+maps by their **localized display name** (read from the install's
+`gamestrings.csf`, e.g. `map_mp_2_feasel4` → "Battlebase Beta") with their id
+below. The `Options` column exposes every `render`/`skirmish` parameter — mode
+(3D terrain / top-down / skirmish), window size, camera pitch/yaw/height, FOV,
+zoom, terrain scale, terrain pitch, world size, seed, frame cap, the overview
+thumbnail toggle and a BMP output path. `Up`/`Down` selects, `Left`/`Right`
+changes a value (or moves the text caret on the BMP field), `Tab` switches
+between the map list and the options, `Enter` starts and `Esc` quits. Starting a
+3D or top-down view opens the viewer; closing it returns to the menu. When no
+window backend is available the same flow falls back to a console picker, and
+`openra3 menu-preview` renders one menu frame to a BMP for inspection.
+
 ## Rendering the map
 
-The renderer draws the map's own overview art, a world grid and the match state
-(start markers in yellow, player 0 in blue, player 1 in red).
+`render` draws the **real terrain**: it parses the map's `HeightMapData`
+(elevation grid) and `BlendTileData` (per-cell tile index plus the per-cell
+`Blends`/`ThreeWayBlends` and their `BlendDescription`s), loads the tile
+textures from `Data\Terrain.big` (RefPack + TGA), and rasterises the map with an
+elevation shade. Each cell cross-fades into its blend neighbour with the same
+linear ramp the retail `Terrain.fx` uses, so material transitions are smooth; on
+the GPU path the tile atlas is padded with a replicated gutter so filtering
+never bleeds between tiles. Match state is overlaid (start markers in yellow,
+player 0 in blue, player 1 in red). `--thumbnail` uses the old `<map>_art.tga`
+overview instead.
 
 **Offscreen image** (works anywhere, no display needed):
 
 ```bash
-docker run --rm -v "/path/to/Red Alert 3:/game:ro" -v "$PWD/out:/out" openra3-dev:local \
-    /work/build/bin/openra3 render --game-dir /game --map map_mp_2_feasel4 --out /out/map.bmp
+docker run --rm -v "/path/to/Red Alert 3:/game:ro" -v "$PWD/out:/out" openra3-linux:local \
+    /work/build/linux/bin/openra3 render --game-dir /game --map map_mp_2_feasel4 --out /out/map.bmp
 ```
 
-**Interactive window** (SDL3; drag to pan, wheel to zoom, Esc to quit). In a
-container you need an X server on the host — on Windows run
+On Windows the same command runs natively: `openra3.exe render --game-dir
+"C:\Red Alert 3" --map map_mp_2_feasel4` opens an SDL3 window.
+
+**Interactive window** (Vulkan with `--vulkan`, otherwise SDL3). The camera
+follows the retail tactical view: it opens centred on the first player's start,
+the wheel zooms, pushing the cursor against a screen edge scrolls, dragging with
+the left button pans, and Esc quits. `--zoom Z` sets the initial zoom (1 fits
+the whole map). In a container you need an X server on the host — on Windows run
 [VcXsrv](https://sourceforge.net/projects/vcxsrv/) and launch it with "Disable
 access control", then:
 
 ```bash
 docker run --rm -v "/path/to/Red Alert 3:/game:ro" -e DISPLAY=host.docker.internal:0.0 \
-    openra3-dev:local /work/build/bin/openra3 render --game-dir /game --map map_mp_2_feasel4
+    openra3-linux:local /work/build/linux/bin/openra3 render --game-dir /game --map map_mp_2_feasel4
 ```
 
 If no display is available the viewer falls back to writing `openra3_view.bmp`.

