api upgrades, windows dev tools, and android fixes (#299)

* pop up a fake save

* add CI to dev branch

* Make ROM-free test tiers actually run on Windows (#267)

Suite discovery, the extension-point catalog scan, mod test-dir pickup,
and the meta-coverage corpus all shelled out to ls/find/test -d, which do
not exist in cmd.exe. Every listing came back empty on Windows, so tiers
ran 0 suites and still reported ALL TESTS PASSED.

Add portable probes to tests/fs_io.lua (same Unix commands on
Linux/macOS; dir /b and a shell-free rename-self existence check on
Windows) and rewire the four call sites to them. 15/15 engine suites and
2/2 modkit suites now genuinely run and pass on Windows.

Fixes #266

+# Launcher
+
+The launcher is `src/import/RomImporter.lua`, the first-run / title screen
+that runs before `Game:load`. Besides ROM import (see the file's own header)
+it hosts a tabbed shell covering per-game save slots and a mod manager. This
+file documents the runtime model; the visual spec lives separately.
+
+## Android multi-ROM / mod / save import
+
+On Android, `love.system.pickFile([kind])` opens the Storage Access Framework
+picker (`GameActivity.showFilePicker`); the chosen file is copied into the app
+save directory as:
+
+| `kind` | Destination |
+| --- | --- |
+| nil / `"rom"` | `picked_rom.gb` (open) |
+| `"mod"` | `picked_mod.zip` (open) |
+| `"sav"` / `"save"` | `picked_save.sav` (open) |
+
+Export uses a separate API: `love.system.createFile(suggestedName)` →
+`GameActivity.showCreateDocument` (`ACTION_CREATE_DOCUMENT`), which copies
+staged `pending_export.sav` to the user-chosen URI and writes `export_done.flag`
+for the launcher to acknowledge on refocus.
+
+`RomImporter` then imports on refocus / Choose:
+
+- **ROMs** via `findPendingRom`: only a 1 MiB `.gb` whose SHA-1 maps to a
+  version that is **not** yet ready counts as pending. A leftover
+  `picked_rom.gb` from Red therefore cannot block Blue's Choose (issue #167).
+- **Mods** via `findPendingMod`: Prefer `picked_mod.zip`, or (on Choose) any
+  other `.zip` at the save-dir root (USB copy).
+- **Saves** via `findPendingSav`: Prefer `picked_save.sav`, or (on Choose) any
+  other `.sav` at the save-dir root.
+
+After a successful import the consumed save-dir file is removed.
+
+**Manual check (device/emulator):** import Red → switch to Blue → Choose →
+system file picker must appear (not a silent Red re-extract) → pick Blue →
+Blue becomes ready beside Red. On the MODS tab, Import mod .zip must open the
+same system picker and install the chosen archive on return.
+
+## Tab structure
+
+`self.tab` is one of `"red"`, `"blue"`, `"yellow"`, `"mods"`. The tab bar
+draws one chip per game plus a MODS chip and rebuilds `self.tabRects` every
+frame so `mousepressed` can dispatch clicks; switching tabs mid-import is
+allowed (a dropped ROM still routes by SHA-1 regardless of which tab shows).
+
+- A game tab (`_drawGamePanel`) shows the ROM card, the SAVE FILES card, the
+  Play button, and the SAVE SLOT card in a responsive two-column grid (see
+  Responsiveness). The MODS tab (`_drawModsPanel`) shows the mod list instead.
+- The self-updater banner (`self.Check`, see `docs/updater.md`) draws as a
+  centered pill in a reserved band just above the footer, on every tab. That
+  position is unchanged by this redesign, so `docs/updater.md` needed no edits.
+
+## Save slot model
+
+All slot I/O lives in `src/core/SaveData.lua` and goes through the same fs
+abstraction (`persistFs`) every other save/options call uses, so portable
+mode (an `io.*` filesystem used when `portable.txt` marks the install)
+keeps working unchanged.
+
+- **Files.** A version's playthroughs live under `saves/<version>/`, one file
+  per slot: `saves/<version>/slot1.lua` plus a rolling `.bak` and staged
+  `.tmp` witness (`slotNames`), mirroring the write/recovery discipline
+  `SaveData.save`/`load` already use for the flat legacy file. Slot ids match
+  `slot%d+`; `createSlot` allocates one past the highest existing number so a
+  reused id can never collide with a lingering file.
+- **Registry.** The ordered slot list and which one is active persist in
