-# 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 import
-
-On Android, `love.system.pickFile()` opens the Storage Access Framework
-picker (`GameActivity.showRomFilePicker`); the chosen file is copied to
-`picked_rom.gb` in the app save directory. `RomImporter` then imports on
-refocus / Choose 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).
-After a successful import the consumed save-dir `.gb` 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.
-
-## 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.
-
-## 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.
-
-## 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`, the per-OS dialogs mirror `chooseZip`;
-  Android has no picker and shows a drop hint). `SaveFileIO.importToSlot`
-  reads the bytes (an absolute path, 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")`). It returns the absolute path
-  (`love.filesystem.getSaveDirectory()`), which the notice line shows with a
-  desktop "Open folder" affordance (`love.system.openURL("file://" .. dir)`).
-- **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 boot shell: the heart of the self-updater.  A fused build, before it
--- runs the game bundled inside it, looks in its save directory for a newer
--- payload (a downloaded gen1recomp-X.Y.Z.love), and if one is present and
--- runnable, mounts it over the bundled source and chainloads it -- so the
--- binary shipped once can keep updating the Lua it runs without a reinstall.
---
--- Only a fused build self-updates.  A dev / source checkout IS the game, so
--- Boot.run is a no-op there.
---
--- Three pieces, deliberately layered so the risky part is small and the
--- decision part is testable:
---   * Boot.select     -- pure: given probed candidates + the bundled version,
---                        decide what to run and what to delete.  No love.*.
---   * Boot.probePayload-- read one archive's advertised version, isolated.
---   * Boot.run        -- orchestrates: crash-guard, enumerate, select, and
---                        (if a payload wins) mount + chainload with full
---                        rollback on any failure so the bundled game always
---                        boots.
---
--- Known limitation: the bundled love.run keeps driving the frame loop after a
--- handoff (it has already returned its stepper to LÖVE; redefining the global
--- love.run does nothing to the running one).  A payload that must change
--- love.run itself therefore requires a minShell bump so an older shell refuses
--- to chainload it.