-# Architecture
+# Architecture & Master Plan
 
-OpenRA3 is organised as a stack of C++ modules. Each layer may import the ones
-below it, never the ones above.
+OpenRA3 is a from-scratch, portable re-implementation of **Command & Conquer:
+Red Alert 3** (SAGE 2.0) in **pure C++26** — C++ modules, `import std;`, no
+scripting language, no managed runtime, no other programming language anywhere
+in the tree. It is built with Clang + libc++ on Linux and cross-compiled to
+Windows with llvm-mingw.
+
+This document is two things at once:
+
+1. the **layer architecture** (how the modules sit on top of one another), and
+2. the **master plan** — the complete Red Alert 3 feature set decomposed three
+   levels deep into **Module → Function → Feature**, each tagged with its
+   implementation status and target milestone.
+
+The decomposition is the contract: every feature RA3 has is either implemented,
+being implemented, or explicitly planned here. Nothing is silently dropped.
+
+> **Scope.** Offline only. Single-player campaign, skirmish, Commander's
+> Challenge and LAN lockstep — never an online service, matchmaking, EA account
+> or GameSpy/Steam integration. The simulation is deterministic and
+> self-contained. No game assets or binaries are shipped; the engine reads the
+> user's own install at runtime.
+
+---
+
+## 1. Principles
+
+Same five rules as the rest of the tree, restated because the plan is written
+against them:
+
+1. **Pure C++.** One language. No Lua, no JS, no C#, no Python at runtime.
+   Python is allowed *only* in offline build tooling (`tools/`, cmake helper
+   scripts), never linked into `openra3`.
+2. **No raw owning pointers.** Ownership is `std::unique_ptr`; cross-references
+   are non-owning views (`thing *`, handles, indices).
+3. **Portable simulation.** No platform API in the foundation or simulation
+   layers. All platform concerns live behind `display` / `audio` / `video`.
+4. **Determinism.** Anything that can diverge between runs (RNG, iteration
+   order, float accumulation, hash order) is explicit, seeded and testable.
+5. **RE-traceable.** Every structure or constant taken from the retail
+   `ra3_1.12.game` (image base `0x400000`) or from the GPLv3 SAGE 1.0 reference
+   cites its origin. No asserted fact without a source.
+
+---
+
+## 2. Layer architecture
+
+Each layer may import the ones below it, never the ones above. The `ra3`
+umbrella module re-exports the SDK; applications import `ra3` only.

-## Module responsibilities
+The current concrete modules (`ra3.core`, `ra3.logic`, `ra3.data`,
+`ra3.skirmish`, `ra3.fs`, `ra3.map`, `ra3.terrain`, `ra3.render`, `ra3.ui.*`,
+`ra3.vulkan.*`, `ra3.dx.*`, `ra3.webgl.*`, `ra3.display`, `ra3.game`, `ra3.client`, and the
+vendored `ender.log`) are the **seeds** of the
+target modules below. `ra3.skirmish` and `ra3.game` will be absorbed into
+`ra3.ai` / `ra3.match`; new modules are added as their subsystems are recovered.
 
-### `ra3.core`
-The vocabulary every other module shares, mirroring SAGE's `GameEngine/Common`:
-`real`/`int32`/`uint32`, `coord3d`/`coord2d`/`rgb_color`, `ascii_string` +
-`make_name_key`, the deterministic `random` stream, and the `message_stream`
-command bus (node layout derived from retail `MessageStream::appendMessage`,
-`0x0060c4a0`).
+### Status legend
 
-### `ra3.logic`
-The deterministic simulation, mirroring SAGE's `GameLogic`: `thing` → `object`
-with pluggable `update_module`s, `player`/`player_list`, the `partition_manager`
-spatial grid, and the 30 Hz `game_logic` driver (`prepare_new_game` /
-`start_new_game` / `update`).
+| Tag | Meaning |
+| --- | --- |
+| `[x]` | implemented and tested on `main` |
+| `[~]` | partially implemented / works for the happy path |
+| `[ ]` | planned, not started |
+| `(vX.Y)` | target milestone (see the roll-up in §5) |
+| `!!` | needs reverse engineering before it can be built |
 
-### `ra3.client`
-The presentation boundary: an abstract `display` with a `headless_display`
-implementation, and `game_client`, the seam a future W3D/D3D9 renderer plugs
-into.
+| Function tag | Meaning |
+| --- | --- |
+| `D` | **done** — the function's features are largely present |
+| `P` | **partial** — some features present |
 