+  `options.lua` (via the existing `SaveData.loadOptions`/`saveOptions`):
+  `options.saveSlots = { [version] = { list = {"slot1", ...}, active = "slot1" } }`.
+- **Active slot resolution.** `saveNames(version)`, the function every
+  existing caller (`TitleState` hasSave/load/save, recovery order) already
+  goes through, now resolves the *active* slot instead of a fixed flat name.
+  Resolved once per version per process (`ensureVersionSlots`, cached in
+  `activeSlotCache`/`slotsChecked`): a registry entry wins; otherwise a lazy
+  legacy migration may create one; otherwise the flat legacy path is used
+  (`save.lua` / `save_blue.lua`), so a pre-slots install keeps working as before.
+- **Legacy migration.** One-time per version, lazy on first
+  `listSlots`/`load`/`saveNames` call (`tryMigrateLegacy`): if a flat legacy
+  file exists and no `saves/<version>/` registry does, its main + `.bak` are
+  copied into `saves/<version>/slot1.lua(.bak)`, verified readable
+  (`decodeSlot`: main, then `.tmp`, then `.bak`), and only then are the
+  originals removed and `slot1` registered as active. A copy that fails to
+  verify leaves the originals in place; migration never loses data.
+
+The launcher-facing API:
+- `SaveData.listSlots(version)` -> array of `{id, exists, name, meta}` for
+  every registered slot. `name` is the save's player name, or `nil` for an
+  empty slot; `meta` is `{badges, timeText, dexCount}` (the same fields the
+  title screen's `ContinueInfo` shows) or `nil`. The pure part,
+  `SaveData.slotSummary(save)`, is unit-testable with no filesystem.
+- `SaveData.setActiveSlot(version, slotId)` registers the id if new, persists
+  it as active, and updates the process cache so the very next save/load
+  lands there. The launcher calls this the moment a slot row is clicked
+  (`RomImporter:_selectSlot`); pressing Play needs no signature change, since
+  `Game.lua`/`main.lua` still just call `SaveData.load()`/`save()`.
+- `SaveData.createSlot(version)` -> new slot id, registered but with **no
+  save file written**. An empty slot means the title screen offers NEW GAME
+  only, which needs no further changes.
+- `SaveData.deleteSlot(version, slotId)` removes the slot's
+  main/`.bak`/`.tmp` files, drops it from the registry, and if it was active
+  points active at another remaining slot (or clears active when the list is
+  empty). The launcher's SAVE SLOT panel Delete control calls this.
+
+## Launcher mod manager
+
+`src/mods/LauncherMods.lua` is a launcher-only read of the mod set. It runs
+before `Game:load`, so **it never loads a mod's entry chunk**; only
+`manifest.json` is read and validated (`src/mods/Manifest.validate`), the way
+`Loader:_discover` finds mods without running them. The real loader
+(`src/mods/Loader.lua`) still owns the actual load at boot.
+
+- `LauncherMods.list()` scans `mods/` one level deep (first id wins on a
+  duplicate) and returns one row per mod:
+  `{id, name, version, badge, description, enabled, status, statusDetail}`.
+  `badge` is the manifest's `category`, falling back to `profile`, then
+  `"MOD"`, uppercased. `enabled` reads `options.mods[id]` (missing means
+  enabled, matching the loader's own default).
+- `status` is `"ok"`, `"warn"`, or `"conflict"`, computed by the pure
+  `LauncherMods.deriveList`/`statusFor` against `ManagerState.resolveToggle`
+  and the validated manifests: `conflict` when enabling this mod collides
+  with another enabled one; `warn` for an out-of-range `game_version` or an
+  absent/disabled/wrong-version hard dependency; `ok` otherwise. Having no
+  `love.*` calls, this half is table-driven by the test suite on its own.
+- `LauncherMods.setEnabled(id, bool)` persists `options.mods[id]` as a plain
+  boolean, the exact shape `Loader:_saveState` writes, so the running game
+  and the in-game `ManagerState` see the change on next boot. The mods panel
+  calls this on every toggle and re-derives the list right away
+  (`RomImporter:_refreshMods`) so a status change (e.g. a new conflict)
+  shows without waiting for a reload.
+- `LauncherMods.installZip(path)` mounts the archive with
