sudacode 1d3f099e44 docs: refresh architecture and development docs
Update docs content to match current launcher/plugin/runtime structure and fix stale home demo media assets with cache-busted URLs plus poster refresh. Add supporting backlog/subagent tracking records and docs asset regression coverage.

# Development
## Prerequisites
- [Node.js](https://nodejs.org/) (LTS)
- [Bun](https://bun.sh)
## Setup
```bash
git clone --recurse-submodules https://github.com/ksyasuda/SubMiner.git
cd SubMiner
# if you cloned without --recurse-submodules:
git submodule update --init --recursive
make deps
# or manually:
bun install
(cd vendor/texthooker-ui && bun install --frozen-lockfile)
```
## Building
```bash
# TypeScript compile (fast, for development)
bun run build
# Generate launcher wrapper artifact
make build-launcher
# output: dist/launcher/subminer
# Full platform build (includes texthooker-ui + AppImage/DMG)
make build
# Platform-specific builds
make build-linux # Linux AppImage
make build-macos # macOS DMG + ZIP (signed)
make build-macos-unsigned # macOS DMG + ZIP (unsigned)
```
## Launcher Artifact Workflow
- Source of truth: `launcher/*.ts`
- Generated output: `dist/launcher/subminer`
- Do not hand-edit generated launcher output.
- Repo-root `./subminer` is a stale artifact path and is rejected by verification checks.
- Install targets (`make install-linux`, `make install-macos`) copy from `dist/launcher/subminer`.
Verify the workflow:
```bash
make build-launcher
dist/launcher/subminer --help >/dev/null
bash scripts/verify-generated-launcher.sh
```
## Running Locally
```bash
bun run dev # builds + launches with --start --dev
electron . --start --dev --log-level debug # equivalent Electron launch with verbose logging
electron . --background # tray/background mode, minimal default logging
make dev-start # build + launch via Makefile
```
## Testing
CI-equivalent local gate:
```bash
bun run tsc --noEmit
bun run test:fast
bun run test:launcher:smoke:src
bun run build
bun run test:smoke:dist
bun run docs:build
```
Common focused commands:
```bash
bun run test:config # Source-level config schema/validation tests
bun run test:launcher # Launcher regression tests (config discovery + command routing)
bun run test:launcher:smoke:src # Launcher e2e smoke: launcher -> mpv IPC -> overlay start/stop wiring
bun run test:core # Source-level core regression tests (default lane)
bun run test:fast # Source-level config + core lane (no build prerequisite)
```
Dist-level tests are now an explicit smoke lane used to validate compiled/runtime assumptions.
Launcher smoke artifacts are written to `.tmp/launcher-smoke` locally and uploaded by CI/release workflows when the smoke step fails.
Smoke and optional deep dist commands:
```bash
bun run build # compile dist artifacts
bun run test:smoke:dist # explicit smoke scope for compiled runtime
bun run test:config:dist # optional full dist config suite
bun run test:core:dist # optional full dist core suite
```
`bun run test:subtitle` and `bun run test:subtitle:dist` are currently placeholders and do not run an active suite.
## Config Generation
```bash
# Generate default config to ~/.config/SubMiner/config.jsonc
make generate-config
# Regenerate the repo's config.example.jsonc from centralized defaults
make generate-example-config
# or: bun run generate:config-example
```
## Documentation Site
The docs use [VitePress](https://vitepress.dev/):
```bash
make docs-dev # Dev server at http://localhost:5173
make docs # Build static output
make docs-preview # Preview built site at http://localhost:4173
```
## Makefile Reference
Run `make help` for a full list of targets. Key ones:
| Target | Description |
| ---------------------- | ---------------------------------------------------------------- |
| `make build` | Build platform package for detected OS |
| `make build-launcher` | Generate Bun launcher wrapper at `dist/launcher/subminer` |
| `make install` | Install platform artifacts (wrapper, theme, AppImage/app bundle) |
| `make install-plugin` | Install mpv Lua plugin and config |
| `make deps` | Install JS dependencies (root + texthooker-ui) |
| `make generate-config` | Generate default config from centralized registry |
| `make docs-dev` | Run VitePress dev server |
## Contributor Notes
- To add/change a config default, edit the matching domain file in `src/config/definitions/defaults-*.ts`.
- To add/change config option metadata, edit the matching domain file in `src/config/definitions/options-*.ts`.
- To add/change generated config template blocks/comments, update `src/config/definitions/template-sections.ts`.
- Keep `src/config/definitions.ts` as the composed public API (`DEFAULT_CONFIG`, registries, template export) that wires domain modules together.
- Overlay window/visibility state is owned by `src/core/services/overlay-manager.ts`.
- Runtime architecture/module-boundary conventions are documented in [Architecture](/architecture); keep contributor changes aligned with that canonical guide.
- Linux packaged desktop launches pass `--background` using electron-builder `build.linux.executableArgs` in `package.json`.
- Prefer direct inline deps objects in `src/main/` modules for simple pass-through wiring.
- Add a helper/adapter service only when it performs meaningful adaptation, validation, or reuse (not identity mapping).