-### `ra3.game`
-Red Alert 3 data that SAGE keeps in `PlayerTemplate`: the three sides
-(`faction` flags `Empire=2`, `Allied=4`, `Soviet=8`, `Random=7`, recovered from
-the retail skirmish setup) and skirmish defaults.
+---
 
-### `ra3.fs`
-Reading the user's installation. Implements the `BIG4` archive container and
-EA's RefPack codec, plus `find_game_dir` (`--game-dir` / `$RA3_GAME_DIR` /
-`C:\Red Alert 3`). Only the archive index is held in memory; payloads are read
-on demand.
+## 3. Master plan — Module → Function → Feature
 
-### `ra3.map`
-Map discovery and loading: scans `MapsMultiplayer.big` for main map entries,
-unwraps the two compression layers (`BIG4` RefPack → `EAR\0` wrapper → RefPack →
-`CkMp`), and recovers `Player_N_Start` waypoint coordinates. Degenerate
-extractions are rejected so the caller can fall back.
+### M00 `ra3.core` — foundation vocabulary `[D]`
 
-### `ra3.skirmish`
-The minimal match: two players, unit classes (harvester/infantry/tank/base),
-passive + harvester income, a simple build AI, movement and combat on a fixed
-30 Hz step, and a base-destruction win condition. Fully deterministic.
+Mirrors SAGE `GameEngine/Common`. Everything else speaks this.
 
-### `ra3.render`
-A dependency-free software renderer: an ARGB8888 `image` framebuffer with
-blit/line/circle primitives, a TGA decoder for the game's map art, a 24-bit BMP
-encoder for headless output, and `compose` which overlays a world grid and
-markers (start positions, live units) onto the map art.

+
+## 4. Cross-cutting invariants
+
+These hold across **every** module above and are enforced in review:
+
+1. **Language** — runtime code is C++ only. Build tooling may use Python.
+2. **Ownership** — no raw owning pointers; `unique_ptr` for ownership, handles or
+   `thing *` views for references.
+3. **Layering** — a module imports only lower layers. `ra3.core` imports no
+   engine module and no platform API.
+4. **Determinism** — RNG, iteration, hashing and float use are explicit and
+   seedable; the logic step must be bit-reproducible for a given input stream.
+5. **RE-traceable** — retail structure/constant changes cite an address in
+   [`REVERSE_ENGINEERING.md`](REVERSE_ENGINEERING.md).
+6. **Offline** — no online service; LAN lockstep (M25) is the only networking,
+   and only command exchange.
+7. **No bundled assets** — game data is read from the user's install; nothing
+   from it is committed. The tree builds and runs in CI on a built-in test map.
+
+---
+
+## 5. Milestone mapping
+
+The plan rolls up to these releases:
+
+| Milestone | Modules advanced | Delivers |
+| --- | --- | --- |
+| `v0.3.x` (done) | M00, M01, M04, M05(F1–F3), M06, M07(partial), M08(partial), M10(partial), M16(F3,F8), M17, M18 | minimal deterministic skirmish, real terrain, Vulkan present, menu |

+
+## 6. Design rules
+
+The five rules the codebase is held to (restated from §1, with the concrete
+consequences that trip people up):
 
 1. **No raw owning pointers.** Ownership is `std::unique_ptr`; the partition
-   manager holds non-owning `thing *` views only.
-2. **Portable simulation.** No platform APIs in `ra3.core` / `ra3.logic`. All
-   platform concerns live behind `display`.
+   manager and object registry hold non-owning `thing *` views only.
+2. **Portable simulation.** No platform APIs in `ra3.core` / simulation
+   modules. All platform concerns live behind `display`.
 3. **Determinism.** Anything that can diverge between runs (random, iteration
    order) is explicit and seedable.
 4. **RE-traceable.** Where a structure or constant comes from the retail
    binary, the address is cited in the comment.
 5. **No bundled assets, no online.** Game data is read from the user's install
    and never committed; there is no networking or online service.
+
+---
+
+## 7. Where to start
+
+- New to the codebase: read this plan top-to-bottom (§3 is the feature set,
+  §5 the near-term order of work).
+- Picking up a feature: find its **Function** above, take the lowest-numbered
+  unmet `[ ]` **Feature**, and cite its supporting retail address.
+- Reverse engineering a subsystem: follow the loop in
+  [`REVERSE_ENGINEERING.md`](REVERSE_ENGINEERING.md); the `!!` tags above mark
+  the functions that still need a recovery pass before they can be built.