+  `love.filesystem.mount`, locates the mod root via `locateRoot` (manifest at
+  the zip root, or inside one top-level folder), validates its manifest, and
+  copies the tree into the save-dir `mods/<id>/` before unmounting. Rejects a
+  duplicate of an already-installed mod id, and accepts either an external
+  path string or a LOVE `DroppedFile`, staging a dropped file into a save-dir
+  temp first (mount only reaches save-dir-relative paths), the same way
+  `RomImporter` handles a dropped ROM. A failed copy rolls its partial tree
+  back, and every path unmounts and clears the staged temp file.
+- `LauncherMods.uninstall(id)` removes `mods/<id>/` and clears
+  `options.mods[id]` so a later reinstall starts from the loader's default
+  (enabled). The mods panel Delete control calls this and re-derives the list.
+
+## Import / Export save
+
+The SAVE FILES card wires a raw Gen1 `.sav` battery image to the save slots
+through `src/import/SaveFileIO.lua`, which sits on top of
+`src/save_convert/SaveConvert.lua` and the slot API in `SaveData`.
+
+- **Import save** is live once the game's ROM is imported (playable). It opens
+  a native `.sav` picker (`chooseSav` on desktop; on Android,
+  `love.system.pickFile("sav")` → `picked_save.sav`, same SAF path as ROMs).
+  `SaveFileIO.importToSlot` reads the bytes (an absolute path, a save-dir
+  relative name, a dropped LOVE file, or raw bytes),
+  guards the 32768-byte size, runs `SaveConvert.importSav` (which also rejects
+  a bad main-data checksum), then registers a fresh slot (`SaveData.createSlot`),
+  writes it (`SaveData.writeSlot`), and makes it active (`SaveData.setActiveSlot`).
+  The meta stamp is re-stamped off `gen1_import` to the current numeric format
+  so `SaveData.load`'s migration pass accepts the slot. On success the SAVE SLOT
+  panel is refreshed with the new slot selected.
+- **Export save** is live only when the active slot actually holds a save
+  (checked against `listSlots`). `SaveFileIO.exportActiveSlot` loads the active
+  slot, encodes it back with `SaveConvert.exportSav` (a slot never keeps
+  `rawImport`, so this is a zero-filled template export, which is valid), and
+  writes `exports/gen1recomp-<version>-<slotId>.sav` in the save directory
+  (`love.filesystem.createDirectory("exports")`). On desktop it returns the
+  absolute path (`love.filesystem.getSaveDirectory()`), which the notice line
+  shows with an "Open folder" affordance (`love.system.openURL("file://" .. dir)`).
+  On Android the bytes are also staged as `pending_export.sav` and
+  `love.system.createFile(suggestedName)` opens `ACTION_CREATE_DOCUMENT` so the
+  player can save to Downloads / Drive / etc.; on return `export_done.flag`
+  makes focus show "Save exported."
+- **Drag-drop.** `filedropped` routes a `.sav` to the import path for the
+  currently active game tab; when a non-game tab (mods, or the locked yellow
+  placeholder) is showing it defaults to red, the always-present first game
+  (`_savedropTarget`). `.gb` (ROM) and `.zip` (mod) routing is unchanged.
+- **Failure UX.** Every error path (wrong size, bad checksum, write failure,
+  nothing to export, ROM not imported yet) surfaces as a red notice line on the
+  card. Nothing raises and nothing silently no-ops.
+
+`SaveFileIO` is love-free enough to unit-test through the same in-memory
+filesystem stub the slot backend uses (`tests/engine/save_file_io_tests.lua`).
+
+## Responsiveness
+
+Every measurement derives from `love.graphics.getDimensions()` each frame
+plus the existing global scale `s = clamp(height / 768, 0.7, 1.6)`; nothing
+assumes a fixed window size. The game panel's two-column grid (ROM/SAVE
+FILES/Play on the left, SAVE SLOT on the right) collapses to one stacked
+column, slot card below Play, when the window is too narrow for both
+`~300 * s`-wide columns. The save-slot list and the mod list both scroll
+(wheel, or drag on touch/desktop) clamped to their own content extent,
+recomputed every draw. The tab bar labels only the active chip so it stays
+narrow-safe, and content caps out at `~1440 * s` wide, centered.