+
+The in-game camera is the `TheTacticalView` object, held in the global at

 `Player_2_Start` = `(1290.8, 1404.9, 0)`.
 
+### Terrain (`ra3.terrain`)
+
+The `CkMp` tree is a flat chunk list: `"CkMp"`, `u32 assetCount`, the name
+table (`{ u8 len, name, u32 index }`, index descending from `assetCount`), then
+`{ u32 index, u16 version, u32 size, data }` per chunk. On
+`map_mp_2_feasel4` the terrain is `HeightMapData` v6 (540 x 600, border 20,
+`u16` elevations, scale `0.0390625`) and `BlendTileData` v27.
+
+`BlendTileData` opens with `NumTiles`, the `u16` tile grid, then the
+blend/three-way/cliff tables (`u16` for v27); the passability flag arrays that
+follow are not needed for rendering, so the texture table is located by
+scanning for its `{ cellStart, cellCount, cellSize, magic }` + `u16`-prefixed
+name entries. A tile value is `(cellIndex << 2) | variant`, and `cellIndex`
+indexes the global `TextureCellCount`-cell table (each texture owning
+`cellSize^2` 64 px cells). The textures themselves are
+`art\terrain\<stem>.tga` in `Terrain.big` / `Core11.big` (RefPack + 256x256
+TGA). Rendered top-down, `map_mp_2_feasel4` correlates 0.94 with the official
+`_art.tga` overview.
+
+### Terrain blending (`BlendTileData` tail)
+
+After the tile grid, `BlendTileData` stores three per-cell `u16` tables —
+`Blends`, `ThreeWayBlends` and `CliffTextures` — then `TextureCellCount`,
+`BlendsCount`, the texture table, two magic words and `BlendsCount - 1` blend
+descriptions (18 bytes each: `u32 secondaryTile`, four direction bytes,
+`u8 flags`, `u8 twoSided`, `u32 0xFFFFFFFF`, `u32 0x7ADA0000`). A non-zero
+`Blends[cell]` is a 1-based index into the descriptions; `secondaryTile` is a
+packed tile value (`secondaryTile >> 2` is its cell).
+
+The retail `Terrain.fx` (compiled `terrain.fxo`, parameters `Terrain.BaseTexture`,
+`Terrain.MacroTexture`, `MapCellSize`, `IsTerrainAtlasEnabled`; technique
+`TerrainTile`) cross-fades a cell's base tile into `secondaryTile` with a linear
+ramp selected by `BlendDirection`: `1` right, `2` top, `4` top-right, `8`
+top-left, where `flags` bit 0 flips the axis and bit 1 marks a two-sided
+diagonal. OpenSAGE's `Terrain.frag` reconstructs the exact
+`CalculateBlendFactor`; `ra3::terrain::blend_factor` and `shaders/terrain.frag`
+mirror it. The row axis is *not* inverted (73% of long-axis blends point at a
+neighbour of the same texture, versus 25% inverted). On `map_mp_2_feasel4`,
+33828 of 324000 cells carry a blend and there are 7094 descriptions.
+
+The GPU atlas pads every 64 px tile with a 2-texel replicated gutter. Packed
+edge-to-edge, bilinear/mipmap filtering averaged two unrelated tiles at every
+cell border — that cross-tile bleed was the visible grid line the hardware path
+drew. (`shaders/terrain.frag` samples `cell_stride = cell_texels + 2 * gutter`.)
+
+### Open question: per-cell tile sampling
+
+Measured on `map_mp_2_feasel4`, sampling each cell as its own 64 px block and
+restarting the UV every cell leaves a 1.39x edge spike at cell boundaries
+(43.4 vs 31.1 mean gradient at 8 px/cell). Two candidate mappings reduce it and
+need a visual decision against the retail art:
+
+| Mapping | Boundary/interior |
+| --- | --- |
+| per-cell 64 px block (current) | 1.39 |
+| OpenSAGE `BlendTileTextureIndex` Morton layout, 32 px block | 1.18 |
+| continuous `uv / (cellSize * 2)`, per OpenSAGE `Terrain.frag` | 1.11 |
+
+The retail `Terrain.frag` (OpenSAGE) samples the tile texture *continuously*
+(`uv / (CellSize * 2)`), so adjacent cells never restart the texture; our
+per-cell restart is the remaining source of grid lines. Switching the atlas
+from 64 px blocks to continuous 32 px regions (or the Morton 8x8 layout) is the
+next step, pending an art correlation check.
+
+### Map display names
+
+The skirmish map list labels live in `Data\English.big`'s
+`data\gamestrings.csf` (the newest `Lang-English*.big` wins) under
+`MAP:<UPPERCASE_ID>`, e.g. `MAP:MAP_MP_2_FEASEL4` = "Battlebase Beta". CSF
+values are UTF-16 code units whose low byte is XORed with `0xFF`
+(`ra3::map::parse_map_names`). `openra3 extract` writes the decoded table to
+`maps/map_names.tsv`; `openra3 menu` shows them instead of the raw map id.
+
+