+## Rendering pipelines
+
+Most registries hand the engine *content*. `render_pipelines` hands it
+*drawing*: a pipeline is a display mode a mod owns, which may replace the
+overworld's world pass with geometry of its own and/or post-process the
+finished image. `mods/voxel_world` is the worked example — a 3D diorama
+overworld plus a tilt-shift miniature pass, in about 120 lines of glue over
+its renderer.
+
+A record declares what the mode *is*; the engine
+(`src/render/Pipelines.lua`) supplies everything about *being a display
+mode*: the OFF/1/2/3 ladder, an options row next to TILT, a hotkey,
+persistence in `save.options.pipelines`, and the rule that a world pipeline
+and the engine's own TILT are mutually exclusive.
+
+```lua
+mod.content.render_pipelines:register("diorama", {
+  label = "DIORAMA",                    -- options row label
+  levels = { "OFF", "15", "35", "50" }, -- ladder; defaults to OFF/ON
+  hotkey = "6",                         -- checked after the engine's keys
+  priority = 20,                        -- highest eligible wins the world
+  available = function() return Renderer3D.ok() end,
+  update = function(dt, level) Camera.ease(dt, level) end,
+  drawWorld = function(ctx) return renderScene(ctx) end,
+})
+```
+
+Three draw stages, each optional; a record needs at least one:
+
+| stage | signature | runs |
+| --- | --- | --- |
+| `drawWorld` | `(ctx) -> canvas \| nil` | instead of the flat/tilt world pass |
+| `worldPresent` | `(canvas, ctx) -> canvas` | over the world, **before** the UI composites |
+| `present` | `(canvas, ctx) -> canvas` | over the whole frame, world and UI alike |
+
+`worldPresent` is the one to reach for when an effect must leave dialog
+boxes and menus crisp — a depth-of-field or colour grade on the world only.
+`present` is for effects that genuinely own the screen, like a CRT curve.
+
+`ctx` carries the frame: `state`, `cam`, `vw`/`vh` (world-pixel view),
+`width`/`height` (window pixels), `scale`, `level`, `paletteFor(map)` and
+`spriteColors(map)`. It also carries `ctx.drawFx(project, scale)` — call it
+with your own projection and the engine draws every active field effect
+(the "!" bubble, the Poké Center heal machine, the Fly bird, the fishing
+rod, Rock Tunnel darkness) at its correct anchor under your camera. There
+is exactly one copy of each effect, so a new engine effect works in your
+pipeline without you touching anything.
+
+Three rules worth knowing:
+
+- **`gate` governs input, never the draw.** It decides whether the player
+  may *change* the mode (default: free-roam overworld only). A mode that
+  stopped rendering during a warp would flash the flat 2D world every time
+  the player walked through a door.
+- **`available` is re-read every frame** and is the only thing that decides
+  whether the mode can render at all. Answer `false` on a headless run or a
+  driver with no depth canvas and the engine silently keeps the vanilla 2D
+  path — which is why shipping a pipeline enabled is safe.
+- **A callback that throws retires its pipeline**, attributed to your mod in
+  the manager's error feed, and the frame falls back to 2D. A broken
+  renderer costs the player a display mode, never the game.
+
+Returning `nil` from `drawWorld` is a normal answer meaning "not this
+frame"; the engine draws the vanilla world instead.
+
+## Battle sprite scaling
+
+The enemy's front pic draws at 1x and the player's back pic at 2x, the way
+the Game Boy did. A mod can override either, per species or per image.
+
+Per species, on the `pokemon` record:
+
+```lua
+-- MEW's back pic renders 1.5x; its front pic is untouched
+mod.content.pokemon:patch("MEW", { battleScaleBack = 1.5 })
+```
+
+`battleScaleFront` scales the enemy pic, `battleScaleBack` the player pic;
+both take a number in `0.25 .. 4.0`.
+
+Per image, on the `battle_sprite_scales` registry, keyed by the asset path
+exactly as the data references it:
+
+```lua
+mod.content.battle_sprite_scales:register("abra_back", {
+  path = "assets/generated/battle/back/abrab.png",
+  scale = 1.5,
+})
+```
+
+An image-level entry beats the species scale for that one pic, and it is
+the only way to scale a pic that is not species-keyed — the player's
+trainer back sprite, held on screen until "Go!", is a bare image path.
+
+The resolution order at draw time is **image-level → species-level →
+default** (1x front, 2x back).
+
+- **The pic stays grounded at every scale.** The player pic keeps its feet
+  flush on the text-box top (`y = 96`); the enemy pic keeps its bottom edge
+  and horizontal centre pinned in its 7×7 slot. A larger pic grows upward
+  and outward from that anchor, never off the shelf.
+- **Scaling composes with the send-out grow.** The `AnimateSendingOutMon`
+  ball-to-pic grow multiplies your scale through each stage, so a rescaled
+  mon still grows into place from the ball, grounded the whole way.