-# Roadmap
-
-OpenRA3 is a very large undertaking. This roadmap is deliberately honest about
-scope: reconstructing a 2008 RTS engine from a decompiler plus a related open
-engine is a multi-year, multi-person effort. The milestones below are ordered so
-that each one produces something that builds and runs.
-
-## Done
-
-- [x] **v0.0.1 — skeleton + minimal skirmish.** C++26 modules, GCC 16,
-      CMake/Ninja, Docker `dev`/`deploy`, GitLab CI. Reads `BIG4`/RefPack data
-      from a local install, recovers map start waypoints, and runs a
-      deterministic headless two-player skirmish to a decision.
-- [x] **v0.1.0 — map renderer + window.** Software ARGB framebuffer, TGA
-      decoder for the map art, BMP output, map/grid/unit compositing, and an
-      SDL3 window viewer (pan/zoom).
-
-## Next
-
-- [ ] **v0.1.1 — correct world calibration.** Parse the map heightmap
-      dimensions (and `MPPositionList` starts) so the unit overlay lines up with
-      the map art instead of using an assumed world size.
-- [ ] **v0.2.0 — data & file formats.** Parse compiled gameplay assets
-      (`GameObject`, `WeaponTemplate`, `ArmorTemplate`, `LocomotorTemplate`) so
-      units use the real balance numbers instead of OpenRA3's stand-ins.
-- [ ] **v0.3.0 — deterministic simulation.** Real update modules, locomotor
-      movement, weapons/damage/armour resolution, build queues and the tech
-      tree, pathfinding and shroud.
-- [ ] **v0.4.0 — AI.** Skirmish AI: build states, team composition, attack
-      waves (the reference tree's `AI*` modules).
-- [ ] **v0.5.0 — full renderer.** Terrain heightmap rendering, W3D models and a
-      D3D9/Vulkan/OpenGL client backend implementing `ra3::client::display`,
-      plus full input.
-- [ ] **v0.6.0 — content.** Load real maps, units, powers and strings; play a
-      skirmish end-to-end with a UI.
-
-## Cross-cutting tracks
-
-- **RE depth** — keep recovering retail layouts (see
-  [`REVERSE_ENGINEERING.md`](REVERSE_ENGINEERING.md)); every structure gets an
-  address citation and a test.
-- **Determinism & replay** — the logic random stream and frame ordering must be
-  reproducible; replay format and a golden-replay test suite.
-- **Offline only** — no online mode. Multiplayer, if pursued, is LAN lockstep on
-  the message stream, never an online service.

  * The presentation layer: an abstract output surface plus the client facade
  * that owns the simulation and drives the frame loop.
  *
- * A future W3D/D3D9 backend implements the same `display` interface; the
- * default headless backend keeps OpenRA3 runnable on a CPU-only box.
+ * Backends implement only the low-level primitives (`init`, `present`,
+ * `poll_event`, `window_size`, `key_down`, `shutdown`) and, optionally,
+ * `present_terrain`; the interactive loops (menu, image viewer, camera viewer,
+ * GPU terrain) and the loading screen live here once, so input mapping and the
+ * frame loop never diverge between the SDL and Vulkan backends. The loops
+ * assume the display is already initialized, which lets one window host a menu,
+ * a loading bar and a viewer in sequence.