+# Updater
+
+A fused build (`love.filesystem.isFused()` true) ships a bundled `game.love`
+baked into the executable, but that bundled copy is only ever the *fallback*.
+On every launch, before anything else runs, `Boot.run` (`src/update/Boot.lua`)
+looks in the save directory's `updates/` folder for a downloaded
+`gen1recomp-X.Y.Z.love` payload that is both strictly newer than the bundled
+engine version and runnable on this shell. If one qualifies, it is mounted
+over `/` (so its files win over the fused source for every subsequent
+`require`) and chainloaded in place: the payload's `main.lua` and `love.load`
+run as if they had shipped in the executable. A dev/source checkout is never
+fused, so `Boot.run` no-ops there and the working tree always runs itself.
+
+The pieces are deliberately layered so the risky part is small. `Boot.select`
+is a pure function (no `love.*` calls) that, given probed candidates and the
+bundled `engine`/`shell`, decides what to run and what stale payloads to
+delete. `Boot.probePayload` mounts one archive at an isolated mountpoint and
+reads its `src/core/Version.lua` with `loadstring` (never `require`, so it is
+never cached as a module) to learn its `engine` and `minShell`. `Boot.run`
+orchestrates the crash guard, enumeration, selection, and the mount +
+chainload, with full rollback on any failure. Checking for and fetching a
+new payload is a separate, slower path: `src/update/Check.lua` is a thin
+main-thread state machine the launcher screen polls, while the curl calls,
+JSON parsing, and sha256 verification run on a background `love.thread`
+(`src/update/check_worker.lua`) so a hung network call never blocks a frame.
+
+## Version.lua fields
+
+`src/core/Version.lua` carries three fields the updater reads directly (the
+existing `modApi`, `linkProtocol`, `saveFormat`, and `cache` fields are
+untouched):
+
+- `engine` - the semver release, e.g. `"1.4.0"`. The repo default is the
+  `"0.0.0-dev"` placeholder; CI stamps the real `X.Y.Z` into the packed
+  `game.love` only, never the working tree. A `"0.0.0-dev"` engine always
+  reports itself up to date (it never chases a release, and it never counts
+  as a valid payload to chainload).
+- `shell` - the native-shell contract this build's fused executable
+  implements.
+- `minShell` - the lowest shell contract required to *run* this payload.
+
+Bump `minShell` only when a payload needs something the currently-shipped
+native shell cannot provide, for example a LOVE version bump, a new required
+system binary, or a change to `love.run` itself (see Known limitations
+below). An older shell refuses to chainload a payload whose `minShell`
+exceeds the shell it provides; `Boot.select` keeps that payload in `updates/`
+rather than deleting it, in case a future shell upgrade can run it, and
+`Check`'s worker reports `needs_full` so the player is pointed at a full
+installer instead. Do not bump `minShell` for an ordinary Lua/data release;
+that is exactly the case the updater exists to avoid a reinstall for.
+
+## Release assets
+
+Each tagged release `vX.Y.Z` carries the existing per-platform archives
+(`gen1recomp-X.Y.Z-macos.zip`, `-windows.zip`, `-linux.zip`,
+`-android.apk`) plus two assets the updater itself consumes:
+
+- `gen1recomp-X.Y.Z.love` - the payload, matched by the exact pattern
+  `gen1recomp-<version>.love` (see `isPayloadName` in `Boot.lua` and
+  `Check.parseRelease`).
+- `sha256sums.txt` - `shasum -a 256` output (`<hex>  <filename>`, bare
+  filenames) covering at least the `.love` payload. `Check.parseSums`
+  tolerates a leading `*` binary marker and a `./` prefix but expects the
+  filename otherwise to match the asset name exactly.
+
+A release missing either asset is treated as "no in-place update available":
+`Check` reports `needs_full` and sends the player to `Check.releaseUrl()`
+(`https://github.com/bryanthaboi/pokemon-gen1-recomp-project/releases/latest`).
+
+## Save-directory layout
+
+Under the save directory (identity `pokemon-love2d`):
+
+```
+updates/gen1recomp-<X.Y.Z>.love   downloaded payload(s)
+updates/pending.txt                crash-guard marker
+```
+
+`pending.txt` holds the filename of the payload currently being chainloaded.
+`Boot.run`'s `chainload` writes it immediately before mounting, and removes it
+on both a successful handoff and a clean rollback. If it is still present the
+*next* time `Boot.run` starts, the previous boot died mid-handoff, so that
+named payload is distrusted: it and the marker are deleted before candidates
+are enumerated. Boot may still fall back to an older valid payload, or to the
+bundled game, in that case.
+
+## Update flow
+
+1. **Boot** (every launch, fused builds only): crash-guard check, enumerate
+   and probe every `updates/*.love`, pick the highest engine that is
+   strictly newer than the bundled one and whose `minShell` this shell
+   satisfies, delete stale payloads, chainload the winner (or run the
+   bundled game if none qualifies).
+2. **Check** (launcher screen): `Check.start()` kicks off an async check
+   against the GitHub releases API; safe to call every frame, it is a no-op
+   once a check is in flight or has reached a terminal state. `Check.state()`
+   reports `idle | checking | uptodate | available | downloading | ready |
+   needs_full | error` plus the latest version and download progress.
+3. **Download + verify**: on `available`, `Check.download()` tells the
+   worker to fetch the payload, polling the growing `.part` file for
+   progress. On completion the worker re-fetches `sha256sums.txt`, verifies
+   the payload's sha256, and probes it with `Boot.probePayload` to gate its
+   `minShell` against this shell's `shell`. A verified, runnable payload is
+   renamed into place and reported as `ready`; anything else reports
+   `error` or `needs_full` and leaves `updates/` clean.
+4. **Restart to apply**: a `ready` payload just sits in `updates/` until the
+   player relaunches; the next launch's Boot step (1) is what actually
+   mounts and runs it. There is no in-session hot-swap.
+
+## Known limitations
+
+- **`love.run` persists across handoff.** By the time `chainload` runs, the
+  bundled `love.run` has already returned its stepper to LOVE; redefining the
+  global `love.run` from the payload's `main.lua` does not affect the loop
+  already driving the frame. A payload that must change `love.run` itself
+  needs a `minShell` bump so an older shell refuses to chainload it rather
+  than running with half its intended behavior.
+- **Android has no in-app download transport yet.** `check_worker.lua`
+  shells out to curl for both the release check and the download; curl is
+  absent on Android, so `Check` degrades to `status = "error"` there (the
+  launcher UI hides on that status) and the player is directed to the
+  releases page via `Check.releaseUrl()` instead.
+- **Dev/source runs never self-update.** `Boot.run` returns immediately when
+  `love.filesystem.isFused()` is false, and a working tree's `engine` is the
+  `"0.0.0-dev"` placeholder that always reports up to date, so a source
+  checkout is always "the game" itself; updating it means pulling the repo.

-The current importer has desktop file pickers only. A production Android
-release still needs a Storage Access Framework handoff that passes the chosen
-ROM to LÖVE; the APK packaging itself is data-free.
+ROM / mod / save import on Android uses `love.system.pickFile([kind])` →
+`GameActivity.showFilePicker` (Storage Access Framework), which copies the
+chosen file under the app save directory as `picked_rom.gb`,
+`picked_mod.zip`, or `picked_save.sav`. `RomImporter` imports pending files
+from that folder on Choose / refocus; see `docs/launcher.md`. The APK payload

+# Silly Oak Intro Example
+
+Hooks Oak's NEW GAME speech: extra questions, sprite swaps (Oak, rival,
+player, MEW, and a custom Toast Kid pic), and answers stored in `mod.save`.
+
+## Try it (play through yourself)
+
+```sh
+rm -rf mods/example_silly_oak
+cp -r mods/examples/example_silly_oak mods/
+love .
+```
+
+Then **NEW GAME** and mash A / pick the menus. Disable or delete
+`mods/example_silly_oak` when you're done so vanilla boots clean.
+
+## Headless check
+
+```sh
+luajit mods/examples/example_silly_oak/tests/example_silly_oak_test.lua
+```
+
+## Auto driver (screenshots + save asserts)