+# libenderlog
+
+A standalone C++26 logging library, built as a C++20/26 **module** (`import ender.log;`)
+with **`std::stacktrace`** call-stack capture on severe records.
+
+It was extracted from the `ender-physics` engine, where it started life as
+`ender.log`, and turned into a library that has no other dependency — not on the
+engine, not on a logging framework.
+
+## Features
+
+- **Leveled records.** `trace`, `debug`, `info`, `warn`, `error`, `critical`,
+  filtered by an atomic `minimum` check that is cheap enough to guard expensive
+  message construction: `if (log::enabled(log::level::debug)) { ... }`.
+- **Source location.** Every record carries the file, line and function of the
+  caller, taken from `std::source_location` at the call site — exact even in a
+  stripped release binary, because it is a compile-time constant.
+- **Call stacks.** Records at or above `options::stacktrace_from` carry a
+  formatted `std::stacktrace`. The frames belonging to the library itself are
+  stripped by symbol, so the first reported frame is the caller regardless of
+  the optimisation level (the level wrappers get inlined away under `-O`).
+- **Pluggable sinks.** A `console_sink` (stderr by default) and a `memory_sink`
+  (for tests and in-game consoles) ship; `sink` is a small interface.
+- **File output with archiving.** `file_sink` writes to a file and, on open,
+  moves an existing log aside to a timestamped archive, so a run never appends
+  onto a previous run's log. It can also rotate by size and bound how many
+  archives are kept.
+- **No stacktrace? No problem.** Where `<stacktrace>` is missing (libc++, and
+  therefore every cross target), the module still compiles and records still
+  carry their call site — they simply have no stack.
+
+## Requirements
+
+C++26 modules and `import std;` need a recent toolchain:
+
+| Requirement | Version |
+|---|---|
+| Compiler | **GCC 15+** (or Clang with a standard library that provides the `std` module) |
+| CMake | **3.30+** (for `CMAKE_EXPERIMENTAL_CXX_IMPORT_STD`) |
+| Standard library | libstdc++ for `std::stacktrace` |
+
+Ubuntu 26.04's default `g++` (GCC 15) and CMake 4 satisfy this, and that is the
+release the CI targets and the `.deb` is built for. Ubuntu 24.04 ships GCC 13 and
+CMake 3.28 and cannot build `import std;` without extra toolchains, so it is not
+supported.
+
+## Building
+
+```sh
+cmake -S . -B build -G Ninja -DCMAKE_BUILD_TYPE=Release
+cmake --build build -j
+ctest --test-dir build --output-on-failure
+```
+
+Options:
+
+| Option | Default | Description |
+|---|---|---|
+| `ENDERLOG_WERROR` | `OFF` | Treat warnings as errors |
+| `ENDERLOG_BACKTRACE_SYMBOLS` | `ON` | Link executables with `-rdynamic` so traces can name frames |
+| `ENDERLOG_BUILD_TESTS` | `ON` | Build the test suite |
+| `ENDERLOG_BUILD_EXAMPLES` | `ON` | Build the example program |
+
+Build Debug or RelWithDebInfo when you need to read a trace: frame names come
+from debug information, and a release build often reports application frames as
+`<unknown>`.
+
+## Using the library
+
+### `add_subdirectory`
+
+```cmake
+add_subdirectory(libenderlog)
+target_link_libraries(my_app PRIVATE enderlog::enderlog)
+```
+
+### Installed package
+
+```cmake
+find_package(enderlog REQUIRED)
+target_link_libraries(my_app PRIVATE enderlog::enderlog)
+```
+
+The static archive is installed together with the module interface source
+(`ender.log.cppm`) because a module's BMI is compiler-version-specific — the
+consumer rebuilds it from the source.
+
+### In code
+
+```cpp
+import std;
+import ender.log;
+
+namespace log = ender::log;
+
+auto main() -> int {
+    log::configure({.minimum = log::level::debug, .stacktrace_from = log::level::warn});
+
+    log::info(std::format("body {} moved to {:.2f}", 7, 12.35)); // formatted by the caller
+    log::error("a body left the world");                          // carries a stack trace
+}
+```
+
+Example output:
+
+```
+[11:32:18] ERROR    example: a body left the world  (examples/main.cpp:8)
+    #0  simulate_one_step (examples/main.cpp:8)
+    #1  main (examples/main.cpp:20)
+    #2  <unknown>
+    #3  __libc_start_main
+    #4  _start
+```
+
+### Configuration
+
+```cpp
+log::configure({
+    .minimum = log::level::debug,          // drop everything below this
+    .stacktrace_from = log::level::error,  // capture a stack at/above this
+    .stacktrace_depth = 16,                // max frames kept
+    .stacktrace_skip = 2,                  // frames dropped before the caller is found
+});
+```
+
+`log::current_options()` reads it back, `log::add_sink(...)` adds a destination,
+and `log::set_sinks({...})` replaces them.
+
+### Writing to a file
+
+```cpp
+namespace log = ender::log;
+
+// Archive any existing enderlog.log to enderlog.log.<timestamp>, then start a
+// fresh file for this run. Rotate at 64 KiB and keep the last 5 archives.
+auto sink = log::add_file_sink("enderlog.log", {.max_file_size = 64 * 1024, .max_archives = 5});
+```
+
+- **No appending onto a previous run.** On open, an existing non-empty
+  `enderlog.log` is renamed to `enderlog.log.<YYYYmmdd-HHMMSS>` before the new
+  file is created, so every run gets its own file and the previous run's log is
+  preserved. A leftover empty file is simply replaced.
+- `file_options::max_file_size` (0 disables) rotates the active file mid-run the
+  same way, and never archives an empty file. `file_options::max_archives`
+  (0 keeps all) deletes the oldest archives beyond the limit.
+- `file_options::flush_each_record` (on by default) flushes after every record so
+  a crash keeps the tail.
+- `add_file_sink` adds the sink to the global logger and returns it; `path()` and
+  `archives()` expose what it wrote. The `file_sink` class can also be used
+  directly and installed with `set_sinks`.
+
+## Packaging
+
+`cpack` produces a Debian package:
+
+```sh
+cmake -S . -B build -DENDERLOG_DISTRO=ubuntu26.04
+cmake --build build -j
+cd build
+cpack
+# -> libenderlog-dev_0.0.1_amd64_ubuntu26.04.deb
+```
+
+The package installs the static archive, the module interface source and the
+CMake package config. CI builds it for Ubuntu 26.04 and publishes it as a job
+artifact.

+//               or vk_icdNegotiateLoaderICDInterfaceVersion.
+//   Version 1 - Add support for vk_icdGetInstanceProcAddr.
+//   Version 2 - Add Loader/ICD Interface version negotiation
+//               via vk_icdNegotiateLoaderICDInterfaceVersion.
+//   Version 3 - Add ICD creation/destruction of KHR_surface objects.
+//   Version 4 - Add unknown physical device extension querying via
+//               vk_icdGetPhysicalDeviceProcAddr.
+//   Version 5 - Tells ICDs that the loader is now paying attention to the
+//               application version of Vulkan passed into the ApplicationInfo
+//               structure during vkCreateInstance.  This will tell the ICD
+//               that if the loader is older, it should automatically fail a
+//               call for any API version > 1.0.  Otherwise, the loader will
+//               manually determine if it can support the expected version.
+//   Version 6 - Add support for vk_icdEnumerateAdapterPhysicalDevices.
+//   Version 7 - If an ICD supports any of the following functions, they must be
+//               queryable with vk_icdGetInstanceProcAddr:
+//                   vk_icdNegotiateLoaderICDInterfaceVersion
+//                   vk_icdGetPhysicalDeviceProcAddr
+//                   vk_icdEnumerateAdapterPhysicalDevices (Windows only)
+//               In addition, these functions no longer need to be exported directly.
+//               This version allows drivers provided through the extension
+//               VK_LUNARG_direct_driver_loading be able to support the entire
